Primes Don't Do That

Summary:

The worst or best pairing run of the Primes you have ever seen...

Chapter 1: OnyxAmal - Mounting

Summary:

Beastformer and shapeshifter equals one hell of a time.

Onyx pranced and kicked up loose metal like a bucking bronco. The deep brown and gold centaur-esque Prime was snorting and grunting with his wings flexing, wanting to twitch every so often. He was pissed and excited.

The free form of Amalgamous was taunting him. His yellow electricity and free flowing parts that hovered around their respective areas moved considerably now. A sign of blatant disregard for Onyx's rising eagerness. The two arms on his back gestured towards Onyx while his main arms were slack on his hips.

He then reverted to his condensed Cybertronian form, all the loose floating panels combining to a solid form and his electric interior was hidden from sight, only reflected by the yellow of his optics and bio lights. The extra arms on his back shifting to instead be kibble. His pronounced smile had a hint of canines to match his mischievous behavior. His rows of small horns were equally a reminder of his real form.

Onyx was waiting; Amalgamous knew the drill. Whenever Onyx wanted to frag, he would summon Amalgamous. He was one of the few Primes who could take his rough treatment, and Onyx was in a very rough mood.

Stomping his front left hoof, he sneered, "Amal, I hope you're prepared."

The shapeshifter hummed cockily, "Never."

Onyx trotted closer and revealed his spike near the farther end of his horse-like underside. Huffing, he was desperate to use it and frag Amalgamous to the ground. His needs only grew watching the faded gold and bronze mech reveal his glossy valve adorned with yellow bio lights.

Amalgamous climbed up in front of a low-rise platform near Onyx's lounge berth and had his back facing the other. Onyx came closer seeing him place his knee on the bar below the platform and hiking his other leg to rest on top of it, giving the beastly Prime an excellent view and access to the already dripping valve. Amalgamous seemed to have been anticipating this for the day. It made Onyx flash a mouthful of fangs. He enjoyed the brief show of Amalgamous reaching back and stroking his valve petals.

With a growl, he raised up on his hind legs and let his forelegs catch to straddle Amalgamous' sides. His spike swiftly entered, earning him a hiss and a momentary groan. Unlike the other Primes who had normal body structures, Onyx's centaur self was not subtle with its range of motion. He couldn't pace his hip thrusts. His thrusts were sharp, strong and went deep quickly, painful for most types of bots but Amalgamous loved it.

He purred as he gave a thrust every other few seconds, sending the spike jabbing hard into Amalgamous' inner abdomen. His lover grunted and snarled in a pleasurable way, jolting each time the spike snapped forward. His opening could take it.

Onyx gripped the pillars between their space with his heavy claws, panting as he managed to make the thrusts now once every other second. Tight, so damn tight. He closed his optics and focused on the body below him gripping the platform.

"F-Frag, umph! Mmph!" Amalgamous cried, "Yes!"

The harsh thrusts were snapping into Amalgamous like a whip. The beastformer only had so much he could take. His stamina was slightly different; he aimed only to overload himself. Amalgamous tried to meet against the rut regardless of this knowledge. Onyx felt heavy and drowning in bliss until the dam broke.

Suddenly, a horse-like roar echoed as Onyx overloaded and staggered back, letting go and slipping out of the other mech. He had so much transfluid, it filled Amalgamous and spilled out on the ground for a good couple of seconds upon being free of the constrictive heat. His body didn't like to hold back and felt like an asshole leaving his lover gaping and unfinished, but Amalgamous didn't seem to mind the quick overload because he went right to work finishing himself off.

Onyx stared among his cooldown at Amalgamous fingering his pretty valve. Onyx's transfluid was getting everywhere the faster he pumped. It made the beastformer horny again. Amalgamous' form threatened to dismantle as he clawed the platform he was laying his chest on, valve solely for Onyx's sight only.

Heavy sounds and leaning up to arch gave Onyx a splendid view of his lover's orgasm. Amalgamous took out his digits briefly with a gasp, letting the transfluid and his lubricant spill out before returning them to rub at his valve to stimulate another quick rush then succumbing to his body's needs. Onyx's animal intincts were kicking up with the urge to take him again.

Amalgamous finally looked at Onyx with his yellow optics pulsing, "I love it when you're like this, but I don't think I'm full yet."

The centaur purred as Amalgamous climbed down to sit on his calves, letting the transfluid leak out tauntingly slow. He then went on all fours and shifted parts of his back to give himself a reptile-like tail, wagging it alongside his aft to show off. It was enough for Onyx to immediately prance and stand over him, placing his servos on the pillar in front of them as Amalgamous grabbed his spike. It was brought to the gaping valve full of cum.

Onyx grunted as his spike was forced into his lover but let Onyx wiggle it as deep as he wanted and pumped it in and out of him at his own pace. The beastformer wanted so bad to kneel on his front legs and pin him to thrust hard, but it was only fair to let Amalgamous take charge a few times too.

One thing was for certain, he was going to fill every part of him with as much transfluid as possible before they were done.

Notes:

Amalgamous would absolutely morph himself to fit anyone. He's kind of a whore that way...

Chapter 2: MegaSolus - Double Ended

Summary:

Megatronus finds out Solus has an idea to spice things up.

With harsh breaths, the two were intertwined with Solus covered by Megatronus’ larger form. The black and blood orange Prime growled possessively at the sight of his lover responding to his spike breaching her valve. He always loved hearing her moans each time he thrusted deep into her. Even when he made her overload, she was the most beautiful thing.

Sometimes, they would switch things up. He had masturbated to her more than anyone, and she knew it. Solus would purposefully display herself so he could come around and claim her when she “didn’t expect it.” It was all fun and games. Until there was one thing he kind of didn’t know what to think of.

“Solus, what are you doing?”

The purple and gold femme grinned, “Just thought I’d, mmph, test this new toy I found.”

Megatronus raised a brow as she pumped the flexible object into herself leaning up against the wall of her workshop. He then said, “My love, if you wanted to play, all you had to do was ask.”

She pulled it out with one end covered in lubricant a little embarrassed. Megatronus noticed it was phallic in shape but double ended.

“You want to try it?”

The question threw him off greatly. A heavy blush hit his features upon recognizing her proposal and couldn’t find the words he needed. “I-I, well, I’m not familiar with toys like that. I, uh...what do you propose?”

He peered down at her feeling very weak in the knees as she commanded, “Lay on the table and open your valve for me.”

Her workshop table was huge with tools scattered about that were easily knocked off. He crawled on it and she followed. With uncertainty, he let her settle between his legs and opened his valve curious. He shivered when the end she had been working on already lubed up slipped slowly into him. He let the intrusion settle before she started pumping it into him.

The feeling was strange at first but arousing. He felt it stretch his walls and rub across his nodes at a pace that made him give a timid laugh, then it melted to a moan. The slick toy pushed deeper with Solus at the reins. It made his walls ripple and contract. The smoothness made it easier to flow against his insides. He laid back and tried to arch as Solus increased the pace to watch his reaction.

Then she stopped and he looked down his body to see her align herself with her legs over his. She briefly smiled until the exposed end of the toy breached her and made the sweetest noise. Megatronus saw what she intended to do and let her grab his thighs to drag herself onto the remainder until their valves were flush against one another.

Megatronus closed his optics, settling back down again with a wanton gasp as Solus started to pull out and then move back towards him. The toy moved inside him, and he just let her take charge to show him the new experience. His valve folds constantly met her own, exchanging fluids amid their clashes from how much their bodies produced to accommodate the toy. He responded back by copying her. The results were electrifying.

Solus became more demanding and gyrated her hips to snap against him. The toy was pushed harder, deeper and antagonized the nodes that made Megatronus meet her halfway in desperation.

"Look at you, Megatronus,” she purred, “taking it like a Prime.”

The taunt made Megatronus buck to bounce his valve against hers. The toy was barely visible between them. He sat up to let Solus shorten the space by meeting him until the thrusts stopped and their valves were completely together. Solus didn’t let him move, seating herself to torture him in a standstill.

“Solus...”

“Yes, my dear?”

“Please,” he all but whimpered when she moved her hips in a circular motion. It made the toy try to move and her valve petals teased his.

Solus seemed to contemplate his plea before suddenly making hard, sharp motions that made both of them grunt. Megatronus welcomed the rough thrusts and laid back down arching. His chassis jolted with each pounding. The toy prodded his deepest sensors that made him grow one step closer to his orgasm building.

Solus’ servo held onto the toy once it was mostly in Megatronus and bounced herself on it with a devious agenda. He was too enamored with his filled valve that he didn’t mind his lover fucking herself on the toy they shared. Each vibration shook him to his core until his body could take no more.

He cried out and mapped his quivering abdomen plagued by spasms. Solus followed with a slam of her hips to trap the toy among their touching valves. It added an extra motion of pleasure to Megatronus’ ravaged form.

Solus pulled herself off and climbed over to him. He kissed her feverishly in the wake of her overload until she moved back a little and a new moan escaped him when the toy began to move. She tried to stuff it entirely in him; Megatronus only encouraged it with a slow roll of his hips. He suddenly bucked when Solus lowered her helm to his leaking valve. Her lips took the head of the toy and pushed it to keep it in him as she also began eating his valve. The deep toy and assault on his valve lips built up his pleasure tenfold. He was all but shouting loudly and spasming hard from her motions.

Megatronus sometimes questioned Solus’ tactics in their interface sessions, but she always had a knack for proving his doubts wrong. He had been unsure of this toy. Now, he couldn’t get enough of it. He understood why she liked it.

Notes:

I refuse to believe Megatronus and Solus wouldn't be kinky as shit in their coupling.

Chapter 3: PrimaVector - Portal Sex

Summary:

Vector's portals are not to be played with or are they?

Vector threw a planetary sphere of his star system display up and spawned a portal effortlessly to capture it. He then formed another to make the sphere pop out and one more to capture it again on the opposite side where it flew to. Like a ping pong game, portals appeared to his left and right, right to left throwing the sphere out and catching it back in as his form of juggling. He was showing off, in Prima’s opinion. Finally, a portal appeared to face Vector instead and threw the sphere at him which he effortlessly caught in his servo. He put the sphere back to hover in its alignment of the model it was taken from.

Prima grew intrigued and asked, “What else can it do?”

Vector opened a portal beside him and then made one spawn adjacent gesturing, “Do whatever you see fit. What you throw in one vortex will come out the other.”

Prima stuck his servo through and saw his servo pop up adjacent waving at himself. He pulled it back out in awe. Then he got the idea to lean into it, making his arms and torso appear in the other portal but left his bottom half bent over. He saw Vector stare a little baffled and laughed at the mech.

“I take it you’ve pulled a few pranks with this.”

“You think I would waste my power on pathetic pranks?” The silver, gold, and maroon mech seemed insulted.

Suddenly, Vector gestured and the portal grew smaller until it only was big enough to hold Prima’s waist. Prima tried back out but found himself stuck, his lower half mirroring his struggle in front of him.

“Vector, release me-”

“Oh, why would I do that? I would never use it for pranks, but I would put it to good use teaching those who misuse my creations some manners,” Vector said reaching out to caress Prima’s aft. “An example of what happens when you play around...”

The leader of the Primes was forced to see himself getting groped, unable to do anything but bite his lip. Vector aligned his cod piece to Prima’s aft, holding his hips. He used his servos to trail up to Prima’s cut off mid waist in the portal back to the hips again. Prima made a small noise making Vector peer to the side where his upper half was.

“Something you want to say, Prima?”

The white and silver mech hissed, “You know damn well what I want to say to you right now.”

Vector grinned, “Maybe so.”

Immediately, Prima gasped when Vector pressed against his aft and retracted his spike panel. The spike rutted among Prima’s closed valve, and he watched this display heated and with a groan. The problem that began to form was he became aroused by his own shame. Even though he could feel it, seeing it made his processor believed he was interfacing with a phantom while viewing a pornographic rendition. He was a voyeur to himself.

He pressed back against Vector humping him as little as he could, listening to the possessive raptor-like growls of the other mech getting off from his predicament. Prima then retracted his valve panel and was instantly shook when the spike’s side slid across his folds.

“Primus, Vector!”

The other Prime didn’t respond at first and instead leaned forward to clutch Prima’s hips to just go at it. Prima was humped with his valve forced to spread against the length teasing him but never penetrating. He whined when Vector abruptly released onto his valve petals, marking them. Squirming as the transfluid ran down his inner folds and over his exterior node, Prima felt Vector manually spread his valve to let more of the fluid run down his entrance and saw the mech have a perverse sense of admiration of the display.

Vector hummed, “Well, well, the great Prima loves more than just attention after all.”

Prima jeered, “But you’re too much of a coward to try and frag me when I’m not incapacitated.”

“Hmph, a coward, am I?”

The jab was costly but worth it as Prima moaned loudly when Vector’s spike pushed in with some of his fluids. He spread his legs wider and saw Vector pounding into him. The synced movements of him being fragged and seeing Vector’s enthusiasm only enhanced the pleasure tenfold.

His valve tremored alongside him. Prima secretly enjoyed it. Vector was determined to make him submissive and slammed his length to the base. The pace made Prima want to reach back and force his valve wide but remembered he was at Vector’s mercy. His only option was to take all of what was given to him out of his realm of control.

Even when he came, Vector just kept using his body as a personal pleasure toy. Prima just watched his lower half be coated in transfluid twice more. Each overload more vicious then the last. By the time Vector was done with him and widened the portals to pull him through, Prima stumbled to sit on the floor with his valve aching. He looked up at Vector while the mech leaned back with crossed arms on the desk.

“Now you know how not to use my portals,” Vector said smugly.

Prima accepted the call on his pride and couldn’t prevent the slight attraction to the response. If an option came to do it again, it was debatable if he would…

Notes:

Somebody had to do it. Sorry for the delay. I got sick and some complications kept me from posting but we are back in action. Stay tuned for more.

Chapter 4: MicroOnyx - Size Kink

Summary:

Smallest Prime meets the largest Prime.

Micronus being smaller than everyone else had plenty of downsides, but an upside was everything also looked bigger to him…and Onyx Prime was huge. Among the largest Prime, Micronus felt smaller than normal. Admittedly, a crush came onto him and he didn’t know what to do with it. He started to see things a little differently; he started to see Onyx a little differently.

It became hard to be around Onyx because of a shameful imagination he possessed wondering just how big the bot was underneath. He wanted to know so badly that when he found Onyx chilling in the Archives reading, he snuck under the bot and praised his small form for being able to do it undetected. Every archival shelf with datapads had a table so the users could sit down and read right where they were. Onyx read standing up between the shelves in front and behind him. Right now, Micronus wasn’t interested in the readings.

One of the rear legs casually lifted to balance on the tips of the split hoof-like claws. The tail swayed naturally with no sign of being alert. But the prize was the underbelly where the ribbed, protruding spike panel was. Micronus grew intrigued and reached up to caress the panel, hearing a confused grunt above and the sound of sniffing. Onyx was deducing his likeness through scent.

“Micronus...what do you think you are doing?”

The Minicon said in a trace, “I just want to know.”

He played with the panel exterior, prompting Onyx to grow unsteady. He barely heard the other’s reply.

“What has gotten into you?”

Micronus found the manual latch and was surprised as there was only a tip of a spike, that was until began to tease it. Onyx made a deep rumble and the spike suddenly extended far bigger than Micronus believed the body could hold in such a decent sized slot. The more he played with it, the more it dangled down to the floor almost as long as Micronus. The smaller Prime was gawking in eagerness and amazement.

“I don’t think I could fit this inside me...” he muttered to himself amused.

Onyx Prime warned uneasily, “Micronus, if you tread any further, you will hurt yourself.”

“Well, maybe I want you to split me open, Onyx. Admit it, you would love to squeeze your spike inside someone like me. As for myself, I’ve always wondered how much of you I can take.”

He grinned at the spike reacting well to his touches before he opened his valve and grabbed the length to curve it behind Onyx so he could sit on the table and tease his entrance with the tip. Onyx looked back at him aroused, instinctively backing up and curling his tail out of the way so his length could be unobstructed. Micronus knew he found the idea exotic.

Micronus forced the spike to breach him with a deep intake and massaged his valve exterior node to distract from the brief discomfort. Onyx was barely inside him and already too big. But gripping the spike, he eased it deeper wanting to be stretched more. Onyx gave a whinny, pedes stomping watching the spectacle of Micronus taking half of the spike inside him that shoved past the entrance to his gestation chamber and hit the roof of it before he couldn’t put in any more.

He felt bloated. Energon blood from overstretched walls made Micronus groan but start to pump the spike to hit his gestation walls repeatedly in blind pleasure that outweighed any pain he felt. He was laying back with his legs straddling the sides of Onyx’s haunches to bring him as close to Onyx as possible so none of him tried to slip out.

Jerking the spike a few times, he threw his helm back against the table riding out the tension that made his chassis respond delightfully. He saw Onyx try to go back to reading only to claw at the table and mutter curses.

Micronus laughed, “You’ve thought about this, haven’t you, Onyx? Frag, you’re so big. You’re tearing me up.”

Onyx didn’t say a word but bucked back which jolted into Micronus who let out a cry and stroked his valve petals to overcome the sting. He felt like he was one mistake away from being ripped apart but didn’t care in the slightest. The spike slid down into him as much as he could make it, pumping Onyx to make extra stimulation. He panted and moaned trying to thrust up. His full valve screamed from its limitations but he ignored them to buck against the twitching appendage.

Upon overload, he furiously stroked Onyx’s spike to get him to come, bring the spike out until only a few inches remained. An avalanche of transfluid filled him in less than a second and he accidentally triggered a second wave of pleasure. Micronus stuffed himself again until another overload hit him. Onyx gave a brutish groan when he finally let go of the spike and let it fall back to dangle near the ground.

Energon mixed with the transfluid from the slight tear in his valve from the stretch. Micronus just continued to massage himself to distract from it as Onyx turned to scold him.His valve continued leaking the fluids over the table.

“You realize you could have almost killed yourself,” Onyx panted.

Micronus smirked, “But we both liked it.”

The beastformer grew silent and shook his helm at the audacity though Micronus caught him admiring his valve full now that he proved he could take the largest Prime. He was so small compared to the other. It only turned him on more to see Onyx facing over him with his imposing stature.

Notes:

If Micronus didn't die, I'm pretty sure he would have torn his valve. But we aren't here for realism, are we?

Chapter 5: PrimaMega - Caught Masturbating

Summary:

Prima thinks he's sly but there's always someone who's done it first.

Prima felt bad, terribly so, as he listened to the Primes talk in their shared living room of their housing level and only focused on Megatronus. The strong Prime was conversing with Quintus while Prima currently had a servo pumping his spike in the shadows. What he would do for Megatronus to be with him, but a small sense of envy escaped him at the attention Megatronus was giving to everyone but him.

With a hiss, he marked a corner of the room silently and put away his spike in shame. It was out of sight, out of mind as long as no one went to that corner specifically. He tried to cover it casually with curtains just next to him in the windows before meeting up with Alpha Trion like nothing happened. He did keep an eye on Megatronus wondering what to do about his attraction to him. There was no way around it.

Afterwards, there was a meeting in their fortress across from their home building and Prima was very reluctant to go right now. He was moody and it helped none Megatronus sat two spots near to him. That was the worst decision ever in their layout. Being the de facto leader of the Primes by creation number, he sat at the head of the table. The second Prime, Vector was on his right side with the third, Alpha Trion, and so forth continuing down the line. Thirteen was on his direct left but Megatronus was right next to Thirteen. He kind of lost track what they were talking about and had little opinions himself about it, too focused and horny that he had his valve open and was stroking it beneath the table out of sight. It helped none Megatronus occasionally looked his way even when he wasn’t talking.

He kept his arm movements to entirely still, just focusing on lightly playing with himself thinking about Megatronus possibly fragging him, and he prayed to Primus silently that it would come true. He kept as still as he could, not letting anyone think something was wrong. As soon as the opportunity to wrap up the meeting was presented, he all but excused them quickly and waited for everyone to leave except...

“Prima, can I have a word?”

The larger Prime let Alpha and Thirteen pass him before letting it slide closed. That left Prima with Megatronus alone. The twelfth Prime chose Thirteen’s seat to be right next to Prima now, and that was an even worse mistake than the normal arrangement. He started rubbing himself harder. Megatronus had no idea.

“What’s wrong?” Prima asked. He felt droplets of lubricant starting to moisten his valve and his desperation climbed in his faux calm state.

“You seem out of it. You have been for the past few days. I know because I study everyone, and something isn’t right about you.”

Oh, Primus, his voice. Deep, thunderous if rageful, and demanding. Prima tried his hardest not to show he was close to coming undone as his digits now performed rapid circles over his sensitive region.

“I have no idea what you mean,” he managed to get out.

Megatronus wasn’t buying that and furrowed his brows. “Enlighten me."

Prima couldn’t take much more. To his embarrassment, he had to cover his mouth and close his optics at the painful situation he just made for himself. Megatronus saw this and his suspicion skyrocketed until he suddenly looked under the table-

“Prima...” Megatronus shot back up in disbelief but amused. “You mean to tell me the entire meeting...?”

Prima rubbed his optics with his free servo. His other had lubricant on it. He heard Megatronus sigh with a small laugh then heard the other chair move closer. Abruptly, Prima’s servo was shoved away and two foreign digits breached his entrance making him squirm and sink in his seat. Megatronus' left servo palm covered his exterior node and with his rough motions managed to simultaneously antagonize it and slam the digits into the valve. His right servo gripped Prima’s chair.

“You seem a little too excited I’m helping you. That makes me curious if it was me you were imagining,” Megatronus sneered.

He was too focused on the digits abusing his valve to make a statement about it without coming off as a hypocrite. His servo went over Megatronus’ and tried to force the digits deeper, instead prompting Megatronus to insert another digit and kiss him. He moaned into the other’s mouth and clenched his thighs as a mind-numbing overload hit him. They broke apart when Megatronus had a vicious smile with his two sets of canines making Prima blush.

“The next time you do something like this, just know some of us might be a little more familiar with such activities to know when you’re lying about it. You aren’t the first of us to do this, but I was never caught.”

That made Prima look at him stunned. “You...”

Megatronus simply mused, “Some parts of our abode aren’t as clean as you think. More specifically, I really love using that table in the lounge room when everyone is still home in the other rooms. Adds a little tension to the experience.”

Prima just stared at Megatronus walking out and made the Prime leader immediately think about that. When he finally returned to their shared tower complex, he passed Megatronus who merely winked and then he went to the lounge room only a few Primes ever truly used. There was a table with a corner of it slightly worn by some type of activity. It dawned on him Megatronus had been relieving a lot of stress on it, and he was about to as well.

As he heard the other Primes moving about, he revealed his valve again and pressed it to the corner of the table. He gripped the other edges of it to keep steady as he rocked against the newly blissful sensation. He hoped Megatronus would carry on after him; the idea of them sharing the same spot to play at only heated him further.

All Prima could do was continue and drag his valve across the corner thinking of Megatronus. While he wanted the mech to take him, this was the next best thing. And he didn’t regret being caught now.

Notes:

Megatronus was probably the third most sought after Prime behind Solus and Micronus if lore was correct. I would believe it. Who wouldn't want to be railed by this guy?

Chapter 6: AmalNexus - Orgy

Summary:

What's better than an orgy? An orgy with technically only one person with multiple counterparts.

Amalgamous had a confession to make. “Can you interface with your connected parts as individuals, or no?”

Nexus was shining the Cyber Caliber when he paused and slowly looked up at Amalgamous like he was crazy. “What do you mean? Like can I split into my five counterparts and can they interface? Yes...they have the parts. They are fully functioning...why?”

“Well, I, uh, always wondered since you and I have been experimenting, would you be opposed to taking turns with them?”

It took a moment for the blue and red mech to process that. Amalgamous’ compressed form offered a small smile in reassurance. He wanted to see if Nexus would, but he was taken aback to find a few minutes later the other very much could. It was rare that Nexus decombined but Cannonspring, Mainspring, and Clocker were immediately into the idea when they detached. Pinion and Chaindrive were a little nervous how to approach him. Four mechs and one femme to give him comfort.

The relatively normal sized counterparts surrounded the larger Prime with Mainspring, being the technical leader as the main torso of Nexus, gesturing towards the berthroom. “Amal, you want to play with us, you got us, baby.”

Amalgamous’ plates shifted up in reaction to the invitation, yellow optics glowing bright. He was escorted to lay on the berth and Mainspring was the first to tease his equipment. He wanted the valve most of all and quickly pressed two digits into the yellow bio lit entrance. Amalgamous grew flushed as the others gathered to take their places with Chaindrive shyly pulling out her spike and letting him suck on it.

Pinion and Cannonspring toyed with their spikes and offered Amalgamous the ability to stroke them while his mouth went to work. Clocker, on the other hand, valued his spike and as Mainspring worked on lubricating his valve, the other mech teased his valve to rub on the spike presented.

Amalgamous gave a soft moan, taking Chaindrive deeper into his throat and pumping the two spikes simultaneously. Chaindrive grew confident enough to thrust into his mouth with a cute whimper. Just then, he made another noise when the digits playing with his valve were replaced by a spike that slammed into him. Nexus’ components may have not been as big as a Prime, but Amalgamous adored their features uncaring of their size, only that they felt wonderful.

Clocker pinned his spike and dragged his folds on the erect member, and Mainspring wrapped his arms around Clocker’s waist so when he thrusted, it moved the other mech. Amalgamous felt his tip nudge the entrance of the teasing bot and wanted so bad to grab him and seat him on his spike, but he was too occupied to do so. But Clocker showed mercy and had Mainspring pause his motions to help the smaller mech take Amalgamous’ length.

As soon as Clocker was seated, Amalgamous worked harder on the three near his helm. Chaindrive rutted hard in his mouth with a cry of delight as he sucked her off until she came. Cannonspring pawed at his chest when he unloaded, and Pinion was still needing more attention, so Amalgamous switched to service him instead and let Chaindrive recover. Mainspring was pounding into him at a rapid pace, his interior nodes electrified. Clocker lifted and slammed down on his spike before leaning back into Mainspring who kissed him.

The many activities threw Amalgamous’ body for a loop and he arched coming closer to a fast charge he couldn’t hold back. It was torture. Pinion seemed grateful for his lust as he blew the component’s mind with some intense oral action. He eagerly bobbed his helm with muffled moans until he made the smaller mech release.

Mainspring and Clocker worked in tandem into the latter shuttered and grinded on his spike in a heated overload. Mainspring was close and Amalgamous shouted as he came from the pressure. Mainspring humped him some more and followed shortly after.

The five components looked hungry for more. Amalgamous wasn’t one to displease his lovers. He was open to anything. This time, Mainspring made him take his spike into his mouth which he accepted as Pinion shoved his spike into Amalgamous’ valve. Chaindrive and Cannonspring played with his spike, and Clocker helped Mainspring sedate him.

They rotated multiple times, each component taking turns using his valve most while a few of them impaled themselves on his length or gave him a blowjob in return. Amalgamous was in heaven with the constant attention. The berth was a sticky mess by the time they wore themselves out.

Finally, they combined to form Nexus who crawled over Amalgamous. The dull gold mech could sense Nexus trying to process all his forms’ activities that were now pushed onto him. But he understood what Nexus wanted now that the large Combiner was whole again and reached down to play with his spent valve. Nexus peered down and his engines roared to life.

“After all that, still horny for me?”

“I helped everyone but you,” Amalgamous purred.

Nexus didn’t hesitate to bring out his large spike and shoved it in. Since he was already wet from the attention of the components, the stretch of the thicker spike felt amazing as it pounded him to gush lubricant and spent transfluid with a mewl. He let himself be used repeatedly. He didn’t mind it at all for Nexus.

Notes:

Upon technicality, it's an orgy. Nexus' components are rarely used in media so I figured I'd show you some potential.

Chapter 7: AlphaSolus - Stress Relief

Summary:

Who says there's no sex in a library?

“Why is it every time I need you, you’re always in the Archives stashed away in your office?”

Alpha Trion looked up from his Covenant and set aside his Energon and Quill. He was sitting at his desk peacefully when Solus arrived. He gestured to the massive library he had a nice view of from his office window shaped like the Matrix of Leadership that was renowned for holding the greatest wisdom kept close by the Primes.

Alpha mused at that and shook his helm, turning in his chair to face the window, “Solus, I can’t just drop everything, especially with all these visions I’ve been getting of the future. Some are disturbing and keep me up for days. Some are beautiful, full of harmony and peace that some of us might not see in our lifetimes. I need to document them; it is what Primus has plagued me with as their servant of Cybertron.”

“Hmm, I can fix that...”

“Nice of you to offer, Solus, but I-”

The sound of shuffling made him turn back only to freeze as he found all his stuff had been moved to the side and instead, Solus took the place of his Covenant sitting with her legs open and her valve out. Alpha was at a loss of words, the very first time he never had anything to say. No words of wisdom for sure. Solus just leaned back slightly on one arm and puffed out her chest to show off her physique that he had a reaction to...somewhere.

“I think I have the perfect cure for fatigue, Alpha. It’s something you and I can both enjoy, and it will help you,” she purred, rubbing slow circles and making Alpha’s attention unable to leave her.

Alpha had to take a moment to gather his thoughts and try to play the sensible one. “Solus, while I appreciate the concern...I don’t think this is very appropriate...”

There wasn’t much that he could do when Solus rolled her optics and instead slipped onto his lap with her legs folded on each side of him. He was pressed against the chair unsure of where his servos were supposed to go. She rested her weight on him. He felt the outline of her equipment and struggled to process the feeling of it rubbing on him. Solus then cradled his chin and hovered her lips over his with his helm tilted to look up at her.

“I don’t think Primus will mind me borrowing their best archivist and adding some lube to keep him up and running properly.”

That popped a gasket or two. His servos hesitantly went to her waist as she reached down to paw at his interface array while grinding down on him. His engine sputtered and whined at her persistence. He finally broke and released his humble spike that he thought would be not impressive to her, only to get the immediate surprise of her grabbing it and seating herself fully with no preparation with a noise of delight.

One thing about Solus was she was not one for gentleness. Alpha Trion was stuck processing the sudden wave of arousal and tension from Solus bouncing on his lap and making his chair creak. It was not supposed to take such pressure, but he didn’t even try to tell her that. All he did was hang on to her for the ride.

He was aware if anybody looked up to his office window high above the Archives main level, they would see Solus facing backwards going down on a chair with someone in it. As far as he knew, there were only a few bots in the building and his office was soundproof for needing complete silence to focus on his work. Now, he was kind of glad it was soundproof because his spike was getting action he hadn’t obtained in years.

Her servos were clinging to the chair back and the only thing he could see in front of him, when he wasn’t closing his optics blissfully, was Solus with a passionate expression.

“Are you going to overload for me, Alpha?”

That made him groan at the rapid heat in his chassis when she went still to take every inch of him to suffocate it and press her chestplate on his chin waiting for an answer. He desperately wanted her to move again, so he all but muttered, “Y-Yes, Solus.”

Instead of numbing his lap, he was shocked and nearly came when Solus had a devious purr and sharply snapped her hips to grind on him. It felt surreal. He was dead weight in that chair for once, and he could appreciate it as Solus did all the work. His spike was about to explode in the chaos amid her cries of pleasure when she went back to impaling herself, his servos lazily holding onto her aft.

With a heavy whimper, he came and serenity rushed through him like all his burdens disappeared for a moment. Solus followed suit rocking into him. Solus was an aggressive masseuse. But he found her readjusting to lift off him and move back so she could stroke his spent spike covered in their fluids. She still had one servo on the edge of his chair beside his helm.

“I-I-I must get back to work-”

Solus then asked playfully, “Who said we’re done? Fatigue needs work. I’m going to make you sleep good tonight.”

Alpha was at a loss again but liked her hold on his aching member.

The remainder of the day, he got nothing done that he wanted to. Solus wouldn’t let him. But after having her riding him for a decent amount of time between other activities, it was safe to say...he did find time for recharge and was, for the first time, late to a meeting from sleeping past his normal schedule with no visions or disturbances. Ironically, it was the best sleep he ever had. And Solus pretended nothing happened when he saw her during that meeting. All he could think was whether or not he should perhaps take more breaks.

Notes:

Favorite one so far, not going to lie. Alpha Trion getting rode on in his chair was an image in my head for a good day or two. Solus was the perfect candidate for it.

Chapter 8: QuinAlchem - Drunk Blowjob

Summary:

Alcohol and no thought filter equals an interesting time...

“Okay, one, two, three, shoot!”

They both tipped their helms back to take a shot and slammed the cups down at the same time back on the table. Quintus was tipsy seven shots in of a dense, special blend oil the Alchemist made. His frame was thinner and less accustomed to such heavy liquids. Alchemist was also a little out of it but had a larger tolerance from years of drinking on his off days.

The green mech’s tentacles were sedated, wrapped firmly in the grooves of his waist from lack of use. The high grade made it to where they were too lax to be out lest he wanted to accidentally swing them around and hit random things. He didn’t want to ruin Alchemist’s personal bar in his chambers by letting them move uncontrollably. He just casually sat at the table letting the robe-like armor hang over his seat and prioritized his servos like normal. His four spider-like legs were fuse to two regular legs at the moment to make sitting easy though his lack of pedes that had him balancing on the thin barbed tips of what passed as pedes made using the stool’s foot bars nearly impossible, especially when drunk.

They continued doing shots. While he was silent and occasionally talked, Alchemist had stories and great things to talk about. He honestly didn’t mind the boisterous, jolly attitude. It made being around him fun. But a couple more drinks led to another perspective. It was impossible to speak his mind about it, only that while laying his chin on his folded arms looking up at the mech, he liked the view. Alchemist was oblivious to his thinking taking another shot. What he wouldn’t do for some different type of company.

He regrettably had no filter anymore in his mind and didn’t think properly about Alchemist, staring at pleasant grin and his heavy chassis on display downing another glass. Alchemist was sturdy, very large not just in personality, and Quintus was curious if everything was fun to be around about Alchemist.

“Has anyone ever offered to-to repay your kindness by fragging them or sucking your spike?”

It took him a moment to kind of make sense that he didn’t say that in his processor like he wanted. He met Alchemist’s surprised blue optics enhanced by the Lenses he naturally wore and tapped the table embarrassed realizing that was not a good thing to ask. Alchemist slowly leaned on the bar table across from him and still had an amused expression.

“No...but if I ever get a bar out in public one day, I get the feeling I might. You offering?”

Not really thinking about the repercussions, Quintus climbed onto the table without a word and kissed Alchemist. The latter didn’t fight him, just started kissing back. The lopsided feeling almost made him collapse on said table, but he was persistent at enjoying the moment. Their glossa were intertwined, deepening the affection. Quintus didn’t know if he should blame himself or the high grade. He really wanted to repay Alchemist with a newfound appreciation for the mech, and he knew just how to do it.

Quintus broke off and climbed over the bar table onto his knees silently massaging the mech’s panel. Alchemist was bigger from that point of view and he liked it. Alchemist looked down at him unsure at first but obliged his curiosity. He was a little taken aback by the thickness of the spike. For a hefty mech, Alchemist was not large in length but definitely in girth. Against Quintus’ natural slim build, he liked it.

His glossa began savoring the taste before he eased his mouth onto the spike. The rumbling from Alchemist’s small pleasurable laughs only made him continue carnally. He found no need to hide his liking anymore. Quintus bobbed his helm on the spike and had his tentacles from his back wrapped around the base of it where he couldn’t take it fully. Alchemist pet his helm and made him purr, lifting away from the spike to drag his gloss on the underside to the tip.

“I never thought I’d say this, Quintus, but you look good like this,” slurred Alchemist who was not sober either.

The drunken praise made Quintus take him again and his tentacles started helping him pump the spike. Hearing his fellow Prime groan and lean against the bar table, Quintus doubled down on his pace. He liked the taste and imagined Alchemist using it on him. If it felt like what he was getting a good mapping of, he wanted it.

The mirrors on the ceiling reflected his actions as he hungrily devoured the larger mech’s spike. Alchemist leaned forward and closed his optics when Quintus got a mouthful of transfluid that hit his chest in blotches when he couldn’t hold it all. He received another stroke around the crown-like horns on his helm, his purple optics ablaze. He wanted so much more and cuddled close.

“That’s one payment for a bottle I suppose. We have gone through three though,” hinted Alchemist.

Quintus just looked at the spike for a long minute and finally said, “I can pay off my tab-I can do it.”

Alchemist took another drink smirking, “I bet you can.”

It was more than enough encouragement for the green mech to go back to servicing his peer. The transfluid added flavor and scents of the high grade made it seem divine. As Alchemist just kept drinking and watching him reduce himself to a pleasure bot, Quintus didn’t care about the judgement. He just was needing to please Alchemist and hopefully, he would perhaps do a little more. His perception though was tipsy, so he just clung to the other’s hip and did as he wanted. Alchemist certainly had no complaints.

Notes:

Just for reference, Quintus and Amalgamous' designs are a mixture between their Aligned counterparts but they have the ability to merge their features to appear more "humanoid" at will. Quintus' four crab-like legs can because two regular while hiding his tentacles on his person and Amalgamous has the freeform variant where his parts are electrified and floating but can change to a compressed Cybertronian form to interact with the populace easier. Just in case it was difficult to imagine Quintus moving around with Alchemist, there's a little clarification.

Chapter 9: OnyxSolus - Bondage

Summary:

How to ride a beastformer.

The straps around his chassis were constricting. They were meant to be she told him.

Onyx had a reined bar gag and covering muzzle on that strapped around his horns down to the collar he wore. His chest piece was also connected off the collar and restrained his arms behind him. His wings had special restraints to not damage them but kept them folded to his side. The saddle that the straps for his wings attached to he had on the lower spine was connected by a waist harness and had decorative rope coming down across his lower half’s legs and midsection. The rear of the saddle followed his spine back to his tail where his rear legs’ straps met to a cover that held a placed plug currently stuffed deep inside him. His spike was stuck on his underbelly leaking by a harness and he couldn’t retract it.

Onyx shuttered and gave a whine beneath his muzzle with the binds on his four ankles keeping his legs apart as the plug vibrated inside him. It was torture and when he managed to bend his upper half to a degree, he noted his previous overloads with remnants on the ground of both transfluid and lubricant that had been creeping down his legs. He gave a horse-like pant as his chassis spasmed from the assault on his valve. It didn’t take long for him to be sent over the edge. His spike stained his underbelly while the rest of it hit the ground, and his valve gushed similar pushing past the plug.

“Oh, Onyx, look what you’ve done. Bad boy. You’ve made a mess,” scolded Solus. The centaur’s hide instinctively flinched at her touch pleasurably. She ran it across his right side to the front limb which she patted with a smile. “Maybe a walk will get all that excess energy out. Does that sound good while your room gets cleaned?”

Onyx liked walks and slowly nodded, unable to talk with the muzzle. Solus grabbed a rag and helped him clean his parts and legs then winced when she pushed the valve cover down to take out the toy only to replace it with another toy bigger in length but no features otherwise. He grunted and tried to moan as it was inserted. Once it was seated in him entirely, Solus strapped the cover back to keep the toy secure and went in front of him to untie the reins.

He followed her guidance like a pet but twitched his optics feeling each step unsettle the toy. Solus deliberately did this to test him. The beastformer found it hard to walk without wanting to stop and try to get off on it. His struggling persisted when they bridged to the untamed frontier of Torus Heights. They were thinking about putting a conservatory here for its wildlife but for now, it was under his protection and someplace no one had to see him be reduced to a horny mustang.

Solus suddenly mounted the saddle and held the reins while petting his shoulder. “Go on, Onyx, give me a tour.”

He treaded through the territory trying so hard not to focus on the toy shifting with every step. If he went faster than a prance, it really got bad. A few times Solus goaded him to trot faster, he only was able to do so for a moment before his legs would start to feel weak and he slowed nearly to a stop to huff and try to hump the air.

“Uh-uh, I said walk. Come on, pet, you were doing so well,” she taunted.

His rear legs were bending lower than his front with his torso leaning forward shuttering. He stood still to fight the heavy sensation rattling him until it went away. With a ragged breath through his muzzle, he continued on. It was a test of endurance. He had done it before but not with this size of a toy. It took every bit of willpower to make it to the trail end where he was always allowed to let his body cave without Solus making him endure it again as punishment.

Solus finally said, “Good boy, now overload for me.”

Onyx started to trot fast to get the ripples of pleasure go to ravenous waves. He slowed and arched, moving forward a bit before using his front legs to keep from falling and his rear bucked wildly with an assault of heat. The toy was crushing against his walls and moving. His back left leg lifted among humping automatically and stretched among his intense overload that he needed so bad. He almost wanted to cry from how good it was. Solus was just holding on like he was a bucking bronco.

When Solus got off him, Onyx was dead standing with a long growl and leaning forward tired. The orgasm alone drained much of his energy as a whipped pony for his master. He didn’t shy away from Solus’ touch. Then she whispered something that made him perk up horny again.

“Maybe if you’re good tomorrow, I’ll let you ride me."

He nearly caused another orgasm from how hard his tail was wagging. It may have been restrictive, but he would lay down his life for Solus, even reduce himself to a pet to be with her.

Notes:

This was kind of how I figured centaur bondage kind of would work and a little pet play to go with it. Onyx is sometimes the most fun to write for because he has extra features not normally found in other Transformers. I can just go ham on this dude's possibilities, and he really is a slut deep down.

Chapter 10: Prima13 - Service Top

Summary:

Thirteen finds just how good his leader is at this.

Thirteen had rode Prima’s spike before, once from seducing him and another letting himself be pinned. But this time, he wanted to do something a little different. When he conveyed to Prima that he wanted to use his spike this time, he expected him to be dismissive. He was surprised to learn Prima had no qualms against it. They met after daily drama between the other Primes settled down, and he didn’t hesitate to lay back on the couch as Prima commanded. As the leader, Thirteen also expected him to be in charge and it stuck.

Prima crawled over him and leaned to graze his lips against Thirteen’s. “Ready for me?”

“Yessir,” said Thirteen rather quickly.

His servos were suddenly pinned by Prima’s and he watched the mech sit upright to align a silver mesh valve with pretty white bio lights radiate over his spike tip.

“Thirteen, just relax and let me take care of everything.”

Thirteen’s chest heaved as Prima sank onto him. The valve took him in completely and suffocated him with a flushed expression from his mentor. Then Prima lifted up and sank back down at a slow pace. The valve made his spike warm and slick. He watched it rise and fall on him with Prima letting go of his wrists and instead displaying himself perfectly. Thirteen looked up at his mentor in awe.

Prima twisted his hips down in an expert motion that made Thirteen buck up. His mentor leaned back with one servo on his thigh for support and the other on his abdomen. Thirteen made a brief noise when the larger mech started going down faster on him. He could only palm the mech’s lower thighs while his spike was being bombarded.

“Feels good, doesn’t it?” Prima panted, “It certainly is perfect for me.”

The red and blue mech couldn’t do much in his position and just marveled at the ferocity of Prima’s determination. He bit his lip and threw his helm back as a sticky mess was starting to form between them. Each time the valve went up, he had seen strands of lubricant attached to him and the valve only to be coated with more back down. His chassis was jolting a little each thrust onto him. A range of contentment and lust rolled off him in the hard motions.

The drowning nature of his system’s heat made him lay there like dead weight as his overload built up. Prima was riding him faster with his engine and vents roaring. Thirteen’s vents were stuttering. The couch sounded like it was close to breaking.

Thirteen grunted and cried out clutching Prima’s hips in a hard overload while the latter panted and chased his upcoming orgasm. He switched to hold Thirteen’s servos down again and down at a new angle that drew out his pleasure. Thirteen never saw Prima arch and gasp upon finishing, calling out his name so forcefully. It changed Thirteen’s perspective on his mentor. Processing this emotion among the cooldown, he loved Prima and the amazing interface they had.

“You were excellent,” Prima said as he got off of him.

Thirteen stared at the glob of mixed fluids leaving Prima’s valve and sinking onto his spike upon departure and groaned at the sight. He wasn’t satisfied. He wanted Prima to be back on his spike and being fragged by him hard. He liked seeing the mech use his nice valve and ride him. Grabbing Prima’s hips, he made the other mech pause and meet his determined optics.

“Please, Prima, do it again. I want...this”

Prima grinned and reached down to widen his leaking valve for Thirteen’s arousal. “You like my valve so much?”

“Y-Yes, sir...please! I just need it! One more time...”

He moaned as the Prima grabbed his spike and teased his entrance again, purposefully making the tip barely press in before being left to rub against the folds. The death grip on the other’s hips made Prima just laugh and quickly grab his servos to hold them steady but humped his length before finally seating himself again. This time, Thirteen tried to assist but had his servos gripped to not interfere. Prima was back in control.

It was pure heaven to him feeling his spike being beaten by the valve that consumed it. Prima rode him hard where he believed his pelvis would soon break, but it would be worth it seeing the Prime leader taking him entirely and watching his spike disappear over and over again in the addiction.

“Thirteen...oh frag yes! You don’t disappoint, ah oh! Frag me! That’s it!”

It was technically Thirteen being fragged hard. He still couldn’t match Prima’s demanding power in their interface. He was just useless and loving being used. He wouldn’t even mind if Prima only used his valve for now on. All he knew in his horny mind was that Prima felt so good. The couch still sounded like it was about to give out.

Notes:

Prima is a slut and we all know it. He wants to get away from his job so bad, he'll take anything. Thirteen's really just kind of there enjoying his spike being fucked.

Chapter 11: LiegeMega - Hate Sex

Summary:

When you don't like your partner, it's not going to be a fun time.

"Easy, you big oaf!"

Megatronus fumed but Liege didn't back down from his statement to make him angry on purpose. To him, Megatronus was a few power cells short of being considered an animal. As he clung to his chestplate peering down and watching the large spike slip in and out of his used valve, he growled at the mech despising him more and more, but that's why it was also so fun to manipulate him into giving him interface like never before. He could tolerate pain and trick the dumb brute for it just the same.

"You wanted me to frag you," Megatronus hissed.

Liege just bit back, "Well, you're good for something this way."

He heard Megatronus snarl like a dangerous predator. Still an animal to him. A small smile played on Liege's faceplates. Claws dug into his back trying to make him bleed. He knew Megatronus couldn't resist a good valve to take. It's what made their little playdates so humorous to him. They could hate each other all they wanted, but animals will hump anything warm to survive.

As soon as Megatronus slammed into him a few more times and he felt the rush of transfluid taint his interior, he was shoved away and leaned back on the berth amused. There was no expecting an underdeveloped beast like the larger Prime to care about anyone's pleasure other than his own. Liege expected no comfort and just trailed visually Megatronus' leave, not a single word more. Good thing was he didn't need Megatronus' help in finishing.

His leaking valve filled with his hateful partner's fluid was quickly stuffed with digits. For a creature of rage and ill-thought manners, Megatronus was a good pet. He didn't mind if the other Prime just used him and left. Liege had the last laugh overall. He huffed and roughly stroked his folds feeling the transfluid trying to escape. He came hard and sent splatters of his overload on the berth. Some made it to the ground as he collapsed with a groan and stroked out the remainder of his charge.

But this wouldn't be the last of their encounters. No, Megatronus seemed quite fond in using him. The feeling was very mutual. He would spit insults to make the large Prime hit his most sensitive spot hard. Occasionally, there was blood. He could hear the animal breathing down his neck trying to make him bleed on purpose. But that powerful spike of Megatronus' was worth all the pain.

As he leaned forward with his servos on a table, he let Megatronus take him from behind. It was hard, slightly uncomfortable, but he was so used to it. It didn't faze him.

"You know something, Liege, you are pathetic."

Liege had closed his optics for a moment but they flew open upon hearing that. His servos tensed at such disrespect. "Pathetic? And this is, umph, coming from the bot who can't help but stick his spike into everything that moves?"

His helm was suddenly slammed forward and pinned to the table. The spike was going at a brutal pace, little pleasure was found in such violence and dark anger. Megatronus made sure he took every foot to the hilt. If he wasn't bleeding before, he certainly was now. The stinging made him grimace and whine. His valve walls were stretched and sore from the quick movements that he wasn't prepped for.

Megatronus growled in his audial receptor, "You use me all the time like a mule, slaving away to satisfy your greedy body. No, you are pathetic because you need me and pretend that you call the shots when you are just a sniveling, pompous snake. I could break you right now. It would be quite amusing watching you be fragged to death just like you seem to enjoy. Personally, I despise everything about you, and you should suffer."

Liege noted that with internal malice as his valve was slammed into. Tears pricked at the edges of his optics from the black and orange mech prioritizing finishing over comfort. Liege clawed at the table when he was harshly filled and the spike ripped out of him with lubricant mixed with blood. He didn't look back at Megatronus. He wasn't laughing this time.

"Next time, I'll rip your gestation chamber out and turn it into a toy for me to use in front of you."

The threat was alarming to say the least, but Liege slowly twisted around to sit in agony on the floor, bumping something off the table that shattered in the process. He barely saw Megatronus' expression in heavy temperament. The anger could be felt from miles away. Liege found it wise to not provoke him any further and made hard breaths trying to process the damage.

That was different. Normally, it was a hard frag with some boundaries. Megatronus ignored all of them to physically tear him on purpose. He finally peered in the direction of the other's disappearance and glared. His red optics constricted with a low rumble. That two-bit beast would pay dearly. They hated each other but now, Liege loathed him more. It was fun at first but the other Prime needed to learn his place. He would make sure Megatronus knew where he was meant to be: in a cage like all the other monsters.

Notes:

Probably would only be hate sex between these two. I can't imagine them liking each other much.

Chapter 12: VectorAlpha - Erotica

Summary:

Never know what you may find in a library.

Vector found something interesting on a visit to the Archives. Every piece of information, every written story, and every fact could be found in its vast library that grew every day, but what he didn’t expect was a story written by an unknown author that had quite the obscene descriptions of two lovers. He thought the title Eclipsed was about astronomy or a research document of how Cybertron got said moons, not what two fictional characters did under the moons. He showed it to Alpha Trion when the Archives were shut down from the public for reorganization. He was helping Alpha with that when he found the novel, and they both looked over it at one of the tables in the main section of the Archives confused until they got to some very obscene details that made both of them grow stunned with Vector having a slightly better sense of humor about it.

Alpha Trion hissed, “This does not belong in a library!”

“You have the open-submission policy. Did you not read what you accepted to be donated to the Archives or did you just go by their word that it was something knowledgeable?” Vector asked. “So, someone lied and falsified this because it’s labeled as ‘cyberbiology.’”

Seeing Alpha really want to strangle him for being wrong was amusing to say the least but as he skimmed to another part with glossas going to where they were supposed to, he understood they were still in a love-hate relationship ever since he first got kicked out of the library.

“It describes the biology of interface between a species in explicit detail and mating habits...so it’s not off from what animal biology covers too, how they mate and function regarding it. Technically, it’s legal. Read it aloud and tell me it’s not cyberbiology. Here, I’ll read it.”

Alpha just glared at him as Vector took the data pad back and began, “‘The versatile glossa played with the folds of her Mistress, digits pushing them apart to let it edge her opening and plunging in. The valve lights glowed as bright as the overlapping moons above. The desperate servant reached back while tending to her lover and pushed three digits inside her own valve...’”

Seeing Alpha staring off to the side imagining it made him smirk. He too was envisioning it as he read on and felt a lingering response on his interface array. At first, he only imagined himself watching it but then he started placing himself into it, and his vents got heavy with dense air pushing through. He could tell Alpha was trying so hard not to do the same. He had to pause partially through to address the tension in both panels.

The more Vector read, the more his panels were screaming at him to take care of itch he was making for himself. Against Alpha’s wishes, he let his valve out just to spite him. The death glare was instantaneous.

“What are you doing?!”

“I’m following the novel’s instructions,” Vector grinned. “You’re just as horny, admit it.”

He began mirroring the sequence of events he read out starting back with the character tasting her partner’s valve and stuck three digits into his aroused valve silently. He knew Alpha was not pleased at all but was blushing just as bad as he was. Vector moved to face Alpha just as another blow to the other’s ego, showing off his valve leaking from between his pumping digits. He saw in the corner of his optic the maroon and purple mech watching him.

“‘She pounded her digits frantically sending lubricant trickling down her servo and thighs. The Mistress arched from the suckling on her valve with the servant’s mouth covered in sweet honey.’”

Alpha Trion scowled before suddenly saying, “I can’t take this. Do not say anything to Amalgamous after this.”

Vector was surprised to see Alpha drop off his seat and shove his digits away. He froze up when Alpha Trion’s glossa instead dove in and aggressively started eating away at him. He lurched forward at the glossa and mouth smothering his valve, dropping the data pad and clinging to the table and chair with a death grip. He eventually leaned back in his seat and sank a little with his legs wide open to accommodate Alpha’s rough treatment. Then he saw Alpha reach back with one servo to caress then pound at his own valve exactly like the novel described. Vector arched from one strong ripple with Alpha’s unoccupied servo forcing his valve lips wider.

There was only a slight pause in Alpha’s feeding when he asked, “Are you not going to continue, Vector? I would love to hear more.”

The timekeeper struggled to get the data pad and between the pleasure he was receiving, he tried his hardest to find where he left off. “‘The-The Mistress gripped her helm tight to keep, umph, to keep her faceplates glued to her valve while she bucked feverishly to grind against the invading glossa-’”

Vector gripped the back of Alpha’s helm and made him unable to back away. Taking the novel’s advice, he grinded his valve against the servicing glossa. The result was blinding bliss and he tilted his helm back with wanton noises escaping his vocals. Ironically, as he looked up, the skylight of the Archives had both moons in view. The master of time and space being orally fragged by a servant of Primus under the two moons...

He tried to read again. “‘Digits were s-shoved in the midst of the glossa’s entanglement with the m-mesh folds, pressing in hard and’-AH?! Oh, Alpha, please!”

The Head Archivist pushed unoccupied digits deep within Vector’s entrance pumping them alongside the greedy licks making him quiver. He bucked from the heavy rise of heat and all but rocked into the mech’s faceplates desperately wanting his close orgasm to spill over. He threw the tablet somewhere on the table and clenched Alpha’s helm horns while the latter was finger fucking his own valve and leaving a puddle of lubricant on the floor.

With a sudden spasm and arch, Vector came over his rival’s faceplates and moved fast against the digits pressed to the knuckle ridges. Alpha Trion sat up watching him be reduced to a mess on the chair but panted while riding his own digits. Vector saw him humping his servo and grinned at the latter’s impatience. A following groan and clenched thighs alerted Vector of his overload. He winced a little at the digits simultaneously removing from both his valve and his rival’s.

“I think I know what I’m reading for the next couple of days because that was only one part of it,” Vector said. But before he could reach it, Alpha grabbed it despite his servos still sticky from their mutual pleasure.

Alpha Trion sneered, “If you want to read the rest of it, it’s going to be in my office because in my opinion, this is still not meant to be in the Archives.”

The silver, gold, and maroon mech shook his head. “I disagree. Biological. We can spend all day arguing right or wrong, but we used the methods in it and got us off. Therefore, they were instructional, knowledgeable, and also biological.”

He could practically hear in inner cursing of his rival’s mind and the glare was still very prominent. But he did want to read the rest of it so if it took a few more visits here to do it and some demonstrations of his point, he could tolerate Alpha Trion’s presence easily.

Notes:

There has to be erotica on Cybertron in some form. I refuse to believe there isn't.

Chapter 13: MicroSolus - Sthenolagnia

Summary:

Amazon chaser? Where's my Prime chasers?

“Please, show me.”

Micronus gave Solus puppy optics looking up at her. He barely stood low-thigh length but instead of using his energy to form a shield and float up to meet her, he took advantage of his cuteness, as he found out Solus believed him to be, and gave her the most innocent look he could manage. Admittedly, he also had an excellent view up her curvy, muscular chassis too. She simply raised a brow with her servos on her hips and stood menacingly neutral. He had hearts in his optics.

“Alright, Micronus, I’ll appease your curiosity.”

“Yes!”

He trailed after her to the storage rooms of the Primes’ tower and sat on the nearest platform while she grabbed solid cyberium metal from the supply closet. She held up before placing it to balance on her upper arm. Micronus had his elbows on his crossed legs and his servos holding his chin eagerly. He watched her play with the cylinder of metal by rolling it on the panels covering her bicep pumps before suddenly curling her arm to an acute angle and putting power into crushing it. The sound of it would have made him wince had he not been so focused on it.

Just seeing her press the cylinder to nearly a flattened shape stirred a lot of things at once for him. Her muscular physique made him realize she could very well break him in half...and he would thank her. She made a prideful, dark expression with a deadly smile as she crushed two cylinders on one arm, and he was in awe. The hard grip her servo was in as a fist looked like it could squish his own arm in one go or...

Micronus felt a flare of arousal run through him that made him shiver visibly for a second, then the warmth fled to his cheek plates biting his lips with half-lidded optics.

“Amazing...can you do both arms at once?”

Solus obliged him and balanced two cylinders on one and them held the other two before skillfully throwing them up and catching them with her unoccupied arm. At the same time, Micronus brought out his spike and slowly stroked it seeing her crushing four metal pieces at once and flexing her chest plates with a heroic and powerful pose. He was enamored, especially as she looked him dead in the optic a little deadpan to his obvious obscenity but not peeved or disgusted. She tossed away the broken metal and simply leaned against the platform on her left looking at his spike.

Solus tisked, “You really are shameless, aren’t you?”

Micronus looked at her dreamily and touched her left bicep panel. He felt up the contours of its design and nuzzled it to Solus’ humor. Then he purred, “You can bench press me any day, baby, even if it kills me.”

“I can do something better,” she offered.

Micronus looked down her exquisite body but grew confused as she moved away. Solus grabbed a couple large cubes of Energon from their power vault and placed them beside her as she sat across from him. Micronus sped up looking at her legs spread wide until she settled a cube between her thighs and opened her valve. She held it steady with said thighs and put her servos back on her platform to show off not needing them. He didn’t know what she intended to do until Solus began squeezing her legs together with the Energon cube trapped.

Every part of his system was on hyperdrive and he automatically was pumping himself staring mouth open at the sight of Solus making the Energon cube start to crack and drip out its contents. He wasn’t prepared for the explosion. The dense cube busted with a laugh from Solus as it coated her inner legs, abdomen, and left small streaks on her chest and faceplates. The range outward only reached below him right before his platform. Her valve was bright blue with Energon flowing down and dripping off it.

Solus shocked him with the display of strength and when she looked at him with a proud, licentious expression, he came right there. What he wouldn’t do to taste the Energon on that valve at the risk of making her overload and possibly having his helm popped if she accidentally squeezed him in her pleasure. It would be worth it.

But then her brows furrowed, “Micronus, your noseplate is bleeding.”

The Prime Minicon still didn’t look away from her though he felt blood trickling down from his nasal vents. In his post-overload haze, he said, “Oh no...it’s-its fine. It’s just a nosebleed. I’m just admiring the goods...”

Solus grinned, “Yeah? Admire this.”

She placed two of the hard cubes stacked between her thighs and grunted as she squeezed them tight again. Micronus had his jaw loose barely flinching as she managed to shatter both.

“...May I please sit on your lap?”

Solus didn’t seem to mind the request and he was on her faster than a turbofox. He got touchy with her thighs with hypnotic obsession admiring what they could do. At one point, he begged her to let him hump her leg which she agreed simply because he knew she was amused by his dedication. While he grinded his spike against her thigh, she drank the last cube of Energon before crushing its empty box with both servos. That helped him get off quicker. He ejaculated on her thigh with a groan.

“Did you enjoy the show?” Solus mused.

Micronus mewled, “I’d do anything for you to break everything in this room by crushing it...”

“Hmm, well, I can’t do that because we’d get into trouble, but I could crush you.”

Her faux soft blue optics made him sit up drunk on his pleasure and scoot closer to lean on the divot of the space between her lower chestplate looking directly up at her like she was a goddess. “I’d-I’d do anything for that...”

Solus gave a sultry smile of deception. He didn’t care what she planned on doing as long as it was with her. She ended up pinning him with her chassis laying on him. His faceplates were still among her chest and he mapped her tense abdomen as she grinded down her valve on his spike. He didn’t care that he was at her mercy. Being trapped between the platform and her strong frame was heavenly.

Notes:

I think Micronus would have a kink for strength and size which makes the pairings of him with Solus and Onyx plausible. And who's to blame him?

Chapter 14: Mega13 - Clothed Sex

Summary:

Megatronus likes what Thirteen has on a little too much.

Megatronus had to look at what the weird blue material was. He felt it. The texture was strange, definitely not any metal he knew of. “And where did you find this?”

Thirteen held up the fabric that looked like a jumbled mess with gold chains at the moment with glee. “Prima just got done negotiating with the Dargonians in the Kalmora Sector. They gave him a transport full of this stuff as part of their peace treaty. They call it ‘clothes.’ While we are covered in armor to protect our vitals and protoform molds, they wear these instead in their form of decency. This particular fabric is reventium silk from their reventor weaver worms. Cool, huh?”

“So, like how we have panels that protect our reproductive equipment. They have theirs on the outside and this...covers it?”

“Yes, also makes for fashion statements if I understood correctly. They are around our size so this might fit me. I’m going to try it on.”

The black and orange mech didn’t argue and leaned against a wall waiting patiently for Thirteen to show him what was so special about so-called clothing. To his surprise, the Prime came out wearing an open V crop blouse connected to shoulder cloths and gold chains that attached to the sides and to cuffs on the upper arms and wrists. The maxi dress-like cloth attached by a gold low waist girdle flowed down to his ankles and had a loincloth of a beautiful pattern over it. The slits that allowed his legs to move freely had three gold chains across the gaps near the hip area. It emphasized Thirteen’s chassis a little too much...

“So, what do you think?”

“It’s interesting. Very...shapely. And they have no protective gear whatsoever for any vitals?”

Thirteen shrugged and leaned forward to bend on a platform pushing aside the rear section of the dress exposing his aft that had some type of material piece that ran between his legs covering the outline of his exposed valve. “They...They have this and it feels so weird. It keeps trying to ride up too. That’s the only thing I don’t like about it. I don’t know how beings find this comfortable.”

Megatronus had a completely different opinion staring at the clothing. He had an appeal to the form-fitting material now that he had a better understanding of it but the main thing that was getting him was how it made everything easy to access.

He stood up and lightly lifted up the rear section of the dress cloth from Thirteen’s grip with a hum before eyeing the poorly covered valve. He reached to place a digit between the cloth and his aft noting how easy it could also be broken if he tried. Thirteen looked back at him stunned at his touching until Megatronus coiled the fabric of the undergarment around his digit and tugged slightly to make it ride up tight between the pretty mesh folds.

“Well, I certainly like it,” Megatronus remarked amused.

He tugged repeatedly and watched Thirteen try to buck against the thin fabric antagonizing his valve. The larger Prime let it go and settle back on him, then retrieved his spike and steadily rubbed it against his clothed aft. He grinned hearing Thirteen gasp when his spike dipped to instead rub along the outline of his valve unable to breach with the cloth in the way. It didn’t stop him from humping him.

“Maybe the Dargonians have the right idea after all. They know how to make nice clothing that really makes your form pop.”

Leaning against Thirteen’s backside, he continued to thrust across the partially exposed valve feeling it getting wet and needy. The fabric was becoming wet too adding a new texture to it he liked.

“Megatronus, please,” Thirteen whimpered and pressed back.

“What do you want?”

“Just stop being a tease and rip it off already.”

Megatronus chuckled, “Who said anything about ripping it?”

His claws pushed the undergarment to the side of the valve and grabbed his hips to steady Thirteen from impaling himself too soon so he could align right. His tip found the entrance and thrust in. Intertwining his digits with the chains on the hip, he let the dress cloth fall back into place to barely cover their obscenity. Thirteen clung to the platform with his audial fins pointed back and each pounding of the spike made the gold decorative chains rattle against his armor.

Megatronus growled possessively hearing him respond well to his attention. His spike was suffocated in tight heat and some of the fabric felt nice sliding against him. He panted like an animal slamming deep inside and focusing only on Thirteen and the way the clothing moved in his rut.

An overload hit and Thirteen whined pawing back at his valve. But Megatronus was far from done and flipped him over to find the front view of the clothing just as appealing. He flicked aside the front piece and loincloth to see the outline of Thirteen’s spike hard against the fabric still unreleased. But the valve was just his target of desire with its left side covered and moist by the undergarment trying to form back in the excessive movement. He held Thirteen’s inner thighs wide open and shoved back into the red and blue mech.

He all but snarled darkly, “I hope you plan on showing me what else our new allies brought because I’m going to frag you in each and every piece you wear.”

“Y-Yes, ah ah, frag!”

Thirteen had one servo over his helm and the other on his chest between the disheveled open blouse. The fabric scrunched nicely along the top and bottom of the girdle. Megatronus leaned down to bite at his neck and swiped his glossa over the center of his collar armor.

Even though he was skeptical at first, Megatronus now adored the fabric and its purpose, especially how it looked on Thirteen. Whichever future clothing he liked the least, he would tear it off Thirteen and play into his darker fantasies but for now, he aimed to enjoy the unusual display as much as he could.

Notes:

I made an excuse to give robots clothes to fuck in. Don't @ me. You knew this was coming.

Chapter 15: AlchemOnyx - Assistance

Summary:

Alchemist helps the big brute satisfy himself.

Alchemist had Onyx, Nexus, and Liege at his bar. The beastformer sat on his rear with his front legs upright against the counter wall since he couldn’t sit on a stool like everyone else. Alchemist slid him a mug of high grade with Energon preservatives only found and harvested fresh from the Mithril Sea Underground. The other two were talking up a storm on the opposite end of Alchemist and Onyx drunk. So, they kept each other company instead.

“Credit for your thoughts?” Alchemist asked, trying to find something good for Onyx to talk about.

Onyx somewhat smirked with the optics on his forehead closed while his regular looked over his drink. His baritone deeply muttered, “You don’t want to know.”

“Try me. We all live in the same tower; what could it possibly be?”

He saw the larger mech look between him and the two other Primes chatting away before the latter sighed, “I’m...having trouble with my spike.”

Alchemist leaned close on the counter and gestured with a low tone, “Quintus is a medic-”

“Not like that. I just haven’t been satisfied with any self-service lately. Nothing I’ve tried has been working and I really need something. I’ve used my valve multiple times, fine, easy to satisfy, you know. But I’m in the mood for my spike and I guess I need more physical than visual with that.”

There was some mental debate in Alchemist’s mind whether or not he should help Onyx like that. But then again, half the Primes weren’t very secret when drunk about who they slept with. He suddenly whistled at Nexus and Liege.

“Bar’s closed, boys. I need to help Onyx with something.” He heard them groan but obey knowing he didn’t take kindly to stubbornness. After they left, Alchemist locked the door and gestured to Onyx. “Lay down and release your spike.”

Onyx swallowed a sip of his drink and mumbled, “What?”

“Go on, you heard me.”

Onyx blinked dumbfounded awaking his second pair of optics before slowly moving to an open spot on the floor and sitting on all fours. He tipped over to roll on his backside uncertain. His legs all bent close to his chassis and tail sliding sluggishly against the floor. He rested his servos overlapping each other on his abdomen politely. Alchemist watched him present his spike and then straddled him right behind it. Onyx’s helm plates twitched considerably.

The heavy-set Prime gave a small lick to the tip of Onyx's long spike. He kept his optics on the small flexes of the ankles of the powerful hooves, not wanting to accidentally get kicked. His glossa kept running over the tip to entice the beastformer who at first wasn’t very responsive but upon watching him hold the spike and service it, there has a hint of arousal growing. In time with his glossa’s attention, Alchemist started to pump the length slowly. Another jump of pleasure seemed to arise in Onyx.

“There wasn’t anything wrong with your spike, Onyx. You just haven’t had some decent company in a while. Jacking yourself off only goes so far,” he mused.

Alchemist stuck the spike tip in his mouth and tried to take some of it in to prepare him. At the same time, he immediately opened his valve and sank two digits in to occupy himself. Onyx stretched his legs uneasily at his focus on the spike. He took it out of his mouth and continued pumping it simultaneously with himself. Onyx was grunted and covered his optics unable to thrust up or turn with Alchemist pinning his rear end.

“Alchemist, you son of a-damn it! D-Do more, I beg of you!”

Well, he was a kind mech after all. Alchemist stood up and pressed the tip to his entrance devilishly. He forced himself down on it at his leisure, crouching to hold half and slowly rose up and down on the length stretching him wide. He grabbed Onyx’s front legs flexing in response to him and held them still. Onyx had all four optics closed with a purr and his fanged dentae tight together. Alchemist thrust himself down still unable to take all of him yet. The spike hit the far space of his gestation chamber walls and pressed against every node he had.

Onyx was overwhelmed and released inside of him bellowing and clawing at the ground. Alchemist was driven over just by the assault on his interior. But despite the transfluid squeezing past the tight fit, Alchemist continued to press himself onto the length with heavy moans.

The beastformer was large for most bots but Alchemist was driven to take it all. He was so close to hitting the base of Onyx’s spike despite the heavy strain it put on his valve. He stopped his motions to readjust and sink all the way. Onyx panted, chest and lower chassis heaving wanting so bad to ram him as typical animal instincts. No, Alchemist was in charge now. The overabundance of spike made him no longer able to frag himself properly on it.

Instead, he resorted to grinding against the base that made the centaur widen and flex his rear legs kicking air. Alchemist clutched the front hooves hard jolt his hips forward hard. His exterior node and valve folds rubbed on the ridged underbelly of the beast covering it in their mixed fluids.

“Onyx!”

The other Prime was relying on his animal-like noises now. There wasn’t a single intelligible thing he said as he was rode on. Alchemist made several strong thrusts before he was forced to come. Onyx tried to lift his rear with his upper half to curl up injecting Alchemist with every drop of transfluid he had. The beast groaned defeated.

Alchemist had to bend forward and register how deep Onyx was and how to remove himself safely from the whole length. He all but joked out loud, “Next round of drinks are on me now that you seem to have your mojo back, big guy.”

It was a process getting off Onyx, one that left him sore but not regretful. Fluid was everywhere and his abdomen felt fuller than when he outdrank Megatronus once...and that mech could drink. Still, as Onyx rolled to lay partially on his side with a forced, post-pleasure smile, Alchemist didn’t care he got one of his seats wet as he crashed onto the bar stool sedated. At least, he managed to help out a friend if anything...

Notes:

As much as I love using Onyx's valve, he needs some spike action too, but I know he would be too prideful to admit to a medic he needed help getting back in gear...so why not the friendly bartender? Alchemist needs some spike.

Chapter 16: NexusQuin - Tentacle Sex

Summary:

Nexus convinces Quintus to get a little freaky with his extra limbs.

Nexus looked at the versatile tentacles as they grabbed things through Quintus’ hooped winglets without the mech having to look at the objects. There were four main tentacles and six smaller ones that didn’t leave their engraved slots designed across his back. The big four had slots to wrap around the waist instead. Each slot was like a pattern etched out of Quintus’ form that only revealed the tentacles following those grooves when necessary. It was mesmerizing to see them act like limbs, coiling and pulsing with purple bio lights across the slim armor they possessed. One of them currently wrapped around Quintus’ pointed collar armor that stuck up to hide his lower face at certain angles. The kibble of the green mech made him look like a chancellor with tailcoat armor attached to his hips down. The tentacles just added to a more alien appearance than normal.

“Nexus, stop gawking,” the slim mech sneered, his purple optics narrowing.

The larger mech replied getting up from his seat, “Just admiring a few details-”

“You think you’re the first bot who's had the thought of me using my appendages for other things? I see that look and no, you are not going to test it.”

“Quintus, babe,” the blue and red mech pleaded calmly, “I am the epitome of testing. I can depart into five different bots. I love the bizarre and mundane.”

“If it gets you off, it also gets you quiet afterwards I suppose.” Quintus approached him and only came up to his lower chest. Then Nexus started feeling the tentacles creeping up his waist and across his hip down to his thighs. Quintus barely moved with his arms crossed looking up at him. “Can I make the great Nexus Prime scream like a pleasure bot?”

The large tentacle mapping his thigh dipped to slither across his panel and made him peer down with a stifled noise when he realized they had the ability to secrete a type of slime that left trails over his lower frame. Quintus was eyeing his slow descent into madness feeling each appendage creep along sensitive areas and even across vents. Then the thin mech began to circle him, dragging the tentacles with him to move around getting into trouble everywhere they could. Nexus bit his lip with his red optics twitching.

“See, this is the most humorous thing to me. You talk a big game half the time but really you just want the next big thrill to satisfy that superiority complex of yours. It’s quite entertaining to see you cave to your deepest, darkest fantasies just to draw attention to yourself. You like the spotlight, don’t you, Nexus?”

One of the tentacles started nudging around his interface looking for a way in. He squirmed from the one around his hips going to his aft as well. Quintus came back around to be in front of him and reached up to gracefully hold the underside of his chin.

“Hmm, you would look a lot better begging on the ground at my pedes.”

Reluctantly, Nexus lowered to his knees and waited until Quintus lightly tapped his interface with the tip of his pede and a raised brow. He took a few breaths through his heated vents and obeyed...only to gasp and whine as the tentacles slipped over his valve folds and wrapped around his spike. The slime they emitted toiled with his sensors and slickened his equipment.

“Quintus, I didn’t know they could do that,” he muttered.

The smaller mech hummed, “There’s a lot of things you don’t know about me. But since you’re so curious...”

The thicker tentacle scoping his valve suddenly plunged into him and rode up his interior walls pulsing. Nexus held back a moan feeling the appendage inside him move about while the others wrapped around his limbs to keep them secure. Quintus laughed low and settled on his lap, brushing his open valve on the side of his spike being seduced by a small tentacle circling it length.

Nexus couldn’t grab Quintus to make him take his spike like he wanted, and the tentacle in his valve was joined by a secondary that prodded him in unison. He groaned and sank farther down to use the floor to press the tentacles deeper into him. Quintus just kept teasing him as he looked at the smaller mech with hazy optics.

Finally, Quintus granted him a little mercy and seated himself on his spike. Their bodies melted together with a deep kiss. When Quintus started rocking, the two thick tentacles inside him grew unnerved and more active reacting to their master’s lust. Nexus was still restrained only able to try and get the tentacles pumping into him.

His movements down on them contributed to grinding up on Quintus who used not just his valve but his appendages as well. One went around Nexus’ spike and followed it into Quintus adding pleasure to both of them.

The slimy tentacles tensed alongside Quintus, causing Nexus to shout and frag himself on them with an overload ripping through him. Quintus followed with a strangled cry before muffling it with a sloppy kiss. Nexus barely noticed the appendages wrapped around his arms subsided, he just jolted when the tentacles in his valve slipped out leaving an utter mess in their wake.

“Oh, Primus,” he cursed. “Oh, please tell me they can combine.”

Quintus mused, “Technically, I can make them connect to one another briefly. Do you want that valve of yours filled?”

Nexus had a fluttered grin and purred, “I can take anything. It’s me, remember?”

Notes:

Nexus would be one of the more daring I believe. His nature would be demanding but willing to be on either end of the relationship as long as he got something good in return. And Quintus would use those tentacles of his for good times without a doubt.

Chapter 17: ZetaMega - Muzzle

Summary:

When your partner can't stop biting, there's ways to deal with that.

“Quit biting,” Zeta warned.

He saw over his shoulder as he was currently being stuffed by a spike a fanged smile with pronounced front canines amid an otherwise flat set of dentae. The mark on his neck was bleeding already and he gave an exaggerated sigh. One thing he hated about Megatronus’ habits was the biting during interface he developed. He reached behind him to grab one of Megatronus’ horns to push the helm away creeping back close to try and lick the wounds.

He finally decreed, “If you don’t stop, I will make you, and you won’t like it.”

Megatronus sneered, “As if you could.”

Zeta took that as a challenge and kept that in mind the entire rest of their session. But as soon as Megatronus was called away, he went to find something that would truly stop him from biting in the future. He didn’t like explaining to others how there were huge bite marks on his person to begin with. It was an annoyance, but Megatronus would learn.

Gathering himself, he went out secretly to a pet store in downtown Iacon that had cyber-dogs, cyber-cats, cryo-condors, and more along with collars and one particular item he sought. He grabbed the largest in sight that was only big enough for possibly a motormoose and held it up for the associate to see.

“Is this the biggest one you’ve got? I have a...creature bigger than our common Cybertronians, needs a little training. Something that can also wrap around horns. It’s a monster.”

“I’ll see what I have in storage,” the mech replied without batting an optic.

Zeta smirked and waited until one was presented. He nodded with an evil glint in his optics as he saw it came with an electronic key. “Perfect.”

That evening, Megatronus was taking a nap and Zeta carefully placed the item over his mouth and strapped it around his horns and the back of his helm between the spiny plates. He activated the lock and was content with the results. He waited for Megatronus to wake up and poked at the unusual contraption on his face before shaking angrily like a beast. He tried to use his claws to break it off but saw Zeta and glared.

The teal Prime mused, “Not so fun now, is it?”

Megatronus’ optics were bright, and his voice was slightly muffled by the chrome muzzle he wore. “Zeta, get this contraption off me!”

“Not until you learn not to bite and be good. Now, sit.”

Megatronus reluctantly obeyed with a death stare as Zeta opened his valve panel and started kneading it to get him focused solely on it. The black and orange mech couldn’t stay mad for long as he predicted but there was a heavy disdain for the muzzle when he tried to get close to offer to play with the valve only to bump it with said muzzle. An irritable noise resonated in Megatronus, much to Zeta’s amusement.

Zeta then turned around to hold himself steady on a stand in Megatronus’ berthroom and whistled for Megatronus to get up and stick his spike into him to see how long the mech could resist the urge to attempt to bite again. Megatronus’ chest almost flattened him against the stand, and the spike shoved in peeved. The thrusts told all, an impatient mustang going in for it all with utmost greed.

Sure enough among the hard rut, Zeta felt a bump of the muzzle to his neck and shoulder. “Ah, ah, what did I say?”

Megatronus fumed through grunts and slammed his hips forward to impale Zeta in dominance. The smaller mech knew there wasn’t much he could do about that as his valve was stretched on the large spike. It was revenge for the muzzle surely, but damn did it feel fantastic. The panting over his shoulder sounded like deep guttural huffs with the muzzle on. The grip on his hips was denting for sure.

Each thrust sent lubricant spilling out of him. Zeta found it easier to enjoy being rammed without the distraction of the bites. The muzzle still bumped him occasionally, but it seemed to be from Megatronus leaning into him more in chasing an overload than actually trying to bite him. His inner thighs were stained with lubricant running down while the spike pounded against his farthest node.

Zeta gasped and reached back to grab the muzzle bars and drag Megatronus’ face to rest on his shoulder in comfort. The latter all but forgot his biting habits in the snapping of his hips. Though it seemed there was work to be done in breaking the habit entirely, he liked how easy it was to guide Megatronus.

“You like it.”

“Shut up,” the other mech panted.

Zeta replied, “Only if you make me overload a few more times like this. Be good and I’ll remove the muzzle.”

That sent Megatronus’ pupils constricting to small dots with a feral rumble. Zeta had him hooked with a challenge, something he couldn’t refuse. The muzzle just made it a little easier to coax him into moving faster to get the job done so he could lose the contraption. Zeta figured he was going to deserve a nasty bite afterwards, but it was worth it for the time being.

Notes:

Sorry for the month-long absence, I've been dealing with coming to terms with my condition...and extended it because I also got Donkey Kong Bananza which I wanted to play since I heard about it. It was my way of taking my mind off things too. So, I hope this makes up for it.

Notes:

We doing this, every pairing you can do with fifteen Primes total. Keep in mind Thirteen and Optimus are going to be the same character in this and the personality will be based more on Thirteen. The other two extra Primes will be Zeta and Sentinel. In some universes (Aligned...cough cough), they are the same character...weirdly. The character is Sentinel Zeta Prime and he goes by both names. We aren't doing that, Sentinel and Zeta will be separate. Look forward to updates every other day!
