Work Text:
It was an uneventful return back to the hotel in urban Iacon for Bulkhead.
After a long, busy day of working across town, the newly appointed senior space bridge technician arrived to his lonely, dark hotel room — coming back to nothing but the soft hum of electricity coming from the energon dispensor. With a heavy sigh, the large mech walked into the room, and let the door swing shut behind him. With a flick of his servos, Bulkhead turned on the light switch, and began to make his way to the large, welcoming, cushy hotel bed.
For the umpteenth time that day, Bulkhead found himself bored, lonely, and more than a tinge regretful of the current assignment he'd taken here on Cybertron. While the Bulkhead of days past had always dreamed of doing something just like this for the people of Cybertron for cycles upon cycles, the Bulkhead of today found himself disillusioned and tired of how the Iacon Department of Interstellar and Orbital Transportation up in the high towers liked to push, pull, and play with him — especially since he had Prowl, his expectant conjunx, waiting paitiently for his return back to Earth.
Initially, Bulkhead had been cagey about going on this job on Cybertron because he was afraid of Prowl going into premature emergence while he was gone for a couple of weeks. However, after a checkup with their obstretician, Bulkhead's worries had been soothed enough by the knowledge that their sparkling didn't seem to have any signs of wanting to come out that he'd decided to take the jump to work abroad. He'd also got Prowl's approval to take on the job — with the ninjabot even urging him to get at least some time to himself before their sparkling's emergence. Bumblebee — who lived on the Autobot compound with them — even promised to keep an eye on Prowl's health for him so that he could get his job done. However, Bulkhead still couldn't help but worry about his family back home. Even a galaxy away from his conjunx, sire coding still coursed strongly through his circuits. Even though Prowl spoke to him regularly while he was abroad, Bulkhead still found his spark yearning for its bondmate.
Reaching a servo towards the bedside table, Bulkhead pulled his laptop off the surface and plopped it in the crook of his arm. He languidly opened the laptop — quickly entering his PIN into the login prompt, and being greeted with the sight of a notification. Upon clicking on his instant messaging app's inbox, Bulkhead was greeted with a short message from his conjunx Prowl.
'DO NOT OPEN THE ATTACHMENT IN PUBLIC. Enjoy your surprise in private please. Much warmth, Prowl ;)'
Bulkhead quirked an optic ridge at the message, but still clicked on the attached video file to download it to his laptop. Once the video had been downloaded and initalized on his computer, Bulkhead got off the bed, and scurried off to lock the hotel door. Anticipation fluttered its way into his tanks — if it necessitated a whole video, Prowl's surprise had to be something exciting. Bulkhead settled back in his bed, and promptly pressed play on the video.
The video opened unceremoniously. Grumbling something under his breath about shared memory cards, Prowl looked bashful as he set up the camera. A faint blush was spread across his dark face plate, accompanied by the gentle, yet ginger look in his sea glass optics. As Prowl tried to get the camera to focus on him, a clawed servo clutched and held his gravid mound of a belly — carefully holding it out of his way.
"Hi, Bulkhead." Prowl greeted. The creaking of springs from inside the mattress could be heard as Prowl leaned back away from the camera and sat down with his knees crossed. "I hope you're having a safe trip and that work is going well for you. I just wanted to, uh, send you this to remind you that I'm thinking about you."
Bulkhead then watched with wary eyes as Prowl got up to crawl and reach for something off frame. What Bulkhead wasn't prepared for, though, was when he saw Prowl come back into frame holding what looked like a bottle of lube, a needle less syringe, a dildo, and a sterile collection cup. Bulkhead's optics widened as he recognized the cup as one of the containers that Prowl's obstetrician made him fill with transfluid before he took off on his weeks long trip. Upon recognition, the big bot immediately sprang to pause the video so he could take a cursorary look towards the window of his hotel room. Upon realizing that the blinds were shuttered closed, Bulkhead hesitated for a moment before he unpaused the video.
"Ooof," Prowl sighed as he came back in the frame. He slowly sat back down — smiling almost serenely as one of his hands reached to settle on his pregnant belly. "I'm not as swift and smooth as I used to be — especially not at this size."
Prowl smoothed his hand over his bump, tracing little patterns over the stretched protoform with his palm. He looked stunning like this, Bulkhead thought as he watched the holovid with rapt eyes. Quickly approaching his third trimester, Prowl practically seemed to glow with life. His long, lanky figure had bloomed and blossomed with gentle new curves that accented the shape of his frame. His hips and thighs had grown plump and supple, perfectly primed for carrying Bulkhead's sparklings. Stretch marks crawled across his body, almost resembling lightning strikes across his deep gray protoform.
"This bump of mine makes a lot harder to move around than it used to be." Prowl sighed as he shifted to sit atop a small pile of cushions. As he reclined back, he continued to muse on about his condition. "Being here all alone this late in my carrying cycle just makes me miss your delicate touch. Every day that you're gone, I wish that you were home with me — holding and caring for me."
Before Bulkhead could think much about the cloying words that escaped Prowl's mouth, the ninjabot spread his legs wide apart, and began to stroke his hand along the inside of his thighs, showcasing the stretch marks that trailed across the junction of his thigh and codpiece. He teased his neatly trimmed and filed claws at the edge of his modesty panel, sighing as he then traced his fingers up to his sides.
"I miss all of you, Bulkhead. I miss your large servos and how gentle you handle me…" Prowl then grabbed the bottle of the lube, and with a bit of struggle, stuck a claw tip into the gaps of his codpiece. With a mechanical hiss, Prowl manually released his modesty panel to expose his moist valve. "I miss how good your fingers feel inside of me. I miss your big, heavy spike — how it strains me and stretches me so good."
Prowl let out a sigh as popped open the bottle of lube, and began to slather it on of the lips of his valve. Bulkhead watched as Prowl's delicate fingertips reached for his clit. Gently, he began to massage lube into the nooks and crannies of his engorged valve folds. The ninja bot let out a soft gasp as he began to massage his anterior node in circular motions. Bulkhead found himself stunned — his gaze affixed at the sight of Prowl opening himself up to the camera so vulnerably. He could almost feel the energon rushing down to his panels at the sight of his gravid conjunx yearning for him — left aching for his gentle touch, his whispers of praise, and his girthy, well-endowed cock.
"I hope you, ah, don't mind this silicone substitute I dug out of an old collection of mine. It's nothing special compared to your spike, but it's the biggest toy I could— Unnhhh, find." Prowl breathed out a chortle as he reached over for the dildo and the flask of transfluid. The ninjabot strained to reach his lanky arms over his large pregnant belly, seeming to struggle with manuvering around the bed in his current condition. Once the toy was well within his grasp, Prowl huffed out a sigh of relief before he collapsed on his side. A bashful smile spread across his lips as he began to gingerly stroke his hand along his cushy, soft sides. "Ooofh, I think I need a minute to collect myself before I get to the main event."
Bulkhead found the sight of his conjunx so heavy and gravid with his sparkling — his frame so fertile, fat, and bursting with new life, and his body so completely consumed with the fruits of their love and devotion to one another — to be almost perverse. Before Bulkhead knew it, he found a claw of his subconciously inching towards his codpiece, where his spike strained against the metal front cover.
"I've never done anything like this on camera —in fact, I honestly never took myself as the type who would feel the need to show off like this." Prowl smiled coyly as he grabbed the dildo, and then popped open the jar of Bulkhead's transfluid. For a moment, he dredged the tip of the dildo in the jar, before he gave the base of the toy a squeeze. The mouth of the dildo opened up and began to drink up and absorb the transfluid. "But love really does drive you to do the craziest of things, doesn't it?"
Bulkhead felt his intake run dry as his frame involuntarily released his spike. The sinful, carnal display on Bulkhead's holovid screen almost felt like a form of punishment for daring to leave his needy, pregnant conjunx alone with just a crude, silicone substitute for his cock. Both Bulkhead's spark and spike ached for Prowl — ached for the mech he'd chosen as his mate, his conjunx, and his companion for the rest of their lifecycles. When Prowl revealed that the dildo had completely drained the transfluid collection container, Bulkhead began to stroke his cock. He stroked in time with every movement Prowl made — his blue optics rapt with lust as he watched Prowl drum his fingertips on the shaft of the toy.
Prowl then carefully put down the dildo, and reached up towards the camera to adjust it to angle down between his legs. Prowl grumbled something faintly about how stupid modern tech could be as he tried to adjust the tripod. Too amused to be turned on in the moment, Bulkhead slowed his strokes to a standstill as he watched Prowl furrow his optic ridge in frustration. Once he was confident on the camera angle he'd set up, the ninjabot backed away from the camera, and then sighed.
"Ugh, pardon the interuption. I had to fix the camera. I just needed to show you how much you're missing out there on Cybertron, Bulkhead." Prowl let out a slight chuckle as he leaned back into a pile of pillows sitting at the head of the bed —Bulkhead could slightly recall the pile being set up early on in Prowl's pregnancy to support Prowl's back during recharge. "I miss you so much. I wish you would come in me— I mean, come home to me as soon as possible."
Prowl grabbed the dildo, and then spread his legs wide open. He traced the spike's head against his inner thighs, the junction of his codpiece and legs, and then on the exposed lips of his valve. Prowl sighed as he lifted his hips, and then traced the dildo across his valve — going from his clit down to the entrance of his valve. Slowly, Prowl began to nestle the toy into the plump folds of his pussy. At the sight, the servo Bulkhead had gripped around his cock begin to pump up and down his shaft. The world outside of the holovid on Bulkhead's laptop ceased to exist as the big mech watched Prowl moan in satisfaction as the toy breached his valve entrance.
"Ohhhhh, that's good. Yes, unnnh, Primus— this toy used to be such a big stretch for me, but being your conjunx made me so used to your long, girthy cock." Prowl began to push the toy deeper in to his glistening wet valve. "You've ruined my valve for any other mech, you know. I could never go back to anyone else except for you, Bulkhead. There's nobody else in the galaxy who I want more than you — nobody else who I would trust with my body, spark, and soul."
Bulkhead felt the firey flame of lust start to boil in his struts. As his conjunx began to fuck himself with the dildo, Bulkhead began to stroke his spike in the tune of Prowl's thrusts. The noises of Prowl's gentle moans and groans filled the room, creating a sinful soundtrack for Bulkhead to touch himself to. In the space bridge technician's head, he recalled crystal clear memories of how warm and welcoming Prowl's valve always was for him, how Prowl would guide Bulkhead's claws along the sensitive sides of his chassis, and how Prowl would leave shallow gashes on his back with his clawed servos.
Bulkhead groaned as he began to inch closer and closer to climax. He fantasized about how the greeting Prowl would give him once he came home to Earth — how Prowl would waddle up to him, and pull him into a gentle, yet passionate kiss. He could only imagine how legendary the makeup sex would be. Bulkhead could see it in his head right now — Prowl would lead him to their martial bed, lay down on his side, spread his long, gorgeous legs, and would let Bulkhead rut his spike into his valve. Perhaps if Bulkhead played extra nice, Prowl might let him eat him out after they finished up the transfluid donation. Bulkhead savored the thought of suckling on his conjunx's plush, pregnant pussy.
When Prowl finally overloaded from a combination of rubbing and teasing his clit, and from fucking himself with the dildo, Bulkhead was met with the sight of Prowl moving his servo to squeeze the base of the toy. As globs of pink-tinged transfluid shot up into and around Prowl's valve, Bulkhead sped up the servos pumping his cock. Without a care in the world, the large mech came with a warbling shout — transfluid shooting out in globs and then falling unceremoniously between his big, strong thighs.
In the afterglow, the laptop that sat in the crook of Bulkhead's arm was all but forgotten as its owner had skirted off to the washracks to clean off the transfluid in between his legs. The video continued to play, with Prowl — blissed out and growing pleasantly drowsy — leaving one last message for his beloved.
"Oooh, Bulkhead —" Prowl breathed. "I hope that lets you know how much I can't wait for you to come home to me. I love you so much."
Then, once Prowl shut off the camera, the video feed cut to black.
