Chapter Text
This was definitely not how he thought things would progress. He was not even sure what was happening at this point. There had been a ton of questions and he had agreed to… something? But how did that lead to being pinned face first to a wall being touched more than he thinks he has ever been touched before. His breathing had become irregular the second his chest had hit the wall. His mind muddled beyond recollection at this point. His body is reacting more to the touching than his instruction.
Nightmare, a skeleton much like himself only covered in some kind of black goo and towering over him, had his hands pinned up beside his head with his own, as tentacles explored and moved cloth obstacles as needed. The dark skeleton was very experienced when it came to this kind of thing, keeping control over every aspect. Every micro twitch telling him something of the skeleton he had under him. Even every withheld action was telling in some way.
“I said summon something for me.” Nightmare growled into the small skele’s acoustic meatus, feeling him tense under his hands. “Or I can make something form, is that what you are asking.”
The only answer was a small whimper. Then one of Nightmare’s tentacles rubbed harshly at the trapped skeleton’s ischium causing the latter’s pelvis to buck back against his captor’s pelvis. The gasp that escaped the smaller’s teeth almost seemed surprised by the feeling. Not wanting the skele to think he could escape Nightmare ground his own pubic symphysis into his sacrum earning a sharp inhale.
“Come now, you came to me.” Nightmare tightened his hold on the wrists in his hands. “Let go, it will feel so much better.”
Feel so much better? What would? Nightmare was asking him to do something. He was so unused to being asked to do something more than lying around or answering questions. What was Nightmare expecting of him. This was all overwhelming he couldn’t think straight. Stars, he was making a bad impression. A tentacle in his mouth kept him from voicing any of this.
Suddenly the pool of burning magic in his pelvis snaps into place bringing a sudden relief that built up quickly back to a burning heat. He couldn’t see past the tentacle in his mouth to see what he had manifested around his pelvis. It was a strange sensation against the sensitive bone down there.
“Hmm, that is how you want it then?” Nightmare almost cooed teeth threatening at the left clavicle. “I am not going to be gentle.”
The tentacle that had already been teasing down there wrapped tightly around the newly formed cock with a brutal pace causing a muffled scream from the small skele followed by a gag as his throat formed trying to accommodate the invading tentacle in his mouth. One of the exploring tentacles under his shirt swiped almost feather light over his sternum. So many conflicting sensations kept him from just checking out. Then the tentacle around his cock stopped and just squeezed snuggly providing no further friction.
Nightmare pulled the tentacle out of his mouth and watched the small skeleton pant heavily with half lidded sockets over hazy eye lights. Drool escaped the corner of the skeleton’s mouth and his hands were kneading the wall like a content cat. Nightmare was taking in everything cataloging how the ones before this skeleton had acted on similar treatment. The skeleton’s hazy lights looked down with an almost perplexed crease on his brow as a tentacle dropped the elastic waistband down to the skele’s shaking knees. Obviously distracted by the constricting tentacle he flinched at the feeling of the slicked up tentacle at his rear entrance.
“It would be best if you relaxed and let me do this.” Nightmare wrapped a tentacle around the smaller’s spine pumping up and down slowly. “Just breathe.”
Contemplating the idea of a being such as a skeleton needing to breathe even though they did not have the system to process such an action a sharp pain shot up the skeleton’s spine. Quickly hiding his expression by forcing his forehead to the wall he restrained a desperate wail as Nightmare’s chest pressed him further into the wall. A wiggling sensation quickly found the bundle of nerves that sent a pleasurable sensation alternating between the pain. Small gasps of escaped air are hesitantly followed by shallow breaths in. The tentacle continues onward stretching without tearing anything.
“So very tight.” Nightmare set his teeth on the other’s jaw this time. “Don’t you want to make some noise for me?”
When Nightmare gets nothing from the small stubborn skeleton, it wasn’t the first time someone withheld from him, Nightmare torturously slowly pulls all but the tentacle around his cock from the other. The tentacle sliding out of the skele’s rear entrance drew out a low groan that had the skele quickly swallowing to keep from continuing. With his chest still pressed to the small skele’s back he could feel the Soul within beating as if it was bouncing around the empty space of the rib cage. With a slightly sinister chuckle Nightmare lined himself up and hilted into the prepped hole.
Ghaaaahh! The small skele scrabbled at the wall with his pinned hands and went as high up on his toes as he could, trying to escape the sudden intrusion. The magic of his entrance clenched spastically attempting to accommodate the girth that was slightly larger than the tentacle that had been prepping him.
“I am pretty sure I advised you to breathe.” Nightmare voice was void of the seductive growl he had been using on the small skeleton during this chastisement as if actual concern was setting in with the whispered instruction. “Deep breaths… now… In… out… In…”
The tentacle holding the cock slowly pumped up and down with the commands. Joints the small skeleton had not realized he had locked up slowly released as his feet returned flat to the floor and his body did not completely reject the intrusion. Bone against stone scrapped out an odd sound as he looked down through his collected magic to the cock sitting in his pelvic inlet and he whined a bit confused at the fading pain and the continued full feeling.
“Don’t worry, I’m about to start moving.” Nightmare’s growl returned at the small one’s compliance. “Don’t hold back.”
Nightmare withdrew until just the tip remained buried and then not quite slowly returned to fully hilted feeling the spasms clenching him tantalizing. Although the other was still not being vocal he had not stopped breathing and was back to panting. After a few more strokes Nightmare could feel him pushing back into him and decided to pick up the pace, he was getting close. Soon he was chasing his own end figuring the skeleton beneath him was getting close as well. His release hit him as his phone began going off in his pocket.
“Fuck!” Nightmare hilted in the small skele squeezing his wrists to the wall in his powerful orgasm, trying to come down quickly to get to the phone alerting him to an emergency. “Damn it… They had better be dying or they will be… Fuck! Killer! I know you are over there.”
A skeleton leaking black from his eyes walked from a corner he was obviously sharing with a few others. Nightmare had known they would be there from the beginning although the small pinned skeleton had probably not, but that was his own fault for not being more observant during their talk. Taking the now limp skeleton by the humerus in both arms Nightmare deposited him in the summoned skeletons arms as he turned to storm off.
“Cross’s alarm is going off, I have to go see to him.” Nightmare stared at the screen silencing the alarm. “Tend to him, clean him up… I am not done with him yet… Everyone else is on standby until I get back.”
