Inspired by your post hope you enjoy ^_^
Jon had not expected to find his future self down in the tunnels when he snuck down to investigate. He had expected even less to turn a corner and find it clearly…aroused, cock hard and heavy between its legs. Jon couldn’t help but stare for a moment, but that was okay right? Technically it was him, just a bit in the future? He decided not to examine any little hints of envy he felt, shoving those into the little box in his mind. As these thoughts flitted through his mind he realized that he was no longer unnoticed. Eyes opened up, more than the normal two, each fixating on him, except its original two which seemed hazy. He felt pinned, like a physical force was holding him there. It tilted its head as though considering something, instead of words it made an odd humming sound.
As the monster, and it certainly seemed much more monstrous than before at the moment, crawled toward him, Jon tried to move. It was twenty feet away, ten, moving slowly but deliberately, with a look in its eyes that Jon didn’t know how to quantify. He needed to move a few more seconds it would be on him, he hesitated briefly, surely it wouldn’t hurt him, it was him? His hesitation broke as it lunged at him growling, and with a cry Jon broke free of whatever was holding him.
He managed to get about halfway down the tunnel before it was on him, moving faster than Jon could ever hope to. Pinning him to the ground, it should have hurt but its tail wrapped around him, both restraining him and cushioning his fall. Its muzzle pressed into the back of his neck for a moment as though smelling him, no not as though, it was sniffing him. A click to his left had him groaning, of fucking course, the tape recorder sat innocently just out of his reach, wheels turning. Jon chose to ignore that, just considering he had bigger issues at the moment.
“Okay listen, I know you are technically me so, wh-what are you-ahh,” Jon yelped as he felt claws shredding the clothes from his lower half in a few quick motions. It seemed to at least not be cutting him, though…Good lord was it going to eat him? Had it completely lost its mind? Why was it doing this? His mind refused to jump to the most logical conclusion at the moment, that was absurd.
“D-don’t! Put me down!” Jon’s struggles were futile, his hands were pinned to his sides by its tail, and he could even reach any part of it to bite. He felt panic welling up inside him alongside fear as he felt its hot breath against his arse. He was going to be eaten by his future self, this was insane, he almost wanted to laugh. Only instead of the sharp sting of teeth, and the crunching of bones, he felt something pressing between his legs. It was rough, and wet, a bit bristly, and Jon realized what it was a second before it was sliding inside.
“Nghh,” Jon’s complaint broke off into a moan as its tongue slid inside him, it was a stretch, but a manageable one. Though if this was an indication of how things were going to go, this was hardly going to be the biggest thing it would make him take. It was thin, but long, pressing inside him, rubbing against his wall, and it seemed to know exactly where to press to drive him insane. It wasn’t long till Jon was clenching down his whole body trembling as he came, before going limp hoping that would be it. Only the tongue didn’t stop, quickly pushing him into overstimulation, pressing and pressing, Jon wondered if it was trying to squeeze into his womb.
Luckily for his sanity and internal anatomy it seemed to be satisfied just pushing Jon into a second weak orgasm, his walls spasming as its tongue slid back out, with a wet sound rolling back up into its odd mouth. The other him, the monster, chittered at him, though Jon had no clue what it was trying to convey. Still it had stopped and Jon sighed in relief, that had been a lot, but at least it was over.
As was his luck the universe seemed keen on immediately proving him wrong as he was lifted up, claws and tail holding him so tightly he couldn’t possibly get free. Something hard pressed against his backside, it was hot and wet against him, and he probably didn’t need the eye to tell him it was his other self’s cock.
“You can’t be-,” Jon stuttered as the head of its shaft, slightly flared, pressed against the opening of his cunt. It slipped past the opening brushing his clit, which made Jon whimper, still overstimulated from his other two orgasms. He could feel it slide along his stomach, and god it was huge, there was no way. The first failure didn’t stop it as it tried again, once more slipping past, Jon whimpered, there was no way, it couldn’t possibly?
“Stop it won’t, you can’t make it fi-“ once more the universe was laughing as it repositioned him, pinning him tight to the floor, thrusting home this time. He couldn’t bite back a scream, the sound echoing down the tunnels, as it thrust shallowly inside him.
Oh god he was going to die, there was no way he could take this and he knew from what he had seen this couldn’t be much more than the tip. It was going to tear him open, kill him right here, he struggled, he had to get free, but it’s claws just tightened in warning, slowing sliding him back off its cock, with a slightly apologetic tone to its humming.
“Thank you,” Jon mumbled, as it started to pull out, thinking it was understanding, before crying out his whole body trembling. What he had thought were just odd bumps on the shaft flared out now into what felt like spikes, why did it have barbs? The pain made him clench down harder, which only made the feeling worse. He tried to beg it to stop moving, please just hold still but the only word he managed was please.
It didn’t stop the future him from shifting its grip to wrap a clawed hand around his waist. He froze, no no please, as it pulled him back down it was like an arm was being shoved into his cunt, stretching him wide. It hurt, it felt good, it was too much as it pressed deeper, and deeper, making space for itself inside him. He let head fall forward only to catch a glimpse of his stomach as it lifted him slightly. His panting breaths came faster, realizing he could see the outline of its cock inside him.
He was pretty sure at that point he had blacked out for a bit, his body going limp as it used him. He was just a toy, a cocksleeve, easily maneuvered by his other self, just here to make it feel good. Not that he didn’t feel only pain, in fact as its thrust got a bit rougher it pressed hard against the spot inside him that had him seeing stars. He didn’t think he could come again, but well, as was said the universe over proving him wrong, his vision went white as he threw his head back, not even trying to hold back his whorish moans. Not like anyone else was here to hear, just the two of him.
Apparently his orgasm had been encouragement because to his other self as its grip tightened. Jon blinked, no surely not, his mind refused to acknowledge that what he had felt pressing against him was a knot. Whether he accepted it or not thought didn’t really matter at the moment. Jon tried to object, tried to beg, but he couldn’t get the air to, choking on spit as he felt his entrance start to stretch further.
The monstrous him grumbled clearly unhappy that his body wasn’t just accepting what it was trying to do. Jon felt the absurd instinct to apologize, sorry his body had limits, hysterical laughter bubbling from his lips. It paused, then Jon felt pressure against his clit, rubbing gentle circles, pushing him once more into a weak orgasm. As his body relaxed again the monster took the opportunity, managing to finally pop its knot past the last bit of resistance that had been lessened by his orgasm.
“Ahh,” Jon screamed, in equal parts pleasure, pain, and shock, his stomach was distended around the knot, enough to make him look in the early stages of pregnancy. As if that wasn’t enough he felt warmth inside and horror washed over him as he realized his other self was now coming inside him. The knot kept anything from leaking out and Jon could only watch in terrified awe as his stomach swelled further.
Mercifully he did pass out at this point again, falling into inky blackness as all his senses were overwhelmed, though it did manage to wring another orgasm out of him as his vision went dark.
He wasn’t sure how long he was out but when he came too his face was pressed into something soft, and he was no longer lying on the floor. Instead there was something warm beneath him, his vision resolved and he realized he was now lying on top of his monster self. It was cradling him in all four of its arms, pressing his face into its neck fluff. Jon was almost surprised by how safe he suddenly felt, considering the events of the last however long.
Speaking of which, his legs were still stretched wide and he could feel pressure that said the massive cock was still locked in his cunt. He gingerly tried to lift his hips up, but it only made him cry out as the knot tugged on his insides. Abandoning the notion of getting free for now he let himself collapse back against its warm stomach. It chittered at him the vibration causing its cock to shift inside him, pulling the last of his sanity together he managed to glare.
“Don’t move,” He tried for a firm tone but a lazy thrust of its hips had him practically squeak the words out. It chittered again clearly laughing, but its eyes were clearer now, and Jon was suddenly aware that it was in heat. He groaned, unsure where the knowledge came from but well it made sense. He also got the feeling that this certainly wasn’t over, that feeling was reinforced as it gave another lazy thrust of its hips, before unrolling its tongue flicking over his clit. Jon just hoped he kept any part of his sanity by the end of this.
