This is a commission for derpderpdragon on FA featuring a dragon getting an unexpected guest in his own body! Features CTF, cocksnakes, and a lot of lewd.


Through the darkness, under a line of ineffective streetlamps, David carried home a bag of groceries. The walk from store to home was thankfully short, but still, the area gave him the creeps every time he did it. He always felt like something was watching him through the darkness, waiting in the trees that crept up on one side of the sidewalk. It was like an ancient, primordial forest in those fantasy books. Unyielding woods with thick trees that almost seemed angry at the species that had cut them back. It grew so aggressively that they had to trim branches and remove vines every year.

He could've sworn that he saw some sort of meteorite crash down in the woods the other night. It had come in with a diminished flash, like someone had taken a picture with a camera, but it left a fading mark on his eyes as if he'd been staring at the sun. He heard rustling in the trees some ways in, and picked up his pace. His neighbour claimed to have seen a bear a week ago, and David was not going to wait to see if it was true.

He entered the parking lot for his apartments, and padded up the stairs to his door, unlocking it and heading inside. The door locked a second later. Time passed into the night, and after people settled in, cars stopped rolling back, and the quiet that normally comes in the earliest hours of the morning came, something approached the edge of the woods. Liquid and malleable, it rolled like a pool of water sliding across leaves and sticks, dirt and concrete, though nothing adhered to it. It approached the apartments, staying out of any light cast by lamps or bulbs, and ascended the stairs. It pressed up against the door of the dragon, and after a moment, slid under, and in.

David was having an odd dream, feeling like his body was burning up. Everything was hot, he was pouring sweat, and his cock was harder than steel. Scenes passed fluidly in his sleep, the dragon stroking and squeezing, fucking a tight hole, always close to release, and yet, never reaching it. It seemed to pass from normal sleep into a feverish buzz, growing more and more incoherent as his lust rose, until he finally awoke to eyes staring down at him from above.

A dark shape was above him in his bed, it's shape long and thick, tubed like a snake with a characteristic python's head- it was oddly familiar. A tongue slid out from it's lips to taste the air, and David gave a loud gasp- he could feel it! The tongue slithered out sensitive lips, feeling exactly like his cockhead. He jerked on the bed at the weird sensation, gasping out loud as the tongue returned. His hands reached up and grasped at the snake, eyes widening in surprise as it felt exactly like his old length- well, almost. It was coated in a layer of fleshy scales, and the texture with rises and dips felt far more sensitive than his old length.

The whole thing was a shock, and David had a million questions running through his head, mixed between trains of thought like: "How did this happen?" "What's going on?" "Why does it feel so good?" The snake's mouth opened, and he could swear that there was a smile on it's lips, the tongue extending out slightly as a clear fluid dripped from the forked appendage, falling on the scales of his chest. The scent was familiar, the consistency and wetness telling him that the snake just leaked his own pre.

"Yessss," it cooed David feeling air pass out of its mouth, the heat of another's breath washing over his scales. "Touch me. Feel me. Give yourself to me," it went on, David jerking and trying to scoot away, until his back hit the wall behind his bed, and he was faced with the sight of the several foot long cock extending from his slit, veiny and black at the bottom, before getting coated with scales and continuing up.

He couldn't believe that it spoke to him, that it wanted something from him. David immediately felt at odds with it, since no matter how much people liked to joke that men were controlled by their dicks, he wasn't about to take orders from his. It moved and extended, the strange sensation of his cock muscles moving and sliding sending shivers through his body. The hot bodyt of the cocksnaked wrapped around his neck, coming up to flit a tongue at his cheek, squeezing gently around his throat as the python's head came to stare him in the eyes, beady eyes dark and full of... Lust? Desire?

David couldn't tell, but he saw the reflection of his computer monitor, still on from his earlier study, and found an image of the same snake attached to his crotch. "Cum for me," it said when his eyes turned back to it, its snout pressing to his nose,

"N-no," he whispered back., This was wrong, and he knew it. He tried to reach up to unhook the thick snake from around his neck, but his tugging and pulling did nothing to budge it, only making it feel like he was jerking off. The only rewards for his effort were the warm jets of his own pre, hitting his muzzle and sliding off. "Submit!" the snake demanded, and David shook his head. His cock pulled back a bit, coils sliding together, creating a wonderful sense of friction that was just too pleasurable, forcing another moan from the dragon's mouth.

The snake added another loop of turgid, solid yet flexible flesh around his shoulders, and started to constrict and contract, squeezing tight and releasing, keeping up a constant stimulation. It was unlike anything David had ever experienced, and he was certain it was something no one else ever had. Jerking off was one thing, but when his cock pleasured itself by using his body, he could feel his body tremble and his length surge with need.

More of his sticky pre washed from the mouth of his new member, staining his sheets and making his body slick and lubed. The creature didn't only increase his cock size- it must've tainted his testes as well, making them overproduce. The feeling grew maddening after a while, rapidly upping his lust, filling his tingling shaft and aching nethers with a burning need to cum.

He could feel it approaching, pressure building in the base of his alien shaft, his new head growing extra sensitive, right around the bottom of the skull. Extra pre gushed forth as orgasm neared, David writhing on the bed as pleasure truly started to wrack his body- only for the snake to pull away moments before, the building running in thin, white streams from each side of the snake's mouth. It pulls away to hover over him, dripping the hot seed on his body, but denying him the full orgasm.

He panted as the near-orgasm faded to a dull ache, pounding in his shaft, the flesh feeling sore and beaten, yet still so pleasurable. "But..." he said, trying to catch his breath. "You wanted me to cum." The snake let out a soft hiss, the sound reverberating in his tip, painful sensitivity making his toes clench and tail jerk, thwapping the bed.

The snake was staring at him again, as if deciding how to eat him. "I want you to submit," it said, the snake's voice husky and wet from the fluids in its throat. "You decided to resist. You can cum when you are mine." A cold shiver ran down his spine- just how much control did this snake have over him? His legs felt weak, and though the thought crossed his mind, he didn't think there was anywhere he could run.

His head swam, the dragon feeling dizzy as he tried to work this out past the lust and the denial, fingers clutching at his sheets. "G... Get off me. I'll stick you in a chastity cage! Y-you'll never see the light of day," he tried to threaten, but his words fell flat. His tone wasn't convincing enough, his mind too addled, and the threat too impractical. Even if he could get the snake to retreat into his slit, would a cage even work...? There was just so much cock.

A minute passed, and David could feel the bubbling edge of arousal pick back up after that edging, returning to a place where he wasn't close, but still felt sensitive. The cock took action, wrapping itself around his arms and chest this time, so David could watch on in both horror and need, as the snake began to rub itself around him yet again. He saw the odd, scaly cock slide by, occasional veins crossing the dark skin. His pre covered the things muzzle, the wet splatters reflecting the light from his monitor, glinting in the dark room.

The snake's pace was slow and measured, keeping his mind addled and his body right on the edge. It knew just how close he was, likely better than he did, and it kept the movements at just the right speed to egg him on without bringing him too close to orgasm. Sometimes it would speed up, or slow down, just to control the levels of pleasure he was feeling.

Ten minutes passed, then thirty, and his bed was soaked in sweat and pre, his scales covered in slick emissions. David gulped down air. He couldn't take it any longer. "Please!" he said, louder than he meant to, his eyes blinking quick. "Let me cum! I- I need it!" He felt more words coming up, to plead and beg and cry, but he choked them back for now, his expression strained as the snake squeezed around him, head running wetly around his neck and under his chin, to kiss him on the lips with a salty taste.

"...No," the snake said. He shuddered as it pushed its way past his lips, filling out the sides of his muzzle. His mouth was warm and wet, and his eyes watered from the girthly length spreading his jaw as the head explored deeper and deeper. It delved into him, some lewd, backward form of deepthroating that David had never even thought about. The tight tunnel that squeezed luxuriously around his cock worked quick to bring him to a height, where he could feel his shaft pulsing in preparation, heavy throbs of blood, rushing up his length.

But the snake was quick to quell the uprising, pulling itself free from the dragon's innards, leaving him with a thick jet of salty pre in his mouth and over his face. The snake's maw yawned infront of him, and he saw the length's throat tighten, and then spread, as a thick glob of his clear fluid came forth, staining his muzzle with the stench of sex. David tried to think of words to say, anything that would let him get off, but his mind was blank with the waves of electric exaltation running through his improved shaft.

"You can cum when I allow it. When you are ready to be mine. When you accept me as your cock, and let me lead you to new heights." Strands formed and broke as his lips moved, droplets splashing about messily. Still, the thought of submitting to his own cock scared and rattled the dragon. That wasn't how it was supposed to work. "Tell me that you love me," his length demanded, but he couldn't. The burning lust in him was starting to quell, after they had spoken for a moment, but once it became clear that David wasn't giving in, his cock got back to work.

"No..." he mumbled, groaned, as the snake's coils tightened around him again, wrapping and squeezing around his arms and shoulders, coiling twice around his neck, the head of his shaft always staying close to his own, leaking near his ear and chin. This invader had no right to tell him what to do. David wasn't going to take this lying down! Whatever this was needed to learn that it was his cock, and he was in control.

So he struggled and squirmed, writhing against the cock, feeling it squeeze tighter out of confusion, but that was just what he wanted. He'd force himself to cum! He even put his mouth to work, sucking on the sensitive flesh just beneath his tip. He could feel it working, that orgasmic pressure rising once again, until his body washed over with waves and waves of warmth and tingles, orgasm finally hitting! It took some time, but he felt his load flow up his snake prick, soon spurting out of the dark serpent's mouth to coat the wall. Jets and jets came, making him moan loudly, his claws digging into the sheets.

He could feel his cock pumping it out, the muscles contracting hear his base, and moving in a rolling wave upwards, until it was forced out of his head. One wave wouldn't even finish before the next started, and the sensation continued for minutes, before it was finally over, his body speckled and bed soaked. The last few weak waves made more pearly cum dribble from the serpent's mouth. He caught it's gaze and gave a cocky smile, even as the snake drew up over him once more. "I wish you would have accepted me," it said, "I wanted us to be partners in this."

He was unsure what the snake mean, until his legs moved without him making them. His toes curled, and the dragon looked down in surprise. Without missing a beat, the snake started to constrict around him again, the dragon huffing at the feeling. "W-why can't I move my legs?" he asked, but received no answer.

He groaned loudly as the cock used him to spark pleasure for them both, quickly rising in his loins. Again, he felt powerless, unable to stop the snake's thick coils as they passed over his slick scales, tightened teasingly over his neck, and rubbed against each other with that odd sensation.

He watched his snakecock convulse as another orgasm hit, the snake's maw yawning wide over him as the coils expanded, transporting his jizz up and out. It sprayed out in thick ropes, landing on the floor to the side of the bed, the entire room beginning to fill with the scent of musk and semen. He shuddered as his tail flicked about, reaching up from the side of his bed as the snake untwisted from around his neck, curling with the tail, which it made act like another snake, so that they coiled together.

David gasped as it gave the flexible appendage a long lick, forked tongue sliding across the wet tip, connected by a strand of pre as it pulled away. The tail pressed to his stomach like a second of the snake, though it was slimmer and more dexterous. The pointed tip traced patterns in quick, precise strokes,showcasing a level of control so complete that the dragon was pretty sure he'd never be able to move his tail with such grace.

He groaned as the flexible limb slid down his front, tip trailing between his thigh and his slit, nesting up between his ass to poke and prod at his tailhole- oh, that was why the snake had been licking it. For lube. Great. It pushed deep inside him, his sphincter tingling with the slight burn of being stretched, but he grew used to it quickly. Unsurprisingly, it knew just how to pleasure him, even in there.

The tail sought out his prostate within a moment, and started pressing and grinding, the thin tip of his tail even manage to squeeze it by slightly bending. He squinched his eyes closed, feeling his body jerk and react, the snake making his toes curl and dig his claws into the bedding. His tail started to pound in an out, forcing in a little more to spread him wider with each thrust, picking up the pace until another volcanic eruption sent tingles through his body.

Cum bubbled up his cock and came out against his front in great gouts, splashing against his sides, adhering to and sliding down the his pecs, neck, and abs until it fell off in a slow, steady drip. The snakecock slowly pulled back, gazing down at him, leaving him with a sheen of white fluids. It brought it's head into the embrace of his hands, caressing the snake as if it were an old friend and lover. David watched himself pat the cock, nuzzle it under its chin, stroke the side of its head, and tease the insides of it's sensitive mouth.

Fear struck deep into his heart- this thing was going to completely take him over. How could he resist? Every time he felt the blissful release of cum, his despair sunk deeper and deeper, his body refusing to give in to his commands. He could wriggle his torso, twist his neck, move his thighs, but anything past that was out of his control, moving, but against his commands, responding to the second being in his body.

He huffed and groaned. "No! Stop!" He whimpered, his heart pounding as the snake caressed itself using his hands, his traitorous fingers feeling heavenly against the slick skin of his cock. They explored the divots between the scales, mushed the snake's semi-soft head, and even scooped up some of the extra jizz, smearing on it face and putting it in his mouth, before he could spit it out. "You'll be mine, one way or another..." The snake hissed out.

He could already feel his next load coming, brewing in his balls, preparing to rise up and through his taunting, dastardly cock. He closed his eyes and tried to pretend it wasn't happening as the next load covered his face and next, leaving him sputtering. He had no idea how his body could put out so much spunk, his room would likely never be rid of the scent.

He couldn't move his legs any more, nor his torso, the only control he had being his neck and head. He blinked away the excess cum as the snake used his body to the fullest, wrapping around his arm while his fingers rubbed and caressed, stroking along his leg and licking his foot with a slimy, forked tongue. It suckled on a few of his toes while his other hand ran quickly up and down the cock's side, squeezing where it could, though his girth was too big to fit between even both of his hands. His tail join in, wrapping itself around the lower portion of the snakeshaft, clenching rhythmically in a way that had him sucking in breath.

He knew with this last orgasm he'd lose all control This was it, for poor David. He'd just be stuck in the body of his cock... His length throbbed. His groin felt full, over-productive internal testes working their hardest. Every inch of his length pulsed with electric tinges, his head sensitive and growing more-so by the moment. The snake opened its mouth wide, in preparation... "Wait!" David finally yelled, his voice frightened and strained. "I-I give in. I'll do whatever you want. Please... J-just let me keep my body. Ill accept you and jerk you off and-and anything else. "

The snake stopped its ministrations, the orgasm slowly ebbing down as it turned to look at him. "Truly? You and I will be one?" David nodded and panted- he saw no other way out. Bit by bit, he felt his limbs returning to his control. "Then you finish us off," the snake said, a pleased tone in its voice. "Stroke me, pleasure us, and we will be whole." He brought his hands up and roughly grabbed the snake's head around the throat, fingers sinking into its 'neck'.

And then he stroke firmly down it's length, pumping hard. He tugged the shaft closer to him, and planted a wet kiss on it's musky lips, so glad to be able to move again. He suckled on it's tongue, and felt the hot wash of pre from its mouth, swallowing what he could down. He brought his thighs up, flanking the length, and squeezed, working at a feverish pace until he could point the snake up a touch, burning ecstacy flowing through him as more pearly cum shot towards the ceiling, sticking and dripping.

Finished, he panted, exhausted in his bed. He barely had the energy to move the limbs he'd wanted back so badly. The snake nestled up against his chest, part of it's length drawing back into his slit. He rested a hand upon its neck, and thumbed the underside of its chin. "Rest," it said to him. "Tomorrow we will find a mate. You will help my kind spread." He couldn't argue. He knew his life was changed now, for better or worse. Even after spending the last few hours drowning in a lake of orgasms and cum, he could feel the need to fuck simmering in him, only slightly abated.

He did have some friends that were interested in a threesome, some time ago... And there were a plethora of dating apps. Maybe he could make the best of a bad... Or weird, situation. David passed into slumber, while his mind filled with thoughts of pushing his new snake deep into someone's ass.
