The White Room
A shorter basically-pure-yiff story with generous helpings of tentacles and some transformation on the side.
First story, so be gentle. Unlike the tentacles >:3
Luke flopped down onto the couch, his apartment door slamming shut behind him. It had been a long evening at the bar - plenty of rowdy customers and barely enough tips to make it worthwhile - and he was glad to finally get back home.
A quick rummage in the freezer later and he had a frozen tray of... something... heating up in the microwave and a bag of chips to munch on while he waited. Not exactly the most glamarous of dinners, but after a long evening at work mustering up the effort to cook something himself seemed pointless.
He flicked through some TV channels, pausing briefly to watch the news but skipping on when he saw it was just the same old stories they always seemed to cover - recession, terrorism, poverty, and this week another freak cold front bringing blizzards to the West Coast, complete with the requisite footage of people falling over on sidewalks.
His YouTube subscriptions didn't yield much to watch either - he sat through the start of a few videos but nothing really seemed to grab his interest. At least he'd finished eating; he went over and sat at the desk, and started idly browsing the internet, procrastinating and ignoring all the work queued up in his inbox.
Looking at the time, he realised it was past midnight and that he should probably head to bed. He closed the laptop and headed for the bedroom - hopefully he'd actually get some work done tomorrow.
He stripped down to his boxers, set the alarm for tomorrow morning, and collapsed into bed. Turning the light off, he was almost asleep when he realized that he'd forgotten to lock the front door. He dragged himself out of bed, opened the bedroom door, and stepped out into... where the corridor used to be.
Luke very quickly realised something was wrong when his feet hit cold, hard plastic rather than his familiar carpet and looked up to see a very white, plain room, with nothing in it apart from a few small grates in the floor. Startled, he turned around to see that the door he'd just come through was no longer there - just a plain white wall, featureless and definitely not part of his apartment.
He suddenly felt a lot more awake - what was he doing here? How did he get here? He was just starting to wonder how it was even possible for his bedroom door to lead here when he heard a slight hiss from above him, and saw some sort of gas being let into the room. He picked up a slight whiff of... what was it? He wasn't sure, but it was definitely a bit... musky? It kind of reminded him of his ex-boyfriend, in an odd way. A good way.
As he was trying to place it, he felt his cock slowly getting harder in his boxers. Whatever it was, it was turning him on, and he was getting hornier. He didn't want to jack off here - who knew what this room was for - but he couldn't resist fondling himself just a little bit.
Suddenly, he felt something brush his leg. He looked down, and saw that something - a... tentacle? - had emerged from the grate behind him and had made its way across the floor unnoticed. Panicked, he moved his foot away only for a second tentacle to firmly grasp his other foot, wrapping itself round his ankle.
It was warm and slightly slimy, and just as he was wondering what they were planning to do to him, he felt more tentacles wrapping around his arms and torso, gripping him firmly and pressing their warm, slimy lengths against him,suspending him above the floor facing the ceiling.
He struggled briefly, but they had a firm grip, and it was useless to try and break free. Two tentacles worked up his thighs and reached under his boxers, and with a quick twist they tore them off, leaving his fully rigid member exposed and open to the air.
Luke gasped, the sudden feeling of the cold air on his cock making him feel even more horny. He felt something brush against his balls and when he looked down, he saw another tentacle rising from the floor, and this one was absolutely dripping with slime.
It wound around the base of his cock and he moaned as the warm, slick tentacle started wrapping itself around his shaft several times, enveloping it and making him strain with pleasure against the tentacles holding him.
The tentacle started moving up and down, finally giving his throbbing member some much-needed attention but going agonizingly slowly, teasing him. He started bucking his hips, trying to get more stimulation from the tentacle on his cock but the others kept him firmly in place, keeping him from getting any more stimulation.
He started to feel an odd prickly sensation on his skin where the tentacles' slime had leaked onto him, but just as he was starting to wonder what was going on, he gasped as he felt a something brush against his rear.
Guessing what was coming next, he braced as a new tentacle pressed against his ring and pushed its way in, gritting his teeth as it pushed further inside. He had put a few fingers up there before, but never anything like this - the size was uncomfortable.
That changed, though, as the tentacle reached his prostate and suddenly pushed against it, making him let out a soft moan and causing a spurt of precum to shoot out onto his chest. It pulled out again and as it pushed back in he gasped - only to have another tentacle ram itself into his mouth and down the back of his throat. He tried to cry out, but the tentacle was pumping his mouth full of the slime, and it tasted... sweet? Luke found himself swallowing it and craving more. His discomfort at having the tentacle in his rear slowly faded, and he closed his eyes as a wave of pleasure swept over him.
The tentacle in his ass started pumping in and out, making him grunt slightly as it hit his prostate, precum dribbling out of his cock with every thrust. He'd never felt this full before, and he loved it. His precum was pooling on his chest, mingling with the slime and dripping onto the floor.
He felt more tingling on his arms and looked over to see that his skin was turning green and scaly where the tentacles were holding him. What was this... creature doing to him? Before he had time to worry, though, the tentacle in his mouth unloaded a fresh load of slime and he eagerly swallowed it, feeling the prickly warmth as it traveled down into his stomach.
He felt the tentacle wrapped around his penis slowly uncoiling, the combination of its slime and his precum dripping down his now-exposed cock, and he looked down to see a new, larger tentacle poised above his cock.
With one swift motion, it plunged down and sucked his penis into its warm, slimy depths, making Luke moan with pleasure as it slowly started moving back and forth, lapping up all his precum as the tentacle behind him kept up its steady pounding, slurping each time it pushed in and out of his ass, the slime it was secreting now spilling out and onto the floor below him.
Luke was starting to get close to cumming, and the tentacles must have sensed it - the tentacle fucking him slowed down, and the one pumping his cock pulled away, leaving his cock throbbing in the open air, desperate for attention.
He felt a ticking at the head of his penis and looked to see two tentacles caressing it - one wrapped round the slick head, moving gently up and down but staying off of his shaft, making him moan with the intense sensation as it pleasured the most sensitive part of his cock. The second one gently pushed into his urethra, and initial discomfort gave way to pleasure as it pushed down inside him, stimulating him from the inside.
As it reached his prostate he felt a wave of pleasure rush over him, and he almost came right there. The tentacle wriggled around inside him, stimulating his prostate continuously and making Luke arch his back and close his eyes in pure pleasure. He was so close now - so close to cumming.
The tentacle in his ass started moving much faster, and as his body jolted from each thrust, he felt it swell up as it unloaded huge amounts of the slime into his ass, filling him up and making him moan even louder around the tentacle in his mouth. It was too much, pushing him over the edge.
He tensed up as he approached the point of no return, but just as he was about to orgasm, the tentacle buried in his cock swelled and he felt it squirting slime inside him. It felt like having an orgasm in reverse, and Luke could do nothing but buck and moan as the tentacle pumped its warm, sticky goo into him, keeping on the edge of pre-orgasmic bliss but not letting him cum.
He felt his testicles start swelling up and becoming heavier as the slime filled them, too wrapped up in ecstasy to notice as green scales started appearing on his groin, the precum-mixed slime changing his skin wherever it touched.
The scales were progressing along his arms and legs, too, and Luke murred as he felt the same warm, tingling sensation from the huge load of slime buried in his ass. He let out a small gasp as he felt a tail push its way out from the small of his back, but just as he tried to move it a tentacle coiled round it and held it back, away from the tentacle still pulsing load after load of slime into his ass.
As he lay there suspended, desperate to cum, he felt more and more of his body changing - the scales sweeping up his chest and neck, and then he moaned as his face grew, forming a muzzle and causing the tentacle in his mouth to unload another load of slime, the sweet taste washing around his new mouth and making him even more desperate to cum.
As a row of spines emerged along his back, he felt his feet and hands grow more claw-like, his muscles tensing as they grew to fill out his lean frame. It felt so good, but that tentacle was still buried in his cock, pumping it full of slime, keeping him on the edge.
As he watched, his cock grew longer and more tapered, and he moaned as he felt it push out from him, the tentacle buried inside it pushing further in as his cock grew several more inches around it.
As he hovered on the edge of orgasm, he felt the last of his scales emerging with a wave of pleasure, and just as the thought he couldn't take any more, the tentacle buried inside his cock gave one last thrust and pulled out, while the cock in his ass rammed into him, finally pushing him over the edge and letting him cum.
Luke's body spasmed as the first load of cum shot out, arcing clear over his head and splattering on the wall behind. As the slime in his heavy balls swirled and pulsed, he came again and again, huge globs of cum splattering over him and the ground, soaking him in his own juices.
The tentacle in his mouth withdrew and he let out a load gasp as the one in his rear pulled out too, pumping one last load into him as it left. As the tentacles gently lowered him to the ground, he was still bucking as shot after shot of cum left him, his face covered with his pent-up seed.
As the tentacle retracted back into their gratings, Luke laid there, twitching gently as the last few shots of his cum splashed out onto the floor, exhausted from his ordeal, slime leaking from his loose ass.
As he gingerly stood up on his feet, the dragon admired his new body, green scales glistening with slimy cum, hands and feet ending in sharp black claws, spines running down his back and onto his tail - and definitely a lot fitter than he was before.
A door appeared in the wall, and he stepped through into his dimly-lit bedroom, the last of the cum dripping out of his huge cock onto the carpet. As he laid down in bed and started processing what had happened, he knew only one thing for sure - he hoped the tentacles would be back.
