Rubber Roommate (Rubberization, TG, 2nd Person)

You’re at your desk, typing away at your keyboard, when you hear the creak of the door sliding open. Followed by the squelch of something sticky against the floor.

“Good afternoon, Plastine,” you say, without looking up from your work. “Did you have a good day?” 

“Aww, I was trying to surprise you!” comes a squeaky, helium-high voice. 

Sighing, you remove your headphones and turn to look. 

Closing the door, Plastine pulls herself up to her full (well, not quite full) height and pouts like a naughty child. “I was going to give you a great big hug!” A glob of liquid rubber drips from her slimy body and strikes the floor with a plop–without a pause, she steps onto it, immediately sucking it back up.

“You can still do that,” you say with a laugh. 

“It’s not the same!” she replies, jumping in frustration (though the sticky nature of her lower body means she never leaves the ground). Nonetheless, she slithers her way across the room towards you, leaving a trail of bubbling rubber goop in her wake, and wraps her arms around you, squeezing tight. You hug her back. 

After several seconds, the two of you pull apart with a sound like someone pulling a sticker “Thanks, Plastine,” you say, turning back to your work. 

You’ve almost put your headphones on when you hear the squelch of her crossing her arms again. “Aw, come on! It’s, like, night o’clock already. Can’t you call it quits for the day? I have so many fun games I’ve been waiting to try with you.” 

You turn back to her with a frown. “I’m sorry, but I’ve got a massive backlog to work through. I really need to make some progress before–” 

“Urrrrrgh, you’re always saying that! Come on, just take one night off! You won’t regret it!” 

“I’m sorry, but I really can’t. I–” 

You cut off as she throws you the poutiest pout you’ve ever seen someone perform. It’s almost enough to make you reconsider. 

“Fine!” she says, seeing you aren’t going to budge. “If you won’t stop on your own, I’ll have to make you!” And before you can say even a word of protest, she surges, swelling into an enormous tsunami of rubbery slime, which falls on you without even a second of pause. You barely have time to raise your hands in defense before she slams into you. 

An instant later, you find yourself underwater. Or underslime, at any rate. Everything is dark, and when you struggle for air, you find it impossible to acquire. “Plastine! Plastine!” 

Whether in response to your cries or because she’s finally remembered humans need oxygen, a gap opens up around your head, and light and breathable air return to you. You gulp it down eagerly. 

You find yourself in an enormous rubber cavern, large as your room (has she expanded to fill it?) and the bright yellow of an eggyolk. Swallowing, you stumble forward, sinking your feet deep into the sticky, slimy gunk of Plastine’s interior. It’s like walking through mud. 

When you place your hand on the wall to keep yourself upright, the entire cavern shivers, and a high-pitched giggle booms into your head. “Hehehe, hey, stop! That tickles!” Frowning, you sink your hand deeper, and Plastine breaks into giggles. 

“Plastine, what are you doing?!” you cry, cupping your hands to amplify your voice over her laughter. “Let me out of here!” 

The giggling slows. “Hehe, no way! You promised me we were going to get to play together soon, and I’m cashing in that!” 

“Come on, Plastine, be far. I told you I have work to do!” 

“Oh yeah? Well, let’s see if you still have work to do after this!” 

Before you have a chance to ask what she means, a number of little lumps form in the floor of the cavern. Rising like snakes, these rubbery tentacles twitch and stretch and finally shoot across the room towards you. Wrapping around your limbs, they squeeze tight, binding you in place even as you struggle to escape. “Plastine!” 

As you blush, one of the tentacles slips under your shirt and starts to tickle your belly. “Hehehe, I’ve got you!” 

“Plastine!” You squeal, more in surprise than anything, though you can’t help but admit this situation is making you feel a little strange. “Plastine!” Before your legs, you feel a sudden tension in your jeans. 

It isn’t long before Plastine’s tentacle, wiggling faster with the second, happens to catch it. At once, it and every other tentacles freezes and retracts. Stumbling back, you blush and catch yourself, worried you’ve offended her. “Plastine, I…!” 

Her giggling returns, louder than ever. “So, you’ve into that kind of stuff, are you?” The cavern shakes with her chuckling. “I know a game you’ll really enjoy then.”  

Her tentacles return, with speed. You squeal in fresh surprise as they coil around your limbs and squeeze tight, binding you in place even as one of them unbuckles your pants. Pulling down your jeans, they grapple with your underwear, sliding it slowly down your legs and freeing your erect member to pop into the open. “Plastine!” you squeal, face red with embarrassment. 

The goo at your feet trembles and rises in a mound, which quickly takes the familiar shape of your roommates. Climbing up your legs, she fixed you with a smile and wraps a playful hand around your shaft, as if it’s a little animal she’s planning to pet. Her touch strikes you with a spasm of pleasure. “P-Plastine!” 

Giggling, she licks her lips with a long, yellow tongue. “Hold still~.” And before you can even react, she wraps her mouth around your shaft, slides all the way to its base and, sucking hard–harder than you’d ever imagined possible–pulls herself back up again. 

Incredible pleasure, inhuman, floods your form, searing you from one end of your body to the other. Your member, already intensely erect, grows so hard you almost scream. You’ve never felt such ecstasy.

Plastine, still giggling, despite her full mouth, sucks even harder, her sticky, plasticky tongue gliding around your shaft and leaving every inch of it coated in her slime. It seems to be acting as a lubricant: with every passing second, Plastine’s lips rise and fall faster, and the pleasure shoot through your form grows stronger and stronger in turn. Legs trembling, you almost fall–only the grip of her tentacles keeps you standing as you throw back your head and moan, eyes rolling back in lust. 

Finally, you reach your limit. You can hold it in no longer: Plastine’s lips are simply too good to resist, and the pressure they’ve formed in your groin is like a bomb waiting to explode. You have to release it. 

Nerves charged like electrical wires, you jerk your hips and cum with a scream, your eyes rolling back, your skin slick with sweat, your heart pounding, pounding, in a desperate attempt to keep you erect. Your balls tremble, your cock throbs, and your semen explodes in a torrent from your glans, filling Plastine’s mouth so fast her cheeks bulge as she struggles to contain it. When the tide finally comes to an end, you collapse, sagging in defeat. She passes your semen from one cheek to the other, head cocked as if savoring the taste, before she finally swallows. “Mmm, not bad.” 

And before you can stop her, she wraps her lips around your shaft and starts sucking again. Her touch is electric–you scream in surprise, fighting to push her away–but it doesn’t take much for your member to rise, rigid as wood, once more. You can only squeal and give in. You certainly don’t have the strength to stop her.

Naturally, in your current state of sensitivity, it isn’t long before you cum again. As you fill Plastine’s mouth for the second time in as many minutes, you feel as though some of your lifeforce is accompanying your semen. Unfortunately for you, she isn’t satisfied with her second mouthful either: eyes wide in delight, she carries on sucking and sucking and slurping and slurping, until at last–

By the time she finally comes to a stop, you’ve lost track of how many times you’ve ejaculated. You think she might have sucked your soul out. 

Pulling back, Plastine giggles as she looks down on you. “Ooops,” she says. “Maybe I got a little carried away there.” She giggles. “Don’t worry! I’ll make everything better though!” She vanishes into a puddle of herself, leaving you to stare at the bubbles.

Around you, the wall of the cavern ripples as if in an earthquake. Before you have a chance to figure out what’s going on, they start to shrink, collapsing like a deflating balloon. You can only watch through wild eyes as the wall of rubber falls towards you like a tsunami. Not again! 

The rubber strikes you with a splat, instantly covering every inch of your body. Your clothes, already half-removed, dissolve instantly on contact with it, leaving your poor, exhausted body entirely exposed to the flood. Like a skinsuit, it clings tight to you, making your skin tingle all over and your penis snap straight back to full erection. Is she an aphrodisiac? 

An instant later, her rubber presses over your face like the world’s tightest mask, instantly cutting off all sight and air and all sound save the squelching of her body. You squeal in surprise, squeal and thrash, but instead of releasing you, Plastine simply grows that much tighter. All you can do is squirm. 

Just as you think things can’t get any tighter, the rubber slips between your lips and stretches them wide. What follows is an interesting insight into the other side of the blowjobs you’ve just experienced: forming a thick phallus of slime, Plastine forces it straight down your throat, leaving you to choke as it worms your way down your esophagus. 

As if this isn’t enough, you soon feel something very similar working its way between your buttcheeks. You have just enough time to cry out in horror before it slips through them and straight into your rectum, wedging itself so hard into your ass you’re surprised it doesn’t meet the other tentacle somewhere in your middle. 

Skewered like a hung of meat, you can only close your eyes and moan as the slime tightens around you, squeezing you till you’re certain you must pop. Instead, impossibly, you feel yourself compacting, crushed, as if your atoms are overlapping, squeezed closer and closer and closer until together until feel you must go critical and–

The tensions abates and intensifies simultaneously, different areas of your body affected in different ways. Your waist and shoulders snap inward; your hips snap outward. Your fingers and toes grow thinner, more delicate. Your nose and your jawline soften, assuming more feminine proportions. Slimy ears sprouted from your head and a giant, squishy tail from just above your rear. And your cock– Your cock collapses inward with such speed that you can only moan and scream, shaking in delight as Plastine’s slime instantly fills your new hole. The sensation of fullness is incredible–between the slime inside you and the slime outside, you can’t tell if you’re going to collapse or explode. 

And with every second, the tingling of your skin grows stronger and stronger too, melting your mind with the intensity of the sensation. You have no idea what it’s doing, but for some reason you’ve started hearing squeaks as the slime rubs against you. 

Slime pours through your lips and into your gullet, stretching your insides wider and wider and wider, until at last you can bear the feeling no more. Something must give: you’re going to explode! 

About a nanosecond before this, Plastine’s slime retracts: her tentacles snap out of your mouth and your butt and your tight new little pussy, and her rubber rolls away, leaving you to fall to the floor of your apartment with a squeak and a moan. 

Sitting up, you squeal in pleasure.

“Um, h-hey,” says Plastine, looking down at you. Why does she seem so much taller than you now? 

Looking down, you find yourself staring at a pair of visible if rather petite breasts.

“So, um, I might have gotten a little carried away,” says Plastine.
