Panting, Langston walked over to the computer. He logged in, then made some selections in the chronivac app. He turned around, a cheeky smile on his face. He walked back over to Matt, who was lying on the bed.
“This should make things more fun.” Langston said, his face inches away from Matt.
“I’m down for anything.” Matt gasped in response, wrapping his arms around the back of Langston’s neck and pulling him down. They passionately kissed, tasting each other. Then, Langston pulled away, and began kiss Matt’s hairless chest. Matt leaned back, and rubbed his body against the sheets, feeling Langston’s wet lips as they moved down towards his crotch. Langston was kissing his nipples and running his tounge between Matt’s abs. Langston sucked on Matt’s cock for a moment, and then moved his head lower. Matt looked up, and saw that adorable smile on Langston’s face, in between his legs. Matt felt Langston’s lips on his asshole, gently kissing it. Then, Langston’s tounge entered Matt’s hole, gently licking and rounding the edges.
Fuck, his ass tastes amazing, Langston thought. Just then he felt the warmth pulse through his body. His changes were starting. It was a good thing Matt was in the centre of the bed. Langston positioned his muscular body on the small lower half of the bed, his bare feet against the wall. The room started to grow bigger, and as he fucked Matt’s ass with his tounge, Langston felt his bed and Matt’s body growing larger. He didn’t have to crouch so much anymore. Both Matt and Langston were sweating with the heat of pleasure, but Langston’s body was producing more than normal. The smell of his body odour filled the room, turning Matt on even more.
Langston slowly began to straighten his body against the wall as he grew smaller, his legs merging. He flexed his sweaty feet as they flattened and bloomed into a suction cup. The sweat on his feet remained on the forming cup, and as it flattened into thin plastic they stuck to the wall. Langston was significantly smaller now, only about 4 and a half feet long. His body started to thin, condensing in on itself. His fingers began to pull into his palms, his arms pulling into his torso. His shoulders were diminishing too, the muscles and bones contracting with a wet crunch as his stocky torso changed to a cylindrical shape. His knees, bent to allow him to fit onto the bed, began to straighten as he shrunk faster. At his moist suction cup (now bending back and forth more with Matt’s slow gyrations as Langston stiffened), the healthy dark brown of Langston’s skin began to deepen into an inhuman black plastic colour.
Still rimming Matt’s now giant asshole, his face was gently extending forward, his head separating into the base of the glans. He was shrinking fast now, and he could feel himself hardening into firm plastic. He straightened his thickening legs fully, only a foot and a half long. Matt’s expectant asshole was right in front of him, but he could no longer reach. Langston’s arms rested against his now cylindrical torso, and merged with it.
“Don’t stop…” Matt murmured, looking up. His eyes bugged. Attached to the wall facing him was a slowly diminishing cylinder of black plastic, with Langston’s face on the tiny head of what was clearly turning out to be a large sized dildo. Matt stared at the tiny eyes, watching the dildo wiggle slightly as carved veins pushed out on its sides. Langston looked pleadingly at Matt as his face lengthened, his nose and ears sucking into the stretching flesh. Matt sat up, and crawled over to the strange object. It smelled of Langston’s intoxicating scent.
Matt gripped Langston’s torso, looking at the tiny eyes and mouth, opening and closing. It’s lips were flattening, and it’s teeth and tounge were gone. It seemed to be trying to say something. The tiny lips mouthed “Use me,” then vanished completely, leaving only a tiny slit. Matt needed no further invitation, leaning back on the bed and positioning himself.
Langston saw Matt’s hole, coated in his own human saliva, coming closer. Langston was still sweating, and although the smell hadn’t changed, it was no longer human sweat. Lubricant was oozing out of the hard plastic dildo as it hardened inhumanly. He made contact with Matt’s rim, and forced himself in. Matt gasped as all 10 inches of Langston’s hard plastic body filled him. Inside, Langston’s head stretched further down, gently tickling Matt’s prostate.
This is incredible, Matt thought in between waves of pleasure as he felt the warmth of his own changes begin. Langston could not think of anything, completely consumed with his new body’s function as a sex toy, giving Matt the best fucking of his life.
