Justin was looking through the options on the chronivac, thinking that they were a clothing catalog.
"You know, I could use a new speedo." he thought to himself as he clicked the speedo option on the left side of the screen.
He found a red speedo that he thought would fit him well. He clicked the enter button.
Meanwhile, Jeff was downstairs getting a coke when he began to feel very strange. He quickly excused himself and ran upstairs, finding that he was irresistibly drawn to his room, where Justin was.
Justin was wondering where the purchase button was when he suddenly noticed that his clothes had vanished. He was completely naked! But before he was able to do anything about it, Jeff burst into the room. Before either of them could say anything, Jeff's clothes vanished as well. Jeff felt his insides begin to dissolve, and as he walked towards Justin's naked body his internal organs disappeared completely.
Justin watched as his friend got on his hands and knees. Jeff wrapped his arms around Justin's waist and pulled himself up, an action which should have made both boys fall to the ground, but for some strange reason, did not. No longer in control of his body, Jeff stuck his legs together, and, with inhuman flexibility, stretched them between Justin's legs and curved them up his buttocks where they joined with his hands. Jeff began to shrink. Justin felt Jeff's skin rubbing against his body as he shrunk, all the while his body sticking to Justin's until he was skin-tight, like the speedo he was about to become.
Jeff's hands melted into fabric. Jeff groaned as his feet stretched, blending with what had been his hands. Jeff's legs began to thin, stretching across Justin's butt. Jeff's hair sucked into his body, and his arms began to lose their muscle, flattening until they were skin-tight, wrapping around Justin's waist. Jeff's head suddenly exploded forward onto Justin's package, stretching and expanding up until he blended with the rest of his transformed body. Jeff, still conscious and aware of his surroundings, could feel Justin's sweat soak into his inanimate body.
For the final part of Jeff's transformation into Justin's speedo, Jeff quivered as his color changed from what had been his skin tone to bright red. Justin had a brand new speedo.
