"Woah dude,you feel awesome on me" Justin says as he does a couple air thrusts that force his cock to grow inside of jeff's tight form. "Dude, I'm already cumming just thinking about this. I'm wearing you around my dick."
Jeff was terrified while also being a little turned on about his whole situation. He had a girlfriend but this made him feel, complete in a way. He had a purpose and that was to make Justin look hot, a purpose that he loved the thought of upholding. With every thrust Jeff was pounded by Justin's growing cock.
"Woah dude, are you enjoying this?" Justin looked down at his speedo, which had already been pulled far from his skin by his own erection.
Justin reached his hand down into his swimsuit and started to pump. Again and again, pumping his jizz straight inside of Jeff.
In about half an hour, Justin was tapped out and went to rest in front of Jeff's computer. He had a full load drying in the super absorbant skin of his best friend.
"Chronivac, turn anything into anything. Hmm."
