Looking down at his crotch Steve felt the warm pressure building. Something was definitely happening, and it wasn't normal.
He mentally checked that thought, he had just been attacked by his former bullying victim who was now looking like an Olympic swimmer but with the anatomy of a Ken doll. The attack had been not entirely unpleasant but something he just didn't want to even consider at the moment.
Now this was happening to him. He felt a little dizzy at the shock and fear, the reality of his situation sinking in.
His pants looked different. Just plain jeans before and he had needed a belt to keep them from falling off, but now, they felt tighter. Every passing second they felt tighter.
"Hey what is happening to your pants man?" the voice of James came from behind him. Great, somebody else was noticing the strangeness happening to him. He felt his face turning red.
"I uh... I don't know" was all he could say as he turned back around to face James. They were both looking at his legs, and his crotch.
His pants grew tighter, and tighter, Steve let out a little grunt as they began to constrict his legs, the material was different now too, it wasn't denim at all. As it got tighter it began to grow smoother, then stretchy, with a slight shine to it.
"Oh my god. I think it's-" James began to say. But Steve cut him off when he started to yell.
"No get it off me!" he began to swat at his legs and pull at his waistband, but the pants were shrinking now. Slowly they crept up his legs, tighter and tighter he could feel them squeezing his ass together and crushing his balls.
"Ahh!!" he cried out again, gripping his crotch as his shorts grew smaller, climbing his hips, finally becoming the little briefs he knew they would be.
The color was exact. The same as Keith's. A sort of denim blue but a little brighter. Beneath his hand he felt his groin being crushed by the tightness of them. No, not just crushed, re-formed.
"No... please not my.. ungh!" he bent double, feeling the strangeness of his bulge in his tight underwear. His genitals had been smoothed away completely, and all over him his body was aching as it swelled slightly.
"Dude. You look like Keith." James said taking a step back. The entire process had only taken about 30 seconds, to Steve it felt a lot longer.
Adam was slowly sitting up cradling his head.
"Oh shit." was all Steve could think to say, his voice sounding slightly deeper now.
