After school everything was going to plan. Snake had gotten Ryan's abandoned clothes from his P.E. locker tossing them into the backseat of his beat up car. Ryan would be tossed in next once they were near the Standish home. A little while later he'd go home and make his excuses and stories. After that... well Snake didn't want Ryan to catch any hint of those thoughts until it was far too late.
Snake brought the car to a stop and made sure that Ryan would hear his thought, "You're awfully quiet Standish."
"Just ready to be human again."
Jason shimmied around and dropped his jeans to the floor. Then Ryan felt himself being removed in the same awkward fashion and casually thrown into the back seat with his clothes and the assorted teen detritus. After a little while the jock went from stained white to a flesh colored object that continued to grow into a naked young man. He was flushed and obviously dirty. He wanted a shower to wash the stinking musky smells off almost more than anything. The one thing he wanted more embarrassed him.
He started putting on his tee shirt and then stopped.
"Fuck Standish, get a move on, you want someone to come by and see you half naked?" Snake was working to get his own jeans back on.
"No, I want to be your jockstrap."
Jason was surprised by this and just turned around to look at him. "What?"
"I want to be your jockstrap, Jason."
This was too perfect, Snake thought to himself. He's already addicted to me. But what about Vinnie and the police? No one had actually seen him with Ryan and would Vinnie do anything if his tormentor was a cum addicted slaveboi? He didn't think so.
But he had to push Ryan. "Okay, let's hear you beg for it then."
Ryan did not want to do that. He loved massaging Jason's cock, soaking up his cum, even being a bit dirty, but he hated being humilliated for it. But he did want to feel himself changing back into fabric around Jason's body. "Please let me be your jockstrap," he asked in as plantive a voice as he could manage.
"You're willing to be my pussyboi all the time I'm not wearing you?"
"Yes!" he said with some reluctance.
"Then get back up here and suck me jock," he said pulling off his jeans yet again. Ryan tore off his tee and leaned all the way forward to plant his face on the hard cock with its snake tattoo. He started sucking and before long he was rewarded with a few tastes of precum. He felt his body starting to transform as he worked his mouth over his owner's penis. He wanted him to cum before he completed his transformation, his shrinking arms and legs moving to encircle his body. It was very close but he finally got his first taste of cum as a (mostly) human. He felt it hot and salty going down his throat as the final changes took place. And then he was being covered up again by the familiar blue jeans.
Gawd, what had he done to himself? He was nothing more than a dirty and smelly jockstrap. But it felt so good to be milking a cock again.
