The "real" Rob stared dumbfounded at his naked doppleganger, who clutched a medallion in front of his genitalia.
"Dude, who are you?"
"I'm you dude."
The naked chick stared critcally at Jared, whose growing erection made his trouser snake point directly at her.
Jared decided to stop hiding the unhidable and draped the medallion around his neck. He tried to make his penis avoid pointing toward the girl until it reached full erection and pointed upward.
"Sorry," he said to her. "It's all because of this medallion I think. Whenever it comes in contact with someone else's clothing it makes the wearer turn into the person who wore it last. Your friend Rob was playing with a sock of mine when I surprised you."
Rob, stoned to the gills, was mystified.
"Hey man, does that mean I can turn into a dog too?"
"No--"
"Oh my God I'm a weredog!"
"No! It's the medallion that--oh, never mind!"
Rob, whose mind now totally blown, just stared. The naked chick began laughing and turned to her stoner friend.
"Hey Rob, is that really what you look like naked?"
"Uh..yeah.."
"I see." Turning to Jared she smiled and purred, "I didn't know rob was so well-hung."
Jared smiled back at her.
The Rob Judy knew had been a filthy, out-of-shape, sloppily groomed wreck whose libido was usually replaced by a continual drugged-out lassitude. This naked Rob was a an ideal, fit and virile replica--and an obviously horny one.
Jared puffed out his chest and walked up to her, stopping just after his cock brushed against her naked chest.
"Listen Judy. I'll be frank with you. I'm really a 17 year old boy named Jared. You happen to be an 18 year old girl named Judy. Now that we know who each of us really is, I think we should get to know each other even better."
" 'Know' ?"
"As in the biblical sense."
"Huh?"
"Aw, screw it!"
Jared threw Judy on to the floor and slipped himself into her.
"Oh, now I get it!" laughed Judy, as Rob looked on--first with puxzzlement and then with gradually dawning anger.
"Hey!" he thought, "I can't stand by and watch me fuck with my girlfriend! How dare I do that to myself!"
He looked at the dirt next to Jared and Judy's writhing bodies and saw the medallion lying the dust--it had been taken of before love-making. "I'll show him!" thought Rob. He snatched up the medallion.
