Dave had to cure this somehow. Maybe this would all wash off. All cried out, he went back to the bathroom, prepared for the scruffy mess of a late teen he'd be seeing in the mirror. The light was bright and he had changed a lot, his eyes widening in shock even with being prepared for what he'd see.
"Is this really me" he whispered in his new deeper whisper. "Shit"...maybe he could wash his foot. He lifted up his leg, putting his somewhat animal-seeming size 12 with the brown wiry hair in the sink as he turned on the tap. He almost fell over with a shock from the awkward position when he saw he now had some scraggly brown hairs growing all down his arms, too, and even a little on the back of his hands. Way too animal of a look for his liking.
Dave washed and washed his foot, the water soaking the hair down and making it darker, but after a few minutes it looked the same to him. Maybe he could shave it off, but he'd never shaved before and couldn't find a razor in the mirror cabinet. "Goddamn it!" he said, smacking his hand against the wall in frustration, noticing how even acting this way with his new voice just made him seem obscenely more butch than before.
He noticed hair was poking out of the top of his t-shirt, even, so embarrassing. He had to take stock of what had happened. He stripped off his shirt, angry and ashamed of the hair that had spread all across his chest and down his belly, so thick it almost spilled right into his hairy armpits. He scratched and felt the hair, all wiry and bristly where it should have been smooth. He pulled down his pants and his briefs and it was hair central and his meat flopped out, probably 9 inches and thick. "I don't want a fat dong" he thought.
He sat down on the couch naked. So upset. He picked up the jock, wondering how it could do this to him, and noticed the spot of cum that was still in it, wet. For some reason seeing that spot was playing tricks on his brain. He couldn't stop looking at it. This was the source of the curse; if only he knew how to reverse it. This wet, creamy spot. If only (lick it)... if only... he felt a strange impulse flow through him and shuddered. Why would he want to ... (lick)... NO!
Dave snapped himself out of it, moved his hand with the jock down towards the ground, letting it touch the floor, sweating and breathing in panic. What was... he didn't really understand himself, he had to reverse (smell it), he knew he wanted to smell what the spot was, he was curious, but he felt deeply that would lead to bad things and be a bad idea. Just toss it. He threw it in the corner away from him.
Oh fuck it, why be afraid? You're already a mess and don't have much to lose. You need to figure out the curse.
He stood up and went back and picked up the jock again, holding it up to the light a little. You don't have to do anything, just look at it and study it. It's not like you have to lick it.
Maybe if he could... 'oh, fuck it', he thought in a sudden impulse, 'what other ideas do you have? Do you have any?'
'You know you want to stick your face near that spot, smell that strap, find out if the strap is cursed, just find out''
...... Dave felt himself lose control as this dark, nagging bad idea took over. He knew it was wrong but felt flooded by elicit, forbidden excitement so he grabbed the strap with both hands and rubbed it all over his face. He gave in and licked the mesh and the cum spot with greed, breathing in the scent of it, then even as his big fat dick shot up into a hard erection, rubbing the jock strap all over his hairy chest, making nasty animal noises, gutteral to match a mind that had taken a turn towards the gutter. Yeah. He had to get this strap all over himself, see what happens. He rubbed it under his pits too, against his foot again, down his legs. See what happens.
"You're a fuckin jock pig" he said, feeling himself even get harder, if that were possible, as he said that. "Fuck yeah I'm a man, you fucks" he said and though he could feel himself blushing a bit shamefully with this behavior that was alien to him, it also felt good right along it. He practically tossed the jock strap back up towards his face and excitedly smelled and licked it sloppily some more, drool palpable on his lips.
