Sam had been laughing to himself all day at school. He had been at a weird fair the night before but he didn't think much of it today oddly. As he walked out of class with his friends he came up with some good one liners about his friends haircut. For some reason he felt a deep burning on his right hand. He looked down and saw the entrance stamp from the fair. Weird, he thought to himself that it was weird that the mark had not washed off already.
What he did not notice was how he had been acting so sporadically and freaking out everyone else in school. Sam did not know yet but he was under a curse from the fair to turn into a creature based on his deepest desire to be a class clown. In the back of his head did know there was something wrong as he walked to the bathroom to take a piss. As he entered the bathroom two guys walked out, he went over to one of the urinals and unzipped his fly. He had not been horny at all today but the minute his average sized penis hit the air he instantly got a boner.
“Working hard or hardly working,” Sam joked to himself as he tried to pee now with a raging hard on. After trying to pee with no avail his right hand started to jerk off his cock with no warning.
“Woah, you gotta buy me dinner first,” he gasped as he felt a wave of pleasure. He knew he shouldn't be doing this but he just couldn't stop himself, his right hand seemed to have a mind of its own that's when he noticed it. The stamp on his hand, it was starting to glow a dull purple. Before he could think about anything else his cock spasmed and released load after load of sticky white cum onto the back of the urinal. His knees buckled from the ecstasy and he grabbed the divider to steady himself. What was going on, he had never jerked off at school nevertheless made himself cum in a public space.
“Well I guess the jig is up,” Sam heard a cheery voice in his head, “now you are under my curse.”
“What the hell are you doing to me,” Sam said aloud.
“Oh you will find out soon,” chirped back the voice. Sam felt himself become hard again this time he felt a burning in his right hand. The area around the mark began to turn a pale white covering his hand. He held his hand up and watched as his fingernails turned dark brown and pushed out into points. Scared, Sam rushed over to one of the two stalls. He put the lid down and locked the door. As he sat there trying to gather his thoughts he felt himself become hard again. What is going on, why have I been making all these bad jokes, and why am I so horny Sam asked himself.
