Marty was close to the park so he decided to walk there, he would just head back to his car when it was time to pick up peter. he walked around enjoying the quiet nature sounds. kids playing at the park. a pair of hot female tennis players on the court, several beautiful girls were jogging, and... suddenly Marty's crotch grew hard as his cock slipped out of his waistband and up his shirt collar before poking out of his shirt collar. he quickly ran to the men's restroom and locked the door behind him before stripping.
he saw his cock spring to its usual 75-degree angle and proceeded to masturbate so it would go down. his mind was too hazy as he cumed to notice his cock splitting in two till he had 2 cocks side by side, a 9th testicle popped into his sack as he cumed. when he finally calmed down he saw his twin cocks and some thoughts hit him. 'i can double my sperm donation with these' and 'now I can have Gloria do an anal and pussy while kissing me' were some of them. he didn't even think that this should be an issue as he put on his clothes and headed outside.
he saw that there was still time so he headed for his car. he then drove to a Barbershop, and he went in and asked for a manly haircut. once the hair was cut Martha was no more, he was now Marty. he decided he liked being Marty, he now had money coming from the sperm bank, and he felt amazing and more outgoing. he didn't even care that he had more genitals then should be found on a man. as far as he was concerned they were his money makers.
