Kyle stood there, intentionally going for not choosing, he was going to make her fix this with the dare.
"Oh, you didn't answer on purpose didn't you? Well before I tell you what your transformation is, for your dare, you'll never use the curse to change your transformation, or retaliate against me. Now.... give me a number, any number."
Kyle was pissed, where was she going with this, now he was stuck with these black bimbo legs, not thinking he gave her a number. "Eighteen."
"Eighteen??? Well aren't we greedy? For your transformation, your clit will change into a cock, with balls right underneath it, you'll keep that pussy of yours. And since you picked it, your new cock will be eighteen inches long! What an upgrade!" Jen laughed at him.
"You fucking bitch! This isn't what I wanted!" Kyle yelled at her.
"Okay, since you can't be grateful, your cock will be eighteen inches flaccid, we'll see just how huge it is when it's stiff. From this point forward, everyone will remember you as exactly how you are, and you'll never be able to convince anyone otherwise. You'll still be seen as male, of course, but everyone will know you have those lady parts. Oh I can't wait to see how your new hormones will change you! Maybe you'll be a pretty lady-boy! I wonder how big your tits will be!" Jen laughed. Kyle was shaking with rage, but there was nothing he could do about this now. He had the curse but he couldn't change his legs out for anything else, Jen for her part was still laughing as she walked away from him. One day he would get revenge, but for now, he had to deal with the growing monster in his briefs.
His new cock expanded, growing into existence, straining his briefs until he heard a loud tearing sound. He turned and started walking home, his now permanent problem made even more apparent by the extra familiar yet alien weight on his crotch. Still fuming he concentrated on trying to block out the sensations, but it was no use, halfway to his house he felt his cock go stiff, it lifted his skirt in front of him.
"Fucking bitch, I never wanted a cock this big, it's too fucking huge." Kyle muttered as he stared at his new burden, he would measure it when he got home, but for now, he had to deal with the distraction as his lower half swayed as if to mock him. All the while, Kyle thought about how to get his revenge.
