"Transform!" Jen blurted out.
"Good, good," Kyle started. "Well, considering the vile prank you played on me last wee-"
"Oh, when I pantsed you in the hall? That was hilarious!"
"-k - maybe for one of us it was, Jennifer, but not for me. As a consequence for your action, you'll grow-"
"Grow what, dweeb? A giant cock?" she teased.
"Well, yes, actually. You'll grow a horsecock, complete with balls, that is two feet long erect. It will reside in a sheath that extends up your torso, and when erect you'll titfuck yourself."
"What the fuck, you can't be serious!"
"Oh, but I am. In addition, you'll gain one, no, three inches in length each time you're mean to someone. Your sheath will grow accordingly until it reaches your chin, along with your balls. So don't be a dick."
"Har-har. Good thing this curse isn't real anyway, freak."
"Oh! That's three inches right there!" Kyle smirked.
"Yeah, right," Jen said, rolling her eyes and hanging up the phone. However, she was soon met with an intense burning sensation in her crotch. She doubled down, too in pain to scream. She watched in horror as her body changed before her very eyes; a monstrous cock began to form, a sheath quickly growing up her abdomen to hide it. In addition, large, pendulous balls formed below, resting on the ground. Soon the cock finished its growth, and spurted forward an extra three inches from calling Kyle a freak. She cried, wondering how everyone on the cheer team would react to seeing her massive sheath and balls at practice, along with how she'd get dressed without any fitting pants.
She decided to adorn a skirt to hide her new member, and walked downstairs. She could feel her cock stir in its sheath, and her balls slap against her thighs with every step. She wanted to cry, to get revenge on Kyle, but feared what reaction the curse would have to that. She quickly rushed past the kitchen to the door, and got on the bus, wondering how her life would change...
