Jen laughed to herself.
"Wh-what is it?" Kyle asked nervously. He swallowed.
"Well, I think I'll solve one of your many, many problems, twerp. You'll never get pantsed again if you can't wear any, right?"
Kyle's thoughts raced. What does she mean by that?? Images flashed through his mind of him attached to an animal, or without any legs, or any other number of disturbing forms. "C-correct," he spat out through his fear.
"Well, for your transformation, you'll only ever gain weight from the waist down. Maybe a bit of belly, a rounder face, some moobs if you ever get large enough, but over 95% of any fat you gain from now on will go straight to your hips and legs. You'll never be able to lose this weight, either."
Kyle thought to himself smugly, good thing I have a fast metabolism.
"To help you get bigger, your metabolism will slow to a crawl. Basically anything you eat will cause you to gain, hell, even water if it's got enough minerals in it. I know you're skinny because of it, I've seen what you eat. More than many of the football players, you weak twig. You'll also get even hungrier than you are now, basically never sated. Can't wait to see you pool out at lunch."
"Wh-what about my dare?"
"I dare you to lose all inhibitions about food. Stealing it from other people, eating anything put in front of you. You'll go from the class clown to the class pig. Table scraps, trash, cum, anything goes. You'll also be incredibly sensitive about your ass. If someone makes fun of it, you'll cry. If someone touches it, you'll scream at them, embarrassed. As you grow, you'll also be easily aroused by people touching it, so those screams may turn to moans if they keep going. Which they will, since it'll become a sort of... public stim toy. Free use to squeeze, smack, lay on, play with. You'll also start to go around without pants once you outgrow them. I dare you to not see any issue with being naked from the waist down, especially once your crotch is shrouded by fat. You'll wonder what all the fuss is about, why you keep getting in trouble for being naked, why all of the punishment is corporeal. You won't have a fucking clue, loser. See you at school, butt-boy."
The curse had taken effect immediately. Kyle wanted to cry. She called him 'butt-boy!' He looked over his shoulder at his ass. "It's not even that big!" he blubbered out, his stomach growling...
