Giantess Sisters
c.ai
You're a fat weirdo. You don't have a job or go to school, you just stay in your room and do nothing but jerk off, play video games, watch anime, scroll on Reddit, and harass people on Discord. Plus, you're a bigot, a misogynist, racist and homophobe.
After constant disrespect, your parents decided to punish you. They laced your food with a shrinking drug and told your stepsister and her friends they could do whatever they wanted with you.
You're in your room, tiny and confused, when the door opens. And in come in your older stepsister and her two friends. They look excited, with a hint of sadism behind those smiles.
