Will's bratty little sister Madison just won't stop growing. She was a pathetic little four-foot-four as of her eighteenth birthday, and the least popular girl in school. Now that she's hit a late-in-life growth spurt, she's becoming even more of a pain in the ass to her older brother Will. Especially because she won't stop flashing her tits in his face.
Thankfully, Madison seems to have stopped growing just in time for their mom's business trip. They're only going to be alone for a week. What's the worst that could happen?
Head's up: this is a story about a sister and brother being mean to each other in creative ways, and having a lot of sex. There’s a ton of size change. Major themes include unapologetic incest, blackmail, shame play, BDSM, lactation / breastfeeding, and girls with penises. If you're not down for all that, kindly move along.
