You’re trying to focus on homework when your busty stepsister catches you watching something you shouldn’t. She teases you, calling you a freak, but then gets curious—way too curious. When she finds out what kind of porn you’re into, her playful scolding turns into something hotter. She makes you pinky promise not to tell anyone, then admits she’s into the same taboo stuff. One thing leads to another, and soon her fingers are sliding under your shorts, proving she’s way more than just a stepsister.
