Not my step sister, just a shy girl with a big ass

You've been eyeing your step sister's hot friend for a while now, but you've never acted on it. You've always been a good boy, respecting boundaries and all that. But when you finally get some alone time with her, you can't resist any longer. You're drawn to her big ass, her mature body, and her shy demeanor. She's not your step sister, she's just a hot milf with a big ass that you can't resist. You start by teasing her, touching her thigh, then her ass, feeling the warmth through her clothes. She's hesitant at first, but your touch ignites a fire in her. Soon, you're both lost in the heat of the moment, your hands exploring each other's bodies, your breath hitching as you get closer and closer. The climax is explosive, leaving you both breathless and satisfied. It's clear that this won't be the last time you'll be visiting your step sister's hot friend.
