In the dim light of the closet, siblings entwine, their bodies pressed tightly together. The brother's huge cock tents his pants, and his sister can't resist the allure of the forbidden fruit. She slips her hand inside, wrapping her fingers around his throbbing member. He groans, and she feels a rush of power and desire. She begins to stroke him, her touch becoming more confident as she explores his length and girth. He grinds against her, and she feels a wetness spreading between her thighs, her own need growing urgent. They're playing with fire, but they can't stop now.
