In the dimly lit hallway, siblings whisper heated words, their bodies inches apart. Michelle's breath hitches as she feels her brother's throbbing erection against her thigh. Their eyes meet, a silent agreement passing between them. They slip into the nearby bedroom, hearts pounding. Michelle, dressed in a sheer negligee, exposes herself to her brother, who growls at the sight of her pert nipples and glistening slit. He captures her mouth in a hungry kiss, their tongues tangling. Michelle guides his hand to her wetness, moaning as he fingers her. They strip each other, their bodies pressed together, before he lifts her onto the bed, his thick cock poised at her entrance. They pause, a moment of hesitation, then Michelle nods, and he slides into her, filling her completely.
