Soft morning light filters through gauzy curtains onto the rumpled bed. Her slim legs straddle his hips, pussy sliding slow at first over his exposed cock. Brunette hair falls across her face as she leans in, kissing his neck while rocking harder — thighs flexing, breath quickening. He lies back shirtless, eyes closed, letting her take control in the quiet bedroom. She lifts up, then drops, gripping the sheets. Stepbrother's hands finally grip her waist mid-thrust, pulling her deeper into the rhythm until the mattress dips under them both.
