Under the cloak of night, a horny stepsister can't resist her late-night urges. She sneaks into her brother's room, finding him asleep with his massive cock tenting his sheets. She can't help but stroke it, feeling it grow harder in her hand. Soon, she's mounting him, riding his thick shaft reverse cowgirl while he sleeps, her big tits bouncing. She grinds on him, her wet pussy gushing juice, until she squirts all over his cock and stomach, waking him up. He flips her over and fucks her hard, filling her with his creamy load.
