Tensions rise when a horny stepson, craving his busty stepsister, finds her studying in their shared room. He sneaks up, watching her big tits heaving as she reads. She notices him, but he's already hard, his thick cock tenting his shorts. He moves closer, she stutters, trying to resist. He drops his pants, revealing his massive cock, and she falters. She takes him in her mouth, her eyes watering as she struggles to accommodate his size. He fucks her face, his hands tangled in her hair, until he pulls out, rope after rope of hot cum landing on her face and tits.
