Beatrice Goldie, a religious woman, struggles with her carnal desires. One fateful night, her husband leaves for a business trip, and she's left alone with her stepson. Unable to resist her urges, she sneaks into his room, watching him sleep, his cock tenting the sheets. She can't help but touch it, and soon, she's sucking him off, her pious facade crumbling. He awakes, shocked, but she silences him with her mouth, mounting him, her pussy stretching to accommodate his thickness. She rides him, her body convulsing with pleasure, before they both collapse, spent and guilty.
