Eva Notty's maternal instincts take a decidedly carnal turn when she catches her stepdaughter Lilly Ford pleasuring herself in their shared bedroom. Lilly, dressed in revealing lingerie that accentuates her curves, is lost in her own world, her fingers stroking her soaking pussy lips as she imagines a lover's touch. Eva, drawn to the scene, can't help but join in. She kneels beside Lilly, her breath hot on her stepdaughter's ear as she whispers, "Let Mommy help you with that, sweetheart."
