"We agreed, Melissa," echoes in her mind as she slips into her step-son's room, her pussy throbbing with taboo desire. She strips, her tattooed body clad in provocative lingerie, and sinks onto his bed. Spreading her legs, she touches herself, her fingers exploring her wet folds. She gasps, her body arching as she imagines him inside her, fucking her hard. The boundary between right and wrong blurs as she brings herself to a shuddering orgasm.
