With her husband away, busty brunette Lexi Luna finds herself alone with her stepson, the tension between them palpable. She starts innocently, asking him about his day, but her eyes keep drifting to his crotch. Unable to resist, she leans in, planting a soft kiss on his lips. He responds eagerly, their tongues intertwining as Lexi's hands explore his body. She unzips his pants, revealing his throbbing erection, and takes him into her mouth, her long hair falling around her shoulders. He groans as she sucks him, her expert tongue swirling around his shaft. They move to the bedroom, Lexi climbing on top of him in cowgirl position, her fake tits bouncing as she rides him. They switch to missionary, Lexi's long hair splaying out on the pillow as she moans, her pussy stretched around his thick cock. He flips her over, taking her from behind in doggy-style, her big boobs swaying with each thrust. Lexi can't help but scream in pleasure, their taboo family roleplay pushing them both to the edge.
