A young man, fueled by lust and a touch of resentment, discovers his step-mom's forgotten bikini. The silky fabric, still warm from her body, ignites his desire. He envisions her luscious curves, her tanned skin glistening with sweat, and his cock throbs in response. With a growl, he grips his fat, veiny cock, jerking it furiously. Precum leaks from the tip as he fantasizes about her in the bikini, her ass rubbing against his crotch. His orgasm approaches, and he decides to leave his mark, coating her bikini in his hot, sticky cum.
