Maruta W, the uptight office matron, finds herself in a compromising position with her willing underling, Maruta H, during a company outing. As the sun sets and the booze flows, Maruta W's inhibitions evaporate, and she turns into a dominant, lewd seductress. She teases and torments Maruta H with her words and body, making him pleasure her until he cums, then denying him release. She commands him to watch as she fingers herself, then rides him reverse cowgirl, taking his creamy load deep inside her hungry cunt, leaving him cuckolded and craving more of her brutal, taboo love.
