Ren, a former gravure model and successful employee, is months away from marriage when she is ordered onto a business trip with the middle-aged boss whose harassment she cannot stand. With no vacant rooms, they are forced to share a hotel room, and he reveals that he has always wanted her huge J-cup tits. He roughly gropes, sucks, and slobbers over them before pounding her with a thick cock far more brutally than her fiancé does. Though she hates him, his relentless sex overwhelms her body and makes her cum against her will.
