Accompanying her husband on his company trip, Fumika joins the party as the only woman. During the night's banquet, she's constantly sexually harassed by her drunk superiors—forced into tongue kisses, breast groping, and creampie sex under coercion. Gradually, other employees join in, performing double blowjob sessions and titty fucks, dressing her in micro lingerie and tormenting her with sex toys. Her body is slowly taken over, her tight depths squeezed again and again. Eventually, screaming "Deeper, deeper, it feels so good!", she reaches multiple orgasms in a pounding cowgirl position. Lost in pleasures she's never felt with her husband, Fumika completely falls into depravity.
