Kitano Mina plays a part-time employee in love with her married manager. When reduced business hours leave him struggling and depressed, she stays after closing to comfort him. Alone together, she hugs and kisses him, but his concern for his wife sends her jealousy and lust soaring. Whispering that she can make him feel ten times better than his wife, she seduces him into sex, grinds against him until she loses control, and takes creampie after creampie as they drown in pleasure.
