While moving into her new home, prim office worker Miyu Aizawa is trapped with a respected senior colleague inside a sweltering room. An accident exposes the large stash of sex toys hidden in a box, and he taunts the seemingly serious Miyu into demonstrating them. With nowhere to escape, she initially resists in embarrassment, but the intense toys and his skilled caresses strip away her self-control. Soaked in sweat, Miyu finally gives in to her desires and begs him to creampie her.
