After completing a major project, he celebrates with his boss Rei before a sudden downpour forces them to shelter at her nearby home. Her soaked shirt turns transparent, and once inside she keeps tempting him—calling him into the bathroom while naked, pressing close in revealing lounge clothes, and showing off her voluptuous body. Finally she asks whether he wants to gain experience with her and guides his hand onto her breast. The wet-haired, sex-starved boss keeps him fucking until morning and gives him intimate creampie training all night. He returns to work already dreaming about their next sleepover.
