While filming a promotional video inside Tokyo's famous Red Dragon hostess club, the crew spots Reina Kuroki kissing a customer and letting him fondle her breasts near the restroom. She slips into a private stall and launches an impromptu shift as a devilishly seductive dominatrix. The chapters feature restroom seduction with oral sex and a titjob; secret sex at a table surrounded by other customers; an interview; first-person masturbation watching, oral, and a titjob with an employee in the changing room; and an after-hours finale packed with consecutive creampies.
