When Ai Mizushima walked through the office on her way to the manager's room, Ai thought she saw a man being serviced at his desk by a woman on her knees. The thought excited her- she has always been turned on by oral sex- and is so horny, she masturbates as quickly as she can in the waiting room. Hiking up her suit skirt, Ai rubs and fingers her dripping wet pussy, being careful not to make a mess of her clothes, or tear her back-seamed stockings.
