50-year-old Tomoyo Komatsu applies for a job at Public Slut Sensual Salon for the Masses out of financial need. During training, she receives rigorous instruction on techniques to maximize customer satisfaction, and soon begins enjoying sex with fellow staff members using her improved skills. Once she starts working at the shop, she lures passing men into her six-mat room with a seductive voice, flipping them over to lick their anuses, or letting them touch her feet while she massages their legs, relieving both their fatigue and sexual tension. For younger customers who remind her of her son, she provides body washes on the lewd chair followed by 69 blowjobs to bring them to climax. To regulars, she offers special treatment—rimming their ass holes as the ultimate in intimate, full-service pleasure.
