Kento is the most requested therapist at a male escort service for women, popular for his handsome face, tactful manner, and attentive touch. His true pride is his huge cock, which he secretly uses for forbidden full-service sex to secure repeat customers. Momoko, hiding her first booking from her husband, arrives tense and nervous. Even after the session starts she cannot relax—until one look at Kento's massive cock unleashes all her buried desire.
