At an exclusive membership gym in Minato Ward, beautiful female personal trainers offer one-on-one training sessions, making it a popular destination. A chubby male actor goes undercover to experience the service. From day one, the attractive thirtysomething and younger female trainers press their breasts against him, creating an atmosphere that feels like a sexual invitation. A new, ambitious twentysomething trainer visits his home, guiding him through squats while stripping off his workout gear. Pushing boundaries further, she even offers to "control his sperm," ultimately satisfying the client's sexual desires with her pussy—an erotic training experience like no other.
