A man visits a long-established hot spring inn and comes up with an innovative idea: calling a female massage therapist to his room to secure some private time alone with her. The therapist who arrives is a beautiful woman in her thirties, and she carefully massages the lymph nodes around his groin as per his request. During the session, his erect cock peeks out from the gap in his yukata, prompting the therapist to start stroking him off. Will this naturally lead to a sexual encounter between them?
