Yasuyuki was asked by his wifes friend Rina (Umi Hinata) to monitor the beauty treatment salon. - There, he was blamed for his sensitive nipples during the procedure, and he couldnt stand it and went out of control. - Rina, who was tickled by her so much reaction, played with his nipples again ... - Yasuyuki who writhes many times with the pleasure that his sexual feeling is relentlessly stimulated is led to further climax. - Unable to suppress his reason, he visited the beauty treatment salon where Rina works again while aching his nipples with the joy and expectation that will occur in the future.
