Yasuyuki was asked by his wife's friend, Rina (Hinata Umi), to monitor her esthetic salon. There, he was accused of sensitive nipples during the procedure, and he couldn't stand it and exploded. Rina, who was tickled by her reaction, played with his nipples again. Yasuyuki, who writhes over and over again with the pleasure of being relentlessly stimulated by his sexuality, is led to further climaxes. Unable to suppress his reason, he visits Rina's working esthetic again while making his nipples tingle with the joy and expectations that will arise from now on.
