Married woman with erogenous zones and middle-aged oil masseur

Goro is a skilled masseur and skilled masseur who is well-known in neighborhood associations. Miki is her wife, whose sensitivity has increased abnormally shortly after giving birth. And then her husband Daisuke is on a business trip. One day, Goro gives an oil massage to Miki, who was exhausted from housework and childcare. There was no ulterior motives at all. I just wanted to relieve my fatigue. However, every time Goro's rationality begins to fade from the healthy treatment, he throbbed his body and let out a sigh of erogenous zones throughout his body.
