My mother-in-law, Hiroka-san won a hot spring travel ticket in the lottery at the shopping district, and my parents-in-law and I will go on a hot spring trip.It was easy for her to just go on a hot spring trip, but her father-in-law, who was not blessed with her child, ordered her to live an ascetic life for the rest of her life.While traveling, I approached her wife while holding pressure from my father-in-law and a crotch that was about to explode, but I was just dodged.When I was spending a sleepless night in agony, I happened to witness her mother-in-law taking a bath.
