After getting married, my wife's parents, who had been estranged, invited me to a hot spring trip. It's a trip without family water, but it's actually a child-making trip where his father-in-law ordered him to live abstinently for a month before the trip. Just passing by my mother-in-law after the bath was the limit of my patience so much that I got an erection. However, her wife is obsessed with her hot springs and never embraces her. Having spent a frustrating night, I happened to witness her mother-in-law taking a bath while taking a walk in the hall to calm her sexual desire.
