[Reducing Mosaic]JUL-778 I couldn't tell my wife even if my mouth split open, I got her mother pregnant... During a one-night two-day hot spring trip, I kept forgetting myself and came inside. - Koizumi Rui

After getting married, he was invited by his estranged wife's parents to go on a hot spring trip. Officially, it is a family-friendly trip, but in reality, it is a child-making trip where his father-in-law ordered him to live an abstinent life for a month before the trip. Just by passing by my mother-in-law after taking a bath, it was the limit of patience that I got an erection. However, her wife is crazy about her hot spring and won't let her hold her at all. I ended up spending a frustrating night, and when I took a walk in the hall to calm my sexual desire, I happened to witness her mother-in-law taking a bath.
