I Can Never Tell My Wife… I Got My Mother-in-Law Pregnant… - I Lost Control and Came Inside Her Over and Over on a One-Night, Two-Day Hot Spring Trip - Hatsune Minori
The family of four goes on a hot spring trip, but the husband is forced into a month-long period of abstinence before the journey after his father-in-law urges them to conceive a child. His wife and mother-in-law are die-hard fans of the hot spring idol group "Sokkatsu Onpu," and become completely absorbed in their performance at the resort. On the day of the trip, the wife is so engrossed in the idol show that she completely ignores her husband. Left sexually frustrated, he wanders the inn at night and accidentally stumbles upon his stepmother while she's bathing... A night filled with warmth and tension begins.
