JUQ-897 Eng Sub. I can’t share with my husband that my father-in-law got me pregnant. It happened during a two-day, one-night trip to a hot spring where it happened multiple times.

Mary, a devoted daughter-in-law, faces constant pressure from her mother-in-law to conceive a grandchild and continue the family line. To boost her chances of pregnancy, the strict mother-in-law enforces a one-month abstinence rule—no sex allowed before an upcoming family hot spring trip.

On the day of departure, Mary’s husband refuses her advances, leaving her sexually frustrated. Meanwhile, her father-in-law faces similar rejection from his own wife. Both Mary and her father-in-law head to the hot spring to unwind and ease their tension.

In the steamy onsen, an unexpected moment occurs: the father-in-law catches a glimpse of Mary bathing, sparking uncontrollable desire. What begins as forbidden attraction quickly escalates into passionate, repeated encounters over the two-day, one-night trip. The story builds to a shocking climax—Mary becomes pregnant by her father-in-law, a secret she can never reveal to her husband.

This emotional and erotic tale explores themes of suppressed desires, family obligations, and irreversible consequences in a luxurious hot spring setting.
