it's been 3 years since i started living with my father-in-law at my husband's parents' house. my relationship with my father-in-law is also good, and my marriage with my husband is harmonious, but there was only one thing i couldn't stand. i only have sex with my husband on the night of my ovulation for the sake of having children, but he cums before i can feel anything. moreover, my husband falls asleep looking satisfied, so my heart drifted apart with each act. and one night, while i was drinking water alone after the act, my father-in-law, who had woken up, pointed out that i wasn't satisfied with my marital relationship...
