JUL-348 My son is physically weak so I can help him reach climax

Three years have passed since I married my husband who almost ran away from home in Tokyo. This year, after receiving news of my mother-in-law's death, we decided to return to my parents-in-law's house because we were worried about my father-in-law being single. My father-in-law willingly accepted me, and I still lived the same life as when I lived with my husband, but the only problem was that my nightlife was extremely short. That day, after giving birth, I was masturbating in the bathroom to suppress the pain in my body when my father-in-law passed by and witnessed it. When I comforted him, he came closer.
