[Chinese]JUQ-458 While my wife was on a business trip, I was seduced by my sister-in-law Nao and had intense in-out sex for 30 days until I ran out of semen... Shinmiya Nao

I work at a company and currently live alone in this house. My wife, who is the breadwinner, travels frequently for business, and on her days off, she comes home to relieve stress by demanding sex, leaving me exhausted. My sister-in-law, Nao-san, seems to be concerned about me and often visits our home. I complained to her about having to abstain from sex for 30 days to have a child, but Nao-san gave me an inappropriate smile, touched my crotch, and whispered, 'If you can hold out, you can do whatever you want with me.'
