I work for a company and live alone in this house. My wife, who is the breadwinner, has a lot of business trips, and when she comes back on holidays, she is asked for her body as if to relieve stress, and she spends a tired life. Perhaps out of concern for me, my sister-in-law, Nao, often came to our house. - And I complained to Nao that I was forced to abstain for 30 days in order to make a child, but Nao touched my crotch with an inappropriate smile and whispered that if you can put up with it, you can like me too.
