I invited my in-laws on a hot spring trip to treat my father-in-law, who had suffered a leg injury, but my father-in-law, who wanted to see my grandson earlier, seemed to be viewing this trip as a trip for both my husband and I, rather than a trip to make a baby, so I felt a little pressured. I've been abstinent for a month as my father-in-law told me to, but after all, my wife gets her period... At that moment, I was left alone with my stepmother, and I couldn't control my rationality as my stepmother flushed cheeks and the white skin peeking out of my yukata.
