Kenji was struggling with life alone for the first time after a long time of sending off his wife who had just returned home to give birth. When I was about to give up on the housework, Reiko, my daughter-in-law's sister, came to help me with the housework. Kenji, who was exhausted from the unfamiliarity, happily welcomed Reiko, but... Reiko's real target was Kenji's meat stick. I didn't know that, and I was completely erect without any way to make a bold chest and body touch.
