ADN-775 I allowed my stepfather to insert it for just 10 seconds, but... our chemistry was so amazing that I came. - Rio Kuriyama

あらすじ

My father-in-law, whose wife had passed away, had lost his appetite. I told him to let me know if there was anything I could do to help, but... I never imagined things would turn out like this... "I want to insert it... inside Riho... just for 10 seconds! I told you I'd do anything, didn't I?"
