[JUQ-415] I continued to make my wife's younger sister cum until she said, "I can't do it anymore," as she looked down on me for cheating on me. Rio Kuriyama (Censored)

Rio is asked to take care of her brother-in-law Ken while her near-term sister is in the hospital. However, when he happens to come across the scene of his affair... ``Any hole is fine! It's filthy!!'' Ken gets angry and curses at her, so he opens up to her, and to shut her up, he fucks her. Rio, who was humiliated by her scumbag brother-in-law, continues to resist, but she can't stand his caress as he persistently tortures her private parts over and over again, and yells, "I can't do it anymore! Stop!!"
