I'm dating Kyoko, a single mother. But the truth is that I'm not interested in Kyoko. I'm only interested in my daughter Rio. One day, I persuaded Kyoko to get married and had the opportunity to talk with Rio-chan alone. - Just as this time has finally come, she attacks Rio-chan. - Enjoy the perfect and feel the best until vaginal shot. However... It was a trap set up by a mother and daughter, and Kyoko secretly recorded a sex voice with Rio-chan. - I was forced to drink an aphrodisiac and was used as a meat vibrator for the rest of my life until the sexual desire of the mother and daughter was satisfied.
