START-494 | I met a married man three months ago, and we had an affair with a man who absolutely forbids penetration. This is the first and last time we've had unlimited creampie sex, going beyond the limits of teasing. Yuna Ogura

"We promised that we wouldn't just have sex, right?" A secret relationship where they show each other how they masturbate... Onatomo and double infidelity. Penetration was supposed to be strictly prohibited... "I've only been masturbating, so it's probably not infidelity." The two continue to show each other how they masturbate over and over, and then their final passionate sex session. "Are you sure you want to do it? You'll never see each other again, you know?"
