This guy is engaged to Akari Tsumugi and he is living with her, on the premise that he will get married soon.
One day, the unimaginable happens, when Akari meets her husband's best friend and he is on top of her, with lewd proposals. She didn't want to cheat on her husband, so in order to offend her friend, she asked him to do a quick toilet. Because according to her logic, a blowjob is not cheating.
But that guy didn't stop trying and he didn't give up, and after 3 blows in a row, she gave herself up on creampie sex.
The funny thing is that some people in Japan also think that having sex with a prostitute is not adultery... lol.
