[FSDSS-497] In Her Absence, I banged Her Older Sister Yuko Ono, who loves cowgirl position for 3 days straight

Our good man Yuduzu has a very modest girlfriend, but he is committed to getting married soon.

But one day, he suddenly meets her bombshell sister Yuko, who is always horny, and everything changes completely.

During a 3 day break when Yudzuru was alone, Aoi self-invited herself to his apartment for a marathon of sex and girlfriend experience.
