[I can't believe my girlfriend's elegant sister was this erotic...!] I went to help my girlfriend move into the house she shares with her sister, as we were planning to live together before getting married... There, I met her sister, Kana-san, a gentle former announcer. I thought she was just a refined and beautiful woman, but while my girlfriend was away on a trip, she seduced me, saying, "Just for now, let's keep this our little secret, okay...?" Unable to resist, we had cheating raw creampie sex. Discovering our incredible chemistry, we spent the next morning with deep French kissing and raw creampies, gave each other blowjobs in the bath, and had continuous creampies in cowgirl position, our bodies entwined over and over... For three days, I drowned in the irresistible gap of this sister who transforms into a total slut the moment sex starts.
