IPZZ-289 During the summer vacation, I, a virgin from the countryside, moved up to Tokyo... I couldn't keep my composure against the mature allure and unconscious seduction of my brother's girlfriend. For the three days my brother was on a business trip,

Dad, Mom... As expected, adult women in Tokyo are amazing in every way. Summer vacation... I visited my brother from our countryside hometown and came to the longed-for Tokyo... Unfortunately, my brother is on a business trip for four days... During that time, his girlfriend who lives with him will take care of me... Starting an unexpected mini cohabitation life with my brother's girlfriend!? Is she trying to seduce me in sexy clothes? Is it because she has the composure of an adult? Or does she let her guard down because I look just like my brother? She keeps unconsciously making bold, unaware advances right in front of me. Ah... I'm sorry, big bro, but... I really want to do something very lewd with this sister... Hmm~ I can give it to you, but keep your eyes closed, okay... Absolutely don't open them... I got too excited and went wild, sweating profusely as I pounded away over and over again... What!? You can't cum inside ahhhh!
