[ENGLISH-SUBTITLE] ADN-505 I’ve been in a relationship with my girlfriend’s older sister for half a year. Whenever we meet, we always have sex with each other. Yuna Hasegawa

Now that I think about it, I may have been curious about her since the first time I was introduced to her (Akane). When I learned that today was my sister’s (Mayu’s) birthday, I couldn’t stand still, and before I knew it, I was in front of my sister’s house. When I rang the chime and there was no response, I was thinking of going home, but my sister came out. Ah, I really like it. My thoughts changed to certainty.
