ADN-505 It's been half a year since I had a relationship with my girlfriend's older sister. Whenever we meet, we always have sex with each other. Yuna Hasegawa

Now that I think about it, I may have been interested in 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 even stand there, 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 the older sister came out. Ah, I really like it. My thoughts changed to certainty.
