[FSDSS-078] I fucked my girlfriend Arina Hashimoto's older sister

FSDSS-078 I Tried Desperately. So Desperately. So So Desperately To Resist My Girlfriend is Elder Sister. I am a young man, I have a lover, she is very beautiful and gentle, not only that, she is also quite curvy. We were happily living together until Arina Hashimoto, my lover's older sister, appeared. From the first time we met, I was moved by her strange charm. Compared to my lover, she was half a pound, but she had an irresistible charm. I don't know why I'm like that, maybe I just have a preference for loving experienced people. I also had the feeling that Arina Hashimoto also liked me, and sure enough that night I couldn't resist her invitation so I... . After that night, I was no longer interested in my girlfriend.
