My childhood friend (RION), who I've always liked and wanted to date, and I were able to join the same club at the same university, and just as we were about to begin a fun campus life, an incident occurred. She has super huge breasts and has become a sex friend target for the chara and scary rear Mitsuru seniors. In the name of the tradition of the circle, I was made to do mud ●, and I took a strong ● POV! I tried to help her, but I was shocked when I saw her having sex with a senior, and at the same time, I got a strong erection.
