HND-612 Every time my older brother’s girlfriend comes over to stay, she secretly ties up inexperienced me and gives me a steamy first-time experience — Akari Mitani

My older brother’s girlfriend was incredibly beautiful, and whenever she came over, I secretly developed feelings for her. One day, my brother’s girlfriend tried to seduce me. Whispering closely in my ear, she said that while she liked my brother, their intimate life had become boring and asked if I would help her out. When she found out I was inexperienced, Akari-san got even more excited and ended up taking my first time, leading to a sudden, unprotected encounter. Day after day, I was swept into a series of intimate days with her.
