MIDE-817 Even though it was the first time I had a girlfriend, I lost my virginity to the sister living next door... Mihama Minami

I mustered up the courage of my life and confessed to my classmate, a humanities girl with excellent grades and a good personality. I couldn't believe it, but I got a girlfriend for the first time after receiving an OK reply! And yet... A childhood friend who lives in the house next door and one year older sister Minami changed suddenly! A virgin for her... No way! I got her! Nevertheless, I had my first experience with her at school... even though I had a girlfriend...with her childhood friend's older sister... Her stimulus is too strong...Even though it's my long-awaited sex with her...I can't get excited at all! ?
