I couldn't believe it, but she said yes and I finally got my first girlfriend! But then... Minami, my childhood friend who lives next door and is one year older than me, suddenly changes! I'm still a virgin for her... No! I got a girlfriend! But then I had my first experience at school...with my childhood friend's older sister...It was too stimulating...I couldn't get excited at all, even though I was longing to have sex with her!?
