MIDE-817 Even though I had a girlfriend for the first time... Minami Hatsukawa lost her virginity after being eaten by the older sister living next door.

I summoned all my courage and confessed my feelings to my female classmate, a liberal arts student with excellent grades and a good personality. - I couldn't believe it, but it wasn't until I got an OK response that I got a girlfriend! - And yet... - Minami, my childhood friend who lives next door and is one year older than me, suddenly changes! - A virgin for her... - No! - I got a girlfriend! - However, I had my first experience at school...even though I had a girlfriend...with my childhood friend's older sister... - The stimulation is too strong...even though I'm having sex with my girlfriend...I can't get excited at all! - ?
