Summoning all the courage I had, I confessed to a classmate who was an excellent student and had a great personality. I couldn't believe it, but she said OK! I finally got a girlfriend! But then... My childhood friend who lives next door and is one year older, Minami-nee-san, suddenly changed! The virginity I saved for her... No way! I already have a girlfriend! Yet, my first time was at school... Even though I have a girlfriend... with my childhood friend's sister. It was too stimulating... Even though it was the long-awaited sex with her, I couldn't get excited at all!
