I was the only virgin in my class, so I was worried, depressed, my grades were dropping, and I refused to go to school! A super kind older sister noticed something was wrong with me and comforted me! She became my first sex partner! At first, I was just moving my hips as I was told, but it felt so good that I started thrusting with all my might! Then I inserted it! I broke my promise to do it... but as a result, I made the boys in my class 10 levels more slutty! *This work is a selection of one person from the already released "HUNTB-445".
