I'm just an ordinary high school student. I finally mustered up the courage to confess to my favorite classmate, Kotone-chan, and she readily agreed. I was so lucky! I was so happy... She was an honor student who I could brag about to my mother, but she actually had a hidden side. She was having an affair with her PE teacher, who is 40 years older than her, and secretly gave him a blowjob at school. She also brought me, who she recently started dating, to her room and made me cum over and over again. We ran into her fourth boyfriend and had a duel sex session... When I asked her about it, she said she had had 10 boyfriends. It seems she was a natural slut who loved full-body licking... but I forgive her because she loves blowjobs, creampies, and swallowing, and she has a nice personality and is cute... me.
