That JAV

I have been fast since I was a small child and was recommended to enter the track and field club, so there were high expectations for me in the club. Recently, I started dating Suzu-chan, a girl on the same track team, and it was smooth sailing.... However, one of my senpai (senior classmates) took an interest in me and started to discipline me. I was so hard on her that I agreed to a devil's bargain with her and ended up losing Suzu-chan, the most important girl in my life...
