At the elite Seishimizu Academy, the track and field coach employs a deviant "special training" method to improve his athletes' performance. He targets the talented American exchange student Mia Stewartson, convincing her that sexual stimulation is essential for increasing her speed and flexibility. As Mia quickly becomes addicted to the coach's methods, she joins the club president, Asuka, in a rivalry to become his ultimate tool for pleasure.
To boost the performance of Mia and Asuka, the coach implements his "Acme Athletics Theory," requiring the girls to abstain from orgasm for a week while wearing uniforms saturated with his semen. The experiment proves successful when the duo shatters national records at their tournament, resulting in a celebratory sexual reward and a sudden influx of new club applicants.
