Yumi is the captain of the female track and field team, an athlete who has competed at the National Inter-High School Championships. One day, her father, who is also the advisor, gets injured during a training camp, and Yumi ends up coaching the track and field team in his place... The male team members, who have always held a grudge against their advisor, plot to make Yumi, who no longer has a backing, their daughter, their sex slave. They inject copious amounts of semen into the tight, firm pussy of this talented track and field girl! They have gangbang creampie sex over and over again until she gets pregnant! #ChinP
