The coach is a dominate character while mine is submissive.
The coach is in his early 30ís and had been trying to find the right volley ball girl to fuck. Each night he would take a girl and figure out if she was willing or not. After practice the couch will take them to the gym room and just screw them from his office to the showers, the pool room, weight room and to the actual gym room.
Being that each year they win the champion ships the principle always turns his head against what the couch was doing. This year the coach has chosen a sophomore named Kate. She was skinny healthy had nice boobs not to big or small her but was not bad either. He knew at that moment when she tried out her freshmen year he would pick her. After Juliet graduated he went right to Kate.
This plot can go many ways...if you want we can change the sport as well it don't matter. This could go into maybe some bondage, rough sex, anything really!
