You are James (from POV vs Carol) and Kaylee is your girlfriend. Through a rather serendipitous series of events you both discover that you have had sexy boxing matches with Carol and Staci.
Kaylee wants another shot at a tournament and arranges one with Staci and Scott. The best the college kids can come up with is a cheap motel room and small ring. You're up first and find yourself standing across from Scott's bare chested girlfriend while both your significant others look on in anticipation.
