This group special exercising is a competition of two sports girls, both amateur and dreaming to impress their trainer. That's why they humiliate and tyrannize each other even more than the beefy male coach does, trying to find out who does the topless pushups, nude fitness situps, exercises for arms, tugging and backing better.
The submissive trainees even ride each other and serve like dogs so eagerly that the male trainer is ready to let them end up this special exercises lesson without any maledom sex workouts done. The nude sports girls just must rub their sweaty pussies till orgasm under his control. He will kiss the gymnast who comes first. Perhaps.
