This female gym instructor is strict and will go to any lengths to teach his students in Female Gym Coach: Jump and Straddle (1981). Young women who wish to be gymnasts come to this coach because of the great results he gets. What they don’t know is that when they make a mistake he will strip them naked and use sex to teach them a lesson.

Sosaku Sasairi hooks up with a woman in his bedroom. They kiss passionately on his bed then he gets on top and thrusts away letting us get a good view of his tight ass. Later he ends up in bed with a very aggressive guy who pulls his underwear down and takes him from behind. Once again that tight ass is on display as it all goes down.
