"I think everyone here is missing the truly shocking thing about this story: This female physical ed teacher is actually heterosexual!"
When I was in highschool, back in the last glacial epoch, a double gaited female physed teacher was boinking students of both sexes and got away with it for years. It only came to a stop when her oblivious hubby came home at the wrong time, the woman cried rape and hubby shot dead a horny teenage boy.
This sort of behavior is nothing new. But women do seem less discrete than they used to be.
"It only came to a stop when her oblivious hubby came home at the wrong time, the woman cried rape and hubby shot dead a horny teenage boy."
Moral of the story: Boink your married phys ed teacher somewhere other than her own home.
