Naughty Teacher gives lesson

This naughty teacher has a very important lesson which she will present to the whole class, their parents AND the principal. She's being tested on this so it can't go wrong..little does Miss Skye know, there is someone hiding under her desk trying to sabotage it. Miss Skye is determined to carry on despite the pleasures going on below the desk. Can she keep it together or will it be an orgasmic fuck up?
