Teacher JOI - Caught during detention

You're stuck with your French teacher in detention - AGAIN. It's true, you're one of the toughest thug in this university (let's not question why college students would go to detention), you have smoked in the hallways, skipped numerous classes to drink, fuck, tag brickwalls. Detention has become a daily late-afternoon habit for you. But let's face it; you enjoy it best when Miss Collins monitors you. You're not especially fond of French classes, but you do like your teacher – and she knows it. The way she plays with her cleavage, showing half of her breasts and embroidered lingerie has you masturbating under the table; eventually, she notices! She tries to be mad at first, but then proceeds to teach you "how to use it properly" before the 20 remaining minutes of detention are over - a lot can happen in 20min! Follow her instructions and see what happens before the bell rings.
