When your riding teacher calls you into her office to tell you that you've flunked the class (again), you decide to teach her a lesson instead! You strip your instructor nude besides her riding bots, handcuffs, and a bit gag for that big mouth of hers. Then you teach her a lesson in riding she'll never forget! Finding the biggest cock in the stable you watch gleefully as she whimpers and stuffs her holes with thick stallion cock and winces at the pain of it stretching her wide. You make her lick the cock through her bit gag, tease her hairy pussy, and put on a show, satisfied that she'll think twice before ever criticizing a rider again...
