Cristi Ann, a big-breasted blonde bombshell, finds herself in detention, but her teacher has a different kind of lesson in mind. He binds her wrists and ankles, leaving her vulnerable and exposed. Cristi's hard nipples brush against the desk as she struggles, her pussy growing wet with anticipation. The teacher teases her, running a leather belt between her legs, causing her to moan and beg for more. He obliges, whipping her ass until it's a rosy red, then fucks her hard from behind, making Cristi cry out in both pain and pleasure.
