Kirsten Plant, the stern teacher, finds her student Zuzana Zed's curiosity piqued by the forbidden. They lock the classroom door, Zuzana eager to learn Kirsten's unique lesson. Kirsten, a veteran of VIPissy's piss play, instructs Zuzana to relieve herself onto her outstretched tongue. Zuzana, hesitant at first, warms to the task, her self-pee washing over Kirsten's face. Kirsten, aroused by the taboo act, fingers Zuzana's tight pussy, encouraging her to let go completely, their lesson in debauchery only just beginning.
