Sylvia's eyes widen as she realizes the true purpose of this 'special lesson.' Her sensei, a stern yet experienced warlock, guides her onto the desk, pushing up her skirt to reveal her plump, round ass. With a wave of his wand, he enchants a generous amount of lube, making Sylvia shiver as he spreads it along her virgin anus. He teases her, pushing a finger in and out, allowing Sylvia to feel the pleasure of anal penetration for the first time. As she moans, he uses his other hand to stroke her clit, bringing her to the brink of orgasm before finally pushing his thick, hard cock into her tight, virgin ass.
