The Russian doctor, her eyes gleaming with kinky intent, welcomes her student into her private office. This isn't your typical lecture. She sits him down, her motherly figure oozing a sexual aura. "Today, we explore the art of self-pleasure," she purrs, pulling out a monstrous cock from her bag. She strokes it, her hands expert, her eyes locked onto his. "Masturbation isn't just for boys," she says, hiking up her skirt to reveal her panties damp with anticipation. She slides her fingers inside, demonstrating her point, her voice a sultry whisper as she guides him to touch himself.
