Rina's eyes gleam with mischief as she kneels before her student, ready to indulge in her fetish. She pulls down his briefs, revealing his thick, pulsing cock. She takes it in her hand, stroking it gently before guiding it to her waiting mouth. She licks, sucks, and moans, her enthusiasm building as she feels him swell. He holds her head, fucking her mouth until he can't hold back any longer. With a groan, he fills her mouth with his cum, and she swallows every drop, her special briefs soaked with her own arousal.
