The German teacher's saggy tits hang tantalizingly in her lacy bra as she bends over, inviting the student to fuck her from behind. He obliges, sliding his cock into her tight asshole, making her gasp. She looks back at him, her eyes filled with lust and a hint of pain, as he grabs her hips and slams into her. She reaches back, spreading her ass cheeks wider, encouraging him to go deeper. He obliges, fucking her hard, her tits bouncing with each thrust. She moans, her voice echoing in the classroom, as she feels his cock pulsing inside her, filling her ass with his hot cum.
