A Russian MILF doctor captivates her audience with an explicit lecture on male sexuality, focusing on ejaculation. Using a large, realistic dildo, she demonstrates various masturbation techniques, stroking the toy with expert precision. She explains the importance of lubrication, grip, and rhythm, her petite hands working the tool with confidence. Her big, natural tits bounce slightly as she moves, adding a distracting yet alluring element to her lesson. The room is filled with the sound of her handjob and the occasional wet smack of her lips as she demonstrates oral techniques on the toy.
