A young German woman, very skinny, curvy, 47-years-old, is giving a lecture at a university. She is standing behind a transparent PVC lectern. She is naked, wearing only a slightly button-up shirt tied at her navel, a very long man's black and white tie, tortoiseshell glasses, white ankle socks and black shoes. Her shirt, slightly unbuttoned at the top, reveals a glimpse of her cleavage. She is blonde, with short hair, cut in the style of the 1940s. She has blue eyes. The adults' students are looking at her, looking a little surprised. She has a delicate, childlike face. She has a smooth, shaved pussy. In the background, you can see a very large television showing beautiful nature.
