10musume-110219_01 — How A Woman Works: Her Nipples Stay Erect All The Time

Sarah, a slender, erotic girl with light skin and brown hair, is given a sexy physical examination on the theme of "How a Woman Works"! This is an example of how the same theme can change depending on who is doing the measuring. First, Sarah reads out loud the items written on the board: "areola, nipples, pussy, clit, anus, vaginal temperature." Sarah follows the instructions and is measured. After she cums twice with a vibrator, she is measured again to compare and consider the temperature before and after masturbation, and the temperature after sex is predicted, followed by experimental creampie sex. Other than the fact that the subject is a cute, doll-like woman of a certain age who reacts in a modest and erotic way, this is a science research video that you could easily claim is complete. It's also a good topic for conversation in laboratories and academic conferences.
