This is a valuable medical school lecture video. In the lectures, it is default for the students to learn from the actual bodies of the volunteers by observing their findings with their own eyes. This time, in a gynecology class, we are learning about membrane research using actual subjects. This woman will be taking the recommended exam next year, and apparently volunteer participation will earn her points, so she volunteered. The slits that are starting to grow are fresh, and while she is shy, she is exposed to the many participants with a pointing stick, which causes her to become "wet"! This is a vivid and matter-of-fact explanation, and there is no element of complacency in the instructor. The lecture was quiet and very serious. In addition, quite advanced research has been conducted on orgasms caused by caressing. Her nipples are also big. You can also make noise and be groped over there. fraction 10 minutes 25 seconds Video size 1920×1080 *This work is based on the terms of use, and does not contain content that does anything. *This is a normal photograph taken at an event where photography is permitted, and is not a **** work. *The subjects appearing in the photo are collaborators. *The content is fiction for the purpose of creating works. *All models are over 18 years old and their ages have been confirmed. ※**This is not data. ■Notes regarding products ●Video files can be viewed using video playback software.
