SDMU-083 Schoolgirl vagina close-up health check. Vaginal opening wide open and clearly visible, feels it during the pelvic exam & sometimes penetration!

"Concerned about the effects of excessive dieting on growth due to nutritional imbalances in minors, we are conducting a development survey targeting female students in Tokyo." Using this as an excuse, they lure them into an examination vehicle and take close-up shots of the female students' vaginas! Depth, labia minora, wetness, endoscopy... every kind of examination is used to fiddle with the vagina! Furthermore, even male penis insertion into the spread vagina!?
