A group of doctors completely elucidate the developmental status of a beautiful girl in uniform, even down to the number of wrinkles in her anus! A special research project is being carried out in a certain school district. A pair of outgoing high school girls from a prestigious affiliated school arrive at the one-way mirror car venue. They reluctantly expose their skin in the hopes of receiving school grades, but... Nozomi sadly wets herself during a vaginal examination. Sumire protects her friend by saying, "Poor thing!", but when her nipples are played with, she writhes in agony, writhing her slender beauty body in agony. An introverted male student sneaks in and boldly peeks at their indecent behavior. Even though he's on the verge of a mental breakdown during the public urine test, the examination isn't even half over yet! The doctors' huge dicks repeatedly cum inside them, and the two of them cum over and over again while holding hands!
