We met up with the slim and cute Yu-chan outdoors. She has a nice body that you can tell even through her clothes. We moved to a hotel with Yu-chan, who was embarrassed by the explanation of the erotic physical examination plan. We made her read out all the dirty words written in her sketchbook, and started by stripping naked. When she took off her clothes, we found her perfectly round beautiful breasts with a divine waistline! Her nipples and clit were pinched with a vernier caliper that can measure thickness, and she reacted sensitively! We wanted to see how excited she was, so we took her vaginal temperature after she came inside! So, please check out the video to see Yu-chan's measurements, sensitivity, vaginal temperature, and more, including her indescribably realistic expressions and smiles as her emotions fluctuate wildly during the monotonous examination and raw sex, as if she can't keep up with her emotions!
