Sara-chan, with her fair skin, light brown hair, and slender erotic body, undergoes an erotic physical examination themed around 'the mechanism of a girl.' Even with the same theme, the change in examiner changes the atmosphere, which is also an example of this. First, Sara-chan is asked to read out loud the items written on the board: 'areola, nipple, vagina, clitoris, anus, vaginal temperature.' Sara-chan, following instructions, undergoes the measurements. After having an orgasm twice with a vibrator masturbation, she is remeasured to compare and discuss the temperature before and after the orgasm, predicting and experimenting with the temperature after sex during the experiment. The subject has a cute, doll-like appearance and modestly reacts in a very erotic way, which, except for that, makes it seem like a legitimate science research video. Feel free to use it as a topic of conversation in laboratories or academic conferences.
