10MUSUME-082821_01 — How A Woman Works: Please Insert Your Penis Into My Tiny Vagina.

We thoroughly measure the sexy parts of the body of the cute, fair-skinned amateur girl, Koyama Izumi! She's not very charming at first, perhaps because she's nervous, but when she starts to feel good, she responds by letting out a loud "ahhhh!" This time, it's not fun to just measure her, so we'll compare her size before sex (normal) and during sex (excited). See for yourself how much the temperature inside her vagina changes after creampie compared to before sex!
