The portio is the part of the cervix that extends into the vagina. It's the most sensitive area for sexual stimulation. Especially, 'Nozomi Ariumura' is incredibly sensitive compared to other actresses. If her G-spot is stimulated, she immediately reaches ecstasy. She's quite famous for this in the industry (among insiders). So, before the official filming, I thought I'd sneakily film her cervix reactions first. This is the video from this challenge. How did it turn out?! Of course, she has an amazingly sensitive constitution! Plus, once you start stimulating her cervix, Nozomi blows her load like crazy. Really, it splashes wildly and shoots out cum with incredible force. Since this was before the actual filming, there was a private atmosphere, so I definitely want to add that Nomiko was unusually 'serious' about her fucking!
