SDNI-005 - Active celebrity Takayama Sarasa, unable to hold back, hits her first full-nude climax on camera

It feels like watching an AV from the late 80s when they were still using VHS. There's just too much unnecessary clutter on screen. I don't see why they had to film the oral scenes like silhouettes, either. And the 'serious masturbation' scene mentioned on the jacket—where is it? I rewatched it several times, but I couldn't find anything that lived up to that claim. Are they referring to Chapter 6? If that's their 'serious masturbation,' then there are tons of scenes like that in Nikkatsu Roman Porno or V-Cinema. Plus, the camerawork is frustrating and just leaves the viewer stressed. It's true that it's unmasked hair-nude, but for an SOD production, this is just disappointing. What a waste.
