This is no longer on DMM/R18, not sure why. It's part of the Smartphone Project, where scenes from other JAV (so this does NOT include original content, but is rather like a special compilation) are taken and cropped to work in an portrait orientation. It's in SD, so a resolution of 404 horizontal, 720 vertical pixels.
As the title states, this is all about the handjobs, but since JAV rarely focusses on that exclusively, you get some other acts mixed in, especially blowjobs, but also a small amount of groping and titfucking.
