I bough this hug pillow cover at Comike this year. There were quite a number of them on display in the commercial booth area and actually a few people were selling them as doujinshi work. This one I liked the most. The character is the girl you see on DLSite. I haven't used the site myself, except to download background images for my work computer. (Feel free to download a few yourself.)
DLSite sells gal games, mostly. When it comes to gal games I'm a bit hesitant to start playing them. I worry a bit since they seem like cocaine or heroin to somebody's who is currently just an alcoholic. (I also would need to run Windows on my non-work Linux box.)
Experiences with the pillow: I'm a bit unhappy the pillow I found at Macy's wasn't quite long enough, so I'm thinking of stuffing the ends a bit more. It's also a bit large so it pretty much forms a wall in bed between me and my wife. This is unfortunate in many ways. But it's quite a bit more comfortable than her.
