I find it surprising that most voters have voted for pillow humping - but many non-humpers probably don't even read this thread. Yet pillow humping seems to be more common - or less of a taboo - in the English speaking world than in continental Europe. However, for many people its seems to be only a substitute or a sex toy, not a real fetish as it is for me. At least commercial web sites have not recognised it as a fetish, because it is much easier to find diaper lover pages than any decent pillow humping stuff.
But I have recently found some interesting new stuff. If you search for "pillow" at pornotube and xtube, you can find some nice pillow humping clips, and a French woman called Bisou humps her bed and comforter at Gallerygalore - you should find them if you enter gallerygalore and pillow at Google web search.
But my pillow still gives me 2-3 superb orgasms every week. I actually consider myself lucky, because so many married couples complain sexual problems on web forums and so many singles are willing to pay big bucks for getting it. I paid less than ten euros for my present favourite pillow, and I have already had it for years, which means hundreds of orgasms and counting. It's filled with synthetic fiber called Fillwell, which is highly washable and retains its softness. Tonight I'm going to make sweet love to my pillow again, because I'm already getting horny...
