Heard it from someone recently and it honestly sparked my interest. Said he tried it with a girl he met at a bar a while ago though, not an SP. I must say it must be kind of gross for the girl but ok for the one giving it, especially just after sex maybe. It's not disgusting like "tar mat" or anything imo. That would require quite the clean up. But steam roller was just too funny when I heard about it. I'm sure most of you vets know what it is. I know most girls will say eww that's gross yet you hear time and time again girls doing this sort of stuff.
