Oh, that brings back memories. Not that story specifically, but his "The Barn" in "Again Dangerous Visions". Holy Hell, that might have been the first time I read flat out porn by a real writer. I think I got it at the school library too, probably Jr High.The one I remember is getting 'Biography of a Space Tyrant' by Piers Anthony out of the library. I don't think they'd quite realized the content, but it was the first time I'd read a book where I ended up realizing that the science-fiction was in service to the sex, rather than it being science-fiction with a mere sprinkling of sex on top.
Looking back, that book was all kinds of wrong and, no, definitely wouldn't be publishable here. I won't say any more.
