Possible Trashy Book From the Early 70s

Pornography was not out in the open in the 70s in stores. But, I distinctly remember a paperback book with a photo of a bunch of hippies (I think it was all male) and they were running their hands all over a woman's body. I think they were all laughing. I was only 10 or 12 and always found the photo really strange (not so strange a few years later). I asked numerous AI, and my brother to help find the book. They came up with nothing.

This paperback was in all the shops that sold paperbacks and magazines.

Does anyone have a clue as to what book this was? It was a photo, not a drawing or illustration. I would have thought it would be easy to find. It's not. It's now going to have to come from someone who actually knows what book it is.
