I’ve just added “Muskrat Fun for Everyone” to my blog site under Story Archives. This story was first published by Playboy back in 1970. For some reason it was one of my most controversial publications with reader comments running from “Why publish this filth?” to “We need to know what it is”. You can find it by clicking on: http://www.standryer.com, clicking on Story Archives and selecting Muskrat Fun.
Enjoy the story, Stan
