Mike and Laura Noble
I wrote a story entitled "Taking my Spring Break in New England" about Mike Noble who discovers that his parents host swinging parties, involving his sister Laura, but excluding him. I've also posted a much shorter version entitled "I Forgot to Call", using a second pen-name. If anyone would like to try writing an alternative ending, or a short story using the characters or plot, I'd be delighted to have them included in this universe.
