What about a Short Story challenge leading up to the American Fourth of July?
(or for Canadians the 1st)?
Could be something patriotic but juicy, like the story of how Ben Franklin became a happy cuckold to some of his black slaves, and that is what led him to 'free them' because his wife insisted he do the work?
Could be something about a family that has been invited to a BBQ at their bosses house. What the dad didn't notice when he got the invite was this was a swinger's party and there would be clothing optional/open sex happening.
"Wow Dave, you brought your daughter and son? I had no idea you were that kinky. On Monday morning come to my office, let's talk about a more visible role for you at the office" says the boss as he stands naked in front of Dave and ogles his pretty wife and daughter.
Dave implores his wife to just play along. "We are here now. The kids have already seen Patty from accounting getting butt fucked. We may as well pretend this is totally normal"
or any of a thousand deviant stories your kinky little minds can cook up!
Please Note: If you are in another country and do not celebrate independence day, I can understand why you wouldn't care about the American Holiday but if you can write a story about aliens on another planet, you can write a story about some rednecks at the trailer park fucking and blowing up fireworks this Thursday.
What about a British person writing about two Americunts who are travelling abroad for 4th of July, and he reminds them they are technically subjects of the British Empire and disciplines them?
