Foursomes and moresomes!

Mark could sense an impasse here on the whole guy-gal thing, so he tried a compromise:

"How about a couple? That way, you get your extra guy and I get my extra girl."

"How about a couple of couples?" Jen replied with a grin.

Mark gaped at his hot young wife. She was flushed with excitement and her nipples poked stiffly against her nightie. This was the Jen that he had fallen for a few years back. But he had never dreamed that she had such desires within her.

"Two men and two women each?" Mark asked.

"They don't have to be mixed," Jen replied, "it could be a whole bunch of guys."

Mark looked unsure.

"You wouldn't have to do any gay stuff if you didn't want to," she added hastily, "I could give you a good cock sucking, whilst they took it in turns to fuck me. How does that sound?"

Mark found his cock hardening in spite of himself.

"Of course, it could be four women," he ventured.

"Hmmm, I suppose," Jen replied unenthusiastically, " Oh how are we going to decide!"

"I've got an idea," said Mark, "listen."

Jen listened intently.

"I can't hear anything, except some students returning from a night out," she said at length.

"Boys or girls?" asked Mark.

"I don't know, its too indistinct. Could be boys, could be girls, could be both."

"Then that's our random element," pronounced Mark, triumphantly, "why don't you go out and invite them in."

"What? Now?"

"No time like the present and I'm certainly horny."

"But, why me?"

"Because it was your idea. Also, if its a bunch of girls they're going to think I'm just some sad perv..."

"...which you are..."

"And if its a bunch of guys they're likely to punch my lights out for being queer. Also - and far more importantly - you look much hotter than I do."

And so it was that Jen found herself inching nervously out of the front door in just a skimpy nightie and a short dressing gown which she had insisted on wearing. She braced herself as the students came round the corner.
