Here's one MO-MDX
Sex on Mars
Mike and Maureen landed on Mars after accumulating enough frequent flier miles. They met a Martian couple and were talking about all sorts of things. Mike asked if Mars had a stock market, if they had laptop computers, and how they made money.
Finally, Maureen brought up the subject of sex. "Just how do you guys do it?" asked Maureen. The male Martian responded, "Pretty much the way you do."
A discussion ensued, and finally the couples decided to swap partners for the night.
Maureen and the male Martian went off to a bedroom where the Martian stripped. Maureen was disappointed to find that he had a teeny weenie member, about half an inch long and just a quarter inch thick. "I don't think this is going to work," said Maureen. "Why?" he asked. "What's the matter?" "Well," she replied, "it's just not long enough to reach me!"
"No problem," he said, and proceeded to slap his forehead with his palm. With each slap, his member grew until it was impressively long.
"Well," she said, "that's quite impressive, but it's still pretty narrow." "No problem," he said, and started pulling his ears.
With each pull, his member grew wider and wider.
"Wow!" she exclaimed. They fell into bed and made mad, passionate love.
The next day, the couples joined their normal partners and went their separate ways. As they walked along, Mike asked, "Well, was it any good?"
"I hate to say it," said Maureen, "but it was pretty wonderful. How about you?" "It was horrible," he replied. "All I got was a headache. She kept slapping my forehead and pulling my ears."
