A human couple meets an alien couple
So naturally, they decide it would be fun to swap partners. The alien woman goes off with the human man and the alien man goes off with the human woman. The alien man and human woman get undressed and he asks her, “Is it long enough?” She replies, “It could be a bit longer I suppose.” So the alien man slaps himself on the forehead a few times and it grows longer! Then he asks her, “Is it wide enough?” and again she says.
“I guess it could be just a bit wider.” So he starts tugging at his own
ears and it gets a bit wider.
An hour or so later the human couple get together to discuss. The man asks
the woman, “So how was your experience with the alien man? Be honest!”
She says “Honestly? No offense to you, but that was the single greatest
sexual experience of my life. What about you and the alien woman?”
The man replies, “Don’t get me wrong, it was good and all but she kept
slapping me in the head and pulling at.
