John took the device in his hand. "I'm going to try something else" he said.
Outside it was dark. There weren't many people about, so John and Frank walked down the street. Round the corner from Frank's house was a small area which contained a number of shops, a pub, and a club. A girl was coming out of the club, drunk, with her boyfriend - or at least, someone who she had picked up inside. The man was obviously hoping for something more, as he kept putting his hand on the ladies rear.
"What are you going to do, then?" said Frank.
John held the device and pointed it at the woman and pressed the blue button.
"So," said Frank, also holding the device, "Who are you going to swap her with, then?"
John turned to Frank and looked him in the face. "You" he said, and pressed the button again.
"What the hell man!?" said Frank, stumbling backward in surprise. Noticing an unfamiliar hugging feeling, Frank looked down at himself.
His vision was greeted by the generous cleavage of two perky breasts, inside a tight black mini-dress.
"The fuck dude!" he stuttered, taking a wobbly step toward John. Feeling the black tights on his legs shift, and hearing the clack of the girls heels.
John ignored Frank's protests and pointed to the girl and her boyfriend. Her head now on Frank's body, his baggy jeans and scruffy faded-red polo shirt, the boyfriend's hand still cupping, what technically was Frank's, butt.
