A slight snag.

Denzil Dexter, for that was the scientist's name gloated silently. At last his theories had been proven, the scorn heaped upon him by his colleagues would be avenged. The potential uses of his invention were staggering, if he chose he could contact the government and his invention could be used by agents to infiltrate terrorist and **** gangs. He could go commercial and be wealthy beyond his dreams, think how much rich, old people would pay to be transferred to a young body. He could franchise and have a worldwide network of body swap shops.

Denzil pressed the release for the straps holding him down and was momentarily surprised when nothing happened, then he remembered that the release button that he'd pressed into the young girl's hand was only a dummy meant to reassure her and allay her suspicions. As with many a mad genius Denzil was brilliant but absent minded and he had overlooked that after the swap he'd be wearing that body.

Denzil looked across to the other table, Mandy, in his body was blinking and staring about her. Her gaze came to rest on him and her mouth opened and her eyes bugged in surprise as she saw herself looking at her.

"Wh...wh...what have you done?" She stammered, then realised that she was talking with Denzil's voice.

Mandy pressed the release button and the straps disengaged, her hands flew to her face and she felt Denzils straggly beard and spectacles. She felt her unfamiliar male body, stopping in surprise as she reached the crotch. She undid her pants and pulled them open and stared in disbelief at the flaccid cock.

"Ahh, Mandy. Please try not to upset yourself." Denzil said. "I was perhaps not as honest as I should have been, but think of the breakthrough we have made."

Mandy stared at Dexter and he could see her face growing redder and a look of intense loathing.
