There is a noise... Tracy comes to investigate.

“Luke? Are you out here? What happened in the back yard - oh my god! Who the hell are you!?” Tracy gasped as she stared at Luke in bewilderment.

“Wait, Trace, it’s me. Luke. I found this ... um ... alien device in the back yard and it changed me.” Luke explained fearfully.

“What? But you look just like me... except... are those horns and a tail?” Tracy approached. Whilst there facial features were the same Luke was clearly shorter and more curvaceous. She looked up at her wife and blushed furiously, trying to cover her nudity with her hands. Luke’s breasts were too large and sensitive and she felt hot and sweaty. “Why did you make yourself look like that?” Tracy prompted suspiciously.

“It was an accident.” Luke said, nodding at the display. “You put your hand there and then it reads your mind and the image forms. Then you use the purple button to open the door, enter and push the purple button again... and you change. I was just imagining stuff... I wasn’t thinking just testing it out.” Luke explained.

“And you like the idea of me as a cowgirl?” Tracy asked with a raised eyebrow.

Luke swallowed nervously and looked up at her. It felt odd to be shorter than her wife. “Um... Er...” Luke floundered.

Tracy smirked and put her hand on the panel. The image shifted and wavered to Luke’s body - but with horns, ears and tail matching Luke’s. Luke stares at the body as it grew more muscular and its manhood grew larger, balls oversized and hanging low. Luke felt an odd desire course through her new body.

Tracy watched Luke’s reaction and grinned knowingly. “You like him?” She asks.

Luke stared in mute lust. The strong female sexual urges were new to her. A brief mental skirmish was fought in Luke’s mind. His rational male half ordered him and to say no, protesting that this was weird at best. The cowgirl libido, enhanced by the mental adjustments, repelled that feeble attack and made its own thrust.

This body was the perfect match for hers, wasn't it? That cowboy... Luke’s mind disregarded its objections as she looked hopefully up at Tracy. “Yes...”
