Sandra pressed the button twice on instinct while thinking of her two adorable pets. With the targets selected the Sex Machine started to work, and Stew found himself shifting a bit. His tail becoming less fluffy but he gained more control, his nails retracting into his paws, his entire genetic code to become that of a black cat like Stella. Sandra looked in shock as her little corgi turned into another cat, and for a moment the two cats looked at one another after taking their heads out of their food bowls. Staring at each other for a second they pounced on each other, and they seemed to wrestle for a second... and then Sandra got what was actually happening. While she had gotten the two neutered now Stew was fucking Stella!.. actually on second inspection the one being fucked was Stew? Sandra saw Stella's collar on the cat with a dick, and the girl cat being fucked had a rather loose dog collar on. Normally Sandra probably would've tried to separate the two, but in her mind she thought "You know... go ahead little furry buddies."
The two went on it for a minute and then orgasmed and stopped feeling content. A few seconds afterwards Stew started to grow back into the neutered corgi guy he normally was, and Stella's balls retracted back into her body as she became a girl again. The two seemed happy, but Sandra thought "...So... it's temporary and..." for the first time in awhile she could feel herself getting a little turned on "Do I dare use this on myself, and if I do who... or what do I dare use it on?"
