"Pfft!" Tif said in disbelief, waving her hand a 'nonsense!' motion. "Yeah right. That's impossible and you know better than to try and convince me. You know I don't believe in that magical stuff."
"Oh, I'll convince you..." Said Missy. "You'll believe in wishes soon enough."
Before Tif could react, Missy sprayed Tif's legs, feet and groin. She then pinned Tif to the ground and massaged her legs.
"Hey!" Yelled Tif. "Stop that!"
Missy didn't answer, she was busy concentrating on her wish. She massaged Tif's legs, feet and even played with her pussy. Tif recognized that her friend would not stop and accepted the assault. In fact, she began enjoying it. Her struggles and grunts turned into moans of pleasure as Missy tweaked her clit. Lost in the pleasure, Tif failed to realize that her legs were melting together. Eventually, her pants could not take the pressure and longer and they burst. Slowly, she could not feel her separate legs, only a single appendage. Groaning, Tif still did not notice, even as her feet grew numb and joined into her single leg. Her new limb pointed at the end, looking like a snake tail. A numbing, cool sensation overtook Tif's tail as smooth, black and grey scales replaced skin. The front of her tail had lighter scales, like a snakes underside. She was now a snake from below the groin down. Tif felt strange. She was about to look when Missy used her left hand to massage Tif's breasts and flick her nipples through her shirt. Lastly, Tifs pussy appeared to close up and disappear. But Missy, whose finger was inside that pussy, knew that it was still there. A scaly skin flap had grown to cover the exposed pussy. Tif's vagina had become a slit in her smooth snake skin.
"My...my pussy...feels different." Panted Tif.
Before Missy could stop her, Tif looked down and immediately snapped out of her pleasurful stupor. She pushed Missy off of her and "stood" up. She witnessed the last of the transformation; her scales reaching her waist and stopping there. Tif was half snake.
"WHAT THE HELL?!" Screamed Tif.
"Believe in wishes now?" Said Missy, regretting nothing.
"I'm a freak!!" Sobbed Tif.
"I can probably change you back, don't worry." Said Missy. "I think it looks really cool, myself."
"PROBABLY?!?!" Yelled Tif in hysterics. "COOL?! IM A FREAKING SNAKE GIRL!! CHANGE ME BACK!!"
"Um..." Missy thought for a moment. "I bet we can. I mean, why would they make a thing like this and not include a reversal formula. But for now, I don't want you to change back. I like this snake form. And if you just let me spray the salve in some more places, you'll see that you can look even better, cooler, sexier!"
