As Jen gripped her own ass, she let out a startled gasp. Her ass was far too soft, and squished easily beneath her fingers, nearly oozing out of the spaces between her fingers. Not only that, but when she let go, she could feel her butt didn't UNsquish.
Jen rushed to the bathroom, craning her neck to look in the mirror. Sure enough, her handprint was clearly left in her ass, the flesh parted in the exact shape of her hand. Panicking, she grabbed the flesh again, trying to squeeze it back to a normal shape. To her surprise, it was much easier than she expected. Wherever she pushed with her fingers, her butt went back to normal, until it was smooth and round once more.
Now curious, Jen decided to experiment. With her index finger, she simply poked her ass, watching the entire time. Jen gasped again as her finger sunk deep into her own ass, all the way to the knuckle. When she pulled out her finger, the hole in her ass it had left was clearly visible. Puzzled, Jen pressed her hands to her butt again, feeling it mold and squish around her fingers easily. Her butt definitely felt way too soft, and the way it was acting, it was almost like clay of some kind. Her butt was totally malleable now.
Throwing caution to the wind, Jen squeezed hard with both hands, and watched as her butt flesh squished outwards. She let go, laughing at the weird shape her ass had been left in. Then, she realized, her cute little asshole had been covered up completely by her butt flesh. She dug apart the area where the puckered hole should have been, but could not find it, no matter how deep she dug.
Confused, Jen tried to do what she did before, smoothing her now-mangled clay butt into it's normal shape. However, even after she did so, her asshole was nowhere to be seen. Using her finger, she tried to poke the hole back herself. To her delight, it actually worked, and her asshole returned. Then, she thought to experiment again. She poked a hole in the side of her butt, thinking about making another asshole. To her surprise, her flesh did indeed turn into a second sphincter.
With another experiment, she pinched the other side of her ass, thinking about her nipples. Her eyes went wide as she watched the piece of flesh she pinched actually turn into a real nipple!
Jen was excited. The spray was amazing! She could transform her ass into anything she wanted! And... maybe it would work on other parts of her body?
