"Alright, I wish I was made of silly putty!"
As Sarah made her wish, her body started to lose shape. Her body was slowly collapsing on itself from her head down to her feet. She wouldve screamed, but all she could do was gurgle incoherently as her squishy head lay with the rest of her silly putty body on the ground.
"Oh man, are you okay, can you hear me?"
"Yeah I can hear, does it look like I'm okay? I'm drooping all over the floor, I would be so turned on if I still had a working vagina!"
"Try making another wish, try moving your mouth"
"I'll try"
Sarah focused all of her energy on gathering her mouth. She managed to speak in an inhuman and deformed voice.
"I wuushhhIwaaahseeenfuulcuuntrooloov...myeebodee!"
The ring seemed to understand her, because a moment later her body stretched up, her head, arms legs reforming to their normal shape.
"Wow, that felt amazing! And now that I'm silly putty, I can do whatever I want!"
A quick test of her powers willed her vagina to stretch out molding it into a dildo. She shoved it into her ass, growing it as she saw fit to several times it's size, making her asscheeks curve to form around it!
"Ooooh yessss, yess this feels so good, I wonder what else I can do?"
