“It feels funny.” Erika thought to herself as she entered her room. She closed the door behind her and hopped on her bed.
As she sat on her bed, the pressure became pleasure and she was knocked to her side on her sheets. She cried as her tail bone got longer and felt how it formed a bulge in her pink panties, forcing her skirt up. Then it began whipping around madly, shredding her underwear.
“Whats happening to meeee?”, she asked in between short breaths, sweating like crazy, as everything got hot, her heart pounding in her chest. One long minute she was thrashing on her bed, hugging her legs and curling her toes. Her hair got more and more messed up through her convulsing.
It ended slowly, her body calming down and she lay there, catching her breath.
When she saw what it was growing above her Behind, she regretted putting the potion on her butt.
A tail grew behind her!
She saw that it was as a little bit longer than her forearm, rounded and that it got smaller as it went to the triangle tip.
“Am I possessed by a demon?” she asked herself. It looked like a devil’s tail, but she heard no voices telling to “Go and sin!” or something like that, which disproves it in her mind.
She looked in her mirror and thought “Hey, it doesn’t look half bad!” and wiggled it left to right, amazed at her control over it.
She felt wetness between her legs, but paid it no mind while going to her drawer to replace her broken panties and choose a white one.
She hopes that her mother would understand that the new tail broke the one she wore before.
While doing that, she noticed that the tail felt amazing when her skirt rubbed it, so she returned to her bed, put her panty to side and put her right hand on her tail, rubbing it.
“Ohhh!” she moaned as a shot of delightful feelings got to her brain as she felt the smoothness of her addition, prompting her to mover hand faster intensifying the feeling. While she did that, her little bit tingled and she used her hand to message it, squirting the hand full of a liquid she did not recognize, leaving her squirming from two points of pleasure.
Then she felt so good, she yelled, her eyes closed and her legs shaking. More stuff shot out between her legs, dousing her left hand in it, while white stuff got all over her.
“It tastes weird.” she thought after some of it got into her mouth.
After it was she was exhausted and, without caring how wet her bed was, thanks to her, she put her head on her pillow.
She thought about her plans going onward.
