Natasha was feeling happy. She had officially been restocked on her formula that prevented her from transforming into a were-rabbit.
After a long day, she arrived back at her home. She was wearing a button up shirt, with a zipper jacket, skin tight blue jeans, and calve flat boots.
Natasha had been living her life normally, with her going on missions for S.H.I.E.L.D., and going about her day.
She arrived in her home, and hears her stomach growl.
"Huh, looks like I forgot to eat today," she said.
Natasha then heads to her refrigerator. She looks around, and gets a few carrots and some other assortments of vegetables. Only when they are all gone, does Natasha realize that she was behaving like the were-rabbit!
She looked at her calendar, and said, "Oh shit, that's today?!"
Every year, on the anniversary of when she became the were-rabbit, Natasha transforms for a full 24 hours, with her formula or not.
Natasha feels her whole body tingling a bit, and she hugs herself.
Natasha looks at her hands, and watch them morph into a pair of rabbit like paws with pads, and red fur.
She then feels her ears pop into floppy rabbit ears, and she grabs them, pulling them into her view.
"Oh god! Why now!?"
Natasha then feels her body bloating up, as her breasts shrink into her chest.
She started to feel something burning in her crotch! Natasha watched as her pants bulging, and her button pops off, and her zipper unzips! Her now giant 9 in long, 3 in thick dick sticks out, and Natasha can't retract it into her, no matter how hard she tries!
Natasha then felt her tail pop out of her ass, and rip out her seams. Black Widow then grew taller, and her shirt became untucked, and her stomach could be seen covered in fur, and Natasha was breathing heavily.
Her teeth then pop into bucked teeth, and Natasha's cock started to throb a bit.
Natasha's boots groan, and then burst open with her now giant rabbit feet coming out. She then felt an itch, and she scratched her ear with her foot, making the whole house shake! Her legs then gain mass, and rip out of her seams! Soon, her pants then rip apart, and Natasha then hunches over, and her jacket rips apart, as her shirt strains!
Natasha's face then bloated up, and her nose curled into a rabbit nose! Her body then bloated, and the buttons started to pop off.
The Were-Rabbit then rips the remains off, and roars! He then retracted it's cock, and ate all the vegetable remains out, before moving onto the fridge.
The beast eats all the leaves he can find, and leaves nothing behind. After a quick dig, it licks itself clean, and falls asleep in the burrow. There, it dreams of many things.
Soon, the rabbit wakes up, and runs through the town, and eats every bit of green it can find. Soon, it starts to mark territory, and other assortments that rabbits do. It even makes mess of things.
Next morning, Natasha woke up, and looks at herself. She gets dressed, and heads out to do her daily things.
"I hate that time," she said. If she was honest, she wished she had control over her transformations when she needed to get away from people, and in touch with nature.
Natasha didn't know what to do with her curse, but suppress it, and sometimes, even have some rabbit features appearing on her.
