Natasha was allowed to stay at Barton's farm, and the kids knew of her condition. They gave her space when the sun went down, and locked the doors. They did watch from the window, and hoped that she would stay safe.
Natasha was just relaxing on the porch, and she was thinking back to how she got her curse. She hated to think of it.
5 years ago...
Black Widow was fighting her way to turn off the switch. The crazy HYDRA agents were trying to make animal soldiers that could tackle any terrain. Natasha was assigned to stopping them, and she reached the switch to destroy the whole facility, but it was the wrong one. At the same time, the animal test subject was attached to the machine, and lightning struck the building. Widow and the bunny were both shocked, and the whole body of the bunny was transferred into Natasha. When Black Widow let go, she was knocked out cold.
When she came to, she found herself in a recovery room. Natasha heard something in the door. "The experiment worked. She is the first animal soldier." "Is there a way to cure her?" "No, we can only suppress it. She will transform into a giant rabbit every night at 8:00, the time the DNA was transferred into her body, but with a formula, we can block the transformation from happening, but it will only be temporary." There was a sigh, and the familiar voice of Nick Fury said, "Thank you doctor. Please make sure the formula is perfect." "I will sir. There are some test subjects who have been transformed themselves, and still have their human minds. We'll be sure to help them to cure Romanoff."
Natasha was freaking out. She would transform every night!? This had to be a joke. But she remembered the events that happened. Natasha then felt herself shaking. She looked at her phone, and saw the time, 8:00. "It's starting!" said Natasha. Black Widow looked in the mirror of her room, and watched buck teeth pop out. "Thon of a bith!" said Natasha with a lisp. She then lifted her hand up, and watched her ring finger retract into her hand as the stitching on her fingerless glove started to rip. Her hands and fingers then fattened, and she her glove ripped off, and she saw pads and fur growing on her now rabbit paw. She felt her other hand had followed.
Natasha's breathing was getting deeper, and her heart was racing. She was feeling very scared. "Whath happening to me?!" she asked, although, she knew very well, what was happening. In the mirror, Black Widow saw her nose curl into a bunny nose, and she was beyond scared right now. Her bracelets then popped off as she felt her back hunch over a bit, and her suit getting tight on her. She then felt a pain in her butt, and looked down to see something bulging out. The stitching ripped, and a cotton tail popped out. "HOLY SLITH!" Natasha's ears then got fuzzy, and she saw them in the mirror. Natasha then felt her woman hood burning up. She looked down, and saw a bulge in her crotch. The stitching them came undone, and she saw a huge cock sticking out! "WHATH FA FUCK!? WHY DO I HATH A COCK!?" She had little time to think about it, when she walked back a bit. She suddenly stopped, feeling her feet expanding. She looked at her boots, and saw her feet burst open as giant rabbit feet! Her legs then shifted into thick rabbit thighs, ripping her pants to shreds. She then felt her body growing red fur all over, and her face grew chubbier. Her ears moved to the top of her head, and popped into floppy rabbit ears. Her body then bloated up, and the zipper went down as she did, and her belts then popped off, the buckle getting lodged into the wall. Her hips then got wider, and the bikini bottom that was her pants ripped apart. Her panties and bra then snapped off, and flew into the wall.
The were-rabbit then ripped off the remains of the suit, and roared! He then retracted his genitals, and looked out to see the full moon. He howled while beating his chest. He tried to get out, but he was kept within the room. They dumped carrots, zucchinis, pumpkins, apples, oranges, and cabbage in there. Nick watched as the beast that was once Black Widow feasted on the fruits and vegetables. "One of my finest agents, and an Avenger, turned into a mindless vegetable eating machine because of HYDRA. Doc, make sure to get that formula working soon." "Yes sir!"
Present...
Natasha was pulled out of her thoughts, as she looked at the setting sun. She then got up to check on the kids. Cooper and Lila saw Natasha, and Lila asked, "Is it time for your transformation?" "Yes. You know what to do?" "Yes," said Cooper, "lock the doors, and let you in at morning, and give you a bathrobe." "Yes. Now, you need to get ready for bed. Just know, your parents will call to see if you're doing okay." Cooper and Lila hugged Natasha, and said, "We love you Aunt Nattie." "I love you too."
After the door was locked, Natasha walked to the barn to reveal all the vegetables that they had stockpiled for her if she ever stayed with them, just incase. Natasha felt her ears pop into the floppy rabbit ears. Natasha looked at the moon, and this time, it was full. She then looked at her hands, and watch them morph into fuzzy rabbit paws with pads! Natasha then looked at the barn door, and put a board up against the door to keep it closed. She turned around, and looked down at her feet. They burst out of her shoes, and Natasha said, "Good thing that they bought easily disposable cloths for me to wear." Natasha then felt her teeth starting to grow into bucked teeth, and her nose then curled into a rabbit nose. Her ears then moved to the top of her head, as it got chubbier. Her pussy then burned, and she watched the bulge coming in her yoga pants. The front then ripped, to reveal her human cock. She retracted it, and her tail popped out. Natasha then felt her body expanding. The stitching ripped apart, and her breasts disappeared into her body.
The were-rabbit got up, and looked at the vegetable pile. He then ate them all, and then burped loudly. He then looked to see a barrel of water. He then grabbed it, and drank it down. The were-rabbit then cleaned himself, and stretched. He then made a burrow in the ground, and fell asleep.
Next morning, Natasha woke up to see she was covered in dirt. She suddenly felt an urge to pee. She got up, and she suddenly felt an unwelcome appendage come out when she started to pee. She looked to see that her male part was still there, and retractable. "Oh, not this!" she said, as she finished, and pulled her dick in. There were times where she would have some were-rabbit parts still on her after she transformed. She looked her body all over, and saw she also still had a cotton tail. "This is going to be a hard one to explain," said Natasha
