No

Natasha felt the nanobot water reaching ever higher across her body. It passed over her knees, then her thighs. Eventually her hips, torso, shoulders and head were all submerged. She could feel it, but she couldn’t move. It took the absolute last of her strength to drop the remote. She had nothing left. She surrendered herself and waited for her inevitable transformation.

It all happened slowly, but she could feel her muscles shrinking. Steadily the memory of fighting, sparring, working out, killing and being repeatedly injured all faded from her mind. Her legs and arms stayed toned, and well exercised, but years of mixed martial arts training and dynamic acrobatics were replaced in an instant with memories of yoga and aerobics. In less than ten minutes she went from being the deadliest woman on earth to having the body of a housewife.

But that wasn’t enough for Petra. Her wife needed to be more than some common Stepford.

With Natasha barely noticing, her hips widened even further, as her ass got even thicker, and her pelvis widened for birthing and fun times. Tissue that had been muscle became fat and moved to her bride’s ass and tits, giving her a body any woman would dream of or envy. When the existing tissue was all used and relocated, Petra had more added by the nano-bots, giving her betrothed the shocking measurements of 96/62/89. At the same time, Petra’s machine restructured her muscles and vertebrae so that her dearest would never have a sore back from her enviable rack.

As Natasha felt her memories of her old life slipping away in the tank of nano-bot infested water, Petra had one last thing to fix. The Black Widows were all robbed of their abilities to have families. That just wouldn’t do. Petra wanted her and her bride to have a beautiful family. So the bots began to enter Natasha’s most sensitive place, and reconstruct it cell by cell. Of course a change needed to happen. Neither she or Petra had the correct tools to conceive life in the other. For now.

The bots changed that as well too, altering her eggs and reproductive cycle. From now on, at any moment Petra and Natasha both wished, if they had sex during her cycle, it would give them a beautiful daughter. A baby girl perfectly engineered to reduce sickness, stronger bones, and a powerful mind. She would have the duration of her pregnancies cut in half, and her daughters would always be perfectly born, so as not to scar Natasha’s beautiful tummy.

Years faded away from Natasha’s mind and body. The healthy but still aged woman had actual years of existence reversed on her organs, body, mind and brain. The woman previously in her late forties shrank slightly as she was turned into an outward and inward twenty-year old. Her memories were replaced as though she was only a college girl. Everything about her was restored to her youthful prime.

The entire transformation was done in minutes, turning Natasha from the world’s deadliest assassin into Natalie, the doting perfectly built bride. A bride who would give Petra and her daughters every kindness. A wife who’d never be sick, and would only get angry in acts of absolute self defense. She had enough muscles left to handle that, Petra believed.

With one last button, Natalie’s paralytic was wholly purged from her system, and the water drained from the tank.
