Isekai into Marvel/DC

Natasha shuddered again before rolling off to catch her breath. She was drenched in sweat. The room had already become muggy from constant activity, and she felt tired and sore for the first time in a long time. It was a good soreness. It made her feel like she accomplished a difficult mission. Something felt different about her after that last time, and the man she had started to grow feelings for followed her before placing a hand on her stomach.

He had his brows furrowed as if in deep concentration and his eyelashes fluttered as if he had almost passed out. After doing whatever he had done, he looked into her eyes and gave Black Widow that cocksure grin before leaning in to kiss her. “That’ll just about do it for you. Now I only have to make the circle and core for you.”

Wait. Wasn’t that what he was just doing? She was about to ask him, but he told her to take the lotus position, and we had to move to the floor because the soaked bed was too distracting for her to focus. The moment the core was formed she felt like for her entire life she was only allowed to walk, but now she could run.

She felt more. Just more of herself than she had ever felt before. Like a sudden recovery from the flu, all of her senses were shooting off at a higher capacity than before. She could feel the changes in her body and something was off. She always had an empty hollow feeling that she’d grown accustomed to over her life, but it wasn’t there.

She focused solely on it and couldn’t feel it. Besides that, the sudden gush of blood leaking from her was a shock she couldn’t comprehend. Her brain shut off and had to reboot as she couldn’t understand what was happening. Did he hurt her at some point, and she didn’t remember? He must have noticed her confusion because he finally spoke. “I regrew your womb. You can have children again.”

I did a bad thing, but it would work out in the long run. I’d normally have to ask for permission to change someone, but if I were to subtly ask her a question while she was screaming, “YES GOD YES YES YES!” it counted as her giving me permission. Another bad thing I did was check her mental condition with diagnostic touch.

She was mostly fine, but she did have a huge glowing problem I could take care of. Her maternal instincts were cranked up to 11. It was giving her low-grade depression that she could never have a child, and some mental disorders all stemming from that problem. To put it into perspective, a five would be what most normal people would be at. 

A one you had no instinct to protect children, and even some hatred towards them. A three, you would help a child if it didn’t cause you too much trouble. Five, you would sacrifice your own life to protect your own child's life. Seven you would sacrifice your life for a relative's child. Now eleven, eleven meant you would sacrifice your life to save an unknown child from suffering.

It wasn’t a very easy job either. I couldn’t do it all at once, and it took most of the day and almost all of my stored biomass to pull off. I made an extremely small version of her womb, which took most of the biomass. Just creating a tiny version took two hundred by itself. Slowly expanding it to a normal size, then attaching everything and making sure it worked almost knocked me out.

The expected smile of happiness didn’t come. Instead, I was greeted by deep whaling sobs I would have never expected from the Black Widow. I watched stunned for a few minutes before I realized she would be crying like this until she calmed down. I left and got a washcloth before wiping her down. Reconnecting her womb made her body spray blood everywhere, so I cleaned that up and off the floor.

I started to get redressed before she grabbed my shirt from behind. I led her back to the bed, and we just cuddled for about an hour until she finally calmed down enough to speak. “Thank you.” It came out as almost a squeak. “Thank you. Thank you. Thank you.” She started crying again, as she kissed me in between the thank you's. 

I thought her having the chance to have a child would lessen her instinct, but it only made it go up. It was almost breaking into the twelve range which would be otherworldly levels of love for children. The matron gods were ranked twelve as they treated all their followers as their children and would wage wars and destroy planets if any were even harmed.

There was nothing I could do about it now. I think I made a mistake not telling her beforehand, but I didn’t want to get her hopes up. I wasn’t even sure I could regrow her womb in one sitting, even with a thousand biomass stored up. If I didn’t break through to the second rank from the middle rank, then it wouldn't have been possible.

The amount of shit I could do now in comparison to before was staggering. Recovering a body part was just having enough biomass as the actual part that needed to be replaced. Helping someone was about one hundred percent easier, and I felt like the biomass I could suck from a single person had gone up to a hundred at once.

I would have only gotten maybe ten percent done, but the sudden boost barely made it possible. I just let her cry on me for a long time as she stared deep into my eyes. I asked her. “So you want to start making babies now or do you have to prepare for them first?” The deer in the headlights looked at my question and let me know, she hadn’t thought of when to have children yet, only that she could.
