As much as I knew that it was wrong it almost just made it more thrilling. The feeling that I could never let anyone know and that it was just our little secret. When I first met Natasha I had just gotten into a relationship with Mona. Two years later I was still with her and still fucking Natasha behind her back.

After the first night with Nat I thought things would change, that we would get together. I was wrong. She told me we couldn't date in fear of people finding out and using me to get to her, so we decided to keep in on the down low, a friends with benefits type of deal. I stayed with Mona for the relationship part but after a while I quickly realised Natasha was the only one who was able to satisfy me.

I sighed as Mona laid on my naked chest, drawing circles onto it mindlessly.

"That was great." she said with a tired smile.

I hummed in response and stared up at the ceiling, waiting for her to fall asleep. Once I heard her breathing even out I looked down and saw her fast asleep. I carefully took her off my chest and put her down on the bed, watching her snuggle into a pillow. I walked to the closet and put on some workout tights and a t-shirt with a light jacket on top. I put on my sneakers before grabbing my phone and headphones and walked out of the apartment.

It was late at night but being a shield agent I figured I could take care of myself. I hurried down the staircase and went out the door before beginning to jog down the street. I kept going until I reached my favourite park, where I now broke into a sprint. I felt my anxiety fade away as I ran and smiled as I enjoyed my favourite form of therapy.

After about an hour I decided it was time to head back but not before taking a quick glance at the giant Avengers tower.

"One quick visit won't hurt anybody..." I muttered before heading over.

I got into the lobby and entered the elevator, Jarvis immediately greeting me by name. The elevator took me up to Natasha's floor and I slowly walked out and looked around.

"Y/N, what a nice surprise." Natasha smirked as she walked out of her bedroom.

I nodded a little. "Trust me, this is a surprise for me as well."

"Yeah, last time you told me we couldn't do this any longer. What changed? Mona not able to fuck you right?"

I sighed and walked closer to her, gripping the collar of her shirt. "Shut up. You wanna fuck me or not?"

She scoffed a little before taking a tight hold of my throat. "You think you're gonna get anything by talking to me like that? Don't forget who's in charge, bunny."

I swallowed a little.

"Say it. Who's in charge?"

"...you, mommy."

She smiled. "That's right." she started to walk backwards into her bedroom, still holding onto my neck. "With you coming over unannounced I think the least you could do is be an obedient little girl."

I gave a small nod before I was thrown onto the bed. She crawled over me and pinned my hands next to my head before leaning down, brushing her lips against mine. "I'm gonna need you to say it."

"What?"

"Say you need me to fuck you."

I took a deep breath and tried to kiss her but she pulled her face away with a dark chuckle. I sighed and looked at her. "Please, I need you to fuck me."
