Natasha's POV
I got to the door and went to pick the lock, "I know you're out there." I heard a thick Russian accent say and I felt my hip burn but I ignored it, "I know you know I'm out here."
I got my gun out and went inside, "now are we going to talk like adults?" I asked and soon came gun to gun with the woman that resembles the little 6 year old I swore to protect. "Is that what we are?" I started to walk towards her, "put it down before I make you." Yelena said her accent still thick making me miss being around Russians her accent making me feel home.
Soon we fought both of us equally matched having been trained by the red room the exact same way. We were fighting until we were choking each other. I could see it was getting harder for her to breath, "truce." I spoke in Russian and we stopped attacking each other.
"You've grown up," I whispered in Russian. "No shit." We both got up and we were talking like normal people taking about the red serum until the roof exploded and then we were running for our lives until we ended up in a air vent in the subway tunnel.
"Great plan I loved almost bleeding to death," Yelena husked her voice as deep as her accent. "We might be here a while. Clint and I spend two weeks hiding up here." Yelena turned to me, "what is he your soulmate?" Yelena asked and I shook my head, "no I don't have a soulmate my mark is still black and white or last time I check it was but I gave up on that so many years ago. I've done to many things to get a soulmate."
"I have done the same does that mean I don't get a soulmate?" Yelena asked as she looked up at me. "You deserve a soulmate Yelena," I told her and she pulled me down on top of her. "Yel-"
I made a noise of surprise as Yelena's lips meet mine. Both my legs are either side of the person that used to be my little sister. I tried to pull back but Yelena just deepened the kiss her tongue swiping around my lower lip.
I opened my mouth slightly and that's all it took for Yelena's tongue to enter my mouth like she god damn owned me. I started to feel hot as Yelena took control of the kiss but oxygen is still needed so the blonde pulled away.
"Yelena what the hell," I looked down into dark green eyes. "It's about time for you to look at your soulmark," the assassin under me spoke well more like purred. I slowly lift my shirt up to see on my hip that the words 'I know you are out there' and the tattoo is now coloured in a bright green.
"How is that possible? We've know each other for longer then our tattoos should our first words be our actual first words?" Yelena softly traced over the tattoo causing me to shiver in pleasure.
"I think it's time I take control of my own action and do something I've wanted to do from the moment my tattoo burned," I looked down but soon it was me on my back and Yelena pressed into me. Her breasts pushed up against mine. Yelena's lips crashed against mine again and I let the heat consume me this time. I moaned and Yelena took control something no one as ever done with me before.
Not Steve, Not Bruce and Not Maria but it felt so good to hand the control over to someone I trust and who better to trust then my soulmate.
Yelena pulled back and started kissing down my jaw to my neck, "Natasha there is something I need to tell you." Yelena husked into my ear and I nod letting all the pleasure from the kisses on my neck to go right down adding to the heat.
"The red room-" I cut her off. "No talking about that just love me," the younger assassin just nod and started to remove our clothes piece by piece until she was in jeans and I was just in my panties. "Promise you won't leave me again," Yelena whispered into my ear and I shook my head, "I won't ever leave you again I promise."
Yelena pulled down her jeans and then her... her boxers? Just as they come down a cock flew up standing at full attention. My mouth watered at the sight of the huge 11 inch cock hanging off my little sister. "Can I explain now?" Yelena whispered and I shook my head and pulled her down, "I want that in me right now." Green eyes shoot up to mine and then a smirk made it's way onto Yelena's face, "magic words?"
"Please Yelena fuck me with your big cock fuck me like no one else can," I whispered into her ear and Yelena ripped my panties off me and lined up slammed all of the heavy meat inside me. "Fuck Yelena," I moaned and the blonde started to kiss down my neck.
"Please," I whimpered and Yelena pulled back and thrust back in slowly. I moaned feeling so full of Yelena's cock. "Are you ready to be fucked Natasha?" Yelena growled out in Russian and I moaned, "yes fuck me Yelena go wild and fuck me so hard I feel it for weeks."
The blonde pulled back and started to thrust into me fast and hard knocking moans and almost screams out of me but I quickly covered my mouth because we are still in a subway but that doesn't stop Yelena thrusting into me like a wild animal. I screamed into my hand as her cock reaches so deep inside me deeper then anyone else had ever gone.
Yelena got harder and faster and if we weren't both super soldiers I would've thought we'd break each other and my pussy walls squeezed down on Yelena's cock and she thrust do hard the air duct groans at the force.
Yelena started to thrust faster and harder until I was sure that I won't be walking straight and she moaned and lend her head in my neck, "I'm going to cum inside you Natasha. I'm going to cum inside your tight fucking pussy. I want you to cum with me okay." I whimpered nodding my head pleasure filling me up I can barely form a sentence longer then three words.
Yelena grabbed my legs and pushed then beside me making her go deeper inside me. "Here it cum," Yelena growled and thrust deeper then ever before and I screamed cumming as she shot ropes and ropes of cum inside me.
After I come down I looked up to see a very happy Yelena, "that was fun and I want to go to bed like that every night." I blushed as the blonde pulled out cum leaking out of me, "you know you'll never get me pregnant thought what if you want kids?" I whispered a bit scared and Yelena shook her head, "I don't want kids I love them don't get me wrong but I'd prefer a dog baby."
I smiled and hugged my soulmate, "perfect for you in every way remember." Yelena whispered and I remember Mama telling us that. "She was right but I don't think she'd be happy about us within hours of meeting each other again we fucked in an air duct in a subway." I whispered and Yelena pulled back, "probably not."
With that Yelena kissed me again and I felt at home for the first time since the Avengers split up.
