Marvel One Shots

Pierto x Sierra

****WARNING!! This chapter has strong sexual themes, you've been warned!!****

"FUCK!" I yell out as my body collides with the training room floor. Steve stands above me, still in his fighting stance

"You told me not to take it easy on you Sierra." He shrugs, panting. I groan as I roll onto my side, pain shooting throughout my entire body

"I know but I thought we were working on MY training today, not yours." I groan, rolling over onto my stomach and slowly stretching myself out. I hear him chuckle and remove the tape from his hands

"I'll see you tomorrow Sierra. We'll try again." He chuckles and jumps out of the training ring

I groan again and bring my knees to my chest so my ass was in the air, stretching my spine. My knee pads squeaked against the mat as I did so. I place my hands under my forehead and relax the best I could. Man I was sweating my ass off and I'm only wearing a black tank top with black volleyball shorts. How could I be sweating this much? Oh, wait. I know.

Damn Steve and his super soldier strength. All I can do is set things on fire. I remember when I practiced with Pietro a long time ago. He ran around me in circles cutting off the oxygen I needed for the fire, and to breathe. Fury came in and stopped him just as I was fainting. Sure it was terrifying but, that's part of training. We trained a few more times after that, then we learned each other's tricks and got new partners

Suddenly a flash of blue, a gust of wind and a shooting pain went by/through me. I yelled out in pain and grabbed my ass cheek rolling over onto my back, ignoring the pain there as well. Tears formed in my eyes as it felt like someone had taken a hot iron and pressed it against my butt and punched my spine with brass knuckles. A string of curse words escaped my lips. Then, I let out the loudest groan that turned into a scream. I'm really glad no one was around for that. But no tears will be shed today. I covered my eyes with the palms of my hands and took deep breathes until the pain in my ass subsided, which took about 10 minutes

"You didn't see that coming?" I hear the familiar sexy Sokovian accent I've learned to love so much. Then it hits me. He hit me

"You're dead Maximoff." I groan and look over at him. He's wearing black joggers and his usual two toned grey and blue shirt. A hint of a flirty smile on his face. How cute. A ring of fire surrounds us in seconds, I use the opportunity of his distraction to stand up and remove my knee pads. Pain fills my entire body but I ignore it

The circle of fire becomes smaller, forcing him to get up onto the training mat with me. He looks all around him, debating on either what to do or what to say. I expand the fire to make it a thicker ring around us in case he decides to run, he'll burn alive before he reaches the door. He looks almost scared. Good. I'm not going to kill him though

"Paybacks a bitch and you're a pain in my ass Pietro." I look him up and down, figuring out my next move. Sweat begins to form on his forehead as the temperature in the room shoots through the roof

"So am I." He cocks a smile and takes his usual fighting stance. I smirk and let the fire engulf my hands in big rings, swirling around my wrists and palms

I chuckle, "I know, I have a mark to prove it." He chuckles as well

"I had to, it was RIGHT there in front of me." He points to my butt and starts to laugh. I relax my muscles a bit as his laugh is contagious, soon I start to giggle. The flames around us die down until it's nothing but steam. I comb my brown hair back with my hand that's now not on fire and sigh

"But did you have to be running when you did it? I'm going to have a major bruise now for months." I watch him as he walks towards me smiling. Then in a flash of blue, I'm being held in his arms and being dipped as if we were dancing

I laugh and look at him as he gently places his hand on my sore ass cheek, "I claimed it then." He states simply. I throw my head back and laugh some more

"Everyone knows I'm yours P. Nothing's gonna change that." I sigh closing my eyes. I feel his lips on my exposed neck and resist the urge to push his face away and hide my neck like a turtle

"You're so hot.." He speaks against my throat. I raise one of my hands, setting it ablaze

"Oh really? I never knew!" I speak sarcastically. He chuckles, picking me up bridal style. Once again I see a flash of blue, feel a gush of air and suddenly we're in my room. He closes the door behind us as I sit down on my computer desk. "You know, you bring a new term to 'pain in the ass' P." I lay down on my desk as he stands between my legs. He places a hand on each of my knees, sliding them up to my hips before leaning down and kissing my stomach

"Yes, but I am YOUR pain in the ass Sierra." He chuckles before trailing kisses up my stomach until he reaches my lips, stopping briefly to bite my breast through my shirt. How did I get to be so lucky

I smiled against him and slid my hand down his perfectly chiseled abs till I got to his hips. "I don't like that kind of pain." I speak seductively against his lips. He smirks and in a millisecond, I'm face down on my bed with my ass in the air, Pietro directly behind me. He leans over my body, pressing his erection against my butt and kissing my shoulder blade. I almost moaned as he rubbed his erection against me

"What kind of pain do you like then..?" He whispers seductively in my ear, sending shivers throughout my body. I can't even see him but I know he's smirking with an arched brow all sexy like. I let out a small moan as he rubbed against me again

"You know the kind I like babe," I wiggle my butt against him, biting my lip as I looked over my shoulder at him. He looked at the clock on my wall briefly

"Quick one?" He asks hopefully. I smile and slide my volleyball shorts to my knees as he maneuvers his rock hard erection out of his joggers

He rubs himself up and down me in a teasing manner before sliding the tip in. He repeated that, knowing it helps bring me to orgasm quicker. Then, without warning, he slams his entire cock in me. My yelp/gasp got muffled in my pillows and sheet thankfully. Pleasure ripped through my entire body as he repeated the motions

"Pietro," I begin, looking over my shoulder at him. He looks up at me with that sexy look of his. "Hurry." I state. He nods, understanding our secret message as I remove hair from my face. He smirked and grabbed my hips tightly before slamming into me repeatedly at almost his full running speed. I moaned and almost screamed in pleasure as he pounded me from behind

Sure enough, within minutes I feel the familiar feeling in the pit of my stomach and my walls begin to tighten around him. My body shivers and slumps slightly as I achieve orgasm. Pietro senses it, slowing down to almost a complete stop and pulling out of me. He jerked it for a few seconds before I saw him reach over for a spare sock of his in my room. He leaned forward again so his chest was pressed to my back and kissed my shoulderblade

"We should train together more often." He smiles.
