Okay so this is a request from a friend and she wanted me to use her name in it so it is not a Sam x reader smut, it's a Daniell x Sam smut, sorry if you are disappointed.

Danielle's POV
I just had to fucking agree to this game of Deans, granted I did think I could win, I mean it was as simple as a race and I thought that all the burgers and fries he ate would slow him down a bit but no he had to beat me. "Okay, Daniell we had a deal, so take off your clothes and get on the table." Dean walks out of the room, I know Dean has a major crush on me and he thinks doing this is going to get him in my pants, I pull off my flannel and my shorts. The black lace bra and thong I am wearing will surely impress Dean, too bad he is not the Winchester I want to impress. Dean walks back with a beer and takes a seat, "Dean do I have to do this?" He looks at me and nods his head yes while staring over my body and hungrily licking his lips. I turn on some music and climb onto the table and start to lazily sway my hips to the beat, "oh come on I know you can do better than that." So I start to get into the music and seductively dancing on the table and I can see the tent in Dean's pants.
Just as I was about to do that dance move where you kinda go down into a crouch position and come back up slowly, the bunker door swings open and I see a red-faced Sam. "Danielle get your ass down from there now, what the hell do you think you are doing!?" Sam pulls me away from the table and down the hall, I can hear a faint shout of "bitch," from Dean.
Sam throws me into his room, and I am bracing for his lecture. "Danielle do you know what Dean would have done to you if I didn't come in? He was probably planning to use you like some cheap slut, and by the way, you were dancing he probably thought you were one." He's too calm for what the thing he just saw, but the next words that come out of his mouth surprise even him. "Danielle I don't want anyone touching you except me." He pauses, just for a second, then he grabs me by my throat cutting off my airway and smashing his lips into mine, he bites my lip and when I gasp he forces his tongue into my mouth. Sam pushes me onto the bed and his hands start to roam over my body. He plays with my breasts through the thin fabric of my bra, but it's not enough for him or me we want skin on skin contact, so he reaches around and expertly undoes my bra clasp. Sam pulls away and looks into my eyes, "if you are going to act like a slut, I'm going to treat you like one." From just those words I moan, and I moan even louder when his lips attach to my sensitive nipple. His tongue swirls around it while he sucks, then he gives the same treatment to the other one. Then he is kissing down my chest to the edge of the black lacy thong, "Danielle when did you buy these, and why did I never know about them?" His fingers hook into the edge of them and he slowly pulls them down, peppering kisses on my milky white thighs. Then his tongue is licking its way inside of me and I am moaning from the contact.
Then his tongue is gone and he is pulling off his clothes, "Danielle get over here and suck my dick like a good slut." I crawl off the bed and over to him, I slide my hands up his legs and lick a long stripe from the base of his cock to the tip. He grabs my hair tightly, this causes me to moan and he forces his dick into my mouth and fucks my mouth roughly. I love how he is using me, it's like every fantasy I have had when he came out of his room without a shirt on, and like all the wet dreams I have had about him. After about five minutes of him doing that I am being pulled up by my hair and bent over the bed. "You want me to fuck you? You want me to fuck you like the slut you were being for Dean?" Oh god yes I need to be fucked now, I nod my head and he lines himself up with my entrance, and pushes himself inside of me, slowly, I'm guessing he is being slow because he doesn't want to hurt me. "Sam, please, faster." I pant out and he actually listens, he starts to pound into me. The pleasure that runs through me as he hits my sweet spot over and over has me cumming in minutes and he is cumming minutes after me.
Sam collapses onto the bed next to me and puts his arm around me. "Danielle you are not allowed to do that ever again, you understand me," he whispers into my ear, I love how possessive his voice is and how it has dominance radiating off of it. I can't help but answer with a "yes sir." Soon we are both falling asleep with his arms wrapped protectively around me
