You groan as you wake up from your slumber. Although, it wasn't really a 'slumber,' since you hardly slept at all. You were in your second year of university, it wasn't that tough. It's just super time-consuming. You were still living with your mom and her new husband (ugh). He was quite the pain in the ass. And please, let's not get started on his brother, James, who is living with us for 4 months. Okay, fine, yes, Barnes is hot, like super hot, but he gets on your nerves and that pisses you off. 

"Morning Mum." you yawn and go to the kitchen to make yourself some coffee. "Good morning sweetheart...Uh, Y/n?" "Yes, mother?" you look at her. Oh god, what is it now? "Your father and I are going for a trip, to the Bahamas, for four days." she chuckles. "Cool, when?" "Uh, the flight is in 8 hours. I'm so sorry honey, I just forgot to tell you an-" "Mom. I'm a full-grown adult. It's fine, I can take care of myself. Relax." You reassure her. "Oh sweetie, no. Bucky will be here to help in case anything goes wrong." "What? mom! I'm nineteen!" I whine, "I know darling but he's already here so..." she shrugs. "Ugh. Fine." 

-Time jump (it's now 9 pm and you're in your room)- 

"Okay, safe travels." You hang up. Your mom had seated in the plane and was about to take off. You dial someone else's number, "Hello?" "Hi, darling. I was wondering when you would call." you could hear him smirk. "You free right now? Come over." "Yes ma'am. I'll be there in 10." he hangs up. 

Soon, you hear the doorbell ring. He doesn't even give you a minute before his mouth latches onto yours. You moan against his lips, "Loki," you bite his lip. "I missed you, darling." he picks you up and latches his lips on the soft spot on your neck, "Fuck," you whisper. He lays you down on the couch in the living room, "Loki, what if James catches us?" "You'll just have to be quiet then won't you, love?" You nod. "Good girl,"  he smirks. He crawls on top of you and removes your white crop top. He groans at the sight of your black push-up bra. "Turn" "Yes-" "Yes what, baby?" "y-yes Daddy." you stutter. "good girl." you turn to your back and feel Loki's warm, wet tongue licking the bottom of your spine, slowly going up. You try to hold back your moan as he sucks small hickeys on the back of your neck. He hooks his teeth on the hook of your bra and unhooks it in one swift go. You moan. He slowly slides his way down to your boxer shorts and yanks them off with his teeth. "Loki. I really liked them." you whine, "I'll buy you a new pair sweetheart." You groan as he licks up your slit, "fuck, Loki." He breathes in your scent, "Fuck you smell so good, y/n." he sucks on your clit as one of his fingers enters your wet hole. You moan. "Daddy, right there, ugh, yes." You scream as he enters another finger. "Shh, you don't want him to catch us, do you?" You shake your head. He keeps thrusting while sucking on your swollen clit. You're almost there, right there. He adds another finger and you lose it, completely. Your hole begins to pulsate on his fingers.

 You open your eyes, riding out of the wonderous orgasm Loki just gave you, You gasp at what you see, James, leaning against the doorframe of the living room door. You bite your lip at him, still riding out. Your eyes flutter and Bucky smirks. Once you're out of the orgasm, you process what's actually happening right now. Barnes. Sex. Living Room. Orgasm. You cover your mouth in shock. "what happened, love?" Loki slides up to your face. He chuckles when he sees what you do, "James. Want to join?" Your breath hitches. What? He struts towards you. "I think Y/n deserves punishment for having sex in a shared area while her step-uncle is staying over. What do say hmm?" "Oh, I think she does." Loki smirks. You look up at Barnes with doe eyes and nod, taken aback by his gigantic bulge poking out of his jeans. Bucky chuckles, "Slut." For some reason, even though you never really liked degrading and Loki never degraded you, you got even wetter as he said that. 

Loki crawls towards Bucky and unzips his jeans. He pulls down his boxers as you sit on your buttock and begin to circle your swollen clit. Bucky's cock was thick and long, just how you liked it. Loki grabbed Bucky's ass cheeks and pulled him towards himself. Loki started licking Bucky's length and sucked on the tip of Bucky's head. "Doll, keep your hands where I can see them. Now."  Bucky orders. You groan and put your hands on each side of you. Loki takes in the whole of Bucky's length, something you were sure you could never do.

Seeing your boyfriend suck a dick was much more arousing than you thought it would be. You moan as you dip beneath Loki and begin to suck his dick, unable to fit the whole length in your mouth. Loki pushes into you, it makes you choke and tear up, mascara running down your face. You moan onto Loki's dick, making him moan onto Bucky's. Bucky grabs your boob from underneath and pinches your nipple, making you cry out. "Daddy, please let me come." "No." bucky and Loki both say in unison. 

You hear Bucky pull out of Loki's mouth. Before you can react, Loki abruptly lifts you up and enters you without any hesitation or time for you to think. You scream in pain and pleasure. "Oh, she's loud, huh?" "Oh, yeah," Loki replies. He begins to thrust as Bucky starts walking behind him. "Up. both of you." You both listen to what he says and slowly stand up, finding it hard not to collapse on the floor. "Y/n, baby, come sit on my dick," Bucky says as he lies down. "Y-yes daddy," you say, doe-eyed. "Loki, once she's comfortable, enter the same hole, from behind." "Yes, daddy." He replies. You slowly climb onto your step-uncle's large dick and slowly thrust down. You moan, "fuck." "gosh, y/n, you're so fucking tight," He growls "Can you move, baby?" You nod, biting your lip trying to hold back your orgasm. "Move." You begin to move slowly, closing your eyes, boobs jumping up and down. You feel another dick at the entrance of your full hole. How is that supposed to fit? Loki doesn't give you a chance to say anything before he plunges into you, you clench and blackout, only seeing white spots everywhere. You come all over both their cocks. 

It took you one solid minute before you could finally open your eyes. "Can we move now, sweetheart?" Loki asks. "Yes please," you say, dying for another release, already on edge. They both begin to thrust, all three of you moaning. "Daddy... Fuck." you shudder. Bucky places his thumb on your pussy and presses it down, making your third orgasm much stronger than ever before. As you ride out of your climax, you feel warm liquid oozing out of your pussy. They had come too. 

After cleaning up, bucky runs to you, panicking, "Y/n! We didn't use protection." You laugh, "Something funny? What if I got you pregnant?" "I'm on birth control, silly." "Oh, thank god," Bucky says in relief. "One more round?" Loki asks. You both nod.
