🔞
…………………..…………………..…………………..……………….
Fooling around with 2 of the hottest heroes on the chats had to be crossing something off your invisible bucket list.
I mean, come on?!
Right now? You had Mark lying between your thighs, eyes sleepy as you combed fingers through his inky hair, and Rex was at your side. His arm across your shoulders, rubbing circles into the skin as you all watched a movie.
It was supposed to be a quiet night in with your favorite boys, but Rex never enjoyed quiet nights…
Small at first, light kisses on your neck, hand rubbing up and down you arm, whispering soft and dirty things in your ear.
Mark perked up, blinking as he watched with lidded eyes, “so pretty…”
Rex smirked, leaning down and slotting his lips on Marks and effectively waking him up fully. The two boys groaned, fighting for dominance as you rose to kneel beside them. Rexs pulls away from Mark, slotting his lips on yours while Mark kisses your neck and collar bone.
“Good boys…” you mumbled, shuttering when Mark used a bit too much force to bite down on your pulse. He whispered a pathetic “sorry” then continued like nothing was wrong. Rex chuckled, his hand in Marks hair as he pet him, “yeah…Mark her up, super boy…”
You huffed lightly, pulling away and moving to undo Marks pants. He stuttered with his breath, cheeks flushed as you began to shimmy his pj bottoms down and around his thighs, “babe you don't have to-AH~!”
He was cut off when your warm mouth took him fully, his eyes tearing with pleasure, “fuck baby…”
Rex smirked, moving in front of Mark who eagerly opened his mouth and flattened his tounge for his pretty boyfriend. Rex sighs, head rolling back,“good job…”
Mark hums around Rex's dick at his praise, feeling proud of himself. He keeps sucking softly, moaning to make Rex shutter. When you reach down to play with his balls, he gasps around Rex's length, his eyes fluttering closed. Fuck, that feels good.
Mark spreads his legs wider without thought, letting you lick his tip. He moans softly around Rex's dick, taking it deeper. "Mmmph," He tenses slightly as you lick his length like a lollypop, then suck on the tip.
He moans loudly around Rex's cock, the vibrations making Rex groan as well. The combination of your mouth and nails digging into his thigh sends waves of pleasure through him. He starts to suck Rex more eagerly.
Rex groans, leaning over to lift the bottom of your shirt up, revealing your ass and wet pussy. You moan as he sticks his fingers in you, crying out softly around Marks dick. Mark feels your moan vibrate against his dick, making him suck harder. He watches as Rex's fingers slide in and out of your wet pussy, making you whimper around his length. He starts to move his head faster, taking Rex deeper each time. "Mmmph..."
You full off Mark, face flushed and moans muffled by his fat tits. You lip his nipple, then take a bite.
Mark arches his back as you pull off his dick and start to play with his sensitive peaks. He whines softly, spreading his legs wider as you bite and suck on his chest.
"F-fuck..." Rex mumbled, He watches as you jerk Mark off, his pre-cum leaking out of his tip.
Rexs pulls out of his mouth with a wet pop, dick twitching, and moves to jerk himself off, swearing. “Mark…lay down…”
Mark quickly rolls onto his stomach, his round backside now on full display. He buries his face into your stomach as he traps you under him, spreading his legs slightly. He has no idea how sexy this position makes him. Your minds both go dirty - "Damn," Rex mutters softly, stroking faster.
“Eat her out.”
“Yeah,” you tease, pushing his head down, “eat me out.”
Tentatively, he extends his tongue, licking hesitantly along your slit. He shudders, surprised at the taste, but continues cautiously.
“What…? You like my taste?” you giggle between moans, pushing his hair back and away from his face. Mark blushes violently as he nods, his tongue darting out again to tentatively taste you. "It's... really good..." He admits shyly, looking up at you with curious eyes.
Rex snickers, rubbing his dick between Marks cheeks, “remind me to get a taste later.”
Mark squeaks as he feels Rex's thick dick slide along his crack, his face turning an even darker shade of red. He buries his face deeper into your pussy, licking more confidently as if trying to distract himself from the sudden sensation. "Mmmph..."
You moan, legs locking around his shoulders to cage his head. Mark whines muffled into your flesh as his shoulders are locked in place, his arms trapped beneath him. He's completely at your mercy now, his tongue lapping more eagerly as he realizes this position leaves him no choice but to please you.
Rex pushes in, moaning, “fuck! So tightttttt.”
Rex grasps his hair, tucking him slow, “heh..Mmm, you like that? Me fucking you as you eat our girlfriend out…?”
Mark nods eagerly, his eyes wide with a mix of pleasure and tears. He's completely lost in the sensation of being used so thoroughly, his body responding instinctively to the dual stimulation. "Mmm... yes... it feels so good..." He whimpers softly against your pussy. "Mmph..."
“Good…cause-ah…im gonna…fuck…” Rex whimpers, speeding up a bit. He reached under Mark, jerking him off, “come on pretty boy…get her to cum with us…”
Mark's eyes roll back at the sudden increase in speed and the sensation of being jerked off. He doubles his efforts, his tongue flicking against your clit with renewed vigor as he tries to make you cum along with them. "Ngh... fuck... fuck... ngh... mmph...!"
You're head falls back, moaning softly, “M-Mark…f-fingers-!”
Mark immediately slides two fingers into your wet pussy without hesitation, curling them upward to hit your G-spot. His brain is quickly rebooted by desperation as he tries to make you cum as hard as possible. "Mmmph... fuck... come on..."
I whimpered, clenching on his fingers as I see stars. The feeling of his coaxing an orgasm out along with the rhythmic flicking of his tounge makes you tense up, “FUCK!”
Mark's eyes widen with triumph as he feels you clench around his fingers, your juices coating them. He continues to lick and finger you through your orgasm, his own pleasure building rapidly from Rex's thrusts and the hand jerking him off. "Mmmph... fuck... I'm gonna..."
“Cum.” Rex smirks, squeezing his tip, “fucking do it.”
And he does, hot and stick ribbons as he crus out. Tears finally fall as Rex pounds hard as to chase his own release.
Rex swears, slapping marks ass before cumming with a grunt. His blunt nails digging into Marks ass.
You pant a laugh, watching Mark fall on you and Rex roll to your side.
“We…we should have done this when we all first met…”
Hi! Was just wondering if you could do mark x rex x gn!reader hcs where reader basically are/has the personality of blue diamond (from steven universe) story/scenario can be completely up to you! :3

Ship: Rex x Gn!Reader x Mark
Fandom: Invincible
Warnings: None
This is a small drabble I was able to do after rewriting this a few times.

As the battle against a villain they had never seen before drags out, Rex is wondering where the hell Invincible is. Or, where the hell the rest of the heroes are. It’s hard when it’s only Rex on the scene, trying to keep this villain from injuring more civilians. All he can do is throw small explosions to move the villain back while trying to use the big ones to at least stun him or injure him. It feels like hours before Atom Eve and Invincible show up and have a hand in safely capturing this new villain.
Invincible, Mark Grayson, turns to Rex with a sheepish smile and hovers down to land in front of Rex.
“Sorry about that, Eve and I-”
“Were what??” Rex snaps without even thinking about it.
Mark is taken aback before getting defensive himself, “Don’t tell me you’re jealous. You and Eve aren’t even dating anymore!”
Rex can’t let the real reason slip through, he can’t let Mark know that lately he catches himself staring at Mark a little too longer than usual. How he has been slacking as a hero, because he’s distracted thinking about Mark, and secretly hoping that Invincible will come while simultaneously giving him shit saying he had it- in a joking manner of course. He can’t let him know he doesn’t want Mark dating Eve because he wants Mark. He bites his tongue and walks away, muttering about how all of this is bullshit. Mark just sighs and rants to Eve about it, he thought him and Rex were cool but as the last two weeks have been going on- it appears differently.
Rex is helping check on the civilians among the one building that was destroyed. Good news is the building was small, and caused minimal damage- and it was a work building meaning no one lost a home. Someone immediately catches his attention. They appear sad, maybe they’re hurt or worried. Something, something he should definitely check on to make sure they’re okay.
“Hey, are you hurt? Do you need medical attention?” He asks politely, while scanning over their body for obvious injuries.
“Ah no, I’m fine.” Their voice is tranquil to listen to, calming but also in a state of grieving. He wants to ask more questions, but none are coming to mind as they lift their head ever so slightly so their eyes are available to look at.
🌨️₊˚.🎧 ˚.🩵*🎐✩｡
That was when you met Rex. He was checking in on you every so often, to the point it would be considered weird. But he quickly clarifies that your demeanor seems blue, and he just wants to make sure you’re at least mentally okay. The thought warmed your heart and you were able to make small talk with him. You could tell that it was more than just your sorrowful yet tranquil demeanor that intrigued him however. You definitely knew when he slipped a piece of paper with several digits on it, along with his name. It was just confirmation.
🌨️₊˚.🎧 ˚.🩵*🎐✩｡
It took you a few days before you texted him, because of several reasons. One, you were looking for a new job. Two, you were distracted and somewhat laying in bed all day. Three, he made you a little nervous. Perhaps it was a crush forming, or perhaps the man was just intimidating. However- you finally got the courage and sent the message.
You: Hi, it’s me from the other day.
Rex: Took you long enough
Rex: Jkjk
Rex: How are you doing?
After making small talk with him, he tries to call you. You jump at the notification flashing on your screen and you take several deep breaths before answering.
“Hello?”
“Hi, do you wanna go to dinner with me?”
🌨️₊˚.🎧 ˚.🩵*🎐✩｡
At first, dinner with Rex was peaceful and good. He knew the perfect amount of talking to do, knew when you wanted to be quiet for a minute to enjoy the meal without someone talking with food in their mouth. He seemed like a genuine guy, so far- a second date was looking promising for the both of you.
That was, until halfway through the main course meal a man harshly sat down next to him. He crossed his arms like he was mad at Rex (and you couldn’t help but look at how his arms flexed in his short sleeved T-shirt.). Rex looks shocked for a moment before he grimaces.
(In Mark’s defense, he didn’t know this was a date he was crashing)
“Are you going to tell me what’s your problem? I thought we were going good but you got mad at me? Is it jealousy, Rex?” Mark says in a demanding but angered tone. Rex matches the energy, because ain’t no way Mark just crashed on his date talking about being jealous.
“This can wait-”
“No, because you’ve been ignoring my texts and calls. Why are you so mad? I’m not-”
“Mark, I’m in the middle of something.” He gestures to the table, food, and to you. You sit there awkwardly, and have a completely different impression of what is going on.
“Rex, are you in an open relationship or something? Is this your boyfriend?”
The two whip their heads around to you, stunned by the blunt question. They both talk over each other, trying to clear things up, trying to smooth things out, and trying to explain themselves. You have to calmly interrupt them, by holding up a hand.
“I don’t mind, but I would’ve preferred a heads up. Unless you were planning to tell me later during dinner, then I wouldn’t have minded.”
Rex cuts off that thought, “Mark isn’t my boyfriend.”
Mark is sitting there, connecting dots before he gasps, “Wait, were you jealous of Eve?? Do you like me?”
“WHAT”
🌨️₊˚.🎧 ˚.🩵*🎐✩｡
This is when you enter the stage of trying to navigate Polyamory with them. It took a long talk about it, with you explaining the concept to them before they decided to try it. Mark is interested in you, but not in the same way Rex is. Rex sees you as someone who is a calming force in his life, someone who balances out everything and is very empathetic. Mark sees you as someone who can understand him a little better than most on an emotional level. Even if you don’t go through what he did, the way you take on his emotions makes him feel like you deeply understand. Who knew that you would be the bridge that helped Mark and Rex make up and see their feelings for each other- and for you?
can I request hcs for mark x reader x rex poly relationship?
Yes you may! I love them both so I was excited to write it! I wasn’t quite sure if you wanted it in a way where they both date reader and not each other, or they all date each other so I wrote it in a way where they’re all dating each other! Hope you don’t mind ^^
Mark x Reader X Rex (Poly)
Spoilers for Season 3!
Slightly suggestive topics
All three of you have never been in a polyamorous relationship before so it was a new learning experience for everyone. You were probably the first to get used to it compared to the other two- especially since they were in monogamous relationships beforehand.
ᯓᡣ𐭩 Sleeping Arrangements:
None of you live together (not yet) so whenever you guys have time, it’s just sleeping at each other’s place. Sleeping with the two of them is a nightmare. Mark has night terror and it leads to him screaming in his sleep and kicking or throwing his arms around. Rex has restless leg syndrome and he’s constantly kicking or moving his legs in his sleep. He doesn’t stay still, often pushing whoever is near him either off the bed, or closer to the other. He also snores as loud as fuck, if you have misophonia… it’s torture to listen to him. you’ll wake up looking like you’ve been through hell the two wake up looking like princesses that had a peaceful sleep.
Mark: “man, my body feels surprisingly rested. I think I only had one nightmare last night”
Rex: “Same! My legs aren’t as tense this morning!”
You: “…”
ᯓᡣ𐭩 Protectiveness:
Mark is stronger than you and Rex, but he doesn’t treat you like you’re fragile antiques to be protected…. Most of the time. He does have his moments where if he will have a nightmare, or his teammates may get hurt and he will start acting a little overprotective for that moment. If you’re a hero, you’ll get the same amount of protection as Rex. If you’re a civilian, Mark is going to be more protective over you. This will last for either a few days or a few weeks, depending on the situation. Other than that, neither him or Rex will treat you like you need to be protected like a child.
Rex is not very particularly protective- in the sense of overdoing it. It’s just enough. Whenever Mark gets overprotective though he is quick to call it out and try to shut that shit down. He does not like being coddled.
ᯓᡣ𐭩 Family:
Debbie loves you and Rex, welcoming both of you with open arms. She wants you both to feel like family. Oliver could care less honestly, he likes Rex a little more than you because he will play fight with the Rex…. And win.
If you have a good relationship with your family, both Mark and Rex will try their absolute best to make sure your family likes them. Mark is a natural at it, however Rex will overdo it to the point it sounds like he’s full of himself. Oops
If you don’t have a good relationship with your family, that is absolutely okay. They will reassure you that they’re your family now.
ᯓᡣ𐭩 Movie Nights:
Because of how often it is that date nights get interrupted, it usually ends up being just casual movie nights. It usually starts with Mark and Rex arguing. Not intense or anything, just back and forth. Rex always wants to pick the movie, but Mark will often fight him on it even if he doesn’t care how much on what movie they will pick. If you have a movie in mind, Mark will intensely fight to watch that movie because he doesn’t want Rex to have his way lol. Rex will grumble and give in.
If Mark has a movie he really wants you two watch with him, he WILL be that person to pause the movie and wait for you guys to stop talking because he is slightly agitated.
Mark: “no, I’ll pause and wait for you guys to stop talking.”
Rex: “Oh my god, Mark”
Mark: “There's an important scene coming up and I swear to go Rex if you ask “what just happened?” Or state “I’m confused” I am going to tape your eyelids open”
You: “Love, we’re sorry, we’ll stop now. Now please start the movie again…”
ᯓᡣ𐭩 Love Language:
For Mark, it’s physical affection. He needs one of you to have skin touching him after a long day at work. Safe to say he’s also a fan of PDA. He may rub your arm or press light kisses to your neck, or maybe just rub his face to your neck. With Rex, he will throw himself on his back, sometimes catching the other male off guard.
Rex’s love language is words of affirmation. He gets giddy if he gets a little praise for anything he does, it makes him feel completely like a good boyfriend. In a way, it’s often Acts of Service paired with Words of Affirmation. He does something for either of you and then he wants praise. Does Mark need a shoulder massage? He’ll do it. Do you need help with a task? He’s on it. He likes to act like he is annoyed first before doing anything.
ᯓᡣ𐭩 Relationship Insecurities:
Rex is doing a lot better than when he was with Eve when it comes to jealousy- but sometimes it’s still there. He has FOMO, he wants to know everything that is going on when he’s not around. He’s not jealous of you and Mark being alone, it’s more of the fact that he wants to know everything that is going on in both of your lives. It gets on Mark’s nerves sometimes.
Rex: “Oh? Oliver is sick? You didn’t tell me that”
Mark: “Because he just got sick this morning…”
Mark is afraid of being a disappointment. He’s afraid he’s going to be not good enough and maybe he’ll ruin the relationship. It’s not obvious, he doesn’t make it all that known but sometimes a late night talk will get this information out of him.
You: “You can always express this Mark. We’re both here to listen”
Mark: “Thanks, I love you both.”
ᯓᡣ𐭩 Kisses:
Mark likes to receive kisses on his jawline. It’s a little ticklish there and he may give a slight shiver and gasp if he gets a kiss there. As for giving kisses, he’s a gentleman and likes to kiss your knuckles. Rex doesn’t like being kissed on the knuckles so Mark will kiss his cheek.
Rex loves to give out earlobe kisses. Mark is ticklish and will squirm away and he will absolutely tease him about it. If you’re ticklish as well, best believe he is not going to exclude you from the teasing as well (or as Mark likes to call it: “harassment”) As for receiving kisses, he likes kisses on his nose. It’s so gentle and affectionate to him.
ᯓᡣ𐭩 Habits:
If Mark isn’t going out as Invincible right away he will get up early for a morning jog. He mostly goes by himself but he will invite you and Rex to tag along sometimes. Problem is, he does not look back during the jog and he is leaving you and Rex in the dust I fear 😭 He will be back at his house like, “I didn’t even know when I lost you guys”
Rex has a habit of losing stuff at your guys place. He’ll leave socks, money, notebooks, and once even his ID. He does it a lot yet he immediately will panic and not even think to ask you or Mark if it’s at your place. “Guys I am so fucked I lost my ID. What if I dropped it while-“ You will cut him off and explain you have it on your nightstand and Mark will laugh at him.
ᯓᡣ𐭩 Sick:
If Mark is sick, which is rarely as he has a great immune system, he is wiped out. He is curled up in bed, sleeping most of the day. Though he will try to get you and Rex to cuddle with him. Rex is a lot more hesitant to do so if Mark has the stomach flu but if not he will. Hopefully you know how to take care of him, because Rex, why he is trying, sucks at figuring out how to take care of someone who is sick. He will forget to give Mark medicine, or to check his temperature again.
Rex is kind of a brat when he is sick. He won’t tell either of you what he wants but will get mad if you can’t read his mind. Then he’ll groan about being bored, then whine a little that he’s miserable. He does want both of you around though. He will talk until he’s exhausted and then want the both of you to talk to each other to fill the quiet. Plus he likes listening to your voices.
Lord help you if you are sick. These two will somehow become dumb and dumber when trying to take care of you- it’s like them trying to be helpful is cancelling the other out. Do you want to be left alone while sick? They will not let you, they will invade your personal space. Mark is constantly checking on you and Rex won’t stop talking to the point you won’t even be able to sleep. If you get sick, it’s best to not tell them and wait until it passes over.
ᯓᡣ𐭩 Angst: (spoilers for season 3)
If we are going off canon, the Invincible War was hell. At first, Mark thought it was bad enough that there were variants of him killing and destroying everything- but hearing how Rex sacrificed himself to kill a variant of him broke something inside him. No matter how much you try to comfort him it’s not enough. He will greatly distance himself- to the point it will make you wonder if the two of you are even dating, but he will come back. You’re all he has left now.
ᯓᡣ𐭩 Fluff:
Mark and Rex love doing domestic life stuff with you. Doing dishes together may feel like an obnoxious chore, but they will make it fun. Rex will turn on music and dance while Mark hums along. If any of you are in a bad mood he will start playing Kesha or Katy Perry in hopes of cheering you guys up. Mark is mostly a vibe, he goes along with anything and will laugh the whole time.
ᯓᡣ𐭩 Smut:
Keeping it not extremely explicit but here’s some fun facts about them in bed.
Mark is VERY vocal. To the point where you might have to put a hand over his mouth. Just loud moans and jumbled up words that immediately come to mind. First time all three of you were together he bit his lip to be “modest” and then on the second round- loudest whines ever came pouring out of him like crazy and it shellshocked both you and Rex at first. Whether Mark is on top or bottom (or both) he WILL be loud about it.
Rex loves thighs. Both you and Mark have lovely thighs and he will leave hickeys on them. He will just put his head between your thighs and stare up at you while licking over his hickey he left. With Mark sometimes he will be a little rougher- wondering if hickeys will even be left on Mark’s skin. (Answer to that is not really. They’re barely visible and fade within an hour or two) So that leads to him sometimes harshly biting on Mark. Mark will let him half the time.
ᯓᡣ𐭩 Pet Names/Nicknames:
Rex will call Mark pretty boy or golden boy- depending on his mood. Pretty boy is more flirtatious and golden boy is more in a teasing manner. He tried to use the nickname puppy for Mark but it sounded like a sexual term and Mark quickly shut that down.
Rex will call you babe. Short and simple, and sometimes Mark responds to it too but it’s mostly reserved for you.
Mark uses Hun for you. It’s soft and gentle, just like him, and it carries so much affection.
He will call Rex baby, it started as baby boy but it made Rex too flustered so he shortened it. However he will call both of you “My Love”
