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”
