Sharing (Jean x reader x Marco *modern AU, lemon*)

                                    

                                          
Since I haven't received any requests (which is fine) I decided to do something...adventurous. Oh, and if you didn't notice, I started adding some pictures to the chapters. Slowly but surely. Not like that really affects you, but I thought I'd point it out.
                          
Just a word of caution, this is super smutty. Yeah, I know, my mind is dirty *blushes* but I can't help it that Jean's hot, can I?
                          
I was having a dilemma.
                          
You see, I had a huge crush on Jean Kirstein, who was literally hottest student here. He was always flirting with me, and a few times he even told me I was prettier than Mikasa, which was high praise coming from him. I was positive he liked me back.
                          
The issue?
                          
I also liked his best friend, Marco.
                          
Marco was super cute and sweet, and he often hung out with Jean and I. Whenever we went to get food or hang out at some place, Marco tagged along.
                          
I wasn't technically in a relationship with Jean, so I didn't feel like I was betraying him by liking his best friend. I was afraid that I'd come between them, though, so I tried to hide it. They were so close, and I would never forgive myself if I was the reason they got into a fight. So instead of saying anything, I suffered in silence. It was so hard, since I spent most of my time with them.
                          
Before school, during school, after school, all the time.
                          
And I liked both of them equally! Who was I supposed to pick?
                          
"Hey, (Y/n), you're zoning out," Jean said, waving his hand in front of my face. "What's wrong with you? You've been acting funny all day."
                          
"Did you eat something weird?" Marco asked, looking concerned. "You're usually more talkative."
                          
I forced myself to smile. "I'm fine."
                          
"No you aren't," Jean said, his eyes narrowing. "Something is definitely up with you. You've been like this ever since this morning, and I want to know why."
                          
I bit my lip and lowered my head. It was true, I had been acting weird. I was getting so worked up about this, and it was starting to get to me. Maybe...maybe I should just tell them what's wrong? They'd understand, right? I mean, we had been friends for years. Marco would probably just tell me to be with Jean, since it was obvious we liked each other. But...I didn't want to lose Marco either. Ugh, why couldn't one of my guy friends just be ugly?
                          
"Seriously (Y/n), something isn't right," Marco said, his tone growing firmer. "Just tell us, we won't judge you. We're just worried about you."
                          
"Let's say...hypothetically...I had a crush on two different guys, and I couldn't pick one, and I felt like I was betraying both of them whenever I hung out with either of them?"
                          
"One of them is Jean, isn't it?" Marco said.
                          
Wow, way to be subtle.
                          
I blushed. "I said hypothetically!"
                          
"I don't mind," Jean said with a shrug. "It's not like we didn't notice."
                          
I blushed, my ears growing hot with embarrassment. "I never even said it was you two!" Did I really make it that obvious that I liked them?
                          
"I doesn't bother me," Marco said with a shrug. "I don't have an issue with sharing, do you, Jean?"
                          
"Nope, not me."
                          
I groaned, burying my face in my arms. "You two are horrible," I mumbled.
                          
Jean snickered, and poked my side, making me squeal and then scowl at him. "Come on, (Y/n), that's no way to talk to your boyfriends."
