Your heart thumps against your chest as you sit in the back of Eddie Munson’s van, the two back doors open as you sit in the middle of Steve and Eddie. In your mind, though you aren’t particularly religious, you say a prayer that this date goes well and that Eddie’s van doesn’t explode from the tension that’s between the three of you.
It all started when Steve Harrington, your boyfriend of several years, was introduced to Eddie Munson by Dustin Henderson, a mutual friend of both Steve and Eddie. You had been there too, beside Steve, when Dustin introduced Eddie as his friend and leader of the club Dustin was so loyal to - the Hellfire Club. It was obvious from the very beginning that Eddie found you stunning, his cheeks flushing with nerves as you gave him a hug, glad to meet another friend of Dustin’s. It had surprised Steve when he was turned on, only a little, when he noticed Eddie’s obvious attraction to you. Although you’d never admit it out loud, especially to Steve, you found Eddie Munson handsome, sweet and charming. There was something so cute, so endearing and genuine about Eddie. He was shamelessly funny, joking around with you, Dustin, and Steve with ease.
It had taken several days for Steve to bring the interaction with Eddie up to you. “So that Eddie guy,” Steve had said, glancing at you. You were sitting in his room, nestled on his bed watching while he picked up his clothes that were thrown about the room. “He obviously thought you were cute.”
You had laughed, amused. “Oh really? What made you notice, the fact that he blushed when I hugged him or the way his eyes took in my entire body,” you said, glancing at Steve to see if he was mad or amused too. “Are you jealous?”
Steve snorted, shaking his head. “I’m not jealous, I was actually turned on by it.”
You frowned, now staring at Steve. “What?”
Steve paused picking up his clothes, tossing them into the hamper. “Listen, and don’t think I’m weird, but I don’t know, I found it kind of hot that another guy liked you.” Steve’s eyes moved off of you to the floor and then back to you. “You think I’m weird don’t you?”
You shook your head, realizing that your mouth was slightly agape. “No, I-, I’m just confused, Steve. What are you saying?”
Steve shrugged, “I don’t know, I saw this program on tv about people that have a third partner in their relationship, you know polygamy, throuples. I thought it might be interesting to add a third person, maybe somebody as unique as Eddie to our relationship.”
Your jaw dropped then, totally blown away by your long-term boyfriend’s admission. Steve had never suggested such an idea before, something so out there as being in a trouple relationship. As caught off guard as you were, you acknowledged that Steve had never done you wrong in your relationship, not once in the several years you had been dating. He’s always been loyal, kind and caring; he wouldn’t suggest something that would ruin that perfect track record. You decided to go with it, loosening the tight reigns that you had held throughout your entire relationship with Steve.
It was frightening, to say the very least, when you and Steve approached Eddie with such an offer. Eddie was equally caught off guard, yet intrigued. Eddie knew nothing about him was normal; he’d been labeled a freak for as long as he could remember, he was a nerd, a drug dealer, and comes from an interesting family background. Why couldn’t he add polygamist to that long list? You and Steve seemed to being decent people, obviously in a stable relationship, must be a little freaky to come up with an idea to add Eddie to your relationship. In the end, Eddie agreed to try the arrangement out, joining you and Steve on a date night.
You’re at the Hawkin’s drive in theater viewing ‘Aliens,’ what is allegedly supposed to be the hit movie of the year. Eddie had offered to bring his van for the three of you to sit in, the back of it leaving a lot of space to hang out and stretch your legs while you watched the movie. The drive in theater is packed, much of Hawkin’s High utilizing the opportunity to screen the movie on the extended weekend.
Beside you, Eddie and Steve converse fluidly around you, bending in front of you and behind you to pass comments and continue conversation. You sit between the boys, zoning out at the reality of the entire situation, of what you’re doing sandwiched between the two handsome boys. Although this idea of being a throuple with Eddie and Steve is new, a part of you wants it to work. Having one sweet guy in your life was amazing, but having two? Could you really be that lucky? Occasionally, Steve nudges your arm with his hand, attempting to include you in the conversation.
“Did you hear that, babe?” Steve says, bringing you out of your thoughts. “Eddie plays at The Hideout in a band; he invited us to go watch him sometime.”
You hum, offering a smile. “That would be awesome, we’d love to.”
You were pleased that the two boys were getting along so well with each other, conversation flowing between them with ease, which just made the possibility of Eddie officially joining your relationship more real. It was all settling in to your mind though, each passing minute allowing you to adjust to the reality that it will no longer be just you and Steve but you, Steve and Eddie. That could be good though; the more the merrier is how the saying goes, right?
The movie begins a few minutes later, although you couldn’t tell by the way Steve and Eddie continue to converse. Thankfully, when you three had arrived at the drive in, the theater attendants told Eddie to park the van in the back row since his car was tall and would block other’s view of the screen if it was anywhere but the back row. This fact also ensured that Steve and Eddie’s antics wouldn’t interrupt other’s movie experience.
You tried to keep your attention on the movie at first, however, it became hard to do that when Steve made a game of tossing popcorn into Eddie’s mouth. You couldn’t help it anymore; you joined in on the fun, tossing the small, round candies that you had bought from the concession stand into Eddie’s mouth too. The game flips eventually, Steve now on the receiving end various foods being thrown at him. Through the course of the two hour movie, you, Steve and Eddie had done a cart wheel contest on the open space next to the van, which is where you learned Steve can’t do a single cartwheel and Eddie is talented at entry level gymnastics moves.
Steve had always made you laugh, his sense of humor always hitting your funny bone, yet Steve and Eddie together was overwhelming and you couldn’t remember the last time you had laughed so hard. To be honest, Steve and Eddie are near perfect for each other, able to find things to talk about with ease. They were two completely different kinds of guys: Steve came from an upper class background, a more clean-cut, typical guy while Eddie was eccentric and unique, a weedhead, an artist and nerd of the game ‘Dungeons and Dragons.’ Nonetheless, the way they acted on this date was as if they’ve known each other forever.
After all the games, you sit, tired, on the edge of the backside of the van. Steve moves from the open space next to the van to sit beside you, wrapping his arm around the front of you and leaning back against the side of the van. Your back leans against Steve’s chest, his arm securing your position. You notice Eddie lingering to the side, eyeing you and Steve’s position. You feel bad for a moment, knowing that he feels out of place.
You pat your lap. “Come sit with us, Eddie. There’s lots of space for you too,” you say with a soft smile. Behind you, Steve smiles, then glances back at the movie screen. He attempts to understand the movie, the scenes that play out not making any sense as he missed the first half of the movie due to horse playing with you and Eddie. Steve gives up after only a few seconds.
Eddie moves to where you and Steve sit, climbing into the back of his car to join you both. You help Eddie arrange himself among you and Steve, suggesting that Eddie lays between your legs, his head resting on his your lap. Eddie does so, taking the second to ask Steve for approval.
“Is this okay, Steve? To lay on your girl, I mean.” Eddie asks cautiously
Steve smiles, gesturing towards you who still lays against his chest. “Go for it, man. She’s your girl now too.” A smile tugs at the corner of your lips, not very surprised at the calm, euphoric feeling from the way being both Steve and Eddie girlfriend and from the way Steve easily accepts Eddie without jealousy or hesitation.
Eddie softens, laying his head onto your lap gently. His arms wrap around your legs, your body now his personal pillow. Your hands go into Eddie’s hair automatically, mostly out of habit as it’s what Steve likes when he lays like Eddie does.
Down below, Eddie purrs with content. “I can get used to this easily.”
