You're Chris' girlfriend—always been off limits. You'd been off limits since Chris had made it known that he had a huge crush on you, which was like.. a year or so ago. So a long time, inarguably. Matt had never found himself wanting you, since he respects your relationship with Chris heavily. He's always nothing but respectful around you, never trying anything on you.
However right now? You're basically doing the work for him. The friend group had gone out to some club, a little celebration for the triplets reaching 7 million—full of drinks, music, and warm, sweaty bodies. It's a good time, it's fun.
Til' Chris had needed to take a piss, leaving you in Matt's care for the time being. Matt had known you had a few drinks in you, and that you weren't exactly in right state of mind, judging by how you were dancing around and giggling drunkenly.
And he hadn't intended for this at all—he and Chris had coincidentally worn similar outfits, and with how similar they look, it was easy to get the two of them confused for anyone who didn't know them personally. You know them personally, obviously, Chris is your boyfriend. But drunken you? Not a fucking clue. Hence the way you're all over Matt right now, thinking it's his brother. "Oh, shit, hey—" he swallowed thickly, his eyes dropping down to your chest pressed up against his.
He's literally fucked. Matt swallows thickly, glancing up in the direction of where Chris had gone to the bathroom then back at you. He literally can't just.. shove you off him, he needed to make sure you were safe. And the best way to do this was to keep you pressed against him, right? "Hi," he lets out breathily, a nervous laugh escaping him.
He gingerly places his hands down onto your hips, his cheeks flushing with heat a little bit before he glances back down at you again. God, you're gorgeous, and so soft against him. He shouldn't be doing this—really shouldn't, you're his brother's girlfriend.
But here he is. And—he kind of likes it.
