There’s nothing like being invited to a function by someone you’re not too close to. You get to witness the friendship dynamics between your friends and the people closest to them and weasel your way into new friendship connections. Their friends become your friends, and your life becomes an endless circle of beautiful social interactions. The marauders are no strangers to being invited to parties by their friends, but it’s definitely a first for them to be invited to anything by a group of slytherins, let alone Regulus Black’s own friend group.

Sirius and James have their guard up a little too high, because while they cradle their beers and huddle like a pair of penguins, Remus and Lily seem to be having fantastic conversation with a couple of Regulus’s closest friends across the garden. Sirius looks around the vast backyard — just minutes ago you had been singing with your friends to muggle music Sirius had to admit was in fact amazing, and Regulus had been mixing drinks by the makeshift bars and offering them to some friends who chugged them then instantly gagged at the strong taste.

Now, Sirius spots Regulus cradling a tall glass in his hands. The liquid inside it is colourful, and a small plastic straw is sticking out of the glass as Regulus makes his way towards you, trying not to spill the cocktail he made you. Sirius’s gaze is glued to you and his brother, even as James suggests for them to join in on a conversation somewhere. Sirius nods, but it still attentive to the way Regulus holds the glass up higher for you, and you lean down to latch your lips around the straw, taking eager sips from the drink as you carefully shield your face from your hair. Regulus carefully watches you, moving the glass to one hand so he can settle his second arm around your waist as you straighten up, immediately wrapping your arms over Regulus’s shoulders. You instantly press a kiss to your boyfriend's cheek, lips moving softly as you thank him for the drink. Despite Regulus creating abominable drinks for his friends mere minutes ago, this one is absolutely perfect for you — not to sweet nor too strong, but something you'll ask him to make you again.

Regulus grins widely and freely, and Sirius immediately assumes that Regulus is extremely intoxicated to be so overtly happy. But Regulus can’t be drunk, not when his movements are so graceful and co-ordinated. Sirius’s eyes widen when you slot your lips against your boyfriend’s and Regulus immediately reciprocates the act, tilting his head to the side slightly so you can deepen the kiss when you press your body against his, nudging your tongue into his mouth. Sirius averts his gaze when he realises he’s been stood there watching his brother snog the girlfriend he hasn't even met yet.

It’s a good call, because Regulus blindly reaches behind him to put down the drink so he can put both hands on your body, gripping your waist softly as he tangles his tongue with yours. Barty passes behind Regulus, smacking a strong hand onto his shoulder, causing your boyfriend to stumble forward and subsequently causing a moan to tumble from your lips. Regulus’s lips break from yours with a sigh falling from between them. You both turn to find Barty and playfully glare at him, still clinging onto each other, and Barty laughs into the rim of his beer bottle as he catches his best friend’s eye.

Regulus presses a kiss to the corner of your lips to retrieve your attention once more, and he brings up a hand to wipe away at your smudged lip gloss. You stand quietly, letting him brush the excess makeup away with his thumb, holding his hand in place when he begins moving it away so you can press a sweet kiss to his thumb. When Regulus lifts his eyes back up to meet yours, he smiles softly at you, hugging you close with one arm as he spins you both so he can fetch your drink from the counter. He takes a small sip from it then offers it to you, smirking to himself when you open your mouth to chase after the straw. Regulus takes that time to glance around the room, scoffing in amusement when he finds his older brother standing with his arms crossed as his friends make conversation with people.

“Wanna come say hi to my brother?” Regulus asks, immediately noting the slight nervousness that appears in your eyes at the mention. He smiles when you nod nonetheless, index finger coming up to brush against the line of your lips to hide evidence of the passionate kiss you had shared with Regulus. Your boyfriend lifts his hand to cradle your face, his other one abandoning the drink again so he can clean the skin surrounding your lips — seriously this time. He digs a hand in his pocket to retrieve a familiar tube of lip gloss, and you smile widely when he unscrews it, lifting it up to your lips. You part your lips slightly, eyes glued to your boyfriend as he carefully drags the item across your plump bottom lip, pressing his own lips together for you to mimic the movement before lifting the wand again to apply product onto the delicate line of your top lip. You so desperately want to kiss Regulus for the intimate act he has just displayed, but you don't want to ruin his precious work, so instead you mutter “Thank you” and take the hand Regulus offers you when he lets go of your waist.

Regulus calls out his brother’s name, and Sirius instantly feels relieved to partake in conversation with someone familiar to him. Yes, they may still be patching up their relationship, but Sirius definitely prefers Regulus’s company over anyone else’s.

“Y’alright mate?” Asks Sirius as he approaches you both, bringing a hand up to dap up his brother. Regulus lets go of your hand so he can pat his brother’s shoulder as they go into a weird half-hug that only men ever seem to do. “Sirius, this is-” You cut your boyfriend off to introduce yourself to Sirius, holding a hand out respectfully. “A shaker, huh?” Sirius asks as he shakes your hand, and you glance down to where your hands meet, frowning softly. “No actually, I don’t know why I did that.” Sirius smirks, glancing back towards Regulus, who tilts his head to the side with a smile.

“She wants you to like her, is all.”

“Is that so wrong?” You ask quietly, pressing yourself into your boyfriend’s side. Regulus presses a kiss to your temple, shaking his head softly. “Hey, why don’t you go meet some of Sirius’s friends while I show him around? See if anyone’s giving them trouble?” You nod quickly, letting Sirius get dragged away by Regulus. You let your shoulders slump in relief. Now Sirius is going to think you’re shy because you were barely able to utter a single word in front of him. Maybe you just need another drink.

When you snap yourself out of it, you realise you’re being watched by a certain trio. They make their way over to you, Lily leading the pack, and you shortly consider turning around and pretending you didn’t see them. “Scary, huh?” Lily suggests, and you eagerly nod your head. “Most terrifying interaction of my life, I think, and I’ve been given a detention by Professor McGonagall before.”

James laughs loudly at your comment but nods nonetheless, as he mutters “I know that’s right.”

Remus shrugs, lighting a cigarette as he mumbles, “I don’t know, I would’ve thought meeting the parents would be scarier.”

You huff out a laugh, shaking your head in disagreement. “You’d be surprised by how little their parents care. The second they found out who my parents were, I was in the clear. A sad thought, really, but at least they leave us alone." You freeze, eyes widening at your own words, adding "Sorry, I tend to overshare a little when I drink and Pandora isn’t by my side to censor me.”

“At least you have someone to hold you back - all these three do is encourage each other.” Your eyes turn sympathetic at Lily’s words, but you laugh a little at the offended look in her boyfriend’s eyes. You lean in closer to Lily, mumbling quietly “Look, honey, if you need more girls around, we’re here.”

“Come on, Black, don’t try to steal my girlfriend, that’s not classy.” Argues James, but you just raise an eyebrow at him, echoing “Black?”

He freezes for a moment, unsure how to recover from calling you by your boyfriend’s last name, but a hand appears on your waist accompanied by a voice that says “No, that’s right.”

Your face goes hot at Regulus’s words, and you twist your torso to get a good look at him. He shrugs as he meets your eyes, asking genuinely “You do know I’m going to ask you to marry me soon enough, don’t you?” Rendered speechless, you’re unable to do anything but stare at Regulus as his brother and his friends stare at your reaction. “I mean, well, I did, but I…” You trail off, blinking slowly, and Regulus grins, excusing you both from the conversation with the few outliers.

Regulus waits patiently as you open and close your mouth, gathering your thoughts into words before finally saying “I guess I hoped more than I really knew - I just didn’t know we were advertising it to people.” Regulus scoffs lovingly, squeezing your hips “Gonna marry you and build you a nice house our parents won’t know of. And I’ll keep loving you until even after I die.”

You lift yourself onto your tippy toes to press a kiss to Regulus’s lips, mumbling against them “Drinking makes you sappy, you know?”

He hums, replying “I’ve said too much, haven’t I?”

“Nonsense.”

Sirius stares from across the room as Regulus brings you into another kiss and sighs; he thought they had been invited to a party, not an engagement celebration.

Remus (whispering back): Thanks shorty. Why are we whispering?

Regulus (still whispering): I want Sirius to think we're conspiring against him. Please look at him when you reply.

Remus (looking at Sirius): Messing with my boyfriend? Fun .

Regulus (also looking at Sirius): I'm glad you agree.

Sirius, sweating in fear: What are they talking about?
