A/n: spicy LukaNoir this time. Because there's so much potential in LukaNoir... the lets say 'main event' happens next part because this got long.

Cat Noir was always Lukas favourite, ever since the here's first showed up a few years back. And when he got to be Viperion and met Cat Noir properly, he only grew to like him more. It wasn't long before he knew he'd fallen hard, growing a major crush on the stray cat. It really didn't help he was constantly walking  around in black skin tight leather, that has definitely awoken something in Luka.

Although he never thought the relationship would be anything more than him admiring from afar, working together as heroes and that's it. But then there seemed to be some kind of rift between Cat and Ladybug, and after offering to talk about it, he and Cat only got closer. They'd talked until they had to leave as their miraculous was running out of time, and later that night Cat Noir showed up at Lukas window wanting to talk some more. That was the thing, Cat knew Luka was Viperion, but Luka didn't know who Cat was.

There was an air of mystery around the blonde, but he was open enough to form a genuine bond and trust. Even though Luka didn't know who was under the mask, he did know a fair bit about the boy. They were around the same age, 17 and 18 respectively, although anyone could tell that from the height, build and voice of the hero shifting over the years as he grew up. The suit has changed too, more green accents to it, bigger platform boots, choker style collar rather than the popped one.

He also knew that Cat has some family issues, although he wasn't going to pry so he didn't know the details. He knew that he played piano, and had a history of playing sports too. So overall Cat was was a pretty interesting and fun guy to be around. Totally Luka's type too. Even without the civilian name of the boy, Luka knew he could trust Cat Noir, and the friendship they'd been growing in recent months has culminated in them meeting up after dark. Usually Cat would show up at the window of Lukas room, sometimes Luka would sneak out and meet up with him somewhere in the city.

He wanted to do just that tonight, Cat had asked last time if he wanted to go see a movie. But Luka had to decline, his mum and sister were going away for the weekend and he had to stay and watch the houseboat. He didn't mind being left out of this trip, it was a girls thing. He understood the need for mother-daughter time. He'd already been out with his mum for a trip this year anyway. And he didn't mind having the whole house to himself either, that just meant he could be as loud as he wanted with his music and get no complaints.

Instead of a movie, Cat just showed up at Luka's window anyway. Still wanting to hang out even if it was just at home. They played some video games, messed with the many instruments, talked for hours. Somehow, the topic of relationships came up and finally Luka got the chance to ask about how things went down with the bug.

"By the way, things any smoother with ladybug?" He asked.

Cat sighed, rolling his eyes.

"No, she's still being stubborn. I'm not asking her to reveal her identity or anything, I just don't want to be left in the dark about what the hell she's doing with all the other miraculous. Her rules about who can get one and who gets to know identities is all over the place" Cat complained.

"Yikes, hopefully she'll get over that paranoia eventually" Luka replied.

"Even when she does I don't think I can fully forgive her for keeping so much from me. Made me fully fall out of love with her too..."

That made Luka perk up a little, if ladybug was off the table then maybe..?

"Ooh who's the new crush?" Luka teased.

"Wouldn't you like to know? You just want to know if you have a chance" Cat replied, in his usual joking manner. Although... he wasn't wrong.

"Whaaaaat? Noooo totally not. That's gay dude" Luka joked back.

"Don't act like you're not fruity sir pride flag on the roof" Cat snickered.

"With the amount of puns you make you're at least bisexual too mister"

Luka was out to everyone, people knew. Cat? He never actually said the words 'I'm bi' (mainly because he was scared his father would somehow find out). But people around him did know, the other heroes mainly.

"That's why I'm so cool and epic, all bi people are cool and epic" Cat snickered.

"That means I'M cool and epic too" Luka pointed out.

"You are, we're both cool and epic bisexuals"

Luka snickered at the childish sense of humour, but if the chance was there he was going to take it. So he continued the teasing flirting until it was actual flirting.

"Seriously though, anyone I should be fighting for the title of Cat Noir's man?" He teased.

"No, just yourself" Cat teased back.

"Are you admitting you have a crush on me?"

"I'm not saying I DON'T have a crush on you"

There was something about being Cat Noir that gave Adrien a confidence boost, maybe it was the security of no one knowing his true identity but he felt like he could say and do things Adrien never could. Like flirt so openly like this. Even then, he was still Adrien, and still had his moments of flustering.

"I-I mean, it's just like... you're really nice and pretty and all so-" he stammered, realising how how quickly the joking flirting turned to actual flirting.

"As if I'd turn down a chance to be with you Cat, have we not been meeting up these past months because we clearly like being around each other?" Luka replied.

"Well yeah, but... basically I'll stop flirting if you don't like it, I know not everyone likes my flirty sense of humour"

"Cat, it's fine. Would I be flirting back if I didn't like it?"

A moment of realisation come over the blonde, they had been flirting. For a while now. It started out as a joke sure, but it just kept getting more and more serious. They'd been dancing around the topic for a while now, it needed to be straight up addressed.

"You... like it?" Cat asked.

"I'm going to be straight... bi, with you here. I like you, a lot. I know I can't know your civilian identity and all but I know I can trust you. Obviously you don't need to reciprocate, just being friends is enough for me. But... if you did..." Luka explained.

"I mean, I HAVE been throwing all those flirty jokes at you for a reason. I just didn't want you to feel like I was trying to rebound from ladybug or anything, like I was using you"

Luka cracked a smile, he was thoughtful for being mindful of that. But Luka could tell they were more than just that. Although admittedly... there was something hot about one upping ladybug by treating Cat better than she did.

"I don't feel that, don't worry. Honestly... I kind of WANT to make a point that I can be better than bug..." Luka muttered.

"Oh I'm sure you are, miles better" Cat replied.

"You want me to show you?"

Cat was silent a moment, cheeks burning and eyes locked onto Lukas. He'd been craving this, and he hadn't realised how badly he had until right now.

"... please" he muttered.

Flood gates open, Luka grabbed him by the bell and pulled him in. Their lips met, rather than the usual shy and gentle kiss first kisses between couples usually are, this one was instantly rough and desperate. Clearly they'd both been yearning for a while, just hadn't said anything about it yet. Despite his usual domineer on the battlefield that demanded everyones attention, right now Cat was willingly slipping into Luka's venom. Allowing for gentle hands to slip around his waist and pull him closer. The leathery fabric of the hero suit was something Luka always liked the texture of, and running his hands over it, feeling the warmth of Cat's body underneath it, it felt intimate.

The kiss broke only for a moment to take a breath, before diving back into it. Cat wrapped his arms around Luka's shoulders to pull him closer, shifting into his lap. Already he could feel himself getting hot, and the need for this damn suit off was lurking in the back of his mind. Feeling Lukas snake bite lip rings against his own lips added to the excitement somehow, like it was a marker telling him that yes, he was kissing Luka and no one else.

Luka trailed the kisses from his lips, to his cheek, to his jawline and landed on his neck. Just above the collar, he nuzzled into the crock of his neck and planted kisses along the skin, the occasional nip sending shivers down the blondes spine. It felt good, Lukas hands on his waist and lips on his neck, so good... almost... hypnotic.

"That's cute" Luka chuckled.

It was those words that snapped Cat out of his daze and he realised: he'd been purring. Immediately his face went red and he slapped his hands over his mouth to stop it. Luka just gave him a smile and snicker.

"Don't worry, it's cute. I like it. Tells me you're enjoying yourself" Luka assured.

"Ugh I totally forgot I do that when I'm transformed..." Cat groaned in embarrassment.

"No seriously! It's cute. Keep purring please, or... should I give you a reason to keep purring?"

Their eyes met again, full of need and desperation for each other. They were on the same wavelength, they knew where this was going. But they liked it.

"Please..." Cat whispered.

"All the way?" Luka asked.

"All the way"

"Don't worry kitty, I won't hurt you. Just keep purring for me ok?"

Adrien took a breath, feeling Lukas hands slip up his thighs feeling the tight leathery fabric stretching around his skin. That fabric was getting very tight in certain places that's for sure. But that zip down the front of his suit should fix it up quite easily...
