Author's Note: I think this one's my least favorite of the bunch. In my head a lot more than a kiss happened after The Boy is Mine but this is how it starts.

Santana is pissed.

She knows it's stupid. After all, she broke up with him only a couple months ago (and not for the reason she'd fed him, either). That doesn't mean he still doesn't text her late at night or that they don't still screw around. Of course they do. They're Puck and Santana for God's sake. They could hate each other and they'd probably still do that.

Except Santana's positive he could shave off all his hair and tell her he was going to become a priest and she still wouldn't hate him. He was her best friend. And she felt like she had some kind of claim on him, even when she probably didn't. It probably had something to do with all of the firsts they'd shared –first kiss, first boyfriend, first time. She would never let herself admit that she thought he might even be her first love, because she was Santana fucking Lopez, head bitch. She didn't do love. And she sure as hell didn't love that bald idiot.

Still, she doesn't find herself pissed at Puck. She was mad at Quinn for a while after the truth got out. After all, it wasn't just Finn who got screwed over when Puck screwed Quinn. If the timing's right (and Santana's actually pretty damn good at math), then Puck was with her when Finn was with Quinn. So she got cheated on, too. It just wasn't as big a deal because her relationship with Puck had always been kind of open. But girl code is stricter than guy code. Guys sleep with their boys' girls sometimes because they're drunk or horny or both. Girls are practically forbidden to look at one of their friend's ex's, let alone their boyfriends.

It was easier to get mad at her for God knows what reason. Logically, she knows a lot of it is Puck's fault. But it's Puck. He pulls shit like that all the time, sleeps with girls who are taken and doesn't think twice about it. But Quinn? Santana's known Quinn almost as long as she's known Puck, and she knows better.

Puck's easier to forgive, if only because that's how he is. It doesn't make sense, but it makes sense to Santana. She's just blinded by possessiveness and maybe a little bit of jealousy. Puck is hers. Her best friend, her first boyfriend, hers. And the selfish part of her doesn't want to share that with anyone. It's why she's never given in to his really obvious hints at threesomes. Not even with Brittany. They're both too important to her for that.

But, for whatever reason, Britt's dream to make out with everyone in the school doesn't bother her as much as Puck's track record does. It's not like she'd ever been exclusively with either of them…well, okay. She and Puck were each other's one-and-only when they were, like, fourteen. Freshman year screwed everything up. Being a football stud and a Cheerio gained both of them a lot of attention. And high school was a time of experimentation…or so Puck had explained to her. Admittedly, it was partially Santana's fault for agreeing to it. She'd kind of…made him the way he was. And she let him come around for casual sex, which was amazing and tortuous at the same time.

It was always good, but the feeling after? Well, it was just sex. There was hardly any connection. Actually, they'd been growing apart –even as friends- and that sucked. They hardly went to each other's houses except as some sort of booty call, which was a far cry from how they'd used to be. They used to go over each other's houses when shit went down. He was at her place the night his dad left and she went to him when her grandpa died. They hadn't just talked in forever. And no, that time when his mohawk got shaved off doesn't count.

The fact that he was going after Mercedes was the last straw. Puck was such a dumbass. If all he'd wanted was to date a Cheerio to reclaim his status as a football and Glee stud, he could've gone after Brittany (which wouldn't have ended well). Or, you know, her. They'd been best friends for God knows how long and he hadn't even thought of her. It was so freaking stupid. Puck didn't even like tubbers. Even if it was just to protect his rep, it stung like hell.

So, just to stake her claim –and make a point to her mohawk-less best friend- Santana had just dueted it out with Mercedes in front of the entire Glee club. She's pretty sure the diva would've beaten the crap out of her if Schuester hadn't stepped in. But once their director was between them, Santana's lips were looser. "Did you get that, Coco Puff? Or do I need to spell it out for you?"

Throughout the entire thing, Puck had sat hunched in his chair, grinning wryly and looking from one girl to the other. Two chicks duking it out for him? It was pretty much a fantasy come true. And they were both Cheerios. The Puckster was back in action. He catches Santana's eye after she speaks and raises his brows skeptically. "Noah Puckerman is mine." And, just for good measure, she throws a couple glares at preggers and man-hands, too. The boy was on his way to being with every girl in this club.

The wheelchair kid better watch out.

"You broke up with him!" Someone –it sounded suspiciously like Kurt- snaps. Santana doesn't care. She's already stalking off towards the door.

"Hey!" Mr. Schue is saying. "I get that you guys are in a really…tough part of life and you sometimes need to express yourselves through song. But if we're gonna take Regionals, we really need to practice." Someone was blocking the damn door. Santana's too busy focusing on her white sneakers to keep from racing back towards Mercedes –because she couldn't try and hit Puck, as much as he might deserve it- so she doesn't notice until she almost slams right into him.

"Move," she all but growls. He's smirking at her in that way he does. Normally, it kind of turns her on. But right now? It was just pissing her off more.

Puck had his arms crossed loosely over his chest and had his head tipped to the side in question. "You know," he says casually, ducking his head a little bit so that his lips are close to her ear. He's being all coy and annoying so the rest of them won't hear. "That was really hot. I haven't heard you hit notes like that since the last time we did it."

Santana rolls her eyes so hard it hurts and crosses her arms right back at him. "Yeah? Well you sure as hell won't be hearing that anytime soon."

"Won't hear what?" Puck parrots, playing dumb. "Won't hear you go up an octave and accidentally say Noah instead of Puck?" He copies her eye roll. Normally, Santana's really good about not calling him by his full name. She's one of the only people who knows why he doesn't like using the same first name as his father. But, sometimes, it slipped. "We both know if I called you'd be at my place tonight."

She grits her teeth and bites back a retort, fixing him with a level stare. They both know he's right. Puck shrugs and reaches out to uncross her arms. He wraps his fingers loosely around her wrists and tugs her back into the room. "C'mon. Let's practice." Santana wants nothing more than to leave him hanging, but there'll be time for that later. When he does call her later (which they both know he will), she'll go over and get him all ready. And then she'll leave him high and dry, making him hide out in the bathroom with a Playboy and his left hand. He deserves it.

Plus, she couldn't leave. That'd show weakness. And she couldn't have the Glee kids thinking she was going soft. So she lets him lead her back to the chairs and they sink down side by side. Mercedes keeps looking back at them and Santana is getting irritated. "She keeps looking over here. What's her problem?"

"Well, I was kinda dating her. I think."

Santana scoffs. "Right. Well, if you haven't done it yet, it doesn't count." She pauses to examine her fingernails. "Not that that's stopped you before."

Puck leans towards her. "Are you still going on about that? Because a little blonde birdie told me I wasn't the only one…" She shoots him a look that quite clearly says that's not the same and you know it. Puck doesn't argue, because that's kind of true. He knows he pulled a douche move on both of his best friends that night. "Whatever. It's not like you didn't know better."

"You should've known better," Santana snaps back. She reaches out like she's gonna shove his face away, since it's really close to hers, but they must not have been whispering as softly as they thought they'd been since Mr. Schuester stops talking altogether and fixes his gaze on the pair.

"Puck?" He pauses and sighs a little, like he knows not to push Santana. He does anyway. "Santana. Do you have something to share with the rest of us?"

Puck shrugs noncommittally, though he looks surprised that Schue had the stones to say anything. Most of the time, there's like ten different conversations going on in the choir room during practice (and one of them is often Brittany talking to herself). Santana, however, seems to take the fact that all heads turned towards them to her advantage. She gives Mercedes a particularly long stare before moving her hand to the back of Puck's head and kissing him firmly.

It's more of a statement than a kiss, though. Her lips are rough and fast against his, and he's turning his head to get a better angle. His eyes are closed but hers are open and she's pointedly looking at Mercedes, like the boy is mine. And, for a while, he is.

But he's Puck and she's Santana, so it doesn't last long at all. He's got his baby momma to deal with and she has other boys to test drive. That's just what they do.
