PIPER

The phrase "athletic dorms" is still ringing in Piper's head as she flashes her ID at the desk attendant and walks up the three flights of stairs to get to Reyna's dorm room, but the meaning of it doesn't exactly hit her until she sees the trophies and the purple and yellow jersey thrown across the bed.

"Oh, fuck, you're a field hockey player," Piper groans. "Ugh, like you couldn't be worse."
Reyna turns to her, her braid hitting pretty hard against her back. "Do you have a problem with sports?"

"Only the goddamned stupid ones where you wear skirts."

One of Reyna's eyebrows raises and she folds her arms across her chest, to which Piper's response definitely isn't staring at her. "So you're against lacrosse too?" Reyna asks carefully.

Piper takes a step toward her. "Is it really practical to wear a freaking skirt while playing a sport?"

Reyna walks toward her and pins her against the door with her eyes and a hand planted on either side of Piper's head. "The kilt," Reyna corrects, "usually has shorts underneath it and it's traditional, you imbecile."

"Ooh, big words," says Piper with an eye roll. "What are you going to do next, recite the periodic table while writing out pi? What a turn on." Piper decides right there and then that that will never be a turn on no matter how much it might, actually, seem a little hot.

"Coming from a chick who can't say a single sentence without swearing, I can't say I'm taking much offense from that."

"God, would you just shut your self-righteous mouth?" groans Piper. "Jesus, you were so much hotter when you weren't talking."

"So were you," replies Reyna with a harsh laugh.

Their eyes lock and for a split second, Piper's considering hitting Reyna, but then somebody moved and somebody grabbed the other and somebody moved them on top of the bed, where Piper slams her shin into an unpacked suitcase but couldn't care less about it.

For a few seconds the two of them silently fight for who ends up on top, but when Piper gets her hips straddling Reyna's they both know the fight's over.

"See?" says Piper, grinding her hips onto Reyna's. "If neither of us talk, then isn't everything better?"

"Then why did you start talking again?" If Piper had to quantify it, that sounded almost like a growl, and it made heat pool between her legs like never before. Piper pressed her hands to either side of Reyna's head and kisses her, slow and deep, until Reyna's nails are scrabbling against Piper's back and she's basically whining against Piper's lips.

"Because when I talk," Piper mutters against the skin of Reyna's neck, "I don't piss anyone off," she lightly nips at Reyna's earlobe, "like somebody else."

Reyna can only gasp in response, and Piper grins as she feels Reyna writhe against her, her body begging for the friction.

Piper's hands go for Reyna's jeans, and then, suddenly, Reyna freezes up.

Piper moves off of her immediately, putting her hands up like she's under arrest (what the fuck was she DOING?) "Are you okay?" she asks. "Is – did I –"

Reyna sits up and Piper takes her in briefly, her hair flying out of the braid, eyes dark, shirt halfway up her chest (did Piper do that? She didn't remember doing it. Damn, did REYNA do that?)

"No, it's fine, get back here, I just haven't done this before." Had it been any other answer, Piper would have dived back onto the person.

But she's never been on this end of the deal before.

"Really?" Piper asks. "Really?"

"Yes. Yes," replies Reyna, rolling her eyes dramatically. "Can you just get naked so I don't have to think about you talking again?"

Piper still feels half hesitant, but Reyna's frustrated groan as she pulls off her shirt and unhooks her own bra and flings it away blurs out any logic in Piper's mind and all she can think is, "holy shit her tits are PERFECT."

Piper pulls off her leather jacket and the black bustier underneath it, throwing it somewhere she'll find later, and, before she can get to it, Reyna's reached around her to her back and is pulling her bra down her shoulders. She tosses it to the side, and the bra disappears into the darkness. Another thing Piper will have to look for in the morning.

"You have too many tattoos," Reyna comments as she lets Piper kiss along her collarbone. "I mean, seriously, what are you going to cover next, your forehead?"

"Yeah," says Piper, muffled, "I'm going to tattoo, 'Reyna's a priss,' up there."
"Again, so much cuter when you shut up."

Piper moves to glare at Reyna. "You asked."

"You stopped."

Piper gives her a look. "Well hit me with a hammer and call me Spiderman, how did I miss that giant piece of something that I did? Let's go to Captain Obvious for further news!"

Reyna groans and tips her head back, giving Piper a distractingly good look at the expanse of her soft skin. Piper's got a thing for collarbones, and Reyna's is deliciously tempting.

"Is the snark part of the foreplay or are you just incapable of acting like a human being for more than thirty seconds?" Reyna asks. "Because I'd really like to get this done. I have a bunch of classes to prepare for."

"You're such a nerd," Piper groans as she kisses Reyna firmly again, and this time she wills herself not to comment on the fact that Reyna's commenting on god-knows-what. Words are useless when Piper gets to this point. All she wants now is to get naked and laid, and talking is not going to make that happen any time soon.

It takes a few fumbly seconds to get Reyna out of her jeans, and Piper feels more than hears her take a deep breath (Piper barely remembers her first time – she was sixteen and it was with some guy who wasn't Leo at the Wilderness School, that's about all she remembers) and then guide Piper's hand lower.

"Whoa," says Piper, unable to keep to her own promise, "don't you worry about this, Reyna, I've got you." You don't need to teach me anything, she thinks to herself, and she smirks as Reyna's eyes flutter closed as Piper dances her fingers across Reyna's bright pink.

Yeah. Piper's good at this.

"Just sit back and relax," she says with a grin, and Reyna falls back against the bed, finally letting Piper take charge. Piper pulls Reyna's legs so they hang over the end of the bed – oral is the only thing college dorm beds are good for, really – and starts at Reyna's collarbone, kissing against the soft skin. She makes her way down to her chest, hands gently brushing over Reyna's breasts. She gasps, and Piper grins. If that little gesture gets a gasp out of her, wait until Piper really gets to the good part.

Piper pats Reyna's hips gently, and the other girl lifts her hips to allow Piper to pull her boyshorts down. Piper chucks them somewhere in the room – a bit of payback for whatever the hell Reyna did to her tank top and bra.

"You ready?" Piper asks. "Because I'll make sure you won't be able to answer in a few seconds."

"Just get on with it already," mutters Reyna, her voice surprisingly high and breathy. Piper decides she likes the sound of desperate abandon on Reyna, and makes her wait, just a little bit longer, just long enough to see if Reyna will start begging.

She nips gently at Reyna's inner thighs, and giggles into her skin as Reyna jumps a little bit, not quite used to the feeling.

"Tell me what you like," Piper breathes, "tell me what you do to yourself."

"You're the expert here," whines Reyna, "just do it already," and, as if the next word is drawn painfully out of her, she moans, "please."

That's enough for Piper.

She begins with a firm stroke up Reyna's folds and the other girl nearly flies off of the bed. Piper looks up to see Reyna pressing a pillow over her face.

"Scream all you want," says Piper, "I want to hear you say my name." Piper grins at Reyna's reactions – she's going into this with less reservations than, Piper assumes, everything else. And it would be funny if it wasn't so hot.

Piper continues moving her lips, then her tongue, against Reyna, and her name falling from Reyna's desperate lips is just better encouragement to move different ways, try different things. She's never heard her name sound so good before – it's intoxicating really, and Piper's so distracted as she gets Reyna more and more worked up that she barely hears it when Reyna says, "I'm – I'm –"

The rest of her sentence is drowned out in half a deep exhale and half a moan, and Piper works at her gently through her orgasm. Piper hears her name muttered once or twice as Reyna regains her breathing, like Reyna's trying to talk to her, but she can't get the words out.

She sits up and grins down at Reyna, whose eyes still aren't completely open yet.

"How was your first time?" Piper asks, fighting back a laugh as Reyna's trying to bring her gaze into focus.

Reyna responds with a mindless, babbling string of nonsense.

"I'll take that as a good thing."

Piper's not a jerk, per se, but she's completely wound up after hearing Reyna moan her name, and she's going to have to get this going her damned self if something doesn't happen sometime soon.

"What about you?" says Reyna. "You did me, and now…Oh, screw it."

And then, for the first time ever, Piper's pinned down without expecting it. She struggles a little bit, just to test Reyna's resolve on the subject, against Reyna's grip against her wrists, and she can't move her arms.

Something floods through her, something fantastic, and she grins up at Reyna. "You up for the challenge, newbie?" she asks with a grin.

"Up for anything," says Reyna.

Reyna takes a leaf – no, a goddamned chapter or even an act – out of Piper's book, trying to same moves on her that worked on Reyna, but when it comes to her skill in getting her off, Piper can't complain. It's a little sloppier than what's usually considered effective, and Reyna's clearly trying to do what she's heard other people do, but it works. Piper's yelling nonsense out at the walls (predominantly swears – she hopes nobody on duty is monitoring this hallway, because she knows she gets pretty loud) and at the ceiling, writhing around to the point where Reyna, without a single word, presses a strong arm down across Piper's hips, and Piper can't move anymore.

Piper half hates the fact that someone else is pinning her down, and half is overly turned on and yelling even louder because of it. At one point, Reyna, to Piper's disbelief and discouragement, stops to yell at her about it.

"Would you," Reyna says, looking pissed off from between Piper's legs, "shut the hell up before somebody swings by here and we get written up the first night everyone's here for disturbing the peace?"

"It's your fault," remarks Piper, "and if you'd get back to business we could – mother FUCKER!" Piper arches off the bed as she feels Reyna run her tongue firmly against her. She will never admit it, but she's seeing stars and it's kind of fantastic, especially since Reyna's apparently never done this before.

It takes longer than usual but, somehow, it's better than usual when the wave crashes and her hips arch off the bed and she knocks over whatever the fuck was on Reyna's bedside table.

She's got one hand flung across her forehead and the other draped mostly off the bed when Reyna sits up and sits next to her on the bed, looking a combination of smug and uncomfortable, which is the most bizarre thing Piper's ever seen. She's also got sex hair like Piper's never seen, but she doesn't mention it, mainly because she's too worn out to come up with a decent comment and partly because Reyna's such a newbie she doesn't want to say something to embarrass her.

Instead, she says, "I'd give it a B. Took you a while to earn it, but once you got the idea you were good."

Reyna laughs. "Self assessment would give me an A with the way you were yelling."

Piper snickers. "Don't flatter yourself, newbie," she laughs. "I yell with everyone."

"Bet this is the first time you've ever yelled the name 'Reyna.'"

Piper shrugs. "You've got that one right."

Reyna gets out of bed, leaving Piper still sprawled out on the bed with her hands all over the place and her legs sprawled everywhere. "Where the hell are you going?"

"I'm putting on pajamas, you weirdo, so I'm going to my suitcase."

"How have you not put any of that away yet?"

Reyna turns to her, her face still flushed and pink. "I was reading. You want to make fun of me for that or are you all done with the mocking once you I had you on your back and yelling?"

Piper's silent as she tries to come up with a comeback, and, after a bunch of yelling about reading and how polka dot pajamas are for eight year olds, Reyna tells her that, "I'm going to sleep, so make a decision of what you want to do." So Piper, as a joke, rolls over and pretends to have fallen asleep, just to annoy Reyna.

But then something happens that really, really shouldn't have. Piper must have been exhausted from the day, from the move, from Annabeth, from the party, from Reyna.

She falls asleep.

REYNA

Piper sneaks out that evening around 2. Reyna can tell, because Piper had been looped around her all night, making her way too freaking warm, and then suddenly the feeling of being spooned by a space heater disappeared.

Reyna stays entirely still as she hears Piper stumble gracelessly around Reyna's apartment. She hears Piper utter a, "oh, fuck!" as she crashes into what Reyna assumes is Gwen's sports bag (she can't say she feels too bad about that) and a "where the fuck did that tank top go?" until she grumbles one more time and leaves the room.

She feels weird. Not bad, and not good either. Something's unexpected about what happened tonight, and it might be that Reyna feels a lot more than she meant to.

She rolls over, slightly pleased at the fact that she gets the bed to herself, and dreams about a princess in shining armor she saves from an evil king.

ANNABETH

For being alone most of her first night at school, Annabeth thinks it's working pretty well.

She's made a bunch of progress on her reading and managed to finish Frankenstein for the third time, which is nice, but somewhere in the back of her mind she's kind of disappointed her new roommate didn't come back. She always forgets about time – staying up until 3am reading a book isn't something foreign to Annabeth Chase – but today she's been looking at the clock constantly. It's not that she's worried about Piper, really – she's pretty sure Piper could handle herself for years in the desert with nothing but a spoon and a toucan – it's that she's confused as to why her new roommate wouldn't respond to a text she sent. All she said was, "Got home – hope you have a good night!"

Maybe it was too creepy. Annabeth's good at being accidentally creepy – she doesn't do it on purpose, of course, but she has a tendency to make really weird comments without meaning to. With Luke and Thalia, her friends before she went to the other school, weird and inappropriate comments were pretty much commonplace. She always forgets that it's not okay to make sex jokes around normal people. She also forgets that it's not normal to talk about the mating habits of snails in front of normal people. She puts down the book for a moment and stares at the wall – oh, god, is that why Piper won't text her back?

She has a horrible moment of "well I fucked up," then curls up into reading Mary Wollstonecraft's Vindication of the Rights of Women for her Philosophy of Gender class. It might have been a month and a half before the reading was due, but the topic interested her and she had nothing better to do.

Plus, she already tried to sleep for about two hours and it didn't work.

For some reason, she's too worried about her new roommate.

The words begin to blur about 30 pages in and Annabeth feels her eyes starting to close. She's a little frustrated about being directly in front of the door, but she wasn't going to let that bother her. Besides, Piper seems cool and she has her phone number. The likelihood of her bringing anyone creepy in here is low.

Annabeth also may have programmed the campus safety number into her phone.

Near two in the morning, she decides to get ready for bed. She's still in a bad routine from being at home and sleeping through all of the bullshit during the day. With a big yawn, she stands and changes into her pajamas, bringing her ready-for-bed materials into the bathroom. She hates admitting it, but she's still convinced she's going to get lost in this place at some point and, for the love of god, do all of the hallways have to look the same?

She makes it into the bathroom and gets lost in thought as she brushes her teeth, and when she gets back to the apartment, someone's sitting on Piper's bed.

She halfway nails her leg into the desk which the door clears by maybe four inches and swears a bit.

"Piper, you scared me," she says quietly. "What are you doing here?"

"I said that you shouldn't wait up for me," says Piper, and when she shifts position, Annabeth notices she's not wearing a shirt under her jacket.

"Lose your shirt?" she asks.

Piper, to Annabeth's relief, laughs. "Yeah, actually. You know that girl I was talking to earlier?"

Annabeth's eyebrows rise. "So I'm taking it that you had a pretty good night."
Piper laughs and buries her face into her pillow and Annabeth thinks it might end up being more than one good night. Usually she doesn't think of one night stands making people that happy – or maybe she's just read too much. "Yeah," Piper replies, and Annabeth can hear the smile in her voice, "yeah, it was pretty awesome."

"Well, you know that Carie's going to be knocking on our doors at the crack of dawn to make us do whatever the hell she decides we need to do in the morning to bond with everyone on our floor or something," says Annabeth, cuddling into bed with a kitten plushie she would never admit to anyone she had, "so we should probably get to be soon."
Piper groans and hits herself with her pillow a couple of times. "I know the other roommate would have to be the logical one," she grumbles, "but I hoped you would at least go to bed early enough that it would guilt me into sleeping."

Not sure how to respond, Annabeth simply shrugs. "Guess I'm a disappointment," she says quietly. She doesn't expect Piper to hear, but she does.

"Disappointment?" asks Piper. "Are you kidding me? Dude, you're awesome – at first I thought you were some silent nun thing, but at the party you started pulling out some really hilarious shit and from then on I was fucking sold."

Annabeth turns to Piper and grins. "Glad my inappropriate sex humor entertains you."
"Believe me," says Piper, "you're a better roommate than anything I could have come up with. I just need to figure out a way to compare."

"You made me stop being stupid and shy by being ingratiatingly belligerent about me talking," says Annabeth, quietly enough that Piper could decide not to hear her if that's what she wanted, "that's more than enough."

Piper sends her a grin as she stands up and changes into a pair of boxers and a tank top, not caring a second that she's mid conversation with her roommate. "You know, I think this is the beginning of something great," Piper says with a grin as she throws herself into bed. "But I do have a fairly important question to ask you."

Annabeth can't decide whether or not she should feel nervous. "Alright," she says, "shoot."

"Which is better, Backstreet Boys or *NSync?"

Annabeth thinks about it for a few seconds. "I liked both of them pretty much equally," she says in response, "but if I had to pick someone, I'd say Backstreet Boys because Justin Timberlake was way too much of a frontman for a band that wasn't supposed to have one."

Piper nods. "That is a very good answer," she responds as she throws off the light. "I think we can be friends."
