Rehydrate yourself & save Louise

You stumble up into the light and sound of the party, still popping off despite the late hour. There are still folks dancing away under the black lights, a dude cradling a bucket laying out on the couch, clearly miserable, and folks still milling about and talking.

You step out into the kitchen, grabbing another ready-filled cup and downing it at once, wetting your parched throat. You gasp, then stumble over to the kitchen sink to refill it with actual water. As you stand there, sucking down fluids, you notice Louise of all people, backed into a corner of the kitchen, a crowd of frat bros, clearly just as piss drunk as you, gathered around her like hungry animals. She looks to be backing herself up as much as she can, clearly uncomfortable with the intensity of their attention. She spots you, flashing you a worried smile and a little come-hither wave.

You slide up next to Louise, feeling her arms wrap around your waist and cinch tight. She leans into you, clearly relieved. "Hey babe," she says loudly, playing it up. "I was just telling these guys about my amazing boyfriend." She looks up at you, eyes pleading to go along with her ruse.

“Oh,” you reply, a little surprised but nevertheless wrapping your arm around her waist and pulling her tight against your body. “Yeah, uh, babe,” you add, the words feeling alien and wrong to use to describe your sister.

The frat bros shuffle about, clearly frustrated and annoyed at your sudden interloping into their little circle around Louise. You notice they are wearing the shirts of a different fraternity, which only increases your suspicion of them and their intentions with her.

That suspicion is a two way street, based on the mug that the especially a tall, beefy bro sporting a soul patch on his chin and wearing a backwards baseball cap who seems particularly drunk and ****. "You two are dating, huh?" he slurs. "How long you been together, huh?"

Louise looks at you, letting you take the lead on the story. You grin and pull her closer. "A long while now. Since high school. Isn't that right, babe?"

She nods enthusiastically. "Yep, feels like I’ve known him forever! He's the best."

The bros seem disappointed but don't back off right away. “Are you sure bro? Are you really sure?” The one with a soul patch asks.

“That she’s my girlfriend?” You scoff, “of course, she’s mine.” You feel her tense in your grasp, either out of genuine or feigned embarrassment, you can’t tell.

“I don't know bro,” the soul patch bro continues, clearly unimpressed, “what’s the babe’s name bro?”

“It’s Louise,” you snap back at him. You feel a heat rising in your chest. Anger, perhaps, at this frat bro for calling your sister turn pretend girlfriend ‘babe,’ and you pull her a little bit tighter against you. “And she’s my babe,” you add.

Louise suddenly perks up as the music changes tracks. "Oh, I love this song! Let's go dance, babe." She grabs your hand and starts pulling you toward the dance floor, the frat bros reluctantly parting to let you through.

The frat bros follow at a distance, continuing to hover nearby as you and Louise start dancing together. The song is slow and romantic. You slide your hands around Louise's waist as she presses against you. She looks up at you with a mischievous glint in her eye.

“Since when did you learn to dance?” she giggles. You can smell the **** on her breath.

“I took the same PE unit on it as you did in high school,” you reply, giving her a grin. You see her look over your shoulder where you can sense the frat bros lurking.

"I think this guy is gonna try to cut in and ask to dance with me," she says without a hint of humor. You tilt your head to the side and out of the periphery of your vision you can see soul patch and snapback bro approaching. "You better make this look convincing!" With that, she wraps her arms around your neck, leans in, and starts making out with you, kissing you deeply.

For a moment you are shocked stiff as Louise, your own flesh and blood sister, makes out with you like her life depends on it.

Then you kiss her back, one hand roaming lower to grope her ass through her tight skirt. To complete the pretend act of course. In response, she grinds forwards against you, putting on a show. You get lost in the moment, enjoying the feel of her lips on yours, her body pressed flush against you. Her lips are hot and wet, and although you can taste ****, she still tastes sweet and soft. You feel the curve of her shapely behind through her dress, marveling at the softness and warmth of her flesh. That recurring image of her, wrapped in thin robes of gossamer and silk, ready to retire to a waiting wedding bed flashes across your mind.

Eventually you break the kiss, both of you averting your gaze as you silently go back to slow dancing.

It isn’t until after the song ends you notice the frat bro that had been spoiling to get in between you has finally given up and moved on to bother some other poor girl. Louise pulls back, flushed and laughing. "Guess he finally decided to buzz off. Some 'boyfriend' I've got, feeling me up like that." She swats at your chest playfully.

You grin and shrug, “Hey, I’m just playing my part."

“Sure babe,” she laughs, “just glad that those guys finally got the hint," Louise says with a laugh as you two continue dancing. "You really saved my ass there, boyfriend. Those guys were getting super pushy."

She spins around in your arms, grinding her ass against your crotch as the music picks up pace. You try to focus on the conversation and not the feeling of her soft curves rubbing against you.

"So how are you liking the party so far? Must be a nice change of pace from work and classes, huh?" she asks, looking back at you over her shoulder with a grin.

You smile back at her, your hands roaming over her hips and sides as you dance. "Yeah, it's been great so far. Well, aside from the whole Tatiana debacle earlier," you say with a grimace. "But having you as my pretend girlfriend is definitely making up for it."

Louise laughs and shakes her head at your mention of Tatiana. "Ugh, that girl. I love her to **** but she can be such a drama queen sometimes. Forget about her for tonight, I'm your ‘girlfriend’ now, remember?" She winks at you teasingly, turning around to dance facing you again.

You grin back at her, giving her ass a squeeze. "Oh I definitely haven't forgotten, trust me. Best ‘girlfriend’ I've ever had." You chuckle.

She scoffs and reaches back to swat at your roaming hands again. "Boyfriend" she says warningly, but there's no real heat in it. If anything she seems to be enjoying all the attention, if the flush in her cheeks and the way she keeps pressing back against you is any indication.

The two of you continue dancing and talking, falling into an easy banter like you always do. It's nice, almost making you forget the weirdness of the situation. Almost. Louise may be your sister but she's still fun and a relatively attractive woman. And with the **** coursing through your system, you're finding it harder and harder to ignore that fact.

Out of the corner of your eye you see a girl approaching cautiously, eyes locked on you. Your eyes unconsciously travel up her frame; she’s blonde, busty, and blue eyed with a blush that goes across her face, down her neck, until it disappears in her ample cleavage. With your third eye you can see clearly see a grey light around her hips, that she's also on birth control. When you meet her eyes she grins at you.

“Heyyy,” she says, trying to dance her way between you and Louise, “care to dance?” she asks you.

“I―” you don’t get to finish your sentence before Louise butts in.

“Hands off, he’s my boyfriend!” She snaps, pulling you tight against her in the process. The busty girl pouts but backs away, throwing one last longing look your way before disappearing into the dancing crowd.

“Aggressive, much?” you say, flashing a grin at Louise.

“Shut up, I’m just protecting my ‘boyfriend’ from wandering hussies,” she replies, going up on her toes to give you another peck on the lips.

At one point Louise dances on you, arms around your neck as she grinds against your thigh. "You know," she says, pitching her voice low under the music. "If I didn't know better I'd say you were actually enjoying this. Being my ‘boyfriend’ I mean."

You swallow hard, trying to play it cool. "Well I'd be lying if I said I didn't like having an excuse to put my hands all over you," you joke weakly.

Louise just smirks knowingly. "Mmhmm. Well you better not be getting any ideas, mister. I may be your girlfriend for the night but I'm still not gonna let you cross any lines, capiche?"

"Of course," you assure her with a smile, holding up your hands. "I would never. Platonically feeling you up is as far as this goes, I swear."

“What a gentleman,” Louise snorts, but makes no moves to stop you, seeming to revel in the attention and the affection you're giving her.

After a while of dancing and chatting with Louise, the party starts to wind down. People begin trickling out and the music lowers to a more reasonable volume. You and Louise take a break from the dance floor, both of you sweaty and out of breath.

"So," she says, fanning herself with her hand. "I think I'm about partied out for the night. You want to come back to my place? I've got a couch you can crash on."

You hesitate for a moment, weighing your options. On one hand, going home with Louise could be complicated, given everything that's happened tonight between you and Tatiana, and now you and Louise. But on the other hand, you're not exactly in any state to be making the trek back to your own dorm right now. And the thought of spending more quality time with Louise, even ‘platonically’, is definitely appealing in its own right.

"Yeah, sure," you say finally, giving her a smile. "Lead the way."

Louise grins and takes your hand, leading you out of the frat house and into the dark of the night. The walk to her apartment is pleasant, the two of you swaying and laughing together. The night air is cool and refreshing after the sweaty heat of the dance floor. Between the different houses on Greek Row, it's clear that most of them are still partying strong, despite the late hour. Cups and bottles and cans litter the street and sidewalk. Here and there are a few partygoers, still either coming, going, or going in the bushes as discretely as possible.

"So," Louise says, looking up at you with a tipsy smile, "have I been a good girlfriend tonight?"

"The best," you assure her, sliding an arm around her shoulders. "I'm gonna have a hard time going back to the reality of having an annoying older sister after this."

Louise laughs. "Yeah, I'll miss being your girl. Even if you are a massive perv." She pokes you in the side playfully.

You capture her hand and lace your fingers through hers. "Hey, I just appreciate the female form, that's all. Especially yours."

Louise rolls her eyes fondly. "What a charmer. You should save some of that for the ladies." She yawns then, covering her mouth with her free hand.

She stumbles a bit and you catch her easily, your hands on her hips. She looks up at you, her eyes dark and hazy with drink and something else that you can’t quite place. Something ancient and powerful and unknown that makes you swallow hard.

"My hero," she murmurs, before rising up on her toes to kiss you again.

This time, it's slow and deep, tongues tangling lazily. You can taste the **** on her breath, but underneath is the sweet, addictive taste that you can’t find a word for. You feel your cock twitch in your jeans, starting to harden again. Louise feels it too, and rocks her hips against yours, just once, before pulling back.

"Let's go," she whispers, and leads you off into the night, hand in hand.

The two of you stumble into Louise's apartment, still giggling and leaning on each other. The place is as you left it, small but cozy, now with the coffee table covered with leftover drinks from the pregaming you did. Louise kicks off her shoes and pads over to the couch, pulling you down with her.

"Okay, little brother," she says, poking you in the chest. "You've been a very good boyfriend tonight. But now it's time for bed now." She yawns again, stretching her arms above her head. The movement makes her tits strain against the fabric of her dress and you can't help but stare.

"Oh? Like what you see?" Louise teases when she catches you looking. She leans back on the couch, thrusting her chest out invitingly. "Maybe if you're good, I'll even let you touch them again."

You grin and lean in, pressing a kiss to the curve of her breast. "I'd like that," you murmur against her skin. "But only if you want me to."

Louise shivers and runs a hand through your hair. "Well, since you asked so nicely―" She guides your hands to her tits, letting you squeeze and caress to your heart's content. They feel weighty and firm in your hands, the underwire of her bra doing its best to hold them up.

The two of you make out on the couch for a while, hands roaming and bodies pressing close. You lose yourself in the softness of Louise's curves, the heat of her skin through her dress. Your cock is rock hard in your jeans but you don't try to take things further, content to just enjoy this moment with your sister.

Eventually Louise pulls back, cheeks flushed and eyes bright. "Okay, that's enough for tonight. You're gonna make me do something I regret if we keep this up." She stands up on wobbly legs, smoothing her dress down.

You pout but don't protest, settling back against the couch cushions, cock throbbing.

Louise smirks and leans down to give you one last kiss, slow and filthy. "Don't worry, I'm sure you'll find some way to take care of it on your own if you need to."

Then she is sauntering off to her room, hips swaying.

You watch her go, licking your lips and adjusting yourself. It takes a long time for your cock to calm down enough for you to sleep.
