Now back to dancing with your sister

Meanwhile, downstairs and out on the dance floor you see a girl approaching you and Louise 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 between 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.
