Lena has always had a rather . . . eclectic social media following.

There were those fans who follow her because she's a Luthor and they expect her to follow in her brother's footsteps. They're her least favorite type of fan- all anti-alien and anti-Supergirl; and she makes a point to block them as soon as they show themselves. She doesn't need that sort of negativity, and neither does Kara. Plus, any sort of contact that reminds her of Lex makes her a little sick to her stomach.

Then there are the fans that have a sort of morbid curiosity about her. Those that are just waiting for her to fall from grace. It's like her life is a real life reality show that people can't help but watch.

She opens her Instagram page, eyes widening when she sees the ridiculous amount of notifications.

Ahh, yes - she had added a picture of her and Kara the other day, and there was nothing her fans loved more than a good couple pic.

It isn't even that ground breading of a picture, they're eating ice cream for Pete's sake. But something about the way Kara's hand is settled possessively around her waist must set people off, because her inbox is full dirty comments, one in particular catching her eye.

"Tell me Lena Luthor doesn't call Kara Danvers daddy in bed."

She's in so much shock that she doesn't even hear Kara creep up behind her.

"Daddy? Why are they calling me daddy?"

She can feel the blush creep up her cheeks and she hears Kara gasp.

"It means something dirty doesn't it?! What does it mean?!"

She forces her eyes to stay locked on the computer screen clicking away from her instagram and onto her email.

"Nothing, it doesn't mean anything."

Silence, and then Kara sits on the barstool beside her.

"I'm going to look it up."

She tries not to wince because surely Kara doesn't know about -

"Urban . . ." Kara says slowly, fingers typing away on the touchscreen of her phone. "Dictionary . . . daddy."

Well shit.

She turns to look at her girlfriend, taking in Kara's facial expressions as she reads.

"Hmmm, well that doesn't sound right. . . How about. . .Oh. Oh! Oh! They think I'm-" Kara clears her throat. "Sexually dominant?!" It comes out as an adorable little squeak that is definitely NOT 'daddy af' but it makes Lena smile nonetheless.

"Well, I mean you kind of . . . look the part." She gestures to Kara's outfit, a blue button down tucked into khaki pants, and yep she could totally see where her followers got the 'daddy' impression.

"Oh! I didn't . . . hmmm." Kara fall silent, and Lena gives Kara her space, patiently waiting until she speaks again, nerves fluttering her voice.

"Is that something- I mean- I could . . . " She trails off, locking eyes with Lena. "Do you want to be dominated in bed?"

She feels a surge of heat at Kara's words, and the strange butterflies in her stomach set off.

"I'm not . . . opposed to being dominated."

"That's not what I asked." The low, almost demanding tone to Kara's voice does nothing to help salvage her panties.

"I - I-" She doesn't know how to say this; how to iask/i for this, but then she remembers that it's Kara, and Kara has never made fun of her ffor anything, and even if she doesn't understand, she won't judge.

"If you were to take control sometimes I would enjoy it."

"Yeah?"

"Yeah."

"Why didn't you tell me before?" Kara's voice is soft, and her hand comes up to cup Lena's chin.

"It's just not something that's come up. It's not important or anything."

Kara's fingers trail down her neck to play with the hair that's escaped from her bun and she shivers.

"If it's something you want, then it's important."

"Well, I didn't know if you would be . . . into it." She coughs lightly and Kara looks downright offended.

"You don't think I can be kinky!"

"What?! No! That's not-"

"It is! You think innocent Kara Danvers can't be kinky."

"I didn't say that!"

"Well, I'll have you know I can totally be kinky."

"Oh, you can?" As soon as she says it, she knows it's a mistake, Kara's eyes darkening and smirk slinking across her face.

"Oh ho! You're in for it now, Princess."

She fights the urge to gulp, her insides quivering under Kara's dangerous stare.

"I need ground rules."

And she knows what the other woman means, but she never really expected to be having this conversation with Kara.

"Ground rules?"

Kara's fingers tug lightly on the lock of hair.

"Safe words, limits." Their eyes lock and Lena does shiver then. "You're having sex with the most powerful being on earth, wouldn't be very smart not to set limits."

She can't really breath, so she isn't sure how she manages to answer; but the word comes out - choked and breathless as it is.

"Pineapple."

Kara's fingers stop their tugging, and Lena can tell she's trying not to laugh.

"Pineapple is your safe word?"

Lena nods and Kara smiles softly.

"Alright, mine's pepperoni."

"Are we seriously using pizza toppings as safe words?"

"Well they're easy to remember! And there's no chance of us actually bringing pizza into the bedroom - unless?" Kara raises an eyebrow and she can't help but laugh at the hopeful look on her girlfriend's face.

"Hard no, I'm afraid."

"So me licking pizza sauce off your tits is off the table?"

"As appealing as you make it sound, I think we may have to stick with chocolate sauce."

Kara's eyes light up.

"And whipped cream?"

"And whipped cream." She agrees and then Kara is back to business.

"Restraints?"

"Please."

"Choking?"

"Uhh, don't actually choke me, but pressure is welcome."

"Strap-ons?"

"Anything in the toy drawer is fair game."

Kara hums thoughtfully at that.

"Spanking?"

"Please."

"Anal?"

"I'm open to a little ass play but nothing . . . extreme."

Kara nods.

"Noted."

"Sex while flying?"

"Sure." She's agrees, because she's a little afraid of flying, but that's kind of the point, right?

"Sex in public?"

"Yes? But don't let anybody actually see us. I don't think either of us want that all over the tabloids."

"I dunno, might be kind of fun - people seeing you all dripping and on your knees for me, begging me to let you come." Kara shrugs, like telling Lena all the dirty things she wants to do to her is the most nonchalant thing in the world. "It would definitely let people know who's in charge."

Kara must see the way she trembles, because her smirk widens.

"Maybe I should have told you about this sooner."

"I might surprise you."

"You always surprise me."

Kara's face softens.

"So whats the signal?"

"Signal?"

"Yea, for me to be all . . . daddy."

"How about I just call you Daddy and then you take over from there?"

Kara looks excited as she leans in for a quick kiss.

"I'll wait patiently for you to call me Daddy then."

It's two weeks before she gets a chance to use the signal.

To be fair, they've been a little busy, L-Corp had some break-ins, and Supergirl had a whole host of alien threats to deal with.

And she doesn't want to just blurt it out during dinner - not the first time, anyway.

So she waits, because she's a little nervous if she's being honest. Not because she thinks Kara will do something she doesn't want, but because she's never been this open with someone, to let them see her vulnerable.

So she waits, until Kara's head is buried between her legs, tongue lapping at her clit. The word slips out, in haze of arousal as she's gasping for breath.

"Daddy!"

She feels Kara's back stiffen under her heels, and a split second later she's flipped over onto her stomach, Kara's weight pressing onto her back.

There's a pillow shoved under her stomach, and her ass is in the air, Kara's voice breathless in her ear.

"Are you sure?"

She barely get out half a nod before Kara is thrusting into her with three fingers.

Her other hand is fisting in Lena's hair, pulling so tight that its should hurt, but it doesn't - it only makes her breath come in short, ragged gasps.

"So close already, babygirl."

She doesn't even try to respond, her brain is too muddled and there's no way she can come up with a coherent thought.

"Mmm. maybe I'll have the heart to make you wait next time, but right now you look so good with my fingers inside of you, and you're so, so wet, baby-"

She whimpers as she comes, and Kara's fingers slowly massage her front wall, drawing out another few shudders.

"That was fast." Kara observes before she presses a kiss to Lena's shoulder blade.

"Sorry." She whimpers half-heartedly.

"Mmm, I'm not complaining. We could have more fun with more time though? Maybe you could call it before I'm three knuckles deep."

"Test run." She moans as Kara's fingers slip out of her.

"And, how did I do?"

"Hot."

Kara rolls off of her.

"Better?"

"No, I mean you're hot, that was hot."

"Yeah?"

"Oh yeah."

Three nights later, they're walking up to Kara's apartment after date night, and Kara looks so . . . fucking attractive.

If Instagram could see her right now then they would definitely call her 'daddy".

She's wearing those back pants, the ones that make her ass look . . . whew. Lena's getting hot under the collar just thinking about it. The sleeves of Kara's button up are rolled up, and her muscular forearms are on full display. That paired with the fact that Kara has been teasing her all night has left her a little needy.

"You're looking good tonight, Daddy."

She never thought the response would be so instantaneous. She thought that maybe once they reached the bedroom, Kara would try something.

The next thing she knows, she's being slammed against the wall.

"Are you feeling frisky tonight, babygirl?" Kara's voice is hot on her ear. "Do you want me to take you right here in the hallway?"

How Lena's IQ goes from Ph.D level to a stuttering mess she isn't sure, (it probably has something to do with Kara's hand creeping up under her skirt), but she can't come up with audible response and instead settles for a whimper.

"Yeah? Is that what you want? You want me to just take you right here?"

Kara's fingers grip her chin, tilting it up until their eyes meet.

"Tell me what you want."

It's a demand, not a question, and Lena shivers.

"I want you to fuck me."

The word are barely out of her mouth before Kara's fingers are inside of her, thrusting and twisting.

"Kara, Kara!" she hisses, nails digging uselessly at her girlfriend's shoulder.

"Shhh, you gotta be quiet, babygirl, someone will hear you."

Kara lifts her, and she wraps her legs around the super hero's waist, groaning as the fingers inside of her hit a different angle.

"Anyone could walk up at anytime," Kara whispers in her ear. "They could see me fucking you. Then they would know without a doubt that you're mine."

Lena whimpers at that and Kara slams into her harder. A third finger is added and she groans at the stretch. Kara's circles her clit and she's almost positive that she's never been this aroused before, because well, Kara's never fucked her in a hallway before. And it isn't Lena's private hallway, where they're completely alone; it's Kara's public hallway, where someone could walk in at any moment. And part of her knows that Kara can hear for miles and that she would never actually let them get caught, but there's also the part of her that knows Kara wouldn't really mind if they DID get caught.

If someone caught Kara Danvers fucking Lena Luthor senseless in a hallway.

She can feel herself building, the delicious precipice just out of grasp. She has no traction to thrust on Kara's fingers, and she's left helpless, her own fingers digging into Kara's shoulder.

"Please." She manages to choke out.

"Please what?" Kara's voice is teasing, and Lena could shoot herself for the monster she's helped create.

"Please make me cum, Daddy."

Kara's fingers double their speed, and Lena feels he head slam into the wall as she lets it fall back.

"Yes! Yes! Don't stop! Don't-"

The hand that isn't between her legs comes up to cover her mouth, pressing just a little too tightly to be comfortable.

"Shhh, babygirl, you have to be quiet."

She nods slowly, but the hand doesn't move; pressing her roughly back into the wall.

It's too much - Kara's hand over her mouth, weight pressing her into the wall, fingers thrusting mercilessly inside of her - it's too much, and she shudders, feeling Kara's lips fall to her neck.

A sharp bite to her clavicle sends her over the edge, and she whines against Kara's hand and her pussy clenches around the fingers inside of her.

"That's it, babygirl, one more time." Kara's fingers are merciless, pounding into her until she feel herself fall over the edge again.

Her brain is a useless pile of mush as Kara lowers her to the ground, non-wet fingers brushing at the wrinkles in Lena's clothes.

A door opens somewhere down the hall and Lena's heart rate doubles.

"Oh, Kara everything all right out here? I heard someone pounding on the wall."

Kara turns, managing to look the picture of pure innocence, despite her dirty persona just moments before.

"Sorry, Mrs. Morgan, I was just killing a fly! Didn't mean to bother you!"

"That's fine dear! Have a good night!" The little old lady closes her door and Kara turns to Lena with a smile on her face.

"Still think I can't be a Daddy?"
