Lena sat in a secluded booth near the back of the club; she was partially hidden from view, but could watch the majority of the bar and dance floor.

She swirled the cocktail in her glass before taking a sip, her blood red lipstick staining the outer edge of the rim as she surveyed the entanglement of sweaty bodies on the dance floor grinding against each other to the music.

This particular club had served as a pick up for the majority of her encounters; it was all too easy for her to find women to dominate, women who were willing and pliant as she drove them to levels of ecstasy they had never known.

But that was before Kara.

Before Kara had willingly submitted to her, before the woman from the stars had allowed her, a mere mortal to graze her fingertips across her body, to become giddy at the knowledge that the most powerful being on Earth craved her touch, just as much as Lena craved the power.

Usually Lena would be eyeing up the dance floor, finding a woman who kept sneaking glances at her before beckoning them over to her booth with a single finger and a raised eyebrow. However, she found herself perfectly content to slowly sip her cocktail and soak in the sexually charged atmosphere.

Lena watched as the group of people by the bar parted, revealing a blonde in a sinfully tight sleeveless black dress and heels. It takes a few moments for Lena to register that the woman is Kara, having never seen her in anything that provocative. Her hair was down, but she has kept her glasses on and her make up was darker than usual.

Kara scanned the crowd from the bar, she knew Lena was here, she had picked up the CEO's heartbeat flying over National City. She spotted Lena in a booth towards the back of the room, and looked the other woman up and down before looking back to the dance floor. She didn't acknowledge Lena; she wanted her to squirm, to beg. She smirked as she turned back towards the bar, her eyes flashing purple for a second as the effects of the periwinkle krytopnite coursed through her. She flagged down the bartender and placed her order; she was well aware of the effect she was having on Lena, she could hear the spike in her heart rate.

Lena saw Kara scan the room, her eyes running over her body, but no acknowledgement, no sunny smile or flustered blushing. She watched Kara turn back towards the bar and lean over to talk to the bartender; the material of her dress tightening over her arse and riding up slightly. Lena wanted to sick her teeth into the flesh and briefly pondered the reaction of the other patrons if she was to take Kara over the bar; if she was to push up Kara's dress before sliding two fingers into her soaked folds as Kara gripped onto the bar, if she was to sit on the bar and push Kara to her knees and instruct her to lick her. She quickly dismissed the idea; she wasn't really into overt exhibitionism.

With two drinks in her hand, Kara slowly sauntered over to where Lena was watching in the shadows.

'Ms Luthor' Kara greeted, her voice deeper than usual as she slid the martini glass in front of Lena.

'Kara' Lena responded, still unsure as to what dynamic was currently in play.

'You look good' Kara smiled as her eyes roamed Lena hungrily, taking in the slightly more relaxed attire of the CEO; her hair tied back, the front sprayed into a high quiff, the waistcoat with gold buttons with nothing underneath, the lace from her bra peeking through. Tight slacks and heels completed the look.

Kara couldn't wait to rip them from Lena's body, to have Lena sweaty and writhing beneath her, utterly wrecked.

'You took the words right out of my mouth' Lena smirked as she leaned back, taking in the flexing of Kara's biceps and the predatory look on her face.

Kara's tongue poked out to wet her lips as she contemplated how she wanted this evening to end. In truth there was only one option; she had given herself over to Lena, now it time for Lena to become hers.

'Dance with me...' Kara demanded as she held out her hand to Lena.

Lena took Kara's hand as she stood and allowed herself to be pulled towards the dance floor. As a general rule Lena usually stayed in her booth, preferring to use her body language to flirt and make the women she desired come to her; it was a power move she had perfected over the years.

Kara led her to the middle of the floor among the gyrating hips and roaming hands before pulling Lena into her and snaking her hand to press against Lena's lower back.

Lena let out a slight squeak in surprise as she found herself flush against Kara. She saw the sparkle in Kara's eyes at the surprise and decided that Kara was toying with her, pushing the boundaries of their unspoken agreement.

Deciding she needed to regain the upper hand, Lena placed her hands on Kara's hips and tried to spin her around.

'Uh uh. Not tonight Ms Luthor...' Kara chastised and removed Lena's hands.

Lena looked into Kara's eyes, wondering what could have spurred Kara into acting so boldly and saw the flash of purple; she immediately stepped back with a slight hint of fear on her face.

'Don't worry, I haven't been exposed to Red Kryptonite' Kara chuckled as she read the look on Lena's face, 'it's a different kind that lowers my inhibitions; makes me more… assertive, makes me want you quivering beneath me.'

Lena stepped back closer to Kara, running her fingertips up Kara's arms before cupping the back of Kara's neck and pulling the superhero closer to her.

'And what makes you think you get to be in control?' Lena husked as she sucked Kara's earlobe between her teeth, 'this isn't how this works Ms Danvers.'

'Because it intrigues you, to lose control, to surrender to another' Kara lowered her mouth and bit into Lena's neck, soothing the red flesh with her tongue.

Lena whimpered and Kara smirked; she would have Lena begging beneath her before sunrise.

Lena had to admit Kara was right; no one ever saw past the Luthor name, the power she wielded because of it, the tight skirts and the heels. It was assumed that the Luthor would be in control, so she played the role and discovered a raw enjoyment for it, but handing over the control she had perfectly maintained for so many years? That thought scared her a little.

But with Kara? Kara was safe and Kara wouldn't hurt her. She pushed out all thoughts of what else she wanted Kara to be and focused on moving her body in time to the music.

Kara spun Lena around so that her back was flush to her and placed her hands on Lena's hips, moving them to the beat. Kara's hands roamed Lena's body occasionally brushing under her waistcoat at the top of her stomach, accidentally brushing higher to graze over Lena's hardened nipples. Lena groaned slightly and pushed her arse back into Kara, grinding against her centre, eliciting a small moan from the Kryptonian.

Kara's movements became bolder; she nipped at Lena's neck as one hand slid lower and lower until it reached the waistband of Lena's slacks. Her fingertips dipped below the material and she felt Lena stiffen in her arms.

'No one is watching' she purred in Lena's ear, 'they're all too busy drinking or thinking about fucking each other to notice us...'

Lena glanced round and saw that Kara was right; no one was even looking their way. She relaxed slightly and let the music and the feeling of Kara's fingers wash over her.

Kara slid her hand below Lena's slacks and gently rubbed Lena's centre through the lace of her panties.

'You're already so wet for me...' Kara murmured in awe as she slowly teased Lena, who's head fell back to rest against her shoulder, 'as you enjoy setting rules for me so much, let me lay out a few of my own. You make any sound and I stop. Understood?'

She saw the slight nod of Lena's head in agreement.

'Answer me' Kara demanded.

'Yes' Lena whispered out.

'Yes what...'

Lena bit her lip, unsure if she could actually say the words; she knew Kara was playing her, just as she had teased and played Kara the previous week. She felt Kara's grip on her hip increase beyond a level that would be considered human as the fingers on her other hand lightly glided over her clit.

'Yes what...' Kara probed again.

'Yes, Ms… Ms Danvers...' Lena whispered out, Kara's super hearing picking up the words.

'Try again' Kara chuckled as she starts to remove her hand.

Lena breathed in heavily, racking her brain for what Kara wants to hear, when suddenly-

'Yes Supergirl!'

'Good girl' Kara growled as she slides her hand back down and underneath Lena's panties this time, 'remember what I said; no more sounds.'

Lena nods and turns to bury her face into Kara's neck to stifle her moans as fingers circle her clit.

Lena brought one arm up to tangle her fingers into Kara's hair as Kara rubbed her clit in time to the music, in time to the beat that was vibrating through both their bodies.

Kara slipped two fingers into Lena, who bit into Kara's shoulder to keep herself from moaning out. Kara chuckled as she moved her fingers at a ridiculously slow pace, waiting for Lena to whine in response. She could feel how deeply Lena was breathing and it was only a matter of time before she broke the one rule Kara had set out.

Lena huffed; she knew exactly what Kara was waiting for- this was payback not not letting her come after she broke the bed. The low chuckle she heard from Kara confirmed her suspicions. There was no way she was letting Kara win.

Lena rolled her hips in an effort to get Kara to thrust her fingers quicker and deeper, but quickly found that she was unable to move, Kara having moved her hand from Lena's hip to rest across her stomach, pinning her in place.

Kara continued at the slow pace for a few minutes before suddenly curling her fingers. A moan escaped from Lena before she could stop it and Kara immediately removed her fingers, smirking triumphantly.

'I warned you Lena' Kara purred as she brought her two fingers covered in Lena's arousal up to her mouth. She wrapped her tongue around the digits and sucked them clean while Lena clenched her thighs together and tried to regulate her breathing. 'Send a message to your driver' Kara demanded as she pulled Lena to the secluded corner she had spotted.

Lena sent a quick message for Leonard to come and collect her along with the address before placing her phone back in her pocket. She quickly found herself pushed up against the wall, Kara's thigh between her legs as Kara's lips roamed her neck, nipping and sucking, leaving a trail of reddened marks in her wake.

'Now you're going to have to wait before I let you come' Kara interjected between kisses, 'it's not my fault you couldn't follow the rules...' she added at Lena's whine.

'Kara...' Lena panted out as Kara teasingly brushed her nipples through her waistcoat, rocking against Kara's thigh trying to cause some friction to relieve some of the pressure that had built up.

'No!' Kara growled out as her eyes flashed purple, 'we're not playing by your rules this time Lena. You belong to me. Understood?'

Before she could reply, Lena felt her phone buzz in her pocket signalling Leonard was waiting outside. Kara placed a bruising kiss to Lena's lips and then took her by the hand, leading them both out into the cool air.

Kara spotted the black Mercedes and walked over to it, her heels clicking on the ground. She opened the door and climbed in.

'Hi Leonard, you may want to put the partition up and turn some music on...'

Leonard simply pressed the button to raise the partition, his facial expression never changing.

Kara smiled and settled back against the leather of the seat and kicked her heels off just as Lena's head came through the door.

Lena noted the closed partition between the seats and her driver and raised an eyebrow in question as she sat down onto the cool leather next to Kara.

'I don't know why you've sat there' Kara questioned playfully as she placed her hand onto Lena's shoulder and pushed down gently, 'I think you'd look much better on your knees... between my thighs...'
