"Knock, knock!" Alex said loudly as she pushed open the door slightly, but not widely enough to be able to see inside.

"Alex! What are you doing!" Kara exclaimed angrily, before using her superspeed to wrap herself in a sheet, "You know we're not supposed to see each other before the wedding!"

"I know, but it's a stupid tradition, and an earth one, so why do you care?" Alex whined petulantly.

"I care because we need all the good luck we can get." Kara reminded her, "I mean, Supergirl gets married? That's just begging for something to go wrong. Why would you want to risk that?"

"Because it's how things began for us." Alex exclaimed loudly, before sighing and explaining herself, "You probably don't remember this, but when I first got inside your head, when the Black Mercy was trying to kill you, there was no one around. But then I found you, and you were mad because it was just before the wedding, but you were so, so happy to see me. You walked right up to me, took me in your arms and kissed me, and that Kara, that is how I found out that you had been hiding your feelings for me. Before that I was oblivious, but you kissed me, and it was scary and confusing, but I didn't pull away, because even then I knew it was right. It felt good. Like it was always meant to be that way between us."

There was a long silence and then Kara softly said, "I remember."

"You do?" Alex frowned.

"Alex, how could I forget anything about the greatest day of my life." Kara said, sounding offended.

"Oh." Alex smiled, before using this to make her point, "So, so maybe it's the opposite for us, you know? Maybe seeing each other before the wedding is a good thing?"

There was more silence, this one brief, before Kara pointed out, "I wasn't really marrying you, everything about that wedding was fake and an evil plant was slowly killing me."

Both girls chuckled softly, then Alex pointed out, "And you said it was the best day of your life?"

"It was! You returned my feelings." Kara argued, "Do you have any idea how awkward it would have been if you didn't? I still have nightmares about it Alex, and the only thing that makes it okay is waking up in your arms."

"Yeah, but I did, and let's face it, we're in danger of something going wrong anyway, so why not say to hell with it and promise each other were getting married today no matter what?" Alex said boldly, before sighing and counter offering, "Or if it really bothers you, how about a compromise? I close my eyes, you close yours, and we open this door and just kiss?"

There was a long pause and then the door slowly opened and after exchanging a shy smile with her soon-to-be wife Kara softly murmured, "Or..."

Kara and Alex Danvers then simultaneously moved to close the distance between them, wrap their arms around each other and press their lips together in a kiss straight out of the end of one of those romantic comedies which Kara had always loved, and Alex loved just as much even though she pretended not too. And it was perfect. Especially unlike last time they had kissed before their wedding, the fake one, Alex didn't hesitate even for a second.

No, Alex pulled her close and kissed Kara with everything she had, making the Kryptonian's heart flutter in her chest, because again it was so, so perfect. Maybe too perfect, Kara even more nervous that something would go wrong after this, and yet somehow reassured, if this kiss proved anything it was that Kara and Alex loved each other, and would get married one way or another.

Thankfully they were officially announced as wife and wife, and had a similar happy ending to romantic comedy kiss which was just as perfect, before they were interrupted by the usual superhero shenanigans, but who needs a boring wedding reception when you could be fighting alien invaders? Which was admittedly a struggle, but it was all in a day's work for Supergirl, and she even got a piece of the mostly intact wedding cake.

Okay, maybe more than a piece, but Kara needed energy for the honeymoon, and before that her wedding night. The wedding night which she had always dreamt of but never truly thought she'd actually have. The one where Alex would be pressing her up against the door of their honeymoon suite frantically making out.

Once the door was unlocked Kara broke the kiss and insisted, "Wait!"

"What?" Alex frowned, before an evil grin crossed the other woman's face, causing her to protest, "Kara no... NO! Ah, seriously put me down!"

Kara had of course picked Alex up bridal style and was in the process of trying to walk her over the threshold before she seriously started protesting, making the mighty Supergirl pout, "Awww, but Alex! It's traditional."

"It's embarrassing." Alex grumbled.

"Please?" Kara gave Alex her best puppy dog eyes.

"Fine." Alex sighed after a few long seconds trying to resist, "But you owe me."

"Oh, I'm more than okay with that." Kara grinned wickedly, slowly crossing the threshold and then gently kicking the door closed behind them, "Here, let me make it up to you."

With those words echoing in the air, and a grin still very much on her face, Kara gently floated into the air, got into her more traditional flying position, and then flew her way to the bedroom. Alex honestly tried not too, but she giggled at these antics, obviously charmed by them, which made Kara feel very proud of herself.

Flying together had been a favourite pastime ever since they were kids, and it always put a smile on Alex's face, regardless of how much they did it. Although now that frequently lead to sex, often while still flying in the air, so to enhance sexual tension which was already there between them. Hence why Kara went straight for the bedroom. Well, one of the reasons.

Given that it was their wedding night, and Kara had pretty much been in love with Alex since day one, there would have been sexual tension between them anyway, but this was the perfect thing to put them in the mood, and Kara couldn't help but make it last. Which included floating as slowly as possible to the bedroom, and then once she reached her destination if possible slowdown even more, and then hovered over the bed for a few long minutes.

To be fair as soon as they were hovering over the bed Kara gently brushing some hair behind Alex's ear and then they gently melt into another long kiss, but still. Then Kara pulled back and smiled dreamily down at the woman who had just made her the happiest girl in the whole wide world.

Alex was happy too. More than she could possibly have ever imagined, maybe especially when she had first met the teenage version of this alien. She hadn't known it at the time, but Kara had an enormous crush on her, and didn't know how to deal with it, which made her no fun to be around. And, well, they had both been going through puberty, and stuck together under the same roof pretending to be sisters, so it wasn't exactly surprising they hadn't got off to the best start.

But now here they were, starting their new lives together as a married couple, and Alex just wanted to live in this moment forever. So much so she wasn't even in a rush to have sex. But from looking Kara's eyes she didn't agree with that, and just wanted to ravage her, which would be appropriate. Along with something else which was the norm for them.

"Can we take it slow tonight?" Alex asked softly.

"Of course, whatever you want honey. I was just about to suggest the same thing." Kara babbled like the lovesick fool she was, then when Alex gave her a look she blushed and admitted, "Okay, maybe not, but you're right. I want this to be special."

"It's always special with you." Alex smiled dreamily, before realisation hit, "Oh God, did I really just say that?"

"Yeah." Kara giggled, her inner little sister shining through, "And I'm not going to let you forget it."

Alex asked, and then relented after deciding she deserved some mockery for her sappy words, "Okay, but just don't tell anyone."

"I promise." Kara swore unconvincingly, before more convincingly admitting, "But I want it to be extra special too. And it will. I know it. It's us."

"I know." Alex said softly, before ordering, "And you can start by putting us down."

"Awww, Alex!" Kara whined.

"Now!" Alex pushed firmly.

"But this is kind of our thing." Kara pointed out, and then when Alex gave her a look she simply sighed and did as she was told, "Fine! Better?"

"It will be, once I get you out of that dress." Alex grinned, kissing Kara again.

Which caused both girls to grin against their latest kiss before becoming lost in it. Admittedly that wasn't the plan, but in their current state it just couldn't be helped. They were just too eager to share that small intimacy, and to be fair it was all part of taking things slow, which was exactly what Alex wanted.

Sadly they would be inevitably forced to break that kiss, because while they normally removed each other's clothes while kissing that led to a lot of rips clothing, especially when super strength was involved, and they didn't want to ruin their dresses. Which was also why Alex had made it very clear to Kara they wouldn't be having sex until they were removed, although she somewhat regretted that order now they were faced with actually removing the dresses.

It had been difficult enough getting into these frustrating contraptions, Alex quickly remembering why she almost never wore a skirt or a dress, always preferring a nice pair of pants. Pants were always easy to remove, or slip into, but these things? God, Alex actually kind of wanted to rip hers it was so fiddly.

But surprisingly Kara showed tremendous restraint in taking it off, and her own. Perhaps it was because she was more into keeping these things intact than Alex was initially guessed, or maybe it was just part of Kara wanting to make this night special. Either way Alex was very doubtful when they were down to their underwear, which was a lot easier to remove, and something they could do while kissing.

Before their lips came together again they did take a few long moments to enjoy the sight of each other the moment after they removed each other's wedding dresses, and perhaps more importantly they pulled apart so they could get a good look at each other completely naked. It was something they had both seen countless times, but Kara never failed to take Alex's breath away, and vice versa.

God, how was there a time Alex hadn't seen Kara that way? She had literally been living next to a goddess, and she had wasted so much time treating her like an annoying little sister, when they weren't even the same species. Although to be fair Alex had been ridiculously sexually repressed back then, but still, on some level she had to have been in love with Kara, right? Surely there was an explanation for why she felt so intensely for another person now.

Kara was very much feeling the same intensity as she gave Alex a bashful smile, and then their lips once again came together. Which might have been her favourite kiss tonight so far, because it involved them both moaning as their now naked bodies pressed against each other. Their hands weren't even sliding over each other yet, but just the feeling of skin on skin was so intense in that moment it filled Kara with pure bliss.

Of course it wasn't long before lust got the better of them both, and while they were obviously trying to be good and avoid each other's most sensitive areas it wasn't long before they were groping each other like teenagers. Which led to Kara pinning Alex down and starting to kiss her neck, only to be stopped by the other girl.

"Kara wait!" Alex gasped.

"What?" Kara whined in annoyance, before a horrible thought came to her, "Oh my God Alex, I didn't hurt you, did I? Oh Rao, I'm so, so sorry. It's just that, I'm so excited, I don't know my own strength, and I'm so stupid, and-"

"It's alright Kara, I'm fine." Alex insisted, and then when the other girl gave her a quizzical look she explained, "I just want to go down on you first."

"Oh." Kara said, before quickly adding, "I wanted to go first. To lick you first, I mean."

"I know..." Alex smiled, and then to avoid this argument, like the type they had when they were teenagers, she suggested, "How about we both do it?"

"You mean..." Kara grinned brightly.

"A 69? Yeah." Alex grinned.

"I call bottom!" Kara squealed childishly.

"Okay." Alex sighed, "But I get to do foreplay first."

"Deal!" Kara beamed, quickly lying down flat, "Foreplay away, Mrs Danvers."

Unable to help herself Alex smiled gleefully and returned the corny line, "As you wish, Mrs Danvers."

As much as it was clear that Alex hated herself for being so sappy Kara loved every second of it. It made her heart flutter to hear the bad ass Alex Danvers use such language, and smile at her like that. Rao, she used to pray that someday Alex would smile at her like that, and now finally her prayers had been answered.

In more ways than one, Kara's heart very much fluttering as the woman she loved got on top of her and started kissing her neck and gently sliding her hands all over her. Oh yes, this was literally the stuff of her teenage dreams, and the reality was even better. Sure, she could have done with some more thorough attention sooner, but at least for a while Kara was content with this gentle treatment.

Thankfully Alex did eventually pick things up a notch by kissing her way down to her boobs, worked her way up one and then took a nipple into her mouth. She then swirled her tongue around it gently, before sucking it just as gently, both of which made Kara cry out joyfully.

Alex then lingered on that nipple for a few long seconds, before kissing her way down that nipple and then working her way up the other to give that nipple the same treatment, much to the delight of both girls. It certainly got similar reactions out of Kara as Alex started repeating the process over and over again, cupping each of her tits more firmly into her mouth while using her free hand to play with the other one as she did so.

Which was wonderful, but it wasn't what Kara wanted most right now. Well, she kind of wanted to be the one teasing Alex instead of it being the other way around, but Kara found it hard to complain first because her beloved girlfriend was just so good at this. Her wife! Alex was her wife now, Kara reminded herself with a dreamy smile, that wonderful thought able to distract her for a few long seconds.

But it also made the desire for more even stronger, to the point where she was opening her mouth to complain. Thankfully before a single sound could get out Alex gave her what she so desperately wanted in that moment, namely the privilege of pleasing Alex more directly.

Alex did her best to make gentle, slow love to her new wife, but as much as she wanted to do that all night long she knew how impatient Kara could be, and more importantly how eager to return the favour she would be, so it was important to strike the right balance between giving the other girl all the love and attention that she wanted to give her, and to give Kara what she wanted.

Which wasn't always the same thing, unfortunately, so as much as Alex wanted to spend longer on those pretty little titties she gave Kara just as much as she thought the other woman would want before signifying that was done with a kiss, Kara quickly and eagerly returning it.

The quickness and eagerness Kara showed told Alex that her 'sister' turned wife was now very ready for more, and while Alex very much wanted to be the one who's tongue touched pussy first, it wasn't exactly a chore to sit on Kara's face, especially when she knew just how good her lover was at eating pussy. So after a far too brief kiss Alex positioned herself over Kara's face and slowly lowered herself downwards, until she found herself crying out in pleasure at the first touch of Kara's tongue to her twat.

Which came far sooner than she was expecting it, although she really shouldn't have been. After all, wasn't she just thinking about how impatient Kara was? So of course it was totally predictable that the other girl would lift her head up and start licking her before she was even properly sitting down.

It was predictable, but it was also wonderful, Alex just staying there for a few long seconds and savouring this wonderful moment as Kara eagerly continued licking her. Then she very slowly lowered her lower half down so that she was literally sitting on Kara's face, albeit while supporting most of her weight on her knees so she wasn't preventing Kara from breathing.

After all, even Supergirl had her limits, and Kara tended to get so lost in eating Alex's pussy that she forgot to worry about things like getting enough oxygen, leading too a few almost humorous occurrences. But Alex did her best not to think about that now, and just savour the first time that her wife Kara Danvers ate her out.

Not that long ago it wasn't a big deal Kara had her last name, because growing up that's the way it always was, meaning to get married Kara had needed to change her name, so she could become Kara Danvers again, only this time, it meant that she was Alex's wife and not her adopted sister, although in this moment she couldn't forget about that fact.

The way they had started out life, not by their choice, but by the choice of Alex's Mom, and to be fair circumstances out of anyone's control. And now here they were. On their wedding night, Alex riding Kara's pretty little face, and about to 69 with her. It wasn't exactly what Alex had envisioned, but somehow it was perfect, something she savoured for a few long seconds, before lowering her upper half down, and completing the 69.

Kara would have been perfectly happy to remain the one giving pleasure for much longer than that, as there was nothing she liked more than having Alex Danvers sitting on her face. This meant that her whole world became consumed by the woman she loved, as it was all she could see, smell or taste. Well, if she really tried she could use her powers to smell or see other things, but why would she?

It would ruin such a perfect moment. Which was why she did her best to restrict her hearing to the wonderful sounds Alex was making, only occasionally listening out for trouble while otherwise consumed by the moans, whimpers and cries that her lover was letting out while she pleasured her.

Of course she would be lying if she tried to claim she didn't welcome the moment that she felt Alex's talented little tongue sliding across her pussy lips for the very first time during that extra special night. During their wedding night! Oh Rao, it was their wedding night, that thought causing almost as much pleasure to echo through her body as the first long slow lick that she received.

It was so powerful in fact, that she actually stopped licking Alex's pussy for a few long seconds. Not that Alex cared. No, her wonderful wife just kept licking pussy, confident that Kara would get back to doing the same. Which to be fair, was a safe bet given their track record.

Sure enough after being overwhelmed for a few long seconds Supergirl went right back to eagerly licking pussy. Perhaps a little too eagerly, given that it ironically caused Alex to stop eating pussy in favour of letting out a long, loud moan into Kara's twat.

Which to be fair was almost just as good as the licks because of the wonderful vibrations that caused, but Kara wanted this to last for as long as possible, so she slowed her role right down to what Alex had been giving her before. In fact, both women settled into the same slow and steady pace, both seemingly contente if this lasted forever, and Kara dearly hoped it would, as she could think of no better way to spend eternity.
