A Supergirl Fanfic
Long Overdue
As Kara Zor-El, aka Supergirl, hovered over the skyline of National City, she was happy to say that for once, the city was peaceful. No trouble whatsoever.
"This is so nice, it's been too long since I've seen the city like this." Kara said as she relished in the rare peaceful environment.
Suddenly, her super hearing picked up on a familiar voice.
"Kara… I need you." The voice said.
"Wait a minute, who is that?" Kara said. The voice was familiar but she couldn't place it.
"Kara, I need you" the voice said. It was getting louder and more desperate by the second.
"Kara I need you!" The voice was now yelling out her name.
Alex! It was Alex! She was in danger and needed her help!
Kara took off through the air and arrived at Alex's place in no time.
She burst into Alex's room expecting a fight, but nothing could have prepared her for what she actually saw.
She found Alex laying on her bed naked with her legs spread and her fingers in her pussy moaning out her name.
Kara was left speechless as Alex pleasured herself to the thought of her, but beyond that, she found herself bombarded by emotions as she gazed upon Alex's naked body.
Her toned stomach, nice tits, kissable lips, her clearly tight pussy, everything about her made her think things that she knew she shouldn't.
She had had thoughts, dreams about Alex, but she knew they could never be anything more than just that. They were sisters for fuck's sake! Maybe not by blood, but still… Surely they couldn't do any of that stuff right? Right?
Alex was so into it that she didn't even notice Kara coming in.
Her eyes were screwed shut in pleasure as her fingers went in and out of her pussy while she moaned out "Yes Kara, I need you."
Kara stared in disbelief and she had no idea how to react or how to announce her presence.
Alex raised her fingers to her mouth and began to suck on her fingers to lubricate them for the task at hand.
She reinserted her fingers into her nether regions, placed a hand on her breast and resumed her task.
She suddenly opened her eyes and noticed Kara standing right by her bed.
"Oh what the fuck!?" she yelled as she quickly covered herself with her sheets.
"I could ask you the same thing Alex! What the hell!?" Kara yelled in disbelief.
"How long have you been standing there!? Alex said as her face turned red as fire.
"Long enough apparently!' Kara said as her face turned equally crimson.
"Oh my God…" Alex said as embarrassment coursed through her.
"I'm gonna need an explanation Alex" Kara demanded.
"Oh fuck where do I start… Well I guess I should start with something I should have told you a long time ago."
"And what's that?" Kara asked, although she had a feeling she already knew the answer.
Alex took a deep breath before saying "Kara… I'm in love with you. I've been in love with you for a long time and I want you."
Kara's heart skipped a beat at Alex's words but needless to say, she still had her reservations.
"Alex, I…" was all Kara could stammer out.
Might as well go for broke… Alex thought to herself.
She stood up and let the sheets covering her fall down, revealing her naked body to Kara once again.
Kara's face turned an even brighter shade of red as Alex sauntered over to her, fully naked and unshamed at this point.
Alex was now mere inches away from her and she could smell the scent of her perfume and it drove her wild.
Alex ran her hands through her golden hair and down her shoulders making Kara just shiver under her touch.
"I know what you're going to say Kara. You're going to say we're sisters and we shouldn't do this. But we're not sisters by blood. I see the way you look at me and I know you see the way I look at you."
"So why don't we stop beating around the bush and do what we should have done a long time ago? Because it's long overdue."
Alex grabbed Kara by the back of her head and kissed her sister.
Kara's eyes were wide open at Alex's actions. Sure, she'd had dreams about this, but now that it was actually happening? She had no idea what to feel or what to do.
The intoxicating taste of Alex's lips sent Kara into a frenzy. She was falling deeper and deeper into her own desires by the second.
Her eyes closed as she let herself enjoy the sensations Alex was causing her. At this point, it didn't matter to her that they were sisters. They were just two women who loved each other and wanted each other.
Kara began kissing Alex back in a passionate embrace of their tongues.
Seeing that Kara was into it, Alex pulled her closer so that they were chest to chest and placed a hand on her ass, making Kara jump in surprise and moan into the kiss.
Alex might have been going fast but she didn't care. She was going to make the most of this now that she had Kara right where she wanted her. She finally had a chance to release all of her pent-up desires and she'd be damned if she wasted this opportunity to be with her sister.
They made their way to the bed with Kara pinned underneath Alex.
It certainly gave Alex a boost of confidence to have Supergirl, the most powerful woman on the planet, pinned underneath her.
She always assumed Kara would be a bottom and this encounter was just proving her theory right.
Alex kissed down the side of Kara's neck and peppered her neck with loving kisses that made Kara break out into a series of breathy moans.
"Alex, keep doing that." Kara managed to say in between moans.
Alex was all too happy to continue doing what she was doing if it was making Kara happy.
"Just let your big sister take care of you." Alex said in a sultry voice.
Kara melted under Alex's touch as she screwed her eyes shut in pleasure from what Alex was doing to her.
Alex kissed down the rest of Kara's perfect body, canvassing every inch of it with her soft lips. She finally had Kara in her bed and she was going to map out every inch of the paradise that was Kara Danvers.
Alex flipped up her top to reveal her sister's beautiful tits and began to suck and grope her tits.
Kara's sizable chest melded into Alex's skilled hands and mouth. She might have been the Girl of Steel, but all of her feats and epithets didn't matter when Alex was fondling her chest and sending waves of pleasure through her body. She was all too happy to submit to her big sister right now.
Their chests melded together as they met in a not so sisterly embrace. Alex kissed her sister with the feverish passion of a woman who had been waiting to do it for years.
Alex traced a line down Kara's body with her tongue until she reached the object of all her many taboo wet dreams. Kara's soaking wet Kryptonian snatch.
"You ready Kara?" Alex asked.
Kara furiously shook her head yes in response to Alex's query.
"Don't gotta tell me twice." Alex said as she drove her tongue into Kara's pussy and her head disappeared under her skirt.
"Oh fuck!" Kara exclaimed as she felt Alex's tongue probe her pussy.
"Oh my God this is actually happening" Kara said in disbelief as she took heavy controlled breaths in response to her sister's tongue furiously lapping up her pussy like a starving woman in the desert.
Kara felt herself losing it as Alex continued to tongue her down. Alex reached up and groped Kara's gorgeous tits as she tasted the Last Daughter of Krypton like her life depended on it.
"Alex, I'm getting close!" Kara yelled as Alex's oral assault continued.
She couldn't see her face from under her skirt but she had a feeling Alex was looking very satisfied with herself.
Alex doubled down on licking and sucking on Kara's warm center. She intended to make Kara cum her brains and she wouldn't take no for an answer. She was going to fuck the Maiden of Might into a drooling mess.
"Oh fuck Alex I'm cumming!" Kara yelled as the floodgates opened and a scorching orgasm rocked her body.
Alex didn't slow down, in fact she did the exact opposite. She doubled down on eating Kara's pussy even through the orgasm.
"Goddamit Alex! Fuck!" Kara yelled as she felt her legs shake violently and her eyes roll back in her head as her sister's expert tongue triggered things in her that she'd never experienced before.
Alex resurfaced from under Kara's skirt with her face absolutely drenched in Kryptonian juices.
She leaned up and cupped Kara's face as she tenderly kissed her sister and made her taste herself on her lips.
Alex pulled away and Kara took several shaky breaths as she felt the aftermath of that climax rolling through her body.
"Are you okay? I know I really did a number on you." Alex asked with a smirk.
"Yeah… Yeah I'm okay. Just give me a minute… That was…Intense" Kara stammered out as she breathed heavily.
"Whatever you say Kara" Alex said as she kissed Kara's neck as she waited for her to recover.
After a few minutes, Kara said, "I'm good now."
"Music to my ears" Alex said in response.
"Since I did such a good job on you, I think it's only fair that you return the favor. It's your turn to make me feel good." Alex told her.
"I've been dreaming about this for years and now it's finally happening. Get over here Alex."
Alex responded by mounting Kara's gorgeous face and smothering her with her snatch.
With Kara's perfect Kryptonian breath control, suffocating between Alex's juicy thighs wasn't a concern. She could savor the taste of her beautiful sister as long as she wanted to without coming up for air and she intended to do just that.
Alex moaned out in pleasure and began rocking back and forth against Kara's probing tongue.
Kara flicked and raked her tongue against Alex's needy slit in a desperate attempt to please her sister as much as possible.
"Oh fuck…" Alex moaned out as sweat started rolling down her body.
"I know you can do better than that Kara. You don't have to hold back with me. Show me what you can really do."
If that's what you want… Kara thought to herself.
She reached up and gripped Alex's hips, held her in place and began vibrating her tongue across her clit at high speeds.
"OH FUCKING HELL" Alex screamed at the top of her lungs as Kara ravaged her pussy like a woman possessed.
Kara held her in place and bombarded her pussy with furious licks and strokes. Alex had no choice but to take Kara's tongue for all it was worth.
Alex felt herself explode as she suddenly squirted all over the bed under Kara's relentless attack.
Never one to be outdone, Alex leaned down and began eating out Kara in a 69 position even after that explosive orgasm.
Kara gasped at the sudden sensation on her pussy but didn't let it stop her from devouring her sister's delicious snatch for even a second.
The two sisters met in a mutual endeavor to cause the other as much pleasure as possible.
Alex inserted her fingers into Kara's impossibly tight pussy and ate her out at the same time as Kara assumed a tight grip on her firm backside.
Their moans echoed and reverberated into each other's warm centers as they worked away at each other with reckless abandon.
The sounds of sex filled the room as the sisters raced to the finish.
Suddenly Alex pulled away and stood up.
"What are you doing?" Kara asked in confusion.
Alex reached into a drawer and pulled out a very sizable strap-on and held it up for Kara to see.
Kara's eyes went wide at the sight of the massive phallus.
"Not that I doubt I could take that thing, but I don't know how it'd work. You know, Kryptonian and all.
Alex smiled mischievously and pressed a button on the base of the strap-on and it started glowing blue.
"Blue Kryptonite?" Kara asked with a raised eyebrow.
"I told you, I've been wanting to do this for ages so I was prepared if I ever got a chance." Alex said with a smirk and a shrug.
"And now that I do…" Alex said as she shoved the strap-on into Kara's warm and welcoming mouth.
"I'm going to make the most of it" she finished.
Kara's eyes momentarily went cross eyed from the sudden insertion into her mouth before she let her throat relax and enjoy the sensation of her big sister pounding away at her pretty little mouth.
"That's it Kara. Get it nice and slick for the main event. You know where it's going." Alex said as she teased Kara's clit to rile her up in anticipation.
Not having her powers was a new sensation for her but not an unwelcome one for Kara. The feeling of having her throat stretched by her loving older sister was amazing.
For once in their lives, they were on equal footing and it was a nice change of pace.
Alex worked the strap-on in and out of Kara's eager mouth at a feverish tempo. She watched Kara's plump lips move up and down the shaft of the phallus and the sight made Alex's pussy drip onto the bed.
Alex removed the strap-on from Kara's oral hole and prepared to penetrate another one of her holes. She motioned for Kara to lay down on the bed in the prone bone position and she happily obliged.
Alex took her time eating and fingering Kara's already soaked pussy before the main event. Kara moaned in pleasure and anticipation of what Alex was doing to her and what she was about to do to her.
Alex teased her sister's entrance with just the tip of the cock and made her lose her mind in ecstasy.
"Please Alex…Fuck me…I need it" Kara stammered out in a lust fueled haze.
Alex leaned down and nibbled on Kara's earlobe and listened to her breathy moans.
"You want me to fuck you huh? Say it louder then. Beg for it sis." Alex whispered in her ear.
"Alex I'm begging you, put it inside me. I need it now." Kara said.
"Louder" Alex said in a sultry voice.
"ALEX PLEASE FUCK ME" Kara yelled out as the need to be fucked overrode any sense of shame she had. She felt her face turn redder than it ever had before but she didn't care.
"Ask and you shall receive." Alex said as she took the plunge into Kara's tight snatch.
Kara's breath was sucked out of her as her sister's massive cock penetrated her womanly core.
Alex was the only person in the world that she trusted enough to be this vulnerable with and it felt amazing.
Alex gripped Kara's hips and made the bed rock back and forth under her thrusts as Kara moaned and gripped the sheets until her knuckles turned white.
Kara lost her mind as Alex pounded away at her tight hole and took out all of her pent-up frustrations on her body.
Alex kissed down Kara's back and caressed every inch of her gorgeous sister as she slowed her thrusts and penetrated deep inside of her.
Kara cried out in pleasure as Alex explored places inside of her that had never been touched before.
Alex sped up her thrusts once again, caught Kara completely by surprise and made her scream in love and lust.
"Fuck me harder Alex!" Kara screamed as she was pummeled into the mattress.
Alex slapped Kara's ass as she doubled down on fucking her sister like an animal in heat.
She pulled out of Kara's soaked pussy and flipped her onto her back in the missionary position and resumed pounding away at her.
Alex leaned down and worked her tongue into Kara's mouth as they went chest to chest and Alex did her best to wear out Kara's tight snatch.
Even with the blue Kryptonite negating her powers and making her mortal, Kara was still a very fit and athletic woman and the tightness of her pussy reflected that.
Alex pulled away from Kara's soft lips and latched her mouth onto Kara's prominent chest as she continued drilling into her sister.
Alex rearranged Kara's insides as she felt the Last Daughter of Krypton moan and writhe and thrash under her and neither of them had ever felt happier. The two sisters finally indulging in their taboo carnal desires just felt right.
"Goddamit Kara you're so fucking tight. We should have been doing this ages ago" she said as sweat rolled down their sexy bodies.
Kara would have said something but her brain was too fried with pleasure to speak so all she could do was moan and nod in agreement.
Alex pulled Kara up into a cowgirl position so she was riding her cock.
Kara bounced up and down on her sister's phallus with reckless abandon as she leaned down so Alex could suck on her tits.
From this angle, Alex's cock stimulated her core so much that Kara felt her vision go hazy for a few seconds.
Alex kissed her lower abdomen as she firmly gripped her bubbly ass to help her with her relentless motions.
The feeling of being, for all intents and purposes, a mortal woman only increased the pleasure Kara felt as she did this carnal dance with her sister.
Alex's hands on her ass sent electric shocks all throughout her body as she felt waves of pleasure coursing through her.
"Alex I'm about to cum!" Kara exclaimed.
Alex suddenly pulled out and denied Kara her orgasm but before Kara could protest, Alex slammed their lips together in a passionate kiss.
Alex unfastened her strap-on as they kissed and pulled Kara up into a scissioring position and Kara yelped from the sudden change in positions.
Their warm and soaked pussies rubbed and grinded together as the two sisters met in a taboo but extremely pleasurable dance.
Alex shoved her strap-on into Kara's sexy mouth and Kara sucked the juice covered toy in a lust filled haze. She sucked their combined juices off the sizable phallus like her life depended on it.
Alex pulled the strap-on out of her mouth and locked lips with her lover as they groped each other's firm tits. Their tongues danced together and the heat only escalated the faster their warm centers rubbed together. It felt like there was a fire igniting between their loins.
"Alex, I'm getting close again! Let's finish together!" Kara yelled.
"Let's do it!" Alex yelled back.
"I love you Kara."
"I love you too."
Both of them knew the love they had for each other had changed and evolved and they had never been happier. They were finally doing something they should've done years ago.
With a few more pushes, the two sisters and lovers exploded together as a furious joint orgasm rocked through their bodies. Their eyes rolled back in their heads and their legs shook violently as they kissed and reached the apex of this sisterly sexual encounter.
They collapsed in a sweaty heap and wrapped their arms around each other as they basked in the aftermath of their taboo intercourse.
They looked deep into each other's eyes with a loving look shared between them.
Kara was the first to speak.
"We really just did that huh?" Kara asked as she breathed heavily.
"Yeah we did" Alex answered back in an equally breathless voice.
"I don't regret anything" Alex said.
"The only thing I regret is that we didn't do that sooner." Kara said.
"You took the words right out of my mouth." Alex said as she ran her hand through Kara's golden hair and pulled her sister into a loving kiss.
She pulled away and said, "I really do love you Kara, I always have."
"I know Alex because I've always loved too."
"I guess we're going to have to redefine our relationship now huh? No going back to how things were before."
Alex chuckled and said "I guess we will because we're definitely more than just sisters now. But that can wait until the morning. Let's just enjoy each other's company and sleep."
"Don't gotta tell me twice." Kara said as she kissed Alex before they drifted off to sleep in each other's warm embrace.
The End
