Supergirl omegaverse fanfiction

I had to write this because no Supergirl omegaverse fanfictions exist already to my knowledge and that is a tragedy. This will certainly contain F/F pairing(s) and if the story ends up continuing probably other queer pairings idk yet tbh . Also it's certainly gonna be rated M , so like you have been warned .

Also please be forgiving this is my first fic in years and my first omegaverse fic ever . Btw the main pairing will be Kara and lena but these first couple chapters will probably focus on Alex and Maggie (I have my reasons I promise )

As Kara lands on Alex's balcony with beer and pot stickers in hand she called Alex's name to notify her sister of her arrival . "Alex where are you ?!" She called after a second . Then she heard it at the exact same time she could smell what was going on . "Uugh Kara , I'm sorry I'm not sure I'm up for Netflix and dinner anymore!" then she let out an audible painful moan . When Kara smelt the scent of her Omega sisters heat she knew this one must be bad , Alex's sent was far stronger and more desperate/needy than Kara ever remembers her sister heat being before . Kara wasn't sure why this heat was worse for her sister , but that wasn't much of a surprise to her , Kara never really understood any of the human alpha/omega experience , they didn't have to deal with any of this on Krypton . Although she didn't understand she was still sympathetic to her sister because she had seen over their whole life how painful Alex's heats could be and how tedious avoiding all the alphas that would lose control if they got too good of a whiff of her . Kara had previously fought off more horny alphas than she could remember as they grew up .

After a moment Kara dropped the food and beer inside and she rushed to her sister who was curled up in a ball on her bed in the extreme pain and need of her heat . "Fuck Kara it's bad ahhh"she screamed then whimpered . Before Alex could realize Kara had left the room Kara returned with a heat pack , a wet washcloth and a pain reliever for her sister .

"Hey Alex it will be ok , I'm here for you sis , how can I help " as she placed the washcloth on Alex's forehead and the heat pack by her core .

"Uugh thanks sis , you are the best ...Ugh " Alex whimpered again and curled up into an impossibly tighter ball .

"Jesus Alex what the hell is going on , it's never been this bad before " Kara questioned at the same second that it clicked " have you

... "been with" Maggie since your last heat?"

"Fuck that's it , no …. We haven't had sex yet but she has been sleeping here occasionally , I thought it was my mind playing tricks on me but this bed is actually saturated with the scent of alpha …. And one I love at that. Ahhhh fuck I need her , there's no way I can go through a whole week like this , I just can't . Damn that bitch for doing this to me , I can't believe her alpha sent is still that strong just from what's in the bed ."

"Alex it will be ok , do you want me to get her for you , maybe she would be better able to help you when you are like this than I am ." Kara said knowing that not being an alpha she couldn't really help Alex at all .

"Yes , please I need her , tell her what is going on and ask her if she is ok with helping … and tell her I'm sorry , this isn't how I wanted our first time to be but fuck I need it " Alex said and then began whimpering at the thought of her girlfriend , the thought of being taken , of being fucked … knotted , a moan escaped her at the last thought .

"Ok , I will be back as soon as possible " she bent over and hugged her sister "it will be ok "

Seconds later Kara was in the air halfway to Maggie's place.

Karra bursts into Maggie's place "Maggie are you home ? Umm Alex .. she - "Kara gets cut off by Maggie turning a corner into the main room where Supergirl was standing "fuck Kara why do you smell so good !? " Maggie took another sniff " oh god Alex , if she smells that good she must be in a lot of pain " Maggie began to growl as she imagined her girlfriend hunched over in need for her.

Kara wasn't surprised by how much her sisters sent affected Maggie but that doesn't mean she felt comfortable with the bulge forming in-between her sisters girlfriends pants "woah ! keep it in your pants girl ! And yeah she is .. she is really hurting , and she says her bed reeks of your alpha sent , it's not helping at all . She wanted me to ask if you would be willing to help and to apologize for her cause this isn't how she wanted your first time to be , but Maggie she really needs you " Kara explained as quickly as she could . The whole time Maggie gave a low growl that screamed need louder and louder as Kara told her of Alex's pained and needy state

" Yes ,yes yes ! Where is she , take me to her and I will help her for sure " a sick devilish smile formed on Maggie's face as she thought of filling her girlfriend , Making her scream in pleasure .

"I can fly you there if you promise to keep it in your pants " Kara blushed and pointed at Maggie's crotch where the bulge had only grown

"Yes please , now , I want to help her and relieve her pain " Maggie's smile grew even more wicked

Kara still didn't understand these humans but she knew her sister needed this and if she could help she wanted to . She quickly rushed Maggie back to Alex's place and got the hell out of there because she didn't really wanna witness what she was sure was about to happen . As she took to the sky Supergirl considered how the night was still young and just because her plans with Alex had been interrupted didn't mean that she had to spend her night alone . She considered who to attempt to hang with tonight and after a moment she had decided and she changed direction and flew off as fast as she could .
