It’s not just that Lena is pretty.
Lena takes her breath away. She makes her swoon with the way she bites her lip, and god, the first time they kissed – and the second, and the third, and the fourth – Kara couldn’t help but float accidentally.
Lena is… absolutely everything.
And then, there’s Sam.
Sam, with her bravery and her competence and her loyalty and her kindness.
Sam, with her never ending zeal for protecting her child, with her strength in overcoming the forces coursing through her body, because the capacity she has for love is…
Well, Rao, Kara wouldn’t mind experiencing it for herself.
And she would talk to Lena about it – she talks to Lena about everything – but she thinks she may be cheating on her, sort of.
Not physically, of course.
But emotionally.
And she thinks, maybe, that that’s worse.
And she would talk to Alex about it, because Alex listens, and Alex uses the word polyamory and assures her that it’s totally a thing and that she should definitely communicate with Lena about her feelings but that she’s certainly not doing anything wrong.
But then Alex she stammers and blushes and gets overwhelmed by all of Kara’s rapid-fire questions.
Which is why Kara is still waiting on her big sister’s couch when Maggie gets home.
“Maggie, your wife is so useless. I need your help,” she announces from her sprawled state before Maggie even gets her boots off, and normally Alex would come up with some retort to being called useless, but Kara also deployed the “w” word, which still – even though they’ve been married for almost a year now – makes Alex giddy.
“Sure thing, little sunshine sis. What do you need?” she asks as she kisses Alex hello, slightly parted lips and kisses for both eyelids and the tip of her nose.
Maggie plops herself onto the couch, still in her oversized NCPD windbreaker, and Kara immediately stretches out to put her feet in her sister-in-law’s lap.
Alex’s heart warms at the sight.
“I think I might be cheating on Lena,” Kara explains without preamble, and Alex groans as Maggie blinks.
“You’re not, Kar,” Alex tries to tell her again, but Maggie just tilts her head and squints slightly.
“Because?” she asks Kara softly, and Alex’s heart flutters again, because even after all this time, Maggie still has that same complete commitment to listening that she had the night Alex stumbled her way out of the closet.
“Because Lena and I are dating. Obviously. But I think… I think I might like Sam? But not instead of Lena, you know? I love Lena, I love her now more than I ever have – I love her more every day – but I think… I think I have feelings for Sam, too. And I want… Alex, cover your ears – I want to do things with Sam, too, you know? Sexual things. And I know Alex said polyamory is a thing on Earth, and I guess it is, you know, but that doesn’t take away from the fact that I feel like I’m betraying Lena somehow, and she already always feels so rejected by everyone, and I never want to be the cause of her feeling that way, not ever, and – “
“Hey, whoa, slow down, Kara. Breathe, alright. It’s okay. I promise. You’re okay. Lena’s okay. Everyone’s okay. Yeah?”
Kara breathes slowly, steadily, eyes fluttered closed as she lets Maggie hold both her hands in her own.
“Kara, Alex might be useless when you want to start talking specifics – “
“Hey!”
“It’s kinda true, babe. But she’s right. What she said. About polyamory, and that you’re not cheating. You’re not doing anything wrong.”
“But I have to tell Lena?” Kara asks, her voice small and terrified, and her eyes even more so.
Maggie sighs as she tilts her head. “I mean, even people in monogamous relationships – who want to stay monogamous – get crushes on other people, get attracted to other people. That’s alright. It happens. Communication about it can really help, though. Especially since you seem like you might want to explore something with Sam, too? And I gotta say, kid, I don’t think your girlfriend would be opposed to that. She and Sam have a really special bond, and I think it could translate really nicely into something else. If you all wanted, I mean.”
“But… how would it even work? If she wanted to? If Sam wanted to?”
“That’d be up to you three, you know? There are all sorts of ways to make sure this stuff works healthily and everything’s above board and all that. And Alex and I can help talk you through it. What to say, I mean. If you want to practice what you want to tell Lena.”
“Yeah?” Kara asks, leaning up to cuddle into her sister-in-law, and Maggie kisses her temple as she tosses an easy arm around her.
“Absolutely.”
“I’ll order extra pizza,” Alex grins, because it’s going to be a long – and very worth it – night.
