The Same

Summary:

Sarah is a tease and Cosima is just a lesbian.

Notes:

So, I have been rewatching the show lately and can't stop thinking about this two... i know it's kinda weird but you know what they say, don't like it don't read it, i guess?

Unfortunately there isn't a lot of fics about them out there and that makes me extremely sad and I'm well aware i'm not a good writer but hey i'm trying to contribute right?

I'm rewatching S3 right now and really don't remember what happens next so don't take this as extremely canon compliant.

I really wish the show would have a resurgence so we could have new weird lesbians writing about them, but this will probably never happen so all you get is me, sorry lol Anyway, enjoy and leave a comment, maybe I can write more? Who knows

Work Text:

Sarah opens the door with a loud noise and only when she steps inside the small messy flat she notices Cosima's far asleep in Felix's bed. "Shite", she thinks for herself hoping she hasn't woken her up.

She strips only to her panties and bra eager to just lay down and finally get some rest after a really long day but not before checking on Cosima's state. She climbs up the small steps quietly and is relieved to see Cos is still out to this world, she sighs in relief and leans in to give her a kiss on the forehead right after checking her temperature. She still looks a little sick but far better than she was days ago.

(Un)fortunately for both of them Cosima wakes up with the kiss, she turns her head and opens her eyes to the sight of an half naked Sarah, she checks her up and down and thinks this must be a dream. She says nothing.

"Ei, sleepyhead", Sarah breaks the silence. Cosima then realizes this is in fact real and suddenly feels like her body is on fire. "Hey!", she stutters.

"Sorry to wake you up... I was just, you know, checking." Sarah says while she walks around to set herself comfortable on the other side of the bed.

She settles in under the blankets and Cosima turns to look at her. "Nah, it's ok and I'm fine thank you."

There's something in Cosima's smile that infatuates Sarah so much, maybe it's the way her little fangs jumps out every time or maybe it's her shiny eyes. She can't figure out what. "I can't do this without you Cos.", and then she's hugging Cosima closely and tugging the hem of her shirt.

"You won't have to." Cosima looks closely into her eyes,"I promise.", she scratches Sarah's arm in reassurance and smiles lightly at her.

When Cosima has finally decided to go back to sleep she feels Sarah's hand tugging up the hem of her shirt and playing with her belly button, and then she feels hot again, but now is a hundred times worse and she's not sure what is happening or as to why Sarah is doing this but she's fighting so hard against it, oh god please let me be normal, but there is nothing normal about this situation.

"We really are the same heh?", she hears Sarah's voice suddenly and still doesn't get it, "What?", she says trying not to sound so flustered.

"I mean physically,", Sarah explains, "My belly button has this funny entrance too."

"Oh! Right! I never really noticed." Cosima's just trying to sound as normal as possible about this. This is normal, this is completely normal.

"What, you don't touch yourself?"

This is not normal, not normal at ALL!

"Sarah!" She exclaims and it comes out louder than she planned.

Sarah is half smirking half laughing and Cosima's sure she's fucking with her. "Don't be a child Cos, it's completely normal."

"Here", Sarah raises her hand expecting Cosima to touch it much like Cosima herself did a while ago. She does it, what's the big deal about this?

"Feel it." Sarah says it while intertwining their fingers, "See? Even our wrinkles are the same. Kinda cute when you think about it heh?"

But Cosima is not listening, she's hypnotized by the way their hands touch and before she can even notice she's slowly sliding her hand up Sarah's arm, then her forearm, then her shoulder, then her neck.

"Cos?", she doesn't listen. She's just staring at where her own hand is touching with parted lips. She slides down again to try and touch Sarah's breasts but they are covered with a bra and that brings her back to reality.

She blinks twice and is about to say sorry when she notices that Sarah has now her up body completely naked. Cosima is in shock.

"What? I thought you want to see." Sarah teases and Cosima thinks this is not ok but to hell with it, she touches it and squeezes it, and notices how Sarah reacts to her, and it's hot, and she feels her entire body burning up and she doesn't even care if this is wrong anymore she must have it.

Cosima is barely doing anything but touch and Sarah is already whining, "Wanna suck on them?" she asks suddenly and Cosima doesn't even answer it or think about it she just does it.

"Damn Cos, go easy", Sarah grits her teeth but Cosima again is not listening, she's licking, and playing, and sucking and bitting her nipples and Sarah doesn't even know how she's being able to form a train of thought.

"Alright, alright", she manages to change their positions and is now straddling Cosima.

"What?", Cosima asks confused, "was I being too rough?", and to that Sarah genuinely smiles cause yeah she kinda was but she just says: "no, love, I just want you to also take your clothes off yeah?"

For some reason Cosima can't move and maybe is because now just now her brain is starting to conceive what's happening, but Sarah wastes no time and quickly removes Cosima's shirt herself.

"Damn, Felix was right.", she says when she finally takes a closer look at Cosima's breasts, she plays with them and can't get over how soft they feel. Cosima has no reaction, well she does when Sarah puts one of her nipples in her mouth. Has Sarah ever done this before? She asks herself surprised with how good she is.

Cosima is now making weird noses which satisfies Sarah a lot. "Sarah?", she groans once, "Sarah!" she groans twice, "Sarah, wait!", she utters louder this time and Sarah stops almost immediately and sits on her lap, "Yeah, Cos?". She has a look that says "I'm ready to devour you right now" but also seems lowkey upset that she made her stop.

"I don't think we should be doing this.", which is a funny statement cause she can feel her moisture increasing with every second.

Sarah makes small movements on top of her and she's 100% sure she's doing it on purpose. She leans in closer and whispers in her ear. "Why not?"

Her breath is hot and Cosima is so turned on right now she can't even come up with excuses, she says nothing and then Sarah smirks and starts kissing her neck. "It's okay Cosima, nothing wrong with touching yourself." She smiles through the kiss.

Cosima feels like exploding and Sarah's hand is slowing going down on her body, she's kissing, and bitting and licking her neck relentless, she then feels one of Sarah's fingers brushing into her clit under her panties and honestly she's so wet that the only reason why she's kinda feeling it it's cause of the warmth Sarah naturally emanates.

She can't help the moan that escapes her lips, "That's so disgusting," Sarah says while playing with her entrances, "you're gonna ruin Felix bed." She kisses her lips and the way her tongue enters into her mouth is so evasive but she doesn't mind, "Let me help you clean it." She wants more, she wants Sarah to ravish her.

She's not even ashamed to admit that, she feels nastier than ever and that's gotta be Sarah's effect on her, she doesn't understand why though, maybe she can find a scientific answer to this later.

Sarah halts the kissing and when Cosima opens her eyes she's fast between her legs removing her panties, she feels like this sight alone will finish her but Sarah takes too long just staring at her, studying her pray. "I don't want you to hold back, yeah?", and it's all the warning she gets before Sarah finally dives in into her.

It's too much and yeah there is a lot of reasons why she holds back, 1. she doesn't want to be over 2. she still feels a little weird with this whole situation even though she doesn't really care anymore, if that makes any sense.

Sarah carefully puts one finger inside and then looks up to check if it's all good with her lover, with a green light she gently adds another one and notices how much this drives Cosima insane. She thinks about adding a third one but concludes it would be too much since she doesn't know how much Cosima can take it.

She can feel Cosima squirming around her fingers and the little shy noises she's making it's kinda taking her over the edge too but it's still not enough. "Let it go Cos, no one is coming.", she tries to assure but of course she couldn't lose the opportunity to be extra funny. "Well, except for you in a few moments."

Cosima actually laughs at that, between moans of course and she lets it out a muffed scream when Sarah starts playing with her clit using her tongue again. Sarah nips at her and it's probably a warning and just now Cosima realizes Sarah actually wants to hear her, but she has never been much of a louder one.

Well, maybe she can be? This one time? For Sarah? She thinks about all her others encounters and well she was usually on the other end of things... maybe that's why she has never allowed herself to lose it a little more?

Yeah, she still doesn't want it to be over but she also can't hold it any longer, not with how Sarah is doing her. It's not just the way she touches and licks and fucks her, it's her, it's Sarah.

Everytime she looks down and Sarah is looking back at her while she fucks her with her tongue she lets out a loud moan, and Sarah is very well pleased since that's exactly what she wants and that's precisely why she doesn't stop the eye contact during the whole act.

She tries to tell Sarah to stop looking at her like that but all that comes out of her mouth is "Sarah, mm, nng, ple" and Sarah does nothing but smirk.

When she's finally done she lets out such a loud moan Sarah has to quickly cover her mouth with one of her hands while staring at her with disbelief.

"Jesus, Cos, I know I asked you to not hold back, but I didn't know you could be that loud."

Cosima of course is totally spent and she tries to apologize but is unable to, Sarah gets it and just kisses her forehead in response.

Both of them immediately thinks about how funny it is that this is how started.

"It's ok. Fee's neighbors gonna be confused but who cares about what some homophobes has to think."
