Work Text:
You knew you were in trouble the moment you locked eyes with your girlfriend across the room of the ED. The way her eyes burned into you had both ice and heat running through your veins, a warning and a promise in those gorgeous blue eyes.
“No, the color really is great.”
You’re snapped back to your conversation with Santos, only cataloging the movement of her hand a moment too late. She catches a few strands of your hair between her fingers before you jerk away, laughing awkwardly. “Thanks, I think so too.”
Cassie is gone when you look back.
Fuck. Fuck. F u c k.
You grimace as you sidestep Santos, missing the mischievous grin on her face as you blanche, your eyes darting around the room, trying to find Cassie again.
“You look like you just shit your pants.” Santos almost quips, a self-satisfied smirk on her face. “Your girlfriend watching?”
“She’s not my girlfriend.” You snap, a little too quickly. Your relationship with Cassie was still under wraps, and you’d thought you’d both been subtle. Although…The fresh hickies sticking out from both of your scrub tops may have given you away earlier in the week.
“Uh huh and-” Her retort is cut off by Dana.
“Major MVA pileup. Look alive, people, this snow is gonna be a killer.”
----------
Finally having a moment to breathe, you lean against the desk Cassie was sat at, wiping your hair from your face. “That was absolutely insane.”
“Mhm.”
You frown, watching the wrinkles at the corner of Cassie’s eyes deepen, her gaze focused on the computer screen in front of her. Her fingers fly over the keys as she finishes her charting, not even bothering to glance up at you.
“Come on, Cass. You can’t tell me the dude with the gear shift stuck in his chest wasn’t the wildest thing you’ve ever seen.” You push, leaning further over the counter. You flash her an adrenaline-fueled grin, still riding the high from saving a patient.
Your grin turns into a grimace as she still doesn’t look up, your heart dropping to your stomach. “What’s wrong?” She still doesn’t look at you, logging out of the system and standing up, grabbing the tablet lying next to the computer.
“Nothing’s wrong.” Her voice is flat, almost cold. Her eyes meet yours briefly, a look in them you can’t quite place. There’s heat, but there’s something more– something you’ve never quite seen before. “I’ve got other patients, and I’m sure you do too. Get back to work.” One more glance from her and she turns, leaving you in the dust as she hurries toward one of the exam rooms.
“What the fuck?” You mutter, frozen to your spot as hurt bubbles up in you. Cassie has never ignored you like this, treated you like you were a nuisance instead of her girlfriend of six months. She’s always been one to check in constantly– a slight brush of her hand against your lower back as you move through the day, a lingering look after a particularly hard case, even a soft brush of her lips when you’re alone in the locker room.
This was different; this was wrong.
You attempt to get through the rest of your shift, constantly looking over your shoulder for the older woman as dread sinks further and further in you.
This couldn’t just be about Santos, could it? It was the only logical explanation for her behavior, however ridiculous it seemed. She couldn’t be mad enough about it to give you this much of a cold shoulder. You’d been spiraling all afternoon and evening, your body buzzing with anxious energy by the time you’re clocking out.
Your phone chimes with a text, pulling it from your scrub pocket as you head toward the locker rooms.
“Come over. You can shower here. We need to talk.”
Anxiety almost makes you choke as you read Cassie’s text, unwanted tears brimming in your eyes. “Okay.” You type back, capturing your lower lip between your teeth before you send another text. “Are we okay?”
“Yeah, baby, we’re okay. I’ll talk to you when you get here.”
Your worry eases immediately, knowing she’d never lie to you– if things weren’t okay, she’d tell you.
The drive to her apartment is short, parking in your usual guest spot as you shoulder your backpack, taking a deep breath to ground yourself. Everything would be fine.
Cassie paced her apartment, her fingers tapping a nervous rhythm against her thigh. She isn’t angry, no, she’s furious– but not at you, never at you– her anger directed at fucking Santos and that stupid little trick she’d pulled today.
Cassie had overheard her gossiping earlier that week with Whitaker, something about asking you out to a bar next weekend. It had started that little flare of white-hot jealousy, able to push it away and move on, reminding herself that you were hers. Touching you was finally the final straw, that small flicker turning into a full blaze.
The soft knock on her front door halts her pacing, and she rushes to the door, not bothering to look through the peephole before flinging it open.
You startle a little before she’s grabbing your wrist, pulling you inside. “Woah-Cass-“
She cuts you off with a desperate kiss, pushing your bag from your shoulder as one hand settles on your hip.
You push on her lightly, breaking your kiss as you blink in confusion at her. There’s a wild look in her eyes, almost like a caged animal, and it worries you, your hands coming up to cup her face. “Cassie, babe, what’s wrong?”
A heavy sigh escapes her under your touch, the soothing motion of your thumb grounding her. “She touched you.”
You let out the breath you’d been holding— so this was about Santos. “Yeah?” You frown a little, not used to this odd behavior from her.
Cassie shakes her head adamantly. “She can touch you the way I can’t.” She makes her point, her hand coming up to flick at your hair. “She plays these stupid little games because she knows she can. She wants to ask you out, you know?” Her voice is a low grumble, like barely contained rage.
Oh. Glee suddenly courses through your veins, the realization that she was jealous lighting you up from the inside. “She does?” You ask innocently, blinking a few times.
Cassie’s eyes harden, her lids lowering as she crowds you back against the door. “Yeah, she does. Such a pity you’re already involved, isn’t it?” Her lips are inches from yours, her eyes scrunched just a little in a searching intensity.
You let out a quiet “oof” when your back hits the door, your eyes widening in surprise and arousal at her slightly rough handling. “Yeah.” You breathe, your hands hovering above her waist before wrapping your fingers around her ribcage. “I-I mean, no. It isn’t a pity.” You correct, watching a smirk curl up the corner of her mouth.
“Which one is it, baby?” Her whole body seems to loosen, pressing closer to you, her thigh finding its way between your legs. “You want me, or her?” Her voice lowers to a teasing rumble, fingers digging into your hips.
“You.” Your voice cracks as you say it, simpering just slightly under her gaze. It seems to please her as she crashes her lips against yours, her body pressing into yours from breasts to hips. You melt under her, giving her exactly what she needs.
When she pulls back, Cassie’s eyes are dark, the blue of her irises merely a ring of black as she walks backward, pulling you with her. “Wanna prove it to me, baby? Be a good girl and show me how much you want me?” Denying her doesn’t even cross your mind as you nod, excitement heating you from the inside out. “Good.” She grins wickedly, the lines around her mouth and eyes deepening as she turns you around, pushing you toward her bedroom.
The bedroom door closes behind you with a soft click, and suddenly the world narrows to just Cassie– her hands, her mouth, her presence consuming every inch of space around you. It almost suffocates you, like a thick fog that slowly suppresses everything but her.
"Strip." It's not a request, the command wrapped in seductive authority. Your hands move immediately to the hem of your scrub top, peeling the fabric away as Cassie settles onto the edge of her bed, watching you with an intensity that makes your skin prickle.
You're hyperaware of every movement– the way her jaw clenches as your sports bra comes off, the way her fingers curl into the comforter when your scrub pants and underwear hit the floor. She's still fully clothed, and somehow that makes it feel even more intimate, more submissive. It sends such a thrill through you that you physically shudder, your lower lip caught between your teeth.
"Come here." Her voice is rough, gravelly in a way that sends heat pooling low in your belly. You obey without hesitation, stepping between her spread thighs as she reaches out, her hands settling on your waist.
"You know what it does to me?" She murmurs, her head falling forward to rest against your stomach. "Seeing her touch you like that. Like she has any right." Her lips press against your skin, soft and deliberate. "Like you're not already claimed."
"I'm yours," you whisper, threading your fingers through her dark hair. "Only yours, Cass."
She pulls back just enough to look up at you, and the vulnerability in her eyes catches you off guard—beneath the possessiveness, the jealousy, there's something raw and needy. "Prove it," she breathes, and then she's pulling you down onto her lap, your thighs bracketing hers as she captures your mouth again.
This kiss is different from the one at the door. It's slower, deeper, almost reverent despite the edge of desperation running through it. Her hands trace the familiar landscape of your back, your ribs, pulling you impossibly closer until there's no space left between you.
"Harrison with Chad tonight?" You ask breathlessly when she breaks away to trail kisses down your neck.
"Mmhm." She nips at your collarbone, soothing the sting with her tongue. "All night, baby. It’s just us."
You arch into her touch as her hands slide lower, cupping your ass and pulling you tighter against her. The friction is exquisite, and you can't help the soft moan that escapes you. Cassie swallows the sound with her mouth, her hands already working to remove her clothes, and you help her, desperate to feel her against you.
She taps your thigh so you can climb off her, a soft whimper of protest leaving you. Cassie rolls her eyes playfully, slipping off the bed to dig through her drawers. “Don’t be a fuckin’ brat. Hands and knees, baby.” She turns around again, the purple strapless strap-on held in her grasp.
Your breath catches in your throat, arousal spiking so intensely it makes your head spin. You've done this before, but the sight of her holding it, the promise of what's coming, never fails to make your pulse quicken.
"You okay?" She asks, her voice dropping into that careful register she uses when she's about to take control like this. It’s a quick check-in, something you’re always grateful for when she wants to use her favorite toy.
"Yeah," you breathe, already moving into position on the bed. Your upper body sinks into the soft comforter, your ass up in the air as you settle onto your knees, your forehead resting on your forearms. The vulnerability of the position sends a thrill through you, your skin already flushed and sensitive.
You hear the soft gasp she lets out as she inserts the toy in herself, the soft sounds of her adjusting it, and then the mattress dips as she kneels behind you. Her hands– those capable, gentle hands that save lives during the day– settle on your hips with a hard grip.
"Look at you," she murmurs, her thumbs tracing slow circles on your skin. "So perfect. So mine. You know that, right? After today, after watching her touch you..." She leans forward, her chest pressing against your back as she speaks directly into your ear. "I need you to remember who you belong to."
"You," you whimper, pushing back slightly against her, feeling the toy slot between your asscheeks. "Only you, Cass. Always you."
"That's right, baby." Her voice is rough with satisfaction, her fingers dipping down between your thighs, finding you already wet. She teases around your folds, spreading your slick as you whimper, lightly biting the flesh of your arm. She avoids your clit, dipping two fingers inside you to slowly stretch you, to prepare you. “God, baby, this pussy is ready for me. Practically sucking my fingers in, huh?”
"Yeah." you gasp as she strokes you, building the tension higher. "Please, Cass, I need-"
"I know, I know." She coos as she withdraws her hand, and you feel the blunt head of the strap-on pressing against your entrance. "Breathe for me, baby. That’s a good girl."
You take a shaky breath, relaxing into the sensation as she pushes inside slowly, giving you time to adjust. The stretch is perfect– that exquisite edge between pleasure and pain that makes your toes curl. She moves with deliberate slowness, letting you feel every inch of her, unable to help the broken moan that tears from your throat.
"That's it," she whispers, her hands gripping your hips as she bottoms out. "Fuck, baby, taking me so well."
She stills as she settles the toy fully inside you, letting you adjust, and you're grateful for it even as you're desperate for her to move. You finally press your hips back into her, glancing over your shoulder with a pleading expression and soft whine.
"Greedy little thing," she murmurs, and then she's moving, pulling back slowly before thrusting forward with more force. The rhythm she sets is deliberate, controlled, each stroke hitting exactly where you need it.
"Oh god, Cass-" you gasp, your hips pushing back to meet her thrusts.
"That's right, baby girl.” She practically growls, grabbing your shoulder as she pulls you back and up against her, her hand wrapping around your throat as her thrusts pick up speed. She doesn’t squeeze your throat, just holds her hand there as a reminder.
You lean into it, tipping your head back as you moan unabashedly. You reach behind you, over your head, to thread your fingers through her hair, grounding yourself as she fucks you harder. Your tits bounce, her free hand reaching to roughly grope at one, pinching and rolling her nipples between her thumb and pointer finger.
Your breath is stolen from your lungs as you choke, pleasure spiking through you as she hurtles you toward your orgasm. “Cass- I’m gonna come.” You whine, feeling her grind against you with every thrust, surely grinding her clit against the textured base of the toy.
“Me too, baby- Little longer.” She pants, putting her full effort into her thrusts as she reaches between your legs to toy with your clit. She can practically feel your walls clenching around the toy– the way your body resists every time she pulls out has the ball settled inside her pressing against her front wall.
Her hand tightens around your throat, the sound of her hips snapping against your ass and short, quick gasps from both of you are the only sounds in the room. Your cry breaks the near-silence, unable to hold your orgasm back any longer as you fly over the edge.
“That’s my girl.” Cassie groans, her fingers slowing against your clit even as she continues to grind into you, chasing her own release. She chokes, burying her face against your neck as her hips stutter, waves of euphoria washing over her when she finally tumbles after you.
Your fingers tighten in her hair, pressing her face closer as her teeth dig into the sensitive spot between your neck and shoulders, tilting your head to the side as you ride your highs together. You know there will likely be a mark there tomorrow, but to hell with it, you wanted everyone to know. Needed it. “Fuck, yes- Cass-” You finally breathe, your bodies collapsing forward on the bed as she grinds against you, still riding through the aftershocks.
She pulls from you after catching her breath, standing on shaky legs as you collapse to the side, watching her pull the toy from herself with a hiss of overstimulation. She grimaces at the mess on it, the tilt of her lips quickly turning salacious as she turns it in her hand. “That’s fuckin’ hot.” She mutters, more to herself, going into the ensuite bathroom, quickly rinsing it off and setting it on the counter to dry, wetting a washcloth with warm water to clean herself up, bringing it out for you.
She settles back on the bed, gently spreading your legs so she can clean you up, wiping away the evidence of your orgasm from your inner thighs. You hum in contentment, stretching your arms over your head as she cares for you.
She seems much more relaxed now, the tension in her body gone and the stress line around her eyes soft. She leans down and kisses your belly when she's done, tossing the rag toward the hamper before crawling up beside you, pulling you into her arms.
“I’m sorry.” You mumble as you curl yourself around her, your thigh coming up to rest over her hip, arm around her waist.
“For what?” She asks, the lines between her brows creasing a little deeper.
You reach up to soothe them away, giving her a soft smile as you’re distracted by the lines on her face. You trace your fingers down her nose to her mouth and chin, leaning up to press your lips to her jaw. “For making you doubt me. For making you think for even a moment that I wanted anyone but you.”
She scoffs, fingers brushing against the back of your hand as she grips your wrist, bringing your palm to her lips to kiss it. “I never doubted you for a moment. I was just jealous because I want to be able to touch you casually. It drives me nuts that I can’t without getting shit about it.”
You blink up at her for a moment, your lips twitching as you try not to laugh. “You know, everyone already knows about us, right? Santos was ribbing me about you being my girlfriend. I’m pretty sure she was trying to make you jealous.”
Cassie groans dramatically, pulling you a little closer as her lips press against your forehead. “Though I can’t say I’m particularly mad about the outcome, tell that little shit that if she touches you again, she’s losing a hand.”
“Yes, ma’am.” You murmur, grinning as you relax into her embrace. You would not be telling her that– especially if it means bringing out this deliciously jealous side of her.
