Summary:

All soulmates can feel pain, but if their bond is strong enough, there's more pleasurable things to be shared, too. And by the time Caitlyn and Vi finally fall together, their bond is already stronger than most.

Chapter Text

It was a bit ridiculous that in a house as large and with as many rooms as Kiramman house, Vi and Caitlyn could not find more than a moment to be alone together.

There wasn’t a family member left who hadn’t walked in on them in the short time since they’d been together. It was a bit more understandable at the Last Drop, less so in the streets of Piltover or alleyways of Zaun. Just that morning, their breakfast date had been crashed by both Mylo and Claggor, who had completely missed their blushing and bashful faces, taking over their table to talk about their latest project while Vi and Caitlyn subtly held hands between their chairs.

Now, they were hiding in the far corners of Kiramman house, in a room that Caitlyn swore no one had entered since she’d grown out of piano lessons, after Tobias had accidentally chased them out of the library.

Vi had Caitlyn pressed against the wall, nestled in between two very old and very valuable Ionian landscapes. One of them was hanging at a precarious angle after Caitlyn’s elbow had bumped it in her haste to get her hands on Vi, though neither of them paid it any mind. Their eyes were closed, hands wandering each other’s bodies as Vi pressed her mouth to Caitlhyn’s in a searing kiss.

Caitlyn was pretty sure she was addicted to Vi’s kisses at this point.

The way she pressed her strong hands along Caitlyn’s jaw to hold her in place while she moaned against her lips, “Baby,” and, “Cait,” and then, “Fuck, I need you.”

Ordinarily, the hot, desperate desire in Vi’s voice as those words fell from her lips would be enough to make Caitlyn’s knees weak. But the rush of want that coursed through her then was like nothing she had ever experienced. She pulled back, gasping, suddenly overwhelmed with the depth of feeling coursing over their bond, the warmth in her belly doubling as Vi stared back at her, lips parted in shock.

For a moment, neither of them moved. Then, slowly, Caitlyn raised her hand, carefully bringing it up to brush along Vi’s jaw. She felt the swoop in her own stomach as Vi’s breathing stuttered. Vi’s hands flexed in her hair, and Caitlyn knew from the way her eyes widened that Vi felt the way it made heat erupt beneath her skin.

They had been feeling more and more sensations coming across from each other recently, but this was new.

When Vi leaned in to kiss Caitlyn again, her lips were as soft as they ever were, but there was a new kind of steel behind them now. Briefly, Caitlyn wondered if she should be embarrassed, knowing that Vi could feel exactly how her touch and her smell and her perfect presence was driving Caitlyn wild. But she could feel it, too, how Vi’s heart raced when she trailed her hand up her spine and settled against the broad planes of her shoulders.

Caitlyn almost laughed. This was Vi. Her Vi, her soulmate–there was nothing to be embarrassed about, not when it came to them.

“I love you.”

She felt her skin erupt in goosebumps at the rush of happiness that swept through her, settling in her chest like a cat before a hearth. The want was still there–very much so, as Vi pulled away, her lips kiss-swollen and perfect–but it seemed content to take the back seat for a moment as Vi tilted her head forward, pressing their foreheads together.

“I love you, too.”

The words brushed against Caitlyn’s skin, and she expected them to be followed by Vi’s lips. But when Vi leaned in again, she bypassed Caitlyn’s mouth entirely, peppering kisses across her jaw to nuzzle sweetly into the spot where Caitlyn’s pulse was racing. She grinned when Caitlyn whimpered, opening her mouth to bite down on Caitlyn’s shoulder.

It felt amazing, but Caitlyn wouldn’t be bested. She pushed one leg between Vi’s, feeling the press of it against her own core as Vi gasped, rolling her hips against Caitlyn reflexively.

“Shit,” she groaned, though Caitlyn couldn’t be sure if it was from pleasure, or because she, too, had heard the sound of approaching voices echoing down the hallway.

“Not again,” Caitlyn hissed, her head falling back against the wall in disappointment. She glared up at the ceiling as Vi’s head dropped onto her shoulder, burying her disbelieving laughter in the crook of her neck.

“They have to be doing it on purpose.”

“I don’t think they are,” Caitlyn replied gloomily. “We’re just that unlucky.”

Vi laughed again. Her hands had fallen from Caitlyn’s hair, and were now lightly gripping her biceps. Her thumbs brushed gentle patterns through her sleeve. “It’s terrible to have so many people in our lives who like spending time with us.”

“Terrible,” Caitlyn agreed, already grinning as Vi lifted her head to share a fond smile with her.

The thought of pulling herself away from Vi now was more than Caitlyn could bear, but they were once again out of time. She still couldn’t resist leaning in for one more kiss, murmuring before they parted, “Next time, I’ll make sure we’re not interrupted.”

Vi chuckled, dropping her hands down to tangle her fingers with Caitlyn’s.

“Sounds like a plan to me, Cupcake.”

Somehow, they found the willpower to tear themselves apart, just in time for all four of their siblings, plus Mel and Ekko, to pour into the room.

“There you guys are,” Claggor declared when he caught sight of them, at the same time that Jayce asked, “What are you doing all the way down here?”

It was Mylo who glanced down at their still-entwined hands, and the scant few inches they had managed to put between them, pulling his face back into a teasing grimace. “Sheesh, you two, get a room.”

Vi chuckled nervously, ducking her head, but Caitlyn caught Mel’s eye, and saw her sister-in-law's elegant eyebrows raise in sympathy.

An idea came to her then.

“Mel,” she began casually, giving Vi’s hand a reassuring squeeze when she felt her soulmate’s gaze on her face, “could I have a word?”

Less than an hour later, everything was arranged.

They returned to where their families were gathered in the sitting room with Caitlyn’s head buzzing. Mel slipped over to Jayce’s side like she hadn’t just given Caitlyn the greatest gift she’d ever received, her serene expression giving absolutely nothing away. Caitlyn, meanwhile, almost tripped over her own feet before she sank onto the sofa beside Vi, too busy staring at her soulmate’s increasingly confused face to pay attention to her own limbs.

“Is…everything okay?” Vi asked cautiously.

“Everything’s perfect.” Caitlyn reached over to take Vi’s hand in hers, unable to hold back her grin any longer. “Fantastic, even.”

Then she leaned in, whispering the plan she had just hatched with Mel’s assistance into Vi’s ear. When she pulled back, Vi’s eyes were wide, but Caitlyn’s fingertips were prickling with her nervous excitement.

“Oh,” Vi finally said, her voice tiny, blue-grey eyes turning sterling as they stared up at Caitlyn, “oh.”

Caitlyn couldn’t stop thinking about it for the rest of the evening. Considering they were having dinner with their families, she had to force herself not to look in Vi’s direction, sure that her face was as hot as the desire still burning beneath her skin. By the time the meal was over, she was almost relieved to see Vi out for the night, if only so she could catch her breath, adjust to the new sensations coursing through her body in the peace and quiet of her bedroom.

That only lasted until she finally dragged her eyes up to Vi’s face.

She wasn’t even aware of making the decision to pull her in until she’d already done it, pressing her lips against Vi’s in a chaste kiss goodnight that still made their siblings make faux gagging noises.

“Goodnight,” she said quietly, squeezing Vi’s hand as she took a careful step backwards.

Things did not get better once she was alone. Caitlyn was laying flat on her back in the middle of her bed, but her heart was beating as hard as if she’d just been running a marathon. She felt restless, and desperate, knowing that the person she wanted to be beside more than anything was already miles away.

She knew what the next best thing would be. Her fingers drifted almost unconsciously over her midriff, but she stopped herself before they could go any lower.

It wasn’t that she couldn’t do that. She just…hadn’t, not since before she and Vi had finally allowed themselves to be together. She knew that Vi hadn’t either. They hadn’t talked about it, though, not since they were kids, hormonal and inquisitive about their own bodies, but also mortified at the thought of the other knowing about it. It was one of the awkward sides of being soulmates, that they were forced to share this intimate knowledge of each other no matter the status of their romantic lives. They had put strict ground rules in place then, ones that both Vi and Caitlyn had followed all these years.

Now, though…things had changed. Their relationship had changed, and Caitlyn had lost count of how many nights she’d stared up at the ceiling these last few weeks, breathless and frustrated with want but unable to cross that line.

She was terrified of making Vi uncomfortable, of ruining this fragile, perfect thing between them.

Her heart must have been racing hard enough to be felt clear across the bridge, because suddenly, she felt the gentle scratch of a fingernail along her hip bone.

Caitlyn smiled, all of the pent up frustration of the night banking for a moment at the sweet gesture from her soulmate. She rolled onto her back to return the touch with one of her own. Not every touch transferred over the soulmate bond–that would be enough to drive anyone insane–but Caitlyn knew exactly which ones would. Scratches were easy, like Vi was doing now, but with a wicked grin, Caitlyn dug her own fingers into the space beneath her ribs, where she knew Vi was ticklish.

She laughed at the sensation of invisible fingers flicking her shoulder, apologized by dragging her own nails gently over the same spot. She knew she was forgiven when she felt Vi’s fingertips wrap around her waist, squeezing it gently.

She figured that would be it, and prepared herself to face another restless night, when she felt another tap against her skin. This one was higher, just to the left of the mole that sat above her hip. A second scratch traced a circle against her thigh, slow and steady.

Caitlyn’s breath hitched.

Slowly, Vi’s touch traveled upward. She explored her own body, and by extension, Caitlyn’s, slowly and carefully. It was a strange sensation, being so purposefully touched like this by invisible hands, but when Caitlyn closed her eyes, she could imagine Vi really was there. She pictured Vi’s strong hands, how they could be so gentle with her like they were now. It was doing nothing for the wave of lust that still threatened to overwhelm her, but it felt too good to care. An answering heat came through their bond, and it relaxed her even as she felt herself coiling in anticipation, knowing that as far apart as they were, she and Vi still wanted the same thing.

Caitlyn couldn’t resist sliding her own hand up to cup her breast, imagining that it filled her palm differently, smaller but firmer, surrounded by wide, strong shoulders. Vi’s hand disappeared from her skin, and Caitlyn had a split second to worry that she’d gone too far before it reappeared, tracing along the flare of Caitlyn’s hipbone once again.

This time, it kept going, lower, and deeper. Caitlyn’s breath hitched again as Vi’s finger brushed beneath the fabric of her underwear, the touch so soft she could barely even feel it anymore.

She felt frozen in place, shocked and thrilled by this development. Luckily, no such spell had been cast on Vi. Caitlyn gasped, squeezing her own breast reflexively as the sensation between her legs changed. She could no longer feel the gentle scratch of Vi’s touch. It had been replaced by an even gentler pressure, moving in tentative circles against her clit that sent sparks rocketing up Caitlyn’s spine.

Her hands flew down to the sheets, and she held onto them for dear life, sure that she was about to explode from the sheer pleasure of finally feeling Vi’s fingers against her.

Logically, she knew that wasn’t what was really happening, that what she felt was just the echo of what Vi was doing to herself. But that was what it felt like, Vi’s own pleasure coiling around hers and heightening it, somehow, making her writhe against the mattress, desperate for more.

Some small part of her thought that she should reciprocate, but she was too afraid to move, too afraid that she had misread whatever was happening and that Vi would stop, shocked or embarrassed to be caught out like this. She clawed at her sheets, widening her legs as if she could give Vi better access to her own cunt.

Her chest rose and fell with heavy, frantic breathing.

She felt the ghost of Vi’s fingers begin to slow, then still, as if she had taken Caitlyn’s stillness as a rebuff, that it was Caitlyn who might not want this. It was that thought that finally pushed Caitlyn over the edge. She plunged her fingers into her sleep shorts, two fingers sliding over her folds with a needy gasp.

She wondered if she was imagining the rumble of a moan in her throat, but she didn’t think so. She could picture Vi’s face as she did it, the way her cheeks would flush as she pressed her hand against her mouth, burying the sound before someone could hear it. She threw her own head back and moaned for the both of them when Vi pressed down harder, her fingers moving quicker now, matching Caitlyn’s pace.

Caitlyn gasped. She had never been this wet in her life. Her fingers were dripping with it, making lewd noises with every pass, but she couldn’t stop.

It was too much.

It was perfect.

If she could open her eyes, Caitlyn was sure they would be crossed with pleasure. She kept them screwed shut, dropping her mouth open instead with heavy pants as she felt her orgasm approaching. Vi’s rhythm had stuttered, grown harsher, and Caitlyn knew that she was close, too. She had felt these waves of pleasure echo over their bond before, but never like this, never tied to her own frantic need.

“Violet,” she cried out, wishing that Vi was beside her, that it really was her fingers making Caitlyn’s toes curl and her back arch against the mattress.

It didn’t matter, though, because she could feel Vi’s pulse thrumming and her heart racing and her pleasure rocketing higher and higher. She pressed her own fingers harder against her clit, the way Vi seemed to like, wanting to be the one to push her over that ledge.

A moment later, she threw her head back with a wail as she felt Vi shatter, bolts of pleasure pushing her hips up into her own grip until she fell, too.

Caitlyn’s mouth hung open with a silent scream. Her orgasm crested just as the wave of Vi’s began again, pushing them right back into ecstasy without the chance to breathe. She didn’t want to, anyway, not if it took a second of attention away from this moment. Her hand had stopped moving entirely, just pressing against her core as it throbbed, almost painful, desperately delicious. She inhaled raggedly, only for all the air to be pushed right past her lips as another wave made her whimper and thrust up into her own touch, mirrored and amplified by the feelings coming through her bond with Vi.

She felt a tug against her scalp, imagined Vi tangling her fingers in her hair as their orgasms finally began to recede, her body still twitching with aftershocks and her beautiful face open and radiant.

It was almost enough to push Caitlyn over the edge again, if her entire body hadn’t already collapsed against the mattress. She was shaking, chest heaving, as she stared up at the canopy of her bed. She couldn’t quite believe what they had just done, or that they had waited so long to do it.

She didn’t think she would survive the wait before they could do it again, this time in person.

“Shit,” she gasped, covering her burning face with shaking hands, “shit.”

The hotel, Caitlyn was sure, was beautiful.

She didn’t care.

She walked through the lobby without sparing a single glance at any of the decor, recovering herself only long enough to politely greet the desk clerk as she and Vi passed by, heading straight for the elevator. Neither of them had spoken much since meeting outside Kiramman house that morning. Vi hadn’t even pulled Caitlyn in for her usual greeting kiss, though Caitlyn thought that was probably a good thing. She didn’t think she could restrain herself any longer, not after what they’d done last night, and not before what they were about to do now.

The elevator doors closed, and a long moment passed in silence before they realized that it hadn’t yet moved.

“Which floor?” Vi asked sheepishly, hand already raised towards the panel of buttons that they had both entirely forgotten to press.

Caitlyn cleared her throat, the key that Mel had passed to her heavy in her pocket.

“Top floor.”

The button illuminated as it was pressed, and Caitlyn slid the penthouse key into the slot, and the elevator finally rumbled to life. When they glanced at each other again, they couldn’t hold back their slightly embarrassed laughter any longer, both of them instantly relaxing now that they were behind closed doors.

Alone.

Together.

Their laughter died away, and Vi turned to face Caitlyn. They looked at each other for a moment, before Vi closed the distance they had kept between them with one slow, careful step. Caitlyn pressed herself against the elevator wall, reaching out to bring Vi with her with one hand on the lapel of her jacket, tilting her chin up until Vi's lips were a hairsbreadth from hers. She exhaled one last, shaky gasp, her entire body locked in excited anticipation that she could feel mirrored by Vi.

She leaned in, and Vi did, too, all of the pent-up lust pouring out of them both in an unstoppable rush as their mouths crashed together.

Vi pulled Caitlyn’s hand off of her jacket, pinning it to the elevator wall instead as she pushed her tongue past Caitlyn’s lips. Neither stayed there for long, and Caitlyn let her head fall back when Vi kissed her neck instead, her hands moving up to the exposed skin of Caitlyn’s throat. There was no trace of their earlier shyness left, as Vi’s lips returned to Caitlyn’s, moaning against her mouth when Caitlyn’s hands slid up her body.

She kept them moving, up the strong lines of Vi’s stomach, around the swell of her breasts and shoulders. She straightened to her full height, walking them backwards until it was Vi who was pressed against the elevator wall, Vi who was cradled between Caitlyn’s arms, and Vi whose mouth opened to Caitlyn’s gentle tongue.

Her hands explored, too, falling from Caitlyn’s hair down to her stomach, then up, up to cup Caitlyn’s breasts in her palms.

“Fuck,” Caitlyn gasped, because it was better, so much better than it had been last night, with Vi’s touch substantial and real against her.

Distantly, she was aware of the gentle vibrations of the elevator stopping, but it didn’t mean anything to her lust-addled brain. Not until, with a polite ding!, the doors opened, revealing the grandeur of the Medarda suite to Vi’s shocked gaze.

Thank you, Mel, Caitlyn thought hazily, kiss-drunk, as she pulled Vi out of the elevator.
