Work Text:
Felix probably should have been jealous. Most people in her situation would have been. Realizing her boyfriend had feelings for his best friend? And that she liked him back? That would be the nail in the coffin for almost any relationship. But being jealous of Jisung's obvious feelings for Minho (and Minho’s slightly less obvious but still apparent feelings for Jisung) just never occurred to her.
If it had been a different boyfriend and some other best friend, she likely would have been jealous. She probably would have ended things and never looked back. But being jealous of how Jisung felt for Minho was nearly impossible when she could understand it completely from the moment she met her.
Minho- almost painfully cool yet weird and funny, standoff-ish but actually warm, stunning yet... no, there was no but there, she was just gorgeous. Jisung's feelings for her had intrigued Felix more than anything, and by the time she realized that Minho had feelings for Jisung as well, Felix had developed a sizable crush on Minho, who she was pretty sure liked her too.
The solution to that tangled web was almost comically simple. Though that didn't mean that convincing Jisung was.
Once she had gotten past his denials (because who in their right mind was going to admit to their girlfriend to having feelings for someone else?), he refused to believe that Minho could possibly return his feelings.
He wasn't, as he kept pointing out, a famous actor that Minho thought was handsome whom she would theoretically date. Minho dates women, Felix. She has never had feelings for a guy in real life. Trust me. She might like you, but she does not like me.
It had taken weeks of persuasion and tangible examples to get him to admit that maybe, maybe, she was onto something. (Also, a crass joke about a blowjob she'd made in front of both of them while quite drunk. Not her most subtle moment, but her point was proven.)
Finally, Jisung had given her the go-ahead to talk to Minho and see if she was interested in a relationship with them. He still wasn't completely convinced that Felix hadn't lost her mind (there were times when she was citing proof of Minho's feelings for Jisung, her boyfriend, when she wondered if she had lost it), so she was under strict instruction to tell Minho she had acted alone if she reacted poorly. Which Felix really, really didn't believe she would.
So the following day, while Jisung stayed at her place, Felix would go to talk to Minho at the apartment she shared with Jisung.
It was nerve-wracking because, no matter how sure she was of Minho’s feelings for both of them, it was a risk. It was probably insane and possibly stupid. But she knew she needed to try, for all of them. Because if it worked? That would be beyond her wildest dreams.
"Maybe we should wait," Jisung suggested, visibly anxious as he laid on Felix’s bed- hair fanned out against the pillows and the warm light of her bedside lamp highlighting the planes of his face on one side and bathing the rest in soft shadow. "Is there some way we can be extra sure before you say anything?"
"I am sure," she promised, tamping down the nerves she felt as well because letting Jisung see she was worried too was only going to have him spiraling. "It's better to do it sooner rather than later. She has no idea we'd be open to this. I feel like I'm sitting on this massive secret whenever we're with her."
Right then, she was sitting on Jisung's pelvis- folded legs bracketing his hips and weight shifting in his lap as she gesticulated.
"I know, me too," he sighed, reaching up to rest his hands against the dip of Felix's waist. "It's just scary."
"And worth it," she reminded him, putting on a brave front for them both.
"And what if she really only does like you? And wants to only be with you and the two of you run off into the sunset without me?" he fretted, not for the first time.
"Jisung," Felix laughed, half in exasperation. "Listen to yourself. If Minho thought, for one second, that I was propositioning her and I was planning to leave you, she would tell me to fuck myself. It doesn't matter if she likes me or not. She would never do that to you."
Jisung let out a breath, the panicked look in his eyes subsiding. "You're right," he acquiesced on a sigh.
"And I wouldn't either, for the record," Felix added, leaning forward so her forearms were braced against his chest and she could rest their foreheads together.
"I know," Jisung murmured, a little cross eyed as he looked at her as well as he could in that position. "I'm sorry. I know, you're right. I'm just panicking."
Felix shook her head, a soft smile stretching across her face as she reached up to cup a palm against the side of Jisung's neck.
"It's going to be fine," she reiterated soothingly, thumb brushing against his jaw. "I will throw myself under the bus if necessary, but I won't need to, okay?"
Jisung nodded, teeth flashing in a little smile before their lips met in a sweet kiss.
It was familiar and comforting- grounding as all the what-if's of tomorrow floated around them.
As she deepened the kiss, parting her lips and clutching at Jisung's nape, Felix wondered if Jisung could use the distraction. She knew she could.
So it was easy to melt into it, need rising between them as they lost themselves a little bit in each other.
If Jisung seemed a little more desperate as he kissed her and pushed his fingers through her hair, Felix knew it was the nervous energy needing a way out. And she knew that he could probably sense her own anticipation buzzing in the rock of her hips against him, feeling him growing hard beneath her.
Getting naked was easy since they were both ready for bed, shirts and underwear discarded off the side of the bed. A condom was procured from the bedside table drawer, and Felix wasted no time sinking down on Jisung's length with a hitched breath and a sigh.
Jisung let out a surprised grunt at how quickly she took him all in, and Felix allowed herself one tiny smirk as she started circling her hips, just grinding down, before she properly lifted up and dropped back down. That got her a moan, and she grinned, thighs flexing as she built up a satisfying rhythm.
It was nice not to have to worry about making noise when they were at her apartment, rather than the one Jisung shared with Minho. There, Minho’s bedroom was close enough that any sounds they let escape could be easily heard if Minho was awake and in her room.
Though, as she rocked in Jisung's lap, the idea of Minho hearing them started to feel less like something she'd want to avoid. And now that she'd thought about it, she couldn't stop.
"Do you ever think about how close Minho is when we're having sex at your place?" she asked before she could even think about keeping the thought to herself. She struggled with that sometimes- not voicing what she was thinking and feeling, especially around those she was closest to.
Jisung's eyes widened as he sucked in an audible breath, a trembling moan slipping between his lips with the exhale.
If he hadn't thought about it before, Felix was quite confident he was thinking about it now- fingers flexing on her hips and breath stuttering in his chest.
"She's close enough that she could hear it if you moaned her name," Felix marveled as the thought came to her.
"Fuck, Lix," Jisung groaned, brows pinching as he throbbed inside of her, clearly as into the idea as she was.
"Do you think she listens?" Felix wondered out loud, feeling wild with the idea. "Do you think she hears the sounds we try to swallow but can't quite keep in? Has she heard you come? Or me?"
Her thighs were starting to burn as her movements sped up, body clenching around Jisung inside her in a way that was making them both gasp.
Felix's mind was spinning- one thought leading to five others, each hotter than the last. She'd started off just thinking out loud, spurred on by Jisung's reaction. Now though, she was wrecking herself just as much, and she didn't want to stop.
"Maybe she-" Felix cut herself off with a whimper when Jisung reached up to cradle her breast, thumbing against her taut nipple, "maybe she touches herself thinking about you and me having sex- picturing what position we're in and how we move together."
"Baby," Jisung nearly sobbed, pupils blown and lips bitten red. He looked destroyed and it was exactly how Felix felt- every stroke of him inside her fanning the flames as much as her own words were.
"M-my thighs," Felix panted, pace slowing only when her muscles started to refuse to cooperate. "I can't-"
Jisung adjusted his grip on her waist and Felix felt the way his legs bent so he could brace his feet flat against the mattress. She nearly slumped against his chest with a cry as he began to thrust up into her as she used her remaining strength just to hold herself up.
She was close, fluttering and spasming around his length as he drove up into her.
"What if she was here, watching us like this?" she managed to get out between panted breaths. "Would you want to show her how you make me come?"
His moan trembled out if his chest as he slammed into her, driving her orgasm from her as she sobbed with it- clenching tight around him and nearly vibrating with the pleasure running through her all the way from the crown of her head to the tips of her toes.
She felt Jisung come seconds later- thrusting up one, two, three times hard with a helpless, shaking moan. His pleasure extended hers, nerves sparking hot with every shift inside her even as he slowed and stilled. But Felix still felt the little jolts of sensation that buzzed through her and coiled tight in her belly.
Her quick breaths and involuntary twitches of her hips gave her away, and Jisung was running a soothing hand up her back as he carefully maneuvered her so he could pull out.
"One sec," he promised, pulling off the condom and tying it off before rolling off the bed to throw it in the trash. When he came back, he gently helped to get Felix settled against the pillows on her back, body clenching around nothing and driving her crazy.
Then he was over her, skin pressed warm against her body, and Felix brought her legs up to bracket his hips on instinct.
Three of Jisung fingers slid easily into her body, and her sigh of relief was quickly overtaken by a moan as he began a steady rhythm meant to bring her to the orgasm she still desperately needed.
The thumb rubbing tight against her clit had Felix whimpering, knees splaying wider and squeezing around Jisung's hips in turn as her peak built and curled in her gut.
"Close, baby?" Jisung asked, low against her ear, and all Felix could manage was a whine, fingers clutched around Jisung's shoulders as she felt her climax rising up, up-
"Wanna show Minho how gorgeous you are when you come?"
The words shocked her into stillness for a split second- body pulled taut and frozen with her orgasm right behind her teeth. She hadn't expected Jisung to-
"Go ahead, come for her," he crooned in her ear, and any control Felix had over her body snapped as she keened, coming so hard she thought she might have blacked out for a second- ears ringing and fingers tingling as her orgasm washed over her in sweeping waves that felt strong enough to knock her over.
Hearing the rush of her pulse and Jisung's words echoing in her mind, Felix’s peak crested again and she gasped- body surging as she sought every last drop of pleasure before she was completely wrung out and melting into the mattress.
Felix couldn't speak as she fought to catch her breath, eyes still closed and limbs splayed against the sheets like limp noodles.
"Fuck," she cursed weakly when she could manage it, cracking an eye open to see Jisung looking just as off-kilter as she felt.
"Yeah..." he agreed, curling into her side like the contact was the only thing keeping him grounded.
He wasn't the only one. Felix thought that perhaps they were both a little more far gone for Minho than she'd realized.
Another moment passed, and Felix focused on the slowing of her heartbeat and the puffs of breath against her jaw. She needed to turn off the lamp on the bedside table and pull up at least the sheet, but moving felt beyond her capabilities at present.
"I really hope you're right," Jisung said softly against her skin, arm wrapped snugly around her ribs.
Felix did too, the alternative something she didn't even want to consider.
"I am," she replied with as much confidence as she could muster. Because she was confident. She really, really believed this would work. It had to.
If it didn't...
No, she couldn't let herself go down that road.
"It'll work out, I promise," she said, pressing a kiss to Jisung's cheek before leaning up to flip the switch on the lamp and plunge the room into darkness.
Jisung hummed, accepting, and held her closer with his face buried in her neck.
Pulling the sheet up with her toes, Felix kept her arm wrapped securely around Jisung's shoulders and relaxed into the pillow. They would probably wake up sweaty and too warm in a couple of hours, but it was worth it for the comfort now.
Felix really, really hoped she was right.
