Ibarra & Rin Ending

AN: Long ending for chapter 100!!!!! Also this pairing 😵 I apparently love it. It's more than 16 chapters worth of writing. I hope you all love it too, bummer I didn't cover them in the main story. Also, there's a lot of weird mistakes, so try not to be distracted haha I tried to fix them as I saw them (Even came back in 2021 to fix it more)

It hadn't always been you three together. It had started off with only Ibarra.

This was how the story went:

You wiped the condensation from the bathroom mirror and leaned close, applying your mascara in the small window you'd made on the glass. The tiny room was full of steam and the smell of shampoo and soap.

"How can you take a hot shower in this weather?" you said, capping your mascara and leaning in even closer, scrutinizing your face. You'd had a shower a half hour ago and could already feel a thin film of sweat on your back; it was going to be another boiling hot day.

Ibarra made a sleepy noise, turned the water off and slid the curtain back with a metallic zing. He reached for a towel and you glanced his way, letting your eyes wander over his naked body, his skin pink from the hot water. You'd been together four years, and he never failed to make something else stir inside you, something warm and alive—all he had to do was smile and you'd feel it all through your body.

"Morning, baby," he said smiling, wiping the water from his eyes with the towel. He looked sexy with his long black hair dripping onto his wide shoulders, his chin just a little shadowed with dark whiskers you knew he wouldn't bother to shave off.

You turned when he stepped out of the shower and you exchanged a quick kiss. you felt the vague rush of arousal at his naked body and all the familiar details—the intricate black tattoos that covered his neck replacing the necklace of his childhood, the silver curls of his hoop earrings, the deepness of his voice. And his eyes—so bright and expressive and cunning.

"Morning," you said, dragging your eyes from his face. "You'd better hurry—it's almost quarter to."

You left the bathroom, finished dressing and returned five minutes later to find Ibarra brushing his teeth lazily, staring at his reflection as he did, looking for all the world like he was ready to go to bed, not start his day.

"I'm leaving without you if you're not ready in twenty minutes," you said with genuine irritation.

He made some noise around his toothbrush, acknowledgment or argument, and watched you as you took a few minutes to check your hair, arranging the hair that hung around your face.

You looked your body over, smoothed your blue skirt, and turned around to consult the full length mirror on the wall behind you. It had taken forever to pick the right outfit—something professional looking without being boring, and light enough that you stood a chance of getting to work without being soaked with sweat.

Ibarra moved to the sink and you couldn't help watching his body from behind as he bent to rinse his mouth. He'd barely dried off and you could see the beads of water on his skin. You wanted to run your finger across his back, joining them like a dot-to-dot. You wanted to feel the smooth warmth of his skin underneath yours, crawl back in bed and make love instead of going to work.

He straightened, running his hand through his hair carelessly, and saw you looking. He smiled and you felt it inside; a tug of desire that anchored in your belly and pulled like a tide between your legs. Hastily, you returned your attention to your reflection.

He turned, watching you scrutinize your outfit in the mirror. "Do I look...professional?" you asked uncertainly, turning to view yourself from the side, hoping your ass didn't look too big beneath the linen fabric of your skirt. "Can I convince important people?"

"You could convince me," he said, stepping beside you and taking your arm, pulling you away from your reflection. "To do all kinds of things." He brought you close, his hands slipping to your waist. you knew the water from his skin was soaking into your clothes, and were almost annoyed, but his lusty eyes held yours and your annoyance was quenched by excitement. Only a few seconds of contact and you were already growing warm and aroused. He kissed you softly, with an open mouth, his tongue slipping over your lower lip; all animal appetite, no subtlety. "Especially very naughty things," he said in a low voice. you laughed, even though you didn't want to. "Wicked things."

He kissed you again and you felt a tingle in your stomach, felt your body wanting to yield, to let it happen.

He pressed you against the bathroom wall and started hiking up your skirt. If you let him, he'd be inside you in a matter of minutes, pushing hard in that needy way he always had, like he hadn't fucked in years, though it had probably been less than 24 hours since you had. You loved that—even when he caught you off guard. You loved his needy desire; it never failed to get you wet.

But you couldn't be late to work this morning.

Reluctantly, you pushed his hands away. "Ibarra, don't." You turned your head away from his kiss but he just slid his open mouth to your throat and you sighed, despite yourself. You pressed your hands against his bare chest and pushed him hard, but it only made him press against you more. "Come on—I don't have time for this today."

He ran his tongue over your skin, up to your ear, and sucked your earlobe, earring and all, into his lips. "Just a quick one?" he said, bringing his mouth back to yours. you were still pushing against him, but with much less effort. "For good luck?" you moaned as he searched your mouth with his tongue and for a second did nothing as his hands pulled your skirt higher, his hot palms cupping your ass.

"Oh, fucking hell," said a voice from the doorway. "Don't you two ever stop?" Ibarra's older brother Rin stood in the doorway, scowling sleepily. Quickly, you pushed Ibarra's hands away and smoothed your skirt. Ibarra just sighed and stepped back, his cock half erect and pointing comically in his brother's direction. "Jesus, Ibarra what's your problem?" He looked away pointedly, radiating irritation. "Just get out, already."

You felt embarrassed to have been caught, but more than that, you felt bad for Rin. His wife of five years had broken up with him almost a year ago and he'd been miserable ever since. But Ibarra loved giving Rin a hard time and irritating him on purpose—not maliciously, but he couldn't help himself. That was just how Ibarra was, and it drove Rin crazy.

You felt bad for him because he was a good guy. You could tell he was as embarrassed as he was annoyed, and you knew it had to be hard to see his brother and you together when his romantic life had pretty much dried up since the break up.

"Sorry, Rin," you said quietly as you squeezed past him and ran downstairs.

The accessories and shoes you wanted for your meeting were in the downstairs wardrobe, naturally.

Ibarra came down to join you as you were putting on your shoes; he was looking sexy and totally at ease in his casual pants and t-shirt. He patted your backside as he passed behind you in the dressing room.

"I feel bad for Rin," you whispered. "He's so depressed."

"He's not," Ibarra said casually. "He just needs to get laid."

You rolled your eyes, not bothering to look at him. "Sex isn't the solution to everything, Ibarra."

He didn't answer, but you knew he was smiling at you, probably even ogling your ass. You turned your head after a minute and sure enough his eyes were sweeping down your body, a little smirk on his face.

"I wish we could do something for him," you said, ignoring Ibarra's stare. "We could at least be more careful."

This morning wasn't the first time Rin had happened upon you and Ibarra making out. Ibarra was impulsive and if not always horny, he certainly didn't take much persuading to get in the mood. He found it nearly impossible to not touch you when you were near enough, and once he touched you, he had a hard time not moving closer, touching you more, seeing how quickly he could get you turned on and undressed. You had a little more self-control than he did, but once he started kissing you, not much more.

"You could sleep with him," Ibarra said as he mooned over you getting ready. You looked at him sharply, your incredulous reply coming swiftly.

"What did you say?"

"I said you could sleep with him; that would cheer him up."

"Oh shut up, Ibarra," you said laughing.

"I'm serious, YN. He should be over her by now, it's almost been a year. His ego's taken a beating; if he got laid, he wouldn't be so bitchy."

You laughed again, staring at him. "You really think, don't you? Sex would make everything better?"

"Not just sex, YN. Sex with you." His tongue darted out from between his lips to wet them. "If he got laid by you, he'd snap right out of it."

"You're not serious," you said, but you knew he was. "Tell me you're not."

Ibarra leaned a little closer to you, his voice dropping slightly—for effect, you thought, certainly not because he cared if the help heard.

"We could break up, me and you, and you could go to him for comfort, do some hot rebound fucking." you stared at him, in disbelief. "And after you guys are done, we could get back together." He let his mouth stretch in a smile and raised his eyebrows meaningfully. "You know how good make-up sex is."

The thought of sleeping with Rin was in your mind— you'd never thought about it before, but you couldn't deny the appeal of the idea.

"There's something wrong with the way your brain works, Ibarra," you said decidedly.

"Think of how good that would make him feel, YN, to be pursued by a woman again," Ibarra continued, now sounding like he only had his brother's happiness in his mind. "And if that woman is you..." Now he was stroking your ego. "Mmm, I think getting to fuck you—that would be one hell of a boost to his self-esteem."

You continued to stare at him, at the expression on his face that told you he was serious. He leaned a little closer, and dropped his voice a little more so it slithered warmly into your ear.

"Besides, it would be so fucking hot—the two of you together. You fucking Rin..."

"You're serious?" you laughed, but it was a nervous laugh, one that couldn't hide an excitement you suddenly felt. "What—do you want to watch or something?"

He smiled, knowing he had your interest, and nodded slowly.

You weren't about to admit it to him, but the idea was exciting—You'd never thought of being with anyone else but Ibarra, not since you met, but suddenly the idea of being with Rin was very intriguing, but you weren't so sure about having an audience.

"You're such a perv, Ibarra." you weren't able to hide your amusement.

He smiled again and looked at you levelly. "I'm dead serious, YN."

You stared at him for a few seconds as he watched your reaction, a smile frozen on his face. It wasn't really that surprising that the idea turned him on, you realized. Most things turned Ibarra on, and his tastes definitely leaned toward the voyeuristic, but watching you have sex with his brother? Of course you had approved of allowing him to live with you both, if only to prevent loneliness between the brothers, but what if it was for a more nefarious reason?

"You're crazy," you said finally, shaking your head like you were trying to shake the attractive image that had leaped up uninvited, of Rin, shirtless and messy-haired first thing in the morning. "Now move, I have to try to get this bill passed."

He shifted, kissed your cheek as you passed. "Good luck at the meeting, baby." He gave you a big, sincere smile, and made sure his hand made contact with your ass as you slid past him, his smile turning to a smirk as you walked out.

The next two weeks, Ibarra kept bringing it up-- slipping it into conversation and whispering in your ear, as you were having sex. At first he played on your ego, building up his brother's attraction to you, but eventually he became explicit about how much he wanted to see his brother and you together.

You didn't exactly tell him to stop, but you didn't encourage his fantasies when he brought them up either. You kept telling him he was crazy, laughing it off, but now you were noticing Rin in a way you hadn't before. He was Ibarra's older brother by only a year. Physically they were remarkably similar. They had the same sloping shoulders, the same long limbs, and they moved the same—with an easy, loping stride, filling any space they were in with their personalities as much as their bodies. Rin didn't have the same athletic build as his brother. He was more slender, less muscular, but the differences were secondary to the similarities, making him look like a slightly smaller version of them. They had the same deep-set eyes, same jaw and thick hair. And they laughed the same—and laughed often. You found Rin attractive if only because he looked like Ibarra and you found Ibarra irresistible, but you had to admit he was attractive because of the subtle difference between them, things you couldn't even put your finger on or name.

And then there was the way he looked at you.

Ibarra had been right; Rin found you attractive. You had no doubt once you started noticing—his eyes were often too slow to look away when you caught him watching you. It thrilled you to your very center; stirring up an excited curiosity when he was around. You didn't tease him, but Ibarra did—with your body. If Rin was around Ibarra would find some way to draw attention to you, to your body, sometimes flat out remarking you looked sexy in whatever it was you were wearing at the time, asking Rin if he agreed. More than once, he left the bedroom door open while you were having sex, knowing Rin was home and could walk past at any moment.

On the Friday you got the call that the bill passed, you called Ibarra at work, and he said he'd take you out to celebrate after work. He took you to your favorite bar and did his best to get you drunk while he continued to try to convince you sleeping with Rin was the solution to all the world's problems.

Between your elation at having gotten the bill passed and the numerous beers you'd had, you were feeling pretty good—confident, a little reckless—and Ibarra knew it, but he still looked surprised when you finally said you'd do it.

"Let's go," you said, moving to stand, wobbling a little on your heels. "Let's go home right now and I'll fuck his brains out."

For a second Ibarra just gaped, then he grinned like an idiot and you were out of there like a flash.

You hadn't been entirely serious. You'd assumed Ibarra liked the idea of you sleeping with his brother but would stop it before anything actually happened. That he'd get off on the taboo, and that would be enough. So, you played it up on the walk home— telling him how hot it made you to think of him watching you fuck his brother. It was a game and you were playing along, but when you got home it became obvious he'd been serious and was now more determined than ever to see it happen.

He pinned you to the door before you went in, and kissed you with so much passion it hurt. His hands were everywhere, grasping and stroking, finally settling under your skirt to tug at the waistband of your panties. He bent and quickly slipped them down your thighs, making you lose your balance and fall against him. He stripped them off and straightened but didn't push you against the door again to fuck you like you thought he would. Instead, he steadied you and slid your panties into his pocket, grinning, kissed you once more and fumbled with the key to unlock the door.

The house was boiling hot, but you could hear the fan going in the living room. you could hear the TV too, which meant Rin was home. Ibarra led you toward the sound, his fingers gripping your hand tightly, and you found a shirtless Rin sitting in front of the fan, watching TV. He barely reacted when you came in, only lifting his eyes once without saying a word. you noticed there was a small collection of bottles on the floor beside him; you weren't the only ones a little drunk. Ibarra met your eyes meaningfully and led you to the other chair, pulling you onto his lap as he fell into it. You landed with your legs over the arm of the chair, your feet dangling above the floor. You kissed for a few minutes, softly and wetly, and you wondered if Rin was watching, surprised to find how much you hoped it was true. Ibarra's hand moved to your knee and pushed it down so one of your legs fell atop his, your thighs parting. He drew your skirt up and slipped his hand right over your shaved pussy. You gasped against his mouth and for a second was lost in the kiss and light touch of his fingers on your skin before you remembered Rin. Was he watching?

You turned, drawing your mouth from Ibarra's and shivered at the look on Rin's face—his gaze locked on your open thighs and the movement of his brother's fingers. you wondered how much he could see from his vantage point. Did Ibarra's hand block his view or was he watching his brother's finger slip between your swollen labia? You sighed with pleasure at the touch and the thought that he was watching. you closed your eyes and when you opened them again you saw Rin looking at your face. He looked away quickly, but not before we'd both seen the other looking. you sighed again, thrilled far more than you had expected you'd be.

"Mmm baby, you're so wet," Ibarra growled into your ear, his voice low enough you were sure Rin couldn't hear it over the TV and the fan. He slid his finger along the length of your slit, picking up the wetness and spreading it over your skin. "So fucking wet."  He kissed your neck and slid his finger deep inside you without so much as a cursory circle at the entrance. You groaned and squirmed against him. "Did you see?" Ibarra hissed. "He couldn't look away." You groaned again and looked at Rin again. He was staring resolutely at the TV, the muscles in his face and neck tense as if he was trying very hard not to look our direction. "What a naughty tease you are." You could hear the smile in Ibarra's voice. "Showing off your pussy to your brother-in-law like that." He moved his finger slowly, drawing it out and pressing it in again, his breath hot on your ear. "You're so wet, YN. You're so hot for it—aren't you? You've been thinking about getting fucked by him for a while. You know you have. You know you want to him to touch you like this, like I'm touching you right now." He drew his finger out and entered you again, pressing two fingers together and filling you fast. You groaned and arched your back, your eyes glued on Rin. "Do you want him, baby?" Ibarra's breath was a little faster than it had been a moment before. "Do you want Rin to fuck you? Hmm?"

You squirmed and, to your complete surprise, moaned out, "Absolutely."

Rin turned his head quickly, his eyes landing first between your legs where Ibarra was slowly, methodically, and with great restraint filling you again and again with his fingers. When he lifted his eyes, they met yours and drilled right to your center, penetrating you with a spiraling heat.

"Oh fuck, yes," you moaned. You heard Ibarra gasp against your ear and then he pulled his hand away and pushed you up, off his lap and over the arm of the chair where you caught yourself, teetering unsteadily for a second before you got your balance and looked up at Rin.

You walked toward him, moving slowly through a fog of arousal and alcohol, and staring at his bare chest, impulsively lifted your own shirt up and over your head. you heard a stereo intake of breath from Ibarra and Rin on either side of you. You let the shirt fall to the floor and in a few seconds was directly in front of Rin whose eyes were glued to the sight of your bare breasts. The air from the fan cooled your sweaty skin and a shiver ran through you from the excitement of what you were about to do. The look on Rin's face emboldened you—his expression of lust and confusion; you could feel how much power you had at that moment, his full attention on you. You wouldn't have been surprised to hear the crack of discharged electricity when your knee touched Rin's. You felt the thrill all the way through you, feeling dazed as he looked; your head filled with a sudden and overwhelming desire to touch him, to make him want you. You slid your knee against his and reached out to steady yourself, hands on his hot shoulders, as you climbed onto his lap. Your skirt hid the view, but you could feel your wet pussy opening as you straddled him, and the thought of how close to his cock it would be once you settled into his lap made your head swim.
