Author Notes:

!WARNING!

be warned things get...hot this chapter. And also, there is foursome/poly: Rin x Obito x Hinata x Kakashi! If that's not your cup of tea then feel free to skip this chapter.

Context:

Set in au of my au where Obito comes home, Rin isn't abducted into Root, and they all (Obito, Rin, Hinata, and Kakashi) live happily in the Hatake compound. And everyone else is alive, that too. Enjoy!

Summary:

In which Rin is done waiting and gets her man...and woman...and...other man? Regardless, she gets it.

Rin is patient. She has to be, being on a team with Obito and Kakashi, who seem to have the single-minded goal of stressing her out.

(Thank the sage for Hinata. At least she has some help corralling her boys.)

But it's been years, each of them grown into their own persons, and Rin is still waiting.

Well, not anymore. She is done sitting on the sidelines waiting for one of them—just one—to muster up the courage and do something about all this—this tension that's been building between them since their teens and driving her insane.

Rin hears the familiar hum of approval from the security seals Hinata inked into the Hatake compound and throws down the medical case file she'd been trying to read for the past hour. She stands up and stalks out of her office.

"Is anybody home—oh, hey, Rin-chan." Obito takes a step back the moment the expression on her face registers. "Uh, I don't know what made you so angry, but whatever it is I promise it was Kakashi, yup, totally his fault." Obito babbles, sweat dripping down his temple as Rin finally reaches him.

"Rin?" Obito squeaks, back hitting the door. Rin takes hold of the front of his jounin vest and pulls harshly. Rin has to hold back a smile at the way he doesn't resist—so trusting, so willing, so hers—and neatly close the gap between them. Obito's eye widen when she touches her nose to his.

"Okay, okay, it was me! I'm sorry for lying and trying to blame Kakashi. I swear I'll wash my—"

"Obito."

He gulps, eyes flickering down to her lips then to her eyes and back down again.

"Y—yeah?"

"Shut up."

"Okay, yeah, I can do th—mmphf!"

Rin smashes their mouths together, teeth knocking into one another, and finally puts an end to this madness.

Rin has never kissed anyone, and she knows Obito hasn't either, so it's a little messy and awkward, what with Obito frozen in shock for most of it, but Rin doesn't think she would want it any other way.

It's only when she swipes her tongue across Obito's closed lips that he reacts and finally—finally—starts moving. Obito surges forward in a burst of excitement, grabbing Rin by the waist, and opens his mouth to enthusiastically greet Rin's tongue with his. They bat around one another for a bit in a battle for dominance. One that Rin wins by taking his tongue and sucking hard once.

Obito groans and staggers. Rin tightens her grip on his vest and pins him to the door with her chest to keep him from falling. She slots her knee in between his legs for good measure and presses.

Obito suddenly pulls away with a 'pop' , a line of drool stretching between them that he stares at before placing his palms flat against her chest to put some space between them. Rin allows it; curious.

"Uh, Rin, m—maybe we should—I think we should stop for now." His one good eye widens. "Not th—that I didn't like it, no, no! You were—it was good! Really good, but, um…" he trails off and turns his head, not able to meet her eyes anymore.

Rin smiles slowly and leans in closer. His fingers twitch against her chest when she brushes her lips against his ear.

"But what?" She purrs and pushes her chest forward. Obito's hands spasm, squeezing her breasts briefly. Rin's eyes flutter at the sensation. Obito shakes and begins to stammer unintelligibly.

"Is it because of—" Rin grabs his wrists in one swift move and pins them above his head, "—this?" she asks, stepping forward and raising her leg to brush at his hardened length.

"Yes, gods yes," Obito chokes, throwing his head back as Rin rubs her thigh more firmly against the hard bulge straining his pants.

Rin takes Obito's earlobe between her teeth and bites lightly. He stutters out a moan and bucks instinctively. Rin smiles and pulls lightly, eliciting another delicious sound out of him. She lets go and presses a soft kiss to his scarred jaw, rubbing him in earnest and loving all the little noises she's drawing from him.

"Are you sure you still want me to stop?"

She will if that's what he wants, but Rin doesn't think he wants that.

Obito inhales shakily. He looks at her, his single eye smoldering with heat and want, his sharingan flickering on before it's swallowed by darkness once more. Rin feels a thrill go through her.

"No."

He too, like her, is done waiting.

Rin takes his lips in hers. This kiss is even messier than the last, Obito panting desperately against her as he rocks into her. Rin lets go of his wrists, hands sliding up to intertwine with his. She sighs against Obito's lips and squeezes her other leg against herself for some relief. Gods, she is so ready, has been for a while now.

Obito shakes his head and pulls back.

"Maybe we should… ah," Obito sighs when Rin begins pressing hot kisses along his neck. "I was…was thinking… mmm, yeah …maybe we should go somewhere else? Somewhere comfier because—" Obito's gaze strays from hers and his eyes go wide. "H—h—hinata!?"

Rin turns around and there is Hinata, flushed head to toe, still dressed in her pajamas.

Ah. Right. Rin forgot she was home, sleeping in on her day off from teaching at the academy.

Obito stammers and splutters, trying and failing to explain what she'd just witnessed. Hinata just turns redder and redder.

What an idiot, Rin thinks fondly. Although, she really has to commend Hinata's timing. She's always been so much better than their boys; forever prompt and punctual.

Rin adjusts her grip on Obito so she's still holding one hand and walks forward.

"Hinata," she says, voice husky with her desire. Hinata goes another shade redder. "Excellent. You're awake."

Rin grabs Hinata's hand in hers and continues walking through the main house. She stops at her room and then shakes her head.

"No, no, that won't do…" she mumbles to herself and starts walking again. There's a master bedroom somewhere in here if Rin remembers correctly, none of them having taken it. All she has to do is find it.

"Ano, Rin," Hinata begins, voice breathy and high, "where are you—what are you doing?"

"I also would like to know." Obito pipes up, sounding like he'd inhaled a while tank of helium.

Rin ignores them. They'll understand soon.

Is it this one—aha! Found it!

Rin makes a happy noise when she opens a door and finds a large king-sized bed sitting innocently in the center of the room.

"I am—" Rin lets go of Hinata and grabs Obito only to throw him on the bed. He lands on his back with a squeak, his hands immediately going to cover his erection before then clamping his legs shut. Rin sits and scoots up on the bed. She looks at Hinata and her expression softens when sees how startled and confused her best friend is.

"I am…" Rin starts again, one hand snaking its way into Obito's lap and holding on tight. She clears her throat. "I am done waiting." She holds out her free hand, palm up, to Hinata. "Aren't you?"

Hinata's gaze flickers between her and Obito; expression still unsure. Rin falters for the first time. Maybe she was wrong? Or maybe the Hyuuga teach their members that such relationships like theirs—like what she hopes and wants for them—are not acceptable; proper?

Obito clears his throat, drawing their attention, and sits up.

"C'mon, Hinata," he offers his own hand to her, "aren't you coming?"

Hinata takes a deep breath and slowly, shyly places her hands in both of theirs. Rin lets out a breath and smiles at her.

"Yes."

"Good," Rin says and tugs sharply, sending Hinata toppling between her and Obito, "becuase someone is definitely going to come today and I would like it to be all of us."

Hinata yelps and curls into an embarrassed little ball.

"Rin!" Obito wails, flopping back onto his back with a huff. "...I knew letting you and Anko hang out was a bad idea…"

Rin laughs and shifts closer to nuzzle at Hinata's cheek. The girl cautiously opens her eyes. Rin doesn't waste any time, pressing her lips to her best friend's for the first time. Hinata's eyes flutter close and she shyly returns the kiss.

Kissing Hinata is different than kissing Obito, who was all eager—if inexperienced but that's totally hot, so no matter—and burning with passion. Hinata is soft and sweet like mochi. If Rin had to liken it to something else, she'd say it is the relief of coming home after so much time—years, so many years—spent yearning for a place to rest.

Rin watches through half-lidded eyes as Obito attaches himself to the other girl's back. He brings their clasped hands up to his mouth to give her knuckles an affectionate kiss. He whispers something sweet in her ear and dips his head to bury his face in the crook of her neck.

Hinata mewls in her mouth and squirms when Obito begins to nibble at the sensitive skin there.

Rin closes her eyes and cups Hinata's face, lips gliding against one another's in a tender embrace.

Rin is done waiting.

And she knows Hinata and Obito are done too.

There's a whimper at the doorway and the clatter of porcelain and metal falling to the floor. Rin shivers at the wall of heat and want that presses against her back. Rin's eyes crack open and she catches a glimpse of Obito gaping red-faced at their newest addition before her eyes slide close at the hot mouth that latches onto her neck and the wandering hands that kneed her thighs before wedging themselves to fit in-between her and Hinata's clasped hands in a tangle of fingers.

Looks like they weren't the only ones tired of waiting.

Rin moans and wiggles when Hinata takes her bottom lip into her mouth and sucks. Kakashi growls and bites down hard, pushing his erection against her bottom and grinding into her.

Rin moans into Hinata's mouth. She feels herself get impossibly wetter and thinks, yup, definitely worth the wait.
