Enjoy the conclusion. I still don't own Naruto.

How is he still hard? Karin wondered as she saw his cock twitch in her direction. Her brain felt like a pile of mush … a very turned-on pile of mush.

"Wh-what?" she croaked out once her brain synapses finally reached a point of functionality capable of alerting her to the fact that Sasuke was talking.

"I said," he drawled with a slight raise of an eyebrow. "It would seem I'm not yet satisfied." He lifted one hand to gesture lazily at his erection.

Karin managed to utter an "Um," but her eyes didn't move from the rather impressive dick attached to the man she'd desired since the day she met him.

"Perhaps you'd like to help me out," Sasuke commented drily.

"Yeeeeaaaah," Karin said softly, still in a daze after what she'd seen. But her body seemed to respond to his words even if her mind didn't comprehend them, and she began moving toward him.

He watched her with darkened eyes as she knelt down between his legs and stared raptly at his cock for a few moments before lowering her head to give the tip a gentle lick. He exhaled sharply, and, encouraged, she ran her tongue up the underside of his shaft while her hand gripped his balls.

This is rather like my fantasy, he mused briefly, but then all thoughts were wiped from his mind when she wrapped her mouth fully over the head of his cock. "Ah!" he hissed, one hand reaching out to seize her hair and drive his erection further into the warm wetness of her mouth.

Karin couldn't lie … she liked the strong grip of Sasuke's hand tangled in the hair at the back of her neck, and she liked the roughness with which he shoved his dick up into her throat. She felt her pussy pulsing with the need to be filled, and, half-consciously, she moved her unoccupied hand down to rub herself through her dampening shorts. The burning sensation that shot through her groin at her touch made her groan around Sasuke's thick shaft, and his response was to push her head down harder while he thrust his hips up to meet her.

Fingers moving deftly over her clit, Karin felt herself coming close to orgasm. Sasuke seemed to realize this and, unwilling to allow her to get herself off, he jerked her head up and pulled her to a standing position. Without pausing, he rose, pressed his body against hers and grabbed her hips, lifting her up and causing her to lock her legs around his hips. She felt her back slammed forcefully against the wall beside the open door, and she fleetingly wondered if Suigetsu or Juugo might pass by. But when Sasuke rubbed his naked cock against her clothed center, she found herself unable to care that they might be observed.

"Do you like this?" Sasuke growled in a deep voice that sent shivers down her spine and another heated wave through her contracting pussy. He kneaded his fingers into her ass and continued to move against her in a way that had her cursing her shorts. "Do you know how much I want to fuck you right now? God …" he snarled as he bit into her neck and began unbuttoning the garment keeping him from ramming into her.

Unable to form words, Karin merely whimpered at his questions and slipped her fingers through his hair. At his wordless insistence, she lowered her legs to the ground and stepped out of the shorts and panties that he'd slid down her hips and dropped to the floor. In an instant, her legs were wrapped around his hips once again and he'd driven his cock deep into her pussy.

The force of his entrance had knocked her head against the wall, but Sasuke could tell that she didn't mind (if her pleasured shout was any indication), and he certainly didn't care about anything but the feeling of her warmth encasing his shaft. As he pulled out of her only to slam back in, he found himself wondering why he hadn't done this before. He'd always known she was hot for him … he cursed his pride and vowed to fuck her whenever he had a "problem" again.

But then his thoughts (and his breath) were knocked away—her pussy had contracted sharply around him and she let out a scream he was sure would wake their teammates, even if they were on the other side of the base. He willed himself to withstand the commands of her rippling orgasm and continued to plunge into her as her cum splashed against his stomach and thighs.

Karin couldn't believe the intensity with which she had come, nor did she think her over-sensitized pussy could withstand his persistent thrusts. Yet he continued to pick up speed and the throbbing in her center turned from a pleasured-pain into the beginnings of another orgasm. Sasuke's grunts and warm breath blew into her ear, and she swore she could feel him getting impossibly harder.

"Ah, fuck, Karin," he rasped, his deep voice broken by his harsh breathing.

She watched him pull his head back from the juncture of her neck to squeeze his eyes shut in what might have passed for a look of pain. "Fuck!" he shouted, and his movements became erratic as his second orgasm of the night tore through him. The memory of his cum shooting out onto the floor and the realization that it was doing that inside of her sent Karin spinning into her own second orgasm, and she heard his name tumbling from her lips as thought it was uttered by someone else.

His thrusting slowed as his orgasm faded, and Sasuke let his hands slip down from their position on Karin's ass to ghost over her thighs while he slid out of her, their combined juices dripping to the floor.

At that moment, Sasuke's softening cock hanging out of his pants and Karin shakily sinking to the ground, they both realized that the sound they'd mistaken for their pounding heartbeats was actually the footsteps of their two companions, who had in fact been roused by Karin's scream and had come running to find out what had happened.

Suigetsu charged into the room before either sated occupant could move to cover up, and his battle-ready look quickly turned to surprise as he realized onto what he'd just stumbled. As Juugo poked his head around the doorframe to see what had shocked the normally-loquacious Suigetsu into silence, Karin turned beet red and scrambled to throw her shorts over her exposed privates. Sasuke merely gave the two intruders a withering look and pulled his pants up with a sigh and what might have been a mumbled, "So much for privacy …"
