This will not happen again

(A/N: Warning, this chapter contains a lemon. That's all the notice you'll get.)

There were just three months before the chunin exams and her missions continued to increase. Some were more difficult than others and some… let's just say, Oboro had more fun picking her nose than waiting in the shadows to collect information. In all honesty, Oboro hated the spying part of her job. She preferred the short, action-packed missions. Well, at least she had someone to talk to. Kabuto had been forced to come with her on this one.

"Don't glare at me. I didn't make you tag along." She spat as Kabuto gave another growl. "And I certainly didn't want you to come either." Oboro smirked as his glare intensified. They were standing at the docks of a small fishing village, just outside of Kirigakure, waiting on the boat to take them further into Wave country. Their mission was to look in on one of the bases which held a number of test subjects. Apparently, Orochimaru didn't trust her enough to do it alone. 'To hell with him.' She thought as the boat lulled up to the dock.

"I have more important things to do than play babysitter." He growled out as they stepped aboard the dingy vessel.

"Your hands don't count." Came her retort, sauntering over to an open bench. As unexpected as her reply was, all Kabuto could do was stare while following her. But he didn't say a word; it was none of her business who he slept with.

"So says the woman who can't keep a lover." Kabuto finally said with a smirk. Hell, every man she had been with disappeared the next day. Oboro turned her head to look at him.

"You know, in some species of cobra when the female finds the male to be inadequate…" she paused, a small smile lining her lips. "The female will devour the male and look for a new one." Well damn, now she sounded like a praying mantis or black widow instead of the slithering serpent she was.

"So you…" he looked around to the other people on the boat then back to her, lowering his voice. "You killed all five of them?" he asked, suddenly finding it harder to breath.

"They were… unworthy of further attention." In other words; she wasn't satisfied with their performance which left her unsatisfied at the end. Her golden eyes locked on his for a brief moment, braking when the boat jerked and swayed away form the dock. The rest of the journey was spent in silence as the boat pulled to port at a small rice crop village.

Samehada gave a low hum in Kisame's ear. Something big was near. He grinned and turned to his partner.

"Itachi-san, I do believe we have a hit."

"Hn." The younger of the pair replied as he turned to his blue-skinned partner. "How far?"

"Less than a mile south." Kisame grinned wider. He knew his partner well enough to know that Itachi was interested in the turn of events. So far they hadn't see or felt anything out of the ordinary for weeks. Now though, both men weren't going to waist time guessing just which one was nearby. Leader gave explicate instructions to find and capture whichever tailed beast they came across first… and God knows you don't take Leader-sama lightly.

"Inform Leader-sama first, then we will move in." The Uchiha stated while walking farther down the road. They needed a more secluded area to perform the jutsu, being so close to Kirigakure was dangerous.

Believe it or not but the Waterfall village wasn't the only place where you could find such a breath taking site. The water was the color of the sky, such a clear blue you cold see to the bottom of the wading pool. A rainbow glowed benevolently above as if saying nothing could go wrong here, but she knew better. Only time would tell as the horrors of Test Site 13 lay just behind the obvious illusion.

Kabuto lead the way up the rocky cliff trail and behind the waterfall. A cave came into view the closer they got; a crack was more like it. The opening was so small that they had to walk sideways to reach the bolted metal door at the end. Using his chakra, Kabuto opened the door and slid inside. Oboro followed close behind as they stepped into a large cavern. There were six hallways to choose from but he led them to the second on the left.

"The lab is just down the hall." He said over his shoulder while he continued along the corridor. "It won't take long to get the information." She nodded as she walked, looking into the rooms they passed. A number of them had gurneys under a large light. Most of which were stained with blood. A shiver ran the length of her spine.

"What kind of experiments did he perform here?" Oboro questioned, a disgusted tone in her velvety voice. Kabuto stopped walking and turned to face her.

"If it weren't for the lies, none of this would've been necessary." He said with a shrug of his shoulders.

Oboro rolled her eyes. "You didn't answer my question." She gave a huff and crossed her arms.

Kabuto rolled his eyes. "Anatomy. He had to find a way to make the Curse Seal work properly, so, a lot of people were subjected to experimentation." He said as he walked into a room. His fingers tapped the keys of the computer and accessed the necessary files.

"Then why come here if you aren't using it?" she asked as she leaned against the wall. Kabuto turned from the computer and smiled at her. A smile that sent a chill through her body.

"But we are." And to prove his point, Kabuto turned on the lights. The room was lined from floor to ceiling with rows of tubes… with bodies in them. Oboro pushed herself off the wall and walked cautiously over to one of them. What surprised her about them was that they kind of looked like her. The familiar ebony hair, pale skin and purple eye markings making it blatantly obvious that they were trying to make the perfect shell. "You were special, it seems."

"How so?"

"You were the only one to survive… these are basically your clones - sisters - yet you were the first and only survivor." He said while walking to stand behind her. Oboro placed a hand on the tube and cocked her head to the side.

"Why the curse seal? It won't work if they don't have chakra to attach the seal to." Her hand slid down the glass as she watched the lifeless body bob softly from side to side.

"If any of them survived, they would be given a supplement to keep the little chakra they had at a more normal level until they were ready to be used. Thus making the curse seal a viable attachment and insuring their survival until they were needed." Kabuto explained then turned back to the computer. "We can go now, the information has been downloaded." Oboro walked away from the tubes and out the door without a second thought.

Itachi looked over the water in the waiting pool and frowned. Kisame had to be wrong. Said blue-skinned shinobi grunted as Samehada gave a low hum. It was definitely here, but where exactly? The waterfall roared before them but there was nothing else to see.

"You are certain it's here?" the Uchiha questioned in a board tone.

"Of course, Samehada doesn't lie." Kisame responded as he looked around. Just up ahead there was a toe-path that led up to the waterfall but it seemed to stretch and go up and around the falls. "Split up and search?" he suggested but was too late, Itachi was already walking up the path. Snakes erupted from behind the waterfall. There was no warning, no flare of chakra and no time to react to the slithering serpents that made their way to the two-man cell. Itachi and Kisame jumped back, landing atop the water of the wading pool. "That didn't take very long."

"What do you want?" a voice asked, oddly feminine through the roar of the falls. Neither man said a word as Kabuto and a young woman stepped into view.

"Yakushi Kabuto, stand aside." Itachi said as he took a step forward.

Oboro looked between Kabuto and the two shinobi down below. "Friends of yours?" she asked with a smirk.

"Hardly." Kabuto answered as he moved closer to her. He turned his attention back to the two Akatsuki members. "What business do you have here?"

"Hand over the Jinchuuriki and you'll live." Kisame growled while hefting Samehada and readjusting said sword.

"And what makes you think I'm a Jin-whatever-you-call-it?" Oboro sneered as she crossed her arms. "I'm just another soldier."

"Samehada doesn't lie, bitch."

"Did he just say what I think he did?" she asked with her jaw agape and heavy glare in her eyes.

Kabuto reached into his pack and pulled out a scalpel. "Calm down," he whispered to her. "You can't let them see the demon's power."

"You're suggesting I hold back." She said more than asked, her voice just as low as his. Kabuto nodded. "Fine, which one do you want?" she sighed while reaching for a scroll.

Kabuto was smiling mirthfully when he looked at her. "I'll take Itachi." And with that, Kabuto leapt away.

"Thanks for stiffing me with the fish, asshole!" she shouted then ducked, Kisame didn't waste any time getting to her. For the sake of keeping her cover, Oboro let him kick her in the gut. The force of which sent her skidding to a stop on the banks of the small pool. "That was smart." She grunted as she stood.

"I'm surprised I didn't brake you." Kisame sneered with a devilish grin. He sung Samehada wide and crouched all in the same motion. Oboro staggered back, feeling her chakra slip away as the sword just missed her nose. It wasn't a lot but it was enough for her to know not to get too close to him.

'…And with a long range and radius… I have no choice but to get right on top of him.' She thought as Kabuto landed next to her, and not in a good way. Playing her part, Oboro moved away from the two men as Itachi appeared next to Kisame. "Desperate times call for desperate measures." She whispered and tossed her scroll on the water. A quick succession of hand signs later her foot stomped on the scroll and the water began to churn. Once a crystal clear blue color, the water dimmed to an inky black, thick in viscosity. A final flick of the wrist and Oboro made the signs for a Katon jutsu. White, hot fire ignited along the surface of the wading pool causing the Akatsuki members to jump for safe ground while Oboro snatched up Kabuto and beat a hasty retreat.

"I really hate dirty tricks." Kisame rumbled, watching as Oboro ran at a lighting pace away from them.

"It forced us to seek shelter, did it not?" his monotone partner responded. Kisame nodded with a grunt. "Then her plan worked perfectly."

"I'd love to learn that little trick though."

"I already have." Sharingan eyes narrowed in the direction of the retreating party. He turned away from them and walked calmly in the opposite direction. "Kisame, come."

Kabuto had no idea what to think when he woke up some hours later. He was in a tent, that's all he knew. Kabuto looked himself over to find bandages on just about every part of his body and his chakra was working overtime to heal the more serious injuries. He sat up with a grunt, letting the covers pool around his naked torso.

"Lie back down, you haven't healed enough to move too much." Came a voice from the other side of the tent. Oboro sat hunched over in the corner, mask on the ground and hair in her face. When she looked up, Kabuto could see the bags under her eyes. So, he tried his best to lay down without hurting himself as Oboro crawled over to him.

"How long have I been out?" he asked as he noticed that Oboro had left her mask on the floor.

"A few hours, seven tops." She sighed rubbing her eyes with the palms of her hands. "As I'm sure you're aware, you're in a tent. I met up with a group of gypsies… imagine my surprise when a few of them started crying when they saw you." There was a hint of a smile on her lips as she looked over his bandages but the tiredness in her eyes spoke far clearer.

"Ah, yes, I trade with them a lot." Kabuto said while watching her work. "You know, I never imagined you as a medic."

Oboro glanced up at him. "I've watched you enough to get the basics. Besides, you little trick has been working better since I crushed a soldier pill and put it in your water." She pulled the blankets back up to his chest and sat back on her heels. "Do you thing you can hold something down?" Kabuto nodded and she stepped out side of the tent.

While she was out, a few women poked their heads into the tent to see how well he was doing. Kabuto just lay there with his eyes closed as he listened to them whisper back and forth with a giggle here and there. It became apparent to him that the gypsy women believed that he and Oboro were an item. As much as he might want that to be, Orochimaru would have his head if he tried anything with her.

"That's enough ladies." Oboro said as she stopped in front of the tent. "He needs to rest still, leave him be." The women cleared the way and Oboro walked back into the tent. Kabuto opened his eyes and stared upward. "You know, for an evil doctor, you sure do have a lot of fan-girls."

Kabuto scowled. "Don't remind me." He looked at her then. Oboro was smiling an evil smile with her head cocked to the side. "What the hell did you tell them?"

"The truth." She said with a huff. "That we are mission partners and you got your ass handed to you on a silver platter." Oboro stalked over to him and set the tray of food down. He glared daggers at her. "If it makes you feel better… I didn't tell them that I was holding back."

Kabuto jumped then, pouncing on her like a hungry lion. He trapped Oboro under him as the blanket fell away. It was only then that he realized that he was completely naked. His exposed member brushed none too gently against her thigh but Kabuto repressed a shiver. He was too pissed off to care about physical desire.

"If you so much as whisper this to any one… I'll make you pay." He hissed to her, never mind the fact that his hair had been let out of its ponytail and now showered over her face. She smirked at him, playing it cool.

"Make me pay… how?" she beamed up at him, fully enjoying the frustrated glare she was receiving from him. Her arms were pinned at the wrists, torso trapped under his and one of her legs was twisted around his. Aside from the burning heat pooling in her abdomen, Oboro was as cool as a cucumber in their very suggestive position. A grin suddenly formed on Kabuto's lips as he settled a little more of his weight on her pelvis.

"I have my ways." The attraction had always been there, they had just never acted upon it - mostly ignored by both parties. But now - and in such a state - they couldn't ignore it. Kabuto's lips descended to hers, pressing softly to gauge her reaction. Onyx eyes fixed on golden orbs as Oboro pressed back. Her eyes fluttered closed as she tilted her head… and the battle was on. The kiss went from a test to a full blown dominance competition. Oboro flipped them over and straddled his hips, never breaking contact with his mouth as her hands glided over his chest and arms.

"Oboro-dono… Toshiro wishes to speak with you." A voice called from outside the tent. Oboro shot up and flew away from Kabuto as if coming to her senses.

"I'll be right there." She said as if there was nothing wrong. All the while she looked upon Kabuto as if he was the only man on earth and she the last woman. "Maybe another time." She whispered to him as Kabuto snatched the blankets to cover his erect manhood. "Eat up and get some rest. We leave early tomorrow."

~xxx~

It had to have been about three in the morning when Kabuto sat up and got dressed. He had passed out some time ago, waiting for Oboro to return… but the thing was, she hadn't. He stepped out of the tent and found that everyone was asleep, save a couple men sitting by the fire. Kabuto had asked them where she ran off to and they had told him that she went down to the river. And so he went.

Oboro hand just taken off her shirt and pants when Kabuto emerged from the bushes. She stared at him for a good long while as he sat down on a rock.

"And just what do you think you're doing?" she asked with her hands on her hips.

"You know, no one's going to take you seriously when your half naked." He said with a smirk. Oboro's hands flew into the air in exasperation. Figuring that she wouldn't be rid of him any time soon, Oboro reached for the clasp of her bra and unsnapped it with one hand. Kabuto just watched as the dark fabric fell to the ground atop the pile of clothes. And before he know it, Oboro was naked and in the water. She swam around the warm water in the dark while Kabuto just sat there.

"I'm sure if you're well enough to walk around, you can take a dip and get clean." She hollered from the water. Kabuto smirked and began to undress. Moments later he joined her in the deeper end of the river as she floated while waiting for him. She suddenly found herself being grabbed by the arm and spun around in the water.

"You tempt me, woman." He growled then pressed his lips roughly against hers, dragging Oboro closer as the water lapped around them. Oboro responded immediately, arms waving around his neck and legs encasing his middle. Kabuto pulled back a moment later and gazed into her lust filled eyes.

"I do not tempt." She hissed. "I simply push for what I want." This time, she growled and descended upon him. The kiss grew in intensity as Kabuto moved them to shallow waters.

He was not gentle and she was not quiet. The moment Kabuto's feet scraped against the rocky surface of the riverbed he sheathed himself within her. Oboro let out a loud cry of pleasure as his thick member careened into the bundle of nerves deep inside. There was no foreplay, they were not lovers - in the 'love' sense. No. This was strictly a release from the everyday. The wanting, wondering… the need to feel something different. To ignore the desire now would only prove that they were insane.

Oboro's legs tightened around his waist as Kabuto began to thrust faster and harder, the sudden need for release becoming more and more prominent as the time ticked by. Her full breasts pressed firmly against his chest, heaving and gasping as she called his name time and time again. Kabuto's hands grasped her ass in a firm grip while he buried his face in her shoulder, biting the juncture before his nose. By now, she had begun to work with him, hips moving in rhythm to his thrusts. The friction between them was blissful as they moaned and sighed in pleasure. Finally, her walls began to quiver, signaling that she was near. Kabuto doubled his efforts, pounding relentlessly into her flesh as Oboro cried out into the night.

"Ka-Kabuto!!"

"Nngh…" she squeezed him tightly, milking him for everything he had as he emptied himself within her. For a moment, no one spoke as they tried to catch their breath. Kabuto set her down in the water and rested his forehead against her shoulder as Oboro shifted closer to him, arms still around his neck. "Was it good for you?" he asked jokingly.

"I am satisfied." She murmured into his chest, eyes drooping from exhaustion. He pulled back and gently moved her head to look into her eyes.

"Do this mean I'll live to see my next birthday?" he smirked as she glared. He would have to live in order to help Orochimaru find a way to help her rid herself of the demon.

"This will not happen again." Oboro said, stepping away from him.

"Agreed." Kabuto responded with a nod.

Little did they know how wrong they were. But for the time being, satisfaction would prove to calm the nerves and put their rivalry on hold. Only time would tell just how long the arrangement would last. It couldn't go beyond this night, this moment, for the consequences were far greater than the rewards of their need to feel alive. You live for so many years but death lasts an eternity.
