(Yandere x Yandere)

Obito stared bitterly at the trio talking in the living room. He was in the doorway to the kitchen, loudly and angrily unwrapping a chocolate granola bar.

(Y/n) smiled shyly as Itachi and Kisame explained their mission. She always seemed so coy, but Obito thought it was cute. Until she acted that way around other men, that is.

Obito, however, did know that she wasn't always like that. Alone with him, she was more outspoken, and in battle, she wasn't shy at all, bold, even.

"We'll see you later, (Y/n)-chan." Itachi said expressionlessly. 

How dare he call her '(Y/n)-chan'... That was what Obito called her.

Obito knew that Itachi liked her. Everyone in the Akatsuki liked her. Even Konan, being with Pein, certainty wanted her, Obito was sure of it.

And she was always so nice to them.

It made him sick.

"Try not to get killed while we're gone." Kisame said, turning toward the exit.

"Bye, guys..." She smiled.

As soon as they were gone, Obito was behind her, and she turned around, "Tobi? Is there something you need?"

"Oh, Tobi would like to speak to (Y/n)-chan privately!"

She blinked, "Tobi, there's no one else in the hideout..."

"But we should go to Tobi's room!" He grabbed her hand, pulling her down the hall. She had to notice the strong grip he had on her hand, and how his hand dwarfed hers.

He pulled her into his room and slammed the door. His grip on her hand tightened, "Ow! Tobi, let go!"

"Tobi doesn't want to let go." His voice darkened, now a deep voice that she'd never heard.

She didn't really know what to say or do. Itachi, who she loved, and would do anything for, her savior, was not here. She didn't trust Tobi.

And she shouldn't.

And she knew it...

But...

But she really liked his deep voice. "Tobi-" She was cut off as she was slammed against a wall, Obito's hand wrapped around her throat. Her hands wrapped around his wrist, as she tried to kick him away, but to combat this, he simply stepped closer, placing his feet and legs between hers, with one forearm placed beside her head, and his hand still firmly wrapped around her throat, but not enough to really hurt her... eh, yet.

"Who are you and what the fuck did you do with Tobi!?"

"I am Tobi."

"You're not Tobi! Tobi's a nice person!"

He laughed darkly, "Tobi's a criminal. He's not a nice person."

She was breathing heavily, scared, yes, but also...

She could feel his entire body against her own.

And she liked it.

She had forgotten about Itachi, now.

He was nothing like this man.

He was nothing to her compared to Tobi.

This was it.

She found the one.

She was certain.

Obito, on the other hand, was too enraged to notice how good her body felt against his.

"The other Akatsuki members... are you in love with any of them?"

"Not anymore, I'm not..." She whispered.

His eye narrowed, "Do you care for Itachi? Have you fucked him?"

"No, he's nothing to me."

"You're lying to me!" Obito shouted as his fist made contact with her face. He punched her about three times before grabbing her collar with one hand, placing his other beneath her thigh as he lifted her higher against the wall, "You're mine. Don't you understand!?"

She was panting, the taste of blood invading her mouth as a small amount trickled down from her swollen lips, "Yours? I'm yours?" She laughed, and he growled at her. He pulled her off of the wall to slam her back against it, but before she was slammed against the wall, she disappeared, and he swiftly turned around, only to be nailed in the side with a foot, subsequently knocking the air from his lungs.

He fell to his knees as his hands went to his side, she had obviously Chakra kicked him. She then hooked him beneath the chin, which knocked him back against the wall. "You seem a little confused, so let me explain it." He could hear the venom in her words, and his eyes met hers, intrigued. She straddled his hips and pressed his wrists against the wall, not that he put up much of a fight- he wanted to see what she had to say.

"You're mine, Tobi." He growled at her again, his Sharingan flaring, "I've... ensnared you, have I?" She chuckled, "In that case... Your body, mind, soul... They're all mine, now. You can't claim ownership, because I already have. Now sit there and keep quiet so I can heal your broken jaw, you bastard."

He glared at her as her glowing hands rested against his jaw, which was, in fact, broken, in multiple places. He contemplated pinning her down and putting her into a Genjutsu, but he still wanted to let this play out, so he restrained himself.

When she was done with his face, she lifted his shirt, moving her glowing hand over his bruised ribs. As soon as he thought she'd healed him sufficiently, he pounced and pressed her to the floor, "Breaking you will be fun..." He said. He had his hand against her throat again, merely to show her that he had the control.

His lips met hers harshly, and hers fought back just as rough. His legs were between hers, and he pressed his body against hers as firmly as he could. Her legs wrapped around his hips as his tongue slid between her lips, against her tongue and teeth.

He had both of her hands easily pinned against the floor with a single hand, which she was trying to pull away from. She wanted to run her hands through his hair, and over his torso, but he refused to release her wrists.

She moaned as he ground against her, and their lips broke apart, their lungs burning from the lack of air. He released her hands, placing his forearm against the ground as he leaned toward her ear.

"You're mine..." He insisted.

She laughed maniacally, "...Hm...I have a proposal..."

He side-smiled, mischievously, "What makes you think I'll accept?"

"We kill the Akatsuki..." His eyes widened, but he remained silent, "And then we can be together, forever... Equal ownership..." She pulled his face toward her own, her breath fanning out across his lips, "We can be Alone..."

His grin returned, "Killing the Akatsuki to prove our love... and equal ownership? That's your proposal?" She nodded. "Deal."

She took hold of his hair, tilting his head back, to which he growled, "If we're doing this, you have to promise me that I'm the only woman who's ever on your mind, Tobi."

He pressed his body closer to hers, leaning in toward her ear as her grip loosened on his hair, "You're the only one. You're not just the light, you're the darkness and everything in between."
