Akatsuki headquarters was practically dead, every single member was out on a mission at the time Itachi and Sakura arrived. It was June 9th, the sun was just beginning to arrive. The leaves were green with life, the earth was moist from the humidity in the air. Sakura had to remove her cloak due to the inclimate weather, as did her partner. The sweat beaded around her hairline and her skin was damp. Itachi showed no signs of discomfort despite the torturous heat.
The couple entered through the oversized double doors that created the main entrance for the establishment; they could only be opened by chakra signatures, and would remain locked down if there was an unfamiliar chakra trying to enter. Sakura's chakra was still fairly new, so only Itachi could get her inside. There was no air conditioning inside the hideout, but the fans and stony, windowless walls kept the air cool and moist. It was instant relief.
Not only did it feel better inside, but the atmosphere was peaceful. It was only Itachi and Sakura, no loud-mouthed Hidan or meddling Kisame to bother them. A kunoichi needs a break every once in a while.
Opening the door to his (their?) room, the Uchiha allowed Sakura to walk in first. Itachi was a well-mannered man. He liked being able to watch her walk, the way her hips moved and her hair swayed behind. She was no longer an object of lust to him, he realized that he did have some sort of emotional attachment to the girl. Of course, he hated it. It was a weakness. Any aspect of weakness, especially one so obvious such as a lover, would be detrimental to his success. Itachi hated the fault, but in all honesty, he wholly and truly did not want her to leave. When she'd told Kyuubi that she was planning to stay with Akatsuki, had she really meant it? Surely she did if she told that to him, even though it would hurt. Itachi decided he would ask her about this later, but now was not the time; he wanted her. And today was his day to have her.
Sakura turned around after hanging her Akatsuki cloak in the wardrobe and placed her shoes on the tatami mat at the corner of the walk-in closet. She was wearing a short-sleeved fishnet top with deep purple capri pants that bunched at mid-calf, held up with a belt. Pulling out the hair band, her long, pink locks spilled down her shoulders and back. Surprisingly enough, Sakura recognized that Itachi's gaze was on her. A playful grin crossed her face when she began to remove her belt, slow and meticulous.
Her actions caused a raised eyebrow from him, which only propelled her forward even more. Stepping lightly towards him, she removed her pants, revealing aqua and white polka dot panties that hugged her hips and accentuated her long, milky legs. Itachi's eyes went from Sharingan red to onyx gray; he did not want to know what she was planning to do next. The thrill of not knowing her actions made it all the better.
The smallest smile played on Itachi's lips as he watched his blossom strip down. He was hungry for her; after all, it was his special day. At this point, Sakura was down to her panties, covering up her bosom with her hands. Stepping towards Itachi, pressing her body against his, she let her hands drop and curl around his shoulders. Her lips pressed against the strong neck, kissing that eventually led on to flicks of the tongue and small love bites.
Using the arm around his shoulders for balance, Sakura slid her had down to Itachi's waist band, slipping her fingers underneath the mesh of his shirt to caress the skin of his chest. The muscles of his abdomen rippled at the touch of her fingers. Letting out a low groan, Itachi pushed Sakura onto the bed, playing with the elastic of her panties.
"Let me make love to you, Itachi-kun," Sakura managed to breathe the words. The situation was so hot and heavy, she writhed underneath him, subconsciously grinding against him. Every touch was memorized and savored, and she began to feel dizzy with lust. "I won't bite... Unless you want me to..." chuckling at her joke, she nipped his jaw.
"Fuck, Sakura, let me have you," Itachi lost control for a moment, letting his lust get the best of him. He bent down and left an angry red hickey at the nape of her neck, then another at her jawline. He thrust his hips into hers, causing a wave of pleasure to resonate between them. Gradually, he kissed down her body; her lips, her jaw, her neck, the valley between her breast, her abdomen, her pubic bone. Then he stopped and looked up at her before sliding the silken panties down her legs before tossing them across the room. Sakura was now naked, while he was still fully clothed. It only turned him on even more.
Dipping his head between her legs, Itachi began to taste her. Sakura's back arched in pleasure, cocking her head back while placing her hands on Itachi's head. "Oh, Ita-kun," she moaned his name, quite loudly. He fastened the flicks of his tongue, Sakura's body twisting in ecstasy.
After a few moments, Itachi slid back up her porcelain body that was damp with sweat. His lips crashed against hers in a fervent, passionate kiss. Their tongues danced while Sakura removed Itachi's belt and unzipped his pants. She settled herself over him at the perfect angle, letting him enter her tight womanhood. The sensations caused him to muster out a moan. Sakura pulled him upwards by his collar while riding him so he was sitting upright and kissed him with lustful intentions, moaning into his mouth and whispering his name. Itachi's hands grazed her back and butt, making their way up to her hair. "Itachi," she could only get out his name as he pulled back her hair and he bit her lower lip.
"I'm going to-," Sakura rolled her hips against Itachi's one last time before climaxing. He'd came with her, closing his eyes and cocking back his head. Their breathing was causing the mirror in the bathroom to fog. Heat radiated from every pore. They shared one last kiss, Sakura placing one hand on his cheek whilst the other became tangled in his black waterfall of hair. Itachi's hands remained around her bare waist, holding her body close to his.
"Happy Birthday, Itachi-kun."
