This will be the final installment of this story, so I hope I have done it justice for you guys!
Also this is probably one of the more intense and mature smut scenes I've written so just a warning that if you're not old enough (or mature enough) you shouldn't be reading this.
See you at the bottom

Itachi's heat emanating from behind her was as intoxicating as her earlier martinis. In a split second she thought back to when that same heat had her pinned to his bed, the heat of his tongue on her core, and the heat of his arousal inside her. She thought about how that heat would feel taking her from behind and found herself immediately turned on. She was pulled out of her thoughts as Itachi brought his chin to nuzzle her neck, and slowly dragged his hand from her waist up to her breast to lightly cup it.

"You've been wearing that for four years?" He breathed huskily against her neck.

She let out a relaxed exhale and allowed her head to fall towards Itachi's.

"Does it matter?"

He languidly pulled his nose up the side of her neck til his lips were over her ear, and pulled her waist closer into his.

"It's everything, Sakura."

She remembered he was still naked when she could feel his erection pressing into her bottom.

"Itachi..."

But before she could finish her sentence, she felt Itachi gently pushing against her torso until she bent over at the waist and needed to put her arms on the kitchen island to keep from falling over which left her in a very compromising, but not unwanted, position.

He kept an arm wrapped comfortably around her waist to help stabilize her and began massaging the sensitive skin behind her ear with his tongue and teeth. Sakura inhaled sharply at the feeling and felt how Itachi started to grind his hips against her rear.

Oh she knew exactly where this was going.

Itachi used his free hand to angle her chin towards his mouth and kissed her deeply. He had to pull her in quite closely and Sakura could now feel his entire front side pressed against her back. She began to move her hips with his and moaned in his mouth at the feeling. All thoughts of sleep had now left her and she was wondering how long he would torture her before she could feel him inside her again. Sakura decided the easiest thing to do would be to use a hand that was stabilizing her on the counter to remove the barrier of her pants, but Itachi had different ideas. As soon as she tried to remove a hand from the counter he released his grip from her chin and used it to hold her hands in place against the countertop. There was a slight break between their mouths and Sakura opened her eyes just enough to see Itachi giving her a smoldering look. His long, dark eye lashes covered half lidded eyes and his mouth was just barely open to inhale after kissing her. All of his intensity was focused entirely on her.

Kami he was sexy. She could feel the wetness between her legs increase.

"Are you too sore?"

Without breaking eye contact Sakura leisurely shook her head.

Itachi removed his arm from her waist and pushed the waistband of her pants down so they fell to the floor. He let her step out of the pants before using one of his legs to spread her feet further apart.

"Good."

Itachi took a moment to ready himself before he prodded Sakura's wet lips with his member. Of course he would want to fuck her while she was only wearing his shirt. Itachi would never be so possessive or controlling in their daily lives, but he occasionally would be in the bedroom and Sakura recalled it leading to some very memorable sex. She could barely hear the low 'tsk' sound he made in his throat through the pleasure of feeling Itachi slowly push into her again. She was grateful he took a moment to let her adjust again, and he tightened his grip to hold her hands to the counter with one hand while grabbing her hip with the other.

Then he began to move.

He slowly pulled himself almost entirely out before snapping, hard, against her backside. Itachi continued to snap his hip slowly and deliberately into hers and she could hear the sound of their skin when his hips met her rear. She arched her back further against his chest, closed her eyes and she moaned at the satisfying feeling he was creating.

Sakura could feel Itachi's tongue and mouth working a very sensitive spot on her neck and she knew it was going to leave a mark. There wasn't really a way to hide a hickey that high on her neck at work and she knew it would attract attention, but all she could think of was how badly she didn't want him to stop. The pressure it was creating on that sensitive area made her mind fog with lust and pleasure. She vaguely registered his tight grip on her hip and again thought of how it would leave a mark, but if it meant remembering this she wasn't overly concerned about it. But she was concerned about getting closer to him. The position they were in now was something she wouldn't forget anytime soon but Sakura wanted to use her hands to roam his body and kiss him more easily. At this rate, enjoying the feeling of being held in place by her assertive lover, her knees weren't going to hold up much longer.

"Itachi." She huffed out his name between breathy moans.

He either couldn't hear her or was ignoring her while he continued his slow assault of her most intimate area.

"Ita-ahhh-..Itachi!"

This time he slowed down to almost a stop; almost.

"Take me to your bed Itachi, I need to touch you."

She felt him release her hands from the counter and slowly pull out of her soaking core before turning her around and picking her up like a bride.

"As you wish."

Itachi leaned down to kiss her hard before he walked them to the bedroom once more. Sakura's dress from earlier that night was still on the floor but the pair hardly noticed as Itachi threw her current night shirt in a similar direction.

Sakura felt her back hit the bed and she grabbed greedily at Itachi's shoulders to pull him into her waiting core once again. He chuckled softly and crawled on top of her once more, positioning himself before pushing into her wet walls. They both moaned quietly at the contact and Sakura pulled him closer into her arms while wrapping her legs around his waist. They were now so close their noses were touching with Itachi buried deep inside of her.

"Sakura." He said her name as if it was the beginning of a question.

"Itachi."

He paused for a moment and she realized he was waiting for her to become a little more lucid from her lusty haze. Sakura looked up into his dark eyes and began to pick out short bits of emotion.

Lust, adoration, yearning, patience, affection, vulnerability, love?

"Sakura, I don't want this to just be tonight."

She didn't either.

"How long?"

"How long what?" He wasn't quite sure what she had meant.

"How long do you want this for? Want me?"

He suddenly kissed her with such a messy intensity she wasn't sure she could match it. She let him assault every inch of her mouth until she felt so thoroughly kissed all she could do was lay there, gasping for air, when he pulled his mouth and tongue away from hers.

"Always," He looked her dead in the eye.

"Always Sakura. I want you for as long as you will let me."

She studied his expression for a moment, committing it to memory as best she could, then kissed him again, sweetly this time.

Yes, she could see herself with Itachi again. It had always been him and it was always only going to be him.

She kissed him for a few moments until her pulled out of her.

"Turn around Sakura."

She had no idea how he made ordering her around so sexy but all she wanted to do in that moment was turn around.

Sakura positioned herself onto her hands and knees and waited in anticipation. Her core was hot and throbbing from all the attention she had received thus far, but she couldn't help to crave more. She could feel Itachi's weight sink into the bed behind her as he shuffled his knees into position. He once again slid smoothly into her from behind and took a hold of her hips as he began an unrelenting pace. There was something about that position and the speed that instantly had Sakura mewling in pleasure. She grabbed onto whatever her hands could find purchase in and pulled, trying to keep anchored to the bed. Before long she found she couldn't use her arms to keep herself upright anymore. Her head and shoulders fell into the super soft pillow where she continued to shamelessly moan as Itachi continued to pound into her without abandon. It was all Sakura could do to hold on and keep moaning.

All the sudden her hand pulling at the sheets was no longer keeping her anchored and she realized she had pulled the bed sheets off the corner of the mattress. Thankfully the bedpost was somewhat within reach as she let go of the sheets to grab onto something. Itachi slowed his pace down just enough for her to move then adjusted himself accordingly.

He kept his knees on the bed but moved them further up her hips so they were nestled near her waist. It created just the right angle for him to be able to stay inside her, but to reach forward and snake an arm under her armpit to delicately grab her neck with said hand.

"Tell me if it's too much, Sakura."

And before she could even think of a comeback he was applying just the right amount of pressure to the large blood vessels on either side of her neck and plunging into her again. She swore she was entering heaven. It should be illegal to feel that much pleasure. It was the first time she had felt the pleasure of being slowly denied oxygen and she found herself enjoying it.

Just when she thought she was running out of oxygen she felt a familiar rush telling her she was about to orgasm. Hard.

"Itachi! I'm-"

But before she could finish she felt a jolt of electricity run through her spine and her eyes closed tightly as her orgasm overtook her. It was one of if not the most pleasurable things she had ever experienced and just as she began to come down from the high, she could hear Itachi lowly moaning the way he did before he came.

She moaned softly as Itachi came inside her for a second time that evening.

An experience far too intimate for her to share with anyone other than a lover; other than Itachi.

She felt Itachi move off of her as he grabbed a tissue and waited for her to roll over. And waited..

"That good?" He asked.

She rolled over to glare at him and yanked the tissue away.

"Oh shut up. You and I both know it was."

He smirked at her, still in all his naked glory, and pulled her into his warm chest.

"It's always been you Itachi, and it will always be you."

He smiled gently at her admission and pulled her in to cuddle.

"Goodnight Sakura."

"Goodnight, Itachi."

Well that's that! Hope that was a decent ending for people.
I feel bad it took me almost two years to add another chapter so I tried to make it a good one.
