OK there was NEVER meant to be a fourth chapter, but clearly my brain had other ideas and well it is/was Christmas. This REALLY is the last chapter. I hope you enjoy it and dont wish I'd left it at three...

"She knows what she's doing".

His own words reverberated around and around in his head as ADA Rafael Barba's anxiously watched Olivia Benson standing at the rain lashed window. Even in the dimness of the room he could see her face was etched with concern, as lightening once again struck, illuminating the space, he noticed the distant regret in her brown eyes.

It wasn't the first time today, glancing at his watch on the nightstand, yes it was still today, that he had found himself doing this. The situation was of course entirely different, and in many ways, it was much harder on him now, than it had been watching her through the toughened glass of the interview room, some hours earlier. His concerns then had only been for his friend, what she was putting herself through, the memories she was recounting whilst dealing with Laurel Linwood. Those concerns were still very much for his friend, at least he hoped she was still his friend, but they were also for himself. Had he ruined not only their very special working relationship but their equally special friendship?

She'd assured him that "this wasn't about today", but the lawyer in him couldn't help but ask questions, what was this? And if it wasn't about today, then what was it about?

Earlier she had stood in the stark unfeeling surrounds of the SVU interview room, save the pelting rain against the barred windows, her boots on the hard floor had been the only sound in in the small space, her dark suit and shirt accentuating both her authority and her professionalism. Now she stood in his tastefully decorated bedroom. Her feet bare on the large rug which covered the polished wooden floor, the rain still pelting, and the only sound to be heard in this room.

His powder blue shirt, was dry now, those little dark circles long since gone, it was just a little creased from being discarded onto the floor. Its rounded edge now fell respectfully just below Olivia's bum, she'd turned up the cuffs, and from where he lay on the bed with the aid of a modest bedside lamp, he could see she had fastened a couple of buttons, it accentuated both her beauty and her vulnerability.

Barba shifted uneasily against his pillows, for once, really not knowing what to say. Whether Olivia heard him move or if it was another flash of lightning which disturbed whatever her train of thought was, he couldn't be sure, but her reflective brown gaze fell upon him, it came with a gentle smile, soothing his anxiety.

"I didn't mean to wake you." She said, her soft voice drifting across the room in the semi darkness.

"You didn't." He assured her, returning her smile.

"Are you okay?" He ventured

She nodded. "You?"

Her simple question seemed a lot more direct and loaded than his had done, perhaps it was the seasoned policewoman in her, or perhaps it was just that she knew Rafael Barba too well.

Everything that went through his head seemed to be the wrong thing to say, sounding as if he were in some way questioning her judgement or her reasons, of course that wasn't it, but if what they had shared had just been a knee jerk reaction to the day, he would understand, he would respect that. He had to.

Not for the first time today, the usually skilled wordsmith found himself at a loss for them, he too simply nodding.

Barba watched as Olivia padded across the space between the large paned window and his bed, her bare feet not making a sound in the thick pile rug, the innocuous but ridiculously sexy action sent strange thrill though him.

He felt a cool rush of air across his upper body as she slowly pulled back the sheet, her chocolate brown eyes holding his, a penetrating intensity replacing any trace of regret, the coolness he'd felt quickly replaced with the warmth of her body as she straddled his bare midriff, shifting until she was comfortable.

Naked beneath his shirt, he felt her damp feminine heat against his lower belly, the movement had caused the powder blue material to stretch open, there were those two low fastened buttons, but the others remained tantalisingly open, and Barba's green eyes were drawn to her breasts. He noticed her take a long slow breath, and his eyes once more returned to her beautiful face.

Olivia's hands rested in the centre of his chest, her thumb and forefinger twirling a few strands of his chest hair absently between them, she seemed mesmerised by the action as she spoke quietly.

"Perhaps." She said slowly. "This was about today."

The strands of hair between her fingers were twirled in the opposite direction, Barba remained silent, quite literally, the position she was in, left him in no doubt that this was not a mistake or something she regretted in any way, but whether it was for her benefit or his, she wanted to say something.

"We've shared so much."

Her thumb and forefinger relinquished their hold on his chest hair, tracing a slow deliberate path upwards, her eyes followed them, eventually meeting his.

"I know you too well Raffa, at some point, maybe even at more than one, you were thinking I was only here because of what happened today." She paused briefly

"You were right, but you were also wrong."

Her fingers gently stroked his strong jawline, another innocent action which connected erotically with his lower body.

"I am here because of what happened today, but because it took what happened today for you to bring me here."

Olivia inclined her head to one side, in a gesture which all but dared him to answer her, he didn't.

"On another day neither of us would have pushed this, we'd have gone to Forlini's, had our usual quiet drink, picked over the bones of a lousy day, and then gone home…...maybe a little annoyed with our self again, and frustrated."

Barba felt her shift her weight slightly as she spoke, emphasising her words, or one of them at least.

"You're right." Barba admitted, his voice a little hoarse, his mind a little distracted.

Of course, she was right, about all of it.

"I did think that more than once, but, I didn't want you thinking I was taking advantage of the situation, of you, because of what had happened today, catching you at a low point, however frustrating it might have been."

The gentle curve of her mouth and warmth in her eyes was understanding.

"Just now, standing at your window, I found myself thinking back over today, over many other days and wondering why I hadn't found myself standing here like this before… in your shirt. So much time wasted."

A plethora of emotions surged through his sensitised body, surprise at her frank admission, how could he not have known? That wall of professionalism was clearly higher than he thought. Understanding, the regret he'd seen reflected in her eyes, regret that they had not done this before. What an idiot he had been.

His green eyes drifted over his shirt, yes why hadn't he found her wearing one before? She looked so goddamned sexy in it, his body twitched at the thought and at her touch.

Olivia's hand was on walkabout once more, back to whence it had come and lower. Her voice was quiet and husky as she spoke.

"Other than bringing me here, what happened tonight really had nothing to do with today, but it made me realise you were the person I wanted and needed to be with… And as for low points…"

Olivia once again shifted her weight, Barba couldn't withhold the small groan which slipped from between his lips as her warm gently rounded arse brushed against his hardening flesh. Instinctively he arched towards her, the gentle, reassuring smile which had curved her sensual mouth, drifted into an almost feline like grin, as she rubbed herself against his burgeoning erection.

There was nothing small about the groan which slipped between his lips this time, her warm wet flesh abrading against his, as he once again arched into her. There was no pretext either, sitting astride him she was in the dominant position and in complete control, Barba didn't mind in the least. Even if there was the merest hint of doubt in her words, which as her hand moved exploratively over his body, there wasn't, she certainly had the upper hand in every sense of the expression. The ADA was quite literally in her hands, and more than happy to lie here and enjoy that feeling.

His hands rested on her thighs, her silky skin beneath his fingers, the sight of her aroused him beyond belief. He had no desire to remove his shirt, it really did looke so incredibly sexy on her, just those two tiny buttons fastened at the navel, tantalisingly showing off her firm breasts, they were just too much of a temptation, and he slipped his hands beneath the expensive cotton, cupping them appreciatively, brushing his thumbs over the inviting peaks. As the material skimmed his own skin, he thought how much he would enjoy wearing this shirt again.

Olivia rose at his firm touch, her back arching, as she pressed into his hands, bending forward to kiss him, she took his mouth with an exquisite sense of authority, as if convincing him of her words. He was more than happy to accept her assurances, as for his own sharp tongue, right now he had a much softer use for it.

Every bit of his body felt so good against her own, so welcome, that want and need for him overwhelmed Olivia once more, his mouth moved unhurriedly over hers with the same erotic precision of the hands and fingers which kneaded her aching breasts. She manoeuvred herself backwards feeling him press at that very centre of her need. She could feel her own gushing desire and was more than ready to have him fill her once more.

The angle of their bodies was so very different this time, he seemed even bigger and harder than before, perhaps her body was just more attuned to him, even more in need of him. Impaling herself on him, a mixture of beautiful intense pain and all-consuming pleasure shot through her, his rigid, deeply sheathed flesh hitting and caressing every sensitive nerve.

Her body spoke to him with that same deep understanding and connection that her voice always did. That voice now calling his name in a series of pleasured moans, her body hot, wet and constricting around him in uncontrollable pleasure. She took her own gratification from his body, hers silently telling his exactly what she wanted, his only too pleased to comply. Her satisfied groans, and writhing movements excited him all the more, encouraging him to thrust harder and faster, her own arousal coating him, allowing him to push in deeper and deeper, her inner walls like a firm silky hand about his pulsing flesh. Her own fast approaching climax drove her to ride him with an almost ferocious intensity, the momentum flowing into his own body until a cloud of pure white ecstasy engulfed and shattered around him, shaking and then stilling him with the same violent force.

Rafael Barba fought for his breath and his equilibrium, his heart beating so wildly in his chest it felt as if it were trying to escape, he felt Olivia's hand cover it, warm and gentle against his heaving ribcage, her equally warm face eventually replacing it, her soft hair fanning his upper body.

As he slipped from her body she slid down his, her heart beating just as wildly against his stomach, his spent flaccid body, resting against the flat planes of hers, brushing the cool very creased cotton of his shirt, a satisfied smile curved his sleepy mouth. Her familiar unobtrusive fragrance once more filled his nostrils, it mingled with the powerful scent of sex.

"She knows what she is doing."

The words drifted around in Rafael Barba's brain, the satisfied smile, now replaced by a very sleepy one.

She certainly did he thought, gradually drifting into the arms of Morpheus and wondering about making up for the time they had wasted…
