A/N: Day 2 of OQ Smut week! This will be part 1 of 2 ;)

Both of them know it's wrong. They are suppose to be trying to stay away from one another other, trying to forget each other and move on with their lives. It is the only way that Robin will be able to save Marian. For there is nothing else that Regina can do to save her, she's tried everything she can think of. And yet still they are drawn together, as they always have been. No matter the time or place Regina's heart calls out to Robin's and vice versa. They are powerless against it.

So they find themselves here, pressed up against each other among the books and magical artifacts of her vault.

It's only been a week since his wife's return. Seven days since he walked away from her. One hundred and twenty hours since he'd asked Regina to save her from the Snow Queen's curse. And already he is here, looking at her as if he can't bear their separation any longer.

"What are you doing here, Robin?" She questions. Her heart longs for him, every muscle in her body screaming at her to cross the distance separating them and take what is hers. But that's not who Regina is anymore. Not who she can allow herself to be if she has any hope of getting her happy ending one day. But oh how she wishes that Robin could be a part of that happy ending.

Robin shakes his head, lowering his eyes to the floor as he lets out deep exhale. He shouldn't be here. Why is he here? "I don't…" he starts, voice trailing off before he wearily admits the truth he's known since he'd made his decision. "I had to see you…"

Misery lances through her like a knife, a sort of agony Regina hasn't felt in a very long time. Doesn't he realize how painful this is for her? "Robin… We can't. You chose Marian. She's your wife and she's lying frozen right now!"

"Don't you think I know that!" He bursts. Robin feels like a complete failure. He hadn't protected the person he'd promised he would spend his life keeping from harm, neither here nor in the Enchanted Forest. And now he's letting her down again because despite everything he can't stay away from this woman, his soulmate. The last few days Robin has felt like a piece of himself is missing without her, worse than the loss he'd felt when he'd Marian had been taken from him. He hadn't realized that was possible and now that he's found her Robin isn't at all certain he can give her up. For a time he thought he could but every minute apart is torture.

Meeting Robin's gaze she sees the storm in the blue orbs as he says, "I'm supposed to love my wife, to do the honorable thing and uphold my marriage vows but, Regina, I can't. I love you."

Her heart leaps giddily in her chest upon hearing him confirm what she had known already. Robin had told her as much in her office before she'd ripped his wife's heart from her chest but to hear him say the words, to know that he means them is something she's never thought she would have. Regina's mind goes completely blank for the span of several seconds.

Then suddenly her lips are crashing into Robin's.

Neither of them are sure who had made the first move but it doesn't matter overly much when her lips are pressed flush against his, their tongues tangling and exploring before Robin breaks away to suck wet kisses down the column of her throat. His hands gripping hers, fingers flexing each time Regina lets out a tiny whimper of pleasure. Bursts of desire are exploding throughout her body, every where it touches Robin's and she wants him like she's never wanted anyone before.

Inching her hand up his back Regina tangles her fingers in Robin's hair, reveling in the feel of his lips pressed to her skin and holding him in place. Already she is slick and aching between her thighs, her body wracked with need. "Mmmmmm…Robin…"

Hearing the breathy way she says his name sends little slivers of possessiveness running through his body and Robin doubles his efforts against her throat, her collarbone, back up to her jaw. It's likely to leave bruises. Foolish considering the situation they find themselves in but he doesn't particularly care at the moment. Thinks only of marking her as his, physical proof that she belongs to him, just as he does to her. They are lost to each other, bound in a thrilling and terrifying way.

A minute later and Robin's lips are back to hers in a searing kiss that conveys every ounce of need and restraint and longing they've felt for the last week, all blown to bits the second they had allowed themselves to give in.

They should stop. Should end this before it goes any further.

Just the thought has Regina's heart clenching in protest and she knows that no matter how wrong it is, whether it makes them awful people or not, they are not stopping. Decision made her hands sneak their way up Robin's chest, skillfully slipping buttons undone as she goes and then his chest is bare and she is free to explore, running her fingers over the defined muscles.

Robin's hands have done some wandering of their own, easily slipping the hook on her slacks with his nimble fingers and sliding the zipper down. It allows him enough room to slide his hand into her panties, his fingers slipping through her wetness and they each let out a groan at the feel. Two of Robin's fingers quickly slip inside her, pumping steadily and Regina lifts one of her legs to wrap around his hip, allowing him better access. Her head falls back as she focuses on the delicious friction the in and out motion of his fingers causes her, probing her in such an intimate way but it feels amazing. And she can not wait to have him inside her.

Her head falls forward and Regina's lips connect with his stubbled jaw, peppering kisses along the line of it and down to where she can suck at this throat, loving the taste of his skin against her tongue, his pine scent invading her nostrils. Robin's fingers are still pumping in and out of her almost lazily as his thumb brushes over her clit and has little zings of pleasure ricocheting through her. But it's not enough. She needs more. Needs him.

Licking her way back up his neck until she reaches his ear she whispers into it, "Robin...I want...I need…" Regina's voice is breathless, almost whiny but he's now curling his fingers inside her and thumping them on that spot that has her vision going blurry and her brain turning fuzzy as she tries to focus her thoughts. Robin's determination to make her come only rises at the sound of her voice and he thrusts faster, feels her muscles tighten around his fingers as she rises higher and higher. Her forehead resting on his shoulder and Regina's shaky breath washing over his neck as she climbs toward that peak.

A few more rapid flicks of his fingers, several swirls of his thumb around her clit and she is tipping over the edge, her walls clenching and releasing around Robin's fingers as Regina cries out against his throat. Her body is tingling all over and as Robin's movements slow inside her she revels in the weightless sensation she feels, wrapping her arms around his neck. Regina brings her face back in line with Robin's and kisses him deeply, pulling him as close to her as she can manage. His own arm wraps around her waist more tightly, fingers slipping out of her, and they trade heady kisses for awhile.

It isn't long before Robin is subtly rocking his arousal against her core, seeking whatever friction he can manage where he's near to bursting for her. Grinning against his mouth Regina nips his lower lip between her teeth, enjoying the groan it elicits from Robin. Then the pair are being swept up in a purple cloud of magic, landing on Regina's soft mattress. It only takes Robin a moment and a quick glance around for him to realize she's taken them to her mansion. Straight to her bed, in fact, and he grins up at her where she's perched on top of him, straddling his hips.

If they are going to do this, and they most definitely are, they might as well be comfortable Regina thinks as she rubs her hands up and down Robin's bare chest. Right now though she wants him naked. She pushes at the material covering his shoulders and Robin quickly gets the hint, rising slightly off the bed to allow her room to remove the offending garment. Managing to steal a kiss from her in the process as well.

Humming lightly against his mouth Regina tosses his shirt across the room and breaks the kiss to shimmy her way down his body. Reaching for the waistband of his jeans she quickly unhooks the button and slowly slides his zipper down, enjoying the deep grunt Robin lets out as the side of her hand lightly brushes his erection. Her hands grip his pants and gently pull down, taking his boxers with his jeans, as Robin lifts his hips slightly to help. And then he is wonderfully naked in front of her and Regina smiles wickedly. It's such a wonderful sight.

"I think you have too many clothes on still, milady." Robin comments with a smirk of his own and her eyes lift to his instantly before she lets out a laugh. It's such a beautiful sound Robin's heart tightens in his chest just hearing it. How he ever thought he could keep away from her is beyond him because obviously he is a fool. His need for her greater than he's ever felt about anyone in his entire life and staying away from her is going to be impossible. He's already proven that hasn't he? Tonight won't be enough. Robin knows it with every muscles in his body.

But Regina is crawling back up the length of his torso, straddling his hips and leaning forward to murmur in his ear again, "Why don't you do something about that, thief?"

Robin quickly moves into action, promptly unhooking each of the buttons on her blouse and pulling it from her body, revealing the lace navy colored bra beneath. The material reveals just enough that he can spot the rose color of her hardened nipples through it and mercifully pushes her breasts up so the tops are spilling over the edge. Robin feels himself harden further at the sight.

Wasting no time he lifts his head to latch onto one of her nipples through the lace, sucking on it gently before he moves to pepper kisses along the swell of her breast, licking along the edge of her bra and dipping his tongue beneath it to tease. Regina moans and moves to unhook the clasp at her back herself, allowing the straps to loosen and fall off her shoulders while Robin sucks at her skin.

He quickly pulls the garment from her body, tossing it off the side of the bed, so he has better access to take her breast into his mouth. Robin sucks on the bud firmly, drawing a long moan from Regina as she rocks her hips against him. She's slick and aching. Is more than ready for him but wants just a few more moments to enjoy what he's doing to her.

Robin's right hand comes up to cup her other breast in his palm, alternating between tweaking the hardened nipple between his index finger and thumb and massaging her breast. He wants the hell out of this woman. Wants to suck and lick every inch of her body, make her come on his tongue and plunge into her all at the same time and Robin has no idea what to do first. Just knows that he needs to have her. "Regina…" he groans, releasing her breast with a soft pop and looking up into her brown eyes, several shades darker than their usual rich tone from desire.

She bends over to rest her forehead against Robin's, locking their lips in a heated kiss, tongues battling each other to feel and taste. Robin's hands slide down Regina's naked back, the tips of his fingers ghosting over her spine causing her to shiver. They slip further down to cup her ass in his palms, kneading them as Regina rocks her hips up and down his length, the seam of her pants pressing against her clit with each pass.

Upon deciding the offending garment keeping him from feeling her slick arousal against him needs to go at once Robin pushes her already loosened pants down her hips while Regina helps maneuver to kick them and her panties off at the same time.

There is nothing separating them now as Robin's cock slides between Regina's wet folds, a moment of instant bliss. He moans at the feel, arching his hips up as they simply rock together for several minutes. It isn't long before neither of them can stand this exquisite torture and Robin is cupping a hand around Regina's cheek, bringing her gaze to his.

He waits until her eyes, hazy with pleasure and need, lock on his before he's arching his hips upward and sliding inside of her. It feels like heaven, like coming home. In that single instant every doubt and worry that have been plaguing the both of them for days melts away and everything falls into place. This is where they are meant to be. Together.

The words fall from his lips effortlessly, "I love you, Regina. Gods, I'm so bloody in love with you." Robin's voice is full of strangled emotion. It nearly chokes him as Regina begins to move atop him, her own eyes glistening with unshed tears.

She wants to say it back, wishes she could let herself go enough to tell him how much she loves him but they shouldn't be doing this in the first place. And when they are finished he'll still go back to Marian and she will still be alone. Nothing will have changed. So Regina can't quite bring herself to lay herself bare to him that way. Instead she swallows the lump in her throat and pleads with him, "Touch me, Robin. Just touch me."

Robin's heart falls a bit at the fact that she did not return the sentiment. But if she won't accept his words then he will show her how much he means them at the very least. His hands roam everywhere, hardly stilling for more than a few seconds before moving on somewhere else in an effort to touch every part of her. Throwing her head back so her hair falls behind her shoulders Regina moans and rocks her hips up and down Robin's length. Slowly at first, enjoying the slippery feel of him filling her. He's thick and hard and feels amazing, stretching her walls as he slides in and out of her. She feels herself climbing higher and higher with every thrust.

For Robin she is a vision above him, one with the capability to drive him mad as he desperately plunges his cock inside her. Their hips are smacking together as they begin to pick up their rhythm to something that has both of them moaning and shouting out with each meeting of their bodies. When he brings a hand between their bodies, rapidly rubbing two fingers over her clit Regina lets out a shout that is music to Robin's ears.

Oh god. Oh god. Is all she can think as he rams into her. She's so close. So very very close. Regina frantically searches for Robin's hands, gripping them in her own and lacing their fingers together as she leans forward to connect their lips together. The shift in position has both his fingers and his length rubbing against her clit and it only takes a few more deep thrusts to have her crying out into his mouth as she topples over the edge. Her orgasm reverberating from where they are joined together through her entire body, pulsing steadily as he helps her draw it out.

Robin is quick to follow with a few more hard, rapid thrusts and then his hips are jerking against hers at his own release. Their bodies tingling in pleasure as the two come down from their high. Regina collapses on top of Robin in a heap of tangled limbs and hums appreciatively, turning her face into his neck and inhaling his scent. Robin wraps his arms around her slim waist in response and holds her tightly to him, placing a kiss to the crown of her head.

The two of them drift off to sleep not long after, neither willing to let their bubble burst just yet to face the harsh reality that surrounds them. And Robin whispers against her hair once more, just as Regina feels sleep dragging her under, "I love you, milady."

For just these few, intimate moments they will take care in enjoying each other. In showing each other that they love one another even when they shouldn't. Even when they have to go back to trying to stay away from each other.
