Chapter Five

It isn't necessarily a secret—their relationship. And if it is, then it's the worst kept one.

Ever since Robin had moved to NYU from Columbia, and Regina finally accepting the fact that she can't run away from what she feels for him and what he feels for her, they'd been more open about their relationship. They don't necessarily scream it out to the rooftops, not necessarily tells everyone that they are together, but they don't deny it when asked. But they had introduced each other to each other's son, and that had gone swimmingly—both boys had become fast friends, bonding over comics and superheroes.

It had been a blissful few months of them being together, with play dates and dinner dates, and sneaking off from their kids to have some alone time together. It was great, Regina felt loved and she felt free to love, and really, all in all, there was nothing to complain about. In fact, she had every reason to be happy, which she is.

That is until she'd come to pick Robin up at NYU after a long day. They are going out that night for a date (his insistence), and instead of him having to pick her up, and then schlep them both back to the restaurant when it was the other way from Columbia, she offered to pick him up instead.

He'd texted her about half an hour ago, saying he was just in the library, doing the last bit of homework he could do before their night. She walked to the campus library, wary of the fact that this isn't exactly her turf, but feeling ridiculous as she thought so. It isn't like she's snooping, or anything as stupid as that…sometimes, her fantasies really do just run wild.

She fishes her phone from her bag and dials Robin's number as she nears the library. She places the little device against her ear, and waits as it rings, and rings. Robin doesn't pick up however, and when she looks at the entrance of the building, she realizes why.

Her heart stops, and her blood runs cold, and for a moment, she doesn't know what to do.

She watches as her boyfriends stands at the entrance, talking to another woman, his hand resting against her shoulder. Regina won't have minded, it could be very innocent, she's known Robin to be very affectionate, always initiating body contact, even in the smallest form, and she trusts Robin, except, the woman leans over him to give him a tight hug and a peck on the cheek that from Regina's perspective, seemed to linger more than necessary.

Regina tries to reason with herself—they could be old friends. It isn't uncommon for a woman to be kissing a friend's cheek. Hell she does it—to her brother in law, David, and had seen Robin's friends do it—with Ana, Will's girlfriend. That woman, with her slender body showcased by the clothes (or the lack thereof) that she's wearing, and her blonde locks, and red lips—she could just be an old friend.

And Regina almost believes that, until the woman moves back and then forward, to press her lips against Robin's.

The world starts to spin on its axis, and Regina feels like there are walls closing in around her, even when she stands at a very open space.

She couldn't breathe.

And she thinks back to the days prior, of how he's been so distant lately, and how he smells of another woman's perfume, and how…well she'd ignored the signs and turned a blind eye to them because she'd been under the impression that they were, are, blissfully happy.

Boy, is she wrong.

She wonders now how she could have fallen for it, how she could have let herself believe that there is a second chance at love for her after Daniel. She isn't the kind of person who gets second chances or happy endings, and to be honest, Henry is enough. He should have been. Asking for a companion had been a shot to the moon, and she'd been dead wrong.

There's a voice at the back of her head that maybe she's taking all of this out of context, but she doesn't listen to that, not now, not when she's trying not to fall over as she runs away from the scene, from her boyfriend….from everything.

She makes her way to the car with no accidents, and drives away, not bothering to give Robin a call or anything. She drives home while tears pour from her eyes, and for a moment she gives a silent thanks to her sixteen year old self who had mastered the art of crying and driving without crashing.

When she gets home, she calls her sister, asks if she could keep Henry all night (because she can't let her son see her like this), and when Mary Margaret teases her that of course, she's already planned on that since she knows Regina either won't be able to make it home, or won't want her son around for the after date activities, Regina barely manages to choke back her sob (the image of Robin's lips pressed against that blonde playing over and over again in her head like a broken record, managing to break her heart repeatedly), and says she'll pick her son up in the morning. If Mary Margaret finds anything odd about the way she sounds or about her actions, she doesn't bother to find out as she puts the phone down and takes it off the hook. She even turns her cell phone off, knowing Robin would try to reach out and ask her why she hadn't gone to pick him up. She doesn't know how to tell him that she'd caught him on the act, cheating.

It's all a mess, and the rest of the night becomes a blur, because try as she might, Regina couldn't resist the call of alcohol. She needs to bury her feelings, bury them deep down where she can't see them, until she's on her own, or she has to face it again. She doesn't want to fall apart, most especially in front of her son.

Her son.

His son.

What do they tell them now?

Maybe she's being drastic, she tells herself as she drowns another glass of whisky (and god, even her drink reminds her of him), maybe there's an explanation to all of this—but how does one explain a kiss like that, without spelling out that he's found someone else?

There is no way, she decides, and then takes to the bottle of whisky, pouring herself glass after glass, until drinking from the glass felt too tiresome that she just drank straight from the bottle. She doesn't know how much she'd had to drink, and she didn't have the time to find out, as she passed out, drunk, on her kitchen floor, lying down, just under her island counter.

…

He isn't sure what happened.

Regina is supposed to pick him up, but she hadn't showed up, and he'd tried to call her but her cell phone is off, and her telephone seemed to be disconnected. He'd been worried at first, then that worry turned to anger, then to panic, to anger, before finally shifting to deflation because it's apparent that she's avoiding him.

And for the life of him he cannot figure out why.

So on a bright and early Saturday morning, he makes his way to his house after leaving his son in the (hopefully) capable hands of Will. He doesn't know what he'll find, so even when Roland had begged to see Henry and his Regina, Robin had decided not to bring him.

When he finally made it to Regina's house, he'd sat in his car for a few minutes just to gather his courage. For all he knows, Regina could have just forgotten, but Regina's memory is as sharp as her tongue, and it's hard to believe that she would forget. They already have very precious little time together and they'd talked about her coming to get him that day. He feels something might have gone wrong, and he just doesn't know what it could be.

When he finally gathers enough courage, he gets out of his car and walks down the cobbled steps that lead to her door. He raises his hand and knocks on the door, but after a few knocks, she still doesn't open the door. His heart races, and he moves his hand down to grasp the brass knob and turns it. When he finds it unlocked, his panic intensifies. What if someone had broken in and hurt her?

Oh god.

He doesn't even want to know, can't even imagine.

He runs inside and calls her name wildly, but receives no response. He walks to the kitchen but finds it empty. He is about to go upstairs when he notices a pair of feet just behind the island counter, and he walks there to find his girlfriend passed out. He feels as though blood has drained out of his system as he runs over and picks her up in his arms. He checks for injuries and sighs in relief when he finds nothing. It is then that he finds the bottle of whisky that's rolled over on to the side. He leans just a little bit to sniff her, and sure enough, she reeks of alcohol.

Sighing, and trying to figure out what went wrong and why she'd drunk herself to stupor, he stands up and carries her up to her bedroom. He lays her down the bed and works on getting her clothes off to make her more comfortable—it's obvious that she just went straight for the whisky without bothering with changing her clothes. When he's sure that she's a bit more comfortable, he makes his way downstairs to get her a glass of water and some aspirin for when she wakes up. He also makes her some food that he keeps warm in the oven, and then goes back up to wait for her to wake.

…

When Regina wakes up, it's to fingers running through her hair and a marching band beating inside her skull.

She tries to open her eyes, and is coaxed by a soothing voice she cannot place in her sleep and alcohol addled mind. When she does however, the events of yesterday come back to her, and she feels the sharp stinging pain in her chest again, and she rolls away from the hand as far as she can as though they have personally offended her.

She even tries to get out of bed but finds that with the hangover, that task is impossible to do. So she huffs and tries to push down the feeling rising from her stomach into her throat. Without a word, she is handed a glass of water and a couple of advil, which she downs quickly. She closes her eyes and waits a little bit for her mind to feel a little bit more balanced before she opens them back again and stares at the confused pool of blue eyes staring back at her.

Yeah, right, like she'd fall for that.

(She will, and this resistance is a practice in vain.)

"Get out," she tells him in a cold voice, trying as she might to make herself sound cold and unaffected—like she's not slowly, little by little falling apart inside.

"Regina…" he begins, reaching out to touch her but she moves away from the bed (regretting it when she feels her world tilt a little), and puts some—a lot—of distance between them.

"I said get out Robin," she reiterates, and juts her chin, facing away from him. She bites down her bottom lip to keep them from trembling.

"Regina, please, talk to me," he begs, "What's gotten you like this? I understand that nothing is okay, right now, but if you could please tell me why, because I have been trying to come up with reasons you're being like this, something I might have done, but I come up with nothing."

She looks at him, suddenly feeling angry, eyes blazing. "Ah, so making out in front of you library with a gorgeous blonde is nothing wrong? Is it a fucking hobby?" Her voice rises at every inflection and she watches as Robin flinches before realization dawns on him. She scoffs. "That's right Robin, didn't think I'd catch you, did you?"

"Regina," he pleads, crawling over the bed to get to her side. "There is an explanation to this, perhaps if you would just listen to me, please." He sounds desperate, like she literally just told him it's over—which it will be in a minute—and Regina tries to fortify her will.

"And how would you explain it without you sounding like a cheater?" she asks ironically, and moves back when he stands before her.

He moves forward, and then she moves a step back. She throws him a warning glance, and he throws his hands up in the air.

"Look Regina, okay, you've seen what happened yesterday outside the library, but why didn't you come to me and ask me?"

"Ask you what? If you still wanted to stay with me when you so clearly found a younger model? Ask you to stay and make a fool out of myself?" she says, staring at him as anger poured out of her. Her head is still pounding, and she doesn't really want or need this at this time, but what else can she do? "We all know what we are, Robin! A dalliance, a thrill, and now that that's gone, party's over, you're moving on to another. I just had hoped you would have the decency to tell me that I'm being replaced!"

She doesn't mean her words, but she's wounded, and quite frankly so jealous that she almost feels her jealousy pouring out of her, and she's just lashing out, but it isn't like she can scoop up her words and put them back in her mouth. So she just stands her ground, even as he backs her into the wall, his face looking nothing but angry at her words. She knows him not to be a violent man, and she knows he would never hit her, but at that moment, she is almost scared of him.

He looked positively murderous.

And it's even more obvious at the way his words are ground out as he spits them to her face. "You think this is what it is? That this is just about fucking you?" he asks, as he takes another step forward, and she another step back. "You think I moved to NYU so I could fuck another woman because I'm tired of you?"

She doesn't answer, only looks up at him and swallows. His anger is vibrating off of him in waves.

She feels the wall against her back, and she stands on her tiptoes, as he braces his hands on each side of her head, effectively trapping her between two hard surfaces—the wall, and his chest (which is accentuated by that t-shirt he's wearing, but now is not the time to focus on that).

He swoops down so that their mouths are level, and her eyes flicker, falling shut as arousal starts to pool low in her belly. Her breath hitches as he moves one hand to grasp a fistful of her hair.

"You think every time I bury myself balls deep inside of your wet cunt, it's me doing anything but making love to you, and every time I eat that hot pussy of yours, I do it with every intention of moving on to the next thing in a skirt that moves. You think…that every time I trust in and out of you and you roll your head back, and you arch your back, that's fucking?" he growls, and good god, she shouldn't find it hot, but she does, dear god forgive her, she does. "I'll show you fucking, Regina. I'm going to take you, hard, deep, fast and rough, right against this wall. I'm going to tear out your clothes and fuck you until you beg me to stop. And when I do stop, you're going to forget your own name."

She swallows and then thrusts her chest against him, finding courage and brazenness in places she doesn't know she'd find them (mainly, she doesn't what parts of her still had them). "You're all talk and no walk, Locksley," she tells him, turning her nose up at him.

That does it.

His mouth descends to capture her lips in a heated kiss, and she hasn't really fully registered anything before his tongue is prodding and sliding inside her mouth, tasting and testing her, not leaving any part untouched. His hands are frantic as he rips the pajamas she doesn't even remember getting into off her body and throwing them down on the floor. Her own hands are no better and are moving in their own accord, as they basically shred his tshirt off his chest, letting them pool at their feet. Next to go are his pants, and her bottoms, and before a whole three minutes pass, they're both down to their underwear.

His mouth is insistent, but teasing, and he draws back to place hot sucking kisses down the column of her throat. She knows he will leave a mark, but at this point she doesn't even care as she claws at his back. He lowers his head further and kisses her breasts, playing with her as he licks and licks but never quite where she wants him too. One of his hands come up to palm her breasts, the feeling of her nipple rubbing against his skin, making her buck her hips just as he pulls the other nipple to his mouth and sucks hard. It feels so good, she thinks, moaning as she wraps her legs around his naked torso.

He runs his hand down her body until it finds her sex covered by lace. He moves her panties aside and starts running his index finger up and down her clit, making her throw her head back and for her eyes to roll back in pleasure. She's wet, so fucking wet, and she can feel her muscles clench with the need to feel him inside her.

His fingers then slide inside her, pumping in and out, and she can't help the soft scream that escapes her throat as he fucks her. She needs more, wants more, and she decided to get exactly what she wants, moving her hand down to grasp his hard cock, pumping up and down, in rhythm to his fingers thrusting in and out of her.

She doesn't last long with the assault on her pleasure spot, and she cums within a few more thrusts, her cum spilling to his hands, and his mouth muffling her scream as he kisses her breath away. She's panting, chest rising up and down in erratic rhythm but she doesn't get a moment, because before she knows what's happening, he's inside her, pumping in and out. It doesn't hurt, of course it doesn't, she's so hot and wet for him, but it does take her by surprise, making her moan aloud, before she manages to catch up and thrust against him, in and out, hard and fast, deep and rough. She is holding on to his shoulders, her nails no doubt leaving marks, but she doesn't care, she's getting fucked out of her own wits, and it feels so fucking good as he pounds into her again and again. His face is of pure concentration, and hers is of pure pleasure, especially when he tilts her hips and he starts pounding onto that sweet spot that makes her cry out because of how good he makes her feel.

"Yeah, baby, do you like it when I fuck you like this, huh?" he asked, though he needs no answer. She nods, either way, unable to form any answers at the moment.

His mouth is on her neck, sucking against the succulent flesh, leaving bruises she'll have to cover up, and she thinks she'll return the pleasure later, but right now she focuses on the pleasure happening a little bit further south. The sound of skin slapping skin is loud against the quiet room, and occasionally one or both of them would moan and groan, or she would let out a soft scream when she feels him hit her gspot again and again, until she could feel herself cuming right there against the wall, in his arms.

"OH yeah, ungh, yes baby, oh yes fuck me, urngh, right there, oh yeah, god, oh fuck," she screams as he pounds and pounds into her and she could almost feel it—feel herself tumbling over the edge of precipice, her mouth opening to let out a scream, her muscles contracting inside her, milking him as he rides out the last of her orgasm while thrusting inside her, until he too cums, spilling all of him inside her.

She's tired, so tired, but so well fucked, and she feels like she's in heaven, boneless as he carries her to the bed and lies down on it with her, spooning her. She falls asleep with a smile on her face.

…

Robin wakes and opens his eyes to find two pairs of brown eyes staring at him. He smiles, and moves a little, even when his muscles protest (it's been rather an intense fucking session), and he pulls her closer to him, dropping a kiss on her forehead.

"I love you, Regina," he murmurs. "Very much, and I'm not going to leave you and move on to the next woman, a younger model as you say. I will never leave you."

He could feel her shoulders deflate, as she looks up at him and stares at him, her lips forming a pout. "But I saw you Robin, you kissed her! Whoever she is!" The green eyed monster is rearing its ugly head again. "And then there had been days, I ignored it and told myself that it was nothing…because I trusted you, but for days you would be distant, and I can't reach you, and sometimes you smell of a woman's perfume and it's not mine!"

"First of all, she kissed me, I didn't kiss her," he said, his voice soft and leveled. His hands are running up and down her back. "It all happened so fast, one moment she was just thanking me, in what I thought was a friendly hug and kiss, and then the next moment, she was kissing me square on the mouth. When I realized what is happening, I pushed her right away. I was prepared to tell you. I tried to call you so many times, but I always get directed to voice mail."

She looks at him skeptically, and he sighs (later, when they are no longer preoccupied, she'll check her phone and realize that he is right, he'd told her that there had been something that's happened and he wanted to tell her about it).

"I have only been distant, because I wanted to pass this subject I was partners with this girl on. I don't want to have to retake in on the summer break because I want to take you and our sons away for a while, a little vacation just the four of us. So I'd really been concentrating. And again, this girl is my partner in this class, and I guess her perfume is overpowering that you smell it off of me, actually, I don't guess, I know her perfume is overpowering, because I try not to choke on the smell everyday. I know that I have failed you, that that little scene had somewhat given you a reason to doubt me, but I promise you, there is nothing going on with me and her. You're the only one that I want."

"But she kissed you," she repeats petulantly, not because she doesn't believe him but because she' can see it play over and over again in her mind's eye and it makes her want to pull all that girl's hair out.

"I pushed her away no more than a second after it happened and told her in no uncertain terms that I am in a happily committed relationship with the love of my life," he swear, and maybe he's right, she certainly hadn't stayed that long to try and find out. "I don't ever want to kiss anyone else but you, I don't want anyone else but you, baby."

He rolls over so that he's hovering above her and kisses her lips softly before kissing the tip of her nose.

"I love you," he murmurs.

She wraps her arms around her neck, sighing, as she feels her heart piece itself back together. She knows she should have trust him, and though she knows she might have had the right to feel jealous, she thinks now that maybe cutting him off and not hearing his side might have been a little drastic.

"I know you're scared to fall deep, to get hurt, to be burned, because you've been hurt so many times before, but you can trust that I will always try to protect your heart. I could never believe how you could let a common thief like me steal something so valuable, but I'm glad you're not trying to get it back." He looks at her with his heart in his eyes. "I don't even want to give you a reason to be jealous, and I never want to hurt you okay? So whenever something bothers you, talk to me. I always want to help you."

"Silly," she says, smiling. "You can't steal something that's been given to you, remember?" She sighs and she pulls him closer. "I love you Robin. I'm sorry I was jealous."

He smiled as he rolled over again so that she is lying on top of him. "It's okay, trust me, I'm not immune to jealousy either," he says, making her look at him in confusion and surprise. "Oh yes, you have no idea how many times I've wanted to throttle Graham Humbert and Jefferson Hatter for even breathing the same air as you."

She laughs in surprise and shakes her head. "You don't have to worry about them though, as I am yours completely," she tells him sincerely, leaning down so she could kiss him fully.

"As I am yours as well," he tells her, looking her straight in the eyes.

She smirks at him and moves down to whisper in his ear. "But if I catch any girl sniffing around you once again, not only am I going to tear her apart, I will break both your arms too," she threatens, half seriously.

He laughs at her and agrees, before he takes her again, this time more lovingly, and if Regina leaves a few little (okay, a lot big) marks on his neck, well then she's just confirming the world's worst kept secret, right?
