It's been nearly two months since Mark and Lexie began sleeping together. Sometimes he attempts to teach her something, and sometimes they just make love. Neither of them have been this happy in a long time, granted getting laid regularly does wonders for the soul. They've been getting busy so often lately that Lexie has stopped jogging, having no need for the extra workout now. She breaks a sweat almost every day with Mark either in an on call room or his place. Sometimes she sneaks him into Meredith's house, like she did with her second boyfriend Logan while she lived with her dad during med school.

Logan wasn't ready to tell his father he had a girlfriend because he wanted him to focus on his schooling, so he knew if he found out about Lexie shit would hit the fan in some way. They ended up breaking up during their second year of med school, the long grueling hours of study and stress had ultimately driven them apart, giving them a sour taste of defeat left in their mouths from his father's original reasoning. But they broke up before they'd had the chance to make their relationship public knowledge- he'd always only lever been a secret lover. She feels twenty four again, and it scares her to think things may end up the same way with Mark . It's pretty clear now that no matter how much she learns from their little "lessons" they're going to continue seeing each other.

Mark did teach Lexie. He taught her everything he knew, about men and women. "Just in case you may want to experiment some day," he'd added with a sly grin and a wink.

At first she'd not been particularly interested in learning about how to please a woman, but soon realized that listening to Mark would help her better please herself. And the key to having great sex is knowing about your body so that you can teach your partner. After a few nights together they had begun to take their time, falling into the rhythm of each others presence and becoming familiar with their likes and dislikes.

Her nipples. That was the first thing Mark learned about her. He's a quick learner, he has a reputation to uphold.

Lexie learned that Mark has a lot of tricks. He still pulls out random techniques every now and then that just blow her mind. She supposes it should bother her that he's been with so many women, but for some reason it doesn't. She's always known him to be a womanizer, that's why she chose him in the first place. That and her undeniable attraction to him physically and professionally. She adores his brain, unbeknownst to her the same as he adores hers. It's a very mutual attraction between the two of them. They are smitten.

She learned a lot about herself doing this with Mark, not just because he taught her but because he did this with her so often she had always new opportunities to pay attention. She learned there were things she loved and things she really did not care for, like anal. That was a horrible experience, thankfully he's doesn't care much that she's never trying it again.

Tonight, Lexie decides, she's going to go down on him. After nearly two months they still hadn't gotten to it. He'd never asked and she was always too eager to have him inside of her. But now that they've taken time, and its obvious that there's no stopping soon, she's going to do something she hasn't done since Alex. And hasn't actually done before Alex either. So far she's kept Mark interested, but this might make her look really bad, like the reason-Alex-forgot-to-add-her-to-his-body-count list bad. That kindally mentally scarred her and made her not want to try again. But tonight she was determined to overcome this fear. Still, when she showed up at his door with a bottle of wine and some pot she'd gotten from her cousin, she had cold feet. Literally, she couldn't feel her toes.

"It's open!" said a muffled voice from inside.

Mark made them dinner and they had steady conversation throughout. They'd gotten to know each other well these past weeks. She was charming, and he was full of surprises.

Steak and potatoes, asparagus on the side and a bottle of his own wine. He insisted they share that with their food because apparently he'd read a cooking column on it going well together. There was something about watching Mark with a knife that just tickled Lexie. Bodies, steaks, faces...he looks sexy cutting everything.

They continued their conversation on the couch for a bit before Lexie thought it the right time to execute the beginning stages of her plan. First she was going to loosen him up, then she was going to... well she assumed she'd figure that out once loosening up a bit herself.

"Ryan gave me a belated birthday present yesterday," she says casually, leaning for her purse.

"Isn't that your cousin that came to the clinic with alcohol poisoning?" He remembered this with a mocking laugh. "He was nuts. Funny guy," he adds admittedly, reaching for the bottle she brought, examining it. "Nice," he comments quietly to himself, twisting it expertly in his fingers.

She ignores his question, placing her items on the coffee table in front of him. "Do you have a cutting board or something?"

"Or something?" he repeats with a smile. "I have a cutting board. What do you want with it?" he wonders as he huffs from his spot, wandering towards the kitchen.

"I need a flat washable surface," she explains, taking inventory of her things. After a momentary silence she glances up at him. He's looking at her with a suspicious looking gaze, but still reached for the cutting board from his cupboard, handing it to her with a questionable glance at the things she'd laid out.

"Cigarellos?" He seemed shocked, and looks to her for explanation, and laugh creeping up his throat.

She rolls her eyes and pulls out the final item from the inside compartment of her purse. It was a sandwich baggy filled with something called... was it space something...alien something...oh, who knows?

He raises his eyebrows in pleasant surprise.

"Lexie Grey, are you going to roll a blunt?" he asks this slowly and carefully separating the words in mock disbelief, a playful humor in the back of his tone.

"Well I'm not making a bomb," she jokes, pulling the cutting board onto her lap, ready to begin her work. "I'm performing surgery. Cutting something open and making it better."

"Have you ever done this before?" He crosses his arms and watches her, waiting intently. She grins.

"Do you really think I'd perform in front of my teacher without practicing first?" She waits for his answer, confident in her skills. Smoking marijuana was her own secret lover. She enjoyed the novelty of preparing it, and the way it made her feel; calm and at peace. He seems amused, but shrugs for her to begin.

She sets to her work, reviewing the steps to bluntwrapping101 in her head with a surgeons mindset. She was performing this for a plastic surgeon of all people, so her work had to be immaculate. Most people used their nails to open the Cigarello, but she liked to use a box cutter. When she's finished it will look like nothing has changed, save the fact that it now has a filter and a considerable amount of marijuana in replacement of some cheap grape flavored wrapped tobacco. She liked filters, unlike most heathens.

When she was finished and satisfied with the result she handed it to an impressed looking Mark with a big sigh. She set the cutting board on the coffee table and reached for the bottle of wine.

~~~later

Marijuana makes Mark chatty, or maybe it was the wine. It made Lexie laugh to see him in such a different state of mind, giddy and excitedly talkative. She has had her fair share of practice with the herb, so it didn't affect her quite nearly as intensely as it did him. She had gained the upper hand. Her plan was working, she felt far more in control, more confident.

"I haven't smoked in maybe four ye- no wait! There was that time in Africa. That was right before I came to Seattle Grace." He remembers this with a look of nostalgia on his face, suddenly reliving his time overseas.

"What were you in Africa for?" Lexie had always wanted to travel and learn about different parts of the world. Anyone who's been anywhere plants a seed of interest in her mind.

"I was doing volunteer work at this huge rural farm, helping out with animals that'd been orphaned or abandoned by their mothers. Cats, big cats." He added that last bit excitedly. He forgot how much Lexie loved animals, especially cats. He's surprised he hasn't thought to tell her about his time over there by now. How could he have forgotten such a conversation piece?

"What kind of cats?" She has the most beautiful smile, the most hopeful face as she waits for him to continue speaking.

"Two lion cubs, one was six weeks old and the other was two months. There were some bigger lions in another enclosure, a few years old, and then the full grown cats in one as well. Two male lions, a tiger, and a leopard." She was enchanted.

"How did you get an opportunity like this?" She sputters. "Where can I sign up?" He starts to laugh but she was suddenly adamant. "Seriously, I want to go!"

"It was much more difficult than you'd imagine," he tries to tell her, "my tent was like twenty feet away from the adults enclosure. Do you have any idea how terrifying it is to wake up to the sound of lions fighting right next to your head?" he seems exasperated explaining this to her, like his words will never do it justice. "Here." He pulls out his phone and begins to swipe at it.

"What are you doing?" Lexie takes a rather large sip of her wine, feeling her confidence waning at the sight of the bulge in his pants. He wasn't even hard, he's just wearing basketball shorts.

"Listen," he instructs, holding the phone up to her. It was an audio recording he had saved from his trip. The sound of aggression and territorial dispute coming from these massive cats was not how she had heard it in movies, it sounded like two motorcycles had grown fur and legs and started sparring. It was horrifying, it was loud, and it sounded bloody.

"Oh my god they're killing each other!" she exclaims worriedly. "Why are they in the same cage?" Such a thing seemed unbelievable. Nature was such a raw powerful force, she suddenly feels like she hasn't seen anything.

"They do this every other morning," he shrugs, setting his phone down on the coffee table and reaching for his own glass of wine. "The keepers say it's fine, it teaches them how to behave in the wild, and they don't really hurt each other badly. Just a few scratches but no serious injuries, at least not serious enough to separate them. It was more concerning how much sleep I lost over it. It happened like clockwork just before dawn, when the sun had started rising but the birds weren't singing yet." He drinks more than he normally does, nearly emptying half of the glass. She watches him with amusement, feeling better again at his lack of restraint compared to hers. "My mouth is so dry," he murmurs in response once he sees her face, slightly embarrassed.

"Pot does that. It's why I brought the wine," she explains with a smugness, her lips twitching ever so slightly at the corners. It made something click inside of him. Like a warm vat of honey had been poured over his lower belly, his cock, and his thighs. His chest felt tight.

"What am I teaching you tonight, Little Grey?" he wonders out loud, not exactly meaning to change to tone of the conversation so suddenly, but why wait? He could feel the need creeping through his bones as quickly as consciousness takes him in the morning. Once he's begun to wake from his dreams there's no stopping it, and no going back.

She grins at him with a furious blush, finally breaking eye contact to finish off her glass and set it aside, instantly forgotten.

"Something new," she says softly, slowly moving across the couch to straddle his lap. He sets his hands on her hips and rubs absentmindedly at her sides, watching her face, waiting for her to say more. She slides her fingers down the sides of his face and neck as she kisses him deeply, tongue exploring his lips with expertise. They've had much practice.

"New, yeah?" he smiles.

"Mhmm."

~~~later

Mark was naked and waiting. She'd laid him back against his pillows and began to pull down his underwear, as slowly as she could possibly manage. He watched her with a deep anticipation, but also a little bit of wariness.

"There's something...different," he tries to say breathlessly, but she soon sees what he means, feels it. He's rock hard, not that firm spongy tenderness that shes used to holding. It was almost as if he'd taken something. Like a male enhancement kind of something.

"Whoa!" She strokes him, trying to mentally prepare herself for this change in the game. He lets out a shaky moan and it distracts her attention from this massive challenge she was contemplating.

"Shi-," he grabs her hand and attempts to slow her pace. "I think it's the weed. Or the wine. It's something, this is definitely not normal. I'm never this hard." He added the last part a bit quietly, as if almost saying it to himself in question. She could see the cogs turning in his head, trying to figure out what's done this. It was definitely the weed, it had to be. There were some strains that just make you horny, very horny. Of course that was the kind of strain Ryan had given her. Mark seemed deep in thought, breath wavering slightly at her strokes. She's done this before, bent between his knees to observe his manhood, study it, touch it. There's no reason for Mark to think she was about to slide it into her mouth, he's too busy wondering if she slipped something into his drink.

Starting at the base of his cock she slides her tongue flatly up the whole underside, licking at the frenulum in the same way he does her clitoris.

A very audible gasp from above, but she ignores him. If she looks up now she will lose her cool. So she moves on, wrapping her tongue around his head and swirling it around like it was a lollipop. He tasted exactly how she imagined he would. She continues to do this while stroking him, teasing him for a few moments before returning to the base of his cock, only to suckle each testicle into her mouth for a brief moment before focusing once more on the hard rod of arousal that protruded proudly between his legs.

She's satisfied with her beginnings, and decides now is the time to check on his reaction. It's only at this point does she realize he's been holding his breath, and the look on his face makes her want to cry. He was blushing furiously and a thick pulsing vein was throbbing on the underside of his neck. He's chest and abdomen were taught with strain, his hands tangled in her hair, desperate to maintain some kind leverage.

"Good so far?" she wonders, positioning herself to look as poised as she possibly good while kissing his erection. He closes his eyes and leans his head back against this pillows, visibly trying to stifle any outbursts while remembering to breathe.

"This is," he takes a deep breath, "this is new." He grins widely, an invitation for her to continue.

She'd done a fair amount of research on this before coming over tonight, and basically everything she read was something she had not previously known. No wonder Alex forgot about her. The general consensus of the internet was that if you wanted to take him in deeply you had to relax your throat.

Simple enough right? He seemed to be enjoying things so far and she's not gotten very far. Looking up to observe his reaction a bit more she notices his eyes are closed and his mouth open, eyebrows drawn close together. There was a crease in the furrow of his brow as he concentrated, chest heaving with silent breaths.

"Is it okay?" she wonders shyly, missing those sounds he makes. He was still abnormally hard, she hoped it wasn't making things painful for him. Shocked, he looks down at her.

"Are you kidding? I can't feel my legs," he laughs, "don't stop." Stroking her cheekbone with the pad of this thumb reassuringly, he tightened his other hands hold in her silky locks in preparation.

Lexie doesn't continue. Instead she pumps her hand around his slick length a bit quicker, a bit tighter, stopping to pause at certain areas of increased sensitivity. She wants to hear him moan first. She knows he's holding them back, and she's determined to pull them out somehow.

"You like that baby?" she murmurs in a low sexy voice. She refused to break eye contact with him, her carnal gaze was searing holes in his resolve like a plasma beam gun through a steel wall.

"Oh god yes," he says back with a growl and a suggestive nudge of her head towards his goal. She decides to edge him some more, enjoying her newfound position of dominance.

"I'm not sure it'll even fit," she teases girlishly, placing her tongue against the tip.

"It will baby," he says urgently, tired of her games. He pushes her head down in a not so suggestive way, adding once more, "just relax your throat. Right, the general consensus stands strong.

Breathing steadily through her nose and remembering those same three words, she becomes more determined than ever. If the universe wants to challenge her right off the bat then she's going to hit it out of the park and into a damn lake.

After the first minute or so Mark finally gave up on his withholdings, moaning and sputtering out profanities in a way that sounded like chocolate cake to Lexie, if chocolate cake could make noise. It took practice and time but eventually she'd made a considerable amount of progress. Mark was a very well endowed man, and this was much more than Lexie could've ever imagined she'd handle her first time, if any time at all.

She heard him attempt to say something, but instead of stopping her motions she simply hummed a tone in question.

"Lexie," he shuddered, "that felt so good." She gave a hum of satisfaction, the closest thing she could get to an answer without pulling her mouth away. "Oh!" Yes he likes that very much, she noted. Humming, she did read that.

After another minute or two she begins to notice a change in octave coming from Mark, a certain tenseness about his arms and the way he was holding the pillow by his head. There was an increased shortness in breath and he'd begun swearing more, as he did when he knew he was going to come.

But Lexie wasn't ready yet, once Mark came there was no way he's gonna be able to go for round two for at least a few hours, and she was ready for him now. No, he wasn't allowed to finish yet.

When she pulled away from him she almost regretted it after seeing and hearing his shocked disappointment.

"No baby please, don't fucking stop," he panted in desperation, trying anything to get her to come back to him. "Fuck, I'm so close, please."

Saying no to him was almost the hardest thing she's ever done, because on one hand the way he was looking at her is enough to give anyone a heart attack, and secondly because he was begging for it. But she remembered very clearly all the times he's made her beg, all the times he's brought her close to the edge and then torn her away from it for is own reasons. No, he deserved a taste of his own medicine, if even for a minute.

"No." The word tore through him like a bullet. He'd never been told no during sex before. Not once. "I'm going to make you come another way," she quoted him, lifting a cocky brow in challenge. He knew there was no defeating it, Lexie was calling the shots tonight. If she could say no there was nothing else he could do.

"Please," he whispered helplessly against her lips, wrapping his arms around her waist and pulling her close.

"Please what?" She pushes him back hard against his pillows, hovering above him and straddling his hips, her naked and slick arousal just above his, enough so that he can feel her heat radiating off. He attempted to buck up at her, but she leveraged herself on her knees, keeping him firmly away. "Please what?" she repeated firmly, holding her palm against the base of his throat.

He hesitated for a moment, giving her a few seconds of silence before leaping up, grabbing her in his arms and throwing her on her back before she could have time to protest.

Breathless, she attempted to come to terms with the new position, a started shriek came from her at first. It made him laugh.

"Please fuck me," he growls into her neck, kissing her all over while placing himself at her entrance, but waiting for her to answer.

She's silent for a moment, waiting, heart pounding in anticipation. He stops his attentions to her breasts and looks up at her in desperate question.

"Do it!" she says after realizing that's what he wanted, a confirmation.

He's sheathes himself in her deep and hard, drawing guttural moans from somewhere deep within.

"So hard and horny," he whispers to her after a moment of passionate lovemaking. "What's happening to me?" There was a small laugh, his breath hot against her neck.

"The weed," is all she can give him in response before her mind is led elsewhere. "Mark, don't stop," she cries against his chest, biting down on his shoulder to keep from screaming. It felt of something entirely different making love to him now, with his erection so. Her legs wrapped around his waist and his body pinning hers down, all she could see was his shoulder and his neck, his ears, the tips of them red with the beginnings of effort. He was grunting ferociously into her ear, her name sometimes finding it's way into the mix of garbled demands and pleasured outbursts. "Harder, I'm close. Yes, right there!" she digs her nails into the back of her neck, knowing he needs more than just words to inform him. He sometimes gets lost in the heat of it all and forgets to pay attention to anything but his pace. He exhales a moan in response, holding her neck in place so he can kiss her.

Her orgasm wraps around Mark like a kid going down a waterslide, deep and womanly bursts of ecstasy filled his room, bounced off his walls. She didn't necessarily squirt all over the place like women do on the internet, but there was an increasing rush of wetness that came with her spasms and contractions. She cried out against him, her thighs bracing against the repeditive impact of his body against hers.

He gives her a momentary break from his assault on her womb, knowing full well that this was no normal erection. "Oh, Mark," she whimpers into his lips as he attempts to kiss her once more before picking up his previous pace.

He was close. That dam inside his body is cracking, ready to crumble and open the way to a rushing flood.

"Lexie," he says, over and over between breaths. "Lexie." He knew he had to be careful fucking her so hard after he'd already made her come, it was that amount of wetness that'd caused their little accident in the on call room a month earlier. That's something he definitely never wants to think about ever again, but it helped him to learn, to make sure he doesn't make the same mistake twice.

So he fucks her deep. He buries himself in her, he feels her body constricting around him like a snake, squeezing pleasure from him like a boa squeezes like from it's victims. She screams his name, overcome with newfound intrusion after such a heightened stake of pleasure.

Warmth is creeping up his thighs, and before he realizes why he's not able to pull away from her, he falls apart in her arms, spilling himself inside of her. He comes hard for what feels like minutes, strangled moans and gasps falling from his lips into her skin. Or were the gasps hers?

He collapses on her in sweaty and trembling heap, small breathy moans still finding their way out of his throat. "Mark!" she exclaims as she realizes what's done.

But he can't hear her. He can't hear anything besides the sound of his own heart beating audibly against the inside of his ribcage, and he can't see past that blinding white light. Was this heaven?

"Did you just..." she begins, breathless and shocked, unsure what she should say.

After recouping a moment, he heaves himself up on his elbow and looks her adoringly. "I love you." He lets out a long sigh and smiles, kissing the side of her mouth.
