AN: Y'all had better stop pestering me for a multi-chapter story now.

"But Addison… it's been four months. Four months of injections and vitamins and supplements and sticking a thermometer up my vajayjay every goddamn day, four months. How can I not be pregnant yet?" Callie Torres huffed at her best friend slash OB slash fertility doctor.

"Cal, honey, it takes time." Addison Montgomery, all six feet and flaming red hair poised for comfort, both as a doctor and as a friend.

"You said I was, how did you put it again, 'abundantly fertile,' and Arizona, well… you said she was… what?" Callie asked, knowing full well what Addison said.

When Callie had first broached the idea to Arizona, they'd both been drunk, when Callie had blurted out that she wanted Arizona to be her sperm donor. The blonde had looked at her with shock, genuine and real shock when Callie practically shouted the words. They promptly fell into giggles and another bottle of wine, moving to the actual donor files that Arizona kept making horrid and inappropriate jokes over. The next morning, still lying on the couch where she'd slept, Arizona had asked if Callie were serious, a tense nod and one breathless moment of eye contact and silence later, the blonde nodded once - more to herself than to Callie - and agreed.

Then she'd shown up to every appointment at Addison's clinic and donated her sample, kissed Callie's forehead and wished her luck, and then left with a wave over her shoulder. Four times she'd done this, and she promised that she'd do it as many more times as Callie needed.

"Aggressively fertile… like… damn." Addison replied with a chuckle.

"Right! We're ripe for making babies and yet… no baby." Callie moaned, the frustration getting to her. She wanted at least two kids, and her romantic history had not presented the partner for her. Unlucky in love, she'd decided to make the leap herself at 27. She still had time to find someone, Addison had said, but she was young and healthy and independently wealthy, now was the time.

"Cal…" Addison warned.

"I just… am I doing something wrong?" Callie asked.

"No, Callie, sweetie… you're not, and you will get pregnant, I promise… but there are things you could do." Addison offered.

"Like?" Even Callie could hear the desperation in her own voice.

"Do you orgasam after the insemination?"

"Yeah, yes. I drive home and I get in bed and I do it!" Embarrassment was no longer an issue in their relationship. "Sometimes twice just for good measure!"

"Clitoral or vaginal?" So maybe embarrassment still was an issue.

"Does it matter?"

"Studies show that vaginal orgasams can help the process. It's obviously not a guarantee since some women are incapable of vaginal orgasams, and have oodles of children, but it can help. Can you have vaginal orgasams?"

"Yes, not often, but it's happened." What she didn't want to say was never with a toy or by self stimulation. It had always been with someone directing the penis, be it attached to a person or a strap on.

"So, then, try that today. Like I said, it's not necessary for conception, but it does help. Plus there's more options. IVF, we fertilize your eggs outside and then implant them. Or…" Addison hesitated and turned slightly so she wasn't quite looking at Callie but she wasn't not looking at her either.

"Or what?" Callie asked, finding it strange that her friend wouldn't look at her.

"Sex."

"Like… sex sex?" Callie asked shocked. "You want me to go find a rando and what… lie?"

"You could ask Arizona?" Addison offered. The blush rising on her cheeks matching the one on Callie's.

The brunette could clearly remember the look on Addison's face after learning of Arizona's secret. When they first came to her, Callie returning the donor files with the blonde in tow, Addison had been nothing but professional and kind. But then she said she'd need to examine Arizona as well, for viability purposes. It was strictly medical, she'd said, and though Arizona had only hesitated for a second, she agreed. Callie had left the room then, and fifteen minutes later Arizona left the room, a weird smile hooked on her face, and zipping up her pants. She'd whispered good luck to Callie and then left. Back in the room Addison's eyes had been wide and shocked, neither of them would explain what happened even though Callie had asked dozens of times.

But suggesting that she have sex, like actual penis in vagina sex with Arizona Robbins, it was laughable. It was absurd.

It was kind of intriguing.

"Sex has worked for procreation since the beginning of time, it's not a guarantee but it's a proven method to make a baby!"

"You want me to have sex with Arizona." Callie said. It sounded like a question, but really it was a statement.

"I want you to try having sex, you're the one who wants to use Arizona as a donor. I suggested sex with her because of that!" Now they were both flaming red from embarrassment, the flush on Callie's cheeks matching the burn in her vagina… it's not like she'd never thought about it, not in an 'I want it' way, in a 'people fawn over her and the rumours are a lot' kind of way. But they were friends, friends who didn't have sex.

Though it wasn't like friends donated sperm to help them become single mothers, either. So who knew what was appropriate.

"Either way, we have this sample here, I'm gonna do my thing, you're gonna go home and do your thing and hopefully fifth time's the charm and we can both forget about that." Addison whispered, the sample cup practically yelling "Robbins-Torres" at her from its position on the table beside her. Arizona had come and gone, or should she say cum and gone?, a kiss to the forehead and a good luck.

"Yeah." Callie offered, leaning back on the table and opening her legs so Addison could do her Dr. Montgomery thing.

"Something to think about." The red head offered, slipping on her latex gloves and preparing to inseminate Callie.

"Yeah, something to think about."

four weeks later

"Thanks for coming over, there's just some things I need to talk to you about," Callie said, welcoming the shorter blonde woman into her home.

She was still not pregnant. After her appointment with Addison, she'd tried the vaginal orgasam thing, unsuccessfully and eventually achieved the citoral orgasam… but it still didn't work. Not that she was expecting it too. For Callie it seemed that the universe was against her happiness. Not that she was prone to overdramatics, but she was losing hope. In love and having a baby… five months… well, she couldn't help it.

"It's no problem Calliope!" Arizona said, a brief hug shared between them, "You promised pizza and beer, and you know how much of a slut for pizza and beer I am."

Callie lead them to the living room, a laugh spilling from her lips, but she could feel the tension coil low in her belly. Not from arousal, but fear and trepidation. She was ovulating again, and though she was sure about what she wanted - the sex with Arizona to make a baby - she wasn't sure how Arizona would feel about it.

Plus, she was mostly sure that she shouldn't just spring this on Arizona right now.

"Are you okay Callie?" Arizona asked, her blue eyes scrunched in concern. It was those eyes, and the soft dimples that made Callie ask Arizona to be her sperm donor. Arizona was strikingly beautiful and though Callie was sure her Hispanic genes would dominate a child they made together, she hoped that some Robbins would slip through. The eyes maybe, hopefully for sure those dimples. "You seem tense."

"Yeah, yeah… well no… can you hold off on the beer for a second, please." Callie asked, sitting on the couch beside Arizona. Close enough that the blonde was able to place a comforting hand on her knee, but far enough away that the Latina could gather the courage to ask Arizona to have sex with her.

Which was a strange thing to ask. She'd asked other people to fuck her, in all kinds of ways, and she'd asked people to make love to her…. But she'd never asked someone to just have sex with her for the sole purpose of making a baby. How do you say that?

How do you say that to one of your best friends? Your friend who you've already asked to jerk off into a cup once a month? Your friend who said she'd do it, but didn't want to be a parent?

Your friend who you kind of maybe were attracted to physically, and had at one point considered a romantic interest in, but who was also kind of a player? Your beautiful and hot friend who you thought about last time you masturbated because your other friend and OB suggested that you have sex with to make a baby, the baby you hoped looked at least a little bit like the first friend and the idea of doing it, of having sex with them made you come extremely hard?

How do you ask for that?

"Callie?" Arizona asked again, sliding a little closer on the couch.

"Will you have sex with me?" Just blurted out. Callie felt her face flush with embarrassment, her entire body warming and her hands beginning to tremble a bit with the flush of what she'd just said. That probably wasn't the way to ask for it… even if it was directly to the point.

"Sorry?" Thankfully the blonde hadn't pulled away from her, and despite her immense hesitation, Callie persisted.

"I'm not pregnant, and Addison said a whole bunch of things about IVF and vaginal orgasams and sex, and how sex is the tried and true and old fashioned method of making a baby, and since injecting the you know… your… you know… whatever, isn't working, even though we've only tried five times, and I know the appointment is tomorrow I just thought we could try it, but I don't know, I just -" Callie cut herself off. The longer she rambled, the wider those blue eyes she loved got, the slacker the soft and sloping jaw got, the dimples kind of disappearing as she went on.

"Sex?" Is all Arizona said.

"You don't have to, we can keep doing it this way, it was just a suggestion, I don't know, I shouldn't have said anything." Callie tried to backtrack her words.

"No… it's okay," Arizona whispered, once again sliding closer to Callie. Now their knees were touching, and though her brow was scrunched in concentration and something else Callie couldn't read. "I just… I…"

"Seriously," Callie said, gripping her friend's hands with her own, "Forget I said anything, let's just eat and forget I said-"

"I didn't say no, Calliope," Arizona said, cutting Callie off. Hope flared in her chest, bright and hot and a flush of arousal shot through her. It was a unfamiliar sensation where Arizona was concerned, but she knew it was mostly to do with the hormones she was taking, the fact that she was ovulating right now, that maybe she would get her baby soon. "Is this seriously something you want?" It had almost very little to do with the fact that it was Arizona. Almost practically nothing even. Even though the compassion on the blondes face was maybe partially to blame. Definitely hormones and not at all even a little bit Arizona.

Looking deeply into her friends face, Callie started, "I want a baby." Arizona just nodded. "I… I know it hasn't been that long, but Addie said that sex… and you know… and you, and me, and I just... "

"You want a baby," Arizona finished, her hand slipping a bit higher on Callie's thigh. Maybe it had a little more than a little to do with Arizona.

"Yeah." Callie whispered, ducking her face from her friend.

A beat of silence passed between them, the room filled with the tension and expectation of Arizona's answer.

Callie shivered when she felt warm fingers caress her cheek, tilting her face and eyes back to look at Arizona, the look on her friends face taking her breath away. It was the same way she looked at her when she agreed to be the sperm donor, the same smile she had when they'd done the genetic testing, the same way that Arizona always looked when she was helping someone.

The same smile that prompted Callie to ask her when they were drunk. The same smile that made Callie smile.

"Okay," was all the blonde said, and Callie couldn't contain the sob that bubbled out from her chest, a mixture of relief and happiness. "How do we do this?"

"You've had sex before," Callie laughed, relieved that some of the tension in the room disappearing, pressing herself closer to Arizona.

"Not like this," Arizona laughed back, strong arms wrapping themselves around the Latina's shoulders, holding tight and making Callie feel safe and warm and protected. "I meant, when? I know you have a calendar for your ovulation schedule with Addison, but when?" Arizona asked, her hands sliding up and down Callie's arms.

"Oh… well… right now?" Callie said, once again flushing with embarrassment.

"Hence the holding off on the beer?" Arizona laughed, easing the embarrassment from Callie's shoulders. "Where? Here? Your bed?"

"Bed, I think." Callie offered, and in response Arizona just stood and offered Callie her hand.

"Lead the way." Their hands didn't release each other on the journey, the pizza and beer forgotten in the living room as Callie led them to her room. She hoped she remembered to clean up. Though she had hoped the blonde would say yes, she hadn't expected it to happen this quickly. Even if that was the entire point of asking Arizona over tonight.

Once in Callie's room, the lights off but the full moon bathing the room with soft light, enough to make out the blonde's profile but not make out her facial expressions, they stood apart with the door closed behind them.

"If you're not sure, if you're having second thoughts, or it's too awkward we can stop Arizona. I'm not, I'm not trying to pressure you or anything," Callie whispered and was surprised when Arizona pressed a soft and chaste kiss to her lips, the space between them eliminated with two short steps from the smaller woman.

"I'm sure Calliope," Arizona said, her fingers slipping under Callie's shirt and pressing against the bare skin of her lower back. Rivers of shivers and electricity following the wandering path of pale fingers, their chests flush against each other and the surety of the blondes words evident against her hip where Arizona's erection was pressed tightly against her, another flood of arousal seeping out from her wanting pussy. "I was just thinking about how to make sure this is good for you."

"Arizona, you don't have to-" Callie was cut off by her own moan as Arizona's fingers brushed up her back and with the swiftness of a practiced hand unsnapped her bra with a single flick and her lips pressed a hard kiss to a flushed neck.

"Addison said reaching orgasam is important. Obviously from me, I'm a sure thing Callie, I haven't had sex in six months… but it's important for you to finish, I want to make sure you come. I want to make you feel good."

Callie wanted that too, but if the rumours about Arizona were true, or the way her hips were squirming or her clit was throbbing or her nipples were begging for attention were any indication, that wouldn't be a problem. But that wasn't foremost on her mind. "Why haven't you had sex?" She asked. More like stuttered and groaned when Arizona's teeth nipped lightly on her earlobe.

"Do you trust me Calliope?" Arizona breathed right into her ear and it almost made Callie come right there.

"Mmhmm, yeah." Callie could hardly breathe anymore. In the last five minutes she'd gone from being a mess of nerves and fear to being unbearably turned on, and she couldn't even blame the hormones anymore. It was such a fast turn that Callie couldn't wrap her head around it, all she could was lean into the feelings. This is what Addison said after all.

Slowly her shirt was lifted over her head and soft lips, the softest lips she'd ever felt were pressing butterfly kisses over her now exposed chest, teasing her nipples and not quite making contact. Her bra had fallen down somewhere, Arizona having already undone it, the garment falling to the floor between them as Arizona's hands undid her pants and her knuckles pressed against her core. The two layers of fabric between their skin not enough to stop the thrill of electricity and need pass through Callie. All the while those lips never left her skin, and Callie's fingers never disentangled from the shirt of the smaller woman.

When she found herself naked in the middle of her bed, a half clothed Arizona hovering over her, one of Callie's nipples in her mouth the other being played with by fingers and pinches and rolls, she was surprised at how awkward this wasn't. It felt natural to be doing this with Arizona, despite the purpose of it. She knew that the love and affection she had for the blonde was mostly platonic, the one time romantic feelings passed, but the way her body was responding to the blonde and the way that Arizona seemed to intuitively know what she wanted and need without Callie having to say or ask was simply winding her up.

They had their moments of fumbling and awkwardness, but the laughs shared between them made those moments pass quickly and only heightened her arousal and need for Arizona. Not just for the baby they would hopefully be making, but for the woman about to make it happen.

Arizona was settled between her legs, her face inches from Callie's wet pussy, a knowing and confident smile on her face, one blonde eyebrow quirked over lust darkened blue eyes and Callie knew she was in for a world of pleasure. "Still trust me?" The blonde asked, and Callie could only nod. Arizona's back was bare, the expanse of creamy flesh spotted with random freckles on display, the swell of her ass half exposed and the elastic of her boxer briefs sticking out from under the undone jeans.

"Oh god," Callie moaned, lips wrapping around her clit and sucking. Not hard or gentle, just enough to rile her up and make her demand for more. When she did, a single finger slipped into her, curling at just the right spot to make her vision darken and her entire world to focus on her throbbing sex and her fingers tangled in blonde hair.

Without warning, Callie's hips jumped against Arizona's mouth as she added a second finger, nonsensical sounds escaping along with moans and please from Callie as Arizona continued to fuck her. The orgasam building in her was overwhelming in its force. She hadn't been with anyone in almost a year, since she made the decision to have a baby, she'd been limited to self stimulation and toys… and having another person, especially someone she was familiar with and enjoyed their presence and company… well it was coming. Fast.

"God, Arizona, I'm gonna, fuck…" a third finger was added and the stretch and pull in her pussy was burning her up from the outside and with a hard suck to her clit Callie was flying, tipped over the edge into oblivion and a low moan tumbled from her open lips as she came, her inner muscles clamping down on the fingers struggling to work inside her.

Coming back to herself when Arizona's fingers slipped from inside her, she sighed with the loss, but her entire body felt relaxed and weightless as Arizona shifted over her, the rough denim of the jeans rubbing against her sensitive inner thighs as their hips pressed tightly together, the erection between them hard and pulsing slightly. She'd never seen Arizona's cock before, she hadn't known how well endowed her friend was, and though she'd felt it once when Arizona was soft, she wasn't prepared for how big she actually was.

Suddenly she understood the shocked look on Addie's face after her exam.

"You okay Calliope?" Arizona whispered against her jaw, where she was once again pressing open mouth kisses, and Callie couldn't help the way her face turned in to lean harder against the lips.

"I'm excellent." She whispered back, wrapping her own arms around the smaller body on top of hers.

"I have to tell you something." Arizona said, while Callie's hands roamed the exposed back of the woman on top of her, slipping onto the soft skin and firm muscles of her ass, gripping the flesh there and was pleased when Arizona bucked against her with a moan. "I've never… without a condom… I might come just from that."

Callie chuckled and moved her hands to the front of Arizona's jeans and underwear, finally dragging her fingers across Arizona's cock. She moaned with Arizona feeling how big and thick it was. Expectantly waiting for Arizona to fill her, and somewhere from the awkward start to this encounter to now, it stopped being about making a baby.

"Cal, sweetie, that isn't helping," Arizona husked and groaned pressing her forehead into Callie's neck, the Latina suddenly filled with the need to make Arizona come. To explode in her hands or her mouth, even though she knew where she needed Arizona to explode was neither of those places.

Without warning Arizona rolled off of her and her bed and stood, her breasts and chest heaving as she looked down at Callie still spread eagle on the bed. Callie could feel her pussy glistening in the cool air with her wetness, could feel her clit still twitching every now and then from the orgasam Arizona just gave her. "I want to see you, please."

Though the room was dark, the moonlight still flooding in lit the blonde enough for Callie to see her nod, and then slowly lower her pants and boxers, her erection flopping free and bouncing against her toned abs before coming to rest just slightly to the left of her belly button. If she felt huge… it was nothing to the sight of Arizona's erect cock, standing proudly and hard as Arizona kicked her clothes away. The whole sight of her was intoxicating. Firm muscles and taught planes, but soft breasts that Callie wanted to taste, creamy and pale flesh she wanted to explore and memorize, and the biggest cock she'd ever seen. The circumcised head red and throbbing, slight twitches every now and then.

But she was on a mission, they both were. "Come here," she asked, wanting all of those things, unsure if it was the post coital haze she was in or the mere sight of her friend poised to help her make a baby.

"Seriously, Cal, you're gorgeous, and it's been so long… I need a minute." Arizona husked, one of her hands resting just above her cock on her stomach.

"Come here Arizona," Callie asked again, and the blonde finally moved back to the bed, Callie reaching for the smaller woman's body and directing her where she wanted the blonde. Settling her between her raised legs, hip to hip and breasts to breasts, Callie looked into her eyes and tucked an errant strand of blonde hair behind an ear, the throbbing cock now sliding through her folds, both of them moaning at the sensation.

"If you come, you come, just stay inside." Arizona nodded mutely against Callie forehead, and tensed when the Latina reached between them and gripped Arizona's cock, guiding it to her entrance, her hips rolling of their own accord, trying to pull Arizona into her.

"Ready?" Arizona husked, and Callie was unsure if she was asking her or herself. So she answered anyway, moving her hands down to Arizona's ass (when had she fallen in love with that ass, so firm and soft at the same time) and added a bit of pressure to let Arizona know it was okay.

With a single roll and thrust of her hips, her cock was buried deep in Callie, an "oh fuck," leaving both of them. The throbbing in her pussy intensified and she didn't know if it was her or Arizona or both of them, but by the way Arizona stilled, Callie was sure that she was honest about possibly coming on the first thrust.

"I just had a moment of panic about not wearing a condom," Arizona admitted, the hands holding her up over Callie pressing into the mattress, her arms shaking with the effort.

"Me too, even knowing why… my body is like… danger Will Robinson, danger." Callie replied, pulling a short laugh from the blonde above her.

"You okay?" Arizona asked, compassion and concern in her eyes. Callie had been right about Arizona being the biggest she'd ever seen, and now she knew that she was the biggest that had ever been inside her. It was almost painful. Almost. It might have been if she hadn't already been wet and had come from the blondes mouth and fingers, but muscles and nerves inside her that had never been touched or stretched like this were awakening. It was exciting and thrilling and causing a wave of fluid to flood from her, causing a need for Arizona to move. To fuck her.

Part of her wanted Arizona to make love to her, but she pushed that aside. This was only about making a baby.

"I'm good. You?" Callie asked back, rolling her hips against Arizona drawing another moan from both of them.

"Fuck, that feels good, you feel amazing, can I move?" Arizona husked, lowering their foreheads together.

"Please," even to her own ears it sounded like she was begging, and Callie honestly didn't know that she wasn't.

It started slow, the gentle thrust in and out, and Callie knew from the few thrusts that she would have that vaginal orgasam that Addison had told her was so important. Every stroke out building the raging inferno in her, and every thrust back in sparking another blaze.

"Harder," she begged, this time knowing that she was begging. And Arizona answered by reaching down and lifting Callie's right leg up around her hip, never once stopping her thrusting into Callie. The brunette lifted her own left leg and wrapped both around the woman fucking her, ankles pressed tightly against thighs and ass urging Arizona to fuck her harder and faster, her nails digging and scratching wherever they found purchase on the body above her.

This wasn't how this was supposed to happen, she knew. She was supposed to come with a vaginal orgasam, and she was going to, of that she was certain, but for Callie this had turned into more than just sex to make a baby. It was like she was having sex for more than that, like she was actually allowing her feelings to get involved. Feelings long since dormant we're coming alive, and no matter how much she tried to force them back down, every hard and deep thrust from Arizona was forcing them back out from the box where Callie was trying as desperately to stuff them as she was holding on as Arizona fucked her.

"I'm close Arizona, so close, god you're so big and you feel so good," Callie husked, her lips grazing the shell of a sweaty ear as her words caused Arizona to pump faster.

"What do you need?" Arizona grunted.

"Kiss me," Callie asked. Feeling Arizona press her lips to the shoulder she was nearest. "On my mouth." Except for the first chaste kiss Arizona gave her to shut her up earlier, they had broken that barrier. Because this wasn't about anything other than making a baby, but she craved it. Wanted Arizona's lips on hers, wanted to claim the blonde that way.

Arizona's thrusting slowed just a bit, her strokes becoming harder, but deep and long as she moved her face to look at Callie, "Are you sure?" And part of Callie was glad that they seemed to be on the same page, or at least she hoped they were.

Looking deep into the blue eyes, the blue eyes that were also responsible for Callie wanting the woman above her to be the biological parent to her child, Callie dragged her hands from where they were on Arizona's body to cup her cheeks. "Please," She whispered, rocking her hips to drag Arizona deeper into her.

The first brush of their lips sent Callie flying, her legs locking against Arizona who had stilled her thrusting, but continued to rock against her, her muscles spasming around the blonde's cock and their lips still working against each other. When she came down and her legs relaxed Arizona began her thrusting anew, her tongue invading Callie's mouth to the same rhythm as her cock and the fire was building quickly in Callie again.

"I'm gonna cum Calliope," Arizona husked directly into her mouth, never once breaking the kiss so it came out garbled.

Their hips rocked against each other only a few more times until Arizona came with a grunt and an erratic thrust, stilling herself deep inside Callie who came again, her muscles once against contracting wildly, milking Arizona's cock. The hot ropes of cum shooting into her almost relentlessly, and suddenly she was filled with purpose and potential as Arizona emptied herself into her womb.

*889*

four and a half weeks later

"This is your fault!" Callie moaned to her best friend.

Her breasts were tender, she'd been throwing up, and she was late. She'd never once missed a period in her life, and now… she was late.

"I told you to have sex with her, not fall in love with her," Addison said from somewhere between Callie's spread legs.

Four pregnancy tests and one frantic midnight call to Addison and here they were, both in pyjamas, well Addison in pyjamas, Callie had shed hers and was wearing the ugly pink gown of Addison's practice, at three in the morning so Addison could perform an ultrasound because Callie was late.

And her boobs were tender.

And because even the smell of pickles wafting down the street made her nauseous.

And because she'd had sex with Arizona and now she was late.

Which was entirely the point of having sex with Arizona. Not to say that she had fallen in love with the blonde, because she hadn't, she definitely did not love her that way. She loved that she was kind and caring and compassionate and gorgeous, and she loved how good Arizona was in bed, and she loved the sound of her laugh, and the way her eyes sparkled and her dimples popped, and she loved the way that Arizona's curly hair sparkled like the Miami sunset, but she wasn't in love with her. She just… loved her.

"It's like your heart is in your vagina for crying out loud. This will be cold and you'll feel a bit of pressure."

Suddenly the transducer was in her vagina, like her heart apparently, and both women's focus was on the screen of the ultrasound as Callie's uterus came into focus.

"Congratulations Cal, you're pregnant."

Okay, so maybe a little bit she was in love with Arizona Robbins.
