Rarity awoke to the bright morning sun in her face with a quiet groan, her head and body aching moderately despite the cloud-bed's electricity, with her lower belly feeling very full, and her lower body's fur and her muzzle feeling matted down with the dried remains of sticky fluid. More importantly, she felt something hard and fleshy still gently pulsing with a heartbeat inside her pussy, as well as a heavy warmth even deeper in her belly; a large pair of hooves surrounding her chest. Felt a large, furry chest pressing into her back. Then she remembered the previous night: she remembered the lovely stallion whom she'd talked to at the bar for hours then invited home when she was half-drunk, invited him to share her room...then bed. Then her body, which he was still currently occupying.

Rarity blushed lightly as she felt what was his semi-hard penis and rather prodigious load of semen deep inside of her, possibly even bigger since he'd probably cum inside of her again while they'd slept. Then she remembered that she'd been his first. She remembered how he'd ravaged her the previous night with that very thing, his sizable member spreading her open as he'd submitted to his primal instincts. She thought of how much of his cum he'd shot so deeply into her and still compacted into what must be her uterus by his cock's sheer length and the quantity he'd cum, his flare still spread wide inside of her, encouraged by her body's instinctive kneading. She could never be more thankful for contraception magic and that she wouldn't have to worry about having a foal by him from that lovely, warm creampie deep inside of her womb.

Rarity then carefully extricated herself from his hooves then let out a quiet, displeased moan as his still-flared cock was pulled out of her with some difficulty, trailing with it a small pulse of pleasure through her and a small stream of his and her cum drooling out of her and onto the mattress. She then wobbled her way to the bathroom, her legs still slightly shaky from just how rough she'd ridden him, and how hard he'd fucked her at her demand for that matter. She went into the shower, intent on cleaning their sticky cum from herself, her entire crotch and lower belly clumped with so much that the feeling was virtually making her gag.

As quickly as possible Rarity got into the steamy shower, letting out a pleased coo as the hot water washed over her still-sore body, making pleasant tingles roll through her. As she bathed, she thought about that stallion now resting in her bed, how handsome he was and what a personality he had. She, however, also thought of her dream to one day marry a noble stallion, to be deemed a title, perhaps a duchess or maybe even a princess, if only by title. To have foals of noble blood by him, and to live a life of riches and glamor like she'd always dreamed. One that simply could not be possible with a lowly budding DJ as her husband.

As she finished washing herself of the last night's emissions, Rarity stepped out of the shower and spent the next hour preparing herself for the world, applying makeup and curling her hair just right. As she stepped out of the bathroom, she felt her heart throb as she saw the stallion now uncovered with his hard dick still pressed into the mattress, making her nearly tempted to wake him up and go another round. Instead, she went over to the stationary desk and, reluctantly, picked up a quill in her magic:

[center]Dear Mystery Stallion,

I wanted to thank you for last night, but hope you can understand that I have other obligations to attend to now. Last night was wonderful and I will never forget it, or you. I'm heading back home now, but I do hope we can meet up again like this again in The Bass-Ment next time I'm in Canterlot. When you read this, also please be a dear and return the hotel key to the drop-box before you leave.

Rarity then kissed the letter where a signature would go with her red-lipstick-covered lips, leaving a distinct red kiss-mark on it. She walked up to the still-sleeping stallion who had showed her such a good time and kissed him softly on the cheek as well, with him stirring in his sleep as she did, her leaving him with the mark of her lips as well as placing the folded letter on the pillow she'd slept on. As she gathered her few things, including the silk strips she'd cut the sheet into last night and noted to pay for before she left the hotel, and quietly and packed them away, she gave one final look over her shoulder as she carried her bags in her magic, giving a quiet sigh as she felt her stomach twisting, like when she was doing something she would later regret.

Rarity thought of the hug they'd shared after they'd had sex, the cuddling they'd done all night. The kiss they'd shared. How close she'd felt to him all last evening and night. Regardless she had a business to run, and as such turned and stepped outside, leaving the stallion as she closed the door behind her.

Instantly, she regretted it.

Rarity headed down the hallway to where Coco was staying, wanting to say goodbye to her friend and thank her for making such a wonderful night out possible for her. When the knock went unanswered, Rarity became quite worried for her friend when she heard a muffled moan coming from inside the room. Fishing out the spare key for her hotel room that Coco had given her, Rarity let herself in. When she did, she was quickly assaulted by the earthy-musky scent of an Earth-pony mare in heat as well as the musk of a stallion, combined with that distinct scent of sweaty sex. As she'd opened the door, the moans became even louder, the passion in them now obvious. In the entryway of the roomwas a wide-brimmed green hat from her new Spring lineup. The hat that she had given to only one pony prior to its yet-to-be-announced release. Coco Pommel.

"C-Coco?" Rarity whispered more to herself than aloud, approaching towards the bedroom. She stopped herself when the loud, rhythmic creaking of a mattress became audible, the moans even more impassioned and joined by deeper ones that could only be a stallion's. As she looked to the wall she saw a shadow silhouette of a mare atop another pony on the wall outside the bedroom, backlit by the morning sun. She watched the mare shadow rising and lowering, with what was obviously a stallion's cock joining the shadows.

"Y-YES! PLEASE! C-CUM IN ME AGAIN, JUST LIKE L-LAST NIGHT! OH F-FUUUUCK, I CAN FEEL YOU F-FLARING S-SO DEEP INSIDE ME M-MOON! I-I NEED YOUR CUM! I'M SO...H-HOT INSIDE, C-COOL ME DOWN! YES, YES...YE-YEEEEESSSSSSS~!" Rarity heard Coco's voice crying out in a needing, desperate tone she'd never heard her use before, before then hearing the two mating ponies cry out together in what was clearly orgasmic bliss, watching the mare's silhouette dropping down fully on the stallion's and remaining planted while letting out a loud squeal of relief.

As she realized what she'd just witnessed, blushing and getting rather horny from walking in on what was very likely one of her best friends possibly, likely unintentionally, being bred and filled with a foal, Rarity was almost tempted to go in and join them. Refusing her sudden burst of desires, Rarity turned tail as she felt her own cum-filled nether growing moist again, leaving in a hurry with her tail between her legs to keep her drippings contained without saying goodbye.

After all, she could always write her a letter saying the same thing.

Hours later the stallion awoke, reaching a hoof over to hug the beautiful mare who was sharing his bed and to thank her again for the previous night. He'd planned to ask her to be his marefriend after that wonderful time and the closeness he felt for her, feeling a fondness for her that he'd never felt for another mare, but he'd fallen asleep. He could swear he loved her, this mystery mare who'd swooped him off his hooves and been his first time.

As he heard the distinct crinkle of parchment and felt it instead of a mare beside him, he opened his eyes to see that the bed was empty save for him, seeing the mare's bags and clothes gone as well. As he found a closed note on the pillow beside him instead of the mare he felt so much fondness for the previous night, he picked it up and opened it, feeling his heart wretch, tears coming to his eyes as he read it.

"I will find you again my love...I promise you." he whispered aloud, letting the letter fall to the bed before galloping outside, hoping he could find her before she left Canterlot.

Rarity stepped off the train in Ponyville, heading towards her Boutique to open it and start the day. As she cantered, realizing she was running late, she found all she could think about is the stallion she'd shared herself with so fully the previous night; how handsome he was, how he'd made her laugh and been so focused on pleasing her when they'd had sex. How she'd been his first. How he'd never forget her; how she'd never forget him.

As Rarity slowed to a walk, she felt tears forming in her eyes, her mascara starting to streak down her white cheeks as they were loosed, her stopping as she felt her own heart wretch in her chest, only then realizing just what a mistake she'd made. "By the Sun what have I done..." she whispered, standing there crying as she considered the wonderful stallion who could have possibly been hers.

~ ~ ~

Rarity sat in the Ponyville Hospital doctor's office, waiting her turn to be seen. It was about seven weeks after she'd spent that wonderful night with the mystery DJ stallion, had sex with him and had him finish within her, then left him with but a note and a kiss on the cheek. She'd been experiencing a week of severe morning heartburn and powerful stomachaches and cramps, with it sometimes evolving to nausea and vomiting, as well as an increased appetite and odd cravings – mostly for chocolate-covered radishes, oddly enough.

Doctor Stable stepped in with a smile, Rarity returning it even as she held her aching stomach. "Hm...what seems to be the problem Miss Rarity?" the doctor asked, flipping through her charts with his magic, "...let's see, morning sickness, increased appetite, steady weight gain. Ah yes, I have a good idea just what's causing this, but first let's do the full physical you requested."

"Oh please doctor, this simply cannot continue! I cannot run my boutique with such horrid issues as these...and I certainly cannot model my designs if I'm getting...fat..." Rarity said dramatically, her hoof's cannon on her forehead, striking quite the pose as she lay on her back.

Stable simply nodded passively at her drama, then got to work. He performed a simple physical, noting a particular swelling and firmness to the touch in her lower belly, collected a cup of urine from Rarity, then went off to the lab and left her alone in the examination room again.

Within ten minutes Stable returned, wearing a very bright smile. "So, whatever is wrong with me Doctor? Am I alright? Am I going to die?! Do I have some horrid, rare disease with no cure?!" Rarity asked, acting as though she were on her deathbed despite the practitioner's cheery disposition.

"Well, no. Quite the opposite in fact. As I suspected, you're a perfectly healthy young mare in prime condition, having top marks in every category according to the physical I performed." Doc started, his smile widening a bit. "In addition to the physical, and according to the symptoms reported by you, I took the liberty of collecting a sample of urine from you to perform a standard pregnancy test as well. Miss Rarity, it came back positive through all three checks I put it through. Congratulations, you're about seven to eight weeks pregnant!" Stable said, showing her the positive pregnancy test results and also giving a big, genuine smile; he always loved delivering this kind of news, even if the mothers sometimes didn't like receiving it.

This was one such case. "H-HOW?! HOW AM I PREGNANT?!" Rarity exclaimed, asking herself more than the doctor, "I...I ALWAYS USE PROTECTION! MAGICAL PROTECTION!" Rarity stopped, sobbing once. "H-how am I going to have royal foals with a prince now? How am I going to have my happily ever after without my prince..."

The doctor took a step back at the yelling, wincing and his ears folding back at the volume and tone of her voice. "M-Miss I assure you, getting pregnant during an estrus season unexpectedly is perfectly normal and common," Stable assured her, putting a hoof on her shoulder, "Sometimes estrus just sneaks up on a mare and she mistakes the symptoms of a minor estrus as simply feeling frisky. Since you're surprised, I suspect you didn't know you were ovulating at the time of intercourse?" he asked, seeing Rarity lightly trembling now, visibly upset.

"N-no, this...I didn't want this at all. I'm...not ready for a foal!" Rarity exclaimed, knowing her whole career and very life would be changed by this. "S-so I'm really pregnant..." Rarity muttered, the doctor nodding as she rubbed over her lower belly, her foal-filled lower belly; "...but...how? I used the simple 'Starswirl Anti-Foal' spell on myself before...and I wasn't even in my estrus week when...it happened."

"Well Rarity, were you perhaps inebriated at the time of casting? Tired? Even a little bit distracted? That particular spell is the fairly complex original version of the common contraception spell used today and requires full focus to get all of the steps right, unlike its other easier, refined version. One mistake, and it won't work. This is why we tell even the most experienced unicorns to use physical condoms as well, or a second foal-preventing spell cast by another unicorn, so that way if one fails, there's less of a chance of an unplanned pregnancy." Doc explained, with it dawning on Rarity that she was pretty out of it when she'd tried to cast the spell...realizing now that it was the one she'd learned from Twilight during some inane conversation instead of her usual contraceptive spell; casting it when she horny and apparently in estrus, enamored, and drunk...not in her right mind.

"Also," the doctor continued, "regarding you not feeling 'in season' at the time of your foal's conception...perhaps you were in what we doctors call a 'silent heat', meaning that except for a mare desiring sex strongly and an overwhelming desire to have a stallion ejaculate within them, there are no telling scents or too-obvious behaviors from her. Matter of fact, I've gotten a couple of other cases just recently in which a mare came in here with the same symptoms as you, and her heat had come earlier this year than she'd expected given the sun being closer to the planet this year, causing more UV ray which trigger estrus and ovulation....more than a few, now that I think of it." the doctor said, his hooftip tapping his chin as he pondered, before continuing. "But really, silent heats are actually not too uncommon themselves."

"S-so, what now?" Rarity asked, looking on the verge of tears. In a moment, her whole life had shifted course. A foal. She was going to have a child in about more nine months and she was nowhere near prepared for it. She didn't even know the name of its sire! She would have to take time off of her job for trips to the hospital both for checkups and the birth, would not be able to model her own designs while carrying...not to mention all the time she'd need to dedicate to the foal for the rest of her life...

"Well, since you didn't know you were pregnant until now, I should probably first ask you if you intend to keep it." the doctor asked, with Rarity sensing he was asking her if she wanted to self-abort* it.

"N-no, no...I can't do that...to my child." Rarity said instantly, knowing that despite her being able to end this pregnancy any time she wanted to by herself, she knew she couldn't live with herself if she ended an innocent life for her own selfish reasons. The life of her own child.

"Right, great to know. Now that I know you're going to go full-term, I'm going to write you a prescription for prenatal vitamins to keep you and the foal healthy since you're keeping it. The reason for the severe morning sickness, in addition to the natural hormonal changes involved with a pregnancy, is likely because you probably haven't adapted your diet to properly reflect that you're carrying now, which may have been aggravating your stomach more. The odd cravings are also related to the hormonal changes and your body's deficiencies because of the foal's needs." Rarity nodded, knowing she ate a lot of things that probably weren't the best for an upset stomach, let alone a carrying mare. "I'm also prescribing a pregnancy-safe anti-nausea medicine to help with the morning sickness, and will also give you a pamphlet of the proper diet for a pregnant mare. Also, stress strongly contributes to pregnancy symptoms, so try to keep calm as much as possible. No more freak-outs or drama like earlier either, for the sake of your child and yourself."

Rarity simply nodded, still shell-shocked this was actually happening right now.

"Oh and off the record, since this wasn't a planned studding, I'd like to suggest you inform the most likely sire - or sires, if there are multiple, again not uncommon - that you are carrying his foal even if it was a one-time thing...n-not that I'm saying that it was, but it's not at all unusual. As a proud father of two, I know I'd be devastated if I found out years later I had a foal and never got to see them being born or growing up. Of course this is your choice, but give it some thought."

"I...um...I don't even know the sire's name..." Rarity said despondently, remembering back to the only possible sire for her foal. She'd not had sex since the mystery stallion had taken her that night, her having no desire to even look at another stallion in a sexual way. She was confused at first, not knowing why she didn't have her usual libido during mating season when all the mares, including her best friends whom she sometimes had 'heat-buddy relations' with during their generally-shared estruses, went into heat and the stallions into rut, but this answered everything. Why she couldn't get her thoughts off of that stallion who had given her a wonderful night and had stolen her heart, and why her heat hadn't come this month. She loved that young, handsome DJ, the father to her child, and planned to find him again. "...but I plan to rectify that."

"Also, Rarity? A little personal advice off the record: don't think that you need a prince to get your happily ever after. My wife isn't an official princess, but I'd never take one instead of her. She's my little princess though," Stable said with a wink, "Sometimes we make our own princes or princesses, our own happy endings, instead of them coming and swooping us off our hooves. Now though, off that tangent, let me get you those prescriptions written, and you can be on your way."
