Windy Wanders while Bow Bangs

For several years now, on her birthday, Granny Smith has thrown an anonymous sex party at the Sweet Apple Acres barn. The party is particularly specific: before the party begins, each attendee must submit a single strand of their mane to Granny Smith, Pinkie Pie, or Twilight Sparkle, who then log each pony in attendance, and give all of the strands to Zecora for adding into three massive brewing cauldrons - one for stallions, one for mares, and one for ponies who don't mind a bit of gender-swapping hijinx.

When the potions are complete, each pony is blindfolded and given a small flask of the liquid to drink from their respective batch, after which they are led to a seat to wait for the party to begin. At roughly 6 PM, a unicorn - usually Twilight Sparkle, who is often a participant herself - casts a catalyst spell over the room that activates the potions, magically swapping every pony who imbibed the potion with another pony who also drank from the same batch.

The magic fades after eight hours, and at roughly 2 AM, the ponies will find themselves back in their real bodies. This often ends with ponies waking in bed the next morning next to their unmasked lover from the night before, learning their true identity in the process, and several ponies have found their soulmate through this ceremony.

But not everypony is always so thrilled with the results.

"Rainbow?!" Bow Hothoof stood at the door to his daughter's Ponyville cloudhouse, shouting her name. "She's probably still asleep," he remarked to his wife.

"It's your parents, dear!" Windy Whistles called out, knocking on the door a second time. "We're coming in!"

Barging in uninvited was a habit of theirs. One that Rainbow herself had mastered. Now that the relationship between parents and child had been repaired, it was fairly common for Rainbow's parents to visit without any prior announcement. In absence of Rainbow welcoming them inside, Bow pushed open the door that Rainbow always carelessly left unlocked.

As cloudhouses often were, thanks to the ease of maintenance, the entire place was in pristine condition - debris could just be swept off of the cloud-proofed carpets and furnishings, leading all unwanted detritus to be blow off into the wind below, and a constant breeziness from the unsealed walls always kept the place smelling fresh.

"Rainbow?" Windy called out, walking back toward the living room.

Feeling peckish, Bow opened the refrigerator to see if there was anything worth snacking on as Windy wandered the rest of the house. Predictably, Rainbow had a lot of leftover food inside - some of it already long gone bad. A bowl of unfinished salad - two days old, according to the date Rainbow had written on the plastic wrap - called out to his appetite. If he didn't eat it, Rainbow would probably just let it go to waste, like the rest of the fridge.

He sat down at the table and began digging into the meal while Windy's voice continued to float on the air. No signs of Rainbow. A flier on the table caught his eye - one with a couple of ponies engaging in some steamy makeout. Hardly the kind of content Rainbow would have been into, surely?

Wiping his mouth with a hoof, he pulled the flier closer to read it.

"What the heck is a sex yoke?" Bow wondered aloud.

Windy had already given up on finding Rainbow Dash and returned to the kitchen. She scanned the flier quickly. "To be yoked together," she said, nodding. "One of those new slang terms the younger generation has started using, I think, but the roots go back to when ponies used to drive the cows to pull wagons." She shook her head. "I'm pretty sure they're only using that term for the acronym."

Bow stared at the flier a moment longer, and then burst out laughing. "Well, Windy, what do you think? Is Rainbow there?"

"It does sound like something she'd do. And it is Sunday... It's been a while since our swinger days, but I think I could get another round in, if you're down for some fun."

Bow leaned down and kissed her on the lips, then pulled away. "That's what I've always loved about you." He looked down at the flyer. "It could be fun, but it does say not to be late. It's already 6:00."

"Oh, who cares?" Windy rolled her eyes. "Every party flier says not to be late."

There was certainly some kind of party going on as Bow and Windy descended upon Sweet Apple Acres. Loud, thumping music was coming from a large set of speakers outside the barn, and ponies of both genders were bumping, grinding, or otherwise moving to the rhythm.

It was rude to simply cannonball into a party, so Windy and Bow landed a short distance away and walked their way in. They decided to split up and enjoy themselves separately, and within just a few moments, Thunderlane trotted right up to Windy. Bow smiled at the thought of his wife getting railed by a Wonderbolt. She'd be having a wonderful night.

Meanwhile, Bow continued to explore the premises. There was a giant red barn in the center of the festivities, after all. He peered in through the doorway to see a debaucherous celebration the likes of which he hadn't seen since college. A veritable orgy of mares and stallions having sex in a semi-public fashion!

Almost immediately, a very drunken earth pony mare grabbed him by the neck. "Hiya, handsome," she breathed, the strong stench of alcohol causing him to wonder if second-hand intoxication was a real thing. He had to admit, apart from her drunken demeanor, this mare was smoking hot. Her purple coat and mulberry mane, and berry-themed cutie mark got him thinking about the fruits of passion almost immediately. "Would you like to play?"

He couldn't help but notice her tail was already flagged and cum-stained. He'd never told Windy, but his favorite kink was to be the one to claim a mare after she'd already been taken. Some called it sloppy seconds, but to Bow, it was a matter of pride: a mare that was already happy to have been thoroughly fucked, and yet she wants more because the first wasn't enough of a stallion for her. It was empowering.

The mare had definitely noticed, too, as his cock had begun to descend from its sheathe immediately. "That's what I like to see," she purred. "Shall we find a private place and take care of that for you? Or do you want to do it right here?"

"Uh," Bow hesitated. Though he’d attended such events before, he wasn't big into overly public displays - these kinds of parties were great, but there was pretty much always a private room somewhere that could be used. "Can we find a private space?"

The mare beamed, and then turned around, her tail wafting the stench of sex right across his face. His cock went rigid, immediately. She was definitely fertile and needy. "Follow me, big guy," she said, staggering in a not-so-straight line toward a wooden door that appeared to be... an outhouse or something? She pushed the door open and gestured for him to follow.

Bow balked only for a moment as her glistening, cum-drooling slit called out to his baser instincts. He stepped into the room behind her and closed the door. To his relief, the room wasn't an outhouse - which, in hindsight, made sense, because it was inside the barn still.

"Come on, Big Boy," she said, spreading her legs in the classic head-down, ass-up, flagged-tail position. "Don't leave me waiting."

Bow didn't need to be asked twice. He reared up and immediately thrust himself into her warm, wet depths. She hissed in satisfaction as he hilted himself, and then he immediately began thrusting into her with abandon.

Her pussy clamped down in orgasmic convulsions almost immediately, and in that state it didn't take long for him to reach his peak as he fired off inside of her shortly after. He bit down on the nape of her neck as he unloaded a copious amount of his jizz into the mare, and she collapsed to the ground as her orgasm passed, panting heavily.

"Well," she breathed. "That body's a quick shot. Sorry you got stuck with that."

"Nonsense, that was incredible, miss... uh... what's your name?"

The mare shook her head and then her mouth opened wide. "If you want to know who I am..." she yawned. "You're going to have to take me to a hotel and..." she yawned again, laying her head down on a pile of straw in the corner. "Wow, this body is really drunk. I think I'm gonna pass out."

Bow frowned. "You don't have to drink if you don't want to."

She giggled. "No, it was drunk when I got swapped. I'm... pretty sure she's always drunk."

"Huh?"

Her eyes drifted closed. "The body swap, remember?" she mumbled. "The reason everything here is anonymous?"

"Oh, right," Bow agreed. Body swap? Is that how they retained anonymity at this party? Wow... that was hot. "I get it."

That must be why they weren't supposed to be late. Which means he couldn't let on that he hadn't been swapped. That was fine; he could do that.

"Thanks for—" Bow started - but the mare was already snoring softly. "Good night, miss," he excused himself and backed through the door.

Fortunately for himself, he wasn't a one-shot-thot. In a closed space like the barn, with the scent of mares in heat sent his body into overdrive, and it was already hard at work putting another load in the chamber - he just needed to find another mare to fire it into. He smiled at himself, remembering the flier’s bold proclamations.

Pregnancy wards were the best, and he intended to make the most of it. But first, he needed to let Windy know about the rule.

On any other night, Rainbow Dash would never wear her mane so immaculately styled. Fancy mane styling wasn't the way she did things, but tonight, seeing those purple curls bounce in her peripheral vision as she slowly descended the staircase made her smile. Not because she liked how it looked, of course, but because of what it attracted: stallions.

The pleasant, but unsatisfied soreness in her nether region - courtesy of somepony who currently looked like Davenport, the proprietor of Quills and Sofas - reminded her that she wouldn't be the one feeling it in the morning, either. She spoke a silent apology to Rarity in her head, and a quiet hope that Rarity was also having a great time tonight.

Her partner had, infuriatingly, passed out within moments of 'finishing' during their tryst - rather unsatisfying for Rainbow, as he'd left her pleasure incomplete right as she was approaching her peak. Rainbow couldn't complain too much, as she'd taken a stallion's body for a spin last year for the first time and ended up doing the same to somepony who looked like Octavia - who was also less than thrilled. She'd never known how bad it could be for stallions when they finish, but surely somepony around would be fit to finish the job tonight.

Quietly, Rainbow returned her room key to the Mâché Mansion's concierge and made her way to the front door. Her tail flicked and twitched, this year's late-spring estrus hitting Rarity's needy body quite badly. She'd be okay with a mare to wrap up the night - the mare at the concierge desk was pretty cute. But she really needed another dick. Hopefully, she'd find another stallion to sate her lusts before the potion wore off.

Fortunately, there was no pregnancy risk with these parties. The magic involved in the body swap made sure all of the stallions were rendered infertile for the duration, which was a blessing for those mares laden with the burdens of a raging heat - a day or two of relief from the physical neediness at the height of breeding season made it much more bearable.

Rainbow stepped out onto Pear Street. Several notable Ponyville venues were constructed from bizarre materials, and the Mâché Mansion was no exception. Constructed entirely of papier-mâché, it was a rather ugly building that stood out like a sore thumb among the others here - and was well-known for its 'clientele'. And not in a good way. Any other night, and Rainbow wouldn't have set foot in the place. Nor would her host. Rainbow beat a hasty retreat, hoping to salvage some semblance of Rarity's reputation.

She'd chosen the Mansion for her little liaison because it was one of the closest venues to Sweet Apple Acres, which worked wonders for Rarity's rather dainty hooves. Being trapped in a unicorn's body meant no flying for the night, and Rainbow had only mastered the barest of levitation spells, aided largely by Rarity's instinctive muscle memory and the faint memory of that other time a couple years ago - the last time Rainbow had found herself as a unicorn. There was no chance she'd be able to teleport, even if she tried.

End result? Walking. Rainbow hated walking - the sky was her world. Fortunately, her legs were unhindered. While Rarity's mane was never ignored, Rarity refused to dress up for this particular event after one of her favorite dresses was destroyed by a careless pony who had her body the first time she participated. It had been bad. Rainbow wasn't one to kink shame, but Rarity was.

The party had developed some unspoken rules over the years. It was expected that anypony wanting to go for a 'round two' would come back to the farm and pair off again, but the number of stallions would fade off much quicker than the mares, thanks to refractory periods and stallions generally wearing out faster. This made it a great option for a bisexual mare like Rainbow - if the stallions were out of stock, there would be plenty left to browse.

Sweet Apple Acres' barn came into view fairly swiftly. Out in front was a spread of tables and food that had been fit for an Apple family reunion before the first round of hungry ponies had descended upon it. Off to one side was a dance floor, dotted with a few ponies swaying to the beat of music Rainbow didn't care for. And on the other side, a bar where Granny Smith served up the signature Apple Family Cider on tap - alcoholic, of course, to lower the inhibitions even further.

About a dozen ponies - mostly mares - were seated at various tables. Some were eating, most were chatting, and all of the stallions present seemed to have mares hanging on them already.

Rainbow frowned as she approached, internally weighing if she wanted to wait and see what stallions might arrive yet, or if she should just sate her urges quickly and try to chat up one of the mares. She had an advantage in the stallion department, as there was no shortage of stallions interested in taking Rarity's beautiful body for a test run, but Rainbow herself was also notoriously impatient.

But before she could reach the veritable smorgasbord of sexual desserts in front of her, a quick flash of rainbow color caught her eye. A rainbow that was very familiar. Somepony was in her body nearby. And a morbid curiosity set in: what was he or she doing with it? Would she be walking funny in the morning, too?

Rainbow initially thought to try and be stealthy as she snuck around the back side of the barn to spy, but almost immediately gave up that idea as Rarity's near-white coat stood out against absolutely everything, even in the dimming light. She opted instead to just walk past nonchalantly and pretend like she was going somewhere. The sounds of sex grew more and more audible as she approached, the obvious sound of her own voice crying in ecstasy luring her further forward as stray strands of rainbow-patterned tail sticking out just past the end of the barn rocked back and forth, attached to her body just out of view.

Rainbow paused. Had somepony cropped her tail?! That was a ridiculous violation of her autonomy!

But... no. That didn't make any sense, Rainbow realized. The tail moving in front of her was clearly moving as a stallion would. It wasn't her tail. And three steps later, she stopped and stared as her father's cutie mark came into view.

She was watching a pony in her father's body wreck some poor mare.

And yet, the sound of her own voice haunted her.

A few more steps forward confirmed her suspicions. The body of her father, Bow Hothoof, was balls-deep in her own cunt, hammering away with abandon.

Thousands of thoughts flooded Rainbow's mind all at once.

Why are you staring at your dad's dick?

Why are you staring at your own cunt getting plowed?

Why is my dad here?

I wonder if that feels as great as it sounds?

Sisters Above, that dick is huge.

Wow, that's a lot of squirting. That must feel amazing.

Why am I watching my dad fuck myself?

She stared in silent awe as her father's cock thrust in and out of her own abused pussy, harder, faster, and stronger than anything she'd ever seen or felt personally.

Meanwhile, whoever was in her body was having the time of her life, thrusting back against him erratically, moaning for more, gushing copious femmecum all over her father's legs, and begging to be filled with his seed. Rainbow had always been a squirter, and there was evidence of it everywhere.

It was wrong for this to happen. It was wrong to be watching this. But it was... really... really hot.

Her father's head turned, and it was obvious she'd been caught staring. He simply smiled and winked, mouthing something to her that she couldn't ascertain with his violent thrusting motions. If she'd been horny before, watching this debaucherous liaison had thrown her hormones up to heights the Wonderbolts only wished they could reach.

"Sorry!" Rainbow squeaked out in Rarity's dulcet tones, turning tail and cantering away as quickly as she could. Her heart thundered in her chest, and she could feel her marehood absolutely dripping with desire. Rainbow beelined straight for Granny Smith's bar.

She really needed a stiff dick. Or drink.

... Okay, both. But one step at a time.

"Four ciders, please," Rainbow begged.

Granny Smith's old, frail body moved slowly as she reached out for a mug and began filling it. "Four ciders, dear? Let's start with one, and see where the evening takes you, hm? You young'uns always think you can drink more'n ya can."

"Yeah, whatever," Rainbow repeated, sounding very much not like Rarity, in spite of her voice. "Just gimme a drink. And hurry."

"Hmmm..." Granny said, slowly. "What's the rush? The night is still relatively as young, though perhaps not as young as a lovely filly like yourself."

"I made the mistake of spying on somepony and I saw something I wish I hadn't."

"Oh?" the old mare replied, setting Rainbow's drink on the bar. Rainbow drained the mug in a single, massive swill, setting the mug back on the table. That confounded itchiness in her nethers would only be compounded by the presence of alcohol, but she would have to make due.

"Pray tell, what did you see?" Granny pressed, filling a second mug.

"Just an experience I don’t want to remember in the morning," Rainbow groused, already working on the second drink. "And I'm hoping if I drink enough, I won't."

Granny hummed thoughtfully. "From the way I've seen you trotting around for the last few minutes, I'd wager that you've already had an experience that will leave Rarity walking funny for a few days."

"No offense, Granny, I love your parties, but you're like, the last pony I want to talk about my sex life with."

"Oh, I hear all the details from everypony else anyway, but if you're not comfortable with it, we don't have to discuss it. I am curious, though, who you saw? How big was he? I still have an eye for a good stallion, y'know. Not that my body can keep up, mind you, but the eye candy sure is nice..."

Rainbow sighed in defeat. This old bat never would let anything drop, and given her growing senility, Rainbow didn't want Rarity to be plagued with the questions later. "It was m—" my dad? Don't say dad. "Uhh... Bow Hothoof’s dick."

Granny Smith's hooves dropped to the table. "Bow Hothoof?" she repeated in her dry, cracked voice. "Bow Hothoof?" Granny ducked under the table, suddenly much more animated than Rainbow had seen since the Flim Flam Brothers had sold her on that stupid tonic. "Oh, no, no, no," Granny muttered, slowly tottering her way across the dining area. Rainbow skipped forward quickly, trying to catch up to Granny's sudden departure. "Where d'ya see them, miss?" Granny inquired. "I need to stop 'im."

"Stop what?" Rainbow wondered aloud.

"Oh, don't you worry 'bout that none, miss. I'll deal with that. But I need to know where."

"Uh... alright," Rainbow gestured down the side of the barn. "They're just over there, around the corner of the barn."

"Thank ya kindly," Granny said, still moving far faster than Rainbow had seen in years. She struggled to keep up on Rarity’s less-than-athletic legs, and was still levitating her third drink. The alcohol was starting to have an impact, too. Everything was confusing. This was happening so fast, Rainbow wasn't even sure what was going on anymore.

Just around the corner, Granny stopped dead in her tracks, staring wide-eyed at what was going on. Rainbow came up behind her and gaped - her father was still balls deep inside her own pussy, cum dripping on the ground beneath them, and he was still pounding away.

"Goddess, yes, Big Blue, fill me up more," came the sound of her own voice.

Granny grabbed Rainbow by the mane and dragged her back around the side of the barn. "Darn it!" she muttered under her breath, seemingly losing her accent entirely. "I can't stop them. I can't."

"What?" Rainbow asked, confused. "Why not?"

"This is very bad right now," Granny croaked out. "Please talk to Princess Twilight first thing tomorrow; tell her everything that just happened. She'll know what to do."

"Uh... why can't I talk to her now?" Rainbow asked, still not understanding what the issue was.

Granny gestured around her. "Because nopony knows who she even is right now. Now, I need you to promise me something, miss. Promise me that you'll go see Twilight tomorrow!" Granny seemed to be angry, like a subdued rage boiled just under the surface of that request.

"O-okay," Rainbow said, stepping back under the intensity of Granny's tone.

Rainbow Returns with Cloudsdale Confessions

The night wasn't a total bust for Rainbow Dash.

After a few more drinks, she was pretty trashed and ended up settling for a lesbian partner after all; an extremely talented one - in the guise of Mayor Mare, of all ponies - and who was quite open about her desire to dyke out with Rarity. The 'Mayor' had insisted that she wanted to remain anonymous right before she ran off, leaving Rainbow alone in a wet, sticky bed of their shared orgasmic experience.

The bed had soon turned cold and Rainbow had given up on sleeping in the mess. She returned her key to the concierge at Dusty's Den and slowly trotted home, a little noodly on her feet between the alcohol and the orgasms, but mostly satisfied.

Rainbow had just experienced the heights of ecstasy several times, with her only real complaint being the utter lack of dick that her body was craving. A lack that was absolutely killing her right now, though it was no longer her primary concern. After ten minutes of staggered walking, she stared up at her cloudhouse, her wingless sides useless. It would still be a couple hours before the spell wore off, and she was exhausted.

With a sigh of resignation, she stumbled for fifteen more minutes over to the Friendship Castle. She would be going there in the morning anyway, and at least the guest rooms were comfortable.

No one greeted her as she arrived - no sign of life anywhere in the castle. Rainbow idly wondered if there was any security at all tonight, but as her hooves clipped delicately across the crystal floors of the castle, the soft rhythm drove her further and further into the land of dreams.

She found the first of many guest rooms, and her eyes drifted closed nearly the moment that her head hit the pillow. The alcohol would certainly–

GIANT

Rainbow's eyes snapped open and she shook her head. After a few moments, she closed her eyes again.

BLUE

That need in her loins flared up again. Rarity would be suffering tomorrow after Rainbow had teased her body so much and not gotten sufficient seeding, that was for sure. Rainbow squeezed her eyes closed, trying desperately to ignore those desires.

THROBBING

She rolled onto her side, tossing and turning to find a more comfortable position to lay in. She closed her eyes.

DICK

"GAH!" Rainbow sat bolt upright and screamed to the air around her. "STUPID, DAD! Mom's going to bucking kill you! Why were you even there?!"

Rainbow hopped out of the bed. She needed to distract herself with something - anything! - to rid herself of this stupid vision seared into her mind. She stepped out into the hallway and started trotting toward the library - the only place she could imagine finding a distraction at this hour. After all, an action-packed (and more importantly, chaste) Daring Do book would surely do the trick.

Curled up in a chair in the library, with the book in her magic, Rainbow passed the time in misery, drunkenly fumbling with the pages, until finally she felt a shifting disorientation: Her body was back, and the sudden sobriety brought the world into sharp focus. The burning need to be seeded by a stallion was gone - or at least, heavily reduced - replaced instead by a raw ache of intense, passionate lovemaking. The book clattered to the floor, no longer supported by her spell.

This ache was far more intense than any post-coital soreness she'd ever experienced. Was this what was left of her father's debauchery? The thought of her father's cock no longer commanded her breeding instincts, but the memory now matched the feeling in her groin. Still, she tried to ignore the pain as she flailed about and retrieved the book from the floor. After a few minutes, she was engrossed in the book again, and she continued reading, despite the ache, until she slowly, unknowingly, fell asleep in the middle of a page.

"STARLIGHT!"

Rainbow startled awake to the sound of galloping hooves and Twilight hollering down the hallway. She hadn't had nearly enough sleep yet, but with that cacophony in the hallway, she wasn't going to be able to ignore it enough to return to slumber. And an actual bed would be nice to move to.

She stood from the chair and stretched out, teeth clenched from an excruciating pain. She knew it was from the abuse her body had been put through the night before. From the dock of her tail to her hind legs, every nerve cried out — but the accursed itch of lust in her nethers, for the first time in several days, was actually bearable. Not absent entirely, but significantly improved. Granny's parties were perfect for subduing that particular urge, and this year's seemed to be remarkably effective.

Her morning stretch was done just in time to see Twilight fly past the open library door. "Twilight, wait! Slow down!" came Spike's voice right after, his clawed feet clacking much more softly as he ran past the door. Rainbow couldn't help but notice that both of his arms were full of papers.

Curious about the commotion, Rainbow trotted—nope, it hurt to walk— she hovered to the doorway and peered up and down the hall. Twilight and Spike were already gone and out of sight, but a trail of dropped pages from Spike's armful of notes littered the hallway, providing her with a trail to follow. Rainbow flapped her wings slowly and floated down the hallway, following their lead. Eventually, the trail led her through several turns, where Spike's tail protruded out from Starlight's bedroom.

"—weren't at the party last night?" she heard Twilight's voice echo out of the room as she approached.

"You don't need to yell," Starlight whined, sitting upright in her bed and rubbing the sleep from her eyes. "And, no. After last year's... debacle, I decided to sit this one out." Starlight rested her head back on her pillow.

"You were supposed to cast the perimeter spell, Starlight! You can't just not show up without telling me!"

"It's not like it's ever helped before,” Starlight argued. “Not a single pony has ever tried to get in. Besides, what's the worst thing that could happen? "

"Oh, I don't know, Starlight," Twilight said sarcastically. "Maybe a stallion will walk in and..." She stopped, turning a redder shade.

Starlight giggled. "That's kinda hot, don't you think?"

"Girls, Rainbow is here," Spike said.

Starlight sat bolt upright in her bed. Twilight turned and immediately tried to force a smile. "Rainbow Dash," she greeted nervously.

"Hey, what's going on?" Rainbow replied.

"Oh, uh... nothing at all! Why are you here so early in the morning? Don't you usually sleep in after a party?"

"Was ground-bound last night. Slept in the library with a good book,” Rainbow flicked a hoof dismissively. “I'm sure you know the drill. Anyway, I need to talk to you."

"Well, as you can see, I'm a little busy right now with something very important, but we can meet for lunch together if you'd like."

"But you just said it was nothing." Rainbow insisted, hovering just inside the doorway. "And I'm not moving until we talk."

"But—"

"Uh, Twilight?" Starlight frowned. "Why don't you just tell me what's going on, and let Rainbow listen in. And then we can all talk over breakfast. You know she's nosy and she's going to ask anyway." Rainbow nodded to herself a silent affirmation. "It'll save you the explanation later."

"Hey!" Rainbow protested weakly, even though she knew it was true.

Twilight stomped her hoof. "Fine. But you need to get out of bed. We have work to do."

"Oh, joy of joys," Starlight groused, tossing the covers off of herself.

"Okay, so, I've been informed by a certain organizer" - Twilight made air quotes with her wingtips - "that the perimeter was breached last night. Thank you for that."

Starlight slumped back onto the bed buried her face in her pillow, holding it down with her hooves. "Nope," she yelled into the pillow. "Too early for this kind of drama!"

Twilight's horn flared as she yanked the pillow away and tossed it behind her - which happened to be directly at Rainbow. Rainbow deftly veered to the side and the pillow sailed into the hall, scattering some of Twilight's notes still laying on the ground.

Spike watched the pillow sail past Rainbow. "Oh, hey, I dropped some," he piped up, going out into the hallway to gather the scattered pages.

"This isn't the time for that, Starlight! One of the stallions wasn't at the imbibement, and his spermatozoa weren't sterilized. And I've heard reports that he may have had at least three partners! We can't have those poor mares getting pregnant from acts they didn't consent to!"

"...Oh, horseapples," Starlight cursed, rolling out of bed. "That's bad. Do we know for sure how many?"

The gears in Rainbow's head began to grind. Granny's upset. The way she'd been desperate to track down the stallion... that was...

...having sex with...

...it was her dad?

"P-p-p...pre...p-p..." Dash stuttered.

Twilight turned to Rainbow with concern as Rainbow continued to fail at basic communication. Starlight put a hoof on Rainbow's shoulder.

"Are you okay?" Starlight asked. Rainbow continued to stutter.

"Wait," Twilight interrupted, her eyes widening in recognition. "Did you need to talk to me because Granny recommended it to you?"

Rainbow couldn't speak, her mouth was dry like cotton and she was breaking into a cold sweat. She simply nodded.

"It's okay, you don't need to worry!" Twilight said quickly. "The stallion who got in was your dad, I'm sure he didn't..."

"No!" Rainbow finally blurted, shaking her head violently. "No! No!"

Starlight and Twilight simply stared as dawning realizations came over both of them.

"You purposely had sex with your dad?" Twilight blurted, horrified.

"N-n-n-n-n-n-n—"

"You saw your dad having sex with somepony else... in your body?" Starlight guessed.

Rainbow stopped trying to speak, her head repeatedly nodding in affirmation.

"Oh, Luna's teats," Twilight cursed. "Rainbow, you need to get to Ponyville General, right now! Get a pregnancy test so we can figure out what - if anything - needs to be done."

Rainbow began shaking uncontrollably. Her dad might have knocked her up?!

"Come on, Starlight!" Twilight said, wrapping her wing around Starlight. "We need to get a new spell working right away."

In a flash of light, both other mares were gone, leaving Rainbow almost completely alone.

"Annnnnd, they left me again," Spike grumbled, one foot inside the door, arms once again full of scattered notes. “Rainbow, are you okay? You don’t look too good.”

Rainbow simply nodded dumbly.

"You look like you need more sleep,” Spike advised her. “Always helps me out when I’m stressed. Tell Twilight her notes are in her study. Rarity asked me to come help out at the boutique because she’s badly hungover.” Spike disappeared into the hallway again.

Rainbow's memory flashed back to seeing her body being rutted by the stallion looking like her father. And how much she had been turned on by that, despite her better judgment.

But now she knew that he didn't just look like her father. He was her father. And now she might be a mother... to his foal.

The throbbing pain in her groin came rushing back. Unless that was somehow the work of another stallion, there was no way a rutting like that wouldn't have left her with...

That was way too much for Rainbow to process right now. Spike was right. She needed to sleep on this one. And conveniently, there was a bed right in front of her. Rainbow slid under Starlight’s covers and laid her head down.

She tossed and turned, trying to get comfortable, but the lack of a pillow made it impossible. The discarded pillow was still in the hallway, stopped against the far wall. Rainbow grumpily rolled out of the bed and went to retrieve it. As the pillow came off the ground, it kicked up a piece of paper that had been wedged beneath it - one of Twilight's notes Spike had missed. Rainbow picked it up idly and glanced down at it ever so briefly.

She had expected to see magical and arcane formulae that made no sense to her - but what she saw instead was a name. Many names, in fact. Organized into a simple, two-column table, which repeated across the page a few times.. And she probably would have ignored it, except that her own name was on it near the top, which made it stand out to her eye.

"What?" she blurted aloud. Her name was right next to Rarity's name. Her hoof traced the column from her name up to the header. "Actual Pony?" She glanced over at the other column. "Turned into? Actual Pony: Rainbow Dash, Turned into: Rarity?"

That was last night. This table was...

Nopony was supposed to know who was who... right? Why did Twilight Sparkle have a table of transformations? No, that actually made some sense. Twilight was one of the few ponies who could have been in a place to make such a list. And she loved her lists.

Rainbow's eyes dropped back to the page. There was an entry for Applejack near the top, too.

"AJ inhabits Big Macintosh...? Heh, wow. Didn't expect that."

Curiosity overtook her completely as she briefly forgot about her nap and her personal predicament.

"Vinyl Scratch in Fluttershy?" Rainbow continued to read aloud. "I guess that explains why she was so quiet when Cheerilee went down on her. And why Fluttershy was in public." She shook her head. "Not Shy's style."

Another pair stuck out to her.

Twilight Sparkle | Mayor Mare

"Twilight Sparkle was Mayor Mare?"

That answered numerous questions about Twilight that Rainbow had never wanted to ask, and brought up so many more. Primarily, if Twilight knew who everypony was, was Twilight also into Dash, or just Rarity? And where had she learned to use her tongue like that? Cadance, perhaps? Rainbow had always suspected something was up there. She shook her head and went back to browsing.

Zephyr Breeze | Davenport

"Aww, buck me... I had sex with that loser?!" she blurted. "No wonder it was terrible. I'm so glad he'll never know."

Her eyes continued to wander the page.

"Pinkie Pie to Granny Sm— wait what? Granny Smith was swapped?!" Rainbow busted out laughing, thinking about Granny spending the night with a lover. "Oh, man, some stallion might have been for a rude awakening when the spell wore off! I wonder who the poor—"

—poor mares getting pregnant from acts they didn't consent to— Twilight's words echoed in her mind almost completely unbidden.

"—the poor stallion is." Rainbow finished, suddenly sobered. This wasn't the time for humor. Something serious was going on, and here she was snooping around and having fun at other ponies' expense.

She balled up her hoof to punch somepony. Somepony needed to... to... do... something.

She glanced down at the page again.

Pinkie Pie | Granny Smith

... And there was something there. Pinkie Pie was Granny Smith, but Granny Smith had always stayed out of the festivities. Always. Which mean Pinkie had to be involved somehow in the planning of all of this.

Pinkie knows something...

... About a Party Planning.

"On second thought, I should have seen that coming," Rainbow muttered.

"It was my fault!" Pinkie confessed.

Rainbow looked around, standing in the doorway of Sugarcube Corner. "Uh... I haven't even said anything yet," Rainbow replied.

"I know," Pinkie wailed. "But I know why you're here and it's terrible!" Her lip visibly trembled and tears ran down her cheeks as Rainbow approached the counter. "Are you pregnant?"

At the word pregnant, Rainbow felt that familiar itch in her nethers. She was still walking funny, but the satisfaction from the night before was already fading.

Rainbow glanced around the seating area to verify they were alone. After confirming they were, she turned back to Pinkie. "I haven't been to the hospital yet," Rainbow admitted. "But what I want to know is what in Equestria's going on! Why are you and Granny swapping places. And how? The potion is supposed to be random."

The color drained from Pinkie's face and dripped onto the countertop. Without missing a beat, she grabbed a rag and began sopping up the mess. "Uh... Granny Smith?" she said, with overplayed faux innocence, washing the countertop. "Who told you something like that?"

"That's not a denial," Rainbow pointed out, emboldened. "What are you hiding?"

Pinkie giggled nervously, wiping the sweat off her forehead with the now-pink rag. The color slowly restored to her face as she squeezed out the rag. "How'd you find out?"

"Oh, y'know..." Rainbow grinned devilishly at her victory. "Just doing some sleuthing. Spill it."

"Okay. Okay, Dashie. You've got me. But..." she looked around surreptitiously. "We can't talk about it here," she whispered. "Follow me upstairs."

Once they were in Pinkie's room, Pinkie bounded up onto the bed. "Come sit with me?" Rainbow shrugged and climbed up onto the bed next to Pinkie. "I'm sorry if I ruin the party's big secret for you," Pinkie said softly. "More than I already have, I mean."

It was obvious from Pinkie's less than bouncy demeanor that she felt terrible about this whole thing, but... "Why didn't you stop them?" Rainbow demanded. It was the one question that was plaguing her.

"He had already finished when we got to them. It wouldn't have helped anything." Pinkie sniffled and met Rainbow's angry glare. "And I couldn't ruin Granny's night! This party is one of Ponyville's biggest parties, and if I ruined it for Granny, it might not happen again!"

"Okay, but what does Granny Smith have to do with it?"

Pinkie's head drooped. "This is super-duper top secret," she whispered. "Only three ponies know. You have to promise not to tell anypony."

"I promise," Rainbow Dash replied, mimicking a long-practiced ritual. "Cross my heart, hope to fly, stick a cupcake in my eye." She had learned to stop actually hitting herself in the eye, but she still flinched every time.

"Every year, I join the mares' group," Pinkie explained. "And after I have transformed, we have a second batch of the potion prepared that allows me and Granny Smith to swap bodies. This year, I got yours."

"So you swap. Then what happens?"

"Then Granny takes that body and becomes a total slut, hitting on every stallion she can see and spreading her legs for any stallion who will rut her into next week."

Rainbow had heard rumor that some mare in Ponyville was secretly a sex fiend. The only indication had been Granny's parties, but nopony knew for sure who it was, as the pony in question never appeared outside of the party. Rainbow had always assumed it was Pinkie, since Pinkie was always down to fuck any other time anyway, but Pinkie had always insisted it wasn't her. And now it suddenly made sense.

What didn't make sense was, "Why would my dad have done that?" Rainbow wondered aloud.

Pinkie's shoulders slumped. "I don't know, Dashie."

"He cheated on my mom!"

"You do look a lot like your mom," Pinkie replied. "Maybe he's secretly into blue mares?"

"Well, now he's been into me in more ways than one," Rainbow sighed in resignation.

Silence fell on the room for a few moments. Rainbow couldn't help but think about what she'd seen the night before - that vision of her father, seeding her like his stallionhood depended on success. It wasn't intrusive as it had been when she was falling asleep. She wasn't horny the way she'd been in Rarity's needy body, just sore. And yet the arousal was there as she thought about it. That accursed desire.

"Granny stopped by this morning to thank me," Pinkie confessed, derailing Rainbow's wandering thought. "She said it was the best party she's ever had, and she'd never felt so satisfied since a wandering stranger knocked her up with Bright Mac."

What. "Okay, we can unpack that later, Pinkie. Why are you telling me this?"

"Because it means you really need to go to the hospital and get tested."

Dinner with her parents was the last thing Rainbow wanted to do. She wasn't angry, she was just... unsure. Even if it meant having the most uncomfortable discussion she'd ever have in her life, she wasn't... mad, per se. And here she was now, at her parents' front door, her pregnancy test results in her saddlebags. They taunted her, daring her to tell them the terrible truth.

Her mother was the first to answer the door. "Rainbow Dash!" she said, beaming. "Oh, what a surprise!"

Her father trotted up behind Windy. "Hey, squirt!" Rainbow flinched at that choice of words. "We haven't seen you in a while!"

Rainbow pushed past her mother and into the living room, shrugging her saddlebags onto the couch. "I saw you at the party," she mumbled as she passed her father. "It hasn't even been a day."

"Ah, so you saw us there," Bow laughed, following her. "I admit, I was curious if you knew."

Us. Which meant her mom was there, too. Rainbow had been spared discovering that one in-person.

"We didn't know who you were, though," Windy added.

Rainbow closed her eyes and took a deep breath. When she exhaled, she turned and her eyes opened, gaze levelled firmly on her father. "What. The. Buck, Dad?!" she spat. "You had sex with me!"

"I... what?" Bow took a step back. "Hold on, now. We know the rules of the party."

"Obviously you didn't!" Rainbow retorted.

"But that wasn't you, dear" her mother insisted, interposing herself between Rainbow and her dad. "It just looked like you."

Rainbow's anger turned toward her mother. "And that doesn't bother you?!" she shrieked.

"Now, hold on," Windy said calmly, "I know it looked bad, but it wasn't actually you. There's nothing wrong with living out a little fantasy now and then. Isn't that the entire point of the party?"

Rainbow's shoulders drooped. She was technically correct, but— Rainbow finally met her mother's gaze. "How are you just 'okay' with this?" she whispered. "He cheated on you. With a literal replica of me."

"I gave him a pass. Your father and I have a history of things like this, y'know."

Rainbow stepped back and fell onto the couch. "Wait, you... you do?"

"Of course. He's always been free to pursue other mares. And when there's no risks, what's the harm?"

Rainbow deflated, and suddenly felt far more... relaxed. He hadn't been cheating! That was the source of stress she hadn't been able to identify. That was the concern that had been gnawing at her - that her parents' marriage was falling apart. Except, now...

"Wait, he fantasizes about having sex with me?!" Rainbow said, incredulously.

"Oh, honey, we both do," Windy replied matter-of-factly, taking a seat alongside her father on the loveseat opposite the couch. "Athletic, toned bodies are the best. Why, I took a ride on Thunderlane's stallionhood last night, and it was absolutely divine!"

"Mom, I don't need to know-" A memory of the year before floated back to her. "-okay, I don't disagree with the thing about Thunderlane, but you guys are my parents. You can't just be going off and having sex with a pony that looks..."

Rainbow paused to gain the courage to say it. "...You can't have sex with a pony exactly like me." She glanced at her father and a brief moment of frustration bubbled up. "That was actually Granny Smith, you know!"

Bow simply shrugged. "Older mares know what they want and how to get it. I'm not complaining." Rainbow had to admit she'd expected that barb to land a bit more firmly. "I hope she had a good time," Bow added.

She did. Rainbow wouldn't say it aloud.

"Look, Rainbow," Windy chided. "I understand you're upset, but please know that Granny Smith came onto your father very hard. He actually tried to resist at first, because of what it would have looked like, but she kept throwing herself at him, and I... I kinda started encouraging him. It wasn't you, and I thought it would be hot to watch."

"Are you bucking serious?" Rainbow blurted.

"It's okay, it's not like he actually had sex with you."

"He actually got me pregnant, though."

Her parents' faces each went through a myriad of silent emotions - confusion, dread, horror, and delight, only for both of them to settle on confusion.

"Come now," Bow said, laughing hesitantly. "The flier said no pregnancy risk. They were using magical contraceptives, right? So the mares are never actually fertile?"

"Look, I don't know about the specifics of the spell," Rainbow confessed. "But because you were in your original body, you were fertile."

"B-but pregnancy control is supposed to be a mare's responsibility," Windy argued. "I always took care of myself first at parties like that. Any mare knows that the responsibility lies with both, but the risk is hers alone to bear, so..." she trailed off.

"Not every party is the same, I guess..." Bow mumbled. "Shit, Wind... Maybe we fucked up." He slumped back in his seat. "I got... my own daughter pregnant? Then how...? What do we do now?"

"Yes, what are you going to do?" Windy echoed, fixing her gaze on Rainbow Dash. "Are you going to keep it?"

Rainbow paused. She hadn't considered at all what she might do with the foal. The thought of raising a foal terrified her, but nearly every straight mare would do it at some point - the heat of estrus practically demanded it every year, only getting stronger as she got older, and it was rare that anypony managed to resist the call forever. And she did have this weird, nebulous desire to have a foal eventually, though she had a hard time visualizing who the stud would be.

She looked up at her father, who was calmly looking back at her with deep concern. Would it really be so bad to have it now, while her parents were still able enough to give her help, physically and emotionally?

Rainbow sighed deeply. "All of my friends have siblings, and sure, sometimes they complain, but... I've always kinda felt left out," she admitted.

"What?" Bow blurted.

Windy tilted her head. "What about that little filly, Scootaloo, I think? She's kinda like a sister, isn't she?"

"Yeah," Rainbow said with a dry chuckle. "But it's not the same. She has her own home and her own life to go back to when we're done hanging out. But now..." Rainbow sat back in the chair and touched her stomach gently with her hoof. "Now there is a little brother or sister in here. A real one. And I would hate to be the reason that I don't get to meet them."

"So, you're keeping it?" Windy said, eyes shining hopefully.

"I... won't abort," Rainbow agreed, hesitantly.

"Rainbow, I'm sorry," Bow said morosely. "She came onto me real hard. I really did try to tell her no at first, but... she insisted. A lot. And then your mother started encouraging it... I shouldn't have given in to the urge."

"It's okay," Rainbow replied. "I've already made peace with it. You didn't know this would happen. And it was kinda hot to watch."

Windy giggled. "It really was."

Bow sat up straight, staring at his daughter. "You were watching?"

"For a little bit," Rainbow confessed. "I kinda panicked and ran away."

The memory of his massive erection— her eyes briefly wandered down her father's chest before going wide. That wasn't just a memory! Her father was slouched in front of the chair, with a raging hard-on! The one that was responsible for the soreness she'd been feeling in her nethers all day.

"Dad, what the buck?"

Bow glanced down, gasped, and quickly tried to cover himself.

"Aww," Windy cooed. "I was enjoying the show."

"Windy!" Bow shouted. "Read the room!"

"I am reading the room," Windy said demurely, leaning in to lick the tip of his muzzle. "What are you reading?"

Rainbow's breathing was growing more shallow as she gazed at her father's midsection. Despite his efforts, it was still in plain sight. And her mother's distractions were preventing him from doing anything about it. A perverse desire was raging, welling up inside of her.

"...do I..." she whispered, slowly standing.

"Hmm?" Windy hummed, kissing her husband on the nose while looking at her daughter from the corner of her eye. A small smile crept onto her face. Rainbow's tail was flagged.

"Do I really turn you on that much...?" Rainbow asked softly.

"No!" Bow cried out, never looking away from Windy.

"You do," Windy confirmed, undercutting Bow's reply. "He's had that fantasy for a long time."

"Windy!" Bow bellowed. "What are you doing?"

"Dad, look at me." Rainbow commanded, sitting back on her haunches.

Bow's eyes stayed locked on his wife for a few terse moments before slowly angling his head to look at Rainbow. His eyes shimmered with tears threatening to be shed. Rainbow laid a hoof to her stomach. "Dad, I'm pregnant. And it's your fault."

Bow nodded quietly.

"But I never—" Rainbow stopped herself. She stood up and took two steps toward her father. "I have never thought of you in that way, but now..."

"Rainbow..." Bow blinked a few times, trying to clear the tears away. "What are you saying?"

"I saw it," Rainbow repeated. "I didn't see everything, but I saw enough. You gave me a good time." She grimaced and nodded toward her flagged tail. "And I felt it in the morning. I'm not upset that I'm pregnant. I'm a little upset that you had sex with my body. But... I'm mostly upset that I didn't get to experience it."

"Huh?" Bow uttered, confused.

Windy's eyes went wide. "You aren't seriously suggesting...?"

Rainbow turned to her mother. "I need to do this, mom. Think about it. You go to a party and get really drunk. You find out later that you got knocked up, but you don't even remember the sex. You want to love your foal, but you can't even remember the moment they were conceived. You can't ever be completely sure of yourself who the father is. The doubts plague you. It eats at you."

"Hmm..." Windy nodded. "So you create a memory for it. You saddle a stallion with that burden, letting him think that it’s his own."

"But you know it's mine," Bow stated flatly. "And that's a terrible thing to do to a stallion."

"I know," Rainbow said. "I know, but... I need this. For me. For my own memory. My own well-being.” She paused and turned to Windy. “That is, if... if you're okay with it, mom."

"You have my blessing," Windy replied, smiling softly. "But... if I could just make one request?"

Rainbow nodded.

"Could I... maybe... if you don't mind..." Windy pointed a hoof at herself.

"Make it a threesome?" Rainbow asked.

"No, not quite," Windy said, shaking her head. "But if you're okay with it, that would be fine, too."

Hometown Horseplay for Family Fun

Rainbow Dash felt her father's hoof upon her shoulder. Her eyes broke away from her mother to gaze up at him. His face wasn't the warm smile that she'd expected, but instead a jaw set with determination.

"Are you sure about this, Rainbow?" he asked. "I wouldn't want to hurt you."

Rainbow nodded, the burning between her legs flaring up with desire and a dull throbbing ache from the previous activity. She survived that pain, she could survive more. "I can handle it, dad. Give me everything you’ve got!"

Bow nodded and stepped behind her. Rainbow bent her forelegs slightly, her tail was flagged to the side and quivering uncontrollably. Her body was begging for its trove to be filled with life-bearing treasure. Bow nuzzled under her tail, and she felt the roughness of his tongue against the entrance to her sanctum. She gasped and closed her eyes as her neck craned back with pleasure. “Oh, buuuuuck…” A wispy moan escaped her lips.

It was strange. The feeling itself, so familiar and yet so alien at the same time. Part of her knew this was wrong - that she shouldn't ever do something like this with her own father. But an equally powerful craving for him to deposit his seed within stopped her from acting out.The taboo duality of it sent a thrill up her spine.

A strange feeling of something tickling at her ear drew her attention away from the tongue grinding against her cleft. She opened her eyes to see Windy sitting on her haunches and nipping softly at Rainbow’s ear. In between gentle nibbles, Windy's tongue delicately traced the inside of Rainbow's ear, and a quiver went down her spine. That was something nopony had ever done to her before. Wired up as she was, she nearly melted under the sensuous assault.

"We love you so much, Rainbow," Windy whispered intimately. Her lips moved away from Rainbow's ear, tracing down the side of her muzzle, planting soft kisses the entire way. Without even thinking, Rainbow turned her head and their lips met. And then, Rainbow suddenly found herself Prench kissing her own mother.

It wasn't anything like kissing other ponies - not that Rainbow had much experience in that regard. Her previous kisses had been mechanical and perfunctory - born of lust and performed only because it seemed like 'the thing to do' with a random hookup.

But this? This was different.

Her mother's kiss was slow and sensual. The subtle sounds of lips parting and pressing together again hit Rainbow differently than the frenzied face-mashing she’d experienced before. The tongue invading her maw was soft, gentle, and most of all, curious. Rainbow responded to the probing tongue with her own exploration, hesitantly exploring her mother's mouth. Windy responded to this by wrapping her tongue around Rainbow's own and pressing their lips firmly together. It tasted like petrichor smelled - a pleasant hint of rain and earthen softness, instead of alcohol breath and stale cigarettes. Rainbow's heart swelled with a sensation of peace and comfort in the hooves of this mare: the one who had always been there to comfort her, even when she didn’t want it.

Is this what love is? she wondered.

It seemed like such a strange question - of course she loved her mother. But this love was different from the love that came before. It was more tender; more personal; more sensual.

Her mother's lips pulled away, and Rainbow could see a rosy tint in those sky-blue cheeks. Somewhere along the journey, her father had stopped tending her rear garden, but she'd been so wrapped up in the kiss that she hadn't even noticed. Right now, all of her attention was on her mother. Windy leaned back, wrapping her forehooves around Rainbow's neck and pulling Rainbow forward ever so slightly.

The fluffy cloud surface of their living room floor made a slight *pomf* as Windy's back fell against it, and Rainbow suddenly found herself standing over her mother's form with her mother’s hooves holding her there. She gazed down at two mounds and a patch of moistened fur that surrounded the very gateway from which she'd once entered this world.

Her mother's expression was something Rainbow had never seen before - a come-hither gaze that signaled an intense desire for Rainbow, and the things Rainbow could do for her. "Use your tongue?" Windy pleaded, sounding more desperate than Rainbow had ever heard in a partner.

“Okay,” Rainbow replied without hesitation. The scent of Windy's arousal was powerful as Rainbow's muzzle approached. Content to tease her mother, Rainbow flicked one of her mother's nipples with her tongue. Windy had only asked that Rainbow use her tongue - but not what to use it for, after all.

“Mmph!” Her mother seized up and let out a cute squeak, so Rainbow did it again to the other one, going back and forth a couple of times before enveloping a nipple completely and suckling softly on non-existent milk. Windy squirmed under Rainbow the entire time, her hooves resting on top of Rainbow's head and desperately trying to push Rainbow lower.

I've done this before, Rainbow realized, rolling the nipple on her tongue. But I didn’t think I’d ever do it again. The idle thought brought a smile to her face, but her mother's stiffening wings, pleasured gasps, and adorable vocalizations only made Rainbow want to do even more. And, judging from the gushing wetness below, Windy was ready, too. Rainbow released her mother's nipple with a pop and began kissing down over Windy’s mons, before moving onto the thick, slickened flesh of her mother's labia.

Rainbow was no stranger to a mare's private parts, and she knew what she was doing. Her tongue—

"That's my girl!" Bow suddenly hollered.

With only that as her warning, her father's hooves locked to her sides, right under her wings, as he mounted up behind her, putting a not-insignificant weight upon her hips. He thrust his hips forward in one smooth motion, his cock rubbing against her clit as it ground against her groin and the shaft nestled between her teats.

His forward thrust drove her muzzle harshly into Windy's drooling pussy, taking what Rainbow had intended to be a slow introduction to cunnilingus into an impromptu muff-dive. She inhaled sharply in response to the sudden motion, breathing in the potent smell of a hopelessly aroused mare.

It was intoxicating. Rainbow could only imagine how potent such a scent must be for a stallion.

Bow pulled back and Rainbow felt his throbbing erection slide away from her teats, her clit winking madly at the rough touch of his rod gliding across it. Her vision - along with her sense of smell and taste - was now dominated almost entirely by her mother's crevasse, and she could no longer see what was going on around her, but she could feel her father lining himself up for the main event. He had been careful not to pin her wings down, and she was thankful for that, because her wings were extending on their own.

At first, Rainbow closed her eyes, bracing for the inevitable penetration, but Bow's cockhead merely dragged itself up and down her moistened slit. Through it all, Rainbow had never let up with her tongue, her own growing anticipation driving her to a frenzy as she focused on her mother's bulbous, needy clit. She reached forward with a hoof to caress her mother's teat, and briefly considered trying to catch her mother's winking clit with her teeth to tease the poor mare before realizing that Bow might unexpectedly cause her to bite down on it. Windy, still holding Rainbow's head down, was tensing up under the sustained stimulation, and Rainbow was sure that she was getting close.

"Okay," Windy gasped.

Before Rainbow could even stop to ask what was wrong, she felt the pressure of a mammoth cockhead pushing against her slickened sanctuary. The sensation disappeared quickly, the pressure releasing as his shaft split her folds. It was thick, pulling her labia taut against his stallionhood, and Rainbow could swear that she felt every last detail of the veins. She was filled in a way she'd never felt before; even Thunderlane's magnificent endowment had nothing on the sheer fullness she was feeling.

“Oh! Gooooooodessssss!” Rainbow moaned in ecstasy, the vibrations of her pleasure transmitting straight into her mother's sanctum. Her mother's body seized, and the sound of Windy's own ecstatic scream tore through the air. A fountain began gushing forth, dousing Rainbow's muzzle. Still stunned from her father's penetration, Rainbow's mouth was half-open and moaning, giving her a sudden mouthful of the thick, tart fluid.

Bow pulled himself back, leaving Rainbow feeling momentarily lost. It was as if a part of her had left with him. And then he slammed back into her, shoving her muzzle roughly into her mother's orgasming slit. And then he did it again.

“Your body is just amazing,” Bow groaned. He began thrusting, and Rainbow felt Windy's hooves grip her head even more tightly, pulling roughly. As Rainbow tried to figure out what her mother was doing, Bow thrusted deeper and deeper - he'd hilted already, yet somehow continued deeper still, as if his erection hadn't yet grown to its full glory. He eventually began to tap against her cervix, a slightly painful touch in the midst of the pleasure that only amplified the feelings.

Using Rainbow’s own head as leverage, Windy pulled herself up into a sitting position, holding Rainbow's face against her sensitive parts. Windy angled her head up to meet Bow's lips and her parents shared in an intense kiss right above her. Rainbow continued to lap at Windy's engorged folds, oblivious to the makeout session going on above her. Bow slowed his thrusting as they continued kissing, and after a few moments of weaker, less enthusiastic thrusting, Rainbow felt him withdraw completely. Even Windy pulled herself from under Rainbow's ministrations, her thoroughly soaked tail dripping femme fluids onto - and through - the cloud carpet.

That encounter had been so short-lived. Her body was screaming for her to finish. "...Dad?" Rainbow asked, half-afraid he'd changed his mind. “Is something wrong?”

"No, Rainbow," Bow replied, fiddling with the cloud carpet.

"Then why'd you stop?" she asked, her voice shaking with lust and fear all at once.

Windy draped a wing over Rainbow and leaned in for another Prench kiss. "Because, Dashie. He wants to see your face." Their lips met again, and when her mother pulled away from the kiss, she noticed her father had raised a cloud puff just large enough for Rainbow's body to lay upon - and just high enough for Bow to mount.

"Oh." Rainbow blushed as she realized what that meant. She carefully and somewhat painfully folded her wings, and then rolled onto the massive fluff of cloud. It was like laying on a bed of pillows. "You mean like this?" she asked, spreading her hind legs.

Bow trotted up to her, and though he was smiling, it was a serious smile. "Are you absolutely sure about this? We don't have to keep doing this," he said anxiously. "I shouldn't even ask you to do this. We can just..."

That wasn't how this was supposed to go. "Huh?" Rainbow blurted. "What do you mean?"

Bow ran a hoof through his colorful mane. "I mean, back at the party it was... well, cover position. I knew it wasn’t actually you. There was nothing personal about it - just two ponies getting some sexy stuff out of their system. But just now, I couldn't... I couldn't sit there knowing it was actually you and just go through with it."

"Okay?" Rainbow replied, still not understanding. "Are you feeling guilty about it?

Bow nodded. “Yeah, I am.”

“And then, what? I just go on being pregnant and you leave me wanting? I came here to hopefully feel better about this."

"No!" Bow shouted. "No, you don't understand! I mean, doing it face-to-face is different. It's going to be a lot to take in."

Rainbow peered between her own legs to see her father's flagging erection. Clearly he was concerned, but for whom, she couldn't be sure. Perhaps both of them.

"Dad," Rainbow replied, extending a hoof. "I've already decided I want this. Now, come kiss me like you do mom."

The silence that hung between them stretched far enough that Rainbow was concerned he wouldn't follow through.

"Dear," Windy spoke up, drawing his attention. "I can see it in her eyes. She wants this. She wants you. Just as much as I've ever wanted you."

Rainbow couldn't deny it. She wanted to feel him again. Her tail was pinned underneath her, exposing herself completely to him, and her wings were so swollen with arousal that she couldn't fly if she wanted to. She nodded. “I need you, daddy.”

"Okay," Bow conceded. He gingerly stepped over Rainbow and bent down to meet her lips.

Her mother's kiss was sensual and intense. Her father's kiss was more like what Rainbow had become accustomed to - rough and firm, yet there was a sincerity to it that had been lacking in the others. Rainbow pushed her lips against his. He made no move to use his tongue, and neither did she. That was okay, too.

And then they pulled apart. Her own father was standing over her, and Rainbow couldn't help but look down to where his pendulous testicles swayed, his erection slowly returning. Bow grabbed Rainbow by the chin and pulled her eyes up to face him.

"I want to gaze into your eyes while we make love," Bow replied tenderly. "Is that okay?"

Rainbow's heart swelled. No one had ever asked her to simply make love. Everything had always been about getting eachother off as quickly as possible. But her parents? Her parents were... different. If she was going to bear his foal, this was how she wanted to experience it. This was how she wanted to remember the conception: something tender and perfect. Now she knew for certain this was what she wanted, and there would be no regrets.

She smiled up at him and simply nodded her consent, unable to properly form the words to convey how she felt. Bow smiled back and his head bent down next to her as he shuffled forward. Rainbow felt his mane against her fur as his head lay right next to hers. He was shuffling around below, and she knew he was getting into position.

"I love you," he whispered next to her ear. "I've always loved you. I'm sorry for what I did, but thank you for letting my dream come true."

Rainbow had already forgiven him for the last night's transgression. "It's okay, dad. Tonight, I want you to love me. Not just as your daughter, but as a mare and a mother to your foal."

He pulled back from her ear and their eyes met. The head of his shaft was at her entrance again. She could feel it there. Rainbow smiled slightly at his uncertain expression. "I mean it."

That was all Bow needed. Their eyes remained locked as he slowly parted her folds, sliding into her again as if he belonged there. And as he went deeper, Rainbow knew that she belonged around him.

He began to move. It wasn't rough or fast, as he had done minutes before, but instead it was slow and sensual. At this pace, she could feel the way his medial ring crossed her folds and into her body - a sign that he was about to bottom out, immediately preceding the kiss of his cock against her cervix. A light, delicate touch instead of a painful shock.

"Oh, my stars," Rainbow gasped. "That feels amazing, Daddy."

For Bow's part, Rainbow had clamped down on his dick like a vise, and even if he wanted to go faster, he wasn't sure he could without harming her. "You feel amazing, Dashie," he replied, beaming. “Just remember, this one is for the memories.” Her body didn't want to let him go, her desperate muscle contractions making a slow withdrawal difficult but intensely pleasurable.

He pushed himself back into her, slightly faster, but still far slower than anything else that had come before, before pulling back out and pressing into her again.

“Mmmph!” Rainbow squeaked as his hips crashed into her butt, filling her as deeply as he could.

"I'm going to give you a foal," Bow reminded her.

"Oh, ffffffuck, that’s hot," Windy's strained voice could be heard from somewhere else in the room, along with the sound of gushing liquid splattering on the cloud.

"I think mom approves," Dash said, giggling. "Come on, Daddy. Make me a mom."

With a smile, Bow pulled her in close and hugged her tightly. Rainbow pressed her head against his shoulder, breathing in his alpine scent as she relaxed into his blissful embrace. His thrusts grew short and powerful, and Rainbow could feel the familiar thickening that all stallions did right before they finished.

“Mmph! — Oh! — Dad — I — love — you," Rainbow gasped with the pressure of each thrust forcing a quick breath. "Come — and — breed — me!"

Bow didn't need to be asked twice. His member pulsed, flaring at the tip as Rainbow felt a copious warmth deep in her core. That was all she needed as she peaked, her forelegs grasping for her father and holding on as if her life depended on it. The world went white with pleasure as she clamped down on him, gushing copious femme cum all around his member, soaking his balls and spilling onto the cloud carpet below.

All movement stopped. Bow and Rainbow embraced each other tightly as his dying orgasm filled Rainbow so much that his cum mixed with hers and oozed back out, dripping onto the cloud beneath them.

And then the two lay there, each gasping for air.

"Oh, thank you," Windy said, breathing heavily herself. "I needed that."

Rainbow cracked an eye open to see her mother, hooves still resting between her legs and sitting in a pool of her own emissions.

"You're… welcome?" Rainbow said, haltingly.

"Yeah, any time," Bow replied.

"I wasn't talking to you," Rainbow chided.

"I was talking to you, though," he countered.

... Any time?

"Sure,” Rainbow smiled. “Any time. But only until the baby is born.”

In truth, though... she could get addicted to this. As long as her mother was okay with it, she would probably be back soon.

Twilight stepped into Rainbow’s kitchen. “It’s been a week since I’ve seen you, Rainbow! Where have you been?”

“At my parents’ house.”

“Well, I’ve been trying to get hold of you. I’ve got good news!” she said, beaming. “There’s no need to worry anymore, because you’re definitely not pregnant!”

Rainbow stared at her, unimpressed. “I went to the hospital, Twilight, like you and Pinkie told me to. They tested me and confirmed I’m absolutely pregnant.”

Twilight’s hooves dropped to the table. “What?”

Rainbow fished around in her saddlebags for the paperwork.

"But it's just not possible," Twilight mumbled. "None of the other six mares got pregnant."

"Well, this looks like a positive test to me!" Rainbow cried, waving the pregnancy test results frantically in front of Twilight. "I hadn't had sex with anypony before the party, and I took the test the next day! There's no way it's not his! Besides, how can you say it’s not possible to be pregnant? We know for a fact that he didn’t take the potion."

"Because!” Twilight argued. “Zecora helps make the potion base for the ceremony every year. Naturally, I went to Zecora's to see about getting all of the mares a morning-after solution before this turned into a major PR disaster.”

“Okay?” I wouldn’t have taken it anyway. Rainbow kept the silent part to herself. Instead, she pressed for more. “What does that have to do with it?”

“After I told her what happened, Zecora said - and I quote -” Twilight held up her wingtips to indicate quote marks.

The Potion brewed is quite selective

Moon Tea Leaves keep it effective

For mares who might still be receptive

To stallions who don't heed directive

I do not think it too protective

To keep foalbearing an elective

“- unquote.”

Rainbow shook her head. "Care to translate that into laypony’s terms?"

Twilight’s frustration boiled over and she threw her hooves up. "It’s plain as day, Rainbow! Moon Tea Leaves are extremely powerful contraceptives. Nopony was ever at risk of pregnancy."

The absurdity of Twilight's claim hung between them - there was no way it was true; she had the pregnancy test in her hooves. "Then how did I get pregnant?" she challenged.

"I... don't know," Twilight confessed.

A pounding on the door interrupted the awkward tension in the air.

"Come in," Rainbow Dash hollered.

The door swung open, and in the doorway stood a grey, wall-eyed pegasus. "Ah, Rainbow Dash!" she shouted, waving a sheet of paper in the air. "I keep trying to find you. The hospital mailed me your pregnancy test results on accident! There must have been a mix up."

A sudden horror gripped Rainbow Dash as she peered down at the paperwork in her hooves. Sure enough, right there in the corner of the page - a tiny detail Rainbow hadn't noticed in her initial panic.

Patient: Derpy Hooves

Twilight reached out a comforting hoof. “That’s great, isn’t it?”

“This isn't mine?!" Rainbow shrieked, slamming her hooves on the table. "NOT MINE?!"

"Calm down, Rainbow," Twilight chastised her. "This is good news! Derpy and the Doctor have been trying to conceive for years! You should be happy for her!"

That was not the problem, here. "Sure, congratulations, Mrs. Hooves!" Rainbow said stiffly, standing up and trotting toward the now-open door.

"Rainbow?" Twilight asked, confused. "Where are you going?"

"To take a test."
