Party Crasher

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."
