Following their confession to their mother, as well as their subsequent punishment and the pleasant meal following that, the royal sisters bid their mother a fond farewell and started flying back to Maretime Bay. While their bottoms still hurt, the redness had gone down so it wouldn't be noticeable when they walked through town.
As they flew, their eyes couldn't help but get moist, so much so that tears flowed freely from them. It was a daunting task, but their mother told them everything they wanted to hear and gave them her support, as much as she could anyway.
While she hadn't completely accepted their relationship, she hadn't shunned them, either. She didn't disown them, or yell at them or turn their nose up at them in disgust for being in a taboo relationship. And that was more than enough for them.
They flew in silence for a while before finally turning to each other.
"Hey." Zipp spoke up with a smile.
"Hey." Pipp smiled back.
"So… that actually went better than expected." Zipp commented. "You know… minus our hindquarters still hurting."
"Yeah… Do you really think Mom was ok with it?" Pipp wondered.
"Honestly? I don't know. She didn't completely approve of it… " Zipp admitted. "But it feels like we have her support."
"Yeah… She wasn't as upset about it as we thought." Pipp added. "And the parts she was upset about, weren't the parts we thought she'd be mad about."
"Yeah… Feelin' better?" Zipp Storm inquired.
"A little. I don't know… kinda feels… weird, you know?" Pipp Petals remarked.
"Guess that's to be expected when you admit to a loved one that you're banging your relative." Zipp commented.
"Zipp!" The pink Pegasus lightly scolded her. "Be serious, would you?"
"Sorry, just trying to make you laugh." The older sister said.
"Yeah, I know. And I appreciate it." Pipp nodded. "Well, at least we don't have to worry about Mom and her freaking out about it anymore."
"Yeah… And we can totally be as physically affectionate as we want around her too. Well… within reason anyways." Zipp added.
Pipp smiled. "Yeah! You know… an achievement like this deserves a celebration!"
Zipp smirked with a raised brow. "Picnic date?"
"You read my mind." Pipp smiled with a wink. She winced as she reached back to stroke her backside. "But maybe after our heinies stop hurting?"
The older sister rubbed her own rear. "Good idea," she frowned.
Noticing her big sister/secret lover's disappointment, Pipp extended her hoof toward her with a loving smile. "We can still hold hooves though,"
With a sweet smile of her own, Zipp touched hooves her little sister/girlfriend. The two continued flying like this all the way to Maretime Bay.
Upon returning, they quickly informed their friends about what happened with their mother and let them know that she supported them. All of them gave them their congratulations, and purposefully didn't ask for any details in order to maintain plausible deniability.
Once their rumps stopped hurting, Zipp and Pipp decided it was finally time to go on that picnic date. While they felt more comfortable giving each other physical affection then before, they still decided to disguise their manes and cutie marks in case somepony came by.
Even though they didn't tell their friends about it, they didn't hide it either, even purposely putting on their disguises with one or two of them present before leaving at different times.
Sunny watched Zipp step out of the Brighthouse with a wig on and a fake cutie mark over her real one and smiled. Izzy rose up near her with a smile of her own and startled her when she spoke.
"So, you getting used to them 'doing it' in secret on a daily basis?" she inquired.
"Izzy!" Sunny scolded. "You know you don't have to put it that way."
"Oh! Sorry!" Izzy whispered. "Are you getting used to them 'making love' in secret on a daily basis?"
"Hmm… more or less." Sunny admitted as she and Izzy made their way over to the living room. "I mean… I'm grateful that they give us a heads up about it, without saying exactly what they're doing, that is… and I'm happy to give them privacy when they ask for it. It's just… hard not to imagine what they're doing.
"Such is the price of not knowing… And having a great imagination!" Izzy stated cheerfully. "Course for me, it's more of a blessing than a price."
Sunny sat herself down on the couch. "I also wanna know exactly where they have their 'fun', but…"
"Oh, then you probably don't wanna sit there." Izzy spoke up. "Because… that's one of the spots they did it."
The orange Earth Pony yelped and quickly got off the couch.
"Relax! I cleaned it afterwards!" The unicorn assured her with a smile.
Sunny smiled in relief and sat back down. "As I was saying… I wanna know, yet at the same time… I don't wanna know."
"Oh! Gotcha!" Izzy saluted understandingly.
"There is something I am curious about though…" Sunny Starscout admitted.
"Like if they also swap gum?" Izzy guessed. "Because, you know, once you start kissing…"
"Izzy!"
"Sorry!"
"What I'm curious about is if… what kind of future do they see for themselves? Like… do they see themselves… I don't know… getting married or something?"
The unicorn gasped sharply. "A sister-sister marriage!? Oh, wow! That sounds super fun!" Izzy exclaimed excitedly.
"It is, but…" Sunny began before Izzy cut in.
"Ooh! Do you think they'll have kids too?" Izzy wondered.
Sunny giggled a little in amusement. "Izzy, you know two mares can't have a baby."
"Yeah… But you can bet your bottom that they keep trying!" Izzy pointed out. "Not to mention… magic!"
"I'm… not sure magic can help two ponies of the same gender have a baby… But then again, Twilight did say magic is constantly changing and growing." Sunny recalled.
"Exactly! So who knows what could happen if Zipp and Pipp's love keeps growing and growing and growing and growing…" Izzy said before Sunny cut her off.
"I… think I get it, Izzy."
"Great!"
"I just hope they're able to keep being discreet."
"Relax, Sunny! They have disguises! So as long as they put them on when somepony happens to be passing by, nopony should be able to recognize them!"
"Yeah, maybe…" Sunny Starscout muttered, feeling both hopeful and unsure.
Izzy let out a deep sigh as she sunk in her seat. "I wish I could find my own special somepony…"
Sunny came closer and wrapped a foreleg around Izzy. "Aw, don't worry, Izzy. I'm sure you'll find somepony special some day."
"Thanks, of course it's easier for you to say." Izzy commented.
The orange pony tilted her head. "What makes you say that?"
"Well, I mean… you and Hitch…" Izzy began before a flustered Sunny started blushing.
"What?! No! No. Me and Hitch? We're just… friends. Very good friends, that's all!" Sunny insisted.
"I don't know… you two are awfully close. I mean, you know each other better than anypony, you grew up together, you even have a super cute special hoofshake!" Izzy pointed out. A sly smile slowly appeared on her face. "Are you sure you're not…?"
"Izzy…!" Sunny moaned in embarrassment as she covered her face with her hooves while the unicorn giggled.
Elsewhere, a now undisguised Pipp and Zipp were happily enjoying their picnic date in a small clearing in the woods that Zipp spotted while flying by. Surrounding the grassy ground are so many trees and cute animals running around. Since Pipp would rather get a bad mane cut then sit on the grass, Zipp made sure to bring a picnic blanket for them to sit on.
Also set between them was the picnic basket and all the food they brought, which they happily fed to each other from time to time.
Pipp pulled Zipp in close as she held her phone up. "Alright, say 'Picnic date!'" she exclaimed happily.
Zipp sighed. "Pipp… this is the fifth picnic date selfie in a row…" she complained.
"Oh, don't be like that." Pipp brushed her sister/lover off. "Besides, it's not like they're all the same. Like this for example! Mwaa!"
Pipp happily gave Zipp a kiss on the cheek as she took a photo of them. "And now on the lips," she said expectantly while wiggling her eyebrows.
Zipp playfully rolled her eyes. "Ok…" she said before kissing Pipp just as she took another photo. "Just don't post 'em."
"I would never!" Pipp remarked, pretending to be insulted before giggling. "They're for my own private collection."
"Hmm, just like all those booty shots I have of you." Zipp smirked.
"Ugh, I can't believe you keep all that on your phone…" Pipp whined in embarrassment.
"One of them is even my wallpaper." Zipp revealed in a teasing tone.
"Zipp!" Her little sister/lover exclaimed.
The white pegasus laughed. "I'm kidding! Relax!"
Pipp huffed. "I swear…" she remarked, trying to look frustrated, but a small smile still appeared on her face. She sighed as she gazed around. "Well… it's nice out. Plus, it's just the two of us, all by ourselves in the outdoors."
"Bet you'd be complaining more if you couldn't connect to the Canternet out here." Zipp quipped.
"I would not! Though… I would be a little sad." Pipp admitted, blushing a bit.
Her older sister pulled in closer. "Aw, now why would you be sad when you got me for entertainment?"
The pink pegasus giggled. "Yeah, true."
"Guess I have to make sure you're extra happy the next time you can't go online." Zipp commented suggestively, something Pipp quickly caught onto.
"Ooh, can't wait." Pipp grinned, trying and failing to contain her excitement while her sister stroked her mane affectionately. "Like it? I had my split ends trimmed, a hot oil treatment and subtle violet highlights just for today."
"Oh, so that's what you did. Cool! I couldn't tell exactly what you did with your mane, you know, since I don't get all the beauty stuff." Zipp admitted.
"Really? I hadn't noticed." Pipp sarcastically remarked.
"But I could tell that it made you even cuter then you usually do." Zipp smiled.
"Aw, Zipp!" Pipp said, touched. She gave her girlfriend/sister another kiss on the cheek, making her giggle before she herself joined in.
"But you know, even if you were bald I'd still think you looked cute." Zipp admitted.
"Please don't bring up my worst nightmare…" Pipp shuddered. "Oh… you have no idea how weirdly shaped my head looked in that dream!"
"A weird thing to be scared of..." Zipp commented slowly.
Noticing that Pipp was still a little shaken by the unpleasant memory, Zipp decided to cheer her up by pressing her lips against hers. She soon started to hear Pipp's phone making the sound it makes every time a photo is taken as they continued to playfully make out in the clearing.
Their ears perked up when they heard a distant flapping sound and realized that somepony was flying by. Shortly after they separate, they quickly put their wigs and fake cutie marks on just before a female pegasus pony starts to fly by overhead. The sister sighed deeply in relief. That's when Zipp got an idea.
"Hey! You up there!" she called out. The pegasus stopped and noticed the two female pegasi picnicking below. Much to their relief, she didn't seem to recognize them.
"Yes?" she said as she came down and landed near them. Zipp handed her Pipp's phone.
"You mind coming down and taking a picture of me and my girlfriend, please?" Zipp requested.
"Oh, sure. No problem!" The pegasi said.
Zipp and Pipp kiss again just as the pegasus takes their photo. She gave it back to them afterwards.
"Here you go, ladies," she said.
"Thanks!" Zipp said before the pegasus flew back up into the sky.
"O.M. Gosh! I can't believe you did that!" Pipp exclaimed.
"Calm down! She clearly didn't care, did she?" Zipp pointed.
"No, you're right… Sorry, guess I'm getting too used to kissing in secret, so having other ponies seeing us kissing is a little…"
"Scary?"
"Yeah!"
"I know what you mean. Well, either way…"
Zipp pulled Pipp in for another kiss, sans photo. "I'm really enjoying myself with you," she expressed, staring lovingly into Pipp's eyes.
"Me too." Pipp said in an equally loving tone.
"Hmm… I wonder what we'd have to do to get somepony to take booty shots of both of us…?" Zipp wondered, though she didn't sound too serious.
"Zipp!" Pipp protested.
"Again, kidding!" Zipp laughed.
"I swear you are five years old." The little sister remarked.
"Aw, lighten up, sis." Zipp urged her baby sister and secret girlfriend. "Forgive me?"
Pipp looked her big sister in the eye, even though they had to hide their love and didn't have many places to act like a couple in, she still loved her sister more than anything. So forgiving her for her teasing and jokes wasn't hard in the slightest. "Always," she said. She then picked up a sandwich and offered it to Zipp. "Now say 'ah'."
Her sister smiled and opened her mouth wide. "Ah…"
Pipp moved the sandwich closer to her sister's mouth so that she could take a bite out of it. Some of the contents squirted out onto her face, though Zipp didn't seem to notice.
"Good?" Pipp inquired.
"Oh yeah, you've outdone yourself again, babe." Zipp replied before belching. She chucked, she blushed in embarrassment. "Sorry…"
Pipp giggled. "You know, normally I'd be disgusted by that, but now I actually find it cute," she confessed. "Falling in love with you has been good for me."
Her big sister smiled, touched by her younger sister's words. "Likewise."
Pipp finally noticed the bit of food on her sister's cheek just then. "Oh. Hold on."
The pink Pegasus leaned in closer to Zipp before licking the bit of food off her cheek in a slow and intimate manner.
"Pipp…" The white Pegasus responded slowly with rosy cheeks.
Her sister/lover licked her own lips with a smile. "Sorry, you had a bit of sandwich on your cheek," she said.
"Oh. Uh, thanks." Zipp replied. A large smirk appeared on her face. "You know… that kinda got me in the mood for some fun, up for it?"
Pipp smirked back. "I might. On one condition though."
"What's that?" Zipp questioned.
"I get to take the lead this time." Pipp replied.
"You, huh?" The big sister remarked with interest. "Think you can handle it?"
"Hey, anything you can do, I can too." Pipp boasted. "We're sisters after all."
"And way more." Zipp added with a smile
"Got that right, lover." Pipp said with a wink. "Alright, you know the drill; stand up, step forward and raise your butt!"
"Yes, ma'am." Zipp smiled as she stood up and stepped forward before sticking her rear up a little. "Like this?"
"Higher please." Pipp grinned naughtily while licking her lips.
As she raised her tail and moved it out of the way, Zipp adopted a pose similar to a downward dog or an animal ready to pounce. "Like this?" she asked with a suggestive smirk and tone.
The same look appeared on Pipp's face. "Oh yeah, totes like that,"
She approached her big sister/lover, stood on her hind legs as she placed her hooves on Zipp's flank before smacking her crotch with hers. Zipp moaned loudly as Pipp dry humped her rapidly, with Pipp moaning just as loud.
As soon Pipp stopped and pressed her crotch against Zipp's, the older sister grinds butt against her younger sister's private place, something Pipp responded to nicely.
Zipp grinder her butt against Pipp in slow, gentle circles. Pipp gasped and tightened her hold around Zipp. She quickly began to hump Zipp's behind almost frantically, grunting with each thrust. The two sisters panted heavily as they started to sweat a little.
Both of them gasped every time the most sensitive parts of their bodies collided and/rubbed together. Their gasps hall almost at the same time as the audible smacking sounds of their bodies made.
Pipp thrusted her lower body hard and fast and rubbed her crotch against Zipp's rump very slowly. She soon started to focus her efforts on humping her sister's butt. If they were on a bed, it'd be rocking and creaking.
Zipp panted and moaned as her legs started to shake. She closed her eyes and focused on the sensation her sister was giving to her as she pumped her hips into her.
"Hey… Zipp?" Pipp spoke up while still panting.
"Yeah…?" Zipp responded as she moaned.
"Do you… ever… think… about it?"
"About… what…? Ooh…"
"What's… next… for… us?"
"What's… Ah! Next?"
"You know, like…" Pipp began before pressing and slowly grinding her wet crotch against Zipp's clenched cheeks. "Maybe… the two of us… getting married?"
Zipp's eyes widened, and not just because she could feel her own sister's wet crotch squishing against her own. "Wha…?" she sputtered before chuckling. "Married? Really?"
"Yeah! Just imagine it; me as the blushing bride, and you as the dashing groom…" Pipp said, already imagining the scenario in her head and becoming even more aroused thanks to it. "Our honeymoon…"
"Oh wow…!" Zipp moaned, becoming just as aroused. The longer Pipp grinded against her, the clearer the image of her and Pipp's forbidden wedding became in her mind. She saw all their friends in attendance, their mother officiating it, her as the groom and her Pipp as the bride, just as Pipp herself said. Her rump quickly began to vibrate against Pipp's crotch.
"Ooh! Yes! That's it! Keep imagining it! Keep picturing yourself taking my hoof and marriage… and making me your bride!" Pipp commanded. Pleasure quickly ran through her entire body, making it shake as much as her sister's rub. The two were soon grinding their private parts together at a rapid pace. "Maybe… Maybe even make a family!"
"If there's a way, we'll do it, sis!" Zipp vowed.
"Yes!" Pipp moaned and panted while leaning forward to lick the back of her sister's neck and gently bite her ear while pounding her sister's rump rhythmically, all while being unaware of her fake cutie mark falling off and revealing her real one.
Zipp moaned just as loudly. "Oh… I'm so gonna marry you…"
"You'd better!" Pipp stated.
"I'll take care of you… Make you happy!" Zipp continued.
"You already do!" Pipp assured her. "And when we're married… you can stare at my butt all you want!"
"Yes!" Zipp howled.
Pipp started to pelvic thrust again, grunting each time. To anypony else, they looked like two bunnycorn's in heat, and almost as fast. Zipp cried out with pleasure as Pipp started to spank her a little before both of them finally hit their limit and climaxed. Both collapsed on the grass in unison, completely out of breath and sweaty all over.
Slowly, they turned their heads and stared into each other's eyes before laughing. Zipp helped her little sister/secret lover back onto her hooves then turned around. Before Pipp could respond, Zipp bowed forward, raised her rump into the air again and teasingly wiggled it at her sister.
Pipp giggled with rosy cheek before finally obliging and giving Zipp's butt a smooch this time.
Just as this happened, an unknown pony stuck a camera out of the bushes and took a picture of the obscene act before starting to post it online. It only took a minute or two before the pic started to go viral.
