Chapter 1
"I cannot believe I let you talk me into this."
"Aw, come on, Zipp! Just be open to the experience. Who knows? You might actually enjoy it."
The white tomboyish Pegasus princess named Zipp continued to frown as she got into the bubbling jacuzzi. Shortly after, her younger sister, Pipp Petal, got into the jacuzzi as well with a long and relaxed sigh. She rested against the edge of her side of the hot tub with half-open eyes, lowering herself deeper into the hot waters that were generating steam.
"Ah… You see, sis? Isn't this the best…?" Pipp remarked, completely relaxed. "Oh… it's like my stress is just melting away…"
"Uh-huh, good for you…" Zipp muttered.
"I'm telling you, Zipp. This, plus the massage afterwards, is just what you need." Pipp assured her older sister. "You've been so stressed by all your detective work, and literally all of my fans know how busy I've been with Mane Melody and the Pipsqueaks."
"Hence why a good old fashioned spa day is just what the two of us needed, I know. I remember that whole speech you gave me earlier." Zipp said almost tiredly.
"Which totally worked." Pipp said proudly.
"Pipp, I know you wanna help and I totally appreciate it. But you know spas aren't my thing, they never have been." Zipp reminded her.
"I know, believe me, I know." Pipp said, slightly annoyed. She managed to put on a smile though that seemed to surprise Zipp and briefly make her heart skip a beat for a moment. "But it means so much to me that you actually agreed to do this with me."
"Uh… sure." Zipp muttered, stunned.
"I mean, it's been, like, forever since it was just the two of us." Pipp commented. "Believe it or not I'd love to hear about all the detective work you've been doing. If you're willing to listen to me go on about what I've been up to, that is."
"Um, yeah, you're right. It has. So uh… not much happening with me, but uh… I see you've been uh… taking care of your mane lately." Zipp said, now beginning to get a little flustered.
"Why yes! Yes, I have. Thank you for noticing." Pipp beamed proudly with a mane flip. "Speaking of which, for a pony who doesn't like styling her mane, you sure do a good job of making yours look good."
"Oh, uh, thanks… I-I don't really use anything special. Just regular shampoo and conditioner." Zipp shrugged with a bashful smile.
"Well, it's totally working for you." Pipp stated with a wink.
Zipp could feel her face getting warmer, like her cheeks were gonna turn red at any moment. And for some reason, she started to get a strange, jittery feeling in the pit of her stomach that seemed to get stronger the more she stared at her sister.
She just couldn't figure out what it was or why she was feeling it. It didn't really dawn on her before now, but she could see just why Pip's fans thought she was so pretty. A cute face, pretty lashes, eyes one could get lost in, and the way both sweat and water rolled down her face and body was almost mesmerizing.
The older sister soon began to fan herself with her hoof as she gulped. "Whoo! Uh… I think… I think it's getting a little too hot for me," she said. "May-Maybe we should get out now?"
"Oh, but it's barely been five minutes!" Pipp whined. "Just a little longer, sis. Please?"
The younger princess gave her older sister the biggest pleading stare she could, and it made Zipp tremble where she sat.
"I…" she began to say before she became startled by a vibrating sound. Both sisters turned to the cellphone set near the jacuzzi.
"Oh! Sorry, that's probably Jazz. Hold on." Pipp said before she turned around and emerged partially from the hot tub to begin reaching for her phone, which was a bit of a struggle since it was out of reaching distance.
That's when it hit her. Zipp's jaw dropped as her wings became erect and her cheeks turned red. The moment she got a good look at her sister's backside.
Just from looking, ponies can see that Pipp was somewhat chunkier than Zipp and her friends, but they would never know how much unless they got a good look at her rear. It was both big and perfectly round, as well as more plush than any of the fancy cushions back in Zephyr Heights.
When they were fillies, Zipp used to tease Pipp about how much her bottom jiggled, nowadays Zipp kept her mouth shut about it but occasionally stared whenever Pipp danced on stage. So many times she's seen her younger sister wiggle her hips and flag her tail, so often that she's struggled to keep herself from drooling.
For a long time, she didn't know why this strange thrill ran through her body whenever she stared at her sister for too long, but now she finally realized what it was. It was something unnatural. Something that nopony should ever find out. Something she's tried to suppress.
And yet, for some reason, she found herself moving closer and closer to her unsuspecting little sister, eyes glued to her rump.
She kept wondering why she was getting so excited, she had seen Pipp's butt many times before and yet, it felt like it was drawing her in. It was just so round, and juicy and smelled so nice. A large part of her now just wanted to squeeze it, to lick it and kiss it.
Once she was inches away from her sister's bottom, Zipp bit her lower lip and struggled to keep herself from doing obscene things to her precious little sister.
Oblivious to the turmoil her big sister was going through, Pipp continued struggling to reach for her phone, even emerging a few more inches out of the tub. Eventually, her hoof made contact with her phone, making her smile. She looked at the screen to read the text Jazz sent her and laughed.
"Oh, that Jazz… So silly. Hey, sis, you should totally hear what Jazz said happened at Mane Melody." Pipp said. When she heard nothing but silence in response, she raised a brow in confusion. "Zipp? Are you even listening?"
Before she can say anything else, Pipp blushed as she let out a surprised squeak when she felt an alarming, pleasurable, and above all, wet, sensation that caused her wings to become erect and go pomf!
Slowly, she turned around and lowered her jaw as she stared with wide eyes at her older sister literally kissing her butt.
Not a second later, Pipp screamed at the top of her lungs. Zipp, who had her eyes closed at that moment, finally opened her eyes, saw what she was doing and pulled away to scream.
While Pipp fully emerged from the hot tub and scooted away quickly, Zipp went to the other side of the jacuzzi and pressed her back against it. The two royal sisters pant heavily, like they just flew to Zephyr Heights and back, their faces bright red and sweaty.
Zipp began to open her mouth to say something, despite the situation being beyond awkward, she knew she had to. If she didn't, the two of them wouldn't say anything and the uncomfortable silence between them would last forever.
Before she could though, Pipp beat her to it.
"Zipp," she said.
"Y-Yes?!" The white Pegasus responded quickly.
The younger sister quickly stood up. "What. In Equestria. Was that?!" Pipp demanded, her voice growing more and more incensed.
"Uh…" Zipp tried to say, but words seemed to fail her.
"You just put your lips on my bu… My bottom!" The younger princess exclaimed in a deeply offended and disgusted tone.
Zipp glanced away and, after a long pause, spoke again. "No, I didn't…"
"Yes, you did!" Pipp pointed out, annoyed.
"Ok! Ok! I did! I'm sorry! I'm so sorry!" Zipp apologized profusely.
"Why? Why?! Why would you do that?!" Pipp demanded. "Ugh! I think I'm gonna be sick…My own sister, taking advantage of me… Zipp, how could you?!"
"I… I'm so sorry! I… I don't know what happened! The second I got a good look at your rump and smelled how good you smelled, I just… I just lost control." Zipp tried to explain.
"I'm sorry, 'smelled good'?!" Pipp repeated incredulously. "You kissed my derriere because it smelled and looked nice?! Ponies don't just do that Zipp! Especially not when they're sisters!"
"I know! I know! Look, I get it. I lost my head. I made a huge mistake and all because I lost control." Zipp stated. "Let's just… forget this whole thing happened, ok? Please?"
"Ha! If only I could! But I can't! Do you have any idea how much of a mess I am right now?! Do you have any idea how wrong this is?!" Pipp demanded once again.
"Yes! Yes, I do! Of course I do!" Zipp insisted.
"Oh, really?" Pipp said, doubtfully. She turned slightly and showed the cheek Zipp kissed, traces of the kiss were still there. "Because the evidence suggests otherwise."
"Pipp…" Zipp started to say, but her sister turned to face her again.
"No! No, I'm not buying it!" The pink unicorn interrupted. "Tell me the truth, Zipp. You can't just assault me like that and then pretend like it was no big deal."
Zipp lowered her head. "You're right. You're right, it was a big deal…"
"No duh, it was!" Pipp cut in.
"And I really am sorry. I just… the truth is…" Zipp began to say. She struggled to say the next set of words as she gulped. Once she said them aloud, there'd be no turning back. Their relationship would be forever changed, it'd ruin their relationship as sisters forever. And yet, it felt like there was no going back anyway. As such, she inhaled and exhaled deeply before finally speaking. "I love you Pipp. Not just as a sister, but as more than that."
"What…?" Pipp responded softly and in shock. She turned to look at her sister directly.
"I'm sorry… I'm so sorry…" Zipp said, full of remorse. "I never meant to fall in love with you. I know you're still my sister and it's wrong for me to feel this way. But I can't help it!"
Pipp gained a sad look on her face as she listened to what her sister had to say, as well as rosy cheeks.
"I mean… you were always a pretty mare. Even as we were growing up I could see that, but I still saw you as just my adorable sister." The white Pegasus continued. "But somewhere along the way… maybe when you started performing and stuff… I started to get this weird feeling. Like butterflies in my stomach. Even though I knew it was wrong, I still felt attracted to you. I mean sure you can be a little full of yourself…"
"Hey!" Pipp protested.
"But you're also really kind and you obviously care a lot about your fans, just as much as you care about your friends and family. You'd do anything for them, and that's what I really love about you." Zipp confessed.
Touched, Pipp put a hoof on her heart. "Really?"
Zipp nodded. "Yeah. You also don't care if your… plumper, then most ponies."
"Hey, there's nothing wrong with a few curves." Pipp stated confidently.
The older sister smiled as she shook her head. "No, there isn't. And that's another thing; when you're on stage, looking so alive and happy, when you fly about and sometimes shake your hips… I just feel… hot… all over really," she added with a red face.
Pipp's face also became red as she looked back at her own hindquarters.
"So… you're attracted to my…?" she began, sounding a little weirded out.
"Butt? Yeah… to me that's… that's your best physical feature. Well… that and your adorable belly." Zipp complimented.
"Aw! You think my butt and belly are cute?" Pipp remarked, flattered and blushing.
"Absolutely!" Zipp nodded, now feeling good that she was getting it all out into the open. But then, the memory of what she did returned to her. "So much so that… when you pointed it at my face, when I got a whiff of an awesome smell coming from between their legs… I just… lost it."
"I'll say…" Pipp muttered.
The two sisters stared down at the floor, or at the water in Zipp's case, with sad expressions. Neither knew what to say next, only that they could never be sister's the same way they were before, now they had to figure out what kind of sisters they were going to be from now on.
Finally, Zipp spoke. "Pipp. I just want you to know that… I cherish the day you were born and when Mom introduced you. From the moment I saw you, I knew you were going to be an adorable little sister," she revealed in an affectionate tone that made Pipp smile and become misty eyed. "But like I said… lately, I've begun seeing you as more then a adorable little sister. The first time I saw you perform, my feelings for you intensified. I was further wowed when I saw you actually twerked a little…"
Pipp giggled. "Yeah… Mom told me never to do that again," she recalled. "Wasn't how a princess should dance apparently. Even though it was fun… Hey, what else ya like about me? Physically, for starters."
"Well, aside from your squishy butt and belly, I think your eyes are like two pretty emeralds." Zipp replied.
"Yes? And?" Pipp asked, expectantly.
"Whenever I look at you, I just want to stare into those emerald eyes while also caressing that squishy butt." Zipp smirked.
Pipp giggled again. "Ew. Sis…" she said, playfully.
"Sorry. I-I know you don't feel the same way, and-and that I'm disgusting for thinking this stuff… I just… thought you should know everything about how I feel. So I don't have any regrets." Zipp sighed. "You're just so special to me, and I have to admit… I'm a little envious about how well you handle our Mom."
The younger Pegasus laughed. "Barely," she smiled fondly.
"Still, you show the kind sensitively and kindness most ponies expect from royalty. More then I ever could." Zipp confessed. "I know that to you I'm just a disgusting, tasteless, perverted older sister… But part of me hoped that… if you happened to feel the same way that is… we could be really happy as two newborn foals prancing around. But instead I ruined it by taking advantage of you… You deserve better then that. Better then me. So… if you want… I could go back to Zephyr Heights and tell Mom what I did… she'll punish me but… at least the pony I love most will be happy."
Zipp sank further into the water, almost like she was trying to drown herself in the bubbly hot water, as well as her own sadness. She quickly sat up with wide eyes when Pipp suddenly got back into the tub.
"Happy? Zipp… how could I ever be truly happy… if you're not there by my side?" Pipp inquired, tenderly.
"Pipp…"
"While I'm still a little freaked by what you did, I didn't exactly… hate it, per say…"
"Really?"
"For real. It actually felt… Nice, for some reason."
Zipp blinked. "Wow, sis, you're a perv."
Pipp laughed and splashed Zipp a little. "Shut up!" she said. "Seriously though, I would never ask you to leave or tell Mom about what happened. I love you too much to lose you."
Zipp raised both her brows for a moment before smiling. She raised them again when Pipp suddenly moved closer to her until she was right in front of her.
"I only wish I had known earlier that you felt as strongly about me as I do about you." Pipp confessed.
Pipp's words shocked Zipp to the core. "What? What do you…mmph!" her words were cut off when Pipp suddenly leaned forward and pressed her lips against hers, connecting their muzzles in a tender but firm kiss, causing Zipp's cheeks to become pink.
She moved both her hooves to Zipp's shoulders as she pressed her body against her older sister's. While Pipp's eyes were closed, Zipp's were completely wide and ready to pop out.
Zipp struggled to free herself, but her feeble resistance proved useless since Pipp had her pinned against the edge of the jacuzzi.
As panic and confusion began to fill her, Zipp continued to try and escape. But since she couldn't go back, she decided to move forward instead and tried to overpower Pipp.
In response, Pipp moved Zipp up and over the edge so that her upper body was laying on the floor. With enough effort, Pipp got both of them out of the hot tub with Pipp's own body on top of her sister's. Pipp moved her hoofs from Zipp's shoulders to Zipp's own hooves, keeping her pinned while she squirmed around a little.
Finally, Pipp removed her lips from Zipp and opened her eyes to stare into Zipp's. In that brief moment, to Zipp's surprise, Pipp's eyes seemed to sparkle with love and affection. She wasn't reveling in the domination of her older sister or playing some cruel joke, instead all Zipp could see was all the warmth and affection Pipp had for her.
"Pipp…" Zipp said softly and stunned.
Before Zipp could say another word, Pipp closed her eyes and locked lips with her again. This time, Zipp stopped trying to struggle and gave into the kiss. Slowly, her pupils dilated before she closed them as well.
As Pipp's body also relaxes, both ponies could hear each other's heartbeats. As she listened to her sister's heartbeat, Zipp quickly noticed that it was beating as fast as her own.
Finally understanding how her sister feels, Zipp began to return her sister's kiss, pressing her lips against Pipp's with vigor she didn't know she had. All of her frustration, pent up lust and relief found their way into her kiss.
Their mouths opened a little to let their tongues touch each other briefly before they began exploring each other's mouths.
As Zipp moaned with pleasure, Pipp shuddered as well and deepened the kiss. Pressing her lips and body against Zipp's with renewed force. Meanwhile, as Pipp puts her hooves on her face, Zipp wrapped her free front legs around Pipp's back, completely lost in the haze of excitement and the rapid heartbeats.
Finally, the two pull away, creating a bridge of saliva between their lips. Both of them breathed heavily as they stared down at each other with half-open eyes.
"Pipp… Th-That was…" Zipp said, breathless.
Pipp smirked flirtatiously. "Spicy, right?" she inquired with a raised brow. "Come on, you can't tell me you didn't feel a little bit of heat and electricity just now."
"I…" Zipp began before being cut off.
"You were about to ask what I meant when I said I felt the same way, right? Well, I hope that answers your question." Pipp stated.
Zipp nodded. "Oh yeah, loud and clear…"
"Good! Because otherwise, I'd have to, like, go to way more drastic measures." Pipp said.
Now it was Zipp's turn to get all flirty as she smirked at Pipp. "Ooh, then maybe I should've answered differently then."
Pipp averted her gaze as she blushed. "Oh… You'd better be careful what you wish for! Or else you're gonna get it!" she warned her older sister. She finally let out a deep sigh. "Zipp… Believe it or not, I understand how you feel. I've been struggling with holding back my feelings for you too. Possibly even longer! And it's been totally eating me up inside."
"I… I never noticed." Zipp remarked, completely stunned.
"That's because I do such a good job of hiding it." Pipp boasted a little with a mane flick. "Still… It weighed me down. Every time I'm around you Zipp it feels like something's burning inside of me… It felt like it was cause me to announce how I feel about you for everypony to hear. I didn't think I could take it any longer. And then… you did what you did, and now… I can finally tell you everything. I'm so happy."
Zipp smiled at Pipp's smiling face. "Me too…" she expressed. A bad thought made her frown though. "Still… It's…"
"It's wrong, I know… But I think we both know that it's almost impossible to stop being in love." Pipp stated. "We don't choose who we love either."
"Yeah… but…" Zipp began before Pipp rose up a little and slowly turned herself around. As Zipp raised her head, her eyes bugged out and her cheeks turned red when she suddenly found herself up close and personal with her sister's butt, her tail raised and out of the way.
"Speaking of butts. You're still into this, right?" Pipp teased before she started talking in a sing-song voice. " Well, here you go! "
Zipp quickly started to sweat. "I-I-I don't know about this, sis. Let's not do…"
"Don't do what?" Pipp asked innocently before she to move her behind to and fro, making her plump butt cheeks jiggle, wobble and shake like a tight bowl of jello. "This?"
"I… I…" That was all Zipp could say and all with a nervous tone.
The younger sister quickly muffled Zipp by pressing her big soft globes into her face. She then began to move her patootie from side to side, firmly rubbing Zipp's face with her fanny.
"What was that, Zipp? Speak up! I can't hear you! " Pipp sang playfully.
Zipp tried to speak, but anything she said was muffled while Pipp rubbed her buns against her face a little harder.
Eventually, Pipp pulled her rump away from Zipp's face, allowing her to breathe, though she still kept it close.
"Pipp…" The older sister breathed.
"Well? Go on, butt kisser. Give my tushie some love." Pipp encouraged teasingly. "Never letting that go, by the way."
Feeling like they'd reached the point of no return, Zipp gave into her lust and started planting kisses all over her chubby sister's booty. Each peck sent shivers up and down Pipp's spine, as well Zipp's
The pinkish purple moaned with pleasure. "Oh… Yes! Oh, yes, Zipp! Lick my butt now! Lick my butt!"
Zipp obliged and started moving her wet tongue up and down the space between Pipp's rear legs and under her tail.
Pipp moaned louder and louder, her whole body trembling. She squeaked as Zipp wrapped her forelegs around her haunches to bury her face further into her crotch. As she let out a cry to the ceiling, she glanced down at Zipp's crotch below her and licked her lips.
"Thanks for the meal!" Pipp sang as she promptly lowered her head and started licking all over the space between her sister's legs.
The royal sisters quickly began licking in sync, their faces buried in each other's crotches.
Pipp raised her head with a gasp and an aroused moan before smiling. "Enjoying yourself, aren't we, sis? I can tell by how hard you're breathing through your nose. Ooh!" she said with a long squeal.
After another lick, Zipp moved her head back too and moaned with a sigh. "Yeah… back at ya…" she panted. "You're picking this up quick."
"I'm a fast learner." Pipp said proudly. "And I couldn't have asked for a better teacher. Care to show me more?"
"You bet. I know tons about stuff like this." Zipp revealed.
"Really?" Pipp remarked in surprise.
"It's not just science and detective books I read, you know." Zipp said with a wink.
Pipp blushed and grinned. "Ooh! Now I really do want you to show me more."
"Oo, well, aren't you a romantic?" Zipp teased.
"Says the pony who was mesmerized by my radiant rear end." Pipp teased back.
Zipp eyed Pipp's privates in front of her with interest. "Speaking of which," she began before sticking out her tongue and licking the area under her tongue.
"Yah! Aa, ah! Nya! D-Don't… lick me… so… Oh! You're tongue… going so far in…" Pipp moaned and cried out.
Zipp started to make similar noises and spread her rear legs out as wide as she could as Pipp licked the area between all over with her wet tongue.
Both of them dug their tongues in deep, then pulled them out and started licking and sucking each other passionately. Every time they did, shivers once again went up and down their spines.
This went on and on before they both let out cries at the top of their lungs.
Pipp sighed as she rolled off of Zipp and laid on her back beside her older sister. Both sisters pant heavily and out of breath, their cheeks rosy and eyes dewy. Both stared up at the ceiling like they were in a trance before big smiles appeared on their faces.
"That… was… in-credible!" Zipp expressed.
"Totes…!" Pipp added.
"I can't believe we were so scared to do this." Zipp remarked.
"I know, right? It, like, didn't feel weird at all!" Pipp commented. "It just felt… natural."
"So… What now?" Zipp wondered as she glanced at her sister.
The pink Pegasus spun around and laid on her side, as did Zipp, so that they were face to face. "I don't know… There's no going back from this." Pipp noted. "And we can't just pretend it didn't happen."
"That's for sure." Zipp agreed. "But you know… that's ok. I love you, that's all that matters. And if we're really careful… Maybe we can do this again."
"You'd be ok being in a relationship with your own sister?" Pipp inquired.
Zipp smiled and cupped Pipp's face with one of her hooves. "Of course. There's nopony else I'd rather be with."
Pipp smiled back. "Me neither…" she said lovingly. "Oh… I wish the others could know."
"But we can't tell them. They wouldn't understand, and I don't even wanna think about how Mom would react." Zipp expressed, cringing at the thought.
"I guess we could keep it a secret. Which shouldn't be a problem since we kept the fact that we couldn't fly for so long." Pipp pointed out. "And don't worry, I know I have a tendency to stream and blog everything for attention, but I'd never tell a soul about this."
Zipp nodded with a smile. "I know you won't."
Pipp smiled back before she and Zipp picked themselves up, staring into each other's eyes the whole time, especially when they were standing on their hooves and facing each other.
"So… that massage pony is probably waiting, up for it?" Pipp offered.
"With you? Any time." Zipp nodded and smiled. "And in exchange, I get to take you out on a date next Saturday."
Pipp widened her eyes in surprise. "A date?"
"Yep, just you, me, anywhere you wanna go." Zipp said.
Pipp almost cried with joy as she smiled at her older sister. "I'd like nothing more,"
The two sisters moved closer to each other, touching each other's faces with their hooves and locked lips for a brief moment this time.
"So, I guess that makes you both my sister and my girlfriend now." Pipp remarked.
"If you want me to be." Zipp shrugged with a smile.
"Uh, of course!" A beaming Pipp expressed like it was obvious.
"Ok! I'm your girlfriend/sister then!" Zipp declares.
"Great! Now come on, let's get massaged, and try not to stare at my butt the whole time." Pipp winked before turning around, then playfully brushed Zipp's face with her tail and walked ahead. Despite Pipp's light warning not to, Zipp's eyes were indeed glued to her sister's backside. She tried not to drool as Pipp's hips swayed in a sexy manner before Pipp stopped and turned around with a smile. "Stop it."
Zipp laughed and started to follow her little sister/girlfriend.
