"So, what was so exciting that you had to drag me all the way out to Ponyville to show me, sis?" Terramar asked curiously as he flew with his sister away from the train station. "This isn't exactly a short trip, you know?"
"I know, I know. Sorry," Silverstream apologized. "But you've got to see what they have here! You won't belive it!"
"Alright, well lead the way Stream. I just hope whatever it is is worth it," Terramar grumbled as he followed behind her.
The two flew in silence -- well silence besides Silverstream's excited urging of him to fly faster -- toward a large forest growing beside the town. If Terramar recalled the little bit of Equestrian geography that he knew, that was the Everfree Forest. The place was apparently pretty dangerous if he remembered correctly, but he trusted that Silverstream wasn't leading him anywhere too risky. She could be a little scatterbrained, but she wasn't stupid.
Eventually an old, ancient looking palace came into sight. Silverstream seemed to be flying straight toward it, so Terramar assumed this was where she was leading him. His interest piqued as he approached it. He could definitely imagine something cool being hidden away in such a historical looking place. Maybe some long-lost artifact or secret history that Silverstream had stumbled upon in her studies. He couldn't wait to find out.
The two siblings landed together in front of the castle. Silverstream was practically bouncing as she led him to the entrance way. An imposing set of double doors stood ominously before them, silent sentries standing guard atop an impressive set of stone stairs, protecting whatever secrets this castle had to explore.
"Look!" Silverstream exclaimed, pointing in front of them toward the castle. "Aren't they awesome?"
"Sure, they're pretty imposing doors, sis," Terramar agreed. "So, are we heading in or what?"
"Not the doors, silly," Silverstream chided him. "Look at what's in front of them!"
"Umm, it's a flight of stai-" Terramar began, sounding a little confused.
"It's a flight of stairs!" Silverstream parroted his thought, sounding super excited for some strange reason.
"Huh, yeah?" Terramar prodded, expecting more.
Silverstream didn't say anything more though. She was just staring expectantly at him, appearing to vibrate with giddy energy as she watched Terramar's expression. When he didn't seem to match her excitement, her exuberant expression fell a bit. Terramar felt a little bad for obviously not reacting the way his sister expected, but he was kind of at a loss for what he was supposed to be getting excited for.
"Come on, Terramar. They're stairs!" Silverstream tried again. "Have you ever seen anything like them?"
"Yes?" Terramar responded hesitantly. "There was literally a set of stairs at the train station leading off the platform. We walked down them together. Besides, we have them everywhere back home, don't we?"
"What? We do?" Silverstream replied, now sounding just as confused as Terramar felt. "I don't remember any stairs underwater."
"I mean on Mount Aris," Terramar stated. "It's a mountain, sis. Of course there's stairs all over the place. How do you not remember seeing them?"
"Oh, well, I didn't really get to spend much time up on land before mom volunteered me to come here to Ponyville," Silverstream reflected. "I guess I never got a chance to explore around the place."
"Well, I guess that makes sense," Terramar admitted, "but why did we have to fly all the way out here to see them? There were stairs all over Ponyville."
"Well, yeah, but you know what else were all over Ponyville?" Silverstream asked.
"What?" asked Terramar.
"Ponies," Silverstream answered simply. "And ponies have just as many eyes as hippogriffs, you know. But out here..."
"...there's no other creatures to see us," Terramar finished her thought with a growing grin. Suddenly he understood why his sister had flown him all the way out here in the wilderness.
"That's right, bro," Silverstream's voice had suddenly dropped to a more sultry tone, as she walked closer to him. "It's just you, me, and this set of stairs."
She pounced on him as soon as she finished speaking, knocking him back to the ground as his sister now straddled him. The two siblings locked beaks together as they reveled in their first opportunity to taste each other in months. Their wings unfolded and wrapped around one another as their tongues wrestled in their mouths. Needful moans full of lust emitted from them both as their beaks clacked together. Terramar felt his erection hardening rapidly, rubbing against his sister's wet mound as they kissed. Gods, he had missed this.
When at last their kiss broke apart, Terramar took a moment simply staring up into the eyes of his beautiful sister, reveling in the feel of her touch once again against him. She looked right back down on him, a needy grin etched across her beak.
"Feels like you missed me, Terramar," Silverstream teased as she ground her warm slit against his throbbing erection. "Why don't you take a seat over on those stairs, and let your big sister show you how much she missed you?"
"You know you're only an hour older than me," Terramar grumbled as he stood up and made his way to Silverstream's stairs.
"And that hour makes me the big sister, dummy," Silverstream teased as Terramar sat his rump on the second step up. "Now, do you really want to have this argument again, or do you want to be a good little brother and let your older sister suck your cock?"
"Well, when you put it that way..." Terramar mused, "I guess I'll be a good little brother and take option two."
"Thought ya would!" Silverstream laughed as she ruffled a claw through his plumage. As she knelt down between his legs and prepared to take him into her beak, Terramar wondered to himself how many times they had had this same argument. Somewhere early in their hook-ups it had become almost a tradition, but he was unable to pinpoint exactly when.
The two siblings had been fooling around with each other for years now, ever since they had discovered the difference in their parts while playing together. Of course, back then it was mostly limited to exploring each other with fins and flippers. It had taken them a few years to really learn about sex and all the various ways two creatures could play with one another.
Not that Silverstream and Terramar were allowed to play in such ways growing up. He still remembered the first time their father had swam in on them grinding against each other in Silverstream's room. He had been pretty upset, but fairly understanding too. He had been relieved to learn that there had not been any penetration between the siblings up to that point, and had launched into a long, boring lecture about how siblings shouldn't do such things with one another, and that they should save such games for when they grew older anyway.
Ironically, the only part of his speech that either sibling really paid any attention to was the part about penetration. The next time they were able to slip away together -- now taking care to hide themselves better in out of the way coral reefs and tidal caves -- they had experimented with the idea. Silverstream had not been a fan of the first hole Terramar had attempted to penetrate, but the second try proved to be the charm and they had sex together for the first time. It had felt wonderful to make love to his sister like that, and neither creature had ever looked back as they endeavored to do it as often as possible over the next few years.
They had explored every possible way two seaponies could make love in the ensuing years. There was no part of either sibling that the other hadn't explored with fin, flipper, tongue, and -- at least in Terramar's case -- dick. Silverstream had even warmed up to anal after a while, though it still wasn't exactly a favorite activity of hers.
Once the Storm King had been defeated and the seaponies were allowed to leave the sea and retake their hippogriff forms, Silverstream and Terramar had been thrilled. Now they each had a whole new body for the other to explore, and many days were spent flying off to far-distant cloud-banks and having sex. Terramar suspected that the reason his parents had been so eager to send Silverstream away to this new school out in Ponyville was that they were beginning to grow suspicious of how often their children were 'practicing flying' with each other. They probably felt that separating the two of them was the easiest way to put an end to anything sexual happening between the siblings.
But, now here they were alone, with no one around for miles to disturb their reunion. And now his sister's beak was once again descending down toward his cock, eager to take him inside of her mouth and taste Terramar again. He leaned back on the stairs as Silverstream's tongue began to lap eagerly against him, slurping around his member as she soaked it with her spit.
Once she had slathered saliva all around his member, she moved to take him inside her beak. Terramar moaned as he felt the familiar damp warmth of his sister's mouth engulf him. He ran his talons through her head-feathers as she bobbed up and down on his length, her tongue dragging all around him as she sucked him off. Silverstream began to purr slightly as she swallowed him down her throat, the vibrations serving to increase his pleasure. Her wings joined in the effort, softly tickling his balls and anus with her feathers.
"Oh skies above, Silver, how are you so good at this?" Terramar asked, trying to distract himself so he wouldn't shoot off too soon. "I mean, your mouth's always felt nice, but this is a whole new level."
"Practice," she replied, lifting her mouth off her brother's dick and stroking it gently with a talon as she answered. "I've met a whole bunch of new friends at the School of Friendship, and the boys are always happy to let me practice sucking their dicks if I ask."
"Well, all that practice is paying off, sis." Terramar complimented her. "I'm not going to last much longer."
"Oh! Well, in that case let me shut up and get you back inside my mouth. Wouldn't want all that tasty cum going to waste, would we?" Silverstream asked, before swallowing Terramar back down her throat. Terramar placed a talon on the back of his sister's head, and gently but firmly pushed her further down his length. Silverstream did her best not to gag on him as she continued to suck and lick his cock. It wouldn't be much longer now before she received her tasty reward, she knew.
Terramar moaned loudly as he felt his orgasm approaching. The first shot of his seed fired down Silverstream's throat. His sister pulled back slightly to receive the rest of his load, so that only the tip of his cock was held in her beak. She wanted to taste that yummy cum before swallowing it, after all. Terramar shot off several more spurts of cum, his sister collecting all of it inside her mouth, swishing it around on her tongue as she savored the taste.
When she had finished enjoying her treat, she opened her beak to show Terramar the cum collected in her mouth, before making a show of swallowing it and showing him again her empty mouth. Terramar rewarded her with a kiss, tongues again melding together as he did his best to ignore the flavor of his seed on hers. When they broke apart, Silverstream was smiling back at him with a naughty grin.
"Ready for the main event, Terra?" she asked, stroking his length with a wing to get him hard again.
"Any time, Silver. But are you sure you don't want me to return the favor first?" Terramar asked. He was eager to fuck his sister again after so long apart, but he felt it would be neglectful if he didn't at least ask to eat her out first.
"Trust me, I'm more than wet and horny enough to skip that part," Silverstream reassured him. "All you need to do is mount up and fuck your big sister, okay?"
"Definitely okay!" Terramar replied enthusiastically as he began to approach his sister on the stairs.
"Besides, you've never been particularly good at giving oral anyway," Silverstream mentioned off-handily.
"Yeah, I -- wait, what?" Terramar asked indignantly.
Silverstream ignored her brother's reply and began to position herself to take his dick. Time to have some more fun with these stairs. She placed her talons on the ground at the base of the stairs, and walked her hind-legs up to the third step, so that she was positioned at a diagonal slant facing down toward the ground. She wiggled her butt at her brother invitingly.
"You gonna mount this, or do I have to take care of myself again?" she teased him.
"Ugh. One time I fell asleep before you came, and I'm never going to hear the end of it, am I?" Terramar asked with feigned frustration as he positioned himself behind her.
"Nope," Silverstream replied. "Those are the rules. A mare never lets her partner forget."
"Whatever. Hey, um, are you sure about this position, by the way? Aren't we going to end up face-planting the dirt at this angle?" Terramar asked with mild concern before mounting her.
"Hmm? Oh, yeah, it's fine," Silverstream reassured him. "Don't worry, it's not that steep an incline, but the angle is just right for a nice, deep dicking. Like I said earlier, stairs are awesome!"
Terramar just shrugged. "If you say so, sis," he said as he grabbed her flanks in his talons. Raising himself up onto his hind legs, he rubbed his cock against the wet lips of his sister's pussy. "Wow, you weren't kidding about being wet back here. I think we've done it as seaponies with less moisture involved."
"Hmmm, then stop teasing me and just fuck me!" Silverstream begged as she felt the tip of her brother's cock at her entrance.
Terramar happily followed his sister's directions, slowly pushing himself between her lips and inside the damp warmth of her pussy. The siblings moaned as they melded together. Terramar's cock was surrounded by the silky tightness of Silverstream's depths. He pushed himself all the way inside of her, fur tickling against his balls as he paused a moment to savor the feeling of his entire cock being engulfed by his sister.
Terramar began to fuck her, thrusting himself in and out of her tight folds. Silverstream's talons dug into the dirt beneath them as she braced herself against her brother's rutting. Their positioning meant his dick was able to plow deeper than usual inside of her, pounding against the walls of her cervix with the flat head of his cock. His balls slapped against her teats as he fucked her, the loud thwapping sound cutting through the silent clearing where they were making love.
"Wow Silver, I swear you're even tighter than I remember," Terramar stated between grunts as he plowed into his sister.
"Its 'cause you're not used to doing me at this angle. --Oh skies yes!-- I'm telling ya, Terra, these stairs do wonders," she explained even as she shouted her pleasure.
"Unf. Well I guess they do have their charm," he conceded, before slapping his sister's tight ass with a talon. "Just make sure you don't slip and send us both tumbling."
"Aww, but that --oh yes-- that just adds to the excitement," Silverstream claimed.
"Fucking you is exciting enough for me, sis," Terramar assured her. "Now, shut up for a minute and let me rut you proper."
No more words were exchanged as the two hippogriffs lost themselves in the pleasure of each other's bodies. The once silent clearing in front of the castle was now filled with the sounds of their love making. Wet, loud, and primal, the two fucked like wild animals as they attempted to make up for time lost apart. Suddenly, Silverstream let out a surprised squawk as she felt one of her brother's talons invading her ass.
"Hey!" she shouted as she glared at her brother over her shoulder. "You could at least ask before sticking something back there!"
"Aww, you know you'd just say no if I asked," Terramar replied teasingly, pausing his thrusts but still wriggling his talon around in her ass. "You never could admit how much you love when I play with your butt."
"I do not!" Silverstream replied with a huff, even as she clenched her anus around the invading digit.
"Oh, then I guess I should pull it out, huh?" Terramar teased, slowly withdrawing the talon from inside the warm cavity of his sister's behind.
"No!" Silverstream yelled, a little quicker and louder than she might have intended. "I mean... since you're already in there..."
"Well, if you insist," Terramar complied, slowly pushing his talon back inside her. He began to pump the digit back and forth in her rump. "I might even have something else to stick in there later, if you're up to it." he suggested, grinding his cock against her pussy to emphasize what part of him he meant.
That earned him a playful smack from one of Silverstream's wings.
"Don't push your luck back there, buster," she stated with mock indignation. "Just enjoy the juicy hippogriff pussy you're getting to plow, and get back to work.
"Fine," Terramar sighed in defeat.
He started to fuck Silverstream again, making an effort to coordinate the thrusts of his cock with his talon. As he plunged into her sopping cunt with his dick, he withdrew his talon from the depths of her butt. As he pulled out of her pussy, his talon once again pierced the tight walls of her anus. Back and forth he worked her two holes, causing her to moan out with obvious pleasure. Her moans began to get quicker and louder, and Terramar felt her clenching around both his invading tools. Silverstream let out a loud screech as she came, squirting out around him.
Terramar pulled out of his sister as she came down from her orgasm. He watched her for a moment with a warm smile as she caught her breath before addressing her. "Hey Silver, mind trying another position before I finish inside of you?"
"Sure," Silverstream stated, before her eyes narrowed in suspicion. "Just so long as it doesn't involve anal," she quickly added.
"Nah, nah, I got the message on that," Terramar reassured her. "I was just wondering if you wouldn't mind turning around on the steps so that I'm thrusting up into you?"
"Oh, sure. Like this?" Silverstream asked as she repositioned herself, her hindlegs now planted on the ground and her body stretched upon the stairs.
"Yeah, exactly," Terramar replied as he moved behind her and prepared to once again mount his sister. "Just raise your rump a bit and-- yeah, just like that. Perfect."
Terramar slid his cock back inside Silverstream's pussy, now at an angle where he didn't have to worry about tumbling to the ground if he thrust too hard. Silverstream let out a gasp of surprise at the increased force of Terramar's thrusts. No longer needing to worry about bringing his sister to climax, Terramar focused solely on achieving his own orgasm and filling her up with his seed. He didn't care about rhythm or pace or anything like that. He was just straight fucking her, primal instinct guiding his cock in and out of her wet hole. Faster and faster he pounded up into her. Silverstream simply let herself bounce on his cock as she enjoyed the rough fucking her brother was providing her.
It only took a few minutes of fucking at that pace before Terramar felt himself ready to cum again. He shoved his cock as deeply into Silverstream as he could, gripping her flanks and pulling her toward him. His seed fired into Silverstream's womb, pumping shot after shot of his love deep into her. The two siblings collapsed upon the stairs once he was finished, Terramar's softening cock still buried inside of his sister as his cum slowly oozed out of her and onto the steps. As the two rested from their rutting, entwined and connected in a loving embrace, Terramar had to admit that Silverstream had been right. Stairs could be pretty awesome.
"And that's how I spent my spring break," Silverstream stated proudly as she finished her report and returned to her seat. The rest of the class stared at her in various states of disbelief. Among her friends who shared class with her, Gallus was clearly doing his best not to crack up laughing, Ocellus was blushing deeply, and Sandbar was doing a very poor job of hiding the way his eyes kept drifting toward her rump.
"Silverstream, darling. You do know this was supposed to be a report about something that you learned while on break, right?" Professor Rarity inquired hesitantly.
"Yeah, of course professor!" Silverstream exclaimed from her seat. "I learned that stairs are even more awesome than I thought!"
Author's Note
This was originally going to be an entry for the Wincest Winter of Worldbuilding Contest way back in December, but I ran out of time and didn't finish it before the deadline. I'd hate to let it go to waste though, so I figured I might as well salvage something out of it. Can't let all that sexy hippogriff incest go to waste, now can we?
Hope you enjoyed the fic.
