A Princess' Proper Education

Elise awoke in a cold sweat from another terrible nightmare.  For the fourth time this week,  she tottered fearfully down the hallway towards her older sister's room in her nightgown,  the dimly-lit walls of Castle Krakenburg doing nothing to assuage her fears. For the coddled princess, a good night's sleep was one spent in Camilla's bed, nestled in her warm bosom while soft, strong hands stroked her face and held her tight, protecting her from the horrors of the dark.

Little did she know that she wouldn't be the only one sharing  her sister's bed that night. For on Thursday nights, after the other siblings had retired to their chambers, Corrin would slink across the hallway into Camilla's room and find her ready and waiting, eager to tie him up and fuck him senseless.

And so, when Elise opened the door a crack (despite her sister's insistence on knocking first) she saw her brother bound, gagged and blindfolded, with Camilla's strap-on fucking him relentlessly from behind.

She stifled a gasp, suddenly feeling like she was intruding on something private. As the precocious young princess of Nohr, Elise was privy to many of the castle's secrets, never receiving worse than a stern word from her father for snooping. And she had seen her siblings naked in the royal baths before, especially Camilla, with whom she often bathed. But seeing them like this - Camilla's face flushed and wearing an expression she hadn't seen before, and Corrin's throbbing cock glistening with pre-cum in the candlelight as he moaned delightedly into his gag - was something else entirely.

Elise watched them for a little while, heart pounding and a cupped hand muffling her breath.  Camilla's fake cock pounded mercilessly into their brother's rear, leaving his cock stiff and painfully neglected. It looked different to when she saw it in the bathhouse, Elise noted. Camilla fondled her ample breast with one hand, while the other held tightly onto Corrin's hips, only releasing to give him a vicious spanking. She punctuated her thrusts with dirty words she had told Elise to never, ever say, and received muffled sounds of pleasure in return. Camilla's voice was breathy from arousal and soft, slick noises emanated from her pussy as it rubbed against the leather harness.

A strange, unknown feeling began to permeate Elise's body as she ogled her siblings - an unfamiliar heat that spread through her body, up to her face and down between her legs. Her breathing grew ragged and heavy, and her heart pounded louder and faster as her secret place started to ache. Her lavender eyes widened in fear and excitement at these new sensations as her brother's moans reached their peak.

"Are you going to come, my dear?", Camilla asked, a seductive lilt to her voice. Thinking she had been discovered, Elise let out a gasp and opened the door wider, not knowing that the question was meant for her big brother. Camilla stopped mid-thrust at the noise, drawing an especially pained whine from Corrin, and turned to look at the intruder. Her expression softened from one of shock and contempt to one of concern when she saw her little sister's face, shameful and on the verge of tears.

"Elise~?"

Corrin turned his blindfolded face towards the door, then tensed up again as Camilla slowly withdrew her shaft, robbing him of the sweet release he craved. He lowered his hips to grind into the bedsheets, and received a harsh slap across the cheek. Camilla flipped him over and gave him another hard slap for good measure before addressing their sister.

"Come here, dear," she said, not bothering to cover herself, instead beckoning Elise into a hug. The younger princess leapt into Camilla's arms, bursting into tears as she nuzzled her bountiful chest. Elise's guilt melted away as she surrounded herself with her sister's warm, luscious flesh. Corrin could only struggle against his restraints and try not to think about the unbearable tension in his groin.

"I-I'm so sorry, Sister," Elise stammered, "I-I was just curious and -- and I was having nightmares again, and I didn't want to interrupt... and... and..." She looked up at her sister, with her face hot and flushed and an unmistakable desire in her eyes.

"Shh... There's nothing to worry about," Camilla said, with a trademark warm smile that instantly put her sister at ease. "Are you feeling okay?"

"I... I feel weird," Elise replied, softening her voice to a whisper, "in my... secret place."

Corrin half-coughed, half-choked.

Camilla ran her fingers through the girl's hair and slyly moved her other hand down towards her own dripping cunt. "Ah... it's only natural for a princess your age to start feeling these things," she explained. "It's an important part of becoming a big, tough princess like your big sis!"

She threw an arm around Corrin's shoulder in an unfittingly casual way. "Your brother and I will teach you all about it, if you'd like."

Camilla couldn't help but lick her lips seductively as she said that, and Elise nodded eagerly, the subtext lost on her. Corrin, on the other hand, was shocked.  His weekly incestuous trysts with Camilla were one thing, but Elise was only 1█ years old! His doubts quickly faded away, though, as his mind was clouded by the excruciating sensation in his dick, and he remained silent.
"You see, Elise, what you're feeling is called arousal," Camilla lectured, gauging her sister's reactions. "It's uncomfortable, but... it doesn't feel bad, does it? When grown-ups feel aroused, we do what Corrin and I were doing earlier - that's the "sex" Flora and Felicia are always talking about."

Elise squirmed in her seat at the foot of the bed. The heat in her nether regions was growing unbearable, and she couldn't stop breaking eye contact with Camilla to glance at her brother's rigid cock. It twitched and throbbed like a caged beast, clear fluid drooling from its tip.

"And when we can't find someone to have sex with, we, well..."

Camilla gestured downwards, no longer hiding her feverish masturbation. She stroked her clit intensely, spreading her legs to give Elise a better view and letting a drop of her arousal fall onto the bedsheets.

"Take your clothes off and do as I do," she commanded. The girl hurriedly complied, removing her nightgown and placing it atop the pile of her siblings' clothes. Her small, pink nipples began to harden as her flat chest was exposed to the cool night air. She then slipped her bloomers off, causing Camilla's eyes to widen with lust as a string of feminine juices trailed from them to her bare pussy. Elise pouted, wishing her sister would stop staring.

The sisters sat at opposite ends of the bed, legs opened wide, with their brother and his hard cock waiting patiently between them. The older girl spread her folds slightly, gesturing towards the swollen nub in between. "This is called the 'clitoris', dear," she explained, beginning to rub it in long, slow strokes. Elise followed suit, closing her eyes as she let new sensations flood her senses. Corrin let out another moan, shamelessly turned on by the thought of his little sister. He rubbed his thighs together, seeking just a little more stimulation to push him over the edge.

Sensing his discomfort, Camilla reached forward and held his cock lightly between her fingertips. Her touch alone was nearly enough to bring him to orgasm, and it took all of his might not to cry out.

"The peasant boys call this a lot of names: 'cock', 'dick', 'shaft'--" Camilla's voice rasped with hunger as she listed the names, " -- but it's really called the penis. Boys rub it when they're aroused, too."

Elise opened an eye to watch the lesson, still rubbing her clit in a comfortable rhythm.

Camilla opened herself wider, letting Elise see her intimate parts in their full glory. "When a boy and a girl have sex, he usually puts it in here - the vagina - and moves back and forth like I was doing earlier," she explained. "It looks like a tight squeeze, but don't worry - it'll fit ."

She paused and released her grip on Corrin's dick, denying him release once again. She continued: "But a princess should save herself for marriage! That means you need to have sex in other ways until then, okay?"

Elise nodded slowly, her mind in a trancelike state as her fingertips traced languid circles over her clitoris, watching her sister's lecture through half-lidded eyes.

"For example," Camilla suggested, "give your brother's dick a kiss for me." Elise snapped to attention and crept forward, toward Corrin's waiting cock. She looked up at her sister, whose fingers were now buried knuckle-deep inside herself, and awaited further instruction.

"Like so," she said, withdrawing her fingers from her snatch and bringing them to her lips, then showing her little sister how she sucked them clean. Elise, getting the gist of it, positioned her mouth above Corrin's expectant dick.

The touch of his little sister's warm breath on his cock was too much. Before her lips even touched him, his hips jerked upward and he finally came, groaning at the immense pleasure built up over hours of torture at Camilla's hands. The first spurt of cum splattered across Elise's face, the rest spilling into her mouth and throat as he rammed his cock further into the princess' mouth. Her eyes lit up at the taste, finding it wonderful, and she proceeded to suck him dry in search of more, slurping messily as he rode out his orgasm. Elise withdrew the spent member from her mouth with a soft, wet pop, and Corrin laid back, exhausted.
Camilla draped her arms around Elise from behind, pressing her enormous tits into her sister's back. She gave her a quick peck on the cheek and smiled broadly. "What you just gave your brother is what we call an 'orgasm' - it's like all the good feelings come out all at once! Come on, I'll show you how to have one yourself. Sit down over there, just like before," she gestured.

Camilla untied Corrin's wrists as their little sister moved into position and resumed touching herself. Wouldn't want him to miss such a special moment, after all. He promptly pulled off his gag and blindfold and took what felt like his first breath in days.

"Gods, Elise, that was amazing! I haven't cum like that in" -- he cut himself off, seeing that she was close.

Camilla knelt before her sister's pussy, lapping hungrily at her folds in between words of encouragement, tracing delicate lines with her tongue across the sensitive spots she'd had endless experience pleasuring. Her fingers were once again plunged deep inside herself, trying to wring out her own climax as Elise's fingers danced across her clit.

Not nearly emptied after just one orgasm, Corrin's shaft quickly stood back at attention, ready to go another round. Taking advantage of her diversion, he grabbed Camilla's hips and forced his newly hardened dick into her tight asshole. He knew she would punish him later, but he was too consumed by lust to care. The elder sister let out a cry of pain at the sudden intrusion, quickly giving way to howls of pleasure as Corrin began to thrust his hips. The tight, hot friction of her inner walls drew his cock in and squeezed with a vicelike grip, threatening to bring him to his peak again so quickly.

Elise could feel a sublime pleasure swelling in the depths of her core. Between her sister's skilled tongue, the heady scent of her brother's semen on her body, and her own impassioned masturbation, she could feel herself coming undone, a delightful release on its way after ages of tortuous stimulation. At that moment, she understood the primal desire fueling her brother's moans.
Corrin picked up his pace, pounding his sister's ass with reckless abandon. Camilla groaned sensually into the pussy before her, pushing Elise to her breaking point. The young girl, soon to be a woman, opened an eye to meet her sister's gaze, and posed one final question.

"Hey... Sister."

"Mm?"

"When you said I -ah- ought to save myself for marriage... what does that mean, exactly?"

Camilla furrowed her brow, wondering why she would bring that up now. She knew the truth, but Elise was far too young to concern herself with such things.

"My dear, it means... that you should save your special place for the one you love."

Elise wrenched her eyes shut, chest heaving as she approached her climax.

"Well... -ah!- I love YOU, Sister, don't I?"

Camilla practically gushed at those words. She crept up and pulled her sister into a deep kiss, pressing her breasts against Elise's chest, their nipples rubbing against one another. Corrin, driven wild by the sight before him, redoubled the pace of his thrusts, as Camilla sank one finger, then another, into her sister's virgin entrance, and found the sensitive spot deep inside.

Elise felt an intense sensation of fullness as her sister's loving touch pressed against her deepest place, and then an indescribable feeling of release as she came undone, her first orgasm coursing through her body like lightning. Her breath hitched in her throat as her skin became electrified and her slick inner walls clenched around her sister's fingers, screaming her lover's name as she became lost in a sea of sexual bliss.

She came down from her high to see her siblings locked in a lover's embrace, Camilla screaming into her little brother's mouth as she reached her own climax, squirting messily onto the sheets. Not long after, Corrin came again, finishing inside Camilla, filling her asshole with his seed.

"How was it?", he asked as he came to his senses. But there came no reply, for dear Elise had fallen into a deep, restful sleep in her sister's arms, sweet dreams filling her head for the first time in weeks. He gave them both a kiss on each cheek and tiptoed back to his room, with a warmer, fuzzier feeling than usual.
