A Learning Experience

Warning--this chapter is pointless.

Perhaps it was Luna’s natural curiosity that compelled her to wander the darkened halls of the castle. Perhaps it was the reports of strange grunting and squealing noises from the Guard that pushed her deep into the winding tunnels that lead deep below the foundations of the Castle. Perhaps it was both.

Whatever the reason, the Princess of the Night found herself lazily trotting down the twisting and turning corridors beneath the castle, casting forlorn, nostalgic glances at the stones around her. She paused for a moment and ran a hoof over the cold marble wall beside her, remembering the time long ago that this hallway had been a thoroughfare of important documents and secrets rather than a cobweb-gathering relic.

She sighed as a deep blue hoof traced a wobbly line over the wall. Perhaps she too was just like this hallway; old, forgotten. A relic. The thought tugged at her chest, made her spine tingle with the same icy chill that clung to the stone she touched.

The chill made her feel like she was back on the moon, shivering uselessly against the cold void of space. Silently watching the stars, waiting for the time when they would align and aid in her return so she could finally crush her impudent sister and take her rightful throne-

She inhaled sharply. Those awful, nagging thoughts about overthrowing her sister, though nothing more than harmless bits of the old Nightmare Moon still stubbornly clinging to her mind, still shook her. Could she really be that easily corrupted, bent to do the whim of an evil, malignant entity with nothing more than words?

“No.” A dark hoof stomped the floor weakly. “We are strong. We cannot be corrupted again.” The words, though comforting, failed to ease the anvil that seemed to rest on her heart. That doesn’t change the fact that we’re still just the other princess. We are just as worthless as the stone below us and did we just hear a moan?

Luna’s ears instantly perked up at the high-pitched squeal that emanated from far down the hall. Though distant, it was still clear enough for the alicorn to distinguish the owner of the voice.

“That sounds like our sister...” she murmured as she spurred her hooves into motion, trotting gingerly towards the source of the sound. She cringed every time her hoofbeats echoed off the alabaster marble around her, silently cursing her inability to walk quieter.

As she made her way down the hall the soft squeaks and yells became louder and more defined. She could definitely hear her sister’s voice, but soon she picked out another through the racket. One much higher, almost filly-like.

“Now what could that possibly be?” As she inched down the deserted corridor she spied a door built into the wall. It was ajar slightly, with a single beam of warm light shining out. Whoever was making all the racket was in that room.

Can’t be too loud... don’t want to alert whoever’s in there of our presence. As silently as a hulking alicorn goddess could, she tip-hoofed forward. She cringed at every muted step, silently cursing her size. If only we were four inches tall. Then we’d be able to get around without anypony noticing. She paused. Hey, that’s not a bad idea. Maybe we should look into shrinking spells-

“Oh Goddess that hurts!” The sound of her sister shrieking in pain instantly popped her thought bubble. Every hair on Luna’s body stood on end, and her wings flared. Is somepony hurting our sister? Her face contorted into pure rage at the very thought. How dare they try to hurt Celly? We will not let this atrocity stand! They’ll see justice at our powerful hooves!

Secrecy thrown to the wind, she dashed to the door and flung it open, striking a threatening pose with wings flared and teeth bared. “UNHAND OUR SISTER, HEATHEN SCUM, OR THOU SHALT FEEL THE WRATH OF OUR MIGHTY HOOFTICUFFS!”

Luna had no idea what to expect as she rushed into the room to defend her sister. She expected evil robots with lasers. She expected sword-wielding ninja griffons. She expected crazed renegades trying to overthrow the monarchy.

She didn’t expect her sister’s personal protege shivering in orgasmic pleasure as she spanked Celestia, whose face was awash in, among other things, ecstasy.

A deep silence shrouded the room like a lead curtain. The three ponies stared at each other for a long while, their faces masks of shock and confusion. Twilight’s tiny hoof was still frozen mid-spank above a suspiciously hoof-shaped red mark on Celestia’s flank. As it slowly dawned on Luna exactly what was going on, her nose scrunched up. “Tia... is your student spanking you?”

The Goddess of the Day opened her mouth to speak, but hesitated as she fought for the right words. Finally she managed to stammer, “Uh - yes. Yes she is.” A nervous grin accompanied her glowing blush.

“So then-”

“Lulu, it’s exactly what it looks like.”

“That’s what I was worried about.” Luna’s face morphed from surprise and confusion to frustration. She brought up a hoof and tried to rub away a growing headache. “Tia, you know how much trouble you’ll be in if the press finds out about - could you please get off of my sister Twilight Sparkle, you’re making me uncomfortable.”

The filly complied, leaving a slick trail as she dismounted the sovereign ruler of Equestria. The sight made Luna shudder. “Thank you. Celestia, this was very rash of you. In case you haven’t noticed, the public doesn’t exactly take kindly to ponies having... relations... with fillies.”

“Hey!” Said filly piped up, crossing her arms indignantly, “I’m a big mare! Princess said so!”

“Sure you are. Anywho, I’m very disappointed in you Tia. This is most unbecoming of you.”

Satisfied her point had hit home, she stepped back a bit and gave the room she stood in a quick once-over. Aside from the candyfloss-pink walls that seemed to glow like neon lights, the room was quite spartan. A single bed occupied the center of the floor with a small matching chest leaning against the wall opposite the doorway.

Unfortunately for the Night Princess, she was so busy observing the room (and squinting against the garish paint on the wall) that she hardly noticed her sister slither off the bed and make her way over to the door, shutting it and knocking the deadbolt into place. “Oh Lulu, you need to lighten up. Pull that stick out of your rump.”

The dark alicorn tried to roll her eyes, but they quickly shot open in surprise as she felt her sister’s hooves lift her tail up and rub against her rear. “Hmm, I can’t even see the stick. It must be really wedged in there.”

“Celestia!” Luna turned on her Royal Canterlot Voice, turning around to face her sister with a stare so furious it could curdle milk at 200 yards. “What in Equestria are you doing?”

The Goddess of the Day returned a love-drunk smile. “Oh, just trying to find that stick somepony must’ve shoved up your rump.” She kicked her sister playfully. “Lighten up, Lulu. There’s nothing wrong with two ponies expressing their mutual love through consensual acts of sexual intercourse. Plus,” she turned a devious wink at Twilight, “it feels awesome.”

Luna wanted to slap her sister right there. “This is not appropriate behavior for a princess! Why, instead of, pardon my language, fooling around with your student here, you could be doing something like sorting files, or filling out paperwork! Doesn’t that sound like fun?”

All she got was a smirk in reply. “Oh, dear sister, I believe you need to lighten up a little.” Celestia began circling Luna like a shark, eyeing her ravenously. “And you know what? I think I know just the way to do it.”

“I don’t like the sound of that...” The Night Goddess’s voice took on the slightest hint of curiosity. What on earth is Tia planning-

The alabaster alicorn suddenly turned on her hooves and presented herself to her sister, wiggling her rump in Luna’s face. “Lick it.”

Well, that doesn’t leave much to the imagination. “Good heavens! Get your plot out of my face!” She recoiled. “Don’t you know that’s incest?”

“It’s not incest if nopony says it’s incest.” To drive her point home she flicked her flowing tail in her sister’s face seductively. “Now hurry up. My plot’s starting to get cold.”

“That doesn’t even make sense! And forthermore, you really need to reconshiduhmmh mmm!” Luna’s rant was cut short as Celestia impatiently shoved her still-dripping slit right into her sister’s open mouth.

For a moment all Luna wanted to do was scream. Then brush her teeth for the next thousand years. Yet as she tried to will herself to get away from the incestuous whorse that her sister had become, it became harder and harder for her to really do anything other than marvel at the taste of her sister.

No! The rational side of her mind screamed to life. She’s our sister! This is wrong in so many different ways! Stop! Alas, the animalistic side of the princess had already taken the initiative, gently swirling her tongue around her sister’s dripping folds.

“Mhmm, that’s better.” Celestia sighed as the slow warmth of her sister spread through her body before turning her eyes to the bed. “Are you enjoying this, Twilight?” Her student had already taken the initiative, furiously rubbing her tiny clit and panting as she acknowledged her teacher with a frantic nod.

Meanwhile, Luna’s mind was in utter turmoil. Half of her screamed, You sick pervert! We must cease this immediately! What would our parents think of such a disgusting act? The other half expertly countered with; Yum, love juice. It went without saying that the latter was slowly winning control of her physical actions as she continued slurping greedily at the glorious Celestial marehood before her.

“Lulu, let’s move to the bed. We wouldn’t want to make my student feel left out, would we?” Celestia moved her rear just out of reach of her sister, gently leading her toward the plush mattress.

However, as she did the Night Princess took a single step back, a look of utter confusion on her face. “I-I shouldn’t do this.” The rational side of her had taken the upper hand and was slowly dragging her back from the ragged edges of her sex-induced trance.

“Hmm... maybe this will convince you?” Propping herself up on the bed, Celestia spun herself and her student around so that both their flanks were facing Luna, wiggling innocently as the two giggled to themselves.

The visual assault on Luna’s eyes quickly stole any cognitive thought she had left. The sight of two of the most amazing flanks she had ever seen just sitting there, waiting for her to take them pummeled her rational thought into submission. Wordlessly she stepped forward and licked each of the two slits, savoring the taste as the two distinct flavors melded in her mouth.

“That’s more like it.” A dark smile briefly replaced Celestia’s lustful stare as she reveled in her corruption of her sister. “Now service us.”

Luna wasted no time in complying, diving her muzzle between her sister’s legs. As she did she extended a deep blue hoof to Twilight’s plot and gently parted the filly’s delicate lips. She settled into a slow but steady rhythm, flicking her tongue up and down her sister’s slit and caressing the filly’s sex.

The room quickly filled with the impassioned moans of the princess and her student. They dared a quick glance at each other, their hazy eyes locking on each other. The duo’s thoughts became one as they instinctively leaned into each other and locked in a deep kiss.

“Lulu,” Celestia said, breaking the kiss to the dismay of her student, “get up here on the bed and rut me. I need it.” Nodding lazily the Night Princess shot onto the bed, dragging her sister with her by the scruff of her neck. Letting Celestia slump down underneath her, she gave her sister a brief once over before deciding on a course of action.

The younger alicorn dived in without hesitation, flicking her tongue along the length of her sister’s body and planting light kisses on her pristine coat. The tingling feel of a million tiny stars dancing over her body every time Luna kissed her drove Celestia to the ragged edge of insanity. Whenever Luna planted a quick peck on her exposed underside she let out a barely restrained, almost animalistic moan followed by a quick shiver.

The Goddess of the Day let a stray hoof trail down her belly and massage her marehood in a quick rocking motion. Luna, wanting the same treatment, let her hips drop so her sex was pressed against the other side of Celestia’s hoof. Whenever the white hoof moved, it sent both princesses reeling with another fresh jolt of pleasure.

Meanwhile, Celestia’s protege sat there on the edge of the bed, completely ignored by her teacher. She weakly rubbed herself to try and pass the time until she could once again join in on the fun, but it seemed that if she was going to get anything tonight she would have to take the initiative.

With a sigh she hopped onto her hooves and circled the intertwined princesses, looking for the best spot of entry. Deciding against just jumping on top of the two, she trotted behind them where she had a very clear view of both of their dripping slits outlined against their matted coats.

Wanting to contribute to the love-fest, she tentatively leaned in and flicked her tongue over her teacher’s slit. “Oh! Twilight, do that again!” Celestia wrapped her hind legs around her student’s head and pulled her into her sopping marehood. “You’ve learned well, my student. Now - ungh - try learning a little deeper.”

Anxious to please her teacher, Twilight nodded and continued swirling her tongue around Celestia’s marehood. When she needed to breathe, she simply angled her head up and continued the assault with a hoof, sending unceasing tsunamis of pleasure through the alabaster alicorn’s head.

Celestia soon grew tired of being on the bottom. Her sex-crazed mind craved control. She gave a final devious glance at her sister and her student before enveloping both in a magical aura and floating them above her head. “Tia? What are you doing?” protested Luna. “Put us down!”

“In a minute, Lulu. I just want to try something.” Dragging herself to her hooves Celestia repositioned herself in the middle of the bed, her hooves squishing under several puddles of suspicious origin. She effortlessly floated her partners into their new positions; Luna on her back spread-eagled in front of the solar deity and Twilight making up the caboose behind her, getting a perfect view of Celestia’s still leaking slit through her flowing tail.

“Dig in, Twilight.” The princess wiggled her rump teasingly. “Your princess commands you.” Before she could turn her attention to her sister, she felt the filly start back up with a hungry whimper. “Ah, that’s more like it. Now, Lulu,” she glanced at her exposed sister, “time to have some fun with you.”

Luna was almost afraid to find out what her infatuated sister had planned; with such an animalistic look on the solar sister’s face, she doubted anything good could possibly come from this situation. “Tia... what do you plan on doing, exactly?”

“Why you, of course.” Letting her head sink level with her sister’s crotch, she eyed the dark, matted fur around Luna’s delicate pink slit. Craving a quick taste, she dragged her tongue from base to clit in one motion, eliciting a shudder from Luna.

“Oh, trust me,” she said, casting another hungry look at her younger sister, “there’s more where that came from.” By this time Luna was getting really nervous. She had never seen her sister act this... passionate before. She was always the more reserved, quiet one, a counter to her own creativity and zeal.

“Uh - Tia? Maybe we should... stop. You’re scaring me.”

All she got in response was a deep, throaty chuckle. Her sister gave her a deranged grin, her pupils slowly contracting to mere pinpricks and her lips curling upward deviously. “Oh Lulu. I would’ve thought you’d want this! You’ve been feeling lonely, haven’t you? Ever since you got back from the moon you’ve been nothing but a mope. You feel like nopony loves you, like you’d be better off back on the moon?”

Luna nodded her head shamefully. “You want to feel loved again, to fill that awful void in your heart?” The younger alicorn nodded again, squeezing her eyes shut to keep any stray tears from falling. “Tell you what. I’d be more than happy to fill you up, if you know what I mean.”

With that Celestia angled her head down so she was looking at the slightly stained sheets. “Tia, what are you doing?” Luna’s voice was full of apprehension.

“Oh, you’ll see.” With another lustful smile the older princess began to move her head forward, probing her sister’s sex with her horn.

The instant her intentions became clear Luna recoiled. “Celestia, you can’t be serious. Don’t you know how... weird that is?”

Her apprehension only made Celestia shake her head a bit, using her horn to part her sister’s folds. “It may be weird, but it sure feels good.” She wasn’t lying - her horn was glowing now, encased in a faint aura of lust-powered magic. Every last touch sent a vibrating wave of satisfaction directly into the princess’s brain.

“Now, what do you say we get down to it?” Foreplay disregarded entirely, Celestia rocked forward, gently penetrating her sister with her shining horn. With every centimeter deeper that she pushed, her body rewarded her with an ever higher state of absolute bliss. A low moan escaped her lips as her now-slick appendage drove deeper and deeper.

The sudden entry made Luna cry out weakly and bite her hoof. She wanted to protest her older sister’s violation, but an immediate and indescribably warm feeling in her loins quieted her. As Celestia drove further and further into her, scraping her walls with the sides of her horn, the singular sense of being filled made her forget, however briefly, all the horrid pain and angst that welled up inside her. The despair was, for a moment, replaced by hormones and passion.

Tis better to forget. Now quit daydreaming. We’re about to get rutted by our sister.

“Tia... do it harder,” she managed to squeak.

Celestia responded by drawing out of her sister, hesitating a moment, then rocking forward and slamming herself into Luna as hard as she could. Both alicorns screamed in delight as an anvil of seething pleasure dropped on both of their minds.

Their brains fizzled. The duo’s movements became completely dominated by the pangs of quivering bliss that jolted them with every thrust. Each stroke of the celestial goddess detonated another bomb in her head. It felt like she was going to explode.

Yet she kept on going, the desire to hear her sister screaming her name, begging for her to keep going driving her on. She lifted her head a little so the base of her horn rubbed against Luna’s clit.

The simple action nearly caused the younger sister to pass out, so intense was the jackhammer of satisfaction that pounded her uncontrollably. This new position allowed Celestia to flick her tongue along Luna’s plot whenever she dove in, adding another wave of pulsing pleasure to the lunar princess’s addled mind.

“Luna... you know... what happens when a pony’s horn... gets pleasured like this... right?” Celestia managed between pants.

“M-magical d-d-disc-charge?” Luna was shaking too much to reply coherently.

The older princess nodded, dragging another moan out of her sister. “Exactly.” With this she propped herself up on her tip-hooves and picked up her pace. The dull ache of pressure next to her brain was about to explode, and she knew it. With single-minded ferocity she slammed into Luna over and over as her horn grew brighter and brighter, anticipating a massive magical release.

The light went unnoticed by Luna, too immobalized with quaking pleasure to bother looking down. The increased magical flow only pushed her closer to climax. “Tia, I’m c-cumming!” Luna’s shout only made her sister push faster, swelling her magic gland to the point of bursting.

All the pent up energy inside Luna finally exploded out in a wave of warm, sticky fluid that drenched Celestia’s face. Luna wailed and bit her hoof fiercely as she collapsed under the weight of a crushingly intense orgasm, her body spasming violently as she moaned uncontrollably.

The feeling of Luna’s inner walls latching onto her horn broke Celestia’s dam. Her eyes flashed white with magical energy, and her horn pulsed with layered power only a goddess as strong as she could summon. With a gasp she buried her horn into her fellow princess, losing herself to passion as magic literally shot out of her horn in warm, flowing waves.

As her magicgasm reached its peak, the same golden glow from her horn began to appear around Luna. Both were too enthralled in their own roiling seas of pleasure to notice as the aura grew and solidified, evening out into a harsh, metallic light.

For good measure Celestia pounded her magical appendage into the younger alicorn one last time. As she did the magical glow around Luna began to pulse wildly, trapping her in a seething bubble of pure magical energy.

With a massive flash and a boom that shook the entire mountain, Luna disappeared in a ball of magically-induced fire, disappearing out of the room as if she had never been there in the first place. The only sign of her earlier presence was the fluid that still soaked the bed sheets.

The remaining princess was finally coming down from the heights of ecstasy. “Wow... I don’t think I’ve let out that much magic since I last sent Luna to the moon.” Celestia turned to find a stunned Twilight Sparkle laying against the far wall; evidently the magical explosion had sent her careening into the stone siding like a ragdoll.

“Ow... princess, what the hay just happened to Luna?”

Only then did Celestia realize that her beloved sister had just been zapped from the room by her magical climax. “I’m not quite sure - oh, no.” The monarch dragged herself to her hooves and, lighting up her horn once more, teleported herself and Twilight out onto the royal balcony. Turning despondently to her half-dazed student, she muttered, “Twilight, look.”

The student scanned the sky, looking for any anomalies. “I don’t see anything.”

“Look at the moon.”

Twilight turned her gaze to the glowing lunar body. There, stamped into its crater-pocked surface was the image of a mare, suspiciously similar to one lunar princess. “Tell me you didn’t-”

“I’m afraid I did.”

Twilight half sighed, half giggled. The absolute absurdity of the situation made her want to laugh until she cried and hit herself over the head with a mallet at the same time. “What do we do now?”

“Well, we should probably go get her.”

“Yeah... can we do it one more time, first?”

Celestia grinned, tousling the hair on her protege’s head as a warm smile overtook her face. “I think that can be arranged. Now get that fillylicious flank of yours back to bed and do me.”
