Coming To Terms With The Monster Within

Celestia heard the sound of a loud moan as she rested her head down to sleep after a very long day. She had heard that many times in the past, though recently they had came few and far apart and at spontaneous times. The solar princess knew her sister was a screamer, but let her be damned to the ninth circle of Tartarus if it wasn’t a little annoying. At least it was cute. Celestia’s cheeks turned a bright shade of rose as she turned over and used her magic to adjust the pillow. Sounds like she’s alone, The Sun goddess thought to herself while frowning. She had all hopes of Luna getting busy with Nightmare as soon as possible.

“Luna will need to do this by herself.” Inky’s words echoed in Celestia’s head.

The princess’ face contorted to fit the deviously large grin plastered across her visage. “Says who?” Celestia, mischievous as ever, had come up with an idea that was crazy, yet could yield promising results. With a sudden burst of energy and a wave of her horn, she levitated a thick book out of the shelf and flipped to the first page. Her horn ignited as she lit the small candle to her side, shrouding the dark room in an orange glow. After a few seconds of searching, Celestia found exactly what she was looking for: Aphrodisiacs – lucky for her that the book was in alphabetical order. Her face contorted even further as she read through the preparations.

Ambient ticking of the clock on her wall caught her attention. It displayed a time that spawned a feeling of distraught in the pit of her stomach. Reluctantly, she marked the page with a large crimson feather, placed the book underneath the large mattress and blew out the candle before salvaging what she could of a nap before actually starting her day.

…

After the very uneventful daily grind, Celestia calmly made her way back to her room and informed the guards that she wished to be alone. They complied and left their station outside of her door, repositioning themselves at each ends of the long hallway. The alicorn princess quickly brushed up on the information detailing the process of the spell and, once she felt ready, began preparing. Lacking the necessary means of brewing a potion, Celestia resorted to the magical alternative.

As her eyes searched through the book, analyzing each and every single word, Celestia couldn’t help but let out a chuckle, which grew into an almost maniacal cackling and ended up dying down with a choke. It’s the least I can do to help, she thought. Guilt slowly began to ebb into her mind, forming second thoughts about the so-called plan she had thought up. Doing something like this to her sister felt wrong. It was a prank, in essence, but it had a good cause, she told herself.

But what if this backfires? What if Lulu get’s hurt? Celestia sighed a deep sigh, sinking down into her bed. What is the worst that could happen? Seconds passed by as she thought and nothing incredibly dangerous came to mind. Maybe I could… watch them. An image of her sister and Nightmare Moon covered in sweat, performing various actions and motions for one another forced Celestia to bite down hard on her lip, nearly drawing blood, enticing enough pain to keep her head steady. Just to make sure everything goes well, of course, she lied to herself. Upon imagining the large, jet-black mare so defenseless, begging to be relieved by her own sister’s hooves, or perhaps tongue, Celestia cried out, “Oh, me.”

After a frigid shower, Celestia returned to her room and readied herself. Once she had acquired a slice of cake, which was rather easy with an invisibility spell and teleportation spell, the anxious princess placed the dessert down and looked to the book to make certain that she had every detail of the spell memorized. Silent seconds of deep concentration passed as her horn glowed in a golden aura, spitting sparks and softly humming. The tasty treat before her glowed as it levitated up off of the small plate and then softly landed back down.

It looked no different than before. Did it work? Celestia grazed the corner of her hoof across the top of the frosting, closing her eyes as her sense of taste was being overwhelmed by incredible sweetness. “Mmm… good.” Celestia’s inner glutton urged her to eat the cake, though her common sense kept that part of her at bay. That is until, after many minutes, the aphrodisiac began to work its way into her blood stream, quickly rendering her a soaking wet mare with but one thing on her mind: sex. Celestia began to grind her hips against her forehoof, further enticing the incredible heat between her legs. Her tongue lolled out of her mouth as strands of saliva fell to the rug beneath her suddenly weak and shaking legs. “I, heh, guess I outdid myself,” she mumbled in between stifled squeaks, leaning into the rug beneath her, her alabaster plot exposed high in the air and regal visage scrunched against the ornate rug and hooves playing at her drooling folds.

The regal mare rolled about on the floor, twitching and writing, letting out soft moans of pleasure as her hooves played at her moist sex. Her fluids slowly ebbed and flowed down her thigh to her hooves and then onto the rug, reminding her that she was still in the parlor. On shaky hooves, she approached her bed and fell backwards into it, continuing her thrusting and humping, further soaking her hoof in feminine juices.

Heated minutes flew by until her hooves were no longer enough to sate the growing desire inside her. Celestia took a moment to catch her breath before turning onto her side and using her magic to open the drawer on the nightstand next to her bed. A smile formed across her muzzle upon locating the phallic shaped object she was searching for.

Contrary to her sister, Celestia preferred stallions to mares. In her humble opinion, nothing quite compared to the feeling of being filled by a long, stiff cock. Her mouth watered at the remembrance of the salty taste of a stallion’s essence. She sighed. That was something the self-pleasuring object couldn’t give her. It couldn’t give her the hot feeling of another pony’s sweaty body pressed against hers as he thrust his length deep into her tight, moist walls as she screams into the pillow as the feeling of his ever-quickening pace inside her sends her careening off the top of ecstasy and into a mind shattering climax.

Her hoof continued its gentle assault on her swollen entrance as she coated the member with her saliva, taking it to the back of her throat, having overcame her gag reflex centuries ago. She gasped for air as she inspected the fake erection, glistening and ready.

Celestia sang out in a chorus of squeaks as the slick member spreaded her nether lips, sending a shock of pleasure out from her loins. The alicorn cooed, resting her head against one of the many large pillows on her generously sized bed. Her magic took control of the member as she brought her hoof down to her nethers, slowly rubbing in circles against her engorged clit.

The princess closed her already half-lidded amethyst eyes, focusing solely on guiding the member deep inside her with magic and breathing. Her back arched as she let out a hot breath. Celestia really had to enjoy herself more often.

Nearing her climax, she gradually began commanding her magic to work faster; it promptly began pumping away obediently. A shriek of joy echoed in her room as her sensitive inner walls tightened around the fake erection, milking it for a seed it could not give. Celestia’s ears flattened against her head as she purred in delight, taking many long, heated moments to enjoy the electrical waves of warmth flowing over her entire body before slowly pulling the member out. Celestia’s neck fell backwards, her entire form spent and happy. Being a princess, she barely even got enough time for something as intrinsic as masturbation. Resultantly, she tended to have a lot of built up stress.

Celestia looked to her side, glancing towards the seemingly harmless slice of confectionary resting innocently on her desk among many documents and quills. It was hard to believe that a baked sweet was about to save her sister. The exhausted princess reluctantly decided that she hadn’t the energy to perform the necessary string of spells to put her plan into fruition. Reluctantly, Celestia used her waning magic to fix the icing on top of the cake before teleporting it into her refrigerator, where it would remain until it was time. With hooves behind her head underneath a pillow and body still soaked in sweat, Celestia allowed herself to drift off into a pleasant nap.

…

Celestia slowly walked through the dark void of dreams, her mind hard at work creating various scenarios to enjoy later while her body renewed itself for the day ahead. A mental blockage stopped her as she brought her hoof to a floating square displaying a large green field. It fell to the ground, silently shattering like glass.

“Celestia… it has been a while, my beloved sister.” Nightmare Moon said in an odd, almost sultry tone upon rising from the shattered thoughts in a bout of smoke.

“Indeed, it has. How have you been?” Celestia approached the jet-black mare, knowing that she was entirely safe in her dreams.

“I am well… you know, for being on the moon for one thousand years. No hard feelings, of course.”

“Of course,” Celestia agreed, noting Nightmare’s attitude and questioning her intentions. “I hope you do not mind my prying, but how have you managed to get into my dreams?”

“Explaining how I have gotten here is not the point of why I have visited you.” Nightmare stated blankly.

“Oh? Do you have a proposition? A motive?” Celestia’s brow rose as she spoke.

The dark mare shivered before taking a deep breath and beginning her spiel. “You see, Celestia, I grow weary; my form is getting weaker by the night and there is nothing I can do about it. I cannot maintain a physical body for extended periods of time. The bearers of the Elements of Harmony are underneath your hoof and at your disposal, entirely able to erase me once and for all should you act upon it. I know full well that I am at your mercy, Celestia.

Hitherto I had all intentions of fulfilling my one purpose in the life that Luna has given me, but I am no longer able to. With a recent, shall I say, confession, I have discovered that she truly no longer wants me. With that knowledge, I admit defeat. I am tired of all the fighting. I am tired of all the pain and grief I have caused. Most importantly, I am sorry, Celestia... I never meant to hurt you. I never meant to hurt Luna either, nor anypony else. All I wanted was to do was give Luna what she deserved and I got carried away. I let the power get to my head. I do not care any more; I have failed her.

All I wish for now is to go peacefully, but I need some assistance for that to happen.” Nightmare Moon took a deep breath before continuing. “What I am trying to ask is… could we put this all behind us with the night’s most sacred of rituals?”

Celestia stood in shocked awe, her mouth slightly open agape. It took strength to acknowledge failure like that, Celestia knew. The princess raised her hoof to Nightmare’s shoulder, resting it on the divot of her withers as she nuzzled her neck against Nightmare’s. She felt a heavy tear fall to her back as she slowly pulled away from the embrace. “Ritual? What does this entail, my dear?”

“It has… been a while since I have shared a… moment of intimacy with somepony.” Nightmare admitted, embarrassment red on her dark cheeks.

“You and me both…” Celestia murmured. “I am deeply sorry. Truly. I know I am to blame for that…”

“Before I am absorbed by Luna’s psyche, I wish to be intimate with somepony. I wish for that pony to be you, Celestia.”

“I am honored, but we have already made amends, my friend. You and Luna should do some talking. I am certain that you could –”

“Oh, no, Celestia, I do not think you understand – that was not a proposition – it was a demand.”

“Excuse me?” Celestia’s face twisted into a look of disgusted confusion as the millennia old gears in her mind grinded away for a few long seconds, quickly realizing what the dark mare had said. On the inside, Celestia beamed, tacitly deciding to play along with Nightmare’s fantasy without a second thought.

“Prepare for the best nightmare of your life, Celestia.” Nightmare Moon exclaimed as she brandished her glowing horn. Celestia fell to the ground back first, feigning struggle as dark magical restraints entangled her limbs and belly, splaying her out for Nightmare to do as she wished. The ‘helpless’ alicorn watched as Nightmare approached her, continuing with her acted toil, yanking at the glowing metal links.

“N – no! Please, don’t –“ Celestia cried, shaking her head about, as if putting all of her energy into her struggle.

“You are mine now, Celestia, and you will do as I say. Understood?” A whimper escaped Celestia’s lips as Nightmare held out her forehoof to her white snout, “Clean my hoof. I want to be able to see my own reflection.” she commanded. The demeaned princess opened her mouth and began obediently licking the black hoof, softly moaning while soaking it in her saliva. Her nethers grew wet, begging to be touched as her tongue danced through the thick fur. Nightmare cooed happily before she said, “Good girl. You will learn your new place in due time.”

Celestia looked up behind the hoof in her mouth. Upon noticing the dripping erection between Nightmare’s legs, she let out a stifled shriek. “Silence, my slave.” The black hoof was removed from Celestia’s mouth. Upon uttering a sound, Nightmare commanded, “Quiet! I did not say you could speak.”

The restraints slowly began loosening around Celestia. As the last one disappeared into nothingness, the princess’ alabaster white hooves flew to her needing feminine lips, eliciting a groan of pleasure from the princess. “Rise. To me, my minion.”

Celestia mustered up control of her body and stopped her hooves before reluctantly standing upright and slowly making her way to Nightmare; her mouth watered in anticipation. The jet-black alicorn sat down on her haunches, grasping her sizeable erection in her hoof. “Suck my cock.” Celestia’s lips wrapped around the wide head, her tongue trailed around Nightmare thick member as she bobbed her head up and down the pulsing rod. Celestia fought against gagging as Nightmare pressed her hoof down onto her head, forcing her length further down her throat.

Nightmare let out a pleased groan as she bottomed out, her hilt grazing against Celestia’s teeth. Slowly, Nightmare allowed Celestia to pull upwards. A string of saliva connected the princess to her mistress’ twitching and soaked erection. The alicorn princess was allowed few seconds to take in precious oxygen before having her head forced back down around her owner’s erection. Chains wrapped around Celestia’s hooves as she attempted to rub against her needing sex. Nightmare looked down disapprovingly. “You must learn some patience.” She spoke calmly, yet stern and demanding, never once faltering over her words. Gradually, Celestia managed to keep a pattern with her frantic slurping and sucking, making certain to lap up any precum that seeped out of the thick head.

“Stand.” The chains around Celestia’s hooves disintegrated, allowing her to act obediently. Nightmare exhaled through her nose as Celestia’s skilled mouth left her member, leaving it coated in thick saliva. “You will call me Mistress. Do you understand, Slave?”

“Yes, Mistress.” Celestia shook with anticipation as Nightmare mounted her, teasing the head against the princess’ moist folds. “Mistress, please… do not tease me.”

“You have been a good slave. A little bit impatient, however. We will work to fix that. I think a reward for your obedience is in order.” Nightmare’s hips bucked forward, pushing her length into Celestia’s neglected slit. Inch by inch, Celestia’s tight walls slowly began to be filled; each passing moment sent wave upon wave of pleasure coursing through both mare’s bodies. Nightmare slowly pulled back as her pelvis touched against the royal flank, dampening the fur around her crotch in feminine fluids.

The princess of the Sun let out a badly stifled moan as Nightmare pulled out, only to slam back into her; the head of her member tickling against Celestia’s cervix made her squeak in joy with her mouth open wide, tongue lolling about in pure, unadulterated pleasure. Black hooves kneaded the taut flesh against the side of Celestia’s flank, tantalizingly massaging her two orange Suns. As she let out another satisfactory groan, Nightmare arched her neck forward and latched onto Celestia’s sensitive ear, biting down hard on the soft flesh. This elicited a shriek of approval from the mare underneath her.

The dark mare exhaled sharply, letting go of her grip on the ear as she tried to keep her climax at bay while Celestia’s walls clenched down in orgasm, milking her member. Nightmare pressed on, albeit slower, pounding her length into the alabaster princess beneath her. The princess writhed as her legs shook - muscles grew weak as Nightmare thrust into her with reckless regard. As her second climax neared, Celestia pushed backwards while Nightmare pulled out.

“Patience is a virtue, my slave. Good things come to those who wait.” Celestia nodded weakly as her forelegs gave out, displaying her rear to Nightmare Moon. The dark alicorn grinned as she bit at the polychromatic tail flowing in a non-extant wind, painfully yanking the white body backwards several inches as she exposed Celestia’s tight, pink anus.

“N – not there. Please, Mistress.”

“Silence.”

Normally Celestia would’ve called that the line, but this was a dream – her physical body wouldn’t be hurt, and she had the opportunity to send Nightmare away any moment, but she decided against it. When would she get another opportunity like this? Anyways, she was so close…

“Relax.” Nightmare prodded the head of her member into Celestia’s tight hole, slowly easing into her. The regal mare bit her hoof as a stab of pain came from her rump, though it quickly melted away into unbelievable pleasure when Nightmare began thrusting deep into her. Her tongue lolled out on the ground as her face contorted to portray the incredible feeling that pushed her over into a second orgasm. Her pink slit leaking with the fluids of her climax, dripping down from her to the ground, landing with an audible plop.

Nightmare roared at the new, tight sensation, quickly nearing her own climax. She watched in awe as the flesh of the princess’ ass jiggled and bounced about with each powerful thrust she made into the princess. The dark alicorn couldn’t help but press the two large cheeks together as she continued shoving her length deep into the princess’ ass. It was an incredible sensation, such incredible tightness around her erection. Nightmare Moon lost herself in the circular motion the princess’ cutie marks made with each thrust she made.

The visual stimulation proved to be too much for Nightmare Moon. The dark mare pulled out as she came, shooting thick threads of milky seed onto Celestia’s back, matting her alabaster fur. Nightmare Moon collapsed backwards, breathing deep. Her eyes closed as a sickening crunch reverberated outwards from her ribcage. Her muscular chest caved inwards on both sides of her torso; the sound only continued as her body broke. The last of her to remain was her head, adorned with a large grin across her visage. That too caved in with a grotesque noise. She disincorporated into a thick starry cloud that dissipated into the darkness.

An exhausted three-tone laugh echoed in the darkness before Nightmare announced, “Thank you, Celestia. That was… fun.“ Celestia rose to her hooves moments later, confused and tired.

She is still alive? She lied? I… shouldn’t have been so gullible. The darkness quickly consumed the not-so-regal-any-more princess, leaving her to a dreamless rest. She awoke several hours later with sheets soaked in her feminine liquids and a small smile on her face. “What a dream...”
