Evening's little Secret, Night's favorite Time.

I kept my mouth shut after that as she finally lead me through the mysterious door that wasn't a sex dungeon as she claimed, but a communal room for her and her followers. Until I could actually see the room, I didn't press the issue as my sides still hurt from her displeasure, but now my training excuses will hold more credibility back in Canterlot.

Luna was more critical of my 'outings', and while never directly pressing to learn more of them, there were at least three distinct moments I swore she'd tried following me- from a distance of course. I'm not sure if she really did try, but the circumstances were odd enough, and she was the only pony that could pull it off which left me paranoid for a couple months during the transition into Fall. I did eventually inform Nighty of this strange, but valid concern one night, and I shouldn't have been too surprised by her response.

"Let that whorse of a pony arrive then! We shall show that mare once again how her weakness persists!

I found that declaration more amusing than anything even if she was sincere, and for that was a little flattered as well. Still, I suggested we not talk about the Princesses that way if at all possible, and after exchanging some words (thankfully that was all) she relented her claim, but still held her position on Luna's actions.

"We derive from a time of absolute rule dear Dusk Shine, of a belief the word of a princess is truth. Your own actions, and tellings of the princess suggest this is no longer true for you, but my sisters will remember it. There is no doubt they will remember. For it is they themselves who wielded this power in the open as a reminder to the populace and nobles which pony was the sovereign. Our memories are not our own, but will serve a great purpose: Luna was always a lonely mare as you now know for who else would build this 'love chamber' as your brash tongue loves to call. She once took a stallion in the presence of the court to demonstrate her power and dare any pony to act- none did of course, but..."

"I can't imagine such a display happening today, but I can only assume it had the opposite effect?" I asked, and Nighty nodded.

"Indeed. It only perpetually slandered our name further as a lust demon who would steal ponies while they slept."

It was of course with further context that the whole reason for her love chamber as I called it came into existence as the shadows really became a home for Luna/Nightmare to escape the hated glances and sharp words of a society that didn't want her.

"You are more quiet than before Dusk, maybe we were too aggressive with the physical discipline. We did not take kindly to thy words young prince for their possible implications."

"You were doing very well for a while, Nighty, but I will apologize. I meant nothing by them, but the way you described it mirrored our modern interpretation of what is considered more of the kinky side of love making."

"Kinky? We are unfamiliar with how a communal chamber is viewed with a stiff body, or why the association has to be hidden from the general populace?"

Nightmare asked as her horn flickered to life, and mimicking the hallway forced nearly three dozen candles to spark alight for the first time in ten centuries. Hanging high above the chamber was an old chandelier made of stained glass in the shape of Luna's cutie mark with the remaining candles buried into their own dugouts, and from here they projected their dim light into the chamber. Yet none of this was enough to fully illuminate the entirety of the chamber for anything practical like reading, but it was enough for a pony to sufficiently see the ground and the few objects such as old pillows that had faded with age. All of this was enough for the alicorn to see without causing any discomfort.

I watched as she began exploring the chamber, and noted how her ears were erected, as her movement was stiff- agitation carried her limbs as she prodded a pillow, huffing as it disintegrated.

"There is another meaning associated with the word when you add the letter Y to it. It shifts the meaning from a conversation of stiff joints to seeking pleasure in unusual ways." She stopped to turn her head.

"Unusual how?"

Before my relationship with Nightmare Moon, the idea of casually talking about private affairs was enough to make me clam up, or withdraw much like Fluttershy did when I first met her. Presently, I found it less intimidating as my experience in the matter has grown, and to my surprise have had to teach Nighty some things as they simply didn't practice the acts during her time.

"A good comparison would be when you or myself would derive pleasure from licking each other..."

"NOT SO LOUD!" Honest to Celestia, I blinked in surprise as her agitation morphed into embarrassment as her ears pinned themselves to her neck, and feathers seemed more fluffed.

"That is one example." I continued with my explanation. " Oral pleasure is viewed with more acceptance in pony culture, but is still regarded as inappropriate to discuss."

"We would certainly agree! For the more you teach us of current Equestria, the more we conclude sister is a deviant." Nighty may not have caught it, but I've been noticing her casual use of the words sister/s over the course of the past few weeks.

"But that hasn't stopped us from enjoying it? You even admitted to performing Oral before your confrontation with Celestia." I didn't wait for an answer as her body posture told me everything I needed to know. "That is considered more modest if you will believe it, as the act itself can be viewed as an extension of traditional mating. We haven't even broached the more risque acts."

"Dusk Shine..." She huffed my name out as she collected her composure. "...you surprise me with each meeting. Perhaps I have grown older to not have seen it from our first meeting those years ago when you were a little colt trying to act brave."

"Act brave? I was brave." My statement earned a deep laughter from the mare as she stalked toward me, and I didn't need a written letter to recognize her intentions, for it was the precursor to the more pleasurable entanglements. Not saying I don't enjoy our sparring matches, but these sessions often meant less soreness...

Well that depended on a great many factors.

"Foolish I would say, but you have grown enough to catch our thoughts." Her eyes were reflecting the dimming candle light in an unnatural, clinging way to create this mass of shadows being led by the two snake-like eyes. "If you were born a few centuries earlier, we might have claimed you for ourselves, and not that game Celestia loved playing with the common folk. Did you know dear Dusk she would lead a pony on just to play coy with them? Oh yes, she did. Celestia doesn't know it, but Luna, and by extent We know of her favorite interest..."

By now she had covered half of the chamber, and this only further amplified the size difference between us. I took a step back unintentionally, and this only encouraged the lustful mare stomping toward me.

"What kind of interests?" I asked hoping to distract her as I abandoned my bravado to retreat toward the door. I could see the candle light glistening off her fangs as her smile widened with glee.

"Oh Dusk! If only you knew what we did, but fret not for you will! We are brash to call Luna a whorse as We meant the insult to prick her only, but Celestia..." I didn't even realize Nighty had closed the distance to be breathing down on me."... she would disguise herself and slip out under the cover of night. It is only in our realm did the piteous alicorn devour stallions and mares alike with a hunger enough to make us blush. It is our home. Our comfort, but Celestia loses herself in it!"

It was at that moment Nightmare struck and barely offered any resistance as she dragged me toward her grinning eyes, and before I knew it, she had picked me up and slammed me on my back. Thankfully my wings were already flared out, so I skirted any real damage save for shock of impact and wind being expelled from my lungs. I only had a single second to process this before I felt her weight upon me, where she practically bit my lips trying to steal a kiss before using her brute strength to push me along the floor to better position herself for what was about to come next...

I laid still as Nighty's muzzle pressed firmly against my sheath with enough force to elicit a sharp inhale of breath from me. She loved doing that, pressing her chilling nostrils just under the sheath where it connected to the scrotum, and deliberately inhaling loudly so I may hear as well as feel the intake of air.

This fascination had always confused me, and every attempt to learn of its place in our lovemaking was met with stern refusal to talk, or in rare circumstances, she might bare her fangs long enough until I dropped the question. All of that wonder and mystery was answered when she revealed more of her past, and this formerly hidden chamber tonight, yet all it did was further open our relationship to the whims of more questions and answers.

Until a designated time can be agreed upon, I will not bother her needless talk. This was Nighty's ritual, and having spent enough time reading and experiencing it in practice, I've learned it was best to allow her the time uninterrupted.

The cooling floor and Nighty's warm breath melding together in a strange pleasure that covered me like a warm blanket on a cold night. It never took long for my own breathing to slow down, and I used this natural response to focus on the attention I was receiving. Because she was beginning to make her move, and I was eagerly awaiting for it.

Nighty's muzzle moved down the raphe of my scrotum in a way it forced each of my testes to their own pouch, giving herself free access to each one. She always focused on the left teste first, where she would leave a single kiss before rediscovering my right testis, and place another kiss as well; This process usually repeated on average one minute total, with the longest having lasted (by my calculations) eight minutes before...

I almost kicked her on reflex! I caught myself and my right leg just as the dominating alicorn I called my lover opened her mouth to allow the tips of her fangs to caress the skin of my scrotum. Use of the fangs were very rare amongst our numerous sessions, and even then the act was nothing more than a tool to further enhance the sensations of passion between us.

This time was different, and I could tell by the prolonged nature of her movements this was meant to be more.

Nighty had crawled forward so her forelegs were resting on top of my rear legs to pin them flat against the stone floor. This new position gave her greater access to my body which she took full advantage of by laying down her head on my exposed stomach. I lifted my head so I may look upon my lover, who made no effort to hide that predatory look from her eyes, or lips as they curled up, exposing the glistening points of those unnatural fangs Nighty loved fawning over.

'Her best quality next to her eyes.' I thought just as my lover shifted back until her head was laying directly over my sheath and partly exposed penis.

I always tried watching Nighty when she got like this as I enjoyed the feeling, and watching how she seemed not to suck on my penis, but tended to it with a care seldom seen from the misunderstood alicorn. I never understood how the Elements of Harmony did it, but when they blessed Nightmare Moon with a body of her own had to use Luna’s memories as template for the barest of basic instincts; learning more of her (Luna’s past) only a modest couple hours ago, had turned this act of pleasuring into another effect derived from loneliness.

To simply take pleasure from performing oral sex is more to sate her desire for affection, touch, and desire to share a moment with another pony- even if the act often was one-sided.

“Thankfully it's not…” I moaned softly as her fangs dragged along the surface of my penis, from the bottom of my raphe where it connected to my testes along the entire length of my penis until she reached the ridge of my corona glandis.

Here I fell silent once more as her fangs traced the outline of the ridge flare and over, leaving their sharp points resting on the tip of my penis. Our eyes met, and groaned as her long tongue left her smiling mouth to wrap itself around the girth of the tip, where she reversed her ascent so her fangs would drag along my penis length with her tongue following close behind.

She repeated this another three agonizing times before settling her attention to the flare of my penis where she began to suckle on with a tenderness that caused my rear legs to buck and squirm as the sensation began agitating my muscles. Here she used her fangs to keep my penis from moving, pinning it between her fangs so her tongue could snake itself along the length while gripping and twisting.

Nighty is an export of her craft, and I don’t mean it in a derogatory sense, but as a way to mark her skills are comparable to a master in their field. You will find no half hearted attempts like the mares and occasional stallions in Canterlot will flaunt during a nightly run down the street, for they perform out a necessity, or desire for a quickie.

Here, under the care of my lover will be another moment those street walkers will never understand, and it was unfortunate I was reaching my limit so suddenly. This didn’t mean we were finished. I still had to return the favor, and after a quick rest roughly 3 hours long we could resume our love making in earnest further demonstrating an alcorn’s regenerative abilities were unmatched.

One of the earliest rules we created was the usage of the unspoken word using gestures with our hooves, and wings to signal a multitude of commands to alert the other. It was this agreed upon gesture I began tapping my left foreleg on the ground in a pattern of two quick taps. Silence. Two more taps. Silence and repeat. This was meant to alert Nightmare Moon that I was reaching a critical point. Sometimes she would retract her effort to create a momentary rest period to provide me enough time to get my focus back…

“Ooooh!” I couldn’t fight back the lust in my voice as she proceeded to see how much of penis she could engulf. I had to lay my head down as my eyes couldn’t keep focus as my body diverted the energy to hearing and touch to process what Nighty was doing.

Her sharp fangs rubbed up and down the length of my penis as her tongue twisted and constricted around my girth in a way I’d never felt her do before. I lost control of my legs as the instinct to buck my hips overwhelmed my mind, and Nightmare countered this by further pressing her barrel into my groin effectively pinning me to the stone floor- she said nothing. I couldn’t even hear the wet smack of her lips, nor the slurping one makes when drinking through a straw! Even my wings were limp from her technique as I found it impossible to be startled by the unrivaled bliss she was bestowing upon me.

After becoming an alicorn, I was greatly relieved to have discovered the dread ‘wing boner’ was nothing more than a neuromuscular condition meant to lock pegasi wings during mating to prevent potential damage from excited flapping. The fact Nighty’s exceptional oral skills hadn’t even triggered this condition only proved the alicorn is in a league of her own, and somehow I was chosen to be the recipient of her gift.

I was at my limit, and did our conceived hoof signals to alert her of this boiling climax, and all I got was the fear eliciting fangs speeding up as she now began making a thick gurgling noise as a response. All of these stimuli proved too much to my overworked body, and I felt myself give in to her demands- there was no grandiose celebration as in the books. One moment I felt a tickle, and an increasing build up of pressure, and next there was a feeling of relief as the pressure was released. My only knowledge of what happened next was from knowing how I reached that feeling in the first place, and the sensual way Nighty continually exaggerated the gurgling as a presumed mixture of saliva and seman moved along my already softening penis.

Risking more temporary blindness from an ocular migraine due to overstimulation, I raised my head to see Nighty panting over my softened penis laying in a pool of seman and saliva with her adding to the growing pool. Somehow she looked more beautiful and that wasn’t from the hormones still coursing through my bloodstream either let me be clear, but this increased attraction stemmed from how soft her features appeared in the dim candle light, as if under their cover she could be more of the mare I thought she wanted to be.

“Nighty…” I panted out as a statement and not the question I had wanted, but she still responded.

“I..let us finish…”

What came next surprised me for a second as she began adjusting her resting mass to crawl up my body while making sure she didn’t put too much pressure on me as she did so. She quickly did so not even showing regard to the pull of bodily fluids as she smeared them along my lower stomach all the way up my barrel; by this point her head was hovering only a hoof away, and the scent of sex and her consumed my smell in a way that left me further entrenched into the moment.

She leaned in and bit the top of my muzzle, not enough to draw any blood, but enough to leave an indent in the skin before morphing the bite into a drunken kiss as she tried rubbing what was left catch over my muzzle. I didn’t fight it, but instead tried making it into a game of sorts to see if I could catch her writhing tongue, and twice I nearly did, but she would grind her soft underbelly against my penis and content testes to distract me.

“They will know…” She muttered before freezing opened mouth against my muzzle so I could once more smell myself in her.”...we are mated. Not them Dusk. WE are mated.”

“They will in time, Nighty.” I seized this chance to return the favor and licked the side of her cheek, causing her to withdraw. “I promise you that much, and then after that maybe we could do something together?”

She was still, and silent as she continued looking down at me, save for the closing of her jaw. I continued.

“We will show Equestria you are a mare of your own, and I’m proud to be with you. We could see the world, just the two of us. What do you say?”

Her silence worried me for good reason as Nighty had always been a fickle mare when it came to certain triggers like Luna, Celestia, dirt, and losing to name the biggest offenders, but this was me opening myself to her critical judgment of my proposal. My heart was beating faster once again as she carefully arced her neck down so our noses could touch, and eyes could stare directly into the other’s soul, and my heart nearly beat itself to death at what I gleaned from those soft teal eyes.

“You are a very big dreamer lover colt, and lucky for you…” She withdrew enough so our noses no longer touched, yet enough for the dim light of the candles to illuminate her eyes till they shone like stars in the night sky. “... we like dreams.”
