Sombra was wearing a nice, formal outfit. He wore a top hat on top of his head, with a monacle over his right eye. He wore a black and white tuxedo with a ruby red bowtie firmly attached to his chest. His pants were black khakis that went over the side of his pure leather loafers. Princess Luna glanced down and saw that she was in a silky navy blue dress, complete with white laces for the shirt underneath.

“This seems a bit much, don’t you agree?” asked Luna.

“Well, I figured I would swoon you and be romantic,” Sombra replied, his horn glowing black. “But, if you’d rather take a different approach…” he chuckled. With a quick spell, he removed all of the clothing from both parties.

“Luna, I want you to enjoy every single moment tonight. I know I will. After all, what you feel, I feel 10 times more,” Sombra said, his face beaming with lust.

Luna knew just who was taking the appearance of Sombra as she was grabbed by his magic. Using the levitation spell, he lifted Luna up in the air and gently laid her on her back. The Princess’s midnight blue eyes shone brightly beneath the moon’s light.

“I am not used to being handled so suddenly,” she blushed, her eyes taking a quick gander at Sombra’s lower head. She started to chuckle at the sight, and his smile was quickly wiped away.

“It’s like a spaghetti noodle!” she laughed. “It’s dangling there like it needs to be boiled in water! Bw-ahahaha!”

Sombra stood there, silent, his mouth parted a little bit. “Isn’t she aroused? Why is she making fun of me right now? I’m so confused...” he thought.

“I’m sorry, it’s just that it reminds me of one of my favorite dishes. It looked so adorable as it swayed back and forth….just like a noodle, pshhhh!” she snorted.

He was immediately flustered. While she chuckled to herself, he hatched an idea. A light bulb appeared inside of his head, letting him know that the plan was flawless. “Dear Luna, what say you to a challenge?”

“A challenge?” she repeated.

“Yes, think of it like a game.”

A small crack of joy appeared on Luna’s face. She kept this sign of confidence hidden from Sombra’s eyes. She knew that she had never been bested in all of her life at a game. After all, she had only ever lost to one pony, and she wasn’t here right now.

“Ok, Sombra, what were you thinking?” she asked.

“How about this. If you win, you get to do decide what we do the next time I meet you on a full moon. But if I win, I get to decide what we do on the next full moon. No exceptions, no complaints. The other party must whole heartedly agree to do whatever the other wants. There is no compromise. The only way to win is to not cum first,” the dark, sly unicorn proposed.

“Well, that is a big risk. I don’t know if I can even, DONE!” she shouted enthusiastically.

Sombra was shocked that she agreed to this so easily.

“My, my, my, it seems you’re a bit taken aback. I must admit that you made a mistake, dear Nightmare Moon, er, I mean, Sombra. It does not matter what form you take, what thing you do to me, I will win. For you see, you have stepped into my domain. The realm of dreams is a thing we share together. However, when it comes to a challenge, as a gamer, it is my duty to crush my opponent, no matter the difficulty,” Luna pronounced, passion and intensity filling her eyes.

“What have I done?” Sombra thought, tilting his head straight up. He closed his eyes, immediately regretting the challenge. Suddenly, he felt a warm sensation on his crotch. He quickly glanced down and saw Luna’s head covering his nether region.

While Sombra was occupied staring at the ceiling, Luna took the advantage and flew towards his flaccid member. She opened her jaw and planted a firm grip on his cock with her mouth. When he cast his gaze downward, she looked up at him and grinned devilishly, wet noises escaping her mouth. She cradled his tender balls, and licked around the tip of his dick.

Sombra grunted as Luna licked it like a lollipop, moving her tongue oh so carefully up and down the shaft, making sure to cover every inch with her hot saliva. While juggling his balls, she sucked deeply and feverishly before stopping at the tip. She turned her head back and forth on his rod while swirling her tongue in tiny little circles, occasionally hitting the cluster of raw nerves underneath it.

Sombra squinted as a rush of immense pleasure filled his brain. Luna chuckled with his meat pole still in her mouth. Her chuckles created tiny vibrations throughout his cock, sending wave after wave of fleeting joy into his mind. Sombra couldn’t lose like this, so he decided it was time to get serious.

Using his levitation magic again, he lifted Luna into the air upside down. He turned her around and saw the juicy, moist hole that he craved. With an amused laugh, Sombra drew the plot onto his face. Luna mumbled in ecstasy as Sombra’s muzzle moved deep within her.

He could feel the liquid in every crevice of her walls with his tongue. He lapped it up, still feeling the muffled moans from below. It seemed that Sombra had the upper hand for now as he held Luna in the air. He continued to dig his face deeper into her hole, driving Luna crazy in the process. She lustfully sucked his lower head harder. Sombra bared with this increased intensity as he shook his head between her flanks. He started to move his tongue in replica of the alphabet, making sure to stop on her clit at the end of each letter. Luna just moaned wildly as she dangled in the air, blood pooling into her brain, causing her to go insane.

She jerked and bobbed her head ferociously, lewd wet noises filling the air. She moved her hooves up to his shaft and stroked it, while focusing her tongue on the tip’s raw nerves yet again. Sombra dug deeper into her hole as he squeezed her soft, plump ass with his hooves. Luna moaned again, wiggling her flank further into his face. Sombra’s magic waned, as he couldn’t concentrate on holding her up and licking her pussy at the same time.

His legs finally gave out, and Luna fell to the floor with a deep gagging sound. Sombra’s flesh stick penetrated the back of her throat. Sombra moaned in sweet bliss while his dick pulsed and throbbed with joy. He held his head with his hooves briefly before arching himself on the marble floor. Luna pushed herself up and opened her jaw. A thick stream of saliva and precum drooled out of her mouth onto Sombra’s erect cock. Seeing this, she moved her mouth over his member and sucked up everything that remained. Removing her mouth, she swallowed as Sombra still lay there, his hooves clasped to the top of his head as he rocked from side to side, trying not to climax.

“Having this much trouble? We’ve only just begun,” pronounced Luna. She backed her flank up to Sombra’s face. He looked up and saw yet again the moist, dripping hole dangling just a few inches from his face. He could feel the intense heat radiating from it and his dick twitched in excitement.

“Your friend here wants to enter. Sorry, but access is denied. You need to collect 20 stars to enter this door,” Luna chuckled. “Don’t worry, Sombra, I’ll let you know when you reach your quota. Until then, you’re going to have to earn it. Feel blessed, as you will experience the flank of royalty. You took it by force, you naughty boy. However, this time I’ll take charge,” she said.

Luna slammed her flank on top of Sombra’s face, his hard salami rising higher towards the sky. Luna looked over her shoulder to see his expression. She didn’t know how big her ass was, but she soon realized she was only able to see him from the snout up. Both of his jaws sank into the blue and black mass of flesh while she jiggled her butt with playful jerks. Muffled words tickled her outer lips, causing her to purr with enjoyment at the vibrations from below. Making sure Sombra couldn’t escape, she grabbed his member and stroked it again. She moved her wrist in slow, elongated movements up and down his shaft. She could feel his tongue pushing deeper and harder into her melting pot, a good indicator that he was getting turned on even more. With the occasional flick of her tongue, she teased his flesh worm, making it throb and twitch in between her hooves. Luna felt soft muffled moans from her ass as she let out an aroused gasp.

“Well, that’s two stars, Sombra. 18 more and you may enter the door. That is, if you have enough star power,” Luna muttered, Sombra slaving away with his tongue.

Enjoying the taste of her excitement, Sombra began to suck on her exposed clit, its engorged area being played with. Luna inhaled sharply, her mind fluttering with sensual chemicals. She deepthroated his rod again in thanks for his hard work. In response, he grabbed her flanks and squeezed them tightly, pushing his tongue deeper into the moist and hot darkness. He sucked on her clit when he released her flanks, and grabbed them harder when he licked her walls. He repeated this process while Luna worked her tongue up and down his shaft, circling the head before venturing down his genitals. She continued to stroke him as she licked upwards again towards the tip.

Sombra’s muffled moans only provided more excitement to the Princess, her slurping becoming louder. Enjoying the sounds, Sombra swallowed Luna’s juices, tasting the sweet clear liquid that poured out from her marehood. She shuddered, her ass jiggling and moving in excitement. She still had a trick up her sleeve as she started to rotate her ass cheeks on top of his face.

She turned the left cheek in a counter-clockwise manner, and rotated the right cheek in a clockwise fashion. She continued this process for some time, savoring the feeling of the thick meaty rod throbbing in her mouth, the dick visibly extending her gums. Sombra gave her shocks of pleasure through his mouth, her pussy clenching in acknowledgment. She removed him from her mouth before catching her breath.

“Well, you’ve obtained your 20 stars. However, your princess is not in this castle,” she said mockingly. “But since you’ve been such a good little doggy, I’ll give you a treat. You may enter me, Sombra. But be warned, I’m armed and dangerous.”

Luna removed her flank from Sombra’s face and bent her front half on the ground. Her lower half was still in the air as it flirtatiously swayed from side to side. Sombra did not like being made a fool of, so he decided to take the lead this time. He calmly raised himself from the floor before sprinting towards her.

Her eyes went wide as he picked her up with his momentum and slammed her into the balcony, her chest spilling over the railing. He could see her wings completely spread out along her back and fully erect, causing him to throb with anticipation. Sombra used his hind legs to spread hers while he grabbed her forelegs with his own. He pulled them behind her back and firmly held them in place.

“You say that my princess is in another castle, hmm? Well, then, guess I’ll just have to plunder this one in the meantime!” Sombra roared.

Sombra plunged his erection into Luna’s messy, wet pussy. She let out another moan of pleasure as Sombra grunted from her tightness. He went to start moving inside of her, but quickly found out that he was having trouble. He wasn’t completely inside of her, and struggled to put his entire package into her box. Sombra could feel her walls slowly parting before his massive dick.

“Now then, time for this dungeon to be explored,” he said. Trying to pick up the motion of bucking, he found his hips wouldn’t move, thanks to the tight hole he was plunged into.

“Ahahaha, you fell for it!” laughed Luna. “I activate my trap card, Royal Pumping! With this, you’re sure to lose,” she boasted.

“Really? Again with the game terminology? Honestly, it’s growing quite old. I wish you would just stay quiet!” Sombra yelled.

“Oh, you don’t like my lingo? Guess I’ll have to punish you for that.”

In a bright flash, they disappeared from the balcony and into Luna’s private quarters. They were still connected at the hips as Luna turned on her Equestria Move.

“What are you doing?” cried Sombra. "How did we get here?"

“Well, since I know I'm dreaming, I figured I can change my surroundings. Also, I'm teaching you a lesson you’ll never forget. I’ve always wanted to game while having sex, but now that you’re stuck like this, I want to try something,” Luna explained.

She grabbed the Move remote from her desk with her levitation magic. She turned the remote on, which in turn started the system. The remote had a built-in sensor which communicated with the console. It copied the player’s exact movements and displayed these actions on the screen. Luna turned the TV on as the remote connected with the console.

“Ready for some tennis?” she said, licking her lips in anticipation.

“Wait, what?” replied Sombra.

She selected Super Smash Tennis and set the remote on the table, searching her room for some lubricant. She opened her drawer and pulled out a bottle of Dragon Lube. Chuckling to herself, she removed it from the drawer and held it in the air where he could see it.

“What are you doing?” Sombra asked as the game loaded on the screen. The remote made a pinging noise, letting them know that calibrations were complete.

She coated the remote in the lubricant while selecting her character and storage unit for the game.

“WHAT ARE YOU DOING?” Sombra yelled in terror.

Princess Luna just cast an evil smile. The curvy mare of the night cackled wickedly while raising her flank in the air. She used her magical talent and pure strength to keep it, and the unicorn still stuck inside, in the air. Sombra struggled to free himself as her strong vaginal walls clamped down harder on him, thus ensuring he wouldn’t escape.

“Stop! Stop, you crazy lunatic! You’re Princess Luna and I’m Nightmare Moon in Sombra’s body! I’m the sadist and you’re the lowly masochistic filth of Equestria! When did we change roles?!” Sombra screamed.

“We didn’t Sombra. Now role play correctly, Nightmare Moon. You’re starting to slack off. I’m beginning to become disappointed by your lack of faith in this game, and I find this...disturbing,” Luna replied, the remote inching towards Sombra’s asshole.

Sombra tried to remove himself from Luna with magic, but every time he moved, he could feel the tight walls choke his lower head with extreme force. If he tried to move with all of his might, he would’ve cum inside her and lose the bet he proposed. Instead, he closed his eyes as he felt the remote slowly being inserted into his rectum.

Sombra winced and yelled out in displeasure as half of the remote slid inside of him. Contrary to his belief, the remote was pressing against his prostate so much that it started to trigger his G-Spot. Sombra occasionally let out moans of pain and gasps of pleasure. Luna giggled with glee, content that her idea was a success.

“It works!” she shouted.

“Wait, what works?” asked Sombra, his ass dangling in the air.

“Your ass is now the controller. Where I move, you move. And since your ass is the controller, it’ll move with you. Got it, simpleton? Watch this!” Luna exclaimed in happiness.

Sombra’s face melted into despair as he felt a welling desire to cry. His jaw hung agape while Luna started to focus on the television. The CPU opponent appeared, signaling Sombra’s defeat. The game flickered, her character awaiting to serve the ball.

“Ready?” asked Luna.

“Wait, wait, no, no, NOOOOOOOOO!” Sombra shrieked. Luna cast a quick glance at her juicy flank before focusing on the television.

Sombra was lifted higher into the air and slammed down as the ball on the screen was served. The CPU returned the ball as Luna swayed her hips to the right, Sombra’s ass moving to the right due to the mare’s pure physical strength. Luna returned the ball back and scored a point against the CPU.

“Alright, 15 - Love!” she cheered.

“And how many points-”

“Shhh, I’m in the zone, Sombra. Just make sure you focus on staying hard. If you become limp and fall out of me, the punishment will be worse.” she smirked.

Sombra was scared at what this could mean, so he focused on making sure he was hard the entire time she played the game. Thankfully, this was quite easy. Every time she moved and hit the ball, the controller would vibrate inside of him. This vibration would tickle his G-Spot, causing him to thrust forward. Feeling this inside of herself, Luna occasionally moaned softly and squeezed Sombra tighter, her walls massaging his huge, rock hard cock.

This “game” of theirs continued for some time, each pony nearing their imminent finish. Luna gasped for breath, her body shaking in lust and exhaustion. Sombra was equally tired, his coat drenched in sweat. Luna needed but a single point to win the match. The problem was whether she still had the stamina to accomplish the task. Her concentration on the game had weakened her control over her vagina, her pink hole now grabbing tighter onto Sombra’s dick. Sombra had concentrated so much on staying hard that he lost focus of the matter at hand: making Luna come first.

While Luna still gasped for breath, a devious grin came across Sombra’s face, a devilish plan flashing in his eyes. Now the perfect opportunity came into view as Luna’s character was serving the ball. With his hooves, he grabbed Luna’s flank tightly and thrust with all of his might into her.

“Ngghhhaaa!” shrieked Luna as she felt his member hit her womb.

Luna’s character served the ball with such velocity that she scored an ace. Still thrusting hard, Sombra continued his unending spree of pounding her tight blue plot. Lewd squishing noises gurgled from her underside, sating her lust even more. Luna moaned in ecstasy, her face becoming redder in each passing second.

"You little cheater!" she yelled, the remote flying out of Sombra's backside.

"Nnaaahhhh!" he screamed in bliss, his prostate swelling up like a balloon.

Knowing that he was near his limit, he decided to gamble a bit. He decided to go balls deep in a last ditch effort to win this game. He wanted to make an impact inside of her and make her cum at any cost necessary.

With his mind becoming focused and full of concentration, he continued to thrust harder in her. Luna desperately tried to do a counter-attack by backing her rear end into the nearest wall. Seeing what she was doing, Sombra used his hind legs to kick himself off of the wall. With gravity on his side, Luna collapsed into the ground, her face being buried into the floor. In this position, Sombra was now in full control.

With his right hoof, he grabbed the front of Luna's hip, his dick thrusting inside of her. She tried to wiggle out of the position, but he was not having any of it. With his left hoof, he shoved her face further into the floor.

"Is this how you imagined it princess? Being violated like this, your entire fiber screaming no! but your entire body screaming yessssssss," he hissed.

Sombra's plan of being dominant was working as he could feel her walls tightening around his stallionhood. Just a little more he thought to himself. He shifted his position so now he was leaning over her back, his stomach rubbing the topside of her long, slender ridge. With her head still buried in the floor, he thrust even harder, his large black balls slapping along the underside of her pussy. Luna moaned, her eyes slowly rolling into the back of her head. Sombra continued to spank her pussy with his balls while her marehood contracted violently. He could feel the tightness on his shaft, her folds rubbing every inch of his long member. With one long final thrust, Luna screamed out her surrender, little driblets of drool running down the side of her mouth. With her vagina contracting hard, Sombra could not hold out anymore. With his own yell, he released his seed into Luna's hot underbelly. He continued to thrust while coming, wet sucking noises escaping from each thrust. He finally finished and pulled out of her, a small pool of white seed spilling out of her onto the floor. With both of them catching their breath, the room changed to a solid white background again. After regaining their composure, Sombra's appearance faded away into Nightmare Moon.

"Seems I've won the bet," she snickered.

"Y-Y-Yes," Luna huffed.

"And our agreement?" asked Nightmare Moon.

"I will oblige. You have my word."

"Good. Well, until the next full moon. I'm anxious to spank your behind again. Look forward to it," Nightmare Moon purred.

Luna awoke to her alarm clock ringing. She battered her eyes and yawned loudly, her limbs crying out in pain. She stretched, went to the restroom, freshened herself up, and returned to her room. She saw a rather large wet spot on her sheets.

“Well, at least I still managed to finish. I guess I have to wash these later then,” she said with a sigh.

Earlier that day, Celestia had heard a noise from Luna’s room while she was doing her rounds of the castle. She opened the door a bit and watched Luna thrash about in ecstasy while she slept. Celestia became aroused as she monitored her sister. She stayed outside of Luna’s room until she climaxed all over her sheets. Celestia’s face turned bright red, her marehood becoming wet. “Oh dear sister, I thought I had you this time. Well, until the next moon,” she whispered to herself. Celestia hummed quietly, her mane bouncing along with her trots as she returned to her post before Luna could see her.

Author's Note

Sorry if I tricked you but I thought of a "What if NMM won?" After thinking, I came up with this idea. I know it took awhile, but I was having writer's block, family matters stuff, exercises, me being pulled to another squadron for 2 weeks, etc etc. Primarily lazy, I decided to get back into writing. It's the least I could do for my followers and all the support that they have given me. Well, it's up to you guys if you want a sequel or not. If so, then I'll do it! In the meantime, does anyone have any future suggestions/shipping for the sisters? Yes, I said sisters.
