Author's Note

I separated this Lemon into two chapters for ease of reading. A new chapter, for a new scenario. Enjoy~

A Different Kind of Demonstration

Silver Wing awoke abruptly to a knock on his door. He sat up quickly and looked around his room in surprise. He was in his room in the Canterlot Royal Palace, and he was alone.

"W-whaa...?" he mumbled as he slowly came to his senses. Images of the night before flashed in his mind and his eyes went wide as he recalled a very intimate encounter with Princess Luna.

The knock came again, louder this time and Silver shot a concerned glance to his door. "That couldn't have been real, could it?!" he stammered, "If that's her at the door... Then that means she's here to take me to Celestia so that I can-"

"Sir Silver Wing, are you in your room?" A stern, male voice called from beyond his door.

Silver let out an audible sigh of relief and shook his head. "Yeah," he called back, "I'm here, just a second!"

'Of course it wasn't real,' he thought as he moved to climb off his bed, 'Like something like that could ever-' As Silver's foot came to rest on the floor, it abruptly shot out from under him as it slipped on something.

He dropped to the ground hard and glanced angrily at his hoof. He paused as he saw a slightly tacky white substance on it and glanced in horror to where he had stepped. A fairly large puddle of a semi clear, white liquid rested on his floor just off the edge of his bed. As he stared at the liquid, he noticed a stain running up the bed sheets above to the top and gasped.

"Oh my god, I fucked a Princess!?" he nearly screamed.

"S-Sir?" he heard call back to him from beyond the door, "A-are you alright?"

"Crap!" Silver cursed as he recalled the guard, "Y-yeah, sorry. I'm com- er, I'll be right there!"

Silver quickly wiped his hoof off on his bed sheets and dashed to the door. He opened it part way and tried to look as nonchalant as he could.

"Yes?" he said with forced calm, "What can I do for you?"

The guard eyed him oddly for a moment, then cleared his throat before he spoke. "Your presence is requested in the Royal Dinning Hall in one hour’s time for dinner. Can you attend?"

"I'd love to." Silver said, a heavily forced smile masking the concern he felt.

"Very well then," the guard said, "Will you require an escort?"

"No thank you, I know the way." Silver said. He walked out of his room and closed the door behind him.

The guard moved aside and bowed politely. "Very well then," he said, "Please do not be late." At that, he turned and headed down the hall in the opposite direction.

Silver's heart was racing. If the events of last night really had happened, he had one heck of a task ahead of him tonight. He took a deep breath to calm himself and turned his mind to figuring out a game plan.

He looked himself over and frowned as he noticed a tightness in the fur between his back legs. 'First things first,' he thought, 'I need to have a quick bath. One problem with fur like this, the after effects of making love seem to linger.'

Silver returned to his room and ran a hot bath. He cleaned himself thoroughly, then headed for the dining hall at a slow trot, giving himself plenty of time to think.

He was still nervous, but the bath had helped him to relax. He had never had a problem pleasing a woman, but being thrust into a scenario like this, where he was basically being forced to sleep with one sister by the other. Both of which who happen to be Princesses, and the reigning rulers of a country, was enough to give anyone more than a little tension.

Silver arrived at the dining hall at the turn of the hour. He was ushered in by the guards, then left to await the Princesses. They entered shortly after and greeted him in turn as they seated themselves across from him.

"Greetings Silver Wing," Celestia said with a polite bow of her head, "I was not aware that you would be dinning with us tonight."

"I invited him Sister," Luna stated, "The three of us have much to discuss."

Silver's heart dropped. 'She hasn't told her yet?!' he thought in shock, 'She can't seriously be planning to bring this up over dinner!?'

"Is that so?" Celestia asked. She glanced at Luna quizzically then smiled. "Very well then. First let us enjoy our meals, then we shall discuss whatever it is you two seem to be plotting."

Luna smiled coyly for a moment then shrugged. "As you wish."

The dinner that followed was one of the longest Silver had ever experienced in his life. He wasn't sure when Luna would tell her sister of her plan, but the wait was beginning to make him incredibly anxious.

After everyone's plates had been cleared and the servers had departed, Luna turned her attention to Celestia and smiled. "So, dear Sister," she started casually, "Tell me. When was the last time you had something other than the magic of your own horn force itself inside you and make you cry out in pleasure?"

Silver's jaw literally fell open at the directness of Luna's question. She had asked it so casually, and with no warning or build up at all.

Celestia held a similar look of shock on her face. Her eyes were wide with confusion and she had an overall air of bewilderment about her the likes of which Silver had never seen. "E-Excuse me?" she stammered.

"You heard me, Sister," Luna stated, "When was the last time you allowed yourself to be pleasured by another?"

"I do not know what has gotten into you, but this is not the place for a discussion such as this!" Celestia barked, her anger clear in her tone.

"This is the perfect time," Luna said, "You are in dire need of some experienced attention. And I have just the Pegasus to assist you." She smiled over at Silver and waited.

Celestia glanced over at him as well and stared at him with a rather menacing glare. "Is this truly your reason for joining us tonight, Silver Wing?" she barked, "To attempt to solicit sex from me!?"

Silver shook his head frantically, but before he could get a word out, he noticed Luna's horn begin to glow.

An instant later, a bright beam of purple light fired from its tip and struck Celestia in the side.

Celestia went rigid and gasped out in startled pleasure. She collapsed to the floor a moment later and spasmed uncontrollably as sparks of what looked to be purple lightning danced across her form.

"Luna!" Silver barked as he leaped to his feet, "What are you doing!?"

"Calm yourself, Silver Wing," Luna said, waving him off irritably, "My Sister is unharmed."

Silver flew over the table and landed between Celestia and Luna protectively. He wasn't sure what was going on, but he wanted answers before he would allow anything else to happen.

Luna smiled at him and let out an amused sigh. "All I did was share the wonderful experience you gave me last night," she said softly, "Only, unlike myself who had the better part of a few hours to savor the sensations granted, my Sister was subject to them all in an instant. As such, she will need some time to recover."

"Wait, you did what?" Silver asked. He was astonished. He had no idea magic could transfer feelings like that to another. He found himself wondering what that would feel like. To have the culmination of an entire sexual encounter condensed into a single second. He glanced at Celestia and noticed a heavy blush was now clear on her face. Her back leg was twitching and though her eyes were open, her expression was vacant and hazy.

"How long is she going to be like that?" Silver asked, still a little concerned for her.

"Long enough for us to get her to her room and prepare." Luna said, an evil grin creeping onto her face. She walked over to Celestia and motioned for Silver to come closer.

He did so, and as soon as he was standing beside them Luna's horn began to glow brightly. Its light grew in intensity for a few moments, then a blinding flash engulfed them all.

Silver blinked his eyes rapidly, and when his vision finally returned, he found himself standing inside a large circular bedroom.

"Where are we?" he asked.

"Welcome to my sister's bedroom," she said, clearly pleased with herself, "Now, let us prepare. I have much to tell you about my Sister and we have little time."

Silver listened intently as Luna gave him details on her Sister's sexual preferences, and by the time Celestia regained her senses, everything was ready.

Celestia awoke in her bed. Her curtains were drawn, but a soft yellow light filled the room. It took her a moment to notice them, but countless candles were setup all around her and the smell of incense hung heavy and sweet in the air.

"Welcome back to your senses, my Sister," Luna called to her from nearby, "I trust you are ready to enjoy what I shared for yourself now?"

Celestia didn't speak at first. Her mind was still racing with the images Luna had shared, and her body still tingled unbearably at the lingering sensations. "Where..." she whispered huskily, "Where is he...?"

Luna grinned and nodded nearby to where Silver Wing was waiting.

Celestia followed her gesture and spotted Silver. With an abrupt flash of light, she teleported directly before him and forcefully pinned him to the wall in one sudden motion. "Do not disappoint me, Silver Wing," she growled almost angrily, "I have not felt this way in centuries. If you do not quell my fire..."

Silver was caught off guard for a moment by Celestia's sudden appearance before him, but he knew how to handle things from here. By the way she was acting, it was clear to him that Celestia hadn't taken care of herself in a very long time, with another or otherwise. She must have locked all such desires away deep inside herself, and now that the floodgates were opened by her Sister, she was practically salivating at the thought of having him inside her.

"I have faith in his capabilities my Sister," Luna said as she moved to a nearby cushion to watch, "If I did not, I would never have entrusted your needs to him."

Silver wasn't the biggest fan of having an audience, but he did his best to ignore Luna's watchful gaze and got to work.

Celestia's pin on him was good, but Silver's fighting experience had taught him much about grappling. Twisting his shoulders and using his hips, Silver reversed the pin.

Celestia gasped in surprise, then moaned as she was thrown to the ground. She slithered her spine provocatively and grinned up Silver wildly.

Luna had given Silver a great many details about Celestia's sexual preferences while they had been preparing. One such detail, was just how much a forceful lover turned her on. Gentle, sweet love was always nice, but for some, passion was best shared rough and fast.

Celestia was larger than Luna was, but it was mostly in the legs. Her actual body was only slightly bigger, so Silver had little issue reaching all the right places. He pinned her front legs to the ground over her head and without warning, plunged his fully erect member straight into her neglected womanhood.

Celestia arched her back hard at the abrupt penetration and moaned deeply at the fullness she felt stretching her insides. "Yes~" she cooed lustfully, "It's been to long~"

"What was that?" Silver teased, thrusting into again, "I'm too long for you?" He pressed further into her and she moaned hard.

In his new equine form, Silver's penis was quite a bit larger than it had been as a human, both in length and girth. His new size was too much for any female to handle, and he knew this, but such sizes were normal with equines. Luna could barely take half his full length, and even Celestia, with her larger body, still left much of him outside her straining lower lips.

"Maybe I should put it in somewhere where you can take it all then, hmm?" he whispered as he watched her eyes closely.

Celestia's eyes widened as she caught his meaning and she shook her head quickly. "Y-you can't mean-" she started, but Silver was already on the move. He withdrew in one fast motion and grasped at her hips firmly.

"I mean exactly that," Silver stated, "So you'd best prepare yourself Princess." He tugged hard and flipped her over onto her stomach.

Celestia protested weakly and shook her head from side to side as she was repositioned, but despite her verbal protests, she made little if any physical attempt to resist.

This was another detail Luna had shared with Silver. Celestia, despite her unrivaled power in the eyes of the rest of the world, loved to play the victim, and Silver would happily oblige.

He propped her hind end up onto her knees and pressed his thick cockhead against her tight asshole. With how wet Celestia had been, nearly his entire length was well lubricated with her juices, so Silver had little doubt he’d have any issue working himself into her.

He smirked as he caught the faintest wiggle of anticipation in her raised ass and shook his head as she continued her protests. She clearly wanted this, and despite the mock fear in her eyes, she made no effort to move even an inch from where he had positioned her.

"Oh hush, you know you want this, so be a good girl and take it already." Silver stated sternly. He slapped her on her flank, square against the cutie mark and pressed into her harder.

Celestia winced at the slap, then gasped abruptly as she felt Silver's cockhead force its way inside her ass with an audible pop.

Silver shuddered a moment at the intense tightness he felt constricting his tip and waited for Celestia to adjust.

He started to reach a hoof down between them, then frowned as he remembered his lack of real hands. He glanced over to Luna and tapped his forehead a moment, before pointing at her.
'Luna,' he called with his mind, 'Luna can you hear my thoughts right now?' He knew Luna had the ability to read minds. She had done it to him before, but he couldn’t be sure she was listening now or not. He could only hope his hoof gesture made sense to her.

'Luna?' he thought again, 'Can you hear me?'

After a moment, Luna regarded him curiously and nodded.

'Good,' Silver thought, 'You did something last night in my dreams that gave me my fingers back, can you do that again now?'

Luna raised an eyebrow for a moment, then grinned cheshirely. Her horn glowed a moment, then returned to normal.

Silver didn't feel any different, but glancing back to his hooves revealed them to be glowing with a faint purple light. His feet still looked like hooves, but as he recalled what it felt like to wiggle his fingers, faint tendrils rose out of his hoof and wiggled as a finger would have.

'Perfect!' Silver thought, 'Thank you very much Luna.'

She smiled wider and laid her head down as she waited to see what he would do to her sister next.

Silver slid a glowing fore hoof between himself and Celestia and reached under her. Deftly, he slipped two of his magical fingers inside her burning slit and wiggled them about furiously.

Celestia gasped sharply and shot a confused look over her shoulder to see what had just worked its way into her.

As she looked back, Silver grinned into her eyes and thrust a good third of his rock hard cock deep into her stretched ass in one smooth motion.

Another gasp escaped her and she shook her head quickly. "N-not so fast Silver Wing, please!" she pleaded.

"What was that?" Silver asked, thrusting another few inches in, "I'm afraid I missed that."

"Hnngh!" Celestia tensed as her insides were forced to accommodate even more of Silver's organ and panted as she found herself momentarily out of breath. "G-go slower," she said shakily, "Ple-"

Midway through her plea, Silver curled his magical finger down and ran them hard over the sensitive ribs on the roof of her inner walls.

Celestia dropped her head to the floor and cried out in pleasure. While she had felt this sensation before when Luna had shared her experiences at dinner, Celestia had received it all in an instant. Feeling such a thing first hand however, and over a much longer duration, made her mind go blank.

Silver chuckled and ran his fingers over her g-spot more vigorously as he slid himself even further into her straining ass with another small thrust.

Eventually, Silver withdrew his magical fingers from her and pressed his hooves against her ass cheeks. The tendrils of magic spread out from them and grasped at her flesh firmly in preparation.

He had only a few more inches of his raging erection to go and he savored the view he had for a moment. It would have made a nice picture. Celestia, on her chest before him, ass raised high as she looked back at him with a furious blush on her face.

Celestia's eyes fluttered a moment as she gradually regained some of her composure. Silver's fingers had done wonders for her, but she was still in dire need of something more. She felt Silver's fingers squeeze her ass cheeks and took a deep breath as she realized he was about to go for the final push.

Abruptly, Silver thrust hard and embedded himself to the hilt in her wondrous ass.

Celestia bit her bottom lip and tensed as a pained moan escaped her lips.

Silver leaned over her and laid against her back, giving her time to grow used to him being so deep inside her.

Celestia shuddered as she felt him shift inside her and panted hard as Silver's weight pressed down onto her.

"Shh now," he whispered into her ear, "You'll be begging for more in no time, I guarantee it." He kissed the side of her neck softly and slowly began to withdraw himself.

Celestia cringed as she felt her insides shift, then gasped out as she was abruptly thrust into again.

Silver went slow at first, then gradually fell in to a steady rhythm of pumping in and out of his gasping partner.

Celestia's discomfort swiftly faded, and before long, she was thrusting her ass up to meet Silver's ever harder down strokes.

"Yes, yes, yes~!" she cried out as she felt herself reaching her first orgasms in countless years, "Don’t stop now, just like that, yes!"

Silver was pumping into her ass like a machine. He'd pull out nearly two thirds of his full length before slamming it straight back in right to the hilt.

Celestia's ass slapped hard against him every time, and she only seemed to grow more frantic and heated as time went by.

Silver caught a glow creep up along Celestia's horn in much the same way Luna's had when she neared her orgasm in his bed and he sped up his pace even more.

Sparks abruptly flew from the tip of Celestia's horn and she cried out in ecstasy. She came hard, and her knees gave out instantly.

Silver anticipating that however, and though he nearly came himself as her ass constricted even harder around him, he dropped with her and continued his rapid pace without pause.

"S-stop now Silver Wing!" Celestia gasped out as her orgasms intensity failed to wane, "P-please, just for a moment!"

"No can do Princess," Silver said, "I like the sounds your making right now, so I think I'm gonna listen to them for just a little while longer before I let you stop."

"Y-you monster!" Celestia protested.

"Hey, you wanted this, remember?" Silver stated, "But if you want me to be a monster, I suppose I could just unload all over you right now and see what you think of that?"

"Y-you wouldn't dare!” She stammered, "You can't! I'm your Princess!"

"And I'm your monster apparently," Silver grinned, "So you tell me, what wouldn't I do, hmm?" He hefted her ass back up and propped her on her now trembling knees once more. "Well?" he pressed, "Do you think I wouldn't paint you even whiter with my seed? Or perhaps we should just move this over to your balcony so that all of Canterlot can see the state you're in?"

Celestia tensed and swallowed hard at Silver's words. She wasn't sure if he was playing anymore or not, and though she had been enjoying his forcefulness up until now, she was beginning to grow concerned. She tried to stand, but Silver's pace had not changed. Nor had the intensity of her orgasm. His unrelenting pounding of her ass was still holding her over the edge and she hadn't the strength to stand, let alone resist him.

"No, I suppose not," Silver said finally, "Our current audience is enough for now I think. And speaking of our audience, let's give her a better show than we have been, shall we?"

"W-what!?" Celestia gasped as she recalled that Luna had never left her room. She glanced past Silver and blushed furiously in embarrassment as she found her sister to be laying nearby, smiling wildly at them as she watched.

Silver's hip muscles were beginning to lose their stamina. For the last several minutes, he had been thrusting as hard and as fast as he could. He wouldn't be able to keep this pace for much longer, so he needed a change of pace anyways.

Wrapping his arms around Celestia's softly furred waist, Silver hefted her up against him and spun them both so that they were now facing Luna's nearly unblinking gaze. As he moved them, Silver let gravity pull them backwards and dropped onto his butt hard. Celestia, being so firmly held in his grasp, followed after him and slammed down into his lap. His already deeply embedded cock was forced inside her deeper than ever and she gasped out in pained pleasure at the sudden shift.

Glancing down, Celestia saw a visible bulge trailing faintly along her abdomen and watched in pleasured awe as it shifted higher and lower with each of Silver's continued thrusts.

"Oh my," Luna cooed as she took in the new view of her sister, "You do seem to be enjoying yourself, now don’t you dear Sister?"

Celestia glanced up at her and tried to close her legs to hide her dripping snatch, but Silver wouldn't let her. He wrapped his back legs over hers and pulled her legs open wide for Luna to see.

"N-no!" Celestia squeaked, "Don't!"

Silver ignored her and reached around her waist, slipping a hoof down between her spread legs. "Time to cum ever harder Princess." He whispered up to her.

She glanced down at his hoof and gasped as she watched a shadowed hand form and abruptly assault her nethers.

Silver's fingers slipped into her eager passage and wiggled about wildly for a moment, before sliding up and rapidly running back and forth over her sensitive clit like a cloth over a washboard.

Celestia threw her head back and cried out at the intense addition to the already overwhelming pleasure she was being subject to. She came even harder, so hard she forgot how to even breathe. Her body locked up and trembled uncontrollably as her senses were overloaded, and she eventually lost consciousness altogether.

Silver felt her fall limp against him and stopped his ministrations. "Hmm," he said, feeling a little sheepish, "I know you said to go hard and not to let up on her Luna, but I think I may have been a little too hard. She's fainted..."

"You did exactly what you were supposed to do, Silver Wing," Luna said happily, "More than I had even hoped in fact! And you put on quite the show as well. My dear Sister will be unable to walk in a straight line for some time I would imagine."

Silver chuckled a little and let out a heavy sigh. He still hadn't gotten off, and his balls were beginning to feel the strain. He had held off on cumming himself as he wanted Celestia to reach her peak first, which she had, but he didn’t feel right finishing with her unconscious.

With slight regret, Silver began to withdraw himself from Celestia's heavenly ass.

"What are you doing?" Luna asked, seeing him start to pull out, "Are you not going to finish?"

"I would, but she's out cold," he said, "It wouldn't be right."

"She will not be pleased to find out that you did not reach your climax as well, Silver Wing," Luna cautioned, "You had best relieve yourself within her before you withdraw, lest you wish to offend her."

Silver half frowned at her, not entirely certain if she was being serious or not. After a moment of debate, he thrust back into Celestia and focused on himself for a change. It did not take him long to feel the pressure swelling up inside, and with a low moan, he came hard inside his sleeping Princess. His cock swelled and spasmed inside Celestia's ass and fired its sticky gift deep inside her.

Luna watched as his shaft pulsed and grinned to herself as she imagined how her sister felt at that point.

With a heavy sigh of release, Silver laid back to catch his breath. It had been months since he'd last done something like this, and having had sex two nights in a row now gave him such a feeling of elation and peace that he couldn't help but smile.

"You look quite pleased with yourself." Luna commented, "Was my Sister's ass such that even you have been made speechless by its caress?"

Her voice sounded closer and as Silver glanced towards her, he found her to be walking towards him. "You have no idea," Silver admitted, "I could do this every day for a hundred years and still look forward to the next time."

Luna raised an eyebrow as she regarded him and smirked. "Oh?" she said coyly, "And what makes you think there will be a next time?"

"Not saying there will be," Silver said, "I just mean, some things never get old. And this? This is one of those things I will never get tired of."

Celestia stirred and moaned as she found Silver to still be fully imbedded inside her. She glanced over at him weakly and smiled. "Is that a promise?" she asked heatedly, "Would you truly be willing to sate us like this every night for one hundred years?"

"Us?" Silver repeated. He glanced to Luna and watched as she laid down beside them and snuggled closer.

"Yes, us," Luna stated, "My Sister and I. Unless you do not think you would be up to the task?"

"I would give it my best shot," Silver said honestly, "Though I don't think my body would be able to keep up for quite that long."

"And if it could?" Celestia asked seriously.

"Yes," Luna chimed in, "If your body could keep up, would you stay with us, like this, for one hundred years? Or even longer?"

Silver chuckled a little uneasily and shrugged. "Who wouldn't?" he said simply.

"Most excellent." Celestia said happily.

"Most excellent indeed." Luna agreed.

They shared an odd smile with each other and Silver began to think he was missing something again.

"I'm a little lost," Silver started, "What's going-" As he spoke, Celestia rolled her hips and moaned as she felt Silver's still erect cock shifting inside her as she moved.

Silver moaned as well and looked between the two Princesses in growing confusion as their horns began to glow brightly in unison.

A strange tingling sensation began to course through Silver's entire body as the light struck him. He felt himself lose all sense of time and feeling as his mind was rapidly overcome with intense and unknown sensations. "W-what's going on?" He asked as he found his vision fading, "What are you two doing to me!?"

He heard no answer, but with a sudden and almost explosive jolt of pure energy, Silver Wing was thrust back into the world.

He was still on his back. But a strange shifting sensation was growing around his cock. Glancing down, Silver gasped as he found both Celestia and Luna to be laying on either side of him. They were both licking his fully erect member eagerly and he nearly came as he realized what it was that he was seeing.

"Mmm," Celestia cooed as she kissed the side of his shaft tenderly, "Welcome back Silver Wing, you have been asleep for nearly four hours."

"Four hours!?" Silver exclaimed in surprise, "Why!? What happened?"

Luna ran her tongue up the full length of his shaft, then rested her cheek against its tip as she smiled at him lovingly. "We have given you a great gift, Silver Wing," she stated softly, "Now you can keep sharing your passion for one hundred, or even one thousand years if you so choose."

"What do you mean?" Silver asked. He was thoroughly confused and he had no idea what they meant.

"You are now one of us," Celestia cooed, "You are now Silver Wing, the Alicorn of Passion."

"W-what!?" Silver gasped. Immediately, he shot a hoof up to his head and found a long horn protruding from his forehead.

"Once you have mastered your new form and the powers it possesses, you will be able to spread your passion throughout our bodies and minds in ways which we have never dreamed!" Luna said eagerly.

"Yes," Celestia cooed, "Please, share you passion with us every night henceforth, Silver Wing. Starting right now!"

Silver tensed as he felt the tip of his shaft engulfed in a heated mouth and he moaned as he thought about his life’s latest turn of events.

'I have no idea how I wind up in these scenarios,' he thought, 'But I can definitely deal with this. In fact, I don't even think I want to go home anymore. I have plenty of friends, and apparently more than enough lovers here to keep me quite content for the rest of my life!'

And so it was, that Silver Wing, a human trapped in Equestria, became the Alicorn of Passion. He used his new found stamina and powers to keep the Princesses Celestia and Luna thoroughly satisfied for a great many years to come.

At the end of each day, with the setting of the sun, he would bed the Goddess of Light and send her off to her dreams with sweet whispers of pleasures to come. And in turn, with the setting of the Moon, he would share in the Goddess of Darkness's dreams and bring the joy of pleasure to every fiber of her being until the sun set once more, and the cycle began again.
