Luna stared at the scene, her breath coming in deep and rough, almost panting. She shouldn't have been there. She should never have come there in the first place. But that had been days, almost weeks ago, hadn't it? And yet, despite telling herself that it was wrong, she had stayed there the first time. Despite telling herself that she'd only stood there and watched because of the shock from what she'd seen, she'd come back. She could no longer pretend to be only checking if it would be the same. It had been the same every night she'd been there. And every time she had come back to it.
It had started not too long before, at the end of the previous month. One night, as she was surveying the dreams of the ponies of Equestria, she had suddenly noticed something different, something that hadn't been there before. A door that had finally opened to her after a long, long time. She didn't know what had caused it to open, but now it was.
For as long as she could remember, she had never been able to enter her sister's dreams, and see their contents. She could have forced her way in, had she tried to, but she knew better than to disturb Celestia's privacy like that. She had, after all, failed to enter them after her banishment to the moon, when Celestia had been aware of her attacks and intentionally fighting back. Trying to force things now wouldn't have led to anything good, whichever the reason was for Celestia's unconscious mind to erect a barrier around her dreams there was no telling how it would react had it been breached.
Now though, that barrier wasn't there anymore. Celestia's dreams were as open to her as those of any other pony. And naturally, when she had realised that was the case, she had been curious to see what they would be like, if a little shamefully. She had not expected it to be one of those dreams. She tried to avoid them, as it felt particularly wrong to witness something so personal. She had most definitely not been expecting the subject of the dream to be what it was.
She would never, never have thought it would repeat over and over in her sister's mind every night after that one.
The place wasn't the same. It changed every night, sometimes Celestia's bedroom, sometimes a cell in the dungeons, sometimes just a bedroom, no particular one, more rarely the throne room. The scene was always the same though.
Luna stared. She stared at herself, like she had so many nights before now, lying on he ground, panting, sweating, moaning, as her sister thrust in and out of her cunt, lying atop her and pinning her to the ground. Sometimes it was with a toy, sometimes with more natural equipments she was rather sure her sister did not possess. Sometimes Luna was tied to the ground, wings bound, muzzled, blindfolded, stripped of her magic. Sometimes she was free, and willingly submitting.
But the rest was always the same. The obsessive, slapping sound of skin against skin as Celestia plunged in and out of her body. The scent of their combined juices saturating the air. The moans echoing in her ears. The words of insult and degradation her sister kept throwing at her. And the scream. That last, final howl of pleasure as she came on her sister's shaft. Always the same, every night. And once again, the dream was over.



"Is everything alright, sister?"
Luna looked up from her plate, then hastily looked back down to hide the blush spreading across her face. She probably didn't know about the dream, and most certainly not about her presence there. Most ponies didn't know about their own dreams, really. She shouldn't, couldn't let what she'd seen ruin her relationship with her sister. "I'm alright, sister. Merely a little tired," she replied, half-stammering.
Celestia smiled. "Don't overwork yourself, Luna." She looked down to take another bite of her breakfast. "I... Well-" She giggled "-I know I shouldn't ask about this sort of thing, but were there any peculiar dreams tonight? You don't need to tell me who they belonged to, just, is there anything humourous you found?"
But how could she. How could she look at that face again, and not see the twisted mask of pleasure she wore in her dreams every night? How could she hear that voice, and not hear the echo of all the degrading insults, all the commands, all the moans and gasps of pleasure she'd heard so many times now? "Nothing of interest, sister," she replied, still looking down.
Celestia smiled once more, and cleaned her mouth with her napkin. "Well, I have my duties to attend to, so I believe it's best if I go now." She drew back her chair and got up, then walked away from the room.
Luna bit her tongue as she caught herself peeking behind her sister's tail while the alicorn left the room. She looked down at the unfinished plate of food in front of her, then lower, at the wet stain on her cushion, her hoof resting perilously close to her nethers. With a sigh, she locked the doors of the room, and let her fantasies have the best of her.



Once more, the slap of skin against skin, and the musk of arousal colouring the air. Once more, the same dream, the same scene. She didn't pretend any more.
She was there, again, and she was there because she enjoyed it. Because she wanted to see it. She could have turned away, she could have walked away, she could have decided to never look at her sister's dreams again. But she hadn't.
She took a step forward, moving closer to the centre of the vision. She wanted to see it, all of it. She wanted to see it in every detail, from every angle.  
She stopped in front of her own image, lying on the floor, panting and moaning, shaking at every thrust of her sister's hips, and she lowered her head to look at her own face, twisted by pleasure.
Her lips were parted, drool running out from them, streaming down her chin and pooling around her head, her tongue flopped out of her mouth. Her eyes were glazed over with lust, staring in opposite directions, almost rolling back into her head. Her breaths were fast and ragged, at times chocked out by particularly intense shivers of pleasure running through her. A heavy blush coloured her cheeks, dark purple on her natural blue colour.  
There was no muzzle this time, but a collar was firmly tightened around her neck, and looking upwards she could see her front hooves were bound together behind her back.  
She lifted her neck, and moved around herself, now walking up to look at Celestia's face instead.
Her sister's face, too, was flushed with arousal, her eyes just as glazed over as Luna's. Stray droplets of drool shot from her maws on occasion, whenever the princess opened her mouth to insult or command Luna. She had become oh so familiar with those words, so different from those Celestia said during the day yet so oddly fitting when spoken by her voice.
"Slut."
"You like this, don't you, you whore?"
"Take my dick, you bitch."
"You've always wanted this."
"Equestria only needs one princess. You're more fit for being a bitch anyway."
"Keep thrusting those hips, you dumb cunt."
"And you tried to take over the country? You just wanted me to punish your fat ass."
"If being abused gets you off this much you could have just asked, you know?"
"Lift your tail, slut, I want to see your pussy twitch as you cum your brains out around my cock."
Luna shuddered, and one of her hooves slowly moved down her body to caress her lower lips. There was something, something about the tone her sister used, something about her expression. Something past the simple meaning of the words she used. Something like love, for how weird it seemed. She could tell there wasn't malice behind them. She could tell the Luna in the dream was enjoying them. She had to confess to herself, she enjoyed it too.
She moved her gaze lower to where the two ponies' hips were joined. Hers, or rather, those of the Luna in the dream, were reddened by the constant abuse, wet and slick with their combined juices. Celestia's thighs were equally wet, her own pussy dripping as the base of the strap-on tied around her hips ground against it.
The rhythm grew faster, drawing closer to a climax. Celestia's words transitioned to grunts and moans as she was overtaken by her lust, and Luna's moans rose in pitch and intensity. Luna's breath, the real one's, slowly grew deeper and rougher, her own hoof working faster and faster on her own pussy.
It was like every other time, the scene always identical to itself. The sounds, the smell, all building up to that final moment, that last howl of pleasure that would mark the end of yet another dream.
Her hoof moved away from her nethers, replaced by the frantic rubbing of her own magic, and Luna took another step forward, moving to her sister's side. Her pussy spread open by the tendrils of energy forcing their way inside her to thrust in and out, she lowered her neck, and whispered to Celestia's ear, "Fuck her. Keep fucking her. Fuck her like the worthless bitch she is, oh, yes, fuck-"
She broke away, her eyes snapping shut as her own orgasm drew closer and closer. She could still hear them, moving faster and faster, almost to the point of no return now. Her own hoof rejoined her magic, and she doubled her efforts on her sex. She was so close now, so close, just like the Luna in the dream, almost there, the sound she'd heard so many times before repeating one more time, and she would- she would-
Throwing her head back, screaming, juices spraying from her cunt as it pulsed around her magic, sparks of energy flying off from her horn, Luna came. Through several seconds of mind-numbing bliss, she sat there, shaking, her breaths ragged and throaty as she slowly returned to her senses. Quietly, as the blanket of pleasure dissipated from her mind and clarity seeped back in, she became once more aware of her surroundings.
A chill ran down her spine. There was something different about it. Something that had never been there in the dreams before. Her eyes, still closed from her climax, remained shut as she processed what was happening, nervousness creeping into her. The dream was still there. It had all been the same, and yet this time it hadn't ended. She'd seen them moving faster and faster, she'd heard the moans, she'd heard-
The realisation hit her like a whip, her memory finally rushing back, her brain finally processing the information it'd received while being overwhelmed by her own sexual stimulation. She had heard a scream. Her own. She hadn't heard Luna's, the other Luna's, scream.
With trembling, almost terrified care, Luna opened her eyes.
The scene was still there. Luna, the other Luna, was still on the ground, her face still contorted in a mask of pleasure. But she was motionless, seeming almost frozen in time. Luna lifted her eyes.
Celestia was still there. Smiling. Looking directly at her.
Much like her counterpart, Luna froze as she saw that.
Taking a step forward, moving past the Luna on the ground as she disappeared into smoke, walking up to the true one as the world around them slowly began to disappear, Celestia reached her sister and looked at her for one long moment.
Luna could have run. She could have teleported away. She could have woken up at that exact moment, had she wanted to. But she chose to remain there. And as her sister approached her, she simply stood there and swallowed, staring back at her.
Celestia took a deep breath, her smile widening. "If you enjoyed that so much," she whispered, "why don't you come to my room, and see for yourself what it's really like?"
The world around her disappeared, and Luna woke up with a jerk, drenched in cold sweat. She was in her study, a room on the first floor of the castle.
Not a minute later, and she was running. Through the halls of the castle, dashing through the corridors, rounding every corner with frantic urgency in her steps. Skipping up the steps of the staircases two or three at a time, bashing doors open or outright teleporting through them, almost slipping and falling on the marble floors. Rugs thrown askew by her passage, curtains tangled as she ran past them, flower pots just barely not falling from their designated positions. One or two maids and guards poking their heads out of their rooms to see a dash of blue further down the corridor, or a streak of mane disappear behind a corner.
Finally, her heart racing, her breath almost painful as it came in and out in sharp stings, she reached the door to her sister's room. She could have teleported there, but she'd chosen not to. As much as she wanted to, as much as she was desperate to go behind those doors, she was afraid. Afraid that what she was doing was just an impulse. Afraid that she would regret it. But neither the (admittedly short) time it had taken her to get there, nor the exhaustion, had dissuaded her from her intent.
With trembling hooves, her breath stuck in her throat, she pushed the door open.
"I've been waiting," Celestia said with a smile, welcoming her in. She wasn't wearing any of her royal garments, the usual gold of crown and collar replaced instead by the slick black of latex covering her hooves and legs, and of an intricately woven corset around her torso. Around her thighs, a large strap-on dildo, firmly held in place and already wet with lube.
Luna's gaze drifted lower, to the floor in front of her sister.
There lie a spreader bar with cuffs on each end, a collar, a bridle with annexed reins and bit, a coil of black rope and a riding crop.
She stifled a moan, biting her lower lip, then wordlessly threw herself forward on the ground.
Everything became a blur. There she was, on the ground, her wings and front hooves bound together by the rope around her back, her thighs held open by the spreader bar as her sister plunged in and out of her with her toy. Her neck arching back as her sister pulled and tugged at her reins, the sting of the crop as it struck against her ass, the scent of arousal filling the air. And it was real. It was hers.
Her sister's words resonated in her ears, her mind too flooded with sensation to grasp anything other than the basic concepts behind them. Degradation. Humiliation. Insults and remarks directed at her. And she loved every second of it. Because she could tell, behind the veil of appearance, that those words weren't out of hate. That there was love behind them, and a nervous tension to them. That this was what her sister wanted, and she was afraid of how it might have looked to her. And deep down, she'd come to realise that that was what she wanted as well.
Celestia's hips moved faster and faster, slamming against Luna's over and over, the dildo plunging in and out of the lunar alicorn's cunt. Her breaths were just as harsh as her sister's, her own pussy stimulated as it rubbed against the base of the toy, each thrust sending a shiver down her spine. She struck Luna's ass once more with the crop, then it escaped her hoof as she got lost more and more in the heat of the moment. She grabbed the reins in both hooves and pulled, pressing herself against her sister's back. Her mouth was on Luna's ear, but all that came out were slurred moans of pleasure-drunk ecstasy.
Luna felt her own orgasm fast approaching. Desperate to stretch that final moment of bliss as far as she could, she bucked her hips backwards towards her sister's. Her wings and front legs pressed between their sweat-covered bodies, the musk of their arousal filling her nostrils, her sister's moans and her own resonating in her ears, Luna came once again, the signs of her own arousal once more spraying from her nethers. She gave one final, loud cry of pleasure, then dropped to the ground, shivering in the afterglow, as her sister joined her with her own climax.
It was just like the dream Celestia had played through over and over. But as they opened their eyes, and looked at each other, the two sisters smiled. This time, it had been real.
Celestia slowly got back to her hooves, still panting. Her cheeks coloured a shade of crimson, she breathed, "I'm... Well, sorry I did all... that. I..." She gulped and gave a nervous giggle. "I wasn't exactly sure of how you'd take it."
Luna looked up at her, mane still messy, face covered in drool and sweat, eyes still hazed with lust. "...Shut up for once, will you?"
Celestia smiled and gently ran a hoof over Luna's back. "I'll go get some water."



"So that's how it went, huh?" Twilight asked, absent-mindedly pressing the button in front of her once again as she set her teacup down.
Beneath the glass table, Luna whimpered and jerked in her bonds at the shock of electricity the young alicorn had triggered.
"Yes," Celestia replied, pressing her own button and smiling as she saw her sister trying to suppress a moan as the toys buried in her holes began to vibrate more intensely.
Twilight looked down again. "Couldn't you have just... asked her? You two have been fucking since before she was sent to the moon, was it really necessary to go through that whole process of luring her through your dreams, plus all the time it took you to figure out how to pull that off, just to try out BDSM?"
Celestia giggled. "Oh, you should have seen what Luna did when she tried to get us to have a threesome. We ended up bedding the originally intended subject's grandson, she took that long to get the point across."
Twilight raised an eyebrow in amusement. "Well, I suppose one of the perks of immortality is getting to take your time with things." She pressed her button again.
Celestia nodded and did the same.
With a muffled cry, Luna came.
