Twilight Sparkle's eyes cracked open, no longer finding herself on her bed, but now floating in a pink world that consisted her mindscape whenever she decided to intrude on her thoughts. Not like she could do much anyway. She only had a remnant of the power she once had anyhow.
Midnight Sparkle's laugh was heard anyway, and she suddenly flew in behind the girl, earning a yelp of surprise. The demon smirked, her wings stalling behind her, able to float in this bizarre void. "Oh, Sparkle. It's amazing how much you lack a backbone."
"...Thanks..." Twilight murmured inaudibly, "What do you want now, Midnight? I know you don't have anything evil planned." she added, knowing that Midnight wasn't much of a threat.
The demoness smirked, "Oh, nothing too much. It seems as though your prized company is sleeping right next to you... Correct?" she asked, teasingly poking Twilight's nose.
Twilight sighed, "Yes. What about it? You haven't shown yourself since you suggested the experiment. So, what's different now?"
"Ah, always so oblivious to your hidden desires, aren't you?" Midnight teased, "Did you already forget I exist in the deepest, darkest recesses of your mind?" Twilight slowly shook her head, "Good. Now you should know what I am referring to now, and it has to do with the other Twilight that's embracing you as we speak."
Twilght bit her lip and stammered, "I-I have no idea what you're talking about..."
Midnight opened her palm, "Come on now, Sparkle. You're just too afraid to admit it, like before when I had to spell it out to you. Must we repeat ourselves?" she cooed, leaning forward and lightly twirling a strand of her good counterpart's hair. "It's a pretty dirty thought coming from you. And I love it." Twilight blushed upon hearing those words, her secret already having been spilled.
"Touched a nerve, I did." the demoness held back a laugh, "That is exactly it. You two haven't done anything... dirty since the experiment. And deep down you miss it."
Twilight crossed her arms, her face flushed, "A-And what if I did? Even so, I don't want my relationship summed up with coitus and sexual interactions everytime we see each other. We're just fine being together like this. The experiment proved a success, and there's nothing more to it than that. We're fine."
Midnight waggled a finger before wrapping an arm around Twilight, "Oh, I know that much. But a part of you misses it anyway. The passion, hearing her moans underneath you, the feeling that a reflection of you is doing it, it excites you doesn't it?" she asked, feeling Twilight shake, noticing her gaze looking away from the demoness as a result of what she said. "It seems I was right."
With a huff, Twilight spat, "What about it? Why do you care all of a sudden?"
"Cause I am getting bored of just watching two nerds beating around the bush when it comes to it. It would be interesting to see you take charge for a once." Midnight said, "And perhaps I could be of use to you like last time. Plus, you probably think she only agreed since you said it was an experiment..." she lowered her hand so she gripped Twilight's palm as tight as she could, catching the girl off guard once she felt her evil counterpart holding her hand.
Twilight was at a loss for words now, "S-So, even if I d-did say anything... Princess Twilight probably wouldn't want to."
Cupping Twilight's cheek, Midnight gave her doppelganger a devious smile, "Well, I guess it's time I proved you wrong."
The demoness held both of Twilight's hands and pinned her to what would've been the floor, their bodies still floating aimlessly in whatever this realm consisted of. "W-What are you d-doing, Midnight?" Twilight wondered, at a loss of words.
Midnight licked her lips, "Don't tell me you forgot about the times I taught you the birds and the bees, Sparkle. I think we're overdue to have a little fun with each other..." she purred and licked her lips, moving her palm so that she when she touched Twilight, her clothes vanished, surprising the girl, who shook under her evil counterpart. "Aw, don't be scared. I thought you enjoyed these little lessons." she cooed playfully, whispering into Twilight ear.
"A-A... Alright..." murmured Twilight.
And so, Midnight leaned forward, forcing her lips onto Twilight's. The girl receded, tingling at the sensation of Midnight's fingers tracing down her exposed body. Twilight shivered, feeling something in between her legs, letting out a moan as a result. Her evil counterpart already had her fingers invading her lower lips and the girl closed her eyes, surprised by how forward Midnight was now.
While she was doing this, Midnight's tongue slipped into her good counterpart's mouth, Twilight's eyes widening, but she allowed herself to mirror her evil self's actions, her tongue swirling and dancing with Midnight's own. Twilight held a hand over her doppelganger's neck, as the girl felt Midnight continue. She didn't want it to stop, as much as she hated to admit it.
A squeak escaped Twilight, feeling Midnight's fingers touch a sensitive spot in her clit. The two parted, their tongues hanging out and drool connecting them. Midnight looked to have a seductive smirk, proud of what she was doing. She wanted to make Twilight squirm in anyway possible, and she loved the sight of her good counterpart being a blabbering mess.
"Midnight..." groaned Twilight in a quiet tone, her mind still trying to process what was happening. Midnight never stopped playing with her counterpart's vagina, moving her fingers deeper. She wanted to hear her moan, to hear her scream in pleasure, "M-Midnight!" the girl called out again, louder this time. It wasn't to stop her, Twilight wanted her to keep going.
The demoness stroked a hand down the girl's bare back, rubbing and pinching her ass once she noticed it. Twilight moaned again, "Y-Yes..." she placed her own palms on Midnight's shoulders, never wanting to release their embrace. "Oh, yes!" she screamed. It was then Twilight climaxed, her body shivering even more and something dripped onto the demon's fingers as she still continued to play around. Another moan would've been heard, had Midnight not pushed her mouth into the girl's, muffling her in response.
This was exactly what she wanted. What the both of them wanted. And Midnight wasn't going to deny this was equally satisfying for her. To watch her doppelganger melt into a gooey puddle of pleasure. Midnight playfully licked Twilight's lip as they parted and nipped it gently, allowing the two of them to speak, "So, was it just as good as before?" the inner demon asked herself.
Twilight blabbered out, "U-Uh huuhhh..."
Giggling, Midnight cupped her counterpart's cheeks, "How about this? Tonight, I'll give you the chance to have this with that princess you love so much. To get in touch with your dirty side... Now that will be a sight to behold." she teased. "I won't be able to fully take control... But I could exacerbate your lust and desires... Wouldn't that be a neat little treat to have?" she wondered. "To finally gain what you've secretly desired?" she wondered, sitting on an invisible chair, holding her doppelganger's chin up with her fingers once she moved.
She saw Twilight's mindless, pleased nod, and snickered before she flicked a wrist, her palm engulfed in a blue flame and her blur horn glowing even brighter with a small aura, "Alright then. I guess this'll be one way to dominate you." before the dream faded, she shared one last kiss with her good counterpart, deciding to get the last laugh in before things got interesting.
Twilight snapped awake, her eyes glowing, revealing that Midnight had temporarily enhanced her lust. She could still feel everything that happened in the dream, but that didn't stop her want. Her desire. She noticed that Princess Twilight was still resting atop her. Her beautiful, slender form resting soundly with an arm wrapped around the girl, who seemed to have snuggled in the embrace.
"Nngh... T-Twilight...?" yawned the princess, awoken by the feeling the girl shuffle in their embrace. "Are you awake?"
Twilight whispered, "Yes..."
The Equestrian nodded off, wiping an eye with her free arm, "Oh... Are you okay?"
"Never better..." Twilight purred, leaning her head up so that she bumped noses with the princess, her hot breath pressed against the Equestrian's face, causing her to blush. "But you know what would make this night better?" she cooed.
The former pony blinked as she looked into the human's now glowing eyes, "W-What?"
"You..."
Without warning, Twilight kissed Princess Twilight. It was a little forceful, warm, and playful. The Equestrian knew something was different, yet at the same time... She hadn't seen this side of herself in a while... It was intriguing and actually sensual, and a second later, she melted into the kiss. The princess could tell something was off, and she could feel her doppelganger's hand reach into her pajama pants, her warm hands touching her skin.
Princess Twilight moaned in her human self's mouth, the girl never breaking their kiss and hiding her pleased smile. Twilight wanted her, to feel her, to kiss her, to hear her moans again. Then, she invaded the Equestrian's mouth, getting a muffled squeak as a response. Yet, there was no protesting. This was something the two of them had done before, and the former alicorn enjoyed the passion the two shared then, so she gladly opened her mouth and danced her tongue around the human's own to reciprocate.
The two remained like that, with the girl pinning her counterpart down with the kiss, their bodies pressed against each other, their tongues swirling and dancing in each other's mouths. It was then, that Twilight realized her doppelganger equally wanted this.
Alas, the Twilights separated, with the princess speaking first, "W-What brought this on?"
"I wanted you again..." Twilight whispered, pressing her lips to the Equestrian's cheek, then she lowered her head and began to caress her neck with kisses, "I miss this... I-Is that okay?" she asked in between kisses, raising her head for only a moment to look her shocked doppelgager in the eyes.
Princess Twilight smiled, holding the girl's shoulders, "Yes it is... But what about your parents or anyone else that could hear?"
Twilight nipped the Equestrian's neck and continued to peck her with kisses, reaching her hands for her pants and removing them, "It doesn't matter."
The Equestrian stifled a giggle, recalling the pleasure they had with the experiment. She noticed that her legs were exposed, her panties were dropped and she watched as the girl did the same to herself, removing all her pajamas. Princess Twilight was growing curious by her girlfriend's new behavior, but she'd be lying to herself if a part of her said she didn't want this. So, she also removed her shirt and unstrapped her bra, allowing the two bare doppelgangers to look at one another in excitement once they were ready.
Twilight stopped kissing the princess' neck and reached a hand inbetween the former Equestrian's thighs, with her feeling an evergrowing burning sensation there. The girl's warm fingers sent tingles down the princess' back with each soft movement. Then, she pressed her lips onto Princess Twilight's jaw, "I think I should show you something we haven't done since the experiment." she playfully said.
Then, the girl lowered her head and stuck her tongue out, playing with Princess Twilight's lower lips until she reached her clitoris. The princess bit her lip and held back a moan, gripping onto her pillow as hard as she could upon feeling the sudden volts of pleasure that dared to shake her entire body.
It was something the two haven't done in forever. Twilight continued to move her tongue around the former alicorn's vagina, her hands gripping her inner thighs for support. Her glowing eyes looked to the alicorn turned human and she winked, never ceasing her actions. Princess Twilight held back a loud moan and only settled for a squeak escaping her lips, "T-Twilight..." she said, the girl still going. The raging fire that was in her loins continued to grow with each precise movement of her doppelganger's tongue.
And Twilight was pleased to see her doppelganger squirm, yet see her look pleased at the same time. Then again, it may have just been Midnight's spell taking slight hold of her lust. The Equestrian continued to bit her lip, wanting to keep as quiet as possible, but it was proving to be a futile effort with each passing moment. "Twilight... Don't stop... P-Please..." she pleaded, holding back an orgasm.
The girl didn't say anything in response and continued to hit all the sweet spots, evident by Princess Twilight's groans and whispers. "Twilight...! Yes!" she let out an orgasm, one that probably breached the privacy of the walls. "Yes!" finally, she came and the girl could feel and taste every bit of it.
Satisfied, Twilight reached her head up and kissed the former alicorn, the taste of her evident felt in each other's mouths, not that the princess minded of course.
Once they parted, Princess Twilight murmured, "That was... W-Wonderful, me..."
"I'm glad you think so." the human said, kneading on of the former pony's breasts, her fingers tracing her areola before she lighty flicked her tongue on her nipple, the princess holding back another giggle, "I miss this so much. To only have each other like this." her other hand held her doppelganger's arm as she reached her lips back up to her jawline, planting soft, warm kisses to every inch of her chin before leaning for her lips again.
The Equestrian raised her hand and wrapped an arm around her counterpart's neck to pull her down more. It was quick, but still passionate. She reached a hand for her doppelganger's ass and gave it a light pinch, surprising the girl for once. Twilight gave her counterpart a half-lidded stare once she calmed herself, the green tint seen in her eyes leaving a glow in the darkened room. The two rolled around a little more as the princess groped her counterpart's breasts.
Their breathing was heavy, the adrenaline from eariler wearing down. Their bodies were still pressed atop each other, with Twilight straddling the princess underneath her. Princess Twilight giggled softly, "So... Are you ready for more?" she asked her lust-filled counterpart. "Cause I know I am..." he breath was felt on Twilight's chest. It only made her more excited.
Twilight nodded, lowering her head, desiring more from her doppelganger. Likewise for the Equestrian. And so, they continued for the night, letting their passion and love take hold.
With the rays of the morning sun shining on her, Twilight awoke, feeling a little colder than usual. Looking down, she realized she was undressed, and that Princess Twilight was in the same state as her, an arm held over her breasts, and a weird scent intoxicating the bed. That meant Midnight did what she intended.
Every vivid detail of the night flashed in her mind, every moan, every kiss, every movement, every word, Princess Twilight's surprised expressions and pleasure... She couldn't believe it actually happened, and she was happy about it.
"Twilight...?" said the Equestrian, awakening with her.
The girl blinked, "Huh... Yeah?"
Princess Twilight gave her doppelganger a soft smile, "You were amazing last night..." she complimented.
"S-Same to you... Whoa..." Twilight stammered, everything still flooding back in her mind.
A giggle was heard from the princess, "Maybe we should do this more often. You're kinda cute when you take charge."
Twilight blushed. The dynamic she has with her doppelgangers was strange. But she shrugged, deciding to leave it as is.
