Chapters Twilight opened her eyes, unable to feel her blanket over her body or the pillow she was resting on. Confused, she tried to sit up, but found herself floating in a pink void. Twilight gulped, remembering what these dreams meant, but she thought she got rid of them.
She propped herself upwards and looked around. "Oh no..." she whispered.
It was then, Twilight saw something come to light. It looked like her, yet she had an appearance of darkness, her eyes surrounded by blue flames, her hair spiked up and she gave a smug grin to her counterpart as she hovered in her spot.
"M-Midnight Sparkle?" gulped Twilight, "W-Why are you here? I-I thought I got rid of you."
Instead of talking, Midnight inched closer to Twilight, frightening the woman with each moment she got closer. The demon cupped her doppelganger's chin with one hand while wrapping her other arm around Twilight's waist, pulling her closer.
Their lips were inches apart from one another. Twilight was wondering what her counterpart was doing as Midnight began to gently rub her arm slowly, her surprisingly soft fingers giving the woman a tingling sensation on her limb. Her eyes went wide as the demon softly rubbed her cheeks for a moment and licked her lips in a seductive manner.
It was then, the gap between them closed.
Twilight gasped as Midnight began to kiss her. It was strange, the fact that she once threatened her and her friends and now this. But oddly, Twilight began to moan in pleasure, wrapping her hands around the demoness' neck and leaned into the embrace.
Midnight began to stroke her hands down Twilight's back, the woman twitching slightly. Twilight mirrored the demoness' actions and placed her hands on Midnight's shoulders. Twilight somehow was enjoying what was happening and closed her eyes, letting her former enemy continue.
The two parted for a second and Midnight smirked, caressing her counterpart's cheek lovingly. Twilight paused in her spot before Midnight leaned in again, pinning her onto an invisible wall within the void. The two embraced again, the woman hugging her counterpart with glee.
Midnight moved her head and Twilight felt something push on her lips. The woman opened her mouth and allowed Midnight's tongue to enter. It was a foreign feeling for Twilight, but it for some reason, it felt right. Twilight's tongue began to dance with Midnight's within their mouths. The two of them held each other and kissed for what felt like an eternity, but in truth is was only minutes. Twilight moaned again, feeling Midnight's mouth close.
The two parted again, a smacking sound heard as their lips moved away fast. Twilight's hands were on Midnight's chest and her counterpart's hands were on her chest.
It took a moment for Twilight to gain the ability to talk again, her cheeks red and flushed, "W-What was t-that about?"
Midnight chuckled, her laugh creating a small echo, "You know why , Twilight." the demoness vanished, leaving Twilight to ponder her words.
It was then, the girl awoke in the real world, her eyes snapping open and an alarm clock ringing next to her. Swiftly, she slammed a hand down on it, shutting it off. "Monday... School. School is good. Maybe I ate too much last night and my mind was having a reaction..." she muttered to herself, greatly confused by the dream. "Yes, that's it. Studying will take my mind off this. Studying always helps." she told herself.
The dream repeated itself each night this week. Each time, Twilight found herself in the pink void of a world and Midnight was there. The two would kiss before Midnight would vanish, leaving the woman with a vague clue as to why she was doing this. And those words did not help her in the slightest.
Twilight had tried to look up information on what such hints in dreams meant, but found nothing that could clue her in on what her counterpart was doing. It wasn't evil, or rogue at all. In fact, from the tone of Midnight's voice, it was almost like she was helping her counter with something, but Twilight just couldn't figure out what that something was.
It freaked her out a little. But Twilight admitted that she would be lying if she didn't enjoy the feeling. Every morning, she could still as if Midnight was actually there kissing her, a tingling sensation lingering on her lips. A small smile formed on her face at the thought, her face turning a little red at the idea.
"You okay, Twi?" asked a green and purple dog. Like Midnight, his ability to speak came about as a result of magic.
Twilight cleared her throat, "Y-Yeah, Spike. I am. Just thinking is all." she chuckled and answered in a fast manner.
Spike rolled his eyes, "If you say so. If you need to talk, let me know. I got a dog bowl with my name on with with food. After that, I'm coming upstairs to sleep."
"O-Okay, Spike." Twilight replied.
Twilight found herself in the void again, awaiting her demonic counterpart. At last, after a few moments she arrived and the events played out again for the fifth time for Twilight. Midnight closed the distance between herself and Twilight.
Twilight kept her eyes open this time and pushed her demon counterpart away, "Okay! Why are you doing this?!" she held Midnight by the shoulders and she licked her lips as a response.
"I told you already..." purred Midnight, wrapping her fingers around her counterpart's own. With a light shove she lay above Twilight, the two of them lying down on an invisible floor. "You want this, Sparkle. Don't deny it..." she cooed.
Midnight planted her lips on Twilight's forehead, the latter shivering at the touch. Twilight felt Midnight move her head down and kiss her cheek. "B-But why...? Why now ? What do y-you want?" asked Twilight nervously.
With a smug grin, Midnight softly kissed Twilight's lips, earning a quiet squeak from the woman. "Think about it, Sparkle. Who's the one person constantly in your head?" she caressed the woman's face, cupping her chin with her fingers. "And don't say Timber Spruce. I know that's a lie."
Twilight gulped, "T-The o-other..." she knew the answer but kept denying it despite deep down knowing.
"That's right. The other Twilight." Midnight revealed, kissing Twilight again, "I'm here because you're desperate. To fulfill the curious fantasy you secretly desired..."
"B-But..." whispered Twilight, getting cut off by Midnight kissing her again.
"Don't lie. Ever since you saw her you grew curious. She's like you, yet different." Midnight cooed, pecking her counterpart's cheek, "You wanted to.. experiment. Wonder what the feeling was like. But you're too scared to face the idea head on."
Twilight slowly nodded, stroking Midnight's back. "I-Is that why y-you're like this?"
"Of course. Now I live in the deepes recesses of your mind. To fulfill the fantasy you've wanted for months now. The actions I've done are a result of your mind. You wish to fulfill your curiosity."
Twilight closed her eyes, and pressed her lips to Midnight's own, opening her mouth. The two made out as Midnight moved her tongue within Twilight's mouth. After that, the woman parted from the demon, "Y-You're right..." she wrapped her hands around Midnight Sparkle's neck, feeling her lips on her neck.
"I know. I am you after all." Midnight boasted, closing the gap between them again.
"W-What do I do then?" Twilight asked.
Midnight chuckled, holding her doppelganger's hands. "It's simple. Conduct an experiment with her. I'm sure she'd figure it out what with the two of you having such a big brain. Take control of the situation for once."
Twilight gulped again, "Y-Yeah... I can do it that way. She's just so..."
Midnight raised a hand, "Save the gushing for later, Sparkle."
Nodding, Twilight grinned. "Y-Yeah... I'll tell her." she leaned forward and planted a kiss on Midnight's lips again, closing the gap between them and invading her mouth with her tongue. They parted, a smacking sound heard as they distanced one another. A trail of drool went into their mouths.
"I d-don't want this to e-end..." admitted Twilight.
Midnight giggled, rubbing her doppelganger's shoulders before moving her mouth down her neck, earning a moan from the woman. The two kissed one last time, wrapping their arms around their backs as they lovingly embraced one another.
They split apart again as Midnight whispered, "You know what to do, Sparkle... If you ever want to do this again..." she placed a finger and rubbed Twilight's lips, "You know where to go..." and with that Midnight Sparkle vanished for the night allowing Twilight to wake up.
Twilight awoke, sitting up on her bed, "M-Midnight was right..." she told herself in disbelief, "N-Now I just gotta figure out how to assess this situation. Oh... What have I gotten myself into?"
Despite being a figment of her imagination, Midnight Sparkle felt like an actual person at times for Twilight. Especially with what's been happening each night she found herself within her demon counterpart's presence in the pink void of her mind and realm. The two were embracing one another and Twilight could feel the demon's hot breath on her face.
The two were pinned on the invisible floor right now, with Twilight embracing Midnight by wrapping an arm around her back and the other on her neck. Midnight stuck her tongue out and rubbed a finger on Twilight's lips. "Did you do it, yet?" Midnight asked with a soft whisper to her doppelganger.
"Y-Yeah... Sunset wrote to her. S-She should be here tomorrow." Twilight revealed.
Midnight smirked, "Perfect..."
Twilight leaned her head forward and upward and closed the distance between herself and the demon. Midnight moaned, leaning into the kiss and played with Twilight's hair, twirling a strand as they closed their eyes. Twilight planted a hand on Midnight's cheek and turned her head slowly, seeking to taste her doppelganger.
The two separated, allowing Midnight to continue speaking, "With that big mind of yours, I am to assume you wish to do something, correct?" she rubbed her counterpart's cheek while she asked.
"K-Kind of..." whispered Twilight, letting a quiet moan escape her lips, "I-I just want to tell h-her about m-my recent curiosity and began a-an experiment... A-And hope she wants to a-agree."
Midnight smirked, putting a hand to Twilight's neck. "I see... Is that why you keep coming back here? To fulfill your urges in the meantime? I never took you for someone like that, Sparkle." she teased.
Twilight's face flushed red in embarassment, "M-Maybe... I-I'm just curious..."
"Heh. No shame in admitting it." Midnight out her hands on her good doppelganger's shoulders and began to rub them, causing Twilight to relax. "Perhaps I should prepare you to have some... fun." she purred in her doppelganger's ear, causing Twilight to shiver in small excitement.
Twilight frowned, "What kind if fun?"
With a chuckle, Midnight snapped her fingers. Once the sound echoed, Twilight noticed something. She felt a little colder than she did a minute ago. She looked down and noticed that her clothes vanished and moved an arm to her breasts to cover herself. "W-Why did you do that?"
Midnight looked bare as well, her features exposed. "To prepare you, Sparkle... You can never be too ready." she rubbed her good counterpart's arms and placed them around her neck. "I just wanna get you comfortable with... exposing yourself around yourself." she explained with a quiet laugh.
The two Twilights stood across from one another and softly embraced each other, Twilight not moving her hands from where Midnight put them. "I-I see..." the woman whispered.
Leaning forward, Midnight planted a kiss on her doppelganger's lips. The demon heard Twilight squeaked in pleasure, which pleased her greatly. She stroked Twilight's back with a finger as slow as she could, making Twilight shudder at the feeling. Midnight for some reason was enjoying this more than she had a right too, but it was fun teasing her counterpart at every opportunity.
Twilight began to push her tongue on Midnight's lips and intruded her mouth once allowed access. Their wet muscles danced in each other's mouths and fought for dominance. Twilight had embraced the idea of doing this with her inner counterpart ever since the first night where it happened.
Moving her hands around, Midnight started to fondle Twilight's breasts, cupping both of them in her hands. Twilight's eyes snapped open once she realized what was happening, but she refused to fight back and closed her eyes, continuing to lean into the kiss while allowing her doppelganger to have fun.
Deciding to mirror her dark counterpart's actions, Twilight gently rubbed Midnight's breasts as well, surprising the demon, who gasped in her mouth. She ignored the sound and moved a hand down Midnight's sleek back, reaching a palm for her counterpart's backside while her reflection did the same.
The two Twilights split apart for a second, and Midnight rubbed Twilight's lips with a finger, "My my... Getting to enjoy this aren't you?" she asked, seeing the drool trail bridging their tongues. Reaching her free hand out, Midnight loosened her counterpart's bun and loosened her hair.
Twilight nodded silently, desiring more.
"Alright... Let me show you some more goodness."
Midnight tilted her head and reached above Twilight's shoulder, planting her lips on her doppelganger's neck. Twilight gasp, melting into the feeling of Midnight sucking on her neck. "O-Oh..." she whimpered in pleasure, feeling Midnight place a hand to her cheek and rubbing it.
"You like that don't you?" teased Midnight, continuing to peck her doppelganger's neck lovingly, reaching a hand to her shoulders now.
"Y-Yes!" Twilight nearly screamed, "Keep going!"
Midnight raised her head again and put her index finger and thumb on Twilight's chin, licking her lips seductively. "Heh. If you think that was good. Wait until you see what I have planned next. Honestly, Sparkle, it's about time I let you out of your shell."
"P-Please..." begged Twilight.
The demon smirked, rubbing Twilight's breasts with one hand, giving her counterpart an arousing feeling. Twilight did the same to her own, wishing for the arousal to end.
Midnight lowered her head and reached for in-between Twilight's legs. The woman screamed in pleasure at the enjoyable feeling lingering in between her legs, feeling Midnight do things she wish she had learned earlier. She felt wet there and pleasured, as if this was a lesson to show her what to do.
Unfortunately for her, Twilight woke up. The feeling lingering in between her legs. She panted, every moment feeling like it actually happened. "W-Woah..." she gasped in amazement. "I-I can't b-believe that happened. And that I actually liked it."
She wiped the sweat off her head and looked at the clock. "Ten-thirty... Oh no! She's going to be here soon!" Twilight realized in a panic, wondering if everything Midnight showed her would come in handy what with what she wanted to do.
There was a dream that Twilight had sometime after the Friendship Games and transferring to Canterlot High before Midnight somehow came back to surprisingly aid her in her current conundrum. A mental image that she was slightly ashamed of having, yet it intrigued her at the same time. She did not fight this feeling, but has questioned it ever since she first had the dream.
It was right outside Canterlot High. In fact, for the most part, the dream mirrored the very first encounter Twilight ever had with her: the other Twilight. Her and her friends were just enjoying a picnic next to the statue, but it began to ripple before said girl jumped out in a hurry, rambling about why she wasn't around.
Twilight remembered the strange sight, the two of them locking eyes in great confusion. They were both still, wondering if they were just looking in a mirror. It took an introduction and an explanation, but after a few moments, the two Twilights were at ease.
But that was where the similarities of the memory and dream ended. Twilight blushed at the recollection. She had no idea where the idea came from, yet it interested her.
In her dream, she and her doppelganger walked closer instead of staying at a distance. Twilight could nearly remember every detail, a blessing and a curse at the same time.
She held the other Twilight's chest and her counterpart did the same to her. Few words were said in the dream, but to them, it was like no one else was there or watching. It was just those two. Twilight would move her hands to her former equine doppelganger's sides while the other Twilight would put her hands to her shoulders.
Twilight remembered what happened next. The two would lean forward to one another and close the distance between one another. Twilight's face flushed red at the memory of her idea, holding a palm to her forehead as though she was embarassed.
The two Twilights would remain like that for a minute, their hands moving all over each other as they melted into each other's embrace. The moment felt real, as though it was happening, like what Midnight was doing for her the past week.
It always ended once the two parted, a trail of drool bridging their tongues in their mouths and freely groping each other's breasts, a look of shock and pleasure seen on both of their faces.
'But why?' Twilight thought, stepping off the bus across the street from Canterlot High. 'Why do I feel like this? None of it makes any logical sense! I've become infatuated with myself!'
Finally arriving near the statue, Twilight sat down on the concrete step while waiting for her doppelganger. Her friends were busy with their own matters so that just left the girl on her own to stew in her own thoughts. 'Before she gets here, I have to figure this out before I make things awkward... well, more awkward.' she thought, 'Now... The dreams began sometime after I met her. Now why would I have these dreams about myself?'
Twilight rested her arms on her legs, 'There could be a couple reasons... maybe it's my overly eager curiosity over such a conundrum that brought it in my head in the first place. The idea of satisfying a doppelganger has been an idea in many heads, perhaps I never knew I thought about it until the opportunity showed itself?' she suggested to herself, putting a hand on her chin, 'Another reason could be for narcissistic reasons. Perhaps the idea of being with myself pleased me, and I just didn't realize it.' she shook her head, 'No, I'm not like Trixie. I wouldn't think of myself that high and mighty. At least, I don't like to.'
'And then there's the last theory I can come up with.' Twilight added, 'She's me... Yet she is so different in every way but appearance and name. I'm a nerd and she's... a princess! We couldn't be anymore different. I-I think the reason for these feelings are because she's still me, but at the same time different enough to be a different person. Maybe I just want to learn what these feelings mean from someone who can share them.'
Twilight's gaze was raised at the sound and sight if light beaming out of the statue. A moment later, from the ripples, came a girl that looked like her. Same purple-skin tone, hair color and eyes. The only differences were her clothing the fact that her hair wasn't tied in a bun, reaching down to her back and the lack of glasses.
"Twilight?" the doppelganger asked.
"Y-Yes?" Twilight replied, blushing at the sight of counterpart.
"You wanted to see me, right?" the Equestrian Twilight replied, a sincere smile on her face. "To be honest, I was waiting for this."
"Y-You did?" gulped Twilight.
"Of course. To know my doppelganger? Why wouldn't I want to do this?" her doppelganger wondered with a small chuckle.
Twilight chuckled too, "R-Right..."
One bus ride later, and the two Twilights finally returned to the girl's home. The former pony looked around at the house and asked a simple question, "Where's everyp-" she cleared her throat, "Everybody at?"
"At work for today." Twilight explained, gesturing for her counterpart to walk upstairs, "Shining took Spike to the vet. Ever since he gained the ability to speak, he's shown his distaste for it, though."
The two chuckled, "I can see that." the former Equestrian said. "Do your parents know about me ?"
Twilight nodded, "They do... It took some convincing, but the evidence was there. If they were to come back, it's only a matter of explaining things."
The Twilights found themselves in Twilight's bedroom and sat down on the girl's bed, sitting across from one another. The native Twilight gulped, doing her best not to panic, 'Okay, okay... She's here now. Don't panic. Everything will be fine.' she told herself in her head as fast as she could.
Princess Twilight tilted her head and raised a brow, "Are you okay, Twilight?" she asked sincerely, putting a hand on her human counterpart's shoulder.
"Y-Yeah, I'm fine. W-Why wouldn't I be?" Twilight asked with a nervous gulp.
The Equestrian pursed her lips, "Because your cheeks are red and you look like your shaking. Is everything fine? I can come back another time if you want." she suggested, putting her palm to her doppelganger's forehead, feeling its warmth.
"N-No, don't leave." pleaded the human Twilight.
"Okay... Sunset used the journal to reach me. She said you wanted to talk about something." Princess Twilight elaborated.
Twilight's eyes widened, 'Oh no... W-What do I do now? Midnight didn't prepare me for this!'
The bookworm shook her head, "F-forget it... You'd just laugh and think it's stupid." she shrugged off in a saddened tone, looking down on her bed sheets.
Princess Twilight extended a hand and held her counterpart's palm in her own, making Twilight squeak in surprise at the feeling, "Twilight. I'm not going to think it's stupid and there is no way I would ever laugh at you. I promise. But I need you to be honest with me, okay?"
"R-right." Twilight mumbled.
"I won't think any less of you, I promise." the princess assured with a sincere grin.
'Do it, Twilight. You won't get another moment like this! Like Midnight said.'
Without thinking, Twilight pressed her lips onto Princess Twilight, surprising the Equestrian, judging by the gasp. A moment later she closed her eyes, melting into the kiss. The girl embraced her counterpart for a second before parting as fast as she kissed the princess, the both of them opening their eyes slowly.
Twilight's eyes widened and she stood up, clenching the sides of her head, "Oh no no no... What have I done? I completely screwed things up!" she practically screamed, tears running diwn her face. "I'm such an idiot..." she sulked to herself.
"Twilight..." the Equestrian said in a calm tone, standing up and trying to calm her doppelganger and putting a palm to her cheek. "I'm not mad at you. Okay? I promised you that much." she sighed softly, "B-But why?"
Twilight sniffled, "W-w-why?" she asked. "Because you're everything I'm not. You're more social, more mature, a-and you're a princess! I-I guess I just liked that about you." she wiped an eye dry while the princess helped comfort her. "To see what I could become, I guess I fell for you once we met, my curiosity got the better of me again..." another sniffle escaped her, "I guess I am an egomaniac."
"Is that why you wanted to talk to me? About this?" at the girl's nod, the Equestrian continued, sitting the two of them down, "I'm not better than you, Twilight. Nobody's perfect. Least of all me. But you being you, and not a carbon copy of another Twilight... It makes you unique. And I see someone unique in front of me. Don't ever feel inferior, Twilight. You have a group of friends who like you for you." she faced her doppelganger, who leaned on her shoulder. "And I'm flattered , really I am... To know you think of me like this..."
"S-So, you're not mad at me?" Twilight questioned.
Princess Twilight smiled and cupped the girl's chin with her index finger and thumb. She slowly leaned in and Twilight began to panic over what was going on, but she let it happen. Butterflies began to fly in the girl's stomach as she felt the former pony's warm breath on her face, embracing her Equestrian doppelganger as the distance between them closed at last. The feeling was everything she hoped for. Princess Twilight hugged her counterpart while the human held the former pony's shoulders. It felt like an eternity for the two Twilights as they sat still, savoring each other's taste.
At last, the Twilights separated, giving each other a half-lidded stare. Princess Twilight giggled, "Did that answer your question?" she askee, holding her doppelganger's cheeks.
Twilight's lips quivered into a smile and she squealed, "Yes!" she cheered, hugging her doppelganger.
The girl gave her counterpart a quick peck on the mouth, repeating the action in excitement. Princess Twilight was confused st first, but she returned the favor in kind, kissing her doppelganger back each time. The princess grabbed Twilight's waist as she continued to kiss her, planting one more kiss on her lips, a longer embrace this time.
A quiet smack was heard as they stopped, gazing into each other's eyes lovingly. Princess Twilight wrapped her fingers around her human counterpart's own, the girls smiling and blushing at the feeling of their soft hands. "I-I'm so happy with how this turned out..." cooed Twilight, leaning on the former pony's shoulder.
Princess Twilight smiled, kissing her doppelganger's forehead softly, earning a giggle. She lowered her head and gave Twilight one last kiss. While their lips met, Twilight gently stroked her counterpart's arms, reaching for her shoulders and then held her back. Princess Twilight placed her palms on her human counterpart's face, melting into the kiss.
The two gave each other some distance, needing air. "Me too." replied Princess Twilight, seeing Twilight hug her again. She returned the hug. "Is there anything else you want to talk about? I think I might stay here with you until I head back."
The girl slowly nodded, facing her equine counterpart and adjusted her glasses. "Actually..."
Princess Twilight blinked, wishing to listen intently to whatever her doppelganger was about to say. Twilight twirled a atrand of her hair awkwardly and began to say, "I-I was t-thinking about something for a while..." she admitted, pushing the bridge of her glasses up.
The Equestrian gripped her doppelganger's hand, remaining silent to allow the girl to continue, "It was..." she sighed, "An experiment of sorts basically." she pulled a lock of hair behind her ear nervously, "The experiment... Well..."
Twilight gripped her Equestrian counterpart's shoulders, "It's rather... I-intimate . That's mainly the reason why I called you here, b-besides revealing how I truly feel. I wish to learn more about intimacy with oneself." she revealed, "I'm sorry, really I am, but... I just had to ask."
Princess Twilight smiled, stroking the girl's arm to ease her worries, "I would be okay with that. It would be a good learning experience for the two of us." she agreed, kissing the human's forehead.
"Thank you..." whispered Twilight.
"What would it be about, out of curiosity?" the Equestrian Twilight asked, gazing into the eyes of the other Twilight.
"W-Well... I-it would involve the two of us in rather.. alluring situations. I w-want to learn about this with someone I can trust. And..." Twilight quickly pecked the princess' cheek, "I can trust you, since you are me. But I've been interested in this topic since I first met you." she revealed, her face turning red at the revelation to her counterpart, who she tried to hide this information from for long enough.
Nodding, Princess Twilight replied, "I can see why you would want to do this. Tonight, we'll begin to plan what we'll do then. The experiment can begin tomorrow in that case. If you want, we can visit my world if you eish to learn more there."
"I... I would like that." mumbled Twilight, hugging the Equestrian. Princess Twilight smiled, returning the embrace. "Again. Thank you for understanding."
Night fell for the two Twilights, who had just finished wrapping up planning their secret project: dubbed The Twilight Experiment . Luckily, the matter of two of them being in the same household really wasn't a problem. After all, Spike knew of the situation, and with him being a talking dog, it honestly made the situation more believable than it sounded.
The two were now asleep, Twilight resting in the arms of her princess counterpart. Spike sleeped on the floor this time, wanting the space for himself.
Within Twilight's mind, she found herself in a realm she was beginning to recognize. The pink void that hosted the lately surprisingly helpful demon that practically encouraged her to push forward with this idea. "I wonder why I'm still here." she said to herself, flowing admist the dream world.
Appearing out of thin air was Midnight Sparkle, who crossed her arms with a smirk, "Well well well. It looks like you actually did it, Sparkle. I'll admit, I'm actually impressed."
"Um..." Twilight was unsure of what to say, noticing her demon floating closer to her. The familiar feeling of her fingers reaching for her cheek made her shudder nervously.
Midnight remained in her spot, "What's wrong, Twilight? Do you not want me doing this?" she teased, holding a finger to her good counterpart's lips, "After all I've done? You wouldn't have gotten this far had it not been for me."
Twilight gulped, "Y-You're right, Midnight. I want t-to thank you." she put her hands to the demon's back and removed the gap between them. Midnight gladly returned the favor and tilted her head, emjoying the taste of her good counterpart's mouth. The two separated from each other a moment later.
"I know. And it looks like you got yourself a little intimate project tomorrow. It seems rather complex for plain sex."
Twilight blushed, letting go of her counterpart. Midnight laughed and rubbed the girl's shoulder with one hand, "I jest, Sparkle. Honestly, you can't take a joke. To think this is what I'm reduced to now. Your spiritual guide. I'm only doing it so you don't look so darn pathetic." she admitted, rubbing her temple.
"And I said thank you." huffed the girl, turning away from her demon self.
Midnight giggled, leaning into Twilight's ear, whispering something, "I can still help you, you know. Princess Twilight wished to do a couple things with you. It's only fair I got a hand in this."
Twilight rolled her eyes, "Fine."
"Then what are you waiting for?" with a snap of her fingers, Midnight Sparkle removed their clothes again and loosened Twilight's hair, gently stroking a hand down her counterpart's backside, the girl moaning in pleasure at the feeling of her rear getting pinched. Midnight then planted her lips on Twilight's neck and pinned her down, landing on an invisible floor like before. Feeling her breath on her neck excited Twilight as she opened her mouth and lolled her tongue out.
Twilight grabbed the demon's head and kissed her, her tongue reaching into Midnight's mouth. The two made out as Twilight moved a hand to Midnight's breasts, fondling them. The spirit gasped before moaning, closing her eyes as she deepened the kiss the two of them shared.
Separating her mouth from Twilight's, Midnight wipes the saliva off her mouth and smirked, licking her lips. "Do you want me to repeat what I did before?" she asked.
Twilight moaned and pleaded, "Y-Yes... Please... Show me..."
"Very well."
Midnight began to peck Twilight's lips, moving her mouth down, softly kissing her neck, chest and moved down to her breasts, rubbing them playfully. She finally reached the outer lips in between Twilight's legs, her desired spot. Midnight leaned in, and Twilight felt a surge of adrenaline overtake her body, making her shake a little.
The feeling of Midnight's tongue made Twilight feel hot down there more than usual. Feeling the wet muscle invade her lower lips was exciting. Midnight did everything to make this more enjoyable, showing her how to do this. It was strange how it was her demon that decided to help at this time.
"A-ah!" Twilight gasped, feeling Midnight's tongue reach deeper. "M-Midnight, p-please... Never leave me."
Midnight paused, "Wouldn't think of it now. You need me more than ever, Sparkle." she raised her head and gave the girl one last kiss, sharing what she tasted with Twilight. When the two parted, Twilight opened her eyes and instead of seeing Midnight, she saw her Equestrian counterpart in the dream.
This snapped Twilight back to reality, awakening from the surprise in her dream. The girl noticed two purple limbs wrapped around her body, the other Twilight holding her in her sleep apparently. The sun shone through the window and made it hard to see for the girl and she shielded her eyes, turning her head and dropping her head across from the princess. 'Wow. She looks pretty like this.' she complimented, seeing her snoozing counterpart. The girl then began to breathe heavily, remembering what was happening today and she froze.
'Okay. Calm down, Twilight. Today is when the experiment begins. No pressure. Other than making love to your doppelganger from another dimension. I hope I don't screw this up.' she thought.
Experiment I: Human Intimacy
Twilight stretched her arms, deciding to get up and shut the curtains so that the sun doesn't continue to blind her. Her double awoke as well, moving her arms back. "I thought you had school?" she mumbled out as she stretched.
The girl closed the curtains, blocking the sun's light from entering the window. "Spring Break." she yawned to her Equestrian counterpart, "We have a whole week off."
Princess Twilight sat up, "Oh. Is your family home?"
"Only Spike is. I just have to feed him." the girl answered, putting on her glasses, which she grabbed from the dresser placed next to her bed. She blinked a couple times before looking down, seeing the dog still asleep. Twilight saw his ear twitch and an eye open, "Spike?" she called out.
"Yeah? I'm awake, Twi." Spike yawned.
Twilight smiled, "You want something to eat?"
"Heck yeah! Man, I wish I had hands... And were taller sometimes so I could get the food." Spike admitted.
The girl petted the dog and he smiled, "I know. But do you mind if you stay downstairs for a bit today after I get your treats? The two of us wish to conduct a few... tests and I don't think you want to be involved with them."
"Got it, Twi. You two ever need the company, I'll be up in a jiffy!" Spike saluted a a paw on his forehead.
Giggling, the girl led the dog downstairs to give him a few treats, "I know. That's why you're the best dog."
Princess Twilight heard the door creak open, seeing her doppelganger step back inside. Twilight slowly closed it behind her and she said, "Okay... Now it's just us. Alone. Are you sure you want to do this?" she asked again.
"I'm sure. For a while, I thought about this too." admitted the princess. "Would this fall under incest or masturbation? It's an odd enigma that's got many people confused."
Twilight sat back down her bed, "I'm not sure. Perhaps there's a term out there to describe our situation?" she suggested. "But we spent all night planning this. I just want to make sure you're in this, I don't want you to think you have to do this." she added, seeing her double nod. "So... How should we begin?"
Princess Twilight sighed, "Well, we decided to test the waters by kissing again."
"O-Okay..." gulped Twilight.
Deciding now was the the time to begin, the doppelgangers leaned forward. It felt as though a spark was ignited in their chests and butterflies were in their stomach. The Twilights held each other close, enjoying the taste of one another. The counterparts held each other like that for a few minutes, sitting still. But then, they separated, giving each other a half-lidded stare.
"Wow..." gasped Princess Twilight.
"Y-Yeah..." agreed Twilight, "D-Do you want t-to be m-more intimate?"
Nodding, the princess wrapped her double close and kissed her again. This time, the Equestrian felt something push on her lips and she nesrly gasped before closing her eyes. She complied and opened her mouth, allowing her doppelganger's tongue to enter her mouth. The girl proved to be dominating in their little dance and the princess tilted her head, moving deeper into the kiss, pushing her wet muscle into her human counterpart's mouth.
As much as she hated to admit it at first, those strange intimate nights in her head with Midnight proved to help Twilight in making this little pet project a success. But she remembered that for now, they were only on the testng stage: testing the waters in a way to see if there truly is a spark between them that could reach a deeper level.
Princess Twilight slowly raised a hand, and rubbed her counterpart's arm, stroking downward on it before wrapping her fingers around her hand. The soft touch of the former alicorn made Twilight moan in her doppelganger's mouth. Their tongues continue to swirl in each other's mouth before finally parting. Their tongues were hanging out of their mouths and a very thin trail of saliva could be seen hanging from them, showing their connection.
The two Twilights gave each other a wide eyed stared, surprised by how much they enjoyed that. Their faces were as red as an apple and they felt warm. They noticed they were holding hands at this point, but they chose not to part. "U-Uh..." stammered Twilight, the girl's mouth hanging open.
"W-Was it too much?" Princess Twilight asked.
Twilight shook her head, "N-No, that's not it. I liked it... Really. I'm j-just surprised by how much I did." she explained, tightening her fingers more around her doppelganger's own.
Sighing, the Equestrian spoke, "I-I'm sorry, I've never r-really been this intimate with anypony on my world. S-So all of this, it's all new to me."
"Me too." Twilight said back, not counter her recent encounters with Midnight.
Princess Twilight uncurled her fingers from Twilight's hands and held her cheek, "D-Do you want to move on now?"
"Y-Yes, please." stammered the girl.
Instead of reaching for her doppelganger's lips, Twilight lowered herself to her jaw. "T-Twilight..." quietly squealed the princess, her counterpart's hot breath and caressing lips on her chin threatened to melt her into jelly at how sensual the feeling was for her. She shut her eyes in pleasure, enjoying the feeling. Hearing that made Twilight continue and peck her cheek, reaching down for the Equestrian's collarbone.
"O-Oh..." moaned the former pony, with Twilight's mouth on her neck, moving her lips up and down, a quiet smack heard a few seconds apart. She raised her head and saw Princess Twilight's pleased smile, her mouth hanging open and drooling in sensual pleasure from what just happened.
Out of nowhere, Princess Twilight groped her double and pushed her down on the bed, shoving her mouth onto Twiight's own. She laid atop the girl as she repeated what she did, slowly moving her lips across the human's jawline. The princess's hands were stretched out and holding her doppelganger's own. Twilight let out a yelp upon Princess Twilight reaching her head down to her neck, her tongue slowly moving upon it.
"D-Don't stop, T-Twilight..." Twilight whispered, the princess pecking her neck again before reaching for her counterpart's lips again, moving in for a deep kiss.
Princess Twilight whispered back, "I don't want to..." she leaned on the girl's chest, "Do you want to move on to the next part?"
"Yes..." Twilight agreed, leaning upwards to kiss the Equestrian one more time. She couldn't believe how good that felt, neither could the princess. Yes, they kissed before, but not quite like this. They continued for another moment before letting passion consume their every movement.
And now, Twilight found herself in a predicament. One that she was hoping wouldn't end anytime soon.
She was straddling herself.
Sitting on top of her and holding her was Princess Twilight, who gazed down at the girl with a surprisingly lustful stare. Her tongue was hanging from her mouth and she distanced her head away from her doppelganger's face, awaiting her response.
"S-So..." the princess gasped.
Twilight repeated, "S-So...?"
Princess Twilight cleared her throat, "D-Do you want to move on to the next stage? To b-be more physical?"
The girl slowly nodded, "Yes... B-But it'll require us to... Undress ourselves." she quietly gulped, grasping the Equestrian's hands as she spoke.
The Equestrian princess nodded, understanding the situation. She raised her arms, removing her shirt and tossed it on the floor on the side of the bed, just next to the nightstand. The human Twilight mirrored her actions and threw hers on top of the former alicorn's. She then removed her glasses, folding the hinges and placing the spectacles on the nightstand next to the alarm clock. Finally, she reached a hand to the scrunchie in her hair, removing it, allowing her hair to flow freely from its bun.
For the Equestrian Twilight, it was like looking straight at a mirror. But she didn't mind that. Here she was, holding her beautiful doppelganger underneath her, exposed in a way that only the two of them can comprehend. Silence was passed among the two, their faces warming up at seeing one another like this.
Twilight slowly reached a hand up to the princess' cheek, "Shall we... continue?" she asked curiously, unsure of how to move on at the moment, breaking the silence at last.
Princess Twilight cleared her throat, "Y-Yes..." she whispered.
Lowering her head, Princess Twilight continued the experiment, pressing her lips back to her doppelganger's. Aa they kissed, the two Twilights caressed one another, moving their fingers up and down each other's bodies, their hands seemingly moving of their accord and their actions not thought of.
Twilight stroked her right hand upward, seemingly touching something round and rather plump. Opening an eye, she realized she was rubbing the princess' breast. "Mmph." she heard the former pony moan in her mouth, liking the feeling. Deciding to get more physical in this experiment, the girl decided to rub the side before reaching for the bra string, unstrapping it at last. They separated, allowing Princess Twilight to do the same to her.
"Are you o-okay with this?" Twilight asked her double.
Princess Twilight nodded, "Yes... I think so. Wow, um... I guess we're becoming more physical then..."
Being the first to take action, Twilight held the Equestrian's breasts and began to rub them, Princess Twilight gasping out in pleasure at the touch of her counterpart. The former alicorn then brought up her own palm and kneaded the girl's own breast, sending tingles down Twilight's spine. The princess leaned forward and stuck her tongue out, kneading her doppelganger's nipple, her wet appendage doing wonders for the girl's adrenaline.
The touch of her Equestrian double's tongue on her areola forced the human to mumble incoherent words, babbling nonsense as Princess Twilight continued to tease her nipple, her other hand rubbing her other breast. Once again, she was at a loss of words over what was happening.
Princess Twilight moved her head back, a soft pop sound heard as she gazed in the eye of her double. Twilight had some drool running down her face, wishing the feeling of the princess on her breast never leaving. "K-Keep g-going..." she pleaded in a hushed tone, her mind scrambling over the foreign feeling, "P-Please..."
In a haze, Twilight pecked Princess Twilight's mouth again, moving in for a deep kiss. It was short, exciting, but they parted almost instantly, the girl choosing to move her lips down to the Equestrian's chin, her lips caressing her jawline. Princess Twilight closed her eyes and allowed her counterpart to continue, her mouth hung open and a whisper of babbles escaping her own mouth.
Moving downward, Twilight had planted her lips on nearly every inch of the Equestrian's neck, sticking her tongue out occassionally for the fun of it. She finally reached Princess Twilight's breast and began to do what her counterpart did. Her tongue circled around the former pony's areola, and she was surprised by how good it felt, "T-Twilight... W-What are y-you.. Y-Yes..." she wondered, babbling over the surprisingly strange moment of passion.
But alas, Twilight leaned back slightly, ending the moment. The two sat up, giving each other a lustful stare, the two of them nearly about to become a puddle of goo over their intimacy, that is, if their minds hadn't already gushed down. The only thing that was shared among the two was silence and a very loving embrace. While they hugged, the two Twilights reached down for their pajama pants and seeked to remove them. They felt something wet in their panties, no doubt from the moments of excitement that just passed.
Their chests heaved, quiet panting heard from the two of them. "D-Do you want to do this...?" Twilight asked her counterpart.
Princess Twilight, "T-Twilight... I've never been more sure."
Princess Twilight pushed her doppelganger down again, holding her wrists before gently wrapping her fingers around her palms. Twilight loved being straddled by her doppelganger now, she couldn't deny that. Not when she not only realized how bizarre the idea was, but how beautiful she looked.
While her mind ran with this, she didn't realize their panties had been removed. In a rush, she rolled Princess Twilight around on the bed and was now lying atop of her. She pecked the Equestrian's lips as she raised a hand, ticking the princess's chest, moving downward until she reached her desired spot. Something pulsing and yet in between the former pony's legs.
Twilight moved her fingers in Princess Twilight's loins, the princess having no idea of what her doppelganger was up to, but a second later her mind gushed, "Sweet Celestia..." she gasped under her breath. The girl would be lying if she said she was experienced in this sort of physical activity, the only source of moments like this before today were her dreams with Midnight, which gave her a vague idea of what to do.
While Twilight moved her fingers in the Equestrian's nether lips, the princess kissed her in a haze. Her lust and adrenaline consuming her for the moment. Princess Twilight's tongue invaded her double's mouth, loving every moment of what was happening. Twilight's fingers felt wetter with each second, no doubt pleasuring the former pony. The princess gently kneaded the girl's breasts with her fingers, exciting the girl even more than ever.
Princess Twilight never wanted her counterpart to stop. The feeling was too good, her fingers still gently massaging her vulva. She was nearly about to cum, another moan threatening to escape her lips. At last, Twilight felt something dripping onto her hands and stopped at once, the juices staining the covers of her bed. She'd clean it up later. But for now, Princess Twilight paused their kiss, panting. Twilight took the moment to slowly and seductively lick her fingers, giving her doppelganger a fun wink.
Satisfied, Twilight made out with the princess one more time, sharing the juices she just tasted, opening her mouth and dancing with her tongue. A smack was heard as they parted, their chests heaving up and down, clearly not used to this kind of interaction. The former alicorn was the first to speak, "Woah..."
"Y-Yeah..." the girl agreed. "D-Do you want to h-have a turn?" she offered.
Princess Twilight pursed her lips and wrapped her arms around her double, lying on her hip as was Twilight. "Actually... I was hoping to move on to something else now. Then." she gave a lidded, lustful stare, "Once we begin that, then I'll have my turn."
Twilight knew she was talking about the second part of the experiment. It was going to be weird at first, but despite her oncoming transformation, she was going to have more than her curiosity satisfied.
Now they had to clean up and get to the portal.
Experiment II: Pony Phase
Ripples appeared on the magic mirror, revealing that something was about to exit from the other end. One moment later, Princess Twilight jumped through, landing perfectly on her hooves and took a glance at herself, seeing that she was back to her original alicorn self.
After she appeared, Twilight came through, falling flat on her face, a thud and a grunt heard. "Ow..." she muttered, her chin resting on the clear floor.
Helping her doppelganger up by holding a hoof, Princess Twilight couldn't help but admire her counterpart's appearance. She looked just like her, minus the alicorn wings. Her hair was in a bun and her glasses made her stand out more, and the alicorn couldn't help but look in awe at the former human.
"I'm sorry," the alicorn muttered, reeling her mind back, "I forgot you weren't used to this."
Twilight blinked, slowly getting on all fours, "I...I'm not sure how you Equines walk like this." she muttered, holding the princess' hoof as tight as she could for leverage.
"It comes naturally to us Equestrians, but since you're a human, I didn't think that part through." the alicorn admitted sheepishly and a little embarassment.
Twilight cleared her throat, "No, it's alright. I just need time to... adjust is all." she assured with a wave of a hoof, accidentally making herself fall again, not used to her new situation.
"So... Do you live here by yourself?" the girl asked.
Princess Twilight looked at her doppelganger, "No, Spike and my student Starlight Glimmer do as well. But they're in the Crystal Empire visiting Sunburst and Thorax. It gave me the time to visit once Sunset wrote to me to see you for... well..."
The former human was surprised by the major differences in this world. She was a princess, had a student, and there were other kingdoms. At least she still had Spike no matter what. It seemed to her that certain things remain constant, which relieved her a little.
"Follow me. I'll give you a quick tour of the castle." Princess Twilight insisted.
Twilight nodded, took a step forward and then fell again. "Oops." the princess frowned, reaching a hoof out for her now equine counterpart to hold on to again.
"Thank you..." the former human groaned, "I just need time is all."
"Alright."
It took some time, and a lot of walking, but it seemed Twilight got to see the whole castle, from the many guest rooms, library, lab, closets and even bathrooms. That sounded strange when referring to herself, but the former human knew that her counterpart was meant for something like this. Twilight smiled, holding onto her counterpart's hoof. The princess said there was one last spot to go to before... the second phase of the project.
And Twilight was even beginning to learn to walk as a pony. It honestly took a bit, and she was still stumbling a little, but adjustments were made in how she moved, and it worked better in the advice of her Equestrian self.
The alicorn lit up her horn and opened up a pair of doors that were in front of them. Inside was a giant bed and a door that led to a large balcony. "...And here is my bedroom."
Twilight blinked, "...Is this where...?"
Princess Twilight slowly nodded, knowing what her doppelganger was going to say, "...Yes." she admitted, her face turning red. She put a hoof to her forehead, "...My mind got a little curious is all. I'm sorry if all this is making you uncomfortable."
Twilight frowned, shaking her head, "N-No, I'm not uncomfortable at all. We planned this out t-together. I remember that much of the plan. It's just... It's quite a change for the both of us. Well, mostly for me."
"I understand." the princess mumbled, "We can wait until your more comfortable in this form if you wish." she suggested.
Twilight replied, "No... I'm ready. We can conduct the next phase."
Silently nodding, Princess Twilight stepped backwards near the bed. Her doppelganger followed her trail and watched as the alicorn wrapped her hooves on her shoulders, prompting the two of them to stand on their hindlegs as Twilight placed her forehooves to the alicorn's sides. Their muzzles began to flush red and grow warm around their cheeks. Princess Twilight was clearly not used to such intimacy with another pony, and it kind of made her excited, knowing she'd get to do this with herself.
For Twilight, it was yet another foreign experience. Here she was, a unicorn, and now being held in the hooves of herself. She gave her alicorn self a soft smile, feeling rather safe in her grasp. If there was anyone at this point she could feel content with doing such activities, it was herself now.
The two gazed into each other's eyes lovingly, wondering who was going to make the first move in this mutual experiment. Princess Twilight put a hoof to the unicorn's cheek and smiled, sitting on the side edge of the bed now.
At last, she moved forward, closing the gap between the two of them until their lips met.
Twilight's eyes snapped open. Her doppelganger's lips felt different this time, almost a little fuzzy on her own. But this did not deter her from deepening the action, and tilted her head, closing her eyelids. It felt almost exotic for the former girl, but that was the reason she was enjoying it.
Princess Twilight stroked a hoof onto the unicorn's mane lovingly and pulled her back once her hoof reached her barrel, lying on the bed now. Her doppelganger yelped in surprise at the sudden yank, but this did not stop her from deepening the kiss.
The two rolled around, never breaking the kiss as they moved about on the bed. Now, Twilight lay underneath her alicorn counterpart, her head cushioned on a pillow. Princess Twilight placed a hoof on her doppelganger's chest, tilting her head as she deepened the kiss a little more.
A smack was heard and the two distanced each other's muzzles. Twilight's mouth was agape, "W-Wow..." she whispered, putting a hoof to her tingling mouth.
Princess Twilight raised a brow and frowned, "Did you l-like it?" she asked.
Twilight gave her alicorn counterpart a quick peck on the lips to answer her question, parting a moment later. "...Yes."
The princess giggled, "Alright. S-So, shall we...?" she trailed off, wondering if her counterpart was having the same train of thought.
The unicorn wrapped her hooves around Princess Twilight's neck and pulled her in for another smooch, this time opening her mouth and pushing her tongue onto her doppelganger's own. The Equestrian moaned and opened her mouth in kind, stroking her hooves down the unicorn's chest, leaning further into the kiss.
Alas, they separated and the princess cleared her throat awkwardly, "S-Shall I... Do what do you did...?" she asked slowly, moving her gaze downward. Twilight swiftly nodded upon hearing her words and insisted she did.
Knowing what her counterpart wanted, the native Equestrain grinned and lowered her head down her doppelganger's body. Princess Twilight pecked each part of Twilight's body, sending tingles down the unicorn's body with each touch.
At last, Princess Twilight found her desired spot. Unsure of what to do, she moved her head in and stuck her tongue out, rubbing it on Twilight's clit. Twilight nearly screamed in pleasure, trying her best not to jump from the figurative volts being sent in her body. The alicorn's tongue ran through the former human's nether regions and she felt and enjoyed every little movement.
"Y-You're do-doing good..." Twilight whispered out, putting her hooves to her chest.
The Equestrian remained silent and continued her actions, tasting her doppelganger's... Love juices as she described it after the first experiment. A musky stench overtook the room in a matter of moments, coming from the both of them, but they actually found pleasure in the fact that they were satisfying each other.
Princess Twilight stopped at last, seeing her doppelganger cum leak onto the bed sheets. She licked her lips, tasting her brief experience. She smirked, leaning her body forward and placing her head on her unicorn self's fluffy chest. She inhaled sharply before exhaling, blinking in confusion, gazing through her new lover's glasses, seeing her stunned face. The princess wondered, "Did you... Did you like that?"
Twilight wrapped a hoof around her doppelganger's back and another to her muzzle, giving her a quick kiss before parting. "Yes..." she moaned. To repay her counterpart, she stroked a hoof down her body and reached for her cutie mark. Twilight nervously pinched it in hopes of arousing her counterpart as a quick repayment. Princess Twilight squeaked upon feeling her flank get squeezed. Twilight smiled sheepishly, hoping that her actions were right.
The Princess, despite the sudden movement, gave her counterpart a lustful stare. "How... Different..." she gasped, feeling another pinch, "Didn't think... the cutie mark and flank was an... erogenous zone." she admitted. To test her theory, she rolled her counterpart on the bed, earning a squeak and mirroring the former human's actions, reaching her hooves to the cutie mark and lightly squeezing it.
Twilight yelped, not used to this. "I-I see..." she saw Twilight's alicorn wings and wished to continue this pony experimentation. The unicorn lightly stroked a hoof on the alicorn's spine while lightly kissing her neck. This suddenly caused the princess' wings to unfurl upon instinct.
"T-The wings..." Princess Twilight moaned.
Twilight didn't hear what she said and moved her muzzle to the feathery wings. Princess Twilight recognized this action as preening. She had no idea it could feel so... erotic. Twilight began to lightly move her mouth on the tip of the wings, sending tingles down the alicorn's spine. Twilight closed her eyes, hearing Princess Twilight's satisfied moans, "W-Wow..." she gasped out, loving every moment her doppelganger was preening her.
Twilight did this for both wings and noticed that the alicorn stomped a hoof on the bed, not used to such behavior. The unicorn noticed this and frowned, "W-Was I not correct in doing that? Did... did that annoy you?" she asked in an unsure tone, hopong she didn't make her counterpart feel uncomfortable. Princess Twilight's wings twitched, unable to move back into place due to her current erotic position, not that she minded it of course.
The alicorn kissed the unicorn once again, raising her hooves to the former human's face. Her head tilted and deepened the kiss. Twilight's eyes closed as did her counterpart. They moaned, sitting up, tasting each other, the latter now feeling a bitter taste, no doubt from the princess' actions. A moment later, Twilight wrapped her hooves around the alicorn and pushed the two of them back on the bed, pushing her tongue into the Equestrian's mouth.
Twilight's tongue rolled around her doppelganger's own, the latter returning the favor in kind. They remained still like that until the princess separated them. "Y-You... I loved it..." she gasped out at last.
With a relieved smile, the unicorn muttered, "Good." Twilight shuffled the two of them on the pillow. Princess Twilight rested her head ln the unicorn's chest again while Twilight gently stroked a hoof on her Equestrian counterpart's back. The princess giggled and kissed Twilight's cheek.
"Do you wish to enact the final experiment once we're ready?" the princess asked tnrough a hushed whisper.
Twilight slowly nodded, "Yes." she cooed, nuzzling her doppelganger's mane, "With some adjustments to the portal it could be done." she planted her lips on Princess Twilight's forehead.
The princess agreed and closed her eyes. Two experiments in a day and the Sun still wasn't down. Twilight held her alicorn self lovingly and looked out the window, hoping that the third and final part goes as smoothly as before.
Experiment III: Final Changes
Princess Twilight looked to the mirror, seeing the modifications done to it. There were crystals placed nearby the machine she used to keep the rift between the two worlds open. The alicorn hoped that they'd serve their purpose in this experiment. She sat down, and looked over the notes, making sure they matched what she did. With a relieved sigh she looked up to the mirror, waiting a moment for her counterpart to finally finish her part.
At last, not too soon after, a familiar purple-skinned girl accidentally tumbled through the portal. She groaned lightly, not expecting such a trip. "I'm okay..." she assured. Twilight stumbled back to her toes as fast as she could. This time she wore a lab coat, which was buttoned up and her hair was already down, not in its usual bun. "Okay... I-It looks like it works."
Smiling at her doppelganger, Princess Twilight raised a hoof, "I'm rather surprised it did. The fact we can keep our forms like this is quite a feat. But this should only be a temporary thing. It'd be easier if we kept our transformed states."
Twilight nodded in agreement, "I agree." her eyes kept gazing to another direction. The princess knew where and her mouth formed 'oh' once she followed where her eyes went.
"You... Want to... get started already?" Princess Twilight wondered curiously.
"Kind of." admitted Twilight with a light blush. She took off her glasses, reaching for the nightstand.
Once they were back in the bedroom, the alicorn took the time to close off the windows and blinds, giving the two counterparts privacy. "Okay..." exhaled the princess. "We should be clear again. I guess we can," she inhaled, "Begin the final part of this experiment. This one is an unknown anamoly though."
The two Twilights sat each other down on the bed. The human Twilight removed her lab coat, revealing her bra and she removed her skirt, dropping it onto the ground with the white coat. She was unsure of how to continue the action. Unsure, she placed her palms on the alicorn's shoulders.
Princess Twilight whispered into her doppelganger's ear, "Do what you want. It will be fine. We're doing this to test the waters, remember?" she reminded her.
Hearing the assuring words of the pony, Twilight reached her hands to the straps on her bra and unstrapped them, allowing that to fall on the pile as well. She admitted, that she was getting a little excited, yet nervousness played a part in her emotions.
'I'm a human performing coitus with a pony that is me.' the girl thought, 'I-I can't mess this up.'
Placing her doubts aside, Twilight kissed Princess Twilight. The sensation felt different this time. The girl could still feel the fur on her double's lips, but the alicorn could feel the softness of the human's own. It was a unique feeling for them to say the least. Princess Twilight leaned deeper into the kiss, parting for a second to lick her counterpart's lips before moving back in.
Twilight tilted her head and rubbed a hand down the pony's mane, pushing her forward so they were lying down. The girl pressed her hand onto her doppelganger's chest as she felt the princess' tongue move in tandem with her own.
Alas, they separated as they held one another close. Twilight and Princess Twilight gave each other a wide eyed stare, unaware of how deep they were into the moment. Twilight's arms wrapped around the mare's neck.
"So... That's what it feels like." muttered Princess Twilight, holding a hoof to her lips.
Twilight closed her eyes, "D-Did I ruin it?"
"N-No, it's just... Huh." Princess Twilight murmured. She placed her hooves on the human's chest and held them firmly, earning a loud squak from her counterpart. Twilight reached for her muzzle and planted a deep kiss.
Any excuse they had to continue was gone, now lust replaced those curious emotions, wishing to move on anyhow. Twilight moaned, feeling her doppelganger's hooves push on her breasts, giving her a sensual feeling unlike anything before. Her hooves were soft, yet rough in their movements.
Twilight straddled herself and moaned as they continued making out. Princess Twilight lightly flicked her tongue as they moved, dancing around the human's own wet appendage. The girl reached her hands to the princess' shoulders, holding her close.
Deciding to continue the experiment, Twilight gently moved her hands to Princess Twilight's wings and lightly stroked a finger on her feathers. Instantly, the alicorn's wings unfurled as they separated their lips, the human continuing to lightly rub her fingers on the tip, causing the mare to moan in pleasure.
Now excited, Princess Twilight said no words as she moved her hooves around Twilight's breasts, caressing them as lightly as she could. Loving the alicorn's touch, Twilight smiled at the feeling and her eyes nearly rolled to the back of her head in pleasure, feeling the mare's hooves lightly rub her nipples and areola.
Twilight continued to play with the princess' wings as Princess Twilight moved her head forward, bringing her mouth onto the human's chest, sucking on her nipple slightly. The girl had to stop for a moment to process what was happening, but she didn't want it to end. "O-Oh..." she moaned in a hushed tone.
With a soft popping sound, Princess Twilight moved her head back, a satisfied grin and drool running down her mouth seen. She licked her lips, reaching for the girl's mouth again. Twilight reciprocated the action and continued caressing the mare's wings with her fingers. Her hands unconsciously slid down the pony's curves and found her flank, around the cutie mark, which she rubbed in a circular motion. Princess Twilight was heard moaning, never stopping the kiss.
Using her magic, Princess Twilight lowered her doppelganger's panties, not breaking the kiss in the process and she got a good look at her lower lips before closing her eyes again. The two leaned around, to where the alicorn lay atop the human.
Princess Twilight stopped the kiss, her human counterpart wondering what she was doing. She saw the alicorn lower her head in between her legs. Something sparked within the girl, feeling her pony counterpart's tongue down there. Every movement sparked a volt of adrenaline in her. Princess Twilight moved her head in a little more, reaching her tongue into the girl's vulva, tasting her cum with each precise movement.
The girl loved every moment. Everywhere her counterpart licked, she was about ready to melt. Who knew that her pony self could make this feel so good? That was why they had the experiment in the first place.
Twilight could barely contain herself as Princess Twilight raised her head and moved it so she was staring lovingly into her double's eyes, feeling her cum leak down onto the bed once she was finished, leaving a small stain. But that didn't matter to them. "H-How was that?" the princess asked, wiping a hoof on her muzzle, removing anything that drooled from her mouth.
Leaning forward, Twilight gave her doppelganger a deep kiss. As they separated, the girl gave the mare a few extra pecks, showing that she wanted more, but she wanted to answer her counterpart.
"Wonderful..." Twilight let out in a squeaky tone. She playfully shoved her doppelganger and with a giggle, wrapped her arms around the pony again, feeling Princess Twilight stroke a hoof down her long hair. The girl was once again lying over the mare, who didn't mind the change.
Twilight pecked Princess Twilight's face, planting her lips on the pony's own for a second before leaning toward her neck. The girl began to softly kiss her double's neck, almost sucking on it. Her hands started to stroke the alicorn's chest, playing with some of the fur hairs. She felt weird at first doing this, but she found the skin and bit a small tuft of fur, ticking the pony and making her giggle lightly as she melted into the embrace.
The girl brought her head up and had an idea. The princess didn't mind kissing her counterpart again. But she was a little confused, feeling a hand grip her horn. She felt her doppelganger's hand rubbing it in an up and down motion. This sent shivers down the alicorn's spine, not used to the sensual feeling on her horn.
Suddenly, sparks of magic bursted out of her horn, which prompted the girl to stop. In excitement, the princess deepened the kiss and moved her tongue down, licking the girl's mouth as they parted, saliva seen dripping from their mouths. They wiped their lips clean and gazed at each other. The two of them were panting, no doubt from the brief moments of adrenaline wearing them down with each precise moment of pleasure. They were unused to this. Princess Twilight was obviously curious, "H-How did you..."
"I-It looks like..." Twilight stammered, her face turning red. The mare's face did as well, knowing what she was referring to and she put a hoof to the girl's mouth,
"Oh." was all the princess said. She felt wet and noticed the musky smell again, this time coming from her. But she had no energy to continue. "S-Should we wrap up for tonight?"
Twilight nodded, "Yeah. This was... fun." a smile formed on her lips. "We learned a lot about our anatomy."
The alicorn agreed and kissed her double on her lips, "And ourselves. We'll record everything in the journal after a small nap. After changing the portal and that, I think we could use a moment to rest."
The girl nodded, moving so that she was on her back. Princess Twilight smiled, moving the two of them under the covers with her magic, wanting to rest. The alicorn leaned on Twilight's chest and she wrapped her arms around the pony's barrel, giving her a soft peck on the forehead. The human looked back and knew there was one matter to attend to.
A certain dark doppelganger in her head.
Conclusion: Midnight Visit
It had been a day since the two Twilights had finished the Twilight Experiment. Once they decided that it was a success, Twilight returned to her world, while her alicorn counterpart had certain matters to attend to before visiting in the morning. Luckily, they had already deemed their little experiment a success. Twilight smiled to herself, remembering the intimate moments the two shared, learning that they did have a connection, and she wanted to have more of that.
As much as she loved her doppelganger, Twilight was a little relieved to be on her own tonigh. As it allowed her to finish business with something that's been plaguing her mind since the beginning of all this and was the very catalyst for this experiment in the first place. The girl laid upon her bed, wrapping the covers over her body and she finally closed her tired eyes, taking a while to fall asleep, ready to make one last visit to that person.
Midnight Sparkle.
When her eyes opened, Twilight once more found herself within the endless pink void, and also Midnight's realm of her own mindscape. It had been a place she's seen times before. When she feared her, and now... she welcomed her presence. As of now, Midnight was no threat and she was forever grateful of Sunset's help in making sure that was truly the case in the first place.
Now, the girl turned her head and noticed her dark counterpart slowly hovering towards her. Twilight didn't do anything and remained frozen, awaiting a reaction from the inner demon.
But before Midnight said anything, she gently wrapped her arms around the girl's neck. "Well well. Look who decided to come back." Midnight pursed her lips as she feigned sadness, "About time, and I was getting rather lonely in here." she teased, giving Twilight a quick kiss. The girl closed her eyes before separating the two of them.
Twilight wrapped Midnight's fingers around her own, stroking her hands around her arms until reaching her palms. "Okay, Midnight. I have to ask... Why help me?" she asked, confused over the action of who she considered to be an enemy.
A devious smirk was seen on the demoness' face, "Oh, wouldn't you like to know, Sparkle?" she poked Twilight's nose playfully before placing her hands on her good counterpart's shoulders. She spun Twilight around, catching the girl off guard as she let out a quiet yelp in surprise, feeling Midnight massage her.
The demoness chuckled darkly whike she massaged Twilight's shoulders, "Jeez, you're tense. Your lucky I gave you that confidence boost. Being stuck in a body this shaky and constantly nervous is a sin in itself." Midnight leaned in to whisper in Twilight's ear, "But then again, can you say you hated what we've done together?" she pecked Twilight's cheek from behind, spinning her good counterpart once again so they were face to face.
Twilight stammered nervously, "That... T-That d-didn't answer my question."
Midnight giggled and groped Twilight's breasts, "Do you want me to, Sparkle? I can tell you enjoy this... Would you want that mystery spoiled already? Heh, very well." she cooed, hearing the girl moan as Midnight's hands rubed her boobs. "Let's just say... I'm getting bored being in your subconscious. Even if I can't take your body, I may as well have some fun."
"F-Fun?" Twilight gasped out.
The demoness moved her hands to cup Twilight's chin, "Ease up, Sparkle. I'm not plotting anything. If I am to be here, I may as well do something. I've been able to enter your dreams and decided you needed a push in admitting those curious feelings of yours for the other Twilight. May as well do something in here." she stuck her tongue out.
"S-So, why are you still doing this?" Twilight asked, blushing. She could feel the aura around Midnight's face and fake horn heating up her face as she got closer.
Midnight planted a deep kiss on Twilight's lips, the girl not objecting and instead choosing to reciprocate her demoness counterpart. Twilight hugged Midnight tightly, feeling her doppelganger's fingers stroke her back downwards, reaching for her rear and lightly pinching it, causing her eyes to snap open for a second at the sudden feeling, but they closed again. Twilight deepened the kiss, running her fingers through Midnight's long, wild hair.
Twilight moved away from the demoness, seeing her smug smile as they separated. Midnight smirked, "Just admit it, Sparkle. You're going to get lonely with your counterpart being on her world most of the time. And you don't want me to stop this."
"But--"
Midnight raised a hand before the girl could make an objection, "I'm in your head, remember? I can sense these emotions. Deep down, despite your initial protests, you want to keep what we have." she embraced Twilight by the waist with one arm while holding her hand with the other, pushing her in closer to her. Their hot breath could be felt on their faces. The two remained like that, with tingles being sent down Twilight's spine, feeling Midnight getting ever closer to her lips. It was almost teasing in a way, but Twilight didn't fight the feeling she was having.
Pulling Midnight forward, Twilight closed the distance between them. She moved her palms all around Midnight's body, feeling her curves, her hips and finally grabbed her breasts. They were larger than her own, which confused her, but Twilight circled her fingers and squeezed them a little. Midnight was surprised by her doppelganger's direct approach, not that she minded of course. It felt good to not have to start things for once.
Twilight and Midnight's tongue danced. To Twilight, this was all real. It was like having Midnight next to her. Her tongue lightly squirmed around the entity's own, feeling Midnight's wet appendage circle around hers. Midnight's fingers managed to squeeze her ass again, causing her to gasp in her doppelganger's mouth.
Midnight tilted her head as she and Twilight hugged one another to push the two of them closer. The feeling of their breasts pressing against one another greatly increased their arousal. They pushed on each other more, never wanting the moment to end.
But they separated once more, but before parting for good, Twilight planted one last peck on her doppelganger's lips. And Midnight flicked her tongue on Twilight's bottom lip. They gazed lovingly at each another in silence, holding the other in a deep embrace. Twilight had her arms wrapped around the back of Midnight's neck while her dark counterpart held the girl by her waist.
At last, Midnight broke the silence, "So, you really want to end this?"
Twilight slowly shook her head and blushed, "N-No... I don't... That was wonderful..."
Midnight chuckled, raising her hands so that she stroked Twilight's cheeks, the girl gently placing her palms upon them. "Very well, Sparkle. A shame it's almost morning. But... maybe we'll do things a little more dirty ?" she teased, seductively winking at her doppelganger, who was beginning to fade back to the real world.
Twilight's eyes snapped open, hearing the annoying ring of an alarm. She reached for the snooze button and sat up. Her face was flushed and she wiped some sweat off her forehead. "Oh no... I'm gonna be late!" she said, referring to meeting with her doppelganger over a supposed 'date night'.
