There they stood, Twilight Sparkle, one of the four princesses of Equestria, pinning her human counterpart to the couch. The two of them looked each other in the eye, both of them blushing profusely as you could practically feel their hearts beating throughout the entire room.

'How did things get to this point?' the human Twilight thought as past events began flooding back into her mind.

***

Earlier that day, Princess Twilight had come to the human world to visit her human counterpart, as per their schedule that they had set up after having first met some time ago. They had discussed their usual routines and things that had been going on lately, but Princess Twilight seemed to shuffle about in her seat every now and again. It was subtle enough to go unnoticed by others, but Twilight had developed a keen sense of vision during her time researching, and managed to notice it.

"Is everything alright?" she asked, feeling a tad bit worried.

"Oh, everything's alright" Princess Twilight practically strained herself saying, her face quickly covered in sweat, and her entire face flushed. Something wasn't adding up here, and Twilight could see it as she tried to look away from her.

"I think I should get you some ice or something else to help-" Twilight mused as she tried to step up, only to be grabbed by the wrist and brought down with a gasp, her Equestrian counterpart looking at her with a serious look, wanting something out of her. The next thing she knew, she was directly under her, their faces mere inches apart as she could feel her eyes piercing her very soul.

Without any warning, Princess Twilight pressed her lips to her other, letting out soft moans as she thrashed and struggled about on top of her, both of her hands going across her back and practically digging into it. Twilight hadn't any idea what had gotten into her all of a sudden, but at the same time, she didn't want her to stop.

After a little bit of a struggle, she managed to get the princess of friendship off of her long enough to ask "What is wrong with you!?" in a worried tone, her breath ragged.

"I'm sorry. I felt as though I was in heat when I left, but now, my body is hotter than ever. Please, I need this" Princess Twilight answered with a pleading tone as she started to suckle upon her counterpart's neck, making the glasses-wearing girl moan out with a completely red face. She could feel her hands going across her back again, unclipping her bra through the fabric of her shirt and then bringing up the rest of her shirt right away.

Her supple chest flesh was soon attacked by the princess' mouth and hands, kneading and suckling it to the rhythm of their hearts beating. At this point, Twilight had more than welcomed her affection, holding Princess Twilight's head in place as she continued to sexually assault her entire chest. Admittedly, she loved this more than she should've, making her feel light-headed as she suddenly felt her counterpart stop and stand up.

Twilight struggled to undo her clothes, but after a few seconds, she stood before her other wearing nothing more than her long socks, trailing small licks and kisses down her body as she brought her hands before the human's skirt, pulling it down and admiring her thin figure for just a moment. Afterwards, she immediately started trailing her tongue around the front of her crotch, each stroke of her tongue dodging her pussy and making Twilight writhe.

"Oh, quit teasing me" Twilight moaned, the princess looking up at her with a sultry grin and chuckling as she stood up and repositioned them both so that she could lie on top of her.

"I'll take care of you if you take care of me" Princess Twilight said, spreading the other Twilight's folds into a glorious bloom as she inhaled her aroma. Meanwhile, Twilight could feel the princess' heat radiating off of her cunt like a furnace, leaning forward to lick it and make the latter squirm a little, giving off a little moan. Knowing what spots made her writhe about in a pleasurable agony, Twilight soon repeated her action, now spreading her lower lips apart as she kissed the glistening folds.

Princess Twilight was no slouch when it came to pleasuring another mare, figuring that she would know her own body better than anyone else. Sure, this wasn't a case of clone beings willing to pleasure one another, but it was still two identical Twilights. That alone made the princess believe that she could pleasure her the ways she would pleasure herself. She slowly traced her tongue around the warm pussy lips, tasting a sweet essence secreting itself from her body.

The two tasted one another for what felt like hours, both of them managing to increase the pleasure levels between one another by moaning directly into their love tunnels. Just when it felt like one of them would cum, Princess Twilight suddenly rolled off, looking quite frantic.

"Quick, tell me you have something long, plastic, and double-ended" she begged, taking the scientist by surprise as her pupils went to pinpricks.

"I'm not sure how you know, but it's in my closet" she answered rather shyly, watching her counterpart rush off towards her bedroom in slow-motion, her beautiful body swaying majestically and managing to make her heart practically stop beating. Soon enough, she came back with a double-ended dildo and the two rushed into position on the couch.

The two Twilights quickly pushed the heads of the dildo into their individual entrances, both moaning out lewdly at the mere feeling as she felt connected. Slowly, they pushed their pelvises closer together, the feeling of the purple magic rod suddenly feeling thicker as they got closer to the hilt. Princess Twilight grabbed hold of the other's breast, which was soon met in kind as they tried to help one another climax quickly.

They scissored and thrust into one another as their moans formed an excellent chorus with one another, Twilight's glasses being taken off so that they could kiss once again, their tongues dancing across the air as all managed to go white. Soon, both Twilights grit their teeth and groaned out, feeling the floodgates break down as they both exploded in a torrent of their own cum, letting out pleased moans in perfect harmony.

Princess Twilight removed the dildo from the two of them carefully, then lied down on top of her counterpart's body, both sweaty, out of breath, and feeling ragged as they shared another passionate kiss between one another.

Spike, Twilight's loving dog, looked at the strange display carefully, having been woken up by the sounds of moans and thrashing about as she watched his owner in her sleep, kissing her pillow with her arms wrapped around it. Feeling as though he had seen enough, he barked a few times, trying to awaken her before she did something incredibly weird.

Eventually, Twilight woke up covered in cold sweat, her heart and mind racing as she looked around, not finding her Equestrian counterpart anywhere in her dark room.

"What on earth...?" she thought as she turned on the lamp on her nightstand and donned her glasses, sitting up with a sticky sensation between her legs. It didn't take her long to realize exactly what had been going on, but it didn't open up a lot more room for her to think closely about how she felt about herself.

"Is it technically sex or masturbation...?" she muttered to herself as she went off to change into something dry and clean up. If she ever saw herself, she'd have to wonder just how exactly she'd face the other her without bringing it up, or worse, trying to pull something. Oh well, that could wait for later.

Author's Note

Can you honestly say that you've never had the same idea for a Twilight on Twilight fic?

Anyway, this is just something I thought I would get on paper before it completely disappeared. I can only really type when I'm inspired by something, and of course, I was inspired by the third movie.
