Being reborn into a Nightmare Moon cult was weird.
You don't imagine that's much of a shocker. There wasn't exactly a consensus about what happened after death back on Earth, but you were pretty sure that 'end up in a world of magical ponies' wasn't an option. Or, shit, maybe it was. You hadn't exactly paid attention in Sunday School, and it didn't much matter now. All you know is that one moment you were stepping onto a bus and then you'd slipped. The next time your eyes opened, it was to a world of giant, colorful ponies.
It had taken a shamefully long time to realize they were only giant because you were a baby pony. There was a good day or two where you were getting ready for some Gulliver’s Travels style bullshit.
Coming to terms with being a baby pony took a little longer than a couple days, but it happened. That was kind of the thing about freaky stuff - it can't stay that way forever. One day you wake up and freaky is your new normal. Desensitization or whatever. And once you were done being freaked out, there was a lot of cool stuff to look into.
Sure, there was a lot to miss about being human - opposable thumbs and meat were definitely near the top of that list, what you'd do for a real hamburger and not just one of these weird hayburgers - but being a unicorn was pretty awesome. You had magic. Like, actual, real magic.
The downside of ending up in a completely different world where magic is real is that it's a completely different world where magic is real. There's a lot more to learn than how to live with hooves. Pony social cues and body language alone were a pain to pick up - you blame it on the whole having been a bipedal predator thing - and you were getting a little tired of being constantly surprised by random mythological things actually existing.
Speaking of being surprised by myths, apparently the dark god your town worshipped was, y'know, back.
The cult thing was a little off putting at first, but it hadn’t been all that different than a normal religion. Maybe it had begun as a band of diehard rebels willing to oppose Princess Celestia
till the end, but that was a thousand years ago. A thousand years is a really long time. Their descendants were just normal ponies by now. Normal ponies that happened to have a few odd traditions and worship Nightmare Moon, but still. Sure, all the chicken blood and ritual sacrifices could get a little awkward, but it was mostly harmless.
Or so you had hoped, until the return of Princess Luna, who was apparently Nightmare Moon but not? Supposedly, she had been cleansed by some legendary artifacts you had never heard of called the Elements of Harmony. Which was great, except that if half of what the cult had to say about Nightmare Moon was true, there was no way things were that simple. And it wasn’t like you could just traipse into Canterlot and throw scanning spells at a Princess. Instead, your too-smart-to-live ass figured you could scan the place where she had been defeated.
Which was why you ended up here, in the Castle of the Two Sisters, with a bleeding leg and face to face with Nightmare Moon.
The bloody leg wasn't her fault, though. That was because past you was an idiot. All, 'So it isn't controlled by pegasi, what's a little bad weather going to do?', and 'Oh, how bad could the Everfree be?' It turns out that it was pretty bad. Like, manticores bad. You were lucky to have escaped with only an injured leg.
"If you don't mind me asking," you started, as you watched her finish tightening the makeshift bandage around your flank with her magic, "What happened to the whole eternal night thing?"
The mare winced, and you felt a little bad about bringing up her defeat. "We might gotten too excited. We hath had some time to think about it by Ourselves, and... All the plants would die, wouldn't they? We want everypony to appreciate our night, not starve." She said with a sigh. "Thou mayst stay here till thy leg heals, shouldst thou wish."
"Thanks, but are you sure?" you ask, shifting awkwardly. You had seen a few pictures of her - the cult had a few, although they were very... dated, artistically. Joints didn’t work like that. - and they'd certainly not exaggerated her height. She was the tallest pony you'd ever seen. "It'll probably be a few days."
"Aye, We are sure. Thy company wouldst be much appreciated," she admitted as she drew closer, her tail flicking. You stiffened as your loins stirred, and a sort of realization began to dawn. "We hath been quite lonely since Our defeat."
Alongside being the tallest pony you'd ever seen, Nightmare Moon was easily the most... well developed mare you'd ever seen. Her ass was the kind of thing you’d expect to start a cult. You gave her a nervous smile, while you tried in vain to keep your eyes off her flank. "I'm glad our conversation is more interesting than silence, then."
She took a final step forwards, and you nervous as you were, you didn’t want to look away. "Who said anything about conversation?" she whispered before her lips met yours.
A hoof found its way behind your head to pull you closer, and you're distantly aware of yourself doing the same. Your lips part and her tongue slips into your mouth.
She mewled with want when you eventually pull away for breath. You were not much better - your boner throbbed, and you could barely think of anything but the taste of cinnamon on your tongue.
The two of you crash back together, and before you know it you're on the ground.
Her fur was like silk to you, and your hooves roamed her body. Somewhere along the line you ended up on your back, with Nightmare Moon straddling you. There's a moment where you wonder why the two of you have stopped, and then she goes down and thought leaves you.
"A-Ah," she moans, and you're little better. She's wet and hot and tighter than anything had right to be. And then she starts bouncing her hips on top of you and all you can do is grip her and
buck underneath her.
"M-More," she pants helplessly as she slows, her legs barely able to support her desire, "More!" You bite your lip and surge upwards, flipping her onto her back as you start to pound away. Her wings scrape uselessly at your back as she arches into you. You're screaming her name as you bury your muzzle into her mane, and stars explode behind your eyes as you ejaculate in heaving spurts.
The two of you lie there for a while, curling into each other. You do not know how long you stayed like that, but eventually you broke the silence.
“I’ll… need to leave, eventually.” She stiffens next to you and tries to look away, but you stop her with a kiss. When you pull away, you can see the tears in her eyes. “Come with me?”
You didn’t end up sleeping at all that night.
Author's Note
This is my first time writing anything even vaguely erotic, so I doubt it's very good. Figured I'd post it and hope for criticism - thanks for reading if you made it this far <3
