The Night Shall Last Forever

Nightmare Moon groaned as she prized open Twilight's mouth with her magic and withdrew her cock, intensely angry she screamed at her "Bitch!" then decided that violence was the best course of action. She whacked Twilight around the head with one hoof and the clattering sound of something on the stone floor alerted Twilight to the fact that the force of the hit she took had actually broken off her horn.

"My horn..." Twilight whimpered "My horn is-" Twilight didn't get to complete her lament as she received another hit that knocked out a tooth, then another that made her nose start to bleed and then another until Nightmare Moon decided she had roughed Twilight up enough, Twilight simply sobbed as blood dripped to the floor and tears ran from her bruised eye.

Nightmare Moon calmed down, she magically picked up Twilight's horn and decided to ram in into Twilight's rear, Twilight gasped and stood straight up, her face sweaty from the stress of the whole situation. Nightmare Moon said in an almost motherly tone "Listen here Twilight Sparkle, it may be hard for you to believe this but I don't actually want to hurt you no matter how much I enjoy it, I want your freedom and happiness but I can't give that to you unless you cooperate with me. All it will take for you to earn a year of almost anything you want is one ejaculation, don't make this harder than it needs to be OK?"

Twilight nodded, it would be slightly silly for her not to take that deal, even if she had to carry Nightmare Moon's child. "Good" said Nightmare Moon, she removed Twilight's horn from her butt, then using magic she fused her horn and tooth back in their rightful places whilst healing her broken nose and bruised eye, Twilight looked as right as rain. "See? I can be nice" said Nightmare, the pain in her cock had dissipated and so brought it back in front of Twilight's fate "Now, let's try this again, properly this time" said Nightmare.

Before beginning Twilight simply said "B-But I'm a virgin... I was saving myself for someone special..."

Nightmare Moon didn't have time for this and in an exasperated sigh went "Believe me Sparkle, I am currently the most special pony in Equestria and also the world, your virginity is soon to be a thing of the past, so please stop blathering on about things that are of little to no consequence and suck my cock!" Twilight obediently opened her mouth and allowed Nightmare Moon to slide her soft-but-not-for-long dick into the warm wet confines of her mouth. Nightmare Moon just hummed in satisfaction as she felt the hot and moist embrace of Twilight's mouth around her dick, she practically shuddered when Twilight began sucking, lightly bobbing her head back and forth "That's right..." said Nightmare Moon, part of the enjoyment wasn't just the forced blowjob, but the fact that Twilight was now so broken. Nightmare got a certain thrill that Twilight was not consenting to any of the sexual activity she was about to engage in with her but was sacrificing that choice anyway for the sake of freedom. It was cute in a pathetic sort of way.

Very soon, Nightmare removed herself from Twilight's mouth, she was hardening rapidly and knew Twilight wouldn't be able to hold the entirety of her erect cock in her mouth and throat... her pussy however... Nightmare moved around behind Twilight before hooking her forelegs onto Twilight's shoulders. Twilight closed her eyes and kept silent as tears continued to stream down her face, how had her life come to this? Right now she wasn't sure if the freedom was worth it, she questioned whether or not it would have been better to just simply lay down and die, starve herself to death, not allow the continuation of Nightmare Moon's bloodline. She'd become a martyr of some sort if she sacrificed her life in the hopes that Celestia would return and restore peace, but it was a long shot, she knew Nightmare Moon could find another powerful pony if she wanted to... even if took wasting much of her energy on a high level spell that would compel the most powerful pony in the world to arrive at the castle, such a spell did unfortunately exist.

Twilight no longer had time to ponder her situation as Nightmare Moon began pressing the head of her cock against Twilight's pussy, only to find she was having trouble penetrating. Nightmare hadn't anticipated that her spell might give her a cock too large to fit inside such a tight pussy, she knew it was possible that it might not fit but she had to try and repeatedly pushed more and more forcefully in an effort to enter Twilight's pussy. The strain of the attempts were making both of them uncomfortable, Nightmare was on the brink of giving up when finally Twilight's folds separated just enough for the head to squeeze inside, Twilight groaned at the mammoth stretching her pussy was undergoing and Nightmare grinned as she found that, although slowly and with a great amount of muscle power, her cock was slowly descending into Twilight's insides. The process of inserting herself inside Twilight proved to be a rather arduous task, she was barely one inch inside before she reached her first barrier, the hymen. Nightmare Moon took a short rest before again groaning as she heaved her hips forward, getting her dick inside Twilight was almost as tough as trying to fit a square peg in a round hole, the two just weren't meant to go together and trying to make it work was practically a stressful endeavor.

Nevertheless, Nightmare Moon persevered and the head of her cock burst through Twilight's hymen, claiming her virginity. Twilight did her best to remain quiet as she continued to allow tears to fall from her eyes and onto the ground beneath her, but she gasped when she felt Nightmare's Moon's cock press against her innermost barrier, her cervix. Nightmare Moon was initially disappointed, she only had half of her gargantuan member inside Twilight and she was struggling enough as it was... however, no better depository for her seed than directly into the womb, why should she quit here? Nightmare Moon tightened her grip on Twilight's shoulders and kept pushing, refusing to let something as trivial as the cervix stop her from getting the whole thing inside. Twilight as shocked and above all in tremendous pain, she couldn't believe that Nightmare Moon was actually trying to get through her cervix, getting inside her pussy had already been hard enough, was she really expecting this to work? She wanted to complain, but found the strength to stay silent, it was the best she could do in such a situation.

Nightmare Moon was becoming enraged and sexually frustrated. She leaned forward and roughly bit down on Twilight's left ear, drawing blood, in some attempt to gain more leverage, much to her surprise, it actually worked. With her hips pushing so hard and forelegs pulling Twilight back, the minute additional effort of pulling Twilight with her mouth was just enough for her dick yet again to enter a space that upon first glance was simply to small for such a thing, but there it was, Nightmare Moon's cock had now entered Twilight's womb. The squeezing Nightmare Moon felt around the head of cock was almost painful, Twilight's cervix was squeezing her like a vice. Again, Nightmare Moon had to take a rest before continuing before... oh for fuck's sake! Nightmare Moon was getting pissed off at just how difficult the simple act of raping someone was becoming, now the medial ring was giving her trouble, it was only slightly thicker than the rest of her dick and yet it still stuck outside and not entering the hole she was currently almost balls deep in.

Nightmare Moon didn't have time for this, she pulled back slightly and gave her first and hardest thrust, successfully jamming the medial ring inside, finally after some pushing she was as deep inside Twilight as she could get, her round heavy balls snuggled up against Twilight thighs and the base of her cock gone from vision, leaving only the sight of her hips pressed right up against Twilight's ass. Nightmare Moon released Twilight's ear shortly before healing it, then started to fuck her. Twilight groaned, there was a tiny presence of pleasure there, but it was vastly overshadowed by Twilight's physical and mental turmoil, her inside were abused and stretched, molding her in order to cope with something so large being inside her, her stomach actually bulged outwards obscenely with the distinct shape of a stallion cock almost threatening to burst through her torso if it went any further.
