...And something else, too.

Fluttershy nervously shuffled her hooves, staring at the libraries' door with an ever-growing sense of doom. She never thought that she could come up with so many different ways for one simple conversation to go wrong in just ten minutes, but, well, here she was. And she had at least 75 ways so far.

The rest of the day had went surprisingly well. It was about ten months into their relationship, and she had just told Big Mac her deepest, darkest secret - Her masochism and gore kink. Not only was he totally accepting of it but he even agreed to try it, given that they had a safe way.

And, as fate would have it, Twilight showed up later that day with amazing news...

Fluttershy was brought out of her thoughts by the door opening in front of her face. Twilight stood there, staring at her yellow friend quizzically. "Fluttershy, You've been standing out there for eleven minutes now. Is there something that you need?" Fluttershy let out a small squeak and ducked her head. Oh Celestia, how was she going to tell Twilight about this?

"Uhmmmm...." Fluttershy started, biting her lip. Best get it out quick. "I want that new spell you found!" She whisper-yelled, quickly but quietly. Twilight looked confused.

"The anit-wound immortality spell? Fluttershy, what in the world could you want that for? I mean, sure, I can cast the spell on you, but whatever for?" Twilight asked, cocking her head to the side.

This is it. Her mind racing for an excuse, Fluttershy sucked in a breath. when she opened her mouth to speak, what came out was not an excuse, but rather - "SoThatICanHaveKinkySexWithBigMacintosh!" It was a quiet screech, and she immediately hid behind her mane in embarrassment. Wow. She actually said it out loud.

Twilight stared at her blankly for a moment, trying to understand the sentence. "So that you can have...kinky sex with...Big Macintosh...?" Fluttershy quickly nodded.

Twilight let out a quiet sigh. It wouldn't be the first time her friends had come to her for sex spells, and she was sure that it wouldn't be the last. She hated to think what Rainbow Dash had done with the futa and the enlargement spells..."Yeah, Fluttershy, I can cast the spell. And I won't ask what you're going to do with it, either. Come inside."

Thirty minutes later, Fluttershy was on her way home again. She was grateful for Twilight's acceptance, and left with promises of staying safe. Her foreleg tingled where their test-cut had been placed.

The spell was pretty simple - an enchantment placed on a rune-encrusted necklace, a talisman of sorts, so that the wearer could not be killed by wounds while wearing it. All wounds would be healed when it was taken off.

She licked her lips, opting to fly home to lessen the time of her trip.

She was home in a record time, but stopped and hesitated in front of the door. She had never thought to ask Big Mac whether or not he was REALLY comfortable with this. Sure, he had agreed to it, but...What if he was just doing it for her? She didn't want to be a bother.

Slowly, Fluttershy eased the door open. All the animals were out of the house, as she had requested of Big Mac when she left, and she found the large red farm pony on their bed, aimlessly flipping though a magazine. He looked up when she came in, and smiled at her.

"Worked?" Big Mac asked her, tilting his head to one side.

Fluttershy nodded, walking over and climbing into the bed next to him. "Mac, I just wanted to let you know that, mmmh, you don 't have to this. If you, uhh, don't want to." She stared down off the bed, her blushing cheeks hidden behind her mane.

"Ah know that." Big Mac said softly, leaning over and nuzzling her neck. "But ah want to make you happy, Flutters. And don't you think that it's only for you, either."

Fluttershy looked up at him and smiled. "You always know what to say, Mac." She gave him a quick kiss, then stood up and hopped off the bed. She was newly invigorated to try out her fetish.

It took but a few minutes to collect their supplies - a condom, a small kitchen knife, a large horn file, a small hammer, and a serrated spoon. Fluttershy laid them out carefully, next to where Big Macintosh sat on the floor. She sat down in front of him and took a deep breath, steadying herself. He was already half hard, so he quickly began to react when she placed her mouth on his cock-head, licking and sucking around the rim.

Fluttershy slid her mouth slowly down his shaft, swallowing four times in quick succession once she reached the half-way ring. Big Mac let out a low groan, placing a hoof on the back of her head. He didn't push her down farther - she was about at her limit anyway - instead letting his hoof rest there. Fluttershy groaned softly around his dick, before pulling back for air.

She repeated this process several times before she stopped, and put the condom on. She gave the head a small kiss, before turning around and picking up the serrated spoon. She gave it to Big Mac, Who took it with a reassuring smile.

"Just, umm, put it in my right eye, like we talked about. I'll probably make a lot of noise, but remember that 'red' means stop, okay...?" Fluttershy said, earning another nod.

The spoon was slowly brought up to her face, and then she felt the cold metal touch her right eyelid. She shuddered.

And then it slid under her eye, and half of her world went red. "Ahhhughhhuhhhhh..." Her moan was long, and drawn out. Blood poured in a slow stream down her face, her pale fur turning red. Deeper in the razor-sharp spoon sunk, until it hit bone. Mac paused for a moment.

Gibberish spilled from Fluttershy's mouth, distorted even further by the blood that began to pool there. Her nether regions tingled and sparked with pleasure at the intense, painful feeling in her face. "G-g-green." Fluttershy moaned out, only hoping that it was understandable.

Big Macintosh, for his part, was oddly confused as to how turned on he was by this. He did not include himself sadistic by any means, but there was the most beautiful mare he had ever met moaning in front of him, seemingly in more pleasure than he had ever seen her before. So, with a slight nod, he continued and angled the spoon upwards, using a light sawing motion to cut through the optical nerve.

Fluttershy was in total bliss as the whole right side of her world went dark. Blood poured from the damaged socket, a seemingly endless river - and it was endless, really, due to the talisman that she wore.

With a loud squelching sound, the eye popped free and landed on the ground. Both Fluttershy and Big Mac stared in wonder at the teal orb between them. They both let out a small groan.

Big Mac set down the spoon gently, Hesitating for only a brief moment before gripping the handle of the hammer between his teeth. Fluttershy groaned and closed her good eye as he approached, struggling to keep her forelegs from giving out.

She waited anxiously for a moment.

With a loud crack, and startling precision, the hammer hit the direct middle of her eye socket. The bone there broke away, revealing the pinkish grey brain matter within. Fluttershy screamed, the white hot pain of her bone breaking causing her to orgasm on the spot. She slumped over, falling face-first on the floor. She twitched, large convulsions racking her body like electricity and screaming groans escaped from her mouth. She had almost expected it to start feeling horrible when they got to this point, but this...

Sweet Celestia, this was heaven.

Big Mac waited patiently for a moment, before grabbing the file and walking up to his pale yellow lover. He placed the file into her eye socket and started to rub it back and forth over the edge of the bone, removing the jagged sharp spots.

Fluttershy quietly moaned as he worked, only half conscious. That might be from the pleasure, or the fact that the file was repeatedly running holes into her brain. Either way, it felt amazing.

Big Macintosh tossed the file away , gazing down at Fluttershy with a nervous excitement. "Ummm...Ready?" He asked. She nodded slowly.

Fluttershy shuffled hr legs so that she was in a good position, and Big Mac stepped forward so that he was above her. Not for the first time, he was grateful for being so tall. Fluttershy leaned up and licked along his shaft, making sure that he was good and ready. She knew that she was. She suckled on the head, hearing him groan above her. Then she took a deep, shaking breath, and reached her hooves up to position him at her eye. She hesitated a moment, before giving him his confirmation.

"...Gr-Green."

Big Mac lurched forward, groaning as his cock pressed into her eyesocket, then through the hole in the back. "Ahh! Flutters!" He pulled back and humped back forward, feeling her move beneath him a little. She voiced pleasure loudly - or, at least, loudly for her - and gripped onto him.

"More...Please, more!" She groaned out, her hooves falling off of his hips, and Big Mac certainly didn't mind complying. He quickly picked up a rhythm of slow but hard thrusts, the room filled with their groans and the slurping, splashing sound of her blood.

Fluttershy, for her part, was masturbating furiously. This was everything she'd been hoping for.

Her thought got fuzzier the longer Big Mac went at it, partially from her arousal and partially from the fact that her brain was being slowly but surely pulverized. The thought made her squirt a bit. She rubbed her hoof against herself hard, her juices leaking out onto the floor.

It was over fairly quickly for the both of them. The buildup had been fairly intense. Big Macintosh picked up his speed as his pleasure heightened, then all of a sudden his hips stuttered to a stop. He let out a low groan, flooding his cum into Fluttershy's skull.

She stiffened as she felt it - the thick white liquid pouring in alongside her crushed brain matter.She let out one long, ragged breath and came the hardest she ever had, blacking out for a few seconds.

She slowly came back too as she felt her lover's softening cock slowly pulling out of her face. She shuddered softly, her already weak knee's giving out now that she wasn't being partially held up by something else. She fell forward, her face landing in a damp puddle of pale pink, with darker red spots in it. More of the bloodied cum leaked out of her face, splashing wetly into the already large puddle. She debated licking it momentarily, but didn't have the energy to open her mouth.

She felt a warm breath on her neck, and then Mac slowly pulled the talisman off. He hesitated for just a second, then gently picked up her face to slide it out from under. She felt a sudden and intense tightness in her chest, Then her eye forced itself closed.

And then she felt perfectly fine. Still tired, yes, but now she could think straight and, upon opening it, her eye worked just fine.She smiled up at Big Mac in a lazy way. "Thank you so much..." She murmured, blinking slowly.

Big Mac smiled back down at her, setting the talisman aside before laying down next to the cream mare. He nuzzled her neck, smiling all the while. "You're welcome, precious."

Fluttershy smiled, pressing herself against him. She loved it when he called her 'precious'. She'd have time to wake up and be ashamed of the mess later - for now, she wanted to sleep with the love of her life.

And if she let out a noise of excitement when later, with a hint of disgust in her voice, Twilight said that Fluttershy could keep the talisman - well, who could blame her.
