I'm really cryptic with my titles. Like, what's this story about?

A human thinks he can manipulate Twilight into having sex the way he wants, but instead ends up biting off more than he can chew.

Pegging ensues

Why did I write this?

For the time that I’ve been in Equestria, my need for kinky sex has increased tenfold. I believe it to be the result of me being with my marefriend, Twilight. Our love of experimentation is practiced not only in the form of Equestrian science, but in the bedroom as well. Although, we also fucked in the bathroom, living room, public, etc…

Recently, I’ve gotten a little bored with the usual shit we do when we fuck. It’s pretty much just me being a sub for Twilight, and her telling me what to do. There’s rules I’m not supposed break, or I’ll be punished. However, I’ve never broken a rule, and I don’t even know if Twilight is a push over and just saying things in character, or if she’ll actually do something if I do misbehave. So I’d say it’s time to test her. I’m going to be a little shit and she’ll have to punish me.

Twilight had just gotten her new chemistry set in the mail from the United Pony Postal Services so most of the morning had been the fizzing and popping of chemicals in the library’s main room. There was petroleum in her beakers which was being experimented on. I had been telling her about automobiles back from where I used to live on Earth, and the mention of engineering and technology really gets a pony like Twilight going. She does need to know every detail about everything.

So here I was, on the library’s couch waiting for Twilight to make an Equestrian advancement in science, and I couldn’t care less about anything except the sex that was scheduled for tonight. I was hoping she’d be done soon, because the dirty thoughts about her punishing me like her bitch were getting me all flustered. And wouldn’t you know it, just as I was thinking my selfish thoughts, a crackling explosion left her face covered in black soot which seemed like enough to get her to stop and wash up a little.

“Gah!” she coughed out.

“Geeze Twi,” I said, although I really was more concerned about getting an excuse to carry on through our schedule for the day, “I think we need to get you cleaned.”

I shut the bathroom door behind me while wielding our towels. It’s pretty much expected of me, being human, to clean both of us off with my hands so I regularly share shower time with Twilight. Twilight though, was currently in under the water already. I saw her there, as she was being drenched, and my mind was thrust into the thoughts of how taboo seeing another human naked in the shower was. That made me pay attention to my mare’s body.

She was enough to turn any prude into a horse fucker on the spot. Her hips were curvy, body was voluptuous, bangs were the perfect style to compliment her geekiness…

“John?”

“Huh,” I responded. Twilight had broken my spaced out ogling.

“Are you coming in?”

I made my way in, and I began the lathering of her body. It was easy to tease her with my human hands. I started to massage her back and made my way up to her neck where I gave her a nice kiss and nibbling. She grunted in approval at the sensation, and started cooing when my hand retreated back to her flanks. Her wide, fertile hips were so squeezable and luscious in my grip.

Now I was getting to be the conniving bastard I am. If I’m to tease her just right, where she’s ready to fuck me to death once we get to her bedroom, and I refuse, she’ll have no choice but to punish me in her desperation. My lathering hands were now exploring her backside to fuel the fire for my punishment. I was only inches away from her marehood, and my index finger came awfully close to her pussy lips. She winked in response. Viscous fluid of her arousal came out with her winking in a thin transparent strand that stood out from the flowing water due to its slow cascade.

“Bucking stop teasing me,” she warned as I laughed out loud to her complaint. She huffed in annoyance at my amusement. It was all going to plan so far...

The time had finally come. Twilight and I were no longer damp from the shower we’d taken, and I was sprawled out on my back on her bed. She came up to the side of her bed that I was on while my hands were resting my head. Twilight was wearing an evil smile that told she had something up her sleeve.

“Alright Human, you know the drill,”

I undressed while still laying down at the sound of my sub name being called out which signified it was time to be in character. Next, Twilight raised herself above me with two hooves on either side of my perimeter. Being underneath her made me remember that she wasn’t small and about my weight. I swallowed hard from nervousness at how she could punish me physically.

“All that teasing you did has me bothered”

Twilight was talking while looking below herself to my waist. Most likely to gauge if I was hard or not. Currently I wasn’t, but how could I be since this wasn’t even the freaky part yet, right? Her hoof came down to my crotch to try and stroke me. I wasn’t having it though. I squirmed at her touch like a annoying child.

“Either you let me warm you up, or else...”

“Fuck you, horn head!” was my breedist interjection. Twilight’s face went blank with registering what just happened. I just touched so many nerves and broke so many bedroom rules by saying an anti-unicorn slur and disobeying her. I turned my head to the side in disrespect, ignoring her. I couldn’t help but start to start to chuckle at my outburst that shocked her. It so funny when someone as smart as Twilight gets dumbfounded. Twilight gave one of her signature growls she does when she’s frustrated and spoke.

“I’m giving you one more chance, Human,” was what Twilight gave as her final warning to me. An idea came to me for really setting her off as she was giving me a dead serious stare. Equestria was a matriarchy so insulting somepony’s father by saying that you were fucking him like a slut was pretty much the perfect role reversal insult to give.

To my self induced horror, I gave my last ignorant statement, “Nightlight sure didn’t refuse when I fucked him in the ass!” Twilight had definitely had enough of my shit. A magic bind came down on each of my limbs, totally holding me captive.

“I’ve been planning for this you little bitch,” Twilight informed me. Her gaze into my eyes was domineering and frightful. She put a blindfold from her nightstand on my eyes. So I wasn’t the only one with a plan for this type of thing.

Mistress Twilight had left me still blind to where she had levitated me after I provoked her. Where ever I now was had a hard, concrete floor, and there was now a heavy metal chain around my neck which I felt with my hands to be magically connected to the wall. I couldn’t get more than a few feet walking around the room with my restraint stopping me. I had no vision, no mobility, and Twilight left me in the room by myself for the past hour. She said she needed to get a few things for her plan, and that I had to have time to think. Really, am I fucking six?

My ass was planted on the concrete floor Indian style while waiting for Twilight. To my fear and excitement, a door opened and the familiar creaking of a staircase was going on in front of me. Twilight had entered the room, and she audibly approached me.

The blindfold on my face was removed to give me a full view of my surroundings. I must have been in the basement of the library as it was dimly lit, had an acid stained concrete floor, and unpainted blocks made up the wall. It was more akin to a dungeon than what you’d think a library would have as it’s lower level. In what I was guessing to be a way to enhance what she would consider to be a sinister mood, Twilight had turned on a stereo that was placed in the corner, and It was playing some type of death metal.

“Naughty, naughty,” she tisked once she spoke, “you should take a deep breath.” What? Twilight’s horn lit up, and her magic grabbed my chain. It forced me to the ground where it pulled me down till I was laying on my back on the floor. I was still trying to get my bearings when Twilight stood above me like she had earlier, except this time she was backward with her rear end above my face.

“You get to breath when I think you’ve earned it.”

I looked at her snatch that was right above my face with the ceiling in the background, and she currently had a drip of her arousal in the middle of its fall to my chin.

“I was hoofing myself before I came in so I might be a little wet.”

Her ass came down onto my face just after I got a good breath. I was smothered under her crotch. My mouth was buried in her entrance and my nose was covered by the the area between her pussy and ponut. Her hips began to gyrate on my face while she had most of her body weight on my head.

“You should be licking!”

Twilight gave me a hit to my ribs with her hoof to show she meant business. So I began to, but as I did, Twilight started to go faster. I just extended my tongue as far outwards as it would go and let her grinding marehood do the rest of the work in pleasing her. I couldn’t last much longer though. I had to have held my breath for close to a minute.

“Alright, good boy. You can breath.”

She lifted off from my face for me to breath. As soon as she went up she came back down not giving me much of a chance.

“I’m not grinding so no cheating this time.”

My tongue went into overdrive now since she wasn’t going to grind. Trying to stimulate her tunnel as much as I could, my tongue lapped at every bit of juice emanating from her. My efforts were rewarded with more of her winking and moans. She let me get one more breath before she came down a final time.

“Buck, I’m close!”

Her walls were trying to clamp down and flexed, dispelling more fluid onto my awaiting palate. Twilight's legs started to spasm and her back arched. She screamed at her orgasm that dumped a good amount of mare cum onto my entire face. She collapsed on top of me with her marehood still in contact with my lips. I gave her a final smooch which prompted a moan.

We’ll start a new position. I’m getting bored watching you squirm.”

Twilight’s magic was once again pulling on the chain I was wearing for me to go up against the wall. I sat against it with Twilight now approaching me. She sandwich me between the wall at my back and with herself. Twilight straddled my hips while my erection came to be between her and my abdomen.

“Back to where we were earlier.”

Before aiming my dick into her, she used her magic to bind my hands under my back in the small space made with the slouched position I was in. I was completely powerless protest as her hoof grabbed my member and pointed it toward her marehood. She went down with her lower body and enveloped me into her tunnel. She was so hot inside, and it contrasted to the coolness of the lower level of the library.

I was caught up in the feeling of myself inside of her. It was pure intensity. Twilight was slamming herself up and down with ferocity, and my pelvis was starting to feel hammered.

“Naughty human.”

Twilight struck me in the side again and left a red spot to become a bruise later.

“Who owns who, bitch?”

That line was followed by several hits to my chest and arms. Goddamn, I was going to have to wear a shirt, or I’d look like I got in a street rumble. Another thing bringing me pain were Twilight’s teeth that had been biting on my neck and ears while she was fucking me. All this was making a familiar pressure build up inside me. I was close to cumming.

“Mistress, I’m about too…” I warned about my orgasm.

“No”

Twilight brought her hips entirely down to hilt herself on my dick. I was rocked with intense pressure in my dick. I couldn’t cum. I noticed Twilight’s horn was glowing and my cock had a tingly magic feeling to it while it was entirely enveloped in her warmth.

“Good boy, but I don’t think you learned who’s boss around here yet.”

Twilight made her way up the length of my cock and dismounted. She walked to the bag that she must have brought in once she entered. She shuffled around looking for something until she brought out a large dark object. Once my eyes focused in, I could make out what it was. It was a huge horsecock strapon that had to be three feet long! I was now in total panic mode at my realization. There’s no way that thing’s fitting in me!

“Twilight! No, please don’t mmmmfff!” was what I got out before she put a rag in my mouth shutting me up. Her magic levitated into a position much easier to penetrate with my ass up and head down as she adjusted the belt around her waist for the megacock.

“This should learn you!”

She mounted me and first contact of the tip with my ass was made. She started to put force into a thrust forward but that thing was just too big to fit. It was like trying to stick your dick in a Cheerio. I heard her grunt in frustration at her futile attempts to stick it in me. Maybe Celestia was looking down upon me and giving me some mercy.

“Shit, I guess I gotta use Plan B.”

As she left her position on me I turned to see her applying some horn wax from the bag to the dildo. Then she took a stance like she was ready to charge at me.

“I’m gonna fuck you in the ass!”

Twilight screamed her battle cry before charging at full speed. Well that was pretty blunt, but I digress. She hit my anus with the dildo spearing me like a shish kabob. I screamed to the ceiling at the insane pressure in my asshole. It was too much to take. I felt like passing out with so much pain and shock. When I looked backward at my penetrator, I could see that she was desperately trying to pull back.

“Umm… I think it’s stuck…”

Are you fucking serious right now? Now I actually was passing out with that good news being told to me. Everything went black.

I woke up in what had to be the Ponyville hospital. Once I turned to the right of my bed I was laying in I could see the caramel colored doctor and Twilight looking at me worriedly.

“Son, you’re lucky to be alive,” the doctor informed me, “you went unconscious from a 3rd degree collapsed ass.” Well that’s just dandy.

“Oh, John. I’m so sorry. I didn’t know you were going to get hurt! Doctor, can he at least walk around?”

“Yes, but be careful now. The surgery was success, but you’ll still need to take it slow,” he warned me. I rolled my eyes and attempted to get up before looking to the doctor for approval. It was so strange though. My lower body was totally numb from the surgery on my ass.

I got my bearings, but there was a loud thump once I reached a straight stance. I noticed the doctor and Twilight looking down at the ground in shocked horror. When I looked to what fell from between my legs I saw a familiar black, three foot strapon. “Oops, we forgot to take that out,” the doctor told me while cringing.

What the fuck.
