A single big bright LED light lit the interior over every shadow. Tirek carefully trot inside sealing the door shut again. He brought his attention to the center of the massive cube revealing Luna, the formal Princess of the Night. She was suspended in the air; her body fully exposing her well endowed E cup worthy breasts and firm butt for Tirek's eye candy pleasure. She couldn't move too much either thanks to the strong enchanted steel chains keeping her firmly in place. She was tied with her legs spread in a 'T' form. Her arms above her head, tail out of the way and bound to the ceiling, and wings bound tightly against the other.

Luna glared, eyes radiating unadulterated hatred for the centaur. "Enjoying my humiliation, Tirek? Because this will be the last and only view you'll ever have of my bare body. You'll die a slow death for your sins." She seethed.

Tirek seem to almost enjoy the empty threats being tossed at him. He highly doubt she was going to go anywhere anytime soon. But gloating is not why I came to Tartarus to visit her.

He hummed to himself before trouting around the defiant mare. Without warning he slapped her ass firmly once. Her back arched at the amount of force and pain that erupt from the single slap. She also couldn't help a pained yell from escaping her lips.

"Let's make things clear enough for you to understand properly, you blue ass bitch. I get to decide if you live or die. But the only reason you're even still breathing is because you have some well overdue repenting on your past deeds against me. Otherwise, at this very second, you're nothing but a whining bitch in heat."

Luna's anger flared to even greater heights. How dare this nobody two-bit villain speak to her in such a degrading language and mocking her openly. She grit her teeth holding back the sting of the lingering pain to her ass. "Don't get cocky, bastard! I'm still a well known princess of Equestria. The Elements of Harmony will reign down a world of pain over you once and for all regardless of whatever outcome there may be. It's not like this farce matters anyway. You're just a upstart villain that just so happened to survive an already dying kingdom. The real truth is that you are nothing compared to your father, or brother. They both put up a better fight then you ever could in a eight thousand years. So you resort to stealing magic in order to even equate to rival anyone wor-"

The Princess' heart skipped a full beat feeling two giant hands painfully griping her smaller butt cheeks. Her train of thought interrupted by the sudden trickle of pain. Tirek used his thumbs to spread her butt cheeks exposing her vulnerable rear end. Immediately, her anger vanished a realization slowly creeping through her mind. Tirek's usual wild piercing yellow eyes turned a demonic red. His massive fourteen inch two and a half wide dick aiming down a target waiting to be destroyed. He didn't wait for her to get ready for the insertion; violently thrusting into her anal cavity. Luna's tight virgin asshole didn't even slow his mighty thrust, her ass cheeks slamming hard against his balls. Unimaginable amounts of pain racked her entire body. She didn't care how loud it was, all she could do was scream through the piercing pain.

Tirek kept his length buried forcefully deep inside of her. Her voice eventually turns into a meek moan before Tirek used his towering frame to lean over. He sees Luna's eyes almost half way rolled into her skull. Her eyes had a couple tears running down her cheeks. "I don't think I have to tell you where you fucked up, bitch. You'll get no mercy from me now. Prepare your anus."

That's all Tirek even wanted to say on the matter. Proceeding to violently thrust himself repeatedly into her. Her pained cries continued mercilessly being pile drived. She took the pain before bursting into tears.

"I'M SORRY! PLEASE SPARE MY ASS! I'LL NEVER MENTION HIM AGAIN! PLEASE. ANYTHING BUT MY ASS!" She blubbered on.

However, Tirek was not interested in any form of apologizes. He wanted her to know just how far her words hurt him. It wasn't until later on that her cries of pain started to shift to moans of actual pleasure. She wasn't sure why, but her body seem to be adapting to her predicament at an alarming rate. She also felt a growing desire between her spread legs. Tirek's fury grew not satisfied with this outcome.

He thrust violently twice inside of her momentarily bringing up a burst of pain again. "Oh now you're getting off of this?! Who knew how much of an ass slave you turned out to be! Looks like you should have spent more time fucking your rectum then bitching about a popularity contest! You must have been fucking yourself brainless with a moon pebble for a thousand years!" He picked back up again erratically thrusting his steel hard dick into her abused tailhole again. "While you squabbled and ended up trapped for a thousand years on the moon, I was stuck down in Tartarus for three thousand years! I watched my family slowly get corrupted into monsters before you two slaughter them where they stood! You think you know pain? This pain you feel is not even close to how much pain, suffering, and absolute rage, in its purest form, you and your bimbo bitch of a sister put me through!"

Luna seem to have a long gone expression while Tirek continued his onslaught. Her head slumped forward, but Tirek was not having any of that. He grabbed a hand full of galactic star hair strands forcing her head in a upward motion. He then slapped her ass hard a couple more times in the process. It got a couple more pained moans out of her. She felt her body warm up even hotter than before the pain increasing the sensation between her legs. Luna shook in the shackles and scream in odd ecstasy causing a steady stream of girl cum to spread across the floor. Her eyes rolled further into her skull before another ripped right out after another. Her orgasm didn't even seem to slow down until Tirek changed positions. His rod moving a steeper downwards slope into her ass with a strength comparable to a bucket of lit TNT. A moment later, he hosed her in seemingly continuous spurts of his cum directly into her large and small intestines.

Luna's brain must have fried in the heavy amounts of pleasure. Her mind and thoughts scrambled into nothing but wordless blubber, and useless attempts at communication.

Tirek eventually pulled out his mighty cock once his orgasm died off. He wordlessly watched the overflow of his cum drip down from her ass on the floor. Her ass seem to have a noticeable red tint mark to match as well. His eyes revert back to the normal piercing yellow gaze shortly after. He almost sneered down at the fallen princess' degraded state.

He looked back at her face noticing Luna had her brain temporarily checked out at the moment. The centaur let go of her hair seeing her return to a neutral position. Tirek didn't seem to care though. "That's just a taste of the torment of what I have planned for you, little cunt. Next time I come for your ass, all you would even want to think about is how big your ass can stretch!"

A weak whimper was the only response she could reply back. If nothing else, Tirek knows that she'll remember the error of her ways, and learn to respect and obey him whether she wants to or not. But he still had to properly give a fitting punishment. Even he knew this was only a temporarily solution. Tirek used his newly gained reality warping powers to create an enchanted oval vibrator. He then carefully place the device over her clitoris, firmly taping it directly on the fleshy button. Luna's body lightly twitched at the touch. He didn't activate the device until he was close to the exit hearing Luna's moans rise up once more.

"Have fun with this present of constant denial while I'm gone. Don't worry, I'll come to stop it... eventually." Tirek commented. Luna again blubbered in unintelligible words engulfed in ecstasy. With nothing else to say, Tirek left the cube prison before fast-traveling to the next location in Tartarus.

Author's Note

Yeah, not sure what kind of level of porn this is, but it's something. It's a bit of a quick sex chapter, but decent in my opinion. Anyway, you can probably guess where this is heading to if you read inbetween the lines.

Yeah, I gave Tirek more history following to his imprisonment in Tatarus. Why? Because the canon reason was kind of...... vague. And only stressed how much power he wanted. Some extra bits of lore never hurt anyone.

Next chapter.
