Punishment

Summary:

When Byleth reappears before the monstrous corpse after five years of absence, he does not seem like the professor Dimitri once knew well.

Notes:

Well this is fucked up. Skull fucking the fic. Honestly, this is terrible and I normally don't put out half-assed fics and out of character so I orphaned this.

(See the end of the work for more notes.)

Work Text:

Dimitri is not the only person who has changed in these five years, the professor has as well. No longer does he show an expression on his face or a tone other than flat to his voice. It is as though he has returned to being the Ashen Demon that Dimitri was disturbed by. It appears in the end they are both bloodstained monsters who revel in slaughter. The professor gazed vacantly as Dimitri gouged out both of General Randolph’s eyes and ate them one by one, delighting in the agony and fear that struck Randolph's bloodied visage. Nor did he stop him when the monster broke every bone in the general’s limbs. Now the insufferable wretch wallows in the dungeons of Garreg Mach, awaiting death to finally take him.  

Dimitri stands in the ruins of the once beautiful cathedral this late evening, another ruination caused by that woman, and speaks with the suffering dead. Their pleas become stronger by day, and each day their torment grows. In the midst of his promises to the dead, footfalls echo throughout the cathedral. He grips tightly the shaft of his lance and turns to face whoever it is. The professor stands behind the monster and holds a tray of food and a water skin. As it has been this past month, his expression is barren and inches on ominous. He holds out the tray of food and Dimitri hastily accepts it, dropping his lance in the process, not saying a single word and begins to scoff down the food with his bare hand. He quickly downs the water and drops both the tray and water skin on the marble tiles. He picks up his lance and turns his back to the professor. 

“How do you feel, Dimitri?” 

All he does in reply is grunt. 

“Feeling... heavy?” 

Dimitri ignores the professor, minutes pass and Dimitri begins to oddly feel heavy as Byleth questioned. It is as though his very strength is being drained and his mind is becoming numb. His body is wading through a bog and mind lost in a maze, he feels dizzy and collapses to one knee and leans on his lance. His breathing becomes labored and vision blurs. What is happening to him? Was it the meal or water? But why would Byleth do such a thing? 

“Good. The drug is finally starting to take effect.” Byleth’s voice sounds to be a world away. He hears muffled steps and see him come into view. He stops square in front of the monster and kneels to be eye level with Dimitri. “You’ve been causing me lots of trouble, Dimitri... Disobeying orders and doing as you please. That stops now. I’m in charge of this army, not you. I’m going to teach you... a lesson you won’t forget.” 

Dimitri peers up and he can see red rope in his gloved hands. He gives a testing pull on the strength of the rope, kicks away the silver lance, and begins to bind Dimitri’s arms and thighs together. The beast tries to resist but it is futile, all vigor has been sapped out of his body from the drug he was given. The professor is not gentle with the binding and tightens it as much as he can. Dimitri tries to summon up his Crest to break the bonds, but he feels weak, so very weak. What kind of punishment does Byleth intend to call upon him? Here on his knees in the cathedral bound in thick rope. The professor tucks his tunic into the side of his belt and unlaces his trousers. His flaccid cock is exposed and Dimitri now realizes where this is going. Again, he pushes himself to muster up the strength to overcome the drug he was fed and break free. Is this even the professor? Would the man he once loved do such a thing? Or perhaps why this is happening is because Dimitri is a monster that deserves every type of torment imaginable. He is a bloodstained beast that should have died long ago after all.  

“First I’ll make use of that mouth that growls so much at me.” 

Byleth presses his cock against Dimitri’s lips and forces them to part ways for him. The beast doesn’t move his tongue nor attempt to resist, he just lets it happen and hopes for it to be over soon. Back during his academy days Dimitri imagined many times of sucking on Byleth’s cock, but this is not how he wanted it to happen. The professor thrusts his cock inside Dimitri’s mouth and he gradually fills with life and becomes heavy on Dimitri’s tongue. Once he is fully erect, he withdraws his cock and roughly grabs the monster by his dirty locks.  

“Now it’s time for your punishment, Dima.” The nickname from his childhood scalds him. The professor takes off the black leather eyepatch concealing his empty eye socket and tosses it aside. He pries open the socket with two fingers as much as he can and lines his cock up with the scarred hole. It cannot be, he is going to fuck his eye socket? The very through of it sends worry and fear down his spine. Ah, but this is what someone like him deserves, is it not? 

‘Having your eye-pussy raped by the man you love is a light punishment for a monster like you.’ The tormented dead speak into his ears, startling clear over the white noise that is his subdued mind. They are right. 

Byleth inserts his cock into Dimitri’s skull, going as far back as he can and proding the sensitive flesh within. He removes his fingers from around Dimitri’s socket; the stretch aches and feeling of an invading object in his head sends his mind into a panic. The professor begins to move, slowly fucking the back of his eye socket and as he tugs onto Dimitri’s hair with both hands. He steadily increases speed and a searing pain can be felt flooding his eye socket. Before long, Byleth impales Dimitri’s nerves with a rapid and powerful velocity. It hurts terribly so, each pierce into his skull wracks his senses with agony. He feels warm liquid pool in his skull and knows it to be blood. Crimson must be seeping out of his eye socket as he feels it drip down his cheek. Byleth contiunes to rape his eye socket, pounding his dick as deep as it goes; Dimitri knows it must have breached his socket and enter his brain cavity, fucking his brain without a regard for the damage it will certainly leave. A few more pumps and Dimitri hears a moan and feels more warm liquid fill his destroyed eye socket and fucked brain; he knows that he has come inside him. A few more vigorous thrusts and the world goes black for Dimitri. He truly deserves this, the monster he has become must be punished even if it leaves lasting brain damage. As long as he can still fight he will do the one thing he must do: avenge the dead, even if it is the last thing he does.

Every wound and anguish is well deserved by the monster who should have died with everyone else in Duscur. 

Notes:

This was an unhinged experience. I wrote it in two hours while babysitting my toddler cousin with cocomelon playing in the background the entire time. Thank you for reading this mess I guess. I didn't even edit this.
