The only hope of the empire was a single person. It was the third prince of the empire, a brilliant and intelligent boy who was as beautiful as he was smart. Countless victories against the demons were made by his careful guidance. His quick and adaptable thinking along with his great charisma and charm made him the empire's best commander. No doubt if he had wanted the throne he would’ve already had it.
However.
The demon lord had understood this fact. So, what would happen to the glorious empire if their only asset was gone?
Well, it would collapse of course!

He opened his eyes to a room and a person looking over him. No. Not a person. This was the demon king.
“You’re awake, I was about to start with you unconscious~” he said, a smirk on his ghastly face.
“What did you do! What is this place!” Evian yelled at him trying to get off the bed only to see his hands chained to the bed. Further than that he found his clothes, “w-what is this?” He asked no one. He was dressed like a prostitute. Sheer white silk. Piercings on his body at places he didn’t remember. A large collar around his neck.
“Now. Why don’t we get to it, dear prince Evian.”
“No. Don’t come any closer! Don’t touch me!” He tried to struggle and scream but it was all useless as the demon lord placed a hand over the prince’s stomach. Soon a seal appeared. It was a lust seal, one that would ensure the prince act like a lewd, horny bitch in heat.
——————
“Ah! Oh~ n-no~ ♡! It’s mmmmh~” Evian moaned uncontrollably as the feeling in his stomach just got hotter and hotter, “aah!”
“That’s right! Moan like the slut you are! If you’re the one coming up with all the strategies I’ll just have to fuck them out of you!”
“Oh!~ ♡” Evian climaxed, his eyes rolling back with his mouth opened in an O lewdly. Even after he came, the demon king had no intention of stopping, he continued to fuck the prince over and over through multiple orgasms.
“Come on! Tell me how you feel, slut! Scream it out!”
“S~So good~! Ahn~♡” his brain was so foggy, what was going on? His brain was short circuiting from the pleasure.
“Who knew the famed third prince really was just a slutty bitch begging for cock!”
“Mhmm~ c-cock I- mhmm~♡”
“Yeah. I’ll breed you! Breed you until all you can think of is my cock in your slutty pussy!”
And he did. For days and weeks he bred the prince, the only sustenance he got was the cum from the king. He kept breeding and breeding until all the prince could think of was the large, girthy, darkly colored cock from the demon.
The king truly did breed the prince. In just 2 weeks the boy had gone from being flat chested to having B cups to C cups to DD’s, and they showed no sign of stopping. Even his reproductive organs had changed. He used to have a sizable dick but now. Now. Under there was a burning hot pussy that dripped and gushed with juices at the mere mention of dick. Even with his fat pussy, the king still found that it wasn’t enough. So. He started injecting in hormones and potions even pumping it to make sure that no matter what under wear or pants the prince wore, his fat juicy pussy lips would still be seen as distinctly as if he weren’t wearing anything at all. His hips had grown so wide and motherly and his ass had grown into a sizable bubble butt. Now, all he could think of was dick in his pussy. His fat steaming dripping pussy.
The demon king even made it so his two huge yet still growing breast would be penatratable. The demon king would penetrate his tits and fuck them as if they were nothing but two pussys. As he stayed at the castle his assets and mind only grew more corrupt. His breast soon grew to E then F and soon he had huge H cup breasts. His waist however still remained a thin thing, even more thin. The lips on his face had also grown to be thick and glossy much like the lips downward. He spoke with a lisp whenever he wasn’t moaning and pleading for more dick.
“Pweees swaap my bwitch tits!” He cried as the demon king rammed his dick into the gaping ruined hole that was the prince's pussy. His huge tits had dark nipples that seemed ready to burst with milk. His pussy jiggled with every movement and his large bitch tits bounced erratically. He came like a bitch once the king began to slap his tits as he rammed into the bitchs womb. His mouth was open in an O and he kept moaning and moaning.
“How about I give you an upgrade?” The demon king laughed before holding his hand down on the princes abdomen right at where the mark of lust was and pressed. Soon, the prince began to change once again. His tits began to swell once again, he moaned at ever size they went up. As his tits grew, so did his dark nipple and areoles. Each was now the size of a plum. His ass grew once again and so did his hips, they now truly looked like childbearing hips. His pussy lips got even thicker and larger however his holes stayed virgin tight. Now, they jiggled at the slightest movement. He looked like a horny succubus now, the queen of them.
“I originally wanted to use your brain to plan and kill the humans after breaking your spirit however, I think you’d suit better as my Queen than as a simple brain to use. And…” the demon king looked down at the ex-prince with a smirk and lust filled wild eyes, “I doubt your brain would be of much use now, not to mention your body.”
On the bed was now a person who could in no way be even remotely called a man. No. The person on the bed was a lewd, horny, bitch. The Demons had won. The only thing the humans had over them was now on his knees worshiping the demon king. The humans had lost a prince while the demons gained a Queen.
