The unpleasant feeling suddenly turns into excruciating pain within seconds, and you fell limp but were being held up by magical shackles that were the same color as the demonic pentagram below your feet. The pain intensifies and you find yourself changing while and you were screamed blood curdling screams. Your body was growing and you're muscles were bulging and growing more and more, and your entire body was enlarging. Your feet morphed into giant hooves, and your finger changed into large 2 foot claws. Your face pushed out slightly into a cow-like muzzle but your teeth sharpened into carnivorous teeth capable of tearing apart only meat, and your tongue became forked. You grew two horns out of the sides of your head which curved forward to act like horns that could charge and impale your enemies.
Your voice changed to sound deeper and your screams turned into roars. Your hair then fell out and your skin took a tone of red as your body continued to grow more muscular. You then grew a tail similar to a bull with a small tuft of red fur, or hair on the end. Moments after that two giant wings that resembled that of a bat or dragon grew out of your shoulder stretching a little bit under twice your body length. Your attention now was on your dick as it suddenly grew to about 5 feet long with the width of baseball, and your balls enlarged to the size of basketballs. However, despite the size of your dick you were now well over 20 feet tall, and your muscles bulged and your dick throbbed and you moaned and you saw your dick produce a small drop of glowing orange and red liquid like magma. You felt new instincts take to your mind like thoughts that you wanted to carry out, thoughts to kill humans for blood and feast on them, thoughts to prove your dominance and overtake a lesser demon like an imp or succubus. Your body now looked like a giant hulking minitaur with claws and wings who had the strength of over 200 men, and had a dick to shame all who crossed it.
You shook your head though and tried to get back to focus, and looked to the warlock and growled,"You...what did you do to me!"
"I turned you into a behemoth of a demon so you can be made useful to me as my familiar. I know you want to kill me in the most violent way possible for revenge, but in your case that is no longer an option." The warlock said
"And why not? I can snap you like a twig, and I'll feast on your bones...ARRGH!!! No, no more of these god damned urges to kill!" You roared trying to get a hold of your humanity.
"Because if I die then so will you thanks to the laws of you becoming my familiar, but you can roam free after I expire naturally. But I know a demon like yourself can be pushed to the point to not care about such things. Your loss of intelligence is also a consideration, so I'll give you a proposal. Willingly assist me and you will earn rewards in the form of meat, blood, and anything your instincts yearn for. However, if you oppose me I will lock you in my dungeon and use you only to kill and torture my enemies." The warlock said
"I...I can't decide, one half says one thing but the other half says another. But, I don't want to kill...but I want to kill! Arrgh!!!" You roared again
"Why do you hold on to your humanity? Let it go and let your new demonic self take over, it's going to happen eventually, I'm just giving you a less strenuous and painless solution. It's simple just close your eyes and let your instincts take hold of your mind, but don't let those instincts take it completely, but use them as a guide." The warlock said
"I...I.....I...." you say, and you felt your demonic instincts seeping into your mind and corrupting your senses, but you could still think and you let them guide you as the warlock said.
"I do not wish to die, I wish to live and taste this new experience like I will the blood of those who wish the downfall of you, Master." You said giving into the urges, but not completely.
"Good, now a demon like you needs a name, like Beleth after a fictional demon king." The warlock said
"I like that name very much Master, but what is yours?" You asked
"Wrane, but you shall call me Master Wrane, or Master, understood Beleth?" The warlock, Wrane asked
"Understood Master Wrane, now may I ask you to release me of my shackles and serve you more freely?" You asked
"Why yes, of course you're not much use all chained up now are you?" Wrane said rhetorically, and your shackles disappeared with the pentagram, and you bowed to Wrane.
"What are my orders Master?" You asked
"Follow me to my home, and from then you will guard the exterior of it. Kill anyone you wish, and dominate anyone you wish with." Wrane said
"What do you imply by "dominate" master?" You asked
"Why, putting that new member and seed of yours to use. A very enjoyable part of being a demon is that anyone who takes in your seed becomes a demon as well, and a demon to your desire and well fitted too." Wrane said, and you felt your member slowly becoming erect as the thoughts of what you could do with your new dick.
"Now come, your duty awaits Beleth and I can see you're eager to begin." Wrane said gesturing for you to follow, and you did and each of your steps made a large thumping sound and left a hoof mark in the ground with each step.
Wrane lead you to an abandoned castle in the center of an abandoned town, and everything around you looked destroyed except for the castle which was in a state of depreciation. "Here we are, now do what you will, but don't forget your duty here. Eat, fuck, and make waste anywhere, but not in a way that is annoying or interfering. You are to never enter the castle unless given permission by me personally, and under no circumstances. " Wrane ordered, and you nodded obediently.
"I will allow no entry for anyone, or anything except for you Master Wrane." You said, and Wrane nodded back and walked inside. You then walked around the castle and patrolled the area around it to get a feel for the surroundings. You continued your patrol until you picked up a scent of something with your new enhanced nose, and it smelled like blood, human blood so you rushed over and saw eight humans in a group with both male and female humans. Then you...
