A story that's in my head for a long time ago, first come the picture (I edited it myself), then long after here comes the story.
The model is Dejan Stipke Stipić (Too bad he shaved his head.)
"Aw!" Toby groaned as something fell onto his head. He looks down to see what it is. The object is some kind of sexy gold metallic glove with a couple of colorful jewelry embedded. Toby looked around, there couldn't be any possible way for it to fall down onto him. Everywhere on top of him is an open sky. He picked the gauntlet up and slid it into his hand. At first, it seems to be too big for his hand, but it shrinks to fit his hand perfectly.
"That is not yours to play with, boy" Toby jumped as he turned around only for him to jump in shock a second time as it revealed that the owner of the booming voice was a bizarre purple giant.
Thanos wastes no time with this meaningless meek creature and forcefully snatches it from Toby. He has a war to fight some lucky enemy have managed to snatch his gauntlet and drop it onto some random dimension. He needs to go back and finish his mission. "Stop!" Toby yelled in panic. The stones glow as Thanos' hand imminently freezes before he can touch the gauntlet. "What?" Toby breathed in a mix of relief and surprise. But he put the piece together quickly after seeing the stone glows and the purple giant froze in place.
"Woah, that's crazy. What else can you do with it?" The stone glows and bestows him with all the knowledge of the gauntlet and the stones. Toby's eyes widened in surprise and then his mouth curved into a malicious grin. "Hmm, really?" Toby's dissatisfaction with life and the world around him turns into something more sinister. He looks up at the purple giant, and for the first time, Thanos returns Tony's gaze with his own full of fear and despair.
"Let's start with you then. I think I will need someone to help me with what I have planned." With that Toby turns his palm to Thanos. The stone glows as he works on transforming the purple giant. His purple skin begins to fade into a more human-like color, along with his other features. Humanly hair begins to grow on his head, eyebrows, beard, and all over his body. Thanos can feel the change spread throughout his body, but powerless to stop it. He can't tell which is more terrifying. His skull cracks, rearranging his facial features into the shape of Toby's desire. A conglomeration of features of attractive men that Toby has pleasure himself to, the stone learned its master taste and made its adjustment accordingly, only leaving Thanos' distinct ridges as evidence of who he was.
Along with his body, his mind, and memory too, begin to change. Gone by his traumatic childhood that led him into his life purpose begins to fade away. Replaced with the new memory of being bred and raised to serve his master. Hours of brutal physical training that build his power and skill still match his old one, but instead of the training house on Titan, it's now a slave stable of his master on Earth. Another kind of training that his new reality has received is the mental one, hours of equally brutal brainwashing sessions strapped onto the gurney of the slave barrack. This Thanos has known nothing but absolute obedience and loyalty to his only god master. His mind was rewired and his neurons restructured and engineered into a perfect killing machine for his master, with no hesitation, resistance, independent thought, and doubt in his loyalty to his god master. He has always been his master's slave, existed, and was created solely to serve and be used in any way his master wishes.
The memory of his acceptance into full slavehood is locked into his mind along with the collar that appears around his neck. He remembered, the day he had first been collared and wearing it proudly since.
The rank etched into the metal of his collar and the flesh of both his skin and folds of his brain. The memory of being given the first of his rank tattoo as an enforcer for this master's will. Every memory of battlefields that the old Thanos used to exercise his own cause, gets altered into the place the master exercised his will through him, his most powerful weapon.
With each battle won he rises through the rank with each bar representing how deep his obedience has solidified, how it conquered and destroyed his independent thought and his body's reaction. For a normal being with free will, the technique is designed to inflict pain which would be deadly, but he has trained to master his own free will in surrender to obey his master's demand and order. He's only a tool for his master to use, the only reaction his body should have is to obey. Now the rank mark on his skin, collar, and mind represents him as a master's honor guard.
The master forced his new slave into all four and dissolved all of his clothing with the power of the stone. He begins to feel his new slave's powerful body that's more attractive to his taste. Thanos couldn't help but moan as the memory of sexual orientation conditioning and pleasure service training flooded and solidified into a part of his mind. The hours of painful neuron redirection surgery of nanobots surrounded by medical slaves bind his lust, love, attraction, obsession, and sexual worship only to his rightful owner. Sessions of training with his senior honor guardsmen to master the art of sexual service, to be to the standard of the honor guard that has a holy duty of pleasure to the god master.
The master locks his lips with his new slave. The slave's expertly trained tongue warps around his master's and dances with precision and skill to maximize the pleasure of his master.
His inside is self-clean and now wet with lubrication that the master modified his body to produce. The master rams his manhood into his living fleshlight, They both moan with the same source of pleasure, Toby's. The slave's own pleasure is trained and eliminated out of him along with his free will long ago. He only exists to serve, not feel anything but the pleasure from obedience. "When I cum, you'll purge all muddle noises of the man that no longer exist. Only my will fill your soul or your purpose and core existence. You don't exist, only a vessel, an extension of my will, Weapon-T."
The master groans, to the well-trained sense of the slave, he knows that the master is close to releasing his holy seed. The master buries his full length onto his slave and releases his seed deep inside not only the slave's body but also his soul and mind. And as commanded the slave body pushed its own seed out along with the existence of Thanos. The stone glows and seals the slave's fate. The mad titan never existed, only Weapon-T created and trained on this planet to enforce his master's will throughout the universe with the same power and abilities the purple giant has except for the stones which have always belonged to the master. His body was repackaged into a more attractive form to serve his master in another more intimate duty.
The master pulls out of his slave, as he looks up instead of the city park. The greenery is surrounded by a huge courtyard of a gorgeous building that must be a palace, place of worship, or something along the line. Weapon T resumes to parade rest position. His hands behind his back, waiting for his next command. Naked except for his collar and full erection, a proper attire for the master's palace. His own cum still splattered all over his eight-pack and pecs; master's cum and his own wetness leaking down from his hole to his powerful legs; his penis are glistened with the residue of his cum and pre-cum. He'll let it dry into his skin. A proud mark of his obedience to his master.
The master turned his gaze back to Weapon-T. The slave immediately kneels down as the master's attention turns to him. "Where have you been doing before coming here, slave?"
"Guarding you at the throne room, sir" The slave answered. He would have feel some confusion on why did the master ask him this. He's the master's honor guard, of cause he follow him back form the throne room to the garden in his private quarter, but his free will are non-existence, so such thought does not arise.
"Good." The master said nothing more as he turned to the courtyard corridor and looked out the windows of his palace. To see that the garden actually sits high above the city. As he looked down, the busy city he used to was all gone; a combat training arena, gym, breeding center, barrack, weapon, and vehicle depot filled the skyline instead. People who walked around lived their normal lives are all altered. Their 9-5 jobs, family, and relationships that they used to have mere moments ago have become such an alien and unheard concept for them. To them, it always has been this way since they were born, bred, and trained to serve their master in every of their breathing moment, just like generations of slaves before them. From what the master sees from afar, all slaves walking around the city are in their peak physical condition. Their brutal training and gene enhancements ensure that they are capable of performing their master's tasks perfectly. After all, this is not their body or mind, it's their master's, a vessel of his will, and he molds his possessions how he wants and it must be always ready to be used.
Weapon T resume to guarding position beside his master. The city are the same as yesterday, it have always been his home and his purpose of existence. Where he was created, trained, and serve his god master, along with other 7 billion slaves.
