"You can call it a slave stone, you pour magic inside of it and the person staring into it will be enslaved to your will. The process is extremely simple." She took a plain grey rock from among the pile and showed it to the man.
"That sounds completely unrealistic. Is there a time limit for how long it will last?" He snorted at her as he visually inspected the stone.
"That depends on the person you use it on. It also varies based on their actions during enslavement. If the person is of strong will and defensive it could be no more than a few minutes. But if done correctly it could be forever." The seller traced a pattern along its dull surface with her finger, the excitement visible in her eyes.
"How much?" The man couldn't help but start the deal negotiation. Despite the fantastical nature of it he couldn't contain the excited gaze if it was real.
"Considering everything, this can only come out to two platinum a piece." She proudly set the stone down onto the counter between the two and looked expectantly at the customer. He sat silently for what seemed like forever. Staring into her face unflinchingly and making it just slightly uncomfortable.
He stared intently at the stone hoping to judge its authenticity, at first she wondered if he would pass on getting one because it was so expensive but instead something in his eyes gleamed as he came up with an idea.
"I'll make a deal with you!" He exclaimed moving before she could react to stop him from stealing the stone, "I'll test out if its real for free!." He held the stone in front of her face and poured out a whole reservoir worth of magic into the item.
She didn't try to look away from the stone, completely calm despite his actions.
"Wait NO!" It was only a few moments later when her eyes suddenly lit up with light and her pupils went blank.
"Holy shit!" He blurted at how easily the woman submitted, any thoughts of doubt immediately evaporating. "This actually works..."
Her pupils morphed into the shape of hearts before changing in color to a light pink. "I'm ready to serve Master however he so desires." A complete turn-around of personality that was shocking coming out of such an elitist looking woman.
"You'll do anything I want?" he said smirking while feeling very daring.
She pressed her body against his, breasts pushing against his chest. Hands wrapping around him from behind and a beautiful, almost hypnotizing face looking at him directly in the eye while lightly licking her luscious red lips. Her voice lowered as her breathing got deep, "I will do whatever Master wishes." She licked the shell of his ear playfully earning a moan from him.
"Before that, how about you tell me more about this stone first. You mentioned there was a correct way to use it." Having this stone felt like power rushing right through him, though he had just made one female his slave how much better would a harem be?
"Of course my love~" Her face expressed a mixture of subservience and faux affection while her ass sticking out suggestively behind her. "The process of getting someone to have their will altered goes as follows, first the enchantment needs to connect from your stone to their retina. When they cannot look away it gains mental control through direct sight."
"It only works on people of the opposite sex. Next, the master will infuse their mana reserve into the stone, and depending on the purity of his magic it decides how long the enslavement lasts. To get it to last forever as Master desires, he will need to claim his slaves before the spell runs out."
"Claim her, you mean...sex?" he chuckled while bringing his hands to cup her breasts together. It seemed a lot less shameful of an offer now with such a beautiful woman grabbing onto you, giving off slut vibes like she was basically begging to get it.
"Sex is only part of the claim as you need to cum inside them to inject your mark onto them. You must also drain the slave of all her magic before the spell runs out. If they have no magic power to resist the spell it will engrave itself onto them forever." She continues to tease his neck, flicking out her tongue to slowly taste along his skin in an arousing way. Her hands meanwhile played around with his back by sliding along it gently or scratching the skin lightly whenever he grew close to certain areas. "Can we have sex now Master? I want to have sex."
