The Usurper gently pushes the feminized knight Leon aside while she reluctantly slid her hands away. As he turns towards you, your gaze is transfixed on his glistening, swollen rod. Before you even realize it, he begins to pull your chain, forcing you to crawl towards him on all fours.
"Come, slave."
You don't know if you're hearing the words or if they're simply manifesting inside your head. The collar pulses gently, again and again, making a warm and fuzzy feeling flow through your body from your neck to your toes. Seemingly on its own, your body moves, crawling across the floor ever closer to The Usurper. You begin to put together a thought as collar's pulses fade, trying to think of a way out, but just as you begin to tap into the power of The Seal of Knowlege...
"Stroke it. Please me."
..the collar pulses again. His orders are become your new thoughts, and wamth washes over you as your mind switches from anxious struggle to willful obedience. You pause at first, a cloistered princess with little experience, but your hands begin to move by themselves. Gently, you wrap your fingers around The Usurper's cock, reflexively cooing as you feel its warmth quickly radiate through your silk gloves. Excitedly, you shift your weight to more comfortably attend to your duties, sliding your royal dress over your ever-hardening and sensitive nipples. This new train of thought makes it to The Seal, and your mind is quickly flooded with lustful experiences from its past users. Soon you're deftly sliding one hand up and down his shaft, eagerly licking precum from his tip, and fondling his heavy testicles.
"Mmm. I can see that The Seal of Knowledge has--", The Usurper grunts in the middle of his statement as you quicken your pace and meet his eyes with yours. "Has... provided me with a most interesting new slave--", again, he's interrupted as you begin to pump him in earnest. Hearing yourself referred to as "slave" in your current state--horny, captured, and constantly conditioned by the collar--drives you wild. You need to please him. You need to be his slave.
"Make me cum, slave."
Without hesitation you quicken your pace yet again. Then the collar pulses, imprinting the idea upon you once more. When you feel pressure begin to build up in his cock and you instinctively pull your face back and open your mouth wide. His cock pulses slowly as it fills more and more, releasing small beads of precum that drip down to your chest, while you keep going without missing a beat. You bring one hand down from his balls to your breast and earnestly begin squeezing, finding that your nipples as hard as diamonds. All you need to become a true slave is for your master to cum... to... to serve your purpose.
Just as you think it, it happens. His cock jerks and pumps, shooting load after load of hot cum all over your face. Your newly experienced mind instinctively closes your eyes just as it begins, while you guide your open mouth and tongue to catch everything you can. He's a beast... a giant, and your face is quickly covered, your mouth full, and streams of cum run down your chin to your neck. Slowly you slide your hand away from his slowing penis and down towards your other breast, massaging them in unison. You swallow the warm load in your mouth, drinking down your master's cum willfully. Now you're a slutty mess, collared and coated in your master's cum, desperately massaging your tits through your dress because of uncontrollable horniness. You want to cum so bad...
"Mmmm... that was amazing. The Seal of Knowledge really did a number on you, princess. You emptied me out, and now you're desperate to cum. Unfortunately for you, that collar won't let you unless I will it."
You audibly gasp in horror, but can't stop yourself from sliding your fingers to your nipples and gently squeezing, trying harder and harder to push yourself over the edge.
"But I will let you... that collar has four seals... each one activated by the energy of an orgasm from the wearer. Every time a seal is activated your enslavement deepens, changing not only your mind... but your body." he brags, as he briefly glances at the bashful Leon. "All that remains is for us to activate the seals, and you and The Seal of Knowledge will be mine forever!"
He's going to enslave and transform you, but you don't fucking care! You just need to cum!
"Now cum, slave!"
