"My genitals."
You release held breath. It is sort of a relief, after what you'd been threatened with... though you still blush at this admission, as though you wanted to become his cock.
Maybe because... looking at that proud red member... you do.
Regardless, you manage a protest. "You can't be serious!" You look over at Janice, not sure if this is her doing; but a bit more willing to beg of your old friend than this arrogant fox. "Janice, is that what you said to him!? Can't you --"
"I'm just a stupid whore, remember?" she answers tartly, eyes teary and smouldering still. "What do you expect me to do? Be grateful the Prince is giving you such an honour. People would kill to be his beautiful flesh -- if they had any sense."
"You --"
Suddenly you find the Prince's finger on your lips, and your words fade to an inarticulate whimper. "Cocks have no need for speech," he teases. Your eyes meet, yours seething with rage and fear, his bright with anger and power. It is not long before your gaze slides away, your head declining as much as his spell will allow.
This little contest over, the Prince steps behind you again. "Had this one any sense," he says to Janice, "he would not be in this position. But he'll learn."
He presses into you now, your skin flinching as you feel his hot loins against your butt; the kiss of his wet tip on the small of your back. Hands set on your shoulders, pads and claws holding your flesh as though it already belonged to him.
"Ready?" he asks, still teasing. He makes a show of waiting for an answer as the other vixens gather around Janice, tails wagging, the whole harem eager to see this new display of their master's magical and sexual prowess. After you force a few indistinct sounds from your mouth, he laughs. "Ah yes, of course; how could I forget so quickly that cocks cannot speak? But they are always ready for fun... so I will not deny you any longer."
You make one last futile effort to struggle, or at least beg him to reconsider. Now that it's come down to it, your pride doesn't seem worth it. But it's far too late. You can feel his cock sinking into you. The fur from his ballsack part and spread over your buttcheeks, his bare skin touching yours for a moment until the division is gone.
Heat rushes into you with his blood as it invades your veins, subsuming your own vital fluid. Your heart seizes painfully -- and then it is pumping to HIS rhythm. The room begins to get distant, larger; the vixens murmuring in awe, seeing your upper body flush with the Prince's arousal, while soft white fur has nearly claimed you from the groin down. Your cock is now erect, throbbing, bumping at your belly, straining with his blood despite how sick you feel.
You realise that you are shrinking. Also that when the prince said "genitals" he did indeed mean the whole package. Your buttocks are already starting to feel... baglike; hollow, and to your shame your body tingles with anticipation as two solid, egg-like masses press down into you, one to each empty asscheek, feeling larger and larger. Your own testes slide inside, moving to merge with those claiming you.
Your limbs melt away rapidly now; legs diminishing to nubs as fur consumes them before vanishing entirely into what is clearly a scrotum; arms pulling up, bones fading. Your own isnignificant cock sticks to your belly for a second, flattening out and elongating, the shaft disappearing into the white fur sweeping up from your hips, the head fusing and... spreading... into your chest.
"Ahhhh..." The Prince's hands on your shoulders have been getting steadily bigger relative to you. Now as your flesh grows smooth and sensitive, he begins to stroke along your torso. You feel his purr rumbling through you, mixing with the sound of his blood rushing in your ears -- what's left of them. The little flaps of your arms finish resorbing into your body under his ministrations, as do your features -- hair, ears, eyes, nose; all fade into the delicate, dark red skin of a canid shaft.
The only thing left is your mouth. And now your voice fails completely as your whimpers turn to burbles of pre-cum, which is unexpectedly sweet as the Prince's fingers squeeze it out of you. This causes you to realise that he has fulfilled his promise to leave your senses intact -- just as you can taste his pre without a tongue, so you can see without eyes. They're a bit blurry, but you can make out the gathered vixens panting for the cock you've become.
Yes, it's effectively over for you. Your lower body hangs between the Prince's legs, filled with his balls. Your skin has become the sturdy walls of his sheath. Your sides have puffed out into his thick knot -- and God does it feel good when he squeezes it. Your torso has become his shaft; your bones, his baculum; your organs, his urethra. Your head has become his pointed dickhead. All that is left is size, and after a few seconds more under Karther's heavenly fingers, that is taken care of as well -- his magnificent cock and balls have returned unchanged.
Only they are now your body, rooted deep inside his. Sharing inescapably in his pleasure -- indeed, feeling even more keenly the thrill of his touch and the weight of his balls, eager for release, for that is now your entire world.
But all that mass has not been wasted, oh no. Your flesh has been converted to sexual energy, to fuel the Prince's stamina and keep him going -- indefinitely, had he not other duties besides caring for his concubines.
And, as your flesh is now his flesh, you feel Karther's spirit pervade you. His mind looms over yours; his lust roars through you like a flood. And you have the uneasy impression that he is completely aware of every thought you have.
Although, perhaps that means you could...
Karther? Cowed for the moment, you try to reach out to that mind -- having to concentrate to shut out the hard power that stiffens your body and the hunger surging from your balls.
-Yes, cock, I can hear you, when I choose. But it is not meet that my flesh should make such demands on my attention. So this is the only time I shall answer your summons -- henceforth when I desire converse with you, I shall be the one to begin.-
And with that, it seems, a door closes between you. You still feel that he is aware of you, and you are certainly aware of him. But you cannot intrude on his mind any more.
He had been gazing down at you. But now, having delivered his final admonition, he lifts his lustful eyes to his concubines, and smiles.
"Did you enjoy the show, ladies?" He gives you another squeeze -- and you know what will come next. "I think this new cock needs to be broken in; who would like to do the honours?"
