You blink for a moment, trying to process what he's implying. "You're going to force me?"
He shakes his head as he slowly paces towards you. "No, I want you to look around at this world. Do you really think you can survive in this hostile land on your own, you can barely stand before me without trembling. Imagine how long you'd last once you run across a monster, or worse, how long do you think it would take before you starve? Or die of thirst?"
He moves forward to caress your body, and as you're frozen in place, you barely have time to notice as you already feel hairs beginning to poke through your skin; the beginnings of fur starting to sprout, your pecs feeling puffy, as if they're starting to begin growing into breasts, though they aren't yet bloomed.
You try to gather your courage, but it catches in your throat. "But... I... At least I'd be free... besides, can't you just send me home?"
He runs his hand across your face, it pulling out into a muzzle as he does so; then he ruffles your hair playfully and your ears seem to change into a more triangular form on their own in response.
"Its not entirely in my power to do so, I could barely bring you here at Janice's request, and that's only because you were already being drawn here; albeit slowly," he said, "at this point if you want to survive in this world, your only choices are to be cared for as a member of my haram, or to serve in some other fashion... And from what I hear, your current skills aren't suited to the other jobs we have available."
You manage to think of something, and you stare him straight in the eyes. "But your magic seems to keep you safe in this world, what's to say I couldn't survive if I figured it out myself?"
"Perhaps..." he starts, "but you'd need a mentor, and its not like you would have any way to repay them... Except with your body."
He punctuates this by running his hand along your crotch, in an action of smoothing out your junk like it were clay, leaving only a pert pair of lips behind as he seems to push the leftover flesh toward your tailbone; him soon massaging it into a sensitive nub that seems to be the start of a tail, growing ever more sensitive as he works it, as if he wants it to remain a reminder that it was once your old sex organ; your vagina seeming to puff out with a bit of moisture as he caresses your tail.
You shiver from his attentions to your tail, but consider what he's saying... "So I ether become some kind of sexual servant just because you say so, or I end up doing the same thing just to pay to find a way to live on my own?"
He picks you up in his arms suddenly, eliciting a yelp from you, suddenly feeling smaller and lighter as he does so, you're unsure if its because he's turning you into a girl, or if its his own strength, or if you're somehow getting younger. "That's not a very polite way of putting it, they're certainly a lot more than that to me. Though I suppose from your perspective that's how it seems," he says, "but I suppose its a close enough for making your choice... They live more comfortably than you probably would if you chose to become a magical apprentice to me instead; they eat grander food, sleep in better beds, have their every whim catered to... Though if you work hard at magic, perhaps you'd be able to gather some of your own servants to do the same for you... Though it might be a whole human lifetime before you can turn yourself into a male again."
As he talks, he seems to be carrying you to a back room with a bed. "This could be a tough choice for some, a comfortable life or a chance at eventual freedom... But either way, you can help tend to Janice's needs as well, and it's not like you don't have time to choose while I work on your arms and legs." He lays you on the bed and begins massaging one of your feet, creating a dainty looking paw where the ball of your foot was, as your heel seems to elongate into a digitigrade stance. "That said, it might be odd to have an older apprentice, maybe if you choose that I should let you keep the boyish look, make you a younger girl who could pass as my teenaged daughter. Leave you with breasts only about as big as you've got now."
You turn your attention back to your chest, they've ballooned into a couple of handfuls of perky flesh covered in a good bit of "floofy" fur making them look larger than they are; and you don't know much about their cup sizes... Perhaps a B cup? They look pretty large looking at them from above though, so they might be smaller. You find yourself letting out some aroused whimper as you grasp at them.
You should probably decide before he goes ahead and tries to give you extra breasts or something... Unless you're into that.
