An animal whimper is your only response, your lips darkening as your jaws stretch out, your teeth becoming longer as your nose turns black, tipping your new slender muzzle. He's right, though. No matter how much you try to tell yourself otherwise, it feels wonderful. Your legs spread by themselves, trying to help this male shove himself deeper into you, your body surrenering itself against your will.
Your back arches, your chest pushing out as your nipples swell, a pair of large breasts growing nice and firm, new nipples forming on your front in a pair of rows. And you should have them, since you're female and will be bearing young... It's nice to have a male who will help you when you're in heat...
You shake your head, trying to clear it of such thoughts. You don't want to give in! Even if it feels so nice... So big and so hard, pushing inside of you...
His knot is pressing against your tight cunt, as fur nearly covers your body. How much longer will this be against your will?
He bends his head down, licking and nibbling at your ears as they move ot the top of your head, becoming triangles with a light covering of fur on their backs, tipped in black. A shiver runs down your spine, making you realize it's a bit longer than before, a tail growing from the base of it with soft, bushy red fur and a white tip.
"It won't be long now. Once you take my seed inside you, you'll be my vixen forever..."
Mental images of being under him, of getting down on all fours and liftnig your tail, of standing with him and carrying his kits, flood your mind, filling you with pleasure. Your hands, now looking like paws with pink pads and short claws, reach up and encircle him, holding your body close to his with their black gloves of fur.
You cna't hold out any longer, it's just too perfect! You want him, you want this... Lifting your hips, panting and moaning in lust, you try to get his knot to enter you, your tight lips stretching a little more with every thrust of his. Finally, his knot pops inside, swelling and locking him into you, frantically humping as he tries to give you his seed. Your eager cunt clenches the knot, desperate to be filled with hot cum, needing to fulfill its purpose and mate.
And then it happens. Hot cum shoots deep into you from the fox's throbbing cock, sending you over the edge and causing you to orgasm, cumming hard as your entire body shakes. The warmth spreads through you, and something inside your mind tells you that this is your new body permanently, that your place is here, with your mate, and that you are his now. Both of you pant as you come down from the sheer bliss.
You look up into his golden eyes with their slit pupils, knowing that yours are a perfect match, a smile on his face. After what seems like an eternity, he speaks. "Nice little vixen... The more you fight, the more you become mine. A little vixen for me to fuck whenever I want. Isn't that right?"
You can only nod your head, smiling and licking your lips with your new tongue, knowing that he's right. After all, he's your mate, and you belong to him completely.
