"Yes, oh yes! I want it so bad!", you scream outloud. Pleading, “please change me into a vixen so that I can bear our young and be fucked by you whenever you want. Make me your mate please!!!”
“Now that is perfect to hear” he growls at you in pleasure.
He ruts into you as hard you can, your changes going much faster as a tail starts growing out, and red fur spreads over your body. Your hands gripping yourself to him change into paws with claws, their pads gripping against his fur, as you buck your cunt to him, trying to get him knotted in you. You hear a wet plop as he pops into you, making the thrusts even shorter.
Your muzzle completely forms as you lick his face, a black nose forming on the tip. Images of mating with him filling you with bliss as you keep bucking. “wonderful…” you say shivering in pleasure, as six fur covered breasts form on you.
“once I cum into you, you will be my vixen forever.” He growls giving your new triangular ears a little nip.
It takes only another moment, before you feel his seed shooting into you and you can feel the last change, your eyes turn golden as your pupils slit, even as your body orgasms in bliss.
Coming down from your high, you grin as you groom his face. “A perfect mate to fuck me whenever he wants, to slate my heats and to give me plenty of litters”
