The feeling of his cock entering you is incredible, impossible to ignore, and consumes all of your thoughts. You should be resisting, you should be scared, but the slightest shift of the fox man's cock in your nascent pussy floods your mind with pleasure. Your arms remain braced against the ground, holding up your trembling body. You find yourself pressing your hips down, slowly but surely pulling the fox's red hot meat into you, and gasp helplessly as each jolt of pleasure hits your mind.
"Y-y-y-yeeah... oggghhhhh..." you moan as the fox enters you deeper, sliding into you centimeter by centimeter as your body slowly changes, opening a warm moist tunnel for him. Between slow gyrations a mixture of curiosity and lust compels you to look down again. The sight of the cock buried inside you drives you wild with a mixture of emasculation and horniness, triggering a wave of heat and wetness in your pussy, and you watch in awe as you watch more of his cock disappear inside you. With every slow thrust down the cycle repeats, filling your head with pleasure and your pussy with heat until finally something catches on your new vaginal lips.
"Grrrryesss..." The fox man snarls, "...you're doing just great, human. Such a natural slut."
The word 'slut' triggers something inside you, and you let out a little whimper while you hump once more trying to get him deeper inside.
"It's easy to tell... you want more. But I'm already up to my knot in you!" he snarls, continuing to taunt your overstimulated mind. Your body wants it in, and your mind is too overwhelmed to think. Your sensitive tunnel throbs with heat, gripping his cock tightly and rhythmically, causing his cock to swell rhythmically inside you in response. He slides his hands down your body and around your hips as he continues, "If you keep going, and my knot gets inside you, there's no stopping until you're full of my cum..."
"Y-yeah!" you yelp, in a sharp feminine tone. Being filled with the fox man's cum sounds like an amazing idea to your aroused mind. You hump him once more, now willingly trying to get the knot inside.
"Hahaha..." he chuckles in response to your desperation. "You want it so bad, don't you?", he continues, gripping your hip and squeezing your ass with his huge padded hand. "You want to become my vixen and take load after load of my cum, don't you?" he taunts, firmly holding your hips, preventing you from successfully forcing him into you. He just keeps teasing you, letting your pussy wrap around his knot slightly before pulling you back away. You feel soft fur brush up against your face and hear: "But I won't give you what you want until I own you completely, bitch"
'Bitch'. Another keyword elicits another helpless moan from you.
"Say you're my little bitch," he rasps right into your ear, while lifting his hips slightly and gripping yours, "Say it!"
"I'm... ya... your... little.." you stammer, gasping softly between words. The closer you get to completing the phrase, the further he pushes his knot, and you feel it almost pop in. A shadow of a doubt passes through your mind as you realize the finality of it all, and you stop just short of his demand. Your last resistance is only the weakest of whimpers: "No, I'm... ogh..."
"What was that, vixen?" he retorts sharply. Suddenly, the fox man releases one of your hips and slaps your ass firmly. It stings for a moment but the more alarming thing is how your butt jiggles afterward. You suddenly become aware of how feminine your ass is, how much you've transformed into the fox's plaything, of how deep he is inside your pussy, and it just overwhelms you. You're ready to exclaim the truth for him.
