You're in the same position you started with; on all fours over the fox. The same position you shifted into when you wanted to take control, to reverse the process while the fox changed you, but all it managed to do was make him hornier. His powerful cock pushed, pushed, and pushed until your body opened up and let him in. All the while you blindly kept grinding and willed the entire proess along. Now your legs are spread, his cock fills you completely, and your pussy grips his knot tightly. You have to do something...
You reposition yourself slightly, trying to pull your hips way, only to painfully realize how tightly bound your pussy lips are to his knot. A feminine yelp escapes your lips and slips into a moan as you grind back down into him, rubbing a sensitive spot above your vagina with intention. You try to pull away a couple more times, your mind a mess of fear and pleasure, only able to move just a little bit before your resistance wanes and you push back down again, stimulating your nascent clit.
"Don't worry, my dear, soon _he'll_ be gone, and it'll be just you and me," the fox quips in response.
The fox man's words frighten and delight you... he's not going to stop until you're something totally different. It's horrifying... but it feels soooo good. Your hazy mind quickly takes that fearful energy and converts it to action, pulling back against the knot, then grinding into him. It feels even better this time, and you start to enter a new rhythm; pulling, grinding, and arousing yourself more each time. Before long your desire to pull away has faded completely, and you're back to being nothing but a lustful, needful bitch.
"Y-yeah!" you exclaim, just as you rub your hypersensitive clit into him, needing more and more. Even the fox man can't hold back completely anymore, and he begins to push back into you along with your thrusts. His cock swells with power and warmth inside you as it pushes in, filling you completely and forcing another wave of hyperfeminine energy into your body and mind. "Oh y-yes!" escapes your lips in response, and your whole lower body clenches tightly against him...
"That's my bitch," the fox man grunts as he pulls back to hump you again. "just imagine how good it'll feel when..." he continues, as he slides his huge hands up and down your smooth sides, over your newly widened hips, "...I pump you full of cum." With that, he pushes himself in to the hilt again and stirs you up inside, reminding you of the incredible warmth and wetness within. Something deep within you needs that cum, and despite some pesky part of your mind being deathly afraid of letting it happen, your body responds on its own and clamps down tight.
"Fill me with your cum master!" the bitch cries, completely out of control, now obsessed with her new prize. "Yesss..." the fox man responds as you both thrust in unison, over and over again, with what limited motion you can while docked. "Make me your bitch! Please!!" you continue, spurring the fox man on. He simply growls animalistically in response, and you feel his cock throb once again, filling with cum, while he quickens his pace. Everything's on automatic now, both of you panting in passion and heat as it all comes to a climax.
You feel it; the final twitches of his cock within you before he releases, and you let out another incredibly submissive declaration in your hopelessly feminine voice.
"I'm your usable BITCH!!"
With that, an incredible pleasure washes over your body and your mind empties.
You are his usable bitch.
Just waiting to be filled...
With a last deep thrust he pushes all the way into you, swells with heat, and then releases inside you, again and again, filling you with his red hot essence. Your body clenches and pulls hungrily at his cock as he pumps into you, beginning to sate the incredible need that had built up within you during the transformation process. He grips your hips tightly and pulls you in each time, making sure to send each red hot load deep into his new bitch. Red hot splashes of pleasure release into you continuously while his cock busily fills your newly formed womb up with his seed. After what seems like an eternity, his orgasms seem to slow. But just as you begin to catch your breath and clear your mind, the fox man clenches one last time and sends an impossibly hot final load into you.
You're finally full.
