Todd screamed, tears streaming down his face as his body violently transformed. His legs flailed uselessly at the ground as he felt his internal organs being subtly reconstructed. He could only watch as the male werefox who had done this to him now settled his body on top of his dear Astrid.
Astrid's own eyes went wide as she felt the werefox's member begin to explore her own now-furry thighs. She tried to speak, to move, to do something to prevent her own rape, but there was nothing she could do... her whole being was burning with the change she had been forced into, and all she could do was try to grip the earth with her transforming appendages and try not to lose her sanity. A desperate, growling moan of protest escaped her now-fanged mouth.
"You're mine now, vixen," said the fox who covered her as he placed the tip of his maleness at her vagina, which was hot with the heat of her change. His tone was calm, without any doubt, nearly mocking her helplessness as she lost her humanity, knowing that she could not escape him. And then, he took her.
"Nhhhrrrghhh!" cried Todd as his girlfriend was raped in front of his very own eyes. "Ahhhstriiddhhhh..." he tried to form a word through the pain. Something was happening to Astrid... with every thrust of the male's rod into her, her changes seemed to increase. Her ears had grown long and pointed, and were traveling up to the top of her head. Fur was now spreading along every ridge of her sweating, heaving body. Todd watched as the breasts he was so fond of began to swell, and then multiply, new breasts popping up on her chest and filling with flesh, bouncing back and forth and against each other to the rhythm of the powerful male who was dominating her. He didn't feel it due to the pain of his own changes, but his own penis was hard, erect, and swelling to a larger size than it ever had, watching his lover be mastered.
"Yes, that's it," breathed the male werefox into his submissive mate's vulpine ear, encouraging the changes she did not want. "It'll be over soon." Even as the male spoke, Todd watched his girlfriend's face slowly, slowly, press outward, the bone cracking and flesh warping to form her new muzzle. A final choked cry from Astrid, and she was human no longer.
To Todd's horror, Astrid's long, pink tongue hanging out of her mouth and the way her eyes rolled back made him think that she was actually beginning to enjoy it. His face, already partially erupted into a canine form, allowed him to smell the scent of female heat, and then, as she animalistically began to grind her hips back into the male who was mounting her, her tail curled out of the way to allow him access, she began to yip rhythmically. There could be no doubting the meaning of her cries; nothing meant anything to her anymore but the sensation of the male inside her, the animal rut, her burning heat.
Todd closed his eyes, bracing himself for the end of his own change that he could feel twisting his very being at its core...
