"I beg your pardon?" you ask, your hands covering your privates. The fox-woman giggles in response
"You can have your clothes back, after you mate with me." she says. Getting closer. You consider it for a moment. Her body does look attractive, but in a strange way. It's the kind of attractive you wouldn't ever really admit to anyone. Still with all that's happened, your clothes being stolen, walking naked through an area that's a bit colder then you're not entirely interested in sex. She seems to read your reluctance on your face and continues walking up to you, her grin almost seems predatory. You end up backing away from her. When you collide with a tree she presses her body up against yours. Her hands rest on your sides and slowly slide down.
"Don't worry, I have ways of making you interested." she says. The fact is you're already becoming a little more interested. That and the realization that you can't just walk around naked make you nod your head.
"Good." she says "now, just take a niiice deep breath." she says and pushes herself even closer, guiding your hands away from covering your crotch and around her back. Your hands naturally rest on her rear and you can feel her big bushy tail brushing against your forearms as she swishes it back and forth. You follow her instructions, taking a big breath. You do smell something, a scent that you're unfamiliar with. The fox-woman's proximity and her rubbing seem to be having an effect on you, but so does whatever that scent is. You find yourself breathing more of it in.
"Pheromones." she tells you. You can smell them even sharper now, so much so that you nose begins to tingle inside and out all the way down to your cheeks.
"They work on humans?" you ask.
"No." she says "But they work on people turning into foxes." she says with a mischievous grin. You feel your nose changing, becoming smaller. Your face begins pushing out as tickly fur begins pushing out from beneath your skin and onto your face and cheeks. Your ears twitch as they begin growing to points and shifting higher on your head as fur spreads across your face and up around your head, swallowing your regular hair. The feeling is strange but with each inhale of the pheromones you feel yourself becoming more and more aroused.
"Wait, no. You said I had to have sex with you, you didn't say anything about this." you say. You try to push her away, but she determinedly clings to you.
"I said 'mate with me'. I can't have babies with a human." she says and cups her hands behind your neck "Now don't worry, you'll enjoy it I promise." Strangely, she's right. You're skull shifts as your muzzle completes itself and your teeth grow to points, but there's no pain. Your neck begins growing fur beneath her hands and she rubs her hands over it gently. You close your eyes as the fur grows around your neck and down your back. You're enjoying it so much that you find your hands wrapping around her waist and pulling her even closer. You try to adjust yourself to enter her, but she backs away.
"Now, now, not until your finished changing." she says. Her hands move down to your arms as you see fur grow on them as well. Her smell is clear now. You're mind isn't focused on your disappearing humanity, only on putting yourself inside her. You try to close the distance again, but she steps away again giggling. She turns around showing you her swishing tail and wiggles her rump teasingly. "Ooohh...so eager. You want this now?" You step towards her, and reach out. As you do you see the flesh of your fingers disappear beneath red fur. Your torso and back are now covered, and your tailbone has a dull ache as a lump forms. She pick up your clothes, as she bends over she wiggles her rear again and looks back at you. You run after her. She shrieks playfully and begins running away from you, giggling all the way.
As you chase her you can feel your body continuing to change. The tail grows out more and more and your legs and feet change, forming paws and fox like legs as the fur crawls down them. This makes you even faster and you finally begin to catch up to her. Just before you reach her she drops your clothes, turns around and lunges back at you. You collide in a tangle of limbs. Her warm body and powerful smell arouse you to levels you've never felt before.
"Now you're ready." she says and helps you guide yourself in. You instantly feel an incredible sense of pleasure, as her arms legs and vagina clamp around you. You loose yourself to the pleasure. Whether it's minutes or hours of love-making you don't know, but eventually you find yourself releasing yourself into her. She moans and climaxes with you, clutching on to you as you unload yourself into her. You lay there, both of you panting. She slides her arms up to your neck and nuzzle your new face "There now. You're part of the bargain is done."
"Can you take your spell off me?" you ask.
"No. I can't control that. My pheromones changed you. Stop sniffing them and you'll change back. Sniff too many and you'll be stuck like this forever." she says.
