Becky smiles at you, and begins to gently guide you to your knees. "Just go with it, Jen. You don't want it to have to be the traditional way. This feels much better for the both of us," she tells you, as she pulls you by the hair toward her crotch.
You can feel the heat radiating off of her vagina even more strongly than the rest of her body. You smell the odor of her...it's sweet, and exotic. As she guides your head closer to her crotch, you smell it more strongly and your head begins to swim a bit. You've got a light buzz, almost. You start to wonder how it tastes. You stick your tongue out, beginning to lick around her labia, tasting tiny droplets from her. Becky's grip on your hair tightens, and she shoves your face right up against her. The drops on your tongue cause an almost electric sensation to go through you, and your head is most definitely swimming now. You begin to lick more aggressively now,and you can feel her pussy beginning to twitch and pulsate.
"Yess...grrr...yesss.." Becky says, growling slightly,beginning to grind herself against you. Musk begins to pour from her vagina, and she spreads her lips against your mouth, encouraging to lick deeper. You comply even more eagerly, grasping onto her thighs, feeling them twitching and growing furred. Brown fur is blossoming on the flesh beneath your fingers and your face as you work your tongue in her most intimate of regions, smelling only her scent and tasting only her juices.
"Make...me...howl...make...me...change...make me CUMMMRRRRAAHHHH!!!!" Shouts Becky, her nails growing into talons as she holds your head in place. Her voice is low and feral-sounding,and she continues to grind with more and more energy against your pleasuring of her, until she erupts in another howl, and cum and musk gush into your mouth like a tidal wave of infectious liquor. She pushes you down onto your back now, dropping to all fours in front of you.
Her eyes are blazing amber, and her mouth is filled with fangs. Six teats hang from her chest, which is covered in a mat of brown fur. Her body is still swelling, reshaping into the form of the beast, the flesh popping and pulsating, the bones stretching.
She smiles at you, growling out a "Now...you...join...ussrrrr..." as her face begins to change more. She buries her face between your thighs, licking your vagina hungrily. You grab onto her hair as she does, feeling her face changing, stretching into a muzzle between your thighs. Her muzzle begins to penetrate you, her tongue reaching deeper than any human's ever has before, and you moan helplessly as you stare up at the moon, wracked by orgasm after orgasm. She takes you to plateau after plateau of pleasure, able to wrap her tongue around your increasingly swollen and sensitive clit, licking every bit of it again and again.
Finally, you can take no more, and breathlessly you gasp, "Do it! Do it! Make me one of you! Make me an animal!" You grab the back of her head, pushing against her muzzle, hoping to feel her fangs against your skin, and you aren't disappointed as she pierces your clit with one of her fangs, causing you to convulse in pleasure, unable to even moan as you experience the biggest orgasm you've ever had.
