Embrace your lust...

 You're glued to your chair, enthralled by the sight before you.  Jess's once shoulder-length blonde hair has become the darkest most lustrous black you've ever seen and it now nearly reaches her ass.  Her exquisite figure is now completely flawless.  Her freckles have vanished along with every blemish and scar she ever had. Her once tanned skin now a dusky shade of crimson and her once modest B-Cup has developed to a DD, her now-black aureoles prominently displaying her rock-hard, inch-long nipples that have to be as thick as your thumbs.

   When she was human, Jess loathed giving head, much to your chagrin.  Now you watch raptly as her serpentine tongue coils around your cock, pulling you into her mouth to the hilt.  The sensation is an indescribable union of an expert handjob and deepthroating.  You look into Jess's now-slitted emerald green eyes, and the insatiable lust there pushes you over the edge.  Your moans turn into a roar as your hands clamp down on either side of Jess's head and your hips begin to buck, cumming harder then you ever have in your life.  Her right hand cups your balls and begins to knead as her tongue strokes your still-deepthroated cock, milking you as you come in waves.

   Jess continues to stroke your cock with her tongue and massage your balls with her right hand for nearly a minute after you finally stop cumming.  You feel her tongue unravel from your cock and she slurps her way up your length, her mouth finally leaving it with an audible pop.  She immediately begins to moan in pleasure, arching her back like a drawn bow, as her right hand leaves your sack to join her left in feverously rubbing her clit as she fucks herself with her phallic tail.

   You suddenly realize that after the most incredible orgasm of your life, your cock isn't limp, but harder then ever!  It even looks bigger then you remem--uh-oh.  You begin to notice your skin is gaining a crimson hue, and that your nails are turning black and lengthening--you've been infected!  Your mind starts to reel... you feel at war with yourself.  You feel... you feel?

  "You feel it, don't you?"  Jess whispers huskily in your ear.  While you were lost in thought you didn't notice Jess straddling you.  You are acutely aware of the heat emanating from her dripping wet snatch scant inches from your manhood.  "The uncontrollable urge to pleasure yourself.  The burning, throbbing need?"  There is urgency in her voice.  "Surrender to it," she purrs as she rubs her slit against your throbbing, lengthening cock.  "Join us," she moans as she guides your cock to her mound, the tip of your cock just barely parting her pussy, her warm juices flowing down and lubricating you.
