Begin the transformation

Iris finishes pulling down your underwear. "Well, now let's take a look since we go-OHMYGOD!"

She looks up to realize that your rather large cock has come into view. She can only stop and stare (and drool a little, but she doesn't notice that) at the specimen in front of her.

"See something you like?" You say, knowing full well that she is just about yours.

"Your dic--I mean, I have to continue with the examination...yes, continue..." She mumbles.

"You can lick it if you want."

"I..can't, but its...sooooo...delicious..." She can't resist as she slowly opens her mouth and engulfs you in her warmth. Your precum has been leaking out, already infecting her. You can tell by the way she goes from a lick to a full-on blowjob. Her eyes go from a meadow green to a blood red as she goes mad with Lilith Strain - induced lust. She tries to completely take in your cock, but only gets about half-way down. Up and down she goes, swallowing more of your pre-cum.

"Sooo good! I want more!" She says, taking a breath and returning to the task at hand. You oblige her by grabbing her fiery red hair and forcing more of your cock into her mouth, making her gag. Undeterred, she deepthroats you, the sensations driving you wild with raging lust.

You notice that as she's blowing you, she has a hand down her uniform and switches off between fondling - no, near mauling - her breasts and madly rubbing her clit.

"Soon...soon, she will be one of us..." you think to yourself as the contents of your balls begin to rise up through your dick. You begin changing into your demon form, skin turning red and eye becoming slits. Alas, your change is unoticed by the nurse-turned-cockslut. You can hold off your climax if you want to, unless you feel like giving her a nice facial...
