Tell her how much she loves cum.

Emma hasn't given you a blow job in like six months, and when she did it was half-assed, like a few licks before moving on to sex. Every time you watch porn you're reminded how Emma never sucks you off - and you'd like to finally change this.

"You know, you are a such a fucking cocksucker, Emma," you start telling her in between thrusts. "You think you are a progressive modern woman but what you really want - what really satisfies you is being on your knees in front of me with my cock in your mouth."

Emma seems surprised by what you're saying, but you continue.

"You don't want me to hold the door open for you, lay my coat down over a puddle, or even pay for dinner. You want me to fuck your face. You want me to pin you down, straddle you, and **** my cock deep down your throat until you can't breathe. You feel complete chocking on my cock. You are one twisted cunt."

Emma seems to be responding positively, which gives you the confidence to continue.

"Have you always been a cock slut, Emma? When you were a little girl did you want to grow up to suck big fat dicks? Did you touch yourself wondering if it was true what they said about black cocks? Did you find yourself sucking on lollipops, pens and pencils, and your thumb far more than the other girls? Did you get an early start playing doctor with the little boys in the neighborhood? Nothing would surprise me at this point, Emma."

"I've seen the hunger in your eyes. I don't know if it is for my dick or if any fat slab of cock would suck satisfy your oral desires, but it doesn't matter because I'm not going to stop stuffing your face. I'm hardly going to let such a primo catch slip though my fingers. I'm going to hold your head tightly in its place."

Emma is moaning now and licking her lips.

"I know you drool like a dog at the thought of my cock in your mouth. You long to wrap your saliva and your tongue around it. You want to taste it. You work hard to please me with your mouth, snapping open your jaw, shoving your nose into my pubic hair, deeply breathing in my strong scent. You like it when I help you take more by wrapping my hands around your hand and pressing you toward me slowly."

"My cum is your free toy at the bottom of the box. It's your prize. Sweet. Sticky. Delicious. It's nectar of life. It purifies you after the depraved desires you have acted upon. You want to twist my cum around your tongue savoring the taste. You want to bathe in it. This is because you are and forever now will be a cum slut. You'll never stop longing for my cum, the feel of it pumping into your mouth, shooting to the back it your throat or dripping down onto your tongue. Hot. Precious. And never enough cum for you. This is why I know you, my dirty little cocksucker, will always be back for more."
