You're not done with the teasing... But the demon is.

"Oh no," You have a mischievous grin on your face. "I want to explore a bit more... I don't think I've practiced this enough."

And to illustrate your point, you graze your tongue over to the tip of his head. Making his cock twitch and his breath catch in his throat. He laughs, "Seems that I may be too good of a tutor..." Then with a predatory smile he adds, "But you should know better than to tease a demon."

He reaches down and suddenly grasps your hair near its roots. Kris has a very careful grip on you, making sure that there was some initial pain from the the pull but it does not last. You gasp from the first jolt of pain, and he pushes his cock into your mouth when you do.

"Suck Casey." He commands. And you shiver with delight.

You suck. And even without being told to, you know to keep your tongue busy. You keep a seal around him as you suck him into your mouth and start to massage him with your tongue. Kris lets out a throaty moan. "Yes... That's good Casey, just like that. Seems that my master actually enjoys being commanded more than doing the commanding."

You want to question his words, but you feel that now is not the time for it. As you bob your head up and down his cock, his precum starts to dribble into your mouth. And the taste of it makes you moan around him, which in turn pleases him with the vibrations and makes Kris produce more precum for you to drink.

The concentrated aphrodisiac in his precum is incomparable to the amount that he fed you in his kisses. You feel the haze of lust clouding your mind, and you start to hungrily suck with increasing enthusiasm as you taste more of his precum.

Sweet. Intoxicating. A flavor that, you somehow know, is far more addicting and pleasant than a normal human's.

"I'm going to cum Casey..!" His grip on your hair tightens as he squeezes his eyes shut. "I'm going to cum. You better drink every drop of it!!"

And with a roar, he explodes in your mouth. The demon's cum actually makes you moan and rub your legs together in pleasure as you drink his thick seed. First a steady stream, them short bursts of cum continue to come out into your mouth and you greedily continue to swallow it all down.

However, your inexperience shows as you fail to keep a tight seal with your lips around his cock. Some of it is leaking out of the corners of your mouth and dribbles down your chin. Still, you gulp most of it down. Just as you begin to fear running out of breath, he stops releasing into your mouth and you release his cock.

Your jaw is a bit sore, and you are panting from arousal as well as having to hold your breath during his long orgasm. But you barely notice all that. Your entire body is burning with need.

Kris is calming his own breathing and pushes his sweat-slicked hair back as he looks at you with a satisfied grin. "That was excellent... You would likely be able to fool any human into thinking that you are heavily experienced with sex. However, I see that you've dropped some of my seed. I will have to punish you for that."
