Quick or slow?

Cindy looks up at you to see your expression. "That's it my little girl.", you say to her. "Now run your tongue over its head and then put your lips over it" you command.

Cindy follows your instructions like an expert. She purses her lips and slowly takes the head of your cock into her mouth. "Take your tongue, and run it up and down my shaft, and then put it back in your mouth."

Her tongue lightly touches your erect shaft as she moves it down and then back up your penis. Again she puts her lips around the head of your erection and stops, waiting for her next command.

Your cock excitedly jerks, and you tell her "Take my cock all the way into your mouth. Continue to move your mouth up and down it. That's it. Slow at first, and then speed it up. Keep your lips tight around it."

"Gawd", you think to yourself as she follows every direction perfectly. Her mouth is so tight. "She must have practiced this before!"

And with continued ease she sucks your cock like a pro.
