Hmm.. Hello Ratchanee,
Here is my picture... :) :0
I am imagining you on your knees and I am standing in front of you. You take my cock in your mouth and I slowly move my cock in and out of your mouth so softly and slowly..... After some time, I become excited and thrust harder into your mouth, sometimes putting my hands on the back of your head to gently push you deeply onto my cock. It is then that I cannot stand it any longer and shoot my cum into the back of your mouth.... Like a good girl, you swallow everything and show me your clean mouth...
