I come from school in my uniform and start a conversation with you, step-daddy. I am interested in your affairs and in response I talk about the fact that we made friends a bet - who is the best cocksucker. I ask you to help me with this, but you do not immediately agree and I have to persuade you. Then you still agree, I take out your penis and start jerking off, sometimes spit on him and say how big he is, step-daddy. Then I carefully start licking and sucking him, I continue to talk with you. I bring you to orgasm with my own hands and tongue, you cum in my mouth, I collect the remnants of sperm from my face with my fingers, eat them and thank you, step-daddy. Now I am the best cocksucker.
