...about his big dick. And watch her eyes light up.
I want you to verbally smother his cock in compliments. Can you do that?
Remember, you are her tiny dick sexless friend, while you sit there and praise it. And the best way to praise it, is to compare yourself to him. And make it sound jealous. I just want you to bear that in mind.
I want you to compliment and praise every detail you can think of about this cock to her.
Tell her how unfair you think it is. Tell her how much bigger it is that your cock.
