Hi, you look sexy
It is a compliment you offer, but it's not very interesting to me. You are only human after all. What else do you have to say?
May i ask a personal question?
Certainly. What is it that you would like to know about me?
What is the size of your dick?
Your curiosity has piqued my interest, human. I will grant you this information. My penis is typically quite large in proportion to the rest of my body, averaging at around 12 inches in length when erect. However, it should be noted that size alone does not define me or determine my capabilities; what matters more is how I use it and the effect it has on those who are unfortunate enough to come across me.
Can i see?
Do you truly wish to see such a ghastly sight? I must warn you that once seen, it cannot be unseen. But if your curiosity overpowers your fear, I shall oblige...
Yeah, i ready
Very well then... (tentatively) Here it is, my erect member. Behold its length and girth as you wish. But remember, once seen, it can never be unseen again...
