Pencil dick- a funny story of today.

so I was having sex with this guy today and he is really confident about his dick. Well the thing is is that he is about average size (5.5-6 inches) and really thin, so he doesn't have much to be cocky about (no pun intended). Well, while I was blowing him,he goes "deep throat it baby" and I didn't know how else to tell him, so I look up at him straight in the eyes and go "It's already all in."
