I like watching you put thing in your ass, but I want you to cum like that. I don't just want you to cum with something in your ass, I want you to cum from fucking your ass alone. I want you to be so trained on My cock that you can't cum any other way. I want your ass to be so used to My cock that you beg for it, because it's the only way you know how to cum. My average cock is so much bigger than yours, which is part of the fun of it. My dick is average, and it's still ten times the size of yours. So, why wouldn't you use it? Why wouldn't you want to cum on it? I want you to cum with My cock, so do it.
