"You're my slave, and i want you to say it out loud and understand that it's true.."
(You do as you're told)
"Good, I know that it makes your little cock throb, it's probably the hardest it's ever been. Well, if it wouldn't be just so small, you know?. I think most people would just laugh at it when they get to see it, it's really sad, but i bet you already know that.."
(You lower your head)
"Yeah, so you're lucky that you even get this, that i'm allowing you to look at my body because not every slave of mine gets the opprtunity to see me naked, or in lingerie.. Keep tugging, do it a little bit faster again, just a little my little cock slave, enjoy this beautiful view.."
(You stroke faster)
