I know you want me bad but you can't have me. What you can do is stroke your dick for me but at a price, if you want to be allowed to cum. I have a little surprise at the end for you but for now, slide your hand down your pants and start tugging on that cock for me.
I want you to pull out your dick for me and stroke it. I'll let you cum but only if you follow my instructions like a good boy. How could you possibly resist?
That's right, I want to see you lick that cum up like a good little cum eater! Haha, every last drop.
