Jerked Into Your Waiting Mouth

I have my slave restrained in a humiliating position, legs spread and his cock dangling over his mouth. I explain that I'll be forcing him to eat his own cum and he can't do anything about it. At the first touch of my fingers, he's already beginning to pant. I stroke him as I stare into his face, the same face that will soon be covered in his own jizz. Soon he's twitching and spasming as I jerk him right into his own mouth.
