Every good boy MUST be trained to take real cock. I mean, what could possibly be hotter? And not just any cock, but a huge cock that will fill his holes. I begin by stretching his ass with an anal trainer. Once he is gaping, nice and wide open, he earns the title "butt slut" that I write on his ass with lipstick. To complete this training session, I allow him to cum but only while sucking a huge strap-on.
