No question roomie, you were making a great effort, and I am sure eventually you would have been able to get it all in your throat.  Its just a matter of learning to breathe, focus and controlling your gag reflex. But as much as you were trying, I think its time for me to take over.  Flip on your back, so I can help you out. In this position I can shortcut the learning process.  

This will be slightly different, before, I was letting you suck my cock.  It was a gentle way of letting you come to grips with you new role in this apartment as cum dump.  I was trying to be nice, since we live together.  Now, however, I am going to show you who is in charge and what your new role really means.  With your hands duct taped by your sides and your head in this position, you will be unable to resist anything I ant to do to you.  I am going to skull fuck you hard. My cock will force its way deep into your throat and stretch it out.  You won’t be able to talk above a whisper for at least a week, due to the friction burns.  Your gag reflex will be obliterated.  As my cock punches in and out of your face, you will learn that you are nothing more than a hole for me to use for my pleasure. We will do this procedure over and over until your mouth is fully transformed into a cunt for my cock. I am usually good for three or four loads in a row, if it takes more than that to train you, I can call some of my friends over to help.

Now take a deep breath and we can get started.
