Trained To Be Your Girlfriend's Slave
Don't worry he hasn't taken her anal virginity yet. At the moment he is satisfied with daily blowjobs and raunchy sex.
Again I want you to look at the cock for another 2 minutes. If you stare at her for a second during that period I want you to slap yourself in the balls. That is not allowed!
You will have to get used to seeing cocks from now on. It will be a severe punishable offense to stare at any female sexually and you must always worship his cock. His cock is what makes him great, strong and sexy. Why shouldn't you worship it?
Stare at it now, think about worshiping it. You are enjoying it aren't you? I knew you would eventually like the idea of eyeing up his massive cumshooter, I bet you are now jealous that she gets to fuck him and you don't.
