A good slave must be able to forget about his masculine pride in order to better serve a Woman. I found that a good way to train a male in this direction is by making him eat his own cum.
Eating your own cum is something that you'd be tempted to try, isn't it? I know you want to, it's always on you mind when you jerk off, but as soon as you cum and are not aroused any more - it just becomes too difficult, too disgusting.
Today you are going to go the whole way. Your going to cum AND your going to eat every single drop. How many times have you got right to the point of taste your own cum and pussied out?
Being the loser that you are you know that eating your own cum is something you must do. The privilege of being able to orgasm comes at a cost and that is one humiliating gulp of your own hot,salty semen. I enjoy the humiliating feeling you go through every single time.
