You're never going to be man enough to fuck me, but I can find another way to make you useful - I'll turn you into my fluffer! In fact, I want to get you completely addicted to sucking dick.
I'm going to train your cock to get harder and harder while you have another man's dick in your mouth, mind fucking you into becoming bi. Stroke your dick like a good boy while I make you deepthroat his cock - I want you to be my perfect fluffer slave.
You know I shouldn't have to suck his dick myself! I want you to do all of the work for me. I deserve to relax and be entertained with your deepthroating attempts while I wait for his cock to be ready for me to enjoy.
The only way I'm letting you cum today is with his dick down your throat. Keep sucking his cock and jerking yours until you explode for me with his cock in your mouth. You'll be craving cock again soon, and I'll be happy to use you as my fluffer bitch.
