Here are the various levels of what i personally enjoy getting from highest to lowest:
1. BBBJ NQNS - Bonus if the lady just absolutely loves doing it and you can TELL that she does.
2. BBBJ NQBS - As others have said... if you're a spitter, it's hotter if you let it dribble out of your mouth, onto the dick again, etc.. play around with it like a dirty girl.
3. BBBJ COF, COT - If she won't allow CIM, then these are the best scenarios
4. BBBJ which is part of the apetizer, then on to CFS
5. BBBJ w/ HJ finish - it's ok
6. CBJ -
You might as well clear about 10 hours of your schedule, because with the reduced sensitivity it will take forever via a covered BJ.
So do the various levels make a difference? Sure they do. If I read a review where the lady was enthusiastic about sucking dick and loves CIM, then she immediately goes onto the "would like to do" list.
So for any ladies reading this that really enjoy the BBBJ CIM, especially NQNS, feel free to pm me and let me know so I can find out just how much you enjoy it. hehe
