Well, I'm a tough customer when it comes to BJ and have rarely found a lady that can finish me off with one since I need a whole lot of friction, so to me the best ones are the ones with lots of friction...

MsMiaBbw, has this great technique that is hard to explain but it's got lots of friction...so much so that she can get me to start shaking involuntarily and gets me that point of ecstasy that I'm about to loose my load but I have yet to actually finish. But gawd it feels good to get worked over in that way...
But that's my opinion...
Mia, I know I owe you a review, but I may have to go back for a refresher course just to make sure I have the details correct
