You gotta ave the right technique consisting of the right amount of fingers and motion speed..
But the real question is what is the right tekkers? Examples below..
I personally use The Rocker or The Showstopper
BBHOLLOGRAMZ goes for The Rocker too whiles Joey Da Kid uses The Pleaser technique (what a pussy)... no Pun intended..
Right amount of fingers + Motion + Correct Speed = "da bitch be cummin out of her ears!"
