If you want a higher chance of DFK - go see an SP. Semi-legit and even holistic nowadays is very much YMMV.
Of the semi-legit Iโve only had one give me DFK. Of the holistic, Iโve only had two give me DFK. Other girls will SPECIFICALLY say kiss but no tongue or just turn so you get their cheek.
Could a better tip help? I suppose, but from the ladies Iโve seen, itโs easier to get CFS, CBJ, and even BBBJ sometimes more than DFK.
