Derived from a common practice among German prostitutes. The customer pays for and expects to get a blow job. The whore goes down and rubs his dick on her face/neck and gives an occasional tug on the ol'tube-steak, but they never actually perform the blow job. Afterward, they not only take your money, but they say it'll be double for a real blowjob. Those blooding fucking German cunt ass whores!!!
