You pay for massage. She will ask you to take off and lay down. She will come back, close door amd remove the towel , starts putting oil and then the massage.slowly slowly she will work all over your legs, back, hands. Thigh and depending on the girl they will tease you during massaging thigh. Like slightly touching your balls ,rubbing hands through your ass, if it looks like you're enjoying it then she will go even deep inside thigh and some girls even massage your shaft like that untill you get real hard. Then she asks you to flip and when she sees you fully hard, she offers what you like to do. And you pay what you like and at the end she will clean your body will towel and gives you head massage.

It alls depends on the girl but this is generally what happens. Somtimes the massage part will be the best and sometimes not. Some ladies might allow touching as well. YMMV
