The more you see them the better they do for you
I been seeing some for years and they know how my cum taste and they tell me if its sweet or sour on that day and tell me if how they want to get it. The bottom line is that if you have some regulars, train them well and they will enjoy with you. Not all will accept this so be careful who you choose cuz then they gonna try to control you. We should neva let them control us cuz we da customers period! Unless they start to give it free then let them have their way sometimes. if you see one outside and she lets you have for free then you know you got da ins, but be careful cuz they still want something.
When it comes to AMP chicks, always sleep with one eye open and one hand on your balls and da other one on your wallet.
