Getting it on with a always live phone sex girl is an invigorating experience. Of course you would want to choose a sexy girl who is allowed to speak uncensored and with no filters. Also you are looking for a chat service that offers affordable rates and set blocks of time.
There are many places you can find such services that are affordable, un filtered and with nasty girls who are eager to please. A simple search reveals many, but choose wisely since many venues are deceiving. I look for a service that allows the customer to purchase his or her time upfront.
Purchasing your time up front will help you avoid the money trap of a greedy girl who just wants to milk per minute charges out you. Kind of like a stripper hanging off a pole. In the end you wont be satisfied.
You may also want to select a chat line that has photos and un edited biographies of the girl you wish to talk to. Her particular likes, dislikes and what gets her off are things you can look for. You would be surprised how many men and women do this because they are over sexed and under satisfied.
I recommend the following link because they are honest and offer live phone sex.
