I have had some awesome phone sex in my time. A lot depends on the voice on the other end, but I've had some great orgasm's while doing it. It's great to hear the sound of a wet pussy and hear a girl moaning louder and louder until they cum. I've talked to one girl who had a dildo and she would put it in herself as if it were me. I told her to put it in her ass and I could hear her going crazy and getting louder as she slid it in... she was screaming when she came! It was awesome! Definitely worthwhile...
