At some phonesex sites the operators are called Mistresses.
One caller may want a cuckold fantasy, another may want teasing and denial, another may want to talk about his life in panties etc...
Being able to play different characters (or in some cases multiple characters) makes it possible for them to deliver exactly what you are craving for.
As we previously mentioned nothing beats talking to a slutty chick and watching her doing the nasty, simultaneously.
Good phonesex babes can't wait to hear what their callers are yearning for.
Their minds start whirling on how best to make their clients' fantasies come to life and be as real as possible.
