Little Girls Talking Dirty(1985)

Christina DeLongpre owns and operates Fingertalking, where she pulsatingly performs the fine art of telephone-sex to absolute perfection. But warm and wet word-of-mouth appears to have gotten out of hand. This has resulted in an increase in the volume of Christina's business to the point where she is forced to hire additional help. Rising to the oral occasion are an erotic trio of talented talkers named Lisa, Tina and Claire. During an in-depth interview, Christina advises the girls that their best routine is to picture themselves actually living out the sexual situation that they are describing. As the girls go deep dialing on their own, each of them ends up in a steamy situation that explicitly proves that the next best thing to one's fist is the telephone!
