Technically, what you are talking about would be rubbing vulvas together, since the vagina is inside. The vulva is the slit-shaped opening.
Inside the vulva, and just in front of the vagina, is the clitoris, a sensitive organ with many nerve endings. Rubbing the clitoris can give pleasure. This can happen when a woman has intercourse with a man, or if she masturbates by rubbing with her hand. Two women can also rub themselves together, pretty much as if one of them were a man (but neither would have a penis to put in the other's vagina).
