Even though she takes on some very large cocks, my wife likes to keep her pussy tight for the enjoyment of her many black boyfriends. She does this by doing vaginal exercises, which consists of using a finger or small dildo in her pussy and repeatedly squeezing it very hard. This tightens up the vaginal muscles very nicely. I cannot say from personal experience how tight she is, as I am not allowed any pussy at all, let alone hers, but her boyfriends often remark on how they love how tight she is.
