I like white ones.............any ones in fact so long as they are clean
Every now and then I come across a black one and they are my favourite if im honest.
I prefer them when draped with a sexy little thong or G string though
Sometimes you lick them and there is not much happening , but other times I have heard a little noise/gurgling and Ive learned how to let off some of the steam or pressure that seems to have built up
