Building up to Big Black Cock

Natalie has REALLY been wanting to stretch out her hold and train it for real big black cock, but she is so tight back there that she thinks it will take a little practice! She has to go from size-to-size using ALLLL the Dildos that she owns to loosen herself up enough for the big black one at the very end! She starts off with a little dildo, then a big white cock, a big brown cock, and finally that big black cock that just splits open her little sluthole! Do you think she is ready for the real thing? Or does Natalie need a little more practice?
