The beauty of having two 'toys' is that when you're done with one, you can swap it for another. That is exactly what Charlie does with her toys, when she's had her devious way with one, she simply swaps it for the other. Once Danni has had her fun, she's returned to the 'storage room' and replaced with Brianna, who is released from her handcuffs, led into the bedroom and laid on the bed, for Mistress Charlie to do her worst.
