Rubberbitch and her Master visit Berlin. Walking down the staircase they see how abandoned it looks. So they have an idea how to have fun. It is so exciting to find a place where you can let your small passion becomes a real desire. Dressed in latex, masked and trembling they starts their staircase games. Rubberbitch puts her Master's cock into her mouth and starts to suck it with all her love. It is her favourite work for her Master. She is really good in it. He can't stand and cums into her hungry mouth.
