In a special forum Stefanie meets Mistress Sandra, who is searching for a new slave girl for her rubber institute. Stefanie realizes that this is a big chance to let her rubber dreams come true. She must give up her former life immediately and has to start with an education, which takes a minimum of 3 years. Bald-headed and with a very restrictive contract, which makes her the property of the mistress, she starts with the education ... Punishment enema, fucking machines, heavy hood training - and always dressed completely in rubber. This is now Stefanie's new life.
