ab-075 The lost bet (1)

Silvia made a bet with her friend. He promised her to buy her an expensive diamond ring in case that he will lose the bet. As she has no money to make him an expensive present she offered him to be his slave for 24 hours. Unfortunately, she lost the bet and today she wants to redeem the bet from him.
The problem is that his and her imagination of being slave are quite different: she thinks herself to be some kind of maid which has to keep the house. In contrast to her imagination he wants her to be a slave.
As she enters the room where all cuffs, chains and collars are she realizes what he wants her to be. Despite this she signs the contract which makes her a slave for the next 24 hours.
Now he puts her the collar, handcuffs and foot chains on which are combined with a heavy iron chain. This chain is connected to the heating so that she can only move some metres. Leaving the room her friend wishes her a lot of fun. Silvia has no chance to escape.
Two hours later he comes back. He tells her that he has to go to work again and orders her to go into a cage. He connects the collar she wears with the upper part of the cage and her handcuffs with the lower one. Then he closes the cage and leaves the room. The key lies on the floor outside the cage but she cannot reach it. Exhausted as she is she gives up.
Some hours later in the evening her friend wakes her up. He takes the Fiddle and puts it on Silvia so that she is not able to move anymore. Her friend leaves the room in order to go to bed. 

The next morning he enters the room again and notices that she looks like a baby. Silvia wants to know how long she will still be his slave but he does not tell her that. Knowing that she really likes to have the diamond ring he offers her a second chance. He suggests that this time it shall not be a bet to get the ring but her capabilities will decide whether she will get it or not. "The same procedure,” he says, "if you don"t succeed in doing what I thought up you will be a slave for another day.”
Silvia does not know how to decide: on the one hand there is the beautiful ring and on the other the fact to be a slave for another day. Finally, she agrees to be his slave again. Her friend thought up the following: he puts on Silvia five different kinds of handcuffs one after the other and she has to try to free herself with the key. Additionally, she gets a blindfold and a ball gag preventing her from using the mouth. The game begins and she can manage it to free herself as far as four kinds of handcuffs are concerned. However, she fails with the last pair. Consequentially, the next 24 hours as slave begin...
