She could tell that her Master cared about her. He wanted her to be comfortable with everything He had her to do. That is why she quickly began to trust Him, and does not hesitate to confide in Him. He knew that before she met Him, she had never engaged in anything serious related with BDSM. Indeed, until then, she had lived with her parents her whole life, and had to do with what she had. And quietly. So, He decided to take her training in charge. And He took it very seriously. She had told Him that she had never had any anal or oral sex, and that she did not feel ready to do it yet. A few days later, a big box came with the mail. On one side, she could see a woman on the strangest piece of furniture she had never seen. The woman had her wrists and ankles cuffed to the device. She was laying on her stomach. On the front, a dildo was in her mouth, so deep you could not see it anymore. And on the other end, another dildo seemed to stretch her ass rather painfully. Her Master smiled at her and she immediately understood that she was going to take the woman’s place very soon. But before, He read the description: ‘This is the most useful tool you will ever buy for your slaves, male or female. The dildos on each end are adjustable to truly split them. One is small enough to be able to breathe around it or fit comfortably in their ass. The other one will stretch them painfully. It is designed like that to have a choice: stretch their throat or hold off and have their ass stretched. The minimum length for both dildos is 5 inches. The bigger one can be as big as 12 inches long and 6 inches wide, while the smaller can extend to 12 inches long but only remains 2 inches wide.’ He did not ask if she was ready, she had no choice when it came to training and her dripping wet cunt clearly indicated she was already dreaming of being tied to the tool. Her Master set the small dildo for her mouth, 12 inches long, telling her she would stay here until she had had it ALL in her mouth for 24 hours non-stop. Then, he set the other dildo in her ass. At the beginning it was only 5 by 2 inches. She felt full but it was still rather comfortable. But every 15 minutes, He came, and enlarged the last dildo by one inch both long and large. She did her best but one hour later, the dildo was in her throat by 4 inches only. She really had no previous experience. Two hours later, the dildo in her ass was its maximum size but the one in her throat was still mostly out. Her Master decided to speed things up. ‘If you can’t take at least 10 inches of it in the next ten minutes, I will make the big one vibrate. Your ass is so stretched I wasn’t going to use this option but you let me no choice here.’ For the next minutes, as she struggled to force more and more of the dildo in her throat, as she gagged on it and threw up because it was too deep for her, she knew what caused the look of pain on the face of the woman on the box. It was none of the dildo. It was the fear. Fear that her Master would actually make the other dildo vibrate. She knew she could not take it. But mostly, it was the fear that she would not be able to satisfy Him, and that He would be disappointed in her.
