I have been a slave for a very long time. At first I didn't want to, but now it is a way of life for me. It happened a few months ago, my mistress (damn she was hot) and I had just woken up. I was naked on my knees and my mistress was packing a bag. She turned to me and asked me to lick her pussy, I moved closer and buried my head in her pussy, after a while she pushed me away and said we were going out and she wanted me to drink about 5 liters of liquid before we left. Meanwhile my mistress got ready and waited for me to finish. My stomach was slightly distended and I had to pee already. My mistress picked up a large dildo and inserted it so that it was completely inside my pussy and made sure that it was fully inserted. Then she brought some more water from the kitchen and ordered me to drink it. Then she bent me over and put a dildo in my asshole and taped my holes together. I looked like I was a couple months pregnant lol. I put on a pair of slippers, a very short skirt and a t-shirt. Then we went out and stopped by my mistress's friends, I couldn't take it anymore, I had to pee I begged my mistress and she said she would agree on one condition: we would go into an outside restroom and she would put a dildo in my mouth and tape my mouth shut. I agreed and she took me to an extremely dirty restroom where she was sure no one would come. She had a dildo in her pussy and she took it out and put it in my mouth and taped it shut. Then we went into the toilet cubicle, my mistress took off her underwear and threw it in the toilet bowl and she peed first. Then she took the tights and t-shirt she had brought for me out of the bag she had prepared and threw them into the toilet bowl. Then she got close to my ear and told me that if I wanted to pee, I would pee on my clothes and then put them on. I sat on the toilet and my mistress gave me a good punch in the stomach. Nothing happened because the tape was intact. My mistress realized this and warned me that if I peed on her hand something very bad would happen to me and she took the tape off. Then she punched me again and the dildo squirted out and I started to pee. Just as I was relaxing, I remembered what I was about to experience and my mistress pulled out a dildo bigger than she had ever put in my pussy or ass before and waited patiently for me to finish peeing. After I finished, she gave me two options, one was to stick my head in the toilet bowl in that filthy toilet and the other was to use the dildo on me, which was sure to cause me pain.
