Whan having a full bladder just isn't enough. Last time I did this with water and now with air! Inflting my bladder to its maximum has become a part of my life now. I love the intense feelings from the extreme pressure and clenching my muscles to keep it all inside. It's even better when I can use ma endoscope to taake a good look inside and watch my stretechd out walls. Doing this with water is already amazing but doing it with air is a completely different story. This is how it went: My bladder is already filled with more than 1 liter when I'm pushing the cam inside my pee hole. It's difficult to relax to let it slide inside while trying not to leak too much. What makes it more difficult this time is that there is already a tube inside that reaches all the way into my bladder. This time that tube is connected to a balloon pump. My intentions are clear. After taking a good look around inside, I aim the camera at the end of the tube and start pumping. On my screen I can watch live as the bubbles come out of the tube and start connecting at the top of my bladder. I can immediately feel the increase in pressure and it makes my sphincter muscles twitch. They want to let go! I keep pumping more and more air inside, allowing myself to slowly release the water while keeping the pressure at a maximum. I can feel it and see on my screen how the air slowly replaces all the liquid inside. It's fascinating! After a while, all the water has been replaced and air starts leaking with a farting noise. It tickles my pee hole and causes me to clench it hard, sending a shiver of pleasure up my spine. I look at my scrren. So that's how a bladder looks inside when there's no pee. Interesting! I'm taking my time to enjoy the feeling, squeezing and puching the firm bulge on my bally. Then I unplug the pump to release the air. Slowly, my bladder contracts and pushes all the air back through the tube where it entered. I watch ********** as my walls contract. The moist wrinkles that form reflect the light of my camera and make beutiful patterns. Finally, my bladder is empty and I exhale in relief. My heart is racing. I look down on myself and all the water that soaked my towel. I can't believe all of that was inside just a moment agao. I definitely have to do this again!
