Finding the limit while playing on both holes! Do oyu know the feeling when you're so full and you're sure you can't take any more? Turns out there's always a way to go further: After all this baldder training I can now take 1,5 liters with no problem. The feeling makes my belly tingle and the urge to release it increases with every second. But I can hold it. I need to squeeze it even more. Pushing a balloon up my ass barely works and when I start pumping it, the intense pressure floods my body with hot and cold showers. The Balloon in my ass starts taking up more and more space s my bladder is pushed out even more. The bulge is huge! Pushing out the balloon almost makes me cum on the spot as I erupt with squirt. But I know I can take more. It's time to try this for the first time: Fisting with a full bladder! My ass is ready and my bladder feels like it wants to explode as I spread my ass. Going gentle will get me nowhere now. I know I have to go fast if I want to make it inside. I shove in my fist - and my body erupts in agony! I can feel the firm, round ball that squeezes my hand inside my ass: My Bladder! It's so big I can't even feel the upper portion of it, no matter how deep I push my hand. My whole body is burning. My belly looks like it wants to give birth, my ass is being rubbed from the inside and my dick is throbbing and leaking with every movement of my hand. The pressure is insane. Pain starts fusing with pleasure and makes my heart race. I can hear the pounding on my hed and feel the same beat shaking my whole body. Every push of my hand makes my brain melt, every pull is like a relief I've been longing for. I don't know how I managed not to cum but after a while my moves start getting slower. The pain fades and I realize I must have peed almost half of what was inside my bladder. I feel happy and relieved. Now I have to clean up :D
