Sentado no louco balão de 1700 ml de urina com enorme gozada

Insane bladder training to break all my limits today. After taking 700 ml and 900 ml balloons I wanted to know how far I can really go. The 1700 ml were obviously not going to fit but I wanted to feel more pressure inside me than ever before. So when I reached my limit, I just sat down on the balloon! It was absolutely impossible to hold in the presure and it started splashing out in a fountain. But that just turned me on so much I couldn't stop so I kept squeezing the balloon and even pushed it inside my tight ass! It was one of the best feelings I ever had when I was finally able to cum in the end.
