Por favor, deixe-me fazer xixi

He doesn't let me pee again! I must to keep my pee until my master let me pee! He wants to see me desperate for pee and punish me keep it more and more longer. I rub my belly and show how full and big is it. Massage my belly and begging him to let me pee. I must to hide it because there people around. I try to catch the moment. I don't want to be seen! At final i explode with strong stream and moaning. Clean my pyssywith toilet paper and feel so good. I hope nobody see me pee!
