i have to pee soooo bad!

i always hold it in whan i'm masterbating... sometimes i pee on myself right when i cum

 one time i was so worked up i decided to go outside and get on a bus when i had to pee terribly. i had been playing with myself furiously, and i didn't even wash my hands... i smelled like pussy, and i didn't brush my hair either, i just stood up like a robot and walked outside and sat at a bus stop trying not to pee, and then the bus came and i got on. the end of the story is yes, i peed all over myself on the bus. i can still feel the sting of the humiliation! i got off through the back door, and i found a sort of an alley,  but it wasn't fully hidden from the street, and i squatted down and just swatted my bare pussy with my hand until i exploded!
