I am in white cotton panties. Full bladder makes me so horny! I fill my bladder up even more. I start to masturbate with the Hitachi wand over my panties. I talk about how horny I am when I have to pee. I love it, I love having wet panties too! It starts to get too hard to hold, I can feel myself absolutely bursting. I talk about how much I have to pee. I let out just a few drops. I do this a few times, but around the third or forth time I can't stop the flow. I fill my white panties with pee, and then continue to masturbate with my wet panties until I finally have an orgasm.
