As i get to your panties, i start touching you, and you can see my cock hard as a rock on my jeans. You look with lust on it and i see your face, that reaction from you makes it even harder. Your lips look a little bit dry and i make you drink water

Btw, as I'm going down with the hand, i keep more time on purpose on your bladder pushing it in, in circles, up to down... whatever direction, but i make it with my fingertips and finish with my palm on your bladder teasing it and going down to your panties

I'd start a short interrogation about why you need to pee (time, drinks...) as i start touching you softly your nipples, going down slowly to your bladder bulge and push to make you moan and squirm in desperation as i ask you things, and finishing going softly until i get to ur cunt on the panties.

Dm me if you wanna do it, or if you wanna tell me how the challenge went

It's a very good story, i love the scenario and how you developed it until that perfect climax
