Well I have tons of fetishes but omorashi is my number one
oo i only have this fetish luckily but cant seem to satisfy it...
It's still possible! Boys don't pee EVERYWHERE. There are still places a girl probably wouldn't want to pee, even if she can do it standing up, like in public places. And not all girls know how to pee standing 
Yea that's great i love girl when they need to pee so so so much...
