my step-brother wouldn't leave the bathroom and made me pee myself :( I seriously tried to hold it in but i had to go so bad and he just stood there watching me squirm until my bladder just gave out. my warm piss gushed out into my underwear and leaked all over my jeans. it started off humiliating but it honestly ended up being so much fun giving into his game. i just kept letting him watch me for the rest of the day and... eventually let him use me as the toilet.
