I was so desperate to pee that I walked in without checking if the bathroom was occupied first. I quickly stepped back out when I realised that Mommy was on the toilet. Standing outside of the door I let her know how desperate I was, after checking that I definitely couldn’t wait she invited me in. My little pee pee got so hard seeing her naked, seeing her vagina for the first time. She bent over spreading herself out asking me to stick my little pee pee inside her and release my piss inside her hairy pussy. (mommy / baby / daddy, pee pee words used)
