Lucia has been out on her bike in a very skimpy outfit and comes home. She seems to have had a problem and starts checking the bike over in the kitchen even though she's desperate to pee. This leads to her pulling her panties to one side and peeing on the floor. But part way through she hears a knock at the door and goes to answer it, there's nobody there. She comes back to inspect the bike thinking that having pissed a bit she'll be OK. That is correct correct though and she ends up pissing the rest onto the floor through her panties.
