Peeing in roommates Juice & Laundry

Waking up a little hungover I'm in desperate need of a glass of juice so go to the kitchen, I cant believe it, my roommate has once again taken half my juice, how many times do I need to tell her. At the moment I realise how badly I need to pee and find the perfect opportunity to teach her a lesson, I take my panties off and empty my bladder into the jug before putting it back into the fridge. Later that day I walk around and her dirty laundry is everywhere, as I pick it up, very annoyed, I'm very grateful I've been keeping hydrated all day. I pile the laundry on the floor, spread my legs over it and pee all over it and walk off.
