Mary needs to cook something. She starts by warming the water but soon she feels the need to urinate. She cannot leave the kitchen wile the water is boiling so she grabs a casserole and pee in it. After the water has boiled she goes to the bathroom and empties the full casserole in the toilet and then she goes back to the kitchen. No need to waste such a good casserole. She had a lot of pee in her and she feels good now although some of it dropped on the floor and she has to clean it now. She is just relaxing on a couch and enjoying her coffee. Soon she feels her tummy aching and her bladder ready to burst. She rises on her feet, opens them and pee in a empty food wrapping casserole. Then she goes to the bathroom, pours it in the WC and washes it so she can pee in the casserole again next time.
