Pretend to be a bed-ridden hospital patient.

That means:
(1) When you need to pee, you must pretend to ring a bell and then wait a long time until you're almost bursting. Don't get up to use the toilet but pee into some sort of bed pan (use an old cooking put or bucket or something).
(2) Perform exams on your pussy. Use tools like spoons to pry it open (and a mirror to peek inside), or invade it with like a carrot. You can also perform such exams on your butthole.
(3) When you go to sleep, do so with an object in your pussy pretending you have to do a long-term exam through the night.
(4) On the next day, you cannot use the toilet in the morning. Instead, step into the shower and pee standing up, legs NOT spread apart, but let it run down your legs. That's your last task before the control of your pussy/bladder goes back into your own hands.
