An idea of a task, would be while you are out for dinner, you will drink plenty of water. You shouldn't be thinking about peeing until get back to your dorm.

While you are out, you still need to use the public bathroom. In the stall, with a full bladder, you will strip naked and sit on the toilet with your legs open wide. But instead of peeing in the toilet, you will watch some desperate girl peeing porn video. You should edge to the video while watching this. Should be a plus if the girl in video get to cum and pee in the end while you get nothing.

When you put clothes back on, you should wear one piece less then you started. Pantie is the best option, but a sock is acceptable

Some option to make things worse.
1. leave the door unlocked.
2. play the porn, the pissing part, without using headphones.
