Scenario: Cold ice sucking

Drink at least 1 liter of water before we start this one. Maybe you will get lucky and it won't be an issue.

Fill three bowls with cold water, and float at least 6 ice-cubes in each bowl. Place the bowls in a triangle on a table. Insert a butt plug (size is up to you, but bigger is better) Wait 15 minutes before starting.

Can you bind your hands behind your back? I hope so, you sound very creative. Or do whatever you can do to make sure you can't use your hands for this challenge.

Bending over the table so that each breast is in a bowl of water, you need to pick up the iceblocks from the third bowl in your mouth, and swallow them. You can stand up to swallow, but until you have a block in your mouth you need to keep bending over with your breasts in the other bowls.

As soon as you have swallowed all the ice, then you need to bend over and drink all the water from the one bowl.

I hope that the water you drank and the butt plug didn't make you need the toilet too badly, because you need to finish the whole task before you can relieve yourself.
