Here is a dare for you if you can do it and if you have the time to do it.
First thing you need to do is give yourself an enema to clean yourself very well, do it a few times. Till water comes out clean..
Now the dare. I am sure you have a house or apartment that needs to get clean i sure parents would love it anyway. While you alone get the mop, broom and duster and put each in your ass, once in you will do that chore, so if duster in dust, if broom in sweep floor and if mop in mop the floor. If you can vacuum. You can use a condom or balloon to keep the product clean.
So you will be basically cleaning with your ass. This should lead to interesting things including training the grip of your ass.
If you can or cannot do it please tell, if you can only do your room that is ok as well
Good luck on said chores
