Going to the loo

Mistress is very kind to me
She lets me ask Her for permission to go to the loo
She lets me go to the loo when i ask Her for permission
If we are out i have to wait till She or or others have finished
talking to ask Her quietly
I must ask Her in front of anyone present
Its humiliating to ask in public
I like asking Your permission for something so intimate Mistress
Thank You Mistress
