Need urgent help with sister

I accidentally shoved her toothbrush up my anus in a fit of horniness.

What can I do to make sure she won't find out?  I already cleaned it enough that nothing is visible or smells, but what about taste... I don't feel tasting it would be a good idea, or would it?

But if she somehow finds out... I once found some handcuffs in one of her drawers, I suspect she will treat me roughly...
