Cleaned
It should go without saying that I expect my things to be clean at all times, inside and out. Its fuck-hole needs to be ready, willing and able at all times to take whatever I might decide to shove up there without making a mess. I enjoy administering enemas for another reason as well — so it knows that there is no part of it that can escape my control. Once I've taken its dignity, injecting ice cold water through its bowels will certainly give it a deep sense of being owned. Even better when it starts to cramp up and has to beg me for permission to crawl to the toilet to release.
