在我出去之前清理我的屁股（屁股崇拜）

I'm going out and I need my ass cleaned before I go.. So that's your job, to make sure my asshole is fresh and clean.. Do not leave anything behind, and I better not see anything when I wipe. That's what an ass slave is for, to use your tongue on my ass.. I might not shower for a few more days, just so you can clean me again.
