There must still be some cum stuck inside your asshole. Reach in deep with your finger and try to pull the remaining cum from your hole. Reach into every corner of your asshole to get the last remaining drops of that savory cum.
Once you think you have all of the cum out, take that finger and suck all of the cum and ass juice from it. Savor that unique mixture that only a few whores have tasted before.
Now, kneel down before that pool of your own cum and ass juices on the floor, put your hands behind your back and then lean over and proceed to lick up all of those juices. Use your tongue to clean every last drop of the cum that you just shit out of your ass onto the floor.
Can you taste the pure humiliation of performing such a taboo and degrading act?
