That was a walk of shame if I have ever seen one!
Now, I want you to bend over and reach back and pull just one of those sharpies out of your hole. Once you have it in your hand, I want you to suck it clean. Don't just a quick blowjob, but really vacuum your ass juices off of that cock.
Once it is clean, slide it back into your ass and slide another sharpie out. Proceed to suck your ass juices off of that one as well. In fact, I want you to do the same for each of the four sharpies that are rammed into your ass. After all, that walking must have really allowed those sharpies to move around into different corners of your ass.
That's is slut, enjoy the taste of your own ass!
