Give that cock a little kiss and go to the nearest wall. Lay on your back and then swing your legs over your head. After you get in a position where your cock is dangling just in front of your face, let that cock enter your ass again. Let it begin pounding your ass just like before, only this time, make sure that it is hitting your prostate.
It's time for yet another humiliation action that only true sluts can ever know, the assgasm. That right slut, you are going to come directly in your own face without your hands or mouth touching your cock. Let that cock that is fucking your ass generate your cum for you.
Keep getting fucked until you feel a strange sensation building up in your cock, almost as if you have to pee. Don't let the fucking stop when this sensation builds, simply let the hot cum flow out of your cock and onto your face. It you want, go ahead and open your mouth to let some flow into your mouth.
Look at you, you just gave yourself a hands-free facial. The best thing about an assgasm is that you can still have more orgasms right away.
