Tilt your head back and open your mouth wide. With your free hand, begin jerking your cock, but be careful not to cum. Stick your tongue out to accept the dildo.
Slowly move the dildo towards your tongue, but keep them just a little apart. Stretch your tongue in a bid to taste your ass juices. Finally, get that tongue on that dildo and begin licking the tip, but don't push it in your mouth.
