With cum and spermies in your mouth I'm assuming your holding your breath. Don't, just breath through your nose. you will need to learn this technique for deep throating anyway! get 5 good deep breaths through your nose. this gives the sperm plenty of time to swim around your teeth and gums and tounge.
once you have done this pull up your sissy picture and stare into your eyes as you take a gulp down of that warm cum!
