Sometimes I pound off upside down with my back against the side of the bed, my head pushed against the floor (face up), and my feet on the wall. I do this so I can blow my load all over my face and in my mouth. It is hard to orgasm with your own penis pointed directly at your face. But if you can pull it off it is exhilarating. You get this feeling like "I can't turn back now, better close my eyes and swallow fast!"
