When you punch your partner in the nose, let it sit for a day or two so the face becomes black and blue (but we all know it's really just blue). Now that the bruise is fully colored, cum on your partner's face and punch him/her in the nose again, allowing a steady stream of blood to trickle down over the cum covered bruise. Thereby, beautifully making the colors of our American Flag.

The ultimate combo move. Instruct her to gargle blue Powerade when getting head than begin the procedure for a jelly doughnut. Make her laugh to create an angry dragon and finish by saluting and humming the star-spangled banner.
The uncle sam is my favourite patriotic theme sex move, even if it does turn her tongue blue.
