What is The Uncle Sam?
1.
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.
I was getting bored of just a regular blowjob so I gave my partner "The Uncle Sam."
