Sideways Hitler
When in a three way, the female is placed up against a wall with one man both fingering her and holding up her leg in a Nazi salute position while she paints a Hitler moustache on her face with the other man's penis. For this to work the woman must first dip the mans penis in some sort of ink or other fluid.
Me and my friend were bored so we gave his girlfriend the best sideways hitler she had ever had.
