In the Star Wars novels there is a charactor named Mara Jade and she was originaly an assasin of the emporers sent to kill Luke skywalker and even after the emporor was killed she kept trying to kill him but they eventualy became unwilling allies and then friends and then married. But sometimes i would think about when they were unwilling allies and they would get into fights (ie lightsaber sparing) and I would think about how it would be kinda cool if during one fo the fights MAra just look luke down and they had what one fo my friends terms "angry sex".
