When you get done fucking your bitch you wait till she passes out. Once she is asleep you beat off on her back and put the sheets on her back. Put a lighter under a fire alarm and watch your girl run around screaming looking like superman.

To Superman that hoe is the action of hitting a girl from behind, a.k.a. doggie style, and to put so much thrust into it so that she cannot help bout sprawl out or lie down on the bed as you continue you to hit it. because you are doing such a good job she will be horizontal to the matress or floor with her arms outspread like superman.

A male cums on some hoes back & when the said subject lays back,the sheets stick to her back therefore doubling as a cape.
