Silverbacking 

Place the female into the missionary position. Then while standing on the balls of your feet and bending the knees; place both fists firmly above the females shoulders. You will respectively be in a Gorilla Like position. Next thrust erratically into the females vaginal area. Now, right become reaching climax you must stand straight up over the female. While ejaculating over the defenseless female one must pound both fists on his chest while roaring.

Once I bring that chick home I'm gonna be silverbacking her all night long.
