When you are having sex doggy style with a woman who is rather short and you pick her up by her waist with one arm around her waist and continue to fuck her while her feet and arms are flopping around as you pound her out wildly
Did you see that short girl I got last night? I gorilla fucked the hell out of her.
After selecting prey, one mounts the victim in the doggy style position.. from here, almost instantly, one loses all human decency. The victim notices this because animal beast yells and ass grip come together as one. Ass pounding ensues (may or may not include donkey punches)
Do you remember the guy from last night? He gorilla fucked the shit out of me...
