I'm assuming the duck's on top

Ducks are used to it, female ducks developed curled vaginal canals to deter forceful reproduction but male ducks simply evolved corkscrewed dicks so now ducks never reproduce without inflicting great agony.

I doubt the fascist pin pricks can hurt them.

Poor human. Those corkscrews are not to be fucked with.

Auto correct.

They meant to say suck a fuck, not fuck a duck.
