Despite their overwhelming cuteness, ducks are some of the most violently horny creatures I have ever had the pleasure (or displeasure) of observing. Usually when one male duck, mounts a female other male ducks get really excited, and attempt to join in on the mounting. Usually this leads to somthing of a really brutal chain-gang-bang. Also, the fact that the male duck will usually bite the head of the female being mounted, makes their mating ritual seem even more brutal. And sometimes, the majority of all this happens in the water, while the female is swimming nonetheless.
