Duck Penis Followup

In my last post about the evolution of Sperm, I mentioned female ducks evolving to have complicated oviducts to thwart insemination from male ducks who rape them. Here are videos and a picture of the complex duck penis accompanied by further explanation of how duck sex goes down: http://blogs.discovermagazine.com/loom/2009/12/22/kinkiness-beyond-kinky/.

Hat tip to "Peebs" for sending me this.
