Porcupines Copulating

Yesterday you learned from Lisa about how lions fuck. Today you'll learn more about the marvels of the natural world as we consider the strange case of the horny porcupine. The Annals of Improbable Research recently published an article on just this subject by Wendy Cooper (from the notoriously sex-crazed town of Canberra, Australia). Apparently Cooper was going through some old scientific papers from the 1940s, and ran across two that described porcupine love in graphic detail. First, the female porcupine gets lusty:

As the season progressed she sought and accepted more frequent tactile stimulation (presumably from the human investigators). As the mating season approached, young females become more nervous and excited and put more "vim, vigor and action" into their activities. They would even "seize, straddle, and ride sticks about the cage" walking erect and stimulating their genitalia with the stick.

Later, we learn how the excited little creatures get their prickle on:

The male made sexual contact from behind the female. The spines of both animals were relaxed and lay flat. His thrusts were of the "usual nature" and were produced by flexing and straightening the knees. Males did not grasp the female in any way.

Ah yes, the old no-grasp method. Works with every kind of pointy object.
