The nights of the full moon have long been known to create strange behaviours from werwolves to irrational driving on highways.  A new behaviour to add to the list is the fact that Dir Town girls of Pakistan, find it irrestible not to have group sex with other Dir Town girls of Pakistan whenever there is a full moon.

According to Dr. Laminate Bifurcate, of the University of Bangle in Bengal:

"The moon produces a special chemical when it is full, which acts as an aphrodesiac on the girls of this particular place in Pakistan."

Dr. Bifurcate also said the girls were entirely helpless to stop themselves from meeting in a forest grove, and dis-robing.  They then have a full night of incredible sex with each other.

Dr. Laminate Bifurcate says he has witnessed this many times but is at a loss to really explain it scientifically, so he will go on witnessing it until he figures it out, which, according to Laminate, "could take years."

In the meantime the Dr. will study the moon more closely, and the girls more closely still. After all you can never have too much information.
