According to the reference volume "Sex and the
Single Smurfette": as a form of group sex, a Smurf orgy becomes inevitably a gangbang due to lopsided demographics. In the Smurf village there is only one Smurfette. There are seemingly unlimited numbers of male Smurfs, each of whom has blue balls. The only way to relieve all of these blue balls is for Smurfette to
smurf every man or boy in the village, one by one, until everyone's smurfed out and too
tired to continue.
