Two incredibly sexy female warriors were defending a fort, one was armed with a sword and the other with a spear. One of them takes a look and saw that they were being surrounded. The other girl suggested that they should just kill themselves rather than be captured. She agreed. The girls then stabbed each other in the navel, one with a sword and the other with a spear. Predictably, those tough female warriors took a very long time to die.
