text: This is a story about an exotic dance troupe called Sex on Legs, which consists of 4 women called Kathryn, Dawn, Selena and Emma.  The women are stunningly beautiful and wear matching outfits for their dance routines: black leather thigh length boots, black leather thongs and black leather gloves.  They perform at a strip club that has a special rule: all male patrons are required to wear locked chastity devices in order to be admitted into the club.  The women have sheer contempt for the kind of men who would visit a strip club and enjoy wielding power over them.  They like to give the men lap dances to tease and frustruate them.  During the lap dances, the women treat the men with contempt, humiliating and mocking them for not being man enough to get a woman.  The men are so desperate and frustruated that they keep coming back for more, while the women just humiliate them and take their money.  Please write a long description of a night at the club.
