In Monterrey, it's all about the 'nalgonas' at this explosive Expo. These voluptuous women, known as 'chichonas,' take center stage, their massive, bare behinds swaying to the rhythm of the music. Body paint highlights their every curve, making the dance an erotic spectacle. The crowd is electrified, their eyes glued to the sensuous display, as the women grind and gyrate, their bodies pressed together in a symphony of flesh and desire.
