Nine lingerie-company employees celebrate their annual trip with a no-ranks drinking party where the president, managers, and office workers all cut loose. They recruit male hotel guests on the spot, turning the banquet hall and surrounding rooms into total sexual chaos. Once the orgy starts, nobody stops: bodies are pounded from every direction, and the women keep fucking and cumming long after everyone has lost count, revealing a side of their bottomless lust seen only once a year.
