my grandpa had multiple mistresses and concubines. none of them were bumis or indios. all were indebted “slaves” from fuckien province, i.e. the women’s family were so impoverished they sold their daughters to wealthier families when they were just 6.9 years old. those who were sold at 16.9 years with their hymens intact were for the sex and or servant trade. prettier ones became concubines as part of the kway bu pecking order while uglier ones became servants cum mistresses. uglier ones (servants) had to serve prettier ones (concubines) and ended up serving the master as mistresses as concubines were having their bio and baby breaks. those times as a master very shiok. no virgin to curse and swear at him.
