@ascribbler,
how is doing what comes naturally make me a pervert?
My situation is I had a large bed custom made to accommodate my 3 wives and myself and we sleep together. On a daily basis we enjoy sex together all 4 of us. Occasionally we beckon one, some or all of the concubines to join us from the adjoining room. In other instances, I am just with a concubine or two. The role of the concubines is to clean our house, cook and provide me sex. They receive a monthly salary
