Thank you....women are very competitive about sex with the same man....friends, coworkers...but women who are related...VERY competitive. I have many times had sex with women who are related to each other.
Yes, sisters and cousins....but also women who were mothers to their daughters I had sex with...as well as grandmothers and granddaughters, and aunts and great aunts and nieces and great nieces....in one family I had sex, over time, with all four daughters/sisters and their mother...as well as the mothers sister....the aunt of the four sisters.
And in another family...going back decades to when I was very young...I had sex of some sort with three generations of one family, and in the many decades since...two more generations that were not even born when I was first having sex with the women who would be their great, great, great grandmother and great, great grandmother, and great grandmother.
