[mukesh99]

My name is Mukesh Agarwal. I am 30 and married. My wife name is Sikha. she is 30 also. 2 months ago i visited my Uncle Rajesh Agarwal age 47and his wife Nilam 45. When i visited there house i saw that one black man name Alex also live with them. Alex treated aunt nilam like his wife. when me and wife saw than we think 3some sex is normal. so i asked my uncle who is this man living with them. my uncle told me that he is his partner and wife nilam husband. we get shocked that uncle calling that man as his wife's husband. than uncle Rajesh explain us that they have a group marriage. his wife married him together same time and this is normal there. we saw them they live very normal. After staying with them for a month we return.
