My sister moved in with hubby and I some years ago. She works for a non-profit charity and loves it but her salary is almost non-existent. Hubby and I do not charge her rent. A while back she confided to me that she could hear hubby and I going at it and said it makes her extremely horny. I approached hubby about it and we decided to bring sis on on out sexcapades. We're not Mormons but now live together as two wives for hubby. At first it was awkward but in time, it became a wonderful lifestyle for the three of us. Unlike Mormons, we do threesomes and have a lot o fun at it with hubby keeping us with us sisters.
