Girl Wants to Try Threesome

When my dear wife, Mary, brought her friend, Saphire, to our place and told me she needed help because her boyfriend left her, I agreed to help her though I wasn't very happy about another person living with us. When I found out a reason of their break-up, I got very interested in the situation. It turned out she didn't want to make threesome sex. My wife offered to give her a lesson and that idea turned into a fantastic experience.
