The story is a work of fiction.
*****
Olga became the best friend of my wife, she started to visit us every day and she never entered our house without holding a present in her hand. Mary would send me to Olga's house on daily bases in the afternoon to clean it and follow her instructions. Mary didn't know that I served Olga's sexual needs, I was always locked with the chastity device, and she never knew anything about her deviations!
One Saturday Mary and Olga spent the night at our home and I prepared for them wine and dinner. They drank a lot of wine before eating, and I knew that it was Olga's plan. Olga went to me when I was in the kitchen and ordered me to get the strap-on dildo from her apartment; she told me that I had to wait in the corridor till she calls me into the salon.
I came back from her place quietly and I watched them from the corridor. Olga was hungrily French kissing my wife on the sofa!
Mary's breasts were naked and Olga was holding them firmly. She kissed my wife for a while before she moved to her neck and her breasts. My wife's weakness was at her nipples, when Olga took her time sucking them I knew that my wife was in total surrender!
Olga then stopped and stood to remove her clothes and Mary took off her skirt and laid naked on her back, she spread her legs widely while Olga rubbed her wet pussy...
Olga called me to enter and I helped her to wear the strap-on, she fucked Mary to the first orgasm and continued thrusting my wife's pussy for more than an hour, she was insatiable. Mary begged her to stop, so she shifted to her asshole. Olga came several times and I knew that my wife couldn't take it anymore.
Olga used to tell me that she was a lesbian since she was eleven years old. She loved to be a dyke and to dominate other women and men.
I knelt on the floor in front of Olga, licking the soles of her feet while Mary was asleep. She told me that she wanted her feet shining with my saliva!
Two hours of licking her feet was a dream full of pleasure and pain! I cried in tears because my tongue became sore and tired, but she didn't allow me to stop, she pushed her toes in my mouth and kept her foot like that for another hour! Then she whipped my back with a belt before I was allowed to go to sleep!
