Walter and Grace asked us what we were reading at the university. Katy explained that she was hoping to do Law and go on to take Accountancy as she wa...ted to play a part in the business when she finished. This was what her father had advised. I told them I would major in psychology. Alice told them that she was doing chemistry and then going on to medicine.Grace laughed and said that Katy and I could make a valuable contribution to the firm and we could always look to Alice to keep its staff. I watched her tits squish out to the sides. She started licking that pussy with all of the enthusiasm that I had hoped for. I had always imagined my wife with another woman, just never with her own sister. That was without a doubt the sexiest thing that I had ever seen. Now that I had promised my cock and cum to the winner, how could I tell my wife that I wanted to fuck her sister and that she had won? After all she was certainly giving it her all.When I was ready I simply said, “You won honey. When my wife finally got her cock all the way inside me, she held me by the hips and began slowly moving the entire length of the dildo in and out of me. She gradually gained speed until she was literally slapping her hips against my battered and bruised ass cheeks. I sniffled and cried while my wife had her way with my ass. To my genuine surprise I stayed rock hard the entire time. When my wife was done raping me, I was again tied spread eagle on the bed. Mistress Lynne and my wife both. To make me like the others and, for a girl like me, that was hard to obtain. Something in me, maybe something my parents did to me while I grew up, made me a different person. My dad a Major in the army and my mother a judge… My life had been ruled and watched until I got to high school, but when I finally got some freedom I was already too damaged to enjoy it. I couldnt stand boys of my own age. They looked so… Stupid… But it didnt stop me. I knew what I wanted. Soon, just as we entered.
