Classy older lady

My to girlfriend's have been together for 10 years I moved in with them 6 year's ago. We live a different life style, They have sex with outher women, On my part they make the arrangements for women I can have sex with. It's been that way from the beginning of our relationship. I am 26 my girlfriend's are both 40+. So generally the women they pick out for me tend to be colder than me witch I am fine with that. This past weekend we had a stay over party a small one 6 ladies and three of us. A few years ago they had a good size room added to the front of the house. It's a undressing room for the guest before they enter the main house our place as always been a clothing free house all 6 ladies got to the house early Friday morning. But my ladies said they had s special lady guest for me for the weekend. I heard the front door open she was in the undressing room , when she entered the main house I was shocked how beautiful this classy older lady was she has a fantastic body and a perfect behind. She cam up to me and said I'm Sally and I am 57 years old I said I am Vic I am 26 she said she knew and had all ready seen photos of me. It was a little uncomfortable talking to her her body and her perfume gave me a raging hard on. She looked at it and said very nice and started playing with it. And said I have been waiting for this day for two weeks. Can we please get to the bedroom and get that thing inside me I really need to get off. This was 10 o'clock Friday morning I said yes mam that sounds great. We went to the bathroom she wanted 69 first that lasted about 15 minutes till she got off she said enough I want you inside me now I entered her and started humping she was really getting in to it she got off in about 10 minutes and said faster I want to get off again this is fantastic. I bumped her faster she got off she said now I want to fill you get off in me please. I bumped her faster she had her arms wrapped around me tight and had her toung down my throat. I could fill I was ready to get off I did and it was a big one she was screaming oooooooooooooo my as I was getting off in her then we laid down for a few minutes and she said we should go get a glass of wine we did a couple of the other ladies said to her sounds like you were having fun.
