My wife Mary has a best friend called Kate and over the years they have often had girly weekends away and if Kates husband or myself are ever away from home the two girls always sleep over at one of our homes.About a year ago Mary and mines sex life began to increase in its intensity with Mary fantasising more and using toys. I thought nothing of it but I also became aware of the phone being put down when I got in from work and a general change in Marys mood although our sex life was just getting better.

My suspicions were further aroused when I was due to go away on business for one night. Mary was constantly checking I was still going to be away and when I would be back.
I decided that rather than stay over I would drive the 200 miles home and surprise her.

I got home about 11 pm and quietly let myself in, I sneaked upstairs and as I did so could quite clearly hear the sounds of two people having sex. Although I was the thought of catching my wife with another man I was strangely turn on and prepared to see my wife being fucked by another man.

As I pushed open the door the sight that I saw was one that will live with me forever. Mary was laid naked on our bed in a 69 position with Kate while Kate had a vibrator up Marys cunt. My cock nearly burst out of my trousers as I heard Mary call out to Kate don't stop I`m cumming.
Kate then looked up and cried out oh shit. Marys face was overcome with shock and there was an awkward silence.
Kate was the first to speak are you disgusted or turned on she asked. Mary then joined in by saying I can see the answer.Kate got up and went to the toilet.
Mary came over to me and kissed me long and hard.She apologised for me having to find out like this and said that it was her intention to tell me. She then told me all about how it started and that it was just about sex, sex between two very sexual women and that they had no intention of leaving their husbands as they liked cock to much, it was just the feel of another womans body that they both liked to enjoy every now and again.

My cock was still hard and Mary knew it. She said nothing would turn her on more than me watching her and Kate and me joining in. The only rule was that I was not to touch Kate.
Within seconds I was stripped off and Mary was sucking my cock. Kate came back into the room , my eyes followed her as she picked up the vibrator and sat in the chair. Boy how I wanted to fuck Kate as I watched her plunge that rabbit in and out of her wet cunt. I placed my hands on the back of Marys head and fucked her mouth shooting my load deep into her throat. Kate got onto the bed and Mary joined her a I sat in the chair. They kissed and stroked each other so tenderly, caressing their ample breasts and sucking and biting each others nipples. Slowly Kate worked her way down to Marys trimmed bush, pleasuring her with her tongue.
I slowly wanked my cock back to hardness as I watched my wife scream with pleasure as Kates tongue flicked from her clit to her arse.The girls then swapped places and I watched my wife pleasuring a woman for the first time. Kate was watching me and she ordered me to fuck my wife. As Mary raised her arse in the air my cock slid straight in to her sodden fanny. I was in heaven , I was fucking my wife while she was going down on her best friend. Kate and my eyes met and Kate began to play with her boobs, licking her nipples. She then looked at me and began to mouth the words cum, cum cum. That was all I needed to take me over the edge.

Kate left Mary and me to spend the rest of the night alone. Mary was eager to explain more about her and Kates relationship. As she did so my cock again grew hard, Mary straddled my cock and slowly rode me. She told me how much she enjoyed being fucked after her sessions with Kate. She then began to fantasise how it would be good to see me fucking Kate while she watched.
That has not happened yet but if it does I will let you know.
