My wife Pam and I have lived in Spain for 2 years. Pam is 36 and almost as tall as me at 6ft. Pam is very submissive and we enjoys slave and master roll play. And loves me making her go nude on the beaches near our house. We have talked about involving another lady to increase our sexual pleasure. So we placed an add in a contact mag and got a reply from a lady living within an hour of our place. She mentioned she was 34 and divorced but BI sexual which is what we were really looking for truthfully. Her name was Kate. We arranged to meet at a bar mid way between our homes the following week. Kate was very similar in looks to Pam dark black hair nice tan and a lovely figure. We sat on the terrace feeling really relaxed enjoying a drink in the sun shine. Kate asked if we were nudists?.Pam spoke up "Ron makes me go nude even on non nudist beaches". I was only on fruit juice as I was driving. Kate had got a taxi so the girls started really enjoying the wine. Both of them giggling like school girls. I went to the bar to order some snacks as we decided to invite Kate back to our place for an evening meal and stay the night. Which she was more than willing to accept. When I got back Kate told me that she would like Pam to be her slave as well as mine. I looked at Pam !. Yes darling we have discussed it if your happy I am happy. That's ok with me. Kate raised her glass of wine then "We are all happy". Kate smiled at me then turned to Pam from now you will address us as master and mistress. Pam looked at us. Yes mistress. Slave !! Kate instructed Pam go to the ladies and bring me back your bra a knickers. Pam returned in minutes and slipped her bra and tiny g string to Kate. Pam wore a pink cotton mini dress and her nipples could be clearly seen. I had an almighty hard on. Kate then quietly asked Pam do you feel naked. Yes mistress she replied. Because you can see through your dress if fact I can almost make out your pussy when you stand in the sunlight. When we arrived home that afternoon We all got nude by the pool and I asked Kate if she would like to fuck her slave while I wanked off watching. Kate stood up and looked at Pam. Come here slave I am going to fuck you. Pam walked over to Kate yes mistress I am your slave I will obey you. First I will examine your body. Kate had Pam in a dream fingering her cunt and telling Pam she would have her name put on her cunt ring as a sign that she was her slave. Pam was flushed. Ron! her cunt is dripping Kate indicated. Look!. I walked over and released my throbbing cock and rammed into Pam,s cunt. I withdrew my cock and invited Kate who had strapped on a rubber cock to fuck the slave. Never have I seen two girls enjoy SEX so such. I wanked off watching this erotic display. Kate later told Pam I will allow you to watch your master fuck me tonight you can with my permission use a rubber cock to bring yourself off. Thank mistress Pam said in a low voice. Kate then took Pam by the arm remember your just a slave to be use and fucked is that clear. Yes mistress. Kate gave Pam a long lingering kiss. TO BE CONTINUED.
