My wife Jo and I have played out the slave and master game for years. Jo is part Italian 5.10 tall very slim with small beasts dark shoulder length hair and beautiful olive skin. Jo is 34 and we have no children . We live in the Spain where I am a partner in a cleaning company. This allows us a lot of spare time to indulge in our passion for nudism and sex. Recently we went to an adult club and met Kate an English divorcee about the same age as Jo. Kate quite openly admitted to being bi sexual which seemed to interest Jo somewhat. Kate invited us to her home the following . We arrived and Kate greeted us warmly and kissed Jo full on the mouth. It seemed to go on quite a while without Jo minding. In my mind I could see them fucking. I got an erection just thinking about it. We all went for a swim in pool all of us nude as Kate prompted . We had a lovely lunch and Kate asked if we would like to stay the night and not worry about having a drink and driving . Jo spoke up "Oh that would be great" . We enjoyed the wine and felt really relaxed. Kate was a little tipsy later on . And she began talking about sex and telling us that she had lost her young housekeeper a French girl . Who had to go home because of family problems. Well to tell the truth Kate said she was my SLAVE. Jo stood up "I am a slave too" to Rob. My mind was racing. I looked at Jo then Kate "Why don't Kate and I share you Jo as our slave. Jo walked over to Kate " I am your slave" . I walked over and ORDERED Jo remove your cloths and told her to address Kate and I as master and mistress. Jo stripped . Jo stood naked in front of us . Kate took hold of Jo and kissed her then told her to stand with her hands on her head and legs slightly apart. Kate turned me I will examine my slave. Kate ran her hands all over Jo. Rob we have a fine slave here smiling at me. Are you horny slave ?. Kate asked. Yes come the answer. Kate slapped Jo not hard or hurtful. You slave will address me at all times as mistress is that clear. Jo looked flushed and replied yes my mistress . Kate then ordered Jo to bend forward so as to examine her cunt from behind . Kate put her finger into Jo turned to me having removed her finger look Rob the horny slut is dripping . Kate then toyed with the slave ring in Joes cunt. You may stand slave come the stern command from Kate, Rob ! Kate asked would you mind if I fucked my slave. I was dying to see this . And I replied please go ahead . You could masturbate while we fuck Kate stated quite matter of fact. I watched Kate and fuck Jo into uncontrolled passion with her strap on cock. Oh mistress I am your slave do what you like with me came from Jo as she began to cum. I had an almighty wank. That night Jo masturbated while I fucked Kate . Before going to bed we had Jo bath Kate and get on her knees and kiss Kate between her legs . Kate gave one final order before we all went to bed . Slave you did not ask me to allow you to cum when I used you. In future you will beg your mistress allow you to cum. Is that clear .Yes my mistress came a slave like reply. Kate took a leather strap. Bend over slave and take three lashes on your lovely arse. Kate gave Jo three lashes more to show who is mistress than hurt Jo. On the way upstairs Jo whispered I think this will work out fine MASTER.
