My wife showed me an add in the personal column of a contact mag amongst a pile of books we bought at a car boot sale. It was for a private adult party. The magazine was was three months old but Linda was all for giving a ring to find out if it still functioned. So I rang the number and a lady answered the phone. I politely ask about the the add in the magazine. She said the party's still happened every month in fact we could come on Saturday if we wished. My name is Jill and my partner is Tony she said and gave me directions to her house. she said she was looking forward to seeing you Saturday and the cost per couple was 50 euro this include drinks and a buffet. We arrived at Jill house on the Saturday at 1.00 it was very hot. Jill and Tony met us and introduced us to the others. This IS Ben and Linda. All the others where in swimwear 12 in total. Jill then surprised us when she asked if we would like to be slaves or masters - mistress. As the slaves did all the serving and attention to the rest of the party. I would rather be a master i replied but Jill looked at Linda smiled and said a SLAVE Linda. Why not Linda replied. Ok follow me then. Linda and Jill returned to the pool area. I couldn't believe my eyes. Jill was leading out Linda on chain completely nude. For someone 35 she looked fabulous. Jill asked everyone to come and meet her new slave. Jill and Tony must be about 45 but still very attractive people. Jill had oiled Linda and fitted a slave collar. Linda looked every bit the slave with her shaved cunt. Jill then asked us to look at the size OF Linda's Clit which was showing between her cunt lips like a small finger. Everyone took a good look and one younger lady even fingered Linda's pussy. Linda moved slightly at the touch and the young lady promptly reminded Linda. Stand still slave when I examine you and remember your place. Linda was flushed. The young lady then ordered another girl we had not seen before who was also nude and wearing a collar. Finger this slave. The girl fingered Linda's pussy .Is it wet yes mistress the girl replied. We all stood around watching i was rock hard my cock aching. Some of the ladies came even closer to get a better view. Jill then walked up to Linda and handed a rubber strap on cock to the other naked girl and said to Linda I am going to allow you to be fucked for my friends enjoyment . Jill clapped her hands FUCK SLAVES for you mistress. Linda was loving this she yelled out MISTRESS JILL thank you. Ben. Jill asked i think you should become my slave also don't you. Drop your shorts AND YOU SLAVE POINTING TO Linda suck this cock i now own. I dropped my short i was nude but before LINDA was allowed to suck my cock. Jill decided to invited the ladies to feel my cock but i shot my load after all the fondling and cock kissing. Jill then said i will not allow you in future to cum either of you. You climax only with my permission. Linda and i both replied yes MISTRESS.
