We live in a large old house and decided to have acouple over fro a meal, that we'd known for years. Our friends are called Babs and Dave. We are Jack and Helen. Babs has for some time been flirting with me, but I have not taken her on until now. After Dinner Helen asked Dave if he could have a look at our computer, which had been playing up a little. Babs and I sat talking in the lounge and we were all quite merry, when she said that Dave was tiring her out, because he had quite a high sex drive. I thought we might have a bit of fun, so I suggested to Babs that Helen could be set up, to help out. We hatched a plan and this was the outcome. Helen and Dave came back into the lounge and after about half an hour, I asked Helen if she could get some more ice from the freezer in the garage, whilst I poured some more drinks. About 30 seconds later I followed Helen into the garage, which is a the opposite end of the building. Babs then persuaded Dave to go along with the set up. When I got to the garage Helen had just finished filling the ice bucket and was surprised to see me. I said that I had to come out as Babs and Dave had started to get a bit passionate and I thought I'd leave them to it for a dew minutes. I said that since we had a bit of time to pass, why didn't we do the same. With that I turned Helen round to face the freezer, unbuttoned her dress, unclipped her bra and removed her thong and took her doggie fashion, which is her favourite way. When we finidhed I told helen just to put on the dress, as I will be taking it off again soon. I said that we needed some more wine and that i would walk down to the shop, about 10 minutes down the road and she could go back into the lounge and keep our friends company. When Helen got back into the room, Dave was laid on the settee with earplugs in and a blindfold on, other than that both he and Babs were totally naked. Babs was sitting beside the settee and she was slowly wanking Dave. She beckoned Helen over and invited her to feel Dave's balls. At first she was aprehensive, but with a little persausion she satrted to carress them, using the opposite hand to the hand Babs was using, so as not to let Dave know there were two women playing with him. Babs asked Helen to move her hand up onto Dave's cock and Babs then removed her hand, as Helen was now wanking him on her own. Babs said that she needed to go to the toilet and for Helen just to carry on. Babs gave Dave a squeeze of the arm, to let him know thegame had now started and that Helen was the one wanking him. Dave asked why Babs(Helen) hadn't taking his cock into her mouth, as he loved that, Helen concerned not to be found out, decided to take his manhood into her mouth and started to get really turned on with the idea that this guy didn't realise that it wasnt' his wife that was playing with him. After a short time Dave asked her to get onto the settee and give him a good shag. Again Helen was worried about being found out, but all her inhibitions were out the door. She quickly removed her dress andclimbed on top. She was getting into the rythm now and had got to the point of no return. She knew that he was almost there, as she felt his cock starting to set a faster pace, towards his climax, just seconds before they both came, Dave reached out feel Babs(Helens) tits and let out a gasp of surprise and ripped of the blindfold. It was too late for either of the, the fluids had started to flow. Helen, accepting the inevitable fell on top of Dave and started to kiss him passionately. There the story could have finished, but Babs wanted more relief than just one night and a more permanent plan was devised. 3 days later Babs phoned to see how Helen was and asked what she was doing that night, Helen said nothing at all, expecting her to say that she was coming over as she usually does. But Babs said that Dave had enjoyed their little escapade do much, that he'd like to do it again that night. Helen was shocked at this comment and asked Babs to clarify what she'd said. Babs said, look this is what we do, you tell Jack that we're having a girls night in and that I'm going to give you a massage: just put that short satin robe of yours on and get him to drop you off. Helen showered and spent some time getting herslf ready. I went into the bedroom, bent oven to give her a kiss on the neck. She smelled buitiful and I noticed, glancing down, that she had shaved her pussy totally bare, This she hadalways refused to do for me. She explained that since I was dropping her off, and she was going to have a massage, that she would just wear her shorty satin robe. Helen had a couple of gasses of wine as she was getting ready and then it was time to go. I dropped Helen off at Babs house and she went straight in (as instructed0 and went into the kitchen, where Dave was opening a bottle of wine, Dave was also in a shorty robe. They spoke for a short time as they drank the wine, Helen drinking a little faster than normal, dutch courage i suppose, but this added to what she had in the house made her very merry. Dave asked her to open the dishwasher door and put the glasses into the bottom drawre which was empty. As she did this, she obviously revealed what she was there for and Dave put his hands around her waist and pulled her close to him. She could obviously feel his enhanced start of readyness (as Helen was too keen to tell Babs about after) He put his hands into her robe, pulling it appart and letting it fall to the ground. Helen turned round and started to kiss Dave with an urgency that surprised him. She put her hands betewwn them, undid the belt on his robe and let it fall to the ground. She was eager for it now and Dave was only too pleased to assiat. Hecarried her upstairs to the bedroom where they did what she was there for. 2 hours after dropping her off, I returned to Babs house. Of course during the 2 hours i was away, Babs and I had it off for the first time. Helen came out of the house on cue and got into the car. She gave ne a peck and said that she'd had a wonferful time and would it be OK if her and Babs did this every Tuesday. How could I refuse. I asked if the massage was a turn on for her, as I noticed her robe had seperated and her pussy was glistening in the street lights. She said it was a huge turn on. I suggested that if it was a huge turn that when we got home we should make the most of it, to which she agreed. Three months have now passed since that dirst evening. All four of us are happy with the arrangement and Helen still thinks that I'm unaware of what's happening. Over the three month Dave had been talking to her about sex and what she enjoyed and what her fantasies were, something that we had never spoken about. After the first month he had found that Helen fancied a threesome and Dave said that maybe sometime they could do that. Last week it happened. I dropped Helen as usual, in the usual satin robe, at the usual time, but Helen had said that Babs wanted a little longer tonight, would I leave it for three hours instead of two. Helen went into the house, had her srink in the kitchen and went up to the bedroom. After they had come, Dave announced that he had a surprise for her. She had to be blindfolded and the bottom of the bed. The door opened and she sensed that someone else was in the room. A body came up behind her and she knew it wasn't Dave, because this guy had a huge erection. Hands started to carress her tits, one of them working its way down to her very wet pussy. She was almost on the verge of callapse as she orgasmed. He put her hands on the bed and entered her from the rear, again she came. He then laid her onto the bed and once again entered her from the front and she could feel him coming, something told her that she should take the blindfold off, but she decided not to. Again as had happened before in our house, on that first fateful evening. The man removed the blindfold, just as he was coming. Helen let out a cry of surprise as she looked at the man above her, the man who was my best friend. He doesn't know that I know, because Babs and Dave have told him to say nothing. What happens next? I think Babs wants to get my friends wife involved, with both Dave and me, but without my friend knowing about it. It is getting complex.
