After our second ‘encounter’, Laura and I met on the Monday after work in the coffee shop for our usual chat. I mentioned that Sally thought she was a lesbian and she laughed. She went on to explain that, when she split from her abusive husband several years ago, she had been totally ‘off’ men and, having been comforted by a bi-sexual friend, she found solace in her arms, which resulted in Laura becoming bi-sexual too. She said that she was due to go to a family wedding about 100 miles away on the following weekend, which would involve an overnight stop, so we would not be able to have a ‘get-together’ that weekend. I remembered that, on the following weekend, I was due to attend a conference 200 miles away, so it looked as though we would miss our carnal pleasures for 3 whole weeks. Laura said it would make us look forward to the next time with greater anticipation, she said she could almost feel the tingle now. In the meantime, we could meet for our brief chats in the coffee shop to ‘catch up’ By the Wednesday evening, Sally was in a much more conciliatory mood and I even slept in the main bedroom with her that night. I had no desire for physical contact with her, but it seemed to go some way to resuming the normality of our relationship. At the coffee shop meetings, Laura and I tried to find a quiet corner, so we could have a fumble under the table, but this was not always possible. The weekends when we were not able to meet were sheer purgatory. Sally was really nice to me when I came home from the conference, even giving me a kiss on the lips in the hall. I couldn’t make out which direction she wanted our relationship to take, but I was certain I wasn’t going to give up seeing Laura. Laura came round to our house the following Saturday evening and she and Sally were immediately very chatty, it was almost as though they had become close friends, which spooked me a bit. We drank a couple of drinks as it seemed more of a social evening and I was pleased that the tension in the house had disappeared. When I reached out my hand to Laura to go upstairs, she said “oh Sally says we can use the king sized bed in the main bedroom tonight”. I was just thinking ‘that will be nice, it’s more comfortable than the spare room’ when Laura continued “there will be plenty of room for all of us”. Sally had got up out of her chair and was walking towards the stairway behind us. She put her hand on my waist and said “oh you lucky, lucky man”, and we all went upstairs. I realised that Sally and Laura had been conspiring during the previous couple of weeks, but I was not too sure what they had in mind. It transpired that, after her split with Dave, they had begun talking as friends in the staffroom at work, and Laura had made a pass at Sally. During the weekend I was away at the conference, they had ended up in bed together and Sally had realised that the touch of another woman could be just as addictive as a big black cock. To cut a long story short, I fucked both of them, not one after the other of course, but I fucked Laura shortly after we went to bed, and Sally the following morning. In between, I gave both of them a good seeing to with my tongue, which gave both of them an orgasm at different times, but it was nothing to the orgasms they gave each other. I even poked a finger in both of their bums, which Sally had never experienced before, she made a point of telling me the following day that she had loved it and would I do it again sometime. Enjoying the carnal pleasures of 2 so different ladies at the same time – Sally very slim and athletic, Laura warm and curvy - was wonderful. Lying in bed beside them in a 69 while they pleasured each other and being able to stroke them both was just so erotic. I was woken at about 5.00 am by Laura getting dressed, so I got up too to escort her home. When I got back into bed with Sally, she snuggled up to me and we drifted off to sleep again. When we finally woke at 9.00 am, we began caressing each other and Sally realised I had an erection again and, needless to say, we fucked. I realised afterwards that this was the first time we had fucked for many weeks, certainly since before she had met Dave, and it felt good. I have also realised that Sally and Laura are lovers, and I am simply the catalyst that has brought them together. They each refer to me as being their lover, which makes me feel like the alpha male in the house, and I delight in planting my seed in both of them each weekend. In fact, Laura has started visiting our house occasionally during the week, and it has crossed my mind to invite her to move in.
