It came as a bit of a shock, but I can't say a completely terrible one. Andrea and I had just made love, and were lying in one another's arms in the warm afterglow. She had made some small talk about how it must be terrible not to have experienced an orgasm, or even to have sex for years and years. I wondered where she was going with it, when suddenly she sat up and looked at me, and asked me if I could consider having sex with her mother.
Apparently they had been having a bit of a heart to heart, and her mother told her that she had not made love to her father for over twenty years and missed it terribly. She also related that even when they had enjoyed a fairly regular sex life she had never had an orgasm. I know that is the sort of thing any mother and daughter might discuss, but I'm not sure how she came to offer my services. She just said that her mam had been so sad that she wanted to help her somehow. Of course, not having a cock she couldn't help her directly, but she said she would see what I thought of it.
I wanted to know that my fidelity wasn't being tested, so I replied that if that was what she and her mother really wanted we could discuss it. Within a couple of days we had talked about it, and laid plans for the big event. Lillian (my mother-in-law) told her husband, Stan, that she was going up to our house for the evening. She often did this as usually I was out on a Saturday night, as was Stan, and they would sit and gossip over a bottle of wine.
I had planned the whole thing carefully, knowing that Lillian would be very nervous. When she got here, Andrea took her straight upstairs to get ready while I prepared things. I had bought a lot of candles and arranged them around the room, and now went round lighting them, and scattered a few throw cushions in the middle of the floor. The light created was just right, not bright enough to cause any embarrassment, but enough to see what we were doing. I took the bottle of wine I had bought for the occasion out of the fridge, opened it and placed it on the tray with the glasses, and put the film we had selected to watch in the video.
I sat on the sofa and sipped my wine while I waited for my wife and her mother to come back downstairs, previewing the coming activities in my mind. Just thinking about it was enough to give me quite a hard-on, and when my two women came back into the room it was making quite a tent in my tracksuit bottoms, under which I was not wearing any pants. I didn't try and hide it – what would be the point – and Andrea grinned at me while behind her Lillian gave me a nervous smile, her eyes locked onto my crotch. They were both wearing dresses that buttoned right up the front, and high-heeled shoes. They both sat on the other sofa opposite me, and I switched the overhead lights off and started the film.
I had chosen the film quite carefully. It wasn't exactly pornographic – no explicit shots of erections or anything – but it was very erotic with some good love scenes. As the film got underway I took an opportunity to watch the two women seated across from me. Andrea seemed very calm, sipping her wine while she waited for the action to begin in the film, but her mother by comparison was very nervous. I noticed that her first glass of wine went down in a couple of gulps, but Andrea filled her glass up for her again, and as the alcohol began to take effect she seemed to calm down. It probably helped that she doesn't normally drink, so a couple of glasses had quite an effect on her.
As I watched them I tried to work out what they were wearing under their dresses. I had only put two conditions on the evening's event, the first of which was that they would both wear the sexy lingerie that Andrea knows I find so appealing. The second was that I would make love to both women, Andrea first, in the presence of the other.
I turned my attention back to the television as the noises emanating from it indicated that there was some good sex going on. A tall, slim, large-breasted woman with long blonde hair was bent over the dining table, dishes and cutlery flying everywhere, while the muscular hero of the film got stuck into her from behind. It was pretty realistic looking, especially when she turned around, lay back on the table and wrapped her legs around his back when he entered her again. He was licking and sucking on her titties, and banging away for all he was worth.
Andrea, while my attention was diverted, had begun to unbutton her dress from the bottom, pushing it aside so that I could see her crossed legs. She has the best thighs I've ever seen, and I love it when she crosses one leg right over the other. The effect was heightened by the fact that she was wearing her lacy top stockings, and as she loosened the last button and pulled her dress open, I could see that she was wearing her basque. She looked at me and smiled alluringly as I sat rubbing my hard-on, and I gestured to her to do the same to her mother's dress.
I half expected her mother to protest as Andrea began to undo the buttons on her dress, but I was wrong. She just sat and looked at me as the bottom buttons were loosened, but when Andrea spread the skirt to reveal her legs and lower body, she started on the top buttons herself, opening the dress so that I could see her breasts encased in Andrea's laciest Victoria's Secret Bra. In fact, she was wearing the whole range of Victoria's Secret lingerie that I had bought Andrea; bra, panties, suspender belt, and another pair of lacy stockings.
I couldn't believe my luck as I sat and admired them, my hand now gripping my cock tightly through my tracksuit bottoms. Lillian is not the most attractive woman who ever lived, but I could certainly see where Andrea got her figure. Even though she was getting on a bit her legs were just as long and shapely as Andrea's, and well toned due to the fact that she walks every day. The only drawback was the varicose veins she suffered from, but they were mostly hidden by the dark, almost opaque, black stockings, which is one of the reasons I insisted she wore them.
