My wife has always been a generous person. She has been a realtor for a number of years and from time to time has been in a 'partnership' with another female agent in her office. One such agent was Susan, a hard working and very outgoing realtor whom had just moved from another city. As Susan's house had been subject to re-decoration my wife had invited her to stay at our house. We have a large suburban two storey house with lots of space, so it was no discomfort at all. Susan is a vivacious, early thirties reddish brunette with a very attractive figure.
The other thing I should mention is that my wife loves sex. She is a late 30's tall, lithe blonde. I often hear from the wives of friends about how she enthusiastically talks about our sex life. I have made it my job to continue to give her something to brag about!
One night when we were alone, she had mentioned that Susan had been so involved at work that she had been neglecting her social life in a new city. This had meant that poor Susan had been getting seriously in need of some sexual gratification. I jokingly asked if she was asking me to have sex with Susan? It had not been what she had been getting at. Rather, my wife wanted to put on a sex DVD in our TV room and encourage Susan to get herself off by then doing the same thing, ourselves. Apparently this had already been the subject of some conversation between Susan and my wife.
Sure enough, the three of us had gathered on the sectional sofas in the TV room, relaxing after dinner. My wife had made a comment about being in the mood for a 'a sexy movie' and had put in a porn DVD into the player. Minx that she is, she unbuttoned her blouse, slipped out of her slacks and panties and then sat down beside me. As the movie rolled on and the scenes got hotter my wife pulled open my pants and exposed my cock and balls, stroking both with a free hand. I had predictably got harder and quietly had expressed my approval. She used the other hand to rub between her open legs, moaning a little as she slipped her fingers into her vagina and through her wet labia. Susan had opened her legs and had hiked up her skirt. She was busy herself, looking over from time to time at our obvious abandonment of any inhibitions in front of her.
Finally my wife asked Susan to get completely naked and to turn towards us. She asked Susan to masturbate herself in front of me while my wife had pumped my cock, so that I would 'spurt my approval'. I couldn't believe how hard this was making me watching gorgeous Susan, whom I had barely known, wantonly bring herself to orgasm in front of me! My wife had taken over jerking my cock, slowing a little from time to time to not get ahead of Susan, but while telling Susan that my watching her frig herself and sink her fingers into her vagina was becoming too much for me. Susan began coming, howling, shaking and moaning as she did, juices freely running from her pussy and glistening on her fingers which she had rubbed onto her breasts and erect nipples.
I finally blew a big load in a spewing arc onto Susan as did my wife catching the rest herself. When Susan and I were both spent, my wife just lay between us and made us touch her until she came, furiously jilling her clit as she did. Eventually I did fuck Susan with all three of us together, but that is not a story for his site. We happily lived together and without a hint of problem kept each other satisfied for another five weeks. Susan remains a good friend that we continue to 'see' from time to time.
