Fucking the wifes best friend

Met through a club we are both in and my wife and Mandy became good friends, ive loked after all our k**s while they go to the movies and stuff.
Anyway We were all at a mates party and Mandy and I were talking, she mentioned that she hadn't been laid in like 6 months, I asked if i could be of assistance in this issue and she just looked at me with a strange look.
Ive been keen on her fr some time.
Anyway we moved out to the verandah, there was no one else out there so we sat down on one of the lounge chairs. Pretty soon my hand was caressing her leg and moving up around her pussy, through her tights under her skirt I could feel how soft she was, mandy mentioned that she was shaven, My wife is quite hairy and doesnt like to shave or wax, so this was a real turn on.
As we were alone fairly soon my hand sliped under her tights and I could feel her skin, I love how soft women are. my hand moved to her pussy and it turns out that Mandy was wearing a g-string. Spreading her lips I fingered her for a while, Looking at Mandy's face i could see that she was enjoying the moment, her lips parted slightly and breathing heavily.
The verandah door opened and I quickly removed my hand, My mate asked what was going on, "oh just talking about her new car"
soon alone again we moved into the shadows and pulled each other close together, i could feel mandys chest pressed into me, her leg wrapped around mine.
We kissed and i found that mandy is a real tongue gal, she wanted me to suck her tongue which I gladly did.
That was about it for that night.....More happened a couple of weeks later.....
(and hopefully tonight as well)
