My wife B has a naughty side that she does not realise i know about. She does flirt and does push the limits but often does not know i am watching. B is slim and average height and very attractive. She does draw attention from men easily.
One evening in summer we were at our neighbors house for a party. Our neighbors were new so we knew no one there. My wife and i were mingling in different circles on the night so were getting to know people.
Later in the evening once darkness fell, i noticed my wife speaking to a guy seemingly younger. I made sure not to let on i was watching. My wife was dressed in a shortish summer dress, very silky and sexy indeed.
He seemed to be very close in his chatting and she was not standing back. Her responses even included plenty of touching his arm as he spoke.
I reposition to allow myself to observe in such a way that they would not be aware of me watching. I could see now him occasionally whispering in her ear which had her smiling in response. This continued for some time. It was then that they both went to get a drink and then moved to another place where now they were more in an area away from the light.
Now was when he would whisper, she would smile and he would brush his hand down her hip gently. She did not seem to object. This moved to him now shifting from hip to leg below the line of her dress. Again she had no objection.
My wife really had no reason to feel nervous. She had long known that her flirting turned me on. I had frequently told her i was ok with it. She would ask, what if they were to try to go further? I would simply respond with a smile and say, "its up to you how far it goes".
