My wife does some part time work posing for art classes, one of the guys in a class asked her if she could pose for him in his home studio which she agreed to, he wanted to sketch her in various erotic poses, we thought it would be fun so she went along with it so long as we could have copies of the pictures, the session lasted a couple of hours and my Wife told me he was aroused the whole time, judging by the bulge in his trousers, at the end she said "do you want me to help you with that?" pointing to his cock and within seconds his trousers and underwear were off and his hard cock out, she spread her legs and invited him to fuck her, he pushed inside her and almost immediately shot his load, my Wife said "well that was quick, I was expecting a bit more than that" wiped herself and got dressed, she came home and had to use her vibrator as I watched as she told me all about it. I licked her out afterwards.
