Many years ago my mother-in-law commissioned an artist to do a painting of my wife (her daughter) and our children. My wife, thirty-one years old at the time, went to his studio with the kids and the painter told he wanted to sketch the boys before they got bored and the wife in a second time. In two session the kids were done so the wife begun to pose going there alone. Four other sessions and the wife was ready too. On the last day, taking a break, he got her a glass of wine and they chatted for a bit. He told her that she was very attractive and an excellent model and asked her if she might be available to pose for other paintings. For a small fee of course.
She was very flattered and said she would love to, just give her a call. In a week the painter called. He had to do a series of portraits and female full figured paintings for a gallery in a nearby town and thought at my wife as a possibly model. She had a lot of free time in those days, the kids were in school and she wasn't working. Money wasn't bad and she went. The painter gave her a drape to wear for a bare shouldered pose and very politely he asked the wife to leave her bra off just to avoid ugly marks on the skin. My wife did it without a problem and started to pose baring a shoulder. In the beginning he took a lot of pictures to progress the work when she wasn't available, then she posed for a while he sketched and painted. They did small talks and very politely he asked her if she was embarrassed posing bare breasted under the drape or she was cold. It was pretty warm in the studio and she admitted to be perfectly at ease. So he mentioned the possibility to pose naked for an extra money. They discussed the extras dealing quickly, then she removed the drape baring her small breasts. So there she sat topless for about another hour.
She seemed to be spending a lot of time posing for him but he had twenty paintings to do for the aforesaid gallery and the sessions lasted about two months.
