Jill has a few times posed nude for some artists. The first time she did it, she just thought that she should pose for portraits, and as they told her to strip it all when she arrived, she was so surprised that she did as told.
She got paid for it, but not much. Next time she did it, it was just for the thrill of showing herself.
