Hot feeling

One of my relative's wife is really lovely and I like her, she has 3 children and 4 years older than me, I'll visit her 2 or3 times during a year for at least 3 days stay in our home. past year when I was horny I'v stolen her panty and kept it. I know she knew what I done but her behavior still normall, she likes me and I can feel her passion but the point is what is her feeling/thinking/.. about happening? and Is it ok to continue my job for get her hot spot? (I need females ideas esp)
