Should I Test My Luck With My Old Friends Mom? [M/F]

Okay, so I graduated high school this past year. I haven't spoke to this friend since the 6th grade. Well somehow I came across his mom's (secret?) instagram profile with a fake name, but I know for a fact it's her. There are multiple pictures slightly exposing herself but not too much to be breaking the rules of instagram. The captions say stuff like, "need someone to come help me out", "i need help", "I need something." It's mainly just pics of her wearing lingerie, etc. Well, she is definitely a milf, there is no doubt about it and I would love to fuck her. I work at a local grocery store and she comes in there all the time. Well, I am strongly considering testing my luck with her. Should I do it? If so, how should I approach her about it? Keep in mind I am not worried about her son finding out, he is like 5'4 and weighs probably 100 pounds. What should I do?
