Lady's please tell me what happen?

So when I was about 14 years old I always wanted to touch my mothers body, when we were alone at home I would ask her if I could massage her feet and lead to massaging her legs. I loved this so much, I rubbed her legs like I was going to have sex with her. I would rub my hands all the way up to her panties but would never touch her panties. I really wish I would of but I didn't want it to end so I played it safe. On time I was rubbing her legs and staying in the upper part of her legs, just rubbing her inner thighs good and she squeezed her legs tightly together and held them like that for a minute or two...... I think I have my mother an orgasm???
