My cat was doing that to my leg, usually when I was sitting at the computer, and I just shood him away. Then one day he just kept coming back, I finally stood up and said what do you want????? He meowed, took a few step, meowed. I followed, which is what he wanted. His dish was empty!! He uses that "touch" all the time now. He leads me to the window he wants opened, to turn the kitchen tap on for a drink, to get past his brother (the alpha cat) who's lying in the hallway blocking the entrance to the bedroom where he wants to take a nap, to the "brushing spot" or to the kitchen counter where the treats are (he does't always get one). His brother pushes his head on my leg to get my attention for most of the same reasons. Not just a rub, this has force! Between the 2 of them I spend a good chunk of the day being told what to do! Feed me, brush me, open this door, make him move. They are indoor cats and I, apparently, am their entertainment. My advise is to shoo the little gal away and don't look into her eyes. Save yourself!
