Riding my Sister and Moms pantyhosed leg

My sister always wore short skirts, tights and clumpy platform shoes to school. I was always trying to get her or one of her friends to loose one shoe, one day I walked home from school with her,slightly behind her. I noticed that her left shoe was slipping off her heel. I grabbed the moment and stood on the back of her shoe so it came off. She thought it was quite funny, but I said that she had to walk home with only one shoe on for a dare.
She said ok, I will walk and hop if I have to, I know you like it and I don't mind, it will be a laugh.
Ad we got nearer home on a quiet lane, I said can I ride your shoeless leg. She asked how we could do that, I said there is a wall just here and nobody is around.
Stand against the wall and lift your left leg out behind you and I will straddle it.
This she did and I rode her outstreched leg and rubbed my self on it for a few minutes.
I had a very erotic time and she said it felt quite kinky.
We have done this many times over the years, she has even persuaded a friend of hers to let me ride her shoeless leg.
A few years ago, I was talking to my Mom about things and the subject about me always trying to take off one of Moms shoes. I confessed all and she said don't be ashamed, it is just a harmless fetish. I will let you ride my leg, we were in the kitchen and Mom was wearing pantyhose, a black short skirt and 3inch court shoes,as she had just finished work. She took off her left shoe and lifted her leg up on tje kitchen stool, I sat astride her leg as she did so and rode her leg. It was amazing. To this day I still make Mom loose a shoe when no one is aroumd.
