My stepsister discovers me pleasuring myself in my room while wearing pantyhose and halts me from continuing

My stepsister caught me in the act, her face twisted with anger. She stormed into my room, her pantyhose accentuating her long, shapely legs. I stopped what I was doing, my excitement fizzling out as she glared at me. This wasn\'t the first time, but the promise of punishment made me hesitant.
