I was talking with my step-sister Dolly the other day after my boyfriend broke up with me and the strangest thing happened. She started getting a bit aggressive and almost towards him then started complimenting me in a very sexual way. She leaned in and kissed me on the lips and things went sideways from there. We wound up in our parents bedroom stripping each other on their bed. I'd never been with a woman but my step-sister had at least once, she was really experienced and soon we were both cumming like crazy. Who needs men when my step-sister makes me cum like this??
