My mom said she is my stepsister and asked me to fuck her and I accepted and we both fucked like rabbits, I loved every moment of it

I strolled in on my stepsis, a cute 18-year-old who obviously just stepped out of a gym. One thing led to another and we were in the middle of rather hot sex, so it was hot doggystyle sex. It was an unexpected, spectacular nuts with this petty slut.
