My Step Mom Made Me Jerk Off

My stepmom caught me jerking off to Mommy porn instead of doing my homework. She's so fucking hot! I watch her in the shower and jerk off while I listen to her and dad fucking all the time. I left my door cracked hoping she would catch me. She told me my dad doesn't get her off anymore. I could tell she wanted to see my cock. She's a very dirty Mommy.
