After marrying River’s stepmother, I worked from home as a freelance photographer. My slutty stepdaughter loved prancing around in her skanky little outfits after her stepmother had left the house for work, driving me crazy with desire. I always thought it was playful flirting when I caught her eyeing my package or pulling down her shirt to show off her cleavage, but I never expected her to take it to the next level, until one day she discovered explicit photographs I had taken of her stepmother in the bedroom.
