Stepdaughter's sex toy gift - Amai Liu

I am a pervert. I admit to it. My current wife and I have been married only a few years and my sex drive is still pretty strong while hers as gone kaput. What is there left for me to do but watch as much porn as possible and try my best not to stare to much at my wife's step-daughter who lives with us. It's pretty hard not to notice my step-daughter. She is almost twenty-one yet looks like she is younger, much younger. I have a thing for females in pigtails and my step-daughter likes to wear her pigtails all the time. This afternoon as I was on my way to the kitchen I heard a slight buzzing noise in my step-daughter's room. I didn't want to pry but I wanted to make sure all was ok in her bedroom. I opened her door to one of my all time favorite fantasies, my step-daughter in pigtails playing with her pussy. There she was, her legs open wide and the vibrating toy pressed against her pussy. She was in such ecstasy she didn't notice me watching her through the slightly opened door.
