Step Daughter

My stepdaughter is turning into quite the woman. Her bra makes her look bigger than she is. I think about her when I masturbate. I usually get a pair of her underwear out of the laundry to sniff while I jerk off. This has been going on for a few years. She doesn't know it but I let her walk in on me one time. I heard the door open and I couldn't stop. She walked by looking but didn't say anything. I read her diary and she wrote that she came home and saw her step-dad rubbing his penis. I know it isn't the best but she does leave her panties on top of the hamper.
