I'm 20 now, but I was 18 when this story happened.
Towards the end of my senior year of high school, my Mom got remarried to her boyfriend, "David", who I had always thought was really hot. He's about five foot eight inches tall, with short brown hair and a thin body. I had fantasized about him for years before but now he was coming to live with us. It was a big turn on. My best friend (who also thinks David is hot) told me I should try to seduce him as a joke, but I fantasized about it for months.
My Mom leaves first in the morning for work, and around that time, David is usually always taking his shower and I'm getting ready for school. Well, after my Mom left, I would try to sneak peaks of my step Dad in the shower.
He masturbates on a regular basis. I knew, because he sometimes would make noise in the shower and I would peak through the door and see. Whenever I would catch him masturbating I would rub my clit to an orgasm at the same time that he did. It was great!
One day, my Mom left for work and I went to the bathroom door to see David and of course there he was, rubbing his dick (it's about six and a half inches by the way, maybe seven I don't know). I started to rub my clit and then my heart started to pound like I was having a heart attack. Ever since my friend made that joke about seducing him I had been thinking non-stop about confronting David and telling him that I liked watching him masturbate but I really wanted to see him up close and not through the frosted glass door. I wanted him to watch me, too. I was afraid he'd tell my Mom and she would kill me, but I had to try because I'd been thinking about it for too long and I'd regret it if I didn't.
So I stood up, pushed open the door and walked into the bathroom like nothing was wrong.
"Carrie?" David said. (My name isn't Carrie, just so you know.)
