My Sexy Diary

My name is Dorothy and I’m nineteen and live with my mother and my stepfather. They’ve been married for the last two years. I’m home on summer break from college. Mark, who is my stepfather, is really cool and we spend a lot of time together. My mother is a nurse at the hospital. She works from three o’clock in the afternoon, until eleven o’clock in the evening. I find Mark very attractive and really sexy looking. He is 6’3” and weighs around two hundred and twenty pounds. My stepfather loves to run and we have a treadmill and he runs on that sometimes, or sometimes he’ll drive down to the high school, and do laps around the track. I too love to run and sometimes we go together. I feel so comfortable around him. I do think I might have a little crush on him also. Well maybe even more than a crush. I fantasize about having sex with him. I know it sounds so strange, but we spend a lot of time together. He’s always telling me how pretty I am. He takes me shopping and buys me all kinds of things. I see him looking at me sometimes and it's not in a proper way. He’s always staring at my ass and breasts. I am 5’8” and weigh one hundred and ten pounds. I have curly, black hair, which is shoulder length. I have emerald, green eyes. My legs are long and beautiful and I have a large chest. I have a boyfriend and we've been dating for the last year. I told my boyfriend that I was interested in having a threesome. He could not believe I had suggested that, but the more I talked about it, ...

... he became intrigued. I even told him a little bit about my stepfather. I told him it would be really cool, if we had a threesome with him. We’re not related, so it really wouldn’t matter. I told my boyfriend that I was going to think of a way that I could have sex with my stepfather. I then told him, he should come over in a few hours and then join us, so we could all have a threesome together. My boyfriend is very sexual and the idea of sharing me with my stepfather, really turned him on. I was trying to think of a way that I could tell my stepfather that I had feelings for him. I didn’t even know, if he was interested in me that way. I mean he's married to my mother. I started a diary and have been writing all my feelings down. In the diary, I wrote down how I wanted to have sex with my stepfather and all the things I wanted to do with him. I even wrote about the threesome that I wanted to have with him and my boyfriend. I purposely left the diary on the magazine rack on his treadmill. I knew he would read it. I went upstairs to my room and waited for my stepfather to approach me about it. I knew he would come upstairs and want to talk about it right away. The diary was very detailed on what I wanted to do to him. I know my stepfather really loves sex. I hear him and my mother having it all the time. They must have it like five days a week. Knock Knock “Dorothy, I want to talk to you.” “Come in, Mark.” “I just found this diary that was on my magazine rack. I have to say it ...
