I'm young but I consider myself a very sexual girl but I never thought that I would go this far to get what I desire. I'm writing this to see if Im not the only female that has done this. My parents are divorced and my father has always been there for me and has taught me a lot about nutrition and excercise because he is a personal trainer. I have always thought he was a nice handsome man with a nice body but a few months ago while I went in thru the back yard entrance of my house I heard a woman moaning and looked thru the window and saw my dad having sex with his girlfriend, I had never seen such a big penis in my life except in a porno. After seeing this I couldn't stop thinking about my father's penis. I had seen the way he looked at my butt and breasts so I thought to myself I can seduce him if I wanted to. One day my dad was talking about how expensive the water bill had become so later that day when he was taking a shower I decided to go in and shower with him. He was surprised to see me naked in the shower but I told him that we were gonna be saving money like that. He blushed, kept showering and then got out since he got a boner from looking at me. I tried this a few times and the same thing happened. Then I let him catch me watching a porno video and masturbating with my vibrator in my bedroom with the door open, I told him I thought he wasn't home and he just closed my bedroom door with a smirk on his face. Then a few days later I caught him watching wrestling on tv and decided to watch it with him and after half of the show during a commercial I got on top of him on the sofa and started wrestling with him and I grabbed his cock and give him head. I told him I wanted him and he got on top of me and we had sex. Him and his girlfriend are now having problems because he doesn't spend enough time with her anymore but he tells me she's a gold-digger type girl. He has me on the pill and we sleep together almost every night. He is my daddy in everyway now and I think I'm falling in love.
