I Couldn't Help Myself

My name is Bob, I'm a married, retired police officer and I've been best friends with my former partner John, who's also retired from the State police. We've known each other for 20 years. We are still in our 40's.
John and his wife have a daughter, Maria who just turned 18.
My wife and I don't have kids.
I've watched Maria grow up. She is unbelievably gorgeous. She has a body that won't quit! I hate to admit that I have jerked off countless times thinking about her
I never imagined that I would have my way with her, but my perverted fantasies finally came true! And, boy are they perverted!
It happened last Saturday. I went to a local bar with a buddy of mine and it so happens to be where Maria was with two of her friends.
She was shocked to see me there and very worried that I would tell her parents.
And, she was very drunk, which I later used to my advantage!
She came up to where I was sitting and nervously began apologizing and was begging me not to tell her parents!
I was getting a kick out of it and began formulating a plan to get her pussy!
I told her not to worry and I even bought her a few drinks.
It was getting late and close to last call when her friend said she wanted to leave with the guy that was with them. I said I'd drop Maria off. Maria hesitated but said ok, because it was obvious that her friends were into each other and were going to go fuck!
Finally, we left the bar. Maria was stumbling and so I grabbed her arm to steady her.
I was so fucking excited to get her alone and my thoughts were dirty, quite dirty!
We got to my car and she was next to me, laying back on the seat with her legs open somewhat.She was wearing a cute, yet sexy short summer dress. It accentuated her gorgeous tits and came up to her thighs.
My cock was raging hard!
I asked Maria if she wanted to go home or if she wanted to go to my house to sober up a bit.
I told her that my wife was away for the next week so she didn't have to worry about her saying anything.
Maria said her parents thought she was spending the weekend at her friend's so it didn't matter.
Oh boy! She had no idea what I was thinking about! Maria, naked, and all to myself!
