As we were sitting in front of the fire kissing I was looking hot in my tight t-shirt and lace boy shorts. She broke our embrace and said "lets go out to the wine store before they close we are all out". Although we had been out a couple times together with me dressed up I am still hesitant. "Just throw on a pair of jeans.. no one will know you are not a girl.. you look hot". This made me feel better so I ran up to get my jeans on and grab my purse. When I came back down my wife was heading out the door also in jeans and her hair pulled back under her baseball cap. My wife always drives now.. it has kind of come naturally since we became serious about Jamie.. she just grabs the keys.. and I follow, she even sometimes holds the door open for me, it's kinda nice. As we drove the short distance to the wine store in traffic she grabbed my hand and started to kiss my fingers.. she then brought my hand down to her crotch.. that is where I felt the hard lump in her jeans I hadn't noticed in the dark. I pulled back in a start.. "Kat! What is going on!". She smiled and said "You see how excited you have me? Pull it out.." " I can't pull it out! Someone will see! There is so much traffic!". "Thats the point" she said.. I WANT someone to see.. now pull it out!". As I was already very nervous this had me shaking.. but I did as she asked and nervously looked around as I unzipped her jeans and pulled out her large cock. "Good, now stroke it.." she smiled.. I wrapped my fingers around the base with my bright baby blue nails glowing in the dark. I glanced around again and started to awkwardly pump trying to see who might see but also concentrate on the cock." "This is good practice for you baby girl.. you haven't done this already have you?".. "You know I haven't!!".. I almost screamed. She then slowed down almost to a stop as a large SUV pulled up beside us windows blacked out.. "Don't you dare stop.. keep stroking me.. she had an evil tone.. "I wonder if they can see my baby stroking her mans cock?".. "Please let me stop I pleaded". I was starting to see that this was a plan.. a moment later she turned into the parking lot of the store she headed for a darkened corner. "You need to stop all this bullshit whining of yours how you are scared and unsure.. you better GET sure of yourself.. this is how it is..you are a girl now.. get over here and get your mouth on my cock NOW you little bitch!".. She caught me off guard and even scared me a little.. I jumped up on my knees.. balancing on the seat I leaned forward and took as much of her huge cock in my mouth as I could… she then grabbed the back of my hair and started to pull my head back and forth harder and further unitll her balls were on my chin.. holding me there for a second forcing me to relax.. she said "You are getting so good at that… you are a great cocksucker aren't you? I bet you are secretly proud of that aren't you?" She is not usually humiliating to me at all but this was borderline. She pulled my hair again.. "Let me see you lick the whole shaft.. slowly.. thats it baby girl make me want to fuck you..".. I don't get off on humiliation but for some reason this almost meanness was getting me really excited… she was too… I could tell she was getting wet.. "Ohh I can feel you sucking my cock.. YES keep going… I hope someone walks by so they can see how good you are.. "…. she then started to really rock back and forth.. she was really enjoying this… "Rub your pussy!! I want you to come right now!! I hurriedly shoved my hand in my panties and started to rub.. it did not take long for me to come in her hand as I have done many times before… she kept rocking in her seat as she smoothed the come onto the dildo.. she then grabbed my hair again and shoved her cock down my throat as my come coated my tounge I swallowed… pulled off and licked the remaining drops from her cock as I stared up into her eyes. After getting put back together we started the drive home. "That was so hot!". She was very proud of herself.. happy now.. "I wanted to do that for so long" .. "Can I ask why?" I said meekly. "Do you remember all the times you asked me to give you a blow job in the car like your girlfriends did in High School because it was your fantasy?… do you have any idea how much that hurt? After you kept asking, I started to get angry and as things changed between us, and I gained confidence I started to think that maybe YOU should be the girl giving the blow job in the car." "It is so fucking hot to me to think that I made YOU the girl in your fantasy instead and I just came in YOUR mouth, by the way.. you are lucky.. my original plan was to have a guy do it for me".
