My fertile Mother-in-law

I guess i will start at the start of everything. I married my wife when she was 20 and i have known her for 2 years before that. I have always had a little thing for her mom who is only 18 years older than her (yes she got knocked up in high school)and she has always seemed sexy to me.

Well we have been married for a few months now and the other the other day her mother called and wanted to see if i can come help her put up all of her christmas decorations (her husband is out of the country on buisness)and she can not lift everything.

Well i arrived at there house and saw that my mother-in-law was tring to get everything off of the tree. First i will tell you she always wears these shorts that come up her thigh and you can see about everything and she hardly wears a bra when she is home but what i have always loved is that she is not trying to be sexy she is just happier dressed like that.Well back to the story,i walked in and she is standing on a chair trying to reach the top of the tree so i go over and see if i can help. Well as i was walking up i saw her start to fall backwards so i put my hands out to catch try and catch her and got more than i expeted because my hands went right up her shorts and i got a feel of her uncovered pussy.She was really suprised and let out a yelp and jumped of the chair,and you could tell she embarrased,as i was embarrased too.She looked at me and said "what in the hell do you think you are doing?". Well i looked down at the ground and said"I'm sorry but you were falling and i tried to help you,i was not trying to touch you...well there".
So she came up to me and gave me a hug and said "thats ok,i am really horny and it felt really good plus...well i have not had sex in over 10 years and it felt good having a man hold me"

Well thats all i needed because i reached in to her shorts to get a better feel and all my god was she wet,so i rubbed her pussy with my fingers and was suprised when she lowered herself down on them and my fingers slid in with a moan from her and she was already gushing fluid out of her pussy,so i lowered her on the couch and took her pants off.I looked up and saw she already had here shirt off and was licking her own breast. Well i took a look at thevery pussy my wife came out of and it got me so hard,that i just put my face in here and ate her out.She came at least 3 times before she pulled me up and said "baby fuck me like i have never been fucked before". I pulled my pants down and rubbed my dick on the outside of her pussy and asked her "are you sure you want to do this?" and she said"every since i met you,i want you in me so bad and if i was not on the rag 2 weeks ago i might have tried than" So i started to put it in her slowly but she grabbed my hips and drove me in her..very deep.I started moving in and out at a good pace and i could already feel my sperm building up but i could not blow yet,and at that same time i felt her cum so hard i almost let go. Her juices were just flowing on to the new couch as i was driving in her,and she came again,on my i can't keep my sperm in so i kissed her like never before and drove my dick as far in as i could and at that time i let out the best orgasem i have ever had,i pumped cum shot after cum shot deep in her womb and i just could not stop.

To finish my story, we never again had sex but that was all it took because a little over 9 months later she gave birth to a healthy baby girl (who knew you could get pregnant at 40)and nobody ever suspected anything.......or did they?
