Hardcore missionary sex in the car with my insatiable blonde wife

I fucked my mother in law on the backseat of my car! I had to bring her back from her break in Scotland when I arrived at her sisters house I had a drink and a sandwich, time was getting on when we left,driving for a while,my mother in law said she needed a pee, luckily pretty soon we arrived at this lay-by I pulled into it I said you should be okay peeing here there’s not much traffic on the road, I opened the back door while she stood between the opened car doors she lifted her dress up took her knickers off then began to pee she asked me to keep a watch out for traffic, I told her I’d prefer to watch her, she giggled saying you’re enjoying watching me, I said I know I am! She said pass me my bag for a tissue, I told her she doesn’t need a tissue I’ll wipe her if she gets on the backseat! She did, legs apart I began to lick her pussy she soon cum, she told me to take my cock out which I did she held it say it’s very stiff, put it in my pussy, I slipped it in then began to fuck her slowly at first, she clamped her legs around me telling me to get deeper at that point a car was passing phew! It carried on, I carried on fucking her thrusting deeper, she said it’s the first time I’ve ever had sex in a car, I told her, I’ll do my best to make sure it’s not the last, she was on the verge of cumming so was I, we both cum then she asked for her bag with tissues in we cleaned each other threw the cum filled tissues in the bin she got back in the front seat , we carried on with our journey. She told me I’m the best thing since the tv remote and sliced bread.
