Not long after I married my wife we attended her sisters 60th birthday.Now my wife was the youngest of her family and we were in our early twenties when we attended big sisters birthday.This was just the second time I had met Cindy the first time being at our wedding.Cindy was and is a very attractive mature lady and I must admit that when I first met her I thought I would love to fuck her and had wanked many a times thinking about that beautiful cougar.So we arrived at Cindy and Greg’s place a day early and hung out with them and helped prepare for the birthday.After working most of the day we decided to get pizza for dinner.I offered to go pick up the pizza and was just about to leave when Cindy asked if she could catch a ride as she wanted to get a couple of things in town.No problem I thought so of we go as we are driving Cindy starts talking about how Greg has been having back problems and how hard it has been on there marriage.I sympathised with Cindy and told her that hopefully Greg’s back will get better and things will get back to normal.Then out of nowhere she starts to cry and asks me to pull over and park at a rest area close by.No problem I thought and pulled over.Then out of nowhere Cindy asked if I thought she looked sexy.I mumbled that I did think she was still good looking not wanting to upset her anymore and hoping she would start to feel better.Then she stunned me and lent over and kissed me long and wet and started to rub my hardening cock.I grabbed her tits which were big and plump and squeezed them hard.Cindy let out a whimper as I fondled and squeezed her nipples.By this stage I’m fully erect and Cindy is kissing me hard and rubbing my hard on.Then all of a sudden she stops and I freeze thinking she’s come to her senses and that will be the end of it.But to my surprise she unzips my fly and takes out my hard swollen cock.When she takes my cock out she gasps and says that my cock is the biggest cock she’s ever seen.I must admit that I’m 8 inches and thick and cut.Cindy goes straight onto my head licking and tasting my pre cum and then taking as much into her mouth as she can.I’m so turned and reach under her dress to feel her pussy and to my surprise she’s not wearing any panties.Her pussy is drenched and I start fingering her all the while she is gobbling down my cock.Cindy stops sucking me and jumps into the back seat and orders me to get over here and ram that monster cock into her pussy.I climb into the back seat and without taking off my shorts I flop my cock out and enter Cindy,she moans and starts grinding into me and I just ram my swollen cock all the way to the hilt.And fuck me I had only pumped her 4 or 5 deep strokes then gushed into her pussy.Cindy then started to shake and then screamed that she was coming too.I was still hard and kept pumping her pussy which was feeling sloppy with both our cum juices then to my surprise she took my cock out of her pussy and lined me up to her enter her arsehole.Well fuck me I entered the tightest hole ever and just pumped her hard and fast then shot another load into her arsehole.Cindy came a second time and was shaking and panting and grinding back into me even harder than before.Gosh we were both spent and a bit disheveled as we lay in the back seat of the car.After about 5 minutes we straightened ourselves out as best we could and drove to a petrol station to use the toilets to freshen up and try and get rid of the cum smell on ourselves.After picking up the pizzas,on the way home Cindy thanked me for what happened and promised that this would be our little secret.
