My Slut Wife

My name is Charles and my wife Julie and I have been married for over 20 years. Our sex life has been great all along and both us have very high sex drives. Julie is wet all the time as she is a very horny woman and is insatiable as far as sex is concerned . She is multi-orgasmic and can cum numerous times before I explode into her willing cunt. She loves to wear very revealing clothes mostly without a bra and a panty underneath.
One day I came home early from work as I was not feeling too well. As I was about to enter the master bedroom I heard some sounds coming out from the guest room. As I was walking toward the room I could hear groans and moans of a woman. The door of the room was wide open and I was shocked at what I saw.
There on the bed was my wife with her legs spread wide open and fully naked with a man on top of her and his cock impaled deep into her wet pussy ! I could see his cock going in and out of her wet pussy and she was moving her hips up and down in unision with his movements. The sound of wet liquid and her groans and moans filled the room as her lover fucked her. Her arms were around his body pulling him close to her. Her body was visibly trembling with illicit lust with this man.
I was angry at first and then to my surprise I found myself aroused at the sight of my wife having sex with another man and enjoying it. My cock was hard and I found myself stroking my cock as I watched my adulterous wife giving herself to another man. My cock was hard and real slimy with precum!

Meanwhile Julie and her lover were wild on the bed clinging to each other and uttering obscenities as they got high in sexual ecstacy. Her lover pounded and rammed her wet cunt with his hard cock and she moaned and groaned with every deep penetration. Her legs were wrapped around her lover's waist as she ground her groin against his in sexual pleasure. Their breathing was loud and fast and then she cried out , " Fuck me.....fuck ..... cum into me now !" Her lover grunted and I could see his body tensed up as he exploded into her. Julie cummed together with him and she screamed like a mad woman when his seeds entered her womb. Then there was silence as she lay on top of her motionless and she with her legs wide open . I could see her lover's cum leaking out from the side of her fucked cunt.
This was the first time I ever saw and watch another fuck my wife and many more was to follow in weeks to come. I thoroughly enjoyed the sight of my wife being fucked by another man and I want her to continue with her new-found pleasure.
