My wife Lynn was always so shy sexually,didn't really even like to have sex during the day or with the lights on,said she didn't have any fantasies. Even when I told her one of mine was to watch her with other men,she showed absolutely no interest in it.All in all very straight-laced and ultra-conservative when it came to sex,or so I thought. My wife is a 26 year old pretty little spanish girl,petite 5' 2" tall and weighs about 120,with a great set of C size tits,and a pair of legs and an ass on her that was made for sin.Long raven hair,and gorgeous dark spanish eyes and full but not over-full pouty lips. We had been married about 2 years when my uncle went into the hospital for what we thought at the time would be the last time.My mom was so upset on the phone that I decided i better go there if for nothing else than to comfort her. Money was a bit tight,so i told my wife only I was going,and I'd have to drive as i couldn't afford a plane ticket,and then I packed a few things and hit the road on what I thought was going to be a very long 1,500 mile journey. About 300 miles into the trip my cellphone rang,my mom telling me nevermind,turns out uncle just had a pulled muscle that cause him chest pain and the doctor had released him with a clean bill of health. It was almost midnight at this point,and I didn't want to call and disturb my wifes sleep,so i just turned the car around and headed back thinking if i could keep myself awake and moving I should be back home by 5am. I only stopped once to fuel up and get coffee and made it home by 5 am like I expected,only to find a pick up truck parked in my driveway.I pulled in right behind it and headed for the door,through the sidelight I could see most of the house was dark,except for the bathroom light in the hall. I quietly let myself in and headed for my bedroom noticing along the way a trail of clothes leading from the living room and down the hall,women and MENS clothes. Immediately I was pissed off and for a second , thought of rushing into my bedroom to see what the fuck was going on. But curiosity and I must admit arousal got the better of me,so i quietly crept down the hall.As I approached our bedroom,I could hear the unmistakeable sounds of my wife moaning,and also the sound of flesh slapping flesh,my heart was going like a jackhammer as I peered through the not fully closed door. What I saw was so erotic,she was riding someone,i couldn't see his face,but I could clearly see a very large cock goin in and out of her pussy she would lift slowly up then all the way down again so you couldn't see all of it,but when she was at the top of her ascent there were a good 8 inches still outside,and thick? The thing must have been 2" wide,her pussy lips were splayed so far apart i was wondering how she wasn't split and bleeding. My cock was so hard watching this,I slowly unzipped and pulled it,and was pulling on it to match him stroke for stroke,when suddenly she slid off of him and got on all fours,he got up behind her,that's when I saw who it was,one of her ex's Howard,his dick was every bit of 10"s long and thick,much longer than the 6" average thick one i was pulling on now.He shoved it into her all in one stroke,and she started talking nasty to him while he fucked her hard, "Yes Baby,fuck me Howie,so much better than my husbands dick,so much bigger,it feels so fucking good" to which Howard replied," Yeah baby I know you love it,I'll give it to you anytime you want it,just like always". I couldn't believe my ears ,"like always"?? What did that mean,I didn't have to wait long to find out,my wife said "You know I'd like it more often but there's only so many times I can sneak out of the house,or when he's not here,so I'm afraid once or twice a week is all it can be,just like it has been for the last 2 years" I couldn't believe my ears,but I also couldn't stop jerking off watching them fuck,it was so exciting,she was cummming so much,way more than she ever did with me.Finally I could take it no more and sprayed cum into my handkerchief a very big load,wow i must have been turned on.I quietly crept out and drove away,coming back at noon(after calling her at 8am and telling her i was coming back). She acted as if nothing happened,of course she had 2 years worth of lying and cheating practice before this.But I didn't mention a word about what i've seen,and since then i've seen her fuck 10 different men,on many,many occasions,but those stories will have to wait.
