It was our usual family two week summer holiday in Spain myself, wife and two kids, we are what you would probably describe as an average family in our fortes, kids taking all our time and my wife and I growing apart with no time for each other, sex was down to once every few months. Sex has never really been my wife's thing just going through the motions in the early years of marriage to have kids and keep me happy. We were staying at this holiday complex with apartments in the grounds of hotel and a big pool in the center, with a pool bar which was open until seven o'clock, the Spanish bar men were the usual full of banter for the women chatting to each other in Spanish every time a women went to the bar and i noticed my wife giggling when she was at the bar, when she came back over to the sun beds i asked her what he had said she said he asked me if i wanted sex on the beach meaning the cocktail a bit shocked I said what did you say and she said I said yes please. On the third day i noticed the wife was drinking a little more than normal as it was all inclusive I think the drinks were stronger than normal also she always offered to go to the bar which is not her at all I sometimes feel as if I am her slave, as the day went on she was getting a little tipsy and I caught her looking over a the bar and getting a sly wave of one of the bar men she seemed to be openly flirting with them which was a real shock as i have never seen her like that before, the kids started to get bored and wanted to go up to the apartment so my wife suggested I take them up and get them bathed while she caught the last of the sun and read her book in peace. I got the kids and myself ready for the evening, they were busy watching the Spanish television and I thought as I could see the pool from our balcony I would nip down and get a pint before the bar closed at seven as I got to the pool I could see my wife's towel and book on the bed but no sign of her I thought she must have gone to the toilet as I approached the bar the shutters were down so I thought they had shut a little early then I heard a noise and thought the bar men must be clearing up in the back, there was a side door which was slightly ajar and I thought I will ask for a pint. As I walked up to the door I could hear more clearly the noise and I thought that is a someone getting fucked, my eyes became more adjusted to the darkness and could see a women bent over a bar stool the younger of the two bar men was banging the arse of this women while she was sucking on the older bar man's large thick cock. Then it hit me I recognized the bikini on the floor this was my wife getting fucked in front of me I had this wave of anger then realized I had the hardest boner I have had in years my wife was now screaming with pleasure the young bar man started saying come come and he then pulled out and shot over my wife's bum and back, they then swapped places and the wife started to suck the poor lads sensitive cock dry while the other guy started to push his big cock in to her wet swollen pussy the wife was just screaming fuck fuck as he slowly penetrated her at first then picking up speed until he was just pumping her arse,, her tits were swinging ,she had to let go of the young cock just to hold on to the stool. This was just too much for me and I ran back to the apartment straight into the bathroom and wanked my cock it took about ten strokes and I shot over the sink and up the mirror, about fifteen min later the wife came back and said she was going straight for a shower I asked her if she had enjoyed that and I could see the shock in her face she didn't know what I meant and I said the evening sun, oh yes very relaxing she said. I went in to the bathroom when she was in the shower and could make out through the shower curtain she was giving herself a good clean and I thought I bet the second cock had filled her she hadn't been on the pill for years due to the lack of sex we had. That night I was awake for most of it think what should I do, should I say anything and thought I would wait until we were back home. Over the next ten days of the holiday the same thing played out each evening she would stay down for her relaxing time as she called it, the first few days I went down to the pool just before seven each time the towel was there but no wife and the bar was closed. We were home for about a week and I was sick and tired of hearing her say to everyone how much of a relaxing holiday she had had, so I said I know what you were doing on Holiday and the reaction I got was not what I had thought, she said I don't care I have spent twenty five years having what I thought was sex with you I now know what getting really fucked is like I am going to fuck anyone I want to like it of lump it and by the way I fucked seven different bar men while we were there and had anal.
