My wife of 25 years was lying naked on the bed with two total strangers - hands all over her body - three pairs of legs entwined.I stood watching almost unable to breath with the excitement watching my innocent wife submit to deeply hidden animal desires yet feeling a strange mixture of jealousy and inadequacy knowing that I had never made her feel this good in 25 years of marriage and that I probably never would in the future. Rewind ten hours.To celebrate our Silver Wedding I had booked the best hotel in Glasgow - no expense spared.We shopped in town until about 4pm buying each other gifts.A silver bracelet for Caroline who in turn bought me an expensive and rare 25 year old malt whisky.Caroline is 49 - quite small - large breasts - a little bit over weight having given birth to our three teenage kids and certainly not as glamorous as some of the other wifes described on here. Sex has always been ok - but recently dwindled to only once a month and actually before going away we hadn't done anything for over two months so I was really hoping that a nice hotel , nice food and nice wine would help rekindle the fire.We have never strayed and were virgins when we married. After we had showered and dressed we made our way down to the bar for some pre-dinner drinks.Caroline looked amazing in a low cut black dress which showed off her fullsome breasts and also exposed a glimpse of her red bra.She also smelled fantastic wearing a new perfume purchased that day.After a couple of glasses of wine we made our way to the restaurant which was quite small and we found ourselves sitting quite close to the table next to us which at that time was empty.Mid-way through our starters I was aware of the table next to us being filled ; two guys both American. The food was out of this world and we were on to our second bottle of wine before ordering dessert.I was really looking forward to getting Caroline upstairs. The Americans next to us were talking about golf and one of them asked me if I could recommend any courses nearby.We started chatting and they introduced themselves as Tom and Steve - both in their mid thirties typically nice looking,blonde healthy white toothed Californians and in Scotland for a golf and whisky tour.They were both good company and we all continued talking over coffees and liqueurs with Caroline mentioning the bottle of rare malt she had bought for our anniversary.They were very impressed and I suggested that if they could smuggle some glasses out of the restaurant we could all have a glass in our room. We made our way in good spirits to our room with Caroline giggling at the thought of three grown men stealing glasses and scaring our new American friends into thinking that if they got caught they would be spending the night in a Glasgow jail. Tom ,Steve and Caroline sat on the sofa in our room as I opened the bottle of malt and poured us all a glass.I knew that Caroline was becoming increasingly drunk as she laughed ever louder at anything Tom and Steve said.She was flirting with them and they knew it.She asked if they were married-turned out they were both recently divorced.''Divorced and desparate'' said Steve.Caroline laughed again and placed her hand as if in consolation on Steve's knee. Steve then held her hand and began stroking her wrist asking if all Scottish girls were as nice as her.Caroline just giggled again and for the first time I wondered just how far things could possibly go.There was suddenly an air of tension in the room and for the first time there was an awkward silence.It was as if I was in a dream - Tom broke the silence by saying I was a very lucky guy to have had such a beautiful wife for 25 years - placing his hand on Caroline's knee as he did so.She made no effort to remove it. Steve then moved his hand to her other knee and Caroline just smiled and closed her eyes. Both Tom and Steve looked at me for reassurance...I just nodded my consent...as I was lost in a fog of drink and excitement. Steve moved in and kissed Caroline gently on her neck.Tom continued rubbing her knee and moved his hand higher.All the while Caroline kept her eyes closed even when Tom's hand moved under her dress towards her pants.Steve was slowly unbuttoning her black dress - slowly as though scared not to break the spell she was under. ''Think it would be better on the bed'' whispered Caroline as they all moved as one to our large double bed.Her dress was removed quickly leaving her in red bra and pants.Tom and Steve took off their clothes and lay down either side of her.Their cocks were larger than mine.Caroline herself removed her bra as Steve pulled down her panties.I could not believe what was happening.Carolines large breasts were being mauled by them both and Steves thick hard rigid cock was pressing against the soft folds of Carolines belly.''Oh God honey you are so hot'' said Tom as he began to finger her by now soaking cunt.I was shaking with excitement watching Steve sucking at her breasts.Caroline was moaning now - a low deep moan I had never heard from her before...as though all her inhibitions were gone and her natural animal desires were being released. ''Fuck me please'' she said to no-one in particular.Steve moved on top of her and I moved in to watch as his pre-cum dripped on to her thigh and then as the tip of his massive cock pressed gently at her hairy cunt.Caroline turned to me and for the first time looked straight at me ''Kiss me'' she said.Her mouth was watery and wet and she gasped into my mouth as Steve began thrusting deeper into her.I have never loved her so much as then.Our tongues danced but she had to break away as she began panting harder as Steve thrust deeper. Tom then moved to her side and offered his cock to her.She began wanking him them moved to lick the tip and down his shaft to his balls...and back to the tip before taking him into her mouth. I moved behind Steve for a better view and could see Caroline's white cum on his cock as he came out and pushed back in.Caroline was moaning louder now.I began rubbing her arse using some of the juices from her cunt to rub on her rosebud arsehole.She had Tom in her mouth and Steve in her cunt as I pushed a middle finger slowly into her anus. We were all in a frenzy by now.Further and further I pushed - feeling Steve's cock deep in her cunt - feeling him thrusting faster as I too pushed harder.''Oh fuck yes...oh fuck yes...you dirty bastards..'' she screamed ..I looked down to see Tom's come spray all over her hair and face..Steve then came with aloud scream right up her unprotected cunt as her tight arsehole held on to my middle finger. Tom began wiping his cock all over Carolines face - she lapped at his balls and then down - down further to his arse.This was incredible.I was still fingering her arse...Steve had moved off ..and Caroline's tongue was now pressing at Tom's anus..pushing deeper and deeper.'God she is like a bitch on heat' said Steve...as he carelessly massaged her 49 year old breasts. Soon Tom was hard again and Caroline moved to mount him.As she did so she whispered to me ''Fuck my arse''.It was awkward at first on account of Tom's size but soon we were both fucking her.She was screaming now - her body was red hot and she was red faced and sweating.Steve offered his cock and the threeway was complete.I only lasted seconds but when I came up her arse it was with the most intense eruption I have ever had. When it was over Caroline lay naked on the bed with wet stains all around and the smell of sex and perfume in the air.She asked for a bottle of water to cool down.Tom and Steve got dressed and kissed and thanked Caroline for a never to be forgotten night. I lay beside her and we hugged - amazed at what had just happened.Deep down I knew I could never release such desires on my own...but glad that at least she had experienced them...and for that she thanked me dearly.
