This is a true story that happened just over a fortnight ago.My wife Alison and I have been married for twenty years.We are both 46 and now that our two kids are teenagers we decided to celebrate our anniversary by visiting Glasgow to see a concert and stay overnight at a city centre hotel.This would be the first time away from the kids for a long time and we were both really looking forward to it.Alison is a teacher,size 14 with large tits a little bit overweight and I guess you could describe as ''mumsy''.Over the years our sex life was restricted to Saturday morning quickies before the kids awoke - always with Alison on top and certainly nothing you could describe as kinky. Over the years I did suggest spicing up our sex life either by trying a vibrator, a penis extender or even sex outdoors - but Alison dismissed them all.She had been brought up in a strict religious family and together with her responsible role as teacher this seemed to inhibit her.The only time she seemed to let go a little was when during sex I would fantasise about her having sex with another guy - the window cleaner, janitor - whoever - and when I mentioned this she did seem to get aroused more easily.However the possibility of me actually watching her have sex with someone else seemed such a remote impossiblity -given her background - that I was resolved to keeping it as a fantasy forever.She was 46 and a teacher:what chance would there be? When we arrived at the hotel and unpacked I noticed looking out the window that there were windows of three other rooms looking directly on to ours and which were only about twenty feet away.When I mentioned this to Alison she giggled and suggested we leave the curtains open after.This was very unlike her and I am sure it was the excitement of being away in a nice hotel which was making her lose some of her inhibitions.All through the concert I could think only of the promise she had made about sex in a hotel room with the curtains open. After the concert we were starving and we found ourselves in a curry house just opposite the hotel.Alison was wearing a low cut top which showed off her full bosom to best effect.It was a bit late and very busy but we managed to obtain a table - right beside a noisy hen party.All the waiters wore kilts which the hen party would try and lift at every available opportunity.Our waiter - Sabir - was about 27 quite good looking and when he delivered our food one of the girls lifted his kilt right up exposing his massive penis which dangled just inches away from Alisons face.She certainly could not have missed it and laughed when Sabir apologised and brought us a bottle of wine free by way of making it up.As he did so I am sure he was admiring Alison's tits and what's more I think she noticed also. By the time we finished our meal we were quite merry from the amount of wine we had drunk.As Alison went to the loo I asked Sabir for the bill.I really have no idea what came over me but as I paid I wrote on a note on the other side of the bill :- ''Room 208 Hotel Exp - twenty minutes - if you want to fuck my wife'' Sabir took the money and smiled when he read the note. As we left my heart was pounding as we made our way back to the hotel. Alison was merry and flirty - reminding me of her earlier promise.When we got back to the hotel Alison jumped into the shower.I looked at my watch.In 10 minutes he could be here.I wanted to have Alison in bed and ready if he did arrive.Luckily she was quick and coming out of the bathroom naked with her hair wet she took me by the hand and led me over to the window and,smiling, she opened the curtains wide.We put the bedside lights on and I quickly undressed.We lay down on top of the bed so that anyone looking out their window would see everything. ''Is this turning you on ?'' she whispered as she began kissing down my body , her arse facing the window, her heavy tits swaying as she moved down to my stomach reaching the tip of my erect cock.By now I reckoned we had 5 minutes before Sabir might arrive.The thought of this and the possibilty of being watched sent shivers down my whole body.The feelings were incredible.Alison turned round to see if anyone was watching but unfortunately the rooms were in darkness.I moved Alison down with her back on the bed and began kissing her huge milky white tits.She was really worked up now and then : 'Knock Knock Knock' ''Oh my God ''I thought ''It must be Sabir'' My mouth was dry and my heart pounding.I had no idea how Alison would react and was convinced that she would throw him out. ''Who could that be?'' she said. 'It must be room service''. Alison puuled the sheet up to cover herself and I threw on a pair of pants.When I opened the door Sabir was still in his kilt.When Alison saw who it was she turned her back to us saying nothing, lying on her left side.Sabir quickly discarded his top and kilt.He was very fit.His brown cock hung down like a horse's - I had never seen anyting as big.I took off my pants and slid onto the bed facing Alison.Her eyes were tight shut. Sabir slid on to the bed on the other side.Gently I pulled the sheet down off her shoulder.Still she kept her eyes closed. ''Is she ok with this?'' whispered Sabir.I just nodded. When he touched her shoulder she jumped slightly.His brown hand against her white skin was so erotic.My heart was pounding.This was a dream and fantasy I never thought would be realised.Not at 46.Not to my teacher wife and mother to my kids. Sabir's hand moved to cup her right breast and Alison opened her eyes staring directly into mine -almost defiantly - as if she was thinking''Bet you never thought I would allow this to happen''.She was right. Sabir began to knead and massage her milky white breasts bringing her nipple to full erection.Still she looked into my eyes.I had never felt so close to her or loved her more than I did at that moment.It was as though I was sharing her deepest most intimate feelings that she had controlled and hidden for years.There was a huge trust between both of us to allow this to happen. Slowly she rolled on to her back allowing Sabir easier access to her breasts.She hadn't even looked at him yet - still she focused on me.I could see Sabir's huge brown cock growing harder and larger and thicker.Sabirs hand moved down the fleshy folds of her white belly and began rubbing up and down the inside of her thighs.And then he touched her cunt.Again she jumped and let out a soft moan and closed her eyes.Then her right hand moved down , seeking out his huge penis, and finally her small white hand tried in vain to wrap around his girth.Slowly and gently she moved her hand up and down ;up to the tip and down to his balls.She was flushed and breathing hard.Sabir pushed one finger into her swollen and gaping labia and I could hear the squelching of her juices. All this time I was scared to touch myself or Alison - frightened that I might come too soon or break the spell she was under.As they continued to wank each other my eye was caught by a light going on in the hotel room opposite. 'Oh God -what a view they would have if they opened their curtains'' Alison was breathing heavy. 'Your wife is so hot'' whispered Sabir. Alison smiled and moved over to straddle him. As she did so the curtains in the room opposite opened and first one and then quickly another face appeared at the window.A man and woman were staring intently at the scene before them. Alison moved down the bed so that she could massage his huge cock with her massive white tits.She swung them down to his balls then up to the tip as though she was trying to squeeze out his semen.Then she put both hands on to his penis.Almost worshipping its size.Her wedding ring glistened in the light as she began to lick the tip, down the shaft and down to his balls,sucking it and licking it as if it were an extra large chocolate ice cream. The viewing couple could see everything as at last I felt confidant enough to join in.Alison gasped as I moved behind her and began pushing my tongue into her sodden cunt.Reaching up I prized her buttocks apart and - another new experience-began licking around her exposed bum hole. I felt Alison move forward as she reached down , holding Sabir's monster and guided it to the entrance of her cunt.I moved round quickly as I wanted to see her face as she was entered by another man for the first time in twenty years of marriage. 'Oh God ,it is so big''she whispered to herself. ''Please , please gently' As she slid down her face was contorted in the pain of pleasure,biting her bottom lip,panting with quick breaths, sweat on her face and tits.I wanted to be a part of this so I knelt in closer offering my cock to her mouth and she greedily sucked. Sabir was now mauling her tits,roughly pulling on them , massaging them as they turned red raw with the attention.Up and down she took more and more until Sabir filled her to the hilt.We began to move in rhythm - me fucking her mouth , Sabir ramming up into her cunt.Alisons's hand snaked round and began pulling my arse closer and then she pushed her middle finger into my anus.As Sabirs thrust grew more frantic she screamed ''Don't stop,please dont stop'' I slipped out her mouth and move behind for a close up view.His huge cock was stretching her to the full.I rubbed my middle finger in her juices and slowly slipped it into her rosebud bum hole.First one knuckle.Then two.Then all the way in.I could feel the contours of Sabir's cock through her silky membrane. Again she moaned loudly. ''You dirty bitch - you are loving this'' ''Oh God yes , oh god oh yes'' We were all moaning now.I took out my finger and placed my cock at the entrance to her bum.I might never have the chance again,I thought. I began pushing in slowly. ''No Please no'' She screamed.But I was already slipping in.First one inch.The two.Then all the way in to her virgin silky hot arse. Sabir and I worked in unison ,fucking her as a team. ''Oh God Yes.Fuck me you bastards.Fuck my arse.That is so good.Please oh please'' She bucked and writhed like a beast possesd and arched her back.The smell of sex and sweat and spices filled the room. I moved my hands to massage her massive tits which were swinging forward and back , left and right with each new thrust.I turned to see the couple at the window still watching. 'Alison, we have an audience'' This is what tipped her over the edge. She screamed the loudest scream and shuddered so hard I thought she was going to pass out.Her orgasm was so intense she peed and could not stop. Sabir shouted 'Im coming Im coming'' and I came at the same time-exploding and gushing huge amounts of semen into her cunt and arse. We collapsed on the bed.Alison turned to look out the window.The couple were still watching;they waved,closed the curtains and turned out the light. ''Wonder what they are up to'' I said. Alison had a huge satisfied smile on her face as she lay between us her hand idly playing with Sabir's semi flaccid cock and balls,then down around to his arse. ''Oh yes you filthy bitch'' Sabir murmered as she pushed her finger into his arse hole,staring into my eyes as she did so.She was insatiable. Then there was a knock at the door.I thought it must be someone complaining about the noise. I put on some pants and opened the door slightly. It was the couple from the other room. ''Mind if we join you?''
