My name is Mike I'm 48 and after my marriage broke up my older brother John and his wife Caroline invited me to stay with them until i sorted myself out. John is 55 and his wife Caroline is 53. There kids have flown the nest and they have a large 4 bed detached house . My brother is very outgoing and a bit of an extrovert while I am quite I am little shy! I tried to not intrude on John & Caroline and usually went to bed early but often was woken by the sound of the two of them having sex.. Caroline although about a size 16 keeps herself in shape with her aerobics classes and was still a very attractive .busty short dark haired brunette . A couple of months ago on a Saturday night on the May bank holiday I came back from the pub a little drunk and quietly crept in so as not to disturb anyone ! as I climbed the stairs I could hear them having loud sex ! As I passed their bedroom door I noticed the door slightly ajar and peeped in to see Caroline on all fours on the bed giveing my brother a blow job. After she had finished she moved around to offer her pussy to John . She had a lovely shaven pussy and a curvy bottom I watched my brother tease her with his cock before shoving it in and slowly trusting before building up a rhythm . I watches with my cock in my hand as Caroline's large boobs swayed as John pounded her ! Both they moans of pleasure grew louder as they were obviously about to cum . Caroline urged him to fill her ! My brother obviously did as he was told and Caroline let out a string of expletives ! I was time for me to creep back to my bedroom so as not to be discovered. . The next morning was Sunday and I was woken by the sound of Caroline singing in the shower and after I showering I went to get breakfast. Caroline was already cooking breakfast for us all. She was simply wearing a dressing gown which outlined her curves. I offered to help but she. told me to take a seat . John joined us and he was in a jovial mood. He asked if I had a good night at the pub and said he didn't hear me come in? I smiled and said I think you were otherwise occupied . He grinned and said to Caroline your moaning was keeping Mike awake last night ! She blushed and said sorry Mike if we disturbed you ? That horny old goat wants it every night. John said we need to find Mike some pussy ! How about your friend Sarah ? I bet she is a great fuck? Caroline playfully hit John with the tea towel and said that's my friend your talking about ! My brother simply said I mean it as a compliment just like I tell you your a great fuck . She hit John again with the tea towel and called him a dirty dog but had a smile on her face. I invited them for a pub lunch as my treat ! and a few hours later and pleasant walk we arrived at a pub about half a mile away that was recommended for their food. We all enjoyed the lunch and the several drinks that followed . After returning home a little merry John announced as it was a bank holiday tomorrow we might as well continue enjoying the evening . He opened up a bottle of wine which was followed by another . We were all rather inebriated by about 10pm Caroline and John were stroking each other legs I made my excuses and said I was tired and went to my bedroom. I was flicking through a readers wife magazine and stroking my dick when I heard John -and Caroline come up stairs . There was loads of giggling and my brother telling Caroline to move quiet! After about 10 minutes I heard a slapping sound My curiosity got the better of me so I crept out to their bedroom door. The door was again slightly ajar but nor as much as previously . I saw Caroline was handcuffed to the bed naket and my brother was spanking her with a leather paddle . She was obviously enjoying it by her moans . I was outside the door stroking my cock when John announced I need a pee and opened the bedroom door and caught me with my dick in my hand ! I was shocked , but he simply laughed and said no point standing there brother you might as well take over from me while I have a pee as he handed me the spanking paddle . Caroline looked around in surprise but she didn't say a word . I was standing there in front of my brothers naked handcuffed wife with a spanking paddle in my hands. What else could I do I thought but do as he said and continued using the paddle of Caroline bottom . The sight of her swollen bare pussy give me a raging hard on ! I soanked her gently and she moaned . My brother returned and unlocked her handcuffs . And said come on darling you got two horny men here to take care off. John took out his cock and beckoned for me to do the same ! Mine sprang into life ! Caroline turned around and grabbed both our cocks and started go stroke them. She then took it in turn to suck both of us in turn and then together . Her tits bounced as she sucked . I came in her mouth first followed by my brother and she swallowed our cum . She expertly worked on our cocks and soon had us hard again . She then turned around and offered her pussy to us. I let my brother go first but soon it was my turn while John moved to the front to roast her . We soon shot our loads and collapsed in our drunken state on top of the bed. I awake at about 6am to find Caroline who was in the middle stroking both our cocks . This enviably ended with us both fucking Caroline again. When I woke next at about 9am Caroline & John had already showered and was down stairs in the kitchen. When I showered and arrived in the kitchen they both greeted me as if nothing had happened . Caroline served a cooked breakfast and said you boys need to keep your strength up if your going to keep me happy and give a naught wink . Most weekends after that we share Caroline and although I have now got my own place I still return occasionally . The end so far ?
