My wife Kate and I are both in our early 40's and for some time now we have been experimenting with spanking and corporal punishment with Kate taking the submissive role.For my part It's a subject that has always interested me,Kates interest has been fired by a certain best selling book that came out a couple of years ago,I'm sure you know the one I mean. A typical scenario would invole Kate going over my knee for a bottom spanking,followed by a slippering on her bare buttocks. Exciting though our games were they did not quite meet our expectations,perhaps we know each other far too well,Kate for example would never be able to really see me as being quite the strict disciplinarian,and likewise I cannot fully take myself seriously in this role.It is a dilemma we have discussed and recently we have found a solution that satisfies us both and has had an astonishing effect on our relationship. It was I that first suggested the idea of finding a new spanker for Kate,an outsider,somebody who would tick the right boxes so to speak with regards to creating the very discipline scenario we hoped to achieve. Well Kate was sceptical to say the least,and voiced her concerns on that score,but I assured her that I shared those concerns and that I was not proposing that we looked for the first Tom,Dick,or Harry, that came along. Kate is a very attractive dark haired woman, at 43 she has a fine figure,a little rubenesque as one might expect,with full boobs and most importantly a nice big peachy bum,I certainly did not imagine any problems at all in finding a would be suitor so to speak,but who? I would have to get this right first time. Having discussed it further with Kate we decided that if this was going to happen at all the third party would need to be 1.Well educated. 2.Well spoken and charming. 3.A professional. 4.Considerably older than us. These provisions were all Kates,and I have to say that she was wholly correct in making them. Well I spent a long time looking at spanking contacts sites before I found the ad that caught my eye,it read. "Gentlemen,are your wives/lady friends in need of traditional discipline? If so contact me,a mature disciplinarian with many years of experience in old fashioned methods of correction." There was a photo too of a rather doddery looking, bespectacled old chap who gave his age as being .."septugenarian". Kate took an interest too,and I posted a message to his inbox explaining the situation,within the hour I had a long reply that certainly seemed to prove that this man was our guy. The message he sent managed to be both formal and friendly at the same time,he said he fully understood our situation,that he'd heard of such "inexpert domestic discipline arrangements" many times before and that he had remedied the situation to the satisfaction of all involved. He asked about our relationship,and about Kate and her interest in spanking,saying he looked forward to meeting her. We continued like this,sending messages back and forth,for about two weeks until we were 100% sure we wanted to go ahead with it,in that time we sent a few pics of Kate to the old chap,nothing revealing,just some nice ones of Kate wearing a nice frock in the garden on a summers afternoon. Kate had by now began messaging our would be mentor on line,and it gave me a frisson of excitement to read their exchanges. Kate was opening up to the man she would come to refer to as Mr'P' in a way she never had with me,he seemed to understand her submissive side very well and encouraged her to discuss it quite openly,he also told Kate that he would be very likely to use a school cane on her bottom at some future point. Another thing that was discussed was if Kate felt comfortable with me present or not,we had not considered that before,but Mr P made a good case for the initial meeting to exclude me from the room (his study),because it would act as a distraction to Kate..I would of course be given a chair to sit on outside the study where the door would be closed but not locked,and I could listen in...Things were taking an unexpected direction I thought. We actually drove to Mr P's home,a lovely cottage in a village in Surrey,we found him absolutely charming,like a doddery old schoolmaster,he was in fact an academic and had lectured at university. It was a cosy cottage with all manner of books spread about the place. Kate had worn a lovely,flowery,light summer frock for the occasion,beneath which she had a white brassiere and a demure pair of white full cut knickers that looked very tight on her big bottom..What a view Mr P would have! We chatted and drank tea from a charming little tea service,Kate was nervous and giggly,but she was warming to Mr P and his soft authoritative tones. I was a tad nervous too,but Mr P took it all in his stride. "So Kate,I understand that you have never had your naughty bottom warmed properly eh?That is what your husband tells me,he says you have wisely chosen to have that situation rectified?"Mr P said unexpectedly. Kates pretty face blushed crimson to be confronted by the strange man in this way. "Well..I..err..I mean..I.." She stammered. "Yes I know what you MEAN young lady" he said in a resonant voice that brooked no discussion. With that Mr P invited my red faced wife to his little study which was the next room,I was offered a chair on which I sat outside. The rest of what happened that afternoon I only know from what I heard,and from what Kate recounted after. When the door had closed I heard the conversation resume,as Mr P asked my wife if she was ready to accept his correction,which he intended to apply to her bottom. I heard Kate gasp as Mr P opened a cupboard and showed her a collection of school canes and leather straps. Kate gave a gasp..She told me afterwards that it was not simply the sight of the spanking implements that shocked her,but the fact that Mr P had given her a cane to handle and look at and that as she was doing so he put his hand up the back of her frock and fondled her knickered bottom. Next I heard Kates pleas as she was given a good spanking,during which Mr P took down her knickers,Kate protested,but Mr P spoke to her very firmly. It was quiet for a while,but then Mr P told Kate to take off her frock and her bra and stand naked in the corner,hands on head.At this point Mr P opened the door and let me in. My cock was rock hard at the sight of my feisty wife looking so submissive and obedient with her hands on her head and her big heavy tits and hairy little cunt on full view,her knickers were completely off by now. "I thought you might like to see how naughty girls have to stand" he said smiling,Kate was flushed and red faced,but I know having the two of us ogling her curves excited her,I could tell. "Turn around Kate,show your husband what I have done to your bottom" he said loudly,and Kate wasted no time in obeying him. Kates poor bum was pink,with splotchy hand prints clearly visible,next Mr P had her touch her toes in front of us,and I whistled at the sight of my wifes glorious big arse that had been so soundly dealt with. However,I was soon out of the study again,as Mr P had scarcely begun disciplining Kate,and he used a variety of leather paddles on her buttocks as well as the cane before she emerged about half an hour later. Afterwards at home,Kate was as randy as anything the whole experience had made her feel very turned on indeed,as was I,and I listened intently to her version of the afternoons events,we made love with a passion that we had lacked for some time. Something changed that day,I no longer spank Kate,that is our elderly friends job,Kate ,I know it..And Mr P . Although I am allowed to watch the proceedings now.
