My story goes back to the early 1990's when I was in my early 20's,it is true to say that I had always been more than a little interested in the whole subject of spanking and corporal punishment and that around that time I had discovered magazines on the subject (this was of course the pre internet era),I had imagined myself as the strict disciplinarian, spanking and caning the bottoms of the erring young ladies within the pages,but increasingly and much to my consternation I found myself fantasising from the other perspective,imagining my own smooth young bottom bared for punishment by a strict and much older gentleman. One of the publications I used to sometimes buy at this time was basically a contact mag,and one ad made me stop in my tracks as I read it,I forget the exact wording,but it went something like "Mature and considerate disciplinarian offers correction to adult schoolboys". That's not verbatim,but it's not far off. Anyway I found myself thrilling to the thought,and I went as far as to listen to the voice message at the number printed below the ad,the voice I heard sounded rather like some doddery old gent,a bit like the absent minded professor type and I put his age at about 70 if he was a day...This proved in fact to be accurate. The message itself was rather wordy as the old duffer described his interests and waxed lyrical about his strong belief in the benefits of strict discipline. It was with a sense of great trepidation and mild anxiety that I eventually plucked up courage to respond to the ad. Needless to say I was a bundle of nerves when I checked my own mail box, that I'd had to set up, to see if he had responded. Well indeed he had,the gentleman who I was to become known to me as Mr P and later Geoffery responded with lots of questions regarding my age,weight,height and the colour of my hair,also he spoke very lovingly of his interest in tight fitting traditional underwear. I don't know how I ever made that first meeting,but I made the trip to a small country pub that was not far from where I lived (I had said that I was reluctant to travel too far to meet him and he was very understanding on that point,even though in truth he lived no more than 20 miles away). Mr P seemed absolutely delighted to see me,and I'd dressed casually but smartly in a manner in which I thought he'd approve. Mr P awed me a little,he was certainly very affable,with a mop of slightly unkempt white hair,he had a thick set strong physique (I am slim and slight),and he spoke with great authority with a resonant voice,although always very friendly and good humoured.Mr P was in fact 72 years young and very robust. It thrilled me no end how he seemed to have a natural command of the situation from the very outset. It seemed to me that Mr P had a complete understanding of my submissive fantasies and he explained elements of my own personality to me and also enquired as to any experiences of spanking I had had (I had not of course). By the end of that first meet I felt very comfortable with my would be mentor,if a little over awed. Well before we left Mr P asked my measurements as he said he wanted to buy me a little something for our next meeting which he hoped would be at his home,in the car park as I left him Mr P very cheekily groped my bottom as I walked away and said he looked forward to next week. I did not drive at the time so Mr P came and got me from the same pub (this was to become the usual arrangement). At his very nice little cottage home with it's big garden,Mr P gave me a package and asked me to go upstairs and put them on,he smiled benignly as I took the package with shaking hands,and babbled something nervously. "It's a lovely day,let us have tea in the garden when you return" he said. The package dear reader contained a pair of tight white jockey type pants that barely fitted my bum,a little vest,and a pair of very lightweight white shorts that were so short they barely covered my bumcheeks,they were ridiculous,but at the same time I felt a thrill knowing Mr P would be looking at my bottom lecherously.Needless to say he was agog when I returned and we sat in his garden at the little table with the parasol and drank tea from a dainty little tea service. Mr P put his hand on my knee and thigh as he chatted away happily about fresh air and sunshine. Then just as I was least expecting it he told me to stand up and run around the garden,from his seat he had me perform all manner of physical excersises,including running on the spot,as the tight shorts seemed to be threatening to split under the strain of my flexing buttocks. Suddenly Mr P told me to stop still and touch my toes,I felt very vulnerable with the tight shorts drum tight over my barely covered cheeks,Mr P strode over and sent a thrill racing through me as his big strong hand stroked my bottom,next there was a flash of burning pain as his hand rose and fell very hard on each of my burning cheeks in turn,the spanking went on for some time as he soundly punished my bottom as I bent over in the spring sunshine in the secluded garden. From that day on my bottom was presented regularly ,for spanking,including the strap and the old fashioned crook handled cane,most often in Mr P's study. Most shameful to admit (yet remember),is what else occurred that afternoon and on later occasions,I say shameful,as I have always thought of myself as straight,but I submitted to more than a spanking. After the first spanking in the garden MrP insisted I go lay down on my front on the bed in his guest room,he followed me up,and gently removed my shorts and pants to apply some cooling cream to my burning bottom,I must admit I found the massage very relaxing,and I enjoyed the feeling of the big hands kneading my pert nates,I don't know how I let what happened next to occur,all I can say is MrP understood more about my deep seated submissiveness than I was ready to admit to myself. I remember he stopped and wiped his hands on the kitchen roll he brought in,and I was vagually aware of a small jar of Vaseline being taken from the bedside cabinet,next I remember a thick bony finger teasing around my anus and then going in quite deep. The sensations came as if in a dream and I felt relaxed,it was not until I heard Mr P tell me in a soft low voice to get up onto my knees that I stirred and looked anxiously around. I wished I had not! Mr P had taken off his trousers and pants,he stood there with his fully erect and very big penis on display from beneath his shirt,I panicked inwardly,and he seemed to sense this,he spoke reassuringly and softly,telling me to relax and telling me I was going to like what he was going to do. But his penis was so impossibly thick,the big purple glans was huge in it's own right,I was excited but scared. Next thing I knew the wicked old lecher had his big heart shaped glans positioned at my tingling young anus. Yes before I knew it my poor little arsehole was being fucked slowly and deeply by his thick length. It was an incredible sensation to feel my mentors hot seed splashing in great spurts in my rectum. And yes it happened again after that,many times.
