I have always fantasised about seeing my lovely wife Kerry having her big bottom soundly punished by a strict older man. We are a couple in our 30's and Kerry is very attractive with black hair and brown eyes her figure is very womanly to say the least with biggish boobs and full hips that surmount her broad beam. I have made no secret of my fantasy and Kerry has always laughed it off. But to my gobsmacked surprise she recently said o.k. and that it seemed harmless enough if there was nothing more involved than 'giving some kinky old sod a thrill'. I found Mr Simpson through a swinging site he was local and had a keen interest in administering correction to young wives at 67 years old he fitted the bill and i told Kerry and it was agreed we meet! We first met Mr S at a public house in town and he seemed such a nice old gent putting Kerry well at ease. Kerry had chosen to wear a pair of beige trousers that day that hugged her bottom tightly and left little to the imagination in so far as the outline of her knickers was concerned (if i remember correctly she wore caramel coloured full backed ones that day). Mr S smiled at me as he watched my wife's bum as she walked to the ladies. 'Hee Hee Peter you've certainly come to the right man if you want to see that lovely backside get put through it's paces'. The old gent talked more about himself and told us of how it was not unusual for him to perhaps spank as many as two bums a week! We agreed a date next thursday at our house. Kerry was a bag of nerves as the hour came 'the things i do for you' she giggled. Kerry had again opted for wearing a blouse and trousers grey this time but as tight beneath she wore tight mauve panties (i remember this time with good reason). Mr S arrived in due course carrying a small case that i saw Kerry view with trepidation. After a cup of tea Mr S announced. 'Well let's get down to buisiness i hear you have been a bit of a naughty girl Kerry?' It was said with authority and Kerry giggled nervously. 'Peter has asked me to spank your bottom young lady and i intend to do so'. Mr S put his hand on Kerry's knee. 'O.k.' she said meekly. My heart raced as he explained to my poor wife how he intended to use a tawse and a cane on her backside. Kerry was ordered to stand and she gasped in shock as Mr S audaciously fondled her ample rump 'Naughty girls need smacked bottoms Kerry' he said. 'Now go to the middle of the room bend over and touch your toes'. Kerry's magnificent arse faced me as she did so and Mr S took position and delivered about 20 hard smacks. Kerry yelped and her bum wobbled it was a very arousing sight. Kerry was again invited to sit as Mr S showed us the contents of the bag-a tawse and a fierce looking cane. Kerry looked dismayed. I smiled sympathetically but i longed to see it welt her buttocks. Mr S instructed Kerry to leave the room and return minus her trousers. Kerry complied and returned in her blouse and little knickers. Mr S was clearly moved by the delightful sight of my wifes dark bush beneath the thin cotton and the way it barely contained her vulnerable big bum. He quickly got down to the matter of applying the tawse to her knickered rump as my wife stood hands on knees bottom pushed out. It really must have stung and Kerry shrieked and pleaded...to no avail. After 10 with that dreadful implement Mr S allowed her to stand and rub her smarting cheeks. When she turned she was confronted with Mr S flexing the cane. 'Bend over and touch your toes Kerry' he boomed. I felt like intervening when he took down Kerry's knickers and again fondled her bum. He had a clear view of her pussy i'm sure. I sat and watched enchanted though as he applied 6 of the best to Kerry's stinging buttocks. Kerry was told to stand in the corner and as Mr S and i looked at her tramlined bum Mr S advised me to massage it with cold cream. Well i did so and at least Kerry enjoyed that part which took place after Mr S's departure. Kerry has not agreed to a repeat and i respect that now my curiousity has been sated.
