Mine was submissive lady of 49 called Helen. Her husband wanted to see her spanked, as he wasn't into it himself but enjoyed the voyeurism. She on the other-hand had always had a fantasy of letting another man spank her. She had never had a spanking, not even in childhood, but the idea of having one was strong. They owned a pub and once the pub closed after lunch (few years back now!). We went up to their apartment above the pub.
They had a nice large ottoman, enough to kneel on and also at an excellent height for me to administer her spanking. I told her to strip to her underwear, and when she did, she was men's dream. She wore a beautiful matching bra, pants and suspender belt holding up seamed stockings. She had a good figure, and I congratulated her on her underwear, and how cute her bust and backside looked in them. She thanked me and blushed a little.
I asked here is she was sure she wanted to be spanked. She quietly answered yes, so I asked her again wanting to prolong the anticipation for her, as from experience any form of play was always improved by the anticipation in the mind of the receiver.
Next I had her Neil on the ottoman, with her head down beautifully presenting her backside to me. A backside now with her pants stretched tautly across them. For me the view gave me the added pleasure of visually seeing she was excited, as she was obviously excited and her pussy had leaked a little giving her a visibly damp crotch.
I couldn't resist stroking her cheeks and letting my hand slide across the wetness at her crotch. At which she shivered. After a minute of so of enjoying my stroking, I laid the first hand spank on her left cheek. This was quickly followed by one to the right, and then I alternated four more to each cheek. After the initial shock and gasp of the first spank each following spank was followed by a moaning sigh. I left her momentarily to go to my bag, and fetch a rubber paddle I had. I told her to raise her head and stood in front of her to show the paddle, and told her I think she was going to like what was coming next.
Obviously I was very hard and this was also visible to her as i pressed against the front of my trousers. I'm sure i saw her glance at my crotch.
I told her to lower her head again. Again I left a minute or so before I applied the paddle. Telling her what a beautiful site she was with her backside adoringly inviting my administration. The paddle was around two foot long with the impact section being about eighteen inches. Ideal to warm both cheeks at once. I applied five strokes of the paddle varying the gap between each from short to long, each one depending on her reaction to the last. I was surprised at her outburst after the fourth when she shouted "another please". So the fifth came quickly with a little more power applied by me. At which she screamed a "YEssss!" and it was obvious to me she had orgasmed as she buried her head into the ottoman.
I decided to not let her settle, and instructed her to get up, take off her pants and bra and resume her position. I'd not really looked at her husband throughout so far but I glanced across and he was obviously enjoying what he was seeing and smiled suggesting he wanted me to continue.
I moved my attention back to Helen, and told her she was now going to get her first naked backside spanking, at which she sighed. I applied another five with the paddle, stopped and stroked her pussy lips and clit, no penetration by me. I did this for about five minutes or so, with her arousal obvious. Then I quickly stepped back and applied five more with the paddle. And came orgasmed again.
I let her settle for a minute or so, telling her how good she 'd been and how she came beautifully. She turned her head to me and said "Please feel me more. I'm so wet". I turned to her husband, and I again received a agreeable smile.
I wasn't going to turn this down and I spent the next five or so minutes bringing her to another moaning orgasm.
That was just the start of a wonderful afternoon, and several more visits to them before I eventually moved away and it was too far to travel. It became obvious from that afternoon that Helen loved impact play, and at the end of our relationship she was loving a riding crop applied to her clit and a light whip to her backside while she sucked me. Helen's husband did ask me once, not in her presence, if I would cane her. I explained to him that for me, the cane was not for a female and to this day I have never used a cane on a woman.
Basically you are never too old to try something!
