Caught spanking Jenny's bottom at the seaside

In one of my first posts I mentioned Jenny a sexy plump civil servant who was always up for a good hard caning followed by sex. Jenny stayed with me several times and we always made a point of going out shopping looking for school uniform items for her to present her bottom in. Jenny dressed smartly for our meetings, always a tight business skirt, high heels, proper stockings or stay-ups, and a thong, she reserved the big knickers for the school scenes we did.

During one of of our early meetings Jenny talked about shaving her fanny for the first time, so it was off to a local supermarket for some suitable razors, then the fun job of attending to her pubes until all was smooth. From then on she kept her bits super smooth. It was around then that she also wanted to give anal a go, so after a good caning to get her aroused we set to. I had a vintage glass pestle (as in mortar and pestle), with knob like ends, one big and one small. With some lube and some careful work with both ends of the pestle I was able to relax her bum enough to slide my cock in, Jenny loved it. Happy memories!

On one of Jenny's visits we headed down to the coast for a meal. It was a warm summer night so after eating we walked along the promenade, me teasing her chubby, shapely bottom with the odd smack. It never took Jenny long to get going and soon she was suggesting that she deserved a proper spanking. I guess it was around 9 at night, so getting dark, but still this was a public promenade with little privacy. Wandering on we found a neat little garden right next to the promenade, it might have had a bandstand in it. It was surrounded by well kept hedges just high enough to give some cover. Inside the garden we found a bench seat, itself screened by some hedging. This appeared to be the ideal spot. Seated I lifted Jenny's skirt and pulled her over my knees. Jenny had her normal stockings and thong on, so all of her chubby buttocks were on display. Jenny was the sort of woman who wanted a good hard spanking (or caning or slippering), no weak taps on her globes, so I set to walloping her plump rear until it was red. Neither of us thought at the time that spanking her big fat buttocks was a noisy business! Concentrating closely on this task I was aware that someone had walked into the garden until she actually walked right past us! As I looked up I caught the amused look and quick laugh of a woman, she looked like a well to do lady in her 50s or 60s. She must have had Jenny's spanking, and more or less nude buttocks, in view for a good ten seconds or more, and of course she heard it. She could have taken a different route out of the garden, but she had marched on right past us, probably less embarrassed than we were. I gave Jenny's backside a few more slaps and we then both decided it was time to head for my house for some privacy. Back home her smarting rear end received a thorough caning, before she lay back, legs apart, pussy sopping wet, for some attention of a different nature. And all the time me thinking of the mature woman in the garden and her laugh.

I've added this image, it's not of Jenny but her bottom is very similar in shape.
