Following the COVID-19 pandemic, my wife of nearly 40 years, Susan, had to go to hospital following an accident where she slipped and broke her arm at the elbow. Lockdown procedures were still in place at the hospital and going in alone and being awake during the operation left her with crippling anxiety and the need to be out in the countryside walking. As we had little of that left locally due to the corruption of local council planners and rampant house building, she pressured me into moving to the Yorkshire Dales in preparation for my retirement. I wasn’t overly keen but would do anything for a quiet life.

Susan has a slender shapely pleasing figure with a good-sized bust and shoulder-length blonde hair that had now turned grey. Her legs were long and slender with quite large calves developed through years of walking, swimming and cycling. With a small rounded face, clear complexion, blue eyes, high cheek-bones, a prominent nose and a nice shaped mouth, she was quite pretty when we first got married. Now she has a few wrinkles and her hair is silver. I admit the spark had gone out of our marriage years ago and we really stayed together for companionship. We certainly haven’t made love for many years.

As Susan didn’t drive, we moved to a small town that had the main amenities, easy access to walks and places for her to cycle to as well as a train station to get to other nearby places. However after buying the new house I found my anticipated pension wasn’t going to be enough to live reasonably in an area like that. That meant going into semi-retirement, working part-time to try and boost my remaining pension pot. Initially I worked from home but as things picked up there was an increasing need to be in a regional office which meant commuting plus frequent stay-overs in London.

We always used to go for walks in the countryside on Saturdays, although we had to drive to places where there was any! This continued after we had moved but Susan did more on her own during the week. She also began going for long cycle rides up the hills, which was a lot more strenuous than the flat road cycling she was used to. Then she started fell walking on her own during the week. Sometimes I had to help her when she texted to say she’d got lost and used the computer to put her on the right track. It took her mind off worrying and that was for the best but I was surprised when she took up fell running! This was taking things to a whole new level as she never previously did anything that strenuous. Most days she would start off by running up and down Ingleborough, which is the second highest of the Yorkshire Three Peaks! We went there once and walked it from a lay-by. We’d used to walk 7 miles each Saturday flat walking. This was 2 miles to the top which I thought would be no problem. The first mile through a nature reserve was fine but the rest was a steep slope that was almost vertical. I had trouble walking it and Susan was getting bored waiting for me and wanted to go on ahead.

Wearing a sleeveless halter that emphasised her large firm bust, I thought Susan looked really good in it, which made me realise the benefits all this exercise was doing for her. When she turned to go, I was surprised by how much skin she was showing. At the back, the halter was basically two criss-crossed straps that came down from around the top of her shoulders and met a central horizontal band that went around her front. I was taken aback by the musculature of her long slim back which I’d never noticed before. With clearly defined shoulder blades with clear separation and other firm looking muscular shapes I was amazed but didn’t know what to say.

“Will you be OK on your own?” she turned around to ask.

“Yes, fine.”

“You seem distracted.”

Actually I was looking at her arms, noticing for the first time how trim and toned they had become, although the skin complexion hinted at her age.

“I was just thinking how all that exercise is doing you a world of good. You look great.”

“Thank you dear,” she gave me a funny look probably because I don’t usually compliment her and turned to go.

I couldn’t help staring as the tight stretchy leggings clung to a backside that was so much smaller than I remembered with tightly rounded buttocks. It also highlighted the slender shapeliness of her legs with noticeably strong swelling hamstrings at the back of her upper legs. Susan looked sensational from the rear and I couldn’t stop watching. The leggings only came to below the knees leaving the calves bare. She’d always had good calves from the exercise she did before but now they were in a completely different league. Not only were they definitely much larger and more muscular but now they were clearly defined, sinewy and shining with some kind of inner health. As I watched those the sleek hard diamonds of big calves flex and wane in constant motion as she disappeared into the distance, I realised I was just standing there with my jaw wide open, panting fast with a blooming hard-on for my wife of over 40 years! Let me tell you, I hadn’t had one of those for her for a very long time! Even before I’d got anywhere near the top, Susan approached me on her way back down and then proceeded to walk up the rest of the way with me. I was astonished by her level of fitness which put me to shame as she outpaced me. I knew I should shape up but found strenuous exercise tedious and I didn’t really have the time. I kept telling her how fabulous she looked but any attempt to feel her calves got me a funny look as though I was some kind of pervert and getting physical in the bedroom was firmly rebuffed.

A few months later she ran the Three Peaks challenge in less than a day. There was no way I could match that and gave up even thinking of trying and just let her get on with it. I’d almost put it out of my mind and accepted it as normal until when we stayed at a hotel for the wedding of one of her family. While Susan was getting into the dress she was going to wear to the reception, I saw she was wearing sheer-black nylon stockings and suspenders. Normally I just saw her legs in leggings rather than in all their glory like this.

“PHROAR! You look great in stocking and suspenders with high-heels. They those really show off your great legs,” I remark, getting aroused by how sexy her legs had become with all that exercise. “You should wear them more often instead of leggings and trainers”.

“It’s a bit difficult to run up mountains or cycle in high-heels,” she replied. “Anyway, they are not for your benefit. No one there is going to see them.”

Susan bent over to adjust her dress and I saw remarkable improvement in her sexy hard defined and toned calves, flexing with incredible definition and muscle tone by wearing those high-heels. I had actually sprang an instant boner!

“PHROAR! Your calves are remarkable. They’re incredibly sexy,” I groaned staring at those big heart shaped muscles, wanting to wank off between them. “ORR I really fancy you dressed like that. Lets stay here and make love. I doubt anyone will miss us.”

I tried to pull her towards the bed but she pushed me off with surprising firmness.

“Pack it in Jimmy, there’s no time for your silliness.”

All throughout the ceremony and reception I couldn’t take my eyes off my wife’s legs, hoping for a glimpse of those big muscular calves, raised up on high-heels and sheathed in sexy sheer black nylon. That dress with nylons and high heels really showed off her amazing figure. She looked stunningly super-fit and healthy. I wasn’t the only one to notice. Quite a few people, especially the guys, remarked upon it, which me feel possessive.

The more I drank, the more I realised how my wife had become a super-fit super-hot GILF right under my nose without me noticing and now that I had, I fancied her like crazy! More than at anytime previously. COR! Susan’s stocking clad legs turn me on so much that when we returned to the hotel room, and she sat down on the end of the bed to remove her shoes, I sat down next to her feel her calves.

“ORR! You have the sexiest legs I’ve ever seen. Especially your beautifully muscled calves. They are so hard and shapely,” I moaned feeling the hardness beneath the silky smooth sheer nylons.

“Jimmy you’re drunk!” she declared trying to brush away my groping hands.

“Please, I just want to feel and worship your calves. They are so sexy and strong. You’re legs are red-hot and I really desire them,” I groan with my hands returning to run over those big balls of muscle.

Susan pushed my hands away again more forcefully.

“If you ruin this dress, you’re in big trouble.”

To my delight Susan began removing the dress.

“You are the sexiest wife in the world. A real GILF and I really want to eff you.”

“I do know what a GILF is and don’t particularly find that a compliment,” she pushed me away again. “I’m certainly not dealing with you when you’re drunk, like this.”

She got down to just her knickers, stockings and suspenders. My jaw dropped and my eyes went wide at the glorious sight. My cock went absolutely rigid in an instant despite the effects of the alcohol I had consumed that evening. It was far stiffer than I’d felt it done for many years.

“Oh Susan, you look sensational! What an incredible body! Oh my God, you’ve got a washboard stomach! Oh that is so sexy!”

She had a ribbed firm belly that would put most teen girls to shame! It wasn’t as deep-cut and ripped like a female bodybuilder but on my wife’s slender body they were more than sensational and had my dick aching! Even her arms and legs looked firm and wrinkle free. Her bust was firm and rounded defying the effects of age and even the top of her chest looked like it had firm pillows of muscle! Then there was well-defined slopes from the back of her neck to her shoulder caps and a clearly delineated collar bone.

“I’ve never seen you look so amazing,” I gasped in rising lust. “Wow when did you get these?” I gasped rubbing my hand over her unexpected grid-work stomach. “They’re so beautiful, incredibly sexy.”

I remembered her mentioning weight training as part of preparing for the Three Peaks challenge, it must be something to do with that.

I was so incredibly horny and don’t think I’d ever wanted her so bad. Pushing Susan down to the bed, I then lifted her right leg up and began to give her calves a good feel.

“Beautiful so beautiful,” I moaned kissing her calves.

“Jimmy stop it now! I mean it!”

I worked my way up, adoring and kissing her firm belly then having to pin her to the bed as she tried to push me away.

“Such a sexy body, so toned and fit. I really want you,” I moaned trying to kiss her passionately while undoing my trousers, which was not easy.

“Stop it Jimmy! I’m ordering you now.”

“I want to make love to my beautiful sexy fit wife.”

I tried to keep her pinned while I got my dick out but was surprised when her arms began pushing mine back with a very determined look on her face.

I was dumbfounded to see thick cords of muscle swell on the top of her slender arms that solidified into hard low hills. Her forearms also took on a strong looking sail shape that resisted my arms with absolute power.

“You have biceps!” I gasped feeling my dick harden even more. “Oh you really turn me on with your sexy fit body.”

I try to kiss her again but the unexpected power of her small solid biceps which were now bulging even larger were holding me off and her sturdy forearms were threatening to break my wrists!

“Jimmy if I say no, I mean no. You’re drunk!”

She was so strong! I couldn’t believe it. The strength in my wife’s arms were actually forcing me to back off. Susan managed to bring her slim long legs, sheathed in sexy sheer black stockings, between us and placed those sexy shapely calves upon the top of my shoulders.

“Since you like my legs so much why don’t you feel what they can do. You bastard!” she snarled with uncharacteristic anger.

The rasping of the nylons as they slid around on either side of my neck filled with the firm weightiness of her long slender shapely legs was highly arousing. Then I sensed her lock her ankles together behind my head and her long slim legs gripped the sides of my neck. That’s when I realised that perhaps this was not the physical experience I wanted. My head was between her upper thighs with my face right in front of her panties. It was no longer a pleasurable place to be as her long slim legs squeezed hard try to make me stop.

“I’m going to make you pay for trying to force yourself upon me, Jimmy.”

Stunned by the brutal crushing power flowing through Susan’s sexy slender long stocking-clad thighs, I couldn’t reply. Trapped in a shockingly strong vice-like grip, my hands were clinging onto the sides of her thighs trying to pull them away from my neck and startled by how firm, solid and unyielding they were. They were more like steel girders covered in nylon than my wife’s sexy legs.

“When I say no, I mean it!” she scolded. “You are not going to rape me, understand Jimmy?”

“OK, please let go!” I gasped feeling stupid for being caught in a head-scissors by my own wife and begging to her!

The hope of prising her thighs apart with my hands vanished when I felt sleek hard slabs of rock hard muscle on the outsides of her thighs, swelling and bulging beneath my hands. I was staggered, I never knew her legs were that muscular!

“Ready to apologise darling?” she asked. “As you’re the one who is in trouble not me,” she sneered.

“Please stop!” I groaned as I struggled to ease the pain crushing down upon the sides of my neck.

“What were you thinking, Jimmy? You are no match for your wife running and certainly no match wrestling her in the bedroom.”

The close-up view of her washboard stomach right before my eyes like a living writhing bumpy table of feminine muscle was erotic and I had to reach out and run my hand over her abs.

“That’s what comes of exercise. How flabby is your belly?” she teased.

Before I could answer, a terrific increase in the power flowing through her legs exerted a crushing pressure on my neck that shocked me. I felt my head begin spin and become light-headed.

“I was toying with you, Jimmy. I can squeeze a lot harder than that. It’s a real turn on for me.”

I gasped as her legs squeezed even harder.

“Your face is turning purple as my thighs restrict the oxygen from your brain.”

The devastating pressure eased off although I was still captive of my wife’s legs.

“I love the strength of my legs. They can generate a lot of power when I need it and crushing you to stop you trying to have your way with me is one of them.”
