1) Shortly after Chapter 1
It was settled. Kate was to begin training in the weight room at the RAF base. Not wanting to let a moment go to waste, the duchess started her new training regiment the next day. William had called ahead and made the arrangements, and a royal chauffeur awaited to deliver the woman to her destination. Typically Kate would drive herself for mundane tasks such as this, but there was now a great deal of pressure for her new hobby to remain under wraps. In the car, she took out her phone and looked up the most efficient free weight routine to build her body up. Almost every routine separated working different body parts across different days of the week, but eager to grow as quickly as possible, Kate decided she would challenge every area of her body at once.
Wanting to comply with the media adviser’s wishes for the time being, Kate wore a baggy jumper and oversized jogging bottoms that covered her muscular form. As she entered the airbase’s gym, almost everyone in the room was shocked to see her. Although she was already relatively well know amongst the base personnel (unsurprisingly given her husband’s position) none of them would have expected to see her in the weight room. Awkwardly, Kate waved, trying to draw attention away from herself before taking out her phone and taking a look at the free weight training program she had loaded onto it earlier that day.
Eager to get started, Kate strode over to the dumbbells. She started reaching out for a pair of 10 kg dumbbells “Whoa there miss, I don’t think you realize how heavy that is.” One of the men nearby interjected, noting the weight she was going for.
Kate turned and quickly shot the man a scolding glare. He was a large and particularly well muscled specimen, probably one of the ground crew. With a huff Kate turned away from the man and grabbed the dumbbells. What he couldn’t see was the firm, powerful biceps that popped up beneath her jacket as she did so. The duchess proceeded to curl the weight just as she had seen on the video she watched earlier. To her surprise, the weight wasn’t nearly as heavy as she imagined it would be. Without much fuss, she managed to curl the iron, feeling a slight burn in her arms from the motion.
“Blimey, you’re bloody strong!” The man admitted, scratching his head at the display. “For a girl that is.” he added, somewhat condescendingly.
“This?” Kate asked nonchalantly. “This is pretty easy if you ask me.” she explained with a smirk before finishing up her tenth repetition. She let out a dissatisfied sigh before putting the weights down.
“What’s wrong? Aren’t you going for lots of reps to tone up?” The man asked.
Kate cocked an eyebrow. “I’m here to build my muscles and strength up!”
After resting another moment, Kate was ready to upgrade to the 15 kilogram weights. As she picked them up, she could immediately feel they were significantly more difficult to lift than the pair she had just used.
“Hey!” the man started.
“Just watch.” Kate interjected, and before he could say another word, she proceeded to curl the weight. The difficulty of the task forced Kate to lift the weight slowly and deliberately, but she still managed to do so with perfect form. The man’s jaw dropped slightly as he witnessed Kate’s minor display of strength. After six repetitions with each arm, Kate felt that she was adequately taxed by the motion and put the dumbbells down before resting.
“Good show, but if you keep that up you might get all… bulky” the man explained.
Kate let out an aggravated sigh. “And what exactly is wrong with that?”
“It’s just kind of…” The man started. “You know?”
Intrigued, the duchess raised an eyebrow. “Gross?”
“Yeah.” the man nodded, glad that she seemed to understand what he was going for.
Kate let out a huff before getting up and grabbing onto the dumbbells again to complete another set. Since her muscles were already challenged, she found the motion was even more difficult, but she managed to finish up a solid set of five repetitions.
“Oy, didn’t you hear what I said?”
Kate smirked. “Tell you what big guy, over the next couple months, I’ll prove to you that ‘bulky’ muscles on a girl aren’t a bad thing at all.”
“You’re just gonna hurt yourself if you keep this up.”
Kate shot him another scolding glare. “Just leave me alone for now, alright?”
“Besides, women can’t really get very strong with drugs, ya know?”
The duchess simply glared at him.
The man shrugged before taking off to another section of the gym. Kate continued following the workouts on her phone to a T. She was both delighted and surprised to find that she was already stronger than the typical recommended starting weights for women to use. While it was recommended to use a spotter for some of the heavier and more involved lifts, Kate opted to handle things herself, not wanting to draw any unnecessary attention to herself.
Something toward the gym’s exit caught Kate’s eye. She glanced over and noticed that there was a pair of men in suits approaching everyone who exited. Curious, she strategically performed her next workout with some weights closer to the door so she could overhear what they were saying. To the duchess’s surprise, the men were apparently debriefing anyone who saw Kate in the gym, forcing them to secrecy about her activities there.
It surprised and bothered the duchess that there was such an elaborate effort being made to essentially censor the fact that Kate was getting fit. Seeing this blatant attempt to cover up something that she felt was positive angered Kate a bit, fueling her rebellious streak further. She was even more determined than ever to become so muscular and strong that it couldn’t possibly be hidden!
2)
The following day brought Kate’s former adversary back to the forefront: soreness. She had stopped feeling sore after mastering the machines in the house, and wasn’t expecting to have every muscle in her frame ache once again.
As much as it pained her to do so, Kate decided to forgo her training for the day to allow herself to properly rest up. She found that her appetite was even higher than it was a day ago, and gleefully engorged herself, eager to provide her body with everything it needed to grow even further.
–
The next morning, Kate was glad to find that her soreness had all but vanished. She felt particularly brimming with energy, and was quick to get to the base in order to start another workout. Once again she had to be driven to the base, and once more she wore baggy clothing.
At the base’s gym, Kate started using the weights she had last time, only to find they were slightly lighter than before. This delighted the duchess, leading her to eagerly increase the resistance of nearly every lift she performed. Experiencing this almost immediate progress pushed Kate even further, increasing her motivation to new heights.
Over the next week, Kate continued this pattern. She’d push her body to its limit one day, recover the next, then go all out once more the day after. Just as she hoped, every day she entered the gym, all of her lifts went up slightly higher compared to last time. She also found she was becoming less sore on each day after she worked out. By the second week, Kate found that the soreness had become essentially trivial, and she proceeded to exercise every day – completely forsaking rest days altogether.

Two weeks after Kate started working out at the RAF Base
–
Kate began to notice that most of her clothing barely fit her anymore. Everything was incredibly tight. To start with, it was an effort to simply get her jumpers over her burgeoning back, shoulders and… chest? To her surprise, her breasts seemed to have grown slightly. Even after forcing a top on, if it had sleeves, her arms would invariably push the fabric to its limit, and a couple inches of her midriff were exposed, revealing the bottom of a surprisingly thick 8-pack. She faced similar difficulty putting on bottoms as well, as not only had her legs grown considerably in size, but her glutes had as well.
“Guess I’m stuck wearing baggy stuff until I get some shopping done.” Kate realized, finding it somewhat ironic that she was forced into following the media adviser’s plans.
At the gym, Kate spotted the man who had given her a bit of trouble on her first day there. She noticed he was hard at work at bicep curls – fitting since that was the same exercise she was performing the day he bothered her. The duchess slowly approached, noting that he was hoisting 20kg dumbbells with quite a lot of effort. In fact, the man was clearly sacrificing proper form just to simply get the weights up.
Silently, Kate strode up next to him and grabbed a pair of dumbbells of the same weight. Nearly effortlessly, she began curling the weights – creating a stark contrast between the two. As the man grunted and struggled to finish his set, Kate coolly and easily sailed through hers.
Noticing what was happening, the man stared, slack jawed. “Is this… some kind of trick?” he stammered, unable to comprehend what he was seeing.
“Not that I know of.” Kate said before putting down her dumbbells and grabbing the pair that the man had just used. She began curling them just as easily as she had with her own. “See?”
“No way.” he said blankly.
Kate winked before putting the weights down and picking up a pair of 22.5 kilogram dumbbells and began curling those.
“You’re…”
“Cat got your tongue?” Kate teased as she continued her workout.
“You’re stronger than I am!”
“It appears that way.” she agreed.
“Bloody hell!” he took a moment to collect himself. “Cripes, guess I owe you an apology for doubting that you could do it.”
“I’m glad you understand, though there was something else you were rather rude about…”
The man recalled their prior encounter before realizing what she was referring to. “Well I’m afraid I can’t really tell since you’re wearing all of… that.”
Kate began thinking over what she should do. She could very easily take the jacket off and reveal her upper body in all of its glory, though that might cause quite a stir with the media advisers. On the other hand however, everyone in the gym had been commanded by now to not utter a word of her working out there, so it’s not like anybody would know.
“Ah, stuff it.” she muttered before promptly stripping her jumper off. All that covered her upper body was an incredibly stretched sports bra. “Well?” she asked before placing her hands on her hips.
The man’s jaw dropped. “You’re… you’re…”
“I’m what?” Kate asked, raising an eyebrow.
The man blushed slightly. “If you don’t mind my saying, you’re bloody beautiful!”
“I told you that natural muscles on a girl look great!” Kate said before flexing up her impressive 15 inch arms.
Kate’s display began attracting the attention of the other gym-goers, and soon everyone in the room began flocking over towards her. She began showing off her strength, performing some impressive lifts that only the strongest of men there could top. Before the day was through, a couple of women who were primarily using the gym for cardio approached her, asking for her advice on a routine.
As Kate left the gym for the day, she was especially pleased with what had transpired. Not only had the man from earlier become more humble, but she finally began leading other women towards the path of strengthening their own bodies. The day’s success motivated Kate even further, leading her to want to push herself harder so she could inspire more people.
3) Three weeks since Kate began working out at the RAF Base
Kate was lounging in the Langlsey home’s living room. She had already completed her workout for the day, and was enjoying a ‘light snack’, which in reality would be a large meal for anyone else. She took a gander at the latest copy of The Sun and noticed that once again she was plastered all over its cover.
This time, instead of being scantily clad in a bikini, there was an image of her wearing her incredibly baggy attire. “IS KATE PREGNANT?” the cover inquired, prompting the reader to look within for answers. With a sigh, Kate read the article, which speculated that she must be hiding her ‘pregnancy weight’ with baggy clothing. She chuckled. While the rag was correct that she had grown larger, they were far off in regards to what the clothing was hiding.
The front door opened and William came in, having just home returned from his latest mission as a search and rescue pilot. The duchess got up to greet her husband and as she approached him she realized something – she was barely shorter than he was now. William must have also noticed this development “Looks like your muscles aren’t the only thing that’s growing.” he noted
The burgeoning woman gave William a playful wink. “I like the new perspective.” she noted.
William looked his wife up and down before nodding. “It makes those lovely legs of yours even longer.” He reached over and grabbed a hold of his wife to embrace her before realizing just how muscular her arms had become. He gave them a squeeze and was visibly shocked at how much they had grown in a mere month.
“They’re damn strong too.” Kate said, sensing what her husband was pondering. With a fit of spontaneity, the duchess grabbed hold of her husband and with one swift motion lifted him straight up off the floor before carrying him ‘bridal’ style. “Let’s go have some fun with this new body of mine.” she said with a laugh before bringing both of them to the master bedroom.
–
After the royal couple’s fun, Kate was in the mood for a back massage. William was happy to oblige, eagerly taking the opportunity to spend more hands on time with Kate’s muscular form.
As the prince dug his hands into his wife’s back, he immediately noticed how much firmer the muscles beneath his fingers were compared to the last time he had massaged them. He couldn’t believe how amazing the combination of soft skin covering mounds of powerful flesh felt to touch.
While she enjoyed her husband’s efforts, something seemed off to Kate. “Love, I appreciate your efforts so far, but do you think you could maybe dig a little harder?”
William gulped lightly. His wife’s back had become so firm and powerful that his usual level of pressure while massaging her wasn’t satisfying! He tightened his grip and dug his fingers deeper.
“Mmm, that’s the ticket.” Kate cooed. “You’re the best.” she smiled.
“I am to please.” William continued kneading the powerful muscles in Kate’s back. After a minute or two, he realized that his hands were starting to hurt a little from the consistent force he had to apply. “Err, dear, do you think you could maybe stop, you know, showing off?”
“Huh?” Kate wasn’t sure what William was referring to.
“Your back love. You’ve got it all tensed up to show off your muscles.”
Kate let out a soft giggle. “Oh, you mean like this?” she asked before actually flexing her back, causing the muscles to harden and buldge even further.
William found that after his wife had hardended her back even further that massaging it was an almost impossible task. His fingers barely dented the flesh beneath them. “Ooof.” he gasped. “Fine, fine, you’ve proven your point.”
Kate giggled again before untensing her back. William powered through the rest of the session, determined to prove that he could still comfort his wife. “You know love, maybe you’ll end up getting some beefier forearms from all of this.” she mused.
“Guess you’d like that, huh?”
Kate chuckled. “I love you just the way you are, but I suppose having some more power to your grip would be nice.”
This continued for a few minutes longer until William decided he needed to discuss something with her. “So dear… Sorry to drop this on you, but in a few days I’ve got to leave for a couple weeks on family business.”
Kate let out a sigh. She had grown tired of the typical royal business.
William continued. “You can come as always, but it’d be difficult to keep up your new workouts.”
The duchess’s eyes lit up. “Are you saying I can skip this time around?”
The prince chuckled. “I’ll cover for you. What do you say that we meet up at a French chateau for a little getaway when I’m done?”
“Mmm… sounds good.” Kate cooed.
–
The rest of the day continued uneventfully. William left a few days later as planned, granting Kate the house to herself to fully focus on growing as strong as possible. While her motivation was already extremely strong, she was pushed even further to impress her husband when they would meet again in two weeks.
Kate began eating even more than before, practically forcing herself to finish the numerous large meals she prepared throughout the day. Before long, she found that each and every day she was stronger than the last. A week into her time away from William, she came to the conclusion that she had more than enough energy to workout even more – so she began lifting weights in both the morning and evening.
To Kate’s delight, she was becoming slightly stronger between the workouts themselves, leading her to gain strength at an even faster rate than before. Before she left for France Kate had broken all the lifting records at the base gym, each time surrounded by a cheering group of service personnel. The man who’d had a go at her on her first visit congratulated Kate each time, he had tuned onto one of her biggest fans.
4)
The French Chateau
After William landed in France, he was greeted to a message alerting him that Kate was already at the vacation home waiting for him. As he sat in the back of his royal transportation, all he could think about was how much Kate may have transformed from the last time he saw her. He knew that it was unlikely she could grow much stronger, but he still entertained the thought in his mind.
He started texting during the ride, but she remained cryptic and playful. The final message he received was “I’ll be on the back patio waiting for you. Come alone.” After what felt like a short eternity, William finally arrived. Without hesitation, he dismissed his staff, threw his luggage in the living room and bolted for the back patio.
The sight that awaited the prince was mindblowing to say the least: Kate was lounging in the French sun in a micro-bikini that barely covered her at all. All of her muscles had visible gained a few inches since the last time they met, giving her a physique comparable to that of a professional male bodybuilder. Despite her immense musculature, Kate retained her feminine form – in fact, her breasts seemed larger than ever.
Noticing her husband had arrived, Kate stood up, allowing William to fully take in her improved form. She had an imposing V-shape to her form as an impossibly wide set of shoulders cascaded downward to her slim waistline. As he approached his muscular wife, he not only realized how much wider she was, but noticed that she stood only a smidgen shorter than him.
With a confident smirk, Kate circled around her husband until she was between him and the door. She proceeded to lightly and playfully give him a shove, causing him to fall back on the lounge chair she was just sitting in. “Sit back and enjoy.” she said before breaking into a classic double bicep pose, causing her 18 inch arms to pop up in all of their glory.
William watched, slack jawed as he made every effort to not drool on himself. Kate continued with a few more simple poses, reveling in how enchanted her husband was. “I take it you’re enjoying the show love?” she asked.
William smirked. “You have no idea, this is like a dream come true for me!”
Kate switched into a ‘most muscular’ pose, showcasing her thick, striated pectorals. “Do you think I’ve maybe taken things too far?” she wondered out loud.
The prince quickly shook his head. “No way!”
The duchess turned around, exposing her nearly naked backside to him before starting a full lat spread, causing the thick ridges of her back to fully flare out. Everything about that moment seemed perfect for the royal couple. William got to fully enjoy his wife’s improved body, and Kate loved the attention and admiration he provided.
Not everything was perfect however… Little did the couple know, from the distance a cameraman from The Sun was giddily snapping pictures of the muscular display!
To be concluded in Chapter 3!
