Just by looking at the room, one could tell what whoever owned it was serious about working out. Stacks of weights, dumbbells and barbells stood along the walls, with weights ranging from everywhere between five and forty pounds standing in neat piles next to them. A treadmill and a rowing machine stood in the centre of the room, next to a bench press. Each piece of equipment was top of the line, the best an athlete could hope to have. Whoever owned them must have had some serious funds.
And indeed, she did. For the owner of this personal training room was none other than Princess Luna, who was standing in the middle of the room preparing for her morning workout.
Luna may have been the younger of the two royal sisters, but she was by far the larger. Not only height-wise—standing at an imposing seven-foot-two compared to Celestia's six-foot-seven—but in terms of her utterly titanic body, a body capable of pulling a tractor trailer with no more than her pinkie finger. Huge, meaty arms as thick as tree trunks hung from her sides, with mountains of rock-solid muscle crisscrossed with veins and tendons that surged out with the slightest flex of her bicep. Beneath those were thick, sinewy legs—the same legs that could leg-press a load of seven hundred pounds with no complaint. Above her waist was a stunning set of rock-hard, glistening, perfectly-sculpted abs, and above those were a pair of firm, jiggling E-cup tits. Luna was a bountiful mare, and she knew it. She took pride in wearing the most revealing outfits she could, even during royal functions. Indeed, her own workout gear consisted of no more than a pair of tight shorts, stretched around her perfectly-toned glutes, and a dark blue sports bra stretched to its limit around her hefty chest.
Luna grinned to herself as she cracked her knuckles, before flexing her bicep and feeling the muscle beneath with her other hand. She closed her eyes and moaned softly as she squeezed the near-solid mass of muscle beneath. What a rush it gave her, to know that these were the same arms that could tie knots in solid iron rods, and that they belonged to her! She exhaled slowly, a smug grin crossing her face as she opened her eyes.
"Just call me Muscle Moona," she quipped, chuckling. "Alright, let's get to work..."
She stepped across the room to the weights, the floor vibrating slightly under the steps of her size-fifteen feet. She whistled carelessly to herself as she examined the weights and barbells.
"Hmm... four hundred pounds seems like a good starting point." Taking ten forty-pound weights, she set about affixing five each to either side of one of her barbells. Grunting, she picked it up and set it down on the floor with a heavy thud. Rubbing her palms together, she puffed out her cheeks as she got ready to give her massive muscles a thorough workout.
Luna grabbed the metal bar with her meaty hands, tensed her arms, and with a grunt of exertion, hefted it up. Gasping, her muscles bulged, veins appearing against her skin as she lifted the bar up, up and above her head, sweat beading on her forehead. Sweet Faust, she could feel her muscles expanding, growing... becoming more powerful. Making her more powerful. There was no other feeling like it—the rush of exhilaration, of arousal! It was all she could do to not just drop the barbell and start fingering herself there and then.
Moaning slightly, she lowered the barbell to her chest, her puffy nipples straining against the fabric of her sports bra. From there, she began to rhythmically raise and lower the barbell in a series of reps, doing it just slowly enough for her to be able to savour that utterly intoxicating feeling of power. Her eyes were closed as she grinned widely, sweat pouring down her forehead and off her ripped frame as she raised and lowered, raised and lowered... and always, with each raise and each lower, she felt the rush. The rush of endorphins, the thrill of the thought of growing larger and larger.
"Feel the power," she told herself, as she panted from the exertion of lifting the weights. "Feel the burn. Feel the strength...!"
After eighty reps, Luna set the barbell down with a loud clatter. Breathing heavily, she mopped her soaking brow with a towel as she slugged from a bottle of water. She was smiling widely as she wiped a dribble of water running down her chin.
"Eighty reps," she said proudly, marking it in her exercise log. "Not bad, Lulu, not bad."
Again, she felt that flush of arousal, that warmth shooting through her nether regions. Shaking her head, she pushed it out of her mind for the time being. Working out came first.
"Right, what next?" she mused. "I rather feel like sitting down after that..." She smiled. "A few bicep curls wouldn't go amiss, I'm sure."
Thus was how Luna found herself sitting on a padded leather bench, which creaked in protest under her bulk, smiling contentedly while rhythmically lifting a dumbbell in each hand. The little dumbbells were small potatoes compared to her barbells and curlbars, but it still felt good to be doing something with her muscles. Besides, they were still more than Celestia could handle. Luna smirked. Sweet and kind as her elder sister may have been, she hadn't a hope of matching Luna's feats of strength. No, Celestia's strength lay in cramming her fat gut with cakes and doughnuts. It was almost poetic—Celestia's obesity versus Luna's muscles.
Thinking of Celestia made Luna think of the bath they'd shared in the royal bathhouse the previous night. There had been Luna, standing naked in her perfectly sculpted glory, her rippling muscles on full display. And then there had been Celestia, with her huge belly and rolls of fat, frosting on her second chin as she wheezed for air. The contrast could not have been starker. Luna, so fit and spectacular, and Celestia, so fat and out of shape. It had driven home for her just how massive and strong she was.
As Luna remembered that, the flush of arousal hit her again... and this time, it was impossible for her to ignore it. Gasping, she threw the dumbbells down, screwing her eyes shut as she clenched her teeth and squeezed her legs together in an effort to contain her excitement.
With a loud shriiiiip!, her shorts came apart at the seams, her Herculean legs finally vanquishing them and leaving her naked from the waist down, her damp pussy exposed to the air. Biting her lip, Luna reached down and slipped her fingers inside her vag, rubbing and teasing her clit as she moaned, loudly. She was so strong. So powerful... so, so powerful...!
With how flustered she was, it didn't take long for her to drive herself over the edge. She let out a squeak as pussy juices flowed over her fingers, panting as she rode the wave of a wondrous orgasm. Slumping back in her seat, she slowly exhaled.
"I think," she told herself, "that's enough exertion for one morning."
She wasn't sure how she would explain why she was walking half-naked through the castle. She smirked as she got up and gave her naked glutes a slap before heading for the door. But hey... she wasn't afraid to show off.
