Rare Gains

>Manehatten
>Economic and cultural center of Equestria.
"Big deal." You say getting out of bed to greet the new day.
>A fun summer getaway is what your friends promised you.
>Instead, you peeled yourself off the sweat stained sheets because the entire borough was cutting back on it's electrical usage which meant no refrigerated air in the hotel.
>If you're gonna sweat it may as well be for a good reason, so you grab a pair of shorts and t-shirt, lace up your running shoes and ride the elevator down to the multi-level gym.
>Luckily heat rises, and between the linoleum tiled floor and central location in the building, it wasn't unbearably hot here.
>With most ponies off crowding the pool, you had free reign of the facilities and immediately hit bench press after a quick stretch.
>Between the 45 lb bar and the 45 lb plates on each side, you were going for a light workout today so as not to overwork yourself after a night of melting in your room.
>Rep after rep and 3 sets later, you're taking a healthy swig from your water bottle when the door opens up.
>In walks Rarity, sporting a black leotard with light gray accents and lavender sweat bands around her hooves and head.
>"Oh! Well hello there darling, I wasn't expecting to see you here."
"You think you're surprised? I didn't figure you for a gym rat."
>"Oh please, if I didn't have an outlet for my stress I'd strangle at least one customer a week."
"And the other girls? I figured rainbow would come down for a sweat."
>"That's what I thought but she seems content with laying in the bathtub with all the mini bottles. The fact that they're not complimentary is a lesson I'll let her learn on her own."
>Ha, stupid bird horse.
"Well don't let me keep you, just gonna keep working on my arms for a while."
>"Good luck dear."
>And with that, she heads to a nearby treadmill to start her power walk.
>Not exactly a calorie burner, but it's more exercise than you figured her to be capable of.
>Confident in your form, you add another 25 lbs to each side of the bar and return to your reps.
>With the weight of three ponies in your hands, you keep pumping that iron and maintain your breathing as the clanking sound of the weights echoes through the nearly empty room.
>after building up a good sweat, a purple curl creeps up into your peripheral as you rack the weights to give your guest your undivided attention.
"Yes my little pony, how can I help you?"
>"Don't mind me darling, just taking in... the sights, yes. A little dinner and a show." She says as she unwraps a power bar and takes a delicate bite out of it.
"If that's all you eat and excercise, then it's no wonder you're not showing any gains."
>"Any what now?"
"Y'know, gains." Sitting up on the bench, you remove your shirt and flex your muscles to show her the fruits of your labor.
>"Perhaps muscle bound mares like Applejack and Rainbow are your thing, but I'm quite happy with the state of my body."
>She takes her time to do a little spin for you, and you can't help but notice the way her spandex has crawled up her ass after all that time she spent on the treadmill.
>Lost in the moment, you reach your hand out and slide a finger under the fabric before pulling it out and letting it snap back against her cheek which responds with a satisfying jiggle.
>It's only when she's turned back to face you with crimson cheeks that you realize what you just did, and before you can start explaining yourself, she pushes you back onto the bench with her telekinesis and un-racks the bar before setting it down on your chest.
>"Well Mr. Professional, I suppose you wouldn't mind demonstrating the proper lifting technique so that I too may see those 'gains' that you're so fond of?"
>The evil in her eyes belies the smile on her face as she adds another 25 lb plate to each side before straddling your stomach.
>"Well? I'm waiting."
>She let's go of her magical hold and you catch the weight in your hands before positioning your hands to lift the bar up and off you.
>"And down." She says as she rests her elbows on the bar and leans down to add some of her own weight to the equation.
>You're admittedly quite strong but this is seriously beginning to take it's toll on you after the hot night and with how long you had already been exercising.
>But you keep your chest high and shoulders locked as you bring Rarity down with the bar at an even pace and her azure eyes stay locked on yours throughout the following reps until you count 10 and are thankful when she allows you rack the weights.
>A towel hovers over your head as she wipes the sweat off your brow with her magic and gives you a bite of her power bar.
>"What say you show me one more set? Just to make sure I got the gist of it, hmm?"
"Well-"
>"Of course that was a rhetorical question." she says before switching to reverse cowgirl as she brings the bar back up for you to take hold of.
"Kind of hard to see what I'm doing from there isn't it?"
>"Yes, I suppose it is." And with that she stands up before resting her rounded ass on the bar and balancing herself on it.
>There must be close to 300 lbs being held up solely by your arms, but you know better than to be vocal about that number since offhandedly mentioning her weight could end with you being trapped under a lot more than that.
>Your view of the ceiling is clouded by her tail and honestly your line of sight isn't as vertical enough to be considered looking up.
>Eyes on a different prize, you crank out pump after pump of flesh and iron as she melodically counts each rep as her tail swishes across your face.
>"My, however could I have doubted your strength? Nine."
>This is it, just one more rep before you take her by the hips and show what being a cocktease gets her.
>The bar comes down and you could practically take a bite out of her ass if you so desired, but you hold back and begin the task of pressing her back up until your arms lock straight and you set the bar down before releasing a breath you didn't realize you were holding.
>Rarity slides off the bar and lands on your chest before sliding your torso, all the while her spandex return to their uptight position before she rolls over to face you.
>"So, how about a post workout shake?" she says, grinding her hips in your lap.
"Shake? I wan't the whole damn meal." you retort, throwing your arms around her waist and holding her tight against your body.
>Despite the collective sweat between your bodies, Rarity shows no dissatisfaction and even nuzzles your chest as she draws little circles on it with her hoof.
>"You know what room I'm staying in then." she says lifting herself up off you.
>"After all, I don't appreciate an audience." She gathers her belongings before walking off and flicking her tail at a weight rack where a pair of throbbing cyan wings can be seen poking out from behind it.
>Fucking voyeuristic pegasi.
