“Come on Twi, work it!” Rainbow screamed, glaring down at the girl struggling to lift a hundred pound barbell. “If a girl wants to fuck ME, they need to be tough to impress me.”

Twilight did her best to shoot a glare at her girlfriend, her arms were burning from the exertion. Her entire upper body was drenched in sweat. What made this entire matter worse for Twilight was that it was Rainbow that wanted to date her.

This was their second date. Today they wore matching black skin tight shorts, Rainbow wore what was essentially a blue sports bra that exposed her midriff and showed what little side boob the athlete had while Twilight’s tight purple shirt that fully covered her torso.

Incidentally, it was also the day Rainbow learned about Twilight’s secret, the small bulge in the dark blue haired girls shorts doing well to let the rest of the gym know as well.

“My grandma could lift more than you, Twi!” Rainbow shouted.

“Your grandma is a world champion weightlifter! Applejack and YOU can’t compete with her!” Twilight shouted back, she had to stop, her body needed to rest, beads of perspiration trailing down Twilight's forehead.

“Your point? Prove my granny wrong!” Rainbow retorted, her ire quickly replaced with concern when the barbell sagged, catching it before it fell on her nerdy friend. “Whoa… easy there.”

“I… I can’t take much more,” Twilight wheezed. her body fell lax off the bench. Her face felt like it was a fountain.

“Yeah… why don’t you take a break. Just spot for me then we’ll grab a bite and relax before getting back to it,” Rainbow said, smiling as she helped Twilight off the bench.

“O-Okay, Twilight uttered, fighting off fatigue for the sake of her girlfriend. She took one of their towels and began wiping off her sweat, watching Rainbow walk to a treadmill.

Rainbow turned it on and immediately cranked it's difficulty, casually jogging as the machine attempted to make her run. “See, Twi? Easy.”

Twilight was about to make a rebuttal about the differences between a barbell and a treadmill but her eyes were too focused on the tight, bouncing rear before her. Watching it jiggle ever-so slightly with every step. “Okay…”

Rainbow smirked and turned it up another notch, entering a run. Unaware that Twilight was staring at her ass. The small bulge in Twilight’s shorts growing as time passed.

Rainbow ran for forty minutes, casually letting the machine push her off and stepping off in an impressive way. She smiled to Twilight, who was quickly trying to wipe away drool and fixing her shorts. “Umm… so that… food right?” Twilight asked with a deep blush.

Rainbow felt an unusual amount of pride that she gave her girlfriend a hard on from just running, and got an idea. “Sure… but I wanna get something done first.”

“What? Twilight groaned, her relaxation time going to have to wait.

“Let’s try yoga! it’s more relaxed, more chill, and you're still exercising so it’s fine. Sorry Twi, but you need to do more than flexing your brain and eye muscles,” Rainbow giggled, taking Twilight by the hand to a nearby yoga room.

The room had several woman in there already, an instructor posing while another made sure the girls were doing the correct poses. Twilight watched them with awe, impressed that the human body can move in such ways. The way they moved also excited the Mini-Twi in her shorts.

“Great timing, they’re just finishing up,” Dash grinned, pulling Twilight to the side. The door opened and many gossiping ladies walked out of the room, quickly followed by two rather bulky ladies. The instructors had a very similar body shape as Applejack but more muscled in the arms rather than the legs, they gave the two girls a wink and continued towards the snack bar.

It took seconds for Rainbow to pull Twilight in there. “Alright! Start stretching!”

“You sure about this?” Twilight asked, glancing to the door.

“Stretch, Twi!” Rainbow shouted, scaring the poor girl into doing her pre-workout exercises.

Twilight had some difficulty doing, as some exercises reminded her that she was still hard, no doubt Rainbow noticed as well. What worried Twilight more was she could had swore she saw Rainbow lick her lips.

After exercises were done, Twilight sat down on the mat, awaiting the first position.

“Let’s start with lotus,” Rainbow exclaimed. She sat down and crossed her legs and let out a deep breath. “Like this.”

Twilight chuckled at the rather 'unimpressive' pose and easily replicated Rainbow’s actions. “What’s next?”

“Eager? I like that,” Rainbow cooed, now thinking of all the more 'erotic' yoga positions.

Twilight regretted teasing Rainbow on the lotus position, they quickly descending into more complex positions, each pose getting more ranchier with every move, some of them looked as if Rainbow didn’t have to force her ass in Twilight’s face. But the nerdy girl did her best to keep up.

“Now for the bridge!” Rainbow exclaimed,she laid on her back and raised her rear into the air, balancing on her shoulders and feet.

Twilight let out a sigh of relief, her body became sore again after scorpion pose, the slightly distraction allowing her a slight reprieve as she closed her eyes while raising her crotch.

The feeling of her shorts being pulled off immediately alerted Twilight, her eyes shot open as she looked down to see Rainbow pulling her pants off. They stared at each other for a minute, Twilight's tight shorts around her knees while her dick stood at attention half a foot away from Rainbow’s face. “Rainbow… what are you doing?”

“I like fucking in the yoga room?” Rainbow answered immediately, continuing to pull Twilight’s shorts off while her face remained in the same shocked expression.

“Th-This- Rainbow! This is a public place, we can’t! And on the second date? What the hell?” Twilight shouted, her face beet red.

“Twilight… are you seriously going to try and talk me out of sex when you are as hard as a rock here?” Rainbow asked, emphasizing her point by stroking Twilight’s cock, and making Twilight squeak. “Thought so.”

“What if someone comes in?” Twilight quickly questioned, hoping to save what little dignity she had.

“The instructors know me, the moment they hear I brought a girlfriend to the gym, they let me have the yoga room for a little bit to… have some fun,” Rainbow smiled, tracing her tongue along the crown of her girlfriend’s pecker.

“This happens often?” Twilight gasped, Rainbow’s hot breath gracing her cock’s flesh, making her quiver in need.

“Not really… like three times a girl friend, but you look like a keeper,” Rainbow smirked, she placed a hand underneath Twilight, feeling the egghead’s posture weaken and fall onto her needle like finger, poking into Twilight’s ass. “Keep that pose or I’m gonna fingerbang your ass, Twi.”

Twilight stiffed her resolve, keeping her back straight and her ass high while her first girlfriend made out with her dick. Her desire to moan and squeal were thwarted by Twilight’s resolve and tight lips, doing all she could to withstand the blowjob she was receiving.

Rainbow easily began gobbling up Twilight’s penis, her nose pressing against her girlfriend flesh with every bob. Feeling it harden and throb inside her mouth. She could only chuckle as Twilight struggled to keep her butt up, trying to avoid getting Rainbow’s finger shoved up her ass.

Embarrassingly, Twilight couldn’t contain herself for very long, gasping and moaning as she tried to keep to the bridge pose. She glanced open to see Rainbow nursing her balls while her hand was stroking her dick fast. The combination made Twilight cum all over herself, her skin and purple top splattered with white cum.

Rainbow smirked as she removed her own top, letting Twilight lie down completely and kissing her body, licking up the nerdy girl’s cum as she continued up to Twilight’s lips. “That was pretty hot, Twi,” she cooed, licking Twilight’s cheek.

“Good god… that was… that was…” Twilight uttered, unable to complete her sentence when Rainbow straddled her hips. She felt her hard cock slide across Rainbow’s ass, smearing it’s cum along the crack of her shorts. “R-Rainbow?”

“Wanna know what else is a nice way to get fit? Fucking… lets start with anal,” Rainbow grinned, sliding her shorts off her body and impaling her ass on Twilight’s dick.

Twilight’s hands were clawing at the yoga mat beneath them, gasping as Rainbow took her for a ride. The rainbow haired girl’s hands roughly squeezing Twilight’s perky tits over the shirt. Her ass slammed down hard against her lover’s crotch. Twilight could see the other girl perspire on top of her, pushing her limit while fucking herself on Twilight's rod.

Twilight could feel another orgasm building up, her dick throbbing inside the tight orifice. Rainbow's ass massaging her cock in ways she didn't think it could. She grit her teeth in anticipation when the door opened.

Rainbow casually looked to their newcomer while Twilight became pale. A well muscled girl wearing blue speedos and a light green sports bra walked in. Her blonde slick backed mane and a curious face watching the two carefully, even as Rainbow pumped her hips harder. “Dash.. we have another class in like twenty minutes, could you save this sort of stuff for the showers? Please?”

“Sorry Lightning,” Rainbow chuckled, riding Twilight ever harder. “I’ll clean it all up when we finish. Which means, Twilight will be creaming my ass.”

Colour returned to Twilight’s face as quickly as it left, prompting a chuckle from Lightning. “Whatever makes it easier for me, Cloudchaser was pissed when you had your last girlfriend squirting all over her mats.” She walked over and looked down at Twilight with a curious look. “Girl, you gotta pound up if you wanna get fit. Fuck this bitch!”

Too scared to question Lightning Dust, Twilight gripped Rainbow’s hips and began meeting her descents with oddly strong thrusts, making Rainbow moan. Smiling, Lightning walked off to get her next class ready.

Twilight was easily brought back to the edge, letting out a girly squeal as she came inside Rainbow’s ass, her body twitching and her cock throbbed, firing salvo after salvo of thick cum.

“How was that for a second date?” Rainbow giggled, reaching for her shorts while staying attached her her girlfriend.

“Dehh…” Twilight groaned, sweat dripping off her body, soaking her shirt. Her eyes glazed over as she enjoyed the afterglow of her first time.

Lightning walked over and tweaked Rainbow’s nipples, and dragged a finger along her back, making the rainbow haired girl cum hard on top of Twilight. “Rainbow's weakness is her back. Start rubbing and she’ll do back flips for you,” Lightning chuckled, winking to Twilight as she walked away. “Also… don’t leak cum all over the floor or I’ll have you banned, Rainbow!”

“Y-yeah…” Rainbow moaned, weakly trying to stand up and putting her shorts on. Twilight tried the do the same with her own shorts, taking care for for her cum-slicked dick to not drip onto Lightning’s floors or face the muscular woman’s wrath. Unfortunately, the area around where they were was wet with sweat and cum, forcing the two girls to scrub it out quickly while Lightning watched.

After a quick change and a shower, the two girls left. Both of them using the other to keep standing as they walked back to their dorm rooms.

Twilight was walking to the gym, Rainbow asking her to meet there for another workout. A duffle bag under her arm, Twilight nervously continued her journey.

She immediately saw Rainbow’s multi-coloured mane, but the heavier white and purple haired woman next to her confused her greatly. Easily a foot taller than both herself and Rainbow, the woman wore a brown air force jacket with a black tank top underneath, with blue jeans. The tank top only covering her breasts and showing off the most defined six pack Twilight has ever seen. “Yo, Twi! This is my old friend Gilda, she’s going to join us for our workouts,” Rainbow greeted, pulling Twilight to meet the scary lady.

“H-Hi, I’m Twilight Sparkle,” she stammered in fear.

“Sup, Gilda. Rainbow says you need some help building some muscle, so I’m here to help,” Gilda sneered, one hand around Twilight’s waist and another fondling her crotch, squeezing her dick and balls tightly. “Rainbow says you’re particularly weak in this spot.”

“I was thinking we could start in the yoga room and go from there,” Rainbow explained in a sultry tone. “We got all day after all.”

Twilight began sweating the moment the two girls pulled her towards the gym. This proved to be the best and worst day of Twilight’s life.
