Mari's eyes gleamed with anticipation. "Recently, my mom just keeps talking and talking about how awesome it is at her gym. Focused Fitness, remember? Anyway, she's really wearing me down by singing its praises, and now I kinda wanna check it out."
"And you want me to tag along?" You asked.
Mari nodded. "Totally, dude. They've got a tiny-only section of exercise equipment, and even a few tiny fitness training programs. Plus some mixed classes and workout areas. It's a pretty inclusive place." Mari winced. "I know you can't say that about a lot of the places here in Oakland, but Focused Fitness is legit."
You sighed and rolled your shoulders. "Well, I wasn't really planning on working out today, but why not? Sounds fun, especially if it's with you, Mari."
Mari grinned wryly. "And why's that, pipsqueak? Because it feels good to exercise, or because you're going to be ogling your gorgeous giantess girlfriend the whole time?"
"Now, that's a loaded question." You replied with a laugh. Mari laughed to, lightly jabbing you with her toe as recompense.
While you picked yourself up, Mari took the opportunity to change into something a little more fitting for an extended workout session. She jogged upstairs to her bedroom, leaving you to twiddle your thumbs and wait for her return. You passed the time by thinking back to your past experiences at Focused Fitness.
You'd never been there in any official capacity, but in total you'd been there about twelve or so times by complete accident. Three times you'd been taken there because Mari had accidentally dropped you into Rio's gym bag. Twice you'd been dragged there by Jenna and Ashley (both times a sticker on Ashley's gargantuan glutes, courtesy of Jenna). Four times you'd gone with your mother (once wedged deep in her cleavage, once in between her meaty ass cheeks, once in her shoe, and once mistaken for her sweat rag). The last three times were random women who had crushed you to their butts or feet and headed to the gym unaware. Thankfully, you'd been able to hitch a ride to safety with Rio each time.
Mari returned, and she was a goddess in her form-fitting red sports bra and sleek compression shorts. You didn't bother to hide your appreciative stare, which earned you an eyeroll from Mari once she noticed. Your girlfriend then picked you up gently, grabbed a random gym bag from the closet, and headed out to her car with you. Once in the car, she deposited you in the cupholder and drove off to the gym, practically bouncing with excitement at the idea of taking one of her mom's classes.
The ride was short, and Mari picked you up again once reaching the gym. She pushed open the doors and headed inside, and uncurled her palm to allow you to gaze out and take in the sights for yourself.
Focused Fitness was a sprawling complex of a gym, and you couldn't even see it all from the entrance. There were rows and rows of treadmills and bikes, not to mention ellipticals, stair-climbers, and every other machine under the sun. A distant corner of the gym was filled with more weights and strength training equipment than you thought possible, and another corner had exercise balls, ropes, and other gear. A few signs hanging on the walls mentioned that locker rooms, showers, and private classrooms were further down the hall.
You strained your eyes a little more, and you could make out the tiny-only section that Mari had mentioned earlier. Disconcertingly, it was placed near the back wall, sandwiched right between the weightlifting area and the aerobic gear area. It was about four feet by four feet, and seemed to have all the basic gym equipment, but at suitable tiny size. It was only delineated by a bright red line of tape surrounding the zone, and even that tape seemed to be peeling at the edges. Multiple women passed frighteningly close to the section, and seemed oblivious that they had done so.
On the topic of women, there were so, so many of them in just this opening area of Focused Fitness. You counted at least thirty women, and it was still early. As you and Mari stood there gawking, at least another five entered behind you. Every woman was jaw-droppingly gorgeous, and it took all of your mental fortitude not to stare at the curvaceous and fit women in their tight workout clothes. You were beginning to think this was not the most amazing idea anymore.
"Lost, hun?" A soothing voice said, snapping you from your thoughts. You and Mari turned to face the voice, and you suddenly found your vision of the gym and its residents replaced by a monumental pair of breasts that strained the fibers of the too-small sports bra containing them. The perky, gigantic chest was all you could see even as you strained back, and you gaped with awe.
Mari, however, was at eye-level with the owner of the tremendous tits, and she smiled sheepishly at the woman. "Sorry, it's my first time here. My name is Mari, I'm Rio Fuertes' daughter."
The woman grinned. "Oh my god, really? Ahhhhh! You're such a cutie!" She pumped her fist. "My name is Ellie, and I'm the tiny-certified instructor here at Focused Fitness. Nice to meetcha!"
Mari smiled back. "Likewise. Oh, and here's my boyfriend." She said, lifting you up in her palm, rising you up past Ellie's huge chest to her radiantly smiling face. You waved at the well-developed fitness instructor, but before you could properly introduce yourself, Ellie let out a squeal.
"Ahhh, what? You're even more adorable, little guy!" Ellie giggled, and somehow looked even happier. "Oh my god, you have GOT to come to my tiny-only class, cutie! It starts in just a few minutes!" Ellie played with a lock of her brunette hair. "Don't know how many guys I'll have today...I keep losing class members. I don't know why they don't stick around..." Ellie mused, before flashing a confident grin. "I mean, sure, I don't hold back on the little cuties, but that's because fitness is important! You can't slack off, and little adorable squishies get no mercy from me!"
Mari laughed, overcome by the woman's exuberance. "On that note, actually, I'm here to join my mother's class."
A stern but warm voice spoke from behind Mari. "Is that so?"
Mari turned to find Rio standing there, water bottle and yoga mat in hand. "Oh, mom! What's up?"
Rio chuckled. "Really, Marisol? 'What's up'? This little surprise visit is unexpected. How long were you planning on stopping by and joining my class?"
Mari smiled sheepishly. "Since this morning. Kinda a spur of the moment thing." She moved you closer to Rio. "Hot stuff and I are gonna join your class, if that's okay."
Rio folded her arms in front of her abundant, firm chest. "I'm the last one to disparage a good workout, Mari, but I wish you'd told me sooner. I appreciate this, I really do, but my class isn't mixed. It's full-sized women only. Sorry."
Mari frowned. "Oh, what? Really?" She flicked her gaze down to you and winced. "And there's no exceptions?"
Rio quirked her lips to the side. "Not...usually. Especially not when we have tiny-only classes..." Rio jerked her head towards Ellie, who enthusiastically waved and locked eyes with you, winking. "...or our very own section for tinies to exercise out here on the floor." Rio reminded you, pointing to the far corner of the gym.
Mari sucked in a breath. "I really wanted to workout with Matt, mom."
"I understand that, Mari, dear." Rio sighed. "Unfortunately, rules are rules. I might be one of the longest-employed instructors here, but I'm not above Focused Fitness' policies. I can't get in trouble just for you and Matt to have a very physical date."
You and Mari both blushed profusely, and Ellie laughed joyfully at the teasing. After a moment, Rio checked the clock on the wall.
"Class starts in a minute, Mari. You can still come by yourself." She said.
"I know, mom." Mari admitted glumly, before gently setting you down on the nearest table. She stared down at you sadly. "I'm really sorry about this, Matt."
You were disappointed too, but you hid it with a smile. "No problem, babe. I'll be fine. Go have some fun, I'll make do out here."
After a moment, Mari nodded, appreciative of your consideration, and walked off down the hall at the back with her mom. Only Elli lingered, who gazed at you with overwhelming friendliness and grinned.
"You could still join my class, cutie!" The bodacious brunette stated, leaving the offer open as she turned on her heel and wandered off towards a separate room down the hall, rounded butt cheeks bouncing along in her skintight spandex shorts.
You put your hands on your hips and surveyed the landscape of Focused Fitness. Left to your own devices, what do you decide to do?
1) You head over to the tiny-only exercise section out on the main floor. There, you meet with a few other likeminded tinies, and start getting a good sweat in. However, it isn't long before an incident (whether accidentally or not) occurs that threatens the residents of the tiny-only section.
2) Though somewhat apprehensive, you decide to join Ellie's class, so you head across the gym to the room she went into. Ellie is overjoyed to see you join her class, but your anxiety only grows as no one else shows up, leaving you as the only student. Not one to waste an opportunity, Ellie enthusiastically decides to give you an intense and unforgettable one-on-one personal training session.
3) Desiring to workout with your girlfriend, as had been the initial plan, you make a beeline to Rio's classroom, ignoring the rules about it being women-only. Once making it there, you sneak inside and try to make it to Mari without being spotted, crushed, or worse. You know full-well Rio's patience runs thin when people make dumb decisions...like this.
