Where do they go?
Gym 1 (Alkim)
Alkim
Holy fucking shit!
Alkim couldn’t believe his eyes. He’d seen more than enough of her tits before to notice that they'd changed.
How are her tits so huge today? I’ve never seen this much tit before!
Luckily, he was too busy staring at Kate’s chest to physically drop his jaw and openly gawk at the sight.
Alkim felt like he had to say something. There was no way he could just let this pass by without comment.
“Uggghhh, Kate…” Fuck, what can I say tactfully? “Um… I don’t think that top fits.” Understatement of the year, every exposed inch of titflesh was clearly bulging out past the fabric. Her cleavage alone outsized a normal woman’s chest.
Kate groaned, “Yeah dude, I fucking noticed. It’s like everything I ate this week went straight to my tits, none of my shit fits anymore! That’s why I need to go to the fucking gym!” Her voice had hit an anxious, almost panicky tone.
Shit.
Kate was definitely not having fun with this. Alkim knew how worried she was about getting fat. Kate spent a lot of time managing her appearance, maintaining a constant figure, which he more than appreciated. This was a real grenade in her weekly regimen.
More like two grenades.
“Shit, I’m sorry dude,” he lied. Alkim was definitely not sorry, he thought this was the most incredible development. If he’d known Kate was just a few days of overeating away from growing those tits, he would have been cooking way more calorically dense meals from day one. “I didn’t mean to stare, just... I didn’t know tits could balloon out like that in a week!” At least that wasn’t a lie.
“Same dude!” yelled Kate, “I didn’t think this was possible either!”
“What’s not possible?” Said a voice from down the hall.
Oh shit, too loud.
All the commotion brought their other housemate, Mikaella, out to investigate. Apparently neither Alkim nor Kate knew she was home until that moment. She'd left on Friday for work, and none of them ever bothered to ask her when she’d get home since she rarely knew beforehand anyway.
Mikaella turned the corner into the living room and nearly walked headfirst into Kate’s expanded bazooms.
“Holy shit! Kate!” yelled Mikaella. Apparently Alkim wasn’t the only one totally gobsmacked by this development.
Mikaella was a short Filipina girl. Nineteen years old, and, Alkim assumed, somewhere around five-foot two-inches in height, with black hair, and somewhat dark skin. Alkim didn’t really think of her as hot, but she was definitely cute, just not very curvy. Like Vicky, Mikaella had also met Kate when they were working at the Karaoke bar, but she had quit that a while ago. It was no real secret that Mikaella was a sugarbaby, but she never talked about it, probably out of embarrassment or shame, and the rest of the house never brought it up.
Still, Alkim liked her; she was the closest housemate to him in age, and she was always nice to him. Mikaella never had any issue with him staying there, especially since he’d driven her around a few times, and helped spruce up her community college app, no questions asked. Overall, he thought Mikaella was a nice person, but she was fresh out of both high school and foster care. Neither experience had left her the most emotionally mature or tactful person in the world, though understandably so. For good or ill, Mikaella never hesitated to speak her mind, or, in this case, yell her mind.
Mikaella launched a litany of questions and observations at Kate, “When did your tits get this big?! I thought you were just an F-cup! What fucking size are those?!”
Well, that’s one way to ask a girl about her figure...
Mikaella’s eyes were locked onto Kate's tits, now practically at the shorter girl’s eye level thanks to the overtaxed sports bra.
“Jesus, fuck dude! ” Kate exclaimed, clearly not ready for all this attention. Kate tried to cover her tits up with her arms, but that was never going to work. The move only pushed her tits down and to the sides, causing the excess tit-flesh to spill into her armpits. “I just gained some weight this weekend, okay! Back off!” She yelled and stamped her foot for emphasis, but the motion had the unintended effect of making her incredible milkers wobble in front of her housemates.
Unsurprisingly, this did nothing to dissuade Mikaella’s curiosity. “Dude! No way! Tits don’t just grow like that! What are you taking? Did you start birth control? Wait, why would you need birth control? You’re a lesbian!”
Kate must have had enough of this. “Leave me alone!” she yelled at the nosy girl, grabbing Alkim’s arm, and his water bottle. Refusing to answer any of Mikaella’s questions, Kate pulled him through the front door and slammed it shut, cutting off the line of questioning. She sighed in deep frustration and started drinking from Alkim’s water bottle.
Wait, why did she grab mine?
Alkim thought that was weird, but he wasn’t going to risk upsetting her further. Everything in the last couple of minutes was weird, she probably just panicked under all the questions about her tits. Tits that Alkim had an unobstructed view of, as she did her best to chug the contents of his water bottle.
She was gulping his water the way one chugs hard liquor from the bottle after a terrible argument. Alkim had to say something, but he didn’t want to set Kate off again. “You okay, Kate?”
After a moment Kate finally stopped drinking his water. “Yeah, I’m fine,” she said, a lot more calmly than he expected after all that. “Let's just go. I need to burn off this fat, and I’m gonna need you to help me do it. Kuài! Kuài!” Quickly! Quickly! She often defaulted to Chinese with him when she was stressed.
Kate handed the bottle back to Alkim. He took a swig himself, but just before he could cap it Kate took it back, drank again, and then returned it to him.
Wonder what’s gotten her so thirsty…
The two arrived at the 24-Hour-Fitness in a few minutes, and Alkim could tell this was not gonna be a normal day at the gym. Usually the two went their separate ways at the entrance. They just had very different fitness goals. Kate hated jogging, while Alkim loved cardio. Alkim was also a lot stronger than Kate, so they couldn’t use the same weights, and there was no way she could spot him safely.
Today was different; Kate’s whole goal was cardio and weight loss, so they started off with some stretches. Alkim proactively avoided being a creep by staying to her left while they did hamstring stretches; legs straight, bending over to touch the ground. His natural flexibility was pretty terrible, but years of jogging and martial arts meant he could almost get his full palm flat on the mat and see between his own legs.
Oh, goddamnit!
Alkim hadn’t accounted for the mirrors right behind them that gave him a full view of Kate and her tits. Gravity was pulling them down to her chin. And as if that wasn’t enough, Kate had her hands around her ankles, and was pulling her torso closer to her legs. This had the effect of squishing her tits into her thighs.
Fuck me! What a vision.
This was even hotter than that time she’d worn that obscene bathing suit during a night-swimming session. He had to stop looking. The gym was the absolute worst place to get a boner, especially in these shorts. And they were only on the first stretch. He would try to keep it together, keep it nonsexual, but she wasn’t going to make it easy for him.
Alkim knew Kate wasn’t trying, but in that undersized sports bra basically any stretch or motion made her overgrown tits look irresistibly huge, hypnotic, even.
Butterfly stretch? Tits squished between her arms. Cobra stretch? Tits dangling out in front. Calf stretch? Admittedly that didn’t accentuate them, but the tits were still there, jiggling, existing, making him want to chug an entire milk carton. Alkim bet she could charge serious money for this view. He’d seen camgirls way less attractive than Kate doing way less sexually charged exercises raking it in.
No! Stop thinking about porn of Kate!
Alkim was already sweating bullets, and they hadn’t even started on cardio yet. He gave himself a short reprieve from Kate (and her tits) to refill his water bottle, which she immediately snatched upon his return. He made a note on his phone to get Kate her own metal water bottle later.
Next was cardio. Kate took the treadmill all the way in the corner, Alkim took the one next to her. He usually did his own jogging outside, since he got bored too quickly running on the treadmill. He needed to be going somewhere, or have something interesting to look at when he ran, which is why he preferred trail runs with natural vistas, like trees, the sea, or mountains.
This time, Alkim had more than enough natural mountains to watch from the comfort of his treadmill. Each of Kate’s stride sent her massive boobs bouncing almost up to her face where they crashed into each other before succumbing to gravity and falling back into the overtaxed sports bra, stretching it down almost to her navel. Alkim thought it was a most wonderful sight, completely mesmerizing. Yet, even his horned up brain knew all that bouncing had to be painful.
“Ow! Fuck!” yelped Kate. Alkim’s perverted instincts were correct. After just fifteen seconds of jogging Kate had to stop the machine. She raised her free hands to support her sore tits. Her palms sunk deeply into her own flesh, pushing some extra cleavage up towards her neck. “Ow, ow ow! That’s it, no more jogging.” she hissed.
Alkim didn’t really know what to say, and he almost forgot he was still jogging. The blood pumping into his legs was probably the only reason he didn’t also have a boner right then. Alkim powered down his machine and followed after her.
He had only just started to work up a sweat, and as nice as it was watching her body, he didn’t want to get a boner in front of her, and he still needed to get a real workout in.
“Ummm, I should probably get a few sprints in here, then I’ll hit the weights. Maybe you could use the stationary bike, and meet me at the dumbbells?” Alkim suggested with as much tact as he could muster.
Kate just sighed and made her way over to the bikes. He did a couple of high speed sprints on the treadmills and went to the dumbbells, far, far away from Kate.
Alkim’s workout continued, and, after twenty-five minutes of cycling, Kate must have worn herself down, because she was suddenly hovering over Alkim at the bench press, with two dumbbells in her hands, and her amazing boobs dangling over his head. Alkim briefly imagined her trying to spot him as he laid there, smothering him with her tits in the process. He had to quickly banish the thought to keep his form from slipping.
He put down his heavy dumbbells and sat up, taking in her post-cardio appearance. A thin shine of sweat coated Kate’s entire body, and her clothes had some dark patches, but she was still extremely photogenic. Fuck, how does she still manage to look like a fucking shiny goddess after all that cardio? Alkim hadn’t even pushed himself all that hard, and yet he was sweating bullets.
“How was the cycling?” he asked.
“Meh.” Kate mumbled. “Better than jogging, but I still hate cardio. This is just not my day. Can I use the bench after you? All the others are taken.” Kate asked while gesturing at the grunting dudes that occupied the rest of the weight room.
“Sure, I’m basically done anyway. I can spot you.”
“Thanks.”
She sounds kind of down. I should probably do something for her when we get back, maybe order her that water bottle.
Alkim dropped his dumbbells and peeled his sweaty back off the bench. He couldn’t help but notice there was a lot of sweat left behind. The shine outlined his entire body, with an extra damp patch where his head was a minute ago.
Kinda gross, she’ll expect me to clear that off.
He grabbed a wipe after he re-racked the dumbbells. To his surprise, Kate must not have noticed. She just sat down with her own twenty-pound weights on her thighs, and laid back into Alkim’s excessively sweaty outline.
Alkim expected Kate to be disgusted and drop the weights, but to his surprise she didn’t say anything at all. Kate just laid there for a second and started doing reps with a perfectly formed and focused face.
It was just so bizarre for her. Kate was normally very easily grossed out. Alkim was so surprised that he barely even had time to be a pervert. He barely noticed how her tits had flattened out against her chest and partially spilled into her armpits, or how her arms and pectoral muscles jostled them as she brought the dumbbells up, down, up, down, up, and down…
Focus!
Alkim **** his eyes to lock onto her form, not her jiggling milkers. He knew it was not a good idea to get distracted when spotting someone (even though Kate wasn’t using a bar), but damn was she making it difficult for him.
He settled for keeping his eyes moving between her form and the jiggling motions of her tits, safe in the knowledge that she couldn’t see his face from this angle.
Good thing too, because he noticed her elbows bowed in slightly. “Focus! Keep your arms straight, perpendicular to the ground,” he corrected.
She fixed her form immediately, and continued her set.
Huh, expected her to at least grunt out a “shut up.”
“That’s it! Just keep going!”
Now satisfied with her form, Alkim watched the hypnotic movements of her mams for a bit. He wondered if he was the only one staring at his bombshell housemate. Sure enough, a quick peek at the mirror confirmed his suspicions.
Not like purple-haired Asian women with giant tits are an everyday sight.
Nearly a dozen heads swiveled back to their machines, or their phones, once Alkim started scanning the room. Apparently, no one wanted to be caught checking out what they all knew they were checking out.
Figures. They probably think I’m her possessive boyfriend. God, if only.
With a final grunt, Kate finished her last rep and dropped her dumbbells to the ground.
Wait, how many was that? Too many? Shit, was I supposed to be counting?
“Fuck me, I think I’m done with chest stuff. Can you put those away for me?” Kate asked, taking another swig from Alkim’s bottle.
She’ll never be done with chest stuff. “Yeah, no problem.” Alkim was already reaching for the dumbbells.
“Thanks. Guess if I’m going to be carrying all this extra weight, I should probably do some back exercises, huh?” She stretched her arms behind her back, thrusting out her tits at him, her overstuffed cleavage jiggling endlessly. When he remembered to look at her face, he found her smirking at him.
“Uhhhh, yeah, back exercises would be a good idea. Meet me at the lat machines.”
“Cool, I’ll clean the bench, and meet you there.”
Fucking what? She’s gonna clean off MY sweat?
“Alright,” Alkim said with a tone that he hoped conveyed absolutely none of the confusion he felt. He thought she hadn’t noticed the sweat, but now he was wondering if she just suddenly didn’t care anymore.
He set up his weights on the lat-pull-down machine, but his thoughts were all on her. Normally, Kate never volunteered to clean anything, but lately she had seemed much more vigilant about cleanliness at home, which was also completely at odds with her laying down on top of the sweaty bench. Letting him look at her was normal for her, but not in public, and not after how upset she’d been about her enlarged tits only an hour prior. The inconsistencies in her behavior just didn’t add up.
What the hell is going on with her?
Alkim decided she must be going through something more serious, and the weight gain was probably just a side effect. A very, very, very sexy side effect. If Kate was having problems beyond the inconvenient largeness of her boobs, they could talk about them after their workout.
