Sweat, Baby, Sweat



	It was a sunny March day, and Meghan “Valkyrie” Castellano was heading down to the gym. Team Rainbow had a magnificent gym located within walking distance of the bunkhouse, mess hall, and Operations. All of the operatives were required to clock at least six hours a week in the gym, but some were more vigilant about it than others. Meghan was a gym rat, in evidence by the team’s propaganda poster of her flexing one tattooed arm. She had more tattoos, but where they were, normally people wouldn’t get to see them. Around her face she carried a bob of blonde, almost-white sun-bleached hair, while her eyes were shockingly blue. 
Eliza “Ash” Cohen, on the other hand, was not really into working out. She had a noticeably smaller build than Meghan, especially in the arms and abs; they happened to share the same height at 5’7’’. Ash was Israeli and it showed in her accent, her mannerism, and her circumcision. She was heading to the gym too, although she mostly just wanted the hours clocked up. She had a braid of brown hair that went past her shoulderblades, a relatively sharp jaw for a woman, and a pair of pouty pink lips.

Being a counter-terrorism operation, Team Rainbow wasn’t exactly full of jokesters. It was a tough-as-nails military operation, and the women it employed reflected that. They didn’t waste time or breath, but they certainly weren’t emotionless iron walls. So when Meghan waved at Eliza, the Israeli waved back. The girls walked together down the lightened hallways of the Rainbow base. Meghan was from California, and her American-ness came out in her optimism and, relative to other operators, gregariousness. She frequently shouted into the earpiece because she was the sort of person who really got into whatever she was doing, and wasn’t all that comfortable in silence. Still, she recognized there wasn’t much to talk about, and if Eliza wanted to just walk, well, she tried not to let it bother her. Eliza was certainly her opposite in more ways than one, because as SWAT, Ash had to know how to just shut up and wait for days on end for a target of opportunity. Eliza was one of the rare operators who sometimes spoke quietly enough that the microphone didn’t even pick up her voice. Meghan fidgeted as the two women walked together in silence, and Eliza noticed.

“Don’t be so nervous,” she said mildly. 

“Easy for you to say,” Meghan said with a laugh, before her brain actually processed that the statement she chose would require a little more exposition. She clamped her mouth shut and hoped Eliza wouldn’t notice or care, but she did.

“Why do you say that?” she said, still looking straight ahead. She shifted the strap on her shoulder which was supporting her gym bag, as it started to chafe her skin beneath the relatively-heavy uniform.

“Um,” Meghan managed to fill the empty space with, as she scrambled. What she was going to say, in her head, was easy for you not to be nervous around such a beautiful woman. She had the confidence to say that to most girls, had actually made it halfway before her brain shut her up… it was easy to say that to those women who fawned over her muscles, those women who were already in her bed before she had to speak. But even beyond knowing that workplace relationships were risky, she respected Eliza, and didn’t see her as a piece of meat to bounce on her dick. Meghan rubbed the back of her head. “I’m always nervous. Comes with being an intelligence operator and knowing that you could be being watched.”

“That doesn’t sound healthy,” Eliza said, quirking her eyebrow. “Do you really walk around thinking that someone is spying on you?”

“Only because of experience,” Meghan finished, satisfied with her recovery from the flub. 

Eliza grunted assent. “This job does change the way you look at the world.”

They made it to the gym. In such incredible physical shape as they were, even fast-walking a half-mile didn’t even make them breathe harder than usual. The gym only had a couple other operators in it, because it was such a beautiful day outside, nobody wanted to be cooped up. The Californian and the Israeli on the other hand, the operatives from some of the warmer places on earth, had gotten their fill of sun and sand in their own youths. Sweat was good, but heat fatigue was very bad. 

The workout equipment was set up in long rows so that operatives could simply slide over to the next machine when they were done, and the idea was that when they got to the end of the row, they’d completed a full set and they were ready for a break. Also, the rows were set up so that two identical machines had their backs together, while the fronts of the machines faced towards the face of the other row. That way the operatives could look at each other and talk while they worked, not to mention compare form and even compete with each other.

	Ash and Valkyrie each signed in with little identification cards, which is how the system kept track of how many workout hours you spent. Of course that was no guarantee that you actually pumped iron while you were in there, but the sort of men and women who signed up for the Armed Forces usually couldn’t help themselves if you gave them something heavy to lift and a person to show off for. They were encouraged to go there as a group for that reason, although there was always the danger of showing off too much and straining something. Usually, the women were more level-headed than that.

	Then they headed to the changing room, which was pretty small, only having about fifty lockers along the walls. Rainbow Team wasn’t known for having the biggest roster, it was known for having the best. The locks were high-tech electronics, so the doors stuck out at a 90 degree angle from the wall unless someone had actually put stuff in them and locked it with their ID cards. With operatives potentially carrying top-secret-level information on their persons, it was best to be overprepared. Meghan got herself undressed as coolly as she could, but couldn’t stop herself from glancing over to Eliza. The Israeli took her bottoms off first, stepping out of her pants as Meghan watched. Her ass was tight and beautiful with gorgeously-round buns, her thighs faintly-muscled, her legs perfectly-proportioned. A pair of white panties stretched around her rear, which Eliza pulled off casually and placed in a neat pile on top of her pants. Then she crossed her arms in front of her and pulled her shirt off over her head, exposing her big, round jugs, constrained by a white sports bra. Meghan could see the edges of her breasts from behind, and went pink in the cheeks. Her own breasts were a little bigger, even, but it still gave her an electric thrill to look at a woman’s tits. A thrill that she felt, of course, in her cock. Without warning her 5-inch penis sprung a half-chub and she turned away, blushing harder and getting herself undressed quickly to mask that she had been watching. She got naked down to her underpants, then pulled off her panties and launched them into the locker like an elastic band. She turned around to find Eliza standing there, equally nude, their large breasts held back by heavy-duty bras. Eliza’s face betrayed the slightest hint of a smile before she blinked and turned around, giving Meghan’s eyes a split-second to glance down at her fellow operative’s dick. Like her own, it was five inches, but unlike hers it was circumcised, and to her vision it looked a little bit like Eliza was turned on. But no, it was just at trick because her glans was exposed. Meghan cleared her throat and finished changing.

	The two women walked out into the gym looking their best, Meghan wearing a tight black Rainbow Team outfit that showed off her toned curves, Eliza wearing the same uniform in red. The gym shorts came down to mid-thigh, leaving most of that creamy flesh on display, while their tops left their armpits and shoulders exposed, their bras hidden beneath the straps and fabric. 

	Before the workout started, they weighed themselves. The scale was right in front of a mirror, and both girls checked themselves out as they stood on it. “One fifty six,” Meghan said happily, jumping off the scale to let her silent partner step up “One forty… five,” Eliza said, appending the five. The scale said 138 but she fudged it up to 140 and halfway through her sentence got a sudden urge to just lie. She didn’t like being almost twenty pounds underweight compared to Meghan. She had been proud of her body, until now. 

	The workout started on the yoga mats. They were foam, but with an ultra-high-tech polymer coating that made it so you were less likely to get rug burns, rather than that plastic shit (and fucking velcro) you probably had in high school. Eliza was the clear winner here, going through her stretches faster and more cleanly than Meghan could. Valkyrie’s body was terrific, a body most men would kill for, but the extra muscle made it harder to reach the extreme angles that Eliza made without effort. Still, Meghan felt her body stretching, and it felt good, especially being able to take quick glances at Eliza’s body. The Israeli was downright lithe for an operator, although she had wide hips and an impressive chest that nearly matched her own. Eliza was conscious of how juicy her tits were compared to the rest of her body, while they did a better job matching Meghan’s frame. Still, the girls were actually the exact same height, so she felt better about not having freaky-huge jugs now that she saw Meghan’s mammoth mammaries jiggling in the supportive cups. Meghan watched Eliza as the woman bent to the side at the hips, her shirt pulling up her torso and exposing a little more of her midsection. Eliza had a nice pack of abs, although Meghan’s was far more well-defined, and even called attention to itself with an intricate tattoo that snaked down her arm, shoulder, and right side of her body. Where the tattoo ended, well, only girls Meghan took to bed could say that for sure. Eliza also had to tuck the end of her braid into her cleavage to keep it from moving around too much; that sort of thing could easily get caught in the machines, which was one of the reasons for the tight clothing.

	The other reason was that recreational sex was encouraged among operators. It made them tighter as a unit and kept them physically fit in the ways that actually mattered, moving around and keeping coordinated. Weight-lifting machines were great for strength and endurance training, but absolutely awful for coordination. In fact, you were liable to get a little off-balance in parts of your body, but Meghan had taken extra-special care to ensure she worked all the major muscle groups equally… even if she did want to spend most of her time in the bicep curl at the public gym, flexing while other girls gazed at her. Those were the kinds of girls she didn’t mind showing off for, and being loose with her language, implying that she’d fuck them if they worshipped her body properly. Eliza wasn’t like that. It was more like a rivalry for one thing, a friendly one anyway. They had worked out together a few times before over the last three years, but they had never approached each other about maybe seeing each other outside the gym. 

	The one place Meghan had her beat was in spreading her legs really wide and then lying down on the floor. Her abs and thighs were perfectly suited for this, although she did feel an intense pain in her groin as she stretched. It was the one time she could overcome her in the pre-exercise stretch, so she pushed it a little harder than she would if she was alone. That was, of course, the point of doing it as a group.

At last they were finished, slightly pink in the cheeks, breathing ever so slightly harder. They shared a grin, sat down in machines opposite of each other, and started.

	The workout began with the legs. It was found that operatives liked to start there, so their legs got a break while they did their arms before leaving the gym. Both women looked at each other, while trying not to look like they were looking at each other. It was a shoulder press, with bars above your head that you pulled down on. It was a great workout for a large part of the upper body, especially the shoulders and triceps. Not only that, Meghan thought, but it lets me flex. Makes me look just like that poster. She grinned. One time, a girl Meghan brought home ran her dainty fingers over her tris and cooed, which made the big strong operator flip her over and give her a good dicking right there. Just the memory of that made her dick move a little in her pants.

It was generally true that larger bodies meant larger muscles, and she was quite confident that she could out-do Eliza when lifting weights. When it came to stretches and flexibility, though, Eliza had been the clear winner. Ash already looked like a gymnastic athlete without being one. And even then, it wasn’t universally true that a bigger body meant stronger. Meghan pushed the weight-selector pin a little heavier than normal and sat down on the bench, her thick thighs straddling it, and legs coming up under a stationary counterweight. She smiled as she settled into her arm-flex pose and compressed her arms, her back rippling. Instead of feeling her muscles stretch now, right when she was using them, they were already stretched nicely from the poses on the mats. Within three reps the sensation was gone. “Ah,” she grunted, letting the heavy black plates gently fall back down so that they made only the faintest clatter as the stack rested atop the rest. Fifteen reps, not exceptional. She moved the pin, selecting a higher weight. She wanted to prove that she really was the stronger of the two.
	Eliza tried not to make it a contest. Because, of course, she couldn’t win a contest. Her arms were noodles compared to Meghan. Meghan was no professional body builder, but her biceps were still impressively beefy, especially for a woman. Eliza found herself staring at Meghan, and the girls’ gaze met for a moment before breaking away. Eliza had to content herself with doing thirty reps of a lower weight, and confided in herself that it was equal to Meghan’s display.

	They moved through the machines over the course of half an hour, each girl doing her best to out-do the other without pushing it too hard. Meghan’s biceps were burning by the time she reached the leg machines, while Eliza had taken it easier and was careful not to push herself past her comfortable limits, as Meghan had. 

	Eliza bit her lip as she watched Meghan settle down into the opposite machine. This one was simple: Straddle a bench, then try to bring your knees together. Pads kept them from touching, and the pads were connected to the weights. This exercise worked out your inner thighs, which for Meghan were rock-hard. She had a girlfriend at home who complimented her on them often. Eliza’s legs were in better shape than her arms, as she had been doing a daily running routine for the last few years. For Eliza, the contest came down to this one. And that meant Meghan had to win it, too. 

	Meghan grunted as she brought the plates together. The weight behind her was prodigious. She stared openly at her partner, those piercing blue eyes gazing into the other’s. She panted as she crunched, making the machine slap together, an impressive feat at that level of weight. Eliza admired her partner’s strong-looking thighs. She had no doubt that Valkyrie could crush a watermelon between her legs if she wanted to, and wondered exactly what that would look like. She had seen videos where girls destroy things with their tits, by dropping them on tin cans and flattening them, or crushing watermelons with a big heave of their chest. She blinked out of her stupor, realizing she had zoned out for ten seconds while staring at Meghan’s thighs. Her eyes flicked up to Meghan’s, and she paled slightly. The other operator was looking right at her with a victorious grin on her face. Far from pale, Meghan’s complexion was rather pink in the cheeks. Eliza pursed her lips and looked up at the ceiling, trying to make Meghan look up there, but it was too late. Eliza’s pants were firmly tented, her five-inch girlcock doing its best to stick up to her belly button. “Ufff,” she breathed hard, squeezing her legs together to make the fabric tent itself more naturally, but she hadn’t set the selector pin and the single stack of 5 pounds shot upwards and clanged into the top part of the machine, making a galling ringing sound. Meghan let out a burst of laughter, finishing her set of 30. Then she released her legs a little too quickly, her muscles eager to relax, and the stack of weights clattered loudly against the rest of the stack, making her jump with surprise. When she looked back up, Eliza was staring at her with a little less shame than before. 
Eliza reached down and pushed the pin in one block higher than Meghan had done, and over two gruelling minutes, completed her own set. Of forty reps. Sweat was pouring down her forehead as she did, and every muscle was clenched the whole time. Her erection didn’t go away, if anything it got more furious as her balls were rhythmically squished by her thighs. As she stared, Meghan’s cock rose too. The Californian’s face went red as her dick matched Eliza’s, and soon after, they were sitting there, workout finished, and horny as hell.

“M-maybe we should…” Eliza said, trailing off, biting her lip, her eyes nervous and fleeting.

“Maybe we should,” Meghan replied firmly, standing up, letting the tent stick out plain as day. She had gotten a boner while looking at her friend, should she really hide it? No, she should be confident in her desires, even if her body had betrayed her.

One minute later, they found themselves in the steam room. The temperature of the air was noticeably warmer than the human body, while the air saturation of water was at 100%, which was done so sweat could not evaporate. In the steam room, of course, they had plausible deniability for what they were doing, as long as they sat in the corner away from the door. Nobody ever came in here anyway.
“I’m… in a relationship…” Eliza said as Meghan shoved her up against the wall and stuck her hands down her pants.

“Oh really?” Meghan said seductively. “Well so am I.”

“I’m Jewish too,” Eliza moaned, Meghan’s fingers curling around her hanging sack. “I’m not supposed to have sex before marriage.”

“You really believe that?” Meghan said. Cali-fornication wasn’t exactly known for its piety. “Well then we’ll just have to keep things Catholic,” she reasoned. She jumped up on the boards at the back of the room and patted beside her. Eliza, hard as hell and feeling pre bead on her tip, took a moment to decide, then another moment, and finally joined her, bumping their hips together. Both women were completely naked now, the steam filling their lungs pleasurably.

“No penetration, right?” Meghan said, reaching out and grabbing her partner’s tool again in her hand. The dick was small, but her hand was small too, and it fit well. Eliza didn’t reply, just letting her mouth fall open again as she panted, her body sweating but finding no relief.

Eliza eeped as Meghan kissed her shoulder, then upper shoulder, then neck. She pulled away just slightly, but flexed her thighs in such a way that her circumcised cock pushed deeper into Meghan’s clenched fist. The thicker woman smirked and began to stroke from base to tip, just using her thumb and two fingers to start. Her eyes screwed shut. She was obviously ridiculously sensitive.
So it came as a surprise when Eliza’s hand reached back and she grabbed Meghan’s erection, giving it a few firm strokes too. “I can give as good as I get,” she said quietly, and matched every one of Meghan’s motions. As a result, Meghan found herself doing just what she herself liked so that it would be reciprocated on her, like pushing her thumb into the glans, or tickling the seam of her balls with her pinky (when Eliza did that, her asshole twitched). She laid back against the wall with a grunt of satisfaction as her partner jerked her off. It felt nice to lie on the wall and let her muscles really relax. Still, she kept up her manipulations, eventually sliding a few more fingers over Eliza’s cut dick and gripping it harder, making the motion less continuous and more of a jerk. Just that change alone made Eliza’s head jerk back and thump into the wall slightly. “Ow,” she said distantly, an automatic reaction than actually being in pain. She blinked her eyes a few times, and Meghan thought she was batting her lashes for her.

	“Fuck you’re sexy,” Meghan breathed, licking her juicy wet lips.

“You think so? I think you’re sexy too,” Eliza said, not very good with eroticism. Meghan’s eyes traced down Eliza’s body and settled on her breasts.
“You bet I do,” she said, reaching her free hand over to cup the woman’s hanging chest. Eliza’s expression weakened and she let her mouth hang open again as the strong fingers cupped her breasts. She reached over and did the same to Meghan’s chest, fondling her and pinching her nipple.

“Ow,” Meghan replied with the same dull tone as Eliza had said it, but Meghan was grinning from ear to ear. “Guess I can’t kiss you on the mouth either?”

“…I think that would be okay,” Eliza said, puckering her lips and leaning over.

First their lips touched, then they merged, then tongues began to slide together slowly and gently. Each girl was painfully hard, and although Meghan was feeling particularly turned-on and sensitive today, well, Eliza just didn’t have the same level of experience as she did. The Israeli’s eyes screwed shut and she let out a pained gasp as her orgasm came upon her, her little cock squirting a few bolts of cum onto her face and chest. “Ahh… ahhh…. Ah…” she panted, a bead of drool trailing down her lower lip. “That feels good…”

“It does feel good,” Meghan said, flexing the muscles in her cock and making it just a little harder. It only took another half-dozen strokes for Meghan’s own orgasm to rock her body; she gritted her teeth and gasped as ropes of cum pumped out of her dick and onto Eliza’s hand.

Seductively, Eliza raised the hand to her mouth and licked the spunk off. “Mmm… tasty.”

“I… eat a lot of fruit,” Meghan murmured, rubbing the back of her head and looking down at the floor.

“What does that have to do with anything?” Eliza laughed, not waiting for an answer before getting down on her knees and wrapping her juicy breasts around Meghan’s still-hard cock. “I can’t take it into my mouth, but I can still do this,” she offered, lifting her hands up and squeezing them all around. Meghan stiffened and grunted, nodding quickly.

“Yes please.”

So Eliza began her first titfuck, sliding up and down slowly. Her lithe dancer’s build made her good at this, as did her massive breasts that were perfect cushioning. It felt strange moving her legs and body that way, but she did without complaint, a smile coming over her face as she realized she was actually rather good at it, judging by Meghan’s body language and constant swearing. 

“Fuck! Your tits are so big,” she moaned. “They look so good on you. What size cup do you wear?”

“F,” she replied, and Meghan groaned again.
“That’s so hot.”
“My cup-size is hot?” Eliza said, continuing to slide up and down, squashing her tits together.

“Yes,” she answered simply, her cheeks sliding up as another grimace overcame her and she shot her second orgasm right on Eliza’s face. Eliza giggled and wiped it off with her fingers. 

“That was quick, you must have really liked my breasts,” she said, now fluttering her eyelashes seductively, since she noticed how Meghan reacted so well to it last time. 

“Yes,” she answered again, then laughed. “Come here.”

Meghan pulled Eliza up into her lap and they began to make out again, softly and tenderly, while their hard cocks rubbed together. Carefully Meghan’s fingers wrapped around both dicks and started to stroke, sliding her tongue past Eliza’s lips as she pumped, peeling back her own foreskin but not making much of an impact to the circumcised girl. They broke the kiss and Eliza looked down. “I’ve never seen one that isn’t cut,” she said. “It kind of looks like a gross worm.”

“Hey, that’s not nice!” Meghan said after a burst of laughter. The women lapsed into a comfortable silence as the operator stroked them both off, their hard cocks throbbing against each other. The skin was delightfully warm and not just because they were in the steam room. Eliza humped gently into Meghan’s hand, but not too hard, as she trusted her partner to bring them off in time. Her hips just naturally wanted to move, especially since she had a nice tight hole to thrust into. Eliza came first again, splattering her cum onto Eliza’s belly. 

“Ahhhnn,” she groaned, her eyes crossing as the second orgasm went through her powerfully.


Just like before, having her partner cum suddenly made Meghan nut. This time she kept her mouth open and caught the jizz in her mouth.
“C’mere,” she said, not even wiping the spunk off her fingers before grabbing Eliza around the back and kissing her deeply, snowballing the cum into her mouth. The girls laid down, Eliza on top of Meghan, making out for a few minutes before finally Meghan felt Eliza’s cock nudge at the bottom of her balls. She grinned. “Go for it.”

“I can’t,” Eliza whispered.

“Sure you can,” Meghan said, kissing her nose. “I’ll help you.”

Eliza whined as Meghan sat up and put her down on her butt, her erection sticking up from her thighs. Meghan sat down on top of it, her asshole crinkling as it molded around the dick. Meghan’s expression tightened for a second but returned to normal once the stretching was over. Gently, very gently, she began to rock herself up and down, even wagging her hips back and forth while Eliza’s hands sank into her toned butt. “Oh fuck,” Eliza swore, her voice girlish.

“I haven’t heard you swear before,” Meghan teased, looking back over her shoulders.

“Well you’re just… it’s so… hot…” Eliza said, brow clenching and eyes shutting as her mouth dropped open and the most intense orgasm yet coursed through her. She didn’t even know how her body managed to find that much cum inside itself after cumming twice. She shot six strings into Meghan’s ass, not a large orgasm except by the standards of a third one in fifteen minutes. Her cute little girlcock was completely kaput after that, not even managing to stay in Meghan’s butt as it rapidly softened and retracted. “Oh, it’s little again,” she said solemnly, laying it in her palm and letting it slide off. 
“Dicks will do that,” Meghan said, standing up. She was still hard, but after a handful of seconds, her cock went back down. She didn’t want another orgasm after having three excellent ones. “Come on. Let’s go get changed again, we’ve been in the gym for ages.

“Well, there’s no going back after that,” Eliza said, thinking of her lost purity. She shrugged her shoulders. Here she thought it was going to corrupt her or make her a bad person or something, that stuff was drilled into her head from childhood. Now an adult, these concerns were more easily banished as nonsense. She slid her arm around Meghan’s waist and they walked out together, displaying their soft cocks proudly between their thighs.
