Cow Spot

"It's..." Madeline stuttered, trying to keep her voice even as she looked back over her shoulder, staring at her ass in the mirror in disbelief. "A c-cow spot?"

"That's right, babe," her girlfriend Arizona replied, the expression on her face distinctly closer to a smirk than a smile. "A cow spot. What do you think?"

"W-well... um... it's..."

Unbelievable. Ridiculous. Embarrassing. That was what Madeline was thinking. But mostly, she was focused on trying to keep herself under control. Her stomach was in knots. She was blushing, and not all the heat in her cheeks was shame. And that prompted the urgent question: did her girlfriend know? Was that why she was doing this? No. No way. There was no way she could have figured out Madeline's fantasies. That hadn't happened. That couldn't happen. Which meant Madeline needed to act normal. But what did 'normal' mean, when your girlfriend had just tattooed a large, unmistakable cow spot on your ass?

It wasn't that she didn't trust Arizona, of course. If she didn't trust her, she wouldn't have let her give her a tattoo. They hadn't really been dating long, but Madeline had no reason to distrust her tall, blonde girlfriend. Quite the opposite. With her side shave and punk tattoos, Arizona radiated the kind of dyke energy that Madeline felt safe with, and moreover, they were both trans. That made it easy to be at ease together. Plus, Arizona was just so damn hot, and so damn cool. She was a tattoo artist! Madeline had always admired tattoos, but she'd never quite plucked up the nerves to go and get one before. So, when Arizona had requested to practice on her, she'd shyly, but eagerly, agreed.

The follow-up request to practice on her ass had left Madeline wildly flustered, but not flustered enough to back out. Having to get totally naked and lie out on a table for Arizona to stare at sure had been an experience, though. More than once, Arizona had needed to chide her to keep still and not squirm. But she just couldn't help it. Madeline didn't dislike her body, exactly, but it was a little difficult not to be self-conscious next to Arizona. Her girlfriend was in great shape, and was more than happy to show it off. Her habit of walking around her apartment wearing nothing but a sports bra above the waist so that she could show off her abs had left Madeline drooling on more than one occasion. Madeline, by contrast, was on the chubby end of the spectrum. She wasn't quite so eager to show herself off, although happily Arizona had made no secret of how much she adored Madeline's soft, welcoming tummy, and the plump, round ass to which she'd turned her tattoo machine.

And left her with a large, prominent cow spot.

"Well?" Arizona prompted. She looked so pleased with herself.

"It's..." Madeline tried to think of something really tactful. "It looks really good! Nice, uh, lines. Seems like you did a really neat job. Aren't tattoos usually supposed to be all red and stuff at first?"

"Like I said earlier," Arizona replied. "Special ink. Real special. Hard to come by. I think you'll love the way it feels."

Madeline couldn't fathom what that was supposed to mean. "But, um... why a c-cow spot?"

"Hm? Don't you like it?" Arizona asked sweetly.

"I didn't say that!" Madeline blurted out, and then giggled awkwardly. "It's just, um, quite a choice, you know?"

Her girlfriend shrugged. "I thought it'd suit you. Figured you'd get a kick out of it."

Madeline could feel the tips of her ears turning red. She had to fight the instinct to reach down and cover herself. "W-why would you think that?"

"Well, don't you like cows?" The irrepressible smile on Arizona's face was proving impossible to read.

The only response Madeline could muster was an awkward, stilted squeak. What kind of question was that? What was she supposed to say? 'Yes'? 'No'? 'I like them a normal amount'?

"Anyway," Arizona said, her voice suddenly dropping low as she stepped closer to Madeline. "What about my payment?"

"Your payment?" Madeline was suddenly confused about something altogether different. "I thought you were just doing this to practice? But, um, sure, how much do I-"

Arizona interrupted her with a giggle. "Not that kind of payment, silly. What I mean is... don't I get to enjoy myself a little, after spending so long staring at my hot, naked, curvy girlfriend?"

"Oh." Madeline started squirming again, and giggled too. "Right."

She always tried to be seductive and confident with Arizona, but it never worked. Her girlfriend always seemed to know exactly what to say to leave her a hopelessly flustered puddle. Fortunately, the buff girl was more than happy to save Madeline from her own indecision. She slipped an arm around Madeline's waist and pulled her, gasping, against her body. Her bed was just in the next room, and as she led Madeline there, Arizona didn't hold back from groping her, letting her hands roam over her stomach and sink into her wide, soft hips.

"Babe!" Madeline panted. "You're being so f-forceful!"

"Can you blame me?" Arizona was grinning wildly; that cocky, lopsided grin that always sent a shiver down Madeline's spine. "I'm so worked up, just thinking about what's gonna happen?"

"What does- ah!" Madeline yelped as Arizona roughly pushed her back onto the bed. "W-what does that mean?"

"Oh, don't worry your pretty head about it."

All of a sudden, Arizona was on top of Madeline, straddling her.

That was all it took for Madeline to stop worrying about it. The sight of her girlfriend looming over her, grinning wolfishly as she pulled her sports bra off over her head, drove every thought from her mind that wasn't about sex. Madeline was already rubbing her legs together. She loved it when Arizona got dominant with her, and Arizona knew it. The embarrassed heat in her cheeks was rapidly metamorphosing into something quite different, and spreading throughout her body.

Within moments, Arizona had shucked out of her hotpants. Her panties were next, and once she was naked, it was even more obvious how turned on she was. Madeline whimpered at the sight of her large, hard girlcock. She was now just as turned on as her girlfriend, her own, smaller girlcock straining and pressing against the taller girl's body. Before she could take more than a moment to compose herself, her girlfriend was pressing her lips against hers in a passionate, intense, hungry kiss that left Madeline gasping for breath.

"Oh wow," Arizona purred, her hands reaching to cup Madeline's tits. "These are looking good. I can't believe it's already working."

"H-huh?" Being groped was making it difficult to think, and Madeline couldn't figure out what she meant. "What is?"

"What, don't you think they look bigger?" Arizona was smirking, and leering nakedly at Madeline's chest.

Madeline looked down. Come to think of it, they did look a bit more full than usual - but it was hard to tell, with Arizona's hands all over them. "Well, um, I guess, but why would that be- ah!"

She saw white as Arizona turned her attention to her nipples, taking them between her fingers and massaging them. Fuck. They were suddenly so sensitive. Madeline immediately forgot what they'd been talking about.

"Yeah. Yeah, definitely bigger. I should know. I'm an expert." Arizona winked. Normally, she paid attention to Madeline's whole body, but tonight, she was totally focused on the plump girl's chest. "God. This is so hot."

"It's... hnngg... f-fuck." Madeline had been on the bed for maybe a minute, but she was already squirming like crazy. Only Arizona's weight straddling her hips was holding her in one place. She didn't mean to, but she couldn't help it. Her tits, her nipples, were on fire.

"Yeah, babe?" Arizona giggled, showing absolutely no inclination to offer mercy.

"They're... so... s-so..." Madeline couldn't think. She couldn't form one single thought, before it was blown away by shocks of pleasure from her tits. Arizona was dangerously skilled with her hands. She knew exactly how to tease Madeline's nipples, exactly how to grope her tits until she was in a frenzy of lust. But this was more than that. The way her body was responding to the touch was way, way beyond anything she'd ever felt before.

"So what?" Arizona teased, plainly reveling in Madeline's speechless, pleasure-drunk state.

"S-so... fuck..." Forming the words in her head was a colossal effort, to say nothing of getting them past her lips with the dissolving into hopeless moans. "So... fucking... sensitive."

"Good." Arizona's giggles were turning breathy. She was too eager, too turned on, for detached teasing. "Then, how about..."

Before Madeline could manage another word, Arizona put her lips to one of Madeline's nipples and started sucking. Immediately, Madeline's back arched, and she found herself involuntarily pressing herself up against her girlfriend. Between her legs, she was still completely hard, and now, she started dripping precum from the tip of her cock. Suction was a whole further dimension of pleasure. It was more intense than Madeline could have ever guessed, even accounting for how good Arizona's hands had felt. There was nothing she could do but throw back her head and moan.

"Mmmff," Arizona moaned, the sound muffled in Madeline's chest. She was grinding her cock against Madeline's stomach, her arousal more plain than ever. Madeline didn't know why Arizona was so horny, but she knew that she herself was more turned on than she'd ever been in her life. Her tits had always felt good, sure, but nothing like this. Not even close.

The more Arizona suckled, biting and nibbling teasingly a little as she did, the more a new, unfamiliar sensation started to well up inside Madeline's chest. It was a kind of pressure, warm and insistent. It felt good, but it only made Madeline more and more needy the more it built. As Arizona's tongue lapped at her teat, her sensitivity peaked, and suddenly she couldn't bear the thought of Arizona stopping. She needed her girlfriend to keep sucking. She needed the attention. She needed it, because she was so close, so close, and...

And then Arizona stopped.

"No!" Madeline whined, arching her back again as Arizona raised her head. "P-please..."

"Yeah?" Arizona laughed, panting. "Please what?"

"I'm close!" Madeline moaned. Even without Arizona's lips around her nipple, her body was wracked with pleasurable, frustrating little aftershocks. She was past caring about how embarrassing her begging was. "Really... feels so good! I need m-more."

"Wow, babe. I don't think I've ever seen you this shameless before."

Mercifully, Arizona didn't draw out her frustration too much longer. Instead, she put her hands back on Madeline's tits and started groping them again, squeezing them in a pleasurable rhythm as her fingertips teased her girlfriends nipples.

"Yes!" Madeline panted gratefully. Arizona's hands quickly had back on the edge again, riding the unfamiliar ecstasy that had been building within her. It was just like the sensation of a growing orgasm, but entirely in her chest.

"This is so fucking good," Arizona breathed. "God. Fuck. Cum for me, babe."

Madeline screamed with pleasure as the orgasm hit her. She'd never felt anything like it before. She'd never been able to cum with just her tits before - and not only was it a first, it was maybe the most intense orgasm she'd ever had. The sense of release that accompanied it was incredible. She closed her eyes, arching her back, letting it all wash over her. She couldn't have guessed how much time passed before she slowly returned to her senses - brought back by the sound of her girlfriend giggling manically.

"W-what?" Madeline opened her eyes, growing embarrassed once more now that the fog of her own arousal was passing.

Arizona just pointed, wordlessly, at her chest.

Madeline looked down, and gasped.

There were droplets of milk dripping from her nipple.

***

At first, Madeline didn't think much about the sudden bout of lactation. It was embarrassing - even if it was a little hot, too - but it didn't seem that weird. Probably, it was just down to something with her hormone levels. That would also explain why her tits seemed so swollen. It simply wasn't a big deal. Of course, that didn't stop Arizona from milking plenty of fun out of the incident. She brought it up just about every chance she got, and it never failed to make Madeline blush. Especially when she joked about how fitting it was, what with her new cow spot tattoo.

Still, she didn't think much of it at all. Not until a couple of days later, when she woke up in her own apartment, and her tits weren't just 'bigger'. They were huge.

That wasn't all that was different, as she quickly established, looking herself over in the mirror. Her hips had grown too, giving her something much closer to an hourglass physique than she'd ever had before. Her thighs were thicker and shapelier, and her stomach seemed a little tighter too. Her tits were by far the most prominent of her new features, though. Once look was all it took to ascertain that none of her bras were going to fit. It was the kind of change Madeline would have been pleased with, if it hadn't happened overnight. Plus, was there something different about her face? Her nose seemed a little different. Or was it her ears? Madeline couldn't quite put her finger on it.

There was one more thing she noticed, as she turned around and around in front of her bathroom mirror. It was Madeline's new tattoo. It was different. Rubbing her sleepy eyes to make sure she wasn't still dreaming, Madeline carefully and deliberately counted four cow spots. There was the one she remembered seeing, a small one opposite, one a little lower on her thigh, and one a little higher at the base of her spine. Had her spots... multiplied? No, that was crazy. Impossible. She must have just missed the other ones at first. For the past two days.

Madeline grabbed her phone and called Arizona, who had slept at her own place that night.

"How many spots did you tattoo on me?" Madeline asked, the moment Arizona picked up.

"What?" Arizona sounded sleepy too. "Oh! Are there more?"

"That's what I'm asking!"

"Well, how many do you count?"

Madeline counted again. "Four."

Arizona laughed. "Well, I guess that's how many I gave you, babe."

After they hung up, Madeline started to wonder if she was imagining things. She resolved to try and go about her day as normal, but that plan quickly encountered another obstacle: her clothes really, really did not fit anymore.

It wasn't just her bras. She tried to put a t-shirt on, but even her loose-fitting ones were straining desperately to fit over her new chest. None of her jeans or pants were a match for her hips, and she ripped a pair of panties in her futile attempt to put on underwear. After going through her entire wardrobe looking for a half-presentable outfit, Madeline gave up. Clearly this was just a dream. Or something. She picked up her phone and texted her boss, letting him know that she was sick, and wouldn't be able to come in to work today. And with that, she let herself fall back onto her bed. If this was a dream, she might as well enjoy it, right?

Fittingly enough, at that moment, Madeline realized something else: she was really, really horny.

Madeline wasn't embarrassed to find herself feeling a little pent up. That was normal enough. But the insistent, pressing heat that filled her body went beyond anything she usually felt. She wasn't troubled by it though. Dream or not, she didn't have to go into work today. Which meant she had plenty of time to enjoy herself.

As she settled herself back comfortably on her bed, she reached down and started to stroke herself. Her body immediately responded to her touch, and as Madeline started to ease into the rhythm of her self-pleasure, her mind started to drift, searching for fantasies she could use to urge herself on. One fantasy in particular presented itself, making her blush even though there was no-one around to see. Her secret, embarrassing love for porn and fantasies about being treated like a cowgirl or a human cow had always been one of her go-tos when she wanted to get off, and the tattoo Arizona had given her had taken the kink to another level.

Soon, Madeline was lost of her fantasies, squirming and gripping the bedsheets with one hand whilst the other worked up and down along the shaft of her hard, throbbing girlcock. Only... it felt like something was missing. She was feeling good, of course, but there was some kind of yearning, some kind of craving, she wasn't quite hitting. After a few more minutes, Madeline's mind turned towards the deeply embarrassing, deeply hot memory of what had transpired between her and Arizona on their last date. Tentatively, she lifted her free hand from the bed and brought it to her chest, gently squeezing one of her own, newly-swollen tits.

"F-fuck!" Madeline gasped, as an immediate explosion of her pleasure hit her. One touch was enough to bring her the kind of pleasure she'd never even been able to imagine before. Her tits were so sensitive! Somehow, they'd become even more sensitive than they had been a couple of days ago. At any other moment, that might have been concerning. But, turned on as she was, Madeline found herself incredibly grateful for the new feeling. This was what she needed. What she'd been craving.

Within minutes, Madeline was utterly drunk on the pleasure her new body was able to bring her. She barely noticed as she took her hand away from her dick, bringing it, too, to her chest, so that she could play with her tits all the more. The raw, visceral bliss was enough to make her light-headed, and more than enough to banish any sense of shame she might have had. Madeline barely even noticed as droplets of milk started to seep from her nipples, dripping down her body and onto her bed as she squirmed and writhed ecstatically. She couldn't believe she'd never thought to touch herself this way before. It was so good.

It wasn't long before Madeline found herself eager to explore just how far she could push her new limits, and just what her new, incredibly curvy body might be capable of. Free of shame, she flipped herself over, lifting her ass into the air on her knees and burying her face in her bed, hands both still pawing at her needy, leaking tits. Kneeling on her front like that, her new tits hung down underneath her body, swaying and jiggling each time she moved. It made it all the more obvious just how much they'd grown. Madeline, though, was beyond being able to think about it. She just kept groping at herself, ignoring the steady stream of milk now dripping from her tits, and ignoring the way her moans were starting to change, becoming low and plaintive - and distinctly bovine.

"Mmf... mmmmf... mmmnnoo... mmmooo... moo... moo!"

***

"Madeline? You in here, babe?"

Madeline trembled in apprehension as she heard her girlfriend's approaching voice outside her bedroom. She'd called Arizona herself, asking her girlfriend to come over and help her, but that didn't stop her dreading the prospect of Arizona actually seeing her in her current state.

It had been almost a week since Arizona had given her the cow spot tattoo - or tattoos, as they had now become - and days since she had gone to work, or even left the house. She couldn't, in fact, because it had been just as long since she'd been able to wear clothes. As it had turned out, none of her transformation had been a dream, and her plight was only growing stranger and more desperate. With her body now curvier than she ever could have imagined, Madeline had little choice but to stay in her apartment, naked.

And masturbate.

Madeline hadn't been able to keep her hands off herself. Her hormones were driving her crazy. She couldn't stop herself from spending hours and hours in bed, on her hands and knees, touching herself and trying - but failing - to suppress her increasingly-embarrassing, mooing moans. The way she masturbated had changed too, becoming ever-more focused on her growing, lactating chest. No matter how hard she tried to hold herself back, she always ended up squeezing and milking her own tits until she came, leaving her slumped in her own milk-soaked mess. After one incident too many, she swore off masturbation altogether, but that hadn't lasted. After just a few hours, her tits had been swelling and aching with an urgent, insistent sense of pressure that only a good milking would relieve. And as she quickly discovered, there was no way to milk herself without ending up so turned on she forgot all about her pledge.
