"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.
