There are lots of things to like about Equestria in winter. Because the humans here handle most of the weather, there's a white blanket of snow on the ground but the air isn't too terribly cold. Granted, you wouldn't want to be out on the balcony without a robe, but the air is just brisk enough to create a pleasant buzzing feeling on your cheeks. Taking a deep breath, you resist the urge to cough at the sudden chill in your lungs, and mentally kick yourself for thinking it was a good idea in the first place. It is still winter after all, even if things are temperature controlled.
 
“Hunny, aren’t you cold?” a small voice calls from behind you. Glancing over your shoulder, your eyes widen as you catch sight of Princess Celestia in a sheer red teddy that barely covers up the juncture of her thighs. And absolutely nothing else.
 
“Tia,” you laugh, crossing the space between the two of you quickly, “you’re horribly underdressed to be out here like this.”
 
The Solar Princess raises an eyebrow and then looks down at her choice of clothing. An embarrassed tinge of red mingles with her already chilly cheeks, and she’s quick to lock her hands behind her back. “Sorry, I was just wondering where you’d gotten off to.” And, with an additional pout, she quickly adds, “The bed was really, really cold.”
 
“I know, I know,” you say with a smile, ushering her back inside the palace. After you close the doors the Princess places your hands around hers, breathing gently on them in a half-hearted attempt to warm them up. Still, you decide to humor her for the time being and let her do as she will. Once her hands are suitably comfortable, she pulls them away and smiles up at you, which you respond to in kind, asking, “So, do you like your Christmas gift?”
 
“I love it!” Celestia squeals, turning on the ball of her bare foot and giving a little twirl. “It’s so light and breathable and red and sexy!” With a delighted laugh, she wobbles about for a brief moment, grabbing onto your arm for support as she lowers her leg. “Whoops, still a little wobbly. I’m just sorry I can’t always wear it!”
 
Nodding your head, you reach up and give her hand a gentle squeeze. “I know you are Tia, but the important thing is that you enjoy it while you can.”
 
The Princess pouts but gives a small nod and sighs. Her free hand leaves your arm and pulls up one of the straps as it begins to slide down her shoulder. “Yeah, but, it’s just really frustrating to have to have so many clothes. I just want to wear what I want, when I want to!”
 
You give a conciliatory hum, which is good enough for the Princess. She squeezes your hand and then hops her way back towards the bed, doing a small half twirl around one of the posts and fixing you with a smile that could light up the world. Hardly surprising, since that’s what Celestia does every day. The idea that she’s responsible for the sun rising and setting was a little hard to grasp at first, but you’ve managed to make due. The other parts of her job, not so much. Being the Princess means that Celestia has a unique link to the sun. Not in the sense that she can understand it or anything like that, but the truth isn’t much easier to swallow.
 
Celestia changes with the sun.
 
Now it’s certainly not as cut along lines such as night and day, but as the seasons move, so too does Celestia. In spring and fall, she’s a modestly busty woman who can easily enjoy academic pursuits, and in the summer she sports a larger bust that rides as high on her chest as the sun does in the sky, though she very often finds her head in the clouds. But during the winter, when the sun is largely absent, Celestia’s magic finds other ways to occupy itself.
 
“Hunny,” Celestia purrs, batting her eyes at you as she leans forward against the bedpost. It creaks under her weight, but that doesn’t stop the Princess from continuing forward until her breastbone is pressed against the wood. An enormous swath of the post has been swallowed up by a mix of red fabric, and pale breast-flesh.
 
Right; in winter, when there’s not quite as much use for her magic, Celestia begins to grow. Truthfully she packs on a few pounds all over; even her otherwise flat middle sports a healthy winter pudge. But forgetting her thick thighs and bulging butt, the largest part of the Princess, far and away, are her breasts.
 
While it would be accurate, it’s not simply adequate to call them fat; the weight and heft behind them pulls down over her chubby belly and just lets them hang down past her belly button. They spread out well past her shoulders and arms, and if magic weren’t responsible, you’d have to wonder if she could get up at all.
 
And that’s not the only thing hanging low. Like in summer, where the Princess can be a bit of a cheerful airhead, winter Celestia is just as dim, but has an entirely different understanding of fun. Namely, bedtime romps, squeezing into downright slutty lingerie, and generally doing all the naughty things she’d never be caught doing at any other time of the year.
 
“Hunny,” you hear her call again, hooking the neck of her teddy and rolling her shoulder. As the strap slides down, so does her finger, exposing ever more pale, perfect flesh, until the cloth falls away completely, revealing her absolutely massive breast. Her nipple, already as thick around as her thumb, hardens even more in the cool air. “Come back to bed.”
 
It’s really pointless for her to repeat herself a third time, so you move over, much to the delight of the Princess. She sheds the rest of the teddy, kicking it to the side and fixing you with a smile. You cast a glance toward the rumpled fabric and smirk at her, “I thought you loved your Christmas gift?”
 
“Oh I do,” Celestia purrs, batting her eyes and smiling. “I love it so much, that I want to be sure that it doesn’t get stained when I get covered in your spunk.”
 
You laugh and lean in for a kiss, which the chubby Princess gladly reciprocates. It’s not a chaste moment by any means, you have a hand kneading her rump, and she’s already got one hand pumping away at you while the other undresses you. But, for the two of you, it’s certainly the closest you’re going to get this winter.
 
After stripping you down, Celestia, with a devious twinkle in her eye, squats down and plants a wet kiss on the tip of your dick. Her tongue roams across your head soon after, and the Princess glances up at you with a smile. “Hunny,” she begins, “you know I like, love, winter, right?”
 
“Mhmm,” is the best you can manage at the moment, smiling and holding back a grunt as you cradle the back her head in your palm. That very clearly being the answer she wanted to hear, Celestia goes back to peppering you with kisses, making it about halfway down your shaft before her tongue sets to work again. She stops in a similar place, looking up once more.
 
“Do you know why?”
 
“Is it the insatiable sexual appetite?”
 
A giggle and another kiss on the head. “That’s part of it, but I really, really like what winter does to me; all of it. From my chunky thighs, to my heavy ass, my puffy pussy, my almost-baby-belly,” she pauses, taking a deep breath, and you can almost see her thighs clench together as she shudders. “My fatty, fuckable funbags, and even the stuff it does to my head. I love it all. But there’s one thing that I love most of all.”
 
Kisses and tonguing mingle this time, enveloping the whole of your dick, and even your balls. Celestia looks up at you with adoration, but still wearing that teasing, delighted smile. She pauses to take a breath, then meets your eyes again. “Most of all, I love it because I get to be your Tia. Not Princess, not Celestia, just Tia; the cockhungry girl who wants to get railed by her Hunny Bunny.” She plants another kiss on the underside of your shaft. “I love it so much that I never want winter to end.”
 
“Tia,” you sigh. Or moan. One of the two. “We’ve talked about this. We need the other seasons.”
 
“I don’t want’em,” Tia says with a girlish pout. “I just wanna be a fuckbunny for my Hunny. Don’t you want my fat titties wrapped around your dick every, single, night?”
 
Yes.
 
“Of course I do, but it’s not about you or me, Tia. You know that.” She pouts. She knows. You pat her cheek lightly and give her a smile, adding, “So we better make the best of the time we’ve got, huh?”
 
That gets a smile out of her. Rocking onto her knees, Celestia engulfs your shaft in between her breasts, causing it to disappear completely. Even still, you can feel the warm, heavy pressure of her tits surrounding you as she begins to rock forward and back. Her eyes shine, the disappointed girl gone as she begins to give you small murmurs of encouragement.
 
“You’re right, Hunny; I need to milk these moments for all they’re worth. And that means milking you too!”
 
The spit-soaked shaft slides easily through the space between her breasts, Celestia glancing between her cleavage and your face, her smile never ceasing. Up and down, back and forth, the Princessly pillows provide plenty of pressure. It really won’t be too long until she gets exactly what she wants.
 
“Hunny,” she says with a familiar purr, “shoot a big one for me, okay? See if you can get it onto my face tonight.”
 
“Dirty girl,” you chuckle, which earns a delighted giggle from the noble knob nibbler. Soon after you feel your body tighten and you thrust your hips up into her breasts. An excited smile crosses Celestia’s face, the Princess closing her eyes and opening her mouth when the first shot comes, landing with a squelch as it pings her cheek. She manages to get the second into her mouth, while the third and fourth only make it as high as her chest and not even out of her cleavage respectively. Of course, Celestia doesn’t mind that in the least, wiping her cheek clean with a few fingers, suckling on them as she uses her other hand to massage the splattered spunk into her tits.
 
“Mm,” she squeals, finally freeing her finger from her lips and moving on to covering her chest in the creamy offering. “Hunny, that was a great job. It tastes just like Christmas!”
 
You give a small, breathless laugh, continuing to cradle the back of her head as she happily massages the splooge into her skin. As she’s finishing up, you clear your throat and flash her a smile. “Tia, have I ever told you about a special holiday called Groundhog’s Day?”
 
The Princess’ eyes widen and she shakes her head.
 
Oh, this could be fun…
