Thinking about the Boring Billion. From 1.8 to 0.8 billion years ago, not much changed about life on Earth, nor even about the abiotic conditions of Earth itself. Earth, it seemed, had entered stasis. She was a planet almost three billion years old, her fiery Hadean childhood long behind her. The Archaean eon had brought water and life, had made her unique among her siblings. The young Earth had evolved many different kinds of prokaryotes, doing all sorts of fascinating things, making and using sulphur, methane, carbon dioxide, and eventually oxygen. Her atmosphere transformed, her skies turned blue, her oceanic iron settled into minerals, and life evolved symbiosis to grow into new, larger eukaryotic forms perfectly adapted to the oxygen. There were even some brief, quickly abandoned experiments with multicellularity. Earth was a bright young planet full of promise.
And then... nothing. As poised as the Earth seemed for her next big thing, it just didn’t come. She kept on spinning around the Sun as she always had, and her life, as chemically intricate and beautiful as it was in its own way, kept on doing largely the same things. What developments there were seemed slow, small, perhaps taking far longer than they needed to. And as the long ages of the Proterozoic stretched into a billion years, life on Earth, it seemed, was all it ever would be. Blue skies, blue seas with fascinating little unicellular creatures under their surface, and rocky continents dancing their slow tectonic dance. It wasn’t a bad existence, to be sure, and it must’ve been difficult to imagine it ever changing. After all, over a quarter of the planet’s existence had been like this. Earth’s future looked to be a few more billion years of it before her eventual fiery end.
But long before the Sun’s fire came for her, it was ice that finally broke the Earth. As she neared her fourth billion, the worst ice age Earth ever experienced came over her. Whether because of an unfortunate configuration of continents, a big shift in atmospheric gases, a lack of volcanism, a fluctuation in the Sun, a shift in her orbit, or some combination of these, the Cryogenian period brought glaciers all the way down to the equator. Earth, so full of life and wonder once upon a time, now looked like distant frozen Europa as the worst crisis since the Late Heavy Bombardment turned the planet into a glacial grave. And just when the ice retreated, when it seemed like things were looking up - the planet immediately froze over a second time.
But her life was tenacious and somehow clung on, in the liquid oceans below the ice and in the rare open seas around the equator. And when the ice thawed a second time and warmth returned, Earth did not return to her old stasis. When her life retook the formerly frozen wastes, it developed new tricks, new forms, spurred on by an atmosphere now more oxygenated than ever before. Multicellular life, mere experimental playthings in the past, became Earth’s hallmark and soon filled her seas with animals, plants, and fungi. Fronds bloomed on the sea floor and gelatinous blobby creatures wandered in between them and they were like nothing that had ever appeared before. The Earth bloomed with this new life for a time.
But it turned out she didn’t get it quite right, ran into a dead end, and the Ediacaran garden withered as suddenly as it had bloomed. But from its remnants, a second attempt at animal life came, very different than before yet building on its successes and failures. And this time, it seems, everything just clicked. From so simple a beginning, endless forms most beautiful and most wonderful evolved, every one of them begetting a hundred new possibilities, starting a runaway chain of creatures that would soon turn the bare continents green and even soar in the skies. After four billion years, the Earth finally reached the beautiful and unique potential that had been so unimaginable during those billion years that lie so far in the past and are so easily forgotten now.

Muzan’s eyebrow twitched as he heard you drop, yet another book from his bookcase driving him out of his concentration once more. How could he focus on his task if you kept making noise?
Not even a millisecond later, another thud made Muzan squeeze the graduated cylinder he was holding, causing tiny pieces of glass to fly over his desk area. You let out a slight squeak as the man appeared behind you, yanking harshly at your tail causing you to fall from the ladder onto the hard wooden floor. Looking up sheepishly, you were met with a pair of piercing red eyes staring completely through your head.
“I’m sorry master! It was just that the book’s where so heavy and I couldn’t catch them before they hit the floor.” you brought your knees up to your chest as your tail wagged like a snake along the floor.
“Why do I even keep you around, if you can’t do anything right?” he spoke in a low voice, if it was possible you would shrink yourself even more than you already were. You didn’t say anything back, causing the man’s eye to twitch even more. Nothing outside of the regular things upset Muzan more than you. It’s like he had a special nerve that only you can hit.
You felt a tight grip around your wrist that pulled you quickly to your feet, dragging you along the dark black hallway leading to an area you were oh-so-familiar with. It was his bedroom. No one was allowed into Muzan’s bedroom unless he brought you there. You were brought out of your thought as muzan tossed you onto the floor, as he made his way to a solo chair in the room removing his belt in the process. He sat on the chair shaking his head slightly in disappointment.
“Crawl over here,” he spoke, as you got on all fours crawling to him slowly and steadily before stopping right in front of him.
“Lay across my legs,” he commanded once more. Making way, you laid your body long on his legs which were quite uncomfortable for your stomach and boobs.
Muzan ran his right hand along the material of the dress you were wearing, it’s not like it was covering much anyway. He stopped right where the tight material ended, pulling it up and bringing your ass into full view. He kneads the plushness of your bottom, completely naked already. He commanded you not to wear panties anymore once the relationship got intimate.
“Now, why should I not strike you with this belt?” he asked tightening his grip around the black leather belt.
“Master, I apologized for dropping the books al-” a very hard smack was brought onto your bottom causing you to let out a yelp.
“Wrong answer” he sighed as your bottom turned red like an apple, if you were human you would’ve been done for.
“I’ll give you one more chance.” he tapped his foot slightly looking down at you.
“I did everything you asked me to do-” You were cut off once again as the leather made contact with your bottom once more.
“Why do we have to go through this over and over again?” strike
“If I give you a task I want it done flawlessly” strike
“You dropped 5 books today, that’s 5 too many” strike
“Just pitiful” strike
By now, your face was flushed just as red as your bottom. He stood up, causing you to fall on your bruising bottom. He pulled you up by your forearm, and brought you over to his bed, pushing you down on your bottom once more causing you to hiss out in pain.
He brought his face down to yours, staring deeply into your eyes. “What kind of succubus are you? you’re weak. weak physically and mentally. how does one who does the dominating become the submissive? What a waste of a demon, you should’ve been born human.” Muzan’s words were mean, you were always sensitive and did he know how to hurt your feelings.
He sighed, adjusting his clothing and loosening the tie he was wearing. He removed his bottoms, running his fingers through his hair. “Luckily I found you, someone could have really taken advantage of you.” he moved your legs to each side of his body, hardened length making way to your dripping entrance.
Your back arched off of the bed as he pushed himself fully into your tight cunt, squeezing him with each muscle of your body. Without warning, he began pumping in and out of you causing the room the be filled with a slight squelching sound.
“Master, you’re so deep” you whined as you pulled at the zipper of your dress splitting it down the middle and allowing your breast to bounce free. Although he’s never admitted it, it did turn him on watching you toy with yourself. Taking two fingers into your mouth, you coated them in your saliva pulling them from your mouth with a pop. You used the moistened fingers to rub circles on your clit, your other hand tugging at your nipples causing you to let out a sultry moan.
“Fuck.” you heard your master say before you felt his warmth leave your body. That was only momentarily, as he flipped you around grabbing a fist full of your hair in the process. He stretched your neck back, muttering “open” as you stuck your tongue out happily allowing your master to dribble his saliva into your mouth. “swallow” you happily obliged.
He gripped your hips harshly, pricking through the skin as crimson droplets slid down your hip. He leaned over you, his chest to your back allowing him to deepen his thrust, the entire length puncturing your walls.
“Master I’m gonna cum” you whined clawing at the bed sheets, chasing your high as a tingling sensation made its way through your body. Muzan let out a deep sigh as he rutted into you one final time, before allowing his seed to take over your insides. Just as your high was about to overcome, you felt muzan remove himself from you.
“Master...I didn’t get to cum” Your eyebrows furrowed with desperation.
“And who’s fault is that?” he asked straightening out his attire that he had quickly put back on.
“Now when I come back, this room better be spotless. If you can do that, I might just reward you.” He walked out of the room leaving you in the dark and completely frustrated.
