As soon as they were freed from the encasing shell, the subterranean cities were freed from terra firma, too. Built amid coral-pink rock formations and caverns, the earliest settlements had been subjected to devastating cave-ins and tectonic plate shifts; so they rebuilt stronger, sturdier, able to weather the strongest shaking. That meant that, even if Natsuki wasn't as precise with the knife as its owner, the settlements remained in one piece as she sliced through them; carried them out of the handheld stratosphere; and dropped them down.

"Whoop-! Why can't you ever stay still?" Her peachy eyebrows lowered, not even bothering to catch the settlement while it fell through the air. The landmass passed their opposing, bare legs, watching the shifting knees become distant memories; and finally landed on Yuri's slender, outstretched foot, bobbing amidst the sweaty pores.

The long-haired maiden's reflexive groan was louder than warranted; so much so, that her eyes darted back and forth to make sure nobody heard her. Nobody, except for the minuscule settlements sharing the friends' secret. "I... I still can't get over it. The feeling of... so many of them..." To calm down, she rubbed around Natsuki's stomach, as if caressing a teddy bear; brushing in circles around the country within. "I don't want... any of them wasted..."

"Geez, Yuri, don't get so dramatic!" She stood up, holding another hand still to balance the next settlement she was slicing. People already barely clinging to her from perspiration struggled to keep a hold on the shifting masses of peachy bare flesh. A seemingly-endless, silvery blade that parted all in its path, splitting asunder mountains and seas. "I can't stand it if small things like that boss you around!" Finally getting a little bit of land separated and past the barrier's remains, she carried the newly-made island a short distance; to put it on the dainty hand before her. The tiny bit of soil and rock was like nail art.

Blinking down at it, she nodded politely with a steadily-growing smile. "I... I understand..." In approval, Yuri also stood to her full height, and ran that palm on her friend's scalp; a storm of short, pink hair falling upon the people, generating humid jungles. "I'll only let one small person boss me around... Planet Natsuki~"

Lip quivering, her celestial body struggling to stay in place as it grew flushed from their shared warmth, the pink-haired poet prodigy began slicing and dicing into the layers of the world with increased vitriol. "D-don't tease me like that! You're supposed to be teaching me, about this right? Then how come you have so few of them on you? Here - " the carved-out kingdom practically flew out of the marble's gravitational pull from her force "- I'm sure these guys will love it in Yuri's smelly armpit!"

With the world placed in the meaty mass, minute hair stems and heated fog rising around them, the lavender lady reached her arms up to watch them; and rubbed her hair. "Ufufu, then please lie back and let me show you... How wonderful it feels to have this piece of land behind your ear~"

With multiple nations stuck in the small space, Natsuki quickly took the world back, and began excavating more and more of their buried treasures all at once; only to make them new decorations on her lover's body. "Welcome to Yuri's big boobies, losers! You better put your best into showing your new world the respect it deserves!"

She breathed in, quivering, struggling to keep focus on the shrinking sphere between them. "Please, Natsuki, please... you're not going to take these two islands away from me, will you? They'll look absolutely perfect... on either of your soft, squeezable thighs~"

"No fair! Then I'm gonna move these continents to your round ass cheeks! I'm sure they'll have plenty of room to spread out there!"

"Aaaaw, but I can't see them there... not the way I can see them when they're on your panties..."

"Hey! Just for that, I'll put this spot around the nape of your neck!"

"Then I shall do... this~"

"Just try it, I'm gonna-!"

By the end of their teasing session, the two women were rolling around atop each other, barely-clothed, both panting. The pink planet's resources had been stripped to smaller than a bead's size. Its core was melting in pooling humidity, perspiration, and drool, survivors struggling to build dams to block it up. The rest of them were shaken with the quick, exhilarated gasps from Natsuki's thin lips; which joined with the measured, cool gulps from Yuri's deep lungs.

Mystified with the lovely expression her friend made, Yuri reached a shaking hand towards her face. "Absolutely entrancing..."

"Surprise attack! Nyum!" With a quick lunge, the fangs of Natsuki swept over the city upon that perfume-scented hand; swallowing it all in gushing juice with a fast, but passionate, kiss. When the hand pulled back, nothing remained; everything sucked down the undulating caverns of her mouth.

"N-Natsuki! Your tongue--! It's... it took it all!" She gazed at the wet mark, looking almost ready to swallow it herself.

Rubbing her stomach, her partner nodded. "Mm-hm! They're sweet! And sugary! And they mix well with the deep taste of your skin oils..." Giving further kisses down the hand, the immense suction took in thousands the population as sustenance - though it seemed secondary to just covering the other girl in smooches. "I wanna have a Yuri Nyotaimori!"

With her backhand still held out, the woman squirmed as it approached her arm. "H-how did... that old Austrian poem go, again?... A kiss... on the hand... is for respect..."

"And on the open forehead..." She paused to part Yuri's bangs, revealing a small settlement beneath. "...is for friendship!" A longer, deeper kiss left a red mark where people used to be, right in a spot that Natsuki would never be able to reach if they weren't sprawled on the floor.

Yuri's mouth lowered to Natsuki's blushing face. "On the cheek..." She brought her lips down, the frenzied suction lapping up more of the resting world; a pink monstrosity that none of the minuscule inhabitants could avoid, especially having just been relocated.

"For a kind greeting! And your lips... Those lips..." They shared another oral kiss, both massive mouths meeting to wrestle with the populations inside, tangling them amid vast mountain chains of molars and incisors.

When they'd finished, Yuri panted. "That's for love. Now, the eyelids, for l-longing, or languor..." The hungry kisses became gentle, dew spreading across Natsuki's shut, swaying lashes.

Taking her hand again, the shorter girl's heart rose, blossoming out. "Palm is for desire..." She kept kissing up, a long suction that slurped millions in a single mouthful; and with room still remaining for other parts of the amazing meal. "...So are the the arms, and- and-"

"And the neck..." Both of their shoulders stroked together, bathed in a blissful warmth that baked everyone witnessing. "Anywhere else is... kissing anywhere else... is an act of madness..."

With her eyes darting open again, the smaller colossus tilted her head. "Eh? That sounds wrong. The translation I read said, 'kiss everywhere else with frenzy'!"

"I guess... even if not everything comes across the same way... I'm okay with some madness... if I can share it with my beloved..."

"Madness? I don't like it when people call it that... But I guess I have to be a little out there, since I fell in love with someone like you!"

Basking in what seemed like everlasting sunlight in that room, more and more of the shattered planet met their end in one mouth or another. Their shared breaths spread across the sweet-tasting realms, caressing one another's bodies and spirits in deep, hypnotic warmth. What was a series of unstoppable apocalyptic events up close was two girls sharing a passionate moment. Across Yuri's waist, Natsuki's face, her soles, her bosom, two pair of cheeks, one pair of hands, one pair of lovers, the entirety of the map was rearranged and replaced with kiss marks. It continued long after the only remains of the pink planet were swimming in stomach acids. All previous history culminated in these two open, revealed bodies, hugging one another closely.

But wait, what about that purple planet?
