The sisters grinned as one. Yup, they were Naruto's sisters all right. Tsunade groaned and rubbed her forehead. It was way too early for this. Screw it, they were just The Twins to her now. Thing One and Thing Two.
"Is your mother upstairs?" Tsunade changed the subject.
The twins both nodded. "Yup, she's in the loft. It's the only room with any privacy." One of them said.
They led Tsunade into their home. Full of tasteful luxuries long neglected. A weird smell struck her. Not sweat from the twins, something else. …Fishy? Maybe. Probably perverse. She couldn't quite place it. There was a door under the stairs, the basement most likely. Dark-painted and thick and doubly locked. How sinister, Tsunade didn't ask what was down there. Every ninja family had secrets.
She tried not to watch Nori and Naruko's hips wiggle as they climbed the stairs. The spandex shorts did not help.
As they had said. The upstairs had only one open room. A small landing circled the stairs. But only one door of the nine lay open. The rest were locked. Nobody knew where Kushina kept the keys. Or what was even in there. Old memories, probably.
Naruto and his sisters shared the open room. While their mother camped out on the couch. But they had switched roles. They'd agreed to donate their private space for the cause.
Tsunade left the twins outside. She ventured in alone. It was hard to see, the ceiling lights had been broken for years. No electrician wanted to work in the 'demon house'. The only window was a tiny glass circle on the opposite wall. The bed though was new and big, enough for three people to sleep on in comfort. A gift from Hinata's family no doubt. An immense, curvaceous form hibernated on it. Beached and swollen.
Tsunade stepped inside and shut the door behind her. She crept to the bed and flicked on the nightstand's lamp—
Her jaw dropped.
Kushina lay naked atop the blankets. And honestly, Tsunade doubted she could have fit under them. She wasn't just pregnant, she was Pregnant. With a capital P. Sloshy breasts half again as big as her head smothered everything between her belly and her shoulders. And oh, what a belly it was. The sort of stomach preggophiles would scour the internet's seedy fetish forums for dirty pictures of.
Tsunade struggled to comprehend her immense dome of a stomach. How far along was she? How many babies were there? Not a singleton for sure, not unless a horse had bred her. Twins at least, probably triplets. Questions buzzed inside her head as she watched that massive stomach expand and contract. Driven by slow and heavy breaths from its host.
Kushina's stomach was pale and heavily oiled. A valiant struggle against the dreaded stretch marks. It glistened in the lamplight. A dark line clove it down the middle, her linea negra. An accent to encircle her round and popped-out belly button.
But even stranger was her face. No signs of age at all. No crow's feet, no smile lines, no blemishes of age. Zip, zero, nada, goose eggs. Either Kushina had discovered some kind of magic spa. Or she was changing just like Hinata. Tsunade took a deep breath and shook her patient awake.
"Kushina?" She said.
"Mmm… Five more minutes…"
"Kushina?" She tried again.
"Noooo… Oh honey I don't can't go again. Mama's not as young as she used to be…"
Tsunade grumbled and cleared her throat. "Ahem!"
Kushina cracked one eye open. "Hmm? You're not Naruto." She rubbed the sleep from her eyes. "Wow, I was out. How long was I asleep for?"
Tsunade said she didn't know. She'd only just gotten here.
"Huh, well let's hope I haven't lost track of the days yet. Let me guess, you're here for a check-up."
Tsunade nodded and helped her patient roll over. But even that was a trial. Kushina grunted and strained under her mammoth midsection. Pinned and helpless beneath it. Tsunade needed both hands and a touch of chakra strength to balance Kushina on her back. All while images of beached whales glided through her mind's eye.
Even after she'd righted Kushina, the trials did not stop. Kushina's cream-stuffed tits almost smothered her. Flopped over and covered half her face. She needed her arms to hold them back.
Tsunade cleared her throat. "…Right, so let's start with the obvious. Do you know who the father is?"
"No idea." Kushina shook her head.
"How can you not know? You were there for it weren't you?"
"Eh, maybe? The last few weeks have been a blur." Kushina said.
"Months you mean." Tsunade corrected.
"Uh, right! Sure. That's what I meant."
This was a conundrum and a half. Their family's high status was precarious at best. Sure, Naruto was the greatest hero of his generation. But fame was fickle. And if it got out that his mother liked to sleep around...
Well, let's just say their graffiti collection would start growing all over again.
Tsunade decided to nip the problem in the bud. She loathed doing paternity tests. The last thing she wanted was to play Jerry Springer to unhappy couples. But here and now, she could make an exception. Tsunade sheathed her hands in green chakra and pressed them to Kushina's drum-taut belly.
When the results came back, Tsunade's own stomach dropped.
"I don't like that look. My babies aren't sick are they?" Kushina's grip on her wrist clamped hard.
"No no, the kids are perfectly healthy…" Tsunade reassured her. "…A little too healthy."
Brow furrowed; she gave the unnaturally young MILF all the proper comfort while she ran the test a second time… Then a third… And a fourth… The result was identical no matter how she tried. Her stomach hit rock bottom and turned over. That couldn't be right, could it? Naruto would never—would he? With his own mother?
Tsunade's fingers tensed. She gripped Kushina's large belly harder than she meant to. The owner of that shiny stomach gripped her bedsheets and hissed. It wasn't a pained sound.
"Tell me this test is wrong, Kushina." Tsunade couldn't look at her.
"What does it say?" Kushina asked with her eyes scrunched closed.
"You know what it says."
Kushina fell silent. Flushed as stimulation filled her face with tingles. Migratory little happy buzzes born and bred in her gravid midsection.
"I've been so lonely, Tsunade."
"Lonely?! That's your excuse?!"
For some reason that struck a nerve. Tsunade stormed to her feet and towered over her patient. Fists on her hips, she stuck a finger in the younger woman's face. Kushina didn't seem bothered at all. Drugged into submission by dopamine and pregnancy hormones. Her head was off to mars.
"This is sick! It's wrong! Hell forget that it's fucking illegal!" Tsunade backed off to let her temper cool. "Do you have any idea what incest does to a child? Any idea?"
"But you said they were healthy." Kushina moaned. A protective hand rubbed the sore spots Tsunade had left behind.
"They can't be. Their father is your fucking son it doesn't make any sense."
Tsunade paced back and forth at the foot of the bed. Kushina's glistening and baby-stuffed stomach was so huge that she couldn't even see her face from this angle. Just a disembodied womb with arms and legs. She peppered the veteran mother with questions.
"Who put you up to this, Kushina? Orochimaru? This has his handiwork all over it. What about those ROOT splinter factions? I knew we should have locked them all up the second Danzo got his just desserts…"
On and on she went while her patient slipped in and out of narcotic preggo bliss. Only occasionally coherent enough to answer questions. She denied every wild theory Tsunade floated with bubbly giggles. Until she grew bored and let the truth fly.
"Nobody did I-- I watched them do it. By accident! …At first. I knew it was wrong but I couldn't help myself. Then one night Hinata caught me peeping through the keyhole and." She let out a long and throaty whine. "She invited me in. And when my son shoved his massive ugly dick inside me. Oh my god he's so much bigger than his father. I havn't had a decent orgasm in years."
Tsunade stopped short as Kushina rambled on and on. She spun description after vivid description of her only son's ridiculous sexual prowess. She made comparisons to livestock and water fountains. How the pungent stench of his semen belied a flavor that was savory beyond savory. Tsunade felt her own blush rise while heat blossomed in her chest. She'd heard snippets of from Hinata but this? She tried to bring her patient back to earth.
"Okay okay. I get the picture. Tell me where Hinata is right now."
Kushina cracked one eye open. She rummaged through cotton candy memories. "The basement. That's where Naruto goes at the end of every day. The drain down there's the only one he can't clog now."
Tsunade sure didn't need that bit of info. But a lead was a lead. But before she could leave…
"Girls!" Kushina called into the hallway.
"Hi mom!" The twins appeared out of nowhere. Their fit and busty frames blocked the door.
Tsunade jumped. Where the heck did they come from? Not even ANBU could hide that well.
"Can you two do mama a favor and show Lady Tsunade the basement? She wants to see Hinata."
Both twins lit up. "You're gonna to be one of us?"
"Please tell us you are. He gets so needy now." The other locked Tsunade's arm between her large breasts.
"Girls." Kushina calmed her brood with a raised hand. "Let's not get ahead of ourselves."
The twins sighed in perfect sync. "Sorry, mom."
Tsunade did her best not to be creeped out. But god damn did those two belong in a Kubrick film. Not that they would have made the cut with their DD tits and child-bearing hips. One look at these two made it pretty damn clear where their brother got the inspiration for his sexy jutsu.
The twins led Tsunade through their home. Now she placed the weird smell from before. Semen, thick and heavy in the air. With normal men the scent was subtle. But here it hung heavier than incense. They led her to the door under the stairs. Both girls had a key. One for each padlock. A few skillful twists popped the locks. And together they pulled the heavy oak slab open.
Now the grunts came in earnest. Half-man half-beast and all rut. Claw marks stood out stark on the door's inner face. One of the sisters pulled the chain. And a bare lightbulb lit the landing above the lonely stairs. Stairs that crawled down into the dark.
Wet schlick schlick schlicks wafted on the breeze. Lubed flesh ground on lubed flesh. Tsunade steeled herself for the journey down. Fists clenched solid; chakra flowed into them. Ready to be blasted into the enemy. She took the lead down. Old pride demanded that she not let her fellow blondes control the situation.
It was dark in the basement. Skeletons of dusty storage shelves loomed huge in the shadows. But the tiles underfoot felt new. Fresh grout barely smellable over the man-pheromones. Tsunade hesitated the tiniest bit. There was too much chakra in the air to sense through.
But the sounds? The huffs and snarls and fleshy plap plap plaps of flesh smacking flesh? Those noises came louder than ever. Something strong shifted in the dark. A mighty limb restrained by a steel chain pulled tight.
