Side Effects!

Tsunade should have put her foot down. But she couldn't bring herself to. She shoved Hinata onto the bed and climbed on top. Hinata stopped her before she shucked her coat and top.

"This isn't for you. This is for me."

Tsunade dove into Hinata's distended breasts. Doughy flesh devoured her fingers. She couldn't force the left nipple past her lips. Until Hinata pinched its puffy areola between two digits and stuffed her thumb-tip milk bud inside.

They lost themselves in each other. Vanilla-sweet cream splashed on Tsunade's tongue. And yet more milk came when she sucked. Spouted a water fountain's gentle pressure. She let this woman half her age breastfeed her. All while her master-medic hands found duct after engorged duct of un-expressed mother honey. Hinata raked her new, sharp nails on her back. Pale purple daggers to shred her white coat. An edge of pain in all that homey bliss. Tsunade watched how the cocky grin never left Hinata's perfect lips. No matter how flushed and sweaty she became. Lovely face haloed by her gem-lustrous hair.

When they finally disengaged, Hinata basked while Tsunade staggered to safety. Away from the newborn succubus. Whose quite literally basketball-sized breasts rose and fell on her powerful chest. Glazed with sweat and milk rivulets. Nipples ringed with kiss marks courtesy of Tsunade's pink lipstick.

The sixth month proved the lewdest yet. Tsunade fought back her sapphic lips as best she could. Until Hinata's glorified bra of a mesh top flew off. And her resistance crumbled beneath the marshmallow-y mass of her meaty zeppelins. She'd gotten piercings, six of them. One silver barbell through each nipple (to control her milk flow). An amethyst venom piercing (two tongue studs close together, for blowjobs). A little charm of a lion's head to adorn her navel. And lewdest of all, a real-life diamond clitoris stud. The sort of genital jewelry veteran pornstars sprung for.

Tsunade had never seen Hinata's bottomless before. So she didn't know when the girl had waxed her mons smooth everywhere (save for a tasteful strip above her slit). But it made her look so tasty. That was the day she learned the taste of future mistress' cunt.

Blueberries!

And the measurements for this month? She forgot to measure those glorious breasts. But she'd estimated her patient's height at least. She was getting huge; Tsunade only came up to her nose now.

The seventh appointment discarded all pretenses. Tsunade made sure to get herself well and truly plastered beforehand. Her pride could never have endured this sober.

Hinata bit and groped her as they writhed together. Naked on the cold tile floor. Toned legs scissored as made-up lip kissed drunken sloppy and nipples fenced for dominance. In terms of sheer size and power, Hinata's bust had her famous pair beaten. But oh did Tsunade and her girls put up one hell of a fight. She wone exactly once, when she forced Hinata's nipples to invert. Pushed by her own stiff glasscutters.

As Tsunade stirred her large nips inside Hinata's puffy, inverted areolae, she wondered if this was how men experienced sex. The power of penetration, of control and dominance. No wonder they were such perverts. This felt good. But the sheer size and force of her lover cut her victory short. In a flash, Hinata rolled them both over. Slipped her nipples free of Tsunade's and plopped her enormous tits square onto her rival's face.

There were worse ways to suffocate.

Hinata finished first. Sensuous and cocky but untempered by age. Her breasts squirted right along with her cunt. Tsunade licked her clean while she humped her glistening mons. It was only after she herself succumbed to the little death, that she remembered her duty as a medical ninja.

The tape measure came out, and the cold numbers almost made Tsunade cum a second time. She read them off as her hips ground on Hinata's firm thigh. 149 centimeters. 58 inches of pale perfect breast meat. Hinata had blasted past the end of the alphabet. Even a Z-cup would struggle to contain those titans.

She'd gotten even taller, again. Tsunade straightened her legs to get the full measure. The numbers made her jaw drop. Six feet tall?! Seventy-two inches on the dot. How much was that per week? Per hour? She was to cum-brained to figure it out.

It was as if her body refused to submit to her inflating chest. Even now at their ridiculous proportions, the rest of her grew with those ivory mountains. Even now at their mind-blowing size, her breasts still only reached to the bottom of her ribcage.

As they lay together on the floor. Twined together while Hinata's gigantic bust filled all the space between them, Tsunade tried to find her shame. But it was long gone.

Upon the exact day of the eighth month, Tsunade heard her patient strut down the hall before she saw her. Gasps echoed outside. Followed by envious whispers and audible whumps as male doctors walked boner-first into walls. Hinata's breasts entered the exam room a full half second before she did. And the rest of her had to duck under the lintel.

"Oh my god, what a bunch of pervs." Hinata groused and threw up her arms. The simple gesture made her massive bust bounce. Meaty audible on her bare stomach; plap plap!

Tsunade choked on her sake. It hit harder than a brick to the forehead. Hinata's girls were gigantic. The sort of overblown gag-boobs you'd expect in a comedy anime. Or a hentai.

And her height. Good god almighty she was huge. And those platform sandals made her look even taller still. Tsunade couldn't imagine where she'd gotten wicker footware rated for such a sheer mass of woman. The heels made it tough to judge but she had to be, what? Six foot four? Like Naruto's sisters? Those heels made her look even bigger.

She took a deep breath. "Well let's start with the measurement, shall we?" Tsunade rummaged for her tape measure.

Hinata popped her lollipop from her lips. A shiny strand connected them to the grape candy. "Don't bother. I did it yesterday."

Tsunade blinked. Since when was this "new and improved" Hinata so proactive? She should have smelled a rat. But those swollen milky bosoms filled her head.

"I've got 68-inch tits now, granny. And I've still got them under control."

…That was strongly debatable. Tsunade's head fell into her hands. It embarrassed her, how out of depth she was. "Don't call me granny."

Hinata laughed and ignored her. "Naruto fucked me hard all through the weekend, you know. Forty-eight hours of nonstop raw dogging. You know what he did when he wore himself out? He slept on me like a bed. These milky fuckers make great pillows."

"I don't need to know that Hinata."

Hinata's smile turned to sugary poison. She sashayed to the much older woman. Until her tits drowned Tsunade's. Gigantic breasts bounced with every step. So close that her forward evet horizons docked pudding-soft with Konoha's former #1 bust. She smelled delicious, lavender and sweet sweat. Meaty zeppelins filled Tsunade's vision. Hinata towered over her. So much so that her boobs were square-level with the older woman's face.

"Aw what? Jealous? Wanna join in? You look a little… stiff."

Stiff? Tsunade noticed the state of her nipples. Traitorous as ever and diamond hard. She seized her coat and slammed it shut tight.

"Heh, nice glass-cutters."

"Have…" Tsunade thanked god she didn't wear glasses. She would have fogged them up. "Have there been any other side effects?"

"Nope! Not a one. I think my girls've finally calmed down. Naruto's been a big help by the way. With the milk and the new bras and everything else. You know I have to custom order them now?"

Tsunade said she hadn't. And wished she didn't sound so… transfixed. So curious to see this final form of her bust. Naked on her table and eager to be milked.

"Well anyway. That's all I wanted to say. Looks like I won't need your help anymore."

I won't need your help anymore. Tsunade turned the awful phrase over in her head. It hurt more than she wanted to admit.

Hinata strutted back to the door. Even here in private, she worked it like an escort on parade. All while Tsunade wrestled with feelings that had not blossomed in years. Not since Dan or Jiraiya. And never with a woman. The object of her obsession flung one last curveball.

"By the way, Kushina's pregnant."

That got Tsunade's attention.

"She moved on?" Tsunade asked.

Minato had died the day of Obito's attack. And Kushina had been left to raise their only son (plus his slightly older twin sisters) alone. In the midst of a village that hated them. Life became hard and Kushina had struggled with it. Her status as the so-called demon mother had disqualified her from the dating scene. Which was hard enough for a woman her age.

Even now, with her son the hero of the ninja world. Things were still tough. Now all the men who'd degraded her wanted to climb into her bed. But Kushina was too smart for that. She'd turned the act of suitor rejection into an art form. Until now, apparently.

Hinata shrugged. "I dunno. She hasn't said who the father is. Still, you'll want to come around and look at her."

Hinata left before Tsunade could answer.

==0==

She could have said no. Should have said no. Exerted some control over this madness. But Tsunade's life was out of her hands. She rang the doorbell on the old townhouse. The Uzumaki's lived in a nice part of town. And their own house had been equally nice… once. But the village had not been kind to it. Or them. Every window and square inch of stucco had fallen into disrepair. While years of built-up graffiti made it look that much worse.

Life had turned around of course. Naruto was a hero now, not a pariah. His status had trickled over to his mother and sisters. Nobody dared add to the collage of 'Freaks!' and 'Devil Family!' anymore. They could have fixed it up, of course. But with the rampant insanity of the last few years, well, it hadn't happened yet.

But it wasn't the family's dreaded matriarch who answered. Nor was it Naruto or Hinata.

"Wow, holy shit. What's up, Lady Tsunade?" Naruko filled the half-open door with acres of bare and tanned skin.

Tsunade gulped. Dammit! Did she just like women now? Stupid Hinata and her stupid lesbo-boobs. "Just Tsunade. I don't work for a living anymore."

Naruko looked down on Tsunade. It wasn't a snob thing; it was a height thing. Naruko had quite literally a foot of height on her. The girl was tall, enough to match Hinata's Valkyrie-esque stature. Thick hips and heavy, golden-tan breasts strained her black spandex clothes. Workout gear by the looks of it. Naruko had to be the only woman Tsunade knew with honest-to-god six-pack abs. Well, almost the only one.

"Hey, Nori! I think we're important now! The hospital sent a sannin!" Naruko shouted across the house.

"Orochimaru!?" An identical voice called back.

"Nope! The other one!"

"…Jiraiya?"

Tsunade and Naruko both facepalmed. And then on queue, here came the other Konoha citizen with a midsection like a nordic goddess. Nori Uzumaki, Naruko's identical twin sister.

"Heya, Lady Tsunade." Nori materialized next to her sister. Hoo boy now there was two of them. Unsexy thoughts, Tsunade. Think unsexy thoughts. Roadkill. Politics. Sports! Anything!

…Crap. It didn't work. Well at least these two hadn't changed at all. On the outside at least.

"Uh, good morning girls." She cleared her throat. "Nori, Naruko." She nodded to them each in turn.

"I'm Nori." The first twin pouted.

"Yeah! And I'm Naruko." The second added.

Tsunade blinked. "But you said…"
