"There are more things in Heaven and Earth, Tenryuu, then are dreamt of in your philosophy."

When Tenryuu first heard the Admiral say that quote she thought he was merely being flippant, or making an odd joke about her name. It turned out to be a quote from a play, meant to imply that human knowledge was limited, and that there's still things outside of what people understand. Which, sure, that summed up the Japanese Naval Special Operations Bureau, but how much else could there even be?

Well, "Sword Tomboy Island" for starters.

It sounded like the sort of prank Tatsuta would pull on her, but the flyer was entirely too well-made and Tatsuta seemed just as surprised at it as Tenryuu. There was the possibility that it was a trick of some other, better-connected individual with a grasp of graphic design and too much free time, but far from leading her to an empty building or an annoyed private resident, the directions took her to a small ferry, the crew of which simply waved her on board with no hesitation. The greatest trick of all, of course, was that Sword Tomboy Island was real and developed to a level that would rival most resort towns.

"I didn't think there'd be so many people here," Tenryuu confessed to Mordred, walking along the boardwalk.

"That struck me as well," Mordred replied. "To think I was so archetypal." Not including other Servant classes and holiday variants, she mentally added.

"Yeah, really. There's one thing I don't get, though."

"What's that? Who paid for all this?" She gestured to her surroundings and between them, indicating their bikini-and-jacket outfits; red and purple for Mordred, and white and her fur-collared one for Tenryuu.

"Nah, not that. What I wanna know is, why do we all have dicks?"

"Oh." Mordred glanced down at her package, neatly supported and ensconced in her bikini bottoms. "I'm certain my father had one at some point, so mayhaps it's genetic?"

"I'm a boat."

Mordred gave a helpless shake of her head. "Then I have no answers."

Tenryuu lapsed into thought for a second before snapping her fingers. "What if it's symbolic? I lost track of my sword at around the time I noticed I had this."

"Yes... yes. I haven't been able to summon Clarent, so perhaps."

"So was Clarent a short sword?"

"No, it was a-" Her eyes went between Tenryuu's crotch and her own before she looked indignantly at her. "What is -that- supposed to mean?!"

"Now, now." She shrugged, giving Mordred a smug smile. "There's nothing wrong with having a smaller sword. They can't -all- be as big as mine, after all."

Mordred fumed before a thought visibly crossed her mind. Raising one hand, she heaved in a deep, open-mouthed breath before plunging her thumb into her mouth and blowing. Tenryuu rolled her eye, watching with detached amusement as she grew increasingly red in the cheeks, but her expression immediately fell upon seeing her length surge upward out of her swimsuit with an audible "whoosh." Smooth and thicker than her arm, it bobbed just beneath her breasts, melon-sized balls resting on either side of an overstretched bikini.

Mordred let her arm fall away, blinking away a fit of dizziness before giving Tenryuu a smug look in kind. "I suppose they all -can't- be as big as yours. For they can be bigger."

Tenryuu stared in disbelief. "Yeah, well-" She shook it off, letting indignation take over. "-well, -anybody- can do that!" She wasn't sure of that, of course, but she had already committed to taking the biggest breath she could and blowing on her thumb. Just as she was thinking about how foolish she must have looked the pressure in her cheeks suddenly abated, and there was a brief, mildly pleasurable pressure and tension in her newfound parts before her swimsuit felt increasingly smaller. The head of her womanhood rose up into view, far wider than any she had seen elsewhere. But, more importantly, larger and wider than Mordred.

She rested one finger atop it, tracing a circle around the tip. "What's the matter?" Tenryuu gloated. "You scared?"

"Of you?" Mordred asked. "No." Taking another breath she blew into her thumb again. This time there was visibly less resistance before she grew, colloquial balls turning to the size of volleyballs and her length gaining a few more inches of girth. Her face blocked from view, she was forced to hold it aside with one hand to meet Tenryuu's gaze. "Of the idea that I could tolerate such personal -mediocrity?-" Her eyes flitted down to Tenryuu's cock. "Yes."

"Oh, it is -on-," Tenryuu responded, raising one thumb to her lips.

Any thought of personal embarrassment or the absurdity of the situation was long since gone, replaced by a drive to outdo the other. Their inflating parts pressed against their thighs, forcing them to stand bow-legged on the boardwalk, stances spreading further as their balls did. Eventually a pneumatic pulse of growth forced them both to lose balance, falling mere inches only to take a seat painless. This did little to deter either of them, continuing to force air into themselves even as their feet left the floor, their views blocked by taut, smooth pillars that grew by the second.

Tenryuu and Mordred soon attracted a modest degree of attention, a crowd forming around them to watch the spectacle. As their seats rose higher they gradually backed away, the two soon sitting above the heads of the assembled masses as yards of cock hung overhead. Each puff brought with it a loud creaking, and some in the audience voiced their concerns that such balloony ballsacks and dirigible dicks would succumb to the pressure. A few scattered at this warning, but fortunately, the pair's lungs gave out before the rest of them did, leaving them ominously large but thankfully in one piece. With few other options, they were forced to resort to dizzily hurling insults.

"Now THIS would outclass BATTLESHIP cannons, let alone a measly SWORD!"

"As if a mere GUN could match the armaments of a true king!"

A coastal breeze blew, and while large, their dicks were light, stirred by the breeze. The two gave gasps as they swayed, undersides stroking against each other, their increased size bringing with it an increased sensitivity. Tapping, brushing, and soon stroking with their own hands; the stimulation reached a climax, and soon, so did they. They trembled briefly as they bulged, blasts of air shooting out of their tips as they lifted off, rocketing skyward in a series of uncontrolled loops as bystanders ran for cover.

From her seat near the window, Ryuko turned the flyer over in her hands. Describing Sword Tomboy Island as having "expansive facilities" seemed like an obvious tip of the hand in hindsight.

Suddenly Faris kicked the door open, stabbing the base of a large can labeled "Juice That Makes Your Tits Enormous" with a rondel dagger. "AVAST YE, WATCH HOW FAST I SHOTGUN THIS HERE DRINK!"

"What-"

Two seconds later the bungalow exploded into boobs.
