Another universe heard from. This is a realm that doesn't lend itself so readily to inspiration to me, but every now and then an idea will come that's worth writing down. This one's actually made it to action, so it's got a rather privileged position among those ideas.

It was a fortress on the borders of the Koopa Kingdom, far enough from the centre that it operated pretty much on its own, yet close enough to leave no doubt as to where their allegiances lay. Right now all was pretty quiet; Bowser's latest plot had been foiled once again, and the king of the Koopas was still stewing about it, not yet ready to engage in his inevitable next round of shenanigans.

With no fear of an imminent attack, all was going into shoring up the fortress defenses. A pair of Koopa Troopas was patching up a crumbling corner, under the watchful eye of a Koopatrol with a severe look on his face. The grumbling from the two smaller turtles left little doubt that this was not volunteer work.

The last of the material they needed was suddenly dropped right next to them, the loud clattering startling the two and causing them to glare up at the deliverer, a purple-shelled Hammer Bro that towered over them. "Watch it, bozo!"

"Blow it out your tailpipe, whelp."

"What he said," the Koopatrol snapped, then looked up at the Hammer Bro. "That'll be all, Octave, thanks for the help."

"No problem, chief." Octave wasn't the one in trouble, but the heavy lifting often came his way. He was built much larger than the average Hammer Bro, a fact he attributed to his father being a Sledge Bro. A crossbreed like him didn't tend to sit well with everyone, though few had the guts to bug him to his face. But here, he was in familiar territory, and they were happy enough to have the extra muscle around...especially since few at the fortress had the kind of strength he did, meaning anything weighty tended to be hard to deal with.

"We may need your help more when the north wall inspection is done. You're off until then, but don't go too far."

Octave smirked. "I won't. Just gonna make a trip down to the dungeons, pay our prisoner a visit."

The Koopatrol gave him a look. "The prisoner? To what end?"

"Nothing, Chief. Just a little chat, see if I can't get his tongue wagging."

"Hm. Well, it's doubtful he knows anything of use, but do let us know."

Octave nodded and headed off, as the Koopatrol started snapping at the workers to step it up. A sly smile crossed his face as he returned inside; with any luck, wagging wasn't going to be what that tongue would be up to...


Usually he thought of dungeons as having bars and such. Empty rooms with heavy iron doors wasn't quite what he had been expecting. Then again, being captured in a dungeon wasn't, either. Especially not in the state he was in...

The salmon-colored Yoshi sat on the floor, staring off into space. Pallet was his name, but he didn't know how much longer that would matter. He shouldn't have strayed so close to hostile territory, but the temptation of the berries he had smelled was just so strong...then again, even that had ended up a bad idea. Now he was down here, no shoes, no saddle, just a collar around his neck, to prevent him from swallowing anything big enough to be a guard. Not that he could at the moment anyway.

His tongue snaked out of his mouth, his fingers running across it. Normally it would be sticky, tough, perfect for catching prey and drawing them in as Yoshis were wont to do. But the berry he had eaten before being captured had altered it, making it soft and slick. Useless for defense...perfect for wrapping around a thick cock. Well, his kind called them 'slutberries' for a reason. Look before you lick, the rule that he too often ignored, and it had definitely come back to bite him this time.

He had no idea how long the effects were going to last. Already it had been long enough to get him captured, and for the ones who got him to force him to use his altered tongue for some fun. The worst part was that he hadn't really minded that...okay, so he was a bit of a slut naturally already. What was so bad about that? Enjoying the physical pleasures of life was just one reason to live. So what if he enjoyed them a touch more than most? Still, it hadn't been enough to convince them to leave him be.

But the one huge Hammer Bro...the whisper in his ear as he carted Pallet to the fortress, his promise of a good time under certain conditions...Pallet knew he probably shouldn't indulge them, but there was a thrill in the idea. Locked in a dungeon, devoid of his typical defenses, faced with a captor whose size was incomparable to Pal's prior experience...well, it wasn't like he had other plans at the moment, and his own dick being wide out in the open told him all he needed to know about his body's opinion.

Almost automatically, his tongue extended farther, curling around him as it did. Pal let his arms fall to his sides as is wrapped around him, coiling and pinning the limbs to his sides. It was no wimpy wrap, either, as a second revolution held him fast, unable to move an inch unless he loosened it. But loosening it wasn't the idea; the Hammer Bro had had a specific idea in mind, and Pal felt himself blush at the idea of it. But he went through.

The end of his tongue slipped under one of the coils around him, and some deft motions sent it squirming around on itself. Over, under, and through...his tongue was wrapped up in a knot, and he flushed harder as he pulled the end of it taut, the knot secured with an almost uncomfortable tightness. Now he was really bound, beyond his ability to undo. He couldn't pull out of the knot using his tongue alone, and with his arms immobile, he had no way of reaching the spot to try to undo it. The only part he could move was the slack at the end...just the right length to wrap around his own cock. He let out a squeak as it did, at the sensation, hard to get used to...Yoshis used their tongues for this a lot, but their regular tongues didn't feel like this, not nearly as good.

It had to be a sight...helpless and teasing himself, just as the Bro had commanded of him. And as he heard the heavy door open, he could see the form of the big guy standing in it, clearly pleased with what he saw.

"Well, well...looks like you did as I asked. That's good, that means we'll have our fun."


Octave shoved the door shut, the click of the lock sealing him in. Of course, he had the key, but he wasn't going to need it for a while, and he would rather no one just suddenly drop by and get in when he was occupied. Satisfied, he strode towards Pallet, feeling himself get mightily aroused by the sight before him. The positioning couldn't have been more perfect - that tongue wrapped firmly around him, leaving him helpless, and his legs weren't really trying to make up for it, splayed out to show off that delectable tailhole of his.

"Impressive...you know how to turn a guy on." Octave was showing it, too, his staff well on its way to its full size. To Pallet it was terrifying and tantalizing all at once, something so big seemed out of place on him, but he couldn't imagine not having it at least once. Then again, he knew what they said about turtles...the others tat had captured him and used his mouth were a pretty good size too, though not coming close to this.

Octave soon stood over Pallet, at full size and already dripping a bit in anticipation, the drops deliberately poised to fall onto the Yoshi's tongue, making him whine a bit at the intensity of the flavor. "I actually find it interesting that you were like this. Your tongues can't normally knot like this...but those berries make them soft enough that they can, I see." He bent down a bit and rubbed his cock up against the exposed prats of Pal's tongue, the taste sending shivers through Pallet - so much stronger, so much more male than his own.

"You looked so worried when we caught you like that...knowing you couldn't do anything except service us. When one of the guys said we should send you off, though, see who else might prey on you, I saw the flicker of terror in your eyes. You didn't think you could last on your own, did you? Thought that being captured might give you time to recover...get yourself back to normal."

Panting and red-faced, Pallet nodded slowly. Those thoughts had crossed his mind...after all, at least in the dungeon, he knew what he would be up against. It didn't make being captured any rosier a prospect, but it seemed less frightening than the unknown.

"Was that what you were thinking? Stay down here, nice and safe until the effects wore off?" Octave leaned over his head, his voice dropping almost to a whisper. "They only last a couple of hours. When you knotted yourself up like this just now, that was all your own. You wanted this, bad enough that you kept yourself from changing back."

Pal's eyes widened at that. Could that be true? Maybe the Hammer Bro was lying to him...but he'd heard stories, warnings of Yoshis who had become sluts like that, their bodies changing further rather than returning to normal, making them perfect fucktoys. They never said whether it was for good or not, but that prospect was very real...a part of him shook with fear at the idea that he could be stuck like this for good.

Only a part, though. Another part was excited at the prospect, eagerly welcoming this perverted subversion of himself. He'd already been pretty easy...why not go the whole way? Especially for a stud like Octave, whose dick he'd been thinking about since...well, since the event leading to his capture. The Hammer Bro had definitely been lingering on him, promises of a good time on his mind and the taste of him on his tongue.

He didn't struggle or resist as he felt Octave drag his length down across his body, the taste remaining potent on his tongue. He felt the end of it wrapped around his cock give a few unbidden pumps, getting a moan from the Yoshi that didn't miss Octave's ears. He let out a quiet laugh. "Enjoying this more than even you expected, I bet...and we're just getting started. What comes next is gonna drive you crazy."

He settled at Pallet's wide open tailhole, the sexy reptile's legs spread for him without even needing a command. Octave knew this Yoshi was far from inexperienced, but none at the fortress had yet taken him like this, and he was fairly certain that he'd be the biggest one ever to use him, judging from Pallet's shock at his size. Pressing up against the hole, he could feel it twitching, almost begging for him. A solid thrust buried him partway in, that tailhole squeezing and tightening wonderfully around him.

So deliciously big! Yoshis were made to stretch, made to enjoy it, and he was very much enjoying it. Squeaks and squeals, all he could do with his tongue in this state, accompanied every thrust deep into him, sending thrills throughout his body. Gods, he was more sensitive than ever back there, his body responding fantastically to the intrusion, rapidly silencing his reservations about succumbing to his new sluttiness. His tongue was slurping involuntarily over his own cock, adding to the sensations as best it could.

It was even better than Octave had anticipated. That ass was so tight despite its frequent use, no doubt because he was just so big, but it yielded without argument to every thrust, allowing him deeper and tensing dutifully to maximize the feelings of pleasure. He'd had a few dalliances with other members of the Koopa Kingdom but none of them compared to this! Quiet grunts emanated from him as he struggled to keep from going off too early...damn, the Yoshi was a test, and he slowed himself down to give himself an edge, aiming for deeper and stronger rather than faster.

Soon he encountered a tighter point inside Pallet, a spot that actually did fight him, prevented him from entering at his slow and steady pace. He still had more to give, a quarter of his cock still left outside the Yoshi, and there was no question he wanted it all in there...

Pal flushed even deeper. That was his egg chamber that Octave was pressing near, the part that trapped their swallowed enemies...but it was dormant now, thanks to his inability to swallow anything. He'd never had anyone large enough to threaten to bypass it...but he'd heard a few stories, Yoshis going as far as to give themselves to the Koopa King just to have the experience. It was supposed to be wildly pleasurable, a hundred times better than the rest of him, but also permanently altering...and he was certain, deep down within him, that if Octave took him that far, he'd never be able to go back, the pleasure would erode his will to return to normal. He'd be a permanent Yoshi slut, his tongue forever soft, unable to refuse any cock and eager to demean himself to get laid. And he knew Octave knew it...the Hammer Bro priming himself to enter, watching him intently to see the conflict in his head, eager to strip him of his last vestiges of defense...

He let out a squeak and tightened down on the large intruder as he came hard, cum spurting all over his body and tongue, some even ending up in his mouth. As he tasted himself, he became aware that his tongue had brought him to climax, his arousal fueled by thoughts of his outcome. Only then did he understand that he'd already made his decision - his tongue had told him all he needed to know, he wanted this, wanted Octave to ravage him and drive him into a frenzy of pleasure, wanted the consequences that came with it. Eyes closed, panting, he gave a small nod, a message to Octave to break him.

The next moment heard an ear-piercing squeal from Pal as Octave drove himself in to the hilt, crashing through that inner sphincter and filling his innermost sanctum. Gods, it wasn't a hundred times better, it was a THOUSAND times better, pleasure he couldn't even comprehend flooded his mind as that cock filled and stretched that underused spot, responding in its newly modified way to the Hammer Bro that broke him. He was spurting again in seconds, thrashing as a pleasure that just wouldn't end overpowered him as thoroughly as Octave, maybe even more.

It was something else for the Hammer Bro, too. Not just from the satisfaction of fully embedding himself in his partner - a rare event in itself given his size - but also the unexpected sensations at his cockhead, a mild tingling that sent sparks through him, rewarding him for stripping away the egging capacity. He was moaning out loud himself, lewd sounds that weren't typical for him, such was the intensity of the pleasure, and he was in no way holding himself back now, ramming in hard and fast and not caring how long he lasted anymore.

It wasn't much longer at that rate, the pleasure simply too much to handle. With a guttural cry, he slammed in one last time, pumping Pallet full of thick Hammer Bro cum, eliciting another squeak from Pallet as he felt his chamber filled in a different way, no less pleasurable but certainly not like anything he'd ever felt before. The Yoshi had pretty much been in a constant state of orgasm from the time of his deepest invasion, and had nothing more left to give from his own testes. He now laid there, panting and tingling, the potent pleasure not letting up but not quite bringing him back to the top anymore.

He felt rough hands undo the knot in his tongue, allowing him to pull it back in, finally loosing himself from his bonds. Tired hands found Octave's arms, and he was surprised to find the gesture reciprocated. The Hammer Bro descended on him, his own, much smaller tongue entering his mouth, coiling around his own lazily. Pal's eyes lidded as he lost himself in the kiss, at perfect ease with the turtle above him as he felt the swelling within him dwindle, his load finally complete.

It was better than Octave could have imagined, and he knew that this wouldn't be the last time this happened, for sure. But he wouldn't have to be trapped down here for in next time. Pallet was his, but he had no mind to abuse that. He cared for the Yoshi, wanted him, not just a slut to play with. As open and willing as he would be, Octave would protect him, ensure he wouldn't ever come to harm.
