"Syyyyyyrrrr..."

"Mary? Is that you? You look, uh... Different?"

"Naaaaah. Not different at all. I just found a good treasure thanks to Cagliostro. You know, she's such a sweet lady. I think you'd like her too, Syyyyrrr..."

A strange encounter was taking place aboard the Grancypher. An encounter between two siblings that loved to adventure. Two siblings that had joined up with the captain of the Grancypher because they believed that he could help them get closer to the treasures that they both wanted to find. But there was definitely something wrong with one of the siblings, because she was a lot more top heavy than she had ever been.

The girl that tried to find all the treasures that dotted the skies was named Mary. And the thing that seemed so off about her was the lack of her hat. Well, that wasn't actually the thing that was wrong, but the horns that had taken the place of her hat certainly were. They were so long, almost a bit too thick and phallic, and they only served to bring more emphasis to the breasts that she liked to show off. Those breasts were way bigger than her head, to the point where she was being weighed down by them. Combine that with the fact that she wasn't even wearing her usual coat, preferring to go with a cute golden sling bikini that Cagliostro had picked out for her, and there was no better thing to call her than a Draph Slut. Which she definitely didn't see herself as, but she didn't really know what it meant either.

Her brother, Syr, was really just shocked at what he saw. The girl that had helped him meet the captain had now turned into a perverted parody of those nice ladies with all the horns. Then again, considering what he had heard from the captain, this wasn't really that far from what they were like when they ended up in heat. So maybe somebody had stuck draph horns on her and gotten her into heat. Had she allowed this so she could get to go on really big adventures? He didn't know, and he honestly still didn't know how to handle what he was looking at.

"A treasure made you this big?" Syr asked, before nervously rubbing his cheek a little. "I mean, you're kinda big on your chest, but you're also really short now." He had to be hnest, because they were nearly looking into each other's eyes. She was so compressed that he was worried that she wouldn't be able to fire her guns. Which she really needed to do if she ever got into trouble on one of her adventures.

Mary nodded, her big tits bouncing in tune with her nodding as the string bikini did very little to try and keep them stable. How would anything ever come close to keeping those massive mounds stable, anyway? "It's fiiiiiine. It means I can do thiiiissss!" She cried out, right as she very suddenly and almost violently wrapped her arms around her little brother.

Syr was caught completely offguard by this sudden attack. He was pulled deep into those mounds, his body practically getting slurped right into that gap. It was tight. It was sweaty. It was smelly. And it made his head get all sorts of foggy. "M-Mary..." He muttered, he couldn't even manage to tell her to stop because it was way too hot in there. So hot that his pants started getting all sorts of tight...

"Ehehehehe. It's okay. You can have these too, Syyyyr." Mary chimed as she slowly started pulling him right back out of her cleavage. "You can be juuuuust as big as me. And then we can boooooth pay back Cagliostro. She said she wouldn't change me back after what I broke if I didn't help her raise a bunch of money, ehehehe..."

Syr could just barely understand what his big sis was implying. She had probably broken something again, which was why she ended up being this big. And since he had heard so much about what Cagliostro was willing to do... If he was able to be worried, if his mind wasn't currently a big ol' haze thanks to the warmth of being inside that cleavage, he would've probably tried to go beg Cagliostro just to turn his big sis back to normal.

But instead, all that he could do was just shake a little. Maybe even nod. Even though he really shouldn't nod. Because that meant that he was agreeing to whatever his big sis was trying to get him involved in. This wasn't an adventure that he wanted to join in on. He didn't want to end up like her, at least not if it meant that he'd end up just as airheaded.

Mary grinned from ear to ear as she reached riiiight into that cleavage of hers, pulling out an obnoxiously big potion. The potion itself was shaped after a tit, with the cork being stuck on the nipple. "Bottoms up then, Syyyyyr." She chimed, popping that cork right open as she grabbed ahold of her little bro and stuffed that oversized glass tit straight into his mouth, making sure that he drank as much of the potion as he possibly could. She wanted to make sure that he could end up helping her make that cash, which meant that he needed to be a draph that was as good as her. Or better!

Syr's eyes widened as he felt that stream pour right down his throat. He could just barely pull himself out of his haze to try and grab the tit-shaped flask out of his mouth, but his sister was really strong when she wanted to be. And that meant that he was pushed right onto his butt as that flask was emptied, before she casually tossed it off the side of the ship and left him coughing because he barely had a chance to properly breathe after swallowing so much of that.

His body immediately felt way too hot. It was like he was being pricked on the inside of his skin, and the heat inside his body increased as a result. It felt like he was being weighed down, and yet stretched out in every single direction. But he didn't feel like he was growing bigger. It just felt like he was being shifted around.

Syr let out a moan as he very abruptly started growing on his chest. His clothes, which had been hand-me-downs, started to shred apart thanks to the sheer growth happening to him. One cup, two cups, four cups, his chest was expanding faster than he could count. And the entire experience was sending shocks upon shocks through him, making him pant and moan as his chest quickly outgrew his head.

He was forced to fall onto his knees and let his hands meet the floorboards as those tits weighed him down. They were forcing him further and further to the floor, but he somehow managed to keep himself somewhat above the ground. Not that he managed to do so for long, because he felt a really big pain pouring through his head. So much so that he was forced to collapse right ontop of his brand new breasts, which forced him to let out an even stronger moan that coincided with his brand new horns popping right out of the side of his head.

Those horns marked him as a draph. And just like his sister, they were extremely wide and really easy to grip and squeeze. They were perfect handlebars, which was probably intended by Cagliostro when she made the potion in the first place. Not that he could focus on that. All that he could focus on was how hot he was. How much it felt like he was being cooked from the inside. He wanted it to stop, he really wanted it to stop. But all that he could do was very slowly try to push himself up...

Only for Mary to grab his horns with a grin on her face, causing him to let out another moan as those incredibly sensitive protrusions were stimulated. "Dooooon't worry, Syyyyyr. I'm juuuuust testing the merchandise..." Mary chimed as she rubbed her hands all across those nice big horns. They were almost as smooth and as easy to use as hers. But they were kinda soft. Which meant that if she started to shake them around a bit...

Syr could feel the feedback of having his horns played with. It was making him tremble more and more as he was forced further and further along the line of pure pleasure. It felt so good to have them played with. He wanted nothing more than to have them played with over and over and over. All while that heat inside him started to gather down below. All while the pressure inside him built more and more. It made him want to... Want to..!

The young boy let out a powerful and orgasmic moan as his shorts suddenly ripped apart, revealing his supple derriere and the brand new pair of lips that were busy drooling out everything that they possibly could. Even though he had just lost his manhood, he was drooling like he had been using them for ages.

Well, he wasn't really a he any longer. The short stature, the massive tits, and the extremely wet pussy. Syr had turned into a female draph. Every single possible interpretation of the female draph figure was on display. Especially the part where they were good for little but breeding. It wasn't something that she really agreed with, since she looked up to a lot of those horned girls, but with her mind in its current state, it was hard to think of her as anything else.

"S-So hot..." And despite the fact that she had just experienced her first orgasm as a girl, her very first orgasm as a very horny draph girl who could hardly contain herself as she absentmindedly thrust and bounced on nothing, like she was craving something nice and thick, she was still feeling such an overpowering heat inside her. She craved something that could satiate the burning need inside her. Something that could stop this pussy of hers from aching.

Mary grinned as she looked down at her sister. She had been a boy just a few moments ago, but she had certainly experienced such a powerful and sudden onset of puberty. Well, as much as you could call a magic draph potion a case of puberty. But that's fine. She could help her out, she just needed her to stand up. Something that was easy to do if she just graaaabbbed those nice hoooorns...

Syr let out more and more moans as she was raised right up onto her feet, her tits still trying to weigh her down even though she was stand up straight, and her pussy still drooling beyond belief. She really wanted to just be filled at this point, and her sensitive horns being stimulated further weren't helping things.

And though she did this as a favor to try and help her out, it also didn't help when Mary started to wrap a simple golden band around her. A band that was nice and stretchy and really tight against her body. By the time that she realized what it was, it was too late. Because the band dug into her tits and made her feel even hornier, especially as it also dug into her pussy and made her crave even more. All thanks to the very stretchy sling bikini that matched her sister's.

"Come on, Syyyyyyyr." Mary giggled, patting her fat-tittied little sister on the back. "Let's go have some fun. I hear the captain really likes draphs with their tits out!" She giggled, forgetting all about her love for adventure as she focused more on what Cagliostro had told her to do. Make lots of money with her short and stacked body.

Syr was powerless to stop her, as her mind was far too fogged up... Especially as she started imagining that nice captain without his clothes on, and... Mmmmphh... The Captain without his pants on, letting his manhood hang in front of her face...

Her want to turn back melted away as her mind was conquered by lust, and she walked side by side with her equally slutty sister. Off to have a little adventure, so to speak.

Off to go make the Captain fuck them both senseless.
