“How fascinating…”
 
Robin mused at the stone engravings on the wall. They looked similar to Poneglyphs, yet were entirely different at the same time. She had never seen anything like them anywhere else, it was rather mind blowing!
 
Robin leaned against a tree and mused. She still had a year left until she was to meet up with her crew and sail to the New World. While her current duties as a revolutionary kept her busy, she was still able to sneak away every now and again to go on an excursion. This time, she chose to go to Amazon Lily, an ill-explored island to outsiders. She had expected to find some ruins, but something like this was on another level!
 
After looking over her notes, Robin leaned off the tree to examine the stone again. It was then that she noticed something sticky had coated her hair. No, not only her hair but her entire backside. She let out a noise of disgust and ran a hand through her scalp. That tree must have had sap on it. She looked at her hand, realizing it wasn’t sap. No, it was a lighter color, and it smelled horrible. She sniffed her palm a few times and her face went white as she realized what it was.
 
Semen.
 
Robin slowly turned around. That wasn’t a tree she was leaning on. It was a penis. A penis the size of her body and caked with old, unwashed spunk. The cock was attached to a massive, slender green figure. It looked to be a snake but with a human upper half and a pair of hulking breasts. The snake was asleep, silently snoring without a care in the world. Robin couldn’t believe it. How didn’t she notice the smell? Or the fact that she was leaning on a penis? And most puzzling of all, she knew who the snake was.
 
“S-Sandersonia?”
 
The snake lady opened her eyes and sat up, a yawn shaking the trees and scaring off nearby critters. She looked down at Robin with wide eyes, her penis starting to harden as she saw the visitor.
 
“Ohhhh… Hello Robin!” Sniff sniff… “Damn, you smell pretty bad… Wait, did you-”
 
“I-I apologize,” Robin replied, a blush spreading along her face as she took a step back. “I didn’t realize you were there, honestly. You just… blended in.”
 
Sandersonia flicked her tongue. “Aheh, don’t worry! I can’t blame you one bit~ Most ladies can’t keep themselves on my cock anyway! They’ll spend hours gropin’ at my balls, rubbing their bods on my shaft~” She explained, licking her lips as she reminisced. The tip of her penis began to ooze a bubble of nasty fluid, splashing onto Robin’s feet.
 
“Eck!” Robin gasped, freezing up as the warm, sticky goop hit her foot. She knew that this island had some unique customs, but to be so… open about one's body was something she didn’t expect. “That’s quite… interesting? But I assure you, I was just looking at these strange markings…”
 
“Hmm?” Sandersonia asked, leaning over Robin to look at the stone. “Oh right, Zoniglyphs!”
 
“Oh? Can you read them?”
 
“Oh yes, I hear they’re a distant cousin from those poneglyphs you love so much! I’m a pro at transcribing them, maybe the best around!~”
 
“Perfect! What does it say?”
 
Sandersonia gave a devious smirk, raising to her full height. She towered above Robin, her rock-hard member hanging above her face. “Now hold on, I don’t think I can focus when I’m so… pent up!” She replied, patting her crotch. “Help me drain my nuts, then I’ll read it for ya!”
 
“W-What?!” Robin gasped, her face now fully red. She gawked at the cock above her. The smell of unwashed cum wafted down, the sheer heat and thick musk making her sweat and gag. The nectar coming out of it was almost sizzling hot, it was by far one of the most disgusting penises she’s ever seen! Not… Not that she’s seen very many, of course.
 
“B-But it’s so… unclean…”
 
“Hm?” Sandersonia blinked, tilting her head. “What’s wrong with that? Kuja don’t wash their cocks! It’s unnatural!”
 
She wanted to refuse, to keep her dignity and not get her womb split open by Sandersonia’s cock. But, that stone taunted her. She may never get another chance like this! “Very well, if that’s what it takes…” Robin sighed, beginning to unbutton her top.
 
Before she could even undress, she was bound by Sandersonia’s tail. The snake lifted her up, tail compressing and poking at Robin’s breasts. Sandersonia flicked her tongue again, positioning Robin right above the tip of her eager penis. “Don’t worry about undressing, silly! You won’t be able to get those pants back on once I’m done with ya anyway!”
 
“W-Wait, but I just bought thes-”
 
PLAP! RIIIIIIIP!
 
Robin let out a squeal of intense shock as she was jostled down onto the head of the penis. Her legs spread wide as Sandersonia’s dick pierced through the fabric of her pants, causing it to rip at the seams and fall clean off. Robin felt her pussy get forced wide open from the cock, an imprint of the head slamming through her belly. “AGH! I-IT’S HUGE!”
 
 
“Heh, don’t get too eager now, it’s not even halfway in!~” Sandersonia giggled, a look of desire in her eyes. She began to bounce Robin up and down with her tail, every thrust pushing a few more inches down the rotten mast. Robin was too caught up in the sheer size to notice at first, but as her vaginal walls were reshaped to fit Sandersonia’s dick, she realized even more than before just how nasty it was. Grime caked her thighs and innards, smegma getting packed tightly into the folds of her vagina. The musk battered her nose and her long hair became even more soaked in the reproductive sap. It was truly vile, and yet…
 
She didn’t hate it.
 
Sure, the feeling of her body being tented open wider than what should be possible was beyond imagination, but it was still sex. And it felt good. Her pleasure points were getting pounded into oblivion, and the feeling of her legs dangling and her womb being invaded by dick was quite remarkable. It was way deeper than Nami had ever been able to go in her by a long shot!
“Ah!~ Ah!~” She cried, gagging and coughing between bounces. Sandersonia gave a mighty howl before pulling HARD, sending Robin balls deep down the shaft. Her belly was punched out to twice her height and then started to rapidly bloat and round out as her womb became flooded with hot, steaming spunk. It poured out of the crevice between her pussy and Sandersonia’s cock in doves, splattering over the snake’s tail and the stone below.
 
“Yeeeees!~ Take it all!~” Sandersonia moaned, thrusting into Robin a few times until her flood of spunk came to an end. With that, she yanked Robin off of her dick and carefully laid her between her oversized breasts. Her body was well-rounded, and her pussy was gaped open from the fucking. Robin felt like she was about to pass out, but as she basked in the afterglow, she gave loopy, horny giggles.
 
“A… Ahah… O-Oh my, that was…” She groaned, slowly sitting up. She felt the semen inside her slosh, still busy pouring out into Sandersonia’s cleavage. There’s no way she’s not getting knocked up from that. “S-So, can you tell me what the stone says?”
 
“Hmmm?” Sandersonia asked, her tongue flicking once more. “Who said we were done?”
 
“W-Wha?”
 
Sandersonia’s cock was still rock hard, and her tip began to leak once more. “I said I’ll read them to you once my nuts were drained, and they’re far from empty~” She smirked, her tail creeping up and starting to slowly wrap around Robin.
 
“O… Oh my-”
 
PLAP!
