Reika awoke and found that she was thirsty. She hadn't had a drink since she got here, and it was the third day already

Maybe it was because she and Chiho drank Hiro's cum? Was his cum biological anyway, as he said his whole body had been replaced with mechanical parts

She looked around and found that they weren't attacked at all last night. Maybe the many dead bodies of giants and that of a dead dragon scarred off whatever monsters were lurking

She looked at Chiho who looked to have recovered, but she was still suckling on Hiro's cock

"Hiro?" she suddenly said, seeing that he looked lifeless

Chiho woke up and found Hiro's cock in her mouth!. She moved to get up and the large scab covering half her body and whole arm broke off her body, revealing her skin as good as new!

"What happened to Hiro?" Chiho asked

"Hiro are you alright?" Reika asked

Hiro looked at her robotically and could barely say "Wa...ter"

"Water? I'm thirsty too" Reika thought as Chiho was confused since she had been drinking cum all night

Chiho tried to pull Hiro up, but found that he was incredibly heavy

She touched her dial to grow, so that she would have enough strength to carry him, but Reika stopped her

"Let's not attract other airborne monsters. I'll lift him" she said, knowing that she was strong enough with her Gantz body to carry him

They avoided all the rotting bodies of the giants they killed yesterday and started walking the jungle looking for water

"Strange, he said that with his mechanical body, he doesn't need to eat anymore. But he didn't say anything about needing to drink" Reika said

"But I'm strangely not thirsty" Chiho said

"You've been drinking his cum all night. I did too the night before, but I'm feeling thirsty already today" Reika said

Chiho realized that she was right and nodded her head

"Oh no. You don't think he'll die do you?" Chiho asked

"I... I don't know. But if a human doesn't drink for 3 plus days, they'll die" Reika said

They searched for a few hours, but they couldn't find any sources of water, and by now Reika was extremely thirsty too and Chiho was starting to feel thirsty

"I hear that in the military as recruits, some of those enlisted have to drink each other's pee as training in case they are ever in a situation where they have nothing else to drink" Chiho said

"Where did you hear that from?" Reika asked as she made a disgusted face

"I swear! My friend had enlisted before he ultimately quit" Chiho said

They looked at Hiro, who had been quiet for a while and Reika took a decision and lay Hiro on the ground

"Are you seriously doing it?" Chiho asked

"What choice do we have?" Reika said as she squatted on top of his face

She squatted with her pussy about an inch from his mouth, but there was no movement

"It's not working" Reika said

"You maybe have to pee first" Chiho said 

Reika closed her eyes and imagined letting go, as she felt she was rather thirsty herself and probably didn't have any pee

Suddenly, Hiro moved a bit and lifted his head as his tongue licked her

She was so shocked that she sat down on her knees, completely smothering his mouth with her pussy as she let loose a trickle of pee directly into his mouth

He was so thirsty, he started licking her, trying to get every drop from her as she moaned at the sudden pleasure

Chiho was surprised too as Reiko stopped peeing but instead started cumming onto his mouth

She bent over in orgasm and suddenly something large slapped her face

She looked up and somehow had already expected his large cock and she immediately started sucking him in a 69 position!

Whatever little water that was in his system shot out of his cock as Reika found herself greedily drinking his cum

Before long, she had stopped peeing and had finished drinking cum from his cock as she lay on his body

She got up and looked at his face between her legs

"Are.. are you ok now?" she asked as she got off his face

"Mo..more" Hiro said weakly and rushed to Chiho, who didn't resist as he gave her cunnilingus as she sat on the ground

She immediately started peeing into his mouth as he drank it all up

After a while, there was none left, but at least Chiho had more pee than Reika after having drunk cum all night

Hiro got up as Chiho looked at him, licking his lips

"Are you alright now?" Reika asked

He remained quiet as he extended his arms and his arms opened up revealing the mechanical parts inside

Suddenly, steam shot out of his body and both girls closed their noses because it stank quite badly of ammonia

"Sorry about that. My body has to distill your pee and release the waste" he said as his body returned to his normal human looking self

Chiho walked up to him and gave him a kiss on the cheek

"Thank you for healing me" she said and she turned away, afraid it might go further

"Ahem.. anyway. I think we should still be looking for a source of water. I don't think we have any more pee to give you, and we are both very thirsty ourselves" Reika said, even though she had some cum just only

Hiro flew into the sky, able to scout from a higher vantage point

"Over here" he called telepathically. Reika and Chiho were surprised that he could talk to them telepathically, but they listened and Reika started leaping giant leaps towards his direction, while Chiho grew large enough to walk over the trees, being careful to avoid any airborne monsters flying around

Several kilometers later, they landed at a swamp and saw Hiro dissecting a giant crocodile he had slaughtered. There were the monster's body parts everywhere

"What is this?" Reika asked as Chiho returned to normal size next to them

"This bastard leaped out of the water, ambushing me, so I blasted it with several missiles" Hiro said

The giant crocodile was at least 50 meters long and twice the longest crocodile they've ever heard of on earth

It had six legs and it's head was as large as a average sized sedan car

In the belly of the crocodile, there were several body parts, and they were human! A man and a woman by the looks of it, both also without clothes

But there were also two katanas and a large broad sword at least 2 meters long

They guessed that the man carried the large sword as his body proportions looked like he could wield such a large weapon and the two katanas were owned by the woman. But that was just a guess

But Reika was disappointed as she looked at the water in the swamp. Chiho frowned too. They simply can't drink this!

The water was covered in blood after Hiro had killed the monster, but even before that the water was nearly black and they were unable to see through the murky water

"How are.. can we drink this?" Chiho asked

"No. Surely we will get diarrhea, dysentary and die or something" Reika said

"Don't worry I can filter it for you" Hiro said

"What do you mean...." Reika was afraid to ask

"I don't really pee, you know. My body needs water to cool down my systems, but I can distill it for you to drink" Hiro said

Chiho pointed at his dick as if asking a question

Hiro nodded, looking pleased with himself

"Does that mean you can store water too?" Reika asked

"For the time being until my system needs a replenishment" Hiro said

Reika was very thirsty and she knew she had no choice, but she looked at Chiho

"We've already sucked you. It'll be water right? Not cum?" Chiho asked

"Yes. for the purposes of drinking, it will be distilled water out of me" Hiro said

Both Reika and Chiho were desperate and there was no other source of water anyway, so they nodded

Hiro used his telekinesis and started drinking from the swamp, forming a telekinetic straw as the black water moved in the air towards his mouth

As he started drinking, he suddenly expelled the impurities from his ass as the swamp dirt came out of him like he was shitting. Unlike the girl's pee which was mostly ammonia, he didn't want to process the swamp water through the same way in case it clogs his systems

"What the hell?" Reika yelled

But she could see that the "poop" that was being expelled was the same colour and smell, and that it was like solid pieces of the swamp

He pointed at his flaccid dick and Reika and Chiho rushed to have a drink as he continued to drink directly from the swamp, and his dick started pissing pristine clear water

Both girls hesitated for a short while before rushing to desperately drink directly from Hiro's cock, the first drink since they got here

They were surprised that they were indeed drinking distilled water and they greedily drank as much as they could

Having had their fill, Reika pointed Hiro's penis at herself and Chiho and started washing off

They had been covered with grime and dirt after fighting and travelling for 3 days, that the water was refreshing as it was the first shower they had taken since coming here

"You don't mind to you?" Reika asked Hiro, who was still drinking water from the swamp and expelling the dirt out his ass, aiming and shooting several feet away from them the dirt from his ass

"Just help clean me as well" Hiro telepathically said

"How about your... inner parts? Can they get wet?" Reika asked

"Don't worry. I'm quite water proof" Hiro said

Reika nodded pointed his cock at him and Chiho helped wash him down and hosed his ass, that was continuously shitting out swamp solids

The girls were already clean but drenched with their hair all wet, while Hiro himself was being hosed by his own "pee" as Reiko sprayed him with his flaccid but still sizeable 6 inch penis after it shrunk

"Well what do we have here?" A man laughed as he walked out of the forest, seeing the whole episode of Hiro peeing all over Reika and Chiho

Behind him was a woman who had an equally evil smile on her face

Hiro frowned, as somehow he automatically telepathically looked to where they were. Why were there 6 minds he read, while he only saw 2 people there?
