They chatted all night, chatting under the light of the campfire that they had built, several miles away from the scene of the monster's nest

The stench of death would probably attract more monsters at night, so they didn't want to stay there

They managed to hunt something like an alien deer and had kept two portions of it's leg for dinner

Hiro declined eating, as he was worried it might jam out his parts, and even though he could eat, he didn't really need it for sustenance 

Reika and Chiho on the other hand, did need to eat and as they exchanged their stories, they started getting to know each other

Hiro told them about his body having an alien craft crash into him and them rebuilding his body. About needing to kill to feel alive and all the troubles it caused, and him ultimately sacrificing himself to destroy a meteor crashing into the earth

Reika on the other hand, found that she could talk about her Gantz past, and about her experiences, acting as part of some alien hunting group from all over the world called Gantz. She explained that she had a lover called Kei Koruno, who was the leader of her group of Gantz hunters

And although her powers change somewhat, she conjured a Gantz sword to show them and Hiro examined it and found that the Gantz sword could cut though his supposedly indestructible skin

Chiho took the sword and tried to bend it as she grew to merely 20 feet tall but returned it to Reika after failing to put a dent in it

She started explaining how she met a future man who stuck the dial on her right wrist, which enables her to grow up to 300 meters tall, with strength and durability to match her size. She could also shoot beams from her hands like ultra man in her childhood days

She mentioned that she had a younger guy called Rei Yokomamada, but she didn't mention that he was 16, a few years younger than both Reika and Hiro who were 18

They found out that although Reika and Hiro died at the same age, Reika died a year before, making her actually one year older than Hiro. And Chiho had her experinces and death several years later, but if they compared years of their birth, she was actually the same age as Reika

"Kei... Rei,,," Hiro said, muttering the lovers of both girls

"How about you? Did you have a... lover too?" Chiho asked

"I had feelings for a girl called Shion Watanabe, a classmate who hid me in her grandmother's house when the police was looking for me. I think she liked me. She was.... someone I had to protect when the meteor was going to destroy the earth" Hiro replied

"So she's not your lover? I mean you never..." Chiho asked and did a motion where she used her right finger to poke into a ring she created with her left finger and thumb

"No! No..." Hiro said as he looked into the distance

"Does that thing still work as a sex organ?" Chiho asked, pointing at his flaccid penis

"I don't know. Maybe. But if it moves, it's from my will, not from arousal" Hiro said as his penis rose into the air at his thought

Chico quietly admired his penis, noting that it was longer and thicker than her boyfriend Rei's. It was even larger than her previous boyfriend Ryoji's cock, and he was a big and muscular man. In fact, it's comparable to the very largest freak's she's fucked in her career as a pornstar

Reika blushed and looked away as well, as Hiro's cock was definitely larger than Kei's in her mind

"Er.. that would hurt. You can put it away now" Chiho suddenly said

Without saying a word, Hiro's cock shrank again, but surprisingly, it suddenly reversed and grew back to it's maximum size

"Hey, what the ?" Reika asked

"I don't know. This has never happened before"  Hiro said, looking at his penis that was at least 8 inches in length

"Then why.." Chiho asked

"Maybe because the number 1 idol that I admired and my favourite pornstar are naked in front of me.." Hiro said and realized how embarrassing it was to say that out loud

Chiho suddenly grabbed his cock and started masturbating him

"Does this help" Chiho asked

"Ye..yes" Hiro said and leaned back as he enjoyed Chiho's handjob

Finding that the cock was so long, Chiho started using both hands to pump Hiro's cock

Reika subconsciously was touching her breast and her other head started touching her pussy when she saw them

Hiro got even more aroused when he saw Reika touch herself and his cock twitched in Chiho's hand as he lay his head on the ground to enjoy Chiho's ministrations

He reached out to touch Chiho's breasts, when she pushed his hand away

His hand instead went between her legs and started playing with her pussy, first gently playing with her pussy lips, before inserting his finger into her wet pussy

Chiho moaned and Chiho suddenly opened her mouth to suck him

She was amazed, as she had sucked such a large cock once or twice before in her porn career, but it was nowhere near this hard

Having all the sensations of his human self being emulated in his robot body, Hiro felt Chiho's mouth and it was the first time he had ever received a blowjob, having died a virgin

He wondered why he never did anything sexually to his victims before or after he killed them. That girl in the first house he randomly massacred was quite pretty. He could easily have used her body sexually

Chiho moved her body and moved her pussy towards his face as she sat on her face as they gave each other a 69 

Reika by now was already openly masturbating, while watching them give each other oral sex

Chiho looked up and saw Reika pleasuring herself

"You want some of this?" she asked as Hiro's cock popped out of his mouth and she used it to point at Reika

Reika wanted to say no, but instead she crawled directly over to them and started sucking on Hiro's cock while Chiho continued to pump it with both hands

Reika was shocked as she had to really open her mouth with to get even the tip in if into her mouth

Suddenly, he ejaculated in Reika's mouth, and the force of his ejaculation was so powerful, her head was propelled away as her body was shoved to the ground the other way

She got up from the ground, shocked at the force of his ejaculation. It had the force of a firehose

Chiho, who still had his cock in her hands was shocked as Hiro's cock continued shooting into the air like a fountain, covering her and the area all around with cum

Hiro's tongue suddenly started vibrating and Chiho was caught by surprise as she started cumming onto Hiro's face

Reika got up and was shocked to see Chiho's eyes roll up as she orgasmed and Hiro inserted his tongue into her pussy and continued vibrating

After orgasming several times, Chiho got off his face and blocked her pussy with her hands

"No more.. I can't take it. I might end up fucking you" Chiho said as she pleaded with him

Hiro looked at her, quivering with her face flushed with blood and looked at Reika, who had continued masturbating

"What?" Reika said as she looked at Hiro, suddenly embarrassed that she had been caught masturbating again

Moving suddenly, Hiro was between Reika's legs and his face was directly in her pussy

His tongue darted into her pussy and started vibrating at high speeds as she screamed in pleasure

He tasted her juices as she squirted into his face several times, orgasming over and over

He got up and placed the tip of his large cock at her pussy, preparing to fuck her

But Reika had the presence of mind to grab his cock

He was shocked as the strength in her grip told him that she was serious

"Enough Hiro. Let.. Let's stop here before we go to far" Reika said

He looked at Chiho who had now regained her composure and had placed her hand to block her pussy and showed him a wagging finger to say that it was time to stop too

Hiro got up, still unsatisfied and he walked over to a tree and started masturbating himself

Before long, he was drenching the tree in cum before he finally managed to get his cock in a flaccid state again

He turned around to see Reika and Chiho sitting next to each other watching him masturbate from the back

"Are you ok now?" Reika asked

"Ye....yes" Hiro said, a bit angry that he had been teased like that.

"We don't mean to tease you. But it was a mistake" Chiho said

They continued in an awkward silence, as there were large puddles of his cum in several places, and both of the girls were splashed with cum too, and there was no place to wash off

Later that night, they took turns keeping watch while the other two slept, now that they could reasonably rely on each other to keep them safe

Reika decided to take the first watch and armed herself with her Gantz Pistol and a Gantz sword, still finding it strange to summon them from a beam from her eyes. She tested that she had her Gantz suit given strength on a nearby tree before sitting by the fire as Chiho and Hiro slept

They slept apart, but next to each other. Hours later, Reika went to them for Chiho to take the second part of the night and found Hiro hugging Chiho to sleep, his erect cock poking between her butt, though he didn't fuck her

"Chiho!" Reika woke her and Chiho was shocked at the large cock rubbing between her butt cheeks and quickly got up and took the next shift

Reika lay down but at a few feet away from Hiro. Hours later, Chiho went to wake Hiro for his turn, and found Hiro fucking Reika thighs, having intercrural sex with her

"Hey, you asleep?" Chiho asked

"Hard to sleep with this happening" Reika said as she felt the large cock rub against her thigh and her pussy lips

She nudged Hiro who got up and looked around

"Your turn" Chiho said as she laid next to Reika who finally got some sleep as they hugged each other to sleep

Hiro looked at the two beautiful girls and sat by the fire to keep watch. But he looked at his fully erect cock 

"Damn" he said to himself and started masturbating, looking at the two beauties hugging each other to sleep
