Disclaimer: First Chapter
Story Start!

'A-cup Angst, DD Dipshit, and H-cup Horny... now all we need is a girl with a chest so flat she's an actual board and all the basics will be covered.' Naruto was reading a book at the moment as he looked at the Party eating a meal together. Well, he subtly looked at their chest sizes and compared them to each other.

Flat, Medium, and Large sizes all together at a table.

He was glad none of the girls were mind readers, because it meant that he could stare at their chests in peace and quite. Kazuma was picking out a quest for them to take, something that would give a good challenge and make better money. Now there were 5 of them, a complete team by any definition.

The Strategist: Kazuma
The Lead Fighter: Naruto
The Healer: Aqua
The Tank: Darkness
The Last Resort: Megumin

They had an overall balanced party now, and while that was a much to simple way to describe their roles in combat, it wasn't a wrong way. Just oversimplified. Naruto had taken a look at Darkness' stats and saw that her Strength and Defense stats were absurdly high. Her Strength was almost a match for his own, and her Defense far exceeded his stat for that. Though, her Dexterity stat was so low that he doubted she would ever actually manage to hit anything in a fight.

"Whatcha reading?" Megumin asked as she noticed Naruto reading.

"You can read-"

Seconds later Aqua was knocked out with her face in her soup bowl, a huge bump on her head from the vicious head smack that Naruto had given her. He wasn't just some dumb barbarian, he actually did like books if they were good books. He just had trouble finding a book that suited him, so it was nice of him to find one.

"Adventure novel."

"I have read that one, the ending is-"

Seconds later, Darkness was panting in pleasure from having a huge steak shoved into her mouth, preventing her from spoiling the book for him by accident. The steak was so large and shoved deep enough into her mouth that she was choking on it, and she was enjoying the sensation of being choked.

'Kazuma, you better get your ass back here soon.' Naruto thought as he turned the page in his book. With a knocked out Aqua and a moaning Darkness, it was hard to imagine anyone else wanting to visit the table. Megumin slid closer to him and grabbed his shoulder, she leaned up so that she could see what he was reading and get a peek at the book. Since she wasn't bothering him, he moved the book closer to her so that she could read it with him.

-With Kazuma-

"An ArchPriest, an ArchWizard, a Crusader, AND a Berserker... dude, your party is absolutely stacked..."

"Yeah, too bad their flaws way outweigh their bonuses." Kazuma deadpanned in annoyance. The strongest of the group had anger issues, the one in the group with the most durability couldn't fight to save her life, the wizard could only use one spell once a day, and he could barely stand Aqua and her dumb antics screwing things up for them constantly. 'Frog Quest... seems fine I guess.' Kazuma picked out a quest.

He wondered if he could take this quest with Naruto alone.

Nah, if Naruto went rage mode then he wouldn't be able to stop the guy at all. He would need to take at least Megumin along so that she could blow him up... calm him down. At that point, he should take Darkness as well so that she could tank his rage... and Aqua so that he would focus on her more than the rest of them.

'Naruto and my luck stats balance each other out... but with the others around, it tips the favors towards idiocy instead of luck.

Oh what he wouldn't give to abandon his party completely and go off with a different adventure party. A party that was smart enough to make good on quests, and not stupid enough to cause him tons of problems all the time.

'Still... Darkness has massive boobs... it would be a shame not to be able to look at them.'

-With Naruto-

'Darkness really has massive boobs... Without that armor on, they really are something huge... I wonder who has the biggest nipples of these three... boob to nipple ratio-wise...' Naruto flipped the page in his book again. He was casually reading while his mind wandered around. His mind wandered, and it wandered to boobs. '... Does Darkness have small nipples for her big boobs, or big nipples to match them... I am like 99% sure Megumin has itty bitty ones... and Aqua... maybe big for her size, I can see that. She definitely has big areola for sure.' Naruto actually even glanced at Aqua's chest.

She didn't wear a bra, or she wasn't wearing one now, so he could see the general size of the puffs of her nipples. He was just guessing that Megumin had itty bitty nipples, since she had an almost completely flat chest. Then again, she was finished growing and had reached her adult height... so it was possible that she had bigger nips for her size.

Why was Naruto thinking about nipples?

He was kind of horny, the adventure book he was reading at the moment had it's very spicy moments. He felt Megumin staring at the book, and he didn't care if she read along, even for the hot moments.

"What... wow... PE-"

Megumin bit her tongue when Naruto shut her mouth for her, because she was about to shout out calling him a pervert. The last thing he needed was a ruined reputation. Now he had three silent allies at a table, silent for different reasons.

'Hmmmm... Darkness is a major Masochist... I might be able to get rid of my horny feelings using her perverted nature... or would that ruin the party if I did that?' Naruto wasn't sure if he could take advantage of Darkness and her masochism without causing friction with the party. If he could enjoy himself with her, and if she would enjoy it, then he didn't see much reason not to. "Darkness..."

"Yes?"

"Nevermind." Naruto continued to think about it. What would happen if he fucked her, and she got romantically interested in him. He couldn't just have emotionless sex with a party member and NOT expect her to want something more. Maybe if he played the part of a sadistic bastard, but as much as he was a sadist, he was also a masochist. More than any of that though, he was a romantic.

Could he do naughty things with a woman and not gain romantic feelings for her.

He thought about her feelings, but now he was thinking deep about his own personality. He looked into himself.

"Naruto?"

'My greatest fear is solitude... could I, who fears being alone, have sex with a woman and not fall for her?' Naruto did a deep dive into his own nature. He had completely stopped reading the book he was staring at. He had Megumin shaking his arm to try and get him to turn the next page in his book. '... and am I the kind of guy that could get off to sex without bonding with a woman first... am I even built to be able to get hard from emotionless sex?' Naruto felt Megumin turn the page in his book for him.

He was too busy analyzing himself.

Maybe.

Maybe he was the type of man who could have emotionless sex, but was he the type of man who could do that and not feel anything for a woman when it was done.

Then there came the consequences for sex.

What if he got a girl pregnant.

'I am an adventurer, and I am from another world... maybe I can use my knowledge of another world to really make bank. I'm a reckless person, I could easily see myself losing it and nutting inside of a woman in the heat of the moment... does this world even have protection?' Naruto hadn't seen a store sell any condoms, so he doubted they existed. Was there some kind of magical form of protection that he wasn't aware of yet.

Actually, would this world even do that?

With a Demon King trying to take over the world, and with human eating monsters, he was pretty sure that this world had population issues. So would having safe sex be seen as stupid in this world, because breeding needed to be done soon in life and as much as possible? He could understand rich assholes using protection, but in a world like this it might follow his world's logic from several hundreds years ago.

Have tons of kids, because most might not make it to adulthood to have kids of their own, and more kids meant having more hands to work at home. That also made him wonder about what the average age for a woman to have a child was in this world, since they had to have a much younger life expectancy considering they were at war with a demon king, and even women were expected to fight. Did women have babies in order to get out of fighting in the war, and if that wasn't the case, was there some kind of child care system in place?

So many questions.

Who had the biggest nipples?
Would fucking a party member ruin the party?
Was he a man capable of emotionless sex?
Where was this world in comparison to his own when it came to family logic?
Was it considered irresponsible to cum inside, or was it more irresponsible to NOT cum inside?
Did this world have a birth rate that exceeded the death rate, due to being at war?
Women became adventurers, so did villages have some kind of child care system in place?
This world had nobles and a monarchy, so what was the economical benefit to having kids younger?

"NARUTO!" Megumin smacked him on the side of the head.

"Yeah?"

"Turn the freaking page, I've been stuck and want to know what happens next." Megumin couldn't get the page out from under his thumb now without ripping the poke. Naruto turned the page without a word said.

'... now that I think about it, my parents have a child in this world too... so I have a sister out there somewhere. Is she an adventurer... is she a mother, am I an uncle?' Naruto couldn't help but think about his sister in this world, and what her life was like. He wasn't in any rush to go and meet her, though the sooner the better. '... Would she be pissed at me for knocking a girl up without marrying her... what is a woman's view on pregnancy in this world, the sooner the better, or wait for the right time kind of thing.'

...

'... How big is the average baby here, about the same as my world... smaller...? How many marshmallows could I shove in inside of a girl's vagina before I can't shove anymore in there.' Naruto had completely lost track of where his own mental conversation was going. Now he was just thinking random thoughts. '... big marshmallows. I think... I could fit... 7 in Megumin... maybe 5... and Darkness... 13... Aqua might look like that, but I'm pretty sure she is a virgin... so maybe 9... she might be deep though, so 15... ah who am I kidding, I wouldn't stop until I got to 20 with her and ruined her.' Naruto laughed to himself.

"What is so funny?" Darkness asked with a smile.

"Marshmallows."

"Huh?"

"I'm just wondering how many marshmallows you girls can fit in... your mouths." Naruto had gotten too relaxed and almost told the truth about what he was thinking. Thankfully he managed to catch himself in time.

Wait a second.

Did this world even have marshmallows!?

Could he invent marshmallows and make a ton of money from them, because it would be awesome if he could manage to do that. Actually, how much money could he make off inventing the condom... he would have to do more research to see if there was a market for that actually. He noticed that there was no concept of trains in this world, maybe he could make a steam engine that he learned in science class as a student.

Using the Steam Engine, he could become rich and powerful, earning a noble title of his own.

Could he defeat the Demon King by hitting him with a train, because that would be an absolutely awesome way to cap off this adventure, using something insane to kill the Demon King... at that point, he should invent a truck and hit the demon king with a truck.

Actually, would that cause the Demon King to get reincarnated in another world if he killed him with a truck?

The beauty of the male brain.

The ability to go from nipple sizes all the way to killing demons with trucks.

Now Naruto really wanted to invent a truck and hit the demon king with it.
