RuneSky: Getting NTR'd in Another World With My Mom and Big Sisters

[NTR STORY: DO NOT READ IF YOU DON'T LIKE THAT SHIT. ALSO WHOEVER HAS A BETTER IDEA FOR A TITLE LET ME KNOW, THE CURRENT ONE SUCKS LOL] One month ago, Shotaro Koyanagi didn't expect to get magically teleported into the world of his favorite game, RuneSky Online! To him, it all happened so quickly. He was simply playing as usual, got blinded by a bright light from his monitor, and found himself in the fantastical town of Grimwalt, the starting town...alongside his mother and both his elder sisters? His family (except his father, who wasn't home at that time) somehow also followed him into the game. After a little bit of confusion, all four family members were met with a status screen, and each saw that they were blessed with a special ability. There was also a notice on the screen, saying that they must "defeat the demon king and his subordinates" to make it back to Japan. A classic scenario. Shotaro was excited at first. He decided it was best for them to do some adventuring as they find a way out. It's fun, and keeps their income stable. With their sheer strength, Shotaro and his overpowered family became the second strongest party in the Grimwalt Guild! To his happiness, his family also seemed to be exploring new areas, killing monsters, and helping out the common folk. Despite that, he can't help but feel like the dynamic between them was…starting to grow different. Especially as they meet some of the various NPC's in RuneSky.

Camping in The Denser Forest

As the Koyanagi family entered The GrimWalt hall, they were met with the same lively scene as usual. Lots of adventures in different parties under a massive hall made out of wood and cobblestone. Some people were planning out their next mission, while others were hanging out at the bar after a successful one. Of course, they also had finished a mission and are here to reap the rewards.

There was also another reason why they were here. Shotaro and his sisters followed their mother into the hall and walked to a massive man sitting alone at a table enjoying a beer. He saw the mature woman in white in the corner of his eye. He turned to them and raised a palm in greeting.

"Kids, here he is!" She introduced, "The Hero, Gunther!" 

"Hey. Nice to meet you all." Gunther smiled, holding his broadsword on his shoulder. "I've heard a lot about the Koyanagi party. Very strong bunch."

"Heh, of course we are." Rin chuckled.

"Rin! Be nice!" Fumiko shushed her sister, "He looks scary…and big!"

Gunther laughed, "Don't worry sweetheart, I ain't gonna hurt you. After all, we need all the strength to slay the Ice Drake." He then looked at Shotaro, expecting him to say something.

"Nice to meet you…man." Shotaro said awkwardly.

"Oh! I almost forgot about introductions." said Nari, "This is my son Shotaro, and these are my daughters. The one in black armor is Rin, and the one in the white robes is Fumiko. My name is Nari."

"Mhmm." Gunther murmured, "So what's the plan?"

Nari pulled out a map and laid it on the table. There was a red line drawn that started from Grimwalt and ended in the Northern Mountains. "We'll travel on Dracohorse, and it'll take around three days to get there. I've routed us so that we go through major towns to restock on equipment."

"Three days?!" Fumiko sighed.

"Come on Fumiko, it'll be fun!" Nari said, clasping her hands, "It's like a family road trip."

"What's a road?" asked Gunther.

"Ah..don't worry about it! Anyways, kids? let's get the reward for killing the troll and get on with the mission."

It was nighttime. Gunther and the Koyanagi party decided to camp out on the path to the Ice Dragon, right in the middle of the Denser Forest. They made it around a quarter of the way there after they left the Guild. The party had finished up a nice dinner and made a camp using Purified Firewood, to keep any lurking monsters away.

Shotaro squirmed in his little sleeping bag, having a little trouble dozing off. His sister, his mother, and Gunther were fast asleep. Even their dracohorses were fast asleep. All he could hear was the chirping of crickets and the rustle of the wind hitting the trees…but that was not entirely true.

*PLAP PLAP PLAP*

The sound of someone clapping started to fill the air. Shotaro immediately rose. Was it a thief? An assassin? He turned to find the direction of the sound, and honed in on the foliage of bushes nearby. To not alert the rest, he slowly crawled to it and peaked through a small hole between the branches.

On the other side was Rin, completely nude and on all fours. Behind her was Gunther, on his knees and also nude. He had a firm grip on Rin's waist and appeared to slam his thighs against her butt. The clapping sound came from their impact. Their bodies were lit by the moonlight, with their clothes and armor lying nearby. A chill rose up Shotaro's spine as he saw Gunther's massive, thick penis entering his big sister from behind.

"Yeah? You like that?" He moaned, "You ain't so tough now are ya?" He lifted his hand and slapped her ass cheek, leaving a red mark.

"Ahn~" Rin softly moaned with each thrust, "G-go slower please…" She immediately clenched as Gunther increased his speed, plowing deeper into her womb. Her eyes were glowing a bright pink, and it felt like she was inviting him in.

Shotaro still sat behind the bush, watching this whole ordeal. He wanted to jump out and stop it, but something held him back. Seeing Gunther's massive frame pleasuring the girl who protected him as a kid made him feel…small. It was wrong, but it made sense in a way. So, he sat back and simply watched. He could feel a tightness between his crotch, but didn't feel like it was time to play. 

Rin bent forward and stuck out her tongue. Gunther placed his large hand on her head as he pushed her head down, forcing his way deeper. After a few more thrusts, Gunther flashed a sinister smile. "Daddy's gonna give you a lil gift, okay?"

The tomboy smiled and closed her eyes, awaiting her treat. Gunther pushed into her as far as he could and held that position. Once he was set, he let go.

Rin blushed as Gunther's warm liquids seeped through her body, letting out a satisfied sigh. Shotaro saw Rin's belly grow a little bit with each pulse of Gunther's testicles. Gunther slowly pulled himself out of the cave, and Shotaro realized how far he went in. Six inches and counting. When he was out, white liquid seeped from Rin's behind.

Gunther stood up over her body and sighed."Release." He muttered. Rin's eyes quickly went back to her normal brown, and she quickly drifted off to a deep sleep. Shotaro also let go, albeit there was little from him. What was that "Release?" Was Gunther's mind control ability not a rumor? Rin would never let a guy in her like that. He slowly sat back, taking everything in.

Suddenly his eyes went wide. 

*SNAP!*

He had sat on a twig! Gunther took notice and sharply turned to his direction. Shotaro quickly scrambled to his sleeping bag. He put on the coceres and pretended to sleep, though he would soon find himself actually snoozing. The action must've taken all his energy away.

"Morning sleepyhead." 

Shotaro awoke to the sound of his big sister's voice. The groggy Shotaro opened his eyes to see that Rin was right above him! Rin took her hand and ruffled his hair.

"Rin?" He murmured. It soon dawned on him that he was laying on her lap, as if she were a pillow. Back in Japan, she'd often do this when he would be napping. He never understood why, but it was a nice gesture that he enjoyed.

"Mama! He's awake!" Fumiko yelled from near the campfire. Shotaro turned to see her and his mother cooking up some breakfast in a pot. 

Nari smiled, "Did you sleep well, Shotaro?" 

"Huh? I..oh yeah I did." Shotaro stuttered.

"Look who's awake." boomed the voice of a man behind them. Shotaro's eyes went wide. He quickly shot up from Rin's lap pillow to see Gunther standing above them in his armor. "It's almost noon, we gotta make a move. Grab some food and pack up. He said in a slightly scolding tone.

The scenes of yesterday night flashed in his head. The lap he had been lying him was home to another man just a few hours ago. He wanted to mention it, but decided against it. He shyly looked down and sighed. "O-Okay." 

"Agh, I dunno why I'm so sore." Rin yelled, stretching her arms. "I didn't do any training or anything yesterday."

"Take time to rest while the kid gets ready." said Gunther, "We need you in top form for the Ice Drake."

Rin scoffed. "Sheesh, you sound like our dad." Gunther chuckled in response.

Shotaro got up and started to pack his gear, all while Gunther watched him with his arms crossed. Shotaro felt the pressure of The Hero, telling him that he was the alpha here. Despite that, he ignored it and went on with his work. If anything, this confirmed Gunther's mind control powers. His Womanizer skill wasn't the only thing he had. Shotaro trembled. If Rin fell victim to his strength, what about his Mama and Fumiko? 

Soon, the party was all packed. They hopped on their dracohorses, and headed towards the Northern Mountains.
