4 Fun at the Onsen: Part 2

"Me! Me first this time!" Fumiko barked. She turned around to show her ass to Gunther and Shotaro in his lap. This was the first time Shotaro saw her sister like this. Just her bare cheeks and her brown hair.

"Kid, once you get to a higher level, you'll be able to do this too." Said Gunther as he took his member and stuck it into her gates of heaven.

"Ahn~ Let me do it this time~" Moaned Fumiko. She started to move her hips up and down, making Gunther enter deeper and deeper inside of her. This was so wrong for Shotaro, but why was he liking it?!

"Ah…Fumi-neee" Shotaro moaned. His mind was a blur. All he could think of was the experience in front of him. Shotaro moved his own waist back and forth, pretending that his penis was the one going in. Gunther felt him grinding on his neck, but let it be. Fumiko continued moaning as she sped up. She knew that Gunther was almost finished. 

"Fill me!" She cried as she pushed back all the way she could. Gunther shot out his sperm inside of her, flooding her womb. Shotaro eyed Gunther's member twitch as he shot his juices. Fumiko slowly backed out, leaving a trail of white, viscous liquid. "Ahh that was…amazing~"

Gunther then picked up the dazed Shotaro from his shoulders and plopped him on his lap. Both him and Fumiko eyed his small package, not even comparing to Gunther's size. Shotaro yelled as he unknowingly also let go, and a white arch shot from his tip. Fumiko cupped her hands to catch it, like a snowflake falling from the sky. She simply giggled at the sight. "You can't stop being cute, can you Shotaro~"

Shotaro climbed into the water and slowly made his way to Fumiko. "F-Fumi-nee…" Fumiko enveloped him in a hug and brushed his hair, calming him down. At this point, he was broken. There was nothing in his mind but his caring big sister.

Gunther then stood up from the water and put his hands on his hips. "So, Nari. Shall we play a bit?" 

"Of course~" Nari smiled as she did the same. She walked right up to Gunther"s arms.And pressed her body against his. Her large breasts were squished against his chiseled torso, with his giant arms holding her in place.

"You were always my favorite." He whispered.

"I know." Nari cooed. 

"Fumiko? Shotaro? How would you like a new daddy?" Gunther said, turning to the rest of the family in the water.

"I'd love a new Daddy!" Fumiko gleefully said. She grabbed Shotaro, who simply stared like a mannequin, and raised his hand too, "Shotaro said he wants one too!"

"Oh come here you!" Nari smiled and forced a kiss onto Gunther. Fumiko gasped in excitement. Gunther and Nari continued to trade french kisses, making a puckering noise every time their lips meet. 

The two stopped after what felt like an eternity, and looked each other in the eyes. "Shall I?" Gunther said, grabbing his penis, once again erect.

"Yes~" Nari took his rod into her own hands and inserted it into herself extremely slowly; as if she wanted to savor this moment. "Ahn~ I missed how this felt." She moaned.

Gunther then started to thrust his hips back and forth. For each push, Nari let out a mature moan. Shotaro watched as his mother's waist trembled with Gunthrr's might entering her. "Keep going!" Nari yelled.

"You like that?" Gunther responded.

"Y-yes!"

Gunther then turned to Shotaro with a dastardly smirk. "A weakling like you can't keep all these dames to himself!" He laughed, "They're better with me! They should join my party!"

"I wanna join Daddy's party!" Fumiko chimed in.

"W-We would be so much stronger that way~" moaned Nari.

Shotaro shook at their responses. He could not tell if this was the mind control or their actual thoughts. "I-"

"I think it's been decided." Gunther said, pushing all the way in and ejaculating inside Nari. White liquid started to drip from her crotch and trickled down her leg. Nari panted and moaned in exhaustion as Gunther carefully put her down near Fumiko. He then turned to Shotaro and Fumiko. "It's only the beginning, kid. Get ready."

Suddenly, the party heard a few footsteps approaching them from the entrance of the onsen. "Hey, Mama, Fumiko? I thought I—" It was Rin! Seeing the sight in front of her, she completely froze. "WHAT ARE YOU DOING WITH MY FAMILY?!" she yelled, sprinting it straight towards Gunther.

"Control." Gunther smirked. Rin instantly stopped right in front of Gunther. Her eyes turned bright pink, and slowly let herself fall into Gunther's arms. "Good girl."

Fumiko perked up, "Is Rin gonna join us?!"

"The rest of you go rest. I'm going to have a little fun with her myself."

"Ok~" giggled Nari, "Teach her well okay?" She and Fumiko then got up out of the water and headed towards the building. Shotaro watched as their bodies jiggled with each step.

"You too." Gunther demanded.

Shotaro simply nodded his head and followed his mother and sister. He was still in a trance-like state, he was not thinking straight. 

"By the way," Gunther added with a chuckle, "I turned off my mind control of you after you were on my shoulders." Shotar felt a chill down his spine. So that entire time he wasn't mind controlled? Was it him who just watched? Why did he partake in those actions? It was wrong, so wrong!

What if it was better for his family to join Gunther? His mom was right, they would be more powerful, and he wouldn't be a burden to them. He could also satisfy their womanly desires. Shotaro shook these thoughts away as he made his way back. "Tch." He scoffed.

He looked back to see that Gunther had started to make out with the mind controlled Rin. Maybe Gunther was right. It's only just beginning. 

Runesky was a cruel, but exciting world.
