Home is where the Imouto is

Kamui was lying in his room, unused to the Hoshidoian style of sleeping. Ever since he decided to stay with his true family, he always thought about his other family in Nohr. They treated him like their actual family, but after the events that transpired, would he even go back to Nohr?

There was a tapping at the door. "Nii-sama?"

Kamui rose from the bed as Sakura made herself known by opening the door and entering the room. "Sakura. What is it?" Kamui asked in a concerned tone.

"I-I can't sleep..." The young girl looked at him with sad eyes. "I had a bad dream."

"A dream? What about?" Kamui tilted his head as his little sister walked towards him and sat near him.

"I-I was dreaming about people of H-Hoshido being killed by the N-Nohr army, a-and the s-soldiers came and took you away from me, a-and..." Sakura then burst into tears. "N-nii-sama..."

"Shhh..." Kamui wrapped his arms around Sakura, comforting her. "It'll be all right. No one will get hurt."

"B-b-but, nii-sama... You were apart of the Nohr Royal Family... and their army will be definitely trying to find you!" Sakura looked into Kamui's eyes with a tearful gaze. "W-What if...?"

"I won't leave you, Sakura. I promise." Kamui held his sister close to him, his heart racing like wild. Ever since he first saw her, she reminded him strongly of Elise, yet she was different in some ways.

"Nii-sama..." Sakura's voice whispered through his ears like a gentle breeze.

"Yes?"

"C-Can I sleep with you, tonight?" The blush on her face did not go unnoticed by Kamui.

"Of course."

"T-Thank you, Nii-sama." Sakura then noticed her brother state of dress. "N-N-Nii-sama, why are you... naked?" Her face became red as a tomato as she placed her hands on her face.

Kamui then realized he almost shown his birthday suit to his sister and quickly tried to cover himself. "W-Well, you see, it gets hot in here sometimes, and I'm not really used to the weather here..." He rambled, hoping she would buy it.

Suddenly, he felt hands surround his manhood and stroking it. "Wha-?! S-Sakura? W-What are you doing?!"

"So, this is what Nii-sama's thing looks like..." Sakura murmured softly as she gazed at her brother's now-erect penis. She had seen her brother in the nude before while he was bathing, but only on accident. Ever since that incident, she had dirty thoughts about him and occasionally masturbated to him, knowing it was wrong and indecent.

"S-Sakura... D-Don't..." Kamui breathed out, but the younger girl ignored him and proceed to place her lips on his manhood.

"Mmm..." The Hoshido princess pushed the cock inside her mouth and began to suck on it. "Mmmmhmmm..."

Kamui felt his mind run amok. If his older siblings saw this, gods know what they'd do to him. But at the same time, he felt excited at the fact that his little sister was giving him a blowjob. "Sakura... you..." The former Nohr prince placed his hands behind Sakura's head and pushed his cock into her mouth further, surprising the girl.

"Nee-sammuh?!" Sakura mumbled out as Kamui began fucking her mouth in a to-and-fro motion.

"Sakura, I want to you feel me... I want you to receive Nii-sama's love!" Kamui grunted out as he felt himself coming to a climax. "Here it comes!"

The younger Hoshido princess let out a cry as her mouth was flooded by her brother's seed. "Umph!" She felt her brother release her head and she pulled away from him, coughing and gasping.

"Are you all right?" Kamui gave a worried look to Sakura, who managed to get her senses back and nod at him.

"I'm fine, Nii-sama... I never thought it would feel so good..."

"Sakura..." Kamui looked at her. "...Do you want to feel even better?"

"Y-Yes, I want to receive Nii-sama's love even more!"

"Then let me see your body."

Sakura blushed, but she began to undress herself, dropping her night clothing onto the floor and showing her nude form to her big brother. "Is this okay, Nii-sama?"

"Yes... This is perfect..." Kamui leaned towards her and embraced her, causing her to blush. "You look beautiful."

"Nii-sama... you're being so lewd..." Sakura breathed out as she was brought towards her brother's lap.

"And so are you." Kamui slowly laid back on the bed as his sister hovered over his still-erect cock. "Come, sit down."

"Sit down?" Sakura blinked in confusion, then widened in realization as Kamui gently lowered her hips, the lips of her lower mouth kissing the tip of his penis. "A-ah! Nii-sama!"

"Relax, this won't hurt a bit!" Kamui felt his cock go inside his sister's secret garden as Sakura let out a cry of pain. "Sakura? Are you all right?"

"I-I'm fine...! It hurts, b-but it's starting to feel good...! Don't stop!"

Kamui nodded as he began to slowly pull in and out of her, letting her get used to the rhythm. He wanted her to have a good experience, after all.

"Nii-sama... faster. Go faster! I want your love in me!" Sakura cried out, her hips were now moving on their own and her hands were gripping on her brother's stomach.

"Sakura, I-I-I'm going to-Urgh!" Kamui grasped the sheets as he shot his seed into his sister's womb, both of them crying out as Sakura fell on top of Kamui's sweaty body. "Damn..."

"Nii-sama... I'm so close to you now... I feel your warmth..." The Hoshido princess panted heavily. "Don't ever leave me, Nii-sama..."

"I won't. I'll always be at your side, Sakura." Kamui smiled and placed a hand on his sister's head. His mind and body were already made up. The Nohr Royal Family may have raised him as their own, but to him, he was already home with his own family. And that would never change.
