I laid my gaze on Nee-san, who closed her knees and looked down at the bed. She is still embarrassed to be seen naked, even though she left no attempt to seduce me during the two weeks we were away from everyone.

She was more nervous about being naked around the girls. ​​

"Alright, Nee-san, you are up next."

"Okay…" she muttered and exhaled slowly. Pushing her bouncy boobs forward as she got on her knees. "How?"

"Your choice."

The face-off, doggy, missionary, cowgirl, or whatever they were called, I was fine with them. Though the view of ass while pumping was undeniably charming.

Shizuka closed the distance and threw her arms around me. "Aa-kun, leave this to Nee-san."

Her sultry eyes lit up with a resolve I couldn't understand. What went through her head right now? I was blinking my eyes as she pushed me into a pillow against the headboard.

Yuriko straightened my legs and leaned on my shoulder. Shizuka moved her legs past me, placed a hand on my shoulder, and raised her body. Having my support, she looked back and grabbed hold of my treasure.

Some hit and miss here and there, she sank her hips, swallowing me up inside her. She cringed and clutched my shoulders, breathing heavily. She moved up and down, brushing her boobs in my face.

"Aa-kun... is blazing... my womb."

My feelings were quite the opposite. The layers of walls in her tight hole caressed me gently, igniting warmth in my core. Instinctively, I grasped the feeling. The girls probably felt the same when I patted them. So relaxing like slow classical music playing in my ears. Sex with her calmed me down instead of riling me up further. Like a single session with her could satisfy my huge libido. Her sex embraced all the qualities of Nao and upgraded it twice.

Is this how a blood-related sister felt?

(No…)

'Just kiddin'... or was I?'

Moaning my name now and then, Nee-san pushed her body to pleasure me. No man could ask for a better sister than her.

I leisurely moved my gaze to Saya vacantly staring at us. Noticing me, she jerked her head to the right and whistled. Nao was peeking from Saya's side, enviously watching Yuriko tracing circles on my chest and abs. I never put much thought into it before, but it looks like Nao awakened a muscle fetish; a fetish for my muscles to be precise. I will slaughter any man who tries to show off his body before my Nao-chan, be it gods or mortals.

No exception.

Nee-san struggled for air as more and more fluids trickled down to the bed. The sweat seeped of her pores, highlighting her creamy waist. Yet, she never slowed down, not even once, as if a ghost rushed her to make me cum.

I propped her asscheeks, prompting her to stop entirely with a frown.

"Aa-kun, I told you just relax."

I stroked her cheeks. "Why are you pushing yourself?"

She dodged my inquisitive gaze. "I am not."

I pinched her cheeks red. She pushed my hand and puffed her cheeks. "Aa-kun, bully."

"Don't lie."

"T-That's a bit complicated."

"Then simplify it for me."

She heaved a deep breath. "Nee-san… felt useless in the dungeon… I didn't notice the sneak attack until you were jumping around there… I can't help it. Your sister is useless, even the healings I do are worse than your potions. I am just luggage for everyone outside of this bedroom."

In a cracking voice, she spat out the uncertainties plaguing her heart. Protect me… Aimi didn't do anything in the dungeon because she knows I can handle anything this world throws my way. But this little healer wanted to protect me. Her sincere feelings made me smile.

I brushed the tears leaking from her eyes.

"Nao, do you agree with this?"

"Never," Nao denied firmly and thumped Shizuka's chest. "You are being an idiot…"

"Nao-chan," Shizuka moaned. "I am not an idiot."

"Why do you need to protect him? He can take care of himself just fine. He has a friggin' goddess on his back."

Shizuka clenched her teeth. "B-But I am his sister. I can't help but worry about his safety."

Nao curled her fist and lightly punched Shizuka. "Yes, you are his sister, his only family left. Still, you two share a different bond. A man and a woman. You have to learn to believe in him. Although he doesn't look like it, he is a cunning fox in man's clothing, smart and perverted beyond your dreams. Everything, I mean most of the things he does has a reason."

"He is cunning," Yuriko giggled. "Or I wouldn't have fallen for him."

"I am still here, you know? Stop stabbing my heart like that."

Saya chuckled and patted my back. "It's fine. I decided to accept your good and bad sides."

Why did the talk suddenly shift to me?

Nao smiled. "The main part is, you don't have to worry about fighting. We all are here for that. You just do what you are best at?"

Nee-chan stared into space. "What I am best at?"

"Looking after others' mental health. Remember the day we first met. You consoled me and Aiko. Without your and Asahi-kun's help, I wouldn't be here right now."

"Mental health…" Shizuka muttered absentmindedly and firmly nodded. A golden glow ignited in her eyes while her walls wrapped around my cock. "Got it. Healing my family's mental and physical wounds… I shall become the strongest healer."

Her resolve caught us off guard. That glow meant some sort of level up or a new skill.

(Her element leveled up straight to C.)

Damn nice. My Nee-san is sweet in both her appearance and demeanor.

Shizuka wiped her tears with her thumb and smiled. "Thank you, Nao-chan. You too Saya-chan. Yuriko-san, thank you too. You helped me decide that day. I could take this step because of your help."

Yuriko helped Nee-san?

"No worries, child. Now finish what you started."

The problem got solved without me saying anything. My waifus are indeed exceptional.

Shizuka gazed down and her determined expression crumbled. Red spread on her face, stretching to her entire skin. She tucked her chin, trying to look as small as possible, and moved her waist.

My cock hardened once again. Nee-san's vigorous endeavor coerced me into pumping her full. She trembled and sagged, using her arms for support.

She swiped a dip of my cum gushing out of her and put it between her lips.

"Ha… hah… Aa-kun's love is too much for me. Nao-chan… it's your turn."

"I-I will skip today."
