Building a Safe Zone with My Harem In The Post-Apocalyptic World-Chapter 33: [R18+] Which One Of Us Is Better?!

Gideon’s heart nearly jumped out of his chest when the door was suddenly thrown wide open. 𝗳𝐫𝚎𝗲𝚠𝚎𝗯𝕟𝐨𝘃𝚎𝗹.𝗰𝗼𝗺

But the moment he turned his head and saw who it was, he let out a long sigh of relief.

"YOU TRAITOR, FREYA!"

It was Summer.

Freya’s body stiffened instantly at the sound of her sister’s voice. She frowned and clung to Gideon even tighter, wrapping her arms around him as if she refused to let go.

"Nooo! I’m not done yet." She lifted her head, eyes glossy and pleading. "Kick her out, Gideon! It’s not fair, I wanted more!"

Summer glared as she shut the door behind her and marched closer.

"We agreed we would do it together next!"

"I don’t want to!" Freya shot back. "You had sex with Gideon the other night, just the two of you, so why can’t I?"

She turned her head away and buried her face against Gideon’s chest, refusing to look at Summer.

"Bu—but that was before we had an agreement!" Summer protested. "Now we do, so get off him!"

She tried to pull Freya away, but Freya slapped her hands aside faster than expected.

"No! That agreement isn’t fair. I want a new one!"

"You! Listen to your older sister, naughty brat!"

Summer snapped, twisting Freya’s ear hard enough to make her yelp.

That was when Gideon finally sighed and forcibly separated them.

"Alright. Both of you, calm down."

"NO!"

They shouted in unison, making him groan. This was exactly why he hated arguments between sisters. They were impossible once they started, stubborn to the core. Even his own sister had been like this.

"Or do you want your mother to hear this and drag both of you back to the bunker?"

That did it. Both of them froze instantly, then shook their heads at the same time.

"Good. Now calm down," Gideon said. "We’re making a new agreement. With me involved."

They glanced at each other, tension still sharp between them, before slowly nodding.

Gideon was dying to suggest a threesome every day and would probably enjoy it, but he knew both of them wanted him to themselves, at least for now. Neither of them wanted to share his attention yet.

"So," he continued, "Saturday and Sunday will be threesome days. On other days, you switch. If I’m with Freya today, tomorrow I’m with Summer."

The sisters didn’t respond immediately, clearly thinking it through.

Then, almost eerily in sync, they said, "Okay."

Most likely because the fear of their mother finding out was far stronger than their rivalry, the fight died down quickly, though the way they kept shooting resentful looks at each other made it clear the issue wasn’t fully settled.

"Well, since Summer is here anyway, why don’t we just have a threesome?"

Gideon grinned, stopping caring about the argument they probably had in their own head.

"But I wanted your cock inside me more! This is supposed to be my day!" Freya snapped, turning toward Summer. "You can get the leftovers."

Summer clenched her fists. "You, ugh!" She ran her hands through her hair in frustration before her lips curved into a sharp smile.

"You think Gideon’s fingers or mouth aren’t as good as his cock? I’ll prove you wrong."

She pulled off her shirt and shorts in one smooth motion, leaving nothing behind. Then she climbed onto the bed and pushed Gideon flat onto his back, positioning herself above his face.

The moment she lowered herself, his nose pressed against her labia, brushing her clit as her body shuddered. Heat bloomed through her, her juices already slipping down onto his face as she moaned softly.

"Ahh... hnn~ Gideon, eat my pussy like yesterday~"

She deliberately softened her voice, drawing it out just to provoke Freya.

Freya scowled, refusing to lose. She wrapped her hand around Gideon’s wet penis, stroking it slowly until it hardened again. She rocked her hips back and forth, letting his shaft glide against her slick folds as she whimpered.

"Hnn~ your cock feels so good even before it’s inside me, Gideon~"

Her fingers brushed the tip, coaxing out precum. Gideon hissed, and Freya smirked, her gaze locked on her sister.

"Is my pussy that good?" she teased. "It’s already this wet. Ahh~ I can’t wait to feel you inside as you ruin me."

Her words grew bolder as Gideon’s hips twitched upward, clearly desperate to thrust. Seeing that only made Freya grin wider.

Summer refused to be outdone. She leaned down, her lips closing around Gideon’s nipple, licking and biting until his body shivered. At the same time, she ground herself harder against his face.

"Come on, Gideon~ put your tongue inside me," she demanded softly, teeth tugging at his nipple as he finally obliged.

His tongue slid into her entrance, slow and deep. Summer gasped, her thighs trembling as pleasure shot through her.

"Ahh~ even your tongue can drive me crazy..."

That was enough.

Freya pushed forward and sank down in one smooth thrust, swallowing him completely. Her back arched as the thick shaft pressed straight into her G-spot, making her cry out.

"Ahnn~ Gideon... your cock keeps twitching inside me. You really love my pussy that much, don’t you?"

She tilted her head, tongue slipping out just to taunt Summer.

Summer laughed breathlessly, still riding his face. "Oh please. Gideon knows mine is better."

"No, mine!"

Their eyes locked, sparks flying as they shouted together, "Which one is better, Gideon?!"

Gideon, meanwhile, could only lie there, overwhelmed and satisfied. The way they fought for him, tried to outdo each other, was intoxicating.

’Like I can answer that right now,’ he thought.

His mouth was already occupied, Summer’s body trembling above him, especially every time she got more irritated at Freya. Her reactions were honest, impossible to fake.

He gripped her thighs and spread them wider, pulling her closer as his tongue moved deeper, slower, savoring her warmth and the taste of her juices.

’Yeah,’ he admitted silently and nodded, ’both of them are the best.’
