Building a Safe Zone with My Harem In The Post-Apocalyptic World Chapter 7: Teaching Sisters How To Kiss

"I’m here."

Gideon’s voice broke the quiet as he stepped out into view.

He wore only a bathrobe, loose and clearly borrowed from the changing room inside this gigantic bath, the kind of place that sohow also ca with a massage chair and a vending machine.

Sumr’s lips curved into a wide grin as she planted her hands on her waist. "I knew it, you really are special."

Her gaze flicked over him openly. "But seriously, why even bother with the robe? Show us what you’ve got."

"Sumr!" Freya gasped. "You’re insane!"

She turned quickly to Gideon, flustered. "P-Please don’t mind her. She’s just joking."

"I’m not joking, I’m being honest." She stepped closer, emphasizing the word as she spoke. "Won have ’needs’ too."

Her eyes lingered on him. "And n?" she added lightly. "n are even greedier when it cos to those needs."

Gideon instinctively stepped back. It was all happening too fast.

Sumr noticed imdiately. "Why are you backing away?" She lifted an eyebrow. "Don’t tell you’re a scaredy-cat too, like Freya?"

That stung more than he expected.

"Of course not, I’m just trying to be a gentleman. We literally t today."

"What? Don’t tell you’ve never hooked up before." She tilted her head, teasing. "Virgin boy?"

"Sumr, stop it! That’s inappropriate!" Freya protested, mortified, already apologizing again.

Gideon blinked.

It wasn’t like he had no experience. Even while sick, he’d gone to bars, talked, flirted, hooked up once in a while.

He just never let things go further. Getting close had felt pointless when he never knew how long he had left.

Still... being called out like that irritated him.

He exhaled, then took a step forward instead.

"Fine, if that’s what you think."

Sumr’s grin widened and turned cocky.

Gideon t her gaze, "Let’s at least be honest with each other."

"Lil sis, I’m going to show you what a kiss is actually supposed to feel like, not that weird video Mom showed about—"

She never got to finish.

Gideon was already in front of her, one hand cupping Sumr’s face as he kissed her deeply.

He sucked on her lips, nibbling lightly, giving her no ti to react. His other hand slid to her waist as her body staggered back, caught completely off guard by the sudden movent.

He pulled back just enough to look at her.

Sumr’s sun-kissed cheeks had turned red under his gaze. She stared at him for a second, then shut her eyes tightly.

That reaction made him smirk.

He leaned in again, licking her lips slowly.

"Co on," he murmured. "Open your mouth."

"W-Wait—!" Sumr shoved him lightly, her hands pressing against his chest. "It’s too sudden!"

But before she could say anything else, Gideon pulled her close again, locking her body against his.

She had nowhere to move as he kissed her once more, deeper this ti, his tongue slipping past her lips. Her breath hitched as he explored her mouth, leaving her gasping and unsteady.

Her chest was pressed firmly against him. He could feel those big boobs and how her nipple turned hard.

"Hnn..."

Sumr let out a muffled moan, saliva slipping from the corner of her mouth without her noticing.

Her body burned. There was a strange, embarrassing heat between her legs. Worse still, Freya was right there, watching everything.

She was completely overwheld.

Gideon finally pulled back, thin strings of saliva stretching briefly between them before breaking. Sumr’s legs felt weak, and he kept an arm around her waist to steady her.

She panted, glaring at him. "Ugh... you’re cheating. I wasn’t ready."

Gideon laughed softly. "You already lost to a virgin. How does that feel?"

"I’m not losing!"

Sumr snapped, shoving him away now that she could stand on her own. She stomped the water in frustration, refusing to admit how good it had felt.

Gideon only chuckled, fully aware she was lying.

His gaze shifted.

Freya stood frozen nearby, covering her eyes with her hands, though her fingers were spread far too wide to actually block anything. Her entire face was red.

"Do you want a kiss too, Freya?"

She gasped, shaking her head so fast it was almost painful. She couldn’t even form words.

Sumr giggled instead. "Just kiss her already. She wants it."

"Th-That’s not true!" Freya blurted out. "I just, ugh, I don’t know!"

She had never been exposed to anything like this. All she knew were her mother’s warnings: n were dangerous, don’t let them touch you, don’t get pregnant.

Getting pregnant in a post-apocalyptic world was terrifying.

Gideon stepped closer, gently taking her hands and lowering them from her face.

"Don’t worry," he said softly. "This will feel good."

He leaned down instinctively, closing the height difference between them. Freya was shorter than him, only about 158 centiters, and the closeness alone made her tense.

She shut her eyes tightly as his lips brushed against hers.

It was soft, warm, and slightly wet.

Her mind went blank. All she could feel was her heart pounding uncontrollably in her chest.

Gideon felt larger to her, his presence overwhelming, yet it did not feel dangerous. If anything, it felt protective.

That realization slowly eased her stiffness as he began to suck gently on her lips.

Tentatively, Freya tried to respond. She nibbled at his mouth clumsily, unsure of what she was doing.

Gideon laughed softly against her lips.

’God, she’s adorable,’ he thought, feeling how inexperienced and ssy her kiss was.

Freya had a different kind of beauty compared to her sister. Paler skin, larger eyes, a smaller face and softer lips, giving her an almost doll-like appearance.

His restraint slipped. "Open your mouth, Freya."

She obeyed without protest.

His tongue nudged against hers, and though she had no idea what to do, she instinctively brushed back.

Their kiss deepened into sothing clumsy and uncoordinated, tongues eting and separating as their breaths tangled together.

The taste was strange, sweet in a way she could not describe.

Freya’s breathing grew uneven. She grabbed onto his chest, needing the support to stay steady.

"Ahn... Gideon..."

He understood imdiately and pulled back.

Freya turned her face away, wiping her swollen lips with the back of her hand, completely embarrassed.

"How was it? Good, right?"

She nodded without looking at him.

Strangely, their mouths felt clean. Even their teeth looked healthy. It seed like they took better care of their oral health than their bodies.

"Hmph. Why are you only gentle with Freya?" Sumr crossed her arms, visibly annoyed.

Gideon shrugged. "You’re more experienced than her, so..."

"That makes no sense!"

He glanced at her with a grin. "Jealous?"

Sumr blinked, her face flushing all over again. "O-Of course not! Anyway, let’s just keep bathing!"

She turned away and subrged herself back into the water, blowing bubbles playfully like a child.

Gideon and Freya exchanged a look before quietly shaking their heads.

She was obviously just acting tough.
