The Mandatory Defense Battle (3)
The cold water pouring from the showerhead cools the heat radiating from my body and replenishes my depleted mental stamina.
“Ah... that feels good.”
My body, which is healthier than it has any right to be, hasn't even grown tired after ejaculating four times in two hours.
However, mental stamina is a different matter entirely. Even among Hunters who are considered monsters in terms of physical ability, many are weeded out because their mental fortitude cannot keep up with their physical prowess.
Staying up for a few nights or battling monsters is manageable, but continuous sex with three women is a different beast altogether.
‘How did people in the old days handle polygamy...?’
Looking at the current situation, it’s not even “polygamy”; it’s more like “polyandry.”
Literally, the initiative has completely shifted to my wives, and I feel like a husband who only enters the bedchamber based on their consensus.
‘But how did they decide the order?’
Looking at the sequence of Yuna, Nahyun, and Jihyun, it doesn’t seem like they chose through democratic methods like rock-paper-scissors or drawing straws.
And it’s unlikely that Yuna would have expressed her opinion to Nahyun and Jihyun that she would go first.
The most realistic guess is that Nahyun and Jihyun took a step back when the order was being decided.
I finished my quick cold shower, dried off with a towel, and walked back to the room.
Knowing that I could spend a quiet night once I finished with Jihyun gave me a boost of energy.
‘Since it’s the last one, I have to give it my all and make sure she’s satisfied.’
Creak—
As I opened the door, Jihyun was lying there under the covers, stripped of her clothes, just as I had expected.
“The sheets were too wet... so I laid down a thin blanket instead...”
“Oh... nice work.”
I had been worried about having to have sex on the bed that was already soaked from the previous rounds, so I was genuinely impressed by Jihyun’s thoughtfulness.
I climbed into bed and lay down next to her.
Jihyun turned her body to face me but didn’t say a word.

“Why... what’s wrong?”
As the silence continued, I was the first to speak.
“Honey... are you tired because we’ve already done it so much today?”
“Huh?”
“No... I could hear the sounds of you with Mom and my sister... it sounded so intense, I was worried you might be exhausted... If you’re tired, I can hold off for tonight.”
My heart ached.
When I first arrived home and the three of them hugged me, Jihyun had buried her face in my chest, breathing heavily as she inhaled my scent. Now, she was suppressing her own superhumanly accumulated sexual desire to be considerate of me.
What a thoughtful child she is.
At first, Jihyun was the most guarded, but now, her defenses have completely crumbled, and she wants to share everything with me.
She’s the type who gives everything once she opens her heart.
Before I even realized I was admiring her, my hand was already gently stroking her face.
“Honey...”
Jihyun closed her eyes, savoring my touch.
“Exhausted? Not at all... I could go all night.”
“Really?”
“Yeah, want me to show you?”
“Heh... no. I won’t be able to handle it...”
Jihyun smiled brightly, clearly pleased with my answer. We locked eyes, and without a word, we both leaned in, our lips meeting in a passionate kiss.
“Hnn...”
As we kissed, we naturally kicked the blanket to the floor, and I placed my fingers between her breasts.
“Haa-nn...”
My fingers slowly traced the valley of her breasts, circled her lower abdomen a few times, and finally reached her damp, sensitive clitoris.
Squelch.
“H-honey...!”
My fingers pushed past her labia and gently rubbed around her clitoris. Jihyun’s thighs trembled, and she let out a moan, whispering into my ear as if she couldn’t wait any longer.
“Hnn... Honey, do it now...”
“Yeah...”
Just as I spread her legs and moved to bring my cock to her entrance, Jihyun grabbed my wrist.
“I want to... while kissing you...”
“Huh...?”
“So... I want to be on top...”
“...”
Jihyun climbed out of bed and mounted me.
Our faces were so close they were almost touching, and I could feel the hot, wet breath of two horny people on my skin.
“Haa-nn!”
Jihyun lifted her hips, whining as she rubbed the head of my cock against her entrance.
It was adorable to see her actively trying to guide it in herself.
When I lifted my hips slightly to help her, Jihyun placed her hands on my shoulders and smiled.

“H-honey, just stay still... be comfortable. I’ll do it...”
“Okay.”
I relaxed my hips and sat back comfortably. Jihyun took a few deep breaths, and as if she had made up her mind, she lowered her hips, and my cock was swallowed whole into her depths.
Squelch.
“Hnnnng! Honey! Hnn-!”
“Hnn...!”
Jihyun gasped, pulling me into a hug, and gently stroked my cheek as she spoke.
“Honey... kiss me...”
Squish, squelch.
When I was with Yuna and Nahyun, their moans echoed throughout the room, but my session with Jihyun was quiet.
Her hot breath and moans were trapped by our lips, unable to escape, feeling as if they were flowing down my throat.

“Hnnn...! Hnn! Haa!”
Come to think of it, Jihyun loved kissing. After I started relations with the whole family, if Yuna was at work and Nahyun wasn’t home, Jihyun and I were often alone during the day.
When we were alone, we’d have sex all over the house, but even when we weren’t, Jihyun always demanded kisses from me.
Even when we were sitting on the couch watching TV, she’d kiss me, and even when we were lying in bed scrolling on our phones, she’d suddenly come over, climb on top of me, and kiss me.
With each passing day, Jihyun’s kissing skills improved by leaps and bounds.
Even now, she was performing a technique that would drive any man crazy—lightly grazing my front teeth with her tongue, pulling away slightly, biting my lower lip, and then kissing me again...
My body heated up from her stimulating kisses.
‘Come to think of it...’
I remembered discovering a weakness I hadn’t known about while having sex with Nahyun.
Wondering if Jihyun had one too, I began to shift the angle of my cock slightly, putting pressure on it every time I moved my hips.
Squish.
“Hnn...! Honey!”
I pressed the head of my cock against the same spot I had with Nahyun, but I only felt the ordinary vaginal wall.
Jihyun moaned, but she didn’t scream or drool like Nahyun did.
‘Is this not it...?’
I tilted my body slightly to the left, and as my cock slid in, I put strength into my hips and grazed the left side of her inner sanctum with the head of my cock.

“Hnn! Honey...! Hnn-!”
As the head of my cock brushed against the uneven part, Jihyun pulled her lips away, buried her face in my neck, and let out a moan.
‘This is it.’
I wrapped my arms around Jihyun’s waist and began to focus my attack on the newly discovered weak spot.
Squelch, squish.
“Honey! What is that spot! Hnn-! It’s weird! No! Hnn!”
My intuition was right; Jihyun’s eyes were rolling back into her head. She stuck out her tongue, and saliva began to flow from the corner of her mouth.
‘Should I try this on Yuna next time...?’
Come to think of it, Yuna’s entire body is a sensitive zone, so no matter how we have sex, she always reacts satisfactorily.
‘With Yuna... maybe I don’t need to look for one.’
“Honey! I love you! Hnn-! Hnn! Hnn!”
Jihyun seemed to have lost the energy to move her hips, so she handed all the initiative over to me and began to moan directly into my ear.
“Hnn...”
As her stimulating, lively moans struck my ears, the urge to ejaculate rushed in even faster.
I lowered my head and whispered into Jihyun’s ear.
“Jihyun... is it okay if I finish inside?”
It was a strange question, considering we usually had unprotected sex without a second thought. But this sudden question seemed to stimulate Jihyun even more, as she began to moan louder, drooling onto my shoulder.
“Hnn! Honey! Finish inside! I love you! Hnn...! Say, say something even dirtier, Honey...!”
‘So Jihyun has this kind of taste.’
As requested by my lovely younger sister, I whispered even filthier things into her ear.
“Hnn... if I finish now, so much will come out that you might get pregnant... is that okay...?”
“Hnn! I-it’s okay! Hnn! I, I’ll be the first...! I’ll have your baby...! Hnn!”
“Alright... then.”
I carefully grabbed her shoulders and pulled her away to see her face as she climaxed.
“Honey...?! No! I’m embarrassed! Hnn! Don’t look!”
Jihyun tried to turn her head, embarrassed by her own face—drooling, snot running, eyes rolled back—but I didn’t allow it.
“Haa...!”
Splurt, splurt, splurt.
I lifted my hips, gave a light kiss to the entrance of her womb, and ejaculated right then and there.

“Honey... ugh... ugh... hnn! Hnn! Hnn!”
Jihyun, not even given the chance to turn her head, faced me directly with her ruined expression as she reached her climax.
Even though it was my fifth time, my semen didn’t run dry, shooting out powerfully and striking her womb.
“Hnn! Hnn!”
I could feel Jihyun’s hand, resting on my stomach, trembling like crazy.
“Hnn...”
As I finished my fifth round and exhaled a breath of relief, Jihyun, seemingly reaching the end of her climax, let out a ragged breath and collapsed into my arms.
“Hnn...! Hnn! Honey...!”
“You did well...”
I stroked the back of her head, proud of Jihyun for moving her hips so hard on top of me.
“Heh... ugh...”
Squelch, pop.
After pulling out, I carefully held the exhausted Jihyun and laid her down on the bed.
Jihyun’s eyes were half-closed, sleepiness washing over her.
“Are you sleepy?”
“N-no... I’m going to do it one more time with you... I’m not going to sleep...”
Her struggle to stay awake was so cute that I stroked her cheek.
“There’s... a next turn, too...”
“Huh!?”
At Jihyun’s bombshell statement, the smile on my face vanished in an instant.
The heat that had only just subsided after 10 minutes of cold water flared up again, and a cold sweat trickled down my back.
“J-Jihyun, what did you say? Don’t tell me we’re going in circles...?”
Jihyun managed to open one eye with great difficulty, looked at my expression, smiled, and said,
“I’m just kidding...”
“Phew...”
I ran my hand through my hair, let out a sigh of relief, and looked down at Jihyun, who had been teasing me.
Jihyun was fast asleep, her eyes tightly shut, breathing softly.

‘She’s asleep... somehow, I’m a little annoyed.’
I brushed the bangs from Jihyun’s sleeping face once and covered her with the blanket.
“Don’t catch a cold.”
And thus, the first mandatory defense battle after my business trip came to a successful end.
