The Obligatory Defense Battle (2)
Chub-bup, chubeu-bup.
“Haa…”
Nahyun lost all reason the moment she saw my cock, immediately diving in to suck it.
“Heu-beup…!”

All I had to do was enjoy the sloppy blowjob, occasionally looking down at her with cold eyes and giving the leash a sharp tug.
‘Who’s the one being punished here…’
As I received the oral service, I realized that since Yuna was first and Nahyun was second, the next turn would naturally be Jihyun’s.
‘It’ll be over soon, won’t it?’
My two rounds with Yuna took a little under an hour, so if I allotted another hour for Nahyun, the whole thing would be finished in two hours.
It actually felt more efficient than having all four of them at once.
Of course… I didn’t hate the situation. In fact, just a few days ago, this was exactly what I had been longing for while holed up in that hotel.
‘The tempo is a bit off, I suppose…’
Between my encounter with Min Serin and the three women who had been starving for over a week, our rhythms were just too different.
If that hadn’t happened with Serin, I might have been the one to pounce on them the moment I stepped through the door.
“Heu-beup.”
I gave the leash a light tug and looked down.
‘She really is beautiful, though…’
Sometimes I feel overwhelmed by the responsibility of taking care of these three women in every sense, but whenever I look at their faces and bodies, I realize how spoiled I am to even think that way.
What a blessing it is to have such beautiful women throwing themselves at me without hesitation.
‘Right, pull yourself together. It’s not like my body is struggling… though my mind is a bit exhausted…’
Clink.
“Heu-eut! M-Master?!”
When I yanked the leash hard, my cock, which had been filling Nahyun’s mouth, popped out.
A string of saliva connecting her lips to the glans stretched thin before dripping onto the floor.
I ran a hand through my hair and spoke.
“Get on the bed… and crawl like a dog…”
“Y-yes, Master!”
Nahyun scrambled onto the bed and got on all fours, not even bothering to wipe the saliva from her lips.
Just as I grabbed her hips with both hands to thrust inside, Nahyun turned her head slightly, giving me a seductive smile.

“Heu… can’t you hold it in either, Master? Do you want to fuck my pussy? Huh?”
“…”
She wiggled her hips, and my cock, which had been touching the entrance of her slit, lost its target and swung uselessly in the air.
Confused by the situation, I lifted my head to look at her.
“Hu-hurry… heu-eut! Say it, Master… You can’t stand it because you want to pound my pussy all night long, right?”
‘I almost forgot…’
I could tell exactly what she was thinking just by looking at her expression.
That slave bitch… no, Nahyun, was deliberately wiggling her hips and provoking me because she thought the level of corporal punishment was far too low and insufficient.
“Hoo… I guess… the punishment wasn’t enough yet.”
“Hurry up and say it. Mast—ku-heuk!”
Squeeze.
I yanked the leash hard, and she couldn’t finish her sentence, her body beginning to tremble violently.
“Heu-eo… M-Master, I can’t… breathe… heuk!”
Her throat was constricted, making it hard to even make a sound, and she began to beg me to loosen the leash.
Snap—
As expected, yanking the leash was the right answer.
“L-leash… please…!”
I lightly ignored her pleas, spread my free hand, and reached toward the ceiling.
“Heu-eo-heu…!”
Then, I brought my hand down, striking Nahyun’s buttocks.
Slap!
“Heo-o-o-ok!”

Pshhhhhh—
As she was struck, Nahyun let out a cry and sprayed her juices all over the bedsheets.
“It’s all soaked… This is where I sleep, what are you going to do about it…”
When I loosened the leash slightly, Nahyun finally caught her breath, her pussy dripping with fluid.
“M-Master, I’m sorry…! M-Mom said this might happen, so I prepared extra sheets…”
Slap.
“Heo-o-ot…! Heu-gok! O-ot!”
Sssss.
I struck her buttocks lightly once more to show I wouldn’t listen to excuses, and perhaps because she hadn’t expected this second spanking, she let out a pathetic moan and sprayed her juices once again.
“To cum just from getting your ass slapped by your younger brother… how starved are you, you pervert bitch.”
“Heu-ok… Master… I was wrong… please take a break… heu…”
‘She’s in a different class, alright.’
Min Serin has masochistic tendencies, but if she’s a beginner who just entered the world of perversion, Nahyun is a hardcore pervert who had been filling her head with all sorts of depraved fantasies while living a normal life with a straight face long before our first time.
She would barely be able to suppress her sexual desire even if I fucked her all night every two or three days, so it’s a wonder how she held out for over a week.
Perhaps her body and patience had already reached their limit, which is why she climaxed and sprayed her juices just from getting her ass slapped.
“Hoo…”
Nahyun was still lying prone, letting out low moans as if the aftershocks of her climax were still lingering deep within her.
“I haven’t even started yet, why are you lying there by yourself…”
“Yes?!”
I grabbed her buttocks with both hands and began rubbing my cock against her entrance.
Squish.
“Heo-euk! S-Sunghyun, no, I’m sorry! Master! Let’s rest for a moment…”
Squelch.
“Heu-eu-eu-eut! I’m cumming again, cumming! Master’s cock…! Ku-heuk!”
Slap.

“Nooo! Heu-eut…!”
“Fuck… you crazy…”
Strangely, I could feel her pussy tightening more and more every time I slapped her ass with my palm.
I don’t know if Nahyun intended it or if she was just acting on her female instincts, but it was enough to stimulate my sadistic urges.
The passionate, love-filled sex with Yuna is great, but sex with Nahyun is the kind that satisfies those filthy, dirty desires that everyone hides in their hearts—the kind that other sex can’t fill.
Seeing her buttocks trembling with red palm prints on them stirs up a sadistic urge I didn’t know I had, making me instinctively slap her ass again.
Slap.
Slap.
“Heu-ok! Heu-ot! Heu-o-ok!”
Nahyun, who had been begging for forgiveness at first, had now completely lost the ability to use human language, letting out only obscene moans.
I couldn’t see what kind of expression she was making, but it was obvious that she was drooling and snotting, wearing an adorable look on her face.
“Haa… you pervert bitch, tightening up every time I hit you…”
The hand holding the leash began to tremble. Nahyun, perhaps preparing for the pleasure that was about to come, began to take her final gasps.

“Heo-ok! Hu-eut! Heu-ot! Hu-eut!”
I put my weight into it and shoved my cock in to the very root.
I could feel the entrance of her womb touching the tip of my glans.
Perhaps it was the reward for slapping her ass so hard, but I could feel the entrance to her womb slightly open.
After taking a deep breath, I calmly aimed and scattered my seeds inside.
“Hoo! Fuck…!”
Splurt! Splurt!
“It’s… coming…! Ugh?! Heu-eut! Heu-ok?! Ku-heuk! Keuk…!”

Nahyun arched her back and neck, her entire body trembling like an aspen leaf.
Not only was she being ejaculated into while her womb entrance was crushed against my glans, but as the semen seeped into the slightly opened entrance, her brain seemed unable to fully process the pleasure, causing her to stop breathing and continue to shake.
“It’s… strange…! Ku-heuk…! Keuk!”
Sssss—
Leaving behind a short, final gasp, she sprayed her juices once more onto the already damp sheets.
“Ha…! I came so much…”
Even after I finished, Nahyun was still trembling all over.
Drip.
Only when I slowly pulled my cock out did she begin to breathe little by little.
“Heu! Hu-eu…!”
Pop!
“Heu-eu-eut! Hu-eu-eu-eut! S-s-s-s! Hu-eu-eut!”
And as my cock slipped out of her pussy, she began to gasp for air as if a blocked water pipe had finally been cleared.
“Whew… it’s winter, but it’s hot…”
Sweat was pouring off my body like rain.
When I opened the water bottle and took a big gulp, Nahyun raised her hand.
“Heu-eut… heu…”
Nahyun let out a moan, waving her trembling hand in the air as if she had something to say to me.
“Hm?”
When I brought my ear close to her face, she whispered softly.
“Heu… w-water… I’m thirsty…”
“Ah, right…”
I brought the bottle to her, but it didn’t seem like she could drink it on her own.
“Can’t be helped…”
I filled my mouth with water, kissed Nahyun, and let the water flow into her mouth.
“Heu-um…”
Nahyun must have been incredibly thirsty, as she gulped down the water I poured into her.
“Hu-ah… now I can live…”
“Then… shall we rest a bit?”
“Nooo… before the time is up… one more time…”
“Time? You set a time for that too…?”
I had wondered if they had set aside a specific amount of time for each of them since they had set an order, but it was true.
“Hoo…”
I wondered if Yuna telling me to go wash up was her way of cleaning the object she used for the next person.
Even though Nahyun’s stamina was completely drained from feeling too many climaxes in one session, she began to stagger as she climbed on top of me.
“Just one more time…”
“Yeah…”
I gave up on thinking.
I just started rubbing my cock against the entrance of Nahyun’s pussy as she lay prone on top of me.
***
Knock, knock.
Just as I was sitting on the edge of the bed drinking water after finishing my second round with Nahyun, someone knocked on the door.
‘Don’t tell me…’
“Hey, Oppa…”
“Yeah.”
As expected, the person who knocked was Jihyun.
“Are you… not done yet?”
“No, I’m done, but… the situation is a bit…”
“Hm? Situation?”
I got up from my seat and opened the door.
It seemed she had come to find me herself because Nahyun hadn’t come out even though her allotted time was up.
Perhaps the room was quite hot, because as I opened the door, the cold, fresh air of the living room rushed into the room, and the scent of the room, mixed with all sorts of pheromones, flowed out through the door.
“Ha-ang… what is that smell…”
Jihyun flinched, seemingly surprised by the scent that had suddenly permeated her nose, and began to rub her lower abdomen.
“Why is the situation…”
“See for yourself…”

“Heu… I can’t move…”
When I pointed to Nahyun, who was still trembling from the aftershocks on my bed, Jihyun shook her head and said.
“Oppa… go wash up. I’ll move Unni to her room…”
“Yeah…”
Jihyun licked her lips with her tongue as she looked at my limp cock.
A chill ran down my spine.
