The Spy's Price
The easiest way to force a woman to come along with you was to use a slave contract. But.
'Slave contracts aren't a panacea.'
When you bought a slave contract from the shop, the slave had to obey the master's orders unconditionally. But outside the scope of direct commands, unexpected actions were still possible. Information in ambiguous gray areas could leak out, and especially someone with advanced training like a ninja could even brainwash themselves into leaking information.
'A regular slave contract won't cut it.'
After deliberating, Kang Dohyun eventually turned his attention to the Special Slave Contract in the shop window and gave it more thought.
If a regular slave contract was a rare-grade document costing 500 Zombie Coins, the Special Slave Contract was a unique-grade document that cost 2,000 Zombie Coins. The Special Slave Contract didn't just make the slave obey the master's orders — it allowed you to add various additional constraints.
Dohyun steeled himself and purchased the Special Slave Contract, pulling it out.
"You want to live, right? Sign here."
Dohyun wrote his own name on the Special Slave Contract first, then handed it over and released her hands. Lee Chaerin, desperate to survive, wrote her name as well. But.
"You wrote your name, but it's not activating? Write your real name."
"This is my real name..."
Lee Chaerin had written what she believed was her real name, but it still didn't activate. Dohyun spoke again.
"Maybe... then write your Japanese name."
When she wrote her Japanese name, Sakura Mizuki, in Japanese on the signature line —
Sakura Mizuki has become Kang Dohyun's slave.
The Special Slave Contract activated.
"Hah... She's a spy down to her bones."
"....."
At those words, Lee Chaerin had nothing to say.
Dohyun used the Special Slave Contract's functions to impose constraint conditions on Lee Chaerin.
'First: suicide prohibited.'
He'd invested 2,000 coins in this slave girl. If she killed herself, the loss would be enormous.
And the second constraint:
'If she performs any action — or even thinks about performing any action — that could cause the master even slight harm, she will feel a headache. And that headache will stack.'
The moment he set the second constraint —
"Ah... ugh..."
Lee Chaerin clutched her head as pain surged through it.
'As I thought. Even right now, she's trying to find some way to extract information and send it back to Japan.'
She was certainly valuable, but she was a dangerous woman. If she ended up reduced to a mindless fool by the excruciating pain, so be it.
Finally, the third constraint:
'The only way to relieve the headache is by having sex with the master, or by experiencing sexual orgasm.'
He added the sex clause to mentally subjugate her.
Dohyun set the constraints and left Lee Chaerin alone for about an hour. During that time, she tried to think of other things, but the mounting headache tormented her.
"Ugh... ugh... ugh..."
As the headache stacked upon itself, she suffered pain so severe it felt like her skull would crack. And then she finally broke.
"M-Master, I'm going to die. P-Please... please save me."
She begged for her life. Lying in his sleeping bag, Dohyun replied.
"Get my dick hard, and put it inside your ass. The pain will go away."
At his words, Lee Chaerin reached out and touched Dohyun's cock. Fortunately, it hardened quickly. She climbed onto his body and inserted herself.
"Haaah......."
The headache that had been tormenting her vanished in an instant, replaced by a special sensation. The adrenaline that had been flooding her system from the pain made her body feel weightless — it was like being high on drugs.
In this heightened state, Dohyun began to thrust his hips.
'Squelch.'
"HAAAAAAAH!!!!"
With just one thrust, she reached climax, and her pussy gushed with nectar and urine.
"Wow, you really react well to this."
Dohyun enjoyed her response as he continued thrusting, and she couldn't even keep her mind on the pleasure.
That day, Dohyun repeated the cycle on the rooftop of the building — leaving Lee Chaerin alone until the headache built up, then having sex with her — all night long.
Kim Sooah spent two days alone in the tent without Dohyun.
'Something feels off.'
A man had been using her body, and now he'd been gone for two days. She felt a slight emptiness.
Still, when the sun rose, she washed up and prepared breakfast as usual, readying herself for Dohyun or Dohun's return.
At 9 AM, Dohyun returned to the tent.
"You're back."
He looked somewhat exhausted.
"Could you help me with something?"
"Of course, I should help you."
At her offer, Dohyun took Kim Sooah and went outside the Gijang County Office.
Dohyun loaded her onto the drone and flew up to the building's rooftop. On the roof, Lee Chaerin lay sprawled, fast asleep.
"...."
Seeing a naked woman lying there asleep, Kim Sooah was speechless. Dohyun explained.
"This woman is a spy. No need for sympathy."
"Ah... I understand."
There was something strangely trustworthy about Dohyun's words. It was because of his abilities and the favorability she'd gained from having sex with him, but Kim Sooah believed him immediately.
Lee Chaerin had spent two days in a cycle of suffering from headaches caused by her own thoughts, then screaming in pleasure during sex with Dohyun. She had eventually collapsed into a deep sleep from near-exhaustion.
Dohyun couldn't stay by Lee Chaerin's side constantly, so he entrusted her management to Kim Sooah.
"You'll be staying here for a while. Just take care of this woman."
The management method was very simple. Give Lee Chaerin, who was bound by the arms and legs, water and food. And —
"If she's in too much pain, you give her a handjob?"
"Yes."
Using the vibrator Dohyun had acquired, force her to reach orgasm.
"When I'm not around, if she's in pain for about an hour, just ram a dildo into her ass."
Kim Sooah nodded at Dohyun's instructions.
After entrusting Lee Chaerin to Kim Sooah, Dohyun went about other tasks. First —
'Thud! Thud! Thud!'
He used a desk from his inventory to block the stairs leading up to the rooftop. It was partly to guard against possible intruders, but also —
'I need to prevent Lee Chaerin from causing trouble too.'
Sorry, but Lee Chaerin harming Kim Sooah wasn't a big deal — but her causing other problems was.
He then dismantled the tent from the Gijang County Office and reinstalled it on the rooftop. And to his younger brother, he left a message:
And so began the unusual cohabitation of Dohyun, Kim Sooah, and Lee Chaerin.
During the day, while Dohyun went out hunting in the surrounding areas, Kim Sooah —
'Squelch, squelch, squish, squish, thump, thump!'
"Ahhk... ahhk... ah! Ahhhk!! Aaaah!! Ahhhrrr..."
When Lee Chaerin felt pain, Kim Sooah followed Dohyun's instructions and rammed a vibrator into her ass every hour to force her to orgasm.
At night, Dohyun returned from hunting and extracted information from Lee Chaerin.
"I-I'm a half-breed! My father is Japanese!"
"I've never been to Japan, but I received ninja training."
"I wanted to be recognized by my clan. So I decided to live as an information source."
"More than half of the people on the 12th floor of the department store were information sources like me!"
"My older brother is a Special Forces operative in the Self-Defense Forces. He's a gifted individual raised by the government!"
"I-I'll tell you everything! So please! Please ram my ass! Master! Please!!"
No matter how professionally trained she had been as an information source since childhood, the excruciating headache left her no choice but to spill everything.
And then, at some point —
'Thump, thump, splat!'
"Hahk, haaang! Haaang!!!"
Dohyun inserted himself, and Lee Chaerin, who had been suffering from tremendous pain, once again entered a drug-like state from the excessive adrenaline flooding her system.
"Hahk! M-Master, haaang! Th-Thank you! Haaaang!!!"
Lee Chaerin thanked Dohyun as she had sex with him. And gradually, she was becoming more and more subjugated to him.
Ten days after Dohun had been wandering around Dongbusan alone, he returned to the Gijang County Office.
He contacted his older brother.
'I'm at a building near the Gijang County Office. Let me know when you arrive.'
When he arrived near the building his brother had mentioned and sent a message, Dohyun came down on the drone.
"Let's go up."
"Yeah."
They flew up to the rooftop on the drone, and there were Kim Sooah and a woman he'd never seen before. But the moment that woman saw Dohyun —
"Master, please have sex with me again. Yes? Please. I'm begging you!"
She called him "Master" and begged him to have sex with her.
"Hey, I told you not to have weird thoughts. Stop thinking."
"But, I can't help it. Even if I don't want to think, I can't help it, okay? Please, Master, just keep your dick inside my ass!"
Because she had been brainwashed since childhood to live her entire life as an information source, Lee Chaerin found it even harder not to think thoughts that benefited Japan or not to leak information.
Lee Chaerin begged desperately, but Dohyun responded expressionlessly. She finally —
'Squelch, squelch.'
"Hahk... hah! Haaah..."
She found a dildo on her own and began ramming it into her ass, masturbating. But since reaching climax was difficult, she eventually clung to Dohyun again and begged.
"Master, please... I'm begging you! Yes? Please!"
When she cried and begged, Dohyun finally took off his pants. She climbed onto him on her own and inserted herself.
'Squelch.'
"Haa... good. So good."
Lee Chaerin began enjoying sex with her master, her face showing she had everything she wanted.
Dohun had arrived suddenly and witnessed a strange scene. Dohyun needed to explain, so he approached Kim Sooah, who was standing normally.
"What's going on?"
"Well, what's going on is..."
Kim Sooah explained to Dohun everything that had happened since Dohyun brought Lee Chaerin here.
"Hahk! Hah! Haaang! Master! So good! Haaaang!!"
On top of Dohyun's body, Lee Chaerin shook her hips fiercely on her own, screaming in pleasure.
