#19 Rear Hole Development (4)
As soon as Yuchan arrived home, he spotted Seohyun passed out with a vibe buried in her ass and Nayae sleeping angelically beside her. He hadn't given any detailed orders on how to train her, but Nayae seemed to have done a decent job. It wasn't easy to make a woman climax until she blacked out.
Yuchan approached Seohyun, checked her breathing by holding a hand under her nose, and then yanked out the vibe, which twitched faintly back and forth with every breath she took. Her body jerked with a hiccup-like gag, and her asshole—once clenched tight—was now swollen and gaping from all the stimulation. After the long-embedded vibe was removed, it spasmed for a moment before settling back into its pretty shape. It wasn't ruined completely. Nayae had instilled excessive jealousy toward her, but she'd shown some mercy as a friend. That was fortunate.
"...Welcome back?"
Nayae woke from her light nap at the commotion, spotted Yuchan, and beamed as she threw herself at him.
"Yeah, did you have fun too, Nayae?"
"Yes, it was a great time. Please let me do it again sometime!"
Her judgment was still fuzzy from just waking up, leading to this reckless attitude. Yuchan grabbed Nayae's forehead as she clung to him and pushed her away, issuing a command. She pouted, a bit hurt by his cold demeanor despite their reunion after so long.
"I need to talk to Seohyun alone, so wait outside for a bit, Nayae."
"Okay."
She wasn't thrilled about leaving them alone, but it wasn't enough to defy her teacher's order. She wanted to tell him all about how she'd tormented and trained Seohyun. With a pang of regret, Nayae was gently nudged back and slipped out, quietly closing the door.
He first undid the leather straps binding Seohyun's arms. The flesh where they'd dug in from all her writhing was slightly bruised. Glancing at the various sex toys scattered on the bed with her, he could guess the treatment she'd endured—they were all slick with lube, as if every one had been used. Even brief insertions and withdrawals wouldn't consume that much unless she was an average woman reaching climax after climax. And they all looked soaked from prolonged use.
Yuchan smacked her plump ass cheek like drumming a large drum. It clung stickily to his palm—prime flesh he could spank endlessly.
"Mmph... hng... s-stop... I don't wanna go..."
Seohyun jolted awake as if resuscitated, frantically scanning her surroundings and mumbling incoherently. Spotting Yuchan, she shrieked in a sharp voice.
"Wh-what?!"
"Good evening."
"You... you fucking bastard! You scum! How could you do something like this?!"
Realizing her bindings were loose, she lunged to strangle him. Her bare tits bounced wildly, but she was full of energy. Yuchan caught her wrists, twisted lightly, and slammed her back onto the bed. From the look of her, Nayae had tormented her plenty, yet she blamed it all on him. A girl's pure heart could be this blindly devoted. Even the oblivious Yuchan was slightly impressed.
"Let go! I said let go!"
"Calm down a bit."
"You're... too much... hng... how could you... how..."
Whether from despair at his unyielding strength no matter how she thrashed, or an explosion of pent-up sorrow, Seohyun began sobbing loudly. Her hatred and rage had twisted into pure grievance amid the repeated defeats.
"Don't you wonder how sweet, innocent Nayae could do something like that to you?"
Just as Nayae's jealousy toward Seohyun had been fine prey, Seohyun's trust in Nayae was mere daily bread for Yuchan.
"I'll show you right now."
Yuchan pulled out his smartphone with one hand and started playing the footage of Nayae's training for her.
As usual, Yuchan had broken into the house and raped Nayae while she slept, without permission. He'd drugged her into unconsciousness with suspicious pills and treated her like a fuckdoll. He'd forcibly enlarged her clit and injected unknown drugs into her womb. Once he'd brought the terrified, trembling girl into his home, he'd forced her to film a vulgar self-introduction video. He'd pissed on her face to humiliate her and pierced her nipples. Terrified, Nayae had desperately plastered on a fawning smile, shaking her ass to stay in his good graces. To earn a single meal—dog food worse than scraps—she had to grovel on all fours and perform every filthy act he demanded. The once noble and pure Nayae crumbled under fear, day by day. Her psyche creaked audibly, fraying with each passing day. He kept her awake for three days and nights, forcing her to write and recite essays praising him and degrading herself in a half-dreaming haze. When she suffered in delirium, he'd grab her arm and jab a syringe to force her awake. A demonic ten-day regimen of training and brainwashing.
Seohyun watched the video, tears streaming endlessly. Seeing Nayae defiled by Yuchan, ultimately denying her former self—it tore at her heart just to witness.
"You're a demon... a demon in human skin. How could you do that?!"
As expected, Yuchan was the one who'd broken Nayae. Crimson hatred surged alongside inexplicable revulsion that churned her guts. How could anyone treat a clueless twenty-year-old girl like this?
"Nayae finally submitted. She believes true happiness lies in serving me and devoting herself fully. Even her torturing you today was all at my command."
"You fucking piece of shit... human trash..."
From Seohyun, spilling tears and venomous hatred, Yuchan sensed another emotion. Faint and overshadowed by the stark hatred, but unmistakable: relief. Nayae was the good girl Seohyun believed her to be. Her tormenting Seohyun like this was all Yuchan's fault—that conviction had solidified.
"Don't talk like that. I'm genuinely regretful, you know."
"Regretful? Trash like you?"
"Regretting why I didn't fuck her sooner."
"You bastard...!!!"
Overcome with fury, Seohyun's face flushed beet red. She was fun to tease. Unlike the fearfully trembling Nayae, her defiant stance to the end appealed to him. With time and brainwashing like Nayae's, he could turn her into an obedient little cat in days. But Yuchan didn't always claim women the same way. Nayae's case had gotten messy, forcing a rushed approach. Brainwashing had the drawback of killing off personality and traits. There was charm in a girl who eagerly spread her legs, but plenty of flavor too in one who resisted, wept, and thrashed wildly even as his cock pounded her. Seohyun had excellent potential. She'd struggle in his grasp to the end, screaming in rage. No resignation—just the fresh thrill of raping her anew each time. What a perfect toy. Plus, she was the ideal bridge to corrupt Yujin.
"Anyway, the point is simple. Obey me if you want to protect Nayae. You can't report me anyway. If you do, it'll drag not just me, but you and Nayae into court too."
"You think I'll let everything go your way? Even if it ruins me socially, I'll make you pay!"
"Nayae will confess it was all her doing. She's completely hooked on me—no way she'd give unfavorable testimony. Sure, I'll take some blame. But how long in prison? Three years? Five?"
"So what are you getting at?"
"I've got way more money than you think. Assembling top lawyers for a suspended sentence isn't far-fetched."
All Yuchan had directly done was leave Nayae with Seohyun and lend them the house. No evidence of threats, and with Nayae—the victim turned perpetrator—actively confessing solo guilt, Seohyun's claims of his orchestration would lose all weight.
"No matter how you fight, you can't hurt me much. But I can drag you and Nayae to hell if I want."
Realizing this, the pure fury in Seohyun's eyes dimmed. Her expression shifted to cunning calculation, trying to guess his demands.
"What horrible thing should I do to Nayae, who reveres you without knowing you've ruined her?"
Revealing Nayae as the pure victim was for the negotiation ahead. Pure threats to Seohyun's safety might lead to a police report someday. Beneath her tough exterior, Seohyun was affectionate—harboring feelings for Nayae bordering on love. So she'd submit to Yuchan's toying not just for herself, but for Nayae too.
"Shall I upload all those videos Nayae filmed of you side-by-side on a site? Or set her up as a hooker, funneling the cash to me. A girl her caliber could make a mil a month after three tricks easy."
"....."
Before his malice, even calling him demonic felt trite. Seohyun could only listen, speechless, to his brutal future blueprint.
"Or overdose her on drugs and kick her out for good. As you've seen, she can't live without Teacher. OD'ing in pleasure ignorance could be mercy. It's all up to you."
Seohyun knew it. This man had no guilt. If he said he'd do it, he would.
"...What do you want..."
Finally, she raised the white flag. Her heart hadn't surrendered, but her mind understood. Defying him was impossible—for Nayae's sake, she had to obey here.
"Become my pet too. The more you take my seed, the less burden on Nayae."
Of course, even if Seohyun sacrificed for Nayae, Nayae would just resent it. Seohyun saw it as protection; to Nayae, it was stealing Teacher's love.
"Fine. Then you won't torment Nayae anymore?"
"Depends on your attitude from now on—it'll get better than this."
"Ugh..."
No firm promise even with her pledge. His vague reply offered no contract or trust. Yet Seohyun had no other choice. For herself and Nayae, this was the lesser evil.
"Then let's start with some etiquette training. No
