Plee's Days of Becoming a Living Onahole (1)
One week before Plee was introduced to Lise.
At last, the chance for bloody retribution had come — retribution against Kim Dong-wook, who had forced his way into my memories of the man I held dear, defiled them, and had the gall to try to take that man's place. The liquid in the box that had bound and conditioned me could no longer withstand my awakened mana; it had been neutralized, and all that remained of the Kim Dong-wook before my eyes was the pathetic shell of a body.
I was rearranging the mana inside me, turning over how best to cook him, when his cock twitched and slowly began to rise. Before I knew it my gaze had locked onto that fully erect monstrous cock, and the mana I had so carefully rearranged collapsed, hollow, back into nothing.
Seeing me standing there vacant and spellbound, Kim Dong-wook seized the opening like a hyena. He hauled his trembling body upright, stroked his cock, and started closing in on me one step at a time.
...What am I doing? Snap out of it and rearrange the mana again... ngh... haah...❤
Tak.
Nngh... haah... nnghh... haaah...❤
Tak, tak.
Right... this has to be the liquid still left in my body... I need to purge it, quickly... nnghh... haaah❤
Tak-tak-tak-tak.
Ah... I want that cock buried in me all the way to the tip, just once... the smell alone is doing this to me... even earlier, when only the head went in... haah... if it sank in to the root, I'd probably... insane... I came a little just from imagining it...
Tak-tak-tak-tak-tak.
Why was I even resisting a cock like that...? Oh, right... to protect something precious... blonde? Black hair? Who was it again...!
Every time she fell under the spell of Kim Dong-wook's monstrous cock, Plee realized the memories of the man she treasured were growing a little fainter. With that thing now looming right in front of her, she dropped naked into a desperate dogeza, forehead to the floor, and began to declare her surrender.
"P-please!! I'll serve you as my Master!! From now on I'll serve your monstrous cock as a living onahole... so please, just don't take the memory and the name of my precious black-haired man away from me."
At my declaration of defeat as a beaten female, Kim Dong-wook stroked his chin and sank into thought, and I meant to use that gap to purge the liquid's accumulated effects from my body.
In a flash Plee had rearranged her mana — and then a thought struck her.
I... I already made that humiliating surrender, and i-if I really wanted to, I could deal with him anytime... maybe just once, just this once, I should experience it... right. Information and experience are essential virtues of a great mage...
Swallowing dryly before she could stop herself, eyes fixed on the monstrous erection dangling in front of her, Plee let the rearranged mana collapse back into nothing.
"Hmm... what am I supposed to do with this..."
For nearly an hour, Kim Dong-wook left me like that — naked, forehead planted on the floor in dogeza. Humiliation, shame, and killing intent toward him only thickened as the time crawled by, but whenever they did, he tapped the top of my head with his cock and went on talking.
"I'm not sure it's right to use an onahole who rebelled against her master and even showed killing intent... but I'm a merciful Master, so I'll forgive you just this once. A special exception."
"......"
"Oh? I even went out of my way to forgive you and said I'd use you, and I don't get an answer?"
"Th-thank you, Master."
At last, after that long deliberation, I wrung from him his permission — if it could even be called that — to use me, and already my womb was pounding, burning hot. In the same breath he hauled me to my feet, hooked one of my legs up over his chest, and dragged his cock back and forth through my spread pussy, teasing me without mercy.
Ooh... this is dangerous❤
All he was doing was scraping the swell of my pussy — just the head of his cock, back and forth — and yet that much stimulation alone was already burning my reason white.
"M-Master, just a moment, let's res— ooohk, oooh❤"
I had meant to ask him for a brief rest, but Kim Dong-wook didn't wait. He drove his cock into my pussy all the way to the root. In an instant the head of that monstrous thing kissed the mouth of my womb as if speaking to it, and my womb, delighted, opened to welcome him in.
N-no, nngh❤
Unable to last even a minute, Plee hit climax after climax as her reason began to melt, and unwilling to let Kim Dong-wook see her face, she ducked her head into his chest and hid it. At the sight of her like that he smiled as if she were something lovely, then opened his mouth and whispered against her earlobe.
"So. What was that man's name again?"
".....Don't."
"Keep that up and I'll pull out. You don't need the cock?"
The threat landed together with his hips stopping dead. With his cock still buried inside her the climax cut off, and an itchy, unbearable hunger crashed down over Plee.

"M-Master... please don't pull out... and please, at least don't defile my precious memories..."
Plee, who had kept her head down so he wouldn't see, lifted it — and her bare face was already streaked with tears from climax and pleasure. Kim Dong-wook had been angry at her refusing his brainwashing yet again, but whatever he saw in the expression and the face she showed him next seemed to satisfy him. He began driving his hips hard, exactly as she had begged.
"This... this feels too good, Master❤"
Plap. Plap. Plap.
Every time his cock slid through the slick gushing from Plee's pussy, the obscene friction filled the dungeon, and at some point — her expression melted completely — she began reporting even her climaxes to him.
"Plee's pussy is full of Master's cock... haht❤ Plee's pussy just came again. Master's cock already made me come for the seventh time❤"
As if she had given up hiding her feelings and her face and begun spilling herself out exactly as she was, the urge to come hit Kim Dong-wook as well. He exhaled and came deep inside her. Flooded with the heat of his semen, Plee passed out mid-climax with her tongue hanging out, and Kim Dong-wook, watching her like that, collapsed beside her and started to drift off.
"Ah... I shouldn't fall asleep yet..."
Plee was the first to wake.
The beastlike mating with Kim Dong-wook came back to her all at once. Shame and embarrassment rushed in; she covered her reddened face with both hands, then quietly began to study him where he lay beside her, back turned, still asleep.
"Well... I've already experienced it, so..."
As she stared at Kim Dong-wook, a black sphere was taking shape above her fist.
"Shlrp, shlrrp, shlrp, shlrp, shllrrp❤"
To the lewd, vulgar sound of something being sucked — and the warmth, the soft, squishy tongue against his cock — Kim Dong-wook's eyes slowly opened. Meeting them, Plee greeted him without ever letting the cock filling her mouth slip free.
"Mashter, shlrp, you're awake? Shlrrp❤"
Whether she expected praise for serving his cock of her own accord, or whether simply having it in her mouth was enough to flood her with rapture, her voice was giddy. And what Kim Dong-wook did next far exceeded anything she had expected.
"Khek— khk, khk— khek— M-Master, wai— khk khk— just a moment. Khek—"
He seized her head in both hands — the head of the woman with his cock in her mouth — and pressed down hard, shoving it deep into her throat. Tears welled in her eyes, and every time the head stabbed at her vocal cords she made a sound close to retching. The one mercy was that Kim Dong-wook himself wasn't used to stimulation like this. The urge to come rushed in quickly, and he poured his semen out with his cock still buried in her throat.
Only after he had finished, and wrung out every last drop, did he let go of her head. Freed from his cock, Plee gasped for breath with tears streaming down her face.
"Hah... just try using my cock again without my permission."
Only then, at his words, did Plee realize what she had done wrong. She opened her mouth with tears still brimming.
"I-I'm sorry, Master... from now on I won't use your cock without your permission."
Of course, she had no idea that the real reason Kim Dong-wook was angry — and the purpose behind what he had done — was something else entirely.
"Well... I've already experienced it, so..."
At the rustle, and at the chill in Plee's voice, Kim Dong-wook was already awake. He was only playing dead. The threatening shift of mana he could feel from her presence alone was enough to keep him lying there, still as a corpse.
Of all moments to fall asleep right then... Should I get up even now and beg her to spare me? Right — they say sharing a body forges a bond...
He knew perfectly well that begging pitifully for his life wouldn't save it. So he thought, and thought again. And at last, one method occurred to him.
"Nngh..."
Murmuring as if in sleep, he shifted until his cock pointed at Plee, then — with careful control of that half-erect thing — began to squirm and pant like a beast in heat, tempting her. It worked. The threatening mana crushing down on him vanished in an instant.
"....J-just one more time. I'll experience it once more, and then I'll finish him..."
At Plee's endless one-more-round, Kim Dong-wook felt the sheer joy of having survived. Warmth closed around his cock, and feeling it, he quickly began drawing up a plan to corrupt her into a masochistic female.
