The Fruits of Her Training
"Hup!"
With a sharp grunt, Roen bolted upright in bed. Today. Absolutely. No matter what! She was not going to masturbate.
"Ah, damn it..."
When she went to the bathroom to check, a thick, white fluid was already leaking from her lower lips. As the white liquid trickled down the folds of her vagina and pooled at the entrance before dripping onto the wet bathroom tiles, a shudder ran through her body. Yet...
"This is so annoying..."
Absolutely. No matter what. She would not touch herself. Her body was going to keep acting up like this anyway as a side effect of the "contraceptive shot," so dragging things out wouldn't do her any favors. She was going to launch her counteroffensive to seize control from Echidna this very day.
She would start with foreplay, slowly stepping on the gas, and then steal her lips, making Echidna climax from a kiss alone.
"I'm a person of action, and the number of women I've seduced easily exceeds my ten fingers. Do you really think I'd lose to just one person? Me?"
Granted, there might have been two or three women she had let go because they were too much to handle, but every single active, dominant partner she had ever slept with had been thoroughly corrupted into a helpless submissive under her touch. That was a fact.
With her hand techniques and tongue work, anything was possible. She could turn even the most frigid, stone-faced woman into a drooling, desperate mess down below...
'Our Roen... you talk too much, don't you?'
Suddenly, the words Echidna had whispered flashed through her mind.
"Aaargh!"
She let out a frustrated shriek, but feeling suddenly embarrassed by her own outburst, she quickly turned on the shower.
"Just you wait. Even if you cry and beg beneath me, I won't stop..."
She muttered to herself again, then slapped her own lips with her hand. Smack.
If she kept this up, it would really look like she was just babbling nonsense out of fear of Echidna.
"How many years of experience do I have as a top?"
That was absurd. She was absolutely, definitely not doing this because she was afraid of kissing Echidna. Nor was she afraid of losing the battle for dominance and becoming a submissive bottom.
Victory was hers to begin with. She knew all too well that her only source of satisfaction came from being the one on top. What could possibly go wrong from just one more kiss?
"I'm not scared at all. Seriously, not even a little bit."
Repeating this self-reassurance like a mantra, she continued her shower. She planned to bring it up later in the evening.
Meanwhile, Echidna had begun a battle of her own. She had finally found a subject worthy of her research.
"Fundamentally, the reason living organisms excrete is to expel accumulated waste and unnecessary substances from the body. Excretion is simply the most basic biological system designed for that purpose."
Therefore, completely eliminating this function seemed impossible. That belonged to the domain of the gods, not a mere mortal creature like herself. Even if Echidna was a descendant of the Great Snake and an Alpha responsible for the preservation of her species, she could not trespass into the divine realm. However...
"If it's just a matter of fully resolving this process through urination alone..."
Wouldn't that be entirely possible?
If she could achieve that, Roen's anus could be developed into a literal 'back pussy.' It would remain perfectly clean, there would be no issue even if it stretched slightly, and it wouldn't matter if it could never return to its original shape. Well, Echidna would take care of any issues regarding tightness herself anyway.
In any case...
"A one-time dose will never be enough. Long-term administration is essential for a complete resolution. So, what if I design the recipe with long-term consumption in mind from the very start?"
Unlike short-term prescriptions that had to show immediate efficacy in a single dose or within ten uses, this approach would allow her to observe a body that gradually transformed over time, eventually altering its very constitution completely, even if there were no drastic changes at first.
"Of course, long-term consumption also increases the probability of side effects. If a side effect occurs, it could completely ruin Roen's body. Therefore, none of the substances in the medicine must conflict with one another to cause any adverse reactions..."
Echidna stopped mid-sentence and bolted upright. It was an old habit of hers that hadn't surfaced in a while. Whenever she hit a wall in her research, she would immediately move to find books containing relevant information.
And once she found the right book, she skimmed through the pages.
...Continuous ingestion of Kashupalmea or Aridain for over one year may result in severe physiological complications. Numerous clinical cases of organ failure have been documented...
"Hmm, so Kashupalmea and Aridain are out," Echidna muttered, closing the book. "It says long-term consumption of over a year can cause issues. There are quite a few documented cases, too..."
She would quickly find the relevant information, read it, and slide the book back into its slot. However, if her doubts weren't fully resolved or if another idea struck her even after putting the book away...
"Wait, doesn't that mean there are absolutely no issues as long as it's under a year? Both Kashupalmea and Aridain have exceptionally strong medicinal effects. If I set up a three-month administration cycle and make the other ingredients as potent as possible..."
She would keep searching until she voiced the exact answer she wanted. If she still felt something was lacking, she would shelve the book again and begin hunting for other related texts. Once Echidna was fully invested, there was no stopping her.
Since she had thoroughly enjoyed the Vongole pasta Roen made for her this morning, her energy was overflowing, allowing her to focus entirely on her research.
"Mmh, yes, yes. This is how you return a favor. What else could it be?"
Echidna felt absolutely no moral qualms about trying to strip Roen of a natural biological function like excretion without her consent. Whenever Roen climaxed from Echidna's training, she had developed a habit of stretching her legs, pointing her toes, and trembling. Such a precious little female deserved to have her back door thoroughly used as well. But keeping the back door clean was a hassle. So why not just remodel her rear passage into a canal dedicated entirely to my cock?
This utterly inhuman train of thought, combined with the sheer drive of the Desert Sage, somehow warped in her mind into: 'Look at me, being so incredibly considerate by conducting this research for Roen.'
Well, technically, it was a form of consideration. The real issue was whether Roen actually wanted this "consideration," but there was no way Echidna—who crawled into Roen's room every night to ravage her—would care about her victim's feelings. In all likelihood, Echidna would continue to act this way in the future.
"Hmm... is this all I can think of right now? But this formula will definitely trigger side effects... I should set up some animal testing first to get a better grasp..."
As Echidna formulated her first hypothesis and prepared to jump straight into experimentation—
"Echidna-nim...!"
"Ah, Roen..."
Echidna offered a somewhat lukewarm response to Roen, who had gone out of her way to visit the study. It couldn't be helped; it had been a very long time since Echidna had felt this burning academic passion as a scholar.
"What is it?"
"I was wondering if you had a moment?"
"Why?"
"I'm going to kiss you."
"Alright."
But research was research, and a kiss was a kiss.
"Where should we go? Do you want to do it here?"
"No, let's go to my room."
What kind of crazy woman would keep her nose buried in a pile of paper and ink when Roen was offering a kiss? At the very least, that woman wasn't Echidna. She immediately followed Roen back to her bedroom.
"Now, please sit here."
"Okay!"
Roen sat Echidna down on her bed, noting how exceptionally excited she seemed today. Echidna looked up at her with her hands politely folded in her lap. Roen cleared her throat with a soft cough before speaking.
"I'm going to make you cum completely with just a kiss, so don't go crying and begging me to stop. Got it?"
"Sure, sure."
Echidna gave a half-hearted reply, her shoulders twitching slightly. Her mind was clearly already consumed by the thought of the kiss. Women who wore their desires so openly on their sleeves were always the easiest to handle.
"Mmh-hmm..."
Humming a soft tune, Roen slowly approached Echidna. She swayed her hips slightly from side to side, walking as if she were gently wagging a non-existent tail. As she closed the distance between them...
"..."
Echidna closed her eyes, waiting for the kiss. But—
'Not yet.'
From the very beginning, this rematch was designed to make Echidna climax under Roen's absolute control. To build up the psychological tension, she bypassed Echidna's lips and reached for her hand instead.
She snatched one of the hands folded politely in Echidna's lap and pressed her lips to the back of it. Meanwhile, she used her other hand to apply gentle pressure directly over Echidna's pussy-covering scales.
'I'm going to attack you from above and below at the same time, Echidna. This isn't quite touching your pussy, but it isn't not touching it either. You can't even complain that this isn't a kiss, can you? After all, I only placed my hand on your pussy-covering scales to keep my balance.'
In any case, perhaps sensing something was amiss even with her eyes closed, Echidna's eyelids fluttered.
"Don't open your eyes. If you open them, I won't kiss you. Do you understand, Echidna?"
Seizing the moment, Roen leaned in close to Echidna's ear and demanded her absolute stillness. Like a true top. Like an alpha female. She deliberately dropped her usual polite honorifics, speaking in a commanding, casual tone. And then—
'Huh?'
She felt a strange, rapid vibration pulsing from deep within Echidna's pussy-covering scales...
Assuming it was nothing major, Roen focused back on the pre-kiss foreplay. It was probably just a brief shiver. She paid it no mind.
