A Snake's Mating Cycle
A darkroom... I wasn't sure if "darkroom" was the right word, but I was completely buried beneath a pitch-black blanket. Echidna's serpentine lower half easily exceeded three meters in length. Perhaps it was only natural for a blanket belonging to such a creature, but my own body—standing at just 170 centimeters, which was on the taller side for a human woman—was entirely swallowed up by the covers, without a single inch exposed to the outside world.
"Mmm, chup..."
To be honest, it felt quite nice at first. Since I had already abandoned all hopes of being the Top and reclaiming the initiative, what pride did I have left to stubbornly maintain a tense standoff with Echidna? I simply, quietly accepted the pleasure she offered. When my tongue was ensnared by hers, I let it tremble helplessly; when her saliva flowed into my mouth, I meekly swallowed it down. It was honestly delightful. Without me having to lift a finger, a pleasure far more intense than anything I had experienced since becoming a woman washed over me. It was as if she knew every nook and cranny of my body better than I did during masturbation, using her long tongue to press and stimulate the exact spots I craved, all while I remained completely passive. I didn't even have to say a single word. The psychological satisfaction accompanying the physical bliss was immense. Though she called me a Bottom, it was so comfortable and enjoyable that I almost felt like I was the master here, not Echidna.
But that smug confidence didn't even last a few minutes. Echidna's tail coiled tightly around my body, pinning me in place, and before I knew it, she began to target my pussy.
"Mph?!"
I let out a startled gasp at the sudden assault, but it was still bearable. Echidna's hand was kneading my buttocks from a slightly awkward angle, which didn't generate much pleasure anyway. I figured I just had to keep receiving the pleasure through my upper and lower mouths—my mouth-pussy and my actual pussy—until Echidna was satisfied...
"Mnh?"
Somehow, I realized that something far beyond my capacity to handle was beginning to build up. How much time had passed? I had already climaxed countless times, but about an hour after Echidna began her simultaneous assault on my mouth and pussy...
"Ah, ngh...!"
My lower abdomen trembled violently as something massive threatened to burst forth. I was terrified. It was the first time such an overwhelmingly intense sensation had surged through me. This was a level of pleasure that could never be achieved through self-pleasure alone. I was certain that an astronomical wave of ecstasy was about to crash over me all at once. My body had already come countless times, yet a tidal wave of pleasure equivalent to all of those climaxes combined was clearly on the horizon.
H-how do I...
How do I escape this? I tried wriggling my shoulders back and forth, but Echidna's serpentine coils were wrapped so tightly around me that I couldn't budge an inch. My eyes darted frantically left and right in the darkness, searching for a way out. And then...
I flinched.
Oh...
Whether my eyes had finally adjusted to the darkness or her eyes were naturally luminescent, I found myself staring directly into Echidna's glowing, slitted snake eyes. In that instant, I realized something was terribly wrong.
I can't get out...? She's not going to let me go...? No matter what I say? No, wait... My lips are pinned by hers anyway, so I can't even speak... Her tongue is deep inside my mouth...
I realized it, but it was already too late. I was already deep inside the serpent's maw. Though I had willingly walked into this trap, I never imagined she would take absolute control like this, stripping away every shred of my agency. The result was inevitable.
"Haaahhh... ♡"
With my tongue lassoed and bound by Echidna's, my mouth was forced wide open as I let out a vulgar, breathless gasp of climax. In the pitch-black darkness beneath the blanket, Echidna's faint, mocking chuckle brushed against my ear, but it evaporated from my mind in an instant. As I panted and let out lewd whimpers, I felt as though my very intellect was being drained out of my mouth along with my breath. I couldn't think at all. Instead...
"Slurp, chup, nh." "Mmm, chup..."
Echidna's long tongue and hot breath filled my mouth, replacing whatever sanity had just escaped me. It was a relief, in a way. Because Echidna was so intensely focused on the kiss, I was able to distract myself from what she was doing down below. Being attacked from both ends was honestly too cruel, and since escape was impossible, turning a blind eye to my lower half was the only way to preserve my sanity. But...
"Heeeyaaah?! Haaahn!"
Roughly once every hour, I climaxed spectacularly, soaking the mattress and blankets with a sticky mixture of love juice, saliva, and sweat. Because my body was pinned so tightly by Echidna, the physical thrashing of my orgasms was suppressed, but keeping that explosive energy bottled up had a strict limit of one hour. Once every hour, I had to violently spasm and shake to release all the tension her tail had pent up, gasping for the air I had been denied during our endless kiss and letting out loud, pathetic wails. Honestly, the only reason I survived this was because of my past as a high-ranking adventurer. If a normal human woman had been bred by Echidna like this, she would have suffocated or died of dehydration within the first hour. This was a feat only I could pull off.
S-still... it has to end soon, right...? Five, seven? No, six? Since I've already come six times... surely she'll stop soon...
Even so, there was a limit to how long I could endure. Locked in what was essentially a single, unchanging position, my lips felt like they were about to chap and tear, and my skin was bound to be covered in bruises. My clitoris was swollen so tight and hard that it showed no signs of subsiding. Honestly, at this point, it was starting to hurt, and tears were streaming down my face. I wanted to stop. I desperately wanted to stop coming. The pleasure had become terrifying. I was being forced to experience continuous ecstasy in the exact same posture for over half a day. I just wanted it to end, but...
"Huaaaah... ♡"
It wasn't ending. My mating session with Echidna showed no signs of stopping. I had heard that a snake's mating cycle could last for days, and it seemed she intended to do exactly that with me. Dumb, vacant whimpers leaked from my lips, and even the tears that had served as my silent plea for mercy finally ran dry. By the time the massive waves of climax, repeating roughly every hour, had crashed over me about fifteen times...
Ah...
Something warm and fluid surged down my throat. It seemed Echidna had injected nutrients into me through her fangs. Instantly, my thirst and hunger vanished. The risk of dying from dehydration was gone. I'm going to be trapped in this pleasurable hell for the rest of my life. The moment that thought crossed my mind, I felt a tiny, fragile thread of sanity snap inside me. After that, another eight massive waves of climax battered my senses.
To be completely honest, I couldn't remember every single moment of the twenty-three massive climaxes I had endured. But one thing was certain: from this moment on, until the mating cycle finally concluded, my memory would be a total blank. With a sudden drip, something hot burst from my nose, and after that, I truly remembered absolutely nothing.
"Ugh...?"
A dazed groan escaped my lips. The heavy, musky scent of female arousal—that distinct blend of love juice, sweat, and saliva that had filled the room—was completely gone. Instead, my body was enveloped in the fragrant aroma of bath salts.
"Ah..."
My brain refused to function properly. I remembered my nose bursting with blood before I completely blacked out, but everything after that was a total void. In fact, even my memories before that were hazy. I had no idea how much time had passed since I crawled under that blanket, nor did I know if it was morning or afternoon. And why on earth was I back in the grand bath again? As these disjointed thoughts swirled in my head...
"Ngh..."
Suddenly, an intense heat and pressure flared up in my breasts.
"Are you awake, Roen?"
"Echi... dna... ♡"
"I heard that if you perform Mammary Gland Development on a human woman like this, she can produce breast milk even without being pregnant. I really want to drink milk from your breasts, Roen. You don't mind if I develop them, do you?"
"Ahhn... ♡"
It was Echidna. Was this what they called a breast massage...? I only had a vague recollection of reading about such things on online forums back in my past life, so I wasn't entirely sure. But...
"B-by any chance..."
"By any chance, what?"
"Echidna-nim, do you have something like a Lactation Promoter among your venoms?"
"Well, who knows? Maybe I do."
"Ah..."
Judging by Echidna's playful response, a future where my breasts sprayed milk seemed entirely set in stone. Even if the manual development process failed to induce lactation, she would undoubtedly inject her own custom-brewed Lactation Promoter into my chest just to harvest fresh, sweet breast milk directly from the source.
"Haaah..."
I twitched under Echidna's expert touch, desperately trying to suppress the whimpers that kept leaking from my throat...
"Roen, after we're done bathing, let's take a trip to the Great City. I have a lot of things to buy, and I'll be lonely if I go alone, so you have to come with me."
"I-I understand, hngh..."
"You understand, right? Good."
Echidna casually decided our schedule after the bath without a second thought. Such was the life of a Bottom—absolutely nothing was ever up to me.
