Broken Boundaries, Naked Desires
A slightly ragged breath echoed through the room.
"Hah, ah, haaa..."
It was because she was doing yoga.
During her period, she usually stayed as still as a corpse, so stretching out her body with yoga afterward was crucial. This was especially true this time, as she had spent the entire duration of her cycle asleep, leaving her muscles feeling stiffer than usual.
Wearing the athletic leggings she bought in the Desert City and the crop top she had worn under her clothes the day she first fell into the desert, she rolled around on the mat, diligently warming up.
"Mmmgh..."
She did the splits, opened up her shoulder blades, and worked hard to loosen her body using a self-taught, makeshift yoga routine.
She had no intention of risking her life on missions for the Adventurer's Guild anymore, but after three years of daily repetition, her body moved on instinct. On a personal level, she also absolutely loathed the feeling of her body being stiff right after her period.
It was just that she hated the aftermath of being curled up in a ball from hormonal fatigue, dragging on for days when she didn't want her body to be in that state. Simple as that.
"Phew, haaa..."
She continued to push herself, breaking a satisfying sweat, before finally sitting down on the damp yoga mat with her legs stretched out, panting. She tilted her head back, exhaling hot breaths.
She loved the strange pleasure that came from flushing out built-up fatigue through sweat and breath. It felt as though her body, which had been utterly defeated by something as trivial as a period, had finally reclaimed its freedom.
But then...
"Hmm..."
Perhaps it was because of the friction from her vigorous movements, but... her nipples were slightly erect.
When she wore tight crop tops, her breasts didn't sag, so she rarely bothered with a bra. Back when she went on guild missions, she would wear a sports bra or even chest wraps to bind them tightly so they wouldn't bounce around and get in the way... but today, she had only intended to do some light yoga. Naturally, she was braless... and her nipples were poking out, just a tiny, tiny bit.
"Did my libido seriously spike the second my period ended?"
Well, it made sense. Except for when she was dying of menstrual cramps, her body was used to a regular routine of ravishing women every other day to keep herself satisfied. Just as a cat can't resist a fish market and a sparrow can't pass by a granary, her sexual desire was bound to stir once her period was over. Doing yoga in a tight crop top without a bra was practically begging for her nipples to get stimulated.
"Sigh... I need to hurry up and seduce Echidna so she'll beg me to take her on her knees..."
With a prime target right in front of her, she was forcing herself to remain celibate just to build up a natural path to marrying into wealth. No wonder her body was growing restless.
As if to comfort her lonely, partnerless nipples, she lightly flicked one with her finger...
"Ah...?"
An involuntary moan slipped past her lips.
She wasn't even ovulating yet... but her body felt incredibly flushed, likely because she hadn't had a proper release in so long. While it seemed natural given how drastically her daily routine had changed, she couldn't help but wonder if there was any other reason for her to be this sensitive...
"Mmm..."
Well, how was she supposed to know? She had only lived as a woman for three years, and even before transforming into Roen, she had never known much about human anatomy. In a world where Lamias with snake lower halves existed, there was nothing weird about her erogenous zones being a little extra sensitive.
"Whatever, I don't care anymore...! Time for a shower."
Stretching one last time, she stood up, peeled off her sweaty leggings and crop top, and stepped into the bathroom. Showering after a good sweat washed away all her strange, lingering thoughts, leaving her feeling completely refreshed.
Meanwhile, Echidna...
"What should I do? How can I naturally get her pregnant?"
Her brain had rotted quite a bit. The reason was simple. While Roen was on her period, Echidna had read a book titled 108 Ways to Impregnate Humans. She had been deeply impressed by a devastatingly persuasive phrase in it: the 10-Month Menstruation Prevention Shot. This concept had drastically eroded any lingering guilt she felt about impregnating Roen.
"Penetration is out of the question. That would be forcing myself on her. This... this is a medical procedure to treat Roen's painful periods. Yes, that's exactly what it is."
As an Alpha Lamia, she naturally possessed an intense sex drive geared toward the preservation of her species. Although she claimed to suppress those desires, she had gradually stripped away her own self-imposed boundaries one by one. Consequently, the psychological barrier to performing sleeping rape on Roen had plummeted to zero. By now, it had become a daily habit, and she was sleep-raping Roen every single night without fail...
"Should I put my semen in a syringe? That way, I can deliver it straight to her uterus without damaging her hymen. After all, a hymen isn't a solid barrier; it already has tiny openings. If I inject the semen, I can get her pregnant while keeping her virginity intact. That means I won't be taking Roen's virginity by force, right? Yes, yes, exactly."
She babbled this utter nonsense with a completely straight, nonchalant face. It was clear proof that her beastly instincts were gradually overpowering her human reason. Echidna didn't even realize there was anything wrong with her train of thought. The rational mind of the Desert Sage, which had once kept her breeding instincts in check, had finally reached its absolute limit.
"For now, she has about a week before her fertile window opens. Until then, I'll just keep sucking on her nipples. It's my own little way of repaying her."
She claimed she was only going to inject her semen into Roen's uterus to cure her periods, but if this were truly a pure medical treatment, why would she feel the need to "repay" Roen? Deep down, Echidna knew that impregnating Roen was merely a way to satisfy her own breeding instincts. That was why she constantly muttered about repaying her by licking her nipples... but even her method of repayment was designed solely to satisfy her own lust. What an incredibly selfish creature.
As of today, it was safe to say that Echidna's reason had suffered a total defeat at the hands of her instincts.
"Hello, Roen!"
"Welcome back, Echidna-nim!"
"Did you just wash up? You smell wonderful."
"Really? I did a bit of exercise and took a quick shower. The soap smells amazing. It has a honey-like scent, and I think it lingered on my skin. Especially on my hands and face, I can really smell it."
Once she began surrendering to her instincts, Echidna felt much more relaxed around Roen. She could think about injecting semen into Roen's uterus without a single twitch of her facial muscles. Having succumbed to her primal nature and become warped, she no longer felt frustrated in Roen's presence. After all, once Roen fell asleep, she could satisfy her breeding desires to her heart's content. There was absolutely no need to rush.
"I'd like to examine your body a bit to find a way to prevent your periods. How about we do what we usually do, and you take some sleeping medicine?"
"Ah? Like general anesthesia?"
"Exactly."
Roen's nights belonged entirely to Echidna. There was no reason to be impatient.
"Sure, then... I'll leave it to you, Echidna-nim. I really want to be done with this awful period nonsense once and for all."
"Hehe, of course..."
Salivating, Echidna approached Roen, who was sitting on the bed. Deep down, a burning desire urged her to cup Roen's slender chin and steal a kiss... but ravishing the lips of a sleeping Roen would be more than enough.
Barely managing to lower her hand from Roen's chin to her shoulder, Echidna parted her jaws and sank her fangs back into the existing puncture marks on Roen's neck. The bite marks on Roen's neck showed no signs of healing, and as the sleeping poison surged into her body once again, her eyes quickly glazed over.
"Ah, already..."
A pure human's body was fragile. Far from developing a tolerance to the sleeping poison, Roen's body seemed to be growing increasingly sensitive to it. It was as if her body now fell asleep as a conditioned reflex the moment the fangs touched her skin...
"Mmm..."
Her trembling eyelids fluttered shut, and Roen drifted off into a deep slumber.
"Thank you for the meal...!"
The moment Echidna confirmed that Roen had lost consciousness, she laid her down on the bed and immediately pulled up the clothes covering her chest. Roen had intended to sleep wearing a pretty bra tonight, but unfortunately, it was time to say goodbye to it.
*Snap.*
Echidna slipped her hand behind Roen's back and effortlessly unhooked the bra. Grinning, she extended her tongue toward the pink peaks rising from the mounds of pale flesh. Her long, forked tongue began to expertly savor the nipples.
"Mnh..."
Just as she had felt earlier, her nipples were exceptionally sensitive today. Even though she had just fallen asleep, Roen reacted to the pleasure, her fingers curling as she tightly gripped the bedsheets. Watching Roen's reaction with immense satisfaction, Echidna thought...
"Well, I'll have to take off her panties anyway to inject the semen into her uterus. There's no harm in taking a little peek beforehand, right?"
Spouting more utter nonsense, she swiftly pulled down Roen's panties. With all guilt completely evaporated and her brain entirely consumed by breeding instincts, the beast was stretching its claws toward the arrogant human female who still foolishly believed she was the alpha.
