Case 35: By the rule of carnality. (R-18)

Creatures were designed to follow their desires.

If there were no desires, there would be no existence either. In this universe of moving quarks and particles, if a living being failed to develop even the tiniest will to accomplish anything, it would be no different than the other mindless, inorganic matter floating around in space.

For most creatures, the will to live came first. Then, perhaps the will to reproduce.

I had no idea who engineered the third gender of females with male genitalia, but they had to have gone overboard in some aspects, be it for the better or worse.

The most recognizable effect of this was the fact that people like Rachael had immense lust brewing inside them—constantly, no less. When aroused, they would turn almost animalistic, only having a singular goal of relieving themself in the moment.

''Hah... hah...''

''Hhn... slow down, darling.''

Right after I took off my bra, a very different Rachael greeted me.

She, with labored breaths intertwining the throbs of her reproductive member, was glued to my bare chest. Just like her flushed cheeks, the once majestic eyes of the princess that blazed like the sun turned a deep, deep red.

She didn't hold back.

Her palms landed right on my chest, and her slender fingers started to dance around freely, fondling them whilst itching her hip below. Besides the seething clutter of heat and perhaps hardness I felt between my legs, Rachael was also quite methodical with her touches.

With mirrored motions, she would push my nipples inward with her thumbs, cup my breasts from below and jiggle them, or pull them a certain way with all her fingers grabbed onto the soft flesh.

''Huu... Your Highness...''

Right when my body also began to heat up, Rachael took a step further, pushing her searing face against my left side.

''Mn...!''

She nibbled on my nipple with her lips, sending a wave of ticklish but strangely pleasant sensation across my body. Then, as she flicked her tongue over it, that sensation quickly turned into a sudden zap, channeling a flinch.

From that point on, she completely switched to sucking on me as if her life depended on it. Perhaps she really loved my chest as she pounded on it so enthusiastically, and my moans only helped boost her spirit.

''A-Ah...''

Amidst all the lewd sounds scattering all across the room, Rachael's free hand decided it wanted to add one more into the pile—by smoothly sliding into my skirt, creeping into my underwear within, and arriving at my most precious place.

I could see her red eyes looking up at me, ones full of possessive and utter lust.

Like a predator teasing its prey, Rachael skirted my pussy at first, only stroking her two fingers along the very outer lines of the lips, almost as though she wanted to familiarize herself with the motion.

Once the princess deemed me to be serviceable, she carefully split the labia apart, stroking the inner parts gently.

Of course, after receiving so much stimulus, I was a little out of it. I was wet somewhere, and I could feel my head not working as sharply as usual. The only thing left in my mind was Rachael's almost hypnotizing red eyes and the pleasure dominating my being.

''Mhn... Cecilia. You really are...''

A look of impatience.

The princess finally retreated her offense, only to turn around and push me onto the bed half a moment later. The first thing she did after locking eyes with me was to strip my skirt and throw it aside before pushing apart my legs.

''Your Highness...''

I was a bit nervous. It was my first time, of course, and it should be that way for her, too. However, despite seeming out of breath, she was still as on point as ever.

''Call me by my name.'' She said, licking her plump, almost reddish lips.

''R-Rachael...?'' I muttered.

''Good girl.''

She smiled at me.

Her beautifully seductive smile made my heart pound harder and faster, and perhaps taking advantage of this moment, her hand slid along my thigh and pulled the critical part of my panty aside, allowing her a clear view of my most embarrassing place.

I felt like closing my legs, but she wasn't going to allow that.

Blood gushed to my face as the princess spread apart my lower lips, closely examining it with such glee that I couldn't help but whimper in shame.

''Hah... I can't hold it anymore.''

''Uuu...''

''You're drenched, girl. Perfect for... this.''

''...!''

And finally, there it was—the penis.

With a single unbuttoning, the shaft burst out of Rachael's pants, landing on top of my nearly exposed belly. The fact that it was the first time I had seen something this... vividly shaped—on top of being so long it reached my belly button—was enough to make for a surreal experience.

However, the guttural heat transferred to me, and just the sheer weight of it resting on my stomach was indeed real.

Gulp.

Would it fit... that was an unnecessary question. I knew that Cecilia's body was equipped for even more than this, but it did seem as though the batter wouldn't go in properly.

Well, I guess there was only one way to find out.

''I love you, Cecilia.''

''Mhm... me too... Rachael.''

To ease me up, the princess leaned down and began to kiss me, even putting her tongue forward for a more intimate time. One of her hands reached for my chest again while the other pinned my wrist down to the bed.

After some adjustments, the tip of her member finally slid into the right place, and from then on, she slowly, very slowly pushed her hip down.

''Mhmp...!''

Right away, I could feel my skin and flesh being stretched to accommodate the fat tip. Behind her snail-paced advancement obviously hid a furious urge to go all in and destroy everything. However, thanks to her restraint, I was able to enjoy every second of her precious phallus scraping against my sensitive flesh.

And so, she kept pushing, and it really did get more and more pleasurable the deeper she went in. Like a final piece of a puzzle falling into the place where it belonged—it was that fulfilling.

By the time her member had kissed my cervix, I was nearing a climax. As I looked up at an ecstatic Rachael, I could sense that it had fully entered my stomach.

''M-Move slowly, Rachael...'' I pleaded. ''Just a bit more...''

''...Tch.''

However, the princess suddenly snapped at something.

''It truly went in right on the first try.'' She grumbled. ''You're not as innocent as you appear, are you?''

''That's—hgn...!''

With hints of rage brewing in her blood-red eyes, Rachael pulled out almost completely before abruptly thrusting her hip down, reaching the very same spot as earlier before I could even react.

The built-up pleasure finally hit the breaking point, sending a euphoric surge that blanked out my mind for a bit. My lower body convulsed uncontrollably, and my moans began to sound strange. At some point, my legs were already locking behind her, inexplicably expressing my innermost desire to be with my love.

''Ah...''

I... came.

It was much, much better than doing it alone.

''R-Rachael...''

''...Shit. I feel like going crazy.''

Rachael was still bursting with energy. Clenching her godly-carved jaw, she got her hip moving again while lowering her head to continue marking my neck area.

Taking my moans as fuel, the princess pounded on me repeatedly, each thrust full of passion and a certain kind of possessive love unique to herself. Gradually, her speed amplified, and so did the tides of pleasure surging as her member coiled inside me. Beyond that mind-numbing sensation, I could also feel a dangerous kind of itch on my neck.

Rachael was nibbling on my skin with her sharp, fang-like teeth.

''Hah... hah... Cecilia...''

''R-Rachael...!''

Instinct kicked in at the most intense moment. Her body tensed up a bit, and her hand that was grabbing my wrist tautened, almost as if she would crush my bones at any given moment. Not only that, her hip movements began to turn feral, causing our bodies to clap so loudly and constantly it drowned out my moans.

Seemingly unable to resist the impulse, my partner finally pierced her upper fangs into the flesh of my neck—

''O-Ooh...!''

In between the princess's hot, urging breaths, a completely alien kind of pleasure spread across my body as I felt blood being sucked out of me. I wasn't sure if I was already climaxing a second time, but she had stopped moving, instead remaining at the deepest spot where she could kiss my cervix and where she would have the best chance to explode her semen straight into the depth of my womb.

''Hgn...!''

Rachael hugged me tightly—so tight that I thought my spine had cracked for a moment.

But all of that was soon drowned out... by the spurts of a scorching hot, thick liquid inside my deepest, most precious place.
