One Last System

As weird as it might sound, moving from theory to practice turned out to be both extremely easy and extremely hard at the same time.

The ease of task was pretty damn simple. I stood right between Mia's spread-open legs with her naked body right before my eyes in all of its beauty. Save for what Mia managed to cover with her hands that I guided to her crotch and breast, there were no secrets that the girl could keep from me in her current position.

Yes, getting excited by the sight was the easy part. But holding myself back from moving my hips just an inch ahead proved to be far more challenging.

"For starters, let's just pleasure ourselves," I instructed while firmly grasping at my erection and slowly starting to move my hand up and down.

It's been quite a long time since I last masturbated. And when it happened, I did so with some random porn before my eyes rather than a real girl. And soon, Mia proved to be far better fap material than anything some perverts would put up on the Internet.

With a bit of embarrassment on her face, Mia pushed her fingers inside against her body. Her left hand sank into her breasts while her middle finger took a dive into her pussy, spreading it open just far enough for me to catch a glimpse of her insides.

Mia squirmed on the table, her body twitching in reaction to both the physical pleasure of masturbation and the mental excitement of being watched.

And to be perfectly honest, I wasn't any better.

I could feel the heat of Mia's crotch reaching the tip of my penis, forcing me to put even greater care not to push myself forward.

Her position, her blush, her wide open legs, her perfectly sized and shaped breasts… Every last detail of Mia's entire being was alone to turn me on all on its own. And when they all combined with the girl's reaction to her own movements, with the short squeal that escaped her lips, the twitching of her body…

I realized that contrary to what I actually wanted, I would last only for a very short moment.

"I hope it will help," Mia muttered as she added a second finger of her right hand, pushing two of them inside her pussy.

For the next few moments, we simply moved our hands and fingers a little, masturbating while openly eating the other party with our eyes.

"This isn't enough," Mia added after a moment as her lips twisted in a grimace of rejection.

Her hips swung to the sides, making it feel like it was only a matter of time before her bottom lips would scratch the top of my erection.

"More…" Mia whispered as the movements of her fingers hastened. "More!" she demanded in a pained voice, sliding her fingers in and out of her vagina at an ever-accelerating pace.

Her legs moved a little, all so that her feet would rest upon the sides of my waist. Then, she reached out with her hand and grabbed my left wrist before pulling me just a little bit closer so that my hand could reach her breast.

"This won't be a problem, right?" she asked with desperation in her voice as she locked my hand with her fingers right on top of her breast.

"I don't think it is," I replied while gulping my saliva down.

Yet, while I initially managed to keep my distance, over the course of the next few minutes, the top of my erection ended up rubbing against the wet lips of the girl's pussy anyway.

???????????????? ???????????????????????????? ???????????????????????? ???????????????????? ???????? ????????????????????-????????????.????????????

"It won't hurt to rub against each other either," Mia added in a pleading tone, clearly unable to withstand pleasure herself when my dick was in position and in a perfect state to scrap the part of her insides that her fingers could never reach.

"That's…" I hesitated for a little.

While the idea of rubbing my dick against her crotch was perfectly in line with my own desires… I was too scared.

I didn't need to test it to know that simply inserting my dick in my girl would likely lead to a hell of a danger. And even if sumata would save us from the worst-case scenario…

Not only I couldn't be sure whether it would still put us behind the line that we couldn't cross, but I was also aware that as soon as our genitals would touch, there would be no force in the entire world that could stop me from going all in!

"Please…?" Mia pleaded in a sweet, soft voice. And this single word of hers was enough to vanquish all of my decisions from before.

"Only a little, okay?" I muttered, moving my hand all the way to the base of my dick, squeezing it just hard enough to pull all of my skin along. And then, with a single jerk of my wrist, I slapped my dick against Mia's moist lips.

I didn't focus on the pleasure that came from the act, though. Instead, I put all my attention to my mana sense, watching out for any and all possible adverse effects that bringing our genitals together could have on Mia's body and cultivation.

The energies within her body shook a little… but remained otherwise stable.

"More!" Mia cried out. "Dear, please!" she pleaded with a teary expression all over her face.

"Dear…" I hesitated.

On one end, there was the risk of bringing serious harm to my beloved. But on the other hand…

The look of lust and desire in her eyes, the pained expression that filled the rest of her face, the constant twitching of her hips as she kept wiggling them around while instinctively trying to nail herself on me…

Even a single of those would be enough to break any and all mental barriers I set up in advance. And when Mia stacked all of those elements together, I felt like I had to praise the sun for the fact that I didn't lose myself then and there!

"Let's… try it," I yielded. This time, however, rather than slapping my dick against Mia's crotch, I slowly lowered it before it peacefully rested upon Mia's slimy pussy.

The girl then brought her legs together, locking my dick in a triangle of her abdomen and thighs.

"Now, fuck me hard!" Mia requested, using her inner juices to lubricate her thighs.

I pressed my hips forward, rubbing my dick against the girl's skin. And yet, despite how pleasurable even this kind of play was, my focus was only on the flow of mana within the girl's body.

And it was this focus in particular that not only allowed me to confirm my theory but also prove that Mia's suggestion actually turned out to be true.

Sure, bringing our genitals together nearly sent Mia's cultivation into disarray as it jerked the flow of her energy and forced it to raise its speed by nearly a factor of two.

Thankfully, as soon as this short distortion passed, Mia's cultivation stabilized and started to raise, fueled by the sparse amount of my yang energy coming from the precum that I rubbed dry against Mia's skin.
