Sinner System-Chapter 412: Kai’s Birthday (Part 3)

"Alright, you ready to turn around?" Inquired Aria, as she finished massaging my legs.

"Mhm, sounds good," I nodded, before rolling onto my back as she hopped off me.

She got back on me as I turned around, straddling me before reaching down and poking my cock with a slight smirk.

"Oh, my, what a stiff muscle..."

"Sorry, Miss Nurse, I couldn’t help it," I remarked with a smile.

"No need to apologize, it’s perfectly natural. And besides, I said I’d get the tension out of every single muscle in your body...and I’m feeling a lot of tension in here," She uttered in a seductive whisper, before grabbing hold of it and picking up the massage oil with her other hand, dripping a trickle of the oil onto it.

I shuddered as she slowly and teasingly spread the oil across the throbbing length in her grasp, sliding her hand up and down.

Fuck...

As she began to pick up the pace, my heart began racing, before she let out a slight giggle as I grabbed her hips and pulled her onto me, her chest lightly thudding against mine before I pressed my lips against hers, kissing her.

I squeezed her hips as she ran her hands across my chest, sucking on my lower lip as I grabbed her ass and squeezed it firmly.

I then spun us around, putting her onto her back and meeting her gaze as we took a moment to catch our breath, before I reached down and undid the rest of the buttons on her nurse outfit, before slipping it off her.

She had nothing on under except the tights, or I guess they’re more like stockings, going high up her thighs.

I won’t take them off, I’m really liking this look...

I kissed her neck before tracing my lips down to her chest, massaging her right breast before I slipped my lips around her left nipple, twirling my tongue around it and sucking on it, eliciting a slight moan from her.

I moved down to her stomach, her back arching slightly as I teased her skin with my lips and tongue, before putting her legs over my shoulders as I got in between them, her hands running through my hair as I leaned in and flicked my tongue across, another moan ringing out.

"W-Wait, it’s your birthday, so I should be the one who takes care of you," She stuttered, before her toes curled up as I pushed my tongue in.

"It’s fine, I’m doing this because I want to...you taste real good," I smirked as I met her gaze, before she gasped as I lowered my head again, picking up the pace as I flicked and swirled my tongue around.

As I continued pleasuring her, she shuddered as her back arched up, a sharp, stuttering moan ringing out, before she relaxed and slumped, her back thudding against the mattress as she tried to catch her breath.

"Y-You’re certainly...e-enthusiastic tonight," She stuttered as a couple of beads of sweat trickled down the sides of her head.

"Yeah, the nurse outfit is really working for me...and I’m liking the sight of you with nothing but these stockings," I smirked, as I ran my fingertips down her thighs.

"Mm, glad you like it...guess I’ll have to wear it again sometime. There’s plenty of other outfits we haven’t used yet too. Now, then...why don’t you get on your back? It’s my turn," She remarked with a lick of her lips, my heart skipping a beat.

She’s so fucking sexy right now. Seriously, how’d I get so lucky. I love her so damn much...

"Yes! This is it...with this. I have perfected the upper echelon of my forces!" I smirked, as I looked around at the evolved Monsters bowing before me.

It has been around two weeks since Kaivel Intrix escaped, and now, finally, I have completed my immediate goal of increasing the quality of my forces.

It was a costly endeavor, I made twenty-seven attempts, and endured seventeen failures. Which means, ten successes, ten Monsters evolved beyond their natural evolutionary limit.

I have titled them the Sentinels, and they are easily the most powerful beings in existence.

Well, besides myself, of course.

I shall need some time to replenish my overall forces, so I cannot make use of them just yet. But that’s fine...the Sentinels need time to get used to their increased intelligence and new abilities.

After the trouble I went through to create them, I cannot afford to rush and waste them. They are all well over twice as powerful as the Archdemons and Dragons, exactly what I need to ensure my victory over the humans.

In addition to the Scythe Mantis, I successfully evolved an Ogre, a Giant Fire Slime, a Cereberus, a Minotaur, a Hypersonic Bat, a Hydra, a Phoenix, a Basilisk, and a Cull Crocodile.

Surprisingly, all of them ended up more or less within the same range of power.

There is some disparity, but the gap between the strongest and weakest among them isn’t particularly wide, even though some of them were evolved from what the humans call High Level Monsters, and the others Critical Level Monsters.

"They really are all absurdly powerful, I cannot imagine how we could possibly lose with them on our side. What of the Generals, my Lord?

Since I’m the only one left, should I select the nine strongest among the Archdemons and Dragons to replace-...?" Began Spektar.

"No need. Simply instruct them to sharpen their skills, I shall be deploying several of them once our depleted forces have been somewhat replenished," I replied with a shake of my head.

"So, uh...what about me? What is my position now?"

"Hm, I suppose something like a secretary or right hand man?" I responded thoughtfully, after taking a moment to mull it over.

I shall continue sending easy Dungeons full of weaker Monsters to the human world for a while longer, and once my forces have been replenished, I shall deploy the Calamity Level Monsters.

And once the human’s forces have been sufficiently weakened, the Sentinels shall come into play...
