Everyday Life with a Humanboi (Chapter 4)

Warmth cascaded throughout my belly and hips as I felt a warm and wet suckling at my dick. My body shuddered at the sliminess and heat that engulfed my fifth limb as I started panting.

Kora was sitting atop my stomach with me on my back like yesterday. She was naked, her womanly bits in full display as she grinned sadistically down at me. Her tail was sucking fiercely upon my dick, somehow swirling and constricting about the length in an agonizingly slow pace. Her uncovered tits were each the size of grapefruits, the areolas a bright crimson that went well with her light bronze skin, and her nether region was smooth and bare, oozing with musky nectar

"L-Let me cum...!" I protested weakly in my throws of pleasure.

"In...In a moment..." she smiled insidiously in a voice...that didn't fit her expression whatsoever. It was a gentle, tepid, and a bit embarrassed in its tone. Then I felt that demonic tail swallow my balls with my cock whole, the thick muscular sloshing stimulating every inch of my genitalia as a bolt of electricity shot up from my belly to my dick.

Sweet, white-hot release rocketed out of my rod as my back arched painfully, thrusting my hips into the tail-pussy. I spasmed like never before as I saw Kora pantomiming a haughty, bullying laugh...but the sound was completely replaced by a whimpering moan like a badly-dubbed movie. My world became hazy and dark as my afterglow cascaded throughout my form, settling me back down into an exhausted and limp state, the sound of suckling and gulping becoming the only thing I could hear in the black void.

Slowly, the sensation of my dick being released sent a chill through me as the wet flesh was exposed to the cooler air. I shivered in both post-orgasmic sensitivity and temperature drop around my increasingly flaccid penis and testicles. Something warm and soft then delicately wiped my reproductive organs dry with steady, gentle strokes until the moist sensation was no more. I heard a rustling of fabric as I then felt warm, comfy, and secure. The last thing I recalled was a soft, hot sensation press against my cheek with a light smack before I descended into a deep slumber.

(---)

I awoke slowly to the sound of clicks and keyboard strokes, a female voice making hushed sounds from the other side of wherever I was.

Groggily my eyes opened after the initial sand released my lids as I blinked. I looked to the side to see wall scrolls of anime monsterfolk and a few human men. A slight thunder rumbled in my back's sensations as I felt sore but not nearly as bad as before. Sluggishly, I tried sitting up in the bed as I managed to get my back mostly parallel with headboard.

The typing and clicking immediately ceased as the female voice gasped.

Looking up, I saw a manticore girl leap from her seat at a desk and softly land on her digitigrade, purple hind-paws as she rushed to my side.

"Shit! Are you okay, Kazuma?" She demanded in a worried tone and expression. "Do you need another pill? Wait, you gotta eat first! Let me go-!" She froze as I managed to hold up my hand to silence her.

"It's cool," I yawned. "I'm not gonna need that pill right this second. The pain's kinda dull at the moment anyways," I lied a bit. My back wasn't feeling like a freshly assassinated Roman leader's anymore, but instead felt like it'd been trampled lightly instead of stabbed. Blunt pain was just easier to endure.

"Oh...Okay then," the manticore girl sighed in relief as her sub-melon breasts heaved a little. I got a good look at her ensemble this morning and found it not too different from yesterday. Her shirt was a overly wide-collared t-shirt that hung to the side, exposing her tan shoulder (along with evidence of lacking of a bra). Her shirt hung loosely at her lower belly, showing her body's bottom half was clad in a new pair of hotpants. She seemed to favor dark colors, as the shirt was black and her shorts were indigo.

Taking a seat next to my side on the bed, I could see the back of Kora's shirt bulge from the chitinous tail draping over to the other side of her body.

"Sleep well, I take it?" She asked in such a coy tone and smile that I couldn't help but blush.

Remembering the tail-fuck, I gulped, coughing a little.

"Y-Yeah, thanks to you of course," I grinned. I had to put on the face of an alpha from here on, I decided. Couldn't let Kora think I was gonna submit to her that easily.

Blushing, the redheaded monstergirl blinked. "Wh-What's that supposed to mean?" She asked with an embarrassed and uneasy smile.

"Ah, don't try to hide it," I nudged her shoulder with my hand playfully. "I was awake when you did it." I had a sly wink.

"Did what?" My caretaker began blushing harder, a nervous look in her eyes. "I have no fucking clue what you're-"

"TAIL. SEX. We should do it again when my back heals up all the way," I smiled. But then I felt shock at seeing Kora's face. She looked spooked beyond belief as she gulped.

Looking to the side, she lightly scratched her flushed cheek with her large paw as Kora began to sweat.

"Uh...Kazuma...I th-think you had what we call a 'wet dream'." The manticore girl laughed weakly as she made eye-contact with me slowly. "I haven't...gotten a chance to use my t-tail yet...B-But I'm happy you feel that way about me!" She sputtered with a happy (albeit crazed) smile, clasping my hand in her large, warm paws.

"No no no no..." I shook my hand out of her claws. "I've had wet dreams. This was WAY too vivid to be one, and besides," I pointed to my flat crotch. "I can't feel any cum at or around my dick, plus I don't even have morning-wood," I added with confidence. "Clearly we had tail sex."

Her bright yellow, feline eyes wide, Kora turned around and flipped my sheets off. Before I could react my limp dick was soon in her firm grasp as the monstergirl began sniffing and lightly tasting my cock hurriedly. She took one big whiff and then made a sound I had never heard before.

It reminded me of a lion's growl but was muffled from within Kora's throat despite her mouth opening to reveal her carnivorous teeth and furrowed brow.

"That...That..." she snarled in a duet of her human voice and a deep, rumbling voice that was anything but human. "BITCH!" she roared, the windows rattling slightly as I flinched from the nightmarish sound coming from such a cute girl.

Clopping approached the room quickly as an already dressed Hippa hurried in with a concerned look.

"What hath happened, sister?!" She demanded with a troubled expression. "Ah, art thou alright this morn, Sir Nishino?" She immediately turned to me as she approached.

"STAY BACK YOU ASS!" Kora snarled in her demonic voice, hopping onto the bed on all fours around me. Her wings were opened wide in offensive display while her tail curled up like a scorpion's threateningly with the spikes aimed at her sister.

Shocked and startled, Hippa stepped backwards uneasily.

"Wh-What hath possessed thee, sister?!" She gulped. "Hath thou lost thine senses?!"

"You listen, CUNT," Kora growled. "STAY. AWAY. FROM. KAZUMA. He's MINE!"

I had nearly pissed myself at the scene right in front (and on) me, terrified of how radically different Kora had become so suddenly.

Hippa stared in disbelief at her sister's words, finally frowning as she sighed.

"Lay down thine weapons, sister. We shall be civil about this."

"No!" Kora snapped back. "This stops right here, right now! Leave him. I found him first, and he's everything I've wanted a boy to be like! You are NOT taking my perfect idea of a man, got it?!"

I felt frightened and also shocked. Why was Kora being so clingy with me so soon? We'd just met yesterday, and sure, she had a fetish for humans, but she was acting like we'd been dating for months!

Rubbing her sinuses, Hippa sighed again.

"Art thou putting the cart before the horse?" She responded firmly. "Thou barely knows this man before us, so by what divine right dost thou have ownership of him?" She asked with flushed cheeks.

"Squatters' rights," Kora spat back. "And besides, Mom's trying to get you married off to a well-to-do centaur household to maintain your family's strong bloodline and status. You have no right to get a boyfriend of your own choosing. I've n-never even had a boyfriend," the manticore sniffled. "S-So just let me have this one chance at happiness!" Her scorpion tail was lowering, leaning backwards to the opposite end while her bat wings wilted along with her tall cat ears. She wa sobbing now, albeit trying to fight her tears.

"Sister," the centauress approached with a concerned voice, but Kora immediately sprang back into a defensive pose with a bestial growl, forcing the older girl to jolt back again with a clattering of hooves.

"Kazuma is mine. So don't EVER touch him again..." she sniffled angrily. The dark-haired sister frowned again as she turned her nose up with a huff, leaving the room at a steady pace.

After the centauress left, Kora finally loosened all over and crawled over to me, curling up to my side as she began sobbing again. Her paws gripped my arm as if it was her only way of making sure I stayed. Leaning into my bare shoulder, she held my arm tightly as she tried to speak.

"Don'...don' leab me..." she blubbered softly. "I don' wanna be...alone anymore..."

Forcing myself to endure the pain, I turned over to face the younger sister as I tentatively reached for her head and held it to my chest now, rubbing her soft crimson hair. I felt her body scoot closer into mine as Kora's tail draped over my side and hold me firmly against her in return.

'Hell of a way to start Day 2...' I thought to myself with concern. We both laid there, keeping close to one another as I heard Kora's breathing grow softer and softer, until a slight snoring came from her as I decided to rest some more.

It finally dawned on me then: the tail-fucking was a wet dream, but yet it wasn't. Someone did milk me last night, but it wasn't Kora.

Hippa had pounced me last night.

I felt my dick twitch at the thought, but I soon grew limp with the feeling of guilt I was hit with. Now that I thought about it, Hippa had gotten more attention by me than her sister, and Kora was the human-fetishist. It made sense why she'd get like this. Not that I disliked Kora, but her sister was right; we only just met and yet she was claiming me like I was a thing to take ownership of. If anything, I was no different with Hippa to some extent by being a centaur fanboy. But last night when she had served me soup I got to see a side to her that made her more than just fetish fuel for me.

I also knew Kora's situation all too well. She must have been too much of an otaku with human fetishes that she could very well have been a social outcast even in this world.

I wondered if Hippa liked me the same way Kora did, that me being something novel was just so damn alluring on its own. Was I just fetish fuel to them both?

I'd read romance hentai with sisters or friends fighting over the same guy for years but never would have conceived it would happen to me...nor did I fully comprehend the grave feeling of being in such a rough spot between two close people.

Neither sister wanted to share me, and while I liked the older one instinctively I couldn't help but wonder if Kora might not be so bad instead. She seemed like a good girl aside from her deviant behavior, and we kinda were alike in lifestyles it seemed.

As I slowly drifted off into a light nap, I decided that I needed to really get to know these two sisters better in order to have this work out one way or another. It wasn't my choice on becoming the mate here, but I'd try to make sure things would work out regardless of who ended up with me.
