Everyday Life with a Humanboi (Chapter 3)

I screamed, muffled by the wad of folded cloth in my mouth as my jaw ached from biting so hard. The worst pain I'd felt all day did not desist in the least as the muscular tendrils realigned my spinal columns manually.

"Hm..." the doctor thought to himself as his multifarious tentacles fine-tuned my vertebrae in precise but painful tweaks. The man 'treating' me was supposedly in his fifties, but since his hair was nothing but cephalopod tentacles and his entire skin was in a constant state of changing hues and patterns it was hard to actually judge his age. Initially when he arrived the physician had fleshy hands in sleeves like a human to some degree. But the moment he began the treatment I was proven wrong in that assumption. Once he removed his coat and shirt, the arms forked into several elongating tendrils with sucker-tipped undersides.

I was gagged by one tentacle with the bite-cloth, bound at my wrists with another slimy appendage, tied at my ankles with another, and then the spinal readjustment took place. Still naked I clenched my ass tight both as a reflex to the pain and in fear of any other tentacles doing what they were infamous for in hentai.

"And you are certain this was from him attempting to lift something heavy only for it to fall upon him?" The older mollusk-man inquired with suspicion.

"Yes!" Hippa blurted impatiently. I couldn't see her but knew she was glowing bright red in her cheeks.

There was silence (other than my gagged screams and popping sounds of my spine), but finally the doctor responded,

"Understood. Ah, there we go," he spoke with an audible smile. "Seems your anatomy isn't much different after all, young man," he sighed in relief. "Alright, now hold tight for just one more moment," he advised as I relaxed a little. The pain was dulling as I panted, my back feeling hot with a blunt throbbing sensation.

Before I realized what had happened I felt a cold, slippery rod pierce into the part of me that had been 'exit only' up until then, my back arching backwards as I squealed into my gag while my dick sprang into action at full-strength. It was over in an instant, but the sensation echoed within me without any subsiding.

"There, that should help with the pain and inflammation for the next twelve hours," the doctor finally released me and freed my mouth. I felt limp, weakened, and a little dizzy at the foreign sensation. Worst of all I wanted to fap or fuck again. I was thankful to be laying on my stomach. "Have him take one tablet orally for the next three days as needed every twelve hours," I heard the cephalopod doctor hand a rattling bottle of pills to one of my caretakers.

"Thanks, doc," Kora sighed with relief. "And thank you for keeping this a secret too."

"Ah, about that," I heard the physician lather his tentacles in something wet for a moment. "I promise not to tell anyone about this, but I would like something in return shall we say..."

"Name thine price," I heard Hippa demand with venom in her words.

"Now now, Ms. Basilequos," the oct-doc chuckled. "Your family pays me well already, but what I would like in return is really an...opportunity," he began.

"What dost thou mean?"

"How should I put it? Ah. In the past there have been supposed discoveries of human fossils but all have been discredited as simply incomplete skeletons of various races with superficially human anatomical similarities. And every year or so cryptozoologists make claims of finding humans or human remains, and it always ends up as a hoax or misidentification of lesser-known races. Call it a hobby, but like Ms. Mantic I had an interest in human legends as a boy, though ultimately focused on my studies to become a doctor as I grew older."

"I hope thou art taking in this information, sister," Hippa lectured.

"Fuck you," Kora huffed.

"Young ladies, please," the doctor coughed. "Let me finish. This boy is like nothing I have ever seen in hoaxes or alleged footage. For the sake of discovery I'd like to privately study his physiology and anatomy, do blood work, and perhaps get some x-rays and MRI scans to learn more about him. He may claim to be a human but it may very well be that he is merely a mutation resulting from a host of possible genetic anomalies. Of course I can do many of these tests and studies here at your house and can arrange for special meetings for hospital visits that can be strictly confidential. If it turns out humans are an actual species this could be the finding of the century! This could be the equivalent of finding the first hexapod fossil! But of course, that can only happen with time, assuming again he is a real human."

"Do...Do I get a say in this?" I asked from the bed.

"Well, I suppose yes, young man," the doctor turned his attention to me. "You are technically a person as a sentient creature."

I didn't appreciate his way of talking to me, but held my tongue on that part.

"Uh, can I get all that in legal writing that you won't turn me into a guinea pig and imprison me against my will first? And while I can handle physicals and blood tests, how can I leave the house without making a scene?"

All was silent as the doctor thought it over.

"Ooh! I have an answer to that last part!" Kora hopped in excitement.

"You do?" The three of us all asked in unison.

"Yeah! I have an old friend from high school who could help with disguises. She does cosplay and makeup stuff for a living and is totally trustworthy."

"Wait," Hippa grimaced. "Dost thou refer to...that arachne?"

My insides clenched at hearing that word.

"Yup," Kora replied. "She's quite good with prosthetics too."

"Well, that can wait, young ladies," the doctor put his clothing back on his upper body as he gathered his bag. "Follow the directions I gave you on the pain-killers. Take them AFTER a meal and drink plenty of water, young man. If the pain feels minor you can skip a dose, but if it intensifies return to the regiment until the pain is gone for good. If there is any inflammation after tomorrow morning, call me IMMEDIATELY. Now, get some rest lad, and take good care of this boy, you two. I know your parents are gone for another three months or so, but I suggest you inform them soon about the situation here. I can also help in discussing it with them as well."

"Yes, Doctor..." both sisters replied with a gulp.

"Alright then, I'll be on my way," the cephalopod doctor said before leaving, Hippa seeing him off as I heard her hooves trot out of the room.

Sighing, Kora walked to the bedside my face was turned to, kneeling down to face me.

"Welcome to the wonderful world of monsterfolk," she said in with a sympathetic smile.

"Yeah, helluva first day already," I sighed in return. I shut my eyes as I began to rest, hearing Kora get up and walk about. Then I felt something climb onto the bed at my legs, furred paws opening my weak thighs with a lewd giggle.

"Wait, Kora?!" I gasped, my body tingling instantly.

"Shh..." the manticore girl hushed me as I felt her hot breath on my ass and balls. "Just relax, Ka-zu-ma...~" she purred as I felt my beaten body grow warm. I shivered as something hot, wet, and rough began licking at my scrotum. A large fluffy paw grabbed my dick from underneath me, firmly gripping it with its warm pads and kneading the cap tenderly. The licking had turned into suckling as I felt Kora's teeth graze my testicles as she nearly swallowed them into her hot, wet mouth.

"Sho yumfy," she murred, her voice resonating through my delicate bits. "Can't get enough of this scent and taste..." Kora trailed her licking up to my perineum, delicately nipping on the flesh with a giggle. As all of this happened I was breathing raggedly, shuddering at such attention to those areas, my rump wiggling in slight spasms of pleasure.

My eyes shut tightly. I was actually being raped by a monstergirl! Even if centaurs were my preference I felt like the luckiest guy in existence as my attacker suckled and licked my dangly parts and surrounding areas with primal hunger. I could feel precum oozing from my tip, smeared all over by Kora's thick thumb. I bit into the pillow my head lay upon, trying not to moan as my ass arched upwards on instinct. It only hurt a little thanks to the quick-acting medication, but to my dismay I felt my caretaker suddenly cease her lapping, letting go of my cock.

Buttocks still raised for a moment, I paused in confusion as my lower body descended...

...only to have my stiff member slide right into a hot and slimy hole that sucked hard on my flesh, the moist yet sandpapery tongue lashing and coiling around my dick.

"Oh fuck-!" I squealed into the pillow as I squirmed in shock. Then two large, furred paws gripped my rear end and forced me to stay in place with the blunt claws digging into my ass cheeks, lewd slurping and moaning sounds emanating from my pubic region. My eyes began fluttering in bliss as my penis burned erogenously from the stimulation. This was bliss! Nothing could ruin this heavenly-

"THOU SLUT!" Hippa' voice roared as I felt a sudden release of sperm in the surprise, the hot mouth-pussy yanked from my crotch as I bellyflopped while it still was firing fresh milk. Thankfully my erection moved with the sheets and merely got sandwiched between the bed and my lower body (still, not a pleasant feeling).

In my dick's eruptions I barely made out female voices arguing as my eyes rolled back a little and my tongue hung out, drooling into the pillow as my mind melted into a pink haze. I must have looked like a one of those ahegao-faced girls in hentai as my body quivered and my hearing actually got fuzzy for a second in my fading contractions.

The next thing I could recall was a worried, adult female voice speaking to me, clasping my hand tightly.  Sluggishly turning my face to the side, my droopy eyes began to make out the image of a gorgeous young woman with long ebony hair and dark, shimmering eyes as she called out my name.

"Sir Nishino...! Sir Nishino...!" She spoke with urgency and fright. Blinking a few times my senses were slow as I remembered who this was.

"Yyyyeeeaaaaahhhhhh....?" I slurred in my daze.

"Huh, guess the meds are in full swing now if he's sounding like that," I could hear Kora from elsewhere.

"Bite thine tongue!" Hippa turned away with a hiss. "Art thou alright...?" She asked with an almost maternal tone.

"Shhhhhyyyyyyurrrrr..." I nodded slowly. My head felt so light and everything was beginning to shimmer, amplifying Hippa's beauty.

Sighing, the goddess before me bowed her head as she tentatively kissed my forehead.

"Rest now, good sir," she cooed to me in such a ladylike fashion. "Thou hath faced many perils this day," she smiled with warmth, angels playing little brass horns in the background. "Take thy rest and thou shalt be cared for with great love and tenderness whenst thou awakens again..."

Now Hippa was clad in a divine gossimer veil with gold trim as she faded into a heavenly white light...

(---)

I awoke with a start, my body tingling a bit as I tried to make sense of things. It was night time, the crescent moon shining in through the window revealing unfamiliar surroundings, reminding me again that this was Kora's room. I sighed, relieved that it wasn't a dream. My back pain had returned somewhat and I didn't have the strength to get out of bed to walk just yet. For kicks I decided to retrace my recent memories.

'Woke up naked in a monstergirl world next to a manticore. Said monstergirl tried to tail-fuck me. Gorgeous centaur sister interrupted us. Manticore girl left the room. Browsed monstergirl's computer. Jacked it to gorgeous centaur MILF and daughter. Got interrupted and jizzed on centaur sister. Got shit knocked out of me. Was told I'd be taken to the pound. Manticore told me to fuck her sister.'

My dick twitched at the next memory. I felt warmth all over as I reminisced about losing my virginity to a real-life centaur, and a gorgeous one at that! So many monstergirl-fetishists would sell their souls and a kidney to be in my place. Then I remembered why I was in the bed.

'Centaur sister nearly paralyzed me when she fell. Lovecraftian doctor arrives to realign my spine and ends up taking my other virginity.'

I shuddered at that memory, my cock wilting under my body. But it sprang up again remembering what came next.

'Manticore girl blows me. Best orgasm I could remember up to that point in life. Centaur sister becomes goddess and takes me to heaven...'

I realized the meds had begun working at that point. Still, Day 1 in Monster World was mostly good. I then wondered if my folks missed me back in my world by now.

"Ah...Who am I kidding?" I sighed with a frown, remembering my original life from yesterday. I was a NEET hikikomori pushing 21 with no life beyond image boards and porn. Dad avoided speaking with me and Mom was always nagging me to try getting a job. Bet they were glad I was gone. Besides, I was in my ideal world now, so none of that should have mattered anymore.

Still, I felt a little bitter by that fact. With a grumble I tried to think of something else.

The sound of a door creaking made my neck hairs stand up as I tried to see what caused it. Bad idea, I realized all too late, as my back pains stabbed me again from the sudden movement.

"Good heavens!" I heard a young woman's voice cry out as the lights burst on, blinding me. "Sir Nishino, art thou in pain again?" I heard hooves clatter over to the bedside. Once my eyes adjusted I could see Hippa was beside me, though even crouching on her equine legs she towered over me.

"Y-Yeah-! M-My fault there for moving suddenly-!" I grunted.

"Nay, t'was my fault for startling thee," the centaur sister shook her head. "I merely came to check upon thee, but t'was not my intention to waketh thee at all," she gulped as she clasped my hand. "Shall I fetch thine medicine? Ah, art thou hungry as well? Thou must sup before-"

I started to laugh weakly at the young woman.

"What dost thou think is so funny?!" Hippa spurted. "I merely wish to help thee recover!" She blushed with a scowl.

"That's what's...nnngh...! So funny," I smirked through the pain. "Just this morning you were trying to get rid of me. Amazing...hrrk! How quickly things have changed between you and me, right?"

With a puffing of her cheeks the centauress looked away as she let go of my hand as if it was filth.

"Dost all of your kind behave so Ill towards others even when being cared for?" She frowned at me with a blush.

"Not all of us..." I coughed with a smile. "But yes. Some meds, food, and water would be nice please."

"V-Very well," the elder sister sighed with a nod before leaving the room. I took a deep breath and relaxed the best I could despite the searing sensations in my dorsal region.

'Guess I should have held off on the teasing,' I thought to myself. 'She probably blames herself for my predicament and is just trying to take responsibility...'

The now familiar sound of clopping hooves came near as I awaited my other caretaker. This time she sat down by the bedside and wasn't as high above me now. In her pale, slender arms she had brought in a tray holding a tall glass of ice water with a long straw, a bowl of steaming tan-colored soup (miso, I guessed), and a rather big pink tablet without any scoring on it. Yeesh, the pain-killer looked like a horse pill. At least these were orally-taken.

"Dost thou know of miso soup?" Hippa asked with concern. "'Tis a traditional soup here in Japan."

"Yeah, I like miso," I nodded, reaching out towards the bowl and spoon, only to have my hand swatted by my caregiver as she then took the utensil and blew softly onto the broth before feeding me. "Say 'ah'," she instructed neither coldly nor endearingly.

"Ah..." I opened my mouth and swallowed the perfectly warm liquid as the spoon was pulled from my lips. My eyes widened as I sloshed the soup around my tongue a bit before swallowing. My tastebuds surged with the mild but delicious flavor. Looking up at the centaur sister I blinked. "Did you make this?" I asked with a surprised tone.

Taken back by my question, Hippa gulped. "Y-Yes...Dost thou not enjoy it?" She asked with concern.

"Oh, no! I do like it," I smiled. "This is really good. To be honest..." I sighed a little. "It reminds me of the soup my mom used to make me whenever I got sick..." I felt nostalgia wash over my heart as I recalled  the simpler times when I was still in elementary school. A clattering of metal and dishware woke me from my reminiscing as I looked up to see Hippa had turned beet-red with a wide-eyed expression. Coughing to the side, I saw her lips trying to curl into a grin but was barely being held at bay by her willpower. With an uneasy, forced chuckle the older sister took the spoon and dipped it into the soup again.

"D-Do not speak such...ridiculous things, sir," Hippa laughed weakly while still red in the face. "I...merely jest! 'Tis but instant soup. Instant soup!" She laughed again as she blew into the spoon before presenting it to me. I wanted to laugh, but learned my lesson from last time and stayed quiet, taking in the meal graciously as I was fed with care.

Once the bowl was empty came the cold water to try and down the pill. I nearly choked at first but managed to swallow the large medicine with a flood of water from the straw. All dishware empty now Hippa stood and went to do the dishes as I laid flat on my belly, still naked. A chill ran up my spine as I realized I needed a blanket (and clothing). As the clopping returned I waved for the centauress to come closer.

"Hm? Art thou alright, sir?" She asked.

"Sorry, but would you mind putting a blanket over me, please? I feel like I'm gonna catch a cold if I don't."

"Ah! But of course!" Hippa nodded with a blush as she carefully pulled out the covers from underneath me and brought them to the foot of the bed. But then nothing happened.

"Uh, Hippa?" I asked with a slight turn of my head. I jumped when I suddenly felt ten slender fingers grip my ass and knead the flesh. Before I could make sense I heard an equine huff as I felt the soft features of a face plant itself firmly into my perineum and balls, huffing the skin and kissing my flesh.

"Mmmmph~!" I heard the older sister moan into my sack as her spindly fingers gripped my cheeks tight, spreading my ass as her nose went further up.

"Whoah! Wrong way! Do not enter!" I squeaked as I felt a hot, slimy, surprisingly thick tongue lap at my rosebud. A horselike whiny reverberated softly in my new assaulter's thrust as her tongue worked into the whole. "C-Cut that out!" I panicked, my voice cracking as the hot and moist muscle pieced my exit way.

Hippa moaned more as she loudly snorted into my rear as I squirmed, trying to buck her off like a reverse-rodeo.

Then suddenly I was free as I heard the centauress pant, her voice whimpering in her breaths. We were silent save our loud panting, mine in shock and Hippa's in lust. Hurriedly she covered me with the blankets and departed.

"G-Good night to thee, sir! P-Pleasant dreams!" She squeaked, galloping out of the room and shutting the light off as she loudly ran deeper into the house.

I laid in the dark, sweating and my heart racing. Kora's words from earlier rang in my ears, that her sister had a slutty side. I felt frightened at what just transpired but also had a swarm of butterflies in my belly from the experience. Raped by one monstergirl, nearly-raped by another...this really was the best day of my life!

Epilogue:

Hippa barged into her room as she panted, her mind a shaken beehive of emotions buzzing about furiously.

She had done it. She had gotten a full taste of the human boy's unmentionables. And in doing so she had rekindled that burning sensation in her heart and loins that his seed had awoken in her earlier that morning. Never had a man made her heart pound so heard and wonanhood throb so hotly. Even the most masculine of centaur men she had arranged meetings with, glistening with sweat and wreaking of manly odor had given her this great of a rush.

"Could this...could this be fate...?" She asked herself as her chest heaved. At the floor next to her resting chair lay Kora, cuddling her wretched hug-pillow that Hippa despised.

Her sister had gone from a bright and promising athlete to a dropout shut-in in the past two years thanks to anime and gaming. Hippa's stepfather, strict as he was with her was inversely lenient with his biological daughter from his first marriage and always coddled her even when her interests became so depraved. Hippa's own mother had tried to discipline the young manticore and turn her into a proper lady but inevitably conceded that her stepdaughter was just not worth the effort anymore.

Carefully walking about on her room's tatami mat floor, the centauress took her seat in her centaur bed. Her kind was polyphasic in their sleep patterns and slept with their upper half upright, so special desks with padding were the normal apparatus of sleeping for the usual 3-5 hours of each cycle. Other species had great difficulty finding the unique furniture comfortable, but to every centaur it was like a king-sized bed with feather pillows.

Situated, the centauress took a a deep breath as she allowed herself to drift off into a quick rest.

In her futon she had been forced to bring into her sister's room, Kora hugged her daki tighter as her nose twitched. Her dream added a new stimulus to it unconsciously: the addicting scent of a humanboi's body that permeated throughout the room from her sister's lips and nose as she breathed softly.
