Everyday Life with a Humanboi (Chapter 11)

Lying under the bed, I thought over my situation carefully. I had taken for granted being in a house with only two monstergirls with no parental supervision, though the thought of the parents coming home was in the back of my head after the first day I came here. But now it was a whole different dynamic. The parents were not going to be easily charmed into accepting me like the daughters, so my approach had to be different in how we’d need to do this. Though I had no clue what to do. I then figured Hippa probably could think of something with as mature and intelligent as she was. And if Kora’s dad was as accommodating to her as he seemed, then getting accepted by him could be relatively painless. After all, it wasn’t as though I’d fucked Kora in her baby-sack yet, and according to my manticore girlfriend her centauress sister wasn’t in heat at the moment, so there was no way I’d knocked up either daughter.

My girlfriend walked out of the room for a moment, the sound of hooves in the distance. Quietly sighing, I decided to take a rest again, shutting my eyes. But despite my best efforts, the hard wooden floor left me wide awake with my back becoming sore from the lack of any padding. Then a familiar sensation made my heart sink.

I needed to empty the tank.

Gulping, I forced my thoughts elsewhere, but could only think of the sex I’d been having, making my bare cock stiffen. My hips wiggled. Now I wanted to cum and then take a piss! If I jerked off I could relieve the pressure but then I’d have to pee even more! Squirming in my spot slightly, I was so focused on keeping my dick untouched and bladder capped that I didn’t notice Kora next to the bed as she nudged my shoulder.

“...-uma! Kazuma!” She whispered worryingly.

“Huh?!” I jumped as my dick dripped a small bit of precum, my heart shuddering in terror.

“What ‘s wrong?! You’re spasming...”

“Um...” I blushed.

“Tell me!”

“I...”

“You what...?”

“I...Gotta piss...!”

Kora stared at me, her face bleaching.

“Um...okay, let me get Hippa,” she swallowed as she stood up and I heard typing on her phone again.

What did Hippa have to do with me needing to pee? Wait...She wasn’t going to...She COULDN’T be willing to do...THAT, could she?!

In seconds I heard the familiar clopping of the elder sister approaching as the door opened and shortly shut again.

“You ready for this?” I heard my girlfriend whisper nervously.

“Honestly, no,” Hippa huffed, her voice denoting embarrassment. “But there art no other way to do this, so let us get this over with...”

“R-Right. Kazuma, get out from under there,” my lover sighed. “We’ve got a way to get you to relieve yourself.”

“O-Okay...” I shivered. If this was what I thought it was, there would be no way I could look at Hippa ever again. The times we had sex were one thing...but if she was going to use herself to bleed my lizard...!

As I climbed out from under the bed, I saw Hippa was fully-dressed with another turtleneck and a low-reaching centauress skirt.

“Look, there has to be a better way to have me use the bathroom,” I hesitantly protested, covering myself on instinct in front of the two sisters. Hippa’s ears flapped as she looked away with her cheeks blushing. Kora pouted with equally pink cheeks.

“A-As I said,” Hippa looked back at me with meekness. “There art no other way...”

I felt my stomach quiver. This was sick, and it didn’t matter if it was the only way for me to discreetly piss! This was too much!

“Just hurry up and get under here, Kazuma...” Kora lifted up Hippa’s skirt.

“Huh?”

I froze at what I saw.

Under the black-furred belly of Hippa’s equine half was a contraption of some sort. It looked like a reverse saddle, to be honest: a large woven basket suspended under the lower body by ratcheting leather belts.

“What the...?” I blinked.

“I sh-shall carry thee about for the time being, Sir Nishino,” Hippa spoke with forced professionalism. “Thou shalt be able to use the l-lavatory this way...!”

I stood there, dumbfounded and also reviled at myself for ever thinking what I did a second prior. As expected, Hippa really did think this through!

A knock upon the door made the three of us all jounce.

“Kora? Can I come in?” The father asked with a sniffle. Guess that resort he apparently was at had some killer pollen he was reacting to.

“N-Not now, Daddy!” My monstergirlfriend called back. “Uh, Sis and I are having a private chat right now!”

“Private chat?” The dad asked with confusion.

“G-Girl-stuff, Daddy! Geeze!”

“Oh! Excuse me then, I’ll be in the kitchen making breakfast. In the mood for some pancakes?”

“S-Sure thing~!” Kora sang back.

“Yes, Father,” Hippa replied calmly.

“Alright then!” And with that, the heavy footsteps left and we were alone again. All three of us heaved a synchronized, heavy sigh.

“That was close...” I breathed.

“We haven’t time to spare,” Hippa finally spoke up. “P-Please get beneath me, Sir Nishino. Kora shall secure thee.”

Peering at Kora, I was given a re-assuring nod as I went to get my borrowed clothes back on.

“Th-That will not be necessary-!” Hippa coughed slightly.

“Wait, what?” I looked over at the heiress.

“M-My body doth give off much heat...and u-under my skirt it shall be frightfully stuffy,” Hippa explained with red cheeks as her hands fidgeted.

Looking over to my other keeper, Kora sighed.

“Sis has a point,” the manticore shrugged with a reluctant expression. “Besides, I already ordered some basic clothes off Mamazon for you the other day, Kazuma.”

“Won’t your folks be suspicious of the packages coming?” I asked with apprehension.

“Look about my sister’s room for a moment, Sir Nishino,” Hippa grumbled with discomfort. As instructed I looked at all of Kora’s belongings. DVDs, manga volumes, plushies, wall-scrolls, statues, and articulated figures of human males gave the boring, white walls and shelves every color of the rainbow. What did all of it have to do with...?

My eyes widened as I realized the answer and looked to my girlfriend, who in turn smiled weakly as her bat wings fidgeted and de-barbed tail wiggled nervously.

“M-Mom doesn’t approve of my purchases but doesn’t care to snoop...” She forced an equally weak chuckle. “And Daddy...well...he knows to respect my privacy anyways. S-So don’t worry about it! Now get under Sis so we can hide you, please.”

Not needing another reason, I climbed into the human-sized basket that had my chest and belly pressed firmly but not tightly against Hippa’s equine torso. Instantly I realized that the elder sister wasn’t exaggerating at her body temperature. My front half felt the broiling heat of Hippa’s horse-body even through her short but dense fur. Her lower chest swelled and contracted in its breathing, the heavy but consistent pounding of her horse heart reverberating against my smaller form. My still-erect dick was sandwiched up between my pubic region and a slight depression that I assumed was Hippa’s navel. My penis itself was even more sensitive to the horse-heat, sending a warm klaxon up my spine at the stimulation.

After the clicking straps were secured, my world then became dark, the skirt flipped back down as Kora spoke to her sister.

“Remember, you CAN’T sit so long as he’s there,” she instructed firmly.

“What sort of fool dost thou taketh me for?” Hippa responded coldly.

“Need I remind you who threw his back out?” Kora hissed.

“Th-That was-!” I felt the heart pound more rapidly, Hippa’s body shifting nervously as it grew hotter little by little. “AHEM! F-Fret not, I shall take the utmost care NOT to harm Sir Nishino.”

“I’m holding you to that...” Kora growled before whispering to me by the skirt. “This is just until Kumoko gets your costume ready in a week. Just hang in there and stay quiet when you’re like this.”

“Got it,” I whispered back into the hot darkness.

I then heard Kora open the door and then Hippa’s body began to move as she clopped slowly out.

With my vision compromised in my hiding space, my other senses began to already increase in perceptiveness. My head was just below Hippa’s equine sternum, her fur’s scent tickling my sinuses with her earthy but fragrant aroma as it made my heart beat a bit faster. My ears rang slightly from being above her hooves as they clacked against the hard floor all while still capable of hearing the slow and steady beating of Hippa’s large heart and breathing of her horse lungs. I wondered if she had a second heart and lungs in her humanoid chest, or anything for that matter. There was so much to learn about monsterfolk anatomy.

Effectively blind, I had no clue which way we were going until the sounds of the hooves changed to a different noise. My ride turned about and shut a door, locking it as she then whispered aloud.

“Sir Nishino, thou may loosen the straps on thine sides to crawl down. W-We art within the lavatory now...”

Fumbling in the dark, I found the set of cranking-buckles as I gave it a click, feeling my body drop an inch or two below Hippa as I nearly gasped in surprise. With three more clicks I was low enough to slide out to the rear, my bare skin contacting the cold tile floor. I could see the last six inches of light above the floor where the skirt draped above and slowly scrambled out. My skin shivered at being out in the cooler air as I looked about.

The room was the size of a dining room but lacked any furniture save a sink and squat toilet. Speaking of the toilet, it was HUGE. It was the same length and width as a bathtub from my world! Then it hit me: This wasn’t just a monsterfolk toilet, it was a monsterfolk toilet for LARGE races. I shook off the thought of the large family members using it and looked over to Hippa.

“Can I get some privacy?” I asked politely.

Hippa blushed as she turned around but did not leave.

“Uh...Hippa? You’re still here.”

The centauress was silent, then quickly put her fingers into her long ears.

I felt the color leave my face. I had to whizz while she was still in here?!

A defeated feeling cascading through me, I tried to do my business as quickly as I could. Once I flushed I went over to the sink to clean off my hands and walked up to my ride, tapping her shoulder.

Initially she jumped but then undid her fingers to listen without looking.

“I’m through. Thanks for being considerate,” I decided to be as polite as I could.

“No need to thank me,” Hippa said calmly. “Thou art worth the trouble.”

“What’s that mean?” I blinked.

“N-Nothing...Please return to the basket below, Sir Nishino. And use this,” she then reached into a pocket in the front of her skirt as she gave me a smartphone.

“What’s this for?” I asked before taking the device.

“To communicate with Kora whilst below me. The password art “Caligula3” spelled with Latin letters and a capital ‘C’ ,” she instructed.

“Ah, thanks for-...Wait, what if you need to use it?” I realized.

“I have that mobile for personal use.”

“Personal use?”

“Verily. ‘Tis intended for use between my friends, but...” she trailed off.

“But what?”

“Nevermind,” Hippa coughed. “P-Please get back within the basket, Sir Nishino, And once secure, text my sister to let her know thou possesses my mobile.”

“R-Right, gotcha,” I nodded as I crawled below the skirt and tried to strap myself in properly. It was tough doing so in the dark, and it took me just around ten minutes or so, but I managed to do it. I was about to switch on the device and bring it to my face to see when the sound of a second set of hooves neared.

Unlike the familiar clopping of Hippa, these were heavier, louder, and their stride greater as they approached. I could feel Hippa’s heart quicken and her lungs breathed heavier. I even heard her gulp.

It then hit me: it was Hippa’s mother! I recalled Hippa’s graduation photo with her mother being over 8ft tall, having tits bigger than anything I’d seen in 3D before, and essentially a more mature-looking version of Hippa. I wondered if she still remained so pristinely beautiful after the past several years since that photo. Did her breasts sag a little? Did she have laugh lines? Was she even bigger than before?? Unfortunately right then I had no way to tell and could only stay silent beneath the daughter’s very warm body.

The massive hooves approached, their clacking upon the wood sharply crescendoing as they entered the bathroom’s tiles.

“Hippa? Art thou within?” An older, more silvery voice asked from outside the door.

“Y-Yes, Mother,” my ride cleared her throat. “I shall be taking my leave in but a-“

“Fret not...mah de’ah child...” the mother yawned softly, her accent changing as she spoke. “Ah don’t need ta use tha commode jus’ yet...” She slurred slightly with a lethargic tone. Did her mother speak with a Kansai dialect? With another deep yawn, the mother rummaged through what must have been cabinets as I heard containers and bottles shift about.

“Mussy me, ah think ahm gittin’ a feva...” She half-mumbled. “An’ ya daddy’s soundin’ unda tha weatha too...” Then came the sound of a bottle popping open, followed by the sound of a cup filling with water and ending with a gulp.

“Do not overexert thyself, Mother,” Hippa advised. “Please rest up. The Spring Gathering shalt be upon us soon.”

“Ah know, ah know, de’ah,” the matriarch sighed. “Ah jus’ need ta git back on Tokyo time. Ah’ll be fine inna day uh two...” and with a turning of her form (based on the sound of her hooves), the mother left the immense bathroom, Hippa and I alone once more. Heaving a sigh, the elder daughter unlocked the door and we headed out back to the hallway after the sounds of the heavy hooves were gone.

I was a bit floored at what I heard. Hippa, who spoke extremely proper (albeit a little archaic) Japanese had a mother who spoke with the twangiest western dialect I’d heard outside of a few actors in movies. What a contrast!

As we headed down the hall, I began to take in the smell of flour, butter, maple syrup, and...something sweet and fruity. Remembering what Kora said in her sleep as well as her dad asking about breakfast, my mind bolted back to the cell phone I had with me.

Typing the password, I looked for a texting icon, finding it the same as my phone’s back in my world. In seconds I was already typing to my girlfriend to let her know how I was.

After a minute, the screen grew darker, then flashed back to bright as it lit up with a reply from Kora:

‘sorry about this! We’ll sneak you some food from breakfast once daddy finishes in the kitchen. Hang in there, kazuma! <3’

Warmed by the sincerity of my girlfriend, I tucked my arms into the basket sides with the phone wedged between my hand and Hippa’s underside.

I could hear the frying pan not too far from Hippa and me, and soon the smell of blueberries seeped under her skirt as I took in the rich smell of the fruit-pancakes. Already my mouth was watering along with my body growing hot and sweaty from being smushed up against the horse-half of Hippa.

A vibrating sensation came from my hand where I had the mobile tucked away in, prompting me to see what Kora wrote.  But as I unlocked the screen to see, I was surprised to see a picture of some sort from a different sender.

Before me was a centauress roughly Kora’s age (maybe younger) in an ornate, violet, fantasy-themed dress with much of her skin exposed on her human half. Like her horse fur, her hair was brown, the long mane on her head held in a tall ponytail (‘centaurtail’?) as she smiled at the camera in her selfie. Her human half was slender and delicate, her skin almost as pale as Hippa’s with features that looked Eurasian. But curiously, her chest was flat. I guessed that even centaurs had petite women too, like humans.

Below the picture was a text reading:

‘What do you think, Big Sister? It suits me, yes?’

‘So Hippa has a centaur sister too?’ I thought to myself in surprise. ‘No, wait, they look nothing alike. Maybe they’re cousins?’ Regardless of their relation, I had to admit she was cute. I could already feel my dick stiffen again, though this time it had been pointing towards my feet, so now it was arching up against Hippa’s horse belly. I shuddered as I felt a bead of precum drip at my tip where the hot underbelly of my ride made my cock harder.

Hippa instantly shifted with a rather fake-sounding cough, and I nearly dropped the phone in the sudden movement.

“Hm? Something wrong, Hippa?” The father asked from the side of where I was.

“N-Nothing, Father,” I heard the elder daughter clear her throat. “Just a sudden ITCH BELOW MY BELLY,” she stressed with a rather cold voice that actually made my fifth limb stiffen more.

“Oh, need the scratcher?” Their dad offered.

“Nay, Father,” Hippa took a breath. “The itch shall likely STOP if I ignore it,” she added with that same cruel tone. I’d already gone from half-mast to rock-hard, but now my ass quivered at that dominating tone. Sheesh, was I a closet masochist?!

“Oh, very well then,” the patriarch replied as I heard the pan sizzle less. “Alright girls, pancakes are ready!” He chirped as I heard the sound of hurried footsteps run around Hippa and me to the front. Guess Kora really liked pancakes...

“Thank you, Daddy!” My girlfriend said with glee as she then walked slower (but still at a brisk stride) to what I surmised was the table.

“Time to-!” She began.

“Sister!” Hippa snarled, my body shuddering at the venom in her tone.

“E-Eh...?” I heard my manticore lover ask nervously.

“Thou can wait until we art all seated and hath prayed.” Again that icy, dominating tone.

“B-But-“

“No buts!” Hippa paused momentarily. “If thou wishes to ATTRACT A LOVER, thou must behave as an adult.”

A grumble from my monstergirlfriend was the only response.

I’d had enough of this.

“Eek!” Hippa squeaked as I pinched her furred belly from below.

“What’s wrong, Hippa?” The father asked with more concern. I hadn’t let go of the skin on my ride’s belly, digging my nails into the flesh harder.

“N-Nothing, Father! I...um...Kh-! I might have s-some indigestion...and a...Hrrk!...And have a s-slight stomach pain. N-Nothing an antacid cannot alleviate....!”

Not satisfied, I kept my fingers tight, grinding the nails against the skin between them.

“Hhnnngh...!”

“Hippa, that kind of pain has to be more than gas...” the dad said worryingly. “Let me call our doctor and-“

“K-Kora!” Hippa finally blurted, the sound of two manticores jumping coming a split second after the remark.

“Y-Yes...?” The younger sister gulped.

“I-I am sorry for b-being rude.”  Taking a breath, she continued. “Th-Thou didst nothing wrong, really...” she said with a strained voice. “Thou art not a child anymore...s-so please enjoy your b-breakfast...”

I tightened my fingers further.

“AND! I am m-most certain thou shalt do very well attracting a...b-boyfriend as thou already art...!”

“You...mean it...?” Kora gulped, still shaky in her voice.

“Y-Yes! F-From the bottom of my hearts...!”

I then let go of the skin, rubbing my fingers together to find that I still hadn’t drawn blood despite how hard I was pinching. Hippa let loose a deep sigh.

“Hippa...? Are you not feeling well...?” The father asked with hesitation. “I know you’ve got a lot on your plate these days, but even you should take a rest in between things...”

“I...” Hippa began, then cleared her throat. “Yes, Father, ‘tis the truth. I am a little tired as of late, therefore I shall take a rest for a bit. Kora?”

“Y-Yeah?” My lover gulped.

“Eat to thine heart’s content,” she said with a calm but happy tone. “I shall sup upon yesterday’s leftovers later.”

“Um...Okay. Thanks, Sis,” Kora replied with some chipperness to her voice. “Oh! Let me save you a few pancakes. I bet UNDER THAT SKIRT you’ve got to be so hungry that you sound like you have a SECOND STOMACH, right?”

“Ah-! Y-Yes, please save two or three then.”

I cringed at the conversation. Their dad had to be pretty dense to not see there was something going on.

“Well, then go rest a bit,” their father finally spoke up. “I’ll make sure Kora doesn’t devour them all.”

“Oh please, Daddy...” Kora giggled with a sarcastic tone. I could just picture her eyes rolling and cheeks pinkening.

“Very well. Thank you, Father, Kora. I shall take my leave.” And with that my ride trotted off from the kitchen until her hooves’ clacking became no more. The smell of tatami mats filled my senses as I realized we were in Hippa’s room. As the door slid shut I then felt Hippa hurry to something and then stand still.

A buzz from the phone in my palm alerted me to a new message. Unlocking the screen I wondered what Kora wanted to say.

But as I opened the messages I was barraged with a wall of text-speak from a different sender than the previous.

‘You have some gall to make a fool of me there in front of Father and Kora! I thought you were better than stooping to such childish behavior! If you pull such a stunt or act ever again I will NEVER forgive you!’

Gulping, I realized it was Hippa, and that she had a second mobile. I was slightly surprised that her style of text speech was more modern than her actual way of speaking. Quickly I responded.

‘Look, the boner against your belly was an accident, and I’m sorry for that. But the pinching was intentional. YOU were treating my girlfriend like a child! What gives?! You went from a stern older-sister to a fuckin taskmaster!’

I waited for my ride’s response, and after the screen went dark it vibrated. Looking at the reply, I was greeted with a wall of text that stretched longer than the screen.

‘Have you not noticed? Kora behaves the way she does because our father keeps letting her do so. He coddles her and let’s her do as she wants without any reprimanding. I heard you yesterday state that you too were a NEET in your world, so if you plan to be with my sister for the long run then at least one of you needs to become responsible and behave as an adult. And since you’re not supposed to exist in our world, I doubt you could successfully hold a job and provide for my sister with all the commotion you would attract, therefore SHE needs to mature and become more self-sufficient even more. And DON’T count on Father accepting you just because Kora loves you, supporting the two of you financially. On the contrary, he’ll likely find a way to separate you from her somehow. If you are not someone who can take care of and provide for my sister, then SHE must be the one to become independent from our father and prove herself capable of living outside of his care. Understand?”

I laid there, suspended above the floor in a prison of cloth, wicker, and flesh, the screen the only light visible. My heart felt torn, my insides liquified, and despite the trapped centauress bodyheat around me...I felt cold, defeated even. As painful as it was to read her words, and no matter how scathing they were...I realized Hippa had nothing but valid points. Already I could hear the echoes of my parents chiding me for my lifestyle and lack of motivation from not that long ago.

We really were alike, Kora and I. But unlike me, her dad was an enabler to her habits and interests, but she also had an elder sister that wanted her to succeed even if it meant being extra harsh. And what COULD I do for Kora? Being her boyfriend was great so far, and the sex and romance we’d had in just four days was all worth it. But I couldn’t do anything for her as a human in a world of monsterfolk. I was the monster here, an abomination and affront to all that was natural here. There was no way I could do anything for Kora.

Then, I realized something: there WAS something I could do. Something only I could do. I immediately began typing madly in my epiphany.

‘Hippa, you’re absolutely right. I’m sorry for everything. From here on out, I’m going to help you get Kora to grow up. It’s been a fun four days, but now it’s time for real-life to begin. For her AND me. Tell me what to do and I’ll do everything I can to make my girlfriend a successful young woman.’

I hit ‘send’ and waited for a response. Silence pervaded the air save the thumping of Hippa’s horse-heart as it sped up slightly. Then I heard...crying?

‘What’s wrong? Why are you sniffling?’ I quickly shot to her.

After a few seconds the soft sobbing ceased and the equine heartbeat slowed back to normal.

‘It’s nothing. I was simply moved by your sudden resolve. I may never know how you came to us, but I can safely say that I’m glad you did. I’m counting on you to help make my sister be everything she was meant to be. Lady Echidna truly works in the most mysterious of ways.’

Chuckling softly, I reached up and gently patted Hippa’s equine chest at her side. I then nearly gasped when I felt her reach back and clasp my hand from the outside warmly, though momentarily.

‘So this must be destiny, huh?’ I thought to myself. ‘Not what I figured what my purpose in life was going to be, but I can’t complain one bit.’ I felt unstoppable. No man, beast, or god could get in my way of fulfilling my newfound purpose.

I’d make sure Kora and I lived a happy life together, no matter what.
