"Nom... Mmm, delicious!!"
"It's just toast, no need to be so dramatic.'
The next morning. I was eating breakfast with Ichika, who had already changed into her school uniform.
That was fine, but...
"Could you move a little? You're making it hard for me to eat."
Ichika was sitting right on my crossed legs, casually munching on her toast.
"Ehhh... come on, this much is fine, right? A-And... besides, *smooch* this way, I can kiss you anytime!!"
"Yeah, yeah."
Realizing arguing further was pointless, I gave up, picked up my plate, and continued eating my toast.
"Ichika, do you have work today?"
"Yup, I do."
"Come to think of it, what exactly is your part-time job?"
Seeing a good opportunity to ask something he'd been curious about for a while, I decided to go for it.
"Hmm... you have to keep it a secret from my sisters, okay?"
"Y-Yeah... wait, it's not some shady job, is it?"
"Ahaha! No, no. The only man I'm interested in is you, Onii-chan!! So, I have zero interest in that kind of work!!"
"Well, that's good then."
"So, well... I'm working as an actress."
"Huh...!? An actress!?"
"Yeah. I got scouted in town. I did talk to our mom about it. Right now, I'm just doing training and small supporting roles!!"
"Wow... That's... Ichika, you'll probably hit it big fast. You're this cute, after all."
Hearing about Ichika's job, I smiled and answered while patting her head.
"Y-You think so...?"
"Yeah. Hey, maybe I should get your autograph now while I can."
"Ehhh... that's way too soon!! But... if I ever land a big role, your autograph will be the very first one I give out!! Fufu... maybe even with a lipstick kiss mark on it or even a pussy lipstick mark!"
"Haha... that would be quite the collector's item."
As they chatted like that, I kissed Ichika.
"Nn... *smooch*. Hey... I want some dessert."
"Dessert? There's yogurt in the fridge."
"Fufufu. It's right here, isn't it! Our own special yogurt."
Saying that, Ichika stood up, turned to face me, squatted down, and pulled down my pants and underwear before grasping my cock.
"Fufufu... you're a little hard already, aren't you! Were you expecting this?"
"No way. It just reacted to your nice scent."
"Hmm, I'm so happy!! *Nom Slurp... Slurp... Slurp... Slurp*."
"Ngh."
Ichika happily took my dick into her mouth and immediately began working it with her lips and tongue. Her blowjob technique was as masterful as ever.
"*Slurp Slurp Slurp Sluurp*... Haaah...*Lick Lick Smooch*... How is it? Does it feel good?"
"Yeah. It's incredible."
"Fufufu *Liiiiick... Liiiiick*."
Delighted by my words, Ichika focused her tongue on the sensitive underside of my shaft, looking up at me with upturned eyes.
And she was wearing her school uniform, no less. The sense of moral taboo was overwhelming.
"*Smooch* Fufufu... you're twitching so much. Are you about to cum? *Smooch Lick*."
"Yeah... I might be in trouble."
"Then shoot it all right into my little mouth, okay! *Nom. Slurp Slurp... Slurrrrrrrrp*."
"Aaaahhh... Ichika... I'm cumming...!"
"Mmph Fngf Nmu... Nmu... Nmu... guh aheah... ret ih ouu Slurrrrrrrrp."
*Throb... Splurrrrt...*
"Nnn Sirrp *Gulp Gulp Sluurp!!* Thanks for the meal *Gullp Sluurp Sluurp*."
Pulling her mouth away from my cock, Ichika opened her mouth wide to show me she had swallowed everything, then licked up every last trace of cum remaining on my shaft.
"Fufu, as thick as ever I can't wait to drink it again!"
Satisfied, Ichika gave me a bewitching smile and kissed the head lewdly.
After that, I saw Ichika off at the front door once she was ready for school.
"Well then, I'm off! Nn... *smooch Sluurp... Lick... Lick... Sluurp*."
"If you kiss my dick that much, you'll ruin all the makeup you just put on."
"It's fine! I can just fix my makeup later!"
Saying that, Ichika hugged me tightly.
"Good luck with both school and work. See you later."
"Yeah! See you later"
*Ding-dong...*
Just then, the doorbell rang in the early morning.
"Oh? A visitor this early?"
"No, I don't have any plans for... Gah!?"
Looking through the peephole, I saw the other four sisters besides Ichika, all puffing their cheeks out indignantly. Not wanting to disturb the neighbors, I quickly opened the door.
"Ah! Ichika! You've really done it now!"
"Yeah! I wanted to stay over at Onii-chan's place too!"
As soon as the door opened, Nino and Itsuki barged right into the room and started complaining at Ichika.
"Ahaha... sorry, sorry... I got so tired out by Onii-chan's amazing technique, I just fell asleep."
"Muuuh... I acknowledge Onii-chan's technique. But, I won't forgive any sneak attacks!"
"Technique? Did he give you a massage or something?"
Ichika answered with a laugh, but Miku angrily declared she wouldn't forgive her for staying over. As for Yotsuba, she apparently had no idea what they were even talking about.
"Come on, come on. I'll listen to your complaints on the way to school, so let's go. How about you all get a 'see you later' kiss from Onii-chan?"
"Oi!"
Ichika quickly stepped out of the front door and made an outrageous suggestion to her sisters.
"That's a good point. Well then, Hiro-nii... see you later."
"Fufufu... Onii-chan... I'm heading out, kiss."
"Then me too-oh! See you later! Kiss."
"Onii-chan! Make sure you pay attention to me next time! See you later Nn... *smooch*."
One after another, all four of them pressed their soft, warm lips against me in turn, and then, following after Ichika, they made their way toward the school.
'Good grief... What a wildly unrestrained bunch of sisters they are!'
-x-X-x-
That evening.
"Onii-chan, I'm done!" Yotsuba announced.
"You spelled this wrong, Yotsuba," I pointed out.
"Fweh!?"
"Onii-chan... I'm done," Miku said quietly.
"Miku, you spelled it wrong too."
"Muuu."
"All done, Hiro-nii." Nino presented her work with a smug look.
"Oh! Nino, you're as good at English as always. No issues here."
"Fufun. Well then, I'll go first." Nino leaned in and captured my lips with hers, her tongue sliding into my mouth with a wet, lingering kiss. She licked and sucked, her breath hot against my skin, before pulling away with a satisfied hum. "Mmm, delicious."
"Alright! Finished, Onii-chan!" Itsuki declared.
"Hmm... yeah, Itsuki, no problems here either."
"Yay! Then me too." Itsuki took her turn, pressing her mouth to mine. The kiss grew messy as her tongue intertwined with mine, soft moans escaping her throat while she tasted me. She finally broke away with a happy giggle.
All the sisters except Ichika had gathered at mu place to study for the regular exams next week. For some reason, a reward system had been established: solve a problem and earn a kiss from me. Naturally, that had everyone brimming with motivation.
Today's subject was English, and while Miku and Yotsuba were struggling hard against their weak spot, Nino and Itsuki had already finished and were thoroughly enjoying their kisses.
"Uuuugh... finally done! How about now?" Yotsuba asked, exhausted.
"Hmm? Yeah, Yotsuba, no problems here."
"Yay, I did it! Then." Yotsuba didn't wait.
She pressed her lips against me, her kiss eager and long, her tongue immediately seeking his. She licked and sucked, moaning into my mouth as the kiss deepened. Her tongue danced around, the wet sounds filling the room as she dragged it out, clearly wanting more.
"That's too long!" Nino grabbed and pulled me away from Yotsuba, breaking the kiss.
"Eeeeh! Just a little more." Yotsuba whined.
"I want more too, you know! Hey, Onii-chan." Itsuki couldn't hold back anymore and sent me a pleading look.
"No way. You just had yours, Itsuki," I said, pressing my palm against her forehead to stop her from leaning in for another kiss.
"Buuu! Buuu!" Itsuki pouted and complained loudly.
"Alright! This time for sure! Here, Onii-chan." Miku finally finished her work and held it out.
"Yeah. Miku, no problems. Good job."
"Finally done." Exhausted from battling her least favorite subject, Miku leaned in and kissed me. Her tongue licked and probed my mouth slowly, a tired but sensual kiss.
When she pulled back, a satisfied smile spread across her face. I felt like, if I wasn't mistaken, she was silently inviting me for more.
"Hey, Hiro-nii... Just kissing isn't enough anymore, is it?" Nino's voice was husky, her eyes half-lidded with desire.
"Yeah... I want you, Onii-chan." Itsuki added, her gaze hungry.
"Mm... me too." Miku breathed.
All three of them-Nino, Itsuki, and Miku-were looking at me with glazed, lust-filled eyes.
"Stop it. Yotsuba is here too, so that's enough for now."
"Huh?" Itsuki reacted to my words and glanced at Yotsuba. Nino and Miku followed suit.
"Yotsuba. Have you done anything else with Hiro-nii besides kissing?" Nino asked bluntly.
"Eh? Uh... um." Yotsuba shake her head, not quite understanding the question.
"Don't tell me, you've never had Onii-chan touch your tits or your pussy?" Miku's words were shockingly direct.
"Eeeeeh!? Of course not!" Yotsuba's face turned bright red at the implication.
Nino, Miku, and Itsuki exchanged a look and nodded to each other.
"Alright, no helping it. We'll head home for today," Nino decided.
"Yeah... Yotsuba, you should stay the night at Onii-chan's place," Miku suggested.
"What... just me?" Yotsuba blinked in surprise.
"Mm-hmm. You should let Onii-chan dote on you. We'll let Mom know," Itsuki added sweetly.
"Hey... you're just deciding things on your own." I tried to interject, but the three sisters already grabbed their bags and stood up, getting ready to leave.
"Seriously... You love all five of us, right? So it's totally unfair if only Yotsuba hasn't experienced anything," Nino said.
"Yeah. She needs to share that pleasure too," Itsuki chimed in.
"See you later, Onii-chan. Next time, make sure you dote on us properly." The three of them left, completely ignoring his protests.
Now, only I and Yotsuba remained in the room.
"So... what do you want to do, Yotsuba? Go home?"
"No. Um... if Onii-chan is okay with it." Blushing hard, she cast her eyes down and timidly asked to stay the night.
-x-X-x-
"Ah... Nn... Ah... It feels so good."
After eating dinner and taking a bath, both of them were now naked on the bed. Yotsuba trembled under my caresses, her sweet moans filling the air.
"Muu... It's so mean that you never did anything with me before... Ah."
"Sorry, sorry. You know... because of your history with Fuutarou, I just couldn't bring myself to cross that line." I kissed her nape while kneading her breasts, my lips and tongue tracing her neck.
Yotsuba melted under the attention, but a tinge of dissatisfaction remained from having been left out until now.
"Nn... Thank you, Onii-chan... Ah... Mmm... So you were thinking about me after all."
"Of course I was. I'd never force you. I thought maybe you still believed you might meet Fuutarou again someday, so I held back, for that possibility." I captured her lips again, my tongue sliding against hers.
"Aaaaah!" A light suck on her nipple sent a jolt through Yotsuba's body, and she came with a soft cry.
"Haa... Of course... I did consider that possibility... Ah... Mmm... But... I love you too, Onii-chan... Ah... You're always watching over me... Ah... It feels so good... I love you so much, Onii-chan... Ah, aaaaaaahn!"
Even as I continued sucking and rolling her nipples between my fingers, Yotsuba climaxed again, her body arching off the bed.
"Thank you, Yotsuba... Here." I gave her a light kiss as she lay there dazed. "What do you want to do? Should we go all the way?"
"Haa... haa... Yeah... Please... put it in." Eyes half-closed, she smiled softly.
"Alright. But first, let me get this place a little wetter." I traced my fingers along her slick vaginal opening.
"Ah... Mmm... Right there... It feels so good."
"Fufufu... Seeing the usually energetic Yotsuba moan like that is a real turn-on." I sucked on her nipple while slipping a finger inside her tight pussy.
"Ah... Aaaaah... Onii-chan's finger... is inside me... Nn... It feels incredible."
Yotsuba's insides were already drenched with arousal, but I wanted to make sure she was ready. I explored her inner walls, pressing and stroking...
