"We're home~!!!"
After finishing my encounter with Nino, I returned to the Nakano residence with her. When they reached the living room, Miku and Itsuki seemed to be studying at the table.
"Ah! Onii-chan~! Welcome home!"
Itsuki was the first to react, jumping up from her chair and throwing her arms around me.
"Ehehe... It feels kind of nice, having you come home to us, Onii-chan. Nn...! *mwah... slurp... mwah... slurp... lick... slurp... haah... lick lick... mwah... haah...* more...!"
Overflowing with joy, Itsuki suddenly pressed a deep, passionate kiss onto my lips.
"Hey...! What are you doing the moment we get back?!"
Nino grabbed Itsuki from behind, trying to pry her away from me.
"Ahhn! I wanted to do that a little longer~!! Oh, Nino. Welcome back."
"So I'm just an afterthought?!"
While Nino and Itsuki were talking, Miku silently crept up and hugged me from behind.
"Miku. I'm home."
"Yeah...! Welcome back... nn...! *mwah... slurp... mwah... haah... slurp... lick... lick... mwah... haah... lick lick... mwah...!* Fufu... It's a welcome-home kiss!"
Not to be outdone by Itsuki, she also gave me a deep, passionate kiss.
"Hey...! Even you, Miku?! What are you doing?!"
"I told you, it's a welcome-home kiss..."
"You don't need to use your tongue for that!"
"Ehh~... But it feels better with tongue?"
"Yeah..."
"You two are just..."
Nino was completely at the mercy of Miku and Itsuki's antics.
"Well then, I'll do it too! Nii...! Nn... *mwah... slurp... lick... mwah... haah... lick lick... slurp... mwah... lick... mwah...!* Fufu... thanks for the meal!"
After finishing her kiss, Nino licked her lips and gave me a seductive smile.
"See, in the end, you did it too, Nino."
"That's because you two were showing off! More importantly, what's this? Studying all of a sudden. Isn't that pointless for us?"
Nino retorted to Itsuki's comment, then spoke with slight irritation about Miku and Itsuki studying, plopping down on the sofa.
"Well, I don't want to either, but..."
"Onii-chan said if we study hard, he'd give us a reward..."
"Huh?"
Itsuki and Miku answered Nino's question while sitting at the table. And at Miku's mention of a reward from me, Nino reacted and looked at me.
"Niil, is that true?"
"Huh? Oh, I did say I'd give a reward if you studied hard..."
"Why didn't you say that sooner! That changes everything. I'll start my homework right now, so teach me, Nii!"
As soon as she heard about the reward for studying hard, Nino pulled out her writing tools, textbooks, and notebooks from her bag and sat at the table.
"Ah! That's unfair, Nino. I have questions for Onii-chan, too."
"Me too... Onii-chan, teach me this part..."
"Alright, alright. I'll teach you one by one, so wait."
For the three of them asking me to explain things they didn't understand, I patiently taught each one in turn.
"I'm done!"
"Me too! That might be the first time I've ever done homework!"
"Come to think of it... we never have before..."
"Hey, hey..."
A natural break came when the three finished their homework. However, I couldn't let what Itsuki and Miku said slide.
"Alright, I'll start preparing dinner, so you three go take a bath or something."
"Okay! I'm looking forward to your cooking, Nino! Oh yeah, Onii-chan, wanna take a bath together?"
"Huh?"
When Nino suggested they take a bath while she started dinner, Itsuki proposed they bathe together.
"Uh, but..."
"Itsuki, I have a suggestion."
"Hmm? What? I don't want to give up bathing with Onii-chan, though."
As I was hesitating, Miku made a proposal to Itsuki.
"How about the three of us-me, Itsuki, and Onii-chan-bathe together?"
"Wha...! Miku?!"
"Ehh~... But..."
I was surprised by Miku's suggestion, and Itsuki looked reluctant.
Miku then whispered something into Itsuki's ear.
After hearing Miku out, Itsuki's expression completely changed.
"If that's the case, okay! Let's go, Onii-chan!"
"Wait, I never said I would..."
"Oh, it's fine. I think it'll save time too."
Nino, whom I'd expected to oppose the idea the most, surprisingly agreed with Itsuki. Then she whispered in my ear.
"I'll show you my young naked body for the first time next time!"
After hearing that, I looked at Nino and saw her smirking.
"See! Nino says it's fine too, so let's go, Onii-chan!"
"So indecisive..."
And so, the two of them pulled me by the hands towards the changing room...
"Bath with Onii-chan! Bath with Onii-chan!"
Itsuki hummed cheerfully as she undressed. Beside her, Miku was also undressing with a smile on her face.
'Haah... how did it come to this...' I undressed with a sigh.
"Huh? Onii-chan's cock is smaller than usual."
When I was down to just my boxers, Itsuki crouched down and stared intently at his penis.
"Well, it's not hard all the time, you know."
"I heard that guys get erections when they're excited... So... ahm..."
I explained to Itsuki, who had pointed out my flaccid state, that I wasn't always erect.
Miku, crouching beside Itsuki, explained the process of getting an erection, and then suddenly took my penis into her mouth.
"Wha...! Miku?!"
"Ngm... ngm... ngm..."
Ignoring his words, Miku worked my still half-hard penis with her mouth.
"Woah~... So you can put a penis in your mouth."
" *Slurp...* Haah... See, it's getting bigger..."
Miku let my cock slip from her mouth, then stroked my now erect shaft with her hand and smiled.
"Hey, hey, can I put it in my mouth too?"
"Yeah... but it's bigger than before, so be careful... And don't let your teeth touch it..."
"Got it. *Ahm... Nngh... fnnh...! Ngm... ngm... ngm...* "
Itsuki slowly took my cock deeper into her mouth until it reached the back of her throat. Once she seemed adjusted, she started moving her head, stimulating my.
"Nngh? *Slurp... slurp...*"
"Gh..."
As if noticing something, Itsuki began to entwine her tongue around my cock while keeping it in her mouth.
