Itsuki, after the kiss, looked down shyly…
"Hehehe... If you get this embarrassed, you won't last what's coming. Let me show you an adult kiss now. You do the same, okay...?"
Saying that, Rena emerged from under the covers, still naked, and kissed Yoshida deeply.
"Mmm... Chu... Hah... Kiss... Slurrp Slurrp... suuck... Hah... Slurrp... Churlu... sllurp..."
After kissing for a while, Rena separated from him and urged Itsuki.
"Now... You use your tongue like that, okay?"
"Y...yeah! Onii-chan, please."
"Alright"
"Mmm... Chu... Hah... Hamu... Churlu... Chiro... Hah... Chiro... Chu..."
Tentatively, Itsuki began licking his tongue.
'No good. I can't hold back any longer!'
"Nmmu...!? Slurrp Slurrp... Churlu... Hah... Onii-chaaaan... Slurrp Slurrp... Churlu... Hah... Slurrp Slurrp... Churlu... Hah... It feels so gooood... Chu..."
Yoshida forcefully took Itsuki's lips, tangling his tongue with hers. At the same time, he began groping her chest over her clothes.
"Nnn... Ah... Onii-chan is... touching my... boobs... Nn... Chu... Churlu... Nnn... It feels so goood..."
He started removing the aroused Itsuki's clothes. Beneath her clothes, breasts the same size as Miku's were revealed.
"That's cute lingerie."
"Uu... If I'd known this, I would've worn something more mature..."
"Not at all. It suits you perfectly."
While kneading her breasts over her bra, he took her lips again.
"Mmaah... Churlu... Hahh... It feels so goood... Touch me more... Onii-chaaan..."
While kissing, he unhooked Itsuki's bra and began kneading her directly, of course, pinching and tweaking her nipples too.
"Ah... Nnn... Ah... That's good... Nn... Ah..."
"Hehehe... Hey, Hirokazu-san? Could you please attend to my breasts as well?"
Perhaps aroused by watching Yoshida and Itsuki, Rena drew closer to him.
"Yes... Sluurp..."
"Haaaahhnn... As I thought... Hirokazu... san's... tongue... feels so good..."
"Mommy... Ah... You look... like you're feeling so good... Nnn... Hey...? Onii-chaaan... Mine too... Please suck..."
Maybe excited from seeing Rena's pleasured state, Itsuki made such a request.
"I know. Okay then... Sluurp..."
"Nnaah...! Onii-chan is... sucking my... nipple... Ah... Ahn... No... This side... feels better..."
"Haaaahn... Hirokazu... san's fingers... their skill... Nnn... Is also... quite something... Ahn..."
Damn! Hearing the moans of the mother and daughter together was only driving his excitement higher and higher.
Unable to hold back any longer, he first brought his fingers to the slit of Rena's pussy.
"Ahn... Your finger... Just... put it in already..."
It was definitely wet enough that there would be no issue. While sucking on Itsuki's breast, he inserted his finger into Rena's vaginal depths.
"Ahn...! It's here... Good... Your finger... feels so good..."
Then he put his other hand under Itsuki's skirt, moving his fingers as if tracing over her panties.
"Ah... Ahn... There is... dirty..."
"Hehe... There's no place on Itsuki that's dirty."
"Nn... Chu... Nnn! Churlu... I'm happy... Onii-chaaan... More...!"
"Aahn... No good... Hirokazu... san... You're only hitting... my weak spots... No good..."
Rena seemed close to coming.
"Really no good? Slurrp..."
"Nnn... slurrrp... N-no... More... More..."
Confirming that Itsuki's panties were becoming damp, Yoshida slid them aside and touched her pussy directly.
"Nnaah... Ah... Ah... What is... this...? A, ahn... Something's... coming...!"
"Churlu... Nnn... Haaaahn... It's alright... Itsuki... Just... surrender yourself to Hirokazu-san... A, ahn... No... I'm... already..."
Itsuki's insides were also quite slick now, so he inserted his finger.
"Fwaaaaah... Ah... Ah... Ah..."
It seemed Itsuki came lightly just from the insertion. But he didn't stop. He continued exploring her vaginal walls with his finger.
"Ya... Ah... Ah... Onii... chan... No... That... Too much... already... already... Higu..."
Good, he found Itsuki's spot too. Now for the rest...
"Fwaaaah... I'm... going to cum...!"
"Cum for me, Rena! Itsuki, you cum too!"
"A, aaaaahhhhhnnn...!"
"Yaaahhnn... Already... I can't... think of anything...! N, nooooooaaaahhhhnnn...!"
Splash... Splash...
Squirt gushed from both pussies. It seemed Itsuki was quite sensitive too.
"Ah... Ah... Ah... That felt... so good..."
"Fuah... Ah... Ah... I came... in front of Onii-chan..."
"Wh-whoa..."
As both looked ready to collapse in near-unconsciousness, he hurriedly supported them.
'Good thing I kept up with jogging and workouts.'
"Hirokazu... san... "
"Yes... Nn..."
"Chu... Churlu... Hah... slurrp... Churlu... kiss... Chu... Hah... Really... I don't think I can live without Hirokazu-san anymore~!!!"
"I'm glad. Itsuki too... Nn..."
"Chu... Hah... Onii-chaaan... Churlu... slurp sllurp... Churlu... Hah... I love you so muuuuch... "
Both Rena and Itsuki smiled with utterly melted expressions.
"Well then, the time has come. Itsuki, you're wet enough like this, so it should be okay, right?"
"Nnn... Y...yeah..."
Rena confirmed Itsuki's readiness while checking the slickness inside her.
Feeling Rena's finger, Itsuki nodded with an air of determination. Then she took off her own panties.
"H, how is it... Onii-chan...?"
"Yeah, it's really beautiful. Almost too good for me."
"No. This body of mine belongs to Onii-chan." Itsuki answered with a shy smile at his words.
"Now then, Hirokazu-san, please undress and lie on your back on the bed."
"Understood."
Yoshida also hooked his thumbs into his underwear and pulled them off in one go. His fully erect cock was revealed.
"Eh? It's bigger than when I saw it before?"
"Hehehe... A man's penis grows larger like that when he's excited. The fact it's gotten this big is proof he's excited for us."
"I... is that so..."
While listening to Rena, Itsuki couldn't take her eyes off his dick.
"Oh, and Hirokazu-san? You have condoms, right?"
"Yes. There are still some left."
"Condoms?"
As Rena took a condom from the drawer to prepare, Itsuki voiced her question.
"It's something you put over a man's penis. It's called a contraceptive, and it's necessary to prevent having a baby."
"Eh, but I want Onii-chan's baby?" Itsuki's words made him incredibly happy. But...
"You're still a student, right? Also, if you got pregnant, you might be expelled from school. The school you attend now is that strict."
"That's true, but..."
Itsuki seemed to understand logically but wasn't fully convinced, leaving Rena at a loss. So Yoshida made a proposal.
"Alright. Since it's your first time, we'll do it raw as you wish. However, you'll take the pill afterwards."
"The pill?"
"Yes. It's also for contraception. Taking that pill prevents pregnancy. While you're a student, please bear with using either the pill or condoms."
"Uu... Okay..."
Finally convinced, Rena gently stroked Itsuki's head. As Yoshida lay on his back, Itsuki straddled his cock. Rena placed her hands on Itsuki's shoulders…
