"Nn... nnn..."
'What's this?' There was a strange, fidgety sensation in Yoshida's lower half.
As he slowly opened his eyes, the first thing he saw was Miku's face, her eyes wide open, staring intently at him.
"Miku...?"
"Ah... Onii-chan, good morning... Did I wake you...?"
"Hmm?"
He felt a bit puzzled by the apologetic look on Miku's face, so he shifted his gaze down towards his lower body.
There, he found Miku's hands, both of them working on his dick.
"Um... what are you doing?"
"Ugh... This is... well... I woke up a little while ago too... and Onii-chan's penis had gotten so big... so I thought I'd try to make you feel good..."
Her face was bright red with embarrassment, and her eyes darted around nervously, but her hands never stopped moving.
"No, this is what they call morning wood. It's just a physiological reaction for guys. It'll go down on its own, so you can stop now."
Despite his explanation, Miku's hands kept moving.
"Um... Miku?"
"Ah... well...? Touching Onii-chan's penis like this... it's... it's making me want to have sex..."
"...Huh?"
When he spoke to Miku, who still hadn't stopped her movements, an unbelievable answer came back.
"Hey... put it inside... "
"What, right now!? Come on, we don't have time..."
"It's okay... it's only five o'clock..."
He checked the clock as Miku suggested, and sure enough, it was just past five.
"Hey... is it... no good...?"
Miku pleaded, speeding up her hand movements. How could he possibly refuse when she asked him like that...
"You're such a horny girl. I guess I have to take responsibility, huh?"
"Mm-hmm... Take responsibility... Nn... churu... haah... chu... ah... NNn... "
He kissed Miku while squeezing and kneading her breasts.
Since Miku had been sleeping naked since yesterday, when he touched her chest, he could tell her nipples were already erect.
"Miku, your nipples are all hard like this..."
"Ah... nnNn... nnNn... haanNn... "
As he pinched and rolled her nipples between his fingers, Miku's voice grew sweeter and sweeter.
"Could it be... you're all ready for me down here too?"
Yoshida said this as he brought his fingers down to her pussy and slipped one inside her vagina. It was already wet, making a squelching sound every time he moved his finger.
"Haaah nnNn... no... already... put it in... "
As if reaching her limit of endurance, Miku pleaded with him, her eyes glistening with tears.
Yoshida sat up, took out a condom, and put it on his cock.
"Nnn... do you really have to put that on...?"
"Well, if we don't, you might get pregnant, right?"
"I don't mind... I want to have Onii-chan's baby... "
Just as he finished putting on the condom and positioned his penis at her vaginal entrance, Miku said those words.
"No way, Miku. You're still a student. You could get expelled, you know?"
"NnNn... haahn... I don't care if I don't go to school anymore... nnNn... studying is too hard and not fun anyway..."
"Miku..."
"No matter how hard I try... nnNn... I can't keep up with classes other than my favorite subject, history... haaahnNn... so, it's fine if I don't go to school..."
He remembered Yotsuba saying something similar before. It really shows how high the level is at Asahiyama High School...
"I can teach you if you're struggling with studying, so how about you try a little harder?"
"Hmmm... if I try hard, will you have sex with me again...?"
"Alright. I'll give it to you as a reward, so please bear with the rubber for now."
"If Onii-chan says so..."
"Thanks. Well then, I guess I need to give you that reward right now."
Yoshida smiled at Miku, who had somehow been convinced, and moved his hips forward.
"Ah... ah... it's going inside... "
Because they had already done it once and Miku was so wet, he was able to slide it smoothly all the way to the base.
"How is it? Does it hurt?"
"Mm-hmm... I'm happy because I can feel Onii-chan's cock inside me!!! Hey, move... "
In response to Miku's smiling face, he repaid her by moving his hips.
"Ah... nnNn... good... haan... nnNn... more... you can go faster... "
"Yeah? Then...!"
Giving in to Miku's words, he lifted her hips by the waist and sped up his thrusting.
"Nn aa... that's... good... it's... hitting my... deep spot... feels so good... "
"Ahh! It feels good for me too, Miku. Your insides are squeezing me so tight...!"
"Really...? I'm glad... ah, nnNn... no... haaahnNn... "
After lowering her hips, he leaned forward, kissing her lips while moving his hips even faster.
"NnNn... churu... feels so good... jyuru... haahn... nnNn... churu... I'm... gonna... cum soon... "
"Go ahead. Let me see that face you make when you cum...! Chu..."
"NnNn... churu... rero... rero... ah, nnNn... I want... Onii-chan... to cum too...!"
"Ahh! I'm about to cum too...!"
"Mm-hmm... Cum... cum... ah, aa nnNn... let's... cum... together... "
As he announced he was close to his limit, Miku wrapped her arms around his back, pulling him into a tight embrace.
"Chu... churu... I'm... gonna... "
"Chu... nnNn...!"
"Nn, nnNn nnNn nnNn... "
Splurt… Gush...
With one final thrust, he buried his penis deep inside her as they kissed, and they were able to cum together.
'Haah... haah... As always, she's so tight...! It's hard to even pull out.'
"Haah... haah... Onii-chan's penis... is twitching... It feels so good... "
"Yeah. Miku's pussy is squeezing me so tight, it won't let my dick go."
"Hehehe... I really don't want to let it go, so it can't be helped... Nn... chu... slurp slurp slurp... haah..."
He pulled away from Miku, satisfied with their kissing, and withdrew his cock.
The condom was filled with a large amount of cum.
"Amazing... so much... "
"Haha, that just means how good your insides felt, Miku."
He said this while disposing of the condom and cleaning up, using tissues to wipe Miku's pussy, before changing into his jersey.
"Onii-chan, are you going somewhere?"
"Yeah, I'm going to keep Yotsuba company on her jog. We talked about it yesterday, remember?"
"Now that you mention it, I think you did say something like that...?"
Miku sat up, still completely naked, recalling the events of the previous day.
"Miku, put some clothes on. You'll catch a cold."
"Mm-hmm... Oh, I know. Can I wear the clothes Onii-chan was wearing...?"
"Huh? Sure, I don't mind, but they won't fit you right."
"It's okay... sniff... haah... It smells like Onii-chan..."
'Ah,' he thought, 'so that's it.'
"Well, I'm heading out then. You still have some time, so get some more rest, okay?"
"Mm-hmm... have a safe trip... chu..."
Yoshida gave Miku a light kiss before heading to the entrance. Yotsuba was already waiting for him there.
"Good morning, Yotsuba. You're up early."
"Good morning! Onii-chan!"
As soon as he greeted her, she hugged him tightly...
