EP.78 Stepsister on the Living Room Sofa 

The next morning, the scene at the breakfast table was shamelessly ordinary. 

The angle of sunlight pouring in through the window, the savory smell of miso soup in the air, even Daiki sitting across from me with a sullen look all of it was just as usual. 

“Here you go, Yuu.” 

Akari, sitting right next to me, naturally placed rice and side dishes onto my spoon. 

“If you’re picky, you won’t grow tall, so chew everything well, okay?” 

Her tone was still curt, but the way she wiped the rice off my lips was filled with a kindness she couldn’t hide. 

It was as if last night’s sex had never happened at least on the surface. 

“Ugh.” 

Trying to act nonchalant as she ate, Akari suddenly grimaced and rubbed her lower back. 

On the surface, everything looked calm. 

But beneath, the roots were still shaken by last night’s storm. 

“Sis, are you hurt? Looks like your back hurts.” 

At my teasing question, Akari’s shoulders flinched. 

“Huh? Oh, no! It’s just… I must have slept wrong last night, it’s a bit stiff, that’s all.” 

Her face twisted for a moment as she glanced at Daiki, then she hurriedly composed herself. 

“Anyway, how’s the food? Does it taste okay?” 

She quickly changed the subject, and I nodded vigorously. 

“Yeah! I didn’t know you could cook this well, sis! I think it’s even better than Mom’s!” 

“W-what a fuss…! Stop saying nonsense and just eat.” 

Despite her cold tone, I didn’t miss how red her ears had gotten. 

The way she indulged my childishness this morning showed the “spoiled child” effect was really kicking in. 

“Tch.” 

Meanwhile, Daiki across from us looked like he’d been chewing on something bitter since morning. 

He’d come all the way to this remote country village at his girlfriend’s request, only to be bored every day and constantly argue with her. No wonder he was frustrated. 

Not that I cared. 

“Daiki, try this. The rolled omelet turned out well today.” 

Noticing Daiki’s foul mood, Akari put a couple of nicely cooked pieces of omelet on his plate. 

“Oh, so you finally feel like taking care of me, Miyano Akari?” 

Daiki said sarcastically, but he still took a bite of the omelet Akari gave him. His lips were still sticking out, though. 

“Why take it that way, Daiki? With Yuu suddenly turning into a kid, of course I have to pay more attention to him. You should be mature and understand.” 

Akari’s sighing voice had none of the affectionate warmth she once showed Daiki just the dry sense of duty you’d show a troublesome little brother. 

“Sure, whatever. Good for you.” 

He replied listlessly, poking at his rice like a sulking child. 

Akari seemed at a loss for words at his childishness, but soon tried to lighten the mood. 

“So, Daiki, any plans for today?” 

“Who knows. There’s nothing to do around here anyway.” 

Apparently, even fishing had gotten old after just a day. 

After thinking for a moment, Akari suddenly clapped her hands as if she’d had an idea. 

“Oh! There’s a small ranch nearby where you can try horseback riding! You always said you wanted to try riding a horse, right? How about it?” 

Her voice was a bit brighter, trying to lift the mood. 

It seemed to work, as Daiki looked at her with a less sour face. 

“Horseback riding? …Well, how good could it be at a country ranch?” 

He grumbled, but didn’t seem to hate the idea. 

Simple guy. 

Relieved, Akari smiled faintly. 

“Still, let’s try it. Nothing to lose, right? Yuu, you okay with it?” 

“Yeah! I want to ride a horse too.” 

“Hmm… I wonder if a kid your size can ride… I’ll call and ask.” 

Honestly, I didn’t care about horseback riding at all. 

But if it could ruin Daiki’s hopes for a romantic date with Akari, it would be fun. 

See? The moment I agreed, his face soured again. 

Still, thanks to Akari’s effort, the chilly mood seemed to ease a little until Daiki suddenly spoke up. 

“But you two why were you in the bathroom so long this morning?” 

“Cough…!” 

Akari choked at his sharp question. 

Feeling mischievous, I looked at Daiki and said, 

“Sis helped me wash my face and brush my teeth! And when I woke up, my thing hurt again, so she touched it for me!” 

“What… did you say…?” 

Daiki’s eyebrows twitched and a deep frown appeared. 

Akari, looking like she might faint, rushed to cover my mouth, but it was too late. 

“N-no, Daiki! That’s not it, Yuu just said his tummy hurt and I rubbed it for him! Kids get tummy aches for no reason sometimes! Right, Yuu?” 

Seeing her desperate, almost tearful look, I was tempted to tease her more but decided that would be too risky. 

“Yeah! When sis rubbed my tummy, it got better right away! Her hands are really magic!” 

Daiki still looked suspicious, but didn’t press further. 

He just muttered, “You two are sure being weird this morning…” and went back to his food. 

Akari finally let out a sigh of relief, though she shot me a look that could kill. 

I swallowed my laughter and continued eating as if nothing had happened. 

‘Heh, Akari’s already fallen for me completely. Now it’s time to start making moves on the other heroines. I want to conquer everyone before the summer festival. So who should I go for next Kisaragi Fumika or Sato Honoka? Such a happy dilemma makes even the food taste sweeter.’ 

After breakfast and the dishes were done, Daiki soon went upstairs, saying he was tired from not sleeping well. 

With no one to interrupt, Akari and Yuu didn’t waste the chance. 

“Ahh…♥ Ahh♥ Hngh…♥” 

In the sunlit living room, the two exchanged passionate, secret moans on the sofa. 

The TV blared with fighting game sound effects, but for them, it was just background noise to cover their heavy breathing and pounding hearts. 

“Hngh…! Uh! Yuu, wait… it’s too deep… ahh♥” 

Akari tried to stifle her moans as Yuu moved his hips on top of her. 

But Yuu just buried his face in her sweaty, ample chest and thrust his hard cock deep inside her. 

Having sex in broad daylight, right on the living room sofa where Daiki could come down at any moment, sent a thrill through Akari she’d never felt before. 

Then  

“Yawn~. I’m so bored just staying in my room.” 

Daiki’s lazy footsteps sounded from the hallway as he walked into the living room. 

Akari’s heart dropped to her stomach, and Yuu instinctively stopped moving and bowed his head. 

“I heard noise and thought someone was here. Where is everyone?” 

Keeping his eyes on the TV, Daiki slowly approached the sofa. 

As his footsteps got closer, Akari’s heart pounded like it would burst. 

‘Don’t get caught…! Absolutely not…!’ 

Thinking it would all be over if they were discovered, Akari signaled Yuu to be quiet and quickly pulled a thin summer blanket over their lower bodies. 

“D-Daiki? When did you come down?” 

“Oh, you were there? I didn’t see you.” 

Daiki stopped, surprised to see Akari’s head pop up from under the blanket. 

“Uh, yeah. I was playing games with Yuu and must have dozed off. Yuu fell asleep next to me too.” 

Akari tried to act casual, fixing her sweaty hair. 

“Must be tough taking care of the kid, huh, my dear girlfriend?” 

“Ah, haha…” 

Akari could only give a forced laugh, praying nothing would go wrong. 

But Yuu quickly betrayed her hope. 

Thrust…♥ 

“W-wait…! Ah…! Hngh…♥” 

The still-sensitive tip of his cock pressed hard against her deepest spot, making Akari tense her belly. 

Her vaginal walls instinctively tightened around him, making even Yuu grit his teeth. 

“What’s wrong? You look pale. Are you okay?” 

“N-no, it’s nothing! Yuu was tossing and turning in his sleep and almost fell off the sofa, so I caught him!” 

Daiki narrowed his eyes suspiciously, and Akari buried her face in a cushion to stifle her moans. 

“Heh. The kid sure has it easy. I wish I could be that carefree for once.” 

“T-that’s not true… Yuu may not show it, but he’s really confused inside…! Hngh…! Ahh♥” 

As Yuu’s thrusts grew faster and bolder, Akari finally buried her face deep in the cushion. 

The fact that her boyfriend was right there, and the fear of being caught, made her squeeze even tighter around Yuu. 

Even he had to grit his teeth at the intensity. 

“Really? He just looks like he’s having fun to me.” 

Daiki, apparently reminded of the horseback riding, changed the subject. 

“So, when are we going riding? Can we go today?” 

Barely able to think through the pleasure, Akari forced out an answer. 

“Oh, that…! I booked it for a few days later…! Today, the ranch is busy… hngh! Ahh! So… we can’t…” 

“A few days later? Lame. I thought we’d go right away.” 

Daiki, seemingly uninterested, turned toward the fridge. 

Just then  

“Eek…!♥♥♥” 

Yuu thrust hard against Akari’s cervix, making her cry out. 

“Akari?! What’s wrong, are you really sick?” 

Daiki turned around in alarm. 

Once, Akari would have been happy for her boyfriend’s concern, but now all her attention was on the hard thing ravaging her insides. 

“N-no, it’s nothing! I just… sat with my legs bent too long and got a cramp…” 

“What? You sounded like you were in real pain. Want me to massage it?” 

When Daiki tried to come closer, Akari panicked. 

“No, no! I’m fine! If I just stay still, it’ll go away! Anyway, Daiki, why did you come down? Were you looking for something?” 

Her desperate question distracted Daiki. 

“Oh, nothing. I just wanted a snack.” 

“I think we’re out of snacks… I can go buy some later…?” 

Even as she spoke, Akari felt Yuu moving inside her and knew she was close to the edge. 

“No need. I’ll just go to the store myself. There’s got to be a shop around here.” 

Daiki checked the empty fridge and closed it. 

“I’ll be back. Need anything?” 

“Uh, n-no… nothing…! S-so just… go…!” 

Please, just go! I can’t hold on any longer! 

Akari hugged Yuu tightly, silently begging for Daiki to leave. 

Yuu, as if enjoying her desperation, thrust even more persistently, driving her to climax. 

“Alright, I’m off.” 

Daiki hummed as he left for the store, never realizing what was happening. 

Bang  

Spurt♥ spurt♥ 

As soon as the door closed, Yuu released a flood of hot semen inside her. 

“Ahhh♥♥♥” 

Akari buried her face in the cushion, her whole body shaking as she rode out the aftershocks. 

When she finally caught her breath, her limbs still trembled. 

She was still wet and hot below, with Yuu’s cock still inside her. 

Images of everything that had happened since last night flashed through her mind. 

‘Last night in bed… then this morning in the bathroom… now here… all inside…’ 

She unconsciously placed a hand on her lower belly. 

‘Is this really okay? Is it safe to keep letting him finish inside…?’ 

Anxiety crept in, but her pleasure-soaked body and mind wouldn’t allow rational thought. 

“Y-Yuu… you almost… almost got us caught, you idiot…!” 

Trying to dispel her anxiety, Akari scolded Yuu with a breathless, satisfied look. 

But her voice melted sweetly with excitement. 

“S-sorry, sis. It just felt so good, I couldn’t help it.” 

But despite his apology, his cock only swelled harder, eager for more. 

“Sis… again…” 

“You…! We did it in the bathroom this morning and now again, and you’re still not satisfied?!” 

“Yeah!” 

At his cheerful reply, Akari let out a helpless laugh. 

When his small hands began kneading her wet breasts again, she twisted but didn’t resist. 

“Mm♥” 

If anything, she wanted him to touch her more. 

She even lifted her hips slightly, guiding him deeper inside. 

Just as their bodies were about to tangle together again  

Riiiing! Riiiing! 

“Ugh?!” 

The old house phone rang loudly, breaking the silence. 

Startled, they quickly separated. 

Who could it be at this hour…? 

Annoyed by the interruption but unable to ignore a possible call from her parents, Akari stood up, barely fixing her clothes. 

She walked to the hallway and picked up the receiver. 

“Hello?” 

There was silence, so Akari asked again, “Hello?” 

Finally, a familiar but tense voice answered. 

“Ah… Is this Ms. Miyano? This is Kisaragi.” 

“Fumika-san?” 

Akari’s eyes widened. 

Why would Fumika call at this hour…? 

Was it about Yuu…? 

While Akari’s passion was instantly replaced by worry, Yuu now standing right behind her smiled with anticipation.
