Ren and Miku continued their exploration of the booths, enjoying the lively atmosphere.
As they were looking at a booth selling rare anime posters, two female cosplayers suddenly approached them. Their outfits were minimal, barely covering their sensitive areas, designed to attract attention.
"Hello, Mister. May we take a picture with you?" One of the cosplayers greeted with a seductive smile, her eyes fixed on Ren.
"...!?!"
Standing beside Ren, Miku felt an uncomfortable pang in her heart as her date was interrupted. She knew she wasn't officially anything to Ren, just one of many women around him. So, she chose to remain silent, holding back from saying anything despite her mixed feelings.
"..."
On the other hand, Ren looked at the two cosplayers and politely refused.
"Sorry, my girlfriend gets a bit jealous if I take pictures with cosplayers."
That was a lie. As an elite in his previous life, Ren knew very well that the cosplay industry had a dark side no less unsavory than the entertainment industry.
With a virgin woman like Miku by his side, why would Ren bother with cosplayers who were most likely no longer pure?
The two cosplayers seemed a little disappointed but still smiled.
"I see. We understand. We apologize for interrupting your date."
Then, they both bowed briefly before turning and leaving, continuing their photo hunt elsewhere.
"Wh-Who's your girlfriend? Our relationship isn't like that."
Although Miku said that, her face was flushed, and her heart was pounding.
"If I didn't say that, they wouldn't have left. Would Miku-san really want to see your brother-in-law getting close to other women?"
After saying that nonsense, Ren wrapped his arm around her waist.
Miku's body trembled, yet she didn't resist.
"As Itsuki's older sister, I have a duty to watch over you so you don't cheat. So... I'll forgive you this time."
'Nani (What)!?'
A fat otaku with glasses, wearing a checkered shirt and a backpack full of anime posters, happened to overhear their conversation.
'Wait... what was that? Sister-in-law? Brother-in-law? So, they're not a normal couple?! They... they're adulterers?! This is insane! A forbidden relationship?!'
The fat otaku swallowed hard, envy and resentment filling his heart.
'Motherfucker! Why do these riajuu always get the best?! Even a 'thrilling' relationship like this... I also want a sister-in-law as beautiful as that Onee-san, and have a forbidden relationship with her... Argh, this is too provocative for my imagination! My life is so boring compared to theirs!'
Staring at his left hand, his faithful partner who helped him relieve his sexual urges every night when watching porn videos, the fat otaku wondered why this world was so unfair.
◆━⊰✧⊱━◆
At 1 PM, Ren dropped Miku off at Café Nakano—the business Miku and Nino managed after graduating from college.
The black Bentley smoothly pulled up in front of the café's warm facade. Miku turned, a faint smile on her lips.
"Thank you for accompanying me today, Ren. It was very enjoyable."
Her voice sounded lighter than usual, like a burden lifted.
"Anytime. You can call me if you want to hang out again."
Ren's tone was casual, but there was a glint in his eyes that implied more than just a casual invitation.
"..."
Miku took a deep breath, gathering her courage. Her heart felt like it was pounding in her chest.
*CHU!*
With a swift movement, she leaned in slightly and gave Ren a quick peck on the cheek.
Warm and soft, the touch left a ticklish sensation. Before Ren could react or say anything, Miku had already opened the car door. With her shopping bags in hand and a flushed face, she hurried out.
"That's a gift for you, Ren!"
Without waiting for Ren's reply, Miku quickly entered the café, like a rabbit that had just escaped a predator. Her movements were agile, disappearing behind the glass door, leaving Ren alone with a faint smile on his lips.
"..."
Rubbing his cheek that Miku had just kissed, Ren was completely unimpressed.
"Just a kiss on the cheek? Is Miku a child? Even elementary school students don't do that anymore these days. Well, there's still time before night. Let's spend some time "farming" and planting seeds."
Picking up his phone, Ren called one of the Nakano quintuplets, Nakano Yotsuba, who was now married and used the surname Uesugi.
"Hello, Master?"
Yotsuba's cheerful voice sounded as soon as the call connected.
"Is your husband home?" Ren asked without preamble.
"No, Master. Although it's summer break, that only applies to students. For a salaryman like Fuutarou, especially working at a black company, there's no such thing as a holiday. Does Master want to come over?"
"You guessed right. So, prepare to appear in a way that can make me aroused with just one look."
"Of course, Master! I'll look my best, I won't disappoint Master."
Yotsuba chuckled softly on the other end; she was already thinking about what kind of costume would please Ren.
After hanging up the phone, Ren muttered to himself.
"I just went on a date with Miku, and soon I'll be fucking her sister." A faint smile played on his lips. "I'm truly a scumbag, but I like it."
Without the slightest hint of self-dislike for his bad nature, Ren stepped on the gas, steering his Bentley towards the Uesugi family home.
◆━⊰✧⊱━◆
20 minutes later, Ren parked his car a little distance from the Uesugi residence, deliberately to avoid attracting the neighbors' attention. He then casually walked towards the front door.
*DING-DONG!*
The doorbell rang. Soon, Yotsuba's nervous voice was heard from the intercom.
"Who is it?"
"It's me." Ren replied curtly.
"..."
A brief pause, then Yotsuba said, "I've unlocked it, please come in!"
*CLICK!*
Turning the doorknob, Ren stepped into this remarkably 'normal' home. The home of a married woman, now empty because her husband was at work.
Standing at the entrance, Yotsuba welcomed him with a wide smile and an affectionate gaze.
She was wearing only the legendary naked apron, the thin fabric barely covering the curves of her athletic body, shaped by her love for sports. The apron actually accentuated every inch of her skin, making her look incredibly seductive. With a teasing movement, Yotsuba swayed her hips.
"Welcome back, Master ❤️. So, do you want to eat first, shower first, or... do you want me first~?" She said in an uncharacteristically flirtatious tone.
"Still need to ask?"
Ren stepped closer, his body now directly facing Yotsuba. Without waiting for an answer, he pulled the girl close and brutally kissed her lips.
This was not a sweet or affectionate kiss. Ren's lips forcefully devoured Yotsuba's, his tongue pressing inward, asserting his dominance. The kiss felt vulgar, full of wild passion, without a hint of romance. The wet sounds of lips smacking and tongues entwining filled the silence.
Instead of resisting, Yotsuba wrapped her arms around Ren's neck, pulling her body closer. Her legs instinctively crossed around Ren's waist, clinging tightly like a koala to a tree, deepening their body contact.
"Mhm~"
Her breath hitched, a suppressed groan escaping her throat as Ren's kiss grew more aggressive, tasting every inch of Yotsuba's mouth as if she were a long-awaited delicacy.
"Time to eat the main course."
Seeing Ren lower his pants, Yotsuba pleaded.
"Let's do it in the room, Master."
"Denied."
Ren ignored the request, lifting her apron, revealing the married woman's wet cave. Without further ado, he entered Yotsuba directly from the front.
"Ah ❤️~"
Even though they were standing at the house's entrance, their desires were unstoppable. Ren pushed Yotsuba until her back was pressed against the wall next to the door.
*PA!* *PA!* *PA!* *PA!*
The rough sound of hips colliding began to fill the silence of the house, accompanied by Yotsuba's increasingly uninhibited moans. The apron she was wearing shifted, revealing more of her skin and tempting curves.
*PA!* *PA!* *PA!* *PA!*
Ren gave no quarter; each thrust was deep and powerful, satisfying a long-suppressed thirst. Yotsuba, with her legs wrapped around Ren's waist, responded to every movement with burning passion, her head thrown back, eyes closed, savoring every thrilling touch and thrust.
Ten minutes later, Yotsuba reached her first orgasm, but Ren didn't stop there. Without breaking their connection, he carried Yotsuba's body, still united with him.
His steps were steady, moving from one room to another, making every corner of the house a silent witness to their passion.
*PA!* *PA!* *PA!* *PA!*
In the kitchen, Yotsuba was seated on the cold counter. Her hips lifted with every one of Ren's thrusts, the intoxicating sounds of moans mixing with the friction of skin.
*PA!* *PA!* *PA!* *PA!*
Then, Ren carried her to the living room. Yotsuba wrapped her legs around Ren's waist, her back pressed against the soft sofa as Ren continued to thrust into her. They moved in a primal rhythm, disregarding etiquette, as if the world belonged only to them.
*PA!* *PA!* *PA!* *PA!*
From there, they moved to the bathroom. The humidity and the reflection of light from the white tiles added to the intensity of the atmosphere. Ren leaned Yotsuba against the shower wall, cold water splashing on their skin, heated by passion.
*PA!* *PA!* *PA!* *PA!*
Finally, they arrived in the main bedroom, the married couple's room. Ren laid Yotsuba on the bed, continuing his actions at a slower but deeper tempo, ensuring every touch and thrust delivered maximum pleasure. Yotsuba was now completely lost in euphoria, arching her back, groaning loudly, and begging for more.
Not a single part of the house was missed!
