Among the women who had sexual relations with Ren—Nakano Itsuki, Maria Mikhailovna Kujou, Hayasaka Ai, Nakano Yotsuba, Alisa Mikhailovna Kujou, and Momobami Ririka—Yotsuba was the most resilient and had the greatest libido.
The proof? Ren and Yotsuba have been fucking for over four hours, with a short break to re-energize before continuing.
7:10 PM.
The warm light of the dining room enveloped Ren, who sat casually in one of the chairs, while Yotsuba sat comfortably on his lap. More than that, their genitals were still connected, creating a continuous sensation.
"Master, ah~n."
With flushed cheeks, Yotsuba used chopsticks to feed Ren a piece of food. Ren's hands weren't idle, gently squeezing one of her plump breasts, but Yotsuba seemed unfazed.
"How's the taste, Master?"
"Eating food while eating the person who cooked it. Quite an interesting experience."
"Hisss~"
Ren's words were followed by a strong upward thrust, instantly making Yotsuba tremble violently.
"Ahhh ❤️."
A stifled moan escaped her lips as her body tensed. Suddenly, a clear liquid gushed out, leaving a warm sensation that soaked Ren's lap.
"Huff… Huff…"
Her breath caught, eyes tightly shut, Yotsuba savored the small wave of another orgasm hitting her.
"Geez, you're a hopeless pervert, Yotsuba."
Holding Yotsuba to keep her from collapsing after her umpteenth orgasm, Ren leaned down and kissed her neck.
*CHU!*
His teeth lightly grazed her sensitive skin before he sucked, leaving a clear reddish-purple hickey.
"Master, don't… I'm worried my affair will be exposed if Fuutarou sees the hickey on my neck…"
Yotsuba pleaded, trying to push Ren's head away.
"I don't care. That's your problem, Yotsuba. Figure out an excuse to deceive your husband."
"Master's bullying me."
Puffing out her cheeks, Yotsuba pouted slightly at Ren's indifference.
Their highly unconventional dinner continued.
The chopsticks in Yotsuba's hand occasionally trembled, while her body on Ren's lap kept moving up and down with his unpredictable thrusts, creating wet sounds and moans that only the two of them could hear in the dining room.
◆━⊰✧⊱━◆
After filling his stomach, Ren poured alcohol into a glass and sipped it slowly.
"Slurp…"
His eyes were fixed on Yotsuba, who was now standing at the sink, washing dishes—still completely naked.
"I want you to wear something stimulating, Yotsuba. I'm bored of fucking you naked."
Hearing Ren's sudden remark, Yotsuba turned, her face showing a panicked expression.
"M-Master! Are you bored with my body?"
"No, that's not it. Doing the same thing for too long gets tiresome for anyone. I just want some stimulation to make it more interesting."
"Thank goodness, that scared me. I thought Master was going to discard me for being boring."
Sighing in relief that Ren wasn't tired of her, Yotsuba thought for a moment, her lips pursed.
"I don't have any cosplay costumes, Master. Fuutarou never asked for them. And even my lingerie… I guess it'd seem boring to you, right?"
"Hmmm… Make sense."
Recalling Yotsuba's personality before it drastically changed into that of a slut due to the Binding Ghost's influence, Ren figured her lingerie wouldn't spark his interest.
'Yotsuba's underwear is probably plain and boring, just like what she wears when she fucks her husband, right?
"Yotsuba, use your own head to think. Don't rely on others every time there's a problem. Try solving it yourself before asking for help."
"Y-Yes, I understand, Master!"
Seeing Ren's stern expression, Yotsuba didn't dare ask further. She lowered her head, lips slightly pursed, and began thinking hard.
'What should I wear? Master wants something stimulating, but not regular lingerie, and I don't have cosplay costumes. I want him to be pleased… I want him not to get bored with me.'
'What haven't I done before? Something that'll shock and excite him at first glance.'
'What will make Master interested and want to keep fucking me?'
Yotsuba racked her brain, searching for an idea to satisfy her master's peculiar desires.
Her eyes lit up as a brilliant idea struck her. She was certain it would please Ren.
"Master, I know what to wear!"
"Good. I'm looking forward to it."
Without asking further, Ren awaited the surprise Yotsuba would present.
After finishing the dishes, Yotsuba hurried to her room, excited to put on the outfit she had in mind.
◆━⊰✧⊱━◆
Ten minutes later.
"Everything's ready. Master, please come in."
Yotsuba's voice from the bedroom called for Ren to enter.
"Oh."
With a leisurely step, Ren rose from his chair and walked toward the Uesugi couple's bedroom.
*CLICK!*
Opening the door, he saw Yotsuba now dressed.
"Oh, your high school uniform? Not a bad idea."
Before Ren stood Yotsuba, wearing her high school uniform consisting of a white shirt, green skirt, and knee-high black socks. Plus, the green ribbon shaped like bunny ears on her head, her signature look before marriage.
Of course, the school uniform barely fit Yotsuba's now fuller and more mature body.
Without a bra, the tight white shirt clearly showed the outlines of her nipples. Her skirt was so short, it barely covered her thighs, almost exposing her ass.
With a face flushed red from embarrassment, Yotsuba lowered her head slightly.
"I'm glad Master likes it."
"Then let's start the next round."
"Ready, Master ❤️."
Ren pushed Yotsuba until her back pressed against the bedroom wall, his lips ravaging hers without mercy, dominating the corners of her mouth roughly.
His hands moved quickly, finding the gap beneath Yotsuba's mini skirt, which had ridden high up her thighs. Without much effort, he found what he was looking for. His fingers breached the final barrier, dancing in the already wet area, rubbing with a rapid rhythm.
"Ah… Master…" Yotsuba moaned, her hips moving on their own, seeking more friction.
Ren lifted Yotsuba, her legs wrapping around his waist, and without removing her uniform, he positioned himself.
*PU-CHI!*
"Ahhhh~"
His first thrust was a powerful strike. Yotsuba arched and moaned, her uniform crumpled, but the sensation of the fabric against her skin during the friction added a strange thrill. Her green skirt rode up high, leaving only the knee-high black socks still in place.
*PA!* *PA!* *PA!* *PA!* *PA!* *PA!*
They moved in a wild dance. The sound of fabric rubbing, combined with the wet sounds of flesh colliding, filled the room.
Ren pulled Yotsuba's white shirt up, exposing her plump breasts, then sucked on them greedily, leaving reddish-purple marks on her fair skin.
"Mmm… Master… faster… ahh!"
Yotsuba no longer cared about her crumpled uniform or her messy hair.
Their bodies tensed, then melted into satisfying exhaustion, still connected, with Yotsuba's disheveled high school uniform as stark evidence of their brutal round.
◆━⊰✧⊱━◆
10:20 PM.
"I'm home."
Opening his front door, an exhausted Fuutarou removed his shoes. A long day at the office had drained his energy.
"Welcome back, Fuutarou."
Yotsuba's voice greeted him from the hallway. Fuutarou looked up, slightly surprised to see his wife wrapped only in a towel, her hair still wet.
"It's unusual for you to shower this late, Yotsuba."
"Oh, I just had an intense workout! I got really sweaty."
Yotsuba wasn't good at lying. Whenever she tried to hide something, those around her would immediately notice the oddity in her expression or tone.
But this time, technically, she wasn't lying. She had indeed just done some "intense exercise," just not the kind of exercise Fuutarou typically imagined.
"I see."
Fuutarou didn't doubt his wife. However, his eyes unintentionally caught a red mark the size of a finger on Yotsuba's neck.
"Are there a lot of mosquitoes in the house?"
Yotsuba instantly covered the hickey with her hand, trying hard not to panic.
"Huh? Y-Yeah! There were a lot of mosquitoes earlier, but I've put up mosquito repellent, so there shouldn't be any now."
"…"
Seeing his wife clad only in a towel, Fuutarou felt aroused.
"It's been a while since we've done it, Yotsuba. How about now?"
He stepped closer, his intentions clear.
Normally, Yotsuba would be thrilled when her husband wanted to have sex with her. But this time was different. She didn't want anyone's seed but Ren's in her womb from now on.
"Usotsuki-no-Mae."
She called the shikigami Ren had left specifically for situations like this.
*SHUA!*
The next second, a beautiful woman emerged from Yotsuba's shadow.
"What—"
Before Fuutarou could fully react, Usotsuki-no-Mae plunged him into an illusion so vivid that, in his mind, he fucked Yotsuba, their bodies entwined in burning passion.
"Phew…"
Seeing Fuutarou freeze, his gaze blank and dazed in the illusion, Yotsuba sighed in relief.
She gently caressed her still-flat stomach.
"I'm sorry, Fuutarou. I want to bear Master's child. You'll raise the child as if it were your own, right?" She whispered softly, as if her husband could hear her.
