"I-Ichika?! What's with that swimsuit? Why didn't you pick a normal one?!"
Itsuki exclaimed in shock, her eyes widening in disbelief as Ichika appeared in her minimal white slingshot swimsuit.
In her opinion, with a man present—even if Ren was her brother-in-law—it was inappropriate for Ichika to wear something so revealing.
"Oh, Itsuki, you're saying something hilarious." Ichika replied with a faint smile, unwilling to take the blame for a choice that wasn't truly hers. "Let me ask you, Itsuki, is there such a thing as a 'normal' swimsuit in this house?"
"Ugh…"
Itsuki fell silent, reflecting on the contents of the swimsuit wardrobe. She couldn't argue.
Every swimsuit in the residence was bought and chosen by Ren himself, tailored to his depraved preferences that knew almost no bounds.
"Sorry for yelling at you, Ichika." Itsuki finally apologized, her expression softening slightly. "But… don't you mind wearing a swimsuit like that?"
Her gaze couldn't help but linger on the details left uncovered by Ichika's white slingshot swimsuit.
Her gaze fell on the areolas that weren't completely covered by the skimpy fabric, and the bulge in Ichika's chest that was clearly visible beneath her slingshot swimsuit. Down below, the dense black forest at Ichika's crotch is also clearly visible.
"I don't mind at all." Ichika said, still smiling, waving her hand as if it were trivial. "Besides, there are no outsiders here, right? We're all family."
She seemed completely unbothered by her provocative appearance.
"If you say so…" Itsuki sighed, slightly relieved to see her sister so unfazed.
Her gaze then shifted to Ren, who was still lounging casually in his folding chair. Itsuki was mildly surprised that her usually depraved husband didn't show an exaggerated reaction, not ogling Ichika as she might have expected.
(Hubby wouldn't be interested in his sister-in-law, right?) Itsuki thought doubtfully to herself.
What she didn't know was that her husband had long extended his sinful hands to two of her other sisters.
Not to mention Yotsuba, who was now completely submissive and obedient as Ren's slave, thanks to a supernatural event that transformed her. And while Miku hadn't yet crossed physical boundaries with Ren, it was only a matter of time.
If Itsuki found out about the betrayal-that Ren had fucked her own twin sister-without the intervention of the supernatural powers that usually tempered her emotions, she would most likely experience severe contractions and end up miscarrying.
Not wanting to control Itsuki's mind as he did with Masha and Alya, Ren kept all his affairs with Itsuki's sisters a secret.
"I'm a bit tired. Hubby, I want to rest inside and won't continue swimming." Itsuki said, holding her round belly, swollen from the seed of her student.
"Ririka, help Itsuki. Be careful she doesn't fall." Ren ordered immediately.
"Y-Yes, Ren-sama."
Emerging from the pool and approaching Itsuki, Ririka supported the pregnant woman, helping her walk slowly toward the house's entrance.
"Well then, I'll start warming up before swimming to avoid cramps."
Ichika stood at the pool's edge, facing Ren, and began her stretches. As she bent forward to touch her toes, her full breasts bounced softly within the minimal white slingshot swimsuit, nearly fully exposed.
When Ichika stretched her arms upward, the swimsuit pulled slightly, accentuating her narrow hips and toned, flat stomach. Every movement, though intended as a warm-up, looked intensely sensual, as if she were dancing solely for Ren's gaze.
(Is Ichika deliberately teasing me?)
Noticing Ichika's behavior went beyond a typical warm-up, Ren narrowed his eyes, still half-closed behind his sunglasses. A faint smirk appeared at the corner of his lips.
Meanwhile, Ichika turned to face the pool, now showing her entire backside to Ren. She continued her warm-up, bending deeply to stretch her back and legs.
As her body arched downward, the white slingshot swimsuit pulled tight against her skin. Her smooth, round buttocks were fully exposed, completely unconcealed. Even without the sharp vision of a Campione, Ren could clearly see the faint outline of the national actress's anus as the thin swimsuit fabric creased and slightly tucked into her cleft when she bent over.
The sight was so explicit, a wordless invitation.
(This woman… Isn't she worried Itsuki will find out if Masha and Alya tell her?)
If Ren had been uncertain before, he was now convinced Ichika was blatantly seducing him. Her actions were too overt to be misinterpreted.
(Ichika knows I wouldn't dare do anything to her right now, which is why she's so bold…)
Ren understood her intentions. Though depraved, his self-control was impressive. He wouldn't lose his reason over this temptation. He knew there were boundaries he shouldn't cross, at least for now.
Worse still, while Masha and Alya were distracted and not paying attention, Ichika added several highly provocative movements to her warm-up.
Her right hand moved back and forth near her slightly open mouth, her tongue sticking out as if licking something invisible. At the same time, Ichika swayed her hips up and down in provocative circular motions.
Then, Ichika suddenly arched her back, thrusting her hips forward as if rhythmically pushing in the air, before returning to her original position with a mysterious smile on her lips.
All these movements were timed perfectly, visible only to Ren.
Turning back, Ichika glanced at Ren once more. She placed an index finger to her lips, signaling that it should remain their little secret.
With a satisfied smile, Ichika dove into the pool, her body gliding smoothly into the cool water. She began swimming freestyle, occasionally glancing at Ren.
"Ren-sama, I brought snacks."
Hayasaka's soft voice sounded as she approached, carrying a tray of snacks and cold drinks.
"Perfect timing, Ai." Ren said with a faint smile, channeling the pent-up desire Ichika had stirred.
"Huh?"
Before Hayasaka could grasp what her master meant, she felt a strong pull. In an instant, she was in Ren's arms, his lips pressing roughly against hers.
"…?!"
Recovering from her shock, Hayasaka proactively returned the kiss. Her arms wrapped tightly around Ren's neck, pulling him closer, as if oblivious to their surroundings.
"…"
"My goodness, doing it in front of everyone… This is Ren-kun's retaliation, isn't it?"
Ichika's eyes widened from the water, watching Ren and Hayasaka make out passionately on the lounge chair without a hint of shame.
Ren gripped Hayasaka's waist tightly, pulling her onto his lap, their tongues clashing in an increasingly deep and wet kiss.
Ren's hands, initially on Hayasaka's waist, began creeping downward, slowly slipping inside her bathrobe, causing the fabric to shift and reveal her smooth thighs.
*PA!* *PA!* *PA!* *PA!* *PA!*
Then, Hayasaka began moving. Her body subtly rose and fell rhythmically on Ren's lap, a faint but clear indication of activity beneath the bathrobe.
*PA!* *PA!* *PA!* *PA!* *PA!*
The loose robe swayed slightly with each gentle thrust from Hayasaka, creating a passionate scene despite being partially concealed.
*PA!* *PA!* *PA!* *PA!* *PA!*
Ren occasionally thrust his hips upward, emphasizing the rhythm, while their kiss remained unbroken.
"My goodness, doing it in front of everyone… This is Ren-kun's retaliation, isn't it?"
Ichika's eyes widened in the water, watching Ren and Hayasaka make out passionately on the lounge chair without a hint of shame.
What shocked her more was that, although Masha and Alya blushed slightly at the outdoor sex scene, they didn't seem surprised at all.
More accurately, they were already accustomed to such sights at the Rokuhara Residence.
Only Ichika, still a virgin, felt overwhelming embarrassment. Yet, curiosity—and something else—kept her from looking away.
