"I never would've thought that Umi, who acts like a Yamato Nadeshiko, would wear something like this. Honestly, I feel like I'm dreaming."
Ren stepped closer, his unblinking eyes tracing every detail of Umi's appearance, which was so starkly different from her usual demeanor. His gaze was filled with desire and passion.
"I-I'm not the indecent woman you think I am, Ren-senpai! T-This is all… I learned it from the internet. I only… did it for you. W-What do you think? Do you like it?"
Umi fidgeted, her mind overwhelmed with immense embarrassment.
"Unless they're gay, no guy wouldn't like this."
Unable to hold back any longer, Ren gently lifted her downturned chin. Without another word, he closed the distance between them, pressing his lips against hers.
Umi gasped, her eyes widening briefly before they fluttered shut, surrendering to the intoxicating sensation. Her arms instinctively wrapped around Ren's neck, pulling him closer.
The kiss lingered. Slowly, without Umi realizing, her body was gently laid back onto the bed. Her mind went blank, filled only with Ren's presence surrounding her.
"Gulp…"
Umi looked so vulnerable and adorable in her provocative shrine maiden outfit. Thanks to its daring design, Ren didn't need to bother removing her clothes.
The strategically placed openings in the front and back of the hakama gave him unobstructed access. He only needed to shift the thin white fundoshi clinging to Umi's body.
Umi's face flushed deeply, her hands covering her mouth as Ren gently parted her thighs.
"Senpai… This is my first time. Please, be gentle." Her voice was thick with tension, betraying both anxiety and anticipation.
"Trust me, I'll make sure you enjoy it."
With care, Ren entered her.
"Ah~"
A stifled moan escaped Umi's lips. Her eyes squeezed shut, her small hands gripping the bedsheets. It was a sharp pain, followed by an unfamiliar warmth.
"I-It hurts, Senpai…" Umi whimpered softly.
"Hold on just a bit, Umi. It'll pass soon."
Ren paused, letting her body adjust. After a few deep breaths, Umi nodded, signaling she was ready to continue.
"C-Continue, Senpai…"
Ren began moving with a slow, gentle rhythm, watching Umi's every reaction. Gradually, the pain transformed into a new, intoxicating sensation. Umi started to respond, clinging tightly to his neck.
"Ah… Senpai… faster."
Umi's voice turned into passionate moans.
Ren grinned triumphantly. He quickened his pace, flipping Umi onto her hands and knees. In this position, the bright red hakama hung loosely, revealing her back, hips, and the beauty of her thighs.
"I love your costume, Umi. It's driving me wild." Ren whispered in her ear.
"I-If that's the case, I'm glad, Senpai…" Umi replied, her voice breaking.
Ren shifted positions again, pulling Umi to sit facing him. The revealing shrine maiden outfit made it easy for them to press close. Umi wrapped her legs around Ren's waist, holding her breath with each of his thrusts.
As their passion peaked, Umi clung tightly to Ren's shoulders.
"S-Senpai… It's my safe day… You can… release inside me."
Though still shy, Umi spoke with earnest conviction.
"Are you sure, Umi?"
"Yes… I want… I want to keep you inside me, Senpai…"
Ren grinned, surprised by her boldness.
"Don't worry, you won't get pregnant easily, Umi."
After a few strong, steady thrusts, Ren reached his climax, fulfilling Umi's request.
"Ahhh~…"
Umi let out a soft cry, her body tensing and trembling intensely before collapsing, limp in Ren's arms.
"…"
Silence enveloped the room. Umi remained in Ren's embrace, her face buried in his chest, basking in the intoxicating warmth.
◆━⊰✧⊱━◆
How could a healthy teenager like Ren be satisfied with just one round? His youthful energy and pent-up desire drove him to continue their intimacy through a third round, only stopping when Umi was utterly spent and pleaded weakly for him to stop.
"Your stamina is too much, isn't it, Senpai?"
Umi lay exhausted, using Ren's arm as a pillow. Her entire body felt boneless.
"Hey, Umi, there's something I need to talk to you about."
Ren's suddenly serious tone made Umi's heart race. An irrational fear gripped her.
"What is it?"
The worst thoughts flashed through her mind. She'd heard stories from friends about men who only wanted a girl's virginity and left once they got it. Was Ren like them?
"I don't know what you're thinking, but it's clearly not good."
Ren flicked Umi's dazed forehead with a wry smile. Then, he confessed that he had other women besides her.
"I have five other lovers, and they all live with me at home. I'm not hiding this from you because I want you to know before we go any further."
Those five were Nakano Itsuki, Maria Mikhailovna Kujou, Hayasaka Ai, Alisa Mikhailovna Kujou, and Momobami Ririka. Ren deliberately didn't mention his other women outside of them: Nakano Ichika, Nakano Miku, Nakano Yotsuba, Rita Ainsworth, Kujou Akemi, and Souo Yuki.
"What?! So, the reason Nakano-sensei took maternity leave was because of you, Ren-senpai?"
Umi was stunned by the revelation. One of them was even a teacher at their school!
Indeed, polygamy wasn't illegal in Japan at the time. Still, it wasn't easy for a woman to share her man with others. Had she known this earlier, she might not have given her virginity to Ren.
"After hearing all that, how do you feel, Umi? Regret?"
"A little…" Umi admitted honestly. "But regret is useless now. Since it's come to this, I can only accept it. You'll take responsibility, right, Senpai?"
As a conservative woman, Umi felt she now fully belonged to Ren. There was no turning back.
"Of course. No way I'd let you go." Ren promised, kissing Umi's lips gently.
"The problem is my parents… I'm worried they won't accept our relationship."
Umi's concern was reasonable. What parents would want their daughter to be part of a man's harem?
"Leave convincing your parents to me. I guarantee they'll approve."
"Mm. I trust you, Senpai."
What Umi didn't know was that Ren's method of "convincing" wasn't through discussion or negotiation but through hypnosis.
Why take the hard way when there's an easy one?
"Umi, let's do it again."
"No way. I'm exhausted, Senpai. Next time." Umi refused, hiding her flushed face in Ren's chest.
Ren smiled faintly. "Come on, Umi. Didn't you say you wanted to keep me inside you longer? It's your safe day, right?"
His cheesy persuasion, paired with a naughty touch on her hips, quickly broke Umi's defenses.
"Ugh… Ren-senpai, that's unfair!" Umi complained, but she lifted her head, her eyes filled with barely concealed passion. "Fine… just for a bit."
Persuaded, Umi agreed to indulge him once more, and she soon regretted it.
Once? That was nowhere near enough for a Campione with boundless stamina!
Ren flipped Umi onto her knees on the bed, positioning himself behind her. The provocative shrine maiden outfit she wore made everything easier. In this embarrassing position, Ren joined their bodies again.
"You look so beautiful like this, Umi."
"D-Don't look, Senpai… It's embarrassing…" Umi shut her eyes tightly but didn't resist. Her hands gripped the pillow, her body swaying with Ren's strong, deep movements.
After a while in that position, Ren pulled Umi to lie on her side facing him, her legs wrapping around his waist. Their eyes locked, Umi's glistening with overwhelming pleasure. Their kisses grew greedy, Umi's breaths ragged.
"Senpai… I-I can't take it anymore…"
But Ren didn't stop. He flipped Umi onto her back, positioning himself above her. He gazed at her flushed, sweaty face, lifting her legs to his shoulders—a position that exposed her vulnerability and allowed deeper penetration.
"Hold on a bit longer, Umi. I'll make you feel so good you'll forget your own name."
Waves of pleasure flooded Umi. Her moans grew louder, shattering the silence of the house. She bit her lower lip, begging Ren to stop yet pleading for more.
"I give up, Ren-senpai… I'm yours…"
Only when Umi was utterly exhausted, her body unable to hold itself up, did Ren stop. He lay beside her, satisfied.
Meanwhile, Umi collapsed, drained of energy, but a faint smile curved her lips—a smile of a woman completely conquered.
