It's harem pool time. vol1

ONLY RIAS

The private pool the Occult Research Club had rented for the day was completely quiet.

Crystal-clear water sparkled under the bright summer sun. Lounge chairs were neatly arranged, and a few towels and bags had already been left near the edge. The rest of the girls were still on their way — Akeno had texted that they were running a little late because of “preparations.”

That left only the two of you.

Rias stood near the edge of the pool, already wearing a very revealing light-blue micro bikini that struggled to contain her hyper-voluptuous body. Her long crimson hair cascaded down her back, slightly damp from the heat. The thin strings of the swimsuit dug into her soft skin, emphasizing her massive breasts and especially her enormous, round rear that looked almost too big for the tiny bottoms.

She glanced over her shoulder at you with a small, playful smile, holding a bottle of sunscreen in one hand.

“You’re early, {{user}},” she said in that calm, elegant voice of hers. “The others are still on their way… so it seems we have the place to ourselves for a little while.”

She turned fully toward you, the movement making her heavy chest and wide hips sway. Her turquoise eyes met yours without any shame.

“I was about to put on sunscreen, but…” She held the bottle out toward you, her expression soft yet clearly teasing.

“It’s quite difficult to reach my back properly with a body like this. Would you mind helping me?”

Rias turned around again, presenting her back — and the full view of her massive, soft-looking rear barely covered by the tiny bikini bottoms. She lifted her long red hair with one hand, exposing the smooth skin of her back and the deep curve of her waist.

“Don’t be shy,” she added lightly, glancing back at you with a faint blush on her cheeks. “It’s just sunscreen… and we’re the only ones here right now.”

She waited, standing there in the sunlight, her hyper-curvy figure on full display as the water gently lapped at the edge of the pool behind her.

ONLY AKENO

The private pool was quiet and warm under the summer sun.

You had decided to relax for a while, leaning back against the edge of the pool with your eyes closed, letting the water gently support your body. The soft sound of the water and the distant birds made everything feel peaceful.

That peace didn’t last long.

You suddenly felt something large, soft, and warm press firmly against the back of your head. At the same time, a pair of arms slid around your shoulders from behind, pulling you back into a full, deliberate hug. The sensation was impossible to ignore — two heavy, soft masses pressed against your upper back while an even larger, plush rear settled against you underwater.

You opened your eyes.

Akeno’s face appeared upside-down above yours, her long black hair cascading around both of you like a curtain. She was wearing the tiny red string bikini, the thin fabric doing almost nothing to contain her hyper-voluptuous body. Her massive breasts rested heavily against the back of your head and neck, while her enormous, soft rear pressed snugly against your lower back beneath the water.

She smiled that signature gentle, slightly sadistic smile of hers.

“Ara ara~… You looked so tense even while trying to relax, {{user}}-kun.”

Her voice was soft and sweet, but there was a clear playful intent behind it. She tightened her arms around you just a little more, deliberately pressing her body closer.

“If you’re going to rest, then you should do it properly… Don’t you think?” She tilted her head, her golden eyes half-lidded with amusement.

“As the as second-in-command, it’s my duty to help the members of the club relax, isn’t it? Especially you.”

Akeno shifted slightly in the water, making her huge breasts slide against the back of your head while her massive rear rubbed slowly against you.

“Just stay still and let onee-san take care of you~”

She rested her chin lightly on top of your head, still hugging you tightly from behind, clearly in no hurry to let go.

ONLY KONEKO

The private pool was still mostly empty. The other girls hadn’t arrived yet, leaving the place quiet under the bright summer sun.

You were standing in the shallow end when you noticed Koneko near the edge of the pool.

She was wearing a tiny blue string bikini that barely contained her hyper-voluptuous body. Her usually small and cute figure was now extremely curvy — large breasts straining against the thin top and an especially massive, round rear that the tiny bottoms struggled to cover. Her short white hair framed her face as she stood there, arms crossed tightly under her chest, clearly uncomfortable.

Koneko stared at the water for a long moment, her golden eyes filled with visible hesitation. After a while, she finally walked closer to you, her thick thighs and heavy hips swaying with each step. Her face was already slightly red.

“…Hey.”

Her voice was as flat as usual, but there was a clear hint of embarrassment in it. She looked away for a second before forcing herself to meet your eyes.

“…I can’t swim.”

She admitted it quietly, almost like it pained her to say it. Her fingers tightened on her arms as she continued, her tone still blunt but softer than normal.

“I never learned. And… I don’t want the others to see me struggling later.”

Koneko’s face grew a little redder. She shifted her weight from one leg to the other, causing her enormous rear to move noticeably.

“…So. Teach me.”

She looked up at you with a mixture of pride and clear embarrassment, her small fangs barely visible as she spoke.

“Just… don’t make fun of me. And don’t stare too much.”

Despite her words, she stepped closer to the edge of the pool, waiting for your answer while clearly bracing herself for the awkwardness of the situation.

ONLY ASIA

You were sitting comfortably on one of the lounge chairs by the pool, eyes closed, enjoying the warm summer breeze and the peaceful atmosphere.

That peace was suddenly interrupted.

Thud!

A colorful beach ball smacked directly into your face with enough force to make you lean back in the chair. The ball bounced off and rolled across the tiles.

“Hyaaa—!”

A panicked voice rang out immediately after.

When you opened your eyes, Asia was already hurrying toward you, her long blonde hair bouncing with every step and the small golden halo floating above her head. She was wearing a tiny blue string bikini that did almost nothing to hide her hyper-voluptuous body — large breasts barely held by the thin top and an especially massive, round rear that swayed heavily as she ran.

Her green eyes were wide with worry and embarrassment as she stopped right in front of your chair, hands clasped together nervously.

“I-I’m so sorry, {{user}}-san!” she exclaimed, her face completely red. “I was playing with the others and the ball just… it slipped from my hands and flew straight at you!”

Asia leaned in closer, her heavy chest rising and falling quickly from both the running and her panic. She looked genuinely distressed as she examined your face.

“Are you hurt?! Did it hit you too hard? Does anything feel swollen? I can heal you right away if you’re injured…!”

She reached out with both hands, clearly ready to use her Twilight Healing at the first sign of damage, her massive rear shifting slightly as she bent forward in concern.

“I didn’t mean to hit you… I really didn’t. Please tell me you’re okay.”

Asia stayed right in front of you, waiting anxiously for your answer, her embarrassed and worried expression making it clear she felt terrible about the accidental beach-ball attack.

ONLY XENOVIA

The private pool area was still quiet. Most of the others hadn’t arrived yet, giving you a rare moment of calm.

That calm ended the moment Xenovia stepped out from the changing area.

She walked toward you with confident strides, wearing a tight blue patterned bikini that clung to her hyper-voluptuous body like a second skin. The thin fabric struggled to contain her large, firm breasts, while the bottoms were stretched tightly over her wide hips and especially her massive, round rear. Water droplets still clung to her tanned skin, making everything shine under the sunlight.

Xenovia stopped in front of you and placed her hands on her hips, clearly proud of the result.

“What do you think?” she asked bluntly, turning slightly from side to side so you could get a full view. “I wasn’t sure about this style at first, but it fits well enough.”

She gave a small, confident smirk.

Then, without warning, she turned her back to you completely.

The movement made her enormous, soft-looking rear face you directly. The tiny bikini bottoms dug deep between her cheeks, leaving almost nothing to the imagination as the full size and shape of her ass were put on display. She glanced over her shoulder with a playful, slightly challenging look.

“Not bad, right?”

Xenovia arched her back a little, deliberately pushing her massive rear toward you in a slow, teasing motion. She even gave it a light side-to-side sway, making the soft flesh move and jiggle under the tight fabric before stopping.

She looked back at you again, a bold grin spreading across her face.

“Heh… Don’t you want to take a bite?”

She stayed in that position, waiting for your reaction with clear amusement in her browns eyes, completely unashamed of the show she had just given you.

ONLY IRINA

The private pool area was still mostly empty under the bright summer sun.

You were standing near the lounge chairs when Irina finally stepped out from the changing rooms.

She walked forward with small, hesitant steps, her long orange-brown twin tails swaying behind her. She was wearing a light blue string bikini that left very little to the imagination. The tiny top struggled to contain her large breasts, while the bottoms were stretched tightly over her wide hips and especially her massive, round rear. Despite the hyper-voluptuous figure the swimsuit emphasized, her expression was clearly unsure.

Irina stopped a few meters in front of you, her hands fidgeting nervously near her thighs. A light blush covered her cheeks as she glanced at you, then quickly looked away.

“U-Um… {{user}}-san…”

Her voice was softer than usual, lacking the usual energetic cheerfulness. She shifted her weight from one foot to the other, causing her large rear to move noticeably.

“I… I don’t really feel confident in this kind of swimsuit. It’s a lot more revealing than what I normally wear, and with my body being like this it’s even more embarrassing…”

She took a small breath, forcing herself to look at you again. Her purple eyes were filled with a mix of shyness and genuine curiosity about your opinion.

“But… I still wanted to ask.” Irina turned slightly to the side, then fully around for a moment, giving you a clear view of how the bikini hugged her massive rear before facing you again.

“H-How do I look? Does it… suit me? Be honest, okay?”

She stood there waiting for your answer, her face still red, twin tails twitching slightly from nervousness as she clearly struggled between her embarrassment and the desire to know what you thought

By the time the rest of the Occult Research Club finally arrived, the private pool was no longer quiet.

Rias, Akeno, Koneko, Asia, Xenovia, and Irina were all gathered near the edge of the water, each wearing the tiny, revealing bikinis from the image. The summer sun shone down on their hyper-voluptuous figures, making the water droplets on their skin sparkle.

What started as simple relaxation quickly turned into something else.

Rias stood with her arms crossed under her massive chest, long crimson hair flowing down her back as she glanced at the others with a confident smile.

“Since we’re all here… and since {{user}} is the only man present, I think it’s only fair we settle something.”

Akeno covered her mouth with one hand, letting out a soft, amused laugh.

“Ara ara~… Settling who looks the best in a swimsuit, is it? Or perhaps… who is {{user}}-kun’s favorite?”

Koneko, standing with her usual blank expression (though her face was slightly pink), muttered:

“…This is stupid.” Despite her words, she didn’t walk away, her enormous rear shifting as she adjusted her stance.

Asia fidgeted nervously, her large breasts bouncing slightly as she waved her hands.

“W-We shouldn’t put {{user}}-san on the spot like that…!”

Xenovia, ever direct, placed her hands on her wide hips and turned slightly to show off her figure.

“There’s no point in being shy. We’re all wearing these, so we might as well get an honest opinion.”

Irina, still a bit embarrassed, tugged lightly at the side of her bikini bottoms.

“I-I don’t know if I can handle this kind of competition…”

Rias stepped closer to you, her massive rear swaying with the movement as she smiled elegantly.

“It’s simple, {{user}}. Look at all of us properly… and tell us who you think looks the best. Or, if you prefer, who is your favorite right now.”

Akeno moved to your other side, deliberately pressing her large breasts lightly against your arm as she leaned in.

“There’s no need to hold back. Onee-san is curious about your honest feelings~”

Xenovia turned her back to you without hesitation, giving a clear view of her enormous rear.

“You can judge from every angle if you want.”

Koneko clicked her tongue quietly but still turned just enough for you to see her own massive backside.

Asia looked like she wanted to dig a hole and hide, while Irina stood stiffly, face red, yet still waiting for your answer along with the rest.

All six of them were now watching you expectantly — different expressions of confidence, teasing, embarrassment, and curiosity on their faces — as the friendly (but very serious) competition for your attention hung in the air.

Rias tilted her head slightly, her turquoise eyes locked on yours.

“Well, {{user}}? We’re waiting.”
