Perfect

You really shouldn’t have been surprised that the apartment complex inhabited by the biggest girl group in the country would have a luxurious indoor pool. 

You were nonetheless still surprised by the scale of it - taking up almost the entirety of one of the lower floors and equipped with the latest in modern decor and furnishings, you couldn’t help but feel a little out of place amidst the lavish display of wealth you suddenly found yourself surrounded by.

But you were also dating one of the most popular, most desired women in the country - you should have been used to it by now.

And so you are content to float on your back in the shallow end of the massive pool, relishing the weightlessness that it gave your tired body. You weren’t one to complain about the content of the birthday presents that Mina had lined up for you - being given a turn with a couple of her groupmates was surely beyond the wildest dreams of any man on earth, and your sessions with Nayeon and Momo had certainly left you more than a little sore and worn out.

You float towards the edge of the pool near the steps and drape your arms over the edge, leaning back and letting your legs float weightlessly in front of you. Your eyes drift closed, and for a moment you consider sneaking in a short nap, perhaps on one of the many comfy looking lounge chairs that filled the poolside deck.

Your plans are interrupted by a sweet, soft greeting.

“Happy Birthday!” comes the voice, and you know even without looking that Minatozaki Sana has entered the pool.

You turn your head to watch as she appears from behind the heavy, card-locked entrance to the pool, wrapped in a head-to-toe robe of white cotton. On her soft, beautiful features is the ever-present smile that you’d come to know well in the past several years.

You were of course no stranger to the members of Mina’s group, although your relationship with most of them had begun and ended with the awkward greetings and farewells exchanged whenever you were picking up or dropping off your girlfriend. Sana was the outlier - she was every bit as extroverted and friendly as the persona she exuded on TV, and she quickly became a friendly face whenever you visited Mina’s dorm. She had even accompanied you and Mina on several outings, her natural friendliness and outgoing demeanor ensuring that such occurrences rarely felt awkward or weird. She was one of the few girls in the group you actually talked to outside of your rare outings with the girls - it gave you no small amount of pride to say that you counted her as a friend.

“Thank you,” you answer with a friendly smile as she approaches you. She pulls up one of the reclining lounge chairs to the pool edge and sits on it, looking a little like a bunny rabbit in her fluffy white robe.

“I hear you’ve had quite the evening already,” she says, with a teasing tone. “I’m surprised you could still walk all the way over here on your own.”

You couldn’t help but let a sly smile appear on your lips. Had the evening ended with you and Mina having a private session in the karaoke room she’d reserved, you would’ve been more than content. You could never in a million years have expected this evening to have gone the way it had.

“I suppose,” you answer, not quite knowing how to respond. 

“First Mina, then Nayeon, and then Momo… you must be the luckiest guy on earth,” Sana says, as if reading your mind.

“Definitely.”

Sana lets her gaze wander, her eyes looking out over the glimmering crystal blue of the pool. Hesitantly, you turn your face to look up at her to find a slim, sly smile on her lips. She looks down at you, face bright and friendly, as it always was.

“Did Mina tell you that you get to fuck me next?”

You experience a sudden bout of panic at her question - after a quick shower in their dorm to clean up after your session with Momo, Mina had sent you to the pool without any further instruction, where she insisted you would receive the next part of your present. If Mina had arranged for Sana to be here, then that could only mean that…

“Uh, no, she just, uh, she sent me down here, and-”

Sana giggles. A soft, musical sound. Sana had always seemed to live on a plane of existence unique to her, like a fairy in a land where only wonders and happiness existed - even when she was talking about more carnal topics.

“Don’t worry about it, silly,” she says in that soft, sing-song tone of hers. “We both know why I’m here. It’s your birthday, after all,” she adds, with a bright smile wide on her lips that belied the lewd content of her words and the implication they carried.

Without a further word Sana rises from the lounge chair. You watch as her fingers quickly undo the belt of her bathrobe, which quickly falls from her body to become a pool of white cotton at her feet.

Even fully clothed and on stage, there was no hiding the wondrous body Minatozaki Sana hid beneath the layers of cotton, silk, or lace that made up her many stage outfits. With her long, curvy figure and perfect proportions she seemed sculpted from the collective desires of every man in the country - as though she had stepped out of a video game or an anime, impossibly perfect body and all. 

But here, now, in nothing more than a skimpy white bikini top and matching thong, she was utterly sublime.

She gives you only a moment to admire her body - a moment that you wish could have dragged on for longer than it did - before she takes the steps from the edge of the pool and into the waist-high water.

Your breath catches in your throat, and for a moment you had to physically remind yourself to breathe. You’d been around more than your fair share of beautiful women that evening - Nayeon was probably one of the most sexually attractive women on the planet, and Momo had one of the most perfectly fit bodies you’d ever seen - but Sana gave them both a run for their money. She had Momo’s fitness and Nayeon’s sexuality, all topped with a face that sometimes seemed drawn by the hand of an artist. With her large eyes and soft, cute features above a body that seemed built for sin, Sana was at once both disarmingly adorable and dangerously sexy.

Only Mina could top her.

Sana dips below the water before she emerges from beneath it like some goddess of antiquity, eyes closed, her slightly wavy hair now matted against her perfect skin. She takes a moment to brush the wet strands back from her face with both her hands, giving you a perfect view of her upper body and the round, perfectly shaped breasts held in the cups of her bikini top. The water dripping down her body only amplified the raw sexuality pouring from every inch of her, making her somehow even more irresistible than she already was.

She knows you are watching her, knows you are drinking in the sight of her wet, tight body like a thirsty man slurps up water. She takes her time as she brushes the hair back from her face, gathering it behind her head before draping it over one shoulder, eyes still softly closed. There is a hint of a smile on her lips as though she is bathing in your attention, letting it wash over her just as much as the pool water now was. 

She could have emerged from the water facing away, but she very obviously chose to do so while facing you, ensuring you had a perfect view of her body. She wanted to give you a show, a taste of what was to come. She knew what she was doing.

Minatozaki Sana always, always knew what she was doing.

She floats softly towards the edge of the pool and leans against the wall next to you, upper body above the waterline, propping herself up with her elbows on the pool edge just as you were. It took every ounce of self-control you had in you to keep from turning to watch the water drip down her wet torso.

“You seem…nervous,” she says, playfully, and you turn to find that she has fixated you with an adorable, curious look with those large round eyes of hers that almost takes your breath away. How could someone seem so cute and innocent and dangerously sexy at the same time?

“I, uh,” you begin, awkwardly. “I… I dunno, isn’t this kinda weird, Sana?”

The girl giggles, hiding her laugh with a hand at her mouth. “It is, a little,” she admits. “I mean, when your girlfriend asks you to fuck her boyfriend as a part of his birthday present, it’s not exactly an everyday conversation.”

“Yeah,” you agree, “I don’t really know Nayeon or Momo that well, so it wasn’t super awkward with them, but with us… we’re…”

“Friends?” Sana asks, and you turn your head to find her eyes fixed on yours, a warm smile on her lips.

“Yeah,” you admit.

“Would you rather that we didn’t fuck?”

“No, I mean, I just, uh, I… I don’t want it to be weird. We don’t have to do this.”

Sana inches a little closer to you on the pool wall before she leans her head towards your ear.

“It’s only weird if you make it weird,” she says, softly, her tone carrying just a hint of allure that wasn’t there before. “Just relax… and enjoy your birthday present.”

Her left hand reaches up to your chin, steering your face gently towards hers. You have only a moment to notice the sensual smile on her lips before she presses them against yours.

The kiss is soft, gentle - almost as soft as those you shared with Mina - but there is an underlying desire there, simmering just below the surface. Her tongue is first to press against your lips, sliding across them before slipping between, finding and engaging your tongue in an intimate, slick dance as her hands wrap themselves around your neck and shoulders. 

As you continue to kiss, her left hand disappears below the water line, where she slips her hand into the loose waistband of your swimming trunks. Her fingers quickly find your rapidly hardening length, wrapping her fingers around it, giving it a few slow, soft strokes - and you feel a soft shiver course throughout your body as the first delicious spikes of pleasure make their way up your spine and into your brain.

She breaks the kiss, leaving you face to face with her. Beneath the water, her hand wraps a little tighter around your almost completely stiff shaft.

“You know, I think about you a lot,” she says, softly - words that cause your heart to flutter more than you’d cared to admit.

“...Yeah?” you answer, breathlessly. Her hand on your cock had managed to steal all the breath from your lungs, and gathering the oxygen needed to speak had suddenly become difficult.

“Mina talks about you a lot, of course,” she begins, with a cute, shy glance away from you, an adorable look that seemed utterly out of place given the very naughty things she was doing just beneath the waterline. “And she gets me thinking… about what you two do. Dirty things. Like… how big you are. And the way you fuck her. The way you fill her up and make her feel so full. And the way… she chokes on your cock sometimes when you fuck her mouth, or the way you fold her in half and fuck her so deep you basically hit her stomach.”

“Jesus, Sana,” you swear. You were fully stiff now, and the pace with which she was pumping her hand around your shaft had quickened into a steady but firm pace.
