A Girl At Guys Night

The exposition goes swimmingly

"So, your little sister is eighteen now..." Jeff drips onto the pavement as he tilts back his beer, the two of us plodding back around for another dive.

"Ya..." I frown at his smirk as he sets down the drink and steps onto the diving board.

"So you won't mind if I..." He shakes his head side to side and gives me a moment to think it over as he dives in.

Jeff and I both got into state on swim team, so he's built a lot like me: broad shoulders, sleek muscles. It's not like he wouldn't have a chance, even if June hadn't had a crush on him ever since she met him three years ago. Plus, Jeff's parents split up when he finished high school, so since he didn't really have a home to go to, he's staying with us for the long weekend anyways. He'll have plenty of opportunity.

"I don't tell my sister who to sleep with." I say bluntly as he surfaces across the pool and I spring off. I back out of the flip at the last second and manage to recover into a more or less gentle dive.

Not that there was much to object to on that front. You'd expect her to have her pick of the litter with her modest-sized but practically anti-gravity tits, and ass cheeks like looked like they feel like mochi they way they hang out of her shorts, and... well, as you can tell, even I've caught myself need to 'adjust' around her. But she's only had maybe two boyfriends since she started high school, as far as I've been aware. Or even things vaguely like a boyfriend. I blame social media.

"I just wanna know you won't get all butt hurt when I hit that is all." Jeff doesn't even wait for me to breathe as I surface.

"You have my blessing to bang my little sister." I shrug. "But you can't get her drunk, not cool."

Jeff smacks me brusquely on the back, "Challenge accepted!" His eyes catch movement and he turns to scan the windows of the house, "Speak of the devil!" He grins.

"Hey guys!" June comes out smiling, home from school. Her dirty blonde hair characteristically hooked behind one ear, the hem of her black crop top t-shirt dangles off the afore-mentioned anti-gravity breasts, and I can't see it from here, but I'm 90% certain these are those jeans she has that actually seem to scoop up her butt cheeks in the back. Jeggings or something. Like magic.

"Hey June!" Jeff pulls himself up and out on the side of the pool, making an obvious attempt to accentuate his arms, and from June's pursed lips, it works. "You look... incredible." Jeff walks up to her, appreciating her figure. I would've expected her to be a little put off by his leering, but she just blushes at the attention. "You should join us in the pool!"

"Maybe I will! I'll go get changed..." She glances at me and smiles and starts to turn, but hesitates as Jeff reaches out. She looks at his hand grasping hers.

"Just jump in, c'mon, it'll be fun." He grins, starting toward the diving board with her in tow and I try not to roll my eyes too loudly from the water.

"Oh, I don't know, I mean, I don't want to get this bra wet..." Her eyes dart to me again and she tries to pull away, but he slips his hand up her arm, not grabbing her, but running his fingers along her skin, gently, and she pauses again.

"Then take it off." He shrugs. "C'mon, we're only in town for the weekend, let's have a little fun!"

She looks over at me directly this time, pausing as if to ask permission to, what, fuck my buddy? I shrug at her like I shrugged at him. Why does anyone need my permission to fuck?

"Um, ya, okay..." She bites her lip, reaching back, sticking out those tits as she pops them free. In a moment, the bra is tossed aside, along with her shoes, and she's shimmying off the tight jeans.

I eye her skimpy white panties with the bright red heart and shake my head, trying not to think too hard about what they'll look like after she jumps in.

"Let's fuckin' go!" Jeff smacks her on the ass and she jumps with a happy shriek, scurrying over to the diving board. He gives me a look.

Jesus. This weekend just got fucking rough.

"Okay, um, here I go!" June bounces along to the end of the diving board, hesitates briefly, then hops off, feet splayed awkwardly in front of her.

She's not much of a diver.

She surfaces with a gasp and a quiet squeak, hurrying to tug her top down, a flash of flesh barely more than a pair of handfuls, all but censored by the still-rough water of her splash. "Oh, it's so warm!" She swallows, trying not to acknowledge the fact that her tits just very much popped out as she paddles toward me at the side of the pool.

"That wasn't a dive!" Jeff shouts, "This is a dive!" He dashes down the board and does an excellent flip, smoothly slipping under the water.

"Why can't you do that?" June smacks my arm, my eyes trying desperately not to stare at the way that shirt is clinging to the curves of her otherwise bare breasts, the way the water accentuates their already gravity-defying perk.

"I mean, I could." I shrug, "Why can't you dive like a normal person?"

"Uh!" She half pouts, half laughs, "I could if I wanted to too!" Her face makes that curved smile she does, as if daring me to prove I can flip.

"Sweet flip, eh guys?" Jeff surfaces up next to us, and it briefly occurs to me he might've missed the best part of June's jump from outside the water.

"He says he can do better." June mocks, propping her arms behind her, turning toward the pool, sticking her chest out toward Jeff, the soaked black shirt clinging tightly, her nipples now plainly dangling just above the water's surface.

"No, I said you can't even dive." I try once again to look anywhere but at my sister's tits.

"How about you show us your flip and you can show me your dive?" Jeff smiles at June, who smiles back.

"Ya, show us your flip, if you're so hot," June doesn't even look away from Jeff as he sidles up next to her. I take the hint and drag my third wheel out of the water.

"Ya, sure, no problem." I casually adjust myself as I climb the steps, grabbing my beer and taking a long swig before splashing wet footprints around the pool to the diving board.

"Let's see those skills, yo!" Jeff says, casually sliding up alongside my sister at the edge of the pool. Not quite daring enough to slip his arm around her, but daring enough to be within reach.

"I believe in you, big bro!" June's voice is disconcertingly earnest as I speed down the board.

I catch a good footing this time, much better than it felt last jump, and push some power in. It connects, but it's too much, and I slap my shoulders into the water.

Fuck, that's gonna sting in a minute.

I glance toward the two of them under the water as I curve over their way, and notice June's panties. Or rather, barely notice them. In the fog of seeing under water, I can't make out details, but I can definitely see a red blur where the heart is, and nothing but a soft blonde blur and skin tone around it.

I surface beside June, opposite Jeff, and murmur in her ear, "Hey, sis, your panties..."

She looks quickly at me, immediately realizing what I'm hinting at. I'm quiet enough that Jeff remains oblivious.

"Does that count?" He tsks and June looks nervously at me. I just shrug at her. I don't know what to do. If she gets out...

June seems to consider briefly, then smiles, biting her lip, and mouths silently to me. "Do you care?"

I glance at Jeff, then at her, and shrug. Jeff seems to imagine it's directed at him.

"I think it counts." June speaks up, then turns to Jeff. "Now you two can judge my diving skills!" She pushes away from the wall and paddles over to the steps.

"Holy hell..." Jeff mutters as she starts drawing up out of the water and her transparent panties become visible. My sister's round cheeks are nearly bare as she walks up the steps, water pouring off her, dripping in little rivulets from her clinging short t-shirt.

"These, uh, panties, got a little..." She cups her hands in front of her crotch as steps out of the pool, turning toward us and the board. "See through..."

"I don't mind!" Jeff offers as she walks by.

It's a little disappointing that her shirt clings so tightly to her breasts and we can't see up from this angle, but damn if those tits don't look incredible as she walks.

What am I saying?!

I try to look away as she steps up to the edge of the diving board, squatting, arms still covering her crotch.

"You gotta, you can just roll in, but, you gotta put your arms out, like this!" Jeff gestures his arms forward, and June looks nervously down at us. I try, and fail, to look anywhere but between her legs as she pulls her hands free.

"Ah!" Encouraged probably by her desire not to have that little blonde triangle and the shockingly smooth lips below it bared to us for too terribly long, the tight white cotton completely transparent where it clings snugly to her skin, the slit between those two lips tantalizingly hidden by a defiant patch of opacity where the fabric pulls away, only serving to accentuate the shape of those lips...

Stop it!

She curls forward, plummeting more than diving into the water, but managing to do so head first at least. Not much of a diver, as I said.

"Fuck your sister is hot as fuck, dude." Jeff blurts while she's under.

"Oh my god..." June gasps, panicked, as she surfaces. Seemingly on instinct from years of watching my little sister learn to swim, I bolt out beside her, scooping her into one arm, treading water with the other.

"Are you okay, June?" The concern fades from my voice before I finish the sentence as I feel very clearly exactly what's wrong: my hand on her hip finds only her very bare hip, not a pair of cotton panties. "Oh shit..." I am suddenly grateful I came up beside her instead of behind her.

"My, uh..." June looks over at Jeff, "My panties did not survive that dive..." She blushes, my hand still on her hip. "I can probably still swim without them, though, thanks..." I let her go and she paddles over to the side of the pool, scanning the water.

"Shit." I pull myself up onto the board, and look down. "Ah, there, look," I nod to Jeff and he nods back, slipping under.

"I'm sorry, I..." June looks abashedly up at me in the moment after Jeff dives, her delicate face wrought.

"What?" I just look confused back at her, the waves gently twisting their reflection of her partial nakedness up at me.

"Got'em!" Jeff pulls up beside her with a grin. "So nice of you to give me a gift, June!"

"Um, no, I think..." She pulls the panties delicately from him, "I think I'm gonna hop in the shower?" She smiles up at me, awkwardly trying to tug on the wet cotton under water, before turning to the stairs.

Jeff gives me a look and I frown a shrug back.

"Um, alright, maybe later?" He offers, and she nods, stepping up out of the water, rivulets once more cascading down those shapely cheeks, her panties now just slightly askew as she crosses one arm against her chest, the other on her crotch.

"Ya, definitely, um, this was super fun..." She glances back at us with a half-smile, scurrying over to her discarded clothes, holding them to shelter her nudity as she heads in, "I'll hang out with you guys again after I get this chlorine out of my hair!"

She disappears inside, almost certainly leaving a trail of puddles across the kitchen floor.

"What was that about?" Jeff frowns.

"I think she was just nervous." I slip into the water. "Just... go easy on her, okay?" I look serious at him. "She's not one of your college girls."

"Right..." Jeff considers.

The other kind of pool

"Hey..." June steps into the basement and I glance up from the pool table to see her in nothing but a towel. Her wet hair clings to her face and shoulders, her hand nervously clutching the tightly-cinched front of the white cotton draped snugly around her presumably naked body.

"June..." I see the shake in her eyes as she licks her lips. Jeff and I have already knocked back another beer or two waiting for her, but I can still tell she's clearly not as comfortable with this as she thinks she is.

"I just thought I'd join you boys for a game, while my hair dries?" She smiles an attempt at coyness. Jeff is more willing to be fooled than I.

"I'll rack'em, you can break!" I look his way to catch his eyes wide, eager for a piece of that ass. I glance down, the bottom of the towel is low, but, not low enough. Shots might get tricky, even for her.

"Oh, shit, he has no idea you..." I start but June puts her finger to her lips. June is a fucking rockstar at pool. As good as Jeff and I are in the water, she's twice that with a cue in her hands. On a good day, giving her the break means she could probably clear the table before we get a chance to take a shot.

"Promise to take it easy on me?" She grabs a cue and steps up beside Jeff, one hand still delicately clutching the front of her towel together. God that thing just hangs off her curves...

Jeff shoots me a glance. I hesitate, but feel for my nervous sister. They both clearly want something to happen here, I can play wing man to them both, I guess, and follow through on June's little deception. "Why don't we make it interesting?" I offer, half-heartedly. Hey, June will almost certainly get to see Jeff naked this way, it's the least I can do for my little sis.

I guess.

"With two on one?" June subtly aligns the teams as she feints a pout, "That hardly seems fair..."

"We'll alternate!" Jeff offers. "And both of us lose something for one of yours..."

He and I are in swim trunks. She's in a towel. What even is this game.

"Okay... and I break?" Now that she's starting to feel in her element, she definitely pulls off looking coy as fuck. And with his shit-eating grin, Jeff clearly has no idea what he's getting into.

"Go for it!" Jeff finishes racking the balls and steps off to grab his drink, handing her the cue ball. She pulls her hand from her towel, and it stays snugly in place as she delicately circles the table. She has that towel tight, I don't even detect the faintest of jiggles from her normally abnormally perky chest.

"Alrighty..." She places the ball and leans in for her shot. Between bending and turning carefully against the table to avoid letting the towel ride up in back and her arms moving apart to align the shot, the cinch at the top of her towel slips noticeably. Well, noticeably to me. She's too into the shot to realize it as she slams a hard break, the cue ball spinning to a perfect stop as the rest of the table explodes into action.

"Your towel..." I lean in and whisper. She glances down, then up, mouthing a thanks, hooking her fingers awkwardly into her cleavage. After her quick adjustment, the towel is... not as snug as before. And significantly lower. That is... a lot of my sister's bare cleavage right there.

Oh hell.

"Looks like two stripes, I'll take stripes..." She saunters around the table, clearly barely even considering what that last shot did to her attire, wholly heedless of my quiet warning, and grins as she spies the right next shot. She scurries around the table for it, slipping in front of Jeff and I. Jeff happily steps back to watch her lean into the table, and I step well out of range of her pool cue.

Already engrossed in our ensuing defeat, she neglects to consider our angle behind her. A slightly more delicate shot than the break, June takes a little less care in how she bends and twists, and the bottom of the towel slips quietly up her backside.

It was one thing to see my sister's mochi-soft cheeks in those mostly-transparent panties from across a pool. It's another to have them slipping out entirely bare from under a towel within arm's reach. Jeff seems to have the very same thought, and starts to reach out a hand just as she's making her shot. I smack him away with a glare. He pouts at me, sipping his beer, and June is none the wiser.

She perks upright after the shot. The somewhat neglected front of her towel is clearly once again impacted by her quick movements, and it suddenly slips free. Her back to the two of us, she deftly catches the white cloth as it billows out, clutching it back around her and re-tightening it against her chest.

She shoots a nervous look back, having just inadvertently flashed her bare breasts at the empty half of the room, and Jeff grins that grin. I see a little more apprehension in her look, though, than she probably meant to let on.

"Sorry about that..." She blushes, clutching the towel. She rests the cue against the table, tugging at her front, trying to make it a little more taut this time.

I try to wipe all thoughts from my mind and circle around the table for my beer. I knock it back, looking away as my sister sizes up her next shot. Presumably Jeff and I are most of the way to losing at this point. I turn around to see her bent over double, leaning across the table, Jeff's eyes in a broad grin at her presumably utterly bare backside.

Apparently taking a liberal interpretation of keeping his hands off my sister while she's shooting, he angles his beer bottle behind her as she pulls back, and from the way she jumps as she tries to shoot, I can only imagine what the cold, wet glass made contact with.

"Ah!" June shrieks, the cue ball going wild. She jumps up, looking wide-eyed back at Jeff, swallowing, half smiling. Nothing sinks.

As the tables slows to a rest, he breaks the tension with a laugh and she chuckles in response, a less bashful, less than embarrassed smile in her eyes that I've... never seen before? Like someone else is in there, sparkling out from behind those eyes. A girl I haven't met.

I huff and heft my beer. I could just leave and let them at it. I take a swig and glance for the stairs.

"Um, your shot..." She nods at Jeff. He absent-mindedly adjusts his obvious bulge in his shorts, June very clearly noticing with a quiet blushing bite of her lip, and circles the table. He takes a shot, the cue ball banks a few times, narrowly misses sinking one of ours, and slips into a corner pocket.

"Shit." He frowns. He kinda sucks at this, doesn't he?

June giggles, traipsing over to the pocket, reaching in for the ball, the smile I'm used to seeing back. That winning smile; the smile she makes when she's winning.

"Okie dokie!" She plops the ball down on the table opposite Jeff and quickly takes a shot. Standing behind her, I try not to look at where Jeff's bottle tread a moment ago.

The ball comes to rest near where it started, two more of hers sunk in one shot. She scans the table, then twists, cocking her hips, angling for the next shot. She shuffles her feet and I can't not see it now.

Fuck. What am I looking at. Why am I looking at this. Jeff should be here. I should not be here...

I tilt back my nearly-empty beer, my eyes glued to the smooth, bare flesh peering out from between my sister's spread thighs.

Stop looking at it. Stop getting so fucking hard.

Stop trying to tell if that glisten is from Jeff's bottle or...

I close my eyes, but even then, my little sister's smooth pussy lips are all I can see.

"Yes!" June blurts, and I open my eyes to see her jump up, giddy with that shot, her towel responding exactly as before.

And that's when I realize why Jeff

isn't

on this side of the table.

As the towel falls, Jeff grins, taking a swig of his own beer as his eyes soak in the sight of my sister's bare breasts. She spins as she realizes her repeat mistake, turning away from the boy leering at her and right at the boy trying desperately not to.

I keep saying her breasts defy gravity. Because they do. I've never seen anything like it, and until now, I've never seen them do it completely bare, out in the open, every ounce of those apple-sized handfuls within arm's reach... within lip's reach...

It's like they're resting on a shelf in the air. No, they still have that curve, that pear shape, that complex, convex concavity. Like they're in the world's most egregious push up bra, but it's invisible, and the way they move when she moves, it clearly provides no support at all. They punch out further than tits two weight classes up, and their jiggle makes jello blush. If her ass cheeks look like they have the supple smoothness of mochi in your fingers, her tits look like they'll feel that way on your tongue. Just the sight of them makes you want to take those pink nipples between your teeth and tease down on them ever-so-gently until she squeaks out in protest, until her whole body writhes the way her breasts jostle with her every move.
