-x-X-x-

It's a nice, idyllic summer morning at the Potter Manor. There's a self-cooking grill off to the side, a table magically filling with gorgeously cooked hot food, and to cap it all off, a pair of gorgeous babes lounging by the pool. Hermione Granger wouldn't necessarily count herself as one of those babes, but there's no denying she is one, the curly-haired brunette looking absolutely fantastic in her bikini, even as she reads a book.

Meanwhile, her boyfriend's obscenely hot mother, Lady Lily Potter, is also lounging by the pool in nothing but a rather skimpy string bikini. Lounging on her front, she's enjoying the sun's glow spreading across her creamy skin, a Charm applied beforehand making it so that she doesn't have to worry about sunburn. Thanks to magic, she gets all the benefits of a clean, all-natural tan with none of the drawbacks.

Behind her sunglasses, Hermione just can't resist little peeks over in Lily's direction, even as she pretends to read her book. Harry's mom is just… umf, for lack of a better word. She's the epitome of the Classic MILF, with a body that holds up despite her being a mother, despite her years of age. She's absolutely gorgeous, and Hermione can't help but be a little jealous… while also admiring Lily in her own bisexual way.

Of course, Lily is well aware of Hermione's glances. Her son's girlfriend is a cute little thing, though not so little anymore. She still remembered when Harry had first introduced them to his first friend at Hogwarts. Hermione Granger was adorable back then, but these days she was all grown up and it showed.

Knowing that the younger witch was constantly sneaking glances in her direction, Lily made sure to give her quite the show as she teased her with little glimpses here and there. Nothing too perverse or overt, certainly nothing to make it clear that she knew Hermione was looking… but certainly enough that she expected the brunette bookworm's nipples to be showing through her bikini top when Lily next looked over.

It was quiet and altogether very idyllic, with the only noises being the birds chirping in the background and the light breeze coasting through the area, and the sizzle from the self-cooking grill doing it's work.

And then, startling both women quite badly, Harry and James Potter, Heir and Lord of House Potter respectively, come racing out of the back of the house wearing nothing but swim trunks and playfully wrestling and shoving at each other. The father-son duo are laughing and having a blast, and both Hermione and Lily are watching them with affectionate, adoring expressions on their faces… right up until the two wizards reach the water.

SPLASH!

With a great titanic upheaval, the two tip overboard, crashing into the pool at the same instance. Their combined body weight causes quite the cannonball-splash, a great deal of water being displaced in the process, and thanks to just how it is they fall, both Lily AND Hermione turn out to be in the direct splash zone.

As Harry and James surface a moment later, it's with James holding Harry in a headlock, playfully noogieing his only son as Harry sputters but also laughs uproariously, eventually ceasing his struggles and relaxing in his father's grasp.

"Next time, old man!"

James, also laughing, gives Harry a cheeky grin even as they both climb out of the pool.

"Age before beauty, kiddo! Every single time!"

It's at this moment that both women finally catch up with the fact that they've just been soaked by the antics of the most important men in their lives.

"Harry!"

"Boys!"

Hermione is none too happy that her book got wet, though of course the cleaning enchantment it comes with is already putting the magical tome to rights. Lily, meanwhile, is just as incensed, sounding quite exasperated with her two men, as if she's dealt with their crazy antics for far too long… which really, she has.

As the two witches sit up in their lounge chairs, directing heated glares over at the wizards coming out of the pools, said outrage is suddenly muted by just what it is they're both witnessing. Blushes spread across each of their faces at the sight of their manly men soaked and looking all the more amazing for it. Water glistens down their pecs and abs as their muscles flex from the exertion of getting back up to their feet.

For a moment, James and Harry look like they've been caught with their hands in the cookie jar at Lily and Hermione's initial exclamations. But then they see the secondary reaction each witch is experiencing, and once they realize that, the two grin and exchange a knowing look followed by a fist bump. Separating, James heads over to Hermione, and Harry heads over towards his mother.

Somewhat dumbstruck, Hermione just can't stop staring, head craning up to keep on looking as James towers over her. Her pretty pouty lips form a big O of surprise as her fingers shakily reach up to splay over one of his massive pecs. Lily, meanwhile, is left in a similar state, her eyes widening as her own baby boy looms over her, starting to lean down so that she can appreciate just how well-built and physically powerful he's become.

Chuckling, James reaches down and casually lifts Hermione up off of her lounge chair and onto her feet with one hand. He brings her against her chest with this, and she blushes profusely for a moment before he lets her go and backs away. But not before giving her plush rump a gentle smack.

"Go and grab me a drink from the fridge, sweetie."

Oh Merlin, Harry had told him, hadn't he? Hermione goes scarlet as she mumbles out an eager 'Yes daddy~' and heads inside the manor to do as she's told. As it turned out, Hermione Granger had a Daddy Kink a mile long. She addressed Harry as 'Sir' in private, and absolutely loved being disciplined and taken to task by her boyfriend. To have his total DILF of a father give her a spanking and order her around… honestly, it was like something straight out of one of her most lurid fantasies.

Meanwhile, back outside at the pool, Harry isn't proving idle with his own mother either.

"I'm a little thirsty, mom. You don't mind, do you?"

Even as he asks, he's already yanked down her practically nonexistent bikini top, letting her already mostly exposed breasts bounce out a little more. Most importantly though, her nipples are exposed and even already starting to lactate in anticipation of what was to come.

"O-Of course not, b-baby…"

Grinning wickedly, Harry leans down and grabs hold of his mother's amazing rack, bringing his mouth to one nipple and then the other as he begins to suck and slurp up her breast milk. Lily's condition was somewhat rare, as it were. Very few women kept lactating for so long after they gave birth. And to have it tied into her arousal as well… well, luckily she had magic to keep herself from being embarrassed out in public.

Right now, though, the Lady Potter is more than happy to let her beloved son take care of her problem and get his fill at the exact same time. She's never been able to say no to her baby, that's for sure. And now that he's all grown up and just as much of a man's man as his father, Lily finds it even harder to resist his wants, his desires, his every need.

Meanwhile having sent Hermione off with her task, James isn't really inclined to just sit around and wait for her to get back. Chuckling, he saunters over to his son and wife and shakes his head as he watches Harry go to town on Lily's tits for a second.

"Such a ravenous little fiend we beget, Lils. You never did teach him how to properly share, it would seem~"

With that teasing done, James nevertheless forces his son to share anyways. Lily IS his wife after all, so, sliding into place, he pulls down his trunks and lets his hard cock spring free as he moves into position behind his gorgeous wife. The red-headed muggleborn can only moan as her handsome, masculine lord husband's hands grab and grope at her amazingly thicc, absolutely pristine posterior for a moment, before ultimately he begins to lift her ass up.

She ends up straddling the lounge chair, her legs spread on either side of it, her back arching beautifully as she pushes her tits into Harry's face while also pushing her ass back into James' hands. His cock comes into play a moment later as he lifts her just a couple inches off of the lounge chair and proceeds to thrust forward past her bikini bottoms into her sopping wet snatch.

Lily's wanton moans fill the air, easily overcoming the chirping birds and the sizzle still coming from the self-cooking grill as she's sandwiched between the most important men in her life. Of course, now that James is fucking her, Harry simply can't hold back any longer. Having drank his fill from her ever-lactating teats, her beloved son finally pulls back and yanks down his own trunks, releasing his own fat erection from its confines, to the point that it comes right up and hits her across the face with a meaty smack.

"Look what you've done to me, mom. You need to take responsibility for your actions…"

"Yessss-mmph!"

He's already gathering up her scarlet red locks into a ponytail as he's talking, so when she answers him, she's cut off in the middle by his cock slipping past her full, pillowy lips and into her mouth. Lily's eyes nearly roll up in her head right then and there. Getting spit-roasted between her boys is exactly the sort of thing that the gorgeous Lady Potter loves.

Laughing as he feels his wife's cunt tightening around his cock in a sudden explosive orgasm, the only change being that Harry went from sucking on her titties to pistoning in and out of her throat, James rears back a hand and gives Lily's ass cheeks a couple of harsh swats and gropes, spanking her and then squeezing her ass nice and hard, feeling both the firmness and the jiggle to it as he does so.

"Fuck, Lils… you're still the same horny little slut I pounded back in our school days, even after all this time…"

In between Harry pounding her throat, while she's getting some air, Lily moans out throatily and gives an honest answer that just makes the Potter men go even harder as a result.

"O-Only for my boys~"

Harry and James make eye contact over her, and a moment later they're fucking her all the harder, all the faster. Lily chokes on Harry's cock as a result, her still lactating tits bouncing and jiggling all over the place in the process, but if she minds the forcefulness, she certainly doesn't express it.

"Gagkh! Gagkh! Gagkh!"

Quite the contrary, even as she's gagging on her son's big fat dick, she's wrapping her arms around his waist, her hands grabbing hold of his muscular, completely firm buttocks as she desperately tries to draw him in even further.

It's this spit-roasting that Hermione walks back out to. The brunette witch nearly drops the bottle of chilled butterbeer that she's gotten for James at the sight of father and son giving it so fucking harry to Harry's mother. But she's not disgusted or anything like that… she's utterly turned on by the sight. Blushing down to her chest, with her legs quaking with need, Hermione quickly approaches the threesome happening in the Potter's spacious backyard.

"H-Here you go, d-daddy…"

James looks over from fucking his wife's delicious cunt from behind and smiles at seeing Hermione holding out his drink to him. Taking it from her hands, he pops the cap off with a quick easy flick and tips it back, drinking down half of the butterbeer in one go without missing a single thrust into Lily's sopping wet twat.

Hermione watches the display with wide eyes, her fingers twitching, her hands trembling with a need to touch herself, or maybe even better, be a part of what's happening right in front of her. Luckily, she doesn't get left hanging for long. Setting the half-finished butterbeer aside, James goes ahead and pulls right out of Lily's pussy, swinging his leg over the lounge chair and standing up in one easy motion.

As he towers over her again, Hermione just gulps, looking down between their bodies where his massive cock effectively takes up the vast majority of the scant space between them, ultimately curving upwards and pressing into her belly button due to it's sheer size. A moment later, she's on her back on the lounge chair she left behind earlier, and James is moving into position over her, his hands coming up to tear her bikini away.

She yelps and squeaks and squirms but doesn't protest or even resist as her boyfriend's dad takes his big fat dick, just as big as Harry's in fact, and begins to slide it against her dripping, drooling pussy lips. But he doesn't push into her, not at first. Instead, he teases her entrance with the very thought of his cock penetrating her, while at the same time reaching up and playing with her big, tanned tits. Both James and Harry have great, honking bear paws for hands, big manly things that would completely and entirely encompass your average pair of tits.

Luckily, neither Hermione nor Lily could be considered 'average'. Not in the tits department, and not in any other area either. As James grabs and kneads and practically mauls the young brunette witch's breasts, he can barely fit even his large, masculine fingers fully around her titties. Much like Lily, Hermione's rack is the perfect size for molestation by the powerfully built Potter men.

Still, Hermione still isn't getting fucked, even now. Lord Potter is toying with her breasts and her as well, his cock sliding back and forth along her slit but refusing to finish the deed. And so, finally, with a whimpering whine, Hermione gives in and begs.

"P-Please, daddy! Please, w-won't you fuck me?"

That cutesy tone, combined with her bombastic body, always did the trick with Harry to get him ball's deep inside of her. For a moment, she thinks it'll work the same with James, as he stiffens up, staring down at her with slightly dilated pupils, his cock twitching against her pussy lips. But then he just grins and chuckles, shaking his head as he digs his fingers into her tits all the harder, drawing a wanton moan from her lips.

"No wonder you're Harry's favorite…"

And THEN he finally thrusts into her, right when Hermione is opening her mouth to beg some more. Instead of words, a low keening noise escapes her throat and out her open pouty lips, even as her eyes go wide and her face contorts in ecstatic pleasure. Harry's father is just as well endowed as her boyfriend, or perhaps it would be more accurate to say Hermione now knows where her boyfriend gets it from.

Either way, his cock is inside of her twat now, and she's moaning and squealing and trembling beneath him as she orgasms explosively along his cock. James, meanwhile, tosses his head back and lets out a heartfelt groan.

"Shiiit, your pussy is just as perfect as Lils', I swear to fucking Merlin…"

Speaking of 'Lils', neither James' wife nor his son are particularly idle, even in his absence. As he's toying and teasing with Hermione on her lounge chair after having fucked Lily for a few minutes only to proceed to leave her in the lurch, the red headed muggleborn's neediness is becoming all the more apparent. Harry has his mother's scarlet locks gathered up into a makeshift ponytail, but it's Lily who's doing most of the work. The 'venerable' Lady Potter is bobbing up and down on her son's knob with an intensity that surprises even him, while at the same time she's brought her hands up to her chest and is moaning as she massages and squeezes at her breast.

Down below, in the absence of her husband's great big fat cock, Lily is grinding against the lounge chair. A poor substitute to be sure, but there's quite the wet spot forming there all the same, very nearly a puddle at this point as the reverberations from her moan coast up Harry's length. Even as his dad is slaking his lusts on Harry's girlfriend, Harry himself is enjoying his own mother… and frankly, he's starting to finally get close, especially in the face of Lily's enthusiasm, her tongue writhing along his glans and the underside of his cock in equal measure, and her lips suctioned down around his shaft as she stares up at him with verdant emerald green eyes that match his own.

With a hoarse shout, Harry begins to cum, completely forgetting to warn his poor mother. Lily, taken off guard by the suddenness of her son's ejaculation, as well as swiftly overwhelmed by the size of his load, does her best to swallow it all down anyways. She has a lot of practice doing so with James, since her son takes after her husband in this avenue as well. But even with all of her experience, no warning is no warning… and the MILF is soon looking like some sort of erotic chipmunk, her cheeks ballooned outwards as Harry's seed explodes out of her nostrils and the sides of a mouth, making a rather epic mess of her face.

Harry WOULD feel bad, really he would… but the moment he's done cumming, Lily is pulling back and standing up. He doesn't even get a chance to let go of her makeshift ponytail before she's repositioned herself in such a way that her ass is grinding against his crotch and her hands are palm down on the lounge chair.

Bent over and ready to be fucked like the bitch she is by her son's glorious, prodigious cock, Lily wiggles and moans and mewls, right up until Harry finally gets the hint and thrusts into her from behind. Then, her moans and mewls rapidly turn into squeals and cries of ecstasy as the gorgeous red headed MILF's eyes proceed to roll back in her head and her tongue lolls out of her mouth.

The Lady Potter's incredibly lewd reaction to getting dicked down by her own son causes both James and Hermione to look over at the pair, and upon seeing the mess that Harry has made of his wife's face, as well as the way they're fucking, the hunky Lord Potter's eyes light up in excitement. Hermione can only squeak as she's yanked up off of the lounge chair by the big burly DILF currently fucking her silly, his cock slipping out of her for a second, but only momentarily.

Then, she's bent over in front of her future mother-in-law, staring Lily in the rolled up eye as James proceeds to spread apart her legs for her and penetrate her from behind, while also grabbing her by her wrists and jerking her hands back behind her. As he holds onto her arms and really starts to give it to her, Hermione is left inches away from Lily's face, jerking forward with every jarring thrust, and moaning up a storm as she stares at the older witch with wanton desire. Her nostrils flare with the scent of her boyfriend's cum all over his own mother's features, and Hermione knows what she wants right then and there.

Lily comes back to herself just in time to realize her future daughter-in-law is licking her son's cum off her face. Blinking stupidly, taking a moment to process what's going on, Lily can only moan right alongside Hermione. But once she gets what's happening, once she sees how Harry and James are fucking her and Hermione face to face from behind, she lets her tongue come up as well and begins to get into it, licking Hermione right back, and even heatedly making out with her.

Eventually, Lily pulls her hands up off of the lounge chair altogether, and in the split second before her upper half can begin to fall forward, she reaches out and latches onto her son's girlfriend for support. Seeing this, James and Harry exchange a look over the two bodies between them and proceed to step out from around the lounge chair, forcing Hermione and Lily in their trapped, dicked states to shuffle with them.

As soon as the lounge chair is no longer in the way, James lets go of Hermione's wrists, allowing the brunette witch to bring her own arms up to embrace Lily in the same way the red headed MILF is embracing her. The two gorgeous witches moan and writhes against each other, Lily's face and tits ending up cleaned of Harry's cum in no time.

And yet, in spite of that, both women end up all the messier for their makeout session, especially with Lily still lactating all over the place and their nipples and tits rubbing together as they're fucked from either end by the most important men in their lives. James and Harry, meanwhile, go to absolute town on the two tasty, drop-dead gorgeous witches currently sandwiched between them, grunting and groaning as Hermione and Lily cum again and again upon their cocks, their pussies tightening and their inner passages getting easier and easier to fuck as time goes on.

This isn't the first time James and Harry have done something like this, and it certainly won't be the last. This IS the first time the two of them have fucked Lily and Hermione together, but as evidenced by how EASY it was for something to start, no one involved is the least bit unhappy with how things proceeded. As Lily gets to know her future daughter in law better and Hermione does the same with her future mother in law, James and Harry are fucking into them both with deep, penetrating thrusts, not letting up for even a moment.

There's no denying that the two muggleborns are the most brilliant witches of their respective generations. Potter men have great tastes, that's for sure. And even for all the intense face fucking and doggystyle poundings and mating presses, Harry still loves his mom as his mom. She'll always be his mother, and she'll always have all of the respect and adoration he can give her.

Likewise, James may not have that long-lasting familial connection with Hermione, but he's known her since his son started school, effectively. He's heard all about her accomplishment, all about her achievements. That she's the second coming of his own beautiful, vivacious, genius wife isn't even in doubt anymore at this point, at least for James.

But as smart and brilliant and intelligent as Hermione and Lily are, right now they're just two horny sluts in need of a good dicking down by the big, masculine men in their lives. And that's something James and Harry are more than happy to give them. As the two wizards fuck into their respective witches, they grin at each other over Hermione and Lily's heads, even as the women make out and moan and cling onto each other for support between them.

Reaching up, James and Harry give each other another fist bump, their weird but incredibly close father-son relationship working as well as ever for the two of them, and then without further ado, they go even harder. Hermione and Lily's shrieks and screams of pleasure reach a damn fever pitch as both Potter men, recognizing that they're getting close yet again, start to slam into their respective witches with all due force, fucking the two gorgeous muggleborn brainiacs harder and harder.

For their part, Hermione and Lily squeal and squirm and writhe against one another, watching each other's faces contort in euphoric bliss as they cum again and again around those pistoning pricks, until finally it happens. Maintaining their hold on Hermione and Lily's hips, both James and Harry pull out at the same time, proceeding to paint the two witches from backside to the back of their heads with copious, thick, viscous amounts of white hot cum.

The two muggleborn witches simply tremble and shake as they find themselves coated in their men's seed, not a single ounce of their flesh or hair at all spared from the proceeding torrent of cum. And when James and Harry then let go of their hips, having finished upon their bodies, the two witches collapse to their knees, unable to hold their weight up even between each other anymore. Their wobbly legs give out on them, and they fall to their knees, collapsing against each other.

"Welcome to the family, sweetie~"

"T-Thanks, m-mom."

That's the extent of their exchange, before Lily and Hermione fall upon one another, absolutely ravenous. With so much seed to clean up, they spend quite a lot of time scooping it off of each other's backs, cleaning up each other's otherwise pristine, gorgeous, blemish-free bodies as they also heatedly make out with one another between eating the cum that they're collecting.

James and Harry watch this happen with lidded eyes and self-satisfied grins, stroking their cocks in the direction of the two beauties. At first, this is to release the last few spurts of ropey cum across them… but after that's done, it's to get themselves back to fully erect. After all, they're far from done. As the two witches clean each other up, and the two wizards get nice and hard again, the latter exchange another glance, followed by a nod of understanding.

They rotate around Hermione and Lily, and when the two women are ready for the next round, it's Harry who ends up with Hermione and James who ends up with Lily. Needless to say, none of them are exactly satiated yet. And besides, they have plenty of time left to kill.

-x-X-x-

By the time they're finished, Lily and Hermione are exhausted. Hermione more than Lily, for sure, with the brunette bookworm just sitting on her boyfriend's lap, part of his huge cock sandwiched between her thicc butt cheeks as they kiss and cuddle and just laze about. Lily, meanwhile, is a bit more experienced in handling burly Potter studs.

As such, she's still rocking back and forth on her husband's lap, albeit rather tiredly. The spirit is more than willing, given just how much of a nasty little slut Lady Potter really is at the end of the day, but the flesh is growing weaker and weaker. Still, she's riding him and they're making out, her womb just as packed with her husband's cum as Hermione's is with Harry's at this point.

Meanwhile, the table nearby is utterly filled with food at this point, all of it still perfectly fresh and hot. It's all ready to be eaten at a moment's notice, but it's also ready to sit there for another several hours if need be, the magical enchantment on the table keeping it all nice and edible. Not just edible, but downright delicious at that.

The self-cooking grill has long since run out of things to grill however and has quietly powered itself down for the time being, leaving the backyard rather quiet, as even the birds have gone about their business by now. The only sounds that can be heard at the moment are the quiet schlicking of Lily Potter's cunt sliding up and down her husband's cock, and the soft moans coming from Hermione's lips between smacks as she makes out with her boyfriend.

It's into this idyllic, albeit perverse scene that their guests begin to arrive. Escorted out into the back 'yard' by one of the Potter House Elves, numerous gorgeous witches, all wearing different sorts of sexy, erotic bikinis, begin to pile out one by one. Their guests have finally started to arrive, it would seem. Of course, the moment that they see the Potter Family (and Hermione, but she's practically family at this point anyways) and their current state, there's a whole lot of whining and complaining about things starting without them.

James and Harry just shrug and chuckle, exchanging glances, knowing full well that pretty much every single one of their guests is a horny, needy witch who fell in love with at least one of their cocks and just can't help but continue to come back for more. Lily and Hermione, meanwhile, exchange a similar sort of glance… but it's one that's more exasperated amusement than anything else.

They're well aware of the effects that their respective men have on the witches around them. After all, they're a pair of those witches too. Lily had to deal with it back when she went to Hogwarts with James, how he simply fucked anyone who propositioned him, and practically EVERYONE with a cunt and tits was willing to proposition him.

Hermione, it seemed, was dealing with the same, if their guests were any indication. But ultimately, that was perfectly okay. Lady Lily Potter, at least, LOVED to watch. And judging from Hermione's lip biting and smoldering gaze on more than a few of the younger witches that Harry had attracted to this party, she did as well.

The Potter men carefully dislodge themselves from their respective women and set Lily and Hermione back down on the lounge chairs to rest, leaving them where they found them, technically, but certainly not leaving them anywhere near the same state that they'd found them in.

As more than one witch drops to her knees upon James and Harry's approach, Lily and Hermione prop themselves on their sides and run their hands down their sexy, gorgeous, properly fucked bodies, moaning as they dip their fingers into their cunts, cheering James and Harry on as the two men begin to fuck the faces of every single witch who's arrived early.

The party had finally begun. Lily knew though by the end of it, her boys would be the only ones left standing. Every single witch, including her, would be left in a fucked silly puddle of flesh, unconscious wherever they were last plowed into submission.

Just as it should be.
