WARNINGS: taboo brother-in-law, handjob, oral sex, rough oral, exhibitionism, daddy kink, while she was sleeping
Lily really ought to have suspected something when Vernon spends most of Christmas Eve plowing Petunia with red wine.
"Drink up," he tells her, more than once. They haven't even made it through dinner, and Lily's sister has easily imbibed half a bottle. Each and every time Petunia has managed to guzzle down the latest glass, Vernon is almost immediately there again, tipping her another generous pour. Mum and Dad are off in their own little world, enjoying the holiday spirit and discussing the evening plans they have to go carol singing with the neighbours, but it is patently obvious to Lily that her sister is quickly becoming sloshed. Petunia's own inability to say no to her fiancé is her downfall. She makes a few half-hearted comments about Vernon's generous attention, but continues to glug every last sip he provides for her.
She's nearly slurring her words and unsteady on her feet when Mum and Dad depart for their outing, and Vernon announces he'd like to watch It's a Wonderful Life.
"M-movie?" Petunia is blinking dumbly at him, her pale eyes watery and unfocused.
"It's tradition," Vernon declares, and is already shuttling Lily's sister toward the living room, with a very pointed look over his shoulder at Lily.
Lily's brain is in a tizzy, wondering what the man is up to. She has ideas, certainly…but surely he wouldn't…?
He sits Petunia at one end of the sofa, leaving her there with an almost unceremonious dump. She curls up on the cushion and leans heavily against the armrest, blonde hair drooping over her face. Vernon bustles around the room, turning out the lights and finding the correct station on the telly. He eventually takes his own seat on the middle cushion, then looks to Lily and gives the empty spot on his other side a welcoming pat.
"Come along," he orders, mustache twitching.
He has draped one of Mum's large crocheted blankets over his lap, and Lily doesn't bother to ruin whatever plan he clearly has going by scuttling as far to her corner of the couch as she can. Instead, as the movie begins to play, and Petunia continues to wilt further on her side, Lily gingerly sits down close enough to Vernon that their thighs are touching.
He is all heat and thrumming tension and Lily can practically feel his satisfaction radiating through the air.
Lily squirms, letting her knees fall open a bit.
Vernon sucks in a sharp breath, and for nearly fifteen minutes, the only sounds in the room are the quiet hum of It's a Wonderful Life, and the trio's sporadic breathing.
It's at the twenty minute mark that Petunia lets out her first little snore.
"Hzzz," she snorts, loud enough to break over Jimmy Stewart. Lily glances over. Petunia is fully draped over the armrest now, a rail-thin collapsed doll, officially surrendered to her drunken stupor. She's curled up in a way that will surely give her neck pains come morning, but she seems thoroughly passed out.
It is only a minute, maybe even less than that, before Vernon shifts in his seat, gently moving Mum's blanket off his lap to offer one end to Lily.
"Cold in here," he murmurs, and he drapes it over her lap.
When he says it, his eyes flicker over to Petunia, clearly checking if the sound of his voice stirs her any.
Lily's sister gives another muffled snore.
Lily begins counting then. One…two…three…
She has only made it to thirty-one when she feels dependably impatient Vernon shift beneath the blanket.
Four more seconds, and he has grabbed Lily's hand.
It hasn't even been a full two minutes since Petunia passed out, and somehow, stunningly, miraculously, Lily Evans finds her hand wrapped around her future brother-in-law's naked dick.
Holy shit! She thinks the exclamation loudly in her head, but feels her brain scrambling on what exactly to apply it to. There are so many possibilities. How the hell had he managed to get his dick out of his trousers without her noticing?! How unbelievably outrageous was this man, getting his fiancée drunk so he can get a handjob from her sister?! Mere days after meeting her! On Christmas Eve! And…
And!
Holy shit. He was big.
This, unsurprisingly, is where Lily lands. She loses the thread on the rest of the audacities almost the moment Vernon moves her hand to close her fingers around his already hardening shaft. God, he was thick! Lily has to bite back a little moan, her imagination already running wild. True, he was not as wide as Slughorn, but Lily had yet to meet any man who could match the Potions professor in pure cock girth, and she was ever on the lookout! Even so, Vernon's dick is definitely longer than the older man's, and as Vernon's own meaty fingers cover Lily's around the hot, thick rod, she notes that her fingers are barely touching fully around. She does delicious calculations, knowing Vernon wasn't fully hard yet, imagining herself fitting this big thick cock with its wide bulbous head at her pussy entrance, dreaming about the tight fit it will be as he enters her. God, it would be glorious. She has not had any dick in her in almost a week and she was feverish for it.
She cannot hold back her little squeak of eagerness. Vernon immediately shushes her.
"Quiet," he hisses, even as he begins to guide her hand up and down, closing it more firmly around his thick cock, his own breath hitching.
She tries to remember her role, gives a half-hearted, "Vernon…we can't…"
"Shh," he tells her, licking his lips. "You want it. Look at you. Harder."
Lily squeezes his cock almost without thinking, her eyes falling to her sister—who was right there. Christ, he was doing this when Petunia was right there.
Her pussy gushes.
Her raunchy reckless future brother knows exactly what he wants. He sets his desired pace, using Lily's hand like it's his own personally wanker, breathing heavily in the quiet room. When she catches on to his pace, he removes his hand, but almost immediately reaches across to start palming Lily's tits. It's somewhat clumsily done, her hand furiously jerking below the blanket, his wildly pawing her chest over it, even trying to scoop down the neckline of her dress so he can fondle her heavy globes skin to skin. They are trying not to make too much movement, too much noise, and it's all so deliciously wild and careless, Lily knows she'll be fingering herself to the memory of it later.
"That's it," Vernon whispers, despite him having shushed her only moments before. He seems utterly overwhelmed at the feel of her jacking his dick and her gorgeous tits finally being in his fingers. The words come out in an uncontrollable stream. "Little tease…needs a real man...uhhh—yeah, just like that…just for you…Daddy's big dick…can't wait to fuck these titties…ughh—faster!"
Admittedly, Lily's a bit caught out by the "Daddy" drop (though naturally a slut submissive like her doesn't mind a little daddy play—never mind that she'd been frigging herself to the literal idea of her boyfriend's father fucking her only a few days before!), and that breaks her rhythm momentarily. But Vernon must attribute this to a different source, because he unceremoniously yanks her hand off his dick and out from under the blanket. She barely has time to blink before he has already brought her hand up to his mouth, and he spits a generous wad into her open palm. With new lubricant provided, he jerks her hand back under the blanket to close back around his cock.
"Yes," he hisses.
The spit is warm and slick in Lily's fingers. As she begins to stroke again, it makes a sticky gushing sound in the quiet room. Lily imagines it's a similar sound to what her pussy will be making when Vernon eventually sticks this big, thick monster inside her.
The spit helps for a few minutes, giving Lily the chance to shape and squeeze and sculpt this hard and hot dick she's been offered, but it's not a long term solution. Twice more, Vernon urges her to "let Daddy give you some wet," and she obediently lifts her hand, but there's not enough. Vernon likes his wanking too firm and too fast to maintain without proper lube, and though Lily can see she's getting him closer and closer to release, he can never quite crest. She circles her thumb around his sensitive head, hoping that will help, but he only lets loose a noise of annoyed frustration that immediately finds Lily darting her eyes to Petunia. Somehow, thankfully, her sister is still snoring away, utterly ignorant.
Then Lily feels a hand at the back of her head.
"Suck it," Vernon barks, at the same moment he is grabbing Lily's hair in one meaty fist and shoving her face down. He barely seems to have enough sense to quickly lift the blanket from his lap before he shoves her head, and Lily only has a single moment to appreciate her first glimpse of Vernon's cock—hmmm, at least eight inches, veiny and ruddish, slightly crooked at the base—in all its glory before she finds her lips instinctively stretching around the big, hefty tool.
"Erg-hmm!" she gargles.
"Yes," he hisses.
He uses his brutal grip on her hair to begin mindlessly face-fucking her.
"Fuck!" he all but yelps, thankfully in a whisper, as he shoves her head up and down, up and down, fast and unrelenting, her mouth now an easy sleeve for his cock. Where before her handjob had been strained with friction, his dick is suddenly all wetness, the speed and strength with which he jerks her head creating a messy, drooling lather in her mouth that immediately drenches his entire penis. Lily's eyes begin to water, her jaw unclenching, her throat rubbed raw as Vernon rapidly finds the angle that shoves his hefty length as far as he can manage, and doesn't stop. It is brutal. It is callous. He cares only about getting himself off and doesn't give a damn about what that does to her…and Lily's pussy is on fire because of it. She loves being used. Loves being treated like an absolute slut, just a hole to be destroyed at any man's pleasure. She suspected Vernon would be the selfish and vicious type, and she feels herself getting close to her own orgasm with the confirmation. She can only hope he's like this in all elements of fucking. She can't wait to be buried beneath his big body as he shoves himself into her with careless hedonism.
Lily knows the violent face-fucking can only last for at most a minute or two. Vernon was already close, and methodically using her mouth like a pussy pushes him further and further to the edge. But she seems to go into an absolute trance, just a messy, mindless ragdoll slump, so turned on by the way she's being ravaged that surely her eyes are crossing and her tongue is flailing out like one of those silly cartoons. It feels like hours to her, so that when she feels Vernon's fingers in her hair begin to grip harder, his wild pumping of her head begin to lose its rhythm and instead revert to just clumsy thrashing, she is honestly surprised.
"Take it…take it!" he's huffing, and Lily's mouth—already gaping to its limit—merely continues to loll open over his cockhead as he can't seem to help lifting his hips up to more quickly meet her head during his final, fumbling strokes.
With an absolute roar, he gives once last mighty shove, and Lily feels her throat begin to fill with thick, yummy, wonderful, hot cum.
She's still mindlessly guzzling when something in the back of her mind blares: he roared.
Loudly.
Vernon had roared loudly as he came.
Petunia.
Almost as fast as she was thrust onto it, Lily is unceremoniously yanked off Vernon's dick, and shoved immediately back towards her side of the couch.
Petunia tiredly murmurs, "…Vernon?"
"It's nothing, darling," he says quickly, still entirely out of breath, the sort of brush-off that only an idiot wouldn't question. "Go back to sleep."
He is holding Mum's blanket to his lap like it's a lifeline. He reaches out to stroke Petunia's hair as she murmurs something else, but its slurry and nonsensical.
Lily licks around her lips. The taste of lipstick and flecks of drippy, yummy cream that had still been sputtering out as Lily was yanked from Vernon's cock fills her mouth.
Slowly, silently, she stands from the sofa.
"Good night," she whispers.
When she's finally upstairs in her bedroom, she locks the door, sets a Silencing Charm, and then promptly fucks her fingers until she passes out, covered in her own juices.
