The damsel downstairs and the monster upstairs

The first thing that William notices about the dark-haired, twenty-something woman is that her skirt is hiched up on one side. Most of her left thigh is bare, along with all of her right, and the occasional glimpse of her pussy. Her panties are long-gone, left ripped on the bedroom floor. A trickle of cum--No, more like a series of oozing globs--Runs down her leg, leaving a sticky trail on the stairs behind her.

As she stumbles onto the bottom step, one of the buttons on her blouse pops open. The remaining two are barely keeping it together, clearly aligned with the wrong holes. In addition to being askew, her top is stained: a dark patch surrounds the uneven expanse of cleavage, with more visible near the hem. It's also being pushed up from below: her belly is swollen, as though the skinny young woman has just eaten a huge meal.

Her formerly-professional hair and makeup are ruined, too, leaving her looking beyond-unkempt and a little unhinged... But from the look on her face, she's having the time of her life. Every shaky, deliberate step has some spring in it, too, and she flashes the gawking father and daughter a huge grin as she nears the kitchen.

"Th-thanks, um... I'm all done here," she giggles, running a hand through her tangled hair.

"I... Young lady, do you need anything?" The look on William's face is as concerned as it is confused. "A change of clothes? A ride somewhere? Is there someone I can--"

"Oh, no, my husband's waiting outside. I'll clean up back at the store--Oh, speaking of which..." She stumbles forward, another glob of jizz landing on the kitchen tiles with a splat as she leans over the table. Reaching into her breast pocket, she pulls out a slightly-soggy business card. "If Jason--I mean, If y'all need anything else--Anything at all--Tell him to call me--Um, us, okay?"

Not waiting for a reply, she turns on her heel and scurries out of the kitchen (and the Greene house). William can't help but watch her bouncing, half-exposed ass for a moment, before looking down in shame and embarassment...

...But after a moment, he glances up to see that his daughter doesn't share his sense of decency.

"Brook! Wh-what are you..."

The petite blonde is still leaning against the kitchen counter, but her hands are now between her legs. One rubs up and down the front of her pants, while the other toys with the waistband, threatening to slip beneath. "...Huh? Oh... Um, sorry, Dad..." Her hand keeps moving up and down her pussy.

"So stop! P-please."

"...Right... Okay..." With a disappointed sigh, Brook picks up her coffee cup and downs the rest... Including the gooey remnants at the bottom, which take a moment to ooze down onto her waiting tongue. "Mph. I'm gonna go, um, take a shower," she says, licking her lips.

"Sure, sweetheart, just... Stay away from Jason's room, okay?" He swallows hard. "He's, uh, p-probably tired... Time zones and all... Y-you shouldn't be disturbing him."

"Yeah, I bet he's tired," she says cheekily, winking at her father. "Later, Dad!"

"Bye," William replies half-heartedly, looking down again as he tries to forget the many literal and proverbial stains he just saw--Not just those on the freshly-fucked employee, but also the visible moisture between his daughter's legs.

A short while later, William decides to go upstairs as well. He has some work to do in his office... But more importantly, he feels an overhwelming need to make sure that Jason is in his room, and that everyone else is not.

Luckily, his houseguest's door is wide open, and it's plain to see that Jason is alone. It's also plain to see that the scrawny young man is sitting on the edge of the bed, naked from the waist down, his legs spread wide as he strokes--

"--Oh my God," William shouts, taking a full step back. The boy's cock is larger than any he's ever seen--Not just bigger than his own member, but quite possibly bigger than his own forearm. "J-Jason! You're--"

"...Ungh... Hey," Jason grunts, still tugging on his foot-long, impossibly-thick member. It appears to be only half-hard, drooping downwards as it pumps out a cloudy trickle of pre-cum that pools on the floor. But even when not fully-erect, it's large enough that every one of Jason's strokes involves his entire arm, as though he's pumping up a bike tire.

Not only that, but his balls are absurdly swollen as well: each is the size of a grapefruit--Bigger, even--And churning like a pair of clenching and un-clenching fists. With each shuddering pulse they grow: it's barely enough to be visible, but the gradual expansion is such that the appropriate fruit metaphor goes from "grapefruit" to "melon" in the short time that William spends gawking.

"How's it going, Will?"

It's William, actually, part of the middle-aged man's mind jumps to reply... But then he realizes that's not exactly the main concern here. Instead, he tries (and mostly fails) to blurt out about six sentences at once:

"You're--Is th-that--That's c-completely inap-p--Inappropriate--Is it real--Y-you can't--How--"

Each time he tries to catch his breath and speak more clearly, he gets a lungful of Jason's potent psychoactive musk. The bedroom is plastered with semen: only a small fraction of his emissions could fit inside the young lady who staggered down the stairs just minutes ago. There's plenty all over the floor, some dripping down the wall, and it appears the garbage can is full to the brim... Not to mention the soaking-wet bedsheets that are piled up in the corner of the room.

Shrugging his shoulders, Jason keeps right on fapping... But only for another few seconds.

Suddenly, his meat lurches from his grasp, growing more rigid in an instant. Then his balls contract, even more violently--William flinches as the boy's swollen orbs jump upward, going from hanging pendulously to pressing themselves against his shaft.

It's a good thing he does flinch, because a jet of thick white semen shoots out of Jason's member... Then another, and another... Plastering the floorboards, from the foot of the bed all the way to just in front of William's feet.

The poor man has to press himself against the wall in order to avoid getting thoroughly covered by his guest's massive, seemingly-unending blasts of jizz. Each cumshot is accompanied by an audible schplort from Jason's crotch, followed by a quieter splash as the almost jelly-like substance splashes down.

Of all the insanity that's happening before him, William finds himself focusing on the boy's testicles. Jason's fat nuts are still pumping upward and downward violently with each emission, working overtime to propel his pharmaceutically-enhanced jizz through a foot of cockmeat (with enough velocity left over to coat the hallway). They're shrinking, too--Though even as the last few globs ooze to the floor, they still look like a couple of slowly-throbbing baseballs.

After letting out a satisfied sigh, Jason leans back. "You're staring," he says matter-of-factly, shaking off his cock (and splattering even more of Alan's bedroom with jizz).

"S-sorry," William replies automatically, before taking a beat and shaking his head with disbelief. "W-wait, no... You shouldn't be..."

"We'll talk about it later," Jason says, standing up and moving towards the door. His cock swings with each step, still dripping.

"W-we certainly will, y-young man--"

The door slams.

Instantly, William feels a sense of relief--Enough to outweigh his irritation at being interrupted, and even some of the horror at seeing his guest brazenly desecrate a good chunk of his house. Respect takes a back seat to safety, and he's no longer face-to-face with something that his lizard-brain recognized as dangerous.

Shaking with adrenaline, he slowly turns and moves down the hall toward his office--Taking care not to plant his foot in one of the slimy globs. As he gets closer to the upstairs bathroom, he hears the shower running... And the loud, near-continuous moaning of his daughter.

At least she's in there, part of him thinks, while the rest begins the laborious process of forgetting and/or rationalizing what he's just seen. At least she's safe.
