Ken lets himself into the house, cursing himself for leaving his client’s file
behind when he left an hour earlier. He mutters a few fouls words for his
client as well, for making him go in on a Saturday. As he walks past his son
Nick’s room he peeks his head in, to see if the teen had woken up yet. What he
sees has Ken immediately grinding to a halt just outside the partially-opened
door. He opens his mouth but no words come out, too stunned to react.
Nick is sitting on the edge of his bed, with his younger sister Skylar on the
ground at his feet. It's a fairly common sight, the boy has always been
fastidious and careful, never one to sprawl on the ground like his younger
sister. Skylar on the other hand, is constantly plopping herself down wherever
she deems the most convenient. Oftentimes Ken will come home, only to trip over
her where she lays in the middle of the living room.
This time, however, Skylar is on her knees at the foot of Nick's bed, her
glossy pink lips wrapped around her brother’s cock. Her right hand is gripping
the base of his member while the left is settled on his hip. Nick has both
hands gripping his comforter, his mouth open and his chest heaving with his
panting breaths.
Ken is frozen in place, watching the scene before him with shock clearly
written across his face. He watches Skylar pull back, removing her mouth from
Nick’s member, her small hand moving to stroke him from base to tip.
“I liked it better last time,” she says, tilting her head and staring up at her
brother. “We can do that again if you want.” She speeds up the movement of her
hand and sits back on her heels.
Nick seems to still be catching his breath, unable to answer her for long
moments. Finally, he lets out a deep breathe and stands up. He bats Skylar’s
hand from his cock, stepping around his sister and stopping on her right.
Ken ducks his head out of the doorway, not wanting to be seen. He presses his
head against the wall and breathes deeply for a minute. He knows he should
leave. It’s not appropriate to spy on his children like this, and they’d
obviously waited until he left the house before starting. After a minute of
hearing nothing but silence coming from inside, Ken chances another glance into
the room. He gulps when he sees what his children are doing.
Skylar has turned to face Nick, still sitting on the ground at his feet. Now,
however, instead of letting his sister take control of her movements, Nick has
a hand wrapped around the back of her skull and is thrusting his cock into her
mouth. A look of peace has settled on Skylar’s face, her hands laying unmoving
on her thighs. Soft grunts accompanying each flex of his hips, Nick readjusts
his grip on his sister’s head and begins thrusting deeper into her throat.
Skylar moans as his cock hits the back of her throat.
“Fuck, Sky, your mouth,” Nick groans, his head falling back on his shoulders.
He grips harder at her skull and pulls her face closer, her nose buried in the
curls at his base. Ken can clearly hear her throat working over her brother’s
cock, the wet clicking noises loud as he breaches her throat over and over.
Her hands finally move from her thighs, one gripping at Nick’s thigh, and the
other dipping into the waistband of her skirt. As Ken watches, her hand
disappears and settles into a rhythmic circling, that can only mean she is
working her clit. Ken moves a hand to the front of his pants, pressing against
his aching cock. As he watches his son fuck his daughter’s throat, he slowly
unzips his pants, pulling out his cock and squeezing the base to relieve the
pressure. Ken strokes himself, settling into a rhythm matching Nick’s thrusts
into Skylar’s mouth.
All three lose themselves in their pleasure, the room filled with the obscene
noises coming from Skylar's throat and with Nick’s panting breaths. Nick lets
loose a guttural groan. As he tips over the edge he brings both hands to
Skylar’s head and pulls her in tight, burying his cock as deep as possible. He
shudders with his release, finally loosening his grip as he shoots his cum
right down her throat.
Skylar keeps his cock in her mouth, his softening member resting on her tongue.
She cleans him off, her tongue gentle and thorough. When she's satisfied that
she's swallowed every last drop she finally lets him slip free. She rests her
head against his stomach, catching her breath. After a long moment she pulls
back and looks up at her brother, a smile in her eyes and a smirk on her lips.
“Oh yeah, I definitely like that much better. Looks like you did too,” she
says, her voice rough.
Nick shakes his head and laughs. “You're something else sis.” He rubs a hand
through her hair. “I didn't hurt you, did I? I got a little rough at the end,”
he says, an apologetic look on his face.
Skylar stands up and stretches her back. “Nope. In fact, it gave me a few more
ideas of things I wanna try.” She leans against Nick’s chest and grins. “I'll
add them to my list.”
Nick shakes his head again and wraps his arms around her waist in a hug.
“You're going to kill me Sky.”
She sighs and nuzzles into his neck and sing-songs, “Oh but what a way to go!”
She pulls back and raises up into her tiptoes to place a chaste kiss on his
lips. “Now, I do believe you owe me an orgasm, mister.”
Nick tightens his arms around her and picks her off the ground. “Is that so?
You think you've earned it?”
Ken, still standing just outside the bedroom, brings his hand to a stop on his
cock and prepares to go to his own room to finish himself off. He watches as
Nick slides his hands to Skylar's ass and hikes her up, then turns to lay her
on his bed. He follows her down and arranges them until she's on her back and
he's laying on his stomach between her legs.
“I'm pretty sure,” she replies. Her hand sneaks down his body and grips his
flaccid cock, “and I'm pretty sure this guy would agree with me.” She starts
stroking him lightly, and tilts her head up to kiss Nick again. “Think you can
get it up again soon? I want you to fuck me.”
Ken blinks and tightens his hand on his cock, frozen again where he stands.
Nick groans into her mouth and plunges his tongue inside, thrusting his hips
into her soft palm. “Just give me a few minutes,” he mumbles. “But until then,”
he trails off, detaching from her mouth and pulling back from her grip. He
slides down her body and guides her legs up over his shoulder. “For now just
let me make you feel good.”
Skylar arches her back off the bed at the first touch of his tongue to her
pussy. Nick pushes her skirt up over her hips before burying his face between
her legs and devouring her wet cunt. Ken lets out a small groan and resumes his
stroking, shocked as he watches his son go down on his little girl. ‘She's not
wearing any panties!’ he thinks to himself, shocked. ‘How often does she walk
around the house in her flirty short skirts, bare underneath?’ He squeezes his
cock again at the thought.
He watches Nick eat her pussy, mouth flooding at the thought of tasting his
daughter's sweet juices. He fucks into his fist faster, losing himself in his
thoughts. Ken imagines himself in Nick's place, his mouth latched onto his
little girl's pussy, drowning in her juices as he licks her to orgasm over and
over.
On the bed in front of him, Nick has quickly worked two fingers into Skylar's
slick cunt beside his tongue, stretching her for his cock. He removes his
tongue, replacing it with a third finger and moves to suck on her clit. Skylar
lets loose a high-pitched keening sound, the dual assault tipping her into her
first orgasm. Nick doesn't let up, just sucks harder on her throbbing clit and
thrusting his fingers deep inside of her, immediately sending her into a second
orgasm right on the heels of the first.
Ken watches her writhe in pleasure on the bed, and as Nick licks her to her
third orgasm he follows, his hand squeezing tight around his cock and cum
coating the wall in front of him. He's unable to hold back a groan, and he
worries that he'll be caught. He opens his eyes, thankful to find his kids
haven't heard him, too wrapped up in each other to notice anything else.
At some point when Ken had been lost in the haze of his own release, Nick had
thrust his now hard cock into Skylar's pussy. He was now pumping his hips hard
and fast, fucking her with all his strength. Skylar drags her nails down her
brother's back, then digs them into his ass cheeks and pulls his hips in hard.
Nick stays buried inside her as deep as possible, grinding his hips into hers.
He wedges a hand between their bodies and finds her clit, massaging the small
bud in time with his hips. He brings his mouth to her nipple, tracing his
tongue around the tight peak before sucking it into his mouth.
“Oh shit, oh god Nick!” Skylar moans, arching up into his body. She brings her
hands to his hair and pulls him from her nipple, crashing their mouths
together. She sucks on his tongue and bucks her hips up into his. She rips her
mouth away and lets out a deep moan. “Right there Nicky, fuck! Don't stop
please, I'm so close!”
Nick drives his cock into her tight cunt, sweat pouring down his face. “Come on
Sky, come for me. Come on my cock!” He puts his thumb right on her clit and
rubs, sending her screaming into another orgasm. She tightens around him and he
can't hold out any longer. He manages a couple more thrusts before his hips
come to a halt and he and releases deep inside her.
Ken watches his children cum almost simultaneously and feels his spent cock
twitch in interest. He stays in his spot and watches them come down and catch
their breath. Nick pulls out of Skylar's pulsing heat and slips onto his side
next to her. He wraps an arm around her shoulder and draws her into a kiss.
They murmur back and forth, too quiet for Ken to hear. He begins to worry about
being found out, so he turns away and slowly walks down the hall to his own
room.
He cleans himself up in his bathroom and changes shirts, having sweated through
his first one. Once he's presentable again he unearths the dreaded folder from
his desk and exits the house, making sure to not make any noise. He gets into
his car and pulls away, thinking about what had just happened. ‘How long has
this been going on?’ he wonders. ‘How many times have they fucked with me in
the next room, completely unaware?’
As Ken drives back to work he comes up with a plan, because now that he knows,
he wants to know everything. ‘First thing tomorrow I'm going to the hardware
store,' he decides, ‘a few well-placed cameras around the house should do it.’
He smiles to himself, mapping out in his mind the best spots to hide the
security cameras. That'll teach his kids from hiding from him.
