Summary
     Uncle Sherlock catches you in a compromising position.
Notes
     Depending on where you are in the world, the age of consent varies
     considerably.
     According to laws in England and Wales, the age of consent is 16, but
     if the person is a student of the older person it becomes 18.
     I have labeled this story with an underage warning as a precautionary
     measure. How old someone thinks this character could be will be left
     entirely in reader's imagination.
     Please read the tags for warnings.
     This has neither been brit-picked or beta'd.
Daddy and John have gone out for the evening, so you're home by yourself. You
try working on your coursework, but you eventually become frustrated with it
and take a break. You pad downstairs to the living room and try to watch some
telly in order to take your mind off of things. You sit down onto the sofa and
pick up the remote off of the coffee table. You press the on button and find
the television still set to the DVD setting. You're about to change it when the
DVD player clicks on and the disc starts up.
What you see before you onscreen is two gorgeous men sitting on a sofa kissing
one another. One of them starts cupping the rather large bulge of the other one
and then undoing his trousers. He sinks to his knees, pulls out the other one's
cock, and starts sucking it.
Part of you is telling you to turn it off, but the other part of you is
reaching under your skirt and sliding your fingers into your knickers. You
start to circle your swollen clit with your middle finger, gently at first and
then gradually add a bit of pressure. You start to moan softly, watching the
delicious acts of debauchery being performed on your television screen.
You become so engrossed in the movie (and what you're doing) that you don't
even hear the front door being opened. It isn't until a dark figure storms in
the room and pulls you out of your reverie.
"John! John! Are you here? I think I've... Oh."
You jump at the sight of your Uncle Sherlock standing just in front of the
sofa, looking down at you. His head then turns towards the noises on the
television. You try to scramble for the remote, but he's too fast and snatches
it off of the table first.
Sherlock leisurely removes his coat and drapes it over a nearby chair. He then
sits down next to you, his body presses up against yours. You try smoothing out
your skirt, but Sherlock places his free hand on your thigh, sliding the skirt
upwards.
"Does your father know you like to watch such naughty films? Of course, not. It
was probably already in the player. So when you turned on the television, it
just started up automatically. You most likely didn't know what to do at first.
You wanted to turn it off, but didn't because you were curious. Then you became
aroused by what you were watching, an unexpected surprise. Figuring no one was
home, you decided to take it upon yourself to indulge in self-gratification.
And that's when I walked in the door. Well, dear niece, how did I do?"
"Uncle Sherlock..."
He cuts you off with his mouth kissing yours. His lips are even softer than you
had imagined them being. Not that you'll ever admit that you imagined what it
would be like to kiss your uncle. His long fingers slip into your already
soaked knickers and starts teasing your clit rather pleasingly. You only now
just notice that the sound on the television has been silenced and open your
eyes when you feel the motion of Sherlock undoing his trousers with his other
hand. His lips gently pull away from yours. His eyes bore into you as he
focuses on your physical reaction to his deft fingers.
He then reaches into his pants and pulls out his long, hard erection. You lick
your lips at the sight of it and begin to bend down in order to take it into
your mouth, when Sherlock stops you.
"No. That's not what I want. I want to feel your tight, sweet, wet cunt wrapped
around my cock. I want you to ride me like a fucking race horse. Now."
You've never really heard your uncle use such obscenities before today. Of
course, hearing them in his deep, knicker-wetting baritone causes you to squirm
slightly in your seat.
"Stand up and face the television. I want you to peel off those knickers
slowly. Be sure to bend over so I may appreciate your gorgeous bum. Come on.
Don't keep me waiting."
You do as he instructs, even bending over exaggeratedly so your uncle can enjoy
the view of your luscious arse in all its glory.
"Excellent. Have a seat." he says as he pats his hands on his thighs.
He grips his cock as its base to hold it still. You spread your legs just
enough so you can sink down onto his cock, with your back flush against his
chest. When you are fully seated onto him; his hands grab onto your hips
tightly, his fingers leaving indents into your flesh.
"Well, what are you waiting for?" his voice growls low in your ear. "Move."
"Yes, Uncle Sherlock." you say simply.
You start bouncing up and down on his cock, eliciting deep moans from your
uncle.
"Oh, Uncle Sherlock! Oh my god! Oh..." you cry as his long prick seemingly hits
your g-spot every time he enters you.
Sherlock's voice in your ear sends you even closer to climax. "You love my
cock, don't you? You're such a good girl. Always the dutiful daughter. I wonder
what your Daddy would say right now if you saw you like this. Riding me like a
good little slut. Taking my cock. Letting me fill your tight hole with my cum.
Do you think he's watching us right now? My brother does love to watch, doesn't
he? Yes. Yes, he does. Well, let's give him a good show, hmm?"
Sherlock's hand snakes between your legs, rubbing your clit as you ride him
harder and faster.
"Uncle Sherlock, I'm going to cum.... Oh my gosh...." you moan as your orgasm
washes over you in waves.
Sherlock then grabs onto your hips firmly, thrusting into you hard until his
own orgasm rips through him and he comes deep inside of you. Without giving you
a moment to rest, he tells you to stand up and put your knickers back on.
"Don't you dare clean yourself until John and my brother have returned home.
Then you will show them what a good girl you are and let them fill your cunt as
well. You will do this for me, won't you?"
You nod your head in acquiescence.
"Good." Sherlock then looks at the clock on the wall and turns back towards
you. "Well, I have to dash. Tell John I was looking for him, all right?" In an
oddly uncharacteristic move, he kisses you on the forehead. He then grabs his
coat and leaves without ceremony.
You turn your head from the hallway back to the television. You hadn't even
noticed that the video had ended and the screen had gone black. You stare at
your defiled appearance in the reflection of it in disbelief. Your eyes gaze up
at the clock on the wall just above it. You chuckle softly and think, Daddy
will be home soon. You pick up the remote and press the button to switch off
the telly. You lean back on the sofa and smile contentedly. You can hardly
wait.

de Harry’s arse, he lost control of his breathing and started
panting heavily.
Fred grabbed both his and Harry’s cocks, smearing their combined pre-come
around and pumping them ferociously. “Harry,” he said breathlessly. “I want to
suck your cock. May I?”
“Guh,” answered Harry.
Fred took that as a yes and began kissing his way down Harry’s body. His hands
intertwined with his twin’s as he reached his prize, wasting no time as he ran
his tongue up the length of Harry’s cock and placed his lips around the head.
The exact moment Fred took Harry in his mouth, George replaced his tongue with
his finger and kissed his way around to Harry’s balls. The combined stimulation
was almost too much to bear, even more so when George began wriggling his
finger around and grazing his prostate.
“Fred, George,” he said desperately. “I’m – I’m so close.”
“Good,” was George’s muffled reply.
Fred quickened his pace as George added another finger and began sucking on the
sensitive sac. It was enough to send Harry over the edge, gripping onto the
sheets and groaning mercifully as he thrust his hips upwards and had the most
intense orgasm of his life.
After Fred sucked him dry, he and his brother raised themselves up to lean over
Harry as he tried to control his breathing.
“We’re not done yet,” said George.
“I hope not,” replied Harry breathlessly.
Both twins grinned at him. George still had his fingers in Harry’s arse, and he
accelerated his movements, causing Harry to squirm wildly.
“George wants to fuck you,” declared Fred.
Harry responded by rolling over and positioning himself between Fred and
George.
“Not yet!” exclaimed George, chuckling. “Fred has to fluff me up first.”
“Fluff?” repeated Harry.
“Observe.” Fred relieved George of his clothing in record time and straddled
him, grinding their cocks together, interweaving their tongues in a passionate
yet pornographic kiss. Slowly, Fred made his way down his George’s body,
finally burying his head between his twin’s legs. His eyes were locked with
Harry’s as he engulfed the entire length, pumped up and down a few times, and
raised off, leaving a very saliva-covered cock.
“You’re such a good fluffer, love,” said George.
Fred winked at his brother. “Thanks!”
They both looked at Harry. “Now you may assume the position,” they said
together
Wide-eyed and still amazed by what he just witnessed, Harry crawled between
them on all fours and bent over in front of George. Fred was right in front of
him, smiling contently, as George nudged his cock in Harry’s entrance.
Harry took in a sharp breath, and Fred immediately kissed him and started
stroking his hair. “Relax, Harry,” he said soothingly. “It feels much better if
you relax.”
Harry relaxed and felt George slide further in. George groaned as he buried
himself to the hilt and started to move. Harry was starting to enjoy it,
especially when George hit a certain spot inside him that made him see stars.
Fred leaned back so that his cock was directly in front of Harry’s face. “Do
you want to suck it?” he asked in a low voice.
Harry rolled his eyes in the back of his head and moaned as George hit that
spot again. Without bothering to answer Fred, he tentatively placed his lips on
the head of his cock and licked pre-come from the slit.
“Mmm,” said Fred appreciatively. “Take it in, Harry.”
Harry had no choice as George pounded into him particularly hard, pushing
Fred’s cock into his mouth. Harry didn’t mind; in all honesty, it was easier
this way. George’s cock ramming in and out of his arse caused Harry’s mouth to
bob up and down on Fred’s cock. Brilliant arrangement, if you asked Harry.
Both twins were screaming vivaciously in perfect harmony, filling out Harry at
both ends as if it were some kind of Weasley sandwich. George was hitting that
spot over and over enough that Harry thought he would come again just from
that, and Fred’s cock was so hard and throbbing in his mouth with the salty
tang of pre-come he decided he could get used to.
Just when Harry was about to be overcome with the many simultaneous sensations
he was feeling, George drove himself in one final time and came with a loud
grunt. The force caused Harry to almost deep-throat Fred, leading to a hot gush
of spunk that almost made him choke.
Slowly, George pulled his spent cock out of Harry, and collapsed on the bed
alongside his brother, both of them glowing with sweat.
“Bloody… brilliant…” Fred panted.
“Guh,” agreed George.
Harry was nowhere near as worn out as the twins. “So we’re done?” he asked
disappointedly.
“He asks if we’re done,” repeated Fred.
“As if we could go on,” added George.
“We’re not as young as we used to be, you know.”
“You’re quite an energetic shag.”
Harry grinned proudly.
Fred smirked. “If you’re still bored, I’m sure our youngest brother would love
to finish you off.”
“Maybe then we’d get to stop hearing about how nice your arse is,” snorted
George.
“W-what?” said Harry incredulously.
“Oh, like you didn’t know.” Fred leaned over the edge of the bed and hunted for
their clothes. “Ron has fancied you for years – why do you think he never asked
out Hermione?”
“Because they would kill each other before they even got a chance to shag?”
guessed Harry.
“Nope,” said Fred and George together.
“Do we have to spell it out for you?” asked George.
Fred tossed Harry his clothes. “Get dressed and go show ickle Ronniekins
everything we taught you.”
He didn’t have to tell Harry twice. He threw on his clothes and ran for the
fireplace.
“The Burrow!”
~*~*~*~
Ron didn’t even glance up when Harry arrived. He was lying on the couch,
leafing through a magazine.
“Harry, I’m sorry I yelled at -”
The end of his apology was muffled as Harry dove on top of him and claimed his
mouth. Ron was startled at first, but once he realized what was happening he
responded immediately and tossed the magazine aside, wrapping his arms around
Harry. Soft lips pressed against each other evocatively, tongues dueling
together in a never-ending battle.
An eternity later when they came up for air, gasping heavily, Ron looked up at
Harry’s lust-filled eyes. “Not that I’m complaining,” he said between gulps of
breath, “but what brought this on?”
Harry grinned wickedly. “I decided I wanted to look at the back of your head
after all.”
