one weekend, or how many different ways
Sometimes Dean puts
them to the test too, timing how fast he can make them cum, or

A/N: I'm not usually inspired by prompts, but
I've always toyed with the idea of adding Cas to the
Dante's verse, and when
this prompt came along it finally clicked ;D Thank
you, Anon!

And then Cas rolls into town. Cas, who Dean has some kind of
long-standing arrangement with, which involves entire weekends of
non-stop, unadulterated fucking - before Cas goes back to his job
or family or church or whatever it is he can only get away
from for a few days at a time. And while Dean may be a perfect
little cock-slut for Benny, he turns into a downright filthy
little cum-pig for Cas.
Benny notices it straight away, the first night they meet up with
Cas at Dantes. Benny still goes there with Dean every now
and then, to make use of the clubs many toys and specialty
rooms, or when he feels Dean might be missing his glory-whore
days and needs a really good gangbang. So its not like
theyve never invited a third party, or more, to join them
in certain controlled situations. And to be honest, when Dean
tells him about Cas, Benny is a little relieved the only
downside to Dean being such an insatiable cock-slut is that at
Bennys age, its exhausting so adding a
regular third into the mix would be good for both of them.
But not unless Benny likes what he sees.
And that first night at Dantes, Benny likes what he sees.
In fact, hes downright impressed.
He doesnt know exactly what hes expecting, but
when he finally sees the guy, that isnt it. Not that
lithe, leanly-muscled build or that head of dark, unruly
hair with 5 oclock stubble to match but when
Bennys eyes follow the line of that strong, chiseled jaw up
to unflinching blue eyes, he starts to get it. Theres
authority in the way the man holds himself, command in his voice
when he speaks just the kind of thing Dean loves to
bend over for.
The sling room is empty that night, and as soon as Dean lays eyes
on the vacant leather he says, I want in. So Benny
helps Dean up into the hanging chair, then settles himself on a
bench in the back corner of the room to watch.
Cas rims Dean until hes crying, cumming, and begging for
Cas cock anyway.
Its not that Cas is exceptionally good at it Benny
definitely has the edge when it comes to technique and tricks
but Cas has the longest tongue Benny has ever seen in his life.
And Benny has seen a lot of tongue.
But Cas is tireless at it too, fucking his tongue so
deep into Deans hole, for so long, eating Dean
out like hes been starving for it, which - after however
many months Cas has been away - he probably is. Yeah, Benny gets
it all right. In fact, hes never come so hard from just watching
before. And Cas hasnt even pulled his cock out yet.
Thats the very next thing he does, though, while Dean is
still twitching with the aftershocks of his orgasm, mewling to be
dicked. And yeah, thats pretty damn long as well.
Not as thick as Bennys, but still a nice looking piece. And
Bennys seen a lot of dick too.
He hasnt seen many people fuck like Cas does, however.
Again, what the man lacks in technique, he sure makes up for with
stamina. He just takes that pretty looking meat of his, and fucks
it into Dean like a hammer, driving and relentless, with a
precision that Benny knows is hitting the right angle every time.
And by the time the man starts looking like hes ready to
blow, Deans gotten hard enough to bust another nut too.
Clearly, Cas has learned Deans body well. But Benny
doesnt even get a chance to form any kind of jealousy over
it, because its one of the hottest things hes ever
seen, and Cas still isnt done.
Almost as soon as Cas is done loading up Deans hole,
hes licking it back out again, then feeding it back to Dean
with filthy, cum-filled kisses. And then, and then, Dean
begs to clean off Cas cock too.
Thats just about all Benny can sit back and take, then. In
three strides hes across the room, dick exploding inside
Deans ass on the first shove in.
And, Goddammit all to Hell, Cas licks that all up too.
Benny watches in a daze as Cas feeds it into Deans mouth as
well. But the two loads of cum Dean blew all over own stomach,
Cas swallows himself, smacking his lips with sloppy, satisfied
noises. And when hes done, he just smirks at them and says,
Cleanliness is next to Godliness.
They take Cas home with them that very night. And Dean spends the
next few days tied up, in various positions, while Benny and Cas
take their turns with him. By the end of the weekend, Deans
ass is so fuck-loose, they have no problems fitting both
their dicks inside him at the same time.
Dean still limps a little for the whole week afterwards. But
thats mostly from the strain on his hips, having had his
legs split open for so long. And more importantly, Dean also
smiles the whole week afterwards too.
So thats fucking that. Cas becomes their regular third.
Benny gets to sit back and enjoy the show when he needs a break,
and Dean just keeps getting as much cock as his slutty hole
wants, while guzzling on Cas cum, every chance he gets.
I dont get it. Benny brings it up once. Once.
Whats so great about the guys cum that you just
cant seem to get enough of it? he asks.
Seriously? Dean replies. Its like manna
from Heaven, Benny. You have to try it, he says,
before promptly going to his knees, sucking a load right out of
Cas cock, and feeding it to Benny, right off his tongue.
And yeah, that cum tastes good. Clean, and pure, and sweet.
(Well, as sweet as cum can be, that is.)
Not that Benny would ever admit it to the guy.
See, he and Cas dont exactly get along. Benny thought it
might be a jealousy thing at first hes grown kind of
fond of Dean, after all but the only time they ever
seem to agree about anything is when it comes to Dean. How to
tease him, how to punish him, how to fuck him
whatever
friction there is between them never seems to get in the
way of that. In fact, if anything, the rivalry only makes
it better. Keeps things interesting.
For instance, they get into these little competitions sometimes,
over how many times they can fuck Dean in one weekend, or how
many different ways
Sometimes Dean puts them to the test
too, timing how fast he can make them cum, or how long they can
hold out, or who begs for it first which Cas claims
aint fair since Benny gets to have Dean all the time, so
obviously Cas is in a greater state of need (desperate) for it.
I just aint the beggin type, Benny smirks
back at him.
I see, Cas replies, squinting his eyes dangerously,
and Benny knows its on. I am quite certain,
however, that with a little help from Dean, the two of us could
make you beg, without even touching you.
That so? Benny arches a challenging eyebrow. And
thats how Benny ends up with his wrists cuffed to the
bedposts, Dean on all fours over him, ass just out of reach but
completely on display as Cas fingers him open, tugging on
Deans cock while it hangs hard and heavy between his legs.
Cas keeps that just out of reach as well, no matter how
far out Benny reaches his tongue, and the drippings of
Deans precum land on Bennys chest instead, hot and
wet against his pebbled nipples.
Deans being a total tease about it too, mewling like a
whore as he squirms his hips in front of Bennys face,
squeezing and milking at Cas fingers with his greedy little
hole. But its working. Every filthy moan that spills past
Deans lips, every hungry clench of that soft crinkle, sends
an answering throb through Bennys dick, until soon, he's so
hard he could cut glass.
And here Benny thought he was the one who had the upper
hand in this deal, when Cas said they wouldnt touch him at
all. But really, that little stipulation is working in their
favor, because Bennys pretty sure if either of them laid a
finger on him now, it would be all over Benny
wouldnt even have the chance to beg.
But it seems Cas knew exactly what he was doing when he
made that bet. Seems somewhere along the way, Cas learned exactly
how to push Bennys buttons. And now hes using that
knowledge to devastating effect, expertly working Deans
body like a finely-tuned instrument, designed specifically to
drive Benny into a frenzy.
Benny bites his lip hard enough to draw blood. And as if he
wasnt already fit to burst, thats when Cas climbs
over Benny as well, lining himself up with Deans
well-stretched hole, right in front of Bennys face. But Cas
doesnt push his cock in straight away, no. The bastard. He
just teases Dean with it first, kissing it against that rosebud
mouth, smearing his pre-slick all over the skin of it.
Please, Dean begs, and a small puff of a gasp escapes
Bennys lips, almost forming the word himself. He quickly
bites down on his lip again, determined not to give in at
least, not so damn soon. But it quickly becomes clear that Cas is
going to drag this out, for as long as possible, sliding into
Dean so slowly that by the time he bottoms out, Dean is near
sobbing. And even then, Cas tortures him some more, with the
shallowest of thrusts - just enough to remind Dean hes
there, and what he could be doing with his cock, without
actually doing it.
A veritable waterfall of pleas spill past Deans lips
then, drowning Benny with curses and filthy promises until Benny
is gasping, pulsing and panting with need. And then
finally, finally Cas starts moving, thrusting deep and
long, and pulling back far enough for Benny to see the gaping maw
of Deans hole before he pushes right back in.
And God damn how Benny wants to stick something into that
gape his fingers, his tongue, his dick anything.
And damn Castiel too, because he knows has probably
always known, from day one that Benny is simply incapable
of sitting back and watching. Sooner or later, Benny always wants
in.
Benny looks away. Buries his face into the meat of his arm.
But its too late. He cant erase the image from his
mind. And whats worse, now he hears Deans
pleas all that better as well, the desperation in them, the
groaning need. Now he hears the slick slide of Cas
flesh, thrusting into Deans hole, the soft slap of skin
against skin, Cas balls smacking against that perfect ass.
Dean collapses against the onslaught, pressing his face into
Bennys thigh still remembering to keep Bennys
cock untouched. But hes angled his face so that now Benny
can feel every panted breath across the pulsing heat of his skin,
every groan and every curse, harsh and hot across drooling dick.
Please, please, please, Dean starts chanting
with every thrust, until its the only word Benny hears and
feels and knows. And Benny finds himself groaning, almost wailing,
long and loud and wild anything to drown out the sound of
Deans cries, anything to keep his mouth from actually
forming the words, the only way he can allow himself to voice his
need.
It works. Soon he feels the hot spurt of Deans cum
splashing across his chest, the shudder of the mattress as
Deans body jerks and shakes above him, and Cas
answering cry as he fills Dean up inside. Its over.
Bennys won.
Benny lays there for a long moment, taking deep, victorious
breaths, before he opens his eyes again.
And what he opens them to is the sight of Castiel, tonguing into
Deans ass, that extraordinarily long appendage snaking
lazily into that beautiful gape and coming out drenched
in milky-white.
Holy fucking Hell.
Benny barely blinks as he watches Cas tongue the cum out of that
quivering hole, trails of it stretching between his lips and
dribbling down Deans balls, dripping across his perineum,
and right onto Bennys tongue.
Benny licks it into his mouth without a second thought, and as
his tongue curls the flavour between his lips, his mouth finishes
the movement with a single word
Please.
Its barely a whisper. A mere exhale of a breath. But
unfortunately, Cas face is right above his, angled close
enough to hear it anyway.
Good boy, Cas smirks, lips glinting with the shine of
his own slick. And Benny doesnt know whether Cas is
referring to him or Dean, but he doesnt really care either
way, because then Cas is angling Deans ass down over
Bennys face, sitting him right on Bennys waiting
tongue.
Benny may have lost the bet, but when Dean starts riding his face
in earnest, smearing that sweet cum all over Benny's face and
beard, he feels like he won anyway. Because yeah, Cas cum
may be manna of the Gods, but only when Benny is licking it out
of the Heaven that is Deans ass.
~
Afterwards, when Benny is licking his own flavour out of
Deans mouth, he wonders. What does my cum
taste like, then?
Like the best kind of sin, Dean grins.
And yeah, Benny can live with that.
