     it, bastard or not.

Merlin has never been this afraid. All he’s ever wanted was to blend in, stay
unnoticed.
“I won’t let them take you,” Arthur says, fierce.
The concern in his eyes makes Merlin’s heart swell with love. He knows his
brother would do anything to protect him, but—
“Even you cannot defy the council.” —he doesn’t dare hope.
“No, I cannot,” Arthur acknowledges, “But what I can do, to save you from being
another senseless sacrifice...”
Merlin lifts his head, looks straight at Arthur.
His brother means to take his virginity away.
They’ve kissed chastely when they were young boys, but... this is different.
Real.
                                      ***
The lights are turned down, setting the room with a dim glow. Arthur grasps his
wrist and pulls him, gently, to the side of the bed.
“Tonight, I’ll make you a man,” he says, his voice hoarse.
Merlin nods. His cheeks are burning with heat. They’ve talked about this like
it’s a necessity, and it is, but he wants it—wants his brother. Wants to see
the flush of his skin as he’s aroused, his eyes as they darken with desire, his
cock, oh fuck, his cock, as it stiffens and peeks out of its hood.
(He’d seen it, once, when Arthur had fucked a serving boy years ago and left
his door carelessly unlocked.)
Arthur helps him unlace his tunic. His fingers brush at his collarbone, warm
and trembling.
Merlin looks up. Arthur’s eyes are hot on him, intense, like he wants Merlin
just as much.
The tunic slips over his head, and his chest feels bare in the cold of the
room. His nipples stiffen, and Arthur’s eyes drop to them, his gaze feeling
like a hot caress.
He reaches out to rub one, gently, then tweak it. Merlin shivers, makes a soft
sound.
“Fuck,” Arthur whispers, “You’re so sensitive.” He pushes Merlin on the bed and
then lowers his head, licking at one, swirling his tongue around it. Then the
other. It’s too much and Merlin fidgets, curling his toes.
“So hot in my mouth,” Arthur says, “little brother.” The reminder makes Merlin
blush. It’s wrong, even if they only share a father, though it doesn’t make him
want Arthur any less.
They start to kiss, and Merlin’s mouth opens under Arthur’s. He uses his
tongue, sloppy and without any finesse, but it seems to affect Arthur because
he moans once, deep and low in his throat. Arthur stops to fumble at their
breeches, fingers clumsy, and Merlin helps, pulling and pulling until the laces
break.
There he is, cock fat and flushed, nestled in coarse, blonde hair. Merlin
stares, transfixed, as Arthur reaches for a pot of salve.
He’s prepared with Arthur’s thick, blunt fingers, pressing in and slicking his
hole, efficient but gentle. It’s not enough; he wants Arthur inside him, and he
tells him so in a voice that sounds shamefully needy to his ears.
“My brother, so hot for my cock, what would the council think?” Arthur murmurs,
teasing. Then he grips himself in a hand, aligns himself, and sinks down slowly
till he’s balls-deep in Merlin’s arse.
This is it, Merlin thinks in hazy pleasure, his brother thrusting deep into
him. He’ll be safe now, now that he’s no longer a suitable sacrifice. The
council will have to find someone else from another family to appease the
dragon. He groans as Arthur comes inside him in warm spurts, and they both
reach between them to bring him off.
                                      ***
“What do you mean he cannot be a sacrifice?” Uther snarls.
“He is no longer a virgin, and the gods must have a virgin,” one of the elders
says, his voice brooking no argument. “We must give the Pendragon girl.”
Uther’s face crumples. Merlin gasps, wondering. It is known that there are only
two blood children, the crown prince and the bastard son, born of a lowly
peasant woman.
“Morgana must take his place.”
The court is caught in shocked silence. The king’s ward!
A sob echos in the hall as she falls to her feet. Merlin cannot help but feel
relieved, and then after, the guilt that he can be this callous.
