Summary
     Sirius is 13 and every night he dreams things he is ashamed of when
     he wakes.
Sirius is 13 and every night he dreams things he is ashamed of when he wakes.
He is even more ashamed that they leave him hard and desperate and he cannot
resist reaching down under the covers and finishing what the dreams started. He
bites back the name that's on the edge of his tongue. He knows it's wrong, ever
so wrong. He tries to think of other things, other girls, boys even, anything
else, as he pounds, but the image of his cousin, her crimson lips parted in
laughed or pursed when something has just disappeared between them, will not
leave him and make him feel hotter and harder every second.
He's a bad, filthy, boy; he berates himself as his hand slides up and down
furiously. He does not hear the door open until it is too late. It is her. she
has seen him, seen his body slick with sweat and his hand wrapped around his
hard length. "Bellatrix!" he cries, as he scrambles to cover himself with the
cast aside blankets, trying to sound indignant but her name comes out
unmistakably full of lust.
Bellatrix closes the door behind her as she steps into the room, wearing a
figure clinging, black silk, nightdress that ends about halfway down her
thighs. Sirius tells himself he sound look away but he cannot, and what he sees
does not help the situation he has going on under the blankets any. She walks
over to the bed and strips him of the protection of covers. "It looks like you
could use some help...cousin." she says and the words sound perverted coming
from her lips as she crawls onto the bed and hovers above him.
Sirius knows this is sick and wrong and that he should run, run far away, but
he's been dreaming of it every night for months now and he can smell her, feel
the heat radiating from her skin. Now her lips are on his, sweet and bitter at
the same time, like the taste of pomegranate, its juices running over parched
lips. Her hand is on his, guiding it up the milky white flesh of her leg, up
under the cloth of her dress. By the time he reaches the wetness between her
legs, he does not even notice that his hand is moving all on it's own. Their
mouths separate to explore each other's flesh and before he knows it his is
nudging down the top of her dress, wanting to claim what lies beneath the cloth
for his own.
He cannot reach the skin directly so his mouth continues over it, sucking at
her breast through the cloth, feeling her nipple stiffen in response even with
the fabric between them. She moans and pulls the dress up over her head,
leaving herself as naked as he is. He leaves bright red blossoms under her skin
with his mouth as his fingers move, inexperiencedly but enthusiastically, in
and out of her. Bellatrix recaptures his lips with her own and she lowers her
body down into his, feeling skin against skin, letting him slide into her.
Sirius whimpers her name as his fantasies become realities. Above him she
begins to move, circling her hips and eliciting new and unimaginable
sensations. Sirius' cries become for fervent and are matched by hers as they
thrash on the bed, a tangled heap of ivory limbs and dark matted hair.
He comes inside of her, continues repeating her name, over and over like fading
echoes. They lie there for a while, drained, before she slips away in the
night. It is only after she is gone that it occurs to him that he has just lost
his virginity... to his cousin. Then he looks down and discovers, he isn't the
only one.
