"You're being very antisocial, little cousin,"Bellatrix remarked lightly as she stepped into Sirius's room, closing the door behind herself."Downright rude, one might say."

Sirius looked up as she spoke but made no move to get up from his armchair or even lower the book he was reading, instead merely smirking at her."As if anyone minds that I'm not staying for more than dinner these days. We all know not even Mother can stand having me around. And I know you're all dying to discuss the so-called Dark Lord. Hardly a good idea with a potential blood traitor present, I dare say."

"Well, aren't you sharp-witted!"his cousin replied, a smile spreading across her beautiful face as she crossed the room and came to a halt right infront of his chair."But you're being quite hard on yourself, Sirius, dear. Personally, I rather enjoy having you around."

He raised an eyebrow at her, suddenly finding it inexplicably harder to breath regularly."Oh? Is that so?"

"Yes, I think you're fun,"she said, a mischievous glint in her eyes. And with that, she plugged the book from his hands, carelessly tossed it aside and straddled him. Her breath was hot against his skin as her lips lightly grazed his ear."How about we find out just how much fun you can be?"

Sirius knew full well that he ought to push her off; his brain was screaming for him to do it, every fiber of his rational mind demanded it, yet his hands somehow refused to do what he wanted them to and instead came to rest on Bellatrix's hips, caressing her through the soft, cold fabric of her dress.

She smirked, trailing kisses along his neck, slender fingers moving to unbutton his shirt.

Sirius bit his lip, forcing himself to form a coherent thought.

"Bella,"he said, annoyed to find her name rolling from his lips in something painfully close to a moan. She gave a high, clear laugh and it sent shivers down his spine."Bella. This is wrong."

"And why might that be, Sirius?"she breathed, her fingernails lightly scraping against the naked skin of his upper body. He let out a shuddering gasp, just about stopping another moan from escaping his lips.

Her hands wandered over his body as she continued to whisper into his ear, nipping at his ear lobe every now and again."Because we're cousins? Because you're underage? Is it because I'm married? Because my husband's downstairs?"

"That about sums it up, yeah,"he mumbled, pulling her closer nonetheless and not quite able to keep himself from smiling. He could not think anymore and, quite frankly, he did not want to either.

She smiled at him, burying her fingers into his hair. Her grey eyes, so much like his own, were unmistakably clouded with lust as she leaned in, her face mere inches from his."I think you will find that forbidden fruit always tastes sweetest, cousin dearest."

And as her lips crashed onto his in a passionate, demanding kiss he found it very difficult to disagree.
