'It's wrong. This Sesshoumaru knows this is wrong but we will continue regardless.'

Sesshoumaru peered at the female figure lying on his chest. He absorbed the silence and the feeling of content. His right hand stroked the top of her head. Minutes passed before the figure stirred, slowly awakening.

Her eyes fluttered and she yawned showing abnormally long canines.

She shifted looking at him and slowly crawled up beside his head.

"Good morning, Nii-sama," she whispered and gave him a gentle peck on his lips.

Sesshoumaru placed his left hand behind her neck and pulled her in for another kiss, longer than the last. He nibbled on her lower lip and she obediently opened her mouth for him to explore. Both of them were panting when they separated.

"Morning," Sesshoumaru replied huskily as he slowly stoked her neck.

She sighed and leaned closer to his gentle ministrations, his hand moved down her shoulders leaving goose bumps on her skin from whispering touches.

Sesshoumaru traced the outline of her right nipple watching as she closed her eyes and whined. He knew the touches were driving her crazy with lust. He suddenly stopped his ministrations causing him to stare into a pair of identical golden eyes, so much like his own, clouded with desire.

The young prince gently flipped them over, leaving his sister between him and the futon. His lips followed where his hand trailed before.

The girl beneath him shivered, her mouth parting for air as his lips slipped lower down her body.

He could smell it, her willingness, the growing heat between her legs, his senses were trained on her and only her.

As Sesshoumaru slowly aroused her, he became aware of his own need. His lips travelled back up to her neck and he groaned when she slowly rubbed her legs against his groin.

Sesshoumaru buried his face against her silky white hair and inhaled her citrus-apple scent. He groaned as he entered her slick folds.

Both occupants moaned as their desire increased, a jerk from her hips sent Sesshoumaru growling with pleasure. He could feel her beneath him as she softly panted against his ear.

Her final action sent him over the edge; she was nibbling on his earlobe. Without hesitation Sesshoumaru grinded against her, ignoring her sharp gasp.

He set at a fast pace, grinding every time he thrusted in; he wanted her to receive him to the fullest extent.

Sesshoumaru felt the muscles around his penis clench in an orgasm and he crushed the instinct to mark her as his mate.

He pulled out just before his own release, spilling his seed on the sheets.

Both figures laid panting from their recent activity, Sesshoumaru watched as his sister's eyes slowly began to droop. Just before she fell asleep he caught her whisper.

"I love you, Sesshoumaru."

He closed his eyes as if refusing to acknowledge her feelings, his eyes shone with sadness as he looked at her slumbering peacefully.

Sesshoumaru kissed her gently on the forehead.

"Sleep well, imouto."

Then he too fell asleep.

Authors note: With this story I was exploring the realm of romantic love between siblings...

I know there have been real cases of incest in society but as spectators and outsiders, we don't really know if it is real love or abuse.

Is it really wrong? I'm not talking about genetic wise, because it has been proven that deformed children are very likely between two parents who have similar DNA markers. If the bible is true then Adam and Eve's children all married each other...that's incest.

Well, this story was to satisfy my curiousity in that realm. Also I don't really see Sesshoumaru with a love interest... Loving a his twin...would this be a form or narcissism?

I hope you enjoyed the story.
