He was a smooth furred neko. His muzzle was a soft white, but most of his hair was a rich dark brown. He kept it clipped somewhat short, not that it really needed it. He was a natural short hair was it was. His paws were the same soft white. Even his ears were dark brown, with white tufts. But the dark hair on his head also covered most of his body, unlike his younger sister. He could picture her even now. While her paws were white like his, this they shared in common, her body more closely resembled a human female.The lack of fur above her wrists and ankles, rough skin instead of a smooth coat. She covered herself instead in clothes that fit her form. Her hair was a rich dark reddish orange, and her ears, those of a neko, were of a similiar shade. Often she woke him up in the strangest of ways. Even now, he could almost hear her voice calling him by name.
He woke up in his bed to his younger sister naked, on top of him, under his sheets. "W-what are you doing!?"
She tried to snuggle down on him. "I was cold, and you're realty warm!" She says simply, in a soft voice.
"B-but why are you naked!?" He struggles, trying to move.
She only tries to snuggle him more, pressing down on him, as he tries to move. "B-But isn't that how you get the warmest?"
"B-b-but you're my sister!" He looks away and has to think, wondering what would be the best thing do to. He'd secretly fancied her for well, since he could remember..He stares deeply into her eyes, then kisses her deeply, running his hands down her body and grabbing her ass tightly. "You naughty girl."
She blinked once, staring into his eyes as she kisses him just as deeply in return. She blushes as he ran his hands down her body, and grabbed her ass. She reaches up slowly with her own hands, to glide them up his body, then back down, to give his waist a soift squeeze. "How am I naughty?"
"Well you're my younger sister, and your naked on top of me in my bed..." He continues kissing her, and grabs her ass tighter, his cock throbbing for her pussy.
She keeps kissing him in return, and moves her legs so she would be straddling him, as she looks at him. She softly caresses his sides, as she says. "But isn't this what I'm supposed to do?"
