Sister My Sister

Lelouch knew he should be disgusted himself.

Decent brothers didn't do this with their precious little sisters, after all. He wasn't, however. He wasn't ashamed. How could he? His love for Nunnally was what kept him going. It was pure, unfiltered adoration.

Pants fell from his mouth as he drove his cock into her tight cunt. The small girl's sweet moans rang throughout her bedroom as she clung to her big brother. Her nails raked down his back and left angry red trails in their wake. Needily, oh so needily, she whimpered and whined for him to please continue.

"Nunnally," he whispered in between feverish kisses that decorated her eyelids, cheeks, lips, and neck. His hands gently trailed along her frail body. His touch was so light that one would think she was made of fragile glass that would shatter at the faintest tap. "Nunnally, fuck, Nunnally..."

Her walls gripped onto Lelouch's prick, as if her body was hungry for his seed, while she wailed in sheer bliss. Desire for more panged across her body. Oh, how she ached for him all day. How she ached for him to treat her like any other girl.

"Harder, please, Lelouch," she murmured into his ear. "I can take it. I promise."

He hissed. Unable to take it anymore, he did just that. Slow but powerful thrusts sent ripples across her subtle curves and had Nunnally see flashes of colours behind her heavy eyelids. Another whine escaped the poor girl as his cock throbbed heavily against her bare walls. That throbbing grew quicker as he grew closer to release. Shuddering, Lelouch drove himself deep inside his sister. Flush against her, his balls thumped against her pert ass as he slid a hand between them. Slow, careful circles were drawn on her stiff clit as he painted her insides with his semen.

"Lelouch...!" she cried. Her back arched against the bed. Tremors wracked her lithe form as he continued to roll the bundle of nerves under his touch. The overwhelming sensation, combined with the warmth flooding inside her, was just too much! A silent scream tore itself from her throat as Nunnally came.

The world around them faded to white as they basked in that afterglow. Warmth blossomed inside the siblings' chests as they slowly floated down to earth.

Lelouch smiled as he brushed a curl from Nunnally's face and kissed her eyelids once more before pulling out of her. "How was that?"

"Wonderful," she smiled.
