I lay there in bed, another sleepless night. I crawled out of bed and grabbed my wand.
"Lumos" I muttered, and the room was lit up.
I tiptoed out into my sister Bellatrix's room, and she was sitting on the bed in just her bra and panties, almost as if she was waiting for me.
I sat down next to her, brushing my hand against the soft ivory skin of her arm.
"What are you doing up this late, Cissy? I'm going to have to punish you" she said, her hot breath on my neck, sending shivers up my spine.
I smirked. "What are you going to do, Bella?"
"I think I could show you better than I could explain it" and with that she kissed me deeply and hungrily.
I thrusted my tongue into her mouth and flicked it against hers.
She grabbed my breast harshly, and I moaned into her mouth.
"Mmm, Bella, I want you" I moaned breathily.
At this, she tore my bra off, throwing me on to the bed. She rolled my nipple through her thumb and index finger, and suddenly I felt her hot tongue swirl around it.
Her teeth bit softly, causing me to cry out in pleasure. I grabbed her long dark hair and threw my head back in pleasure.
"You like that don't you? You're a filthy little whore for a sister." she said, smirking at me, kissing her way down my stomach and sucking gently on the delicate skin there.
She stopped when she got to my thighs, teasing me.
"Mmm love, don't tease" I moaned.
She immediately spread my legs, and ripped my panties off with her teeth. Then she thrusted two fingers inside me, causing me to scream in pleasure.
I felt her hand slap across my face. "Shh Cissy, we don't want anyone to hear, do we?" she snarled, smirking at me. She began to thrust her fingers hard and deep inside me, and suddenly she licked at my clit.
"Mmm fuck!" I moaned, arching my back.
Bella shoved a third finger inside me, and rammed them as hard as she could, sucking at my clit. I bucked my hips against her face, wanting nothing but to cum.
"Harder!" I cried out, and Bella shoved her forth finger inside me, and bit my clit softly. I began to shake, my walls clamping around her hand, cumming hard.
"Bella! Mmm fuck!" I screamed.
She licked the cum off my pussy, and removed her hand and brought it up to my mouth, letting me taste my own juices.
"You liked that didn't you, whore?" she asked.
I nodded, panting hard, coming down from the orgasm.
A smirk came across my face, and I rolled over on the bed, so I was on top of her.
I cupped her large, supple breast in my hand, sucking and biting at her nipple.
"Oh Cissy!" she moaned.
I kissed my way down her stomach, exploring every part of her skin with my tongue. I kissed down right above her panties and stopped.
She snarled and grabbed my blonde hair. "Don't tease me, Cissy."
I ripped her now very wet panties off and threw them on the floor. I plunged my tongue into her pussy and she cried out in pleasure. I replaced my tongue with three of my fingers and rammed them hard inside her, and suckled at her clit, biting it softly.
I wanted to feel her hot cum in my mouth so badly, to taste her. I pumped my fingers inside her faster, and she moaned loudly.
"Mmm don't stop Cissy! Fuck me harder!" she screamed, and I was happy to comply with her request, rammed my fingers in her as hard and deep as they could go, still sucking and biting at her clit.
She screamed loudly, cumming hard. I licked her juices off her pussy and my fingers.
"Mmm, you taste so good Bella." I said, and kissed her on the lips, letting her taste herself.
She panted hard, coming down from her orgasm.
"Oh Cissy, that was fantastic." she said breathily.
"I could say the same for you" I said, and we fell asleep laying next to each other, my head resting on her shoulder.
