"Do you love me, Cissy?"
Narcissa opened her eyes blearily. She had been almost asleep, and Bellatrix just had to come wake her up…
"'Course I love you, Bella," she mumbled.
"How do you love me?"
She rubbed sleep from her eyes, shaking her head a little. The room she shared with her sister was dark, and Bellatrix, kneeling on the foot of the bed, looked quite eerie in the moonlight that filtered through the curtains.
"What do you mean?"
"How do you love me?" Bellatrix repeated. "Do you love me like a sister, or do you love me in every way there is?"
Yawning, Narcissa shook her head. "I don't know… how can I tell?"
Bellatrix smiled slightly. The pale glow from outside made that little smile look almost sinister, and Narcissa found her heart pounding a little.
"Well," Bellatrix said slowly, "there is a way of telling… you see… there's something I can do to you, and if you don't like it, then you only love me like a sister, but if you do like it, then you love me in every way there is."
Narcissa shrugged a little. "All right, then. What are you going to do?"
The smile that had formerly seemed slightly sinister now looked downright wicked. Bellatrix stood up from the bed, hurrying to her own bedside table. She picked up her wand, then rifled around in her drawer, biting her lip.
"Ah, this'll do," she murmured at last, picking up something small and cylindrical. Squinting in the dark, Narcissa recognized it as a lipstick tube.
Returning to the bed, Bellatrix tapped her wand against the tube of lipstick, and it started vibrating. Narcissa shivered, looking at it warily. "What's that for?"
"Well…" Bellatrix's voice had turned from its usual tone to a strange, sensual purr, "I can't very well leave a proper vibrator lying around, so I have to do my best…"
Narcissa's heart fluttered. "What?"
"Shh…" Bellatrix leaned forward, gripped one of Narcissa's knees in each hand, and spread the younger girl's legs apart. Narcissa let out a little gasp and her legs automatically clamped together. "What are you doing?"
"Don't worry, Cissy," Bellatrix said impatiently. She leaned back, narrowing her eyes at her little sister. "Do you think I don't know what I'm doing? Because I do. So just relax and let me work."
Narcissa bit her lip, and reluctantly relaxed again. Her cheeks burned as Bellatrix's hands travelled up the insides of her thighs, lifting her nightdress, and her long fingers probed around between her legs.
The soft purr of Bellatrix's voice relaxed Narcissa slightly, but then she felt something cool and foreign slide inside her body. She cried out in shock, clenching around it.
"Relax!" Bellatrix commanded. She was still probing, and the cool thing was moving even deeper inside Narcissa, and she could feel it shaking and vibrating. Her heart almost stopped as she realized that Bellatrix had put the lipstick tube into her, and she squirmed nervously.
"I keep telling you to relax, dammit," snarled Bellatrix. She sat back again, and pulled her nightdress off over her head.
Narcissa's eyes fell automatically on her sister's breasts. They were so often concealed under the tight fabric of her corsets that Narcissa didn't think she had ever seen them loose before. And they were big… bigger than she had thought they would be…
A tiny throb went through her. The lipstick tube vibrating inside her was starting to feel good…
Bellatrix noticed Narcissa's eyes on her chest, and she smirked. "Do you like my tits, Cissy?" she purred, cupping them in her hands. The words sounded strange in Bellatrix's mouth, but her mind seemed blurry and she couldn't quite register how strange it was.
Narcissa's hands moved automatically to her own chest. Bellatrix twisted her nipples between her fingers, and Narcissa copied her, pinching herself.
"That's a good girl," Bellatrix murmured. "Feels good, doesn't it?"
Narcissa nodded, squirming now. The pressure between her legs was growing and she felt moisture dripping out of her as the tube moved inside her.
Bellatrix leaned over her little sister, pressing her breast against her sister's mouth. Her hand travelled down Narcissa's flat stomach to between her legs, and Narcissa jumped as a finger rubbed against her aching clit. The vibration inside her was becoming unbearably pleasurable, and Bellatrix's breast against her mouth, and her finger rubbing against the most sensitive part of her–
Narcissa let out a cry. Her back arched, her legs bent up until her knees were almost next to her ears and she writhed underneath her sister. Stars popped in front of her eyes. She was quite dizzy with ecstasy as she gasped for air.
At last, the feeling subsided, and Bellatrix pulled the lipstick tube back out of her.
"Nice, wasn't it?" she breathed.
Narcissa nodded helplessly.
"See," Bellatrix continued, "I wasn't lying when I said it was a good way tell how much you loved me. Don't you feel like you love me even more now than you did before? In every way you can?"
Again, Narcissa nodded helplessly. She did love her sister in every way she could, and what her sister had just done to her only made her love her more.
Bellatrix climbed out of the bed, and went to her own, turning over so her back was to Narcissa. Narcissa lay in her own bed, gazing at Bellatrix in the pale moonlight.
She tried not to think that Bellatrix had never said she loved her.
