In this story, Remi and Flan are twins. They're still vampires though XD. This contains (probably poorly written) masochism, only a little bit however.

Flandre turned in her bed, debating whether to make an advance on her sister. Because Remilia had said she loved Flan. She got up and stretched. She slowly made her way down the hall and reached Remilia's room. She tapped on the door, waiting for a response. None came, so she entered the room quietly. She saw Remilia laying sideways in her bed, sleeping peacefully. Flandre hesitated, admiring her sister's beauty. She leaned in to Remilia's face and kissed her forehead. Remilia's eyes opened slowly and stared at Flan's red ones.

"Flan." Remilia said.

Remilia moved her hand and moved Flandre's hair away from her face. She stroked her cheek. Flandre leaned in and kissed her, but Remilia pushed her away after a few seconds.

"We can't be together. It's not right, Flan." Remilia's face was red as well as Flandre's.

"I know... but, I really love you sis." Tears filled Flandre's eyes.

Remilia wrapped her arms around Flandre and pulled her into the bed. "It's okay. Don't cry." She rubbed her twin's back. Flandre shuffled and lay on top of Remilia, staring down at her. "You know that was my first kiss, Flan." Remilia smirked. Flandre smiled.

"We can be together, we just need to keep it a secret." Flandre whispered. She leaned down to Remilia's pale neck. Her eyes flicked up and met Remilia's matching red orbs. "Can I..." She murmured into Remilia's neck.

"Yes, Flan." Remilia replied heatedly.

Flandre's fangs slid out of her gums and she bit into her sister's neck, instantly drawing blood. Remilia cringed, and then it grew into a smile. She exhaled roughly. Flandre flicked her tongue into the fang marks, making Remilia grunt. She lapped up the dripping blood and licked her lips, her red, dripping fangs wound in a smirk. She brought her head up and pushed her mouth onto Remilia's. Remilia tasted her own blood on Flandre's tongue. Remilia bit Flandre's tongue, drawing blood and sucking it away. Flandre's tongue glided over Remilia's teeth slowly. Remilia dragged her hands up Flandre's sides and gripped her shoulders. Remilia slid Flandre's nightshirt up and rubbed her twin's prepubescent breasts. Flandre's wings extended and flapped with the tugs and pulls of her sister's hands. Flandre broke the kiss and cried out.

"Shhh..." Remilia smirked. "You don't want to get caught... do you?" She teased, running a finger over Flandre's lips. "I wonder..." She ran one of her hands on the top of her sister's wings.

Flandre's vision blurred and she yelped Remilia's nickname, which was Remi. She twitched as Remilia ran down the length of her wing.

"Remi! Stop... you're teasing me!" Flandre bucked her hips into Remilia's. Remilia pushed them over, so that she was pushing Flandre down.

"This is how it goes, Flan." She kissed Flandre, her wings opened completely, making her seem very big. Remilia's nightshirt was removed and Flandre roved her hands over her twin.

"You're beautiful Remi..." Flandre whispered, grabbing at Remilia's chest.

"Our bodies are exactly the same Flan." Remilia stroked Flandre's cheek.

Flandre's hands stroked the tops of Remilia's wings, running her fingers through the membrane. Remilia shuddered and fell onto Flandre, her head in Flandre's chest.

"You're very sensitive Remi." Flandre smirked down at her sister, who was limply twitching.

Remilia looked at Flandre's small breasts and took the closest in her mouth, sucking and nibbling on the pale flesh. Flandre cried out in surprised pleasure, tilting her head back. Remilia bit into the sensitive spot, leaving two identical fang marks that dripped blood. She wanted to make Flandre hers. An animalistic instinct took over. Flandre felt it too. She pulled Remilia back down and bit her neck again. Remilia did the same on the other side of Flandre's neck.

This was a vampire instinct. Patchy had given Remilia a book about the rituals of vampires. One section applied to the concept of dual-biting. Dual-biting was when two lovers, during an intimate moment, bit eachother in the same place and sucked on the marks, leaving a mark that is unique to their fangs. This showed a sign of relations and possession. After this, the two would be linked as one for the rest of the moment of intimate contact.

Their wings wrapped around eachother and their bites deepened. Their bodies were pressed together and they were sweating. They stopped biting eachother and looked in eachother's eyes. Their eyes were a dark, shining crimson with lust and possession. Both Remilia and Flandre grabbed the other's breasts and tugged them between their thumbs and forefingers.

"Flandre!"

"Remilia!"

The two yelled out in a white pleasure. Remilia collapsed onto Flandre and Flandre wrapped her arms around Remilia, who's wings were still flapping weakly while Flandre's went limp. The two shared a passionate kiss. Flandre's hand went down to Remilia's lower half, which was soaked from love making. She put her fingers in the spot rubbing it. Remilia shook and groaned. She was still sensitive and she came again, but do to the dual-biting, Flandre came too. Remilia's fingers drew downward to Flandre's heat and coated her fingers in wetness. She brought her fingers back up to Flandre's mouth.

"Suck." She said to Flandre, who took the fingers in her mouth.

Flandre's fingers made their way to Remilia's mouth and Remilia bit them lightly, making her twin moan into her fingers. Flandre did the same, nibbling on Remilia's fingers.

"What was that? Where we bit eachother at the exact same time. It felt good." Flandre said, curled up in Remilia's wings.

"That was something I read in a book. Called dual-biting." Remilia replied kissing the top of her twin's head.

Outside stood Sakuya, who had come because of the noise. She didn't really know what to do, for they probably didn't want to be caught, but first she had to clean up the blood from her nosebleed.
