Tsukune and Moka were in the living room watching television as his mom entered the room. "Tsukune, there's someone here to see you."

Tsukune looked up unalarmed figuring it was likely an old friend from the neighborhood. "Oh? Who is it kaasan?" When he saw Ria step up beside his mother he felt his blood grow cold. "Ria what are you doing here?!" He jumped to his feet.

The pink haired Moka got up as well, every bit as alarmed. "Sister?"

Mrs. Aono looked at her guest in surprise. "Ah! Are you Moka's sister?"

Ria nodded politely. "Oh me, oh my I certainly am. I am her big sister."

Mrs. Aono gave her a welcoming bow. "I am very pleased to meet you, welcome to our humble home."

Ria smiled sweetly. "Well it certainly is humble."

"Eh?" Mrs. Aono looked at her questioningly.

"Mom, could you make us some tea and maybe some cookies?" Tsukune asked. He carefully stepped between his mother and Ria. "I think Moka and I would like to talk to Ria alone for a bit."

"I would like that brother dear."

"Brother?" Mrs. Aono said in surprise.

Ria turned to the woman. "What? Hasn't Tsukune told you about how my father has welcomed him into the family? Even though there's been no wedding he already sees Tsukune as a son, and of course I think of him as my very own outoto."

"Well how lovely! Tsukune why didn't you tell me you'd grown so close to Moka's family?"

"It must have slipped my mind," Tsukune murmured.

Ria wagged a finger at him. "You're so naughty Tsukune, forgetting about me like that." A cruel sparkle filled her dark eyes."I haven't forgotten about you brother dear, oh no not for a moment."

He grabbed her by the wrist and began leading her to his room. "Mom please excuse us."

Moka followed them while his mother went to the kitchen to make the tea and cookies.

"So this is your bedroom!" Ria said. "It's rather bland, but not too bad considering it belonged to a human." She immediately laid out on the bed. "Mmmm, comfy," she smiled over at him. "Care to join me brother dear?"

"Don't be disgusting!" Moka hissed furiously. Apparently her moral code did not extend to her sister openly flirting with him.

"What are you doing here Ria-san?" Tsukune asked.

"Awww, do I need a reason to come and visit my darling outoto and imouto?" She pouted a bit.

"You haven't come here just to visit," Moka said sternly.

Still lying on his bed she propped herself up with her elbows. "You know brother dear when we first met I wondered why you cared so much for the humans. Now of course it's obvious, being a former rat yourself it's natural that you would sympathize with your fellow vermin."

Tsukune and Moka shared a nervous look.

Ria pretended not to notice and continued. "I don't care of course, in my eyes you are a vampire now. What you were before doesn't matter. Father on the other hand is a bit old fashioned about these sorts of things. If he were to find out the truth he would be insulted. He might take out his anger on you… and on your whole family."

"Are you threatening me?" Tsukune said angrily.

Moka placed a restraining hand on his arm. "What do you want Ria? If you just wanted to tell father you would have. Obviously you're after something else."

Ria grinned merrily. "Oh me, oh my that's true. I do want something in return for keeping Tsukune's little secret." She looked directly at him and slowly licked her lips. "I want to share."

Moka gasped and paled.

Tsukune looked questioningly at her and then back at Ria. "I don't understand, share? Share what?"

"You," Ria said sweetly.

Mrs. Aono had just finished brewing the tea and putting a tray of cookies in the oven when she saw Ria and Tsukune enter the kitchen. She thought her son looked a little pale and nervous. Ria by contrast seemed in fine spirits. She had a hold of her son's arm and her head was resting lovingly on his shoulder. She thought it very sweet that Moka's sister was being so affectionate towards him.

"I thank you for inviting me into your plain and ordinary home," Ria said. "But I need to go; I hope you don't mind if I borrow Tsukune for awhile? I promise to return him after I'm done."

Tsukune seemed to go even more pale.

Mrs. Aono looked horribly disappointed. "Do you really have to leave so soon? I was looking forward to getting to know you."

"Oh me, oh my that's no problem at all! I intend to see lots of your son! In fact I've reserved a hotel suite for hew next few weeks."

"If you like I'm sure we could make room for you to stay right here."

Ria laughed at the thought of that. "No, I think I'd be better served staying at a hotel. It provides much more room and privacy. But I'd like very much to get to know you and your husband. Why don't I return with Tsukune tonight and we can all have dinner together, it will be my treat."

"My dear there's no need for you to pay, why don't I make dinner and we can all eat together right here."

Ria eyed the kitchen and the kitchen table with a critical eye but nodded. "That would be quite… interesting. I look forward to it." She began pulling at his arm. "Come on Tsukune I have lots of things for you to do."

True to her word Ria had reserved the Imperial suite at the Sakura Hotel. The suite was larger than Tsukune's home. As soon as they had entered Ria had eagerly taken his hand and led him into the bedroom. Seeing the large luxurious bed Tsukune swallowed fearfully.

Flashback

Moka lowered her head. "Very well," she said in a hoarse whisper.

"Oh goody!" Ria grabbed a hold of his arm possessively. "I can't wait! Let's get going Tsukune."

He stared at Moka in total disbelief. "Moka-chan! What are you saying?"

"I hate this Tsukune," she said miserably. "But it's the only way to protect you and your family. If you don't agree she'll tell father and I have no idea what he'd do."

"There, it's all settled then!" Ria dragged him from his room unwilling to wait.

Moka stood there miserably and watched her sister take him away.

"Ria-san you don't want to do this," he told her.

"I don't?" Ria looked up at him curiously and tilted her head tot eh side a bit.

"No, you don't," he said. "I know you and Moka have some deep seated issues between the two of you and there are hard feelings. But she is still your sister. I am sure that deep down what you really want is to make peace with her so you two can finally get along like really sisters should. You're her neesan, I know that you don't really want to do this to her."

Ria stopped and stared up at him. "Do you really believe that Tsukune?"

He nodded solemnly. "I do."

She put her head back and roared with laughter. "Hah! Hah! Oh but you're so cute when you're being all trusting and wide eyed! Like a little forest animal! Oh me, oh my I think I could eat you right up! In fact…" with both hand she threw him roughly onto the bed. "I think I will!"

She grabbed her rosario and threw it across the room. Surrounded by demonic power she climbed on top of him and held down his hands roughly by the wrist. Still in his human form Tsukune was powerless to do anything at all. Looking up into her cruel and inhuman red eyes Tsukune felt real fear. It was the same fear any human might feel facing a hungry vampire.

"You… you don't want to do this Ria-san."

A heartless grin exposed her fangs. "Oh I think I do," she purred and leaned down to place her mouth by his throat. "This and a lot more, I am making you mine tonight brother dear."

"My heart belongs only to Moka."

Her laughter tickled his neck. "Oh me, oh my it's not your heart I want." She bit down savagely and let the sweet blood fill her mouth.

Tsukune cried out in pain.

That only gave her even more pleasure. Even if it was only his body, she would make him her own.

All alone in Tsukune's room the pink haired Moka wept.
