Chapter 1

It had been a normal school day for all the students of Raisanagi high school: lessons, lunch, afternoon lessons and then back to home. Though, the young man known as Kiryuu Keiki couldn't consider his day as normal, as after he helped his dear senpai and president of the calligraphy club, Sayuri Tokihara with the help of Mao Nanjo, his kohai Yuika Koga and his sister Mizuha, he found a love letter for him with a pair of white panties.

"I love you, Kiryuu Keiki.", was all that was written on the letter, with no signature or other indications that could tell him who was the girl that wrote it. But what shocked him and even made him blush deeply, was the pair of white panties in his hands, as he couldn't tell if they had been used or not.

'I-It's true that I desire to have a girlfriend so bad, but I didn't expect to receive a love letter like this. But who could it be?', he thought, starting to wonder who was his Cinderella.

Ever since he started his high school student's life, he wished to have a girlfriend and hated seeing happy couples while he had not gone on a date with a girl yet. His best friend and a lolicon, Shouma Akiyama, told him often that he would find a girlfriend sooner or later, and it seemed that the moment was finally arrived.

Though, Keiki had to find out who was his Cinderella now, which was something he couldn't do alone. And who was better than his best friend to help him? No one else.

So, after putting away the letter and also the pair of underwear in his bag, he left the calligraphy club's room and met Shouma at the exit of the school building.

"Hey buddy, you took your time in helping your dear Sayuki-senpai, huh?", teased him the blonde boy, smirking.

"A-ah, yeah, I helped her with Mao's, Yuika-chan's and Mizuha's help thankfully. But never mind that and look at this.", replied the purple haired boy, showing his friend the love letter.

The sight of the letter made his friends gasp. "Wow, you received a love letter? That's amazing, Keiki! But it doesn't have the name of who wrote it.", said Shouma, reading the document.

"Yeah, and it's not the only thing I received. You see…"

Keiki whispered in his ear about the panties making Shouma shocked. "Seriously? Dude, you made the girl fall hard for you then haha. But if you found the letter after Tokihara, Koga-San and Mao left the room, that means that one of them is your future girlfriend."

Keiki blushed and sighed in annoyance. "Ugh, why couldn't she just write her name on the letter? I would date her right away in that case.", complained the young man, making his friend chuckle.

"It's a shame you don't have a loli friend. Finding a girl like that is difficult for me.", joked Shouma, getting bonked on the head.

"Your fetish for loli girls is dangerous for them.", said Keiki before laughing together his friend while walking towards their neighborhood.

The two of them, along with Mao, were friends since middle school and lived in the same neighborhood. Keiki and Shouma made friends easily when they started middle school, and soon, also Mao became their friend and spent various nice moments with them at the arcade or going to bowling.

Shouma was a lolicon because of his twin older sisters that teased him often and even surprised him on a Valentine's day by painting chocolate in their bodies. The result was that he turned into a lolicon that liked girls of his age or slightly older with childish appearance, as he didn't want to go to jail for looking at real kid girls.

But despite his fetish, he was always a good and helpful friend to Keiki, so he didn't waste time in discussing with him on who could be the Cinderella girl. "Mao never seemed the type to have the hots for you, as she would have already asked you out in middle school otherwise. So it's either Tokihara or Koga."

"Hmm, Sayuki-senpai teased me often playfully, but without exaggerating. Yuika-chan seems to be too diligent instead, so I don't think it's her.", said Keiki with a hand on his chin.

"Don't be so sure, buddy. Girls can be perverted too, so one of them is surely attracted to you and wants you as her boyfriend. But she's not ready to tell you that directly maybe.", told him the blonde, putting a hand on his shoulder.

The purple haired boy started to imagine to kiss Sayuki then, blushing and smiling. 'W-wait, Sayuki-senpai c-can't be such a pervert. B-but the idea of her being my girlfriend...', he thought, continuing to imagine the hazel eyes girl kissing him.

"Oho, who are you thinking about?"

Keiki blushed more and shaked his head to deny his friend's implication, which only brought the lolicon to tease him more about Sayuki and Yuika until they reached the young man's house in front of which Shouma greeted before going to his house.

After that, Keiki took the key and opened the door, entering inside while saying, "I'm home, Mizuha."

His brown haired sister came out from the kitchen with an apron upon her casual clothes. "Welcome back, Nii-San. Sorry if I didn't help you to finish to clean the club's room.", she told him, smiling sadly.

"It's fine, don't worry. I managed to finish that without any problem.", he told her, smiling and deciding to not tell her about the love letter; he didn't want other people to know about it.

"I'm glad to know it. By the way, I decided to make some rice with teriyaki sauce and chicken for dinner", she said, smiling brightly.

"Haha, even just hearing the name fo the dish makes it yummy. I will go to take a bath then.", he told her, giving her a headpat that she liked very much before going upstairs towards the bathroom.

Once there, Keiki undressed and filled the bathtub with hot water and soap before entering inside of it and relaxing. 'Nothing is more relaxing than a nice hot bath. Though, if I consider what Shouma said, my secret future girlfriend is either Sayuki-senpai or Yuika-chan. Both of them are beautiful and I get along very well with them, but it's h-hard for me imagine them giving me their underwear like that.', he thought, blushing.

The other people that helped to clean the club's room were only his sister and Mao, but since the first was his sibling and the second would have asked him out way before if she liked him, only Sayuki or Yuika could be the author of the letter. And as he was determined to find his Cinderella out, the young man decided that his first move for that would be to ask Sayuki to hang out together.

The black haired girl with hazel eyes teased him often and was always nice with him, as she was deeply grateful to him for joining her club. Plus, he couldn't negate the fact that he was very attracted to her and liked her caring side, so he was sure that she would be happy if he invited her for a parfait.

'Yeah, that can work. I will ask her out tomorrow while we're alone in the club room. Being the only member of it always gives me the opportunity to spend time alone with her, after all.' he thought, blushing and smiling at remembering the first moments he spent together with Sayuki since he joined the club.

Once he was done with his bath, he put on a t-shirt and some pants and joined Mizuha to have dinner, smiling while savoring the food. "Your cooking is always great, Mizuha. I'm sure that you will find a boyfriend easily like this.", he told her.

"B-but there's no one that I like at school, Nii-san.", said the girl, blushing.

"You will find someone, don't worry. I just hope that he won't be a scumbag that plays with your feelings haha."

Mizuha giggled along with him, making their dinner even funnier. Their parents weren't at home because it happened often they were overseas for work, so the two siblings had to take care of the house by themselves. So Mizuha was in charge of cooking and doing the laundry while Keiki had to clean the rooms and buying groceries, with this one being done together his sisters sometimes.

Of course, the young man was able to cook as well, but it was mostly Mizuha to take care of that because Keiki was busy with the calligraphy club sometimes. And as he was sure to spend some time alone with Sayuki the next day, he was going to be way busier than usual.

The following morning, after waking up and having breakfast with Mizuha, the boy went to school together with her, Shouma and Mao that joined them along the way. "Dude, you seem to be in a very good mood. Are you thinking about your beautiful club president?", asked the blonde boy, making Mizuha pout and Mao frown.

"S-shut up, it's not like I think about Sayuki-senpai that often.", replied Keiki, flustered.

"Kiryuu, what's going on? What's up between you and Tokihara-San?", asked him Mao, looking at him seriously.

"Huh? N-nothing, it's just Shouma teasing me about her.", he said, not wanting to tell about his plans to anyone. Especially the redhaired girl that looked jealous.

"Hmm, I see.", said the girl, pouting and walking more ahead of them.

Both Keiki and Shouma were surprised by her behavior, with the first guessing that she was jealous of Sayuki perhaps. On the other hand, Mizuha continued to pout after hearing about her brother and the hazel eyes girl, but Keiki didn't notice it.

Anyways, the group continued to walk until they reached their school, with Keiki and his friends going to their class while Mizuha went to hers. In their class, Shouma attracted the eyes of various girls, even if he didn't pay attention to them because he had eyes only for legal lolis.

Keiki just sat at his desk instead, taking out his notebooks to be ready for the lesson. He noticed that Mao avoided to look at him in the eyes, keeping the frown that she had earlier. 'No, it can't be. Mao can't be jealous of Sayuki-senpai, otherwise she would have asked me out way earlier to make me hers.', he thought, shaking his head and negating the possibility that she liked him.

What concerned him more now was inviting his beautiful club president for a parfait and ask her about the love letter to see if she was his Cinderella. As far as he knew, Sayuki didn't interact with other boys but him, which fueled even more the chance that she had feelings for him.

And his mind started to imagine himself and the girl as a couple, making him smile and blush while remaining oblivious to Mao glancing at him with a huge pout. 'Stupid Kiryuu.', she thought, looking away and frowning while he continued to imagine of becoming Sayuki's boyfriend.

The morning lessons and lunch time went fine for the young man and his friends, and during the second, Yuika and Mizuha joined Keiki and his friends to have lunch. "Keiki-senpai, why are you smiling so much?", asked the petite blondie out of curiosity.

"Oh, nothing, Yuika-chan. I'm just in a good mood.", he replied happily.

"He's thinking about Tokihara. Ow!", said Shouma before getting bonked by his friend. Upon hearing that, Yuika gasped and frowned in jealousy.

'Why does Witch-senpai attract him that much?!', thought the young girl, totally jealous. Mao and Mizuha pouted instead, not liking hearing about Sayuki again.

Of course, Keiki didn't see their expressions because he tried to stop his best friend from teasing him again, managing to do it before returning to eat. Though, he saw that Yuika was frowning, so he asked her what was wrong.

"I'm fine, Keiki-senpai.", she replied, pouting.

"Are you jealous of Sayuki-senpai maybe?", he asked her, smirking.

Blushing because he saw through her, the petite blondie quickly finished her meal and left the table, making Keiki sweatdrop.

"So you like teasing your kohai haha."

"Nii-San, that wasn't very nice.", scolded him Mizuha, frowning.

"I just teased her a little, come on.", he complained, still smiling. Mao pouted instead and didn't say anything, even if her jealousy didn't diminish at all.

Once lunch time was over, every student went to each own class for the afternoon lessons, with Keiki looking forward to go to the club's room later. Still, he thought about Yuika's expression of earlier, which made him blush.

'I was right, she was jealous of Sayuki-senpai. But I guess that it's expected, since I insisted several times on becoming Yuika-chan's friend haha.', he thought, reminiscing how the young girl warmed up to him months ago after he tried to make friends with her in the school's library.

While she ignored him during his first attempts, she began to chat with him and dropped her cold attitude in exchange for a more cheerful one. Though, Keiki knew that she didn't like that he spent time alone with Sayuki, which proved his point of her being jealous of the club president.

He considered Yuika as one of the cutest girls he had even seen, but Sayuki had her charm and he was affectionate to her. Plus, if she happened to be his secret future girlfriend, he would gladly become her steady boyfriend. He wanted to have a girlfriend so bad, even if she was perverted. After all, it wasn't like he was a normal guy.

The lessons went well until the very end, so Keiki greeted Shouma and Mao before walking towards the club's room. Once he was in front of it, he opened and smiled at seeing his dear senpai busy with writing something on a large piece of paper with a paintbrush.

Hearing the sound of the door, the girl turned around and smiled at seeing her dear kohai. "Ara, welcome back, Keiki-kun. I felt lonely without you here hehe.", she told him, giggling.

"It's my duty as club member to come here, Sayuki-senpai. What are you writing?", he said, putting down his bag and getting closer to her.

"I was trying to ameliorate my calligraphy. I must set the good example as club president."

"But you write really well already to be honest.", he told her, making her blush a bit.

"T-thank you. Hehe, you like teasing me perhaps? You always make me blush with your compliments.", she said, smiling at him.

"Haha, maybe yes. Anyways, I wanted to ask you something."

"Ehh? What is it, Keiki-kun?"

"After the club's activities, w-would you like to go to eat a parfait together?", he asked, blushing and scratching the back of his head.

His words caused Sayuki to blush more than him and gasp, totally surprised by his invitation. "Y-you mean that you want to hang out together like we were on a d-date?", she asked him, playing with a length of her hair.

"Y-yes, but If you don-"

"N-no, I would like to of course! I like spending time with my cute kohai.", she quickly interrupted him, blushing but teasing him anyways.

Her teasing move had its effect because Keiki blushed and smiled, even if the girl was flushed as him. He didn't want to ask her about the love letter right away, but after their date, he would surely do.

Since she accepted his invitation, the boy joined her in trying to ameliorate his calligraphy for what concerned kanjis, sitting very close to her. Both of them were still a little flustered, but that didn't stop them to tease each other playfully like they always did.

'Keiki-kun has just asked me out…Hehe, it looks that my wish is close to become a reality.', thought Sayuki, glancing at him and smiling while he was writing. She wanted to tell him her secret, but it was better to do it after their date; enjoying a parfait with him came first, after all.

The two teenagers continued the club activities for some hours, after which, they decided to leave the school to go to eat a parfait together. Thankfully, all of Keiki's friends and even Mizuha had already gone home, so he didn't have to worry about being seen by them.

"So, where did you want to eat a parfait, Keiki-kun?", asked him the girl, smiling at him.

"I-I know a new cafè that has recently opened and it's pretty popular for his desserts.", he replied, blushing and scratching his cheek.

"Really? Hehe, you really wanted to go out with me.", she told him, giggling and not keeping any distance from him.

The young man blushed more because of his words, but he was happy that she looked forward to hang out with him. The place wasn't too distant from Raisanagi, since Keiki checked it up by using Google Maps on his phone, so the two of them didn't have to walk too much to reach it.

During their walk, Sayuki's attention was caught by a white dog being scolded by its owner for having peed where he couldn't. "Hmm? Do you like dogs, Senpai?", asked Keiki to the girl.

"A-ah, yeah. I found it cute when that woman patted her dog on the head.", she replied, blushing. She also came up with an idea.

"Keiki-kun, could you pat my head please?"

"Huh?!", was his reaction, accompanied by a blush.

"I w-want to know what being patted on the head feels like, please.", she said, using a puppy look that hit his heart deeply.

Unable to say no, he complied and patted her head lovingly, making her blush and smile. "Thank you, it feels really nice.", she told him happily.

"Glad to hear it.", he said instead, liking her happy expression. Whenever he saw her smiling, she was really too cute.

And after that sweet gesture, they walked a little more and arrived to the cafè, entering inside of it and sitting at a table where they ordered two parfaits. While waiting, they chatted a bit about school and similar stuff, getting surprised by how delicious the desserts looked once the maid brought them to the table.

"Wow, this looks so tasty! You were right about this place's popularity, Keiki-kun.", said Sayuki, happily starting to eat her parfait and giggling.

"I'm happy that you like it. You're even more beautiful when you smile like that.", he told her, grinning.

"H-huh? J-jeez, you make me blush too easily.", she told him, blushing and looking away.

"It's your fault for being too cute, Senpai.", he said, enjoying how he teased her and made her blush more. The fact that she liked being praised teasingly like that made it even better.

Some maids giggled at seeing them act like that, thinking that they were a cute couple. They also gasped when Keiki tasted Sayuki's parfait, saying that it was sweet like she was with him.

'K-Keiki-kun is indeed the boy I was looking for.', thought the young girl, still blushing and smiling nervously. She was already happy when he asked her out, but the fact that he teased her like that made her overjoyed.

'Sayuki-senpai is certainly the girl who wrote that letter. Her reactions to my teasing are typical of a girl in love.', he thought instead, smiling. If Sayuki was indeed his Cinderella, he was ready to become her boyfriend.

The two teenagers finished to eat their desserts after a while, so now they were out of the coffeehouse while walking and chatting. Feeling that it was time to find out if she was the author of the letter, Keiki suggested to the girl to enter in a park to relax, getting a nod in return.

Inside said place, they sat down on a bench, with him taking a deep breath and saying, "Sayuki-senpai, t-there's something very important I want to ask you."

"Huh? W-what?", she asked, blushing profusely.

"You see, yesterday I found this anonymous love letter for me in the club's room after you and the others left. So I wanted ro know if y-you're the one who wrote it.", he replied, shocking her.

'N-no way…Someone else likes Keiki-kun?!', she thought, getting angry at the idea that someone could take the boy away from her. But she managed to calm down herself before giving him a reply.

"I-I see. I'm sorry, but I didn't write that love letter.", she told him, making him gasp and frown.

"Really? I hoped that it was you.", he said, making her eyes shine.

"I-I may not be the letter's author, but there's something you need to know, Keiki-kun. C-could you close your eyes, please?"

Her words caused him to gasp and blush, thinking that she was going to confess. It was like he thought; Sayuki was attracted to him and liked him, so this was the famous confession moment where the maiden in love would kiss the boy she loved.

Smiling, he complied with her request and closed his eyes, getting ready to be kissed by his dear senpai. Though, after 2 minutes, Sayuki told him to open his eyes and when he did so, they widened at seeing her with her school's shirt unbuttoned and a dog collar around her neck.

"K-keiki-kun, I like you. Please, be my master~!", she told him, smiling perversely and blushing.

"W-what?! What's the meaning of this?!", was his reaction upon hearing her words. He expected a confession followed by a kiss, but not something like that.

"I know you're confused right now, but the truth is that I like you and I want to be your pet~!", she told him, offering him the handle of her collar.

"Wait, does it mean that when you looked at that dog, you-"

"Yes, I was envious of that dog for having an owner that scolded him and patted him. When you said that you received a love letter, the idea of losing you to another girl ticked me off.", she told him, getting close to him and looking at him deeply in the eyes.

"P-please, make me your pet, Keiki-kun~.", she told him, smiling.

The young man couldn't avoid to be stunned and flushed by her particular confession; he never imagined that his dear senpai was a masochist that wanted him to be her master, but hearing that she liked him and that didn't want to lose him to another girl made his heart flutter.

So, looking away to avoid to gaze at those softs mounds of meat on her chest, he said, "I-I'm sorry, but I can't give you an answer right away. I suspected that you liked me, but not that you were like this too."

Sayuki was shocked and a little sad because of his words, but hearing right away made her eyes shine. "D-does it mean that I can still become your pet?", she asked him.

"I'd prefer you said girlfriend, but y-yeah. A-after all, I have always been ttracted to you.", he told her sincerely, causing her to smile more and giggle.

"Yatta! I will do my best to make you fall for me completely then, Keiki-kun~.", she said, giving him a lick on the cheek that made him blush deeply.

"W-what was that?!"

"Hehe, dogs like marking their territory or the things they like. So that was me marking you as my future owner, Master~.", she told him, licking her lips and giggling.

'Oh boy, I guess I will end in various complicated situations from now on.', thought the young man, still flushed but liking what she did. It kinda teased his other side, after all.

Since it was getting late, Keiki decided to accompany Sayuki back to home, making her smile and thank him for being so caring. She also added that it was another side of him that made her want him as her owner even more, causing to blush embarassed.

So he walked with her towards her house, getting to enjoy the softness of her breasts due to her clinging on his arm. He was surprised by her sudden clinginess, even if, considering her confession and what she told him, he saw it coming.

Despite she wasn't the one to have written that love letter, he was happy to know that she had feelings for him anyways. Perhaps they were twisted because of her unexpected fetish, but that didn't mean it annoyed him. Besides, the fact that she liked him made him forget about the Cinderella girl; if she really loved him, she had to confess directly to him like Sayuki did.

And speaking of the hazel eyes girl, he was sure that she would try to seduce him and make him hers immediately from the following day and on. Something that he was going to enjoy very much.

A/N

Oya? What's this? Am I starting a fic about a new archive? Oh yes that I am! As you can see, I decided to enter in the Hensuki archive because I really liked that anime and manga. Between the various love interests of the Keiki, Sayuki Tokihara was always my favorite and I adored her and Keiki's moments together.

I didn't read the LN, but I know about how the series ended anyways. Though, since I want Sayuki to be happy with her Koshijin-sama, I decided to start this rated M fic about her and Keiki. I will follow the storyline of the anime, but with some changes as you can already see. Harem and jealous moments won't miss of course, and since this is rated M, expect it to be quite kinky fufu.

But now he knows about his dear senpai's feelings for him, what awaits Keiki from now on? To find out, get tuned and leave a review to give your opinion on this starting chapter. This black flame dragon is going to make his name known in this new archive too haha!

See ya!
