Chapter 4

During a sunny morning, Keiki was walking his usual way to school together Mao and Shouma. Though, he seemed to be in a bad mood compared to the days before, and maybe that was connected to the little bags under his eyes.

"Buddy, what's wrong? Didn't you sleep well yesterday?", asked him Shouma, patting him on the back.

"Yeah, something like that. But don't worry, I will be fine.", replied the purple haired boy, smiling. Mao was concerned about him too, but his reply managed to make her sigh in relief.

'I can't tell them that I couldn't sleep well because I had to make sure that Mizuha didn't get in my bed yesterday because she's a brocon.', he thought while hiding his annoyance with a smile. Ever since he found out that the Cinderella girl was his sister, Mizuha tried to seduce him and make him hers by trying to join him in the bath or sleep in the same bed as him.

Obviously, he was shocked that she was in love with him that much and an exhibitionist too, but as he didn't feel the same way about her because she was just a sister for him, he had to avoid all her attempts to seduce him at home.

Thankfully, she didn't try to do anything during dinner, but the fact that she wore just a swimsuit that let see most of her bare skin made Keiki blush and sigh often. It was like his life at home wasn't peaceful anymore, as he couldn't relax there with a brocon sister trying to hug him and kiss him every time.

Speaking of the girl, she was walking together him and his friends, acting normal and chatting with all of them. Though, she glanced at her brother sometimes, giving him some of those flirty smiles as he called them that he ignored. He didn't tell anybody that Mizuha was the no secret anymore girl that gave him a love letter and a pair of panties, as he didn't find it necessary.

What was necessary was to find a way for him to get a peaceful life at home at least to be able to sleep each night without worrying about a brocon trying to get in his bed. Still, something made him glad: the fact that he made Shouma meet Koharu two days ago in the canteen and that his best friend already liked the white haired girl.

In fact, Keiki managed to organize a meeting between them at the school's cafeteria, and Shouma found Koharu already cute at first glance. He was also overjoyed when Keiki said that she was their upperclassman, as that meant that she was a legal loli, the favorite type of girl of Shouma.

The beautiful voyeur was happy to spend time with the blonde and chat with him, smiling brightly when they took a photo together to celebrate their meeting. Keiki liked seeing his best buddy smiling all the time while talking with Koharu, even if there were Yuika and Mao that got jealous whenever he mentioned Sayuki.

'Now that I think about it, I could take a nap inside Sayuki's clubroom later. After all, it's always just me and her in that club.'

Since the writing club had no other members apart him, there were always only him and the cute masochist inside the room. That meant that Sayuki could spend a lot of time alone with him, hugging him and asking him if he could pet her by caressing her head.

Of course, he wasn't bothered by her evident masochistic side whenever they were alone, because it was a matter of little time before he revealed the secret side of him. A sight that he would show only to the hazel eyes girl that wanted to be his girlfriend and pet.

Anyways, once he, Mizuha and his friends reached the school, everyone went to their own classrooms. Inside Keiki's, their homeroom teacher talked about an incoming Science test that would take place in two days, so a lot of students groaned because they had to study.

The purple haired boy's grades were fine in all the subjects, so it wasn't like that studying was an issue for him. Mao and Shouma were fine as well, even if the redhead was the best of the class in Japanese literature because no one excelled like her. She also blushed whenever Keiki complimented her for that, looking away embarassed but feeling very happy.

The morning lessons went normal like the previous days, so Keiki and his group were now walking towards the canteen for lunch. On a cue, Yuika and Koharu joined them, with the little blondie latching onto Keiki's arm upon seeing him.

"How does it feel to be hugged by a cute girl, Keiki-senpai?", asked him Yuika, smiling.

Before he could answer, Sayuki appeared and hugged his other arm. "Sorry, but Keiki-kun prefers the hugs of his dear senpai.", she said smugly. Mao was frowning in annoyance at seeing them hugging the boy while Koharu was surprised by how popular he was with girls.

"Keiki-senpai likes my hugs more!", said Yuika, scowling and glaring at Sayuki.

"I don't think so. He's so sweet with me that he gave me a lap pillow one day hehe.", said the hazel eyes masochist, remembering when he visited her house.

"Say what?!", exclaimed the blondie, stopping to hug Keiki's arm and gasping like Mao did.

"Nii-San, is that true?", asked Mizuha instead, pouting when she arrived and heard Sayuki's words.

Seeing that both her and Mao were looking seriously at him while Shouma and Koharu were curious, he sighed and said that it was true. "I-I did it to thank her for caring this much about me. That's all.", he added, blushing while Sayuki hugged his arm tighter, making those soft mounds of meat hers press more against it. It was a sensation that pleased Keiki greatly of course.

Mizuha didn't like seeing her brother being lovey-dovey with the club president and was envious of Sayuki's chest. She thought that her brother liked being hugged by her just because of that. Her pouting expression remained on her face even during the way towards the cafeteria and while eating, with Yuika and Mao frowning instead.

The blondie with the green ribbon was gritting her teeth at seeing Sayuki still clinging on the boy, and knowing that he gave her a lap pillow made her way jealous. She also looked at her chest and felt the boulder with written flat chest falling on her head, making her wish to have bigger breasts at least like Mao's and Mizuha's.

Koharu was instead focused on chatting with Shouma, blushing because he didn't stop smiling at her either for a second. She also chuckles with him at seeing the various girls that were interested in Keiki, not counting Mizuha because they didn't know about her being a brocon of course.

The wanted young man simply ate his lunch while still having Sayuki cling on him, not bothered by her affection at all. He got used to it since some time, so for him it was pretty normal being hugged by her so often. Though, he sweatdropped when he noticed the jealous expressions of the other girls interested in him, making him wish again to have only a girl in love with him. He wanted just a girlfriend, not so many girls competing for his heart.

Lunch time went on like that until everyone had to go back to their classes, but before going to her classroom, Sayuki gave Keiki a little peck on the cheek, giggling. That move made him blush while the other girls except for Koharu gasped and got extremely jealous.

'Grrr, I won't let you have him,Witch-senpai!', thought Yuika, frowning angrily while the other two pouted. Their love interest didn't notice their expressions because he was still looking at the hazel girl going to her class with a grin on his face. The time to reveal the other part of him finally came.

The second period lessons were about history and math, but the young man seemed to have his mind thinking more about Sayuki than on the teachers'explanations. He liked the kiss she gave him on the cheek, and since she wanted him to be her Koshijin-sama so bad, he would show her his feelings towards her later.

After all, despite he had other 3 girls interested in him, it was only his beautiful senpai to make his heart flutter and she showed to care very much for him. Besides, if he and Sayuki became a couple, Mizuha would give up on him and he could get his peaceful life at home back; having a sister trying to cling on him and do more was quite stressful for him.

So when even the afternoon lessons ended, Keiki greeted Shouma and Mao before directing himself towards the writing clubroom, stopping before its door. Once he opened it, he found the cute masochist writing some kanji on a piece a paper. When she heard the door opening, she turned around and smiled at him.

"Welcone back, Keiki-kun. Each time you come here I get really happy.", she told him, blushing.

"Well, I'm part of this club. Besides, I like spending time with you.", he told her, closing the door with the key.

"Huh? Why did you close the door with-Kyaa~!", she tried to ask him before he walked fast towards her and got on top of her. Sayuki blushed profusely for being pinned on the floor like that by him, getting more flustered for how Keiki's eyes looked at her in a predatory way.

"W-what's wrong, Keiki-kun?", she asked him.

"Isn't it obvious? I want to make you my girlfriend and pet, Sayuki.", he took her, making her blush more and smile.

"Ehhh?! T-that means that you like me too?"

"Your care for me and the fact that you want me to be your owner made me like you romantically, triggering also my dominant and sadistic side too. I closed the door with the key in order to not get disturbed.", he told her, smirking and shocking her.

"W-what?! This is beautiful! Knowing that you are like this makes me love you-Ahn~!", she started to say before moaning when he started to grope her breasts.

"How does it feel, Sayuki~? Do you like how my hands are massaging your chest~?", asked the boy, blushing and smiling amused.

"Ahn~! Y-yeah, I like it, Koshijin-sama~.", she replied, moaning more. Liking her response, the boy decided to kiss her on the lips, making her moan again and taking her very first kiss.

'He's kissing me and playing with my breasts at the same time? This feels fantastic~.', she thought, cupping his face to kiss him back. In response, Keiki put some tongue in and started to dominate hers, enjoying how she moaned more inside his mouth.

To make her feel more pleasure, he unbuttoned her shirt and lifted her bra to touch her naked breasts. Sayuki moaned once again inside because of that move, getting more excited as result.

It was happening for real; the boy that she loved and wanted as her beloved mastMaster having his way with her, revealing also a dominant side that she adored already. Besides, being a masochist and affectionate to her kohai made her feelings for him stronger.

But suddenly, he stopped to kiss her because he brought his smirking lips to her hard nipples, giving a lick to the right one that made her moan. "Your breasts are beautiful, Sayuki~. They make me want to lick them and suck them~.", he told her, sucking the left nipple now.

"Ahn~! Lick them as you want, Koshijin-sama~! They're only yours to enjoy~! ", she said, smiling in ahegao style and hugging his head to keep him closer.

Liking what she said, Keiki proceeded to suck both nipples at turn, massaging her breasts and adoring how soft they were. Compared to the other girls he knew, Sayuki was really blessed with two beautiful mounds of meat, making Yuika's little breasts look ridiculous.

Of course, Koharu's were flatter, but Shouma was a lolicon so he was fine with it. Keiki liked only well developed tits, and Sayuki's were always his favorites to look at. Though, now that he revealed his sadistic side and the girl wanted him to be her owner, he was going to enjoy those breasts at the fullest. Also, hearing the countless moans of pleasure escaped by the girl's mouth only made him want to continue his ministrations on his chest.

'Heh, a sadistic boy and a masochistic girl…We're really two perverts made for each other.', he thought while pinching Sayuki's right nipple and loving how she moaned, begging him to not stop. If the girl had not revealed her masochism, Keiki would have just fallen for her in the future perhaps without showing to be a sadist. But things went as they went, and he could admit that he was happy for how they developed.

Also, now that he and Sayuki were a couple, Mizuha would surely stop her attempts to seduce him. While he was flattered that she was in love with him, he could see her just as his dear little sister that he grew up with. He was attracted to Sayuki ever since he joined the writing club and got more affectionate to her over the time, and as she desired to become his girlfriend and pet so bad, he wanted to love her like she did with him.

Anyways, playing with her breasts and hearing the girl's moans were making him feel more excited, with an evident bulge forming inside his pants. So he came with a funny idea.

"Sayuki, do you want to make you master happy~?", he asked her, looking into her eyes.

"Ahn~! Y-yes, tell me what you want me to do.~", she replied, looking at him with a smile and drooling.

Grinning, he got up to stand in front of her and started to unzip his pants, making Sayuki gasp and blush profusely at seeing his hard dick. "I want you to use both your mouth and your tits to pleasure me~.", he told her, patting her head.

"You're really made for me hehe. I will do my best, Koshijin-sama~.", she told him, smiling happily. Being patted on the head like she was his dog was something she adored, especially now that she was his pet for real.

So, after kneeling in front of him, she started to use her breasts to make a titjob on his dick, making it rub between them and moaning for how hot it was. She started to lick the head, tasting his precum and liking it; it was her master's taste after all.

Hearing grunt in pleasure and praise her made her very glad and relieved; she was afraid that she would make a mistake while doing a titjob for him for the first time as she desired, but thankfully she was doing really good. Besides, doing at school, inside their locked clubroom was such an exciting scenario that made her hornier and fasten the speed of her doing while also starting to suck the tip of his dick.

The young man grunted more and smirking, caressing her head and telling her that it felt fantastic. "You have to drink my load once I cum, Sayuki~.", he told her.

"I will hehe. Give it to me please~!", she said, getting hearts in the eyes. The boy reached the climax and shot his white stuff inside her mouth, making her gasp before she started to suck it and swallow it little by little. Some droplets fell on her breasts, which made her feel like he was marking as his propriety. She belonged to him just like she wished.

"Phew, you were great, Sayuki~. Having my cock being sucked by your mouth and your tits is amazing~.", he told her, caressing her head and giving her a kiss on the forehead.

"Hehe, I'm glad to know it~. Also, your cum tastes really good~.", she said, collecting the droplets on her chest with her finger to drink them. Something that Keiki liked seeing.

"Haha, you're made for me as well. I never revealed this other part of me to anyone honestly, but your fetish and your attempts to seduce me triggered it too much. Now you belong to me as my girlfriend and pet.", he told her, sitting down and hitting his lap lightly.

Smiling happily, Sayuki rested her head there and giggled while he caressed her hair, just like that time that he visited her house but with the difference that she was really his beloved pet now. That meant that other girls had any chance to make him theirs, as he loved only her.

Of course, she knew that only Yuika showed to like Keiki too while Mao just liked him as a friend in her opinion. If she were to find out about how Mizuha saw him, she would be shocked to know that she was both a brocon and an exhibitionist.

And speaking of exhibitionism, Sayuki would gladly wear just a bra and her panties if her master asked her to do it; the feeling of being half naked in front of him while he smirked and enjoyed the sight of her beautiful body would be blissful for her. Though, having her breasts sucked by his mouth and used to give him a titjob was hotter, making her already strong feelings for him go beyond.

Anyways, she kept resting her head on his lap for a while, after which she got up from it and hugged him with her face on his chest. "I feel really happy now that we're a couple, Keiki-kun. I love you.", she told him, smiling.

"I love you too, Sayuki. Since you've been very good in pleasuring me, we're going on a date this week. Unless you want me to put a collar on your neck and taking you for a walk at night~.", he said, teasing her and making her blush profusely.

"A date?! And you would take me for a walk like I were a dog?! Oh, Keiki-kun!", she exclaimed, jumping him to start kissing him lovingly. He kissed her back of course, as her lips weren't covered with his cum anymore since she drank it all.

The moans that she released because of his tongue playing with hers was music for ears, so he hugged her behind her waist to keep her closer like she was doing by cupping his face. If someone entered in the room, they would be shocked to see them making out like that at school. But obviously, Keiki wouldn't hesitate to kiss Sayuki aggressively in public too; she was his girlfriend, so he would show that she belonged to him alone.

The girl would kiss him too if she noticed another woman trying to take her Koshijin away from her, as dogs could get jealous of those giving affections to their owners. She would also mark her territory by licking his face or his lips if they were alone, even if kissing him like at the moment was more romantic.

The two of them continued to make out for a while, before reluctantly pulling their lips apart and gazing into each other's eyes with nothing but love. "Keiki-kun, I want to celebrate our new relationship. Give me some minutes.", she said, getting off him and sitting at the table she used for writing kanji. The young man raised an eyebrow and observed her, liking how she smiled while writing something on a piece of paper.

Once she was done after some minutes, she showed what she wrote to him: their names in kanji with various hearts around them. "I will attach this to the wall to indicate that this club is the place where we became lovers hehe.", she told him, smiling and blushing.

"Heh, I like it, Sayuki. You're really the best.", he told her, patting her head and making her giggle in bliss. She would never get tired of his headpats, even if she would like being petted on her belly too. And she had the perfect accessories for something like that, which she would use maybe when she would go to visit his house.

Now that he was her boyfriend and he had already visited her house, it was fair that she would go to his as well, looking forward to enter in his bedroom and do naughty things with him. She was aware that Mizuha was in the house too, but the beautiful masochist could just go to visit him when he was alone at home.

Giving him a titsjob was just the beginning, as she looked forward to do other ecchi things with him. And since he was a sadist, she was sure that he had other stuff in mind too that would include her being totally dominated by him. She was his lovely girlfriend and pet, so he could have his way with her how he wanted and she would be glad for it. Their new relationship had just started.

A/N

And the 4th chapter is here! As you can read, Keiki revealed that other side of him to Sayuki that he kept hidden for a long time, arriving to kiss her and do lewd stuff with her while dominating her fufu.

Her attempts to seduce him and the affection that Keiki developed for her brought him to confess to her and making her his girlfriend to Sayuki's joy. Though, the other girls may not give up on him immediately even if they find out that he's already taken, as Mizuha, Mao and Yuika will surely try to make other moves on him. Especially the first that is already trying to get in his bed at home. His lolicon friend is fine with Koharu being the only one that loves him, so we can say that Shouma is luckier than Keiki maybe haha. Stay tuned to see what will happen next.

See ya!
