Chapter 10

During the end of a normal school day, while Fuutarou was practicing swimming with the club, his stepsisters and Haruka were there to look at him and admire his hot body, which was more handsome after he swam.

It passed some days since the young man had took Miku and Nino's virginities, and after that, the two girls were even more eager to kiss him on the lips even before their parents and Raiha's eyes. Their sisters were surprised by their behavior, asking themselves what changed them.

Obviously, the self proclaimed wife and the headphones girl didn't start to kiss him at school too, as he had made it clear to his stepsisters to refrain from doing it there in order to avoid annoying rumours. Haruka also noticed that he wasn't flustered with her like he was with his sisters, which had made her pout in jealousy often.

Anyways, while Fuutarou was swimming, Nino didn't stop to look at him either a second, licking her lips and blushing; since she had sex with her beloved Fuu-niichan, she wanted to do it again with him and enjoy his huge dick inside her pussy. It was like she got addicted to be fucked by him, but that just was because she loved him deeply.

She always considered him her hero since the day she met him when he saved her and her sisters, falling in love with him everyday after he became her family. In fact, she always wanted to play with him by being a princess that would be saved from him, her dear prince, before starting to kiss him lovingly.

She never cared about other boys because she had eyes only for her big brother, and after he took her virginity, her feelings for him were much stronger. Of course, Miku's love for Fuutarou was much bigger too, as she always sat on his lap while playing games together on the couch and would sleep more often in his room at night.

The other quints understood, by looking at their actions, that they got closer to Fuutarou somehow. And Yotsuba, wanting to be closer to him too, decided that she would find out what made him get closer to her sisters in order to make him more affectionate to her as well.

'I was Nii-sama's first kiss, so I want to be lovey-dovey with him too!', she thought, determined to be kissed on the lips by him often like it happened to Nino and Miku. Obviously, Ichika and Itsuki felt the same way because if they were going to share their big brother, it would be fair that each quint got the same amount of love from him.


Later, once he finished his club activities, the ace swimmer was taking a shower in the lockers room, with his teammates gasping at seeing his beast. "Dude, what do you have between your legs?! It's huge!", said one of them in shock.

"I-I believe it you attract girls so much!", said another, making Fuutarou sweatdrop and laugh awkwardly.

'I h-have already my stepsisters that love me too much. I know that Haruka likes me too, but I will have to be honest with her.', he thought, with the faces of his 5 sisters appearing in his mind with smiles. Since he accepted his feelings for them and even made love to 2 of them, he knew that he couldn't let Haruka continue to love him.

Even if he was happy that she liked him since childhood, the quints' feelings for him and their countless affections brought him to love them more than as simple siblings. If not, he wouldn't have had sex with Nino and Miku, as he wanted to make love only to a woman he loved.

And it seemed that it was 5 girls that he loved deeply from the bottom of his heart, and since he wanted to show affections to them fairly, he wanted to have sex with the other 3 too. And perhaps, that could happen at night or earlier at home, since he had the feeling about it.

After taking a shower and greeting his club, the young man was swarmed by a lot of fangirls that asked him for his autograph or attempted to cling on him until his butterfly ribbons sisters arrived and hugged him.

"Fuu-niichan, let's go home. Papa and Mama will be worried if we're late.", she told him, smiling.

"Yeah, let's go, Nino.", he told her, smiling back at her. The girl also launched a glare to the fangirls, scaring them.

'Go find yourselves other boys, homewreckers! Fuu-niichan is only mine!', was the message she conveyed through her glare, acting possessive of her brother as usual. On a cue, her sisters appeared too and latched onto Fuutarou as well, not letting Haruka get close to him at all.

Though, the blue haired girl tried to have his attention too during the way by talking with him, making Nino scowl at her while the others frowned or pouted. They didn't hate her, but they wished she stopped being interested in their brother; it was obvious he loved only them, so she would do a wise decision by falling for someone else.

The way to home was full of chatting and giggles from the quints and Haruka at hearing Fuutarou's jokes, with the glasses girl greeting everyone before entering in her house. All the quints greeted her back, except for Nino that scoffed and thought instead of pressing her breasts on Fuutarou's arm, smiling and blushing.

To her joy, he was flustered and even patted her head, making her smile more; she was truly happy that they were much closer, and skinshipping with him was fantastic for her. Her sisters clung on him as well, and since they were out of school, they started their famous kissing storm on his face.

"G-Girls, calm down.", he told them, blushing while getting thousands of kiss marks.

"Fufu, we're just showing affection for you, Fuu-nii. Don't be shy."

"Yeah, after all, we love Nii-sama more than anything in this world!", exclaimed the bunny ribbon quint, monopolizing his face with her kisses.

"Hey! No fair! Let me kiss Fuu-niisan too mouu!", complained a pouting Itsuki, starting a contest with Yotsuba for getting to kiss Fuutarou's face.

Nino, Ichika and Miku didn't want to be ignored, so they joined in filling the boy's face of kiss marks all the way to their house.

Upon stepping inside, Raiha appeared and greeted everyone with hugs, giggling at seeing her brother's face covered with countless kiss marks as usual. "Hehe, you really love getting kissed by the big sisters, Onii-chan. Did Nino-nee kiss you on the lips too?", teased him the little girl.

"Ah! I was forgetting to do it. Come here, Fuu-niichan~.", said the social butterfly, cupping his face and planting her lips on his.

Blushing, the young man's eyes widened at seeing Isanari taking a photo of them with his camera, with a giggling Shizuku by his side. "Haha, we finally got a photo of you showing love to one of your future wives.", said the blonde man, chuckling.

"Papa, I want a copy of that! I want to put in a frame in my room."

"Sure, Nino-chan. Oh, you 4 want to kiss him and have a photo as well?", he asked to the others, getting fast nods and smiles in return. Fuutarou sweatdropped before receiving a kiss on the lips from each one of the other quints, reciprocating them anyways like he did with Nino.

His parents and Raiha smiled at seeing him returning his stepsisters' affections, with Shizuku giving a photo to each quint of their kisses with their brother. Said brother went then towards his room because he wanted to study a little, but Yotsuba said that she wanted to study with him because she needed help with English.

'While I will be alone with Nii-sama, I can find out what made him more affectionate to Nino and Miku. So I can get closer to him as well hehe.', she thought, latching on her big brother's arm and giggling while climbing the stairs. Her sisters didn't pout at that because they had accepted to share him after all, even if Nino still preferred to monopolize him. She was his self proclaimed wife, after all.


Once they got to his room, Yotsuba and Fuutarou sat down on his bed and took their notebooks to study, with him helping her with some English translations and patting her head while praising her. "Hehe, I really love you, Fuutarou-niisama. Each time you give me affection, I'm so happy.", she told him, hugging him.

"Well, you're my dear sister. Also, I l-love you very much as well.", he told her, suddenly holding her face and kissing her.

Stunned and flushed, she happily kissed him back, moaning when she felt his tongue entering in her mouth and playing with hers. 'N-Nii-sama~…', she thought, loving how his tongue dominated hers. She also gasped in his mouth when one of his hands groped her chest, massaging her left breast under her school uniform's shirt.

'T-this is what made him closer to Nino and Miku~? Ahn~, it feels great~!', she thought, moaning louder inside his mouth when also her right breast got groped.

'She has them big like her sisters. I want to see them~.', he thought instead, breaking off the kiss to lift her shirt and her bra to see her big mounds of meat.

Beyond flustered, Yotsuba didn't try to hide her breasts at all and started to look at him with hearts like eyes. "N-Nii-sama~, do what you want to me~. I-I want your love~!", she told him, inviting him with her arms stretched.

"Don't worry, I will give you all the love I have~. Let me do something first~.", he said, kissing her on the forehead before getting up to turn off the light. He also took off his clothes as long his underwear, remaining naked with his beast of a cock in full vision for Yotsuba that started to drool while a wet spot formed on her panties.

Turning back to her, the young man didn't hesitate to start sucking her tits, making her moan loudly by licking her nipples. Yotsuba made an ahegao face and hugged his head to keep him close, moaning more when she felt him touching inside her panties.

"T-Take me now, Nii-sama~! I-I want to be one with you~!", she said, smiling and drooling, with her heart like pupils looking at him.

Grinning, he stopped sucking and licking her now covered in saliva and hickeys tits to take off her pants and bringing his dick close to her pussy, teasing her clitoris with its head. He then inserted it for real inside, making her gasp and moan loudly while she felt her hymen breaking.

"Aaaaah~, Nii-sama is inside me~! I-I'm one with you finally~!", she exclaimed, succumbing to the pleasure.

"I will move slowly, Yotsuba~. I will make you feel very good~.", he told her, starting to move his hips to thrust her. The long haired bunny ribbon quint moaned more at that, doing it also inside his mouth when he made out with her. As expected, Yotsuba's pussy was just like her sisters' and so they were her breasts while he massaged them for good.

Since he took the virginities of two of his sisters already, he wanted to give his love to Ichika, Yotsuba and Itsuki as well. So, he was going to make his fourth stepsister feel like in Heaven. But she felt already like that, as she had an ahegao smile and continued to tell him how much she loved him, which made him only accelerate his thrusts and reach deep inside her womb.

He also started to fuck her in doggy style, clashing his hips against her butt cheeks while groping her tits and kissing her neck. Yotsuba didn't stop to moan either for a second and her pussy juices continued to drip from her cunt, loving how her brother's dick went in and out of her.

"Ahn~! Ahn~! Ahn~! I-I love you, Nii-sama~! I love you and your big cock, Nii-sama~! Aaaah~!", she exclaimed, reaching her climax and releasing a big amount of pussy juices. Fuutarou's orgasm arrived in the same moment, but this time, he shot all of his semen inside her pussy and womb to give her a creampie that she adored.

'After doing it raw already, I don't think it's a problem if I cum inside of her. She seems to love it too~.', he thought, smiling at seeing her lewd smile and panting after cumming and filled with his semen.

"N-Nii-sama~...I-I love you so much~.", she mumbled, still having hearts in her eyes.

"I guess I'm lucky to have such a beautiful and affectionate sister~. You deserve a reward~.", he told her before laying down on the bed and pointing at his cock.

"Y-yes~, I want more of your dick~.", she said, getting on top of him with her pussy above his covered in semen and pussy juices dick. She then impaled herself with it and moaned while starting to move her hips up and down.

Fuutarou groped her tits and loved seeing her moving like that on top of him; her long red hair moved around and he could admire her happy ahegao smile before she leaned down to kiss him. Since each room was soundproof and his was closed with the key, he didn't have to worry about someone suddenly entering in the room. Plus, as it was still afternoon, he didn't have to worry coming down for dinner immediately together with his sisters. Which meant that he could give her another good dose of love.

The two of them changed position again for a reverse cowgirl one and then one where he had her against her the wall to thrust up and down inside her full of semen cunt. Yotsuba couldn't help but moan more and more while being fucked by him in different positions, continuing to release juices from her pussy.

'N-Nii-sama is too fantastic~! Ahn~! I love having sex with him~!', she thought, making out with him and enjoying his tongue. She was beyond happy that she and her sisters were the only ones he would make love to, which only made her warmer and wetter for him.

It didn't take more than some seconds before she came again, with her juices and some droplets of Fuutarou's previous cumshots falling on the floor. Panting and smiling, she leaned her head on his shoulder. "W-we're now closer to each other, N-Nii-sama~. I-I feel like the happiest girl of the world~.", she told him, not stopping to hug him.

Smiling, he carried her in princess style and laid down on his bed with her on his chest to rest, kissing her cheek and caressing her hair. "I wanted to show you how much I hold you dear, Yotsuba~. You and your sisters are the only ones with a special place in my heart~."

Happy, she hugged him tighter and felt asleep on his chest, totally exhausted after cumming and receiving creampies so many times. The young man chuckled and caressed her head, admiring her happy expression. Since he met them in childhood, he could recognize the face of each one of his sisters easily despite they were identical to each other.

And following what Rena told him once before she died because of her illness, only people with love could distinguish his stepsisters. Maybe he liked them already when he first met them, and he tried to not give in his feelings because he was afraid of what other people would say.

Though, his parents supporting a marriage between him and the quints and their big love for him broke that barrier that impeded his real feelings to be expressed. So now, he was going to show to each quint how important she was for him, and after Yotsuba, it would be Ichika and Itsuki's turn.

But there was a problem he had to resolve: what to do with Haruka's feelings. While he was glad that she loved him, he didn't feel the same way about her because only the quints were special to him and didn't want to betray them. At all.

If there was something he despised to death, betrayal was the main one. Be it in love or friendship, he absolutely detested any form of betrayal and would look at cheaters with disgust. So there was no way in hell he would become like those people, which was why he had to tell Haruka straight about his real feelings.

If he continued to let her love him, her feelings could get stronger and it would be more painful for her when he would reject her. So, even if he knew he would hurt her feelings, he had to talk with her soon about it. He just hoped that she would remain his friend, as he didn't want her to think that he hated her.

As if she perceived his worry, Yotsuba hugged him tighter to comfort him, causing him to smile. 'Your kindness is what I love the most about you, Yotsuba.', he thought, kissing her on the forehead and making her smile in her sleep.


He checked the hour to see that it was 5 pm, so he gently moved her arms and got up from his bed to wear some pants. Covering the beautiful body of his girlfriend, he put a blanket upon her and kissed her on the forehead. "Rest well, Yotsuba~. I love you~.", he told her, liking how she mumbled a "I love you too" in her sleep.

After that, he took some new clothes from his room and went towards the bathroom to take a shower. Thankfully, he didn't bump into anyone during the way, so he didn't have to explain his sweat and why he was shirtless. Even if he had the guess that, if one of his stepsisters saw him, she would blush and nosebleed.

Anyways, once he stepped inside the bathroom, he got in the shower and started to let the water run on his sexy body. Being an ace swimmer required strength and resistance, so the young man never stopped pushing himself beyond his limits to reach the level he was at now.

But it was because of that and his brave character in defending the others from bullies that he was the most popular boy in his school, as no one could surpass him in attracting the eyes and the interest of various girls. Nonetheless, he had eyes only for his sisters, so he didn't want to reciprocate the interest of his countless fangirls; his heart belonged already to 5 girls.

Following his shower, he wore a sleeveless black t-shirt and grey pants, with the sharp tooth necklace that Yotsuba gifted him in full sight. Speaking of sharks, he got a great white shark tattoo on his right shoulder, as he had managed to convince Shizuku to let him get tattooed with Isanari's help. And having a tattoo just increased the sex appeal he already had.

The young man got out of the bathroom then to go downstairs, finding Itsuki and Miku watching a movie on the TV. "Oh, Fuu-niisan! Come here! This movie is very interesting.", told him a happy Itsuki upon seeing and patting the free spot next to her.

"N-No, sit next to me, Fuutarou-nii.", said a pouting Miku instead.

Sighing and smiling, he sat down between in the end, hugging them from their shoulders to bring them close to them. Flushed and happy, they hugged him and started to watch the movie with him, which happened to be a funny one of Woody Allen.

'Fuu-niisan/Fuutarou-nii is so warm and huggable.', the two quints, smiling brightly while giving him affection. But another quint was observing them from the kitchen, so she didn't waste time in appearing with a pout on her face.

"I want to cling on my big brother too!", exclaimed Nino, sitting on his lap and leaning her head on his chest.

"Nino, Fuu-niisan is our big brother, not just yours."

"Hmph, but Fuu-niichan loves my cooking more than anything else.", retorted the butterfly ribbons girl, wrapping her arms around the boy.

"Girls, don't fight. You know I love each one of you equally.", he said, sweatdropping.

The 3 girls blushed and giggled at his words, starting to kiss his face repeatedly. 'I always end up with countless kiss marks in the end.', he thought, chuckling because their kisses tickled him.

In the same moment, Yotsuba appeared and saw her sisters giving him various kisses. Smiling, she approached them and joined in kissing her Nii-sama.

'It looks like she rested enough after I had sex with her. Maybe I overdid it when I came inside her more than twice, but when it comes to these girls, I have troubles in controlling myself. As long as no one knows about it at school, I can protect my sisters easily.',he thought, hugging all the quints, including Ichika that started to kiss him.

Protecting them was his duty as they'd big brother and love, so he would make sure that anyone didn't badmouth one of them at Asahiyama. The quints were his family and the girls he loved very much, so anyone that hurt them would know the terror of the Furious Shark.

Considering how he liked such animal, he wasn't anymore a tiger that needed to be provoked before getting angry. He was like a shark ready to make who made the quints cry pay dearly. Be it a boy or a girl, it didn't matter. No one had to harm his family. At all.

Though, he has the problem regarding Haruka's feelings for him to resolve, as he can't let her getting heartbroken painfully by waiting to tell her about his real feelings.

Since he let his love for the quints come out, he's now even more protective of them and wouldn't hesitate to throw hands against those that dared to make them cry. They're the girl he holds dear in his heart after all. What's going to happen next? Will Fuutarou manage to keep his friendship with Haruka? Who will be the next quint to experience Fuutarou's big love for her? Stay tuned to find out.
