Chapter 7

Inside a public bus, Sayuki and Keiki were sitting next each other while she rested her head on his lap. The summer had finally arrived, so the two of them were directed to the beach for their awaited date there.

Of course, the sadistic purple haired boy had hot ideas in mind for his private time with the hazel eyes girl, who was giggling and enjoying his lap pillow along his headpats. Dogs adored being clingy with their owners, so it was normal that she, as his beloved pet and girlfriend, acted like that.

"You seem really happy, Sayuki."

"Of course I am, Keiki-kun. Going to the beach with my boyfriend for the first time gives me immense joy hehe.", was her happy reply.

"And I can't wait to see you in your swimsuit~.", he told her, kissing her forehead and making her blush. Since they weren't alone in the bus, some old women blushed before his audacity and found the couple very cute.

In fact, she and her Goshujin got much closer after the numerous times they had sex and he brought her to walk at night with a leash and a collar. Yuika didn't try to butt in their relationship anymore after he teased her sadistically and Mao didn't show her jealousy like before, even if he suspected that she still drew doujinshi where he fucked her.

Also Shouma and Koharu seemed way more affectionate to each other, and to Keiki's surprise, they made love inside the blonde's house. Of course, Shouma's sisters didn't know anything yet about it or having a girlfriend because the risk of them going brocon mode was too high.

So the last days of school before summer had proceeded well for everyone, and now that they had lots of free time, the young man and his pet could finally enjoy a date at the beach. Since they would stay there all the day, Sayuki prepared the lunch and the dinner for both of them while he took the beach umbrella, the sun cream and everything else.

'Putting the cream on your body will be fun~.', he thought, looking at his girlfriend with a grin. He looked forward to hear her moan because of his touch on her beautiful body.

She noticed that grin and smiled happily, knowing what it meant; it was like their minds could read each other, which fueled further their strong feelings for one another. It wasn't a case that she cupped his face, bringing her lips to his for a nice kiss that shocked all the other passengers.

After twenty minutes from when they took the bus, the couple arrived to the beach in the end, with Sayuki's eyes shining at the sight. "Hehe, we're here finally. Let's go, Keiki-kun!", she told him enthusiastically.

"Heh, I like seeing you in high spirits.", he said instead, nodding and walking alongside her. As expected, the place was crowded already despite it was only morning, with various people taking the sun and children playing and swimming in the water.

So the two highschoolers didn't waste time in walking towards there, searching for a free spot to plant the beach umbrella. Out of luck or not, they found it close to the water, so the purple eyes boy planted it in the sand, opened it and took out two towels from the beg.

Feeling the bright hot light of the sun, he took off his t-shirt instantly, making his pet blush. "Oya, why are you blushing? You saw me shirtless a lot of times~.", he said, smiling.

"It's just that you look always so handsome hehe. Also, what do you think of this?"

Following that question, she took off her dress to reveal a two pieces blue swimsuit that emphasized her curves and her big breasts. Blushing, the boy continued to smile and caressed her head, making her giggle.

"You look so damn beautiful of course. I knew that it was perfect for you when we bought it together.", he told her, making her skip a heartbeat. She also hugged him and snuggled on his chest, getting reciprocated too.

'Aww, Goshujin-sama's praises always fill me of joy. I love you so much.', she thought, blushing more because he kissed her cheek under the surprised eyes of other people. Couples being that sweet in public could be pretty uncommon sometimes, as it seemed.

Afterwards, she laid on her towel and he didn't waste a second to put the sun cream on her body, touching her sensually and causing her to moan as he wanted. With his hands, he massaged her back, her thighs and her legs for good, adoring the sound of pleasure escaped from her mouth.

"Someone is pretty sensitive here, huh~?"

"K-Keiki-kun's touching my body feels so good~. I will put the cream on you now."

The hazel eyes girl blushed and smiled more while touching his chest along his arms and his legs. Even if her owner didn't have a muscular body, he was always so gorgeous to her eyes and cupped his face for another lovely kiss.

"Alright, now that we're ready, let's go to swim!"

Nodding happily to him, she followed him inside the water and they started to play together, splashing each other or seeing what lied underwater between various types of fishes. The sea water wasn't too cold fortunately, they hadn't any chill while stepping inside. The young man also dived in sometimes and hugged Sayuki from behind, kissing her cheek again.

"Are you having fun?", he asked her with a smile.

"Of course I am. Since you're my first boyfriend, I'm overjoyed to be here with you. It also makes me cherish more the day you joined my club.", she replied, snuggling her face on his neck.

"To be honest with you, the reason I joined there wasn't only to help you, but also the fact that I admired you whenever you wrote something so elegantly. It made me want to know you more.", he told her, surprising her and making her blush.

"R-really? Aww, you make me so happy, Keiki-kun."

After saying that, she joined her lips with his once again and he put some tongue into it to hear her moans. What he told her was the pure truth because he was truly fascinated by how beautiful she looked when he saw her writing for the first time.

He was even glad that he was the only member to be part of her club, as it became pretty much the love nest for all their romantic moments and sex sessions. They never got found out by some teacher thankfully and besides, when her parents weren't at home, her boyfriend fucked her for good and stayed for the night too.

Speaking of fucking, seeing her with her swimsuit and her skin wet after swimming kinda excited him, so he whispered in her ear, "Hey Sayuki, do you see those rocks there? Let's hide between them~."

Looking at where he pointed, her face got redder and she smiled back at him. "Yes, Goshujin-sama~."

So the two of them swam towards those rocks, which were far away from other people, and hid there before they hugged each other and started to make out passionately. While she hugged his neck, his hands went to touch her ass and squeezed it, adoring how soft it was.

His penis was getting harder inside his swimsuit, touching her private part and making her giggle in her mind. "Ahn~! G-goshujin-sama~…", she said, squirming because he put a finger in her pussy from behind.

"Oho, you're already somewhat wet here~. Is it the sea water or are you excited~?"

"I'm excited of course~. I get like this each time you want to make love to me, ahn~!", she replied, getting heart shaped pupils.

"Haha, my pet is so adorable~. If you're so ready, let's forget about preliminaries~."

True to his words, he made her lean on rock wall, pulled down the second piece of her swimsuit and lifted one of her legs before entering inside her cunt with his junk. Sayuki released a loud moan at that, smiling more though and loving how he began to thrust.

'Her pussy is so easy to thrust after swimming~. It feels great~.', he thought, giving a smack to her butt that made her yelp and moan more.

"Ahn~! Ahn~! Spank me more, Goshujin-sa-Ahn~!"

"What a horny pet you are~. Getting more excited because I spanked you just makes me want to fuck you more~!", he told her, accelerating the speed and increasing her squirming.

Sayuki was unable to contain her moans, as his thrusts went deep inside her womb and she continued to smile and drool in ahegao style. The salacious smile on his face made her wetter and happier that he was her boyfriend, because he was truly made for her in her opinion.

While he could be sweet and caring, he also had that sadistic side of him that showed whenever they had sex, not hesitating to hit her butt or to tie her up in different ways to his enjoyment. A masochist like her could just get always excited at the idea of being ravished by him and she saw it as a proof of his intense love for her.

'Ahn~! Ahn~! Only I am in your heart~! My rivals don't have any chance~!', she thought, kissing him and moaning more after another butt smack. She wasn't aware that his stepsister had feelings for him, but she knew about the other girls because he told her about Mao's fetish.

She could understand why they fell for him: her boyfriend was always ready to help the others and cared about his family and his friends, as seen when he helped Koharu to become Shouma's girlfriend and that time he tried to comfort his sister after rejecting her. In fact, despite he was sadistic, he cared a lot for Sayuki's feelings, and she could see it through all his actions to make her happy.

And since she was his dear pet, it was her duty to make him happy as well and licked his face like a dog while he ravished her. "Good girl~. Moan more for me~!"

"Woof, ahn~! Ahn~! I-I'm cumming~!", she exclaimed after barking, releasing more pussy juices that fell down on the ground.

That didn't stop her master from thrusting up and down more, which caused her to continue squirming. "I haven't come yet, so I won't stop~.", he told her, grinning.

"Ahn~! Ahn~! Do what you desire with me, my owner~! Everything of me belongs to yo-Mmh~!"

Liking her words, he put his lips on hers and lifted her other leg too, so she wrapped them around his back while her arms hugged his neck. In that way he could reach deeper in her cunt, loving how easy to penetrate it was after her climax. Despite knowing she was pretty sensitive after that, he looked forward to make her climax again but together with him.

Since his hands were constantly on her ass, one of his fingers went inside her other hole, increasing the number of her moans. She told him that everything of her belonged to him, so she was overjoyed that he was having fun with her butthole too; it made her love him more.

'Ahh, I will never get tired of fucking you, Sayuki~. You're always so beautiful when you moan~.'

'I'm glad to know it, Goshujin-sama~!'

They literally read their minds because he accelerated another time while she continued to kiss lovingly, being a hopeless prey of his sexual desire for her. He wished to have a vibrator or a tail plug to put it in her ass at the moment, but his finger seemed to be enough because he could feel that the hole tightened around it, as if it loved it.

Even her pussy was tighter and seemed to not let go of his dick, which fueled the hots for her and he spanked her again to her happiness. Besides, seeing her naked breasts moving up and down while he ravished her was a nice sight and he brought his mouth to her left one to suck it hungrily.

All that much pleasure all over her body was so great for the girl that she climaxed another time, followed by him that shot his semen all the way to her womb. "Ahhhh~! M-my juices and your stuff are mixing together again~!", she happily exclaimed.

"This is the proof of our love~. The only girl that deserves to be my pet and my girlfriend is you~.", he told her, kissing her briefly and making her giggle and woof.

After that, he took his dick out of her pussy, from which some of his semen was dripping down. Not wanting to lose it, she collected it with a finger and swallowed it, adoring how it tasted. Seeing that there was still some on his dick, she smiled and knelt down to suck it and clean it up for him as a good pet should do.

"Yes, that's good, Sayuki~. You get better at sucking every time~."

"Thank you so much, my owner~. Your praises fill my heart of joy~.", she told him, sucking his shaft happily to not waste any drop of his semen. After giving him various blowjobs, she was completely in love with that taste because it was her beloved's one and only she could enjoy as he told her.

The way her tongue licked the head while the length went down for her throat was truly amazing for him, who gave her headpats and called her a good girl to her happiness. So she finished to clean his dick up and he sat down next to her, giving her another lap pillow that she rightfully enjoyed.

"Your pussy and your body were fantastic as always, Sayuki. I think that your tits got bigger too."

"Hearing that makes me so happy hehe. I do my best to be sexy for you, Keiki-kun~.", she said, licking his hand like a dog.

"Is that so? Then, here."

He used his other hand to scratch her tummy, which made her blush again but smile too. The more he treated as his pet, the happier she became while her feelings for him grew stronger.

Of course, she didn't know that her boyfriend used to play with a real dog as a child back in his childhood, which belonged to his and Mizuha's grandfather. In fact, that dog was really affectionate to him and she always licked his face, just like Sayuki just did again for being so sweet with her.

Though, the sudden sounds of their stomachs interrupted their lovely moment, causing them to laugh before agreeing to go back ot their beach umbrella. Thankfully, no one stole their bags or something else, so the beautiful masochist took out the lunch boxes she made for both of them.

"If you cook so well, you're totally perfect to become a wife. This is delicious!", were his words after eating a piece of roasted meat delightfully.

"Fufu, becoming your wife would make me overjoyed. I love you, Keiki-kun.", she told him, leaning her head on his shoulder and smiling.

He blushed like her and kissed her forehead, adoring how they could so many sweet moments together. As his wish was to have a girlfriend during high school, he was glad that that person happened to be his dear senpai; never once she stopped caring for him and combining her masochism with his sadism, they were literally made for each other.

Maybe he could have fallen for Yuika instead, since she and he got very close because of his insistence to make friends with her, but after finding out her perverted side, there was no way he would like her. He knew Mao from middle school instead and she had a better chance, but Sayuki was the one that he fell in love with in the end.

'You're going to get graduated before me, though that doesn't mean I will leave you. You're only mine.', he thought, smiling and looking at her blissful face while still eating.

"Keiki-kun, you look at me so much."

"A good man should always look at the woman he loves. After all, there's only you in my heart.", he told her, making her heart beat faster while her pupils shined. She also giggled when he caressed her face, getting tempted to lick it but thinking twice because they were in public.

They continued then to have lunch like that and she arrived to feed him sweetly, wanting to spoil him as a good senpai had to. Considering that her food was literally delicious, he couldn't get tired of eating it at all and he got more convinced that she was really perfect to marry. Mizuha's cooking was good too, but she was his sister for him.

He understood that she was deeply in love with him since they were younger, still his heart raced only for the cute girl in front of him and didn't want to betray her. He despised those that betrayed other people's trust, so there was no way he would do that to her and his friends.

It wasn't a case that he did his best to help Koharu to get together with Shouma, because he understood her feelings and wanted his best friend to be happy. Since the first was a voyeur for the blonde and the second a lolicon into legal ones, they were a perfect match and he liked seeing them so happy when they were together.

Anyways, once both of them were done with eating, he decided to take a nap on his towel, getting joined by her who clung onto his arm. "I was right, your breasts got really bigger."

"Fufu, but you love big tits, Keiki-kun. You play with them so often~."

"I love every single thing about you and I don't care about other women~.", he told her, hugging her closer and kissing her forehead. Smiling blissfully, she snuggled into his chest under the surprised looks of everyone else, with some kids blushing before so much affection especially.

Usually they would say something like "Yuck!" in front of a kiss, but since boys or girls were used to have their first crushes during childhood too, they would get flustered instead. Certainly, someone so straightforward with his feelings like the purple headed boy would surprise everyone, unless they knew about his perverted side.

Though, he was always a kind person that held dear all those he was affectionate to, especially the beauty in his arms. He didn't care if he was too clingy perhaps with her, because a guy that didn't give even a bit of affection to his girlfriend was heartless in his opinion.

Besides, having her so close to him made him smile in his sleep, enjoying the atmosphere created by the lovely moment, the breeze and the place they were at. Each one of their senses was relaxed and Sayuki smiled brightly at hearing the heartbeats of her master; they were such a beautiful sound.

'I want to continue to have these moments with you, my owner. You accepted me as I am and you give me so much love every single day, so I want us to stay together forever hehe.', she thought in her sleep and blushing. The idea that they got together after he received that love letter from another girl was incredible, but she was thankful to that person anyways.

She wasn't ready to confess her love to him because she feared that he would hate her perverted side, still she didn't want to lose him to another woman. Besides, discovering about his sadism filled of an immense happiness, especially when he reciprocated her feelings and made her his pet.

Just like he didn't care at all about other women, she was the same because it existed only him for her. No one deserved to be her owner and her boyfriend, as she had eyes exclusively for her gorgeous sadistic kouhai that loved ravishing her like there was no tomorrow.

In fact, they looked forward to have sex later in the evening and going for a dog walk again. That would make their first date on the beach totally unforgettable and more beautiful.
