This is a story based on the dj manga. However, Haru is a girl and there will be a couple of OCs. Characters might be OC as well. Disclaimer: I own nothing. By the way, just to be clear, in this story, they have the bodies of humans, but have cat ears and a tail. They are not hybrids. Also, I had help from this from an awesome person called KarouUchiha, credit also goes to her.

Characters:

Rin- A male cat raised by Toka ever since he was young. He can be a sore loser and often tries to compete with Haru. He is secretly in love with her, yet denies it and acts like a tsundere towards her. He often complains, but is truly a kind person. He is sometimes annoyed by Kokoro, but cares for her. He is very conscious about the fact that he used to a crybaby, and still is a little bit, and will go on a rampage every time someone talks about it.

Haruka- A black, female cat who was taken in by Toka. Her nickname is Haru. She is tomboyish, quiet, and has sharp intuition. Her behavior is bit hard to read, but from an owner's point view, she is just carefree but obedient. She loves baths and is crazy for anything that has to do with water. She favorite food is mackerel. She is also fond and protective of Kokoro. It is hinted that she is in love with Rin.

Kokoro- A young kitten who is Haru's cousin and was taken into Toka's care with her. Compered to her cousin, she is more active, talkative, and outgoing. She loves water like her cousin. Mackerel is her favorite food, as well. She is also fond of Rin, calling him 'Onii-chan', and sometimes teases him about his feelings for Haru, who she calls 'Onee-chan'. She is also quite smart and precocious for her age.

Toka Todo- A university student and the cats owner. She is very motherly and thoughtful, but is at times strict and uptight as any other owner. She has a hobby where she tries out new pet articles for cats to embarrass Rin.

Sexy Tail: First Half

A night in April... That is a night when the air is filled with passion. Under the moonlight, all nearby stray cats gather together on top of the roofs of houses. A party of grand courting then begins. However, if males are kept locked inside the house during this time, it can get very noisy as they meow all throughout the night. And thus, that night, the cat's owner didn't get any sleep at all.

The next day

"Hey, Toka, how come I didn't get any canned food today?" Rin asked.

"We ran out of it all." the light brown haired young woman replied, not looking up at him as she twirled a spoon in her cup of coffee.

"But Haru and Kokoro got their share, and quite a lot, too." the male cat retorted, gesturing towards the two cousins, who were just watching the conversation that was going on as they ate.

"Haru-chan and Kokoro-chan are always good girls, so they got the leftovers." Toka told him as she pulled the spoon out of her drink. "Good children don't make loud noises all night long." she remarked as she finally looked up, showing her tired eyes and the bags that were under them through her glasses.

"Ugh!" Rin flinched, knowing what she was taking about.

"So it's only logical that you don't get any, don't you think?" the young woman questioned.

"It's not like I do it because I want to..." the redheaded cat started to say as he turned his head, rubbing the back of his neck. "It's mainly because of my instincts that I'm not able to hold back. Besides, it's only until late at night."

"I guess it can't be helped." Toka said. "I must get you castrated."

Rin's whole body froze as he repeated what his owner just said in his mind, his ears and tail going stiff. "Wait just a minute here!" he shouted as he stood up from his seat. "Yesterday was the only time I made any noise! You can't just have me castrated straight away because of that!"

"Even though it was the first time, it was horrible." the light brown haired woman remarked. "If it happens again, no doubt that the neighbors will complain. Besides..." she gave the male cat with a serious look. "I can't risk having you and Haru-chan mating and having little black and red kittens running around the place."

"As if I would mate with this emotionless she-cat!" Rin yelled, pointing at said she-cat.

Haru just blinked and pointed at herself, her face expressionless.

"But, Onii-chan, you love Onee-chan, don't you?" Kokoro asked.

"Shut up!" the redheaded cat ordered, blushing slightly from her question.

"I didn't hear you deny it, tsundere kitty." the violet haired kitten pointed out, snickering behind her hand.

Rin growled at her through his shark-like teeth for a moment before he turned his attention back to the young woman. "I won't make any noise again!" he vowed. "Will you let me off the hook if I promise that was the last time?"

"Well..." Toko started to say, considering it.

"Please don't take me to the hospital..." the male cat begged, now on his knees as tears pricked the corners of his eyes.

The cat owner sighed. "Alright, we'll give it a try." she said. "However, if you get noisy again, I will most certainly take you to the hospital." she told him seriously. "Do I make myself clear?" she asked.

"Yes, ma'am..." the redheaded cat replied.

Haru and Kokoro just stayed where they were as they watched the scene in front of them, a look of amusement on the kitten's face while the older cat's face was blank.

At night, in the bathroom

'Damn...' Rin thought to himself as he a took a cold shower. 'Even a cold shower isn't doing anything. If this keeps up, I'm not going to be able to hold myself back until the mating season ends.'

Then, in hopes of keeping his hormones downs, the male cat grabbed his cock and starting stroking himself, panting a bit as he did so.

'Why am I the only one who's in heat?' Rin asked himself mentally. 'I understand why Kokoro isn't affected, she's still a kitten. But, how come isn't Haru affected by this? After all, she's a grown female, .' at that thought, an image of the beautiful female cat entered his mind. "Shit!" he cursed aloud, stroking himself harder and faster.

Suddenly, the sound of the doorknob turning reached his ears.

'Crap! I forgot to lock the door!' the redheaded cat thought in distress. "Uwaaah!" he cried out when the door opened.

Haru, wearing nothing but a small towel around her body, walked in and saw that the male cat was on the floor.

"Rin, I would like to take a bath, so can you please get out?" the ravenette cat asked him bluntly in monotone, her face expressionless. "You've been in here for quite a long time." she remarked.

However, Rin, whose whole body froze when he saw her, wasn't listening to her. He was only paying attention to the beautiful cat with a beautiful body, taking notice of how the towel stopped at her thighs, showing him her long, smooth legs, and showed him an incredible view of her very large cleavage. Haru became slightly worried when the male cat didn't say anything for a while. He was just staring at her.

"Rin?" the female cat questioned as she walked up to him. "Are you alright?" she asked, placing her hand on his shoulder.

Upon feeling her touch, Rin broke out of his trance.

"Don't touch me!" he yelled as he threw his elbow back, accidentally hitting the lever and turning on the shower. "Ahhhh!" he exclaimed when he saw the water fall on top of the ravenette cat.

When the water from the shower hit Haru, her towel clung to her body like a second skin. Then it came lose and slowly slid off her body, falling onto the floor. The redheaded cat quickly turned the lever, turning the shower off.

"Geez..." Rin mumbled as he tried not to look at her naked body, but ended up failing. "You were suppose to leave..." he said to the female cat, who was coughing slightly. "Are you okay?" he asked when he noticed that she wasn't moving.

Haru raised her head and looked at him.

'Huh?' the male cat thought when he looked into her beautiful, ocean blue eyes. 'What's with that weird look in her eyes? Or am I just imaging it?'

Suddenly, the ravenette cat leaned towards the other feline and started to sniff him.

"Oi! Don't come at me so suddenly!" Rin told her, blushing from her close proximity.

However, Haru ignored him, placed her hands on his shoulders, and pushed him against the wall.

"What the hell are you doing?!" the male cat yelled.

The female cat ignored him again and pressed her naked body against Rin's, making his face turn a very dark shade of red.

'What the hell is going on with her?!' the redheaded cat thought, completely shocked by ravenette cat's sudden change in behavior. Suddenly, a strange smell hit his nose. 'Wait, this smell... It can't be...' he visibly paled. 'She's gone into heat?!' he mentally exclaimed. 'What kind of situation is this? Why did she suddenly go into heat? More importantly, this position. Is she planning on doing me?'

Haru placed her hands on Rin's chest, bringing him out of his thoughts, and started to lean closer to him, her lips very, very close to his. A second later, the female cat placed her lips over the male cat's, kissing him passionately.

'What the hell is happening?!' Rin thought, beyond shocked. Despite himself, he couldn't help but think about how soft and sweet her lips were. After a few moments, the male cat finally got over his shock when he felt her slid her tongue into his mouth. 'Enough of this!' he mentally exclaimed. He pulled his mouth away from her's. "Get off, Haru!" he yelled as he tired to push her away.

Then, much to his surprise, the redheaded cat felt something very soft in his hands. Rin soon saw that his large, calloused hands were touching the female cat's large, soft breasts. His face got super red when he saw his hands on her breasts, which he had wanted to secretly touch for years. Then, with some reluctance, he removed his hands from her breasts. However, the action Rin just did, turned Haru on even more.

The female cat leaned forward and started to kiss the male cat's neck. Then she got lower and kissed his chest. Rin's body went stiff when he felt her going even lower. He realized what she was about to go.

"Hey, don't go there!" the redheaded cat yelled.

Haru ignored him, got down on her knees, and spread his thighs apart. Then she stuck out her tongue and started to lick the male cat's hardened cock.

Rin's whole body froze. 'If this keeps up, I won't be able to control myself.' he thought. 'Must stay in control. Must stay in control. Must stay in control.' he repeated in his head, gritting his teeth together.

As the male cat thought, Haru stopped licking his cock. Then, much to his shock, he felt the female cat take his cock into her mouth, sucking on it. That was it for Rin, he snapped.

'Screw control.' he thought, deciding to give the ravenette cat exactly was she was asking for.

After a moment, Haru removed her mouth from the male cat's dick. The second she did, Rin grabbed her shoulders, pulled her up, and switched their positions, her back now against the wall.

"Goddamn it, Haru..." the redheaded cat said as he started to kiss her neck. He pressed his body against hers and kissed her passionately as she wrapped her arms around his neck and pulled him closer to her, their tails entwining with each other.

As the two cats kissed each other, Rin slid his hands down Haru's body, tracing every curve she possessed, including the ones he had been thinking about since they were children and when she had started to develop into a woman.

"You're so beautiful..." Rin whispered into her shoulder whenhe pulled away from her mouth, kissing it soon after.

Then he gently laid Haru down on the floor and continued to kiss her relentlessly. As the male cat kissed her, he started to massage her large, erect breasts, which caused her to cry out a moan-like meow. The noise turned Rin on even more, bringing out his primal, animal urges.

Turning her around, the back of her body now facing him, the redheaded cat gripped the female cat's shoulders. Then he thursted into her from behind, causing her moan out loudly. As he continued to thrust into her, Rin leaned forward and sank his teeth into the back of Haru's neck, his hands leaving her shoulders and going down to her breasts, which he fondled softly.

Meanwhile

"I thought I heard something earlier..." Toka said to herself as she walked down the hallway, rubbing her eyes. "Could I have imagined it?"

Suddenly, a strange sound reached the young woman's ears.

'It's coming from the bathroom.' Toka thought to herself when she turned her head and found herself staring at the bathroom door.

Back inside the bathroom

Rin moaned as Haru rode on his cock, her hands gripping his shoulders tightly as her legs straddled his waist.

"Go more slowly..." the male cat told her.

As she continued to ride him, Rin leaned closer to her chest, licking one of her hardened nipples before he took it in his mouth and sucked on it. One of his hands went to her other breast and started to massage it. Haru gave a small moan-like meow from his actions, soon reaching her climax and cumming on the male cat's cock.

"Haru..." was all Rin said when he released her nipple and looked up at her.

The female cat stared at him for a moment before she leaned down, covering his lips with hers. The redheaded cat didn't hesitate to kiss her back. Suddenly, one of his ears twitched.

"Crap!" Rin yelled when he pulled away from the ravenette cat, looking towards the door. "Toka's coming!"

Haru ignored him, grabbed both sides of his face, and pulled him back into a passionate kiss. The male cat moaned when he felt her tongue slide into his mouth, clashing with his own tongue in a fight for dominance.

"Rin-chan?" Toka's voice was heard from the other side of the door. "Is that you in there?"

Instead of answering, Rin continued to fight against Haru's tongue with his own. In the end, he won and explored every corner of her the female cat's mouth.

Outside the bathroom

"I'm going to come in." Toko stated as she grabbed the doorknob and twisted it. "It's locked." she said when the door wouldn't open.

Back inside the bathroom

When she pulled away from the male cat's mouth, Haru turned her head towards the door.

"Meow." she meowed.

"So you really are in there." Toka's voice was heard from the other side. "You shouldn't be playing this late at night." she scolded. "And please keep the noise down, I don't want you waking up Haru-chan and Kokoro-chan. Go to bed now, okay? I'm going back to my room. Good-night."

When the sound of the young woman's footsteps were gone, Rin didn't hesitate to grab Haru by her shoulders and push her to the floor. With his hands pinning both of her wrists above her head, the redheaded started to thrust into her. The ravenette cat moaned loudly as he thursted into her. Both of them moaned when he cummed inside her.

You would think that it was over, but it was just the beginning. After Toka left, I started to thrust into Haru even harder. And I kept doing it, until I passed out...

Outside the bathroom

The door opened and a certain female cat walked out calmly, leaving a certain male cat unconscious on the bathroom floor
