Koneko was horny. She had recently walked in on her older sister masturbating to thoughts of Issei, and, to her surprise, joined in. But that wasn't enough for Kuroka. She had recently taught her little sister a technique that was meant to be used in battle. But like most demonic magic, there was a perfectly suitable secondary use for it.

Kuroka opened the window, letting the flow of nature surround her. Koneko, naked beside her sister in one of the Hyodo house's many bedrooms, channeled her spiritual power. She activated Shirone Mode, transforming into what she'd look like in a few years. Koneko was momentarily thrown off balance by the added weight in her breasts and butt. As she was a cat, she landed on her feet.

"You look beautiful, Shirone," said Kuroka.

"I can't hold this form for very long," said Koneko, giving off a whitish-gold glow from her body.

"It's a shame. Look in the mirror while you can," said Kuroka. She placed her fingers in her sister's pussy, and spread apart the lips. They were still fresh with juice from her masturbation session. And were now secreting even more than they had before. Koneko felt a chill run up her body, overwhelmed by the sensation of Kuroka's fingers. Her nipples stood on end. "Your pussy looks so plump and mature. I love it."

The fullness of her lips, pink and dripping, captivated Koneko. The two sisters' sense of smell was heightened by their nekomata nature. They could smell sex all around the room. The smell of their own sex. And like anybody, they loved their own brand. Koneko, overcome with lust, reached for Kuroka's labia and started stroking, teasing out her older sister's clit.

They stood there in the moonlight, gently masturbating until their bodies went numb with pleasure. However, Koneko had not counted on her sisters' mischief. Kuroka teased her sister's pussy, covered in light silvery hair, until Koneko was on the brink of orgasm. She could feel the hard, throbbing pulsations of her clit echoing in her loins. She wanted to spray herself in the mirror, to mark her own future beauty with her own scent.

Koneko returned to her regular size. While she'd lost her proprtions from Shirone Mode, the arousal lingering in her pussy remained. All she had to do was touch her clit, and she'd orgasm so powerfully the whole house could hear it. But, using her older form had worn her out. Instead, she collapsed onto Kuroka's bed, snuggling in her older sister's breasts. Koneko's tongue gently lapped at Kuroka's nipples. Kuroka patted her sister's head, and fell asleep alongside her.

Koneko couldn't focus the entire school day. She was overcome with an urge to rub against the corner of her desk, marinating it in her juices. She kept squeezing her legs together, hoping to rub them enough to bring on an orgasm. She was jittery the entire day. There had to be someone she could talk to about this who would understand her. That feeling of having a libido, but not being able to properly control it.

So she entered the Occult Research Club room. A cardboard box, holding a student with a paper bag on his head, dressed in the girls' uniform, was waiting. For a meeting, or anything, to begin. He was a dhampir, and the only other first year student in the club. He was someone who wouldn't tease her about her problems.

"Gya, I need your help with something," said Koneko. She gently rustled his hair. He stood up from the box, looking around the room for a moment before stepping into the wide expanse of the club room.

"Is it an emergency?" asked Gasper.

"It's a personal emergency," said Koneko. "We don't need to mobilize the whole club."

"I thought things like this were why we called Issei," said Gasper. "He can do just about anything!"

Koneko sat down on the couch and poured a cup of tea for herself. "Issei's but a child compared to us. His libido is too out of control, and my body can't handle his cock yet. Not that I'd want to think about that."

"Issei's penis..." Gasper said with a daydreamy tone.

"Excuse me?" asked Koneko, quickly swallowing her tea.

It was after another one of the Occult Club's training expeditions. The members had split off at the hot springs, with the boys going into one bath and the girls going into the other. The baths were separated by a wooden wall that allowed the conversations from the other side to be heard. However, the girls were exhausted from training, and felt like relaxing in the water while barely saying a word to each other. Issei was still pumped up from training, and was the first to lead the conversation on the boys' side of the baths.

"Just think of what's on the other side!" said Issei, standing up in the middle of the hot springs. "A wonderland of girls, their boobs floating on the water. When they stand up and feel the cool breeze on their swaying breasts, their nipples become hard, shining like cherries on top of pudding!"

When Issei had stood up, he was limp. Gasper, who had been watching with his head half-submerged in the water, was at eye level with Issei's penis. He had never taken a close look at it before, but that was because Gasper had barely made eye contact with anyone until very recently. The idea of seeing such an intimate part of the club member he admired this close made him feel embarrassed, like he was breaking some sort of unspoken taboo. Issei didn't notice. His eyes were staring towards the wooden wall and his head was in a cloud of fantasies.

If Gasper had looked into Issei's eyes, he would've seen Rias' nipples reflected in his pupils. The imagination was a powerful tool for one's lust, and Issei's love of the bosom was boundless. The more he kept extolling about the archipelago of breasts waiting on the other side of the hot springs, the more his body responded.

Gasper could faintly sense the flow of blood beginning to swell in Issei's loins. Gasper opened his mouth in awe as Issei twitched, before springing to life. The length, the girth, the pale red color in his glans, all of it was drawing Gasper's attention. It stood at an angle, pointing towards the wall separating the baths like a divining rod. When Issei turned to face Gasper, who was blushing hot, Gasper briefly saw Issei's cock swing towards his face before turning away, hiding more of his body under the water.

"What is it? Something on my face?" asked Issei.

"It's impressive..." said Gasper shyly.

He had been living with Yuto for a little bit, but they had mostly kept to themselves. Compared to Issei, Yuto's libido wasn't quite as strong, and Gasper had only glimpsed his penis when he was coming out of the shower on a few occasions. He wondered what he might have done had it been right in front of him like Issei's was now.

"Issei, I want to..." Gasper's mouth buried the last part of his sentence with a garbled mess of bubbles.

Without thinking, Issei's hand moved towards his shaft. He gently rubbed the length of his cock. Gasper could see the veins and the trembling balls, faintly throbbing with the blood of arousal. Issei had told them the story of the time he tried to masturbate with his newfound demonic powers, and realized that doubling in size shouldn't be applied to everything. All he said was that it was too big to fit inside Rias, and he had a good idea of what Rias' red-haired garden looked like, having seen it the first time she slept over.

With his mind filled with images of bouncing bosoms, Issei's penis splurted its milky-white cum into the hot springs. It dissolved into the water, drifting around. Gasper wanted to grab some of it on his fingers, but with Issei retreating to the edge of the baths, his cock starting to soften, he couldn't work up the courage. The last drops of cum fell from his head, filling Gasper's nostrils with the scent of his manhood.

"Don't do that in the bath!" Kiba said.

"I'm sure the girls are shlicking on the other side," Issei said.

Gasper declined to comment.

"That's it?" asked Koneko. "We've all accidentally seen Issei's cock at some point."

"I want to see it deliberately," said Gasper. "And maybe... do something that might make me more of a man. The vampire within me wants to have that pulsing, throbbing iron rod in my mouth. But I also want to sate my libido with Issei's libido. I want to see him masturbate... masturbate alongside him... and when he needs somewhere to shoot his semen, I'll offer my mouth."

"I thought you were a dhampir, not an incubus," said Koneko dryly.

"I admire Issei a lot, but I didn't think it was sexual," said Gasper. "I don't have the courage to masturbate with him."

"You've never rubbed one out on your own?" asked Koneko.

"It's not that I haven't," said Gasper. "What if my cock is too small? Issei's packing, and Yuto's pretty sizable, but then you come in here and say you want to take pity on me because I'm small?"

Koneko realized that she may not have chosen her words properly. In a way, she could relate to Gasper. There were plenty of girls in the Occult Club, and she had felt a similar sense of inadequacy on that same day in the hot springs. Asia was only average-sized, and she was small, compared to Rias, Akeno and Xenovia's buoyant bosoms.

"That's not what I meant," said Koneko. "It's because I trust you. You're someone I can talk to when something's bothering me, and we're in the same year. There are things only us first-years can relate to that Issei wouldn't get. You're the gentlest, cutest vampire I know."

Koneko reached underneath her skirt and removed her panties. They had a kitten print on the back, yet were otherwise white and frilly. She stretched them in her hands. Her body heat remained on the fabric, along with the slightest trace of her aroused scent. Gasper and Koneko both had strong senses of smell. With her loins freed from the cloth, the sweaty, feminine smell of Koneko's kitty spreading through the room. Some of it had become trapped in her thin, soft layer of silvery pubic hair. It wasn't much, and was only visible under the right kind of light, but Koneko's fur was one of the few things on her body that made her feel mature.

"Koneko, what are you doing?" asked Gasper.

"Gya, come over here," said Koneko. "And take off your panties. I can see your bulge pushing up your skirt."

Koneko was familiar with this, because the panties Gasper was wearing had once been her own. He only had so many from being sealed inside the academy for so long, and Koneko, being about the same size frame, had no problem with lending her spares. Gasper came over to the couch and removed his underwear.

Koneko took a deep whiff of the inside of the panties, feeling Gasper's body heat. "It smells like precum," she said. "Otherwise, they're nice and fresh. I'll get this little stain out."

Koneko licked the inside of Gasper's panties, tasting the faint mixture of his salty sweat and precum. The taste lingered on her breath. Koneko looked down happily at Gasper's loins. His erect cock was throbbing, his balls gently shaking with excitement. Precum continued to drip from his cockhead, covering his shaft with a faint, shining line that stood out in the light of the club room.

"Koneko... That was sexy," said Gasper.

"Come over here," said Koneko. "I don't know if I want you inside me... but do you want to masturbate together? I'll stroke your little man, and you can put your fingers inside my pussy. Someone else's hand feels better than your own."

"You'll let me do that?" asked Gasper.

"I'm really horny, of course I want to do it!" said Koneko. "Show me what those fingers of yours can do."

Koneko and Gasper's arms crossed. Her palms, as soft as cat paws, wrapped around Gasper's cock. He rubbed his fingers around Koneko's pussy, teasing out her clitoris. Koneko gently moaned. She felt her love juice starting to trickle out between her legs, staining her thighs and the couch. It had a faint smell, one that the duo's sensitive noses could detect. It was undeniably the scent of arousal.

One of Gasper's fingers gently rubbed around Koneko's wet lips before slowly sliding inside. His other hand danced around her clitoris, while the back of Gasper's palm was gently brushed with her pubic hair. Koneko's soft pubic hair that felt like a cat's fur, combined with her pussy that was as squishy as a cat's paw. Gasper loved the way, when he squeezed the outside of Koneko's pussy, that a faint squishing noise could be heard, and her outer lips were coated with love juice that overflowed from inside.

Koneko gently wrapped her hands around Gasper's cock. His balls had tensed up, already throbbing with the incoming pleasure of ejaculation, bringing them close to Koneko's palm. She was surprised at the sturdiness of his penis. Even in the dim light of the room, she could tell it fit comfortably in her hands. It was uncut, too, and the natural lubricant within made it easy for her to slide. She felt its warmth between her curled fingers as Gasper moaned, approaching climax.

The two of them panted. Awkwardly, out of sync, moaning to only an audience of each other. Their lower bodies were numb with pleasure, each of them trying to hold out on their orgasms for a moment longer so they could continue to enjoy each others' touch, fumbling around their loins gently and kindly. Koneko had masturbated plenty of times before, but she had never been able to squirt.

The puddle of sweat and love juice underneath her butt made it feel like she was sticking to the couch. This corner of the club room smelled of sex and sweat. Koneko felt her nipples harden, pushing against the fabric of her bra. She wanted to unbutton her shirt and free her bosom, but she couldn't stop stroking Gasper's penis, pushing him closer to an orgasm. She clenched her legs together, trapping Gasper's fingers inside her crotch until he could leave her satisfied.

Koneko and Gasper turned around and longingly stared each other in the eyes. That final push brought them both to climax. Tiny spritzes of nectar spurted out of Koneko's pussy while her clitoris throbbed with a heightened sensitivity. Gasper's cock painted Koneko's hand with an off-white layer of pearlescent cum, rich and raw in its scent and sticky to the touch. The two of them pulled their hands away from the others' loins and looked towards the ceiling, breathing heavily and taking in the warm sensation spreading across their bodies.

"That was the best sex I've ever had," said Gasper. "It's different from drinking blood. I don't feel powerful, but I do feel... good."

"You kept focusing on my clit. You want to lick me down there next time?" asked Koneko.

"I... don't know. Am I the right size for you?" asked Gasper.

Koneko licked Gasper's semen off her hands. The taste was slightly bitter, but once she swallowed, the warm feeling in her stomach left her with a fullness she had been missing. She looked at Gasper's limp cock, resting on the edge of his panties. It looked cute, but she knew that "cute" wasn't the word Gasper wanted to hear. He had been listening to Issei talk too much about being "manly," and it had started to play with his expectations.

"There's someone in Issei's class who can calm your mind," said Koneko.
