I freaking love Shizuka nekonome, I find her a fun character and very tasty looking, yet she has almost no art. It sucks. So I wanted to add some nekonome vore. Also if you are wondering about tsukune being a vampire or the future headmaster, go read the manga. It's way better than the anime and has an actual story.

Tsukune panted for breath, an entire litre of water pouring down his throat. He cast the crushed empty bottle aside, panting heavily.
"So thirsty, so hungry." he groaned, his throat painfully dry no matter how much he drank, his head felt light. He knew why his body ached so much. He wasn't human anymore, he was a vampire, he needed blood but refused to drink it. This wasn't the first time his body had started causing him so much pain, it wouldn't be the last. He needed blood. He had to be careful around his friends, every time he was near them, his mouth watered, and his stomach growled for blood...he hoped it was just blood at least, for some reason lately he'd been feeling more hungry than thirsty He grabbed another bottle this time of juice, he brought the bottle to his lips with shaking hands.
"GAH! I need to find something to do, something to take my mind off how hungry I am before I go mad." he panted wiping away some of his white hair away from his face. He tossed his empty bottle into the nearby garbage can, a pile of dozens of crushed cans and bottles he'd emptied over only half an hour.

Tsukune wandered through the halls of Yokai Academy, his mind struggling to think of anything but his hunger. The young vampire ended up in one of the school's offices for the teachers. His mind finally snapped back to reality at what he found, at the far end of the room was one of the school's teachers, Shizuka Nekonome. A Neko-Musume in her forties, with short blonde hair, despite being a teacher who taught students to keep their human form she never kept her own, or at least not fully. Her cat ears and tail were never hidden. She wore a tight-fitting orange striped blouse and equally tight short black skirt and a pair of pink framed glasses, her tail sweeping side to side from under her skirt, her golden ears twitching occasionally. Nekonome was crouched in front of a shelf of books, her butt swinging as she looked for something. Her tail and butt swung in opposite directions as she searched for some particular book. Tsukune felt his mouth water seeing her plump rear shake, his red eyes locked on the soft rump. His stomach growled looking at her. Nekonome was attractive, though nothing compared to many of the girls of the school including his harem, but she was still rather attractive, with a slender figure, D-cup breasts, a pert butt, and a slender pretty face. Without thinking Tsukune approached the teacher, saliva trickling down his chin, his hand reaching out absentmindedly.
"NYA!" Nekonome meowed in shock as his hand groped her ass. She shot up with a blush, her blue cat eyes darting behind her to see who was groping her, not that she minded. At her age and being surrounded by dozens of beautiful women she didn't get much attention, so someone groping her was a pleasant surprise. Though it was a surprise to find Tsukune of all people feeling up her butt.
"Tsukune! As both my student and future boss, you really shouldn't be pawing at me like that. Not to mention the fact you have an entire harem to enjoy. I'm sure Kurumu or Ruby would be happy to have you grope them to your heart's content." she teased while not doing anything to make the young man stop.
"Sorry, I don't know what came over me. I'm so sorry." He tore his hand away, much to the teacher's disappointment. Nekonome brought a hand up to his face playfully, even rubbing her head against his cheek as best she could with the height difference between them.
"I didn't say you had to stop. At my age, it's nice to see I can still have that kind of effect on people, especially on someone like you who has girls fawning over you. Go ahead, no need to be shy." she purred happily before bending back down, making sure to shake her behind for the young man. She could hear him panting behind her, his hands reaching down to caress her. His hands snuck over her smooth silky skin, one hand pulling her shirt up and rubbing her stomach, the other squeezing her supple thighs. She couldn't help but purr at such affection, one of his hands moved to her chest and began to grope her deceptively large breasts. Sure compared to many of the girls at Yokai Academy they were small, but they were still nothing to scoff at, she couldn't help but smile, knowing that someone was finally appreciating them. His hands dragged across her body as he pulled away, she couldn't help but pout feeling his strong hands stop caressing her.

Tsukune watched his cougar of a teacher shake her butt for him. His stomach growled again, hunger flooding his head.
"She looks so tasty, feels so soft, so creamy..." his mouth watered looking at her.
He pulled close to her, his mouth opening wide as hunger took over. His mouth wrapped around her soft rump, saliva soaking through her skirt in seconds. Shizuka meowed in confusion, his lips passed over her soft thighs and back.
"What, what are you doing back there?" she mewed. He swallowed more of her soft body, her tail slurped into his maw, his lips forced her chest and legs together, and she could feel her feet leaving the ground. Tsukune ignored the teacher's words, his mind only on consuming her soft delectable body.
"Oh...you're eating me. Well, this is a surprise." Nekonome laughed, she didn't fight against the approaching maw. A flint of thought flickered in the vampire's eyes, a look of remorse for what he was doing. "Awe, don't sweat it Tsukune. You don't know this due to being human until so recently, but this kind of thing isn't that uncommon. We had a student a few years ago who ate about a dozen girls in one year here, including a teacher. We had to put a limit on how many girls he was allowed to wolf down. There are a few species of Yokai that like to gobble people up whole, though I don't think I've ever heard of a vampire doing it before, than again you're an oddity among vampires. Some Yokai species tend to end up in stomachs as well. Like Succubi, when Kurumu's mother was in school, she had seven sisters at the school with her, she was the only one who actually graduated. Most of the students who do have this kind of appetite tend to eat the monstrals, witches or mermaids. Most Monsters aren't too kind to them. Though apparently, this kind of thing is rarer than it used to be." she explained as Tsukune continued eating her, his fangs scraping gently across her back, her legs leaving the ground entirely. Her body sandwiching against itself, his tongue licked across her creamy skin.
"You know, when I was a student, I was actually annoyed that no one ever tried to eat me. When we had that student I told you about I secretly hoped he'd eat me, especially after he ate Niku. He even taunted me, he brought his big belly to class with her still digesting. It was hard to stay focused that day." the teacher moaned happily. "So there's no need to rush or worry. I'm all your's Tsukune." she cooed. Despite his hunger, the young man took the time to truly enjoy her. He ran his hands across her smooth legs, kneading the soft flesh before it became his meal, taking the chance to grope her boobs again.
"Good boy. No need to be worried, just a tasty kitty who wants to be snuggled up somewhere warm." Shizuka purred sweetly. Tsukune slurped her deeper, her knees slipping into his mouth, her breasts squishing against her legs as his lips passed over her shoulders.
"Nya, how nice. This feels even better than I expected." she purred tenderly. She watched as her favourite student's lips entered her vision, saliva dripping across her face, his teeth starting to block the room from sight.
"She's so soft and creamy, and so willing. I don't get why she's enjoying this, but I'm glad she is." he brought his hand to her unconsumed chin, playfully scratching it much to Shizuka's elation, she purred loudly at his scratching. "I feel bad about this, but she's enjoying herself. She said this was rather normal. I should ask Nurari, or maybe Ruby? No, Ruby's probably a bad idea. With that level of masochism, she'd probably beg me to eat her, and I'm not sure I'll have the will to say no for long after this."
He tossed his head back, despite how wrong this all seemed to him on a moral level, his body seemed to know what it was doing, every movement making the process of turning his teacher into food easier. Nekonome's head slipped into his mouth and quickly his throat, with the best of the Neko done, he simply slurped her silky legs down like long meaty noodles. He watched as her kicking feet vanished from his view, sliding easily into his mouth and slipping down his throat to his waiting stomach.

Nekonome squirmed slightly to adjust her body now that all of her was eaten.
"Ah, tight, warm, soft and hungry. I couldn't ask for a better stomach to digest in. I never would have guessed Tsukune to be this kind of boy. But then again I never figured he was a human or would go on to fight Alucard and help save both the monster world and the human worlds. So I guess that's my own mistake. I do hope he enjoys me and doesn't beat himself up. With his condition as a vampire and not drinking blood, he's probably been starving himself for months. Well, I'll fix that up." she smiled to herself. She ran gentle hands across the pulsing hungry stomach walls. She could already feel the acid starting to form though it was only a slight tickle at the moment.
"I wonder how long it'll take him to digest me. I know some more experienced carnivores could digest girls in just a few hours. But this is Tsukune's first time, though I hope not his last. So his stomach probably won't be able to digest me as easily, plus with my age, I'll be a bit tougher to digest than some fluffy marshmallow of a teenager. Plus like I told him, the more common meals were low-level monsters or humans both of whom digest rather easily. Hmmm. I might be in here for a while before he's done mushing me up," the cat girl turned meal couldn't help but snigger, "Not that I mind."
Her soft resting place shook wildly suddenly, a thunderous belch ringing through her ears.
"Ahah, that's an impeccable burp Tsukune. Never feel ashamed about letting out a burp after gulping a girl down, the louder the better," she called though she had no idea if he heard her or not. It didn't matter either way. Her only concern was digesting and feeding the young man. She nestled herself against the soft rippling flesh with a beaming smile and a purr.
"Ah, this makes me feel like a teenager again. Though I'm glad it was Tsukune that ate me. I won't just be a tasty snack for him. He'll remember me for the rest of his life, and the fact I got to pop his cherry for eating someone." she chuckled to herself, "This is perfect."

Tsukune rubbed his stomach with a weak groan, his throat hurt not from eating something so large, but more from the burp that came after.
"So big, and so wrong. But, she tasted so good. No! I need to find a way to get her out. It doesn't matter if she tasted sweet and fluffy. If she feels perfect and filling in my stomach. Sooo- NO! I have to get her out, this is wrong."
"No need to get worked up about it kid." a gruff voice chuckled behind the vampire, he spun as best he could to the speaker.
"Nurari?" he stammered out timidly, "I-I can explain."
Standing behind him was a tall man with pale skin, he wore a purple suit with a matching cap that made it a striking uniform while also covering part of his face save for his eyes. A large cigar burned in his mouth, smoke puffing out with every breath. A pair of intimidating glowing eyes pierced into the young man's soul.
"I said don't sweat it. You're not the first and you won't be the last person to eat some hot babe up. Though you are the first in the last few years and the first to eat a teacher since Niku got herself eaten. But you're not going to get in trouble for it, besides, who would punish you? Yourself?" the demonic bus driver laughed deeply at his own joke, "Though that you ate Shizuku, now that is more of a surprise and a shame. Oh well." Nurari shrugged with a cold smile, Tsukune watched as he pulled a card from his pocket.
"If you end up eating someone else and the school police or a teacher try to stop you or give you trouble, just show them this card. If anyone's earned the right to enjoy a girl for lunch it's you." Nurari laughed as he handed the card to Tsukune.
"I'm not going to do this again. I...I don't even want to digest Nekonome. But I don't think I'll be able to get her out." Tsukune rubbed his stomach remorsefully. The bus driver burst into a fit of booming laughter.
"That's a good joke kid. But I don't buy it." he pulled a picture of an attractive woman in a skimpy bikini out, Tsukune felt his throat tighten and his mouth water just seeing the picture, despite his full bloated gut, he felt hungry just looking at her.
"That's what I thought. Just try not to eat too many girls. Now," Nurari hefted the boy to his feet with ease, "let's get you to your dorm or your office so you can digest Shizuku in peace. Unless you'd rather do it in one of your girlfriends' rooms." the older man teased with another laugh.
"Please don't tell them." the boy whimpered.
