I am Succubus!

I put the thoughts of last night behind me as I head to school. It's just a one time thing. It had no meaning. Even if it did, Mio's a girl so that means I'm still safe.

But the feeling of her tail inside me was kind of wild… that was the second time in one day it went up my pu— vagina. And the third time I orgasmed in one day.

Oh, god. It was only day one of being a succubus, and I had more action in one day than I did the last 18 years. Was I really that much of a failure as a guy? 

By the time I get to the school gates, Mio has disappeared. She's probably off to cause god knows what trouble. Maybe it won't be so bad at school without her presence today. She nearly caused an uproar when Kana and Shirai walked in on us in the Nurse's office.

"Speaking of, I gotta get them their handouts." 

The handouts Sensei gave were just a survey form asking about our future. Nothing like our career or university plans after high school, but just what we'd like to do in general. Hobbies, goals, interests, stuff to follow through while we're wasting away at University or working.

I find Shirai changing into his indoor shoes and give him his handout. I wonder if he remembers what happened yesterday?

"Oh, thanks for this!" He says looking over the piece of paper.

I test the waters and ask, "I heard you brought Kana to the Nurse's office yesterday?"

"Huh? Oh, yeah. Can't really remember much though. Memories' all blurry. When I woke up, Naruse said I just had a heatstroke."

"I see. How was the Nurse and Principal?"

"Principal? Was he there?"

"Er, maybe I was just imagining things!"

"You were in there, too, right? You left class before P. E."

"Yeah, but I kinda fell asleep. I saw you and Kana lying on a bed when I woke up. When I headed back to class, that was when Sensei gave me the handouts."

"Ah, well. Thanks again. I'll see you in class."

I decide to head to class too. I find Kana inside sitting in his own seat for once. He looks deep in thought.

"Kana, I have your printout for you."

"Thanks." He says, spacing out. "Hey, you went into the Nurse's office yesterday, right?"

I freeze as soon as he asks that. I try to reply back as calmly as possible. "Why do you ask?"

"For some reason I don't remember… I only sprained my ankle but I feel like I'm forgetting something. I think I saw a girl with horns and wings… like a succubus?"

"You had a heatstroke. It was probably just a hallucination!" I try to cover for his fragmented memory.

"Maybe."

The school bell rings and Sensei comes in telling us to settle down. Everyone gets to their seat, and he stands at the podium with an announcement. "So, today we have a new student joining our class. Please, come on in and introduce yourself."

The door slides open and the one who enters is the last person I was hoping to see— 

"MIO?!" I jump from my seat. Every pair of eyes in the room turns to me, and then flips back to Mio.

She's wearing the standard school uniform, none of her succubus features are showing, and there is a wicked smirk on her face. Mio waves back and blows me a kiss. All the boys in the class go crazy, and Sensei has to raise his voice to calm them down.

Mio comes to the front of the class and says, "Nice to meet you all. My name is Ito Mio. As you can guess, I'm Saeko's cousin. My favorite hobby is being naughty and causing problems! Teehee~"

The class goes into an uproar again with the girls joining in this time. A lot of hooting and hollering, and boys asking for her number from their seats. The moment Mio walked in, she became the most popular kid in class.

Sensei is rubbing his head. "Hopefully you behave yourself and don't cause problems while class is in session."

Mio winks at him. "Aw, Sensei! Does that mean we can be naughty with each other outside of school?"

"A-alright, enough of that! There's an empty seat in front of Saeko." Then he turns to me with a stern expression. "Saeko, I expect you to keep your cousin under control."

I sink into my seat with embarrassment, "Yes, Sensei…"

***

I was hoping to get a word in with Mio by lunch, but it doesn't look like I'm getting that chance. Currently, Mio is being swarmed by the class. So much so, that they've crowded around my desk, and all I see are their backs.

Mio is reveling in her newfound attention. A bunch of girls are asking her to go karaoking with them, while the boys are trying to ask her for her number and line— neither of which she has. 

"Mio, how do you get your hair to be so pretty?" 

"Are you single?"

"Have you ever had a boyfriend?"

"Where are you from originally?"

"What are you doing after school? Let's hang out!"

Mio brushes off most of the questions, and some she doesn't answer outright. "Sorry, everyone. As much as I'd like to hang out with you all, I have to stick with Saeko wherever sh— he goes."

There is a simultaneous 'awww,' that erupts from the crowd. Some of the students start begging me to hang out with them just to get to Mio.

I get up from my seat. "Mio… can we have a chat outside?"

I pull Mio out of the classroom and have to shut the door close on my classmates following us out. We go all the way to the top of the school roof to speak in private.

"What's up?" She asks, oblivious to my worries. "Oh? Did you take me out here for round two? I'm so down to fuck you again!"

"Wait— no! That's not why I brought you here." I point to her getup. "THIS! Why are you suddenly a student here?!"

"I got the fatso to put me in."

"Principal Murata? I thought you released him from your charm?"

"I did. But it didn't take much convincing from little ol' me."

I squint my eyes at her. "What exactly are you plotting?"

Mio whistles into the air, "I have no idea what you're talking about. I'm just here to get an education!"

"No, you're not. You're definitely here looking for someone to have sex with."

"Teehee!" She sticks her tongue out at me, but the sight of it makes me blush now.

"Wait a minute, how old are you in your world anyway?" At a quick glance, Mio looks like she would be in college or a young adult in the working class.

"We don't keep track of ages in my world, but I know for a fact I'm older than you."

I sigh and scratch my head. "I don't know what you're planning but you better not—uwah?!"

She reaches under my uniform and towel to pinch my nipples. She teased them so much yesterday that they're still sensitive now. Just wearing the towel makes me feel weird. "Come on! Let's play♡!"

"No… we don't even have enough time right now— ahh!" A cold hand slips into my pants and starts rubbing my clit.

"Better yet," Mio says, "Why don't we find a lucky boy to have a threesome with? Maybe that Kana kid…"

"Guh… nnnngh! Don't… bring Kana into this— haahh…"

Mio leans in and whispers into my ear. "If you thought getting fucked by my tail felt good, imagine a big… hot… cock being stuffed into your pussy." 

Kana's thing… in my...

"N-no!!" I push her away and make some distance between us.

I try to steady my breathing and recompose myself. Images of Kana and the Principal's penis, as well as the thought of having something like that in me is making me feel oddly excited. 

"There's no way I can have sex with him…" I say with a hint of unease.

"Kahaha! Time to head back to class or else we're late, right?"
