If you're interested, make sure you say whether you're an instructor or a student, and if you're a student say whether you enrolled willingly or were forced to c;

(As the Head Mistress, I'll get us started with a back-to-school assembly, but as people join, we can move to a classroom to get more "in person")

*A large assembly hall, filled with rows and rows of students. They are wearing the revealing school uniforms, including string panties that barely cover their pussies and asses and form fitting tops that cling tightly to their chests. Roughly half the students are restrained in their chairs: the students that were enrolled by their parents or sent here as punishment. A tall woman with professional clothes and long, wavy red hair walks out on stage and approaches a nasty looking machine.*

"Hello, students. Welcome to another year. I'm sure you'll enjoy your sexual training this semester, or at least get a lot out of it. As I'm sure most of you know, all students must have their Sexual Initiation Test on the first day of class to determine their curriculum. Your instructors will help guide you through this process, but lets have someone come up and serve as an example. Our volunteer will be randomly selected, of course."

The Head Mistress pushes a button on the machine and it activates, many restraints opening and several phallic devices moving into position.

"Now, who's going to show us how it's done? Hm?"

A petit girl with orange hair stands up immediately and shouts "ME!" Slightly embarrassed at her sudden out burst.

Name: Maria
Age 26
5'5
D cup breasts
125 lbs
Maria has a sexual drive that tends to drive her mad with the need for someone or something to bang. Regardless if its a dom boy, a sub boy, or even another girl, shes more then ready. And what a perfect opportunity. She enrolled very willingly.

The Head Mistress responds, sighing as if this isn't the first time Maria has done this sort of thing.
"Alright, Maria, come up here and let's get you strapped in."
Once she was on the stage, the Head Mistress pushed a button on a remote she had, just like all the instructors have. Maria's top responded, opening remotely and her breasts burst out into the open air. Simultaneously, her string panties retract revealing her nether regions to the whole school. All student uniforms are able to be retracted by the instructor's remotes.

Now that she is exposed, Maria is ready to use the machine. A bicycle seat sits on the front, a large, automated dildo pushing through its center and two mechanical cups hanging down in front to caress her breasts during the process.

Maria hops on, the dildo pushes into her pussy cleanly. Having experience with this before, the insertion is nothing to go crazy over. She attaches the cups and begins to peddle the bike.

The dildo begins to move in and out, more and more rapidly as she gets up to speed, the gentle sucking on her nipples growing more intense with time as well. Soon, she would not be able to contain her orgasms, with the whole school watching. The machine starts to take precise readings, preparing a curriculum for her to match her sexual prowess.

Maria jolts as her body fills with ecstasy. The start was nothing but the now that machine is at work she orgasms easily. Her pussy drips juice constantly, she grabs the cups and presses them further onto her.

Once Maria had came a few times, the machine gripped her hips and forcefully pushed her down as the dildo forced its way up against her, putting a great pressure against her cervix in an attempt to give her one massive final orgasm. Her curriculum was decided and the Head Mistress read it aloud to the whole school:
"-Advanced Fucking
-Oral Intercourse
-Tribadism Training
-Sensitivity Conditioning
Oh, and Gang Bang Training! Of course, those enrolled in this class have one third of their meals at the cafeteria replaced with cum. Lucky you!"

Maria looks at the Head Mistress. "Same as before?" She asks gasping for breath.

"If that's where you were assigned again, you clearly didn't pass your classes last semester, Maria. I hope you commit yourself to performing better and focus on your studies this year."
Before releasing her from the machine, the Head Mistress gives her tight ass a squeeze.
"...otherwise, maybe some corrective punishment is in order..."
