Ocellus meets with Twilight after school, her teacher is just a little bit more than what she appears to be.

After School Detention

The bell rang throughout the school, signalling to one and all that classes were over and that it was finally time to go back home. That was true for all the students, except for one. Ocellus.

Not because she lived at the on school dorms. Well she did, but that wasn’t why she wasn’t leaving. Packing her things into her saddle bags, she stood up from her desk and began trotting the wrong way down the halls, making lots of annoyed and confused faces of the ponies she bumped into.

She didn’t care, she had somewhere important to be. As long as she didn’t bump into anyone she knew, she’d be all fine.

“Yo Ocellus, where’re you going!?”

There goes that plan.

Ocellus looked around to see Sandbar looking at her while waving his hoof in the air. As much as she wanted to, she couldn’t exactly pretend to have not noticed him. That’d just be too suspicious. So she crossed the hall to go and hopefully not sell herself out.

“Hey Sandbar, what’s up?” She asked, putting on the most convincing smile she could.

“What’s up?” Sandbar asked rhetorically, “ I should be asking you that, classes are over for the day.”

Luckily, Ocellus had prepared “I’ve got an after school detention with Twilight, I’m not free for another hour” A technically true statement, now as long as he didn’t-

“Daamn, bad girl Occy. What did you do to land you in Twilights bad books”

She caught me masturbating in class, Ocellus shrugged “Not a clue, she just told me to meet her after school.” Now that was a full lie, but she hoped that’d stop any further pressing

Sandbar nodded, “Fair enough, I shouldn’t keep you waiting then. See ya once you’re done”

Ocellus smiled and returned on to her path deeper into the school. The more she travelled, the less and less ponies she saw. Before long, she was walking on her own down the halls. Not that she’d be alone for long, as one more right turn put her in front of the door she’d been waiting for.

A plain wooden door with the privacy blinds fully closed and a simple “Do Not Disturb” sign hanging off of the rounded door knob. She didn’t try to turn the handle, instead just knocking her hoof against the door in a two-tapped rhythm. Before she could even put her hoof back down, the lock clicked open and the door swung itself open with purple magic.

With one last look both ways down the hall, Ocellus stepped into the seemingly normal classroom. It had desks for students, a desk for a teacher, a blackboard and posters all around. All things that were present in all other rooms in the school. The only difference? A small box, and a purple mare sat next to it.

“Welcome Ocellus, on time as usual” Twilight praised

The changeling flicked her magic to remove her saddle bags, leaving them next to the door where she came in. “If there’s anything you taught me Twilight, it’s how to be on time”

Twilight raised an eyebrow, “And how to put on a show, apparently”

Ocellus blushed while moving to stand at attention in front of the desk, “Did you like it?” She asked with a nervous smile.

The mare sighed, “You have to be more careful Occy, you might’ve gotten caught if I hadn’t stepped in.”

“I didn’t hear a no?”

Now it was Twilight’s turn to blush, “Okay, you got me there. It was certainly a pleasant sight to be surprised by.” She shook her head, “Just don’t do it again, you could get in all kinds of trouble.”

By heart Ocellus replied, “Yes mistress Twilight”

A perverse smile grew on her face, “You’re eager to get started then?”

“I’ve been waiting all week for this,” Ocellus propped her hooves up on the desk, “Please Twi~”

The alicorn’s horn flared with magic, the sound of a metal box snapping open filled the room. Ocellus’s eyes locked onto what her teacher lifted out, a singular collar.

It wasn’t too fancy of a collar, a purple faux-leather rim with small metal studs lining the outside. The only thing that made it different from all others was the tag on the front, a simple but effective word denoted what she was. “Slut”

The changeling sat in wait, her muzzle up in the air, waiting for the press of the collar against her.

And waited.

She let out a groan as the familiar weight wouldn’t come.

As if on cue, she felt the leather wrap push around her snugly. Clamping together around the back to form a fit that was perfectly tight. Lowering her head again, she looked towards her now more-than-teacher.

“Thank you Mistress..” She knew better than to complain now

Twilight nodded, “You’re welcome Slut, I’m always glad to put you where you belong.”

Hearing her play name always sent butterflies through her, “How may your slut service you today, Mistress?” Twilight always had a plan, hopefully that included letting her-

Her mistress’ voice cut through the inner monologue, “I believe my Slut requires some inspection today, she was given a rather important mission. That is, if she wasn’t too dumb to forget it, that is”

She could never have forgotten, turning around Ocellus flagged up her tail. “Your slut edged herself daily just for you Mistress~” It’d been a difficult task, that was for sure, she’d even done it in the hall once when Smolder refused to leave their shared dorms.

A wave of magic brushed along her labia, causing her to let out a needy moan as it slowly circled around her hole. Never pressing in, just feeling her twitch and writhe.

After what felt like an eternity, the magic faded away, her mistress giving a small hum of appreciation. “Someone’s living up to their name~” She teased, “Such a needy Slut, so desperate for someone to just take her.”

Ocellus was barely able to keep her hooves straight, her magic kept flaring as she fought the instinct to touch herself. Barely able to stop herself each time.

Twilight stood up from her desk, slowly walking towards her submissive, not a word leaving her mouth.

The Slut looked over her shoulder to see Twilight towering over her. But what interested her more was what was underneath. A singular purple dildo hung hungrily from her mistress’ groin. She admired the faux-shaft, a wolven based cock with a tapered tip and a large knot. A small bead of liquid dripped off the tip, what Ocellus imagined was her mentor’s animalistic precum.

She pressed her flank as high as it’d go, showing off her fertile holes to her beastly mate. Twilight loomed above her, and she let out a sigh knowing what, and hopefully who, would be coming. But then she felt the large mare above her stop, inches away from feeling her dominant’s shaft.

“M-mistress?” The Slut asked out, her voice quivering with lust

Ocellus felt the mare above her wrap her legs tighter around her, she gulped around her tight collar.

“Yes Slut? What is it?” She could feel the smirk on her Mistress’ face, even without seeing it she knew what she needed to do.

“Please~ Your slut really needs you to use her fuckholes” she begged, “She really needs the pleasure that only her Mistress can provide.”

She felt the tip of the cock press against her tail hole, not her favourite but she’d make do for sure. “Hmm, but which hole dear Slut? This one?”

Twilight lowered her hips, pressing her shaft against the burning hot labia of her student, “Or maybe you’d like this one?”

Ocellus pressed her body up against the larger pony, “My holes are all yours to use Mistress, take the one you want~”

She felt the canine shaft slowly push into her pussy, she was relieved until she heard her Mistress say, “All of your holes?” What does she mean by th-

Sharp pain rang through her body as twilight pushed her not into her vagina, but rather the tight hole next to it. Ocellus let out a pained cry as she shouted “Orange! Orange!”

Instantly, as if a switch was flipped, Twilight pulled back and fully out of her. She barely had time to think before she was in front of her, probing her with all the questions. “I’m so sorry Ocellus, I didn’t realise that’d hurt. It did hurt right? I’m so-”

She was cut off by a chitinous hoof pressing against her lips, “Twi it’s fine, I just wasn’t ready for it. You did kinda just ram it in there.”

A sheepish look ran over Twilight’s face as she rubbed the back of her neck. “Sorry, again. I thought that because you’re a changeling and all… Sorry. I won’t do it again, promise.”

Ocellus leaned forward to give a small peck of a kiss, “It’s not a ‘no’, twi. Just a ‘not today’.” She stood up and turned to flag her tail. “Besides don’t you have a hole to claim, Mistress~?”

A smirk on her lips, Twilight answered, “I do think I do, Slut. “

Once again, the familiar weight of the alicorn settled in above her. Brushing her carapice against the soft fur, wishing that she wouldn’t have to endure a whole extra round of teasing. A wish that came true with the feeling of the rubber shaft press against her pussy. Without the teasing, and certainly without the pain, Twilight slowly pushed her shaft deeper into her sub’s vagina.

A canine cock was probably Ocellus’s favourite, the perfect mixture of a piercing tip and changing width pushing all of her buttons in just the right way. And not to forget-

*pop*

The knot~

Ocellus moaned out as the wolven knot stretched her wide open. She clenched as hard as she could as Twilight began pulling back, trying desperately to keep her inside.

But with another wet pop the knot fell out, taking most of the shaft with it. The emptiness wasn’t for long though, as another thrust filled her up perfectly again.

She moaned upwards, hugging her body as tight as she could against her stud. The faux-cock began pounding her relentlessly, forcing spikes of pleasure each time the knot stretched her out. And with how long it’d been for her, she felt like a powder keg on the verge of exploding.

Ocellus tried to lock eyes with the alicorn towering above her, “M-mistress, can I-i..” she began to beg

Without interrupting her thrusts, Twilight craned her neck down to deliver a short peck to her loyal sub. “Not yet my little Slut~”

“W-what?” She could hardly believe what she heard. It was taking almost all of her effort to not cum on the spot, and now she needed to hold it longer?

Twilight giggled softly, “You heard me, you’re not allowed to cum yet.”

Ocellus twitched subconsciously, “Y-yes Mistress, not yet.” She could take it, all she had to do was not focus on the dildo spearing her open. How every ridge felt as it rubbed against her sensitive vagina, and how the knot split her open with every thrust. How she could imagine it twitching and filling her up with wolven cum. How ea-

She was pulled out of her spiral as she felt a set of warm lips wrap around her own. Opening her eyes that she didn’t even remember closing, she saw Twilight’s eyes stare deep into her. She couldn’t help but moan into the kiss. So close to finishing, but so far away.

Slowly breaking the kiss, leaving a small strand of saliva connecting them, Twilight whispered, “Are you ready to cum now?”

Ocellus was too enraptured by pleasure to do anything but nod

“Then cum, my little Slut”

And just like that, she let herself fall deep over the edge. She moaned uncontrollably as her vagina twitched in a spastic rhythm. Each twitch sending a clear load of marecum flying down onto the floor. The euphoric high didn’t last forever, as the twitching slowed and Ocellus slowly regained her faculties.

When she properly came back to, her face was pressed against the floor, her hips only supported by the cock knotted inside her.

Slowly, she picked herself up as Twilight pulled herself out of her student. Before she could even say a word, she felt a click at the back of her neck. The collar, that she’d half forgotten she was even wearing, flew away in purple magic.

Ocellus sat down on the floor, checking first that she wasn’t sitting on anything wet, looking up at the alicorn who was levitating a towel out from behind the desk. “Thanks Twi”

The mare smiled and looked down towards her, “You’re very welcome Occy.” The smile quickly morphed into more of a grimace, “And, uh, sorry about that again.”

This time it was Ocellus’s turn to giggle, “Twi it’s fine. That’s literally what safewords are for, aren’t they?”

Twilight dropped the dampened towel back behind the desk, “I still hurt you though..” she sat down in front of her student.

Ocellus shook her head, “Tell you what Twi, I’ll let you make it up to me”

“Make it up to you?” She echoed

With a smirk, Ocellus nodded, “Let me top you for once, I bet you’re still really worked up after all~”

Twilight bit her lip, clearly into the idea but.., “I don’t think you’re tall enough for that Occy, I’m an alicorn remember?”

A wave of green fire washed over Ocellus. For a changeling like her, a transformation like this would be child’s play. And seeing Twilight’s jaw drop, she knew she’d hit the nail on the head.

A white stallion now stood as Twilight’s equal, his blue mane flowing majestically. “What do you think Twily, think this’ll work?”

Twilight’s tail began to rise, as a hunger grew in her eyes. “This’ll work just great BBBFF, it’ll work just great~”

A kinky mare for a kinky student, a match made in lewd heaven
