You glanced down at your schedule, and saw....
Potions.
This could be...interesting, if nothing else. It was a class that was constantly fresh, as the majority of the time was spent learning how to create all sorts of concoctions. Some, like the Auget Celeritas draught, had gotten you out of a few sticky situations. Others, like the Immobilis brew, had been the cause of many sticky situations.
You were torn away from your thoughts by the teacher, instructing the students to follow her along to the classroom, which was located right by the front of the dungeon. While this may have been a more dangerous location than a typical lab, it was also the most convenient, as many valuable potion ingredients could be found within the seemingly infinite passageways and atriums the comprised the dungeon.
With a swish of her whip-like tail in front of, your thoughts about the dungeon, school planning, and general safety were instead turned towards your instructor.
Ms Nemean Leo. If you were the prudish type, you could easily claim that her attire was hardly fit for teaching. Her shorts only covered about half of her prodigious rear end, and her plush breasts were tightly pressed into what must have been a tank-top at some point, but was now closer to a bra. There were a few reasons why you decided not to speak up about it. One, you were not a prude. Two, while her outfit may not have been suitable for teaching, it was perfectly fine for moving quickly, as one would have to do when around a dungeon. And three, given her temper, it certainly wouldn't end well.
The third reason was also the main reason.
The well-built woman was famous for her short fuse and general hot-headedness. She was by no means dumb, far from it, but if something set her off she would undoubtedly act first and think about the consequences later. Of course there were countless rumours about the things she'd done, each more unrealistic than the last, but you'd rather not find out where fact and fiction diverged.
As the class shuffled in, you took a seat at your much smaller desk, which had been positioned atop Cece's desk at your request. You figured she would be the least likely to take advantage of you, at least intentionally. The classroom itself was very much a dungeon-esque style. Stone walls and flooring, wooden shelves lined with ingredients, bubbling brews and mysterious vials in abundance. Apparently it used to be a part of the dungeon, but was cleared out and retrofitted. Given the potential for damage in the class, it was easy to see why something sturdy was needed.
"Okay class, open your textbooks to page 34, so we can begin today's lesson!"
A strong yet friendly voice rang out from the head of the class, the voice of Ms Leo. Given your small size, you didn't actually have a potions book of your own (with the textbooks being specifically designed for the much larger students), however it was easy enough to read along with your centauress classmate.
"28...31...ah, 34!" The very equine in questioned mumbled, flipping through pages as you gripped your desk tightly to avoid being blown away. Thankfully the hot-headed teacher had the foresight to bolt your desk down, exactly for this reason. You glanced down at the page and saw something that made your heart sink.
Auget Flatus.
Or, more simply put: Increase Gas.
This was not going to be an easy lesson.
Some of the less mature among your cohort giggled, having already figured out what they were about to make. Cece was not one of them, although that may be because her grasp of Latin was tenuous at best. Mia, on the other hand...she knew exactly what was going on, and how she was going to use it to her advantage.
"Now class, shut your gobs and eyes on me!"
Ms Leo called, commanding the room with her casual tone and powerful aura. Nobody wanted to get on her bad side, after all.
"I'm sure you've noticed already, but today we'll be making a simple mix, Auget Flatus! If you don't screw it up, it should look like this!"
The grand lion-esque woman displayed a vial filled with a dark green liquid, before popping the cork and taking a small swig, much to the surprise of some of the students. Others, specifically your minotaur friend, were already planning to exploit what was about to happen.
A rumble.
The whole class held their breath.
A growl.
Ms Leo bent slightly forwards.
And then...nothing. Wait, nothing?
"It doesn't work instantaneously, duh!" The teacher laughed at the collective confusion of the class. "It takes about 5 or so minutes to travel through your system and get absorbed where it needs to be. But we're not spending 5 minutes staring at my ass, so get to work!"
The class started getting to work, and the typical classroom chatter started up again as students began moving around the dank room, acquiring the materials they needed. You, on the other hand, were trying to figure out if you could make it through an almost two hour long class without breathing.
A few minutes later, the class had entirely forgotten about the display that the instructor had put on. Well, almost forgotten. One student hadn't stopped thinking about it. Mia. And her plan was about to be set in motion.
"Miss, can you come help me with this?"
She asked innocently, from her desk besides yours. The educator strolled over, and leaned over to see where the bovine brunette was stuck. This, unbeknownst to her, put her wide butt directly in your face. Her thin tail culminated in a strange, fluffy, pom-pom like structure, which swung above your head, casting a shadow on the oversized (for you, at least) textbook.
You looked up, to see if Cece had noticed, but she wasn't there, having gone to gather ingredients off of the shelves. Nobody was going to save you. And that's when it happened.
A gurgle.
You held your breath, bracing yourself on the table.
A growl.
Ms Leo bent over even more, bringing her almost bare ass right up to your face.
And then....
PPPPPPPPRRRRRRrrrrnnnNNTTTTTTT
BBBBBBRRRRRMMMMMPPPPP
PLP....PLP....PLLLLLLLP
A gust of foul winds rocketed out of her rear end, directly at you. And it reeked to high heaven. This was from that potion? And she'd barely drank any of it! The teacher sighed with relief, and winked at her student. As far as she knew, the teen was the only witness to her little outburst. Mia laughed, both at the gassy rump, and the unfortunate student who was forced to experience it. Thankfully, nobody else noticed your humiliation, too caught up in their own conversations and potions to pay attention.
Still reeling from the lingering stench as the teacher sashayed away, off to help some more students, something dawned on you. That wasn't it. You were about to have to deal with a dozen or so giant girls under the effects of that potion.
About half an hour later, your fears came true. By this point, everyone had finished their respective concoctions, and were now just waiting for the fireworks to begin. A mix of nervousness, anticipation, and in some cases excitement filled the room. And that was when it happened.
Prt
A tiny burst of gas made itself known, emanating from the ass of the lamia in the front row.
BROooNT
A rebuttal, made by none other than your lycanthropic step-sister a few rows behind.
PPPPPPPPPFFFFFFFFFFRRRRRRRRRTTTTTTtttt
The biggest blast so far, courtesy of the one who started it all, Ms Leo herself. That was the cue for everyone to start letting go, with the teacher laughing at the proceeding toots the blared out from everyone in the class.
You did nothing, save for cover your nose tighly. It barely helped, of course, as the classroom soon filled up with the stench of a dozen gassy monster girls. And then she got in on the action. A mass of minotaur ass-flesh presented itself to you, and its owner looked over her shoulder, down at both you and Cece.
"Hey girl, pull my finger!" She laughed, extending a hand down towards the half-horse woman. She was smart enough to stand up and trot around to the front of the mischievous woman. She was not smart enough to remember where you were. And so she rolled her eyes, knowing she'd have to just listen to her friend or get pestered the whole day about it, and pulled her finger.
BBBbbbbbrrrroooOOOOOOooowwwwwrrrrRRrrPPPRRRRRRRBBbbbbrRRRRpppPPPTTtttt
A bovine butt blast hit you dead on, sending you flying. But where did you land?
The Teacher's Chair:
The title says it all. And with about an hour left in class, mostly discussing the theory and principle behind the gas-inducting potion, you would be at the mercy of her butt unless she noticed you. And even if she did, she may not be too kind on you if she thinks you aimed to perv on her.
Step-Sister Saviour:
You're sent flying, but thankfully have a nice, soft landing....somewhere on your sister! Be that in her hair or in between her chest. Or, god forbid, on her ass, which you already know from living with her as a dangerous weapon.
