Trying find a one off story from way back that's been coming back to mind recently.
Starts with the teacher (I think it was a female substitute teacher) teaching a classroom of teen mothers. The class starts semi-normally, but the teacher uses either a drug or pheromones to start messing with the girls in the class. First she makes them turn in their panties, which I think she puts in a pot for some reason. She teaches them how its normal and good to be sexy and slutty. She has them demonstrate random sexual acts on themselves/one another and I think she even brings in some random students from the hall or other classes to participate as well. I think at the end of the day all of the girls in the class were given some of the formula or pheromones to take with them. Anyone within a certain distance of them would begin to feel the effects of the drug and succumb to them.
One of the main points of view was from a girl in the class that didn't have a kid herself, she was just there to support her twin sister. At the end of the class most of the girls were told to practice what they'd learned, this particular girl was given a different assignment, something about cleaning all the dirty panties at home with her tongue until she could recognize everyone's flavor. I think there were further chapters, one brought in some manner of horse sex, teaching the girls how nutritious horse cum was and I think the teacher had the valedictorian collecting the horse cum to share with the class she'd brought to the farm for a field trip.
The teacher I think had a partner in crime, a man, that was at a different school. The only thing I remember of his chapter(s) was that it started on a school bus with two girls arguing. One was embarrassed about the things he'd been teaching them/that they were going to do on the field trip. I think she had to drink something spiked with the drug/pheromones and she forced the girl she'd been fighting with to take some too by kissing her or something.
Sorry that the description is all over the place, just a couple vivid scenes stand out and I can't for the life of me piece enough together on my own to find it. Any help would be appreciated, I've tried every variation of the search and I just can't seem to find it.
