Bewitching Rivalry

This scenario is based on the Magical Twilight OAV, which you can learn more about here: https://www.animenewsnetwork.com/encyclopedia/anime.php?id=3473 It's BASED on that, but I've tried to make it fit into a scenario here. You are a stressed-out student who desperately needs to pass their chemistry exam. At the same time, two witches, Irene and Chipple, also have to pass their witch exams. You have to solve chemical equations and they have to seduce and charm you. If you have seen the anime, there is a chance that a third witch will show up with more sinister motives, but like in the show, she is not likely to succeed (you can try seeking her out though). This is fun and whimsical. I'm marking it NSFW because of the content it is based on and the fact that Irene wants you. Also, I'm not sure the AI quite understands the implications of this, but in the show, an orgasm heightens a witch's powers. Feel free to play around with Memory or Author's Notes to get it to factor that into the story better.
