Young teen girl starts exploring her sexuality and soon discovers that the more sexual fluids she absorbs the smarter she becomes...but the increase in intelligence slowly starts to wear off if not renewed within a certain period of time. The more sexual fluids her body absorbs, the higher her intelligence ramps up. Peak intelligence (with no additional fluids absorbed) lasts for around 3 days then slowly starts to decrease back to normal levels over the course of a week or so. Being a young teen, it is initially difficult to find the time and opportunities to get a consistent source of sexual fluids so she experiences a lot of rollercoastering of her intelligence. But this eventually leads her to discover the timing limits of her gift which allows her to develops plans for the future to minimize the rollercoastering effects. Good thing she enjoys sex! lol
