I would definitely allow for the blackmail route to evolve into something that gets Lisa interested in exploring other sides of sex instead of the ones we're seeing. There potential in turning Paul into someone that gets her to explore different venues of her sexuality adding more variety to the usual and common actors that are circulating her. Paul can help her explore more of herself in her home than just the outside and be able to get to the point where she gets tired and paul ends up getting kicked out of the tennis academy. remember paul is only there for a short period which could help in removing him for a time and returning later again in the future, as he's there for the summer. Time in the game hasn't really been talk about too much as the events could have taken over a period of a few weeks which gives the creator more time to develop and determine a set period of time.
