There's a huge amount of different content and sex in the game: vaginal sex, anal sex, oral sex, hand job, foot job, MF, FF, MM, MFF, MMF, BDSM...
But don't worry if any of those tags are a turn off - the game will never force you into anything you don't want to experience. For example if you don't care to see FF or MM you won't (because to do so you need to actively stay on that route).
This also means there's a lot of content to discover (as someone mentioned you can have sex with the teacher - yes, but there're other girls you can have sex with as well) - the game works best in multiple playthroughs.
We're working hard on Episode 5 which has a huge amount of images so it is taking somewhat longer. But we're getting closer and closer. Follow the news on our Patreon!
