To Take the tutors test you first have to go to the Bench in the park at like Day and sit there when the icon is available, there's a cutscene where you meet an older woman named Nancy who will offer to show you her breast for 5 dollars, pay her the five dollars and the MC will go on about how her breasts look disgusting but you will have to do this until you get Self Control, afterwards you can watch Alice or whatever shower without losing your cum tank, the next morning if you have a full cum tank and 10 in Study or what not, talk to Alice and there should be a Tutor Test option, if I'm wrong then sorry I deleted the game 3 days ago. The Dev of the game dropped a Walkthrough image in the comments, it's hard to see so if you can download the image.
