@Kllick She's a bit too strong headed. She might accept getting touched with the item that render his hand imperceptible since she has no choice, but probably wouldn't accept going further just because she gets aroused. To her, he's still her "student that she needs to protect", but that's starting to change a little.
I don’t get what the end goal of all this is. The main character has sex with his teacher and classmates, which allows him to search a dungeon to collect items which make it easier for him to have sex with others?
@Trigger111 the only reason I check this manga every now and then is to check if someone stab this imbecile in the dick. Nothing yet. I really hope there's some form of karma in this story.
