I don't understand why people want to make this kid-friendly.
By the looks of it, this game is obviously going to have a teen rating, so having the Shit text, the blue balls and dirty language isnt going to go.
If kids play it, it's their fault, I don't think its the games fault.
There are mods for this though, There are mods that remove the blue balls for example, the Senpai text you might have to change it yourself as well as the Shit text. I dunno if Moms outfit is also a problem, but I dont know what to do about that, sorry.
