ZUKO-096 A super-cute family is seriously too erotic, so they have a baby

You have come to Tokyo to take the entrance exam. Staying at a relative's house that I don't like. The reason why I'm not good at it is because the four sisters in the Kokon family are extremely serious. When they find out that you are taking an entrance exam, they are in a lot of trouble, and of course they start cheering you on with all their might. If it's cold, I warm up naked, come to the bath to wash my body, and concentrate.
