So anon, it appears that upon waking up one morning you have regressed back to being a shota somehow. The room you have woken up in is not your own and the door is locked. Suddenly the door unlocks and your oshi walks into the room, apparently the cause of your current situation. Regardless of whether or not they are a shotacon they seemed to have kidnapped you to make their personal sex slave for a week before they change you back and let you go.
Who is your oshi and how will they treat you? Will they take advantage of your small body to abuse and dominate you?
Will they spoil you for the week and make you wish it would never end?
Or will they be so submissive that you manage to dominate them the whole week despite being a shota?
