The butt hovering over his head belonged to his daughter Euphemia li Britannia. Charles tried to scream out STOPPPPP, NNNNNNOOOOO don..." but was flattened by his daughters royal bum. luckily for him, Euphemia noticed an itch in her butt and stood up unknowingly trapping the emperor in between her buttcheeks as she stood up.

She plucked the nuisance form her ass and brought him around to her face and said "Daddy? is that you? why are you shrunk and why were you in between my asscheeks you pervert?" the emperor responds very angrily "Euphemioa you idiot you sat on me and dont you dare try to call me a pervert as for my shrinkage i have no idea how it happened."

Euphy says " oh sorry about that dad but your chair did look very comfy. i didnt mean to sit on you but as for you shrinking it was probably one of my sisters to try to get revenge on you for taking away all there luxuries." charles looked astonished and worried when she said this .

"But dont worry daddy im not going to hurt you but i do need a new servant and right now it doesnt look like your going to be arguing too much today hehehe . my feet and lower back are killing me but maybe i can think of something else you can do besides that? After all i should be really creative with you at such a helpless and small size. oh and if you dont want to be my servant ill gladly give you to one of your other daughters to entertain them. "
