They think it's a fair treatment

"Teach her also 'thank you' next time and I may pay you... Are robot being paid?"
"There is no need ma'am, I'm programmed to do my best to make the patient follow the house rules"
"Rules? What rules?"
"Master showed me the house rules on the dusty white board"
"Oh, I know what she's talking about" and Michael run to take the board to show it to her mom.
"Oh god, how many memories. I wrote these thing to scare you guys when you were children. But nobody has ever followed these, me neither. I'm surprised you are following rules like 'Go to bed when you are told or receive 22 spanks' now, at 23 years old"
"I'm not following those useless rules, and now we have to return the metal garbage to the hospital"
"Oh no, you will follow them, every single rule because Eve stay. I liked how you behaved when I entered the house, I hope to see that often from now on"
"What? No mom, you-. . . You cannot do this to me!"
"That volume is a little too high, Eve can you tell me what is the rule number 9?"
"Screaming is not allowed, 18 spanks for every infringement"
Emma place quickly both hands on her mouth, she has been spanked enough for the day, and she looks like she's starting to cry again, rushing to her bedroom before someone could notice.
"By the way, Eve, will you spank also Michael when he doesn't respect the rules?"
"No, master has complete freedom to act as he want"
"It looks like you are a lucky boy, and she likes you, she even call you master "
"Yeah, that's a long story...."
Michael has thought to the hypothesi for a moment and the idea don't suit him. He surely wasn't jealous of his sister's fate.

In the mean time Emma is finally alone, in her room. She's got tears in her eyes and a hand on her bum feeling the hot temperature coming from it.
She has been humiliated and molested like never before and her family seems don't care about her. She feels alone, in case like these usually Michelle is the only one that can help her feeling better.
