The wrong Kamui (private)
 

Ryuko matoi woke up from a twelve hour sleep. It was not a willing sleep though. She was put to sleep by the suit she had on. A full body suit with snaps at the crotch, and bonds that kept her knees and ellbows together. A gag was in her mouth, that kept it open for anything, weather it be dildo's, tubes, bottles, or her new master cumming into her. She was wearing a massive diaper, which made it impossible to move. She opened her eyes to see her surroundings.

Satsuki came into the room "Ah. Good morning baby sister" she cooed and pulled back Ryukos diaper to see if it already needed a change "Did you sleep well, my beloved?"

She moaned something, not able to speak propperly, and struggled. She was not wet yet, but that would change

"Aww you're diapee is still dry. Who's a smart little baby? You are! Yes you are!" Satsuki cooed and tickled Ryukos sides "Well, I guess big sister has to feed you now..." she began taking her top off

She groans and tries her best to move away, but the living suit began to restrain her more tightly, so she was unable to move

Satsuki took Ryukos gag out but quickly replaced it with one of her ample naked breasts "Drink up, then we can have some big girl fun"

She angrily bit down on satsuki's breast

Satsuki winced slightly but didn't react otherwise "I said suck, unless you want to be my diaper wearing baby sister forever"

She hissed as she began to drink

"There's a good lass" Satsuki praised smiling
