Confined by the couch cushions and incapacitated by the scratch mitts you feel unable to resist and meekly allow Daphne to pull the diaper up your legs and into place.
"Good Girl Ella" Aunty Jane smiles at you "Now we can make you all pretty"
Daphne reappears with a bundle of clothes and begins to dress you. Little ruffled bobby socks decorated with a pink ribbon are slid onto your feet. Then a pair of ruffled white panties, trimmed with matching pink ribbon, are pulled up over your diaper. Finally Daphne holds up a pink frou-frou dress all ruffles, layers and ribbons. She holds it over your head and carefully guides your hands through the sleeves. Once it is over your head she pulls you out of the couch and makes you kneel whilst she pulls the zipper up into place, clicks a small padlock through the loops in the back of the neck, and fusses with the fabric fluffing it out so that it hangs properly.
"Aw Daphne, Ella looks so cute in her pretty pink dress. You said you wanted a little sister to play with and now you have one"
"Yes Mistress, she is very pretty thank you so much for letting me have her"
You realize that the pretty Ella they are talking about is you. Apparently you are Daphne's new little sister and this is just the beginning of a very strange adventure.
