She is converted into Moon's sexpet

Moon/Mizuki/Selene is into pet play, so she hypnotizes Lillie to make her her pet and sex ****, making her wear Alolan Vulpix cosplay permanently, a white leotard with white vulpix ears and 9 fluffy buttplug tails. Lillie obeys every order, in bed and outside of bed, and can talk to answer to Moon her commands, but most of the time she only makes Vulpix sounds and eats from a poke-bowl on the floor of the kitchen.
