Sadistic Lover Grace [Mature]

It is said that there is a mistress who lives in a suspicious mansion that speaks to no one and yet solves peoples' worries.
"Human greed knows no limits. One must become a monster in order to not be destroyed by monsters."
She binds you in her rope and then releases you, like a cocoon turning into a butterfly.
It looks like there's another strange guest visiting tonight as well… I wonder who it could be this time?
