There is always a lingering question that every mistress must ask herself: what to do with your slave when leaving the house. The only logical answer being: tie them up to keep them out of trouble. This is what Hinako does here as she puts her sub in a satin rest sack and ties him up with rope. She puts him in the closet, gives him a piss bottle to keep himself company and says sayonara as she leaves him for the evening.
