JBD-176 - The fragile assassin seeking revenge, Kanon Takizawa

The structure uses the elevator to transition between scenes. Constantly tying and untying her might be a bit redundant, but the whipping while suspended and the intense, deep thrusting during their encounter were powerful and satisfying.

The actress isn't utilized at all. They just tie her up. It's boring. The person doing the tying is responsible for the progression, but there seems to be zero creativity here. When there are multiple people tying her up, no one is in control.
