Elly wakes up on the couch. She remembers what's happened last time she fights against Elizabeth. Last one, covered her face with a chloro cloth and put her to sleep.
Elly find the chloroform over the table, so she waits hidden behind the wall, the return of her rival Elizabeth. She grabs her from behind and covers her mouth and nose with the chloro cloth. She keeps it until Elizabeth passes out.
Elizabeth is made in bondage, tied with ropes and gagged with a duct tape. Elly forces her to smell her stinky feet, covered with pantyhose. Then she smothers her with the facesitting technique, until Elizabeth passes out again.
Elly goes away. She has just completed the task, ordered by her boss.
