She begins to, tie her up.

Katherine seems to stir as you finish emptying yourself into her unaware mouth. Perhaps a rough throat fucking does that sometimes.

You take action quickly though. Sabrina is still tied and blindfolded on the couch and you quickly run and grab another blindfold and more rope. You proceed to yank the blindfold over Katherine's eyes. At this point she is starting to stir. You turn her around and hear her mumble a "huh?" in groggy confusion. The sleeping pills keep her disoriented and she doesn’t understand why she is being moved around and why she can't see. You grab both her arms and start typing the rope around her.

At this point she seems to realize something is wrong, but it’s too late and you’ve finished tying her arms behind her back. She opens her mouth to scream and you stuff a gag in. Katherine tries kicking her legs next but you catch them and **** them together, tying them as well. She continues to struggle for several minutes but tires out, realizing her position is hopeless. You see a tear roll down her cheek but her expression remains angry. Katherine’s got a lot of fight in her and most definitely would have been tougher to ****, but fortunately you’ve got her sister to use against her as well as the just recently recorded footage including all three of you.
