Unlock the door

You decide to try using the key you found in the safe to unlock the strange door in the living room. As you push the key into the hole, you feel a chill going down your spine. You're about to find out what your captor is hiding. You open the door, and...

What you find is worse than you'd imagined. A full-blown sex dungeon. All kind of depraved devices littered the room. It looked like something out of a movie. Advanced mechanisms that seemed built for **** and control stretched far and wide. The walls are covered by advanced monitors and cameras. And in the corner of the room, bouncing up and down on what appeared to be some sort of intensely vibrating dildo, you find a woman, softly sobbing to herself behind a muffling face mask that covers her entire face. That must be your friend. Your first instinct is to help, but... Maybe there's another way? She did look quite beautiful, after all... Maybe she could stay like this a little longer.
