Wash her face

Anthony had tons of ideas about how he could torment her and pleasure himself using her body, but he didn't want to go too fast, he wanted to appreciate every second of this, and not go straight to the conclusion.

He leaves her for what seemed like no more than 2 minutes to go a different different of which she could hear the door squealing when he opened it, only adding to the creepiness of this place and her situation. Various other sounds follow, the main thing she could tell apart was that of a water bucket being filled. She had an idea of what was to follow at this point, tho she hoped that maybe she was wrong.

Several times during their inline conversations they had talked about waterboarding as a **** method and they even joked about trying it on each other, as a challenge, if they ever meet, they had seen people in Youtube doing it to their consenting friends and such. But this was a whole another ordeal, she was tied up, she was away from anyone who could possibly rescue her, there was nothing to do to protect herself and she had to count on his mercy and empathy, which he probably had a lack of or else she wouldn't be there in the first place. It was terrifying but she knew she had to calm down as much as possible if she wanted to stand any chance to survive this, or minimize her suffering as much as she could.

She hears his footsteps getting closer when he comes back with exactly what she guessed, a towel in his hands her confirmation about what she thought he was going to do to her.

She barely has the time to take a deep breath when the towel suddenly lands on her face blocking her vision, and immediately the water starts falling right on top of her mouth and nose. Quickly her nostrils end up filled with water and her body's reflexes make her attempt to get up repeatedly only to be defeated by her bonds, she twitched pointlessly, as the urge to inhale air was getting harder and harder to resist. Her head turned right and left as to avoid some of the water and attempt to inhale some air, which Anthony only picked on by the time the first water bucket was empty.

She can hear him leave the room again with the empty container, the towel still on her face lets her know he's coming back with more. From the room where he went back to refill the water bucket, Anthony could still hear her panting coughing and blowing her nose. It was basically a room turned into a bathroom for basic needs in the dungeon, it had that old "squatting toilets" system that consisted of a hole in the ground, and a tap in the wall. He made sure to let the water slowly fill the container so she could hear it as a way to let the tension and anxiety build up inside of her, just to make everything a bit worse.
