She does what he asks, hoping for leniency.

Starla considers this.

'What choice do I have? Suffer for 20 seconds or be stuck out here for the rest of the day?'

The man knew that this would probably work.

A friend of his loves to punish ladies in the water and has had great success with the old 'hogtied in the water' game.
He remembers seeing the video he was sent of him with a lady.

He turns his attention back to Starla.

"Well, are you going to do it? You have ten seconds to decide."
"Okay- okay! I'll...do it."

She lowers her face down a bit.
He gave her enough slack to get her face fully under- what a coincidence!

She keeps going, finally submerging her face.

She counts in her head.
20 seconds feels like an eternity.

She pulls herself up at 21 and gasps for air.

"Good enough. I'll get you in a few moments."

He prepared her next position...and took extra time walking back.

He stood her up and tied her instead with her hands in front of her.

As they neared a waterfall, he tied one loop to each ankle- just not together.
He led her through the shallow water and made her sit on the rocks, the water coming down at her back.

'This is not much better!'
