She finally gives up the fight!

He teases her pussy a bit, pleasuring her.
She's confused by this, but know that he's up to something.

Right as things get good, he pushes her face down in the Riverbed again!

He holds her there until she gets close and then pulls her back up...

Sarge stops short of letting her cum.

"Good Slaves get rewarded. Are you one?"
"No, Sergeant."

There's less command in her voice this time.

"You will be," he replies, grabbing a stick.

He holds her head up by the chin and smacks her feet with the reed...

He now combines the two punishments.

He smacks her feet and down to her reddening ass.
He fingers her pussy.
He presses her down in the water and then up once he's ready to deny her.

On the second cycle, she's about to break...

He holds her down and fingers her.
She gets close.

He pulls her up and smacks her feet.

"Do you submit?"
"Yes, Sergeant!"

"Good slut! Of course- you don't get to cum now.
You have to earn that privilege.
I'll get you out in a few minutes," he says walking off with a chuckle.

The Scene fades out and now we see her next punishment...
