She makes a deal.

Mallory's Stepfather eventually comes by again- about 20 minutes later- and she speaks up, risking his wrath.

"Maybe...maybe we could make it up to you with a different kind of show."
"We? So you and Jenni huh?"
"Y...yes."
"Alright. I know just the thing."

Mallory gulps...and panics when he leaves without untying her...

A bit later, the duo are reunited, both naked (Jenni's panties were cut off) and now bound differently.
He's placed a large, glass table top on the ground and they are both on it.

He's tying Mallory into a hogtie, soon to do the same to Jenni.

"The goal is simple- knock the other girl off of the circle," he explains, "Put on a good show now...or else."

They both gulp at the thought.

They do their best, but the glass has little slack and is a bit sticky.

Even so, Jenni- channeling some inner anger about how her helping did so much to hurt her- manages to push Mallory off.

"That was good, but I see the problem. You both stuck too much.
I have just the thing for this."

He leaves and returns with a large bottle of baby oil.
He wets his hand and enjoys every lingering second as he rubs the naked duo down.

They both know better than to complain at this, simply waiting for the game to resume.

The next round begins...
The pair are unaware that he is filming this btw.

Mallory doesn't want to lose and makes sure to give him something to entertain him.

She has to win...

Jenni is also in no hurry to lose and be punished herself.
