Nearly there!

The next day, you bring back the other Trainer that started with her.
He ties her in a new position and oils up her ass, enjoying the feel of it and how much it embarrasses her.

To make matters worse, he has a long dildo on a stick and starts to fuck her with it!

He fucks her hard and fast with it.
She loves it.
She hates it.
She hates herself for loving it!

As she gets close, she breaks a little bit...

"Please let me cum- don't stop! Don't stop!"

He looks at you.
You shake your head.
He stops.

You both leave, keeping the dildo stuck inside of her.

An hour later, you two go again.
She gets close.
Denied.

Twice more this happens.
Each time she is told to leave the dildo in and not let it drop.
She does so.

As you start her fifth time, she finally breaks...

"Please stop- I'm your ****! Let me cum- please!!!!"
"Who is your Master?"
"You are!"
"Let's prove it. Move her to Position 6 in Room #3."

You both untie her enough to move her and retie in an adjacent room.

She is tied with one leg up and with her hands tightly behind her back.

"Tell me what you want, ****!"
"Fuck me, Master. Make me cum- please!!!"

You enter her freshly-fucked pussy and give her the first taste of the real thing in quite a while.
You grab her bound wrists for leverage and fuck her until she begs to cum...

"Please let me cum, Master!"
"On one condition- I need information on your friends and organization. I want to make them my Slaves too!"
"Anything but that!"
"The intel or you never cum again- ever, ****!"
