More fucking and some negative reinforcement.

The next day, the woman is placed into the hands of one of your Trainers.

This man works simple- tie up and fuck the poor women! He's there to make them yearn for anything else, while also learning how to be more submissive.

After a day of this, you ask her if she wants to be taken to another man.
She shakes her head.

You planned for this, leaving her in the all-too-evil hands of some women who are also **** Trainers.

They are not any nicer.

The trio punish her severely, using all sorts of evil devices.

They don't have cocks, but they punish her pussy (and ass, a little) all the same.
They have no mercy.

She is embarrassed when she has to cum several times.
She is mortified when she has to make them cum.
She is saddened by how part of her enjoys this.
She wants it all to end.

Finally, she is returned to you the next day.

She's in light bondage, but doesn't struggle.

"Do you want more training?"
She shakes her head 'no.'
"Then show me that you're ready to be a real ****."

She approaches you submissively and gets on her knees.

"Nice, but it isn't my cock that you need to suck."

The man who hired you enters and presents his cock to her.
A mix of shock, shame, anger, fear and acceptance goes across her face.
