They become Fetish Models

The quartet don't know why they are naked.

They don't mind...but they don't remember agreeing to this.
They also don't know why it was necessary.

Tracey, Rosa, Amanda and Priscilla agreed to the stipulations.
Why question it?

They sign the Contracts and get dressed.

He calls each of them separately to set up Photo/Video Shoots.

Rosa works first, doing a Shoot where a 'Security Guard' ties and dominates her.

She'd never even kissed a girl before that day.
She'd never even thought about it.

Never been tied up, even after a curious boyfriend suggested it once (or three times).

Now she was on her knees being fucked with a strap-on.

Even so, this feels right.
