She has to hop for you.

You make sure to tie her ankles together and then point her towards the door.

"Go. Forward."
You give her a spank.

She tries to walk, taking baby steps.
"I don't have all day. Hop for me, busty bunny."
Another spank.

She sighs into her gag and begins to hop.
What a lovely sight.

Natasha needs help, which you give by grabbing one of her tits to point her the right way.
If and when she drifts, a little tug straightens her out.

Your other slave- still bound and horny- sees her enter.
She won't give away the game and acts scared, calling out through her gag.

Natasha can hear this.
'Oh no- he was telling the truth! He has two of us here!'

You grab a chair and push/set Natasha in it.

You go over to the other woman- Natalia- and tell her that you're going to fuck her.
You tell her to not give away her joy too much- part of the game.
She nods.

You return to Natasha and remove her blindfold.

"You're going to watch what happens to her. If you look away, I will punish you. Understood."
Natasha nods.

You go to the bed...
