You definitely soften her up.

You take the blond bitch back to your Lair.
You set up a nice new Room to punish newbies in. It is full of weird Medical Supplies- just to freak them.

You bring Carissa in there, tie her up with tape and strap her down to a chair. You play with her a bit...

After you are done playing with her for a bit, you check your text messages. You see one from the Dominatrix that Carissa belongs to.

As you can see, they are having fun with Dee...

You text them back with a few suggestions of what Dee 'likes.'

'They'll have fun with her,' you think.

You return to Carissa and tie her up in a new position...

She's tied to the wall with her legs spread and can't move a muscle. With her body propped up like this on a stool, she's in the right position for your man to fuck her with a dildo...

Nearby, you have your own fun with Donna.

You need to occasionally remind her that she belongs to you- just in case.

A day tied to a wooden object and **** to cum at your bidding should do the trick...

As a bonus, Carissa sees it all play out...
