Test the jewel with Bianca.

Testing

Diane can wait another day for her gift. Right now, you're too enraptured by Bianca, who in turn is too enraptured by the glimmering pink stone dangling between your fingers. You need to take her some place private, where you can test the limits and possibilities of such a miraculous rock.

"Bianca, is there anyone else back there with you? In the office?"
"No," she answers. Looks like the coast is clear. You direct her to let you in through the side door. Once inside, you take her into the back room, all the time leading her with the pendant, like the not-so-proverbial donkey led by the not-so-proverbial carrot.

Inside, you find a large rectangular table surrounded by chairs. You can imagine staff meetings and interviews taking place here.

After Bianca shuts the door-- at your behest, of course-- you have her sit down, so that you might conduct your own interviews...

You continue to watch Bianca follow the bejeweled item. "Do you like me, Bianca?"
"Nooo," she says dreamily.
This pisses you off a bit. "No, you DO like me. Do you like me?"
"Yessss," she says.
"You will do whatever I say."
"Whatever you say."
"Kneel!"
Bianca slides off her chair and falls slowly to her knees.
"Bark like a bitch!"
"Arf! Arf!"
"Massage your pussy though your clothes."
Her hand drops down and she starts rubbing herself.
"Hmmm," you think to yourself. "I could really teach this bitch a lesson about being mean to freshman!"
