Capturing the Boss to use as bait.

The men picked their target very carefully.

They found the Boss on the floor and went after her first.
Why?

Simple- you can use her phone and e-mail to lure the rest to where you needed them to be.
You learn allot in Robber School- if you pay attention.

They found her Office and pushed the door open softly.

She got up to see what was going on...and they grabbed her!

Alexis was caught off-guard and was easy prey.

With the door closed, the pair were now in a sound-proof environment.
Yes, it also pays to read the Building Schematics!

"We won't hurt you," the older one explained.
"We just want what is in the safe," the other one concluded, "Do you have the combination?"
"...no, I don't."
"Who does?"
"B-barbara."
"Is she here," the older one pressed.
"She'll be back in...in an hour or two," Alexis explained.
"Alright. Make this easy and you won't be tied up naked with your Co-Workers. Understand?"

Alexis nodded and didn't put up any more of a fight as they tied her up.

The rope pressed tight around her stomach, pressing her big tits against the fabric of her white blouse.
The gag concluded her bondage...for now.

They perused through her files and picked out the targets to take out next.
