Lanyard → Deep and Wide Cleavage

I exchange 'Lanyard' for 'Deep and Wide Cleavage' and watch as Penrose's camera shifts to be directly in front of her. The room re-organizes around her while her black skirt turns white and her lanyard vanishes. In its wake, her shirt unbuttons one at a time from the top down until it's almost entirely open but for the last few just buttons above her skirt. She's not wearing a bra, but her shirt is still just barely covering her nipples and holding her breasts in place... somehow.

Her expression remains perfectly composed and professional with only the faintest hint of a blush on her cheeks.

Alright: this was a good start. Now what?
