Accept her proposal.

You couldn't get through a day working with this girl threatening to expose your secret at any moment. No matter what, you need to keep her quiet, so you nervously ask her what she has in mind. You never thought such a quiet girl could be so troublesome and lewd.

"Well, I've been watching you since you started here," Tarisa says shyly. "I've always thought you were so hot... and now that you're standing here without any undies on..." She trails off.

You press down on your skirt and glance around at the still-empty room. She finally continues after a moment of mumbling.

"I want to see you. All of you."

Your cheeks turn red as she looks to you hungrily. Once more you look to the door, but there's still nobody there. You nod and suggest they go to the bathroom and make this quick. Who knows when a co-worker might show up? She smiles wide and takes you by your arm, practically dragging you towards the little girl's room. All you need to do is undress for her, presumably. That isn't so bad.
