No, leave it quite open

From Create Your Own Story

As you sit down, with your panties at your ankles, the foreman appears in the hallway.

He appreciates your brazen display and smiles. "Can I come in?"

You simply smile back at him.

"I need to take a piss too, you know," he says.

You do:

• Quickly finish and ask if you can watch him pee
• Stand up to kiss him, piss still streaming down your legs
• Without breaking his gaze, tell him "Go ahead, I don't mind" without making a move away from the toilet
• Kneel on all fours with your ass in the air, still with your panties down, and tell him to use you as his toilet
