MIST-148 — The Invisible Woman, Aki Sasaki

Aki Sasaki's invisible world is visualized! When she arrives at work, her co-workers don't even notice her presence! At first, she calls out to them, wondering if they're ignoring her, but no one responds. So she shows off her underwear to a male co-worker to get his attention, but there's still no reaction. However, she notices that the male co-worker's penis is erect! What action does Aki Sasaki take after that?
