After half an hour of this, just as I was about to switch off the device, a voice that made my blood boil echoed from the recorder.
"Ah... professor, not here, people from the company will find out."
I quickly returned the playback speed to normal and cranked up the volume. As I continued to review the videos, I realized the recorder wasn't recording, so I didn't have to worry about it looping and leaving evidence.
"It's okay, this corner is so dark, and the windows are specially designed. They won't be able to see inside," came a voice from the shadows.
"But professor, it would be disastrous if your wife were to come down and discover us," a female voice responded anxiously.
A sudden tearing sound echoed through the air, followed by a series of intimate noises that would make anyone's cheeks burn with embarrassment.
