You decide to work on your stomach and arm muscles, and so head to the rowing machine. After 20 minutes or so, you've gotten quite sweaty.
You lean back and shut your eyes for a few moments, and before you know it, you've fallen asleep!
An hour or so later, someone sits on you! You try to push them off, but you can't. You've turned into the seat of the rowing machine itself! Who
has placed their ass on your face?
