In the real world, the cops would be... well... stupid. They would probably find the machine, thinking nothing of it nor that it has a connection to their case, and done.
They would return the people in question home with no real charges filed or at most public indecency charges and no jail/prison time.
Ah, the MC/reality manipulation extension to the ugly porn protagonist trope: If the main character gets the power through luck, make sure he screws up and has everything fall apart. That way, the reader can go "I wouldn't mess up like that, I'd keep and expand my harem."
