download a hypno file, wear panties, go into a public toilet stall and listen to it while masturbating. you cannot stop masturbating, so if you cum, you have to keep going until the hypno file ends, not only that you have to wipe off all the cum into the panties and leave it there. come back a hour later and if its still there, wear it home.
if you survive masturbating all the way, you may cum with no consequence
