The Subway Fister.

There's a sex-crazed maniac on the loose in Berlin's U-Bahn: unsuspecting travellers are being used and abused during their underground journey. Mercilessly, the victims are fucked and fisted on their public benches. Who wouldn't want a season ticket? Even on the tracks nobody is safe; the U-Bahn Fister throws a bootsbag from behind over his victims' heads before dragging them into the catacombs. Here the delinquents have to endure his cock and fists over and over again, complete with a bucket load of Subway-Piss.
