Risk the bridge

You creep slowly across the bridge, which creaks alarmingly under your weight. Peering down, you see the horde of snail girls staring back up at you, silently. Step by creaking step, you nervously make your way over to the far side, breathing a sigh of relief as your foot press down on the reassuringly solid rock. You cheekily wave goodbye to the snail girls in the pit and make your way onwards.

After a short stretch of rough rock tunnel, you come to a wider chamber. The wall on your left is rough rock, two narrow cavern entrances leading onwards to more caves. The right hand wall is natural rock too, but carved into a fresco showing several beautiful naked women, dancing around a rather phallic looking pole. The wall ahead of you is made of stone bricks, and in the very centre of it is a heavy old oak door in a grand arched frame.

The door has no visible lock or handle, but in the middle of it is a brass head, beautifully made. It is the face of a woman, her eyes hungry and playful, her mouth open wide and, well... rather suggestively. You can't help but notice that it is mounted at waist height...

Looking up, you see words carved across the stonework at the top of the arch - "FEED ME TO PASS".

You look at the beautiful brass face, gleaming under the light of your torch, and rub your chin. Nah, this has got to be a trick... right?
