Subway portal to another dimension

[Clairic]

Looking for a story where a woman find a room attached to a subway tunnel...they are about to seal up the room or tunnel... in that room some how sure gets tied up and then sucked into another dimension where she will be sexually tortured and be a slave for ever and never die or get old. The room eventually gets sealed up there no chance of her ever being saved.

Thanks in advance
