Millie moves forward

Millie's could still feel the taste of cum as she looked around. She was in a tunnel, clearly carved out by someone, or something, as she could still see the marks of pickaxes on the walls. It was nearly completely dark where she stood but as she looked ahead to where the tunnel made a turn she could see a light flicker. Millie stood still for a while, working up the courage to continue forward, and then took a deep breath, exhaled and then started walking down the tunnel. She could tell it sloped slightly down hill as she walked, not by much, but she did not like the thought of going gradually deeper.

Behind her she heard a scraping sound of stone scratching against stone and she turned to look what it was, and to her horror she realised that the door was closing behind her. She briefly thought about trying to run out through it, but the opening looked to narrow plus what would she do on the other side? She had to continue forwards and hope that she could find a way out.

Continuing to walk, Millie reached the point where the tunnel made a slight bend and where light was coming from. She slowed down, trying to stay in the shadows and see where the light was coming from. She strained her eyes to see, and saw that the light was actually moving on the walls. She moved closer to look, and saw that worms which appeared to glow in the dark were covering the walls of the tunnel, generating an orangy light which allowed her to see.

Cautiously she continued forwards staying close to one of the walls, she heard foot steps in the and stopped to listen. They were not coming from very far, but they sounded like they were moving away from here. Millie stood still and let the footsteps disappear in the distance until she started walking forwards again, almost tip toeing not to make a sound.

The tunnel seemed to widen as Millie continued forwards. It was getting colder also, and Millie was barefoot and only wearing a thin robe. Millie rubbed her hands together, trying to stay warm as she slowly tip-toed forwards.

Then, she heard a scraping sound behind her. Her heart started beating faster and she turned to look behind her but there was nothing. She moved towards the wall, keeping her back against it and then, looking backwards and forwards she slowly moved forwards. She heard the sound again, and this time she saw a shadow move out of view as she turned to look.

Millie felt her heart racing and how sweat started running down her forehead. Who, or what, was stalking her through this tunnel? She gazed towards where the shadow had disappeared but saw nothing, standing still she waited for her breath to slow down, then she started running down the tunnel as fast as she could.
