Millie opens the door

Millie looked at the object in front of her, and while it was a part of the stone door, it was soft to the touch, feeling like human flesh when she touched it. She moved closer to it, and it reacted to her breathing on it, twitching and growing larger. Millie ran her fingers along both sides of it, and it grew harder still, pointing towards her. Millie moved closer to it, smelling it, and it smelled just like the rock around it. Then, working up a bit of courage, she licked the tip of it, and it grew even larger, now almost a foot long.

Millie shifted backwards, stared at it as it twitched in front of her, swallowed hard and then opened her mouth and moved forward taking the tip of the cock in her mouth. She just held it like that, feeling it twitch as she sucked on it. It tasted like a rock, yet was now hard but still soft. Millie placed both hands on the shaft, and started to jerk it, twisting her hands and bobbing her head up and down the shaft. She felt it growing in her mouth, not wider, but longer, the head of the cock probing its way deeper into her mouth, searching its way down her throat.

Millie thought that she would gag, but the cock secreted some sort of lubrication, and slipped down her throat without gagging her. She let go of her hands and pushed her head forwards, effortlessly getting the entirety of the footlong cock down her throat. She kept going until her nose touched the wall of the door, then she just held still, amazed at her ability to deepthroat a cock this size.

Millie moved her head backwards, feeling the cock slide up through her throat, then moved her head forwards again, the cock filling her throat completely but she was able to breathe through her nose. She started to move her tongue against the bottom of the shaft, tickling it. She felt the cock jump in her mouth and the sensation continued all the way down her throat. She slid the cock out of her mouth, looking at it in its erect majesty, covered in her saliva and then gave it a long slow lick from the bottom of the shaft to the top, gave it another look, then engulfed it again with her mouth, just sucking on the head for a while, then taking it down her throat again.

Millie felt a tingling sensation as the cock rubbed against her lips. It was now well lubricated by her saliva and moved smoothly in her mouth. She adjusted the way she was sitting to get into a better angle and then started to move her head up and down on the cock rapidly. She felt the cock starting to twitch, tickling her throat. Millie increased the speed she was bobbing her head up and down and then she felt the cock make a move like it was pumping and the second after she felt warm, sticky liquid shooting down her throat and into her stomach.

Millie held the cock still in her mouth as it twitched and emptied its contents into her throat. She counted four thick blasts of cum, each released with a spasm of the cock, followed by little trickles of cum as the cock stopped twitching. Millie moved her head back, the cock came out of her throat and she held the head in her mouth giving it one long suck to get the last of the cum out. It tasted salty, Millie thought as she swallowed it.

Then, with the cock going soft in her mouth she heard the sound of rocks moving and realised the door was opening. Millie stood up, leaned down to give the cock a parting kiss, and then walked through the door into the darkness behind it.
