Investigate doorway

Up further in the path you see a giant bronze doorway built into the stone. Deciding it would be a good place to look for the Mountain King you traverse the steps to it. The doors to wherever this leads is very decorated. Gold and silver run through the frame and diagrams depicting events are scattered about it. The pictures show automated men worshipping a figure. You have heard the stories about machines in caves and ancient ruins but you shook them off as crazy tales to scare away people from trying to explore dangerous locations. As you look at another diagram it appears to depict women being pleasured by these automatons, hopefully these machines are fake or broken by now.

The door is heavy and takes great strength and effort to push it open. You are now in a lobby decorated with the same design on the door, torches light the room and there is another door on the opposite side of you. As you push on the next door you realise it's locked and hear a whirring noise begin. The locked door has activated a contraption. Raising your sword you prepare for anything. In the middle of the room the floor separates revealing a chair rising to fill the new gap. The mechanical noises stop and you investigate the chair. It is metal with inscription written on its side, there is also a dildo pointing up on the seat. The inscription reads “To enter the mechanical fortress you must offer payment in fluid.” Seeing where this is going you give out a sigh and decide to head back than try whatever the chair is wanting.

The door that originally let you in is now locked and you are trapped in this single room. “Of course it is. The chair seems to be the only way out now unless I want to starve to ****.” With that declaration of defeat you begin to remove your armour looking at that bronze ribbed seven inch dildo which will be inside you soon. Now completely naked you perch your vagina over the dildo, building up the confidence to insert the vile contraption.

You begin to lower onto it. You feel it part your folds, its cold surface sending goosebumps all-over your skin. A moan escapes your lips as the tip is finally in your pussy. As more inches slide in you feel its ridges rubbing against your walls, your hands clench at the feeling. Finally all of it is in your pussy and you wait for the door to open. After a couple of seconds more mechanical noises are coming from the room. Metal straps suddenly coil around your legs and arms binding them to the chair. “What the…” you scream before straps restrict your head and a tube is inserted in your mouth. A strange milky substance begins to pour into your throat straight to your stomach.

As if it couldn't get worse, the dildo retracts from your pussy before ramming back in repeatedly, being powered by hydraulics. “Mmmm, mmmm, mmmm!” Is all you can give it as the dildo fucks you relentlessly. The intense pain you felt to begin with is now pleasure as it keeps fucking you even through your orgasm. After several more climaxes you feel a strange sensation in your chest. Peering down you see your tits have grown at least two cup sizes bigger and your nipples are like pencil erasers. The sensation however keeps increasing as your body receives the fucking of a lifetime. Milk begins to spray out of your nipples and soak into the floor. The outburst of milk causing another cascade of orgasms, making your eyes roll back into your skull from the overload of pleasure. You barely worry about your new lactating breasts as you begin to lose consciousness from the nonstop dildo that has caused you to orgasm multiple times, causing your thighs to be soaked in cum and your brain to lose function. This chair could fuck you to **** if you can't escape.
