Behind the Pyramid's Door

I ran over to the pyramid and felt around for any sort of opening to the door. After pressing around, I found a button that opened up the door. I quickly ducked inside as I heard the guards come in.

"I thought I heard someone go in here!"

"Check around! Don't let them escape!"

I leaned with my back against the door, listening to the sounds going on outside. Footsteps clamored around trying to find me, but none of them looked inside of the pyramid. I heard them begin to retreat when I heard one of them in front of the pyramid exhibit.

"Hey, dude, check out this exhibit."

"The Amazing Sex Pyramid? Press the button for a demonstration?"

Before I knew what was happening, my hands were suddenly bound with something metallic, then my ankles. "Wha- hey!" I was flung around as the pyramid opened up, bringing me right out in front of the guards.

"LONG AGO, THE ANCIENT EGYPTIANS HAD MANY SEX RITUALS THAT COULD BE PERFORMED. WE AREN'T ENTIRELY SURE HOW THEY MANAGED TO CREATE SUCH DEVICES. THE LEADING THEORY IS ALIENS. SEXY ALIENS."

A robotic pre-recording began to play from an unknown speaker.

"LET US BEGIN A DEMONSTRATION OF HOW THESE DEVICES WOULD WORK, THANKS TO ONE OF OUR SEX VOLUNTEERS."

"Hey, isn't that Agent Roxxie?" one of the guards said as he pointed to me.

"Oh yeah, it totally is. I didn't know she was a sex volunteer."

"A sex what?" I said, trying to free myself, but my arms and legs were suddenly pulled in different directions, holding me spread eagle in front of this crowd.

"CLOTHING DETECTED. REMOVING."

A metal tendril came around and lifted up my shirt, exposing my tits. It then moved down and removed my pants and panties, completely exposing me.

"WE BELIEVE THAT THESE DEVICES WOULD BE USED TO PLEASURE SACRIFICES SO THEIR FINAL MOMENTS WOULD BE PEACEFUL AND BLISSFUL. OF COURSE, WE HAVE NO WAY TO KNOW AND ARE ABSOLUTELY NOT JUST SPECULATING. FOR DEMONSTRATION PURPOSES, WE WILL NOT BE EXECUTING OUR VOLUNTEERS. WE LOVE OUR VOLUNETEERS AND SHOW THEM PLENTY OF LOVE."

"Waitwaitwait! There's some mistaaaaaaake!" The next thing I knew, the metal tendril began to thrust itself inside of my pussy rapidly at speeds only a machine could achieve. Two suction cup ends came around and attached themselves to my breasts, sucking on them and tugging on them. "Get me out of her- MPHPH!" Another tendril came around and entered into my mouth, facefucking me in front of the crowd.

The DOOM henchmen were cheering loudly at the scene, two of them were even stroking themselves.

I tried my best to wiggle free, but the pleasure was too much. It was too intense. Even though they were metal, they felt warm and soft like flesh. I could even feel them emitting a delicious lubricant to make it smoother. The rapid speed of them was sending waves of pleasure far faster than what I was used to and I quickly came. But that didn't stop the machine. It kept pounding away at my holes, orgasm after orgasm it caused me. The henchmen just cheered wildly at the show, all of them now masturbating at the scene.

"FOR THE SAKE OF OUR VOLUNTEERS THAT WE LOVE SO MUCH, WE MUST END THE DEMONSTRATION HERE FOR THEIR SAKE. THANK YOU FOR WATCHING!"

"Aww man, that was so hot!"

"We're still gonna capture her, right?"

"Oh totally."

I groaned in pleasure as I was brought back inside the pyramid and dropped down on the floor. I could barely feel my legs. I could hear the henchmen beginning to approach the door. I looked down at the CHYOA device on my wrist and figured that now was as good as time as any to try it.
