Ectoplasm party!

The girls were carried down into what could only be described as a dungeon. A huge vaulted stone room with manacles and chains attached to the dripping granite walls, lit by flickering torches that cast an orange light into the gloom. In the middle of the room was a pool, as long and wide as any swimming pool, filled not with water but a roiling misty greenish-white substance that neither of the girls liked the look of.

At the far end of the room was a huge computer console, covered with blinking lights, and in front of the console sat Miss Trickett. She was a tall, exotic, coffee-skinned, raven-haired woman in a tight black silk cheongsam, and she was monitoring the house through a dozen or so computer screens.

She pressed a few buttons on the computer, and the surface of the pool, greenish-white, somehow both misty and slimy at the same time, roiled beneath Bonnie. Inside, solid shapes writhed over each other, coalescing from the ooze and dissolving back into formlessness. Hands! And... other things.

"You know what ectoplasm is, right?" said Trickett, "It's ghost cum."

She sat back and watched with interest as dozens of spectral hands emerged from the pool, grabbing at the girls, tugging and teasing and stripping them out of their bras and panties. Once the girls were naked, they were dragged down into the pool, struggling all the way. It felt exactly like being dunked into a giant vat of cum. Only much, much cummier.

Bonnie's mouth was pried open by grasping fingers. She swallowed cum, gulped, and swallowed more. Of course, it was ghost cum, and vanished as soon as it got into her system, so there was no limit to how much she could swallow. And she could breathe fine, even submerged in all the cum.

A ghost penis was probing at her pussy. It slipped inside her, filling her up, and almost immediately started pulsing as it came. Another, smaller ghost penis slipped into her ass, and started to cum as well. Finally, a big cock slid into her mouth. She tried to bite it, but she couldn't hurt the cock, since it was a ghost.

Hands were all over her, stroking her breasts, caressing her nipples, fondling her bottom. Her whole world was just touch, hot warm hands and cum. She really wished it didn't make her feel so incredibly good, but ghost cum was a natural aphrodisiac, of course.

Once Trickett had judged they'd had enough cum, she summoned the girls out of the pool again and deposited them on the floor of the dungeon. She made them lick all the ghost cum off each other's bodies, then look directly into her video camera and masturbate to orgasm, side by side, while they both confessed what dirty horny little cumsluts they were. Then, she used the computer to upload the video to every single porn site, under Susie and Bonnie's full real names, and emailed the link to everyone in their Facebook and Instagram contacts.

Starring in a porno would have no negative effects of any kind on the girls' lives, of course, because of carnival magic. But that didn't mean it wasn't very humiliating for both girls!

Once they were done, ghost hands simply carried them back up into the Haunted House and left them in a random room, to find their own way out. Susie and Bonnie scampered through the creaking halls, side by side, naked and squirming, painfully aware that the whole world was going to know them as dirty porno girls and masturbating cumsluts for the rest of time.

At last they found a door onto the outside world, and ran through it, into the busy streets of the carnival. Where everyone saw them naked.
