"Oh God, you're not starting this 'I'm the greatest hypnotist in the world' thing again, are you?" Muff Diver said, as she pulled her face away from between Ponygirl's thighs. "We've all heard it before, Mistress. Nobody here believes a word of it."
Mistress leaned forward, both out of interest and to give Assmuncher better access to the valley between her spread butt-cheeks. "Oh, come on," she said. "What makes it so difficult to believe? You know I'm charismatic, don't you?"
Muff Diver pumped three fingers in and out of Ponygirl's cunt so that she could keep stimulating her pussy without losing her ability to contribute to the conversation. "Of course I do, Mistress. You're sex on legs, everyone here knows that. But that's not hypnotic in and of itself. That's just..." She shrugged as expressively as she could with one hand jammed into Ponygirl's slit and the other fingering her own. "That's just who you are."
"So what makes someone a hypnotist, then?" Mistress asked, her lips curling into an amused smile. "Since you've suddenly become such an expert."
"I dunno," Muff Diver said, feeling her pussy clench in satisfaction around her own fingers as she watched the tassles on Ponygirl's buttplug sway and jiggle from the other girl's surging orgasm. "Maybe, um, actually hypnotizing someone? You keep telling us you're the best hypnotist ever, but none of us have ever actually seen you do anything."
Mistress arched her back slightly, Assmuncher's ministrations obviously having an effect on her. "Maybe I hypnotized you, then hypnotized you to forget I hypnotized you."
Fuckswing spoke up from across the room. "But that's a theory that's impossible to either prove or disprove," she said, contorting her neck slightly in an effort to see everyone else right way up. "The net result would be absolutely the same whether you'd never hypnotized us, or hypnotized us to believe that we were never hypnotized. It's an untestable theory." Muff Diver grinned. It was obvious that Fuckswing was a science major when she wasn't hog-tied and dangling upside-down from the ceiling.
"Mmph!" Ponygirl said around her ball-gag. None of them bothered to remove it.
"It's not entirely untestable," Slutbunny said as she walked into the common room, shedding her clothes as she did so. "Sorry, I heard you as I was getting in." She pulled off her panties and skirt in one smooth gesture. "But it's true. There are ways to test it. Just because we couldn't remember being hypnotized ourselves, doesn't mean that we wouldn't notice something unusual about one another." She folded her clothes neatly and set them in the cubbyhole next to the door, then began putting on her strap-on harness.
"Mmmm," Muff Diver said, before realizing she'd started licking Ponygirl's slit again without thinking about it. She made a conscious effort to pull her face away long enough to say, "And none of us do. We're all of us the same people we've always been, and ymmmph mmm mmmblm..." She dragged her mouth away one last time. "And we know it."
"That just shows how good of a hypnotist I am," Mistress responded. "I've made the delusion perfectly seamless, so that every one of your programmed commands seems perfectly natural. You don't even think about how obedient you're being, because it just seems totally normal to you. All of my commands find that core of deep, fulfilling ecstasy within your subconscious, even the command to forget that you're following a command. It's just too hot, too sexy not to obey me."
