You don't believe them - you need them to show you they're being serious

"The things... the three of us used to do?", you ask.

"Yeah, you know what I mean", Hannah says throatily, her hand moving from brushing your crotch to your hand. "When you had us wrapped around your little finger." To punctuate that statement, she forms a circle with her index finger and thumb, and moves it onto your pinky in a way that can't be described as anything but lewd.

"I really don't", you say, backing up as Hannah approaches, only to stumble into Ashley. She holds you steady even as you step on her foot, and somehow manages to not complain or even sound like that hurt.

Okay, you need to cut the knot here. You're lost as fuck, and you all are just talking around the topic. "What the hell is going on, guys? I seriously think I'm either going crazy or that I lost my memories, because I definitely don't remember anything like this going on before last night. We never fucked! If this is a prank, cut it out, and if it isn't, tell me!"

Ashley had leaned in as she caught you a moment ago, breathing sexily on your ear, but now it sounds more like concern than anything else. "We're not pranking you at all, and you're not acting like you've gone crazy. What memories do you think you lost?"

"Well, I remember you two dating", you say, and watch as Hannah raises an eyebrow.

"But we are! Why would you think we're not?"

"You two have basically been hitting on me for the last few minutes! Why would I think you're dating, if that's what you act like?"

Ashley forms a word that sounds like "Ohhh", and as it brushes against your ear you shiver. Anticipation on the part of your body or nervousness on the part of your mind? "I think you've forgotten one specific thing, dude, and that's all. You're not acting different otherwise. Hannah and I are dating, but you're something more for us. If you wanted us to break up, we'd break up; if you wanted us to do each other right now, we would. And, of course, when you want to join us, you'll always be in charge." She pauses for a second, letting you take that in. "And I don't mean just in charge in the bedroom. I mean anywhere. Hannah and I want you to be happy more than we care about anything - about our relationship, about money, about our jobs. You want anything, and it's yours."

You don't get less tense. Apparently, you've forgotten something major, and your existential crisis isn't really fading.

But what are you going to do? Go to a mental hospital and get involuntarily committed? Get your brains scanned? It's not like MRI can detect specific memories that have changed or something, and Ashley's all but said that nothing except that memory seems like it's changed.

Apparently she can feel your tension, because Ashley lets go of you and gives you a little space, and Hannah backs up a bit after. "When I say we'll do anything for you, I mean it, but we're not going to **** you to do anything. If you want to see what we will do for you, though, if you want us to prove it - we'll show you, without you having to do anything at all."

Just play along, as much as you can without freaking out. Maybe your memory will come back. "Fine. Sure. If you want me to believe you when you tell me about something as ridiculous as wanting nothing more than to please me - if that's true, then show me."

You turn around in time to watch Ashley head back into the bedroom, and the other girl follows her soon after. Hannah gives you a small smile, almost shy, as if she wasn't just telling you how she'd be happy to fuck you.

The door shuts behind them, and you can hear them rummaging through something. They're talking loudly enough you can hear their voices, but not loudly enough to hear their words. Except for a few mumbles - "Nervous" and "slow".

After a bit, you hear Hannah whisper something, and then Ashley's voice. "We're ready! Come in!"

You open the door slowly.

Lying on the bed is Ashley, dressed in a sheer white dress. Lying on top of her, her smaller and skinnier frame wrapped in Ashley's embrace, is Hannah in black lingerie. The smaller girl is resting her head in the crook of Ashley's neck, but is otherwise completely still.

They're positioned so that when you enter the room, your crush can turn her head to you. "If you want us to show you, then we'll show you. We're both yours - not just to use, but to direct. So, if you want, then jump in any time, but otherwise -"

Hannah chimes in, her voice faint due to her head still being on her girlfriend's neck. "This show's for you. So, tell us - how do you want to see the two of us make love?"
