She heard you and is surprised but eager

"Who's there?" You hear in your post-orgasmic stupor, and you lazily turn your gaze towards the sound. A moment later Alex bursts through the door, her tense and cautious posture slightly undermined by her weapon of choice being a pillow.

"Oh, hey Alex," you reply, unsure just why she's on edge. Sure, you probably shouldn't be openly masturbating in the kitchen, but you doubt she'd mind that much. You've caught her doing the same and you were both pretty casual about it. The perks of having a roommate as slutty as you!

"Who... Who are you?" Alex asked, her voice a little suspicious. Why wouldn't she recognise you?

"Uh, your roommate Yay Yay? Like, obviously?" You reply, a little suspicious of her being suspicious.

Any distrust melted away from Alex's expression, along with her confusion, and she quietly muttered, "Oh, so this is what it's like from this side."

It takes a moment to sink in, but you realise just what she means by that. You had to deal with Alex suddenly turning into an Asian bombshell overnight and... wait no, you've been gal pals with Alex for years and...

"I... wasn't Yay Yay yesterday was I?" You hesitantly say, still trying to piece together what happened.

"No, I'm fairly sure that my fuckbuddy/boyfriend wasn't an Asian slut like me," Alex jokingly replied.

"Hey, I can still be your fuckbuddy!" You immediately reply, indignant. You know from the false memories you have of being gal pals with Alex that she's bisexual like you and while you weren't intimate with each other in those memories, she has already been intimate with your previous (male?) self.

Sure, you may have other things to worry about, like the fact you apparently used to be a guy (weird), but a chance to get closer with Alex couldn't hurt, right?

"I mean that does sound tempting," Alex replied, "But we probably should get an idea of what happened to you and if we can reverse it. I'm fairly sure the old you would be concerned, and as hot as you are now, I do still want dick."
