After taking a deep breath, Avril finally said, "Alright, let's do it."
"Huh?" you mumble, unsure of what exactly she was agreeing to.
"Let's swap, you and me."
"Are you sure?" you ask. While you were happy she was on board, you wanted to make sure you weren't pressuring her into something she didn't want to do. "You seemed pretty worried about it."
"Sure, but I do still want to see this in action, and if we do it this way, no one else is involved if something goes wrong."
"Alright, sounds good." You once again hold out the remote for Arvil to hold. "Grab onto this, and don't let go. You'll only be able to notice the changes if you're holding it."
"Or so the manual says," Avril mumbled to herself, cautiously taking hold of the remote. Clearly she still had a couple doubts about whether the remote would work.
"Ready?"
"Ready when you are." With no further hesitation, you press the button, and despite seemingly nothing happening, it immediately elicited a reaction from Avril. "What the-!?" Following Avril's gaze, you noticed a chapstick floating just next to her, frozen mid-air. She must have dropped it just before you pressed the button to test your earlier claims.
"See, I told you it could stop time."
"You definitely weren't lying about that," Avril replied, clearly astonished by what was happening before her. "And if it can really do that..."
"Then it can probably do the swapping part as well." You raise your free hand and point at Avril, cause a trio of holographic screens to appear before you, startling both you and Avril. One showed an image of yourself, another showed an image of Avril, and the last one, positioned between the others, showed a list of things that could be swapped. You flicked your finger along the list, watching as it scrolled further and further, revealing yet more options for things to swap. "That's... a lot of options," you mumble to yourself, spoiled for choice. It was clear the remote catered for more than just body parts. Clothes, name, job, even your entire life was an option. You were certainly spoiled for choice. "Any ideas?"
Avril seemed just as stunned by the myriad of options, watching the list scroll by through the back of the screen. "Uh, you can choose," she stated, clearly a little overwhelmed.
"Are you sure?"
"Uh, yeah, just pick something. Whatever you want, it's fine." She looked away from the screens, almost as if to keep the swap a secret from herself.
"Okay, if you say so." After scrolling back up towards the top, not wanting to get too far into the more obscure and nebulous options, you ultimately settle on a choice that would be pretty noticeable to the two of you, but would be easy enough to hide if anything went wrong and people could see the swaps or you were stuck like this. After selecting it, you notice a small change in the images, showing that they would act as a preview of the results of the change had you chosen something more obvious. Regardless, the one change was enough to be a test for now. "Confirm," you said aloud, activating the swap and causing the holographic screens to disappear.
Before the chapstick can even hit the ground, you hear Arvil let out a muffled shriek, clearly shocked but not wanting catch Maria's attention. She was looking down again, but as you followed her gaze, she was no longer looking at the chapstick, but rather at the small bulge, ever so slightly visible through the front of her skirt. In a similar but less visible manner, you could feel your own changes, your boxers being much emptier as your privates were now internal.
"Oh my god, it worked," Avril mumbled. "I have a..." Her hand paused its slow drift towards her crotch as she looked up at you. "Do you mind if I...?"
You gave a small shrug in return. "I mean, if this works like I think it does, that's yours now. Go right ahead."
"How you think it does?" Avril asked, before curiously prodding her new bulge with her finger. "Oh jeez."
"Well, the manual said that people wouldn't notice the swap unless they were holding the remote," you said, fetching your phone from your pocket, squirming a little as you attempted to get used to having your girlfriend's privates between your legs. "So if no one notices that anything has changed, then... Aha!"
"What?" Avril asked, walking over to you a bit awkwardly, clearly unsure of how she was supposed to walk with your junk dangling from her crotch. You showed her your phone, or rather the image you'd found on it. It was a photo from a time the two of you had gone to the beach together. Naturally, you were both wearing swimsuits, making it clear to see that Avril was packing a certain something in her bikini bottoms. "Whoa," she mumbled, staring at the picture.
"It's like we've always been like this," you explained. "People won't notice the swap, because they think you've always had-"
"Okay, you don't need to say it," Avril interjected, still a little overwhelmed by all this. "You know, you seem awfully calm about all this."
"I mean, this is weird for me too," you say, gently patting your now flat crotch. "I just knew what we'd be swapping so it wasn't a surprise for me."
"I guess that makes sense. So, um, what now?"
"Well, we could try out the remote some more. Try swapping a few other things. Maybe go out and find some new targets instead of just swapping with each other. Or if that's a bit too much for now, we could just hang out for a bit and try to get used to this."
You had deliberately left "just swap back" off of your list of suggestions. You'd just had your world turned upside down by a reality-bending remote that had given you your girlfriend's privates, you weren't exactly eager to go right back to normalcy. Thankfully, despite her awkwardness about the bulge in her panties, Avril didn't seem to be in a rush to get rid of it either. Whatever you ended up doing, it was clear your relationship with Avril was never going to be "normal" again.
