"Oof!" Having not really been watching where you were going, you accidentally bump into something. You were looking down after the bump, and from what you could see from the clothes, you had just bumped into your girlfriend, Zelda. Still, something felt a bit off.
"Oh, sorry Link. I wasn't watching where I was going." You try not to react, but the voice you had just heard was your own. Looking up, you see yourself, or your body at least, wearing Zelda's clothes. You had thought you had looked ridiculous wearing Peach's clothes, but you hadn't actually had to look at yourself head on then. Now you could see clearly what you, or at least your body, looked like, and it certainly wasn't pretty.
Trying to keep calm, you reply, "Don't worry about it. I wasn't watching either." You do your best not to freak out as Zelda's voice comes out of your mouth, although even now you can feel that your mouth was different, like your facial structure had been rearranged. But not just that, you could tell your entire body had been changed into Zelda's but if you started examining your body in front of her, she'd know something was up.
"Well, I've got somewhere I need to be. I'll see you tonight." She give you a wink, which honestly looks a little weird coming from your body, before walking off down the hallway. You quickly look over your body so you can decide whether you want to swap back nor not before she disappears. The obvious thing when you look down is the pair of breasts sticking out from under Wii Fit Trainer's tank top. Below that you have Zelda's slender arms, her thin waist moving into her larger hips (larger than yours at least), all the way down to her thin legs and dainty feet. You could also feel Zelda's long brown hair on your head, pulled into a ponytail by Wii Fit Trainer's hair-tie. The outfit at least looked better on you now, but you weren't sure that was a good thing if it meant accidentally stealing your girlfriend's body.
As you ready the remote, you mind thinks back to what Zelda said. "I'll see you tonight." With a few couples entering the tournament (and from how you had seen Little Mac around the Wii Fit Trainer, the possibility of new ones being formed while at the tournament), Master Hand had set up a couples room that people could rent out to spend a night together with their special someone, and tonight you and Zelda would be using it. This causes you to stall the swapping back. Sure, it felt a little wrong to be stealing your girlfriend's body, and it felt very different to your old body (you weren't sure if it was a good different or a bad different yet), but now you were curious. Maybe you could keep Zelda's body for tonight just to feel what it would be like. Still, you suppose if you wanted to, you could give Zelda's body back and borrow someone else's for tonight. Although even with your curiosity, you weren't sure you liked having a female body, especially one with so much less muscle mass than your old body. As Zelda is about to round the corner and leave your sight, you decide to...
