You gulp and hit dial. You hold the phone to your ear with both hands. The dial tone rings. Your heart feels as if its going to explode out of your chest.
Click.
"Hello?"
Your own voice comes out from the speaker. You can't help but be stunned by this bizarre situation. You hesitate with the phone in your hand.
"Karen, you there?"
You freeze up completely. Is this the power of the pendent? This... is more than a swap is it?
"Kaaaareeeen..."
"B-big bro?"
You stammer out the words tentatively. It's quite an amount to take in.
"Hey, are you okay? You don't sound so great."
"I... I was just, err, wondering where you were. It's gotten pretty late."
"What, you were feeling worried? Don't worry about your big brother, I'm on my way just fine."
"That's good, I guess..."
"Anyway, I'll be home soon, so could you prep the bathtub for me?"
"Alright."
"Thanks sis. See ya."
Click.
You sit down on the bed. Seems you've not just swapped bodies with your little sister, you've also become her. A bit dazed, you lie down on your back, your legs dangling off the side. After a while, your breathing slows, and you calm down. You also take note of your previous actions as well, such as your lack of difficulty in accessing Karen's phone, and your own sudden shift in emotional reaction. Getting up, you hurriedly replace the pendent around your neck. For protection, you think, you'd want to keep it as close to you as possible.
You sigh.
Well, as long as you are Karen, you should probably be a good little sister and prepare the bath. With some trouble due to the fact that you now have a new weight on your chest and your wider hips that make you swing slightly more, you go to the bathroom and start up the heater, then later the tap. You've done the same for her before, so this part shouldn't be too difficult. While you wait for the bath to fill, you have some free time to yourself.
