"Mariah."
Lucas burst out laughing. Bradley was indignant. "I wanna be a gwow..." he started babbling but I couldn't hear him.
Mariah and I stared at each other. We both were stunned. She was going to be an athletic teenage boy. I was going to be a fat, depressed girl on her way to college.
I always wondered what it would feel like to be fat. That constant mass of stomach sticking out the front of you, pointing whichever way you were going. The huge buttcheeks filling and stretching against your pants. The massive, heavy breasts, pulling down on your neck and spine. The humiliation of being swollen with heavy fat after years of craving snacks, too humiliated to exercise in public, difficulty buying clothes. The constant jiggling up and down your body as you walk, as you drive, even as you turn over in bed, constantly reminding you you are less worthy, you are powerless.
Mariah, I imagined, always wondered what it was like to be a boy in great shape. Your strong muscles lifting anything in your way, your cock and balls flopping around in your pants, as you walk, as you drive, even as you turn over in bed, constantly reminding you you are worth something, you are powerful.
We were soon going to have radically different lives.

After a couple of days of denial and protests, I had given into my fate. My sister, Mariah, would soon be in my body forever, and I would be in hers. I knocked on her bedroom door.
"Mariah, should we start to introduce each other to our new bodies?" I asked.
"I was thinking the same thing!" she told me, cheerily. "I can't wait to feel what it's like to be skinny, and especially to have a dick. I can't wait to pee standing up!"
I was so humiliated, I could feel my face burning red. "I wish they pulled someone else's names out."
"Come on, David, can you imagine if one of us had to switch bodies with Brad?" She laughed. "Trapped as a 4-year-old boy? 100cm tall, with that tiny little dick?"
I chuckled. She was right, that would be more horrible for either of us, and for Brad too. "Okay, it could've been worse."
"Or Mom? One of us being a pudgy 41-year-old mother?"
"Okay, I get it. It's probably the best that we're almost the same age. But still, Mariah... I like being a boy. I don't want to think about showering in your body and wearing your clothes. And, I don't know how to say this...."
"You're upset that you're going to be fat. I get it. But you have the good health habits and the energy. I'm sure you'll turn into a healthy, hot woman pretty quickly. I'll turn into a fat guy in your body."
She had a point. "Should we get this over with? I don't want this to be a surprise on Saturday."
"Ok," she said, catching my drift.
I took my shirt off. She took hers off. We were going to look at our new bodies, naked, for the first time. After all, we would be living in them for the rest of our lives.
Suddenly Brad burst in. "You two will switch bodies?" he asked.
"Yes," Mariah said.
"Mariah's gonna have a penis?" he said, giggling.
"Yes, I am," she said, beaming.
"David's gonna have a vagina."
"I—", I struggled with the words.
"David's gonna have boobs!!" shouted Bradley, giggling frantically. "David's gonna have no penis!!"
Mariah unbuttoned her jeans and pulled her pants off. Then she took her panties off. She had a patch of dark hair between her legs. "That's right, Brad! David's gonna look like this. You and I will have penises, Brad. Not David. He'll be a girl, and girls don't have penises. He'll have to pee sitting down for the rest of his life."
I was mortified. I stared at Mariah's crotch, in disbelief, knowing soon that would be part of my body and I could never, ever get rid of it.
"Ok, Brad, leave us alone," I muttered.
Brad scampered off. Mariah took her bra off. These were the first boobs I'd ever seen in real life. And in a few days they would be mine, forever. "These are so heavy, they hurt my back, my neck. And men never stop staring at them. They're constantly jiggling and getting in the way. If you lose weight in this body they'll get smaller, but even then they'll just sag and stay just as jiggly."
I never really thought about what it was like to have breasts, especially huge ones like Mariah's. "Is it okay, though? I mean, you get used to it, right?"
Mariah frowned. "Not really, honestly. David, you're going to have a lifelong struggle trying to feel comfortable after the swap. These things will always be in your way and always feel sore. It'll be so embarrassing to have them stuck to you. To have people staring at body parts that are always right in front of you and you can't put down. Maybe someday you can have a reduction. You have that to look forward to."
I felt a creeping horror come over me. I stared at my nude, overweight sister. My new body. Forever. No escape, no reverse.
