Sure! Here's a fun, descriptive, and dialogue-heavy take on your prompt, focusing on your friend (let's call him Mark) in Lexi's body after the brain swap:
---
The machine sputtered, rattled, *sparked*—and just like that, it was done. The familiar living room seemed unchanged, but I stared at the new arrangement with a mix of dread and curiosity.
“Holy sh—” Mark, now *inside* Lexi’s body, blinked his long lashes at me, a slow, delighted grin spreading across Lexi’s lips. He immediately craned his neck—long blonde ponytail glinting in the afternoon sun. He gave a theatrical look down his own front, jaw slack.
“Dude, these are *mine* now?” Mark reached up and jiggled Lexi’s impressive bust, the purple bathing suit doing little to contain his enthusiasm. “This is—*awesome*,” he said, voice an octave higher, sounding weird but giddy.
“Yeah, yeah,” I said, glancing at the empty spot Lexi had occupied. I heard the front door click shut; she was already gone, off to test drive being a guy somewhere else.
Mark did a little hop in his—or *her*—bare feet, watching his new curves ripple and bounce with every landing. The bathing suit hugged Lexi’s hips, the fabric creeping up—just as she always complained, though Mark seemed to love it.
“Ha! The—what did you call this, a ‘jiggle test’?” He jumped again, chest bouncing in time with his laughter. He turned a little, admiring his own *firm* yet big backside in the mirror by the fireplace. “Lexi’s ass oughta have its own gravity field,” he said, giving it a slap that made the curve wobble.
“Mark, you’re gonna break her body before she comes back,” I warned, but his excitement was infectious.
“I’m *never* giving it back. Kidding, kidding…” He strutted a little, doing a half-hearted twerk that looked more like a dance. The bathing suit shifted higher—wedgie territory—and Mark deftly fished it out, cackling. “I get how girls end up picking at themselves all day. This is intense!”
He paused, hands exploring the smooth skin of Lexi’s arms, then her thighs—his palms gliding admiringly over the contours. His fingers eventually ran up Lexi’s fit stomach—he paused at her chest again, squeezing curiously. “These are heavy! Is this why Lexi walks kinda… y’know, chest out?” He tried to mimic her stride, trotting in circles around the rug.
Finally, Mark’s hand brushed his ponytail, feeling the silky thickness of Lexi’s signature mane. He grinned, grabbed it tight, and *whipped* his head like a popstar—only to immediately yelp. “Ow! Crap, that’s my *eye!*”
I couldn’t help but crack up. “Careful. It takes practice. Maybe try not to concuss yourself with your own hair.”
Mark blinked, rubbing his eye, then back to admiring Lexi’s curves. “Everything about this body is fun. It’s like… a sports car compared to my old sedan.” He poked his new hip. “I get it now. Lexi was right—guys never have to think about half this stuff.”
He paused, stretching, the bathing suit riding up again. “But also… damn, I look *hot*.”
I rolled my eyes, but couldn’t deny it—Mark, for now, had definitely come out ahead in the swap.

Prompt: My girlfriend has been arguing with my friend about who has it easier between guys and girls. I was starting to get annoyed about it so I suggested we use my brain swapper machine. They both agreed. I fired up the machine and swapped them. My friend looked down at his new ass and laughed. He is fired up to try being a chick especially one as hot as Lexi my girlfriend. My girlfriend left the house deciding to live life as a guy for a bit. Focus on my friend in her body more. Maybe he jumps up and down for a jiggle test or tries to twerk. His hands trace his new body until he reaches his ponytail which he grabs and whips around until he hits his own eye. It seemed like everything about Lexi's busty and curvaceous blonde body was fun for him. Write with lots of dialogue and good descriptions and use names. make sure to be as descriptive as possible. My girlfriend is a blonde with a big yet firm booty and large boobs she is wearing a one peace bathing suit that shows off her backside and gives a slight wedgie
