Nope, she's oblivious

I pressed my hands over my mouth to muffle my giggles. It was hard though! I was so giddy already, everything seemed so shiny and new, like I got new glasses and cleaned my ears and blew my nose all at once.

This was only level 2? I couldn't wait to see what the other settings were like...

Johnny spoke with a low, slightly husky tone that made my thighs clench. "Okay, I'm gonna hit her with two level 3's, waiting a minute in between to see if it's additive. Then blast her with a level 5 while she's distracted. Got it?"

I nodded seriously and gave him a thumbs up.

He tiptoed down the stairs and into the living room, I followed a few steps behind, resisting the urge to skip. Chloe was exactly where I'd left her, splayed out on the couch in a worn tank top and basketball shorts, her phone flashing lights into her eyes.

Ooh, the lucky bitch is gonna get blasted three times! I was so jealous...

My best friend —boyfriend? Master?— gave up on the spy routine when Chloe failed to notice him. He stood up, offered a glance back to me in the corner, then shrugged.

"Hey Chloe, say cheese!" Johnny stuck his tongue to the side and closed one eye as he aimed from five feet away.

"Wha—"

Zappt!

"—aghhuhhoOOH~" The bratty tomboy moaned like a pornstar when the pink beam hit her in the tummy.

Her nearly flat chest exploded into a pair of perky C-cups and her narrow hips and toned thighs swelled with muscles cushioned by a layer of softness. She made some very interesting noises and her newly-painted toes curled while her legs grew several inches longer. Chloe's arms got a similar treatment to her legs, growing smooth, oddly feminine muscles, tipped with short nails painted sky blue.

I only realized I'd stepped closer when Chloe's practical brunette bob flared into a spiky blonde ponytail with multicolored streaks. The girl cooed and flailed as the transformation finished off with her clothes, the tank top shrunk to a sports bra and her shorts...shortened dramatically.

Bright blue eyes shot open above a button nose and kissable lips, a pink tongue flicked out to lick them and Chloe giggled, sounding like a wind chime. "Hehehe! That was awesome!" She sighed and stretched her arms above her head.

Zappt!

The newly born bimbo's eyes rolled back into her head and she spasmed like a stranded fish, but in a sexy way, y'know? Also, that wasn't a minute, Johnny!

John tapped his chin. "Hmm, I'm not seeing any more changes, maybe the colors in her hair are a little more vivid?"

Chloe was gasping on the couch, glassy eyed and tongue hanging out. I pointed at her soaked crotch. "She definitely enjoyed the hell out of it though, looks like she came her brains out!"

"So that doesn't rule out the mental effects stacking..."

I bounced on my toes. "That also doesn't mean that it does!"

"Do you want to risk it?" He raised an eyebrow at me.

"...Maybe."

Johnny glared at me and opened his mouth to retort, stopping when Chloe sat up.

"That felt great! Do it again!" She grinned widely and hopped onto her feet, only to bounce from one foot to the other like she was warming up for a run. The movements set her new curves to jiggling. My eyes tried to follow everything at once only to fail.

John shook himself and asked, "What's the capital of Washington?"

Chloe blinked her big eyes. "Isn't Washington the President?" She pointed accusingly. "Don't try to trick me, I'm not stupid!"

I giggled while Johnny facepalmed.

"Heyyy! What's so funny?" The bimbo pouted at us, hands on her hips and leaning slightly forward, instinctively showing off her new cleavage.

"...Chloe was never the most studious, so I don't know what I was expecting that to prove." He groaned.

"Well, at least we know it's not literally additive, or subtractive in this case. The IQ scale isn't linear, 100 is the average, 130 is a decently smart person, while 70 is a step up from drooling moron. If we assume Chloe is average or a bit above, two level 3 blasts would make her IQ around 50 at most! Which is severely mentally disabled, she wouldn't be able to speak if it worked like that! Not to mention how bad the whole IQ scale is at measuring intelligence outside of a narrow set of kinda subjective qualities!" I'd started pacing mid rant. I turned to find both of them staring at me blankly. I blushed and ducked down a little. "I mean... it's probably not literally making people that stupid by every measure, just by what the user or the gun itself thinks is hot."

Chloe just looked more confused, but John was nodding thoughtfully. "Yeah, no way it works that way. A couple level 5 shots would make anyone too stupid to really be sexy." He smiled at me proudly, then evilly. "There is another test we can do though!" He spun the dial on the gun. Chloe brightened and perked up in anticipation.

It was my turn to be confused. "Like what?" Wait, did he mean—

Another blast of pink was my answer.
