I’m sprawled on the couch, Kevin’s laptop balanced on my thighs, grinning like a jackass who just won the lottery. The apartment’s quiet—Kevin’s out doing whatever nerdy shit he does—and I’m about to treat myself to some quality “me time.”

His laptop’s password was a joke to crack; dude’s been using “QuantumNerd69” since we moved in. I’ve been sneaking his stuff forever—iPad, scissors for trimming my pubes, even his fancy coffee mug. He’s bitched about it before, but fuck him, what’s he gonna do?

I click open his browser, head straight for my favorite site, and load up “MILFs Gone Wild.” The screen fills with a tanned, curvy goddess in a tight tank top, her massive tits practically spilling out as she moans for the camera. My cock’s already stirring in my sweats, and I give it a lazy rub, settling in for a good jerk.

The video’s heating up—she’s peeling off her top, those juicy melons bouncing free, nipples hard as fucking diamonds. I’m lost in it, hand slipping under my waistband, when a weird shiver hits me. Not like a cold chill—more like my whole body’s buzzing, warm and tingly, like I’m plugged into a low-voltage socket. “What the fuck?” I mutter, but I don’t stop stroking; the MILF’s on her knees now, and I’m too horned up to care.

Then it hits harder—my skin feels like it’s crawling, stretching, moving. My chest tightens, then explodes outward, and I look down just in time to see two massive, heavy tits ballooning under my shirt. “Holy shit!” I yelp. My sweats are shrinking, morphing into these tiny denim shorts that dig into my hips, and my shirt’s now a flimsy camisole, thin straps barely holding up these monster jugs. They jiggle with every shaky breath, nipples poking through the fabric like they’re begging to be sucked.

I’m frozen, staring at my hands—slimmer, manicured nails, soft as fuck. My legs are smooth, thick thighs rubbing together, and there’s this wet, aching heat between them where my cock should be. I reach down, half-expecting my dick, but my fingers brush a soft, slick pussy instead, and a jolt of pleasure shoots through me so hard I gasp. “No fucking way,” I whisper, voice still mine but the soft curves below my neck wasn't.

My tits sway as I shift, heavy and warm, the camisole’s straps digging into my shoulders. I can smell my own sweat now, mixed with this floral, musky scent that’s definitely not me—like some chick’s perfume clinging to my skin.

The door clicks open, and Kevin strolls in, smirking like the cat that ate the fucking canary. “I told you not to touch my shit, Marvin,” he says, leaning against the wall, arms crossed. His eyes rake over me, lingering on my tits, and I swear I see his pants twitch. “Looks like my nanobots worked better than I expected.”

“Nanobots? What the fuck, Kevin?!” I shout, but my voice cracks, and these damn breasts bounce with every word. I try to stand, but my center of gravity’s all fucked up, and I wobble, catching myself on the couch. My ass feels huge, soft, filling out these shorts like they were made for it. “You did this to me? Turn me back, you creepy fuck!”

He laughs, stepping closer, and I can smell his cheap cologne, sharp and tangy. “Oh, I’m not turning you back yet. You ate those bots with your burger last night—self-replicating, body-modifying little bastards. I set ‘em to trigger when you got horny, turning into the person that aroused you. And what do you know? You went straight for the MILF porn on MY laptop.” He picks up the laptop, still playing the video, and grins. “Now you’re the busty bitch you were jerking off to. Well, minus the head. Gotta say, your mug on that body’s fucking hilarious.”

I’m shaking, half from rage, half from the weird, pulsing need in my new pussy. It’s like my body’s betraying me, nipples hardening under his stare, a slick warmth pooling in my shorts. “This isn’t funny, man! Fix this shit!” I try to lunge at him, but my tits throw me off, and I stumble, catching myself on the armrest. They’re so fucking heavy, swaying, brushing against the camisole, sending sparks straight to my crotch. I hate how good it feels.

Kevin’s eyes glint, and he steps closer, voice dropping low. “You know, I could’ve made it worse. Could’ve swapped your head too, or turned you into a fucking cow. But this? This is poetic. You wanna keep using my stuff? Fine. Let’s see how you like being my test subject.”

He reaches out, and I flinch, but he just flicks one of my nipples through the camisole, and I moan—loud, girly, and humiliating. My knees buckle, and I grab the couch to stay upright, pussy throbbing so hard I can barely think.

“Fuck you,” I pant, but it’s weak, and he knows it. My body’s screaming for more, and I’m fighting not to grind my thighs together. The air’s thick with the smell of my arousal, sweet and heady, and Kevin’s grin says he can tell.

“Tell you what,” he says, tossing the laptop on the couch. “You be a good little MILF for me, and maybe I’ll tweak the bots to switch you back. Or…” He leans in, breath hot on my ear, and I shiver, hating how my body arches toward him. “Maybe I’ll code ‘em to make you love this. What do you say, Marvin? Wanna play nice?”

I’m trapped, heart pounding, tits heaving, pussy dripping like a fucking faucet. My head’s still me, but this body—this slutty, curvy prison—it’s got a mind of its own. And Kevin’s got all the control.
