I was sitting on the edge of my dorm bed, scrolling through my phone after today’s work - we had injected me with the nanobots with a plan to test it tomorrow in a safe enviroment when it happened.
The next second my arms moved without me telling them to.
What the fuck? My heart slammed against my ribs. I tried to stop my hands, tried to pull them back into my lap, but they kept going. They lifted slowly to my face, fingers tracing my own cheeks, my jaw, my lips. My head turned toward the full-length mirror on the back of my closet door.
My mouth opened and words came out in my voice, but they weren’t mine.
“Ohhh god… Katherine’s body feels so fucking good already. Holy shit. I can’t believe this actually worked.”
No. No no no. Get out. Get the fuck out of me! I screamed inside my head, but nothing happened. My lips kept moving. My eyes stared at my reflection with this wide, excited look that wasn’t mine.
My hands slid down my neck, over my collarbones where the small tattoo peeked out from under my shirt. They grabbed the hem of my band tee and started pulling it up. Slowly. Deliberately.
Stop! Don’t take my clothes off! I don’t want this! I tried to clench my arms, tried to make my fingers let go of the fabric, but they kept lifting. The shirt came up over my head and got tossed onto the bed. Cool air hit my skin. I was left in just my black bra, the cups struggling a little with the weight of my full, heavy breasts. At 5’6” and 170 pounds I’d always been soft in the middle, thick in the thighs and ass, and my boobs had always been more than a handful. Now they were on display in the mirror and I couldn’t even look away.
My hands reached behind my back on their own and unhooked the bra. It slid down my arms and fell to the floor.
“Holy shit, look at these tits,” my voice said, sounding breathless and way too excited. “They’re so much bigger and softer than I thought they’d be. Katherine’s got these perfect heavy tits with these cute dark nipples. Fuck, they feel amazing in my hands.”
My palms cupped them, lifted them, squeezed. Fingers pinched my nipples and rolled them until they stiffened into tight peaks. Pleasure sparked against my will, shooting straight between my legs. I tried to jerk my hands away. I tried to cross my arms over my chest. Nothing worked. My fingers just kept playing, squeezing harder, tugging on my nipples until I felt a hot throb low in my belly.
Please stop. Please. I don’t want to feel this. I don’t want you touching me like this. My thoughts were frantic, useless. He couldn’t hear me. He was just… in here. Using me.
My hands moved lower, sliding over the soft curve of my stomach. I’d always been a little self-conscious about the gentle roll there, the way my body was plush and thick instead of toned. Now my fingers traced it slowly, almost reverently.
“This belly is so soft and squishy. Way better than my flat guy stomach. I love how it feels when I press into it.” My voice actually giggled. A real, giddy sound. “And these hips… fuck, they’re wide. Katherine’s built like she was made to be grabbed.”
My hands hooked into the waistband of my skirt and pushed it down. It pooled around my ankles. Then the fishnets came next. My fingers rolled them down my thick thighs inch by inch, taking their time, making me feel every brush of the mesh against my skin. When they were off I was left in just my plain black panties.
I tried to clench my thighs together. Tried to keep my legs closed. My body didn’t listen. My feet stepped out of the skirt and my legs spread a little wider in front of the mirror.
My right hand slid down the front of my panties and cupped my pussy through the fabric. I was already warm there. Getting wetter by the second against my will.
“Oh my god, her pussy is so warm already,” my voice moaned. “I can feel it getting wetter. Katherine’s cunt is soaking these panties and I’ve barely touched it. This feels way better than anything I’ve ever done with my own dick. So much softer. So much more sensitive.”
Fingers rubbed slow circles over my clit through the thin cotton. My hips twitched forward on their own. I tried to pull my hand back, tried to shove my thighs closed again. Nothing. The rubbing continued, steady and deliberate, building heat I didn’t want.
This isn’t happening. This can’t be happening. I trusted him with the nanobots project. I let him test them on me because he said it was safe. Now he’s in my body and I can’t stop any of it. I can feel everything. I can see everything. And I can’t do a single fucking thing.
My panties were pulled down next. I stepped out of them and stood completely naked in front of the mirror. My eyes roamed over every inch of myself like they weren’t mine anymore. Full breasts, soft stomach, wide hips, thick thighs, the neat dark patch of hair between my legs already glistening.
My hand went back between my thighs. Two fingers slid along my slit, spreading the wetness that had gathered there. They pushed inside easily. My inner walls clenched around them automatically and a jolt of unwanted pleasure shot up my spine.
“Fuck, she’s tight,” my voice groaned. “So wet and tight and hot. Her pussy feels incredible around my fingers. Way better than stroking my own cock. I could do this for hours.”
My fingers pumped in and out slowly at first, then faster. My thumb found my clit and rubbed in messy circles. My legs started to shake. I tried to stop the motion, tried to clench every muscle in my pelvis to push the fingers out. They stayed. The pleasure kept building, unwanted and unstoppable.
I was forced to watch in the mirror as my own face flushed, as my mouth fell open, as my heavy tits bounced slightly with every movement of my arm. My free hand came up and squeezed one breast again, pinching the nipple hard enough to make me gasp.
No. No no no. I don’t want to cum. I don’t want to feel good from this. Please stop. Please—
My fingers curled inside me, rubbing that spot that made my knees buckle. My thumb pressed harder on my clit. The pressure built fast, too fast. My hips started rocking forward into my own hand even though I was screaming inside my head for them to stop.
“Oh fuck, I’m gonna make her cum,” my voice panted, high and excited. “Katherine’s body is so close already. Her pussy is clenching so hard. Holy shit, this is insane. I’m gonna make her squirt. I can feel it.”
No! Don’t you fucking dare—
My hand pulled away from my pussy for just a second. It reached over to the dresser and picked up the black hairbrush sitting there. The handle was smooth, thick enough to be uncomfortable, rounded at the end. My fingers wrapped around it and brought it down between my legs.
No. Not that. Please not that.
The handle pressed against my entrance and pushed inside. My pussy stretched around the intrusion, the smooth plastic sliding deep in one slow thrust. I felt every inch of it. My walls fluttered around the foreign object. My thumb went back to my clit, rubbing fast and rough while the brush handle fucked in and out of me.
The sounds were obscene. Wet, slick, the brush moving steadily in my soaked cunt. My legs trembled hard. I tried to close them, tried to reach down and yank the brush out with my other hand. Nothing obeyed. My body just kept going, kept fucking itself with the brush handle while my thumb worked my clit mercilessly.
Pleasure coiled tighter and tighter, unwanted, terrifying in how strong it was getting. I could feel the orgasm building against my will, could feel my pussy getting wetter, clenching harder around the brush.
“Oh god, it’s happening,” my voice moaned, loud and ecstatic. “Katherine’s gonna squirt. I can feel it coming. Her pussy is pulsing so hard. Fuck yes, do it, cum for me—“
NO! STOP! I DON’T WANT TO—
The orgasm hit like a punch. My pussy clamped down hard around the brush handle and then released in powerful, rhythmic spasms. Clear fluid gushed out around it in a sudden hot rush, soaking my hand, my thighs, splattering onto the floor between my feet. Another spurt followed, then another. My legs gave out and I dropped to my knees in front of the mirror, still fucking myself with the brush through the violent squirting, still rubbing my clit as more fluid poured out of me in messy, uncontrollable bursts.
My voice kept moaning the whole time, high and thrilled and completely unlike me.
“Holy shit, look at that! She’s squirting so much! Katherine’s body is making such a fucking mess and it feels so good. Oh my god, I’m gonna keep going. I’m gonna make her do it again.”
The brush kept moving. My thumb kept circling. Another orgasm built fast on the heels of the first. I squirted again, harder this time, a long gush that left a puddle on the hardwood and soaked the rug in front of the mirror. My inner thighs were shiny and wet. My pussy felt swollen and oversensitive and I still couldn’t stop any of it.
Please… please make it stop… I can’t take any more…
My body stayed on its knees, brush still buried inside me, hand still working my clit, while wave after wave of forced pleasure rolled through me. My own eyes stared back at me in the mirror, wide and glassy, mouth open around moans that weren’t mine.
And somewhere deep in my head, trapped and helpless, I kept screaming into the silence where no one could hear me.
