Kathrine's story

I had just turned 18, I always was considered a tease. I had a short plaid skirt on and a top that you could see my nipple thru. my brothers and his friends always smoked in the basement. I had no idea that the nanotechnology was spreading and that my brothers and his friends had already been infected when I went to check on what was up and sneak a few hits off a joint from them.

They were all watching something on their phones when I came down. " hey guys what are you up to?"

"Oh well actually can we test something out. do some jumping jacks for us" Brian her brother friend says. He was a smelly geek type but a big guy at over 6 foot compared to her 5 ft height. Her whole family was short and I hated it.

"Hey what the hell why am i listening" i say freaking out inside as i start jumping my tits bouncing and my skirt flowing up to show off my ass.

"Fuck man it's real, hey get on your knees and blow us all." John another of the usual guys who hung around their garage says. He had been creeping on her for years before she was 18 and was following my bouncing tits as i jumped.

"Hey i get first she's my sister" Chris says claiming first go at my cute face. He wiped out a dick that was larger than i every thought possible at 14 inch and as wide as a soda can.

"Wait why are you doing this please let me stop.". I get silenced as my body starts putting it in my mouth at this point. I cry and can't understand why i can't stop.

"Fuck she is only sucking the head come on and get to the base like a porn star" Chris commanded and i gagging as my body betrayed me yet again and start trying to **** it past the back of my throat.

"here i'll help you out" Brian say He grabs me head and pushed me down on chris cock. spit coming out from around my lips as i was impaled on it i was sputtering and **** and gagging as they watched. her jams me back on and off it and i feel it penetrated my esophagus painfully stretching my throat as i help him fuck my throat spit covering his shaft and balls as i was fuck up and down in it till my brother down cums it. The fluid hitting my stomach like a fire hose.

"My turn next, i am the next oldest. Caitlyn lean over the arm of the couch backwards and open your mouth wide for me." Next up was my second brother.

"Please come on guys what happened to you all" i cried i didn't know how thing were changing so my complaints didn't matter anymore as they hadn't told me anything yet.

"short answer is your new use in life is as our cum dump. This scientist made it all possible." He tells me as He begin fucking my face as i hung over backwards. The guys were amazed at how my throat bulged as he fucked my throat as if it was a pussy. At the last second he pulls out to cum in my eyes. The fluid burns them, and all I can see is a blurry whiteness after that. After that my brotherslet his 6 friends lined up to fuck my throat. my tit's pulled and slapped the whole time.

"Fuck it i am going to fuck her ass i can't wait for her mouth again Chris says as he was rock hard again. The sight of his petite little sister getting cock shoved down her throat had him more than ready. He had known at first he should be protecting her but his response was twisted by the nanotechnology erasing inhibitions and rewiring his brain. They had watch the video that morning of the basketball game and when the physical changes started realized it was real. His friends had been talking about using his sister when she had come down. It was to hard to hold back and he claimed her ass first.

I didn’t know all of that so felt betrayed and disgusted by them as i felt the to big cock press against my virgin ass. I screamed on the cock in my throat at the cock was shoved brutally in my asshole. every inch hurt as he jammed all 16 in and they ignored my pain as they took turns. For the next few hours they passed me around like a rag doll as they all tried out fucking me in every way. Ignoring my crying eyes and painful expressions as they triple stuff me and laughed about how i was the perfect size for a fuck doll. My brothers friends all taller fucked me hanging on the cocks not even touching the ground. I was subjected to what a porn star wouldn't be able to do till years into their careers. My body held together by the nanotechnology even as it should rip from the over sized cocks. They had each cum in all three holes before they start really being perverts.

"Hey lets see what we can fit, those girls at the game looked pretty hot stretched out." Brian says as i thought i was going to finally get a break.

"Fuck yeah Caitlyn would be hot stretched out a bit. Do a split for us on the table. Keep your legs wide for us." Chris tells me and i feel my body move on its own. My holes already sore and raw from all the fucking

"What the hell is wrong with you all please no more." I begged as i felt them pushing a soda bottle in my ass. My pussy was assaulted with a baseball bat by my brother. The shaft was harder than their cock and hurt as it was pounded against my cervix till it gave way. The bat was pushed my belly out pain fully as i felt like my cervix was tearing apart. the technology not letting me tear though

"No no please guys stop." I said as he pulled out and pounds it in fast and hard. My body shakes and i passed out for a moment. This didn't stop the next guy taking a turn to batter my insides. I came to with a scream as my tits had just had vice grips attached to my nipples. My perky c cup breast then got pulled and twisted by them as they continued to fuck me hard with the bat. Ryan taking time to really pound it deep.

fuck man now she can take our cock all the way by now lets fuck her again. Brian says after getting the bat handle deep in her. The shaft pushed out her skin and was in-between her red and swollen tits. The vice clamps still on them pulling them apart. They took turns fucking my womb and washing me out with their loads of cum for the next few hours. My mouth being used again to warm up each guy before there turn in her batter open cervix. after the continued with their fun and stuffed base ball bats up my holes

"Boys were is your sister i needed to check on something " i hears yelled down the steps and heavy boots coming down. I think i am finally going to be let go when dad sees them fucking me with two baseball bats in my pussy and another up my ass.

"Damn you guys already heard i guess. Well i want some time with her so go home till tomorrow boys." My dad says and i realized i am not going to get any mercy from him..
