Anna's Formula: An Erotic Transformation

by Carlo Thicke

  We kept the apartment fairly cool in the winter to save money - I always liked being under layers of thick blankets anyway. As I sank into sleep I remember thinking it was sort of hot, not cold.

  I dreamed Jenny and Anna were in my room, slowly peeling blankets off my bed. Jenny was wearing her one-piece swimsuit, hair bleached blonde from the summer sun, nipples big as the tip of a pinkie finger bulging through the cloth. Anna - the new Anna - was wearing one of her old T-shirts, some science pun that I never got...but now the T-shirt was riding up so high on her huge breasts that her soft belly was exposed. I couldn't move, it was like I was hardly there. The girls were excited - really excited. They would find the edge of a blanket, pull it off the bed, their hands searching around for another one...their hands met in the middle and they pulled each other close for a kiss. Oh shit, Anna's full, rich, innocent lips and Jenny's experienced, lipglossed passion combined right in front of me. The orgasm I'd had in the shower didn't seem to carry over into the reality of the dream and I felt myself getting hard.

  But instead of just pressing on the sheets and blankets, I could feel my dick surging bigger and bigger, I could see the blankets in front of me starting to bulge upwards. And I could hear them start to tear. Ripping sounds filled the air. The girls gasped with excitement, breaking off their kiss...Anna's fingers fumbling inside Jenny's swimsuit to tease and cup her breasts...The bulge in the sheets was emerging right between the girls and both lowered one hand to stroke and rub at it. With one last mighty surge, my cock sprang out, ripping through the final blankets...huger, bigger than my fucking leg...tall as the girls, pulsing with power, streaming with pre-cum. The girls went crazy for it, grabbing it, suckling it, cooing, wrapping their bodies around it and each other. I bellowed like an animal, I could finally move, my hands reached out to them and my arms, my hands were huge, or the girls were tiny, they squealed with delight as I grabbed their asses and squeezed the two of them tighter around my four-foot cock...I felt a titanic orgasm coming on, and the prospect of it sent the girls into a sexual frenzy, I could see Jenny's hair thrash back and forth as she began to cum...Anna's almond eyes were wide open with the unfamiliarity of bigger and bigger orgasms wracking her stunning, yet innocent body...

  I woke up and it was dark outside. I'd slept far longer than the nap I wanted to. I'd kicked off all the blankets and cum all over the inside of my boxers. I hadn't had a wet dream in years. Christ, just one glimpse of Anna's new body did this to me? What was living with her going to be like?!

  I know what you're thinking. But no, I didn't realize then what was happening to me. It wasn't until much later that I looked back and remembered that Anna didn't drink orange juice. She bought the carton that was in the fridge planning for my return. And she poured that first glass knowing full well what the formula she put in it was going to do to me.

  Chapter 5

  I felt like I was walking through life in a daze that first week. Maybe that's why I didn't notice everything that was happening at first. There was this sense of unreality. What happened can't have happened. What I'm seeing can't be real. I had to put all of those feelings aside because classes were starting back up, but every time I came home in the afternoon, there she was, and they'd surge up inside me again. A combination of disbelief and awe kept coming over me.

  Anna had been right about people's reactions - most people hadn't really had a chance to notice her in the first semester she was at college, since she was unobtrusive, awkward, and tended to only go to classes with 8 graduate students who were more concerned with their grant money than with a quiet classmate. Now, of course, when she walked across campus, she almost caused bike crashes. Everyone knew who she was in the sense that everyone knew there was a smoking hot 18-year-old Asian chick with a big rack around, but she still wasn't mixing with people and wasn't attending the classes everyone else was, so there were more rumors about her than actual knowledge.

  And she didn't really change how she dressed - Anna's nerdy T-shirts were filled out far more than before, and you could easily tell at a glance that she was a knockout, but she didn't do her beautiful hair right and didn't pay attention to what she wore, so the impact on other people was muted. Only up close when she was lounging around the apartment was her full buzzsaw sexuality on display, so it was only me that really knew exactly how far she'd gone, only me that got to experience her leaning against me when we were watching a movie, or brushing past me in the hallway as we passed, the full softness of her breasts against my tight chest.

  I saw a bra thrown over the couch one day and it seemed impossibly big. I couldn't help but steal a glance at the tag - it was "Custom Fit - DD". I guess her build was just too slender for her boobs.

  My friends blew up, of course. My phone was constantly flooded with candid pictures and people asking "is this anna??!?" or "yr roommate is hot" or "can i ask her out". I tried to deflect all the attention. I was worried that someone would really put two and two together and realize that she had created a billion-dollar pharmaceutical in our apartment, and destroy her life to take it from her. I was fairly sure that a genius like Anna would have taken precautions, but a gold mine like "beauty and brains in a bottle"? All the rules would be off.

  It was like Anna's transformation had awakened something in me too. I found myself thinking about sex more often, found myself fantasizing about sex at times when normally I'd be doing other things. At first I just fantasized about Anna. With her newfound beauty, I would lay in my room and watch my door and pretend she was about to open it, maybe half wearing that robe she wore when I came home that first night, slowly sliding into bed with me, running her newly soft, long-fingered hands up my body inch by inch. Sometimes in class I would fantasize about excusing myself from class and running into her in the hallway, and we do it in a storage closet or a professor's vacant office. I imagined turning her over, her rounded ass poking up high into the air, perfect and taut, burying a hand in her silken black hair, riding her from behind as she urged me on, demanded more from me, looked over her shoulder at me with those intense, brilliant brown eyes.

  After a week or so, my fantasies began to range a little wider. Sometimes I fantasized about the New York club girl or Jenny O'Keefe, but often I would be looking at a girl, seeing some attractive feature, and imagining her shifting her shape into a huge-breasted nymph, gorging herself on Anna's pills to become a thing of pure sex and then banging me silly on the living room couch. If the girl I was looking at was too skinny? Pff, I was living with the skinniest girl in the world and she became a "custom fit DD" in only a few weeks.

  And when I fantasized I always got hard. I could be walking down the street, and a stray thought enter my mind and wham. My dick would start swelling up, pushing awkwardly into my boxers. There were times when I had to rush to the bathroom in the middle of class to try to rub one out quickly, to get it to go back down, as my whirling thoughts couldn't stay away from raunchy, over the top sex. It was like I was 13 again, unable to get a grip on my surging hormones.

  As embarrassing as this was, I started to experience whacking off in a different way. I seemed to have more control when I grabbed my dick in my hand than I did before. If I was in class and really needed to just get under control and go back in, I could cum with only a few long, squeezing, firm strokes. If I was lying in bed in the middle of the night and wanted to take my time a bit, I could last...well, I could last as long as I wanted, it seemed. And when I came, it was like in the shower. Just rope after rope of the stuff, huge blasts flaring out. I was kind of freaked sometimes, but didn't dare go to a doctor - again, what would I say? "Doc, I took version 6 of some smart drugs, and they completely work, but I think there may have been a long term side effect." Eventually I just gave in and enjoyed the newly intense orgasms.

  Weirdly, the only thing that really changed as far as Anna's behavior was that she started cooking dinner for us. She explained it by saying that her new medication had some specific nutritional needs and why not just
cook for both of us? It became my job to get the groceries and clean up afterwards. It was pretty high-protein stuff, a lot of steaks and eggs, pork and chicken, with salads and veggies as well. One time I went into the kitchenette while she was working and saw some colored pills in a dixie cup. "Uh...what are these?"

  Anna turned slightly towards me, sweat on her brow from the stove, and smiled. "You don't think I'm done changing yet, do you?" she teased, and touched her tongue to her top lip slowly.

  You probably think I'm three kinds of moron for not pursuing Anna, or at the very least responding to flirtations like that. But the fact was, I had turned her down when she was skinny, and I didn't want her to feel I was only interested in her because of her off-the-hook body. I don't know if she understood that or not, but she didn't appear to be disappointed when I just blushed and turned away. Maybe all she wanted was to see my dick lurch again into hardness one more time before dinner. She got that, that's for sure.

  A month or so into the semester I got a text from Jenny O'Keefe. "Can u come over 2nite?" Anna was sequestered in her room doing something or other, so my chances to get an eyeful were low for the evening. "Sure" I sent.

  Jenny lived in an apartment her rich parents paid for. She was lazy about keeping it up but she didn't actually have a ton of stuff other than her clothes and flatscreen, so it wasn't nasty. Her eyes were red and puffy when she answered the door, so I suspected I knew what had happened - she'd been dumped and wanted either a booty call or a shoulder to cry on.

  As it turns out, it was both. First she was telling me about what a shithead her jock boyfriend turned out to be - not stupid by any means, but he cheated on her and fucked around with her friends. Then she turned her red puffy eyes on me and said she hoped she hadn't hurt me like she was hurting now. Honestly I had forgotten the depression I'd gotten into, but didn't want to say "NOPE LOL I WAS FINE SMELL YA LATER", so I finally said, "It was the right thing for you to do at the time."

  "Oh...you're so sweet..." she moaned helplessly, and leaned into my chest. Her breasts pushed into my chest. I couldn't help but compare them to Anna's. Were they bigger? Smaller? I couldn't tell. They were comparable. Jenny was a bigger girl all around. But quickly I wasn't thinking about that anymore, as we were kissing. We were peeling off each other's clothes and pushing each other towards her bedroom.

  "Ohhh," she moaned when my shirt came off. "Damn, have you been working out? Your muscles seem so hard." She bit and nibbled at the base of my neck, making my answer disappear in a gasp of air. Her body shape had changed a little too. The athletic boyfriend and their shared hobbies had made her stronger, her thighs more powerful as she straddled me, yanking her bra off almost wildly, I heard the elastic snap as her slightly wider back supported her thick, fat orbs more aggressively. She reached down beneath herself. "Shit! You grew, Carl! Ohhh my god, your dick is sooooo big!" I figured this was just her normal flattery, working herself and me up with dirty talk, then she slowly lifted it up, working the head of my dick across her pussy.

  It had been a few months since I'd been inside a girl, and over seven months since I'd been with Jenny...but holy shit. There was no doubt about it. The head of my dick was spreading her out as she pushed it in, it was much thicker than before, much wider. And as I slowly eased into her, her thick hips dropping slowly, she started really freaking out, because there was no question. I wasn't six inches long. Not even close. Seven? Eight? At least eight. And thicker, more powerful.

  "Carl...ohhh shiiit! Carl!! It's so fucking biiiig!" Her penchant for exaggeration really started affecting me and, more or les just on impulse, I growled back, "Fuck yeah, it's big."

  Her eyes flew open in alarmed arousal, a gleeful smile coming to her lips as she realized I would play along: "It's bigger than my old boyfriend's. Much bigger! Fuck, his is like a golf pencil compared to yours!" She was fantasizing a little...and with my new response to fantasy I was really getting into it.

  I remembered she loved it when I got aggressive so I dug my heels into her mattress and really started to hammer upwards into her. "Ugh...god damn! Of course I grew. Sluts like you need it big!" I snarled. I hadn't expected to use so much force but she nearly shot upwards with every thrust. My body undulated like a whip cracking with every powerful push of my hips. Her spasming fingers found their way to my belly where she stroked and half-leaned down, steadying herself as her hips cranked up and back skillfully.

  "F...fuck...Carl...I'm gonna cum! Oh shit, grab my breasts...squeeze them...I'm gonna... oh shiiit!" My head was spinning. She came already? Warm lubrication was spilling down my oversized cock and I still felt totally in control. I slowed my rhythm and sat up on my elbows as she shook and moaned with the intensity of her feeling. I slowly sat all the way up, tipping her slightly backwards, still buried in her, still rock-hard, and kissed her slowly and sensually. When I broke off the kiss her eyes were alert and wild.

  "You haven't even cum yet..." she whispered.

  "You all right with more?" I whispered back. She nodded frantically, so I theatrically cleared my throat and snarled again: "It takes more than just some bouncing slut to get me to cum." I rolled her over onto her back, with me atop.

  "Shiiiit." she moaned eagerly, getting back into the fantasy, gripping my ass with both hands. "You're a monster! You're a fucking monster, Carl!" she yelped wildly. This time with me atop, her breasts bobbed left and right, huge, hard nipples bouncing and swerving as my rhythm accelerated. The sensation of fucking her with a bigger dick, even just a few new inches, was incredible. My new girth was being squeezed and massaged, my newly oversized dick head flared with arousal, and it seemed like Jenny's previous exaggeration of my sexual prowess and power was at least closer to true now.

  I banged her for close to an hour, sometimes slower and more tender, but then we'd get back 'into character' with her begging for 'every inch' and me cursing her as a 'filthy little slut'. Finally she was moaning, as I took her doggy style, "Carl...I gotta stop...please...I need you to cum... For real this time...for real, I can't take any more..."

  "Okay." I murmured, caressing her back, before beginning one last 'animal Carl' snarl: "Arrgh! I'm swelling up...getting harder...pump that slutty ass...I'm gonna...cummmmm!"

  I had gotten used to my new orgasm's volume...but the sensation when actually fucking a girl was far beyond what I had dreamed. And when the first enormous blast of cum shot into her, Jenny went absolutely nuts. She started shaking, shuddering, she had been looking at me over her shoulder, but her mouth dropped open and she crammed her face down onto her pillow, biting and crying out as wave after wave of spunk filled her full. The heat of it was powerful, I could feel the heat squirting back along the length of my dick as she clenched down noisily, feel the clots of sperm dripping back out of her and down my tightened-up balls. She pulled herself off me and it was like a massive relief of pressure, another huge splash of cum across her rounded asscheeks and even up onto her back.

  Jenny flopped back onto the bed, rolling to her back to watch, as if not quite believing it, the end of my climax, massive clots of semen drizzling down my length as I shuddered with pleasure. "Shiiiiit." she said, beckoning me into her embrace. "What the hellll was that?" she gulped as I slid, squishily, into her arms, half-giggling at the sensation of the moisture between us, sweat mingled with our fluids - but mostly mine.

  "I don't know...must be having a growth spurt?" I said.

  "Must be." she replied. "Forget who sleeps in the wet spot, this whole bed is soaked."

  I laughed at her quip and the playful grin she had when she said it. She laughed too. It felt pretty good.

  "Thanks, I really needed that." she said.

  "I won't lie; I was a lot more broken up than I thought I might be when we split up." I said. It seemed less tough on the ego to admit this after I'd brought her to ...a dozen? …crushing orgasms. At least I couldn't think of any better time.

  "Yeah...I wish it could have been easier on you." she said, and kissed my lip
s lightly. "Still, when the booty call text came, so did you."

  "I'll take it." I replied.

  She snuggled lightly into my arms - as much as a full-breasted woman like Jenny can do anything "lightly" in bed. "...so.... not that we're going to do this again, but if we do...I love it that you played along with my teasing? That dominating tough guy thing. Love it. But...don't call me a slut. Whore, horny bitch, whatever pops into your head...but not 'slut'."

  "Sure," I said, curiously.

  She had her head slightly turned away, I saw her in profile through the moonlight through her bedroom window. "I developed early, and...well, when you look like I did at age 12, boys and men start calling you a slut pretty fast. You're expected to always want sex, constantly. Always be available for whatever boy wants to put his hand down your shirt or your pants. And always 'slut', always 'slut'."

  I stroked her hair slowly. "The worst part," she said. "I mean, the worst part of it now...is that I actually really do like sex, a lot, and want it, a lot, but everybody has already trained themselves not to listen, so when I come after someone I'm interested in, they blow it off as nothing special. Like, oh, she's a fucking big boobed blonde slut, of course she wants to bang me." She turned her head slightly towards me. "Your hot roomie is going to have the same problems I bet."

  "What do you mean?"

  "Ohhh, Carl. I knew she was going to be a hottie when I met her, but her freshman fifteen definitely went to the right places." Jenny had internalized an idea that I think a lot of people had - that Anna was having a small growth spurt but a big coming-out-of-her-shell, and had dressed 'down' before. "I bet Asian girls have their own stereotype problems? But big tits and that round ass...I'm guessing 'slut' is going to be part of it."
