The Drug Trial by Guhbone

The Drug Trial

by Guhbone

So I needed some cash. Weeks of partying, food, rent, tuition and books tapped my funds and put me periously close to all out bankruptcy, I swear.  I should cut back on the booze, but hey, it's college.  That's half the point.  I signed up for an 8-week drug trial with some company called Yiroflex, or Yikkocom or something - they promised a $3000 payout for the trial, $1000 up front.  That was some good money.

 

My first meeting with Yiroflex was a group session.  No one really talked much, and you can tell that people were uncomfortable.  I was a little nervous myself.  There were only about, oh, 15 or so people there, mostly men.  Some doctors went through the pamphlets and whatnot they gave us, and then set up individual appointments.  Mine was next Tuesday.  Turns out the drug they are testing is some newfangled body chemical balancer or somesuch, that was supposed to increase vitality and general wellbeing.  I really didn't understand it - I went into Marketing for a reason.  Science wasn't exactly my strong suit.  I guess it was like they were making a prozac for the masses.

 

My appointment was just like a regular doctor's visit - they took down my stats: 5'11", 165lbs, average build, regular blood pressure - and then ran me through a small series of tests with weights, a treadmill and some stair machine.  After which I signed the contract papers, received the drug trial, instructions to take one pill twice a day, and a nice cheque for $1000 made out to me, Jake Lawson.  Life was good.

 

I partied it up that weekend.  The pill, though a bit chalky, didn't seem to have any discernable effects on me yet.  I was maybe a bit hornier than usual.  On Friday night, I slept with a cute girl from my Friday lecture named Katie.  She was a pixieish girl, no more than 5'1", with a slim build, perky little tits and cute face.  I remember her being shy, but she seemed to really pick up on my randiness and, though we barely knew each other, we were all over each other that night and ended up back at her apartment.  Saturday night I went to the bar and, though I didn't go home with anybody, the girls were all over me.  Now, I'm not an ugly fellow, but nor am I some knockout hunk.  Maybe it was phermones or something.  Either way, I was getting more action than ever.  This one chick Stacy gave me a blowjob in my car.  I can't fucking believe I did that!  She gave me her number, telling me to call her later.

 

After 2 weeks of the drug I began to notice changes in my body.  My virility, which was obviously off the charts, was now complemented by frequent erections.  And, to my surprise and delight, my erections were larger than ever before.  Whereas I used to be 5.75" long erect, with 5" girth, I now measured a full 6" long and nearly 5.25" around.  I also felt more alert, fit, and generally healthier than ever.

 

I was not sure if these were known side effects of the drug, but none of my literature mentioned it.  I made a note to ask the doc on my followup visit on Tuesday.

 

That night I went to a party in my dorm and hooked up with Chelsea, a girl I've hooked up with before, but never got into anything serious.  She was a nice full-figured brunette, about 5'5" tall, a little on the chunky side but with really nice rack.  D-cups, I think.  She fucked like a minx in heat, and, with the way I've been feeling lately, I gave her all she could handle and more.  We passed out on my bed.

 

The next morning I slid out of bed and went to the washroom.  Sex last night must have been good because I was sporting a huge morning wood.  After awkwardly peeing with my rigid cock, I returned to my dorm to find Chelsea getting dressed.

 

"My bra doesn't seem to want to clasp," she said, "Can you help me out Jake?"

 

It was tight.  I had trouble getting the loosest hooks to grab.  I did happen to see the "36D" printed on the tag, though.  Nice.

 

"I have to get back home, I have a big test Monday," she said as she headed out the door.  "Last night was nice, Jake.  Maybe we could go for coffee or something...?"

 

"That'd be nice," I replied.

 

"Well, goodbye."

 

"'Bye," I said.  Chelsea was pretty cute.

 

My appointment Tuesday was similar to the first, but I got the impression that it was...hurried or something.  It was like the doctor was distracted.  Come to think of it, he kind of deflected my question about my penis.  No matter.  I had another cheque for $500 and a the rest of the trial.  I now had enough of the pills to last me the remaining 6 weeks.

 

I was ansy the rest of the week.  I just had so much energy I couldn't sit still.  I was all over the court in my rec volleyball game and was barely even tired!  And Friday, after class, Katie practically jumped me.  I don't know what came over us, but we had quick sex in some random stall in a seldom used bathroom.  I mean, I'm not a timid guy, but this was another level for me!  I wanted more, but Katie was gone for the weekend.  Damn, but she was hotter than ever.

 

I didn't see Chelsea in the common room of the dorm that night, which was odd, so I decided to give Stacy a call.  I was hornier than ever and needed some release.  This wasn't like me at all - I usually don't hook up with chicks from the bar, and I certainly don't initiate further contact.  I ended up meeting her and her friends at a different bar and, after getting loaded, went to her place.  Her and her two friends rented a house not far from the university.  I fucked her, twice, and ended up taking a cab home.  I think she was just using me, but at this point, I didn't care.

 

I woke up the next morning, groggy and hung over.  I stumbled to the washroom, stood in front of the can and pulled out my cock.  And kept pulling.  I snapped awake immediately.  My cock was huge.  I finished my piss and rushed back to my dorm.  Pulling a ruler out from out of my desk, I rested it against my flaccid dick: 6.5".  Soft, I was longer than I ever was hard.  And it felt thick.  I worked myself up, amazed at how big it looked, and measured again:  10.25".  Grabbing a string I wrapped it around my throbbing cock and measured.  Unfurling it and measuring it, it came to 6.25".  Holy crap.  Even my balls felt bigger.

 

I looked at my cock, and the bottle of pills on the desk.  This wasn't part of the deal, but I can't complain.  I had a ten inch dick.  I popped in my morning pill, resolving to continue with the trial.  Plus if I stopped, would my dick shrink?  I didn't want that.

 

I was pretty damn cocky - pun intended - at the dorm party that night.  It was a pretty laid back affair, and I was again surprised to see that Chelsea wasn't there.  Damn.  I was hoping to score some tail with my new schlong.  Fucking ten inches.  Damn.  I decided to go to her floor and see if she was there.

 

I knocked on her door.  "Chelsea, you there?"

 

"Go away Jake," I heard Chelsea mumble.

 

"C'mon, open up!" I knocked again.  I waited in silence.  Finally, Chelsea opened her door.  I wasn't ready for what I saw.

 

Chelsea got fat, like twice the size I remember.  Her massive knockers tented her shirt, but it didn't hide the buldging belly beneath.  Her new fat ass stretched the threading of the pajamapants she was wearing.  She was at least 220 lbs.

 

Everything about her was bigger - her tits, once nice 36Ds, were now bloated zeppelins.  Below them her flabby gut was outlined against her shirt, with a hint of an apron hanging out.  Her sweats did their best to contain her pear shaped body.  Wide hips and thick thighs spread out across her bed as she sat down.  Somehow Chelsea managed to gain 50 lbs in less than two weeks...and she made me incredibly horny.  She was like that curvaceous women of before, only...more.  I wanted it.

 

"Chelsea...?" I stammered.

 

"I don't know what happened Jake." The words spilled out of her as she fought back tears.  "I just keep waking up every morning fatter and fatter.  I didn't even notice it at first, and then it started happening faster.  I'd go to sleep and wake up 5 or 10 lbs heavier the next morning!  I'm 223 lbs!"  She was full out crying now.

 

I sat down next to her and tried to comfort her.  She nuzzled into my shoulder.  I couldn't help but caress her body.  It was incredibly soft.  She calmed down, but I didn't let her go.  Chelsea looked up at me, and we kissed.  And then really made out.  Things were getting hot.  I stripped off her shirt, admiring the way her body seemed to flow into the bed.  I kissed her breasts and fondled her lovehandles.  She worked off my shirt and pants.  She gasped when she saw my erect cock.

 

"You're so...big," she breathed.

 

"You weren't the only one growing," I quirked.

 

I pushed her back onto the bed and stripped off her pants.  Creamy thighs greeted me and I fell into them, licking and caressing.  I moved my face between her legs, feeling the soft smooth flesh around my head.  With a deft tongue, I made Chelsea orgasm.  I then moved my body into position above her quivering form and gently slid my cock in.  I lovered myself onto her softness and begaun thrusting.  Chelsea's body enveloped me and moved beneath me.  I came mightily.

 

Afterwards, we laid down and talked.  She said she went to the doctor, but he didn't really believe her, and anyway he didn't find anything.  She wonders if maybe it's glandular, or she was just meant to be fat.  Her mom and sister were fat.  I said nothing committal.  I had my own suspicions that I did not want yet to voice.

 

I quietly left the statisfied Chelsea with a promise to do breakfast tomorrow.  Meanwhile, my mind was twirling.  Did Chelsea's rapid weightgain have anything to do with me?  The coincidence seemed to much to me, and I couldn't help but draw the connection.  But then again, maybe it really was a coincidence.  How would it have worked, anyway?  My cum made her fat?  No one can just get fat from that.  Plus, I haven't gained a pound.  She doesn't know about my drug trial, so maybe I'll just keep quiet.  Maybe she just really let herself go.  Doubts still nagged at me, but I pushed them down.

 

I got back to my dorm to hear the beeping of my cellphone.  Someone left me a message.  I flipped it open and saw at text from Stacy.  'can u call me?' was all it said.  It was late, so I opted to call her in the morning.  After popping my evening pill, I flopped into bed and fell asleep.

 

The next morning I walked over to the cafeteria to meet Chelsea for breakfast.

 

She seemed...softer. 

 

"I weighed myself this morning," she said, "I'm up to 229lbs.  I somehow gained 6 pounds yesterday.  My gain had slowed down to almost nothing, but all of the sudden I'm gaining again.  Can a person gain that much weight in a day?"  I shrugged.

 

I noticed that she had a massive breakfast - four pancakes, five sausages, diced potatoes, cheese, three eggs - but I didn't say anything.  She also helped herself to seconds at the Sunday brunch.  I had some french toast.

 

I was making my way back to my dorm when my cell rang.  Stacy!  I forgot about her.

 

"Hello?" I answered.

 

"Hey Jack," she replied.

 

"It's Jake."

 

"Yeah, whatever.  Can you meet me for lunch at McBurger Queen on Hillsdale?" she asked in a tone that suggested it was not really a request.

 

"Yeah sure," I answered.

 

I got there a little early, so I sat down and waited, keeping an eye on the door.  After about 15 minutes a red-haired, sunglass wearing bombshell sauntered in.  She had nice round hips, long legs, wasp waist and juicy double Ds.  My crotch grew tight.  And then she sat down at my table and removed her sunglasses.

 

"Stacy...?" I stammered.  I admit that I was drunk both times I hooked up with Stacy, but were her tits always that big?  I seemd to recall that she was no more than a nice handful, a good C-cup.  I'd need two hands now.  Plus, I swear she had slim hips and a tight ass.  I must have been hammered.

 

"Hey Jake," she quipped, "Ever since I slept with you I've been feeling great, and looking great."  She leaned back and I got a full view of her full bosom.  Her v-neck exposed a nice amount of cleavage.

 

Taking her bait, I replied, "Yeah, I've been feeling great myself."

 

"Mmm hmmm," she murmured.

 

We quickly ate some lunch and left the food joint.  I followed her back to her place and started making out immediately once inside the door.  My horniness was reaching new heights and she was eager to oblige.  She pratically tore my shirt was off.  We backed into her bedroom, discarding clothes as we went.  I pushed her naked form on to the bed and watched as her breasts flopped to her sides.  They were huge.

 

Caressing those massive tits was glorious.  Her body was a perfect hourglass.  I climbed between her legs and slipped my raging erection into her moist sex.  She gasped.

 

"Oh god, you have grown!" she cried.

 

We fucked wildly and passionately and within minutes we both orgasmed.  I rolled over, panting.  That was intense.

 

"Wait here, I have a surprise for you," Stacy said as she bounded up from the bed and left the room.  How does she still have so much energy?  I just laid there.

 

"Surprise!"

 

I sat up frantically and tried covering my crotch.  She brought in her roommates!  What the hell?!

 

"Jake, this is Tara and Marcy, my roommates.  You met them at the bar," Stacy started.

 

Both Tara and Marcy were in only their underwear.  Tara was tall and slim and sporting smallish B-cup tits, with long brunette hair and an angular face, but with a warm smile and full lips.  Marcy was shorter and plumper, with dark blond hair, a cherubic face with pinched eyes.  She, too, had B-cups but they were resting above a sizable belly. She looked like she went through the Freshman 15 a couple of times.  I had a sudden urge to caress it.

 

"What the hell, Stacy?" I yelled.

 

"Oh simmer down Jake!" she yelled back, "When the girls saw me the next day, we figured it must be you.  Do you have like magic sperm or something?  Well, whatever.  We are going to fuck you silly."

 

Without warning the girls jumped me.  I was powerless to resist, and found myself unwilling to.  It was like my body was ignoring my mind.

 

Stacy was straddling my chest and rubbing her knockers in my face.  They were quite soft.  Tara and Marcy were each straddling one leg and playing with my cock and balls.

 

"Wow, he IS big," I heard Tara or Marcy say.

 

One of them started sucking my dick.  I grew hard and began to instinctively thrust my hips.  One girls was expertly caressing my balls and playing with my grundle.  I came within moments, but was given no respite.  I felt the girls switched off and a new round of fellatio began.  Miraculously, I remained hard.  Even more miraculously, I came again as big as the first.  By this time Stacy moved her snatch into my face, and I ate her out.  Watching her buck above me was extremely erotic.  Judging by the slim legs straddling my hips, I guessed that Tara had plunged herself onto my rod.  I came for the fourth time in less than an hour even while I could feel Stacy come above me.

 

Like a merry-go-round, the girls rode me all afternoon.  I had a seemingly inexhaustible supply of cum, and no trouble maintaining an erection.  Finally, exhausted, all four of us collapsed on the bed.

 

"So...," said Stacy between breaths, "What's your secret."

 

"Some new pills," I huffed, "I'm on some clinical drug trial.  It all started then."

 

"Keep taking them," she replied, "because that was the most incredible sex I've ever had."

 

Shortly thereafter I got dressed and made my way back home.

 

"We'll have to do this again sometime," Stacy said as I left.  Definitely.

 

"How long do you think it will take?" I heard the girls ask amongst themselves as I walked to my car.  What a crazy weekend.  I took a double batch of pills that night.

 

I was feeling better than ever the next morning.  I practically bounded to the washroom I had so much energy.  Inspecting myself in the mirror, I liked what I saw.  The small bit of flab on my waist had disappeared, and the makings of a six-pack were evident.  My muscles seemed tauter, too.  My dick was as big as ever.  Measuring, I found that I grew some more, to 10.75 inches.  My balls felt bigger, too.  These pills were miracle pills.  I took another double dose.

 

The day went by quickly. I saw Chelsea in the hall and said hi, and admired her huge ass as she walked away.  I had to hide a huge erection for nearly an hour after that.  The week went by just as quickly.  I hooked up again with Stacy and her friends Thursday night.  Stacy, if you can imagine, was even bustier.  Huge canteloupe orbs strained against her tight shirt, and her flaring hips looked enticing as her low-rider jeans cut into her.  Tara, who was nearly as tall as I was, now had her own C-cups.  She didn't seem any fatter.  Marcy, on the other hand, looked like she gained another 15 pounds on her gut.  She didn't seem to notice.  I pegged her at 160 lbs.  Her tits seemed bigger, too.

 

Life was good.

 

For my week 4 appointment, I felt great.  The doctors took my stats, didn't say much, and then handed me another checque and more pills.  I think they forgot that I had a full supply, but I didn't say anything.  By then, I had bulked up to an impressive 175 lbs.  My abs grew more defined, my arms and legs were bigger, and my dick had grown to a full 11".  I was also nearly 6'.  I decided to continue my double dipping.

 

Chelsea confided in me that her weight gain spiked again, and that she was up to 242 lbs.  And a 44G-cup.  She couldn't believe how big her tits had gotten.  She seemed happy, though.

 

Wednesday brought another round with Stacy, Tara and Marcy.  Stacy was looking dynamite - round F-cup tits capped with large nippled hung proudly in the air.  A softened torso sloped into wide, sexy hips and a round bubble butt.  Soft smooth legs finished it off.

 

Marcy was turning into a fatty.  Her belly was getting really big.  She didn't seem to care, as I was almost uncontrollably attracted to it.  I caressed and sucked on it while fucking her, and loved the way it drooped when she leaned over.  She was probably up to 190 lbs.  Tara just seemed taller and bustier.

 

Friday was a shock.  I saw Katie for the first time in while.  I think she was at the gym the whole time.

 

"Hey Jake," she said as she sat down next to me.  Her once tiny pixie body had transformed into a ripped goddess.  Slim limbs were replaced by corded muscles rivaling my own physique in size.  While it was nothing outlandish - a trained athlete would have a similar build - it was unusual on her.  Plus, she got to that state in a matter of weeks.

 

After class, she pulled me into a washroom.  She was strong.  Within moments she had us undressed and crouched to work on my cock.  She got me hard, climbed on my torso and impaled herself on my cock.  I rode her hard against the wall with her legs wrapped around me.  We came together.

 

Chelsea sought me out the next night, looking for some release.  She was 270 lbs now.  Big fat tits flopped onto her belly as she removed her shirt and bra on my bed.  Plush thighs spread for me as I plowed into her softness with relish.  I came shortly after she did - a big load, bigger than ever before.  She then did something she had never down before.  She rolled over and crouched between my legs and placed my cock into her mouth.

 

"You've gotten so big," she cooed.

 

I grew hard in her mouth.  Chelsea stroked my cock and sucked my head.  I came into her mouth.

 

Sitting up with a smile on her face, she got up and walked around.  I watched her ass jiggle in the air.

 

"Hey, what are these pills?" she asked suddenly, grabbing the bottle off my desk.

 

"Oh, they're from this drug trial I'm in," I replied, "I started taking them about 5 weeks ago."

 

"Hmmm..." she murmurred, placing her index finger against her pouting lips.  She opened the bottle and poured out some pills into her hand and waddled back to me.

 

She slipped a pill into my mouth and kissed me.  "I want more," she breathed, glancing at my cock.

 

I swallowed.  Chelsea placed herself over my groin and worked my erection into her wet snatch.  I placed my hands on her fat hips and thrust into her.  Her whole body shook as I pounded into her like never before.  She slipped another pill into me and I dutifully swallowed.  And then a third.  I climaxed with a massive thrust that caused Chelsea to cry out in pleasure.

 

Exhausted, she pratically collapsed on top of me.  I felt the weight of her body press me down.  It was unbelievably erotic.  We fell asleep into each other's arms.  I was starting to fall for this girl.

 

I awoke to an empty bed and a note from Chelsea telling me she'd call me later.  I idly scratched my crotch.

 

And found a lot of it.

 

My fat dick hung heavily over my hip.  Standing up I felt it slap against the side of my leg and dangle halfway to my knee.  I grabbed my ruler.  The sucker was 9.5".  With a few deft stroked I worked up an erection.  14.5".  Jesus Christ.

 

I poured my pills out and counted 17 pills.  Doing a quick calculation, taking into account my double dipping, I should have had 22 left.  I must have had 5 pills last night.  I scooped them up and put them back in the bottle.  I needed to see my friend Trent.  He'd figure this out.  He's a grad chemistry student, after all.

 

My pants didn't really fit.  They were too short.  I checked my height and found I was 6'1".  I grew an inch overnight?  I changed into looser pants and grabbed a big T-shirt.  15 minutes later I was at his apartment banging on the door.  No answer, crap.  I went back to the  university, hoping he was in the lab.

 

I met Katie in the hallway.  She was remarkably cut, noticeably bigger than on Friday.  How powerful were these pills?  She wasted no time in taking advantage of our chance encounter. I was powerless to resist.  My instinct overwhelmed my senses and fucked like animals in my dorm.

 

She was stronger, more ripped, and maybe even taller than before.  She had grown from a slight pixie into a dedicated body builder.  And she revelled in it.  Flexing for me, I was impressed with the peaks formed in her biceps.  Ridged abs complimented defined thighs and taut calves.  She looked as though she spent hours in the gym each day.  And I gave her a workout, coming into her more than once.

 

With the extra dose of the drug in my system, I worried what it would do to her.

 

Incidentally, she left my pad to hit the gym.  She loved the progress she was making in so short a time!  I don't think she made the connection to me, thank god.

 

I had just gotten my pants on (for the second time today) when my cell rang.  It was Stacy.  She seemed panicked.  She implored me to come over.  I sighed and said I'd be right there.

 

I knocked on Stacy's door when I got there, and met my third shock of the day.  Tara answered, buck naked, and she simply towered over me.  She was probably 6'8".  Still slim, but now sporting at least D-cup breasts, Tara was a marvelous sight.  Well, at least D-cups if they were on a person of regular height.  I have no idea if that measurement system still applied to Tara.  Her nipples were practically at my chin.

 

"Hey shorty," she laughed and rubbed my head.  I just gaped.  "Thanks for the pills, by the way."  Tara idly tossed a bottle of pills in her right hand while popping another in her mouth with her left.  She sauntered off towards her room.

 

My second batch of pills! I didn't even realize they were missing!  The girls must have stolen it from my bag last Wednesday night.  What the hell did the pills do to them?

 

"Stacy?" I called out, leaving Tara to her own devices.  I started walking towards her room.  And stopped dead in my tracks outside of Marcy's.

 

"Hey Jake," Marcy said non-chalantly and pushed another handful of chips into her mouth.  She was sitting naked against the headboard of her bed watching TV, bags of food strewn about.  Her left arm rested idly atop the biggest belly I have ever seen.  Marcy's belly had swollen into gargantuan proportions.  It protruded from her torso to rest between her legs on the bed.  Fat tits hung to either side, capped with large areolas and thick nipples.  She pushed another handful of chips into her jowls, a deep double chin evident.  I stood mesmerized by the sight. 

 

"Like what you see?" she quipped, "I know you do. You loved playing with my belly."  She shifted her body down the bed and held her massive gut.  I saw her ass and thighs didn't escape the growth, either, but they were overshadowed by her monumental belly.  Aroused, I shifted my erection into a more comfortable position.

 

"Come Jake," Marcy cooed, "I've missed you."  I tried to resist but I couldn't.  I found myself entranced.  I stripped off my clothing and climbed into bed on top of Marcy.  She was lying on her back with her belly spreading out and her heavy breasts resting on the bed to either side of her.  With her arms she lifted her belly back and exposed her pussy, ready and waiting.

 

"Fuck you're huge!" she cried as I thrusted deeply into her, propping myself atop her soft and inviting form.  My right hand explored her body, caressing it and grabbing handfuls of soft flesh.  My thrusts sent waves of rippling fat across her body.  Lost in the moment, I came into her with a shudder.

 

"Jake?" I heard from the doorway.  It was Stacy, and I was in for my fifth shock of the day.

 

Her breasts were so massive that they hung to her hips.  She had difficulty standing upright.

 

"Stacy, what happened?"

 

"We each took some pills, and - dear god you've got a huge cock - and...my tits...," she trailed off as she approached the bed.  A glazed look took over her face, and I could feel the same come over me.  I had a clouded thought about phermones but lost it as she neared.  Her tits were so big, with massive thick nipples, that I couldn't concentrate. Her ass flared out invitingly.  She pushed me back onto the bed next to Marcy, her gigantic bosom pressed between us.  She slipped me into her pussy and slowly pushed herself down.  She gasped.  Stacy's cleavage was pressed up into my face even as I felt the bottom of her tits near my hips with my hands.  Marcy, now kneeling next to us, began to play with Stacy's fat nipple,  Marcy's fat belly hanging to the bed and spreading outwards across the sheets.  Stacy's slow rhythmic thrusts began to quicken, and her breath grew more laboured.  I ran my hands across her body and the expanse of her breasts and thrusted in unison.  Stacy sat back and, with a cry of delight, she came.  Her gigantic tits rested upon my stomach.  The sight and weight of those breasts sent me over the edge and I came with a final thrust.

 

We separated and the three of us laid back on the bed.  Stacy's tits flowed over her arms and rested against me on my right, with Marcy's belly pressing against my left.

 

"As I was saying," Stacy began after catching her breath, "We found your pill stash in your backpack and took them.  We couldn't resist having some.  But then the changes started happening. I stopped taking them, and Marcy tried, but they are addictive!  I resisted, even as my tits grew so large that they rest on my lap.  But I want one so bad right now."

 

"I couldn't help myself," said Marcy, "I've never felt so good in my life.  I'm fucking huge right now, and I love it!  I just want to get bigger and bigger!  I...I've been getting more pills from Tara."

 

"Oh Marcy," said Stacy.

 

"Yeah, I grew, too," I said, "My dick, when this all started, was only 6 inches long and now it's nearly 15.  Plus, my muscles are bigger, and I'm taller, too."

 

"We could tell," Stacy said.

 

"Can I join in the fun?" Tara ducked under the door frame, her towering body nearly reaching the ceiling.  She might be even taller now.  She popped a pill on her way in.

 

"Tara won't stop taking them," said Stacy as Tara approached the bed.  Tara's pendulous tits swayed mesmerizingly from atop their high perch.  They seemed to swell.

 

"Oh come off it Stacy!  This is incredible!  I'm a goddess and I'm not giving that up!"

 

"You're a giantess Tara!  You've got to stop now before it's too late!"

 

"Oh pish posh!  Hey stud, come with me."  Tara lifted me out of bed.  Her strength seemed to have grown with her size as she pulled me up from the bed.  She WAS taller.  Whereas before in the entrance my head came to her chin, it now only came to her shoulders.  She was in the vicinity of 7'.

 

She crouched down before me, bent down and took my dick into her mouth.  I had a raging hard-on.  Just before I came she stopped.  Pushing me onto the bed while Stacy and Marcy watched, Tara turned herself around and lowered her ass into my lap, plunging my dick deep into her snatch.  Instinctively I grabbed her hips.  She began riding my shaft hard, and, keyed up as I was from her blowjob, I came into her.  She continued to thrust.  Incredibly, I felt her hips widen in my hands!  She was growing right in my lap!  Harder and harder she slammed into me, growing taller by the minute.  I came a second time when she gasped with her own mighty orgasm.  She fell to the floor, sated.

 

I got up and put on my clothes.  Tara was holding the bottle of pills in her hand.  Suddenly, I launched myself at the pills and grabbed them.  Struggling with me, Tara tried to open the bottle but I was still stronger than her and was able to wrestle the pill bottle out of her hands.  She tried to catch me, but her height proved to be too much of a hinderance and I slipped out of the room.

 

"I'll be back!" I yelled as I left the house.  Tara's massive naked frame was left standing just inside the door.  She was head and shoulders taller than it.  She slammed the door as I drove off.

 

I counted the pills from the second bottle.  For a four weeks supply I should have received 56 pills.  There were only 11 left.  I gathered them up and rushed to the lab, hoping that Trent was there.

 

Luckily, he was.  I explained the situation to him while he just sat and listened.  I told him about the drug trial, Yiroflex, my dick, Chelsea's weightgain, Katie's muscle growth, Stacy's tits, Marcy's fat and Tara's height.  Finally, I finished with the additive properties.  Then waited.

 

"You're full of shit," he said simply.

 

I stood there stunned.

 

"I mean, c'mon!  The stuff you talk about is theoretical at best!" he insisted.  Fuck it.  I dropped my pants.

 

It was his turn to be stunned.

 

"Holy shit!" he exclaimed as I did my pants back up.  "Holyshitholyshitholyshit."

 

Trent started pacing around the room.

 

"I can run a chemical analysis, and then study the composition of the drug.  Oh, and I need a blood, urine and stool sample," he fired off in rapid succession, "This is incredible."

 

"Can you fix it?" I asked.

 

"Fix what?  I doubt it," he replied, "I mean, it's like something in the drug triggered something in the body.  The body responded with targeted growth, it seems.  Probably permanent."

 

We gathered the samples for him, and I left a bunch of the pills with him.  I wanted to leave them all but he cautioned me that there will probably be withdrawal effects.  I have to ween myself off them.

 

"Start with one a day and then slowly work your way down," he advised, "And check up on those girls you mentioned.  It's likely that they overdosed on the drug and they may need medical attention.  I'm going to do my analysis as fast as I can, but I can't promise anything.  I need you to talk with their doctors on your next appointment, too.  I need data."

 

"Thanks Trent, I owe you," I replied as I left the lab.

 

"And no more sex!" he yelled after me.  Easier said than done.

 

I decided to check up on Chelsea.  She took a full load from me just after I downed five pills.  But first, a shower.

 

I stripped out of my clothes when I got home and dumped them in the laundry basket.  I reeked of sex.  Plus, my underwear is really confining.  I stopped to admire myself in the mirror.  I was looking good.  My dick was especially impressive.  My balls, too, were quite big now.  I worked up an erection just to see it.  A massive rod juted out from my crotch, thick as my forearm and nearly as long.  It was huge.  For a lark, I measured again.  15.25".  I HAD grown.  Measuring width came back just shy of 8".

 

I showered, cleaned up and decided to go to Chelsea's.  Last time I saw her she was about 270 lbs, pearshaped with disproportionately large tits.  Was she even bigger now?  My dick stirred at the thought.  'No sex, Jake!' I admonished myself.

 

I knocked.  "Chelsea?"

 

"Jake!" I heard an excited cry from inside.  The door opened to reveal my final shock of the day.

 

Chelsea stood before me in nothing but a t-shirt and panties.  Both were far too small.  Her flesh buldged out from under her shirt, forming an apron that rested upon thunderous thighs.  Pendulous tits hung to her waist beneath the shirt, their shape clearly outlined.  Her panties dug deep into her fleshy hips, and strained to cover her gigantic ass.

 

Suddenly Chelsea grabbed my shirt and pulled me inside her apartment.  She enveloped me in a squishy hug.

 

"I've been wanting to see you all day!" she exclaimed, "Those pills are something else! I'm fucking huge!"

 

"Umm...yeah," I didn't know what else to say.

 

"Yeah!  I don't know what's going on, but I've gained like 40 lbs today!  I can't stop eating," she exclaimed, "I think I was meant to be a fat girl, you know?  Because I feel good!"

 

Pizza boxes and fast food bags littered her dorm room.  She must have been eating non-stop all day.

 

"About those pills...," I explained to Chelsea the whole deal.  Well, I left out the other girls.  She seemed to take it in stride.

 

"Well, something was going on," she said, "No one sports a foot long dick."

 

"About that..."

 

"Hmmm?" she inquired with a look.

 

"Oh nothing," I said quickly.

 

"Oh, I bet 'nothing'!" she said with a devilish smile.  I was taken by surprise again when she bodily tossed me onto the bed and jumped on top of me.  Soon my pants were undone and my dick was out.

 

"Holy shit you got big!"

 

"I know!" was all I could say, "I took 5 pills last night and grew like crazy!"

 

"Ha! Your math was off.  You only had 3 that night.  I took 2 myself, and pocketed another 3," she stated, "I took them over the course of the day today."  She leaned back and patted her sizeable belly and hefted her massive jugs.  "I like the results."

 

I got hard at the sight of her above me.

 

"Mmmm, you like it, too," she cooed as she felt me rise against her ass.  She slipped down my body and began an expert blowjob.  She could barely fit her lips around my head.  She licked and stroked me bringing me to the brink of a climax.  She then stopped to show me the pill she had in her mouth, playing with it with her tongue, smile on her face.  She had been sucking my cock with that in her mouth the whole time.  My shock lasted only a second because she went back to sucking my cock.  I exploded in her mouth.

 

"Now for some big cock sex," she said and climbed on top of me.  She slipped my still hard cock into her.

 

Like Tara before her, the sudden influx of the drug into her system jump started her growth.  I could feel her swell ever so slightly on top of me.  Pounds of flesh slowly built up while we increased the rhythm.  My dick was on fire.  I swear I could feel it grow inside of her.  Chelsea leaned forward and kissed me, her tits pushing into my body.  She pushed her tongue in my mouth and delivered yet another pill.  Giving in, I swallowed.  Chelsea was a cockhound.

 

Deep into the night we fucked, each of us popping more pills.  I had no idea how addicted I had become but the sex was ecstasy.

 

I awoke with a splitting headache next to Chelsea.  My fat dick hung heavily over my hip, touching the bed on the other side.  Fuck that was big.  Groggily I swung my legs over the edge, careful not to sit on my poolball-sized balls.  My dick flopped over the edge and nearly reached the floor of the low bed.  I stood up, my cock dangling close to my knees.  It was at least a foot long, soft.  I was scared to know how big it was hard.

 

Chelsea, as I half-expected, had grown, too.  She was lying on her stomach, still sleeping.  Her fat ass spread across most of the bed, her hips more than three feet across.  Thighs bigger around than me were touching nearly to her knees, even though she had them spread eagle.  Even her calves were fat.  She was probably 400 lbs, maybe more.

 

A definitive ridge of fat formed at her lower back.  Her waist, though proportionately narrower, was still huge, and judging by the way her ass was propped up, her belly had grown, too.  One fat arm was draped across the pillow, with some of the biggest Oprah Winfrey's I have ever seen.  Her right breast stuck out from underneath her - and the sucker was huge, maybe as big as Stacy's.  It didn't look so out of place on Chelsea.

 

I laid low that day and the next, eagerly awaiting my appointment with Yiroflex.  My dick, which was 16.25" long and 8.5" around hard Monday morning, had slowly grown to 17.5" by 9" by Tuesday afternoon.  Was this the result of Chelsea's pillsoaked blowjob?

 

A quick text update with Stacy confirmed that the latest round of sex with caused another round of growth.  Her tits were so large that they took up her lap and hung halfway down her thigh when she stood up.  Her ass, which she lamented used to be small and tight, was a verified booty, 48" around, jiggly and soft.

 

Marcy continued to grow fatter.  Her ass and thighs had begun to catch up with her belly but it was still oversized.  She was 457 lbs.

 

Tara topped out at 7'3" and has seemed to stop growing taller.  She was suffering from withdrawal pangs, and was having trouble keeping down food.  Her tits were still growing, though.

 

I hadn't heard from Katie, nor from Trent.

 

My visit to Yiroflex was that afternoon.  When I pulled up to the clinic, something didn't look right.  The sign was taken down and all the lights were out.  I got out of my car and walked to the door.  It was locked.  Peering in the window, I could see that the clinic was completely empty.  No chairs, no desks, no posters on the wall - no signs of life at all.  What the fuck?

 

I grabbed my cell phone and dialed the toll-free Yiroflex number.  'The number you have dialed is no longer in service.  Please hang up and try again.'  What's going on?

 

Giving up with the clinic, I drove back home.  Hoping on my computer, I entered the web address.  A Yiroflex splash page came up.  I entered the site and started poking around.  Digging a little deeper, though, all of the links were broken, the email addresses bounced and some of the pages were simply blank!  I was getting worried.

 

I googled Yiroflex. 'Did you mean Giroflex?'. Nothing.

 

My only hope now was Trent.  And he wasn't returning my calls.

 

I eased off on the pills.  I took only 1 a day.  I still had 10 left.

 

I tried to be inconspicuous over the next couple of days, but my reputation - or, I should say, that of my monster dick - got around.  Girls would stare at my crotch - hiding the buldge of a 12 inch flaccid dick with two poolball-sized balls was a hard thing to do.  My hormones were still on overdrive, and I would get erections at the slightest provocation.  I was accosted more than once - in elevators, in nooks, in empty hallways, in the library, in bathrooms - and always my dick would swell, harden and make its way down my pants leg.  The more adventurous would even take it out.  I was so horny I didn't resist.  Between Wednesday and Friday, I received no less than 6 blowjobs by random girls and offers of sex by at least a dozen.  I had 4 booty calls on Thursday alone.

 

I'd fuck these girls like an animal, plunging my now 19 inch cock deep into their pussies.  Most couldn't take it all in.  I'd cum incredible amounts and rarely ran dry.  In the back of my mind I wondered if my prostate had grown, too.

 

Saturday morning I awoke with a raging hardon.  Curious, I measured myself: 20.75" by 11.5".  I decided to cut back to half a pill a day.  I wasn't suffering from any serious withdrawal symptoms.

 

I saw Stacy around campus.  Well, everyone did.  Her massive tits gave the appearance that she was smuggling beanbag chairs under her shirt, but the two feet of exposed cleavage belied that.  She cornered me in the hallway and insisted that I take her back to my room.  Who could say no to that?  I watched Stacy walk ahead of me and was enchanted by the sway of her breasts.

 

She took off her shirt and freed her tits from a gigantic bra that was still 10 sizes too small.  Massive tits flopped against her thighs.  I got naked, my 20" erection ready.  Stacy bent over the bed, her heavy breasts pooling across the sheets, and propped her booty in the air.  I grabbed my cock and rubbed my head against her moist pussy.  My girth stretched her wide as I slowly slid inside of her. Stacy moaned in pleasure, grasping the sheets.  I worked myself deeper with each thrust, amazingly working over 15 inches of cock into her.

 

My rhythm increased.  Stacy moaned in pleasure and pain.  My fingers dug into her fleshy hips and I came deep inside her, thrusting nearly to the hilt.  Stacy cried out and shuddered with her own orgasm.  She collapsed onto her giant tits.

 

We cleaned up and Stacy went on her way, promising to "visit" again.

 

I had a more visitors throughout the day, some repeats, including one from Chelsea.  She loved my new cock, and I loved her 400 lb body.  One girl, Tina, came back twice.  I fucked her once on Wednesday and I remembered her as an average looking girl, B-cups, with big nipples.  By Saturday night, she had already grown to a C-cup, and was generally thicker.  I guess I was still potent.

 

My room was like a revolving door all next week.  I was having sex 5 to 10 times a day.  New girls and repeats, with the repeats exhibiting new growing bodies that drove me wild.  A lot put on weight, as much as 20 lbs, and most had their tits grow.  Word spread about my "magic cock", and it was all I could do to have a spare moment.

 

I downed my last half-pill on Friday, hoping my reduced regiment had sufficed in preventing severe withdrawal symptoms.  My dick was 22.25" by 12.25" by that time, 13" long flaccid.  Only Tara could take me to the hilt, though Stacy gave a tremendous tittyfuck.  Tara's tits had stop growing to rest at not-quite soccer ball sized.  Marcy's accelerated weightgain stopped by the time she hit 531 lbs.  Her big round belly hung to her knees and supported big floppy H-cup breasts.  She took delight in hefting her massive gut onto tables and watching the fat pool and spread.  Chelsea was officially up to 427 lbs of pearshaped succulence, sporting pendulous K-cup breasts bigger than my head.  Her belly apron hung low, and her hips barely fit through most doors.

 

I finally got a call from Trent the next Saturday.  He asked me to come over.  I wasn't ready for what I saw.

 

"I took them...I took them all," he stammered, lowering his massive bulk onto his couch.  Trent had transformed from the lanky whip-thin nerd I knew him as to a fat but muscled mass.  He had a big hairy gut that refused to stay covered, but huge muscled arm and tree-trunk legs.  Between them sat a big fat cock and large balls stuffed uncomfortably into a pair of boxer-briefs.

 

"I was so jealous, and so intrigued that I tried one right away.  And then another," he continued, "I had 5 that day, and woke to a beefier body with a dick 10" long.  I took the rest that day.  I shouldn't have.  I've been growing steadily ever since..."

 

We chatted a bit, but there wasn't much we could do.  He confided in me that his dick was now 19" long, and a whopping 18" around.  His balls were like two oversized grapefruits.  He weighed 470 lbs.  He hadn't left his home since it happened.  He was freakishly huge, but I guess it could be worse.  I brought him a pair of XXXL sweatpants and t-shirt so that he could at least leave the house.

 

The pills were gone, Yiroflex vanished - probably to prey on a new unsuspecting public under a new name - and slowly the growth stopped for all of us. 

 

By the time I stopped growing a few months later I was 6'2", 195 lbs, with a 23.5" by 12.75" dick and orange sized balls.  I struck an impressive figure.

 

Stacy quit school and moved to L.A. to become an actress, though I wasn't surprised to find that she had become an internet pornstar sensation just weeks later.

 

Tara got on with her life and started dating college basketball players, where her height didn't seem so extreme.  I didn't see much of her.

 

Marcy was 562 lbs the last time we measured, and was happy as a clam.  She found herself a rich FA boyfriend and spent her days eating in luxury.  They got married and moved to Colorado shortly thereafter.

 

Katie, whom I barely kept in contact, became a full-on gym rat.  She won the local competitive female bodybuilder title and I think went on to compete in Ms. Olympia.  Not sure how she did, but probably pretty good.  I think she worked at a gym now.

 

Trent got on with his life, and fell in love with a nice girl who called him her "big honey bear."  Good for him.  We stayed good friends.

 

A lot of the other girls I banged sported modest growth - in comparison, at least - though Tina swelled to a 200 lb girl with G-cups.  I thought she was hot.  Girls would still wink at me in the halls, but I would let anything happen.

 

Chelsea and I started dating, ending my rampant sex life - thank god.  My sex drive finally cooled down after a few weeks to somewhat of a normal level, as the last of the drug cleared my system.  Chelsea plateaued around 490 lbs, and her jiggly fat body never failed to arouse me.  She claimed she was satisfied with my dick size, but sometimes I got the feeling that she wished I had grown that final half inch to a full two feet long.  Oh well.  I just shook my head and laughed.  She did miss the way her body used to grow bigger and bigger in a matter of days, and I noticed that she started to pack away increasing amounts of food.  We'll see where this leads, but that's for another time.

 

THE END
