Growth

[darlene990988]

Luke waited patiently for the rest of the people seated in his row to file out. It had been a long class, and he didn't mind stretching for a moment before heading out for the weekend. He began idly flipping through different apps on his phone before gathering his things and strapping on his backpack. As he was heading towards the exit, he heard the professor calling out to him several rows down the lecture hall.

"Luke, I've been meaning to remind you that I've finished your letter of recommendation."

Luke was very close to Professor Karden, who was more than just a mentor to him. He had guided most of Luke's undergraduate career, and now he was essential to Luke's grad school application process. While he was an up and coming prodigy in the burgeoning field of biophysics, he was a bit lazy when it came to things like filling out forms and faxing in documents. Without the guidance of his his Professor, he likely would not have applied to any programs at all.

"Thanks Jim, now that I have three I suppose I should finish the USC application. Everything else is taken care of though..."

James Karden continued making his way up the stairs to had a manila envelope to Luke.

"You know, if I had the funding I'd gladly keep you on here. But you're off to bigger and better things I suppose" he said with a glint in his eye.
He placed his hand on Luke's shoulder and patted him on the back, and for the first time it occurred to Luke how much he would miss the familiarity of his old campus. There was something especially wistful about Professor Karden, which signaled to Luke that he was aware of the impending end to their relationship as well. Luke, at a modest 5'8" in height, looked up into the Professor's eyes and contemplated expressing his gratitude in a meaningful way. He couldn't find the words, and simply uttered a quick thanks and changed the subject.
-------------------
Molly hadn't heard from Luke all day, so she sent him a text message.

"Still at the lab?"

Molly herself had just gotten back from her own labwork on the other side of town. She knew his position as a research assistant could have long hours sometimes, but it was unusual for him to not tell her that he would be home a little later than normal. He had always been extremely considerate of her, ever since they had first met. When Molly was fourteen, she moved from Missouri to Los Angeles in the middle of the school year. Such a drastic change in setting would have been hard on any awkward teen, but it was especially troubling for the large sized Molly. Even as an eighth grader she was already 5'8", and her entire life she had been extremely overweight. Not only did she have to deal with being "the new kid," but she stood out so much that the other kids couldn't possibly keep themselves from ostracizing her. She didn't have a single friend for the first two months at her new school, until she met Luke. Like her, Luke had transferred in the middle of the school year. Also like her, his father was in the advertising business. Once they were assigned as lab partners, they found comfort in each other's understanding of what it felt like to be a bit outcast. They became best friends, and remained so even in the following years after they had finally assimilated into other social circles. When they saw less of each other due to more time spent with other friends and activities, it instantly became clear to both of them that they had feelings for each other beyond mere friendship. In a very natural and organic way, they moved on to dating, and now in their final year of college they had begun to discuss marriage. Molly's phone chimed.

"It worked. We can test it tonight."

She felt a little light headed when she read the text. Her entire 5'9, three hundred pound frame slumped itself down onto the bed. A wave of warmth washed over her massive body.

Luke walked up to the dorm entrance to find Molly sitting at the foot of the stairs waiting for him. They spent hours discussing the breakthrough that their combined efforts had accomplished, finally agreeing that it was ready for human testing.

"It just doesn't seem real" Molly said while taking a long sip of her beer at the kitchen counter in the commons while sitting on a chair she had turned backwards. She stared ahead aimlessly, as if looking at something a thousand miles away.

Jim set his bottle down and just let the moment soak in. He felt so triumphant, and his enjoyment of every little aspect of life was almost overwhelming. The ice cold beer, the light breeze of the fan, the jazz music wafting out of a radio in the other room, his loving girlfriend sharing in the moment...

He glanced over at her and was overcome with emotion. Despite her enormity, Molly's body had an extremely alluring form. She didn't have a shapeless stomach that folded over itself or lingering bags of fat off of her arms. In fact, her stomach had no overhang at all. Of course it protruded, but it didn't sag under the gravity of itself. The only way to describe her midsection was that it was almost impossibly thick. She still had a nearly ideal waist to hip ratio and was generally very flat from the front, but her depth was expansive. Her narrow shoulder bones gave way to volleyball sized breasts. They were so soft that the near underarm would naturally dimple whenever she laid on her side and let one breast settle on top of the other. Her ribcage narrowed down into her thick midsection before spreading out into her gargantuan yet perfectly smooth thighs, and down into her somewhat shapely calves. The most interesting aspect of her appearance was the slimness of her face, which somehow had never seemed to gain weight with the rest of her. Equally as contrasting were her dainty hands and feet. Her leg sloped down into a foot that was only a size 5, and when she placed her tiny palms flat on her thighs it looked like a single pea on an entire plate. She continued staring out the window silently as her sparkling blue eyes gently closed.

Luke walked up behind her and began running his fingers through her hair. She turned around and stood up to her full height, her body eclipsing his in the night air. She leaned down to kiss him, then lifted him up as he attempted to get a grip on her torso. Her soft breasts spread out on his thin chest, and they held hands while walking up the stairs to Luke's room together.

Luke climbed on top of her naked body and began a slow, rhythmic grind after entering her. She wrapped her arms around him and he pushed down with all the force his 140 pounds could muster. During a break, he got up and removed two vials from his jacket on the floor.

"Me or you?"

Her eyes told him all he needed to know, and he walked over to pour the contents down her throat. They resumed making love, but this time Molly had carefully positioned herself on top. The pressure bouncing on top of Luke was comforting, but he knew the time was coming. With Molly still straddling him, he leaned back on his shoulders and began to massage Molly's areola. It had already begun to look swollen, and soon a small discharge came out of it. Luke attached his mouth to it and dutifully siphoned off whatever was presented to him. Slowly but surely, Molly was becoming lighter. He could feel the changes occurring as each minute passed, but he couldn't see anything for sure yet. He drank, and drank, and drank as the night waned on. It was a nearly transparent liquid, so it went down easily and he had no signs of feeling bloated. However, it seemed that they were both becoming extremely light headed. Nearly intoxicated from the entire context of the situation, they breathlessly rolled apart and passed out for the night.
------------------------------------------
Luke awoke first the next morning. He felt groggy, but forced himself out of bed in hopes of examining what had happened to Molly. She was laying naked on top of the bed without anything covering her, and she was a sight to behold. Her thick proportions remained, but she had obviously lost a significant amount of weight. She had a healthy, natural glow to her lightly tanned skin. She oozed fertility, like a rushing torrent of sensual appeal. Her breasts were perfectly proportioned to her new smaller build, now "only" the size of cantaloupes with flawless shapeliness. Her now tiny yet still soft waist gave her an exaggerated hourglass appearance, with her precisely tightened skin leading down to her lightly haired vagina. Luke almost felt perverse to be observing it so intensely, but it seemed to be twitching intermittently. Molly seemed to have a satisfied expression on her sleepy face, and finally Luke could not help himself. He kneeled down and began pecking it with tender kisses, eventually inserting his tongue as Molly slowly woke up. She encouraged his actions, but quickly recalled the events that occurred the night before. She shot out of bed to examine herself in the mirror, and tears welled up in her eyes as her hands probed over her new body.

Luke walked in and held her, not a word needing to be said. She knew that he had found her attractive before. She knew that even if he hadn't, that their long built bond was so strong that neither of them could have possibly cared less what the other had looked like. He knew that she had struggled for many years with her weight and ultimately accepted it as something that she couldn't change, but that she had always secretly hoped to be smaller. They continued holding each other, and for the first time in his life Luke could fit his arms around her while they embraced. They swayed in the silence for a moment before Luke broke away.

"Wait here."

He sheepishly returned with a doctor's scale.

"I figured, well you know, maybe we could use this."

After fiddling with the measuring stick and confirming that she was still 5'9, they weighed her to discover that she was now 170 pounds.

"As we know, the recipient of the extracted nutrients has a much slower reaction. I still want to start the log now though."

While Luke's changes were not nearly as drastic as Molly's, he had still gained an inch in height and put on a few pounds. He genuinely, in his entire life, had never given much thought to his appearance outside of maintaining basic presentability. Now though, he was a little turned on at the thought of finally filling out in a second puberty of sorts.

As the days stretched on, Luke's steady growth continued while Molly's last few minimal changes finally tapered off. She had settled at a weight of 165 pounds, without an ounce of sagging flesh. Every curve was seemingly custom made to attract the male eye; and while completely smooth and pleasurable to the touch, she had a light smattering of muscle tone in her long formed limbs. Though her body had stopped transforming, she continued producing meager but steady amounts of the liquid from her breasts that provided the catalyst for Luke's growth. While he never got a portion as large as he had the first night, Luke continued drinking from Molly steadily. His size increases seemed to come in pulses - one day he would be slightly taller with a beer gut from some new pounds, and the next he would have grown a solid inch or so with some caked on layers of muscle.

By the time Luke's acceptance letter to USC's graduate program had arrived, he was 6'2 and 180 pounds. His feet, which had previously been narrow and barely longer than Molly's were now certifiably jumbo at a thick size 13. Molly's feet looked particularly funny next to them, and she delighted in holding his leg into the air while placing both of her feet onto his one tremendous sole. Since his growth had remained constant, he had been hesitant to completely upgrade his wardrobe. Cheap athletic shorts lasted only a week or so before they would begin clinging to his expanding body. Old t-shirts would occasionally rip at the seems, much to the amusement of Molly.
As they had more and more time with the semester winding down, Molly and Luke were having sex around the clock- with each session being accompanied by more breast emissions for Luke to consume. On certain days after a growth spurt, Luke's sex drive would be insatiable. Whenever he became taller, he would look incredibly lean. Each individual muscle would pop, and Molly enjoyed tracing her fingers between the separation of each grouping. For Molly's part, she was essentially making love with a different person each day. Sometimes Luke would be a bit more burly and bulky in what she called lumberjack mode, and then within a few days he would be some sort of Olympic swimmer on top of her. His genitals had kept up with the rest of his body as well, and each day she would adjust to a penis that was imperceptibly larger than the day before. In just a few weeks, it had gone from an average 5" to a towering 8", with a near muscular looking 6.5" girth. A year ago, Molly could never have pictured herself caring about something like that at all. Now that she had it though, it was almost entrancing. She would spend hours attending to it, playing with it, suckling while fondling his thick scrotum.

On the weekends they would live in the bed, barely getting up at all. Humping, drinking, cuddling, caressing, growing...
------------------------------------------------------
By the time classes ended, Luke stood at 6'4 and weighed 220 pounds. He woke up on graduation day and wiped the sleep away from his eyes. He gazed down at his huge feet hanging off the bed, then rolled out from under the covers. He still had a few hours to kill before needing to head to the events center for his commencement ceremony, so he decided to get some coffee from the campus general store. Few people had opted to extend their dorm lease through the summer as he had, so he figured there wouldn't be many people still hanging around. This meant that he wouldn't have to struggle to cover himself up, as he hadn't been clothes shopping in a while. He had slept in the nude and decided to slip on some basketball shorts that clung to him like a speedo. He supposed if anyone saw him they might pass as short marathon style shorts, so they might think that he had been out jogging. He pulled on a white t-shirt and inspected himself in the mirror. The sleeves of the t-shirt barely made it to his triceps due to being stretched out by his immense shoulders. He was carrying a little extra weight today, so instead of being cut and vascular his 18" biceps looked extremely smooth and mounded. Some of his fuzzy abs peeked out of the bottom of the shirt, each brick thickly defined and separated but covered in a thin layer of fat. His masculine aura was almost palpable. He decided the shirt looked too bizarre, so he strained a little to stretch upward and peel it off. In the process, his whopping package had flopped out of the bottom of his shorts. His bulge hadn't been obscenely noticeable due to the shorts being blacked, but he certainly couldn't be walking around with parts flopping out and becoming exposed. He tucked himself back in and improvised, going outside barefoot with a towel over his shoulder to feign as if he had just come from swimming. When leaving the single door back exit from his dorm building, he had to turn sideways to accommodate the width of his upper body. It felt a bit foreign to be walking barefoot on the familiar concrete path to the middle of the student center, but in a way it was liberating. He padded along without bumping into anyone else, and he wondered why he was so worried at being underdressed for a 7 A.M. walk to the coffee cart.

The girl working at the coffee cart was bent over and pulling out some napkins to set up for the day. She turned around to plug in a few things to the power strip and turned around to find herself eye level with a husky, swooping pectoral right in her face. Her eyes darted side to side, and the sun happened to be hitting his vast bulk in a way that highlighted the light dusting of blonde hair swirling around his chest. Her immediate instinct was to step back because it felt like he was way too close. However, she realized that he was a normal distance away from her on the other side of the cart - he was just so built that the sides of his body expanded farther in her field of view than she thought possible. After ordering a cup of black coffee, she blushed as he ran his hands over his stubbled face while giving her a friendly smile. She stood there with her underwear feeling moist, in awe as each of his muscular bowling ball sized ass cheeks began to slowly creep out of the top of his waistband as he walked away.
--------------------------------
During the summer, Luke and Molly didn't have a single obligation. Luke's dorm room was paid off until the end of summer, and his first graduate program grant check had already arrived to cover their expenses. Since they mostly hung around the house all day, they didn't bother with clothing. They were so in tune with each other sexually, and their desire for each other had only increased over time. Luke was now hulking around at six feet, five and a half inches tall - at a weight of 250 pounds. Luke would greedily drink down whatever liquid Molly was able to produce, but each passing day had smaller and smaller emissions. Furthermore, the potency of her production seemed to be waning. Luke no longer had individual spurts, but rather just steady increases in size. His muscles remained large and hard, but he no longer had periods of extreme leanness. He was constantly padded with about 14% bodyfat, which was fine by the both of them anyway. This way he felt more natural, like he was inherently meant to be big instead of the "achieved" look that accompanied his bodybuilder-like periods of leanness. He loved the equilibrium he has reached - he had a gut, but it wasn't fat and his dense abdominal muscles were visible underneath. He was still trim and his overall body shape was that of an inverted pyramid, and he felt more comfortable with this more rugged build. Molly had expressed explicit approval of this form as well, and on one occasion had uttered "there's something about the weight of a big man pressing down on you that makes you forget all your troubles."
After deciding that they needed to get out of the house, they agreed on heading to the beach. While it wasn't said out loud, they both knew that there would be a bit of exhibitionism going on. They were too shy to acknowledge it, but they both knew that plenty of heads would be turning. Since Luke would be leaving for the weekend to attend some preliminary meetings at USC for the weekend, they decided to make a nice picnic as a mini-sendoff for him. As a surprise, Molly had also picked up a few new items for Luke while out shopping. A generously sized tank top, some nice baggy board shorts, and, best of all, a new wetsuit. He had always been an avid surfer, and she thought it would be funny to see him attempt it at his new size. For herself, she bought a neon orange bikini that was barely able to contain her overflowing chest. She put a thin white t-shirt on over it, with a pair of boyshorts that just barely covered the bottom curve of her behind. Luke tossed on his new stuff and slipped into a pair of crushed size 16 flip flops, and they headed off to the beach.

They spent the day having fun in the sun, and eventually settled down to have some of the food they had packed. Molly set a lantern out on their blanket and popped a bottle of wine while Luke pulled down some of his wetsuit. His arms were now bare and the top of the suit rolled up under the shelf at the bottom of his pecs. The lines of the grey and black wetsuit augmented the V shape of his upper body, drawing her attention to just how much he tapered down at the waist. When he turned sideways to bend over and grab a towel, she couldn't help but notice his gargantuan ass sticking out to the side. She almost wanted to bite the neoprene fabric stretched over it so tightly.

"You know, it's kind of funny to think that I used to be bigger than you" she mused.

He stood back up with a grin while running his hands through his hair, which caused the suit to shift a bit and cling halfway down his colossal lats. She couldn't take it anymore, and reached up to massage them while rolling the rest of his suit down. She aggressively took the whole thing off completely, and with a feigned yelp he quickly dove under their blanket. It was becoming dark, but there were still other groups smattered around the beach and a few bonfires were starting. She joined him under the blanket, and they looked around somewhat casually. Nobody seemed to be paying them any attention, and they were fairly well covered by the blanket. He stayed next to her, but swung one of his heavy legs over her to get himself closer. She began lovingly tugging on his 10" penis, which had recently become just shy of 7" around. He inserted two meaty fingers into her while slowly massaging, and they reveled in their hidden tawdriness. As it became darker, they became more bold, and he rolled over on top of her. She was moving her petite hands all over his musculature, eventually setting on cupping as much as she could of each substantial ass cheek she could while pulling him deeper and deeper into him. He bucked a few more times as they came simultaneously, then rolled off with a satisfied sigh. Her face was flush and she had a contented smirk while pouring two more glasses of wine.

"I think I'd like to go for a quick rinse before the water gets too cold."

As she slid her bikini bottom back on and walked into the water, Luke removed a small vial of liquid and poured half of it into her wine glass. They sipped some more wine as the sun set, then decided to go at it again in the moonlight. She spread her legs wide as he penetrated as deeply as possible, the blanket now bunched around the small of his back and draping over them. He craned his corded neck down to begin sucking the release from Molly's nipples, and he hoped that she didn't realize that she was leaking much more than usual. A little too lost in the moment, they didn't notice the approaching beach patrol officer.

The patrolman coughed awkwardly, and Molly and Luke froze in embarrassment.

"You know, you can't do that here...technically I should issue some sort of citation but just cut it out."

A bit buzzed and glad to not be in any trouble, they both hopped to their feet to thank him while trying to cover up as much of their nudity as they could. Molly was roughly the same height as him, and outweighed him by a fair amount. Luke extended his hand to the watchman in gratitude, and his hand completely disappeared while they shook. He couldn't believe that the gargantuan hand extended out into such a meaty forearm.

"So anyway...don't let me see, uh..."

Molly sensed the awe of the poor guy, and tied her bikini back on in a way that was perhaps a little too suggestive.

"Sorry officer, it won't happen again."

The straining fabric was readjusted as Molly cupped her breasts to straighten them out, and Luke's pendulous package visibly stirred in response while he looked away. The officer began to mutter something , but turned away with his tail between his legs.
--------------------------------------
Luke was ecstatic to see Molly for the first time in three days. He wasn't due home until later in the afternoon, but he decided to surprise her by heading straight to her place. The acute dose from the vial had given Luke another one of the old growth spurts, and he wondered how Molly would react. He rang the doorbell, and she opened it to see a gigantic form filling the entire door frame. Luke's face was hidden behind the top of the door frame. The tank top he was wearing was in complete disarray. The spaghetti straps were ready to snap across the expanse of his chest, while the bottom of the garment hung loosely from the cliff created by his depth. He ducked under the doorway and was shocked to see that Molly was changed. She had shrunk to 5'5", and had to weigh less than 100 pounds. She looked smaller than the upper part of his leg. They both stammered for a moment before thinking of what to say.

"Some kind of variation in the second dose..."

They began discussing what may have happened when Molly began kneading Tim's stomach. He had removed his tank top, and gawked at his new proportions. His adonis belt was cut and visible, but his smooth belly popped a bit. Unable to contain himself, Luke pulled down his shorts and let his now unworldly erection spring free. The fleshy palms of his broad hands pulled the back of her head closer, and she was able wrap her lips around the tip of his penis with both of them standing straight up. She gazed up at him lovingly as she struggled to keep any amount of him inside of her mouth. Close to losing it, Luke quickly reached into his bag on the table to pull out the half filled vial. He gulped it down, and his 4 inch testicles seemed to churn. As Molly began swallowing his release, her breasts began expanding....

Very nice (especially for a hetero story!) My only disappointment is not knowing how big Luke was in the very last section!

Mmm I love the few but fantastic hetero couple transformations that come around on the site. So much more fun to fantasize in my head Thank you for posting!

Hmmm, An interesting twist on the cum that makes you grow plot... At first I figured the that there was going to be a growth drug (for Luke) and a shrink drug (for Molly). But you wrote in "conservation of size function"; that is an interesting wrinkle, I must say... Luke's formula could be the basis for a new twist in guy on guy muscle theft stories... A really great revenge for guy's that are forced the suck their bully's cock.

But the end is a bit confusing... It sounds like right after Luke gives Molly her second dose, the one on the beach I get the impression Molly (or at least her breast) ballooned bigger. And then after Luke goes to USC she dwindles to a rather thin 5'5" 100lb over the three days Luke was at USC. If Luke wasn't with Molly to ingest her fluid he shouldn't grow. Logically Molly would shrink, but in Luke's absence the fluid (and possible growth) would be lost.

So, how did Luke get huge with out Molly's fluid and if he didn't want Molly to be as tiny as she got why give her the second dose in the first place.
