Centimeter by centimeter he watched his cock grow thicker, spreading Christa's cunt ever wider in its wake. Both of her hands came down to grip the base of his cock as she looked down in disbelief. At least six inches were outside of her now, and she had taken him nearly all the way before. Curt opened his eyes and stared in disbelief. He was growing even faster this time! His cumming continued to make him buck like a bronco as his shaft grew ever more horse-like. Thicker and longer -twined with huge, thick veins- his erection plowed into Christa's tight bush like a dog trying to fit into a rabbit hole.
"Ahhh! Curt! Omigod ... you're goin' too ... far!"
Drastically, Curt tried to pull himself out of Christa before he hurt her. Her moaning and bucking were intense and -just before he could- he felt himself hit a massive climax. Rigid, he watched as his cock rocketed upwards in size, spreading her cunt lips and making her squeal half in pain, half in ecstasy. His balls pumped and churned as they lay heavy on his thighs. In shock he looked at them, tangled in their mass of pubic hair. Each was larger than a large grapefruit! His shaft had to be at least three and a half inches across and nearly sixteen inches long! The spasm began to fade, but the tingling in his balls remained. Orgasm subsiding, Curt felt his body grow limp in its wake.
Slowly, Christa pulled off of him and slumped next to him on her bed.
His massive rod stood up from his midsection like a bent flagpole. Gobs of his cum dripped from Christa's stretched cunt as she panted for breath and rubbed her delicate hands over Curt's chest. Opening her eyes, she glanced at Curt's waist and shook her head slowly. "God, Curt... I don't believe it." She smiled, and nuzzled the smaller man's neck -her glistening breasts pressing against his chest. "Th' bigger th' better, I've always said... I don't think I've Ever been this turned-on!"
Curt returned her smile and kissed Christa gently on the cheek. He tenderly stroked her breasts, fingertips lingering on her aureoles and nipples. "Yeah, but any bigger and only a Clydesdale would be able to take all of me..."
Christa shrugged as she nestled into the size of Curt's body. "Maybe," she said conspiratorially, "that wouldn't be all that bad." With that cryptic remark, Christa closed her eyes and gently drifted off to an erotic sleep.
The next few days were difficult. Even when not erect, Curt's new endowments were extremely obvious. His penis hung all the way to his knees and was nearly as thick as a peppermill. Still, that was the least of his problems. It was possibly due to the extreme exposure his balls had been given to the original formula, but they'd been growing at an even faster rate than the rest of him. Each was the size of a grapefruit and always seemed to carry the tell-tale signs of that tingling sensation -together they spanned nearly a foot from side-to-side in front of his groin. It wasn't easy to conceal his massive endowments.
It also hadn't been easy to resist Christa's advancements. She was so turned on by his recent growth, he wasn't sure she would ever stop making him bigger. She'd offered to tit-fuck him if he ever got too big, and to masturbate him if it went much further beyond that. Curt had to admit, it was extremely tempting... But until he knew he could reverse the formula, he didn't dare give himself over to that temptation...
Not when the last growth spurt had so radically increased his size, and the tingle still hadn't gone away...!
Mostly, he got by during the next week by wearing no pants around his dorm room, but squeezing into a pair of Zubas whenever he had a class. Still, he got stares and more than a few proposals from some of the prettier women (and a few of the guys) in BioChem lab. Still, he'd almost had to cash in on a few of those "favors" to get help swiping the necessary compounds from the storage locker. Luckily, with his standing in class, it was easy to stay late "working" on a project and being allowed to "lock-up" after himself.
Now, after about a week, he thought he may have the solution.
The first chemical seemed to be stimulated by sexual arousal and semen production. In other words, the more he came, the bigger he got. Curt also thought that he may get bigger if his cock was in direct contact with a woman's vaginal juices. Why that would be the case was still a mystery to him ... in addition to the twin questions of where the extra mass had come from so quickly and why he could still get 16" erections as easily as 3 inches... Technically, the blood requirements would be too high, and he should've been getting light-headed.
His cursory examination of himself showed a development of muscle and ligament tissue along the length of his shaft, and that could account for his amazing erections, but he couldn't confirm it. Nonetheless, he thought as he looked at the light blue liquid, this seemed to be appropriate to reverse whatever effects had been caused by the original fluid. Christa wouldn't be happy, but he had to think of living a normal life rather than a horse-like stud! Still, it wouldn't hurt for one last time.
As Curt carefully turned off the Bunsen burner and went to sleep, he didn't notice the shadowed form slip in through his open window and walk slowly towards his desk...
Curt's balls still were tingling as he carefully got out of Christa's car at her parent's cabin on Lake Hutton. The sky was clear and the deeper blue that comes with Evening in Northern Minnesota; the reflection of the sun off the narrow stream that bubbled down the hill next to the cabin into the lake was enchanting. Christa was still somewhat down since he'd told her that he had developed the reverse formula and would use it after they had made out this last time. As she had said, she really liked men who were freakishly large...
Curt had just smiled past the word "freakishly" and let it go at that.
Christa opened the door to the family "hunting lodge" and set down the bag of groceries on the counter nearby. The place was huge. Curt let out a low whistle of breath as he surveyed the scene. At least ten trestle tables filled the room beyond the small kitchen in a grand hall that reminded him of Beowulf's "Herot". A small balcony ran around the room about a story overhead and numerous small doors led off from the main hall into the private bedrooms that filled this place. Christa hadn't been kidding when she'd told him her father had liked to hunt with a "few" friends every autumn.
The fact that this hunting lodge could house at least thirty men and their equipment was something she hadn't mentioned. Nearby, a wooden sign declared the room rates for the weekend during hunting season. Apparently, her father also made a tidy sum on the place too...
Christa smiled as she pulled out the jar of blue liquid that Curt had brought from his dorm room. It was more than twelve times what he needed, but it wasn't as concentrated as the original formula. He'd just have to keep adding it until he got it right. Christa shook her head.
"Y'know, guys all over the country would kill to have your problem; and you're going to give it all up..."
Curt shook his head with a crooked grin. "Well, if I get any bigger, I'll start having problems walking. The idea of being hung like the Eifel Tower may interest me, but not until I can get things under control!" He chuckled and started bringing in the suitcases from the porch. Christa simply grinned as she watched him work and the mass of his groin shift around in his pants.
Curt finished putting the suitcases in one bedroom and turned to join Christa back in the kitchen. She stood not far from him with her back to the broad double-doors. Curt started feeling nervous again. Sheesh! She was insatiable! Slowly, she pulled off her sweater revealing her massive, heavy assets. Slowly, she swung the doors shut behind her and sauntered towards Curt. Running her fingers along the side of his neck, she gently pushed him backwards towards the bed.
She shushed him with a single finger and kissed him lightly on the lips. "Shhh... If we're gonna make the most of this weekend, we're starting now..."
Slowly, Christa pushed him down, lay provocatively on top of Curt's body, and rested her ample breasts in his hands. Curt happily stroked and fondled them as Christa gently massaged Curt's 16-incher through the material of his jeans. Curt drew three rapid, deep breaths of shuddering pleasure as Christa's talented fingers probed his grapefruit-sized balls. As she bent her face down to plant her lips on his, she deftly undid his button-fly Zubas and pulled down his underwear.
At first, his massive organ got caught in the elastic binder, making him wince slightly. Christa smiled at his expression and pulled back from his eager hands to watch what she was doing more carefully. Gently, she licked his engorged knob and pulled his pants off the rest of his legs. More quickly then, she removed his shirt and the rest of her own clothing so the two rested naked on the king-sized bed. Curt's enormous flagpole stood at attention to Christa's ministrations as she licked his knob and repeatedly squeezed his semen-heavy balls. The tingle, which had been there constantly since the last time they made out, started to increase even more.
Slowly though, Christa pulled her mouth away from his cock and slowly rubbed it down her naked chest, between her breasts and gradually across her flat, tight belly. Rising to her knees, she slowly lowered herself down around the monster organ with a look of ecstatic glee on her face. Curt couldn't say anything. It felt too good. He just hoped she'd be able to handle what he became next...
Grinding slowly against her cunt, Curt watched as she devoured inch after inch of his manhood. Five inches; then seven. Finally ten, eleven and twelve. Curt could feel the round end of his prick start bouncing against the inner wall of Christa's cervix, as she took in all she could length-wise. Lowering her hands to the six inches remaining outside, she stroked his erection as she fucked the upper foot. Still the tingling grew.
With a deep moan, Curt could feel the spunk churning in his balls. "Watch ... watch out ... Christa. <pant> Here ... here <grunt!> I ... cum...!" The pressure exploded inside him and spread along his shaft with lighting unlike any in the previous experiences. Curt watched as his rod began to grow again. And grow...
Inch by inch, his erection grew longer and thicker. He could scarcely believe it. He watched as his once-small penis broke all boundaries. Past eighteen inches ... past twenty... Curt's balls bucked and pumped their contents into Christa's vagina with a force like a garden hose. Spurts of semen squirted from around his embedded cock as it grew wider and thicker; stretching Christa's cunt ever further. Christa wasn't getting off... She stayed glued to his boner, riding it like a horse and crying out in ecstasy as she was expanded beyond belief.
Twenty-two inches passed and twenty-four neared as Christa was forced halfway to her feet by the rapid progression. Curt's cock, now at least four inches across continued to expand. Curt gasped as his gaze settled farther down. His balls were enormous.
The two large sacks bounced and jiggled like bowling-ball sized water balloons! More and more cum leaked from Christa's orifice as she rode and bucked with Curt's hips. Finally, with a look of pain -or perhaps resignation at attempting the impossible- Christa pushed with all her strength against the bed and pulled her cunt off Curt's expanding member. Cum spurted up her body, across her tits and drenching her hair. Still growing, Curt watched with awe as his balls and rod expanded well into the stallion range of size. Another minute passed and slowly, ever so slowly, Curt felt the pressure ease and the tingle return to its normal, background level.
Weary and panting, Curt closed his eyes and lay back on the bed. He could feel his still-stiff pole waving in the gentle breeze of the air-conditioning. Absently, he felt Christa touch his rod softly. He opened his eyes to watch her gently measure along his length and then his balls. She was covered in sweat, cum and excitement. She looked more turned-on than Curt thought a person could look.
She glanced up triumphantly. "My God Curt! You've broken all the records! Twenty-six inches long ... twenty-six, Curt! Your balls are as big as basketballs and your width is," she measured quickly across his still engorged knob, "six inches across!" She glanced down at the base of his rod and smiled. "An' that's only the tip ... you're at least a good two inches thicker at the base!" Wiping a handful of cum off her face, Christa proceeded to slowly slurp it up. "You always make the best dinners," she said coyly.
Curt sat up as his cock deflated and started to hand heavily across his lap. It took a full two minutes for the erection to go down. Gingerly, so as not to knock his giant's balls against his knees, his swung his feet over the bedside. His dick must've weighed close to fifteen pounds! Swinging it over the edge, he could feel it pull heavily against his midsection and his balls knock together enticingly. Curt winced as the tingle got momentarily stronger. He could almost feel himself start to rise to attention again. Gritting his teeth and forcing himself to remain un-aroused, Curt patted Christa's shoulder. "Look ... it's getting tough to resist more sex. Can you get the formula in here now?"
Broken from her size-induced revelry in Curt's cum, Christa looked momentarily distracted and crestfallen. Then, with a slow, weary nod of her head, she walked out of the room to return after a minute with Curt's mason-jar-sized beaker. "Well," he said as he dipped a corner of the bed sheet into the mixture, "say 'goodbye' to 'junior'..." With that, he began dabbing the blue liquid over his penis and testicles. It didn't seem to be drying right away, like the first formula, but it did stain his skin similarly. After several minutes of generous application, Curt lay back on the bed and waited.
An hour passed with no effect. The tingle was still there. A cold chill descended on his heart as he began to suspect that his work had failed like last time...
'Like last time...' The thought raced through his head. Christa was lying next to him gently rubbing his back. "Christa..." She looked up into his eyes slowly.
Curt cleared his throat. "Christa; last time I created this formula, it needed stimulation to work ... this time may be the same." Christa nodded, a small smile growing on her face as she realized where this was heading. "I also used a concentrated version. I want to know if you'd like to give me a little ... hand here."
Christa's smile broadened as she nodded assent. She moved to a position straddling Curt's chest and planted both her arms above his shoulders. "Sure ... but this time," she made a rapid motion behind his field of vision, "we do it my way." In a second, a loose strap had been looped around each of Curt's wrists, pinning his arms in place above his head, attached to the headboard. Quickly (and accidentally stepping on one of Curt's balls in the process), she likewise snared his feet and tied them in place.
"Christa? What're you..."
"Hold on Curt!" she interrupted. "Let me try this... Do you agree to let me pump you off until you shrink down to a more manageable size?"
Curt's brow furrowed as he tried to figure out what Christa was getting at. After all, it was obvious that was what he had just asked her. Slowly, he answered, "yes..." She smiled triumphantly.
"Just remember you said that..." And she started to lick and pump him back to a full erection. Curt moaned in pleasure, and watched her as she went. It took two hands, but after a few minutes, she stopped and left the room. A minute later, she returned with a massive, six-foot tall foam-rubber cylinder attached to a pulley and some rope. Still smiling, she looped the pulley up and over the ceiling beam that crossed the room twelve feet overhead. Then, she tied the ropes -around the bed frame beneath him- to Curt's hips. Finally, she pulled the suspended cylinder down and slid it over Curt's erection. Fastening hit around his hips as well. The whole system was tight.
With a smile and gentle pull on the tube, she said "Let the games begin..."
The tube descended along Curt's shaft, erotically caressing its entire length like a giant cunt. Hell, Curt thought, I've even got room to spare! As he automatically pumped his hips against the sensuous pressure, the tube moved in response, pumping him even more. Between his legs, Christa fondled and licked his balls. The tingle began to increase, as he neared orgasm. Forcing his head to watch, should he lock in ecstasy again, Curt glanced at his glans to see the reduction take place.
It didn't. Instead, he began to grow again. Inwardly, he screamed denial as the erotic sensations clouded his mind and sent it spiraling to new heights of ecstasy. Now, his erection truly resembled a horse-sized schlong. Even bigger. As he pumped and came, he watched the base thicken across his midsection, soon reaching a diameter of at least ten inches. He could feel by the rubbing against the inside of the tube that his cock was at least a foot longer. Christa laughed in delight. Curt's balls had expanded to beach-ball size. There was no way he could walk now ... not at least without a wheelbarrow to carry his dick around in. Far above at the top of the tube, he could see a garbage bag billow out from the top, collecting the cum that had shot up that far.
The harness kept pumping.
"Christa ... take it off; it's not working!"
"Oh it's working all-right," she responded, indicating the pulley and rope.
"That's not what I mean!" Curt gasped as his own automatic bucking drove the pump harder along his enlarged member. "The formula ... it didn't work!"
Christa smiled. "Sure; it probably does... But I switched it the other night..."
Curt's eyes widened, as much in ecstasy as shock. "What?!!! You replaced it? <gasp> With what?"
Christa shrugged. "Oil, water and food dye... I've got the real formula in the next room."
Curt clenched his eyes shut as another shudder ran though him. As confused, betrayed and angered as he was with Christa, the sensations of erotic pleasure, began to overwhelm his mind. Dully, he began to enjoy the helpless growth... Christa walked up to where he lay, gyrating on the bed and gently lowered her breasts over his face. Tentatively, Curt's tongue wandered over her lush surface, searching out the sweat and salt on her skin. Smiling, she gradually pulled backwards and grabbed her sweater.
Curt looked at her confused. "Christa...?"
With a shrug, she pulled her clothing on and walked to the double-doors. "Just gotta few errands to run, Curt... I'll be back." She paused and looked back through the door as she left. "After you've had a little time to grow on me..." With that, she shut the door and left.
Curt felt the tingle grow as he started to cum again.
And again... And again... And again... And again...
Christa opened the door to her father's hunting lodge with a light feeling in her heart. She'd taken her time shopping for the groceries they'd need this weekend, but then she'd also taken great delight in imagining how big Curt would get in her absence. From the kitchen, she could hear him still grunting and moaning in the master bedroom. Smiling, she put the groceries away and pulled off her clothes. Sultrily, she walked towards the door.
And stepped in cum.
Surprised, she looked down at the eight-foot diameter puddle that oozed from under the door. Holy shit, she thought, how far had he gone? She'd only been gone a couple hours... Rapidly she flung open the doors and then stood, staring in erotic fascination. Large droplets of cum covered the ceiling, support beams, walls, bed and windows. The puddle in the room was about six inches deep and still warm. Curt had really grown.
The foam rubber tube was stretched thicker and longer by an amount even Christa hadn't expected. The pulley's still worked, but very slightly ... Curt's hips couldn't lift up against his five-foot diameter testicles enough to provide much pull to the pulleys. His cock, massive enough when she'd left, strained at it's foam rubber prison ... three full feet across and sixteen feet long! Massive, blue veins crisscrossed his massive erection, still pulsing with his last ejaculation. Little Curt was barely visible beyond the monster that had become his genitalia. Like a tiny bug on a much larger animal, Curt looked sweaty, tired and ... aroused.
He smiled gently at her as she stepped tenuously into his field of vision. "I knew you'd get back." He glanced his eyes over the length of his penis. "Long line at Rainbow?"
Christa smiled and bent forward to lick the cum from his chest, face and hair. The large plastic bag she'd put over the top of the tube had long since ruptured spraying its contents over the room. His semen was still warm and delicious. She wrapped her arms around his body and undid the straps. Slowly, she removed the equipment and peeled the last remains of the foam-rubber tube from his pulsing member. God, was it huge!
With trepidation, she pulled it down and gave it a tiny lick on the underside of it's head. Slowly, she rubbed up and down the length of his shaft, reveling in the warm feel of the smooth flesh and warm cum glistening on its broad surface. She turned to Curt, "well, I got my wish... Wait here..." With that, she left the room.
Curt raised an eyebrow. "Where would I go?"
A second later she returned. Curt could hear her enter, but couldn't see past his own softening erection. After cumming six times in the last two hours, he was still horny ... it was strange but oddly pleasurable. Vaguely, he wondered if he'd ever be un-horny again.
Christa walked into his view holding his jar. With a smile she shrugged, "I guess you've earned this..." Slowly, she moved to start dabbing it on his erection.
Surprised, Christa looked up.
Curt smiled half-crooked. "I thought we had several days up here ... no reason to go so fast..." Christa looked at Curt, clearly surprised. He laughed at her expression. "Well, what did you expect? I thought you wanted to see how big I could get? Let's see what this baby can do..."
Christa smiled slowly and put the jar down on the floor. Making sure that the bed had rollers she opened the double doors to the main hall. They'd need plenty of room for what she had in mind...
Curt dropped the steaming spaghetti noodles into the strainer and ran water over them to wash off the excess starch. With flair, he flopped the whole, steaming mass into a serving dish and brought it over to the table in the middle of his small dorm room. The neighbors might complain about the smell of cooking Italian food, but he didn't really care.
His over-sized Zubas still took some getting used to, as did the huge three-footer tucked away beneath them. With balls the size of volleyballs it was difficult to hide what he'd become, but he'd have to learn to live with it. Christa watched him walk with amusement and a seductive gleam in her eye. Now that he was guaranteeably bigger than anything on two legs, she was always in the mood.
It was three weeks later.
Smiling he took their antipasto salads from his soda-fridge and served their dinner. It had taken the whole jar, and twelve ejaculations to undo what had been done to him, and even then he was stuck at this impossible size. Still, it could've been worse...
This was the first time they'd been able to get alone together in weeks; both of their studies for fall finals had been hell. Now they had the whole three weeks of Christmas break to spend together indulging their every, carnal desire.
"You ready for this break?" asked Christa through a mouthful of salad.
Curt nodded and started spooning up the noodles and sauce on her plate. "Yeah, bio-chem was a real bear ... I'll be glad to take a break for a few weeks..."
Christa paused and raised an eyebrow at him. "No, you don't understand ... are you really ready?"
Curt put down the spoons he'd been using and crossed his arms. "We discussed this, no more size games with my prick ... I'm lucky it reduced to the size it did! Understand?"
"O.K. ... o.k. ... Can't blame a girl for trying, can ya?"
Curt chuckled, knowing her, she 'tried' every six minutes. "No ... I suppose I can't..."
Christa stabbed another bit of the antipasto and smiled. "This is really good, Curt. You learn this recipe at home?"
"Oh no ... Betty Crocker is good enough teacher for me." He paused to sip from his Coke. "Still, I did make the vinaigrette myself..."
"Really?" She munched another mouthful, enjoying the play of flavors and spices. "It's really good ... 's gotta 'tang' to it that I don't recognize."
Curt smiled slowly. "Oh, that's the special ingredient..." Again he sipped from his Coke, satisfied. Then, sitting back, he began watching Christa's chest...
