Denise was working hard to get Stuart to come first, but her technique was not nearly as effective as Lynette's handling of the boy. Despite this, she tried even harder, making Stuart wince in pain as she dug her fingernails into the ultra-sensitive underside of his cock.
"Ten to one he shoots his load first," Jennifer remarked, waiting patiently for Adam's explosion.
"Younger guys don't usually have the control of older men," Michelle noted, her eyes fixated on the handsome young man's cock.
With Lynette's adept handjob and the two girls' teasing remarks, it didn't take long for Adam to climax. Giving him three quick bursts and a long pull, Lynette coaxed out the first in a series of superb cumshots, all splashing neatly into the waiting receptacle. He must have still been high on the drug because Jill, Laura, and Lynette started laughing when the sticky jets continued to fly long after they normally should have ceased. Rope after rope flew out of the tiny gaping hole atop his prick, coating the inside of the beaker on every side with rivulets of white cream. In no less than several seconds the bottle was half full.
"Fuck," Lynette said still pumping him with all her might, "you shoot out a lot of cum baby!"
Adam could not respond. All he could do was watch her strong, expert hand coax yet another long series of orgasms as his balls continued to fill up with sperm. Jill and Laura shook the beaker back and forth, watching the long streams of creamy spunk splash and ricochet off the inside of the receptacle. They seemed to take a childish delight in this, as if they were watching a cow being milked. Finally, after almost two minutes, the girls held the beaker up high for all of us to see. They shook it back and forth and laughed as the pearly cream sloshed to and fro. I watched them as they walked away toward the outer lab giggly profusely, the beaker about three quarters full of Adam's salty, white essence.
Lynette helped the fatigued boy to his cubicle and left him there while she returned to her seat in the audience. Amazingly enough, not one drop of sperm had touched her hands.
Now it was Stuart's turn to cum. He screamed like a wounded animal as Denise furiously fisted him, shoving the tip of his bloated cock head into the neck of the bottle just as he began to shoot his creamy effluences in short, rapid bursts.
"Get it all out baby!" Denise exclaimed as her hands traveled the full length of him, provoking him to release a flood of hot, white semen.
"No matter how many times I see it," Rebecca said, as she watched Stuart's cum fill the beaker, "I always get turned on when guys shoot their cream."
"Oh, I think it's so sexy!" Sheila agreed. "Especially when they do it themselves."
Jennifer grunted her approval.
"You are videotaping this, aren't you Christiana?" Michelle asked.
"Yes. I have two cameras recording the whole event from the adjoining lab."
She looked toward the wall behind where the audience sat and noticed a glass partition behind which two video cameras were plainly visible.
"Oh, good," she said relieved. "I was hoping you would."
"I'll bet you were," I said interpreting her meaning.
Rebecca gave me a suspicious look.
"But this time the tape is going to remain in my possession," I added.
Both Michelle and Rebecca looked at each other with an expression of innocence, but I knew that if given the chance, they would find a way to make a copy to take away for their own sordid uses, just as Rebecca did with the tape from my previous experiment.
"She doesn't think we would do such a thing does she?" Rebecca asked Michelle.
"I hope not," Michelle replied.
"Oh look!" Jennifer suddenly exclaimed.
There was a sudden round of cheers and applause from the audience.
"Stuart missed! Poor girl got it right in the face!" Sheila said.
The young girl holding the beaker had indeed been doused with an errant rope of spunk that ran up from the bottom of her chin and over her face in one continuous long white line. Luckily, it had missed her eye, but it did not stop her from crying out in distress. Maria quickly ran to her aid and took the beaker from her while the girl ran off toward the bathroom. Despite the mishap, Stuart was able to shoot off several more perfect rounds of sperm into the receptacle as Maria dutifully held the beaker aloft and steady.
Once he had finished ejaculating, Maria took the beaker away. It was more than half full. Denise then helped her husband to his cubicle and joined the others.
Jill and Laura had returned to their seats, acting every bit like excited schoolgirls. What they hadn't expected to see was my assistant Cheryl giving Craig a footjob right in front of everyone.
"Dr. Swensen!" Jill hollered. "Look!"
With that everyone, including my colleagues and all the men still on the platform, looked off in the young girl's direction. I heard Sylvia emit a shallow laugh upon seeing Craig's 16 ½" erect prick being caressed by my assistant's beautifully proportioned toes. Marlene looked on hungrily, as if ready to pounce on the enormous penis like a tiger fervently anticipating wrapping its jaws around a fresh piece of meat.
"Can you believe this?" Rebecca said, breaking into a fit of laughter.
Cheryl's lovely legs were crossed and her right foot was positioned so that she could run her big toe up and down the underside of Craig's prick. At first it must have been achieved by running her foot under his gown, so casually as to avoid detection. But now, the immense tool had worked its way out from an opening in the garment and stood stiff and straight, the tip already dripping with clear fluid.
"Excuse me!" I shouted at the two exhibitionists. "Craig has already given us a sperm sample. We don't need another one, thank you!"
Oddly enough, my statement was greeted by the crowd with groans of disapproval.
"Hey, Dr. Swensen," Barney said, taking a moment to stop Janine's busy hands, "why don't you get that boy up here. Looks like he needs to get rid of some more of his stuff."
Everyone cheered at his suggestion.
"I don't think that's necessary Barney," I said.
"You know Chris," Sheila interrupted, "it might not be a bad idea. He's probably still got quite a build-up of sperm. Might do him good to get rid of it."
"I agree," Michelle said. "You can see he needs milking."
She had a point. I could tell that the boy was in some discomfort despite the pleasurable feelings Cheryl was giving him. After his recent ordeal, maybe further milking would help alleviate some of the pressure he was now experiencing from the increase in sperm production.
"If you're going to do it," I said to Cheryl, "do it up there. I don't want sperm all over the floor if I can help it."
Craig grinned at me sheepishly as Cheryl grabbed him by the arm and escorted him to the platform. After stripping off his gown, she stood him next to Philip, who looked at his huge prick with envy. Bonnie shrugged.
"Keep that thing pointed away from me," she warned Craig. "You've already soaked me twice."
"Yes, ma'm," he replied, blushing.
Philip now stood between Barney, who was positioned on his left, and Craig, who stood nonchalantly to his right. He also stood between a total of over 2 ½ feet of prime cock meat. He looked back and forth at the stiff tools jutting out before their owners in prideful display, making his own penis look paltry by comparison. He looked displeased.
"Let's get this thing over with, shall we gentlemen?" he said, addressing his well-endowed counterparts.
Bonnie clutched at his penis and gave him a sharp tug.
"Listen to me, Philip," she said sternly. "I saw you looking at their cocks. You're not going gay on me are you?"
"No," of course not," he replied, somewhat offended. "It's just that...well, I wish my cock was a bit bigger, you know."
Her grip on his penis relaxed. "Is that what you're thinking?"
"Well, you always said how much you liked a man with a big cock."
Bonnie's face brightened. "You're cock is just fine sweetheart. What I really want is a man with a big heart. And you have that."
She softened up to him then. He had, after all, been thinking of her by wishing his penis were bigger. Though Bonnie did often express her desire to fuck men with big cocks, and often did so with her husband watching, it was merely a passing fancy. What my hardboiled, though insecure, sister really needed was the assurance that her husband loved her, and there was no doubt that he did.
"You may resume," I said to the final three subjects and their masturbators.
The masturbation of the three men commenced innocently enough, with the ladies displaying feats of manual prowess that rivaled anything Rebecca or Michelle might have done. Janine's small hands and stubby fingers sometimes grew tired as they fought to maintain their grip on Barney's humongous prick. She changed hands several times in the next several minutes but I could tell she was becoming fatigued. Cheryl, too, soon began to feel the effects of sustained and energetic masturbation, constantly shifting her grip or changing her tempo as she worked hard to coax out an orgasm. Craig watched her intently as her hands performed their masturbatory duty, now avidly attacking his tortured flesh with brisk, firm strokes and then slowing down to a crawl as her hands started to tire.
Bonnie was suffering no such difficulties. Because Philip's cock was much smaller than the other two men, her long, lithe fingers had less distance to travel than either Janine or Cheryl, allowing her to jerk him off at full speed. When she felt his huge balls start to tighten she began to talk dirty to him in an effort to make him cum. Philip however, fought hard to resist this impulse, believing that the inadequacy he felt in regards to his penis would be compounded if he ejaculated before the other two men. Bonnie sensed this holding back and wondered at it, forcing her to try several other techniques to bring him off quickly.
Philip's insistence on withholding his ejaculation somehow communicated itself to his partners, who began to pace themselves, much to their ladies' dismay. Janine and Cheryl struggled ever harder to provoke an orgasm, but the men held back, treating the whole thing as if it were a test of endurance. So, what started off as a pleasurable way to obtain a sperm sample now became a contest to see which man could last the longest.
After pulling on her husband's penis for several more minutes without any appreciable results, and her hands now becoming tired and cramped, Janine let go of his cock with an expression of dismay.
"What's wrong with you Barney?" she complained. "Why ain't you cummin' yet?"
"I'll tell you why," Bonnie answered. "They're treating this whole thing like it's a game."
"Like first one that cums, loses, right?" Cheryl asked.
"That's it," she replied, relaxing her grip on Philip's cock. "Isn't that right Philip?"
"Oh, come on ladies," Barney said breezily. "We're allowed to have a little fun ain't we?"
"Not at my expense," Janine retorted. "My hands are damned tired and I ain't gonna be pullin' on your big thing no more."
She turned her back on her husband and walked back toward the audience rubbing her hands together as if in pain. Barney watched her walk away with a puzzled frown.
"Where're you goin' woman? You still have work to do!"
