The Expansion Experiment

"Angie, you still have not experienced orgasms. I need you to focus on visualization and relaxation so you can achieve an orgasm. On the positive side, you are now a 49G and are producing a full pint of milk each day - one of the largest quantities of milk production in the group."

"Tracy, you are now a 39E but you are only producing a half pint of milk. Please do not be discouraged - any day now your milk production should increase to qualify you for station six."

"Hitomi, congratulations," Johnson announced, " Your attendance has been impeccable since your tardiness and you now have a 37D. Moreover, you produced a full pint of milk today. It is your good fortune to join Jenn in station six."

Johnson led Hitomi to station six and Jenn gave her a congratulatory hug. "Does that bed mean what I think it means?" Hitomi asked.

Johnson gave her the same explanation for station six he had given Jenn and then paused staring at Hitomi for a response.

"Look, at this point, I'll do whatever you tell me to do," she said. "I thought this whole idea was crazy, but now my breasts have gone from a B to a D cup - so you tell me what to do and I'm on board."

Johnson smiled at her and began to remove his clothing. "I take it you are somewhat experienced sexually?" Johnson asked. Hitomi nodded. "And per the requirements of the job, you are not using any birth control methods?" he asked.

Hitomi nodded. "I was on the pill but I stopped taking it. Now I make my boyfriend pull out - he actually loves it." She gently pushed her breasts together. "Now all he wants to do is fuck my tits and cream on them."

"Well that is good, but for purposes of this protocol it would be better if you ingested the sperm orally, vaginally or anally as the proteins in the sperm facilitate breast growth." Hitomi nodded seriously, trying not to laugh at the doctor's elevated language.

"Jenn benefited from Gus's large quantity of sperm yesterday, so it's your turn," Johnson noted. "Perhaps you could kneel and perform oral sex to completion for Gus."

Hitomi approached Gus, who was just finishing removing his socks, and, placing her hands on his hips, began to suck his cock. Johnson watched the skilled cocksucker engulf Gus's average-size cock in her mouth, flitting her tongue around his scrotum as she took him fully in his mouth. "Agh!" Gus cried out in orgasm and Hitomi began to suck faster, gripping his ass cheeks as she pulled him into her.

"Suck out every last drop!" Johnson shouted. Hitomi complied, sucking forcefully on Gus's cock, draining every drop of sperm from his cock.

"You are very efficient," Johnson admired. "Perhaps you can take this refractory period as an opportunity to instruct Gus in cunnilingus." Hitomi nodded and led Gus to the bed. She couldn't believe the volume of sperm Gus had produced.

"Jenn, sweet Jenn," Johnson murmured to her. "I know it is not professional to feel affection for a student, but I find you endearing and sweet," he told her. Jenn smiled and took Johnson's cock in her mouth. She had watched Hitomi suck cock and wanted to try to emulate her technique.

"Very good," he told her. "I can see you are learning. And moreover, I can see you are dedicated to learning and to the protocol." Jenn nodded.

"Do you want to do something special?" he asked Jenn. She nodded without pausing to suck his cock. Johnson rolled her over onto her belly and produced a jar of lube. He gently lubed her asshole and began to probe her ass with his fingers. "Yes," he told her, "I am going to anally penetrate you."

Jenn let out a whimper as Johnson's cock pressed against her anus. "Do you not want to do this?" Johnson asked.

"I want you to do this," Jenn told him. "Very good," he told her, pressing past her entryway. Jenn gripped the sheets, flattened against the bed.

"Check it out," Hitomi directed Gus. "Professor is fucking Jenn up the ass."

"Please use clinical terms in the laboratory," Johnson reprimanded her.

"Sorry!" Hitomi called out. "Ah," she nodded to Gus, "You've got a hard-on, I mean an erection again. Permit me to retrieve your sperm orally or vaginally," she told him jokingly. Gus couldn't believe it. Two days ago he was a virgin and he was about to have sex for the fourth time.

"Ohh!" Jenn cried out as Johnson deepened his penetration.

"Your anus is tight," he informed Jenn. "It won't be long before I climax and the walls of your rectum will absorb the proteins in my sperm." He continued to thrust, his legs straddling her large ass. Johnson groaned and thrust even deeper into Jenn, his penis ejaculating forcefully. "Oh god, you are such a good research subject," he told Jenn, collapsing onto her back.

Meanwhile, Hitomi had mounted Gus and was rhythmically rocking her hips. "Damn you are easy," Hitomi laughed as Gus orgasmed forcefully.

The foursome hit the showers laughing. "I made station six," Hitomi sing-songed, "and I've got big tits!" as she rocking her hips back and forth, her D-cup breasts swaying.

***

The women were astonished as they looked at each other in lineup. A cup Jolene was now a full D cup and Jenn was an astonishing J cup, her breasts swaying prodigiously with every movement. When Johnson announced that Hitomi had joined Jenn in achieving station six, Hitomi stepped forward and, holding her clasped hands above her head, danced around in celebration.

"And I would like to especially thank Gus for his work with Hitomi in station six," Johnson announced. Gus smiled and Hitomi rushed up to him and gave him a kiss on the cheek. Johnson was pleased by Hitomi's reaction. She could see the other women burn with envy.

"From now on, I will not announce who has achieved station six," Johnson noted. Hitomi continued to beam and Jenn, shy, showed no emotion.

The protocol continued. The women were now up to a full four hours on the machine but Angie had still not orgasmed and Tracy was not yet producing a full pint of milk. Jolene was now invited to station six. Discouraged, Angie and Tracy left the building alone, each wondering if they were the only ones who had failed to achieve station six.

Jolene was introduced to station six, as Jenn and Hitomi had been. And like them, she had been challenged to accept station six - and likewise she had assured Johnson of her willingness to engage in sex as part of the protocol.

"Gus will attend to Jolene," Johnson noted, "but we are accelerating the protocol." He pulled back a curtain and eight young men entered the room. "These men will be donating their sperm to the protocol. They are young, free of sexual diseases and in good health. They have been fed the same special diet Gus and I have taken and should be able to produce large quantities of sperm and ejaculate multiple times per session. By introducing these men, we will be able to deliver a greater quantity of critical proteins to you."

"Bring 'em on!" Hitomi laughed. Jenn looked nervously at Johnson. She felt safe and comfortable with Johnson and she sort of thought of Gus as Johnson's son - someone she should care for. But all of these men - men she had never met - she was expected to be sexually intimate with them?

"Hitomi is committed," Johnson slowly noted, "what about you Jenn? Are you committed to my protocol?"

Jenn nodded, fighting back tears. "Very good - you are my best subject and I only want the best protocol for you. I will monitor your sperm intake," he assured her. Hitomi stifled a gigle.

Jolene had already begun performing oral sex on Gus. He had developed more stamina but he once again blew his load within minutes. Jolene greedily sucked his cock - she didn't want to deviate from the protocol one bit. Finally, Gus had to free himself from her vacuum seal grip.

Meanwhile, Johnson was instructing the men to form a line. "You will each receive oral sex from Jenn until you ejaculate in her mouth. It is important that you ejaculate entirely in her mouth and you not withdraw your penis until she has sucked all of the sperm from you." The men nodded, some of them smiling.

"Hitomi, why don't you partake of my semen while I observe Jenn," Johnson suggested. Hitomi began to apply her blowjob skills to Johnson while he instructed Jenn in servicing the men. Johnson had selected sexually inexperienced men and as a result, the men required his instruction and also climaxed quickly and with large volumes. Jenn felt she could not contain the ejaculate as the men in succession blew their loads down her throat. By the time the eighth man climaxed, Jenn felt like her entire stomach was filled with sperm.

"Rest up for a few minutes," Johnson instructed the men, "while I attend to Hitomi." He began to quicken the pace of his thrusts and before long, he climaxed, ropes of cum splashing inside Hitomi's mouth. Dutifully, she sucked out every last drop and disgorged his penis from her mouth with a kiss. "Very good, Hitomi," he told her.

"Jenn," Johnson asked, "How would you like to receive your next round of sperm?" Confused she looked at him with wonderment. "Orally, vaginally or anally?" he asked her.

"Um," she responded slowly. "Let's just stick with orally," Johnson noted. "I think it is the most effective method."

He lay Jenn on the bed on her back, her head hanging over the end of the bed. "In this manner, the men can deep throat you with little effort on your part. I'm erect again, so I'll show you and the men how it is done." He approached Jen and, parting her lips, inserted the full eight inches of his erect cock into her mouth, his cock making a bulge in her throat where he was penetrating her esophagus. "Note that my cock is fully entering her throat," Johnson indicated, lightly caressing Jenn's bulging throat where the head of his penis was visible. "In this manner, my ejaculate will directly enter her stomach. Moreover, the tightness of the esophagus will expedite the climax."

He gently thrust his cock in and out of Jenn. "Relax so you can accept my full eight inches," Johnson instructed her. Jenn complied. He began to fuck her more aggressively and Jenn felt like she was hanging on for dear life. Finally, Johnson plunged his cock fully and held firmly as his ejaculate shot straight into her stomach. Slowly, he withdrew his cock. "And so," he noted to the men. "Form a line."

Johnson kissed Jenn on the forehead. "Sweet Jenn, would you like me to stimulate your clitoris to orgasm while you ingest the sperm?" Jenn nodded - she loved the professor so much. She couldn't imagine doing all of this if it weren't for how deeply she loved him.

"None for me?" Hitomi asked. "Tomorrow," the professor responded. "There will be even more men and we will continue to increase the intensity of the treatments." Hitomi smiled but at the same time, she felt worried about where that intensity might lead.

Johnson performed cunnilingus on Jenn while the men began to thrust their cocks fully into her mouth. Most of the men could not reach her esophagus, which was a blessing to Jenn, who struggled to accommodate the professor. When the sixth man approached her, Jenn remembered that he had an oversized cock - even bigger than the professor's. She began to freeze up, but just then she found herself climaxing from the professor's attention. The man plunged his cock in fully and she found herself overcome. It literally felt like the man was fucking her stomach. Meanwhile, she groaned in orgasm, her vibrations bringing the man to climax - load after load shooting into her stomach. The seventh and eighth man were a blur and as she rose, she felt like she could feel sperm sloshing about her stomach. Hitomi put her arm round her. "You are a champ," she told her. Jenn was appreciative of that kindness, but too tired to even smile.

In the shower, Johnson held Jenn in his arms. "Jenn, you did so well. I wasn't sure you could handle all of that, but I reminded myself that you are my very best student." Recovered, Jenn beamed with pride and reminded herself that the professor wouldn't ask her to do anything she wasn't capable of.

***

When the women arrived, they gasped at the size of Jenn's breasts. She was now an M cup and as she stood, she held her breasts in her hands for support. The women complimented each other on their progress, calling particular attention to Jenn. Jolene - once an A cup, was now an F cup and Hitomi was a 39G.

The protocol continued yet Angie still was unable to orgasm and Tracy was not producing sufficient milk. These outcomes puzzled the professor but he also liked the idea of withholding station six as a motivational tool. He thought Angie would balk at station six - withholding it from her would lead her to desire it more than ever.

The same group entered station six as yesterday. Having seen Jenn's progress, Hitomi and Jolene were eager to ingest as much sperm as possible.

The professor pulled back the curtain and revealed an additional 18 men. "Today, the protocol advances again." The men were all new as the professor had the men arranged on a five day cycle to maximize sperm production. Combined with their specialized diet, the five-day absence would cause the men to produce massive loads for the women.

"Hitomi, you have waited for this day," the professor noted. "Today you will receive sperm from eight men. "Jenn, you seemed to struggle yesterday, so we will also hold you constant at eight men." Jenn hung her head at this comment. She thought she'd be relieved not to have to service more men, but her stronger emotion was shame at letting the professor down. "Jolene, we will start you with four men, including Gus and myself."

The sex progressed as before. The professor began first by face fucking Jolene to a powerful orgasm. Hitomi was sucking off the men to orgasm in short order, quickly bringing the men to climax and draining their balls. Jenn was working through the men slowly. By the time Jolene had brought her four men to orgasm and Hitomi had worked fully through her eight, Jenn was still performing oral sex on her fourth man. She looked nervously about and tried to remember what she had seen in Hitomi's technique.

"Jolene, I want to test your commitment to the program," Johnson noted. "I am going to insert sperm into your anus. Have you had anal sex before?" Jolene shook her head slowly from side to side. "Very well, I will use ample lubricant," the professor noted. He slathered her ass crack with lube and then slowly penetrated her ass.

Jolene grimaced and Gus pet her head. "Oh God," Jolene cried out, "I actually like this!" Johnson continued to forcefully fuck her ass, finally climaxing. Gus clambered on top of her and before she had a chance to move, entered her ass and similarly began pounding away. He couldn't believe how tight it felt and within minutes he was ejaculating forcefully. The two remaining men shrugged and followed suit, depositing loads in Jolene's ass. She stood up and walked slightly bow-legged, sperm dripping from her ass.

"Lie down, lie down!" Johnson commanded, positioning her on her stomach. "Allow your rectum to absorb the essential proteins!"

Hitomi had just finished the second round of the eight men. "Can I help Jenn finish up?" she asked the professor. "I can keep going."

"Do you want that, Jenn?" he asked her. Jenn sadly shook her head no. She still had seven men left to fuck. "You can fuck my ass," she told the remaining men. They brightened and the professor spread lubricant on her ass. She lay on her stomach, her breasts holding her up. Each man mounted her and penetrated her anally, forcefully ejaculating. After the eighth man, the professor came up to her and put his arm around her.

"Just lay here a while," he told her. She nodded and lay her head on her side, resting like a beached whale.

"Damn," Hitomi exclaimed. "That girl has determination!"

***

At lineup the next day, the women were once again amazed by their progress. Angie scowled, noticing that the other women seemed to be making more progress than her. Hitomi, once a C-cup was now a full I cup and Jenn was an insane P cup. Jolene, once a measly A-cup, now had fully swollen G-cup breasts that hung down nearly to her belly. Johnson noticed that Jenn seemed very tired. Her P cup breasts hung down to her belly and she seemed to struggle to support their weight. For a moment he felt concern for her but then he quickly was absorbed with the possibility of her breasts becoming even larger.

Tracy was now qualified for station six, having produced a full pint of milk - barely. Meanwhile, Jenn was producing a full gallon of milk and Hitomi a half gallon. Angie still had not orgasmed. Originally, the professor had used that as an excuse to limit the number of women at station six, but now he felt obligated to continue to use that as a criteria for entry.

Tracy was overjoyed at her entry to station six. "You may not be so happy when you find out what station six entails," Johnson warned her as he walked her into the station.

She saw the bed and also saw Jolene, Jenn and Hitomi waiting for her. Johnson explained the role of sexual activity in the protocol. Tracy seemed confused. "Do you understand?" Johnson asked her.

"You mean I'm supposed to fuck you," she asked.

"Well, not specifically me," the professor qualified. "We have multiple volunteers to provide sperm to you."

"I love to fuck," Tracy told him. "I don't want sperm donors, I want to give head and fuck guys."

"Well, I wouldn't phrase it exactly that way, but I think it's safe to say you'll be fine with the requirements of station six." Tracy gave Hitomi a high five.

This time, when the professor pulled back the curtain, there were 48 men. The women gasped. "Hitomi, I'm pleased with your capacity to ingest sperm. If you think you can handle it, I'm doubling you to sixteen men." Hitomi gave a fist pump and smiled. "Jenn, I'm not sure of the right number for you. You are making such amazing progress and I'd like to continue that, but I don't want to overtax you." He paused. "How many men do you think you can accommodate?"

"Twenty-four," she told him, looking him straight in the eye.

"If I give you twenty-four men, you have to accommodate forty-eight climaxes. I can't have you wasting valuable sperm that other women could otherwise ingest."

"Twenty-four," she repeated.

"Okay, Jolene," the professor noted. "That leaves eight men for you and Gus and I will accommodate Tracy."

"Don't treat me like some rookie!" Tracy complained. "I can do at least ten or twelve men two or three times each!"

"Are you questioning the protocol?" Johnson asked.

"No," Tracy quickly backed down. "Sorry."

Hitomi set to work, quickly bringing the men to climax and eagerly sucking down all the sperm she could coax from their balls. Meanwhile, Jenn had organized the men into a system. The men not having sex with her were jerking off while two men at a time penetrated her anally and vaginally. As the men jerking off began to climax, they hurried over to her and gave final orgasmic thrusts into her mouth. This system worked fairly well until two men began to climax simultaneously. They each chose a side and hungrily fucked her mouth. She struggled to accommodate both cocks, but concentrated mightily so as not to lose any sperm. It felt like the men were jabbing her cheeks as their cocks exploded in near unison. Within twenty minutes, Jenn had brought all twenty men to orgasm.

Hitomi, focused on her own efforts, wrapped up her first round and was surprised to see Jenn taking a break as the men recovered. "You did all twenty already?" Hitomi asked, shocked.

"Yes," Jenn proudly noted.

"Damn you are good!" Hitomi exclaimed. Johnson, observing their exchange, smiled with pride at the accomplishment of his favorite student.

Tracy had quickly brought Gus to orgasm and Johnson had climaxed vaginally. "You can go first in round two if you want," Gus noted. Johnson thought to himself that he knew the reason for Gus's courtesy. The young man wanted to engage in anal intercourse and was hoping Johnson would lead the way.
