Sci-fi Sex Story: "I need to test some equipment that I have designed." Emily said as she lubricated his large semi-erect organ with petroleum jelly, admiring its veined shaft and bulbous head. "It's a device that draws semen from a male using a robotic milking action. We have chosen you because the device is a bit too large for the average consumer, but I think it will fit your 'endowment' quite nicely

Robotic Dick Milking Machine Illustration


The year is 2068. Biological weapons of modern times have been designed with the specific purpose of causing mass sterilization among human males. Although none of these weapons has been detonated, the threat is very, very real, and a plan for contingency is imperative.

Not wanting to take any chances, the government has contracted with a roboticist specializing in reproductive efficiency named Emily Simms to create methods of maximizing ejaculatory productivity in human males.

In the event of a disaster, this technology could be used on males unaffected by the sterilization to continue creating enough healthy sperm to allow society to perpetuate itself. Dr. Simms was given half a year and a substantial government grant to complete here task. Our story begins at the end of those first six months...

Dr. Emily Simms had just completed the final assembly of the prototype for her robotic penis milking machine and was taking a moment to reflect on the six months of planning and hard work that it had taken to get to this point. Penis milking had been an obsession of hers since her late teenage years. She loved the idea of a helpless victim forced to orgasm repeatedly as many times as she wished. She often found that she was able to bring herself climax just from the sight of such a session.

"It's a little big, don't you think?" Sarah, her lab assistant asked with a touch of concern in her voice. Sarah had seen many penises in her 24 years, some of them quite large, but never one that could fill the double-walled cylinder that was on the workbench in front of her.

The robotic milker was a menacing-looking contraption that was a full 15 inches in length with a diameter of five inches at its base. It was basically a large glass cylinder with a doughnut-shaped motor at the base and a smaller cylinder at the top for semen collection. Inside the large cylinder there was a bellows made of connected black inflatable rubber rings that formed what Dr. Simms referred to as the "suction sleeve". The sleeve was slipped over the shaft of the male organ and as the rings that formed the sleeve were inflated and deflated they would move back and forth along the length of the penis. The inner diameter of the suction sleeve was tightened on the upstroke and loosened for the reciprocating downstroke, creating a "milking" effect. A black rubber suction cup was fitted to the head of the penis and connected to the semen collection chamber. During the extraction, a vacuum pump was used to make sure that all of the ejaculate was drawn out of the suction cup and into the collection chamber.

"I suppose you're right," replied Emily, "I was limited by the size of the parts that I could find, most of them were available from equine breeding supply houses.

"So what we need to find is someone and willing to have his dick sucked by a machine that looks powerful enough to pull a tree out of the ground and who just happens to be hung like a horse." Sarah replied.

Distracted and fiddling with the electrical connections of the device Emily agreed with her assistant, "He'll need to be at least 10 inches or the head won't reach the collection cup. The machine will still work, of course, but when he ejaculates, it will squirt everywhere and run down the inside of the walls of the glass cylinder. If enough semen spills into the motor it could potentially damage the electronics."

"Ten inches!" Sarah exclaimed. "Who do we know that has a ten-inch cock?"

"I do." Came a deep voice from the shadows of Emily's Laboratory. As he stepped forward with a mop in one hand and a bucket in the other, Emily and Sarah could see that it was Connor, the janitor.

"Damn, Connor, you scared the shit of me just then!" Sarah exclaimed. "I though you didn't come in on Thursdays?"

"It's Friday, ma'am." Connor replied with a smile.

"So," Emily interrupted "are you telling the truth?"

"About the day of the week?" Connor asked, "Why would I lie about..."

"No, no, not about that," Emily replied, "About the size of your...penis. Is it really 10 inches?"

"Almost 11 when it's really hard and about eight soft." Connor said matter-of-factly. "Damn thing is a curse if you ask me. Every woman I've tried to fuck says it's too painful for them to take all the way inside. I usually end-up settling for a hand-job, which is just about the only way the women I've been with can gratify me without hurting themselves."

"I see." Emily replied. "Do you mind if we, I mean, would you...show it to us?"

"If you really want me to," Connor said glancing around the lab to make sure no one else was there to see. He placed the bucket on the floor and rested the mop against a large bank of computer equipment. He unzipped the fly of his coveralls and fished out the biggest cock that either Sarah or Emily had either laid eyes on. It was a big flesh-colored hose bulging veins throughout its length and a shiny pink head at the end. He let go of it and the two lab technicians watched his dick swing between his legs like the trunk of and elephant. "There you go." Connor announced. "Like I said, it gets bigger when it's hard."

"I'm sure it does." Sarah snickered. She was fascinated by the huge phallus that was hanging between Connor's legs. She was also intrigued by the fact that in a situation that would have caused most men to be as stiff as a flagpole, Connor's penis was, as far as she could tell, completely flaccid. "Can you make it get erect for us?" She asked. "I want to see if you're really telling us the truth."

"Well, that's not as easy as you might think." replied Connor. "Because I'm so big, it takes a significant amount stimulation for me to get a full erection. It took my girlfriend and her little sister blowing me at the same time nearly 15 minutes to get it fully hard."

Emily turned to Sarah "I'm going to go upstairs to get a tape measure." she announced."I want him fully hard by the time I get back, understand?" She said in a commanding tone.

"But how am I supposed to..." Sarah pleaded

"Think of something!" Emily snapped. "Why don't you show him those big tits of yours?" Although Emily was had very well-endowed breast herself, they were no match for her lab partners huge knockers. Sarah had always been envious of Emily's endowments and although she did not know for sure, she estimated that they must have been a DDD cup at least.

"Yes ma'am." Sarah replied.

Emily walked up a flight of stars and out of the door that led to the supply room.

"Well, you showed me yours, I guess the least I can do is to show you mine." Sarah removed her white lab coat and through the thin material of her tight knit blouse Connor could see that her breasts were gigantic. Sarah smiled as she noticed Connor's big hose pulsed once, and then again, causing the head to bulge and the shaft to thicken slightly. "You like these?" She asked as she squeezed the big mounds in her shirt together, creating a deep valley of cleavage in the v-neck of her blouse.

"Uh...yeah." Connor replied. "I guess you could say that I'm a breast man."

"Really?" Sarah asked with a big grin. "Then I guess you wouldn't mind if I did this..." She crossed her arms and grabbed the bottom of her blouse and with one deliberate and smooth motion, pulled it over her head and tossed it on the floor. She now wore only a black lace bra that barely concealed her massive breasts, a short bright red leather mini-skirt and knee-length black leather boots.

Connor couldn't help the fact that his cock was beginning to stiffen and instead of pointing at the lab floor, it was now about one-third of its full hardness and climbing steadily.

Sarah walked over to him and asked for permission to touch the magnificent specimen that was beginning to swell obscenely from between his legs. "I've never seen one so big before...do you mind if I...I mean, can I touch it?"

"Sure," Connor replied, "on one condition."

"What's that" Sarah asked.

"Take your bra off first". He commanded.

"I really don't think I should..." Sarah teased.

"Have it your way..." Connor said and began to stuff his big semi-erect dick back into his coveralls.

"Wait, OK, OK. Here, I'll do it." Sarah asked as she reached behind her and undid the clasps of her bra. As she bent her arms to reach the middle of her back her breasts were thrust forward, causing Connor's big penis to pulse and thicken a bit more.

The cups of the garment fell away and her massive tits bounced free. They were the most perfectly shaped breasts that Connor had ever seen, although very large, they had a very natural shape and rested proudly on her chest. Seeing her naked boobs caused his organ to swell again. By now he was more than halfway to full hardness, and Sarah was just getting started. "Most guys are a little overwhelmed by them," She announced "but you seem to be handling it quite well..." she smiled her stare transfixed on his cock.

"Now can I touch it?" She asked shyly.

"Be my guest." Connor replied.

Sarah slid her thin fingers around the bulbous head that was now quite large. "It's just that I've never seen one...so big..." The half-naked woman slid her fingers of her left hand all the way down the length of the thickening shaft until she reached the base. She tightened the grip with her left hand and began massaging the head with her right. A single droplet of clear fluid had formed at the tip which she squeezed and smeared over the head with her fingertips.

Now with a more deliberate "milking" motion she began to slowly pump the entire shaft, first with her left hand, and then using both hands. Her manipulations were having the desired effect and Connor's big dick was now hardened to nearly its full size, Sarah was beaming with amazement and satisfaction on the effect that she was having on him.

"I see you've gotten to know each other a little better." Emily said as she was walking down the stairs from the supply room. She had a tape measure in one hand and a small vile of clear liquid in the other. "Let's see if our friend here was exaggerating about his endowment, shall we?" She handed Sarah the tape measure and walked over to the workbench with the vile of clear liquid. While Sarah and Connor were fumbling with the tape measure, Emily held her breath and poured the contents of the vile into a clean cloth.

"Well, looks like he was telling the truth Emma," Sarah announced "ten-and a half, and I don't think he's completely..." She stopped when she saw her partner struggling with Connor, his big cock flapping from side to side. Emily had the cloth covering his mouth and had no intention of letting go. "What the hell?..." Sarah queried.

Connor's struggling weakened and within a few moments he collapsed on the stone floor.

"Don't just stand there!" Emily said to Sarah, half-shouting. "Help me get him undressed and up on the table."

Man Tied Down with The Robotic Dick Milking Machine attached to him and Being Operated by two Naked Girls

Half-naked and still a bit unsure as to what was going on, Sarah did her best to help Emily lift Connor onto the large wooden table. Both women were in good shape and using their combined strength they were able to hoist him into place without too much exertion. Emily undid the laces of his work boots and slipped them off.

"You want to tell me what's going on?" Sarah asked Emily as they began to strip him of his coveralls. "Why did you have to knock him out? He might have been very willing to cooperate if we would have just..."

"Look, I'm under a lot of pressure here!" Barked Emily as she struggled with his undershirt. "I have a project that is about 20 thousand dollars over budget and a government contract that is about to expire. If I don't have some concrete results to prove that my invention works as well as I have claimed it will, we're finished, do you understand? They'll shut this lab down, Sarah. We'll have done all this for nothing. Is that what you want?"

"Well no, of course not." Sarah replied as she removed his underwear. Once he was completely naked she decided he had quite a good-looking body.

"Then help me with these restraints," said Emily, "the effects of the chloroform will only last another four or five minutes - we need to move quickly."

The table was a large wooden slab for a top that hinged on a pivot that allowed it to tilt a full 90 degrees from fully upright to fully reclined. The slab had a series of five large steel rings bolted to its head and five rings to its foot. There was an additional pair of rings on in the middle of the table on either side of Connors hips. These rings would later be used to strap the dick milking machine in place.

Using thick leather straps and the kind of metal clips that Sarah had seen mountain-climbers use, the two women secured Connor to the table in a full spread-eagle position. His massive organ, now flaccid again, was draped over his left thigh; the two women were still amazed at its enormous proportion.

Connors hands and ankles were bound in leather cuffs that were padded with soft wool. The idea of the restraints was to hold him firmly in place, but not to cause him any pain.

Emily slipped off her lab coat and proceeded to remove her blouse, slacks and bra. She had inserted her thumbs into the waistband of her panties and was about to slide them off when Sarah noticed that her lab partner stripping with the same casual attitude that one might butter a slice of toast. "What are you doing?" Sarah asked.

"Getting undressed, what does it look like...?" Emily replied matter-of-factly.

"Well I can see that." Sarah replied. She had never seen Emily nude before, but had often admired her lab partners slim waist and full breasts through her clothing. Seeing her tanned and voluptuous form fully naked caused a mixture of feelings inside her. On the one hand she felt slightly embarrassed, but at the same time she felt mildly aroused. "I took my top off to help give Connor and erection, is that what you're doing, too?"
