Alex, still groggy from his marathon bout with spinning Ginny, was a bit surprised to wake again to Dr. Smith, in surgical rubber gloves, conscientiously measuring his huge organ with her tape measure and chart. Shaking her head, she noted the stats on her clipboard, talking into a throat mic.
"Remarkable. Even larger than with Honey. I assumed that perhaps the tight vagina might trigger detumescence. However, this petite partner proved to have more than average vaginal capacity. But, at least anecdotally we have shown that there is no correspondence between a woman's stature and her vagina. Subject also seems to have superior stamina. Is this due to the test product or to his physiology? And as long as the subject remains hydrated then repeated ejaculation in a relatively short period of time is possible. Again, is this the individual or the substance, or some synthesis? Oh, I'm sorry, I thought you were snoozing. I have been talking to myself."
Alex smiled.
"No problem. I kind of like hearing you think. So. What's next? Should I quit? Do you have the stats you need? And by the way, you owe me a coffee date, maybe two ...technically."
Dr. Smith smiled politely.
"We'll see. For now, let's stick to the study; although, as you well know, we have a new factor. Previously we were not collecting your ejaculate. Now it seems we should. I think a more complete study of the properties and effects of it can happen at a later date if you are agreeable. However, since we have had this unusual result with Ginny, and before we test you with another partner, perhaps we should collect a sample of this particular ejaculate. There could be something in the combination of the drink you had and your own particular chemistry, or it might be something in the fluids of the young woman. You were drinking the raspberry, correct?"
"That's right."
"Have a little more. This is a measured quantity."
"Now you want me to beat off, kind of like a sperm donation."
"Not. Yet. We should clean you thoroughly so that there is no residue from the previous young woman."
"So I should go shower, right?"
"Perhaps it will be best if I supervise and aid in that. I would like to make sure you are immaculate. You understand?"
"So, my penis is still huge and now I'm getting embarrassed. Can I reduce this damn thing? I don't want to knock over furniture or anything."
"Very droll. But I would like you to maintain it as it is until it is cleaned. The previous time the reduction caused some expression of fluid and I'd like to capture all of the current sample. So, please follow me."
Alex did, and Dr. Smith led him into the restroom. He trapped his mammoth schlong against his belly with the tie of his robe. She had him stand in the shower while she hit him with the special spray head to toe from every angle. It was provocative and strange having this woman spraying his great dick and then scrubbing it with a washcloth and also scrubbing every inch of the rest of him, starting with his face.
"I don't understand a couple of things," Alex asked, catching his breath as she swathed his nipples. "Why my face and such? They are nowhere near my ...Oh that's nice, but why are you doing this? Couldn't one of the orderlies ...? Do that again, please. And, how do I put this? Please be as rough and clinical as you can, because you may get "results" sooner than you wish."
Dr. Smith continued cleaning him, down each leg, even between his toes, which was remarkably sensual, despite her 'clinical' touch and a bit of clear liquid oozed from the tip of his distended penis. Dr. Smith saw this, stopped for a moment, thinking. Then, in a move that stunned Alex, she copied Ginny and swiped up the drop with her finger, licked it off her finger, checked her watch, noted the action on her clipboard, and then went back to cleaning his ass, then his balls and penis.
"Excuse me? What was that?"
"Oh, sorry. I saw that drop of ejaculate, reasoned that it probably has much the same chemistry of that which stimulated your partner Ginny. I wanted to test it on another subject quickly and decided that I might as well do it myself, since the chemistry seems to change with time. 'Freshness' seems to be critical."
"Ginny would be wetting her knickers about now. How do you feel?"
Dr. Smith stopped and seemed to be listening to her own body.
"The right question. Hmm. I would not say 'no effect at all', but clinically no more than might be caused by the effects of the testing environment."
"By that you mean that this "work" sometimes turns you on?"
Dr. Smith seemed to listen to her body again.
"Yes. Another good question. But since I have never officially monitored myself during this or previous experiments, I can't be absolutely sure."
"You've never had to change your underwear during or after these sessions?"
"Well, Mr. Dupree, you are the test subject, so let's stay focused. But you make a good point. It could be useful for me and members of my staff to wear monitors. Our physical and emotional state could skew our results. Now, if you will please follow me into the adjoining suite."
She opened the door on the far side of the restroom and they found themselves in a room that looked much like a gym, with aspects of a laboratory and a kinky sex play room. There were three beds that looked more like operating tables, though they clearly could adjust to have one or another part raised or lowered. There were ticking machines that could be monitoring his own motions. There was a hammock chair and various bars and racks attached to the wall with ropes, pulleys and cuffs.
"This is our single individual testing room. This is where most of our previous work has taken place. So, if you will please seat yourself on that test bed I will reduce your erection."
"I can do it myself."
"I know you can, but I want to make sure we carefully gather any samples that might be available during that process. After that we will use the 'autostim' device, but frankly, it wasn't designed for a penis of this girth. So, let's begin."
She produced a beaker with a little baffle on the top to direct the cum into it if necessary. Then she began squeezing the base of Alex's swollen rod.
"It is not reducing as quickly as before. Perhaps this is because of a little 'tissue fatigue' or because it is engorged because of previous stimulation."
"Or current stimulation. You'd better have your cup ready."
"Yes, that too. Please restrain if you can. It will be more convenient to collect it all in one sample."
Alex took some deep breaths and clenched his ass. Still, a bit of cloudy liquid leaked out. Dr. Smith quickly scooped it up and went on squeezing. It took several minutes to get him to a reasonable size. Dr. Smith kept squeezing the base but there was no more reduction. Perhaps the opposite.
She eyed his member critically.
"I suspect that there may be a temporary, or even a permanent change." She measured and entered the stats on her chart. "It has happened in previous subjects. Now if you will position yourself right here."
She pointed at two footpads in front of a device that combined electronic and mechanical features and had various deep rubber cups attached to it. There was something familiar about it from Alex's childhood. Then it hit him.
"Of course. A milking machine."
"Quite similar, yes. But with refinements. Now I am going to ask you to stand here. I know many men prefer to masturbate sitting or lying down; but we have discovered that this method is best for quick results. It allows, even encourages the individual to rock much in the way he would do during intercourse."
Alex dutifully took his position. Dr. Smith chose one of the cups; tried it on his penis; rejected it and found another that was a better fit. It was a purple material, not quite rubber, not plastic, with the feeling of skin, but not exactly human skin.
"We are fortunate that you are already erect. Usually we have to calculate for the expansions."
Dr. Smith fitted a wide belt of the same material around his waist and drew another flap with a smaller cup under his testicles.
"Is this thing going to grab me by the nuts?"
"Well, not exactly grab you, but it has a specially designed flexing material, similar to that in the penile cup, but this is uniquely designed to gently massage the scrotum."
"Couldn't you just have a person do this? I mean, I'm not having sex in the other room with a machine."
"Yes. No, well you know that that experiment has another purpose, or purposes. This is best just for getting the semen or sperm. We have licenses being prepared for sperm banks. But we believe that by now you are "shooting blanks" as they say. We are more interested in the seminal fluid. Oh, so now I am going to insert a small device in your anus. This will provide the last bit of stimulation and ensure that you 'empty the tank.' This experience may be a bit stronger than previous ejaculations since we want to retrieve from both testicles. You know that you usually only 'shoot' from one at a time."
"Oh my goodness."
Alex twitched as Dr. Smith had swathed his asshole with a bit of warm gel and then slid a thick finger-sized semi-soft device fairly far into his bum.
"It needs to communicate with your prostate and stimulate your seminal vesicles."
She attached the rear flap to the waist belt with a thick thong that slid between his buttocks. He felt like a sumo wrestler with a garish purple 'diaper'.
"And we're ready. You see there are two comfortable grips at chest height. They adjust to where you need them. For instance, you can thrust fully upright or push them forward so the whole business is more in the 'mounting' position like most four legged animals. Are you ready?"
Alex nodded.
"Good. Now..."
She pushed a couple of buttons and turned a dial and the machine began a low hum that translated to a soft vibration in his nether regions. A touch of warm lubricant oozed around his penis. Not unpleasant.
"Now let the device do virtually all the work of stimulating you, but if you feel you need for visual and auditory stimulation you can put on this headgear. It will provide a 3D experience of the kind of erotic partner you most desire. Can I dial up any particular ...?"
Alex thought for a moment, but given the unusual situation he was not in the mood to watch a porno. Perhaps one of the volunteer partners would be willing ... but that was too complicated. He knew he wouldn't need much, just someone he could imagine he was fucking. They needn't even be undressed. In fact, clothed could even be better.
"Dr. Smith, where will you be during this 'extraction'?"
"Well, usually I return to the control room while the subject ... I'm sorry, of course you need your privacy."
"Actually not. It would be ... helpful if you could remain in the room. I am a bit of a special case, right? I might need some ... adjustments ... or change my mind about the goggles. Yes, please stay."
"Fine. I can take a chair behind you here and if you have any requests ..."
"Thanks. While it would turn me on a little to have you looking at my ass, I'd rather have you over here where I can see you."
"Mr. Dupree, we really need to do this while your specimen is in its original state. But, ... of course. Where do you want me?"
"There's some space between this machine and the wall. Could you just stand right there? Maybe lean on the wall? That'll do it, I think." He smiled.
"Certainly. All right, I can do that. Let's begin. The device normally cycles through phases that will take the average man to climax in a few minutes, often less."
She turned from him as she programmed the device. He liked the few tendrils of dirty blonde hair that drifted onto her neck. Alex had not really had a chance to look at her closely before then. She was a slim person of, he guessed, about thirty-five from the fine lines at the corners of her eyes and the little smile creases at the corners of her mouth. Her lower lip was slightly puffy and her upper lip had a fine sculpted edge. Her eyes were a dark amber behind simple glasses, her hair a similar shade, straight and pulled into a decorative clip at the base of her neck. Small diamonds in her earlobes. He couldn't tell much about her figure; above average height, a pert bosom, buttocks that shifted when she walked. Yes, that was her secret weapon! She had an athletic ass that she kept well disguised in a simple straight skirt that stopped about three inches above the knee. Really nice feet in simple pumps.
"I'm curious. How is it controlled?"
"Well, we start the program with your basic specs and then it can be pretty automatic. If need be I manipulate it from the control booth, ... and I think we need to begin. You can also control some of the action with the handlebars. Right for intensity, left for speed."
"Can you put the clipboard down?"
"Why?"
