Mr Wizard

The neighborhood laboratory.

In the locker room after tennis, one of Lucy’s teammates mentioned intriguing rumors about the older man in the large house on the corner. She hinted at mysterious activities and the strange smiles on other girls as they left there.

Perhaps too curious for her own safety, she decided to investigate and rang his doorbell on a Monday afternoon. "Good day, young lady" he said, opening the door, dressed conservatively in dark slacks, white shirt, and blue tie. "To what do I owe this pleasure?" Lucy stammered a lame excuse about athletic fundraising, and then admitted that she was curious about his cellar. "My laboratory? Of course, you may find it educational." He let her in, courteously took her jacket to the hall closet, and led her downstairs.

In the cellar, a door opened to a windowless room, two concrete exterior walls and two wood-paneled interior walls. He turned on the incandescent ceiling lights to medium, and escorted her in. There were a half-dozen 19-inch rack-panel cabinets around the perimeter of the room, containing oscilloscopes, power supplies, pulse generators, voltmeters, impedance bridges, spectrum analyzers, and waveform generators. Unfortunately, Lucy did not know what any of those were, but the collection was impressive. Some of the units were switched on, lights glowing, and others displayed waveforms on cathode-ray tubes or numerical results on digital displays. A large number of older units had moving-needle meters instead of digital readouts. Also, bookshelves, tool cabinets, and multi-drawer medical cabinets were along the walls. Nothing like Dr Frankenstein's lab: neither arcs nor sparks, and no hunchbacks.

What attracted her attention, however, was the single piece of furniture in the middle of the rooma medical-looking couch that could be tilted or re-arranged into different attitudes, apparently designed for surgery. Gathering her courage, Lucy asked "so, what do you do down here?" She received the answer she feared "Would you like me to demonstrate? Don't worry, I am fully-qualified (though retired) and harmless. This will take less than an hour, and no one should miss you in such a short time." "Gulp, OK!" (damned curiosity, she thought, it will kill me yet).

"I am perfecting multi-channel devices for female stimulation. This involves both mechanical and electrical stimulation, designed for pleasure not pain," he explained. "I have been fitting them to several volunteer beta testers. So far, all of them have enjoyed the experience, I assure you. I could include you, but you must show me your ID first." She showed him her driver's license, having turned 18 a few months ago, and he accepted her into the test group. "Please sign this release, and then undress (you can go behind that screen) and change into this disposable medical robe. When you come back, please lie down, face up, on the couch." (He was quite confident about that release document; it had been drafted carefully for him by the kinkiest lawyer in Cleveland.)

Lucy complied, carefully hanging her blouse and skirt on the coat rack behind the screen, and her underwear on another hook. She returned to the couch wearing only the robe and a pair of plastic slippers. "Good! Now, please lie back on the couch and relax. I need to make some measurements." He opened the bottom three buttons on the front of her robe, exposing her womanhood. "Now, please place your feet in the stirrups, and I will measure your vaginal dimensions." Lucy complied nervously. "Don't worry, this won't hurt. I am just going to insert an expandable cylinder to measure a diameter for the device. All my devices are custom-made, to fit the subject carefully and to avoid cross-contamination. I would not do this if you were still a virgin." (One of the line-items on the consent form.) He took a piece of 0.010-inch Mylar sheet, about 10 inches wide by 8 inches long, and rolled it up into a tight cylinder. He inserted it carefully, and then allowed it to expand naturally. He applied Scotch tape at the top end to hold the dimension, removed it carefully, and added another piece of tape at the bottom to hold the cylinder together. He then re-inserted the cylinder, and picked up a polycarbonate plastic caliper. "Just measuring the clearance from the vaginal opening to the clitoris", he explained. One more dimension went into the notebook.

"Finally, I need one more measurement. This may be a bit uncomfortableplease tell me immediately if you feel any discomfort. Kindly roll over onto your stomach, and put your feet back into the stirrups." Since he had been careful not to hurt her, Lucy complied again. He slipped the robe up over her hips, spread the stirrups and her ankles farther apart, and went to one of his cabinets. "I need another dimension, but this needs to be done with more substantial insertibles," he explained. "I'll start with a small butt-plug, and then try some larger ones. When it starts to be uncomfortable, please tell me immediately and I'll stop". He pulled out the sterilized bag (previously autoclaved for safety) and a tube of lubricant. "Here is a thin one", he said, and it slipped right in. He pulled it out slowly (“Not bad”, Lucy thought). He dropped that one into a cleaning bucket and increased the diameter by 2 mm. "Is that OK?" "Feels nice." "Good!" Again, he removed it slowly and dropped it into the bucket for later cleaning and sterilization. The third one (another 2 mm larger) did not go in so easily, but she said it didn't hurt. Removing that one elicited a soft moan. The fourth one, however, almost three-eighths-inch larger than the first one, caused her to flinch half-way in, and Lucy asked him to stop. He immediately stopped pushing and carefully removed it.

"Excellent, you were most co-operative and deserve a treat! Come back in ten days, and we shall fit the actual stimulator for your testing and, hopefully, acceptance!" He helped her off the couch, removed the robe in a most gentlemanly manner (as if removing a lady’s coat), and paused to appreciate the view. Lucy quickly ducked behind the screen and dressed. When she came back, he kissed her hand in an old-school manner, and escorted her upstairs. "If you need the washroom, it's down the hall." "OK, be right back." Once inside, she quickly inspected herself in the mirror and found no damageher virginity was long-gone before this. She checked that her clothing was straight, combed her hair quickly, and went back to him. He thanked her again, reminded her to come back in ten days, and locked the front door behind her after she left. Lucy walked away from his door with a smile on her face.

Five days later: Girls talk, you hear things! Her shy friend Susan had noticed a change in Lucy’s demeanor, and wormed the secret out of her. Another case of excess curiosity, but Susan could not help herself, either. And so, she presented herself at the old man’s door, and he politely invited her in. In his foyer, despite his friendly greeting, she was so scared that she could not speak for almost a minute. He asked her quietly what he could do for her, and she finally responded that she was intrigued by what her friend had told her, but was nervous due to her virginity. "A true maiden, in this depraved millennium?" he marveled. "That deserves respect and requires careful treatment. I would never compromise a damsel's honor! Please follow me." He led her downstairs to the cellar laboratory.

"I don't know what your more experienced friend told you, but for a virgin we do not make any measurements nor use any equipment that would require penetration. I believe in the old-fashioned definition of maidenhead. The apparatus is therefore simpler, and not so customized to fit the subject. Therefore, I can have it done in about five days. First, you must show me your ID and sign this release form. Then, please undress, put on the gown you will find behind the screen, and make yourself comfortable on the couch." He indicated the medical couch. Susan nodded silently, did the necessary formalities, walked behind the screen, and came out in the paper gown and plastic slippers. He helped her onto the couch. He dipped the polycarbonate plastic caliper in alcohol before making some measurements. "If I accidentally pinch you, please tell me. There is no intent or reason for discomfort." First, he measured her nipples in their relaxed state, checking both vertical and horizontal diameters, and the diameters of her areolae. "Could you stimulate yourself to make them erect, or would you prefer I do it?" She reached for herself, slowly pinched and rolled the nipples between two fingers, until they stood erect. He then re-measured the nipple diameters, and how high each protruded from the areola. All these numbers went into a formal leather-bound notebook on a page dedicated to her (the previous pages had the more detailed set of Lucy’s parameters).

"Thank you. Now to the center of your responses." He carefully re-rinsed the caliper jaws with isopropyl alcohol, and then measured her clitoris. "Again, could you stimulate it?" She moved her right hand down to her womanhood and worked at it until she started to breathe more heavily. "Please pause", he asked and repeated the measurements of both diameter and height. "You may resume now", and Susan continued until she climaxed. He handed her a clean towel and thanked her for her co-operation. "I would like one more measurement. May I probe your anus?" She had heard about that, and decided to comply. He repeated the procedure used on Lucy, using the same set of plugs that had been carefully cleaned and autoclaved since those measurements. Again, Susan’s dimensional data were recorded in the notebook.

"One last thing. I understand you are on the swimming team?" (He had his own sources of information.) Susan nodded. "During the next two days, please go to the shop and purchase a new racing suit. It should be a tight fit, but one size too large in both the bust and waist: you will understand why in due time. Don't spend too much money, since we shall need to cut openings for wires." She gulped at that suggestion, but agreed to buy it. "Please come back in five days, and we shall fit the equipment and try it out." He helped her up from the couch, politely helped her remove the gown, sighed at the beautiful sight in front of him, took her hand, and led her back to the screen. Impulsively, Susan kissed him before ducking behind the screen and dressing. She was now in a hurry to leave, and was slightly mussed as she left his door with a secret smile on her face.

On the tenth day, Lucy returned, and he showed her down to a second room in the cellar. This time, he was wearing a white laboratory coat over burgundy silk pajamas and leather slippers. She undressed behind a screen and came back nude except for the slippers. “Now, please grasp the overhead bar and spread your legs apart. I’ll carefully fit two inserts into you, fore and aft,” he said, as he took a plastic box down from a shelf. She complied, and he inserted two silicone plugs, each into the appropriate orifice. For the rear plug, he used a mixture of KY lubricant with EKG conductive gel. “I started with commercial vibrators,” he explained as he carefully fit the devices, “but I needed to replace the cheap motors with modern Swiss instrumentation-grade brushless devices with neodymium-boron magnets, for more power in a slimmer package. Now, we add a restraining harness to hold the two plugs in place, and then add a third module.” The third module, roughly circular, was located by a flat nylon plate that indexed from the front plug, to fit accurately on her clitoris. The harness started with a wide waist belt; a tapered front strap snapped in place on the back of the belt and was buckled tight at the front, underneath her navel. The strap held both the front and rear plugs into their locations, and pressed the clitoral device against her. “Now for the wiring,” he continued, and snapped three plastic-housed electrical modules onto the belt, two in front and one in the rear, and connected short flexible cords to the three devices. “Technically, the rear plug is both a vibrator and the electrical common for the electrodes on the front plug and cap. The two front devices vibrate, and the compound motion of the clitoral stimulator involves an ingenious Geneva mechanism. I could patent that, but the world is not yet ready for such a device. Now I must calibrate the settings.”

He started the vaginal vibration, and Lucy immediately felt the pleasant sensation. He increased the speed, and she started to moan softly. “Tell me if you feel any discomfort,” he instructed, and she finally said “Enough!” at a setting of 8.5 on the dial. “Now for the rear,” he announced, stopped the front plug and advanced the control on the rear plug. “Again, please tell me of any discomfort.” Lucy was getting into this, and did not object when the knob reached 11, its maximum value. He backed the control off a few notches said “Hmmm, you like that, don’t you?” and entered values into his notebook on her page. Then, he shut down the rear control and moved to the stimulator. “Now, if I continue with this one, you will reach orgasm, and it’s too early for that. Therefore, please indicate the start of your pleasure, rather than your tolerance. It will moisten you, and that will improve coupling to the electrodes.” (“Electrodes?” she thought, “This is starting to sound like a horror movie. At least I’m not tied down.”) He advanced the third control to about 3.0, and she nodded when she felt the start of female pleasure. He kept it at that intensity to moisten her, and then surprised her with a press of a button. “Oh!”, she jumped as the mild electrical shock hit her sensitive areas. “Too strong?” he asked and hit her again with a milder shock. “I can take the second one, I think,” Lucy said, “What was that for?” “All in good time, my dear. Now, I will power down and we shall shift you to the frame.”

He held the cables away from her, and backed her towards a free-standing X cross mounted about four feet from the back wall. He helped her climb onto adjustable foot rests roughly one foot off the floor, secured her ankles to the cross, and then secured her wrists to the upper part of the cross. He adjusted a headrest behind her head and neck to support her, and let Lucy lean back. A final strap was a simple padded belt around her waist through loops near the vertex of the cross. He moved the cart with the controls to her left, and re-connected the cables. “Please wait here; I’ll be back in five minutes” he ordered, shut off the overhead lights, and left the room.

Mr Wizard, part 3

During this process, Susan was sitting in the next room, the laboratory she had visited earlier, but could not hear through the soundproof walls. He had shown her where to cut vertical slits on the front and back sides of the diving suit, and she had done that carefully with a sharp scissors. She then undressed and waited for him. After he left Lucy on her frame, he knocked and came in. “Good work”, he complimented her. “Before you put the suit on, we need to instrument you front and back.” He had her lie on the medical couch face down, and inserted the rear plug using the same lubricant mixture; it was similar to Lucy’s but dimensioned for Susan’s exact anatomy. She rolled over, and, in front, he inserted nothing into her vagina, but added a cap over her clitoris, carefully fitting the active part over her bud. He added an X of surgical tape over the cap, and asked her to stand up carefully. “Now, we put on your suit. I shall pull the cables through the slits. Please be careful not to disturb the units.” Susan put the suit on halfway, and he asked her to snug the suit bottom against the units after he had threaded the cables through the fabric. “In place of a vaginal stimulator, we shall use these two custom-fit nipple devices”, he explained as he put them over her breasts while she stood in front of him, and secured them temporarily with tape. “Please fasten the top straps of your suit, and tighten them.” He threaded the breast cables out the neck of the suit. “Now, carefully lie back on the couch with your feet in the stirrups.” The stirrups were at their lowest elevation, and he used padded straps to hold her ankles to them. “Arms up”, he ordered, and secured her wrists to eyebolts at the head of the couch. He fastened a safety belt across her waist, and a second around her chest just under her breasts. The three control modules were snapped to the waist belt, and connected to the units. “Now for a short ride!” and he opened the door and wheeled her into the next room. When the lights came on, they both gasped when they recognized each other. “You dweeb wannabe! What are you doing here?” Lucy demanded, and Susan shot back “You slut? You think I need to be in your clique to contribute to science?” “Now ladies, none of that! Both of you are going to participate in a very important experiment. If you both follow orders carefully, not only will no one be hurt, but all three of us will enjoy this!”

He carefully wheeled the couch so that Susan’s feet went past Lucy under the X-frame, and locked the casters. Each young lady had a clear view of the other from thighs to face. The sight of the other seemed to bother each of them, and they struggled against the straps, but he had them securely bound. “Calm down!” he ordered, “or I will have to gag you.” He adjusted the room lighting so that the top half of each woman was illuminated, but the rest of the room was only dimly lit. The cart held enough equipment for both subjects, and he connected Susan’s apparatus to a second set of controls. He went through a quick set of tests of her responses, and then described the protocol.

“I am going to give each of you two pushbuttons, which I shall tie loosely to your hands so that you don’t drop them. The left (sinister) hand’s button will give a painful stimulus to your friend, but the right-hand button will give her a pleasurable stimulation. I have the intensity controls and an emergency-stop switch, so this cannot get out of hand. Of course, the other has the matching switches, and will react to your activity as she sees fit. I’ll start by giving you the switches, but I won’t enable the apparatus until you are both configured. Over the course of the experiment, I may vary the nature and intensity of the stimuli, but the location of the pain and pleasure buttons shall remain invariant.” Each push-button was contained in a hand-sized pendant shell, which he taped to the appropriate palm. He closed the fingers around the shell, and wrapped Velcro around the fist, leaving the thumb in a good position to push the button. Light flexible cables went from each of the four switches back to the equipment cart. With all four hands fully equipped, he went back to a comfortable office chair behind the cart and turned on the master switch. Nothing happened immediately, but after a few seconds Lucy could not resist hitting the nasty button. Susan yelled, and immediately pushed her left-hand button until Lucy released hers. “Lesson one!” he shouted, “can you try the other button?” Lucy hesitated, but gave Susan a quick right-hand shot. Susan jumped, but did not make a sound. Lucy held it down longer the second time, and Susan started to breathe heavily. While Lucy’s second salvo was in progress, he prompted Susan to try hers. Susan complied, but gave Lucy a series of short bursts. Meanwhile, he started to readjust the master controls, changing the focus of the mechanical stimulation from Susan’s clitoris to her nipples, and from Lucy’s clitoris to her vagina. Susan sneaked in another left-hand jolt, to which Lucy retaliated, and the pleasure stopped for a while, but Lucy was the first to resume the right-handed action and Susan quickly followed suit.

He had other tricks, however: he jolted both of them to get their attention, and ordered them to pause. “You are both in my power, but I want to guide you to an optimal conclusion. The first important test is to compare slow-but-steady stimulation to intense-but-intermittent stimulation. In the first test case, I will maintain a steady pleasure stimulation, disabling your thumb buttons, and time your response to orgasm.” Setting the control switches, and starting from a relatively low intensity, he started to stimulate them, while slowly advancing both clitoral intensity controls. He had started two digital timers running at the start of this procedure. After increasing intensity the intensity for two minutes, he reached what he considered a safe upper limit, and continued at that rate. By now, both women were breathing heavily and moaning. He saw Lucy start to jerk against her bonds at the four-minute mark, and she screamed aloud thirty seconds after that. Lucy’s scream seemed to trigger Susan, who came promptly thereafter. After each woman climaxed, he reduced her stimulation back to a low level for 30 seconds, and then ramped it down to zero. After 30 seconds to relax, he regained the attention of both by zapping them (medium setting) twice. “Did you enjoy that experiment?” he asked, and both ladies murmured “yeah!” Before proceeding, he brought a squeeze bottle of water for each and gave them a drink. He checked their hands and feet to watch for circulation, and stroked each of their faces gently with the back of his right hand. “Science is fun!” he exclaimed, “shall we continue?” “Right” and “Please” were the responses from Lucy and Susan, respectively.

“For our next experiment, you two shall start on each other with your right buttons, but I will disable your left buttons, leaving that stimulus to me. Later, I want to see how much painful stimulation is required to stop the pleasure. For that purpose, I need to monitor your respiration.” He then inserted a gag into each mouth with a long transparent flexible breathing tube attached. The tubes connected to an airflow-monitoring device that read out on a two-channel paper chart recorder. The recorder bed was directly in front of him, so he could annotate the chart with a felt-tip pen. He started the monitor, noted the start point on the chart, and alerted the subjects. They each pushed their right buttons, and held them down. He slowly ramped up the intensity as before. When their respirations had increased measurably on the recorder, he told them to hold their buttons tightly. At random intervals, he gave them simultaneous jolts, noting those times on the chart. Their respiration rates slowly increased, with the gasps from each jolt indicated, as the stimulation progressed. This time, Susan started approaching climax first, so he watched her carefully and gave only her a strong jolt, which induced a big gasp and her respiration reverted back to an earlier rate. Lucy noticed this reaction and her excitement built quickly; he was not quick enough on the jolt button and she reached an intense orgasm while Susan regained her plateau. He quickly throttled back on Lucy and accelerated Susan to her climax. Again, he shut off the stimuli and watched both subjects’ respiration return to normal. He stopped the chart, and removed the breathing gags.

“Enough for today!” he announced, as he disconnected the wires but left both women secured. He went first to Lucy, and then to Susan to check their extremities, kissing each tenderly on the eyelashes. “Did you get what you came for?” he asked. Lucy spoke first, and replied “That was a trip! How many of us have you done?” He did not answer that, but Susan said “That was far better than anything I have done by myself!” He first unbound Susan, and helped her out of her suit. He then unbound Lucy, and they stood next to each other, still wearing their apparatus. They held still while he extracted and untaped the probes, carefully putting each woman’s gear in zip-loc bags in separate containers for cleaning. Fully naked and unwired, they stood in front of him. “Now, we must all be friends. Please shake hands!” They complied. “Now, kiss each other on the cheek”. Again, they complied. “Now, kiss each other properly!” As they started, he encouraged them, “Tongues!” The two women were responding to each other now, their earlier animosity forgotten. Spontaneously, they reached for each other’s breasts and continued their kiss. Finally, they broke their clinch and turned to face him.

“You two have made a wonderful test case, and I hope we can continue the experiments. I did not wish to go very long today, since this was all new to you and possibly shocking. Next time, we can get both of you very comfortable, and experiment with both channels to see if you can get erotic stimulation from the pain channel, properly applied. Are you willing to continue?” They agreed eagerly, and scheduled their next meeting for the following week. “I shall clean the equipment. Susan, please launder your suit before next time. Lucy, did you have any discomfort from the vaginal probe?” Lucy shook her head. “Also, in later trials we need to use the anal stimulator more, not just as a return electrode. You two have a lot to look forward to!” They smiled, and kissed him suddenly from both sides. He wrapped his arms around them, and they coalesced into a group hug. He handed them towels and wet washcloths, and the two women went back to dress. Meanwhile he carefully flattened the front of his pajama trousers.

He brought the pair upstairs to the kitchen, and poured iced tea for the three of them. Susan’s shyness returned, but Lucy seemed less nasty than before. The girls finished their drinks in silence, and then departed the house, smiling.
