An Edge Case

“An edge case,” Doctor McGee sighed, on the verge of fed-up, but reeling herself from that unhelpful precipice. She took a sip of her dark coffee to console herself a moment. You and your colleague were sitting together in the middle of the main lab, looking up at the large monitor with the big calendar showing all the blowjobs you needed to get. “Just what we need,” the Doctor went on sullenly. “With this complication to Batgirl’s condition, her addiction will likely progress much faster than we first anticipated. She’s going to need more of your cum.” Another long sigh, this one stretching with tiredness as she rolled back her shoulders. She nearly brushed against yours, with how close she was sitting next to you. “They’re all going to need so much of your cum,” she said, exhausted on your behalf.

“I could increase my supplement intake,” you suggested helpfully. Hopefully. “I know we’re already optimized to a certain degree but I think my increased workload might call for some further... reoptimization.” The other scientist nodded, but didn’t seem all that convinced.

“It’s not just increasing the volume of your cum output that we have to worry about,” she said. “You cock is already… sorry... your penis… it’s undergoing constant friction and it’s only a matter of time before you hurt yourself. Heaven help us if that happened.” She even seemed to wince for you at the end of her warning. Doctor McGee’s proprietorship of your dick made you feel… a certain way. There was a lot more ‘we’ and ‘us’ about the whole endeavour now, you noted. Before you could dwell too much on that warming thought the Doctor remembered something and sat up, then got up. “Oh that’s right, I almost forgot,” she muttered, moving over to a cupboard to investigate its contents. You watched her pull down a couple of bottles then bring them back to the table as she returned to her seat.

“What’s all this?” You picked up one of the bottles, but was distracted from reading the label when Doctor McGee started pulling your shorts down again. Your body seemed to have an instinctive, automatic reaction to feeling someone’s fingers on your waistband now. You simply lifted your butt from the seat and let her slide your shorts down to your ankles before sitting again. The Doctor decided to take the shorts all the way off though and casually put them aside on the console. The fact that she hadn’t given you so much as a word of warning before exposing your genitals really brought to bear the notion that she felt your cock was hers to do with as she saw fit. You quickly began to rise to attention at the familiarity of it all.

“I already noticed some redness when I was examining you up close,” she said, without adding ‘while I was getting you hard’. That very good, very recent memory had you already standing stiff. Her hand went to you, wrapped around the middle of your shaft before she slid down to grip you by the base. “I have a few lotions and moisturizers,” she said giving you her professional, patented tugs to get you harder. “Should help with any dryness and unwanted inflammation.” She continued to patiently stroke you to get you swelled the way she did wanted and you could only sit there and ‘endure’ it. Your brain was hardly working, almost convinced that she was simply doing this out of medical need. For your well-being. She let you go, your cock already hot iron, and picked up a bottle and squirted some viscous blue fluid into her palm. She applied this for you of course, spreading it from your head down to the base of your dick with her hand, coating you in the cool, slick substance.

It started to foam as she rubbed more vigorously, and you could feel the very light bubbling sensation across your skin as she scrubbed it in. She made it a point in avoiding going too high, her fingers almost squeezing to a stop as she reached your head on each up stroke. As she went down to massage some of the dripping suds into your balls she reached over with her free hand for a cloth, a stack of which were in a small square box. It was used to wipe the runny foam off of your junk, and she did so efficiently and diligently, making sure not a single bubble remained. Your cock bobbed and flexed from the firmness of her brushing swipes. She wiped her hand with the cloth to clean what remained from her own skin and you both eyed your wobbling erection, which for a second seemed slightly paler. The air felt a bit prickly around it. “That was a cleanser,” she explained now, which made a sort of sense to you, skincare routines only something you could guess at. “I’ll use some essences and serums next. ”

She didn’t expound on the whys and whatfores. You didn’t much care for further explanations to be honest. You just wanted her to keep jerking you off. Doctor McGee didn’t waste much time

spurting a lighter, more watery substance onto hand next, then began to slather your cock with it. This was altogether much cooler, though perhaps your dick was just superheated now because of the doctor’s cleansing handjob. The wetness was pleasant and more slimy and she covered every inch of you until you were shiny. It seemed to air dry rather quickly while she wasn’t actively applying it, then she spilled some more cold liquid directly onto the tip of you, sending a wonderful shiver through your body, and masturbated you some more, patiently and slowly and making sure you really absorbed this essence of whatever it was.

“A couple of creams and lotions and we’ll be done,” Doctor McGee said, and you looked up at her perfect pokerface, but you could detect something there. Perhaps a smile around her eyes. She poured a generous helping of creamy white cream onto her cupped hand and returned to servicing your now well massaged and throbbing cock

You let out a breath as she worked the cream in, your obvious enjoyment not a concern. That this felt amazing couldn’t be helped, you both knew. It was your dick she was rubbing after all. She stroked the thicker agent into your skin, and aside from the erotic pleasure it did have a sort of smoothing effect as well. As if you could already feel it working. The grip of her hand was unnecessarily firm, the lubricating cream making her need to squeeze you more so that she could give you the proper friction. You suspected she only needed to be applying it gently to your skin rather than make it feel so damn good. It felt so fucking amazing, and your breathing quickened. She stopped before anything went too far, and aside from your dick looking a bit more tumescent than before there was no real evidence of the cream at all, now absorbed into your skin. “Almost done,” she said, noticing how hot and ‘glowing’ you were. You could feel a tinge in your cheeks too. “How are you holding up?” she asked, only slightly concerned. She knew you were getting the best manual dick treatment ever, a glimmer in her eyes.

“I’m getting close,” you warned her, ever the diligent doner. “We better be careful I don’t blow a load without a patient to swallow it.” The Doctor bit her lip at how direct you were.

“We definitely don’t want that,” she agreed flatly. “We can’t let any of your cum go to waste.” So she left it at that then picked up the smallest bottle from the table, about two inches high and as thick as a tube of lipstick but filled with a clear liquid. “This oil should help your skin stay hydrated,” she said, wiping her hand on her skirt before dribbling said oil into it. She moved her fingers over to your dick, letting some of the oil drip off her nails and onto your skin before grasping you again in her mildly needy way. This was probably the best part of the whole process, you realised, as her soft hand started gliding up and down your achingly hard penis. Perhaps all of that moisturizing had something to do with it, but her hand felt even silker than before, and the lubricating oil seemed to let Doctor McGee find the perfect friction point and warmth was spreading through you in lovely pulses.

“Oh wow,” you couldn’t help moaning, and she smiled at your reaction openly, continuing to stroke your now glistening cock. You felt the urge to let your friend and colleague know just how incredible she was at this… it just seemed wrong to not give praise where praise was due. “That feels so amazing Tina,” you told her, and the way she looked at you, with a hint of pride under her raised eyebrows, had your blood pumping. “I think if I came now it would be my biggest load ever.”

She chuckled at your compliment while never faltering in her stroke. She conceded with a cute head tilt, her raven hair flowing over her shoulder. Then she seemed to have an idea.

“John I think you might be onto something,” Tina said, a few blinks causing her to stare off into the middle distance, before she switched her focus back to your burning gaze. “Generally the longer an extraction section goes the more cum can be delivered per dose, but in most cases the increase in volume is marginal. But you might be a bit different.”

You listened intently, also blinking a few times but that was mostly caused by the rapidly building pressure you could feel under her practiced pumping. “I told you I was crunching some numbers before. I was seeing if we could optimize the extraction times with each patient to try and get the most out of you for each dosage… Some of the results were promising, though not too significant if I’m being honest. But I hadn’t considered a different approach… a method where we extended the preparation time instead. Substantially.” You weren’t quite sure what she was getting at with this, but for obvious reasons it was hard to use your brain right now. Surely she could feel the twitching of your dick in her hand as you started to clench.

“I’m getting really close now Tina,” you said, breathy. The woman seemed too caught up with her new idea to fully register your cautionary tone.

“You’re an edge case too,” she said instead, almost admiringly, not slowing down her stroke. “And I think edging might really work well in your case. You’re familiar with edging I assume?” Now you started to get it, and you gritted your teeth and nodded. She seemed happy that she didn’t need to explain things too much, but she went on anyway. “Your hyperspermia, coupled with how quickly you can replenish your reserves, leads me to believe that with proper edging technique we could increase your cum production much more significantly than doing so with any normal donor. Any normal man. Your scrotum has already grown in size, markedly larger now than when you first arrived. You’ll be storing more cum than before, your body more accustomed to the regular release of semen rather than reabsorbing it. So we just need to keep masturbating you as close to the point of ejaculation as possible and stop. Give you a minute, then build you up again and-”

“Stop,” you cut in. She nodded, not minding that you finished her sentence in such an abrupt manner.

“Exactly, if we do it long enough I believe the results will-”

“Stop,” you repeated urgently, your hands balled into fists at your sides. She looked to you in confusion, still stroking your cock while you clenched with all your might, your body unable to move for some reason. You were about to explode. The doctor still looked puzzled and was not letting up.

“What are you-”

“STOP!”
