16: Side-Effects

Relapse

"So, Mark, what brought you to me today?"

I needed help.

"It says here you're suffering from melancholy, hyper-sexuality, and countless perversions."

If the straightjacket fits…

"Based on your medical history and initial tests, I believe these symptoms are being caused by an excess of semen. When was the last time you had an orgasm?"

The jacket held me snug in my own embrace. The straps between my legs were pulled tight, squeezing and framing my naked cock. A short chain joined together thick leather cuffs around my ankles. Another chain from the back of my collar held me to the wall of my padded cell. A leather strap in my mouth kept me from speaking. Biting. There was no escaping.

"No matter. Rest assured, Mark, your condition is perfectly treatable. We can start immediately."

Doctor Sienna was a foreboding figure. She loomed over me in six-inch heels. The harsh, artificial lights glared off her latex uniform - blood red thigh-high boots and matching arm-length red gloves, a white body suit with a dramatic red cross around the ample chest and down through her crotch. She smiled at me with a practiced, professional warmth.

"Nurse Sophie will be assisting me with the procedure today."

Sophie stepped into view from behind the Doctor. She wore a pink latex dress with a small cross-shaped cutout over her cleavage. White latex, wrist-length gloves, and white fishnet stockings. The dress was tight around her thighs, making her sway her hips dramatically as she stepped about in her pink platform heels. She looked stunning.

"Ah," said the Doctor, looking down at my crotch, "I see you're ready for your treatment. Good. That will save us time." Doctor Sienna unlocked my chain from the wall and pulled me up onto my feet. "Let's bring the patient to the operation room," she said, handing the chain to Nurse Sophie.

I hobbled and stumbled as she led me to the adjacent room. In the center was a metal table, surrounded by mysterious devices and arcane equipment. My mind was racing, imagine what they might all be for - how they might be used on me.

Together, Sophie and the Doctor helped me up onto the table, putting me on my back. Sienna took my neck chain and locked it down to the table, holding my head in place. Thick leather straps were pulled up and wrapped around my jacketed arms, then pulled tight to the table, holding my body in place. She removed the chain from between my ankles, then she and Sophie lifted my legs up, spread them, and locked them into stirrups, holding them in place. I was immobile. I was exposed.

"Comfortable?"

Physically… Yes, surprisingly. Emotionally…? I nodded. 

"Good. That's what we like to hear, isn't it nurse?" 

Sophie let out an excited giggle.

"Okay. The procedure we will be performing today is called an 'electro-stimulated semen extraction'. Do you know what that is?"

I could make a pretty good guess. My heart skipped a beat.

The Doctor revealed a short metal baton, tapered like a butt plug, a wire coming out of one end. "This is called an 'e-stim probe', and what we're going to do today is insert this into your rectum. We'll turn the device on, and it will apply small, targeted electric shocks to your prostate. This will stimulate the release of ejaculate. The procedure will usually take around 5 to 10 minutes."

I felt as if I was already filled with electricity. Ten minutes of getting shocked in the arse? Inside the jacket, my fists were clenched at the thought. I caught sight of Sophie giving Doctor Sienna a nervous look. The Doctor placed a hand on her shoulder and smiled.

"Do you consent to the procedure as I've described it, Mark?"

I nodded. I took a deep breath, collected myself. "Ee-esh." I was ready for my treatment.

"Very good. If at any time during the procedure you wish to stop, just give two slow blinks. Can you try that for me?"

I blinked twice.

"Perfect, just like that. Now, Nurse Sophie, I want you to pay close attention to Mark. Some patients (usually men) are too stubborn to admit when they're overwhelmed. So I want you to watch out for subtle signs, such as wincing or a clenched jaw. Don't call attention to it - we wouldn't like to hurt the patient's pride, after all - just ease off a little. Good?"

"Yes, doctor."

"Good. Let's begin."

Remission

"We're going to start by applying conductive gel."

Nurse Sophie approached, trying to hold an air of professionalism, but barely hiding her excitement. She stood between my legs, and squeezed the bottle of gel, letting it drip onto my exposed hole. I shivered as the cold hit my skin. She rubbed it around, into me. I tried not to clench.

"Don't be shy, Nurse. This gel will help to ease the insertion of the probe, as well as conduct electricity from the probe. Use as much as you need to."

Doctor Sienna had meanwhile been lubricating the probe, which she now passed to Sophie. "Now, Mark, you're going to feel some pressure…"

Sophie pressed the probe against me, tried to push it into me. "I'm feeling some resistance, Doctor?"

"That's fine, just keep applying steady pressure." Then looking at me, "please try to relax, Mark."

The metal was so cold. I closed my eyes and took a long, slow breath, letting my body relax. I felt myself stretch… and contract. A shudder shot down my spine. It was inside me.

"Thank you, Nurse." Sophie grinned with pride at the praise.

From under the table, Doctor Sienna pulled out a hard, transparent, plastic tube. Inside it was a rubber membrane, and attached to the top was a thin rubber tube, which ran under the table. "Next, we're going to insert your penis into this 'semen collection apparatus'. Nurse Sophie will need to apply more of the gel to your penis. This will help us to insert your penis into the collector, and create an air-tight seal."

Sophie lovingly caressed and massaged my already rigid cock with a palmful of gel. I was already so worked up, I had to bite down on the strap to keep from blowing the treatment. She then helped to guide me into the snug tube.

"Once the machine is turned on, you will feel some suction. The purpose of the device is to collect the semen that is released by the shocks, so that it can be safely disposed of."

Doctor Sienna talked Sophie through how the machinery worked - this button to start the suction, that dial increases the strength of the shocks, and be careful not to turn it too high, "it is poor Mark's first time, after all."

Sophie's face took on a familiar grin, "right, Doctor."

"Alright, Mark. I have to step out to see to another patient. But I will leave you in Nurse Sophie's very capable hands." 

And just like that, we were alone. I'd be lying if I said I didn't feel nervous. Not that I didn't trust Nurse Sophie, but--

"Ready?"

I nodded. And with a click of a button and a slurping sound, the suction device came to life. It ran in a pulsing pattern. The suction came on - the membrane tightened, grasped my erection, the tube pulling me in deep; then relaxed, loosening its grip. On and off it repeated, like a mechanical blow job. God, it felt so good.

Then the shocks started.

Each shock stung, making me clench against the probe. My whole body might have spasmed and folded in on itself, I might have writhed about, if the tight restraints had allowed me an inch of movement. I was biting down hard on the leather strap, moaning with each jolt.

Nurse Sophie watched my performance with a keen, analytical interest - watching every contraction of muscle, every twitch of my eyes. Her expression was almost dispassionate as she made micro-adjustments to the machine controls.

Then the probe started to have its effect. With each zap, I release a portion of cum, which the device on my dick hungrily sucked away. Each time it felt like an orgasm, or… half an orgasm; not a usual wave of ejaculations, but a single burst with each shock.

Sophie walked about me, taking me in from every angle. She idly ran a finger along my bare leg, and flinched when a shock conducted through to her hand, then giggled in excitement. "This thing's amazing!" she said, "I didn't know you could cum this much, ba-- Mark."

After my tenth, or… I dunno. It was hard to keep track. Hard to keep track of time, or… mind or… How long could this go on? Five to ten minutes? But how long had it been. How many more times would I cum before she was done with me? How much more cum did I have to give? How many orgasms would it take to cure me?

Sophie leaned in close and whispered in my ear, "I'm having so much fun." Then I felt her lips pressed against my forehead.

"Nurse!" The Doctor returned, and she was not at all pleased. "This sort of conduct is unprofessional, and highly inappropriate."

Sophie stood bolt upright, her hands gripped behind her back, like a soldier being dressed down.

"I'm afraid you'll have to face the disciplinary board."

Remedy

Thwack

"Uhn… sorry Doctor Sienna."

The disciplinary board was really more of a paddle. It was wrapped in leather, with small aerodynamic holes in the shape of crosses that left an impression on Sophie's bare arse.

Thwack

My beloved nurse had been stripped of her uniform, and was now over the good doctor's lap. Her face was flushed, and when she received the board's discipline, her back straightened - she bucked, and let out a yelp.

Thwack

I was catatonic from my own treatment, in a daze after what felt like hundreds of orgasms. An endless barrage that had turned me into a puddle, my restraints the only thing helping me to hold solid form. All I could do was watch as Sophie took her punishment.

Thwack

Fuck, it was hot.

"It would seem you're just as sick as our patient. Perhaps you require treatment as well, hmm?"

Thwack

"I believe your condition is being caused by a 'wandering uterus'. It's quite common in young women, and the treatment is simple enough. We will use a special machine with a rubber probe. The probe will be inserted into your vagina. The machine will then move the probe back and forth in a steady rhythm, and this will force a mechanical realignment."

Sophie's eyes went wide. Was she thinking what I was thinking? That it sounded like the Doctor was describing a fucking machine.

"Do you consent to the treatment as I've described it?"

Sophie seemed to hesitate at the question. I found it hard to imagine her agreeing to such a treatment; to being put into such a submissive position. The Doctor leaned down towards Sophie and whispered something I couldn't hear.

"Yes… " Sophie finally conceded, "I consent."

"Thank you. Oh, I forgot to mention, we'll need to strap you down for the procedure - tight. We wouldn't want you to move while the machine is running and end up misaligned."

Sophie was wrapped up in a straightjacket of her own and gagged, and set aside while the doctor helped me down from the operating table. She guided me to the wall, positioned with a good view of the operating table. She helped me down to my knees, and as she locked my collar chain to the wall, she said quietly, "remember what I said about watching for subtle signs?"

The Doctor led Sophie to the operating table, and strapped her down like she had done to me - her ankles raised and spread, her cunt exposed, ready to receive her treatment. The Doctor wheeled over the device, a box with a long metal arm, tipped with a silicone probe that looked suspiciously phallic. She aligned the device between Sophie's legs and locked its wheels, then rubbed a generous amount of lubricant gel over the probe.

Sophie jolted, as the Doctor guided the cool tip of the probe between her lips, her chest rising as it inched its way deep inside of her. She then let out a moan as the probe retreated again. Slowly, the machine repeated, in and out, picking up its pace with each stroke, every entry seeming to catch her by surprise. 

I shifted about, trying to find a comfortable position, trying not to put pressure on my still-sore backside. The sight of Sophie's treatment was incredible. Despite my own treatment, I was rock solid; as if I had any orgasms left to give. I felt like my cock was going to burst and shatter into a million tiny pieces. Saliva dripped helplessly from my gagged mouth.

The machine had reached an inhuman pace, and with it Sophie's moans had hit an un-heard-of pitch. Was she orgasming? Had she already orgasmed? It was impossible to tell. The machine seemed to be holding her at a perpetual moment of ecstasy; panting and straining against her bonds, her jaw gnawing at her gag, a… tear… dripped down her cheek.

I saw Sophie's eyes narrowing, held ajar by her stubborn pride. I jerked my shoulders, rattling my chains, and looked at Doctor Sienna. She met my eye, and I gave her two slow blinks. The Doctor smiled back at me and nodded.

The Doctor turned back to the machine controls. "Looks like your treatment is almost complete, Sophie." The arm's movements steadily slowed. Sophie was breathing slow and heavy, trying to catch her breath. Her hair was wild, sweat dripping from her face. She closed her eyes tight.

"You both did really well. Let's get you both back to the cell to convalesce."

Recovery

Sophie laid on the floor of the padded cell beside me, still wrapped up tight in her jacket. Her arse was still visibly pink from its disciplining. From time to time, she would flinch as the small movements of her legs brushed her tender cunt, still hyper-sensitive from its treatment. Her back was turned to me.

"What did Doctor Sienna whisper to you?" I asked. "Before you agreed to the 'treatment'."

Sophie was silent for a moment. Then let out a sigh. "We'd been talking… while she was helping me into that latex uniform (not easy, by the way)." Her body tightened up, her knees pulled towards her chest. "I was telling her about… you know. And how it had been a while since we… And she said it might be good for me to experience things from your perspective. She said it might help you too, if you saw me like… that."

I shuffled towards her, as close as the collar chain would allow me to get. My lips brushed her neck, "thank you… for doing that for me."

"And… I mean…" She shook off her moment of vulnerability with a forced laugh. "How many chances do you get to try a fucking machine?"

I laughed. She had a point there. I might have been tempted myself, if my arse hadn't already been zapped into oblivion. "You never know," I said, "this doesn't… have to be a one-time thing…"

She rolled to face me and gave a giddy smile. "I love you SO much, baby. Thank you for agreeing to try this at all." She shuffled closer against the slack in her own chain until our mouths met. "It really was fun, huh?"

"How sweet." Doctor Sienna stood at the cell door with a condescending smile. "You two really are a perfect pair."

The Doctor unlocked us and helped us out of our jackets and bonds. And with that, our session was over.

"I'm writing you a prescription for one orgasm each, to be taken daily. We'll start you at two weeks - if you're still experiencing symptoms after that, please don't hesitate to make a follow-up appointment, and we'll go from there. Okay?"

I don't know if our treatment was NHS-approved, but, boy, did I feel better for it.
