The Clinic

I've donated sperm in the past, though it's never been quite this... detailed. In the past, I've just gone to a clinic, gotten my cup, shot off a red rocket, handed over my seed, got my money, and left. This time it was different. For starters, I didn't go them, but rather they came to me, stating that they were seeking my involvement due to my 'genetic make-up.' The way they said it, I assumed it was because of my particular species, but whatever. I wasn't working at the time, despite pressure from my extremely obstinate father to get a job. I'd worked a few odd jobs since graduating high school, but they were all minimum wage, no experience necessary kinda jobs: fast food, department store, those kind of things. I hated every second I worked at one of those places and decided my time was worth more than what they were paying me to put up with. But my old man insisted that if I wasn't gonna go to college then I should start working and build up experience to advance so that I'm not making minimum wage my entire life.

So there I was, sitting in a plastic chair in a small waiting room with no windows, no TV, and two doors with one that lead to the entrance and another that lead to the "donation lab," as it's known. When they first contacted me, they told me that they were interested in collecting sperm for private investors and if I might be interested. I wasn't sure what that meant and when I asked them to elaborate, they told me that they'd explain more if I agreed and only when I go in to donate. I was hesitant at first, but when I asked what they were paying, they told me that for my breed (not sure why they'd phrase it like that), they'd be offering me $500 for ten hours of work with a possible commission. Three questions popped into my mind at that moment. First, $500 for ten hours of work, are you fucking kidding me? Second, How in the hell does donating sperm take ten hours? Do they expect me to jerk it for that long? Lastly,Possible commission? Does that mean they're going to auction off my cum?

My intrigue was aroused, but so was my ignorance on the matter as no matter how much I implored, they left me in the dark as to what their particular process entailed. I had to think it over and in the end, I gave in and decided that if all they wanted from me was my foxy-juices, for $500, how the hell could I refuse? There was a major stipulation though. I was not allowed to have sex or masturbate for an entire week. It was doable, but after a couple of days I get some pretty dirty thoughts in my head and my paws start to wander. I had to avoid any and all porn and spent most of the week reading science papers that I could barely understand just to keep myself distracted. It worked, but as I sat there in that plain-ass room with nothing to do I found my mind slinking back to thoughts of buff stallions in jock-straps with a thick bulge underneath.

The images clouding my mind caused my sheath to begin filling out and my underwear to tighten. Before leading me into this room, they asked me to remove my clothes leaving me in nothing but my tighty-whities, which was a bit humiliating for me since I haven't been this exposed in public in a while. I tried to think of it as being at a swimming pool, but it did little to alleviate my embarrassment. I got some interesting comments about my fur patterns, which highlighted aspects of the raccoon side of my genes. Most of my fur kept the usual fox color patterns, red fur, black socks, creamy white belly that covered my chin. I did, however, have a black mask over my eyes and a black-striped tail indicative of typical raccoon patterns. As a child, I was teased for it, but as an adult people seem to really like it.

After signing a non-disclosure agreement, I was given the details about what I would be doing. I wouldn't be masturbating like you'd typically expect from a sperm collection agency. They said that I'd be strapped to a male-milking machine with a clamp around my penis that would stimulate me to orgasm and collect my seed. They told me that they'd also be stimulating my prostate to enhance the process. I could choose either an electro-stimulator or, and I couldn't help but blush when they asked me this, I could choose a particular dildo. I grew a smile so wide, I felt like an immature child. Even more surprising was that they actually had different species' cocks. I was rather embarrassed to choose one, but they seemed serious about it, so feeling adventurous and kinky I told them I'd like the horse dildo. "Good choice," they said to me, making me blush crimson red under my milk-colored fur. My sexuality also came up, but since I was already asking to having a horse dildo shoved up my ass, I figured it was obvious.

I'd be strapped down, so they'd have to feed me through a tube. They'd also be supplying pheromone-rich musk through a tube to drive my sexual arousal. It all seemed like high-tech BDSM as opposed to a medical procedure. The one thing that made me uncomfortable though was the idea of having something shoved up my urethra. They said they had to shove one tube into my bladder to collect urine so that I don't pee during the procedure and contaminate the samples. Two more tubes would line the vas deferens leading to my testicles to supply chemicals that would accelerate proliferation of my sperm cells as well as production of seminal fluid. It was all a lot to take in and it was making me uncomfortable to think about all of this happening to me in public, in front of total strangers, and for ten hours. But, again, for $500 I could put my shame aside for one day. The one detail they still refused to provide was why they needed so much cum from one person. They said revealing that could be construed as a violation of consumer privacy. I shrugged and just went along with it, even if it didn't make any sense to me.

The door to the donation lab opened up, finally, and in walked a tall, male raccoon in a lab coat. "Mr. Rodney?" he asked.

I nodded. "Yep," spoken in an 'as a matter of fact' tone.

"Hello. My name's Dr. Corbin." He extended a paw to which I took it in my own and we shook paws. "You ready to get started?" he asked with a friendly smile on his face.

"As ready as I'll ever be," I said standing up, the fact that I was already getting excited evident through my underwear. He didn't seem to take notice of it.

"Alright then. Follow me, if you would." He gestured to me and I followed him through the door and into a small hallway. There were four doors, two on either side of the hallway, and a fifth straight ahead.

"I like your mask," he said to me. Figures he would. "Is that on your mother's side or your father's?"

"My mother's actually."

He stopped at the second door on the right. "I bet you get a lot of questions and comments about it."

"Not as much as when I was a child."

He pulled out an ID card and held it up over an electronic reader, getting a ding that unlocked the door. "Yeah, when it comes to kids, if there's something different, they have to mock it."

He opened the door and slowly I walked in, getting my first glimpse of the chair I'd be strapped to. It looked like an operation table at a gynecologist's office, except it was upright and a little laid back. Also, it was a chair. There was no seat, but there were leg stirrups and feet rests for my hindpaws. There were cushions for my back that were curved to align better as well as a head rest and arm rests. The chair hovered over a small, mechanical, circular contraption with some kind of protrusion poking upward. Considering where it was pointed, I didn't really have to guess what that was for. There was a clear tube hanging from a box in the ceiling situated about where a person's muzzle would be. Off to the side there was a large, mechanical, rectangular box with numerous glass vials. Connected to it via three small tubes encircled by a single large tube was a large, curved, phallic-shaped metal casing. I knew full well where that was going.

To the left was a desk with two computers on it, a desktop with wires plugging into the box under the chair, the box in the ceiling, and the box with the collection tubes. The other was a laptop, no doubt for the doctor to do some work while I'm being manhandled... or machine-handled. I was starting to feel uncomfortable standing here, seeing the mechanistic platform of sexual encroachment that I would be submitting to. My erection began to fade as my discomfort levels rose and the clinician shut the door behind us.

"Alright. Go ahead and remove your underwear if you would please."

"Uh, OK," I said with extreme hesitation. I slowly removed my underwear, revealing my nicely sized sheath and shapely rump, my embarrassment levels skyrocketing. I stepped out of them, fully nude in front of the fully dressed raccoon and at least 4 cameras that were pointed right at me.

"You can put them on the table right there," he said pointing next to me. I picked up my white briefs and laid them out on a metal table and turned towards the coon. "Alright, come on over here and I'll get you set up."

The doctor lowered the chair a little to make it easier for me to climb in. I have to admit, my reluctance to continue with the whole procedure at that moment was through the roof. I was naked, he was fully clothed, and he was about to strap me into a machine that was going to be pumping my cock mercilessly while pounding my ass like a dominant partner. I almost wanted to refuse, thank him for his time, apologize for wasting his, and run out of there with what little dignity I had left. But, I did already sign the papers and it's not like anyone was forcing me to do this. I took a few deep breaths to calm myself before finally, though cautiously, stepping forward.

The doctor chuckled lightly. "Don't worry. It's not as rough as you might think. All of our clients say it's quite enjoyable after you get used to it."

I smiled weakly as I stepped up to the chair. "I'm sorry. I'm just... a little embarrassed about all this."

"It's OK to be nervous. Everyone is, but I assure you I'm a professional and if you need to stop at any time, just let me know. OK?"

"OK," I said, feeling a bit more reassured.

"Would you like some help climbing up?"

"No, I... uh... I think I got it." I knew he'd be touching me soon enough, but I still felt uncomfortable about the situation. "Is... uh... is this all part of my ten hours?"

"No. The timer doesn't start until we start up the apparatus." In other words, I wasn't getting paid at this point.

I grabbed the arm rests to hold myself steady as I lifted one leg up onto a stirrup and then rested that leg as I brought the other one up onto the other stirrup. I placed both arms on the arm rests, leaving my legs spread, my sheath and balls exposed and prominently displayed, and my ass hanging out in the open. It took a bit of effort not to bring my tail up and cover my privates. Black cushions covered every part of the chair, making the seat fairly comfortable, which if I was gonna be here for ten hours I'd expect it to be. The doctor then began lacing the straps on the chair around my wrists, ankles, neck, chest, waist, and finally securing my tail back so that it couldn't get in the way.

I gulped reflexively, my nerves preventing me from getting hard, making my shame grow even more. "I'm sorry doc. I, uh... I don't know if I'm gonna be able to get... it... um..."

"Erect?" he finished for me and I nodded. He smiled. "Don't worry about it. That's not gonna be a problem."

He seemed pretty confident, but I felt no desire to unsheath my member at the moment. As I sat there, strapped in and secured and at the mercy of whom I hoped was an honorable doctor and not some perverted sex slaver who was here to milk me for his own depraved desires, the doctor moved to my side. My cock twitched out of nervous habit as he grabbed the long, clear tube hanging from the box in the ceiling and pulled it in front of my face. As he did, I noticed there were actually two tubes in one. The main tube and then another internal tube with a small hose just inside the nozzle, which was shaped to fit around a canid's muzzle.

"Now, this is going to supply you with a large supply of strong pheromones to maintain sexual arousal. The tube on the inside will supply you with food and it's all in liquid form so try to keep your muzzle closed when you feel it trickle into your mouth. OK?" I nodded. "Alright, now open your muzzle."

I did, my heart beating fast as he secured the mask around my muzzle, sticking the end of the feeding tube into my maw. "Now bite down." I did as instructed. The tube was a little wide, making it hard to close my lips around it. The doctor then pushed a button on the underside of the nozzle, causing the ends to expand around my muzzle, locking it in and preventing loss of any pheromones. My breathing increased and I could tell I looked panicked. The doctor secured some straps on the nozzle to my head, locking it in place. He stepped over to the desk and got on the computer.

"Now don't fight it. Just breathe steady in through your nose."

He pressed a couple of buttons and shortly after I heard the woosh of air entering the nozzle and soon after that my nose was blasted with a wave of some hot, smelly gas. I paused a moment nervously before breathing it in, letting the gaseous mixture overwhelm my olfactory senses and once I did, once I got my first whiff of that odoriferous fragrance, my entire body tensed up. It was like I was smelling the largest and longest-lasting orgy of hot, dirty, sweaty bodies I've ever encountered. It was like my nose was pressed up against the crotch of a guy whose had his dick in every other guy's ass and was coming around for round two. And they weren't lying, it was strong. I felt tingly all over and my arousal went from 0 to 1000 in no time. My cock popped out of its hiding place and grew stiff in record time.

I took another whiff, forced to breathe in the rancid, musky stench, driving me to a sexual state I could only describe as male heat. I continued to breathe it in, letting the pheromones take over my body and enslave my mind to sexual excitement. I began to rustle around in the chair, my body naturally reacting to the erotic sensuality I was experiencing. I could probably get off from the smell alone.

"See, not a problem," I heard the doctor say, though somewhat hazily in my consciously-clouded state. I saw him standing next to me, paws covered in latex gloves. Now came the part that I feared the most, the part where he starts feeling me up, though to be honest at that particular moment I didn't really care. "You OK?"

I could barely think, wanting nothing more than to just explode in a stream of hot, fox/coon spunk. It took some effort to actually focus on the doctor and his question, but I managed to look at him and weakly nod my head. He smiled back.

"Good." He reached down and grabbed something, but I didn't see what it was. "Now this next part is usually the most uncomfortable, so I need you to just bear with me, OK?" I barely heard him and barely cared. I just wanted him to get it over with so I could cum already.

He didn't wait for me to answer. He reached between my legs and took hold of my aching member, the touch garnering a shudder from me as my member was overly sensitive from the hormones invading my nostrils and the fact that it hasn't been touched in a week. He then began to massage the base of my penis, the point where my knot was located. When it came to genitalia, my canid genes won out and my cock is, for the most part, fox-shaped. He massaged it enough until my knot formed, but the treatment to my penis was bringing me closer to orgasm and there was nothing attached to collect my sample if I cum. I was worried I might waste the first sample and he mirrored that concern.

"I just hope I can get this on in time. You look like you're about ready to explode."

And he was right. I suddenly felt something cold and metallic attached to my knot, squeezing it slightly, but not uncomfortably so. It did, however, edge me closer to my climax. I couldn't see it at the time, but there was a cable attached to the underside of the clamp around my knot and when the doctor got both sides of the clamp attached, something became activated. I heard the doctor sigh with relief.

"Good. We've secured the first sample."

I wasn't sure what he meant because I still felt my climax building up, but there was nothing I could do anyway. The musky scent was driving me insane with lust. Shortly after my knot was clamped, I felt something hard and slick being shoved into my urethra. I cringed slightly as I realized a small sound was being inserted into my dick, but it only felt a little uncomfortable. I was expecting something a bit bigger. He then placed something small on the end of the sound with a small metal claw inserted just passed the urethral opening.

After a moment, I heard the doc say, "Alright, now. Deep breath." Why would he say that to me? What happened next I was not expecting, nor was I sure how to deal with it.

The doctor fumbled with the device on my cock head and I felt the sound in my cock expand and open up my urethra wide. I felt a surge of burning pain in my cock and I clenched up at the sensation. I fought my bonds, but they didn't give way and then I tried to protest, but with the gas tube around my muzzle I couldn't say anything.

"Just relax. Breathe in the pheromones. The pain will dissipate. Just bear with it for a moment and it'll pass."

I tried to protest, but the doctor continued with the treatment, forcing me to bear the painful fire in my dick. He then began to thread two small attached tubes through my urethra. I didn't feel them going through my penis, naturally, but I did feel them once they moved past the boundary of the sound. I felt this odd pressurized sensation in my groin as the tubes were shoved through my urethra into my prostate and I'd be lying if I said it didn't feel kind of arousing. One of the tubes, transparent and blue, was shoved into my bladder and from what I understand now it created a plug to prevent leakage of urine from the bladder into the urethra. This way, all the urine would be collected through that tube and into a separate waste container. In other words, a catheter.

The second tube, transparent and purple, was manipulated in my prostate and two tubes were revealed with one going into either of my vas deferens ducts. The feeling was weird, as it's pretty much impossible to describe as I've never felt anything like it before. My heart started palpitating as the sensation was moving around my bladder and down towards my testicles. The building pressure towards my sensitive nuts sent fear throughout me and I panicked, worried that pressure would reach my scrotum. Fortunately, the tubes stopped just short of my jewels and I felt a sense of relief.

It was then that I noticed I could no longer flex my cock and that's why I wasn't climaxing. I found out later that the clamp on my knot was sending electrical signals to prevent the involuntary (or voluntary) smooth muscle contractions that would allow me to ejaculate. In this sense, they would be controlling when and if I cum, which brought a newfound sense of fear to me. I had also noticed, though, that the doctor wasn't lying about one thing. The pain in my cock had dissipated so the fiery pain in my dick had faded and all I felt was an incredible pressure opening me up, though it wasn't entirely unpleasing.

At that point, my urethra was wide open and I had two noticeable tubes pointing out of it. The doctor grabbed the casing connected to the collection box I noticed early and brought it over. He took off the large, metal case and covered my dick with it. It was three circular plates with large holes in the middle connected by metal tubes and right down the middle was a black membrane. He connected it to the clamp on my knot and readjusted it so that it covered all of my member save for the head. He then pressed something so that the membrane engulfed my dick, squeezing it tightly. Normally, that wouldn't be so bad, but with the sound in my urethra, it just increased the pressure, causing a high degree of pain. That would soon fade to be replaced by erotic pleasure.

He then covered my head with some clear, slick, transparent membrane with a small protrusion sticking out the top, sort of like a condom, that felt slimy to the touch. He pushed the two tubes through a hole in the membrane and attached it to my glans where it created a suction around my cock tip. I now had three tubes pointing up from my penis: one for urine, one to inject chemicals into my balls, and one to collect my ejaculate. If I weren't so nervous or apprehensive, I'm sure I'd find this incredibly erotic. He squeezed all three tube tips into the proper color-coded tubes which connected to the collection machine and then covered my glans with a metal case, fully encapsulating my foxhood. He turned to the collection machine and flipped a switch, causing it to whir with life.

At this point, my mind was cloudy with lust from the pheromones assaulting my senses and I was barely aware of what was happening around me. "I know it's painful, but we're almost done here. Just a little bit longer and you'll get the release you need." I opened my eyes slightly to look at the doctor, trying to plead with him to give me release now, but he was already moving to the last step. I struggled more with my bonds, shuffled around in the chair, but it did no good.

The doctor messed around with the chair, bringing it down a little, bringing it up a little, tilting it one way and then the other. Turns out he was trying to align my tailhole with the protrusion on the circular machine under the chair. I was right. That's for the dildo that's gonna be pounding my ass. He inserted something slick that would be loosening me up and lubricating my anus. It wasn't nearly as thick as a horse dong, but I still felt it. He did something with the machine, causing it to insert slowly into my rectum, spreading my sphincter open and pushing in a few inches at first, then a few more, and finally a few more. I think it was a good 10 inches inside of me as he let the machine slowly pump a few times, coating my anal walls with a very slick lubricant and making my backside opening used to being stretched. He then inflated the shapeless dildo a bit wider, making my butthole tingle with sensitivity and my accumulated lust inch ever closer to orgasm.

After a few more thrusts, the doctor removed the small phallic object, leaving my butt feeling empty and cold. I couldn't see him replacing it with a horse dildo, but I would soon feel it. "Alright, this is it. After I've got this positioned, we'll get started immediately. At that point, the timer will start." I breathed in more of the pheromones, anxious beyond words to just get on with it. Every second the doctor teased me felt like minutes in my lust-deluded mind. The doctor continued messing with the chair and the pumping machine, making sure it was aligned precisely to avoid injury. I felt the head of the horse cock pressing against my rump and it was a bit bigger than I expected.

"OK, deep breath," was all I heard before I felt an incredible pressure against my back door. I struggled with groans around the feeding tube and gas mask as my anal sphincter was violently shoved open to accommodate the massive size of the cock head. But the doctor stopped there, leaving the flared up head just passed my tight ring without inserting any of the shaft.

"Alright, now we can get started." The doctor stood, removed his gloves, and walked over to the computer, leaving me bound to a chair, forced to smell the musk of countless people, asshole stretched and tingling with pleasure, urethra stretched to unnatural proportions with tubes invading my internal sex organs, and a slippery, fleshy object squeezing my cock. I don't think I've ever had to cum so bad in my life.

The doctor seemed to take his sweet time at the computer, setting up functions and punching in commands. It was torture to me, watching him work and wondering when, if he was ever, going to let me finally cum. "Alright, here we go." I suddenly felt the dildo at my back entrance push forward, slowly spreading my intestinal walls aside to accommodate the huge phallus, invading my rectum and occupying the depths of my bowels. I took it all, inch after inch, the medial ring moving past my anal ring and shoving deeper still. It was designed to exude a very slick lubricant whenever it starts to dry up so that it always stay slippery and prevents friction. As it filled me up, my prostate was overcome with euphoric sensations and I could tell I'd hit my peak, but I was still unable to orgasm thanks to the clamp on my knot. It was getting closer to the base and my intestines were filling up, my ass being spread wider than it ever had been before. As it reached the last few inches, I felt the cock head pressing up against my colon and a sharp pain in my sphincter. Then suddenly, it stopped. It hadn't hilted, but it was close. My body was tense, every muscle strained and ready to convulse as the dam holding back a cascade of mammalian spunk was ready to burst. But still, I was denied. I wanted to beg, but my mouth was occupied.

I stayed frozen in that moment, ass splitting and on the verge of climax, for some time it seemed. And then I felt the dildo retract, a feeling of relief and sadness overcoming me as the sensation of being filled was replaced with emptiness. The dildo receded to the point where only the head was still inside me and then stopped, before being shoved back in. I moaned through the gag and mask as every inch entered me again to the point it was before and was then removed again. The thrusts became constant, starting off slow and then picking up speed until it became rhythmic, but it still picked up in speed. It was moving relatively quickly before it finally settled on a constant pace, brushing up against my prostate with alacrity and sending shivers of painful pleasure throughout my crotch, making me almost cry with sexual desperation.

"Alright, looks like you're ready to go. Just bear with it a moment. It might take a minute before I can release the smooth muscle inhibitor."

What does he mean by that? I wondered. I was ready to explode now. Just release it and take my seed. Instead, I heard an electronic whir and in a second I felt the most intense form of stimulation on my cock I'd ever felt in my life. My eyes bulged, my body stiffened and I tried futilely to arch my back. It was like my cock was covered with lube, shoved into the tightest asshole imaginable, while being stroked along the base at breakneck speed and licked along the head by the slimiest of tongues. My groin felt lightweight and the pressure intensified and I could feel my cock fighting to release my man-milk, but the doctor, for some reason, kept me in this state. I struggled and fought against my bonds, but nothing came of it. The dildo continued to assault my ass while the case on my cock continued to stimulate me beyond the point of orgasm.

"I know it's hard, but we're almost there."

Why is he doing this to me? Why won't he let me cum? I thought this is what I was here for? This is fucking torture! These questions and thoughts went through my head as I continued to struggle to free myself, free my cock from this inhumane treatment. I needed release and there was no reason to deny me it. The sensation grew more and more intense and I began to cry as I could do nothing to resolve it. I felt like my insecurities were right. This guy really was just a sex slaver.

"Aaaand... ... ... there."

The doc hit a button on the keyboard and just like that I shut my eyes as my body convulsed. The dildo embedded itself deep into my rectum as far as it would go as the inhibitor on the clamp was finally ( FUCKING FINALLY!!! ) released. My groin felt like a flash flood for a moment before my cock erupted like a broken fire hydrant and sperm spewed out and was sucked up by the tube and collected into a large vial. I flexed my cock as well as I could inside the casing as I groaned and moaned and shuddered with sexual bliss while a steady stream of semen was milked out of me. The musk helped drive my orgasm to enhance the experience as ounce after ounce of jizz left me. I felt like I was pissing cum for a minute and a half (though it was actually closer to two minutes) before I became empty. I continued to shudder and trilled under the mask as my cock was still being stimulated slightly, trying to milk ever last drop of my seed out of me.

Once I was empty, all sense of stimulation ended and I was left with the feeling of my cock being squeezed tight with my urethra opened wide. The dildo in my ass retracted, pulling all the way out but leaving the head still embedded. I didn't realize it at the time, but I was purring, something I did out of habit since I was a child. I was lost in euphoria from experiencing the most pronounced, most explosive, and outright best orgasm I've ever experienced in my life.

"So, I'm going to inject you with chemicals now to help replenish your supply of sperm as well as other seminal fluids." The doctor brought me out of my reverie when he spoke. "It's going to feel a bit cold at first, but it'll warm up after a moment."

I gave a very weak nod, though I wasn't sure if he noticed it. I was breathing heavily from the afterglow, my belly moving up and down quickly. After a moment, it was as the doc said. I suddenly felt a cold sensation running from the base of my cock up through my crotch and down again descending into my balls. It was a lot colder than I thought it'd be, but it wasn't unpleasant. In fact, it was actually rather sensual. And then, like he said, there was a warmth spreading in the same fashion, but it wasn't exactly the way he described it. I felt the warmth spreading, but the cold never actually went away. It was if the heat and the cold accentuated each other 'cause I felt them both at the same time. It was so exhilarating and I was so glad I decided to do this.

I then felt a bit of discomfort in my testicles which was soon replaced with a tingling sensation that I didn't really mind. It would remain there until my next sample collection. The warm and cold sensation slowly dissipated leaving me with just the invasive sensations from the horse dildo and penis sound as well as the mind-numbing effects of the pheromone-rich musk circulating in front of my sensitive nose.

The doc stood up and walked over to me, speaking as he did. "OK, you're gonna get a ten minute break and then we'll begin your next session." I didn't respond. I just lay there basking, exhausted and panting. He patted me on the arm. "It seems you really were aching for release. Your first sample was quite prolific."

He pointed at the collection chamber and I noticed one of the collection vials had my semen in it and it was about a third of the way full. It could've contained maybe a cup and half or two cups worth of liquid and I managed to fill up a third of it in one go. I didn't even know how I was capable of filling it up so much.

"Oh, I meant to ask this beforehand. The nurse is supposed to tell you about this, but sometimes they forget. Did she tell you about why we hold off from letting you ejaculate?" I turned to look at him with a confused and fatigued look. "That it helps to build up the amount of product as well as helps to purge your system of semen. That and most of our clients say it makes the experience much more pleasurable. Did she tell you that?"

I was laughing internally. No, she didn't tell me and I hadn't realized that's why they do it. It didn't matter at that point. I think my insecurities were the only thing keeping me from enjoying the experience and now that I know it was intentional and reasonable, if this is how he intends to conduct this procedure, I'm going to enjoy it a lot more. I simply shook my head lazily to answer his question.

"Oh my God! I am so sorry. I should've said something earlier. I didn't mean for it to be so hard for you. I mean- OK, bad choice of words." I chuckled into the mask. I knew what he meant, but he seemed to think I took it as a double entendre. He laughed a little in response. "Well, as long as you enjoyed yourself. Now, I know you're tired, but since you're probably a bit more level-headed, I was wondering if you wanted some visual aids to help with your stimulation."

I wondered what he meant by that as the dildo in my ass was causing a good deal of pleasure, as was the tightening grip of the membrane on my cock and the ironically enjoyable feeling of having my urethra opened by the penis sound. That and the heat-inducing pheromones I was breathing in. What else could help stimulate my sexual appetite? It was then that I noticed the large monitor hanging over the doctor's desk.

"Most of my patients enjoy some good pornographic imagery to help get them aroused and drive them quickly to climax. Would you like me to turn it on?" I gave an enthusiastic nod. "Alright." He began to walk away and went back towards the computer.

After a moment, I saw the monitor come on and I was treated to a series of pictures of some hot, sexy studs. Various species including bulls, wolves, horses, lions, zebras, cougars, and rhinos. I soon felt something sweet, meaty, and sticky flow onto my tongue and I realized I was being fed. It was kinda tasty, but nothing special, just a liquid nutritional supplement. A small surge exited the feeding tube directly onto my tongue falling straight down into my throat and I guzzled it down eagerly. There wasn't much and I figured it was probably gonna be like this all day. Give me a little bit after each session to re-energize me.

I heard a beep on the computer and soon after the doctor said, "Alright, we're ready to start up again." That was fast. That didn't feel like ten minutes at all. But nevertheless, I was happy for another round. I didn't feel tired or sore and the tingling in my testicles was all but gone. "Are you ready, Mr. Rodney?" I nodded my head eagerly. I was absolutely ready to donate again.

Soon after, the images on the screen turned to video porn of a fox tied up in bed while getting pounded by a large horse and at the same time eating out the asshole of a bull. It was so hot I felt my next orgasm building already. I suddenly felt the dildo in my rectum begin it's rhythmic thrusting again, building up quickly in pace back to what it was the first time I came. My mechanical cock cage whirred to life and I was greeted with more electrical stimulating that, along with my anal abuse, the musky air, and the porn I was watching, brought me to climax in only a couple short minutes. And just like before, the knot clamp prevented me from releasing too soon, letting my orgasm build to a wild state before the doctor would grant me mercy. This time, however, I was ready for it and anxious to enjoy every second of edging and teasing this sadistic raccoon would be submitting me to. As it sat there, struggling uncontrollably with every amorous body part stimulated to its maximum level, I thought to myself, This is the best damn day of my life!

One other thought crossed my mind, a single doubt that refused to leave: How the hell am I gonna keep this up for ten whole hours?

****** Epilogue ******

It wasn't easy, but I did it. I was teased/edged for a minute as my orgasm built to overwhelming levels before I was able to eject my fox/raccoon essence into one of many glass vials to be stored for later use. After that, I would rest for ten minutes while my testes were stimulated to grow more little soldiers and then the process would repeat. I never really noticed the catheter, but I guess that's a good thing, as I find having to take a piss while getting off a bit distracting. My guess is that it would continuously remove any urine in my bladder so that it was consistently empty. For a while, I handled it well enough. I got tired after each session, but by the time we started the next one I was well energized and eager to go. But as the day wore on, I found myself exhausted and unable to really enjoy the experience as much as the start of the procedure. A couple dozen orgasms will do that to you. By the end, I was so exhausted that I could barely move on my own. Everything was removed, my ass and cock felt so empty without something shoved inside of them and the air just smelled wrong without the scent of sweaty, sex-riddled bodies.

I was taken to a room where I could clean up and rest before I got dressed, got paid, and left. I never told my mom or dad where I was because, for one, it was the last thing I wanted to explain, and two, I did sign a confidentiality agreement. Fortunately, they didn't seem to mind that I was gone for over twelve hours that day a week ago.

I was pretty sexed out for days after that, but I couldn't stop thinking about what an enjoyable experience it was. I was kind of wanting to get back and do it again, but I wasn't sure if they'd accept, or even need, me again. About five days after the procedure, they contacted me to tell me my commission check was in and also, much to my surprise, that they really wanted me to come back, even willing to increase my pay. I once again asked them why they were so desperate to get me back because it really was suspect, but once again they refused to explain. Finally, I told them that I refused to come back, insisting that I would not allow them to take anymore of more seed until they explained to me what they were using it for. There was no way that many people were impregnating themselves with my specimen and I even got it in my head that they might be using it as research to make clones.

Finally, they relented, telling me only under the agreement that if I told anyone else it would be grounds for a lawsuit. I agreed and it turns out the reason was both less disturbing and more disturbing than I thought. Apparently, there were some wealthy people who had exotic tastes in... ... ... beverages. It took me a moment to process that, but it turns out that people were drinking my semen. That's why they wanted me back, it was in high demand due to the rarity of my species. Not only that, I was told some people liked it without the pulp and some wanted only the pulp. It took me a second, but I realized they were purifying my sample and separating the sperm from the rest of my semen. It was considered a delicacy. I thought about it and the idea was actually kind of gross to me... ... ... and kind of hot.

Now that I knew, I asked how long they'd need me for and they told me indefinitely. I was excited as it meant an actual job and I'd only have to work once a week. The downside was two-fold. First, I'd never be able to jerk off outside of the clinic. And second, I'd have to tell my mom and dad something, anything about what I'd be doing and I felt it most prudent to come clean and tell them the truth. This meant telling them I would be selling my cum for money. Fortunately, due to a confidentiality agreement, I was prohibited from going into details, so I didn't have to explain very much.

So here I stand, outside my mom and dad's room with my parents inside. My heart is palpitating and my stomach fluttering with my nerves on edge about telling my parents such a personal and embarrassing thing. Oh well. I knock on the door, wanting to just get this over with.
