A Doctor's Appointment

Originally I submitted this story to the old ManMods website, which is now gone, and I thought someone here might like it. If you have comments I'd be happy to take them.

Contains extensive urethral sounding, precum & piss, extreme anal and prolapse.

-----------------------------------------------------------------------

Bjorn was panting lightly under the lightweight jacket and the backpack, having almost missed the bus going toward the city center. He had made an early afternoon appointment with a new specialist doctor, and missing the bus would mean being at least half an hour late. Bjorn never liked being late, and for this occasion specifically he wanted to be perfectly on time. At 20, after having moved to a large City to start his university studies in chemistry, he was quite excited about the idea of finally being able to consult a physician other than the GP his mum had brought him to since he was a child. The aging small-town doctor knew him too well, and at the same time knew very little.

Bjorn's "issues" (that is what his GP called them) had started when he was barely in his puberty. One day he had woken up at the age of 15 with a hard-on - which he was used to - but with his underwear utterly wet. With a rush of embarrassment, he had uncovered himself and noticed that, unlike he feared, he had not peed himself during the night. The underwear was sticky with a clear fluid that was leaking out in small but continuous drops from his penis. That morning, he quickly took off his clothes and took a shower, stuffing the dirty boxers together with t-shirts in the laundry bin, hoping his mum would not notice. And hoping it would not happen again.

It did happen again. Every morning, from that day on, he would wake up with underwear soiled in sticky pre-cum. He googled about it on his phone, late in the evenings, trying to understand if this was normal or, as he rather feared, freakish. And eventually others - and his mum - did notice, when the pre-cum started to wet his underwear at school or while doing sports in the afternoons. He tried hard to hide it, as he thought he should be embarrassed by it. The gray-haired GP told him - after a short and embarrassing body check-up - that his "issues" were not common, indeed, but there were no clinical sign of disease. He was just made this way, and had to accept it.

"Do you masturbate?" The GP asked, while filling an electronic form on the screen. His mother was waiting in the waiting room, thankfully.

"Sometimes. But I was afraid that the problem could, you know, get worse... maybe?" answered Bjorn looking down at the mint green tiles.

"Nonsense." the doctors had a calculated, reassuring smile "In fact, I suggest you do it more. At least once a day should help you with your 'overflow' condition".

And that was the end of it. The GP told his mum that nothing was wrong with Bjorn and that the issue would resolve itself naturally as puberty went on.

The bus stopped, and Bjorn stepped out into the still warm September air and sun. He walked a few hundred meters in what seemed to be one of the best neighborhoods of the City: all old two-story houses circled in private gardens, on a short hill just behind the old town center. He found the one, and entered the opened metal gate. When he rang the bell, the door opened with a buzz. He let himself into the white entry hall where a coat hanger was, and light but old wooden floors were, too. A tall staircase was in front of him, also of wood. Bjorn took his jacket and backpack off while looking at the chalk white walls of the house. A 50-something man popped out of the door to the immediate right, looking tired but relieved.

"I'll try to do that, yes Doctor, yes." the man said, and looked briefly at Bjorn, then took the heavy dark coat hanging next to his and left in a hurry. Bjorn stood briefly.

"Oh hi, sorry, you must be Bjorn right?" 

A young man, tall but sturdy in his white medical coat and blue shirt with tie, was looking with his face at a slight angle. He had short brown hair and glowing brown eyes in the afternoon sun streaking in from the window above the entrance door. Bjorn could see his pants were tight around the calves, almost too tight, and his arms, too, filled his lab coat. The doctor had a gentle smile on his clean-shaven face, but whether it was rehearsed or honest Bjorn could not tell.

"I-I am, yes." Bjorn smiled too now.

"Ah great, please do come in."

They seated themselves at a wide glass and steel desk, Bjorn to the patient side, in what was a large, fully equipped medical office. There was the bed, the cabinets with various sized bottles, the desk, some other machines and shelves. Two paintings, abstract in nature, and a tall wide window covered by white curtains.

"So what can I help you with Bjorn?" The doctor looked intently at the young man. Bjorn was light skinned compared to the physician in front of him, just as tall but skinnier and with a short stubble of bear on his face. He was wearing a dark hoodie and jeans with worn sneakers.

"So, doctor, I"

"Please call me Nils. Or doc. My mother used to be 'the doctor', and I prefer to be less formal with my patients." Nils smiled, again.

"Okay. So, doc, I have had issues with my penis since puberty and my family doctor never really cared for them much - told me they would go away with the time, basically - but I still have them and I want to know if I am alright or not, you see. So I needed to see a specialist and well, I found your name online." 

"Very well, Bjorn." said Nils, not lifting his gaze from the young patient.

"What are these issues then?"

"I constantly leak pre-cum, even when I am only slightly aroused or at random, during the day or night. My GP told me to masturbate more since I was a boy, and I do, at least twice a day I try, but it does not really solve the problem, you see. And when I cum, I cum a lot, like A LOT." Bjorn was biting his lower lips saying this, as he felt embarrassed.

"I see" the doctor nodded, and got up from the chair.

"I will take a look now and see, okay?"

"Okay, Nils." Bjorn rolled Nils' name a little too gently off his tongue, as he noticed what seemed a thick, fat bulge in between the doctor's thighs. He thought he almost saw the fain print of a large cockhead. He was beginning to get horny, which meant his own penis would start its leaking now.

"Please get fully naked, you can leave the clothes on the chair there." The doctor was putting on sterile gloves in a corner of the room.

Bjorn stripped first to out of his shoes and socks, then out of his jeans, and finally out of his hoodie and t-shirt. For a moment, while folding his clothes, he was left only in his gray boxers.

"I see no leaking now, Bjorn." Nils was looking at Bjorn in a certain way, the young man understood, with a certain desire, he could tell. But Bjorn was not sure, though he did blush slightly.

Instead of answering, Bjorn stripped out of his underwear, finally showing his semi-erect, plumping 7.5 inch penis and thin, blond bush of pubic hair to the doctor. Bjorn was what one could call a "perfect twink", with just a little muscle mass and almost no hair over his body, save for his bush, armpits and his face and head. His balls were rather large, almost as kiwi fruits, closely hanging from the thick base of his dick. The dick was quite thick at the base, then got slightly slimmer and again thickened before reaching a big, fat meatus, which was still covered in foreskin. And of foreskin Bjorn had a lot, so that even know, when the mildly chill air of Nils' office stimulated Bjorn's cock to spring up to a full erection - jutting out at a 60-degree angle from his crotch - his cockhead had a half-centimeter ripple of loose skin hanging from it.

"I'm sorry" said Bjorn looking right, to the bright white curtains, blushing hard.

"No issue at all! I am a urologist, Bjorn, it is rather related to my job, you know?" replied Nils almost in a laugh. His voice was kind and full. Nils finally came close to study Bjorn's penis.

"I will uncover you penis now" and so Nils did, and slowly peeled back the thick, moist foreskin from the boy's dick. Bjorn was getting warm now, a bit from the excitement of that tall, hunky doctor touching him, and a bit from the warm light flooding the room.

"Oh I see... Bjorn, what did you do here?" 

"Well I... I had to stop the pre-cum somehow."

"Since have you been using urethral plugs, then?"

Bjorn looked down at the doctor looking up at him with bright chestnut eyes. There were the tiniest drops of sweat on Nils' forehead now, he noticed.

"Since I was 15?" he hesitated.

Bjorn's uncovered cockhead was a bright purple and shiny in the light. A thick, large yellow nub was coming out of the boy's urethra and by touching the penis, Nils could tell that there was a large object stuck deep into the young erect cock. It was made of medium-hardness silicone.

"Okay okay... and also, I notice you have no frenulum."

"I was born like that, my doctor said." Bjorn angled his lips on a side, uncertain.

"I guess masturbation must be pretty easy for you then!" Nils said to joke, and t his patient smiled at him then.

"Good, no problem there. I will take your plug off now though."

With his right hand, Nils grabbed the silicone nub, which was squared-off, and with the other he grabbed the base of the cock, behind the fat balls of the young man. He pulled slowly but firmly, and with a silent pop a thick bead pushed out of Bjorn's meatus. A clear drip of pre-cum then started dripping off the penis tip.

"Uhh" Bjorn sighed. But Nils was fixated on the boy's penis now. He pulled more and another, larger bead popped out, again with a thick drop of pre-cum and a moan from Bjorn. Then, a series of beads of decreasing size was pushed out of that hard teenage cockhead, with a torrent of thick, sticky liquid jetting out and onto the floor, pooling as it dripped. After longs seconds - when Bjorn almost pissed the seminal fluid - the pre-cum was white-streaked and flowed slowly, discharging in drops hanging from long threads. The pool on the floor, close to Nils' knees, was growing steadily.

"Wow Bjorn, that is A LOT of pre!" finally spoke the doctor, getting up.

"I am sorry for the floor, doc... but you see, I need that plug to go about the day." 

"The floor is not a problem at all, easy to wash. But you seem to have quite a strong case of hypespermia."

"I suppose so, yeah."

"Right. Well, nowadays teenagers Google all things, I know." said Nils in a light voice "Even I do that. But your doctor should have known better than just to say 'masturbate more'!" The man laughed now, and Bjorn smiled with him, still looking at the doctor's big chest, large arms and thick, thick groin.

"How long do you keep the plug in?" The yellow silicone plug now rested on the tissue covering of the medical bed.

"A few hours, but then I need to take it off in a bathroom and... well... piss the pre-cum out. Then I just clean it and push it in again. It is the only safe way to have lectures, you see."

Nils looked first at Bjorn, then at the silicone urethral plug gleaning wet. 

"This must be at least 14mm in diameter, that's pretty large. Was your urethra always this wide when you started or?"

"No, I started with smaller plugs I made myself, around 9mm wide. But the more I grew and the more I used them, the larger they had to be. This one I ordered online just a month ago, and I think its already getting too small."

"Yes I see, that can happen."

Bjorn had his arms across his chest, his heart pounding now: his penis was sill pointing upwards and rick hard, with a constant drip of pre-cum that was starting to wet the underside of his cock, streaming down to his tight, lightly hairy young ballsack.

"We probably need to upgrade your plug." Nils said nonchalantly, crossing his own arms on his thick chest. His arms bulged and his shirt strained. Bjorn could not stop looking and was not openly daydreaming about that stud of a doctor talking to him about his leaky cock.

"Oh, you know much about this?"

"Of course!" Nils replied, merrily "I know very well what you are going through... personally." And winked. Bjorn blushed once more, but met the physician's gaze. He could not stop looking at him.

"You do?... Could I..." and Bjorns speech was failing him here "could you..."

"Show you? Well, if that is fine for you, I have no issue with that." finished Nils, while the boy nodded affirmatively. "I am your doctor, all things considered. And I am happy to take off some clothing: the afternoon is always hot in this room."

This said, Nils turned around towards the medical bed and folded his lab coat, placing it next to Bjorn's plug, which had made a noticeable spot on the protective paper. As Nils stripped, his patient was left in silent awe of the man in front of him. The doctor's shirt came off first, revealing a muscled chest with big, hairy pecs. Nils did not have a defined 6-pack, but Bjorn could see the abdominal muscles flash under the beautiful olive skin, fuzzy with body hair. He pushed his leather shoes aside, and took off striped long songs, showing strong large feet. Then his tight sand-coloured pants came off, and Nils' huge calves were in full display: thick and toned, so hard one could break a walnut between them. 

Bjorn now could see that Nils was wearing only small white slips underneath, and they were bulging obscenely now. The doctors' cock must have been half-hard, the boy assumed, for it strained the slips in a monstrous way. He could see very clearly now the print of a huge cockhead, almost double the size of his own. The cock shaft was the same width of the head, and it was massive. The shaft rested on what must have been two fat lemon-sized balls, Bjorn could make out, as some of the doctor's ball sack was showing from the strip sides. And Bjorn noticed that the fabric was not wet.

"Let me take these off, too"

As the slips came off, the doctor's monster cock sprung up to a 45-degree angle from his toned belly, and a heavy, pendulous ball sack hung down at the root of it. Nils was circumcised, but not tightly, so that a wrinkly rim of skin was at the attachment of the meatus. The cock was almost straight, with a slight upward curve and two huge veins running the length of the shaft.

But the most amazing feature of that cock was a large round bead that stuck out of the doctor's peehole, black and shiny. Bjorn knew at once that that was doc's own urethral stopper.

"Wow, doc, that's a huge cock" blurted Bjorn without noticing. He immediately closed his gaping mouth shut.

"Thanks Bjorn, yours is a pretty big, too." smiled Nils, without flinching.

"I am sorry I said that, but... I really like monster cocks, doc."

And the doctor smiled again.

"I bet you do... Mine is a fair 11 inches of meat, and 6 inches in circumference. Now, let me show you..."

Nils then walked to a cabinet behind him, took out a large plastic basin and put it on the floor, under his cock and between him and Bjorn. Then he took hold with his right thumb and index of the black plugs bead. He began pulling carefully, and quickly another large, slick bead popped out of cockhead. Nils made no sound at this, but continued. Then two other larger beads came out. No sign of pre-cum leaking still. Now a monstrously thick, silicone rod was slowly coming out of Nil's gargantuan cock, his meaty peehole lips pushed out and plump. The black rod seemed endless, when, finally, a last bulbous, drop-shaped bead pop out of the monster peehole. The doctor was now holding what must have been at least 50cm of silicone in his right hand. 

Still, no pre-cum was flowing out of that monster cock: there was just some wetness on the silicon sound and around the obscenely fleshy meatus lips. Bjorn saw that Nil's cockhead did not have a peehole anymore, but a fleshy, worn-out slit at least 1.5cm tall and gaping open. Though the doctor's penis was cut and also had no frenulum, the skin under the peehole was now slack with emptiness.

Finally, a thick stream of pre-cum came leaking out of that worn-out cockhole and started pooling inside the basin. Nils let out a low moan now, and pointed the dick down at the plastic bowl. The stream quickened and soon there was a torrent of pre-cum, cum and piss coming out from the huge member like water out of a tap. The pissing went on for a while, and stopped only Nils had let out what Bjorn thought was a litre of piss, cum and juices.

"Ah, much better now." said Nils stroking his still erect member.

"Fuck, doc. That was amazing." managed to mumble Bjorn, who was now stroking his own erect member, pushing more and more pre-cum on the floor and wetting his right hand and balls.

"Yeah, it aways is. See, what I have here is a pre-cum plug of my own design."

And he walked closer to come next to Bjorn, pulling up the plug to eyesight.

"I designed this before graduating, and prototyped it with silicone moulds I made myself. You see, here" - and the rotated the black shiny rod - "there are trenches sunken into the main circular bore of the plug, from around the depth of the prostate back until the bladder plug" - he was referring to that last, drop-shaped bead - "so that the pre-cum flows backward into the bladder. That way, my cock does not leak at all when I am wearing it, and I can last almost a day. The other beads are just to keep it in."

"Amazing!" gasped the young boy, looking at the doctor's proud, beautiful face while stroking his own meaty cockhead.

"Could I try it?"

"Oh Bjorn, this is made with a 2cm maximal thickness. I think it is too large for you. But I have other models that you could try."

"Fuck yes doc!"

"You seem a bit horny, Bjorn." said the doctor looking down at the young man's rock-hard penis.

"Oh yeah, you showing me your plug made me very horny. I really wish I could fuck my cock with some thick metal sounds, you know?"

And Nils smiled back to him, while with his left hand he was stroking his monster meat.

"I have some surgical sounds, if you'd like. Some Pratt sounds, some long straight sounds and even some van Buren ones that go deep into the prostate and bladder, if you like."

"I'd love that, doc." smiled Bjorn, horny and ready to give all of his body to that perverted muscle god of a doctor.

"Okay, then sit onto the bed while I take them out."

Bjorn then sat on the edge of the clinician's bed, his legs spread wide and his dick pushing upward in the air, still relentlessly leaking thick fluid on his balls and floor. Nils placed two metal cases next to Bjorn and opened them, revealing a set of long, hooked metal rods, and another set of slightly-bent, shorter rods. Nils started reaching for the Pratt-type rods, but Bjorn talked.

"Please doc, can you sound me into the bladder today?" he asked with an almost submissive voice now.

"You want me to fuck your cock deep, Bjorn?"

"Yes, doc, please."

"You like it when your thick, leaky cock is getting fucked from the inside with a large rod, don't you?"

"Yes sir. I like to push thick rods in my urethra until they get to my prostate and then to my bladder. I like keeping them there when I do my homework and sometimes when I go out shopping or working out, sir. I love stuffing my penis until I cum, sir."

"Very well, boy." This time Nils talked with a serious, firm voice. But the look was ever gentle, as it had been when Bjorn had set foot in that same room.

"Would you like me to teach you how to stuff that useless big cock of yours with the largest rods we can find? Making your peehole gape wide as mine, with fat pumped lips that prolapse out of your cockhead?"

"Yes sir, please teach me. I want to make my penis gape like a worn out pussy, even larger than your monster cock, sir."

"Then we shall do that, boy." Nils smiled at Bjorn, touching his left thigh lightly. Then the doctor raised to Bjorn's face and kissed him sloppily, pushing his tongue in the boy's mouth like a big, strong beast; putting his large gloved hand behind the boy's head.

When they stopped kissing, Nils moved to take a long straight urethral sound and moved the tip towards the wet peehole of Bjorn's cock.

"This is a 15mm sound boy. Let's see if we can get it to your bladder now."

Saying this, the doctor pushed the sound slowly into the hard boy-cock. There was no need for lube, because they both leaked so much pre-cum as it was. Bjorn knew well the cold thickness that was invading his hard member, and as it moved deeper into his urethra, he felt a rush of pleasure into his groin. There was some pain in there, too, because the rod was so thick, and Nils had to go slow, sometimes backing out a bit, but it was a good pain. He had learned to love the fullness of the sound. When the rod arrived at the base of his cock, Nils oriented it - and Bjorn's dick with it - in order to go past the curve at the taint. It went in smoothly, pushing within Bjorn's penis.

"Oh fuck, doc... ahhh" the boy moaned and purred.

"Lean back now, boy."

Bjorn did, and angling the rod once again the doctor pushed it deeper and deeper. Jolts of delight went through Bjorn's cock, balls and taint. Then the rod was at the prostate, and the young man let out a deep sigh.

"Fuck sir, you're fucking my prostate!"

"Yeah boy. Now be still and let me fuck your overgrown prostate like a good bitch."

To this, Bjorn moaned again and Nils began pushing the rod in and out of the boy's urethra. Slowly at first, then with deeper strokes, pushing the metal sound slightly deeper every time. Until, finally, Bjorn felt it pushing past the sphincter of his bladder, with a sweet, deep stroke. At this he knew he would be cumming in few strokes of the sounds, and so he moaned again and cried out in a broken voice.

"Sir-sir, you're gonna make me... cum."

Nils looked at the 20 year-old with eyes filled with deep desire and spoke with a low growl, pushing in and out the metal rod into the now half-hard penis. 

"Cum boy, push out your thick cum onto your Doctor."

"S-sir..."

"Yeah bitch, cum for me!"

And as he said this, the man started stroking the pre-cum covered cock of Bjorn. This last stimulation send Bjorn far up the waves of pleasure that were rocking his body from the core of his groin, flowing though him like flames flow in wildfire. When Nils saw Bjorn's legs twitching and his arch bending and turning, he readied the rod.

"Fuuuuuck!" screamed Bjorn aloud. His cock was swollen, and his peehole lips red and puffed from the stimulation. It pulsed hard, as the orgasm overcame the young man. Then Nils pulled out the metal sound from him, still stroking his erection, and a torrent of cum exploded in the doctor's face. Nils had opened his mouth and caught most of the warm, thick spray of sweet teenager semen. Then, as each rope spayed with less intensity from the swollen, gaping urethra of the boy's member, Nils put his mouth around the young cock and sucked hard for the 10... 12... 15! 16! and more sprays of cum that the spent Bjorn pushed out with satisfaction.

In the end, the patient lied spent onto the bed, sticky with cum, pre-cum and sweat.

"Fuck boy, that was a large load if I ever saw one!" said Nils licking his lips.

"And tasty too!"

He smiled and Bjorn smiled back. They kissed, savouring the taste and texture of that fresh semen load. The boy sat up slowly, his ass cheeks on the now-wet white lab coat.

"Fuck boy, now your Doc is pretty horny, too." Nils looked at that splendidly perverted twink naked on his examination bed. The man was stroking is monstrous 11-inch-long penis, which leaked clear drops from that leathery, gaping urethra.

"Can you take a cock in your mouth, boy?"

"Yes sir, but I never tried one this big..."

Bjorn almost finished his sentence, but Nils had already pulled him down from the bed, and kissed him hard. Then he pushed him tenderly but resolutely to his knees, keeping a hand on the back of the boy's head.

"You must learn how to take your Doctor's cock in your mouth, this is a very important part of your training."

Bjorn nodded, looking up at the muscular pecs of the physician, and upward into his eyes. He then put his lips around the monster cockhead, savouring the stronger taste of his doctor's seminal juices. His tongue naturally began looking for the thick lips of the peehole, which he had not had time to look up close, but he knew were thick and fat and juicy. His tongue tip found them, slightly gaping as before: just as he had imagined them. He pushed the tongue deep inside the wide peehole, almost as far as he could push it out naturally. There was an almost endless space into the doctor's urethra, and he wanted so desperately to explore it all, time and time again.

"Yeah boy, lick those pumped cocklips for me... Yeah."

He did so and then started to alternate between deep tongue explorations and swirling it around the fat, bulging cockhead. He opened his eyes and noticed then how much darker the doctor's member was in skin-tone compared to his skin. It was almost as black as coffee grounds, and he got even more turned on at the thought of tasting more of that dark man-cock.

"Now go deeper, boy." said Nils, pushing the head of the youngster down onto the remaining 9 inches of shaft, all engorged. His heavy ball sack way swaying now, touching his strong bulging thighs.

He pushed the cocksucker's head more, and Bjorn felt the cock pushing against his throat. Then, Nils began fucking the boy's head with steady rocking motions. Each push mean more and more cock was being pushed down the patient's mouth. Bjorn was almost gagging now, hoping for relief.

"Boy it's okay, it is normal to gag a bit the first time you suck on a real man-meat. Just push through it!" said the doctor, gently stroking Bjorn's face with a smile of pleasure.

The sour taste of that strong man's pre-cum was sending Bjorn in heaven, and his own cock, still hard, began oozing pre-cum like he had not cum yet. He was gagging now, his spit dripping profusely from his mouth onto his cock and on the floor, with wet sounds. His eyes dripped, too, from the intensity of the invasion. But he wanted that monstrous cock to go deeper into him, to desecrate him completely.

"Fuck, there we go bitch!" and the strokes got deeper and faster, the cock pushing down into his throat and into his distended oesophagus. Bjorn almost cried, but the pain was so good now, he wanted even more. Nil had both his hands around his head and was driving the dick relentlessly into Bjorn, who did not touch is dick and instead was massaging the round buttocks of the god Doctor, his Master and Teacher.

Suddenly, Nils pulled out of the young boys mouth, leaving him there, his face dripping saliva and pre-cum, his cock leaking obscenely.

"Let me prepare to feed you my cum, little boy. I need to do a thing first. I guess you will like it, too." And the man had a wide smile on his shaven, sweaty face. His whole body was gleaming with sweat in the dying light of the day.

Bjorn did not move, but looked, silently. Nils moved a bit then got down to squat on the floor, looking at Bjorn. Then, he used a hand to scrub the saliva/pre-cum mix off the shiny tiled floor in front of Bjorn, and began rubbing his asshole. Bjorn could not have noticed before, but now he saw that the doctor had a huge, puffed-up mound of an asshole. With a hand slick with body fluids, Nils started rubbing his hole and growling while pushing with his stomach muscles.

"You see boy, a man needs to train his manhole, too." Nils smiled again, in satisfaction. And Bjorn was speechless and aroused beyond his wildest dreams. 

Slowly, while fingering his asshole with the entire hand, the doctor pushed out a huge fold of red, shiny tissue, that kept growing and growing until 2-3 inches where showing out. At each breathing, the prolapse folded in an out of that obscenely distended manhole, each time bigger.

"You like my prolapse boy?" groaned the doctor.

"Yeah sir." gulped Bjorn.

"We will grow you one too, right?"

"Oh yeah... please sir, please." cried out the young man, with pure bliss in his tone.

"Can you take big dildos, boy?"

"I can sir. Every Friday I fuck myself with a big silicone dildo and a large buttplug."

"Well, we will need three private sessions - weekly - to get you there. Right?" spoke Nils, pushing his prolapse out again.

"Yes sir, thank you."

Now, after all the doctor's prolapse was hanging out of his man-pussy, almost touching the floor, Bjorn saw why the man was pushing out his guts. A large, rainbow-coloured egg made of silicone emerged from the prolapse, and fell to the floor. Loud farting sounds came from the doctor's ass, and a big gulp of ass mucus and possibly lube also trickled down. The egg was the size of a large eggplant.

"Aw fuck... just two more now."

And so Nils pushed more and more, moaning as he did so, and then another such monstrous egg was pushed out onto the tiles, with a loud pop. This time, a loud, long far let out of the red prolapse, which vibrated and burped out more juices. The doctor had a look of pure ecstasy on his face.

Then, he pushed again, harder than before. Breathing slowly, Nils pusher more of his guts out. He was now laying with his buttocks on the ground, his legs open wide and his hands on the knees. The monstrous cock was half-hard and leaning sideways on his belly, leaking a constant stream of piss and cum. His prolapse was spread out onto the floor. 

Nils moaned again, and a spray of piss jetted out of his peehole onto the floor next to the desk. His prolapse filled with another foreign object. As something was slowly pushed out of the prolapse rim only to be excreted with a final wet sound, Bjor saw that this was an entire dildo, with the suction base cut off. 

His doctor had had two silicone eggs and an entire dildo shoved up his ruined muscle ass all this time. Bjorn's twitched, and the boy knew another climax was close.

"Come boy, come get your hard-earned man-juices" said Nils, leaning back on the tiling.

Bjorn crawled, and put his mouth around the mid-hard 11-incher again. The doctor put his legs up and onto Bjorn's back, to guide his movements. 

"Play with my prolapse boy, touch it as I fill you up."

Bjorn did not hesitate, and started using his right hand to play with the trunk of red guts and the puffy ass-lips of his doctor. Nils' legs pushes the gargantuan cock into his throat again, and he was chocking and crying and fondling the nasty guts of that muscle god in front of him. Soon Nils was ready to fill him with his cum.

"Fuck boy here I cum!" growled the man, pulling the boys short hair with his right hand.

"Fuuuuuuuuuuuuccckkkk!!"

Bjorn could feel a flood of hot semen being pumped into his throat, over and over and over. again Then Nils pulled his cock out a little, but not much, so that his semen flooded Bjorn's mouth, too. It tasted intense and earthy. Bjorn immediately knew that he would never be able to stop himself desiring a new load of that thick man-cum. 

After minutes, and countless gushes of semen, Nils' orgasm subsided, and Bjorn could lift his head again. The doctor's prolapse had retreated into his humungous asshole, but his hole lips were still puffy and leaking with mucus. Bjorn was covered in spit, cum, and ass juices, and so was Nils, who raised up to sit on the floor, stroking his cock.

"Boy, we shall be having a lot of fun running your therapy."

"Yes, sir." nodded Bjorn.

"You can still call me Nils, you know." said the doctor, kissing the 20-year-old.
