Dan wandered to the mansion overlooking the small town of Green Valley. The mayor was real excited to have the researcher Adel Hemlock move in to the place, because her career left her with an exuberant amount of money, and now that she is a free agent- she is spending that money to do her own private research. Dan did not pay it much mind himself, but, now his own job fell through because the bar he was working at up till now burned to the ground. Turns out all the spilled alcohol made its floorboards extraordinarily flammable. Now with no work options lined up fast enough for him to deal with bill collectors, he spotted an ad in the paper from Dr. Hemlock- looking for human test subjects.

Adel was waiting for him already outside the mansion on the cobble path leading to its front doors, sitting in her wheelchair. "Welcome! We can get started right away if you are mentally prepared?"

"We- well, about the payment... I just want to make sure I got this right."

"I will cover the costs if anything unfortunate happens and we need to get it fixed- I find this an unlikely scenario. I have five other subjects already at various stages of the project and no one has had any problems thus far. You will be living here for the duration of the testing and I will provide food and all that, of course. You cannot however leave at any point- for any reason. These doors will not open for you till the test has concluded."

"But the actual payment at the end..?"

"You will be compensated for your contribution."

"So the ad said- what exactly does that mean? That's not a number."

"Well, average working wages, but there cannot be a specific number because I do not know how long the test will take- if it takes two days you get two days' worth of pay, if it takes two years you get two years of pay. It is a test- if I knew the exacts it wouldn't be a test anymore, would it?"

"Alright."

"Just... make sure you understand. When you go inside, you cannot leave again till this is done. And you have signed yourself up to give your body for my test."

He nodded; Dan did not have much choice. If he didn't hand over his body for science, the bill collectors would have taken his body piece by piece for themselves- starting with his kneecaps. The top of the mansion is where the other subjects were currently staying, but because Dan just got here he was taken down into the basement. Adel paused her wheelchair at the top of the long stairs and the seat detached from the rest, sliding forward down her legs and cupping the back of them as she stood up. The handles then folded over the sides and the back flipped down to link both back and side panels together, allowing her to walk down the stairs- as her wheelchair also doubles as mechanically augmented legs. The basement is entirely full of lab equipment and many alchemical stations using a gradual infusion of local mana to enhance and project the natural effects of various materials- organic or otherwise- into liquid solutions.

Adel gave him a quick injection and then motioned to a room at the back. "You can just hang out in there till it is done. There isn't anything in the room really, but the effects should be quick so you shouldn't have time to get bored. Once the initial effects have taken hold, you can move upstairs in the regular house with the other men."

"You don't need to observe me or anything..?"

"Oh, I do- but I do it remotely from the lab. Most people find the layer of removal helps them cope with embarrassment. The entire building is monitored from my lab."

Dan sat down on the cot in the room- the only thing in the otherwise barren box. The room is entirely made of metal so it is rather aesthetically cold. Even the cot has no sheets or pillows. Dan was not sure he felt anything off or not. He was expecting something weird to happen, so he was sort of psyching himself out and twitching at nothing. What was going to happen? Is he going to grow scales, or an extra arm or something?! Hopefully something that can be reversed, or at least something that isn't outwardly obvious so people don't think he is some sort of freak. Dan shifted his sitting position a bit as he felt his taint push back against the stiff mattress under him and decided to lay down and just relax till the potion prevented him from relaxing.

His taint stiffening progressed into his shaft as his penis slowly engorged, bending itself straight in his underpants and then sliding up. He wasn't thinking of anything in particular, and there was definitely nothing erotic about his scenery so it seemed weird to get an erection from seemingly nothing. Dan flinched and immediately stuck his fingers under his pants to scratch an itch on his groin over his penis but felt something off. He pulled his hand back to see his pubic hair- fallen out! He scrambled back up into a sitting position and yanked his pants down in the front, wedging the waist under his nuts so his balls held it down without needing his hand. All his pubes fell out- or more accurately; they were pushed out. In their place was a mat of new hair- a bit shorter, a lot denser, and freakishly soft... it is not hair now, it is fur. It spread from the base and consumed his balls as they rocked back and forth gently in the scrotum, getting a tiny bit bigger with every motion! The fur started to advance up his shaft as well, but as it did the skin of his shaft seemed to tense; recoiling from the feeling! His foreskin pulled itself back even further than it normally could simply by having an erection, and then pulled back even further! It bunched up at the base, compressing into much thicker skin as the fur consumed it entirely and stopped there- forming a sheath where there was once a foreskin!

Dan moaned unintentionally at the sensation of his shaft sliding further out away from the skin that was once his foreskin. The shaft below a bit darker red. The thicker veins in his shaft seemed to spread out- becoming more numerous but also much thinner in the process. He also felt something like a knuckle popping, but from his lower back! His tail bone started to stretch out into an actual tail! It was growing the same golden fur as his crotch now had, but the hairs on the tail were getting much longer! His shaft started to swell up thicker in the middle which put pressure on the corona of his glans- because his glans did not expand with it. The shaft under it pushed up and out enough to completely equalize with it, hiding the ridge entirely before the pressure increased enough to pop it in reverse! The glans of his penis were now concave, not convex! But his dick felt like it was trying to erect itself even more, even though the skin was already at its limit! The growing pressure was concentrated into his urethra alone, and it slowly started to rise up, pulling a bit of the skin up around it to create a rounded conical protrusion! He recognized that shape from people's rowdy pets! That is a dog's penis! At the realization of what happened, and the changes having stopped- his penis started to soften slowly and return to the sheath now. His balls were almost twice the size they were before too- his scrotum now filled to be quite snug; they cannot roll around much anymore. Dan quickly looked back and sure enough- there is the golden tail of a dog wagging behind him. Why is it wagging?! Isn't that supposed to mean he is happy? He isn't happy. He also did not appear to be changing anymore either though. Just tail and genitals? The heck does that test?

He heard the door open and looked over as Adel walked in. "Alright, if you want you can proceed upstairs. This will be all for the initial dose so you don't need to be in this uncomfortable box."

"W-what did... is this reversible?!"

"The dog traits? Yea. You never heard of transformative tonics? Hm, I suppose Green Valley is a pretty remote town from the capital."

"So it is all reversible?"

"Yea. It also isn't the test though."

"W-what?!"

"Well those tonics have been around for a while- there is nothing to test about those, haha. No, this is just the prep stage- the actual test potion is much more gradual."

"So then what is-?"

"Fertility! Male fertility and virility."

"Oh." He nodded half to himself; that did not sound bad at all. "Wait, then why do I have dog junk?!"

"Because I already have a human test subject, I needed to test canine males too."

"Then why didn't you get an actual DOG?!"

Dr. Hemlock laughed, patting his shoulder. "Because a dog can't sign a waiver of rights, silly! But you did."

And with that, she led him back upstairs. Being a mansion- there are many rooms around the large building, so the other men were not around when Adel brought him up- each was off elsewhere in the house of cooped up in their room. Adel informed him that he would likely not see her much for a while- she had lab assistants to actually tend the needs of the 'guests', but Dr. Hemlock would remain downstairs in her lab observing everything remotely.

Dan did encounter the others that afternoon at various points- wandering the mansion to see what there is to do. There is a very nice exercise room, a substantial library, an entertainment room with a television and a good collection of VHS, even a large indoor garden if you just want to shut your brain off and water plants. The dining hall was gigantic and several sections of the mansion converged on it. There was one bedroom upstairs and six downstairs- since there are six test subjects the upstairs master bedroom was filled with several beds and housed Hemlock's assistants. The six bedrooms downstairs were broken into two halls- either hall had its own bathroom. Dan first encountered Lance, who has a thin tasseled tail- by tail alone he could not guess what species Hemlock had given him, but he wore a bedsheet tied around his hip because his genitals were far too colossal to fit under pants. Based on that alone, Dan was able to deduce Lance has the genitals of an elephant- though because his torso is still human, the testicles are external still. Next was Peirce whose corkscrew tail was so short it was barely visible from under his shirt in the back- but the front of his pants filled considerably not by cock but by enormous balls of a domestic pig. Clyde has the long flowing tail of a horse, so there is a good sized bulge in the front of his pants too. It was dinner time and when everyone gathered to the banquette hall for the meal that Dan finally seen the other two. He also saw the assistants too, since they were the ones serving the food. Lauren, Rael, Tiff, and Lucy- all quite good looking and looked to be early or mid-twenties... too young to be a researcher on-level with Dr. Hemlock. They likely aren't direct assistants to Adel, but more likely apprentices. With a sizable bulge in his pants; the only pure human subject is Norman... the bulge is likely the fertility part of the test kicking in, since his junk is supposed to be fully human. The last is Orwell, a quiet man who did not speak a single word through the entire meal and immediately returned to his own room after. Like Lance; he wears a sheet tied around his hips as his endowments are well beyond what any human clothing could possibly contain- but unlike Lance it was easy to tell his species from his tail- he is part Blue Whale. He has a dork under that sheet bigger than Lance's elephantine phallus. The biggest dick on the entire planet, in fact.

The only television in the place was in the media room, not any of the bedrooms, so most of the guys took books back to their bedrooms if they wanted to keep to themselves, because watching television meant being around the others. It isn't that they were anti-social, but more the fact that they have giant animal genitals, which is embarrassing to be seen with. Dan was feeling really pent up by the time night came around, but since the test was on fertility he did not want to masturbate only to be asked to produce a sample a short while later and then not be able to. For that reason, he decided to go to bed early. He could ask one of the assistants about it tomorrow. His dreams were understandably erotic though, taking his horniness into the world of dreams with him. In the real world he was lightly humping his mattress, and his tail was wagging so energetically that he bat the blankets off of himself. His balls very slowly started to increase in size as well. The slack of his scrotum vanished, and the skin remained only loose enough for his balls to jiggle and bounce in their confines when he humped the bed. Eventually he woke himself up in the middle of the night, groaning and then very quickly jumping up to the side of the bed when he felt the wetness!

Dan thought he had pissed the bed for a moment, before realizing it was pre cum... just a freakishly large amount of it. He groaned and placed his hands on the sides of his nuts- they felt so hot. He could almost feel the pressure in them beating against the base of his cock like water against a dam. Every throb of his hard cock it burbled up more salty lube. Now that his erection was so strong he also noted another part of his anatomy he missed on first glance- the sheath is bulging out massively by a knot barely contained inside. He was not used to feeling a scrotum covered in fur either, and idly pet his balls. His cock started to throb harder with each pulse. Dan was not even touching his penis, but the feelings were still slowly edging him closer. His tail was unconsciously wagging so fast it was fanning his back, preventing him from sweating. Dan's balls seemed to clench a moment on their own but then swelled outward in a short burst! A very long stream of precum oozed from his dick and the shaft started to vibrate. Dan was wide-eyed and his hands hovered off his balls now, afraid of setting himself off. He watched as his knot slowly started to slide out, and the moment it popped out of the sheath on its own his balls yanked into his crotch tightly and he absolutely erupted cum! He leaned back just fast enough that the first blast of cum did not hit him in his own face. He fired off rope after rope of cum and it took about a half of a full minute for him to stop! He never even touched his shaft, and he just exploded! Maybe that is why the bedrooms have tile floor. With a groan, his tiredness hit him even harder now and he decided to go back to sleep for now- worry about the mess tomorrow. He had to switch to the other side of the bed, since he soaked the first side with his lube.

Dan ended up sleeping in to noon the next day, so when he woke up again he already felt pent up! Not quite as bad as the night before- he was not leaking profusely, but he did still feel quite full. Not wanting to erupt unintentionally at an inopportune time- he decided he better take care of it deliberately while he was here. His penis did not take long to coax out of the sheath, but he flinched back when he touched the shaft. It was a lot more tender than he was used to- because his penis wasn't used to sleeping in a sheath all the time before. He had to grip just the base through the sides of the sheath and use that to draw up some precum for him to use as lube before actually grabbing the shaft directly. He can't masturbate with dry hands, not with dog genitals anyway. As soon as the knot started to engorge he pushed the sheath down to pop it out quickly. The knot is twice as sensitive as the rest of the shaft, and shoving it down or pulling it up sends a hot wave of pleasure through his entire groin. Once it is fully out he grabs the knot between his middle and index finger crooked around the bottom and tugs gently up. The pleasure spikes so quickly touching himself there that it doesn't take long at all for his balls to release another massive load onto the floor- so he had to clean up twice the mess afterwards.

In the banquette hall at lunch only Lance and Pierce were there- the others skipped. There is way more chairs at the long table than there are people in the mansion, so they all sit staggered apart. Dan has to sit further forward on the chair than he normally would so his balls are hanging off the front and not on the chair with him, because of their new size. So the test was on fertility... so he would be getting off a lot? Actually sounds like a good time- but he still doesn't know what the protocol is. Is he supposed to be getting off? While he was pondering this, he heard Lance groan and shift in his seat at the very far right side of the table. He had been sitting with a leg folded under him but shifted to put it down and when he did the table shook and hopped up off the floor for a moment! He must have an erection under there- his dick is so enormous it slammed into the bottom of the table with enough force to LIFT it.

Lance blushed and spoke in his very deep voice. "S-sorry."

The touch against the table caused his erection to harden further, pressing again into the bottom of the table no matter what angle he held in his chair! He has bronze skin, a bit of a belly on him, but strong arms and a lot of tattoos- he looks like the type of guy you hire as a bouncer for a club. Lucy quickly skittered over to him from the door to the kitchen and asked if he needed a hand. Lance just blushed even harder and nodded. She helped him up and he had to try and shuffle the sheet around his hips to cover his shaft as he walked away, but because his dick is sticking straight out- you can easily see under the sheet still. Each of his balls are the size of a basketball at least and his scrotum is heavily wrinkled. His dick has a mostly blunt end on it, and a slight fold at the middle where it folds in on itself when flaccid. His sheath isn't very bulky since it's fully out. The dick itself is a bit longer than his entire torso, and as thick as his thighs! Elephant phallus are also apposable- he can control how it bends and move it around. Seeing Lucy help him though- that made Dan wonder.

Dan raised his hand and waved toward Lauren still by the door to the kitchen. "H-hey...?"

She hustled over to him- since he is sitting on the opposite side of the table. "Yea? Need a hand?"

"Ye-well... what does that entail, exactly? I am not really sure on the protocol here. Do I need to be like, saving samples or something?"

She shook her head. "No, we do that. We will collect samples when needed. You don't need to do anything really. If you get too full, you can just call one of us women and we will help empty you out~"

"You're here to have sex with us guys?!"

Lauren glanced away a moment. "Well... not sex. But there is more than one way to milk a stud."

"When... do you guys need to take samples? Because I accidentally sort of already emptied out..."

"Oh. Well, depends how the test results progress, but we are supposed to take one in two hours. It is okay- you should have another in you by then."

After lunch Dan got a bit nervous, not sure what to expect entirely or what to do when the time came. Two hours passed by like two minutes. Normally he would only masturbate once or twice a week, so doing it just two hours after having already done it the same day seemed a bit much. He was not feeling pent up, but his red rocket was peeking from the sheath- unintentionally arousing himself by the thought of one of the women coming to tend to him. It also looked like his balls may have increased in size again by a bit- they were both about the size of a softball. Considering he is the last guy to have signed on, and was mixed with the smallest species- that was pretty damn big.

When the knock on the door finally came, he almost jumped off the side of his bed in surprise. He had a book open but was too nervous and aroused to actually read any of it. It is Rael that stepped inside and quickly shut the door behind herself. She looks the youngest of the four women, and is adorned with a few tattoos and many piercings.

She held up a small clear ball. "Alright big guy, we need a sample for the doctor to look at on a microscopic level, so I am going to need to empty those tanks."

"Do I...?"

She smiled and shook her head. "Just lay there, let me do the work."

The ball is made of a flexible material known as Harvet- it is a type of memory material. The molecular arrangement only makes sense when arranged in this shape- so if you bend or even break the surface it will immediately mend itself, because this is the only shape it can be in without outside force interrupting it. That means his penis can penetrate the thin rubber like surface, ejaculate into it, and then the moment he pulls out the gap his dick created is gone, and his cum still trapped inside, since it is hollow. So it is sort of like a condom only more meant for storage and transportation of fluid mass rather than simply containing it for disposal.

Rael gently nudged him back to lay on the bed and climbed up over him, then sat up to undo his pants, smiling at his package. Dan nervously wondered if that smile was because she liked what she seen, or she thought the canine equipment on a human looked silly. It was a strange thing to be worried about, since this isn't even his penis really, just another penis' shape forced onto him. He could feel his tail twitching under him, but it was luckily pinned under his weight and could not wag- THAT would be embarrassing. It did not take much to set that thing into motion. Rael gently cupped his balls and heft them, then gently wrapped her fingers around his sheath and pulled it up and down softly, causing his shaft to slowly slide out. He was aroused enough to immediately go hard without help- but his embarrassment was reigning it in. She apparently knew canine anatomy too, because she was also quick to lure out the knot. Once it was out however, she started to undo her own pants! Wait- didn't they say no sex? Well... technically it was Lauren who said that earlier, not Rael. Rael did look the part of someone who likes to break the rules. An amethyst jewel hung from a small chain in her belly button, then below that a bushy tuft of black pubic hair and a tight pussy with puffy lips- looking almost like it was pursing for a kiss. She held the tip of his dick up along his body, so she did not mount his shaft, but rather sat her plush labia down around his knot! Rael started to rock her hips back and forth, making him moan in pleasure! The knot felt impossibly hard- harder than his shaft could even get, throbbing in a sea of soft, moist flesh folds. Her body blocked his view- but his balls pushed against her lower labia every time they rocked up toward his crotch, and swelled a tiny bit bigger with each trip. The felt so hot, so... full. He groaned and his cock started to spasm erratically. Rael quickly grabbed the golf ball sized orb of harvet and popped it over the end of his cock! He erupted into it, and it immediately started to stretch out even with the first burst alone! By the time he finished cumming, the orb was the size of a honeydew melon in her hands! WOW, all of that was in him? After just having an orgasm only two hours ago?! The fertility treatment must really be working.

When Rael told him he was a 'good boy' and left, he could hear another of the men groaning in pleasure down the hall before she closed the door again. They were all producing samples around the same time. Dan wondered how the women even collected on some of them. His junk was a completely different shape now but not really any bigger- meanwhile there was a whale and an elephant among them. How do you get off a dick bigger than your entire body?!

At dinner time, Norman was the last to the table, and Lucy needed to help him to his seat. He is pantsless and fully nude from the hip down now- so Dan could easily see why. Though his penis looked like a normal seven inch human dick, each of his balls were nearly the size of a yoga ball. There is no room for either of them between his legs, so when he walks his thighs have to lift either testicle in order to move, causing his scrotum to slosh one way and then the other as he moves, which is why he needs help. All of the other men were uncomfortable looking at that. Norman was the first person here so he has been exposed to this the longest, but he was just normal human. If his nuts are the size of yoga balls, and formerly the size of chicken eggs... what is going to happen to Lance, whose balls are already the size of a basketball each before enlarging at all?

When Dan finished dinner he went to the bathroom and thought about that himself. He almost sort of... felt pent up again. It may just be because it is hard not to accidentally give himself a boner, when there is so many things of a sexual nature to think about. He did not want to overdo it and masturbate if he did not need to. But it also felt great to cum so much. His penis started to slide out of the sheath as he looked at himself in the mirror of the bathroom, spaced out. If he does it- he should do it here so he doesn't have to clean up a mess too. But there is only one bathroom for three subjects, so he can't rely on coming here later or being in here for long. He bit his lip nervously for a moment, and felt his balls do a little hop in the scrotum, caving in and deciding to sit down and work one out. A fourth time in a single day- yikes, quite the increase. Dan was easily worked up and was almost disappointed by just how quickly he was able to set himself over the edge! Normally cumming into the toilet would send a few ropes into the bowl- the streams of cum this time hit so hard it blended with the water and turned the entire bowl solid white! When he flushed it moved in slow motion because the consistency was too thick to move normally, almost clogging it with how much cum was in it!

He went to sleep that night feeling satisfied and emptied out, but... that feeling would not last too long. Like the night before his dreams were a blur of sexual concepts. At least this night he managed to stay asleep all the way till morning. But as he slept his balls slowly got a little bit larger again, making quiet gurgling sounds as their capacity increased and then filled. The next day Dan woke up and immediately had to masturbate again, dashing to the bathroom quickly to take care of it, walking a bit weird because he was not used to his nuts being so big so he was afraid he would accidentally crush them between his thighs. He heard some splashing and remembered there is a pool in the exercise room and decided to wander down that way to check it out.

It is a large room with a curved roof that becomes the far wall- entirely made of glass panels so you can see the forest behind the mansion. Orwell is unsurprisingly the one in the pool right now- his whale tail makes it easy to swim, but harder to walk- it is so long that it drags on the floor when he walks. He is a tall guy but not muscular or fat so he is sort of just a bean poll. He is completely nude while swimming, since no swimming trunks are going to fit him. Dan almost thinks there is a second person in the pool with him, but it was just his giant half-chub dick tailing behind him. He seen Dan but did not say a word, again. Dan just started to pump some weights to pass the time, watching the clouds slowly drifting over through the glass roof. His attention was drawn back suddenly when Orwell groaned and splashed in the pool. That might be the first sound Dan heard him make. Dan looked over but then half-averted his eyes when he seen the giant pink pillar of meat waving in the air! Orwell was floating on his back now, his hips making micro-thrusts at his very sudden erection- but it wasn't induced by arousal. The very fat veins toward the base of the gigantic phallus seemed to dig further into the shaft, bloating out further up and the entire dork swelled larger as a result! Already an insane 6 feet long, it was stretching even bigger now! Whale phallus is mostly a tapered pillar, though there is a subtle fold at the halfway point as with any animal with an extraordinarily long dick. His dick size was not the only thing changing however- it was hard to tell through the rippling waves on the surface from his thrashing, but Dan could tell the amount of discolored skin on Orwell was increasing beyond just the base of his tail.

Orwell quickly grabbed the side of the pool to steady himself and with quite a bit of effort he managed to drag himself back onto the floor beside it. His tail was almost three times the size it was before! It is so wide at the base it forced his legs apart and partially fused to them, causing his leg shape to change and devolve partially into flippers! The color of his skin was looking dark violet on his entire lower half- the skin of a blue whale is... well, dark blue- but his peach tone human skin is still blending with the color partially. He ground the base of his dick into the floor aggressively, trying to use the hard and cool floor tiles to punish the phallus and rein it back in. The veins at the base were stretched thin enough on the surface that they were looking like a pastel violet as well. At the side of the pool, his dick was so long that it took up all the room between him and the wall and was forced to bend sideways against the wall to find room. His scrotum is so smooth it is shiny, and held tight against his body- normally a whale's nuts are entirely internal, but since his torso wouldn't fit whale nuts; his are still external.

Tiff scrambled into the room a moment later to tend to him, and quickly asked Dan if they could have a bit of privacy. He wanted to ask what was going on, but they seemed understandably flustered and in a hurry to deal with it, so he held his tongue for the time being and left the exercise room to them for now. Orwell suddenly became more whale... and more endowed- but that was likely just because he was more whale. An actual blue whale would be big enough to crush the entire mansion, so if he suddenly turned all the way- EVERYONE would be in trouble.

Dan wandered to the entertainment room instead, and seen Lance looking rather intently at the television, leaned toward it with his elbows and knees touching. Lance almost appeared to be looking through the TV, lost in thought. Dan was trying not to look at the giant phallus draped across the floor in front of him. It was not entirely erect so it still followed the curve of the top of his balls, but still had enough length left over to fully rest on the floor- outside of his sheet's ability to cover. Because Dan was trying not to look at it, it took him a few moments to realize that Lance was actually growing! Not just his dick but his entire body was getting bigger! His nails became tremendously thick on his hands and feet, and the skin started to turn grey.

Dan put a hand on his shoulder and gently shook him. "Yo, you okay man?!"

Lance suddenly snapped out of it and sat up, looking around like he had just remembered where he was, then looked at Dan and nodded- still looking a bit confused. His size increase started to reverse just as quickly as it happened. While his dick and balls shrank back- his balls were still larger than yesterday even after the current increase was undone. Each ball was big enough to lightly touch the floor in front of the couch while he sat on the couch. His extremely girthy, soft shaft lay in the crevice between made of soft scrotal flesh strung between the balls like a cock-hammock. When fully packed away his sheath is so big around you could probably fit a fire hydrant inside of it. Orwell still has him beat at least twice over in dick size, but their ball size is about equal at the moment.

"S-sorry." Lance shuffled over a few inches to the far side of the couch so Dan could sit on the near side. "Bit tired, so harder to keep my concentration."

"What was that?! Orwell suddenly started to turn more whale too in the pool!"

"Yea... right, you were the last one to sign on. Well, Adel used animal transformation potions on us, which normally turn you into the animal... but she only needed our genitals to change and nothing else. She found a way to isolate its effects, but it is against the potion's default function so... if you act or think more animal, you can turn further into one by accident. When you snap out of it, the features regress again to just your junk and tail." He sighed, leaning back further onto the couch instead of forward. "And it is harder for me, because elephant isn't that far off human, mentally. If I space out at all I can start to shift. Orwell lost touch a bit because he was in the pool- swimming around like a whale. Me and him turning can potentially be outright dangerous- since those animals are big enough to crush and kill people by accident."

Dan was a little nervous about that- and knowing he could potentially turn more dog by mistake. "When... when does the test end? I mean, I know the fertility thing worked on me, and I was the last one on. Doesn't that mean we are technically done already?"

Lance shook his head, flipping the channels. "The test is still going. It will continue till everyone stops changing, so it isn't about whether it works or not, it is about how well it works too." Lance huffed, glancing at Dan. "Which means technically we are all waiting on you. Because even if we stop enhancing- none of us leave till ALL of us can leave, so you need to stop growing too."

After a while of watching TV, Lance also mentioned being a bit worried about Norman. He had trouble walking the other night because his balls had grown so enormous- and no one has seen him today at all. If they grew even bigger- he might not even be able to leave his room anymore! Lucy has also been missing all day- likely tending to Norman. If a purely human subject can get that big... what does that mean for Lance? Adel also said that the animal aspect is easily undone... she didn't say whether the fertility enhancement is reversible or not. What if their balls stay that size?!

After a while a quiet squelching sound came from Lance's balls- the ribbing of thick flesh on his scrotum threatening to pull flat from internal pressure. He grunt and said he needed to find one of the attendants and left the entertainment room to Dan. When Lance walked, he grabbed his scrotum from the front and held it up a bit to give his legs room behind it. Dan looked nervously down at his own balls once Lance left. Did... they look bigger already too? When it happens gradually it is harder to judge the difference. He felt a bit full and easily aroused but chose to try and ignore it- he was nervous about unintentionally promoting the change. He liked the idea of more and bigger orgasms, but... there was a limit before it becomes unmanageable. Every time he touched his balls he could not help but pet them a bit- still not used to the fur coating. Dan started to leak a bit of pre, then became flustered remembering where he is. He glanced around- no one was around to see him right now, but there also is nothing in the room to clean himself up with. Seeing no other option to clean himself off before he messed up the couch- he used his fingers to wipe it off and licked it off his fingers. When he stopped though, he hovered his hands there in the light of the TV screen- noticing his nails are now black. Slightly more narrow, a bit longer, a LOT thicker, and solid black; he has the nails of a dog! Licking himself clean is a very animal thing to do. He quickly put his hands down at his side and stared at the TV. It would go away, right? He will turn back if he just doesn't do anything else dog- its fine. No one will notice a little thing like that.

Dan ended up leaning further and further forward as time went on just like Lance had, just so no one happens to walk in and see his increasingly engorged dick. He was doing his best to distract himself with the TV, but he was still getting a boner is super slow-motion, as his balls felt more and more full. He felt them pressing on his thighs and thought they were just filling up, but that isn't really how balls work in the first place- they are filling up, but the reason they are pressing more on his thighs is because their actual size is also growing slowly. Peirce walked by after a while- they both muttered a hello but otherwise barely acknowledged each other. Unknowingly for the same reason- they were both distracted with unintentional arousal. Peirce was not staying in the entertainment room however- he was just passing through because the stairs up to the garden was on the other side. The garden existed on its own floor- a glass dome at the top of the building. The entertainment room, master bedroom, and library were on the top floor- so each successive floor is half the size of the previous one. Dan had to lick up several more dollops of pre to keep them off the floor. His balls were starting to do pull-ups in his scrotum and he could feel the weight increase as they flopped over the front of the couch and tugged on his crotch, which pulled on his sheath and made him feel every twitch of his shaft that much more. Dan finally gave in- not wanting to devolve his hands into paws by accident just to keep from making a mess. He got up and dashed back downstairs to go to the bathroom and empty out- hoping no one else was in there at the time doing the same thing.

He passed Clyde on the way out, but did not think anything of it. He was actually on his way to the garden too- but neither he nor Peirce were there to smell the flowers. There is six subjects but only four attendants- who also need to do housekeeping, errands for Adel, and cook meals. The two had become so desperate to get off once that they turned to each other for help. Turns out Clyde is gay, and while Peirce previously thought of himself as straight- he is second guessing that now. Pigs already have very large balls for their body size, so by now Peirce's nuts were like pink beach balls! His scrotum was tighter in the back however, causing his balls to sit more naturally behind his legs rather than in front; since they definitely do not fit between. That made it easier for him to still walk than the others at this size. Peirce himself is ironically the lankiest person here-borderline gaunt- making the huge spheres the curviest part of his anatomy by far, and that much more obvious. Clyde is more true to the species he was mixed with- very muscular, though missing his right arm just below the shoulder- he has a metal cap over the scar, bolted straight through the remnant bone. He is an ex-city guard; forced to quit because his sword arm was bitten off by a Manticore. His skin is a dark brown, while Peirce is a rosen hue.

Peirce scoot his pants off- his genitals already were outside of his pants perpetually anyway because they can't fit inside anymore. "I am still not... sure about all... this. But I need to empty out and... and..."

Clyde chuckled in his gruff voice. "Who are you making excuses for, exactly?"

"Well, I just... never did anything like this before, and the whole situation is... hnnngh." He danced back and forth on his trotters a moment, a lazy trail of pre connected itself from his dick to the floor. "J-just... give it to me."

Clyde raised a brow, just now noticing that Peirce currently doesn't have feet. The skin on his legs blushed pinker than the rest of him now and his feet fully regressed into pig trotters- though his leg proportions are still human or he would be several feet shorter. This ham haunch was too tasty a morsel right now for Clyde to bring up a topic other than sex, so he ignored the animal trait for now.

Clyde walked up behind him- his own pants long gone, already too big to bother trying to wear them at all, though he still wore a shirt, as did all the other men. They are the same height, but Clyde bent forward a moment so when he walked right up against the pig and stood straight again- his large equine phallus lifted up under him between his legs and pressed into the underside of Peirce's own shaft! Peirce's giant balls pressed into the pocket of Clyde's lap and prevented him from pressing completely up against Peirce, but felt great to rub the base of his shaft against. The skin is taught and smooth, so Clyde had to fight the urge to simply hump away at his scrotal-cleavage alone- like the male version of a tit-fuck. Because his cock has to travel between the balls and across Peirce's taint- even the enormous horse phallus can only reach as far as the end of Peirce's sheath in this position. Peirce's porcine penis is quite long itself, but very narrow, and the last third of the shaft has several spiraled ridges, making the dick itself resemble a corkscrew. Clyde gently rocked his hips, rubbing the two dicks together from below till Peirce was fully rigid. Peirce moaned and bowed forward, thrusting his giant balls back. Clyde chuckled again, thinking that if the man's balls were any larger, he could almost sit on them as a chair.

Peirce bent over using the edge of a huge plant pot to brace on, spreading his legs so his giant balls bobbed forward as far as he could get them, almost sitting between his legs. The room is very well sit since it is the middle of the afternoon- the garden has no true walls, it is entirely glass. Since it is also the third floor, of a mansion that is already up on a cliff at the edge of the town- you can see the forest behind and the entire town down below; but the garden itself is too high up for anyone on the outside to be able to see back into. It is also a fairly safe place to do a little romp like this- because it is too remote for the sounds of their moans to be heard by others, and there are a short flight of stairs and then a ladder leading up here- if someone else were trying to get here, the two of them would hear them coming up the ladder first.

Clyde placed his hand on Peirce's lower back, bowing his hips far back to line up the broad tip of his very large cock. The longer the dick; the harder it is to aim properly. At over three feet long, Clyde's dick gets places before the rest of him can. It is a near-black shade of brown across the balls, sheath, and lower half, but the area between medial ring and the corona has a large neon pink patch of skin on the top side of the shaft only- a steep contrast to anywhere else on his body, making it stand out like a sore thumb. The closest skin tone he has anywhere else is the inside of his hand, which is more of a dark red than pink, the rest of him is either brown or extremely dark brown. His balls were the size of oblong softballs by default, but that was two days ago now- NOW his balls are each the size of an oblong medicine ball and he loved the feeling of their weight when they swing! His scrotum is smooth and shiny like Peirce, but unlike Peirce the scrotum is much looser, so they can be swung around easily. As soon as Clyde thrusts in, their balls slap together with an audible *plap* and they both moan in unison. Clyde pulled him forward with his one hand and Peirce angled his hooves further forward putting his legs at an angle that let Clyde get his shaft in fully without grinding against the giant high-slung balls. Now Clyde's own bulbous nuts fit perfectly into the top pocket between balls and taint every time he thrust in, brushing the bottom of his balls along the back of Peirce's. They started to fuck with earnest, and the force of their thrusting together stirred the air- causing the smell to abruptly swap between flower scented, and masculine musk. Because their large balls fit so perfectly together, when they collide it makes a hollow *pop* sound as they clap together, like someone clapping with cupped palms.

Peirce's hungry hole became sloppy wet very quickly from the amount of precum Clyde was producing- while Peirce unintentionally overwatered the plant he was bending over. Since his dick is so long and he is bent so far over, he bowed his head and managed to get the very tip of the porcine phallus into his mouth! Peirce was able to partially blow himself while Clyde stretched Peirce's ass around his massive cock like a living condom. Clyde smiled while breathing heavily and flicked the corkscrew tail on Peirce, watching it bounce like someone flicking a door-stop. He noticed the man's butt start to look shiny and the skin starting to blush pink. Is he... turning more pig? He felt the ass cheeks round out a tiny bit bigger and fatter with each thrust, which turned him on even more and caused him to thrust more aggressively, forcing Peirce to really brace himself hard. The aggressive thrusting took its effect on Clyde as well though- and the bridge of his nose popped and became much wider, his nostrils flaring huge! His hairline started to slowly tickle the back of his neck as it extended downward in a narrow line, forming a pseudo-mane. Clyde groaned as he started to jet precum almost like he was already having an orgasm, and his balls groaned quietly themselves as they increased slowly in size! Then Peirce's nuts did the same! They were practically taking turns growing in tiny surges. Peirce let the tip of his dick out of his mouth and groaned, drooling pre onto the floor- his stomach starting to feel full from the amount of his own liquids he has drank already!

Peirce orgasmed first, having his prostate milked by the behemoth horse dong. His giant balls clenched up, but because they are much larger than Clyde; Peirce's balls cupped and pinned Clyde's balls to his taint! Having his testicles gripped by another pair of giant balls sent Clyde over the edge and he erupted into Peirce! The difference between the two is Clyde exploded like a garden hose turned on full, and after about 10 stuttered streams, he finally tapped out and fell back to catch his breath. Peirce on the other hand would not be able to stop for some time- his balls are both far greater in size and his penis considerably thinner. His cum ejaculated in spurts just like a human, but was a thicker consistency and he had an absolutely enormous supply... but can't remove it any faster than a human. Spurt after spurt, his balls bobbed up and down while his shaft vibrated, one minute after another. Peirce cannot stop cumming for a full seven minutes, and by then he is understandably exhausted and his leg muscles turn to jelly. And that is the least of its effects- pigs orgasm for a half hour or more at a time, so if he turns more pig and/or his balls get bigger, his orgasms are only going to get even longer and even more exhausting. Once they were both catching their breath, collapsed on the garden floor; Clyde's face made a soft crunching sound and seemed to collapse back into its human shape. The pink started to fade from Peirce's rump as it shrank back to normal and after ten minutes finally the bones in his lower legs started to crunch and branch apart- breaking up and returning the hooves back to human feet. Neither of their balls regressed however- the size increase there remained, because that was not an animal trait; that is the fertility treatment.

Meanwhile Tiff finally got Orwell to his bedroom and wedged through the doorway- he is both larger overall and his enormous tail and de-evolution of his legs put them much wider apart, which forced him to squirm from side to side to get them through the doorway, because he cannot pull them in far enough for them to both fit at the same time. This awkward middle-form also prevented him from being able to lift his back half off the floor at all so he was essentially dragging himself... except his genitals also cannot retract into his body like on a normal whale, so he was dragging his weight over them too- so he had to be REAL careful. When Tiff helped him into bed she rolled him over so she could have access to his dork, and his weight caused the bed to stand up when he rest on it, and then the two bottom legs snapped off entirely- so the bed was partially broken and wedged under him and against the wall at a diagonal angle. Oh well, that was as good as they were going to be able to get that.

Tiff shivered at the sight. "Hoo boy... big boy. Really, really big boy."

Orwell grunt, trying to reach his own immense shaft from his laying position- the arch of it put it so high up over him that he could barely reach.

Tiff slapped his hand lightly to keep it off. "N-no, let me. I can still do it... I think. I want to try! I am just... nervous."

Orwell has long red-brown hair, but it is curly when it is shorter, so the length causes the curls to bunch up into large licks of hair, causing it to look completely wild and untamed. He has a tattoo of spell runes down the middle front of his torso- a necromancy spell; a deathweaver curse, if completed the spell will instantly kill anyone it is physically placed on. On his version the final rune is only partially written. It symbolizes how close to death anyone can be at any one time. The animal traits have caused any and all hair to fall out of his lower body- even the peach fuzz that normally covers the majority of the human body. His legs turning partially into flippers is not right for a blue whale- if he completely turned there would be nothing there at all... at least visible. A blue whale actually does have remnant leg muscles, but nothing really attached to them anymore- they had four limbs aeons ago, but they had long since been evolved away. Unlike most other species, the phallus of this colossus is actually the same dark blue-grey the rest of its body is. Because it is fully transformed by default on Orwell- it is the only dark blue flesh he has that completely lacks interference with his default peach flesh. His tail is so huge in his current state that it takes up the entire remaining length of the room and the fin is propped up on the opposite wall. His dork is even beyond that- now that his hips are larger to allow for a greater size his phallus itself has grown and it arches up, touches the roof, bends back down and the very tip is wedged sideways against the wall above his head! The very base of his cock is as thick as Tiff's midriff! His balls are held firmly to his body in a taught, ultra-smooth scrotum, and each orb the size of a yoga ball. He lifts his tail slightly at the base over and over, which bobs his giant nuts, and causes the very tip of his penis to rub against the wall. Precum oozes down the wall in a constant trail. It is almost sample collection time, so she might as well just collect now; she has a harvet orb in her pocket.

Tiff strips naked entirely and Orwell watches silently. He wanted to just do this himself seeing how nervous she was- understandably intimidated as hell at the size of a phallus three times as big as she is. He was considerably less against the idea seeing her strip for him. Tiff seemed like the poster girl for a classic blond- obviously not dumb since she is Adel's assistant, but a bit of a clutz, busty and pretty, and generally quick to arouse. She hugged the base of his shaft, shivering again at the contrast of temperature. His cock felt so hot against her like it could almost burn her! She wedged the shaft between her large tits and could feel his heart beat inside of it, thundering against her own body- her own heart almost synchronizing with it. She shoved forward as far as she could, causing the end of his shaft to bend even further against the wall. She carefully climbed up, her body now holding it down enough that she could shimmy her way further up the shaft! It was like trying to climb a smooth tree! She looked down at him, giggling at the absurdity of the situation- both nervous as hell and aroused as fuck. She was at the mid-point of his cock, her back against the ceiling, looking down at him on the bed, being held up- easily- by his dick alone. She dropped the orb down for him to catch and place on the tip of his dick- since he is the only one who can reach it. Of course the orb is like a speck in comparison- he only needed it to cover the urethral opening to catch the stream, but he waited for now. It would need all the room it has to contain his cum, never mind his pre- they were going to see if it's possible to annihilate a havet orb with liquid pressure. When his cock throbbed, it pressed harder against her chest and caused her to exhale slightly, by squeezing her against the roof! Her tits wobbling at the top, her arms were down toward her sides, pushing a lower section of the shaft as hard against her bare clit as possible, grinding her hot box against him. Her legs are bend slightly trying to pinch him with her thighs while hooking her feet on the lowest portion and giving him a backward foot-job.

Orwell groaned- his voice so loud it could be mistaken for distant thunder, though he still does not speak any actual words. He bucks his hips and the jets of precum increase in strength, causing them to splash out across more of the wall, as if trying to paint the entire wall in his juices.

Tiff spoke sweet nothings between constantly kissing his shaft with her plump scarlet lips. "That is it big guy, use me~ squish me! Crush me under the weight of COCK! It is all I can smell, all I can see... all over me, burry me in it!"

Even Tiff's movements became frantic; love-drunk off his musk and the concept of being completely conquered by a cock many times her size. Neither of them noticed his balls growing slowly during the entire thing. The scrotum holds them rather firmly, so their weight is not really noticeable without him standing up- and his legs currently won't even allow him to stand even if he tried. Quiet gurgling could be heard from the huge spheres as they swelled larger and fuller. Like the fruit of his masculinity- plump and juicy, ready to be harvested. Each ball is larger than Tiff's entire torso! Like a beanbag chair that was overstuffed to the point it became spherical. Those are so big that even when his animal traits revert, he will only be able to fit through the door by walking sideways. Only one nut is going to fit through the doorway at a time, and even then- just barely. Orwell thrust up against her, hearing her exhale sharply every time his dick ground her against the roof, watching her tits wobble around on either side of his cock and her own hips grinding into it to get herself off too. He liked that part the most. Reducing her to a trembling, moist, desperately horny little thing in the shadow of his immense dong. Finally reaching his peak, he remembered at the last second to cap his phallus with the little havet sphere and then arched his body in pleasure. The end of his cock bent against the wall over his head so hard the drywall started to crack!

He erupted cum at such a high pressure he was sure the orb would fly off the end and not catch anything, but against all odds it held fast, and exploded in size! The cum balloon swelled to the size of a medicine ball on the first blast alone, then a yoga ball... then the size of a giant faire pumpkin, then to the size of the bed before tapering off! If it wasn't as hard as stone from internal pressure, you'd be able to use the cum sphere as a water bed! It is taller than Tiff is- no one can lift that, it has to be rolled to get it anywhere! It won't even fit through the doorway- Adel has to use a teleportation spell to get it into her lab! Tiff is almost more tired from the experience than Orwell, and just remains on top of him as his dick slowly shrinks away and compacts and the two of them just nap there till dinner. His animal traits slowly melt off him as they rest, till he is once again just a normal man with whale genitals and a whale tail sized down for his human body.

Dan remained in his room after releasing his own latest blast and lost track of time in a book; actually reading it this time. Rael knocked on his door, startling him out of his read.

She leaned into his doorway a bit timid and already blushing. "Heeeyy~ soooo, I was wondering if... uhm." She sighed and pouted a bit. "I don't know how to word this without sounding like a complete slut. You have... animal parts and I was just... do you... like me? I was wondering if you wanted to have a little fun on the side."

He quickly put the book down and raised a brow. "On the side?"

"Blowjob? I just want to... I don't want to blow a dog, right? But like, you're not a dog, but have dog parts... so I could experience... y'know?" She looked a little desperate- hoping he understands without thinking she is a weirdo.

Dan of course agreed. Rael pulled her top off first, no bra on under it. Her breasts are jiggly little B cup mounds, and both her nipples pierced with a gold ring. Rael once again crawled up onto his bed and undid his pants, smiling at the larger size of his balls now. Each one the size of a honeydew melon- which is massive considering he is part canine, which generally have balls no larger than a default human. He had just cum two hours earlier by himself, but Rael was damn hot, so Dan was sure his new enhanced nuts could manage another go. She hooked her fingers in the rings on her nipples and used them to jiggle her tits for him, while rubbing her bubble butt on his thighs sitting on his legs, watching as his shaft emerged from its furry home. She placed an index in the divot on the end of his penis so the urethra rubbed on the underside of her finger and she rocked the shaft back and forth feeling it push up further against her touch and harden. His balls felt so warm. They very slowly increased in size a tiny bit. His dick is sort of shaped like a baseball bat- it gets a bit thicker the further up you go.

Rael seemed to stare at it for a few seconds before quickly kissing the very tip and then sliding her dark lips down over the whole thing right till the fur of his sheath tickled her lips! He immediately noticed yet another piercing she has- two ball bearing piercings on her tongue! She also has two thin chains on her ears linking a piercing on the top and bottom of both, two spike piercings on her left brow, and a small septum ring. She used the ball bearings on her tongue to massage his dick, one metal orb on either side of the urethral bulge. Her hair is raven black with a blue streak dyed in it, and pools on his lap as she bobs her head on him, though he can see the glint of her dark blue eyes as she makes eye contact the whole time through the gaps in her hair. Her eyes are a shade of dark blue that make them almost look like a tone of purple, like indigo. She hums as she sucks him and tastes his pre, like someone enjoying a good meal. She squirms a bit to set her legs further apart and back so she can suck him without needing to hold herself up with her hands, and then uses them to immediately cup his balls and roll them gently in the sack. His scrotum so silky soft, but also covered in soft fur, making them very pettable. They tightened, threatening to pull themselves out of her hands for a moment and then swelled up noticeably, causing their weight to rock back forward to sit firmly in her warm hands again. She gently scratched them with her long painted-black nails teasingly. Once his knot popped out and swelled to full size she quickly took that into her mouth too- closing her lips tightly around the lower curve to tug up on it. The knot when fully engorged is the size of both of the canine's balls put together... well, both balls before they were affected by the fertility potion- it is definitely nowhere near their current size or he wouldn't be able to fit it into anything. Rael sensed he was getting close already- the pre starting to flow almost constantly and the shaft throbbing quickly and hard, so she eased off and slowly released it from her mouth.

She kissed his balls several times, pressing the soft furry flesh against her face, like a guy motorboating a pair of tits. She then smiled, looked into his eyes and collected all the loose flesh into her hand and closed it tightly. Her right hand was completely filled with empty scrotum, but this pulled the rest of it tight around his balls and also tugged his sheath down- tightening both at the same time with the grip of only one hand. She gently shook it, watching his balls bob back and forth. When his scrotum is stretched around his balls this firmly you can actually see his skin faintly through the fur- blushing pink. She gently started to pull away from his crotch, pulling the flesh even tighter! His sheath tugged down, but the shaft throbbed up. She gently kissed the shaft, but did not grab it at the risk of setting him over the edge immediately.

"Thank you for this~ don't tell the others though. This can just be our little secret, 'kay?" Dan just nodded. "Good boy." Dan moaned, feeling a bit odd- a tingly heat. "Very. Good. Boy. Boiling a big hot load for me? Thata boy- thick and heavy! I want to know what such a big boy tastes like."

Her telling him he is a good boy caused his tail bone to twitch rapidly- his tail trying to wag but trapped under his weight. His fingers and toes tingled faintly. Neither of them noticed his toenails turning to claws like his fingernails already were from earlier. Fat deposits gathered on the bottom of his feet and inside of his hands, creating shallow bubbles as the skin over them darkened to grey-pink, slowly turning into paw pads! A sparse coating of fur started to grow on his toes and fingers! Rael slowly lowered her head onto his shaft and the moment her lips pinched down on the underside of his knot and pulled back again, he exploded. Dan reflexively curled over and put his hands on the back of her head, holding her in place without even thinking about it. He could hear her gulping the cum loudly over and over; she had to swallow after every blast, because it only took one stream to completely fill her mouth- she either swallowed or it burst out all over them both. His tail finally yanked its own way out and wagged between his legs, no longer containable. His ears started to become pointed, and a few strands of fur started to peek out before regressing. Then all his dog features slowly reversed as his orgasm tapered off- leaving him with just the genitals and tail again.

Rael gasped for breath as he finished, then lurched forward and cupped both hands over her mouth with a shocked look on her face.

Dan looked at her concerned. "A-are you okay?!"

She just nodded, slowly taking her hands away. "Y-yea *gulp* I... I just... oouhh-!" She let out a large belch and clapped a hand over her mouth again, bending forward for a moment before straightening slowly and taking her hand away again. "So... SO full. My stomach feels like a water balloon, oh my god, so much cummmm." She groaned, holding her slightly distended belly. "It almost hurts to bend my torso. Oh Gods, I better get going, I need to lay down and digest some of this." She paused in the doorway flashing him a smile and a wink. "Thanks though- you taste great."

Dan did not need to clean up, since she managed to drink it all, so he returned to reading. He is still a bit worried how big he might get, but if he has beautiful women like Rael to milk him empty- maybe he doesn't care as much as he thought he would. His stay so far has definitely been a good bit more pleasurable than he was ever expecting when he signed up. He glanced past the book at his balls though... they grew again during all that. And that part doesn't revert. Each testicle is almost as big as a basketball now- he is going to have to start walking with his balls bouncing back and forth against his thighs like everyone else. He should still be able to wear stretchy pants, as long as he is careful pulling them on and off. The bulge would be obscene but at least he can still cover them- no one else in the mansion can.

About a half hour later another knock came to his door, and Lauren peeked in, adjusting the rectangular glasses on her nose. "Ah~ Dan, it is time to take your daily sample."

His eyes went wide. Wait, what? Rael already... oh. Right, she drank it- that isn't taking a sample.

"Uuuh, about that..."

"Hmm? Rather do it yourself?"

"N-no, it is just that I uh... sort of forgot about that part and already blew, like, a half hour ago."

"Oh- that is fine, the human refractory period is only fifteen minutes. But, this is a good time to bring up- we are sort of short-staffed." She stepped fully inside holding a large bag of assorted items. "The four of us were fine the first two days but as the... uh, capacity of the males increase so do their needs, on top of maintaining the cleanliness of the house and preparing meals, we can't tend to all of the subjects. So, Tiff is being assigned permanently to Orwell, Lucy has already sort of been permanently assigned to Norman, I will tend to Lance, and Rael now has to deal with cooking and maintenance solo."

"Sooo... me, Clyde, and Peirce?"

"Clyde and Peirce are- uh... taken care of." She blushed. "That leaves you, but Dr. Hemlock has prepared a 'toy' for you to entertain yourself with."

Lauren set the bag down and took out a fairly large silicon rubber dildo- a dog dildo with a rather impressive knot and a suction cupped base.

Dan quickly put his book down and sat up straight, furrowing his brow. "I am not into that!"

Lauren looked at it and then back at him like she was puzzled by his reaction. "What, the shape? You won't be looking at it when you use it, so that hardly matters- it is functionality of aesthetics. Here, let me show you something."

She unbuttoned her blazer and suddenly it looked like her tits doubled in size- her outfit was apparently incredibly tight. She then unbuttoned the white top below and clicked her bra open, letting her E cup melons flop out into the open. Her areola are dark, and her nipples completely hidden inside- inverted. She knelt down and pressed her tits into him, then continued to press harder, forcing him to lean back on the bed. She climbed over him and looked him in the face.

"What do you think would compel me to take out my breasts to a person I barely know anything about?"

"I... uh, I don't- don't know."

She spoke in a breathy voice- a loud whisper, and brought her face so close to his; their combined breath was fogging her glasses. "Maybe a better question is what would stop me from doing that?" He shook his head, still not knowing how to answer. "Society builds a lot of rules, but every person is an individual- you cannot build a different set of rules for every single person who is born, so the etiquette and laws are just generic and don't always make sense for the person or situation. But many people like things predictable- it makes them feel safe, so they teach the concept of 'normalcy' and cloud your conscious mind with rules it never actually needed to follow."

Lauren climbed down his body and then bit his pants! She yanked his pants down and then his underpants using her teeth! She then pulled both further down with a hand, while rolling him over with the other so he was ass-up! She smiled and chuckled in her deep womanly voice as she seen his bushy tail stand erect.

Lauren ran her hand lightly over the tail. "Animals other than humans rely on instinct, preventing their conscious mind from fully reaching its potential. Your dog features are relegated to your unconscious mind- which means this tail bypasses the concepts society poisoned you with. It doesn't care what anyone else thinks- it only responds to how YOU feel. So... let's listen to the tail."

She gently grabbed up some of the loose scrotum and pulled back- popping his balls out behind and aiming his penis straight down, pressed into the bed. Lauren ran a single finger up and down the shaft and smiled as his tail twitched. She could tell he was deliberately trying to hold it still out of embarrassment, but the tail wasn't having it. She kissed his shaft softly several times.

"Pleasuring the shaft- traditional, predictable. It feels good- it works."

She moved her hands up and cupped his large balls, rolling them around and kneading the soft furry skin of the scrotum. "Mmm, but what of these now? The feeling of their weight is such a burden~ but comforting, no?" His tail started to wag more. "So juicy, so full. And they have been growing- ripening, getting even more impressive, even more productive! This is where the climactic mess comes from and the love-drunk drive for more!"

Her hands raised, feeling the looser scrotum at the top, then his swollen, stiff taint, then over his butt cheeks. She paused a moment and placed a single finger on his anus. "Oh, but what about this? This is tender skin too- so many nerves to play with, such a naughty place." His tail wagged erratically- she could tell he was trying to influence it again. Lauren slowly pushed into his butt. "Oh, but do you feel that? No, not my finger, the other thing."

His tail started to wag quite energetically, and Dan unintentionally let out a stifled moan, pushing his head into the pillow to silence himself. Through the anus she can get directly to his prostate through the relatively thin wall of his colon- and cut straight to the source. It is bigger than normal too, so she has no trouble finding it even with only one finger in him. She used her other hand to gently masturbate his dick. She nudged his prostate and felt it wobble and fill up. She pushed against it and after a moment, felt it pushing back against her finger! Dan groaned, feeling warm and suddenly hornier than he was only moments before. She pushed harder into it, and it pushed harder back, engorging even larger! Dan suddenly felt pent up in spite of having just cum less than an hour ago! He tried to squirm away, still not sure about this but she pinned his hips to the bed, so trying to squirm away only ground his dick into the bed under him harder! Lauren pulled her finger back out, and the movement caused another pleasure jolt. He gasped at the jolt but then moaned as he felt an internal pressure in his nuts! They let out a quiet, muffled gurgle and started to grow AGAIN! He felt so full! They were so warm and full, their weight and size growing even more. Lauren chuckled as his body shivered from the pleasure- he was afraid to move at risk of setting himself off. Lauren leaned forward, kissing his butt before sticking her tongue inside! With no way to move his hips any further forward, he stupidly moved them backwards on reflex which only caused her to go deeper and he moaned loudly and climaxed! He got up onto his hands and knees as he came, looking down at the mess he was going to make but seen the orb on the end of his dick! He did not even feel her put it there! Starting at the size of a golf ball, then to a softball, cantaloupe, basketball, medicine ball, then beach ball! That is so much larger than the other day- and he had cum once already an hour earlier this time. How big would the sphere have gotten had Rael not already milked him?!

Lauren smacked the side of the sphere to knock it out from under him so he could flop back fully onto the bed as she stood fully. "In any case- you can just not use it. It is just there if you want, since we can't be. That is only one part of your toy anyway."

"H-huh?" He turned his head to look at her, but remained fully laying down.

She took out a metal arm with a complex brace on either end, then a clockwork mechanism, then two rubber rings linked together with another mechanism? She took the canine dildo and hooked the brace on one end to the suction cup around its base, then hooked the rings to the opposite end, then assembled the clockwork mechanism to the middle of the metal arm- which Dan now noticed is some sort of piston.

Lauren pointed to the rubber rings. "They are elastic, but very tight- pop one behind your knot and the other in front. Well, put the dildo in first, then the rings at the front over your dick... probably easier to do this before it is fully erect." She held up a clockwork key. "Then charge the engine and let it go."

One side works his cock, the other side penetrates him- when one side pulls out the other pushes in, and it goes back and forth working him from either side. Lauren left the clockwork sex toy with him and left him to rest. Now he needed to nap till dinner- after being worked over by two women in one afternoon he was absolutely spent. And dehydrated, which didn't help.

He was groggy still when he woke up for dinner, but was hungry as hell so his stomach dragged him out of bed. Dan walked slow, not used to his nuts bouncing around so much when he moves. They grew when he was with Lauren too- forcing them to action twice in such a small window of time would have instigated it. He did not want to risk hurting them trying to stuff them into too-small pants, so like the others guys he left his room with just a shirt- pants don't work anymore. He sure hopes it is reversible, because leaving the mansion without pants is going to be real awkward, although his love life might be more active as a result. Honestly he was considering approaching Rael once this was all done. On one hand she is a researcher and he is a test subject so of course she was being all sexy to him and getting him off. On the other hand... she wasn't gathering a test sample, she did that last one just for herself. Unfortunately now she was on kitchen duty, so Dan either got himself off the old fashioned way, or he tried out Adel's homebrew mechanical sex toy.

As Dan was walking up the hall from his room to the banquette hall, he seen Lucy leave Norman's room, but then a moment later the door opened again and a fully naked Norman went to step out, but paused in the doorway.

"W-wait I can... I can do it."

Lucy turned to him look a bit worried. "Wait, no, just stay there!"

"I am not... that big... am I?"

He lurched forward then bounced back. Dan furrowed his brows, trying not to stare- but still definitely looking as he walked past. Once he passed the open door he immediately paused and his heart jumped in his chest at the sight. Norman could not get through the door- his testicles were caught on the doorframe! Each testicle was taller than he is while fully resting on the floor- he could not fit EITHER of those through the door, even one at a time. He looked delirious, and his penis was bobbing up and down like it was trying to agree with someone. It drooled pre steadily and spat a blob of it with every pulse. The veins on the base of his shaft were extremely thick and visibly pulsed a fraction of a second before the shaft itself did. He attempted several times to walk forward, stretching scrotum and then getting slingshot back by its elasticity. Everyone but him seemed to realize he clearly could not fit through the door. No wonder no one seen him in the mansion for a bit- he literally cannot leave his room. Lucy tried to convince him to stay in his room and hurried back over to him to try and just push him back in, since he was too horny and out of it to get the picture.

There was a dull thud and he groaned, and Lucy immediately took a step back. Uh oh. The thud was his balls on the other side of the wall! Then another thud and the sound of creaking wood! Norman was literally dragged backwards by his own balls! They are grinding against the doorframe, threatening to shatter it- and the testicles tensing up got rid of the slack in his balls which yanked him backwards, since the mass of his balls is greater than his entire body! The stream of precum lifted into a lazy arch, and strengthened and became even more consistent as its reach stretched slowly further out into the hall. Now Dan backed up too, considering making a mad dash past him into the banquette hall but not wanting to risk it. Norman's groan went on, getting louder and suddenly his balls relaxed a moment and then slammed up against the wall with a loud bang, jerking his body back against them before his dick exploded a solid stream of white across the hall with enough force to actually splash against the wall and spray out in every direction! His dick could not even buck- the liquid pressure passing through it held it perfectly straight! The first stream alone lasted two seconds before a half second pause and then the second jet, then the third, fourth, fifth... Dan lost count- holding an arm up to shield his eyes from the spray. It took Norman a full ten minutes to completely stop blasting out cum, and he practically passed out leaned back on a wall of his own scrotal flesh. Even then, the pre seemed to start to drip again... like he was still aroused- still ready for another go immediately after.

Lucy smiled timidly at Dan, gently shoving Norman back to get him into his room. "S-sorry. I will clean this up, er... maybe I can get Rael to do it. I need to take care of Norman. He is kind of, uh... needy, now."

Dan did a bit of a running start and jumped over most of the giant puddle in the hall. At least since cum is so thick it doesn't spread out on a surface nearly as quick as other liquids. Seeing that renewed Dan's fears of his own changes. Was that expected results?! Maybe it wouldn't affect animal genitals the same as human. Maybe having a dog cock will actually save him from the worst of it. Those balls were impossibly giant. If they cannot reverse the process... Norman will basically have been reduced to a living cum factory. If everyone gets close to that size, Adel will need to demolish the building to even get them out again, because no one will be able to use the doors.

At dinner time, Lance managed to get to the table without Dan the others noticing his balls had yet again grown and were now so large that he has to hold up the looser scrotal flesh when he walks, or his balls will drag on the floor. That is not the only thing about him that changed either; his legs are twice as thick as before and end in elephantine stump-like feet, and the skin has turned to grey on the lower leg, fading back to his bronze human tone at the thigh, and his entire body has increased in size a bit, forcing him to duck to get through doors. It also meant his balls are actually a LOT bigger- because they grew in comparison to his body, which also itself grew, so technically they grew twice. Wearing a bed sheet around his hips at this point would only cover half his limp dick and basically nothing on his balls, so he did not even bother anymore.

The reason he got to his chair without anyone else noticing is because Clyde came into the room at the same time... leading a pig. All four attendants immediately freaked out and ran over, but it was Lauren who spoke up first.

"I told you not to tease him!"

Clyde blushed bright red with a bit of an angry look, crossing his arms. "I didn't think... he... it changed the rest of the way when he was- y'know. Because he can't stop blowing for like twenty minutes."

Lauren looked Clyde up and down too- he is a victim of his own teasing too. From the hip down his legs are entirely equine, fur and all- apparently his fur is golden brown. Dan would have guessed it to be black like his hair color, but a horse has both hair and fur- and they can be two different colors. On Clyde's hands, his middle fingers are almost three times the size of all the others, and the nail has evolved into a mini hoof capping its end! Though stretched out because of his middle finger- he does still have hands and his other digits. He also seems a lot... veinier. His muscles tensed up pushing the veins tighter through the surface skin, and the veins swelled fatter in anticipation of more changes that haven't actually happened yet. From what the others can gather from overhearing Clyde and Lauren bickering is that Clyde found their animal aspect a sort of turn on. Like a sort of bondage to tease his partner with- degrading him in a way that isn't hurtfully demeaning or physically harmful in any way. And apparently said partner was Peirce. That would explain why Lauren said they were already taken care of in spite of having no woman assigned to them- they have been 'milking' each other. So when Clyde seen something bringing out the animal in Peirce, instead of avoiding it, he leaned into it. He assumed he could always rein it in after, but as Peirce became more animal his orgasms became longer and longer- neither could fight the animal aspect while in orgasm, so the transformation ended up going the rest of the way before Peirce was able to stop cumming again!

As a feral pig, Peirce seemed to be a bit smaller than his human self, though it was hard to tell since his proportions are completely different as a pig too. His limbs are very short and plump and his body thick and torso longer than it was before. His eyes are noticeably still human, so it appears his mind is still that of a human in there. Like everyone; their balls had increased in size. Clyde's heavy ebon nuts were each the size of a big Halloween pumpkin. Peirce on the other hand... well, pigs have very large balls even by default. Either testicle dragged on the ground behind him since his limbs are so short now- either ball the size of the entire rest of his body. He needed help on the marble floor of the banquette hall because his little hooves could not get enough traction on the marble tiles to drag his giant nuts, so as soon as he entered the banquette hall his limbs started to skitter frantically without him actually moving anywhere- anchored by his own enormous pink balls.

Clyde huffed, sounding like a horse snorting. "I thought Adel used inhibitors that would prevent us from fully turning anyway."

Lauren growled. "Well it did inhibit the rest of the transformation till you deliberately fucked it up! His mind is still human at least. I have some ward rings, come on, bring him up to the master bedroom- I will reverse this." She glanced at his legs then back to his face. "And you."

Tiff grabbed her sleeve stopping her from going and motioned with a slight nod toward Lance. "Actually you better let me; your man seems like he is slipping too."

They both looked at Lance who himself was rather distracted- eating with a spaced out look on his face and his breathing notably labored in spite of him just sitting there. His balls were so full it was making it hard to think. He had managed to fight off arousing thoughts so his penis was still fully flaccid, but leaking pre constantly around the outer curve of his balls because his tanks are still at capacity. Because his body needs release but he himself fought off the horny thoughts- it resulted in his mind simply not thinking about anything, at all. And the absence of conscious thoughts is causing his animal aspect to come out, which converted his legs. Even as the women watch though- the nails on his fingers are slowly enlarging and getting abnormally thick, threatening to stretch his fingers too, and start to devolve his arms.

Lauren motioned to Orwell. "What about yours?"

Tiff shook her head. "He is fine... that is just... his default now."

Orwell is normal human other than his tail and junk obviously- what Lauren made note of is the fact that he is unintentionally holding the table up off the floor. The long table in the banquette hall has one extremely long tablecloth across the entire thing, but is actually three identical tables lined up- the section Orwell is sitting at is actually standing three inches higher than the other two because his balls are holding it up in order to fit under it- so two of the four legs aren't touching the floor. Each of his gigantic navy blue balls are almost as big as big as Norman's are, which means he might not be able to get back into his bedroom. Tiff might have to take him to the pool instead and use that as his new bedroom... but that might also trigger his animal aspect to come out.

Clyde used his enhanced muscles to pick Peirce up off the floor entirely since he could not walk upstairs, and then followed Tiff to the master bedroom to have their animal aspects beaten back with help from magic wards. Lauren hovered behind Lance as he ate- though he was too spaced out to even notice. She did not actually speak up till he finished eating and she placed a hand on his shoulder- it felt so dainty and small now that his entire size increased. She whispered into his ear to help him with his trouble and with a grunt he agreed and they headed back to his room. He had to carry his nuts in front of him by the loose scrotal flesh, but even then had to change which arm he used to hold them up twice before getting to his bedroom because his balls are so heavy they wear out his arms.

"You just took a sample not that long before dinner..."

Lauren sighed, closing the door behind them. "Right... I know. But, your endowments are still increasing. They become needier the bigger they get. Their capacity to store increases, but not nearly as fast as their ability to produce- because testicles mostly produce on the spot; the amount they make ahead of time to store is always relatively low."

"But..." He grunt and then sighed, glancing away as he flopped on his bed.

The bed springs groaned in pain- his weight threatening to snap the entire thing in half. Lauren undid her top and tossed it behind her as she squirmed out of her skirt and panties and then started to climb the bed.

"But what?" Once on the bed, she now had to climb his balls. She flopped over their curvature- their size more than able to hold her entire body weight without being hurt in the slightest.

"But if that keeps happening... how long was that? Two hours? Every two hours means I spend... four hours? Every two hours we spend about a half hour emptying me, which works out to roughly four hours every twenty four hours- and I might still be growing. Which means even more time."

Lauren pout, sliding further over the curvature of his balls and pressing her crotch into their underside while she smeared her boobs up the upper curve to grab his fat sheath with her hands. She pressed in on it gently and rolled the fat, rubbery, hot folds of his sheath back and forth; coaxing his dick out.

"But it feels good? Can you really consider time spent on pleasure as wasted?"

He just grunt in reply, not really having a counter point to that. Lauren noticed his fingers were quite thick now. She needed to get him off to fully restore his concentration. Even if he doesn't automatically explode from lack of room for more cum- he will turn into a feral elephant if he doesn't get off soon. And an elephant is bigger than the entire room; he would demolish the building. The banquette hall is the only space in the mansion that could fit a bull elephant.

His penis started to unravel, rising up to meet her as the skin folds smoothed out and then the skin tensed up, pulling taut from internal pressure- the tightness a direct measure of arousal. The skin pulling smooth and shiny, the throbs as it tries to swell still bigger only to be restrained by the elasticity of the skin- these things were universally hot, because they are visual representations of arousal and pleasure. And having felt such pleasure herself; Lauren's own body tingled from watching it, because it triggers her own memories of such feelings- this is known as sympathetic pleasure. The scrotum and base of the sheath has a rather leathery texture to it, and slightly craggy flesh- but the actual phallus is perfectly smooth and shiny once in full glory. The entire shaft is blotchy- pink and grey. From the side it appears to end in a blunt tip- like their limbs, it is just shaped like a cylinder. From the front of the phallus you can see that it has a projected rim which is effectively its glans, and then a slightly impacted front where the urethral opening is. Unlike most beasts- the urethral opening is not just a little tube or slit opening; the opening is actually shaped like a Y. The phallus is actually not that much longer than a very large horse's endowments, but is MUCH thicker. Easily as big around as a fire hydrant, and able to move around like an arm, capable of wrapping around or even picking up objects.

Lauren place her entire face into the indent of the front of the cock, cupping either side of the shaft with her hands- needing both hands to wrap fully around it at any point. His balls occasionally made a quiet churning sound or slightly gurgle- the heat they give off is immense. Elephants have internal testicles normally, but Lance's family jewels are external still for the same reason Orwell's are. Lauren had to spread her legs to loosely grip his balls with them, because her weight is wedged in the scrotum strung between either ball- so when they start to churn they rock her entire body along with them. His fingers continue to thicken, and his palms billow out swollen looking. His skin starts to turn grey and his entire arms start to widen! Though she does not outwardly show it, Lauren is getting nervous herself at how far he will turn if she doesn't get him off soon. If his body increases in size any more the bed will explode out from under them. She flips her body around, sitting on his face while still rolling her face against the end of his dick, lapping up any of his salty lube- now using her bare feet to rub his balls. She can feel him push his face into her pussy to eat her out, but pushes further up than should be possible! Uh oh, his face is changing! The bridge of his nose pops as it grows in size, and the bridge starts to project out from his face in an arch as the bottom starts to divide from his face entirely! He is growing a trunk! This allows him to wedge his nose right into her plump labia, and then actually penetrate her with the end of it- filling his lungs with her scent. He lifted her labia up with his nose which allowed him access directly to her exposed clit with his mouth, kissing it.

Because his phallus is so large, the havet orb she has to use on him is already the size of a soccer ball before she even puts it on. Because he was so full and needy it does not take long to get him off at all and he cums for as much time as it took to get him to reach that point. By the time he stops the sphere of contained cum is slightly larger than the bed! Adel uses teleportation spells to move it. Lauren sighs as she slides off and Lance falls asleep for a bit. Though quite slow- his animal features are regressing. Lauren makes sure to watch him long enough to confirm they are in regression. His hands were nearly stumps, you could only externally see his digits as mere bumps on the ends of his swollen arms, but their shape was re-emerging now. His face already had a trunk- though it was more like the snout of an ant-eater since it was only a foot long at best. They all have less and less time to do other things- she will likely need to tend to him again in another two and a half hours or so... any longer than that and they risk him starting to turn more beast again- or best case scenario he just erupts into orgasm automatically because his body can't hold it anymore and makes a hell of a mess. At this point if they don't use a havet orb to contain it they risk causing flood damage to the building from the sheer volume of fluid. And given how large Norman became... Lance's elephantine balls were naturally larger by default... so he more than likely still has a ways to grow. And the time between needing to empty again is only going to shrink. That is why the women cannot afford to try and tend several men each like they had been- leaving their man for too long risks a cum explosion.

Dan did his best to ignore his own needs the rest of that day. He had already gone off three times in the first half of the day that he deliberately avoided touching himself as long as possible in the second half. By dinner he was already feeling horny. He could not properly wear pants and he could not put his dick away, so that meant he could not use the entertainment room or anyone else passing through will see his raging boner immediately. Reading in his room became increasingly difficult as well, just because his concentration kept faltering. When anything involving a woman arose in the book he is reading he would imagine what they look like and then space out unintentionally thinking about how good they must look, what they look like minus the clothing, what they would look like riding his cock. His balls are so heavy it is impossible to ignore the feeling of them rolling up and down in the scrotum slowly, slightly off-rhythm with one another. By now even his knot had popped out of his sheath in spite of not touching himself once. Dan started to squirm in bed, groaning as he tries desperately to just pay attention to the book. He could feel hot pre collecting in his belly button and overflowing off his side. No, just ignore it- paying attention to it will only arouse him even more. A quiet gurgle, a pulse of heat, churning sounds muffled through the skin, a slight pulse of gentle pressure. Dan could feel them growing a bit more, getting larger... stronger, needier- more demanding, and their demands heard louder through his body.

By the time he dropped the book to look down to see how much bigger his balls had gotten, he gasped at the sight of his cock- it looked almost like it was going to explode in a more literal sense. Not only were his balls even larger- eclipsing his thighs while perched on top of them- his penis actually looked slightly larger... or at least painfully hard. The knot was swollen bigger than he had seen it before and the entire phallus had darkened to an angry shade of red- making the millions of tiny veins webbing its surface look black in contrast! The veins themselves bulged out overly fat, but because they are so small and numerous on a canine phallus; it made the entire surface of his cock sort of lumpy. His dick bucked so hard when it throbbed that it looked like it was trying to lasso something with the strands of pre. His balls no longer moved- they were wedged against his crotch and would not budge. Dan gently brought his hand down, almost afraid of how it would feel, since his dick looked like it was at critical mass. It started to vibrate at the mere touch of his fingers and the moment he actually gripped it; he exploded! He did not even need to stroke it even once- just grabbing it was enough. The stream of cum was so strong it bypassed his body and splashed against the wall over his bed! Each throb, his balls grew a tiny bit bigger, extending his orgasm even as he was having it! By the time he stopped this time each testicle was the size of a yoga ball, or large beach ball. It felt so heavy, but so good. When would it end though? Would it end? What if the potion was far too effective? Even when he was not getting off, he was thinking about getting off, or at least thinking of his junk. The memory of getting off. The pleasure, wanting the pleasure, remembering the pleasure. The other aspects of his life slowly becoming more and more muted as his sexual needs kept increasing, demanding more attention. His balls slowly matching him in size and authority- at this rate they will overcome him both in size and dominance. His balls will dictate what he does.

By the time the night was through, he was feeling horny yet again. He wanted to ignore it- the faster he caves in the more he promotes the changes and the faster he NEEDS to give in. But at the same time- look what happened the last time. He exploded before he could grab an orb to contain the mess in. And how much control is he really going to have in his sleep? One sexy dream and he cums into his mattress so hard he blows a hole through it like a pressure washer. He wasn't that full now but... he did not want to wake up halfway through the night when he is. With a long groan he grabs the toy Lauren left him, though detaches just the dildo part for now. He starts with simple masturbation, resting the dildo between his legs on the bed, and as he works himself up he brings his leg up- tapping the suction cup on the bottom of the dildo to press the tip in using his foot. Even though he was not that built up; Dan still erupts quickly using the dildo as a little extra help. This time he contains it in a ball and the sphere bloats up to the size of a yoga ball by the time he stops, so he rolls it into the corner to get rid of later and goes to sleep.

The next day he barely gets through breakfast before his dick starts peeking again, and occasionally letting out a drop of pre. None of the other guys were there at breakfast, which was a little worrying. Did they have breakfast before him? After him? Or were they all now so large that they cannot even move to go get breakfast in the first place? Walking was hard now, their weight pulled his hips forward so when he started walking it was sort of hard to stop- but at the same time strained his legs more because his thighs had to roll each testicle out of the way in order for his leg to move forward. But... the weight also felt good. It felt good rolling them around, tugging at his crotch. The weight was oddly comforting, which caused his arousal to go up faster. So even trying to move around only sped up his pleasure.

This when he returned to his room he hooked up the full toy to try out. The rings were hard to get on- the ring at the base needed to go behind his knot but it is very tight so he had to thrust hard to get it to pop around, and then the moment it tightened around the other side of the knot it caused him to shiver from pleasure, and his knot to flare in size, making it fit even tighter! The other rubber ring was spaced apart just barely far enough from the other to be on the front of his knot- they are close enough together that they are both partially stretched open by his knot on either side. To start the toy he just winds up the device with the clockwork key- to stop it he either waits for the clockwork mechanisms to wind down, or place the clockwork key back into the device without turning it. As soon as he started it, the piston moved forward slowly pushing the dildo into him, then shifted back, moving it out of him. The rings on the front worked his shaft indirectly and his knot directly! When it moves back the front ring gets yanked over his knot, stretching open to fit and hugging the knot tightly, then when it moves forward the front ring pops off and grabs the shaft while the back ring yanks itself open to stretch around the knot! With the dildo working his prostate in the back- the pleasure was so intense, so quickly that Dan could barely even think about it. As soon as the toy started the crumpled into a shuddering, moaning heap on the bed. He kept shifting position around, squirming from the pleasure before settling into being on all fours, so his tail didn't get squashed under him and his cock isn't rubbing on the bed, overstimulating it. The dildo actually rubs past his prostate twice per stroke- once as the tip starts to slide in, but then passes the prostate and the feeling eases a bit and then the knot pops in and abruptly taps the prostate causing a pleasure spike, before it works in reverse and then repeated.

Dan did not even notice himself start to pant as his body temperature rises. His tail wags hard enough to fan his back so evaporate off the sweat as it happens, but his body was still hot. As he pants; his tongue becomes thinner and broader, making it hard to contain in his mouth. Hairs start to sprout slowly on his upper back, slowly forming a sparse carpet of fur. His fingers and toes curl to dig into the bed under him as he moans in pleasure- oblivious to the fact his nails are darkening and turning to claws. It is a good thing Lauren's care package contained a lot of havet spheres. He quickly reached climax and created another ball of cum slightly larger than the one still sitting there from the night before. That felt... SO amazing. Dan was almost disappointed he came so fast, he wanted more time to experience that! When he went to take it off he paused, looking at his still erect penis. The knot had become tiny, but had not popped back into the sheath yet. He obviously did not feel full anymore but... was he completely empty? Maybe he could go again- to make sure he is completely empty. Then he would be able to go longer before the next time, right? Yea, that made sense. Instead of taking the device off, he turned the key a few more times and then pulled it back out- letting the toy come back to life.

As the toy worked him, he felt a slight ache in his balls in gentle pulses but the pleasure around them was enough to entirely distract him from it. The ache quickly faded, and his balls gurgled. His prostate throbbed softly and then his balls started to slowly swell larger! On all fours, he had to start to straighten his legs- his balls pressing into the bed under him too hard. He was so enthralled with the pleasure from the toy that the fact his balls are enlarging did not register at all with him- at least not his conscious mind. Stretching his legs out to give his balls room also had him fail to notice that his feet were stretching beyond what should have been possible. His digits fattened on his feet and hands, and both hands and feet started to stretch longer, devolving toward paws! Fur started to grow on his digits, then the backs of his hands and feet. The fur on his back became thicker and started to spread down, trying to connect with his tail. His balls continued to grow, now pushing into the bed even with his legs fully extended to lift his lower half as far as he could! His balls lifted his hips and he shuddered in pleasure- his animal aspect aroused by it- his human aspect oblivious to it. He lifted his legs entirely and bent them at either side to cradle his balls with them while his nuts carried the weight of his lower half on their own. When he climaxed this time, the sphere of spunk created this time was considerably LARGER than the last one in spite of having been made immediately after it! He just let it roll off the bed, too tired to actually put it over in the corner. He just flopped onto his side and let the machine work him over in the afterglow of orgasm.

Dan was barely aware of how much time passed with the machine still going- he wanted to ride out the afterglow, but started to unconsciously gently thrust his hips a bit. His balls gurgled and started to fill again! The machine was working him up again right after his second orgasm. Without thinking of the consequences at all, Dan started to fantasize of sexy things again and just let the machine work him over a third time! He left it running too long after the second orgasm- he was horny again! Even without his body weight on top of them, his balls started to sink lower into the mattress from the increase of weight! He placed his front paws on them and hugged them with his legs from below- still not noticing that his feet and hands were now fully transformed into dog paws! His teeth started to sharpen into fangs, and his ears became pointed and started to grow fur on the back! His lips turned glossy black as he continued to pant; now more labored. Even though it did not affect his pleasure at all; Dan started to thrust his hips automatically, like he was fucking some phantom lover. Since the toy is attached to his butt and genitals it did not matter what angle or position he put himself in- the toy follows. There was a quiet *gloop* sound almost like a bubble in a water cooler from his balls before they made a muffled squelching sound as they tried to make more cum than they can contain. His balls started to grow even a bit larger still! It was hard for him to tell the difference by appearance even if he was fully paying attention. Once they get big enough it is hard to tell when they get bigger again, because there is less and less objects to compare them to. You can't tell if something is bigger or smaller if there is nothing to compare it against. When he came a third time, the sphere was exactly the same size as the last one, in spite of him just having climaxed three times in a row. His long orgasmic moan became slightly distorted. The fur starting to grow on the back of his neck, and his neck undulated a bit and grew slightly longer. Dan immediately passed out after the third orgasm- the machine still working him for a bit, but since he is unconscious it was not able to work him up again, and the clockwork mechanism ran out charge not too long after without him to wind it up again.

He woke up around noon, feeling pent up already beyond expectations. Rather than empty him out so much that he cannot cum again for a long time- having so many orgasms in a row only forced his body to increase his capacity faster. Now he needs to cum just as often, if not even more frequently now! His fur regressed quite a bit and all changes on his neck and head are regressed when he wakes up but he still has four paws. He is aware of it, but what it actually means for his body does not register- he is groggy, horny, and needs to go to the bathroom, so those all took priority. He also did not notice all three cum spheres were missing from his room. Adel is still monitoring everything from her lab- and teleported them out to use as samples while he slept. Dan shambled to the bathroom, having to lean on the wall for help. His balls drag on the floor if he does not hold them up with his hands, and they are very heavy. After he went to the toilet he immediately turned to the sink and drank water for almost ten minutes straight- not realizing he was lapping at the water to get it in his mouth... like a dog. He did not even take the device off from earlier- it was still on him; just inactive because it wasn't wound up. He ate lunch, failing to realize how nervous Rael looked while watching him- and also failing to notice there was cum literally dripping down the stairs on the far side of the banquette hall. You could hear the sounds of heavy breathing, grunts, and the slapping of flesh- Clyde and Peirce upstairs going at it, and blasting so much cum that it overflowed the room, the floor in the hall, and was now trailing down the entire flight of stairs to the banquette hall at the bottom... and they were still going at it. It was a hell of a mess but there wasn't really anything to be done. There was not enough women to take care of them, so they had to let them take care of themselves- this is the result. There was already several giant spheres of cum stacked up beside the bottom of the stairs from them. Several more lined either hallway with bedrooms in them. They were creating new ones faster than Adel could process them.

Immediately after lunch, Dan shuffled back to his room and wound up the machine to empty out again- he was already starting to leak. The rest of the day was a blur; and the next was no better. The pleasure was amazing- he had been leery of the toy at first but now that he has tried it- it is his new favorite thing. The size of the cum balloons he created filled one side of the room while his balls occupied the other with him squashed between them! His balls overflowed the bed, growing larger and larger. Furniture was shoved aside to make room, eventually everything in the room was pushed into the corners to make space. Adel teleported him out of his room, placing him in the banquette hall which had been temporarily shifted around to act as a collective bedroom. The master bedroom had been utterly destroyed- since Clyde and Peirce had been left to use it for themselves for a while. By the time the women had the time to check on them to make sure they were alright- their two sets of balls had grown so monumentally enormous that they filled the entire room and pushed into the wall so hard that it started to explode outward at the doorway! The doorframe was shattered and the drywall crumbling away- testicles bulging out from around the load-bearing beams on the inside of the wall that still managed to hold up long enough to teleport the boys out of the room before they collapsed the entire second floor. The entire mansion smelled of cum- there was no escaping the masculine musk at this point. Giant, smooth, sweaty balls rolling back and forth; all larger than an adult human each- at the very least. The women flinch every time one of the gargantuan balls rolls forward, because you never know when they will erupt. They did their best to contain it into spheres to teleport away, but the orgasms were hard to predict. If they fill completely sometimes they just erupt without anything actually touching them. And the gap between orgasms keeps shrinking while the length of the orgasm keeps growing.

Was that Rael Dan felt petting one of his giant nuts? Someone just walking past? Or another titanic testicle sitting up against him? He can't tell. The entire banquette hall filled with giant sweaty balls, always churning. Ripening, swelling bigger and rounder, fuller and needier. How could anyone hold so much inside of them? It needed to come out, they liked to let it out, and so they keep making more... and more... and more. They had been spaced around the outside of the banquette hall, leaving the middle an area for the women to work with and pile the filled cum balloons for transport, but as their balls continued to grow, and push back against the walls behind them, they were forced to roll further in toward the middle. Balls against balls- there was humans in there too... somewhere. Good luck finding them. Eventually, navigating on the ground level became impossible. To get to the men, the women had to literally climb the giant hot, meaty spheres and then slide down between them. They can grab onto the loose scrotal flesh as hand-holds to scale the outside of the gigantic testicles. And still they grew. Dan and Norman had stopped, but because their default sizes were larger, the others kept going. Clyde, then Peirce, Lance and then shortly after Orwell finally stopped growing. By that point however there was not enough room for them all, even in the giant banquette hall- luckily the roof of the hall goes all the way up to the second floor- there is no first floor roof over the banquette hall... so when they ran out of space on ground level, their balls popped up over one another, and they were lifted to the upper level on an ocean of bulging flesh. Not only were they balls to the walls on the first floor, they were balls on balls stacked on top of each other too, filling all of the vertical space! The center of the house was a gigantic ball pit!

Lucy quickly hustled up to Dr. Hemlock in her lab- soggy with cum soaked into her outfit again. "H-how much longer do you think it will be Dr. Hemlock??"

Adel smiled and tapped an enchanted onyx slate, creating an image across its surface of a gigantic structure that resembled an aircraft hanger. At the middle of the structure is a monolithic glass cylinder with many pipes running from both the top and bottom of it. Along the side are several comfortable looking chairs suspended at level with pillowy, rubber-lined openings. The inside of the cylinder is divided into six equally sized sections. A harvester. The openings are for their phalli- the empty hanger to house their balls, the seats to restrain them in- the men can cum endlessly into the containment cell which then automatically transports and contains their unrelenting supply of cum.

"Already to go! I am going to rely on you girls to gather some, uh... entertaining material to put up on the glass displays in front of the men, to keep them amused. While in a state of nearly unending orgasm I don't think they will have too many active brain cells left to pay much attention so... don't put too much effort into it. They are easily amused."

"And their physical state?"

"Hard locked- now. I let their minds partially regress, and allowed their limbs to devolve into hooves, paws... or, flippers in Orwell's case. It also meant Orwell and Lance are twice their normal size, and Peirce is abnormally muscular, but... we have equilibrium at least. Rather than let it slingshot from one state to another, I increased the threshold of what aspects the tonic was allowed to manifest, so now there is no fluctuations." She took a deep breath, fully turning her chair around to face Lucy. "The problem is that both the transformative tonic and my fertility potion both require mana. They are physical concoctions made from physical materials, but without mana those materials do not exhibit their effects nearly as extremely, or as quickly as they do now."

Lucy nodded. "Which means if you completely cut off the mana to terminate the animal aspect... you'd also kill the effect of your potion. So you couldn't cull one without the other, which would terminate the test."

"Yup. As for the test itself- obviously not done yet. We know it works... VERY well, regardless of species. It also has equal effect regardless of species. The sperm density, quality, volume of ejaculation and even testicle size increase is the same across the board. I mean... their sizes are wildly different, but the size INCREASE is not."

"Doesn't that... cover everything? Doesn't that conclude the test?"

Adel hummed, but shook her head after a moment. "Semen contains calcium and protein- decent protein by volume. Protein is pretty complex, containing quite a few different elements to make a single complete protein. Breaking that down both takes and gives off a good bit of energy... our bodies can use that energy and material in the form of calories- converting it to bioelectricity to operate our body. Energy is energy- electricity is just another energy. We break down their semen in the hanger- converting kilocalories into joules. Constant flow of joules? Wattage. We power the generator on their cum alone."

"Sssoo... the new test phase is how much power can we harvest from... cum?!"

"Yup. Also, semen from a strong stallion or thorough bred dog to inseminate a female with, costs a shit ton of money... and we now have gallons of both. The havet spheres have no air inside of them, so bacteria can neither get in, nor form inside- while it is contained in the sphere it cannot 'spoil', so we can transport and sell it. The excess we do not burn directly as electrical energy? Decomposition of organic matter- yes, those same proteins- creates methane... a highly flammable gas. Burn gas- create energy a different way. It doesn't matter HOW you use it- it is still useful no matter what. Once we measure the degree of all this we can properly measure the utility of the fertility potion- then our testing is done. Potion is ready for marketing, and we have our data to sell it with."

"Isn't that sort of... a completely different test though?"

"Yeaaa... yea. It is, but, look at it like this- to do these additional tests we would need to go through this entire process a second time with more subjects to get there- so it makes a lot more sense to just keep using these subjects who are already in their full capacity state. Besides- they were all pretty desperate for money, and more testing means more money for them, so everyone wins in the end." She tapped a different display showing the main hall of the mansion with a chuckle. "Besides... does it look like they have any complaints right now?"

Lucy laughed too. "I suppose not. Can we really undo everything fully though?"

"100%? Absolutely not. Animal aspect; oh yea, gone, no problem. Fertility? Mmmmm, no. Without the mana feeding it they won't be anywhere even remotely close to THIS. THIS is not physically possible- without the aid of magic you will obviously never get even remotely this productive, it's impossible. But their testicles will still be a good bit bigger than their original size, and they will remain very productive... just... within reason."

Each subject was teleported to their seat at the chamber and hooked up one at a time. The machine milked their cocks- all pointed at one another around the central cylinder that collected their cum. A display slate is placed in front of them to keep them bemused and horny- though that takes very little in their current state. The test would go on for a while yet, but they would each get a fat payment by the end. Maybe Dan could still try to ask Rael out after all this? For now- now that the women no longer had to tend the men constantly- they have access to the world's sexiest ball pit. Not like the guys are going anywhere soon.
