That being said:

This was fucking hard to write. I had intention of turning this into a drama with life lessons, but then suddenly the last chapter happened and threw me for a curve. Thanks to trailstoride for the wonderful assistance he provided for this installment. It was greatly appreciated, and I hope you enjoy reading! (Positive) Feedback is always appreciated!


"D-David?"

...

Shit.

"David...is that you?" Greg asked, partial disbelief in his voice.

I was frozen. I couldn't move from the spot, and the thought of looking at Greg and his reaction to the whole thing paralyzed me. I mean, shit. I just fucked my roommate silly, and made him watch an almost gruesome event of having a tiger turn into a human, who just happened to be his pitiful roommate.

There was an unintended standoff. I was in the worst possible scenario-"Hey!"-I mean, there was no graceful way of get out of here unscathed. I could run, but I was naked, and it'd take time to get clothes on and-"David!"-we live in the same house, which would create its own set of issues-

"Fucking-" I cried out in pain as a large palm struck me in the face. I looked at Greg, who was covering his mouth as if he was shocked by his actions. I didn't even notice when he crawled over here to get my attention, but he had succeeded. Greg looked white, visibly shaken up, but he wasn't running, which was probably a good sign.

"What the hell?" I asked, a bit more angrily than I had intended.

"A-Are you alright? I mean, do we need to go see a doctor or something? What the fuck just happened? Geez man, when the hell did...oh fuck..." he sputtered. "But seriously, are you ok?" The more and more he asked me questions, the more...at ease with the situation he had become. It was almost as if...almost as if he secretly knew it was me, without knowing it was me? It was kind of hard to explain, but he actually seemed to be taking better than I thought; at least, he was taking it better than I was...

"No, I'm...fine, just...fuck, that hurt..." I mumbled, tending to my sore cheek. "I'm sorry."

"Sorry? For what?"

"I just...I didn't exactly mean for that to happen." I rubbed the back of my neck, still not looking Greg in the eye.

"Well, I'm not complaining, mind you..."

"Excuse me?" I asked in disbelief, looking at him.

"Yeah, I mean...you have to admit that it was kind of hot, well, except for that last bit, that definitely scared the shit out of me, but I mean, you're fine, right?"

"Physically, yeah, I just didn't expect that last part either...Why are you so calm about this?" I asked, not really hurt, but just slightly confused. I mean, I would have run away if the guy that was fucking me just suddenly lost his fur and turned out to be a scrawny human.

"Well, once I saw that it was you, I, uh...well I mean, you wouldn't have done it to hurt me, right? So, I decided to risk it a bit. I mean, you aren't a were-fur, right? I'm not going to suddenly change into a bulky tiger anytime soon, am I?"

"No, you're fine, I mean, you lived after I fucked you two weeks ago, right? Oh, fuck-" I didn't mean to admit that. Greg's faced dropped.

"Wait, you were Daniel?"

I looked down at the floor in shame again.

"...yeah, I was."

Please don't hate me, please don't hate me-

"Damn, that was hot, too..." Greg muttered to himself. Whether I was actually meant to hear that or not, I wasn't sure. But still, he wasn't angry at that either?

"So, you aren't mad at me?"

"Mad? Why the hell would I be mad?"

"Well, usually people would freak out at actually seeing someone transform into something else, and then to find out I lied to you-" Greg suddenly laughed. It wasn't as warm as it normally was; I could tell he was still shaken up by the potentially traumatic experience he just witnessed, but he was still somewhat at ease.

"No, no, like I said, it's fine. Honestly. I mean yeah, it was fucking scary, right? You basically melted in front of me. But, then I saw it was you, and you didn't try to hurt me (Though my ass is going to be freaking sore tomorrow), so what was the worst that could have happened?"

I couldn't believe how calmly Greg was taking this, like it was a trivial matter that was completely normal. He was fine with it. His roommate was a tiger a few minutes ago, and that's just fine? Running away from the melting tiger seemed like a more logical option than consoling it. And the dog too? I mean, come on!

"But come on, we should go home. Then you can show me your trick, huh?" Greg smiled at me, almost like nothing had happened. How the hell do you put on a straight face after that?

Getting home was kind of weird. We didn't talk much beyond that, but what little interaction we did have was awkward and hesitant. Greg's clothes didn't quite fit, and I did look rather silly wearing a shirt that was two sizes too large. No one else in the Gym seemed to notice the lack of the huge tiger that was in there, but they also didn't notice the sudden appearance of a scrawny human either. Kyle even said his courteous 'Hello' after seeing Greg and I leave the locker room. It was uncomfortably natural.

I drove on autopilot. I was so out of it that I didn't realized I had parked at my house until I realized that I had been trying to steer a parked car. Shaking my head, I walked to the front door in a partial daze and stumbled inside of my house.

"There you are! It took you long enough," Greg greeted me, still seemingly unfazed by recent events. He was eating a tuna sandwich at the bar, almost completely nonchalant. "So, when can you show mehow to you got to be such a sexy tiger and dobie?" he asked bluntly. I sighed.

"...Can I take a nap first? I need to think about some things first," I requested as I started to head towards my room.

"Are you alright?" Greg sounded slightly concerned.

"Am I alright...No, I'm not."

"Huh?" he asked almost stupidly.

"Greg, I just fucked the daylights out of you as some random ass tiger that was almost twice as large as you. Then, suddenly, bam! Surprise! I'm actually a human who just happens to be your roommate, who just had sex with you two weeks ago as some dog with a made up a name, then lied to you. How are you so calm about this? I mean, fuck, I tried so hard to hide the fact that I was Derek-"

"Daniel," Greg corrected me.

"-whoever the fuck he was from you. Turns out it was me all along! Why aren't you angry?" I yelled, shaking with anger.

I didn't mean to explode, but it felt fucking good to unleash two weeks of pent up emotions on him.

Greg was taken aback. He stared at me, unsure of what to do. I wasn't sure that he expected this, but he still didn't seemed terribly fazed, just mildly surprised, which made me seethe a little bit.

"I don't care," he said, shaking his head slightly, emphasizing his point. I threw up my hands at his apathetic response and stormed out of the room, slamming my door. "Wait-!"

I flopped on my bed, slamming my fist against the pillow.

Why was I so pissed that he wasn't angry with me? I mean, he didn't make any sense, and-

There was a small knock at my door. I didn't respond.

"I'm sorry, David," Greg apologized after a few moments. "I didn't mean to make you mad, but I wasn't concerned because I mean, it's just....you're you, right? I mean, yeah you put on the façade of being Daniel and Lyon, but you were still there, right? That's...that's why I'm not mad. I know you, David. You wouldn't do this to hurt me, so I don't know why you're hurting yourself."

I let Greg ramble on, but I focused on the middle part. Was I really trying to be someone else...?

"Look, I know this is kind of weird, but I've grown...attached to you. I'm rather fond of you. I like you. You're a cute guy, and...I'm willing to look past today. I mean shit, yeah it scared me, but...it wasn't worth losing you for it, you know what I mean?"

I was stunned. I was still hanging onto the painful truth in his earlier words, and now this new revelation? I thought back why I originally tried the sample pills. Part of it was that I was dissatisfied with myself. The other part was my growing crush for Greg, though not as apparent at the time, and that I'd never be able to physically please him. His words repeated in my head, long after he had left my doorway, swirling around...

Fuck. It made me sick. I was using those pills as an excuse to hide myself from something that I didn't need to hide from. Greg knew what my problems were, and it pained me that I potentially hurt him when he managed to keep himself together about the whole thing...Damn it all! I closed my eyes in frustration, lightly crying myself to sleep.

I didn't sleep well. Rampant thoughts clouded my slumber, dreams were vividly disturbing, and Greg seemed to be in every single one, telling me that everything was going to be ok...

There was another knock at my door. I groaned.

"David, it's noon just to let you know," Greg's soft concerned voice called to me. I rubbed my eyes, feeling the soreness of my chest. Fuck, why were they...Oh yeah. Yesterday seemed so long ago, almost as a distant memory. I stood up, and looked myself in the mirror. My hair was a mess, and my arms and legs had the imprints of my sheets in them. I was still tired, but I wasn't angry anymore at least. I wasn't completely ok, but I was certainly better. Greg was right, though he probably didn't mean to point out my personal issues. I did need to stop hiding behind masks. The pills were not supposed to replace my own self. I sighed, and changed my clothes.

Walking into the living are, I saw Greg on the sofa, eating another tuna sandwich. I was fortunate in that I didn't mind the smell of tuna, so he was free to eat how much he liked.

"You feeling any better?" He gave a small look of concern.

"A little. I, uh...sorry I yelled at you."

Greg swallowed.

"Are you still mad at me?"

I paused.

"I'm more mad at myself than I am at you. You see, I got these pills, and-" I stopped for a moment. How on earth was I going to explain this to him? I mean, I didn't understand it myself, so it'd be a nightmare to explain it to him.

"These pills...?" he tried to make me finish my thought.

"It might be better if I showed you. Could you wait till tonight? It'd be easier that way."

"Oh, I wasn't aware the full moon was this week," he joked.

"I'm not a were-fur..." I mumbled, and headed into the kitchen.

The day continued on slowly, though it was filled with less turbulent thoughts. I mean, I had to tell him the truth, and the best way to do it was to take the final pill. Throughout the day, I'd pull it out of the bathroom drawer and stare at it, wondering what lay inside.

Maybe it wasn't such a bad thing to show him. Maybe I've looked too deeply into this, disturbed by yesterday's events, and made up a whole worst case scenario in my head in that instant. Maybe this was truly my way out of my own repressed self-image issues, and the only way I could fix it is by having someone that's better looking tell me that I'm actually alright.

Maybe I'm thinking too hard, or being too hard on myself. I mean, I can't change what life has given me. I mean sure, I could take this pill and turn into a dolphin/hawk/ant or whatever it does, but it would eventually revert me back to my human body. It was a temporary fix. I mean, it only changed my body. I was no different mentally when I was the doberman or the tiger. I was still me, and if Greg was telling the truth, then he would still like me.

That last thought carried me through the day. I knew that now he had seen a transformation, this one wouldn't completely freak out over. At least, I hoped he wouldn't.

Greg asked me throughout the day if it was time yet, but he didn't ask as if he was forcing me to do something, like a child would to a parent in asking for ice cream. It was more of an inquiry, if anything, and he always let me go back into my thoughts, leaving me in my own privacy.

I thankfully felt better throughout the day. I mean, the more and more I thought about it, the more I realized how blind I was to Greg's attraction to me. The gym membership could be disguised, but the subtly was there. Come to think of it, he almost seemed jealous of Daniel two weeks ago, which made me smile a bit at the thought of me making him jealous of me. I was just glad that my mood wouldn't put a complete damper on things.

"Is it time yet?" Greg asked again some time after dinner. I knew his patience was secretly wearing thin, and I didn't want to frustrate him too much. "I mean, no rush or anything, if you're not up for it, it's fine, I can wait..." I knew that has him being polite. But, I was feeling it too. There was a certain attraction to those pills, and now that I didn't have to hide from Greg anymore, I guess it wouldn't hurt to oblige him some.

"Fine..." I smiled at him, and grabbed three ibuprofen pills from atop the fridge.

"What are those for?" he asked as I led him to the bathroom.

"Well, I guess I should start from the beginning. So, I'd been browsing online for random shit, mostly shit dealing with 'how to improve your sex life' and other pseudosciency things just because it catches my attention, you know?" Greg nodded.

"Well, I found these pills. Their claim was to 'Bring out the beast in you!', or something to that effect. Well, it turns out they actually do. No one knows how or why, they just do."

"Huh. That's...actually pretty awesome!" he grinned. I couldn't help but to grin as well.

"Now, this is the pill," I said, holding up the green pill in front of him. He looked at it with disbelief.

"That's it? Weren't those the supplements you were taking?" I nodded.

"Now, not all the pills are the same color. Apparently, it doesn't matter, or relate to anything regarding the transformation. Daniel's pill was red, but someone else said that it turned them into an orca, as I found out later. I had a blue pill that turned me into Lyon, but someone else turned into a hedgehog. But, this was a sample pack, so I didn't exactly get to choose what I turned into. But if you want to watch," I swallowed all of the pills in one gulp, feeling their familiar weight settle in the bottom of my stomach. "It isn't going to be pretty, as you already know," I said as I made a pained grin.

There was kind of a comical silence as I waited for the pill to dissolve. Greg was looking all around, not sure where to focus as he didn't want to miss any sign of change. I was just waiting for the familiar stomach cramp, so I knew I was good for a while. Minutes passed with nothing happening, and I was actually getting slightly concerned. Did I receive a dud?

"Is...anything going to happen?" Greg asked after ten minutes.

"Yeah, I should be hunched over in pain by now...huh. Performance anxiety?" I joked, trying to lighten the mood. It was kind of poorly delivered, but Greg let out a chuckle.

"Well, worst case scenario is that nothing happens, right?"

"Or, I accidentally took some poison or something, but I've said that for the previous two pills."

"What does it feel like?" Greg asked after another minutes of waiting.

"Well, painful. My stomach cramps a lot almost to the point of where I want to vomit my guts out. As for fur and stuff, it just itches," I explained, unconsciously scratching my arm.

"The tail is like popping a huge zit on your ass. Graphic, but that's the best way I can describe it. I wasn't conscious when I grew my muscles, so I can't tell you how that feels. Then there's the face. That hurts like a bitch. Ow," I hissed, rubbing my neck.

"Is it happening?" Greg asked quickly.

"No, my neck is just stiff. 18 hours of sleep can do that," I reasoned. It was true, but, man, the change sure is taking its time...

"What about your cock?"

"That? Oh...I can't even describe how that feels, really. Perpetual erection is all I can think of. But, I was asleep for that part of yesterday's transformation as well. It feels great, but man, there is nothing quite like it."

"Oh." Greg sounded kind of disappointed. Then he glanced up, eyes widening.

"Oh shit!" he exclaimed as he looked at my arms. I glanced down, and found that soft brown fur was rapidly spread down my arms. My chest felt unbearably itchy, and I quickly removed my shirt before anything too dramatic happened. Brown fur had covered the entirety of my chest, and was continuing its way down my arms, and up my neck. I had been so busy explaining the sensations to Greg that I didn't notice the pin pricking sensation as the fur rapidly emerged from my skin. In fact, if I didn't think about it, I could barely feel it anyways. Either the pain pills were working or I was just getting used to the sensation.

I removed the rest of my clothes, not even caring that Greg was eyeing me over. The brown fur had covered my groin and thighs, and was spreading down my legs. The fur itself was so fine that I could feel the draft of the AC above me passing by. I scratched my face lightly, trying to sooth some of the more apparent itch that was on my face. Greg just stared, not really sure how to handle the situation.

"I know it's not appealing, but I mean-ow!"

My stomach cramped. It wasn't terribly painful, but still jolting none the less. Greg flinched, gripping the towel bar. My body heat steadily rose, reaching feverish temperatures. I forced myself to take long breaths, hoping that I would at least stay calm for a little bit longer. I still wasn't quite sure what I was turning into; I thought I'd become another dog, but that'd be kind of lame in my opinion to have two pills be from the same animal family.

"Are you alright?" Greg asked, concerned.

"I am now, but it's going to get a lot worse. Try not to worry too much, as-fuck!"

Another cramp. I felt this all the way through my legs, reaching all the way to the tips of my toes. As I glanced down, I noticed my toes were almost painfully curled, and no matter how much I tried, I could not uncurl them, or separate them. I was actually starting to freak out when I noticed the nails becoming abnormally white almost like...

...Hooves?

My toes melded together, making the nails all one entity, and the more I thought about it, the more it made sense into how it was becoming my new feet. I felt my heels harden, but there wasn't any pain associated with it. My feet shortened (which was a very weird sensation mind you), hardened again, and soon, my overly white toenails completely invaded my not-so-much-of-a-foot. I raised my legs up tenderly, and set it down, hearing a very prominent clop of my hoof. I laughed to myself, though I was still in pain from my stomach. The thought of literally being horse hung soon certainly made this worthwhile.

"Woah..." Greg exclaimed, noticing my reformed appendage. He seemed to not be as concerned for my well-being, but he still held onto the towel bar. My palms thickened, but I certainly wouldn't call them paws, as there were no claws and they retained the same bone structure.

I almost toppled over as a huge wave of heat filled my body. Greg rushed over to make sure I wouldn't hit the counter as I fell on to my knees, holding my arm all the way down. It was unlike the fever I had which made me dizzy, rather, it seemed as if I was now bustling with energy. It was as if something deep inside of me was swelling, almost to the point of being uncomfortable. Everything became fuzzy and out of focus as I felt something surge deep within my body, reaching every single cell. Every breath I took was labored, but what surprised me was that my chest never seemed to relax. It felt tighter and tighter under my skin, almost as if-

"Holy shit, you're growing!" Greg exclaimed, his eyes widening in a fearful excitement. Looking down, I found that it was true. More and more muscle seemed to pack onto my chest. My arms thickened, and Greg's paws seemed to shrink in contrast. My head was still fuzzy but it was actually feeling pretty good at this point.

I groaned again as my face expanded forward. Bone almost seemed to rub against bone as it grinded, popped, and actually broke to form my new muzzle. I watched through squinted eyes as my nose got further and further away from me, darkening in color. I grabbed the sides of my head as my ears painfully moved upwards.

"Fuck!" My stomach cramped again, and it was by far the worst one yet. Greg was still holding on to me, trying to comfort me through this ordeal. My bones felt as if they were splitting apart. More cracks and pops echoed through the bathroom as my body shifted. My back felt abnormally tense, as if it hadn't been popped in years. But even with the massive pain almost blinding me, I realized that I was getting taller. My legs forcefully spread apart as my quads grew longer and thicker. My shins ached as they lengthened at the same rate as my thighs did. I watched hazily as the floor got further and further away. It all seemed so surreal, and if Greg hadn't been there as an actual reference point, I probably would have blamed delirium for this sensational experience.

The massive heat within my body surged once more. I screamed powerfully, voice dropping as more and more muscle packed onto my body. My arms thickened again, surging in width as the muscles became thicker and harder. Veins quickly rose to the surface, adequately supplying my new found muscle with blood and nutrients. I flexed my arms, watching as the fibers jumped, veins rolled around under my skin and fur, and the entirety of my bicep swell larger than any I had seen before. I relaxed, and the shape still retained. I flexed it again, watching it swell to ever greater dimensions. I couldn't help but to grin. My back was finally loosening up, and I was actually able to move it. It felt abnormally thick, and as I turned towards the mirror, I couldn't help but gasp.

Even on my knees, I could easily see over the counter. My head was definitely horse shaped, though the mane hadn't grown in yet. My neck was thick, corded with the smaller muscles and connective tissue, and small traces of veins could be seen running down the sides. My traps almost seemed to loom over my upper body, thick mounds of muscle that would normally take years to develop. They spread from my neck to my powerful shoulders, using every bit of space possible.

My thick shoulders were to die for. Every single muscle head was on display, several more cords of tissue lined the thick muscled joint, and deep grooves filled in the spaces between the cords. My bicep was cleanly cleaved in half, and at the furthest stretches, striations were cleanly visible. A thick vein ran from my shoulders to my elbow, and even then, several veins branched out perpendicularly from the center vein, leading to my triceps. I turned my arm and fully extended it, watching as my triceps flared outwards. The juicy horseshow shape looked intimidating. Ripples, bumps, veins, and thick grooves ran all through the out two tricep heads, and the middle head was lined with nothing but thin veins and clean striations.

I returned to my original position, and slowly stood up. Greg assisted me as I was still unstable. The first thing I noticed was that I was fucking tall. Taller than Lyon had been by a good foot and a half, and I could barely see anything above the base of my neck. But shit, being seven and a half foot tall horse? I'd take it. Greg looked unnaturally small compared to me, both in height and musculature. I looked over myself some more, continuing to visually explore my body.

My chest was composed of two magnificent slaps of muscle. My pecs were evenly thick from top to bottom, veins drizzling along the surface. Long striations filled the middle of my meaty pecs, going from the jagged centerpiece to the edges; they even seemed to wrap around the muscle, deep into my sides. My black nipples were forced to point downwards at the edge of my pecs. They jutted out so far that they created a decent shadow along my abs from the overhead lights.

I couldn't even to begin to describe how fucking hot and sexy my abs looked. Tight skin covered eight large mounds of muscle, flanked by thick obliques. I turned my body some, enjoying the anatomical display of my newly formed physique. Each slight movement I did moved about fifteen different muscles, and all of them were easily seen. I tensed my abs, watching the swell slightly as they crowded for space along my front. They receded slightly when I relaxed, leaving a small bit of a space between each one. Three smaller veins led to my groin, which also hadn't changed yet, though I did have a raging boner, which looked comically small on my new body. Greg apparently noticed it too, and seemed very disappointed.

"Don't worry, it'll happen later...there's usually a pause," I grinned at him. He still gave me a slightly questionable look, but here turned to noticing the other changed of my body.

My waist was trim, though I still couldn't wear any of my pants because the bone had gotten so large. Smaller muscle groups graced the sides of my thighs, allowing for powerful lateral movement. My quads were thick and juicy, particularly towards the knees, where the two muscles that flanked it were large and round, and striations once again showed on the surface. Several thick veins ran down my thighs and through my thick knees, eventually making their way through my calves.

I've always disliked clichés somewhat, but my calves were diamonds. Glancing down and moving my foot-no, hoof around, I watched as they flexed and relaxed, swelling to a very impressive span. I could probably hold something with the split of my calves if I wanted to, they were that strong. I returned my gaze to the mirror, and turned around, craning my neck to see my back side.

I didn't even know where to start. My back was a vast expanse of muscle, and there was no way to really see it all in one glance. Lats spread outwards, seemingly giving me a wingspan. Rhomboids lined the center, creating a large diamond of muscle. Thick columns of muscle flanked my spine. The crisscross pattern of muscle fibers formed my lower back. The rest of my traps flowed into my neck, thick and juicy. I could probably flex in ten different ways and not see every muscle. I put my arms at my sides and flexed my lats, watching them spread even further.

"Oh god..." Greg moaned beside me. I had been so focused on myself that I almost forgot he was there. His eyes were rolled back into his head, and a large stain now occupied the front of his pants.

If there was ever a boost to my ego, that was it. I just made a guy cum by flexing. Shit, that felt good.

My ass was hard and compact, and yet still looked rounded. But if I flexed them any, sharp muscles came out of the texture, showing their true power. Srprisingly, I didn't have a tail yet, but I figured it'd come in with my mane.

I was a muscle god, no doubt about it. I grinned down at Greg who had recovered from his orgasm, scratching the back of my bare neck.

"Man, we haven't even gotten to the best part yet, and you already shot your load?" I teased him, still furiously scratching my neck. I felt the fur get thicker, and glancing back to the mirror, I watched as my black mane finally grew in. I shook it, feeling the even softer hair flow back and forth. A pin pricking sensation above my ass directed me to those mounds, and I found long hairs slowly extending outwards, darkening in color and slowly thickening into a tail. The hair there was similar to my mane; it was light and black, and it almost reached my knees.

Greg looked at me with wonder. I looked at myself in wonder. All I needed was the envied horse cock, and I'd be the wet dream of every single guy in town.

"Gah...!" I clenched my stomach again. It was a mild cramp, but it still hurt as if someone lightly struck me in the stomach. The pain traveled downward and focused on my groin, intensely heating it up. Greg and I watched in fascination as a large flap of skin swallowed my six inch cock whole, swiftly becoming my new sheath. My balls visibly swelled as they started to hang lower and lower in my sac, which was also rapidly expanding. The pressure was intense. It felt it someone was taking a bicycle pump and inflating my balls one pump at a time. They grew some more until they were the size of apples. They hung not quite as low as I thought they might, but regardless, my balls were pretty impressive. The rush of additional hormones rushed through my blood stream, quickening my heartbeat and making me feel flush, but thankfully not dizzy. My sheath slowly stretched along my belly, soon overtaking my previous dick size. Damn, it was going to be a monster.

Blood pooled in my groin. I felt a muscle I wasn't familiar with relax, and quite a bit of soft flesh sprung from my sheath. It was also black in color, and even soft, numerous veins crossed along the flaccid shaft. I picked it up with my hand. It was so warm and heavy...I let out a breath. Even holding it was intense, sending shivers of anticipation down my side. I let it go and it noisily flopped against my thigh, slowly hardening.

Suddenly, I felt one of Greg's paws on my thighs. He grabbed my expanding cock with the other and started sucking on the blunt tip. I moaned out loud and lightly thrust my hips into his face. Under his ministrations, it lengthened and thickened as it pulsed along, both pleasurable experiences combining. The shaft felt so heavy, pulling downwards at my groin...

Soon, Greg couldn't get his mouth around it, but that didn't stop him from trying to lick every single centimeter. It still grew in size, throbbing along the way, until it reached the countertop. Having Greg's warm paws and mouth tending to the shaft and having the blunt tip of the shaft touch the cold countertop was a very nice combination of temperatures, causing my balls to pulse slightly, send a jet of pre across the sink, splashing against the faucet.

With a powerful throb, the erection was complete. It had to be at least twenty inches long, if not a little more. It reached from my groin and barely hung over the bowl of the sink, all of it hard, thick, and covered in thick veins. Pre was beginning to ooze out of the tip, slowly dripping down towards the drain of the sink. Greg was now lapping the underside, moving his paws up and down the shaft. I braced myself against the sink as my balls gave a mighty twitch. I moaned out as Greg continued to please my shaft. With all of the other sensations from earlier, I knew I wouldn't be terribly long.

Sparks flew behind my eyelids as my hips thrust forward, sliding along the cold porcelain. A new spurt of pre lanced from my cock, slowly draining itself. I looked down at Greg, who seemed so focused on my shaft that nothing in the world matter more than my release. His smooth, wet, and warm tongue gliding across my cock, his strong paws stroking the areas that he wasn't licking....the combination made me dizzy with pleasure.

"Fuck yeah, Greg, keep going...I'm so close... oh fuck me!" I yelled as I came, almost unexpectedly. A giant thick rope of cum shot out and splattered against the faucet and mirror with such a force that some of it actually ricocheted back onto my cock, dripping onto Greg below. Two more giant ropes forcefully shot out after that with the same velocity. Greg looked at me with wonder as several droplets of cum streaked down his face, and I felt a smaller wet splatter against my leg. Greg had come again without me touching him in any sort of way.

More and more blasts of cum fried from my shaft, and though they lacked the velocity to bounce back onto me, the volume was still just as great. The sink was beginning to flood as the rate of the cum going down the drain was less than the amount entering it. Smaller volleys of fluid added to it, and soon, all that left was a dribble of cum leaking from my cock.

Even after all of that, I was still breathing hard. My heart pounded in my ears. I couldn't believe that I just had filled an entire sink of cum, and my cock was still throbbing lightly as if it could do it again. Greg crawled out from beneath me, awe struck at my output.

"Damn, it'll take forever to get the smell out..." he grinned at me through my reflection. I let out a tired laugh before slowly let myself down to my knees, my cock softening and retreating back into its sheath.

"You alright?" Greg asked kneeling by my bent knee.

"Yeah...shit, it takes a lot out of you...I may need a nap."

"Damn, this is fucking hot, man. Definitely a good find," Greg smiled at me, patting my thigh.

"Thanks," I mumbled, vision growing blurry, leading me to slumber once again.

I didn't realize I had fallen asleep. I mean, it was kind of expected as I had done so after every transformation (though Lyon's was more of a nap), but it was hard to tell the difference between my dreams and reality. Various images of Greg and I fucking each other filled my mind, but the turning point was when I realized that I was human in all of them. That was the strange part...but was it really so strange? It made sense to some degree, but--why is my groin wet?

I opened my eyes. I glanced down, still somewhat dazed, to find Greg lapping my hefty balls. I wasn't erect yet, so he must have just started. I was in the bedroom though, and I couldn't complete the jump from the bathroom to here, but Greg must have moved me...fuck, what time is it? I tried to ask him, but all that came out was a moan.

"Damn, up already? So much for the surprise," Greg laughed. My head hurt slightly, but at least I was conscious.

"What...what time is it?" I asked, rubbing my face.

"About ten in the morning or so. You were out for quite a bit," he chuckled.

"So I was. Anyways, what are you doing?"

Dumb question, I told myself.

"Well, I figured I'd suck your dick. You know, stuff like that," Greg said matter-of-factly. My stomach rumbled very noisily.

"Can I get some breakfast first?" I asked.

"Fine..." he said in mock disappointment.

I stood up from my bed and stumbled forward. I was still not used to my new body, but I'd live. I guided myself out of the room using one hand on the wall. I almost hit my head on the door frame, but ducked just in time. That was going to be annoying after a while, but for this body it was a miniscule sacrifice.

Breakfast went by as normally as can be, minus the fact that I was now seven and a half feet tall, well over 240 pounds, and built like a tank. I was also proudly naked because we certainly didn't have clothes that fit me, not that either of us were complaining. I ate three times as much as I normally would, which was expected given my body size and the normal amount of calories I burned just by existing. It was almost comical to watch me move about the house; I was a lot more clumsy, but with that, a lot more dangerous. I hit the edge of my shoulders numerous times throughout the day as Greg was out getting groceries and other errands, leaving me to do as I pleased for the time being.

Surprisingly, beyond the ball play this morning, he didn't touch me or even really try to seduce me in any sort of way. I wasn't complaining too much...my body was still a little fuzzy from last night's event, but I was getting better throughout the day, and with that, a little horny as well.

Greg returned home after a few hours. I took a small nap on the couch, but I instantly woke when I heard him enter. Actually, I heard the clatter of cans when he entered, but you know.

"God damn, you're sexy..." he muttered lustfully still staring at me. It was hard not to stare as I covered the entire span of the couch. The poor otter never took his eyes off of me as he picked up the four cans he dropped, practically raping me with his eyes.

Actually, since he's the bottom, he was probably being fucked in his mind. I grinned as he took the remaining items into the kitchen, leaving them on the counter. I got off of the couch and followed him into the kitchen.

"H-Hey!" he yelled in surprised as I grabbed him from behind, pulling him into a big bear hug and lifting him off of the ground. His body felt light in my arms, and even as he squirmed, my arms would not give. I set him down after a bit, leaving him somewhat flustered.

"Damn, David, warn me next time!" He continued to put the items in the cupboard. I helped by placing the items on the top shelf so that Greg wouldn't have to get a chair or something. Soon, all the groceries were put away.

"So, now that that's done-umph!" I didn't let Greg finish. I kissed him feverishly, forcing myself upon him. He melted into the kiss after a second of finally realizing what was happening. His tongue intertwined with mine passionately.

"Geez man, I didn't know you were that pent up from last night." Greg winked at me. "Come on, follow me..." He took my hand, and led me to my room. As I sat upon the bed, he slowly stripped out of his clothes. Hard and toned muscles appeared as he lifted his shirt. It almost like looking a scaled down version of my current body, and knowing the fact that he put lots of hours of hard work into his body made it that much more alluring to me. He pulled of his pants, revealing his muscular thighs and claves. His underwear had a growing bulge in it, and I felt my own sheath quiver at his arousal. The underwear was last to fall, revealing his eight inch cock, already leaking with pre.

He straddled my lap, drawing my mouth in for another lustful kiss. It was much more sensual and tender than my feverish one, though arousing all the same. He pushed me backwards, slowly working down my neck. I shivered under his kisses as he found himself at the massive expanse of my chest. I grunted as he stuffed his face in between my pecs. I flexed them, lightly trapping his head. He groaned and pinched my nipple causing me to moan. He pulled his head back, and lapped at the sensitive nipple.

"Oh..." I moaned, rubbing his back. My flaccid cock emerged from my sheath, slowly hardening. Greg's paws roamed down my abs, feeling every bump, nook, and cranny as he ghosted along those hardened lumps of muscle. I grabbed his ass, forcing his hips to grind into me. His hardened cock throbbed in the crevasse of my abs. Grinning, I flexed them, trapping his cock in a similar manner as I did his head, causing a spurt of pre to land on my chest.

"Oh sweet mother...Damn, David..." I grinned at his reaction and flexed again. He hit my chest, grinding his cock along my abs. Having this effect on him was certainly fueling my arousal. Speaking of which....

My monster of a cock was fully erect now, sticking up behind him and the flared head almost reached the base of his neck. I tilted my hips back, letting his ass fall into place against my sheath and hardened shaft. He looked behind him, gasped, and ground his hips against my molten shaft, sending burst of pleasure to my balls.

"God damn..." I breathed. It was still sensitive, but I wasn't quite as ready to blow as I was yesterday, so I at least had a decent amount of time.

He turned to face me again, kissing my softly on the lips again.

"So...how are we going to do this?" He asked in a husky tone. "It isn't exactly small..."

"You could fuck me for a change," I suggested. I had thought about it for a bit, and it was obvious that I would actually cause some damage, so the best way for us to get off together is for him to take me. I know he's a bottom, but sometimes it's good to experience the other side of life, right?

He thought about it some and nodded his head.

"It'd be for the best. I've always wanted to try fucking someone instead, so what better time than now?"

"Fair enough." I got off of the bed, and presented my muscular ass to him.

"Geez, such a sexy ass you have..." he moaned as he rubbed it with his paws in circles, bunching up the muscle. I flexed slowly, feeling it harden until resembled an X rather than two globes of muscle. I felt warm breath behind me, and soon, his wet tongue was upon me. I groaned as he vigorously lapped at my hole, almost taking no time for my preparation.

I found that I didn't need much preparation anyways as his tongue slipped right in, invading my depths with the wet organ. I moaned as I moved my hips around a bit, trying to make him go deeper inside. I started to stroke my hardened shaft, pre leaking all over the bed. He circled around, making sure I was thoroughly soaked before pulling away. The absence of his tongue was quickly replaced with the blunt tip of his hot cock.

"You ready?" he asked.

I pushed my hips back, effectively sinking his cock into me.

"Oh fucking hell..." he moaned. I groaned at the sensation of being penetrated. It was bigger than I had anticipated, and certainly filled me up to a certain degree, but it was still a smooth entry. My cock lurched, spraying the sheets with another spray of pre.

He gripped my hips and pulled out. I didn't have much time to appreciate the absence of his meat as it was forcibly shoved right back in, causing me to grunt in slight discomfort. I mean, I knew he wouldn't hurt me, but some time to adjust would have been nice. He thrust in an out at a moderate speed, effectively jamming into my prostate each time. I moaned continuously, occasionally letting out nickers and whinnies, something I really had no control over yet. My cock was throbbing in front of me, and soon I felt his paws on my dick as well.

"Oh yeah... keep going," I encouraged him. He picked up the pace slightly, and I could feel the pit of orgasm steadily approaching. In and out, in and out, I was slowly entering a delirious haze. Feeling him stroke in time with his powerful thrusts was arousing as hell. His head was directly behind my neck, and I felt his warm breath as he huffed away, stuffing his cock into me as hard as he could.

His thrusts were getting sloppy and messier; pre was flying out of his cock and coating my insides. His balls slapped mine, and the twinge of pain it brought mixed in so well with the pleasure of him fucking me mixed so well together that it was hard to tell the difference between them.

"More..." I moaned, reaching behind me and pushing his head towards mine. We kissed fervently, riding out the pleasure as long as we could. My thick shaft bobbed spewing pre on my bed. My balls steadily drew upwards, showing the sign of my inevitable orgasm. His paws danced along my cock as I braced myself against the bed, ready tofall over the edge.

"Fuck!" I yelled and neighed at the same time (which was an interesting sound in of itself), feeling my balls lurch upward and my tip flaring outwards, ejecting massive amounts of cum against the wall. Ropes upon ropes fired, messing up my wall and sheets, coating them with a fine layer of fluid. Greg grunted behind me, and I felt his cock shoot cum deep inside of me, flooding my innards as well. My orgasm was just impressive as the previous one, thoroughly soaking my bed. Even after Greg finished repainting my intestinal tract, small bursts of cum lewdly spilled from my cock adding to the mess.

"God man...fuck, David...you have an ass of velvet. No one on earth could last more than four minutes in there..." Greg grunted as he collapsed on top of me, giving me a big hug. "And that tool of yours...feeling it shoot of like a fire hose was something else. Maybe one day, I could take it..."

I fell on to the bed, and rolled over onto my side facing him.

"Maybe one day, we can make it happen," I said with a sultry wink. "But for now-Shit!" My stomach cramped. God damn, so soon?

"What is it?" Greg asked, suddenly concerned.

"Fuck, the pills...they're wearing off-God damn!" I curled up, feeling the painful feeling spread outwards towards my hands and hooves.

A boiling heat like no other filled my bloodstream. I watched as my fur fell out in patches, falling into the puddles of cum that I made, making sticky clumps of fur and fluid. Greg stood back, seemingly torn between making sure I was alright or running and calling a doctor.

"Are you going to be ok?" He asked, biting his nails.

"Don't worry-ach!"

My hooves fell apart and split into multiple pieces, transforming back into toes and toenails. My calves cramped, and I watched them as they painfully shortened, making me grit my teeth. My face flushed with heat, and soon the familiar feeling of bones breaking and grinding against each other returned as my nose inched closer to my face. I felt my ears move back to the side of my head, and my neck stiffened up as it shortened as well. My body felt as it was deflating; I watched in pain as muscles receded back into my body. All over I was in pain. My tail fell out at some point, and all of my joints seemed to become inflamed as they readjusted themselves. My vision blurred, and I cried out once more as my stomach painfully churned.

"Fuck..." I groaned as it suddenly stopped. I was a mess. I was covered in horse fur, hair, and my own seminal fluids from rocking back and forth on the bed. Greg was in the corner, covering his face with his fingers separated.

"Is it over yet?" he asked after a moment.

"Yeah, I think so...damn...that was fucking awesome too...."

My depression returned. I was pitiful, and I didn't want to be seen like this. I sat upright with head hung low, glancing at my inadequate crotch.

I felt furry arms around me. Greg held me tight, not concerning himself with the messy fur that had stuck to my naked skin. It was warm, and I knew he was trying his best to console me. It was painful, both physically and mentally, for me to go through this, but if there was I needed, it would be him.

"I'm here for you, you know that, right?" Greg asked, sensing my insecurity. There was a comfort in that, but it was still not enough to override my feelings completely. "Let's go take a shower, ok? We can clean this up later, alright?" I nodded. I could mope here all day, but a shower would make me feel a bit better.

I trudged behind Greg to the shower, fur falling off of my body as went down the hallway. Greg stepped into the shower and turned it on and making sure that it was a pleasant temperature.

"You doing alright?"

I sighed.

"Mostly. Every time I change, it gets better and better, but...but I think about why I'm doing this, and it just makes me miserable. I'm cheating at life. I'm playing God with myself, and it's only making me miserable."

"How so?" I watched as Greg started to wash himself. I was envious of his body. Normally, I'd want to touch it, feel the hardened muscle ripple under his skin, feel the heat of his body and wrap my meager hands around his hot cock...I shook my head. I slowly worked up a lather with the body wash, but put minimal effort into it as my mind was filled with numerous thoughts once more.

"I don't know. I just...I think that every time I have sex with you, it isn't because of me; it's because I'm now the epitome of whatever species I turn into. I mean, fuck, who wouldn't want to be fucked by a sexy tiger horse or dog, built with supple muscles and a huge cock? I'm just a pitiful human, you know-"

"Stop right there." Greg interrupted me sharply. I looked at him with confusion.

"First off, I think you're sexy as a human anyways. Why do you think I'm still your roommate? Why do you think I wanted you to go to the gym with me? It's because you're sexy, and I wanted to spend time with you. Secondly, I let you fuck me all three times. I'm not just some horndog that turns up my tail for anyone. That person has to be special."

"But you didn't know it was me until I told you."

He knowingly tapped his nose and smiled.

"Instinct. I didn't realize it until ten minutes ago...your scent never changed. Remember I asked if I knew you back in the gym? You smelt familiar, and it wasn't until now I realized...you still carry the same scent regardless of the change. I mean, yes I didn't know it was you, but there something behind that smell. I'm not sure what it was, but I'm glad I went with it. I love you, David. Don't let the whole issue of being superficial bother you. Yeah, it was hot. But not only was it worth it, but your character retained throughout each change. You didn't let the pills change you. That means a lot more that you were using this," he pointed to my chest "rather than this," he pointed to my groin. "I love you. Not Daniel, not Lyon, not the horse. You."

My heart fluttered. He loved me...I mean, he admitted fondness for me, but love...?

Tears formed at the corners of my eyes and let out a pained sigh

"Oh god, I didn't make you mad, did I?" Greg freaked out a bit.

"No, I...I love you, too, Greg," I admitted as I hugged him, standing under the cooling shower as it washed the remains of the fur off of my body.

"Fuck, harder, David!" Greg grunted underneath me. My dick pistoned in and out of his warm hole, edging us both towards our respective climaxes.

"Fuck, Greg..." My dick was ablaze with pleasure. My balls ached, as this would be the fourth time tonight, too...I never knew I had this much endurance, and apparently Greg didn't either.

"Oh fuck...." He moaned underneath me. I felt his cock throb mightily as it spewed out whatever cum remained in his balls. His hole clenched around my dick, effectively pushing me to orgasm.

"Greg!" I yelled out as I came inside of him, adding a small amount to the cum that was already in there. I flopped on top of him out of exhaustion as my cock throbbed, still sensitive.

"Geez...four times, man...didn't think we had it in us..." Greg huffed. I felt his heartbeat through his muscled chest, and took comfort in it. His body was worm, and the weight support it carried surpassed any bed.

"Man, you look sexy when you're exhausted," I grinned, kissing him on the lips.

"You don't look so bad yourself...I'm glad you started to go to the gym with me, results are already showing..." Indeed they were.

Five months had passed since our free samples adventure. Since then, Greg and I had gone steady, and worked out a lot more than we used to. I put on a good five pounds of muscle since then; I actually had a four pack to speak of! Of course, with Greg's dietary guidance as well, I was sure to make good results in the near future. He smiled at me warmly as he looked me in the eye.

"You're birthday's tomorrow. Anything you want?" he asked.

"A good fuck?" We laughed at that thought; we've actually had sex almost every day it seems, though sometimes we needed a break now and then.

"Well, if it's alright with you, I already got your present."

"Oh? Am I allowed to open it now, or do I have to wait?"

"Here," he got up off of my bed, and pulled out a package from behind the door. How did I miss that?

"It just arrived today. I think you'll enjoy what lies inside," he grinned.

I tore into the package and found a familiar label underneath.

"No way..." Greg still grinned as I opened the box and pulled out a card.

'Happy birthday from Meta -Labs!' it read. I glanced at the opened box. Tin foils filled with capsules of various colors filled the container. I looked at Greg with my jaw dropped.

"Yup, got one for about eight different species, including our favorites," he winked. "Also, they were testing out some 'premium pills', so I got a sample of that as well."

"...What do they do?" I asked.

"For a month, you change into whatever you select. Here's the cool part: You can go online, enter your preferences, and they make a pill for it."

"What preferences?" I asked, trying to hide my partial excitement.

"E-v-e-r-y-t-h-i-n-g. Species, color, height, weight, build, genital size, everything. Well, everything except gender. I think you'll like what I've chosen for you," he grinned.

"Oh fuck me..." I returned the grin. He drew in close and we kissed again.

"I love you, David."

"I love you too, Greg," I said as the box fell off of the bed and landed on the floor.
