Derek Ludwigson, a 24 year old Caucasian male struggling to make ends meet opens his apartment door after a long, stressful day at work. His job consisted of mostly sorting at a GoodWill just down the block near his apartment complex.

Closing the door once he enters his home, he releases a long, relaxing sigh. His eyes scan over his apartment. Everything seems to be in place.

The small television and sofa are in the tiny sitting area only a yard away from a small kitchen. Near that, on the opposite side of a set of counters is a small room, where his bed would be - if he could afford to make payments.

For now, Derek finds solace in resting on the sofa, even using it as his bed. He'd always liked napping on the sofa growing up, doesn't seem to be doing him any harm so far.

On his kitchen counter, Derek sees the red light of his answering machine blinking, begging for his attention. He kicks off his shoes and tosses his coat carelessly to the floor, heading straight to the fridge. On his way, he presses the message button.

"You have... one... new message. First message:" the answering machines feminine voice recording alerts. The message plays.

"Hello, Mister Ludwigson, this is Doctor Belter calling from A.T.L Industries just to let you know that you've been approved for a drug testing session in your local clinic, uhh... To answer your question about compensation and payments, you'll be paid five hundred dollars for this test, so we hope you're still interested. Really helps out the research. Uh, if you have any questions or concerns about this, just give us a call back, you've got out number. Thanks again, and have a good day."

A smile streaks across Derek's face as he feels a sense of relief; five hundred dollars could be heat and rent for a month and groceries for a couple of weeks.

Derek picks up the phone and dials the number he was given. His heart sinks when he hears the ringing.

"Hello, A.T.L Industries this is Pam."

"Hi, Pam, I'm Derek Ludwigson, calling about the drug trials here in New York, I'm accepting the offer from Doctor Belter, he called me while I was out."

"Of course, Mister Ludwigson! Let me just check a few things here," says Pam, followed by the sounds of keyboard keys tapping at a fast pace. "Alright, Mister Ludwigson, your trials are available today at three thirty, tomorrow at three, and Wednesday of next week around two in the afternoon - can I schedule you for one of those?"

"Of course! I'd like today at three thirty, please! I appreciate this."

"Not a problem, Mister Ludwigson! You're scheduled at your local clinic for this evening at three thirty. Is there anything else I can do for you?"

Derek smiles and sighs, "No thanks, Pam, thanks so much! You have a good day."

"You too, Sir. Goodbye."

The doctor's office is rather plain. The walls are white with posters plastered about, relevant to health and body parts like the nose and ear, giving in-depth explanation about how they function.

There's a small knock on the door and to Derek's surprise, it's Doctor Belter, himself.

"Hey there, Derek, I'm Doctor Belter, I called you this morning."

Derek reaches out and shakes Belter's hand, "Yeah, I got it. That's why I'm here," he smiles, "So what kind of drug am I testing?"

"Well," Belter says, pulling up the only stool in the room, taking a seat before the examination table, facing Derek, "this is a new test that our industry is working on. You know how primates and humans only differ in DNA by nearly two percent... well, this pill is designed to help us communicate with primates temporarily."

"So... this is a mind-altering drug?" Derek said, a bit uneasy.

"In a sense, but it only heightens the cell in the brain that everyone has laying dormant, the cell that controls telepathy and other energy-related, atom-related, and molecule-related forces." Belter explains, taking out a pen from his pocket, reaching behind him on a counter and grabbing a clipboard.

"Wait, so you're telling me science and medicine buys into all that psychic-stuff?"

"Not psychic, Derek, scientific. The human brain is capable of so much - there are people in the world who do perform 'psychic' activities, but none that we know of that deciphers some kind of communication."

"Then that's what this pill does - heightens that and lets us talk to beings similar to us who... aren't... us?"

"Eh... yes and no... this one is designed specifically for primates. The diagnostics team in my lab knows much more about this than I do, I'm just the head of the research and distribution department."

"But... it is safe, right?" Derek asks, worried.

"Completely safe!" Belter says, a smile on his face, "Your medical records show that you are in perfect health, and there is no way this test could go wrong for you. Either the pill activates that part of your brain, or it doesn't. Nothing else should be affected... except..."

"Except...what?"

"The pill, like all medications, has a side effect. Your facial hair and hands... some appearance-based aspects may change, but only temporarily. The drug's affects themselves are tested to last a week, but the side effects should not last more than a day."

Derek loses himself as the doctor continues on, thinking about what the pill would do to him. Would I grow a massive beard or something? Will my hair like... fall out?

"... can call us here if you have any problems. Sound good, Derek? Want to go through with this?"

"Well... I can use the money... I'm going to go for it," says Derek, his hands pressed together between his lap.

"Alright! Just wait here and I'll be back with the pill. If you change your mind, we can either reschedule or do whatever you decide." Belter says as he leaves, leaving the door slightly ajar.

Derek sighs, his heart thumping. Drug trials always go wrong in the movies or TV shows... but I really, really need this money. Besides... the side affects go away in like a day... and nothing should happen, even if the drug works, it only heightens a sense... nothing else. Come on, chicken-shit. Just man up already - I need that money!

Belter returns with a small metal tray, a pair of tweezers, and a plain white pill bottle.

"Alright! So here is the pill, all ready for you take when you feel ready for it. If you want, you can take a look at 'em, just sort of get comfortable with the drug, it's all up to you."

Belter opens the white bottle, reaching into it with the tweezers, revealing a small, green capsule. He plops it in the tray and shows it to Derek.

Derek examines the green pill, his thoughts racing and his heart jumping with worry and what-if's.

Finally, Derek swallows his worry and pops the pill into his mouth, swallowing. Belter hands him a small paper cup of water, which Derek drinks entirely.

"Alright, how do you feel?" Belter asks.

"I... feel fine, I guess." Derek says.

"Good - now if you have any concerns within the next 48 hours, go ahead and give us a call."

"Okay, thanks for..."

"Also, I forgot to mention, try to stay away from sexual activity for the next week. Since this pill is activated mostly in the brain, we don't want anything to go wrong in terms of hormonal imbalance or the brain's signals dealing with arousal... technical stuff."

"No problem," Derek said, a little disappointed, being reminded that he doesn't have a significant other.

"Pam will have your check waiting for you at the receptionist desk. Thanks for helping out with our research, Derek! Can we count on you in the future for more drug testing?" Belter asks.

"Well, I dunno just yet," Derek chuckles slightly, "We'll see how this trial goes, and then I'll decide."

"No problem! Thanks so much Derek," Belter says, collecting his things and heading for the door, "You take care and have a good week."

"Thanks, haha... you too, Doc."

The walk home is a bit strange. Derek can feel his feet swelling, pulsating inside his shoes as he walks. His hands feel almost the same, like they're slowly inflating like latex gloves.

He takes his hands out of his pockets and looks at them, still walking. His hands have gotten bigger, like ape's hands. His knuckles are slightly swollen at the cartilage, and even his fingernails seem a bit off. _My God... he wasn't kidding. My knuckles look so... what the hell?_Derek feels his face - already, thick sideburns are growing along his jawline, which is beginning to feel a bit sore.

Derek walks a bit faster, hoping to get home quickly before anyone can see his changing body, but not before he stumbles over his feet. He lands on his knees and slowly sits down, looking at his feet. His shoes have ballooned twice their size.

He immediately takes off his shoe and sees his foot has gotten much bigger - he's gone up at least another shoe size, and wider. Wow... I hope five hundred was worth it...

Derek wiggles his large, ape-like toes, squeezing them, making a fist with his feet. Heh... that's actually kind of cool. It's like another pair of hands!

His tendons inside his legs feel strange as he releases his monkey-foot fist. Squeezing again, he can see a bit of hair growing out from his pantleg. Pinpricks can be felt all over his body; he decides he should get home fast.

Derek stands, holding his shoes under his arm as he walks home barefoot, avoiding eye contact with passersby.

Finally, he reaches the apartment complex, enters the hallway and gets to the elevator to reach his floor. The elevator opens, and to his relief, the elevator is empty. He steps inside and watches the doors close.

Derek leans his head back against the velvety wall of the elevator, placing his hands over his face, running them through his hair and over his ears - that's when he notices.

My ears... they're... m-monkey ears? Derek wiggles his ears and smiles a little, a bit amused. I shouldn't be enjoying this so much but... it's kind of funny.

Derek runs his fingers over his ears - they are actually his ears. He can feel his fingers on his ears - they actually _have_turned into real monkey ears.

The elevator stops and the doors open to an empty hallway. Derek's apartment is just a few strides away, so he quickly rushes to his door, unlocks it, rushes inside and closes, locking the door.

Derek sighs in relief as he heads to his bathroom. Man... maybe a shower will help calm my nerves.

Derek takes off his shirt and jeans, tossing them to the bathroom floor. When he turns to face the mirror, he sees that his body has already begun to sprout hair. Very thick, dark hair. The pinprick feeling was the hair growing all over his body. Before his eyes, like vines, the hairs grew longer, covering his flesh.

What the... I'm looking more and more like some kind of monkey! Calm down... it only lasts a day.

Looking closer at his face, Derek can see the changes occurring right before his eyes. His lips grow a bit thicker, his nose grows wider, stinging as it does.

"Aagh!" Derek hisses at the small amount of pain in his face, "G-gagh!" The cramping gets worse; his jaw inches forward and his nose even manages to smash down slowly, looking like a gorilla's nose. His forehead extends, causing Derek to gain a migraine. What is going on? This pain... it's... augh!

Soon, after a few cramps and muscle spasms in his jaws, his face looks very similar to a gorilla's face. His body still stands upright, coated in thick, dark hair, itchy at first, like a badly knitted sweater.

His stature was the very same as it's always been - it only looks as though he is wearing a gorilla costume. The only thing that hasn't changed about him is his genitals.

Okay... I don't think I can shower just now._Derek thinks to himself, _but... if the side effects are working... that must mean the pill's intentions are working. Maybe I can give that a try? It'd help the research... and after all... I did sign up to do this.

Derek leaves the bathroom and enters his bedroom, finding a long sleeve shirt, long, baggy jeans, a pair of wide, roomy boots he used for a previous job, a pair of sunglasses, and a pair of headphones.

Hmm... well, I suppose I can cover up all this ape-ness, head down to the Central Park zoo and see if I really can communicate with apes and such. Derek decided it was a plan, besides, if it didn't work, he got out of the house for a day - there's no way this experiment could go wrong.

Bundled on his outfit, the earphones on his ears, his arms and legs covered and his massive feet comfortable concealed from the public, Derek takes it upon himself to visit the zoo in Central Park.

As he plans, his visit there starts with the gorilla habitat. A silverback female sits in the center, grooming herself as she basks in the slowly setting evening sunlight.

Alright... now let's see if we can actually communicate with her, eh? "Hey, monkey, monkey!" Derek calls to the gorilla. There's no response, mentally or physically. The gorilla minds her own business, picking through her fur, looking around her habitat.

Nothing? Huh... that's not... what? Derek feels his stomach stirring as a strange scent passes by his nose. A strange, copper-like scent fills his nostrils as he walks around the gorilla's circular-shaped habitat.

The smell, so Derek discovers, is coming from the gorilla. She's... in heat? Why would that make me feel so... uh oh... Derek looks down, feeling his crotch tingling. This pill is doing more than just changing my face and hair... what's going on?

The smell grows stronger, teasing his cock into becoming erect. Derek leans over the bars that fence the top of the gorilla's habitat, taking in a long, deep drag of the scent in the air. He could feel his loins throbbing harder.

Shit... it's... it's that gorilla. I'm getting... horny! Looking both ways, Derek watches for passersby, noticing a lot of them leaving. A zookeeper enters the gorilla's habitat and hands the gorilla a rather copious amount of fruits and some veggies, which she gratefully accepts.

The gorilla stands, hugging the zookeeper gently, but as she stands, Derek can't help but notice her rear. Damn... that ass is... shapely, isn't it? Ugh, what am I thinking... that's a monkey! I'm a man! And... that's... a female...

The zookeeper leaves and the gorilla returns to her fruit, peeling and nibbling at the small pile. Derek doesn't hesitate to climb up on the bars, sitting on them, his erection pressing firmly against his jeans.

He hops over the habitat's fencing and slowly approaches the gorilla, "Hey there... what a pretty girl you are... you eating your fruit?"

The gorilla stops eating and looks at Derek, her eyes growing wide. She stands to her knuckles and walks around Derek, sniffing at him and looking through his clothing, pulling at his jeans and at his headphones.

The headphones and sunglasses fall off, and immediately the gorilla displays a little dance of happiness. I thinks he... knows?

_ _ "Hey, you look pretty happy, huh? Is it 'cause I look like you do?" Derek says, crouching down, his erection dripping with precum, dotting his jeans with a small, soaked spot.

"G-agh!" Derek yelps as his arms and legs begin to feel stiff. He takes off his shirt and looks at his arms - they're bulging, swelling up in the shoulders and forearm, making him look muscular. The growth is painful in both arms, throbbing as the muscles swell at this rapid pace.

The female gorilla pays no mind - she's interested in the scent rising from Derek, causing her copper scent to become more pungent.

Derek's legs swell up as well, his calves increasing in size with a painful stretching feeling, almost like a Charlie horse that won't go away. His muscles continue to grow so large that his jeans have become far too tight. The erection plus the calves' growth made the denim pants become too unbearable.

Derek takes off his clothing, tossing them to the side, relieving his body of the pressure caused by his enflamed muscles. His chest had also become thicker with muscle. Damn... I'm ripped! But I'm also really hairy... I wonder if... huh? Oh!

The female gorilla coos, gently chittering, calling upon Derek to possibly mate with her.

I can understand what she wants... but I don't hear anything in my head... this pill... maybe it just helps us to better understand what gorillas wa--oh my God!

The gorilla sniffs at Derek's cock, licking at it a few times and grumbling a low, soft grunt. Turning her back to Derek, she looks back at him and stands still.

Derek looks down at the gorilla's entrance, swollen and pulsating a bit beneath her rear end. Derek's erection springs a bit larger, leaking precum down into the grass below.

Reaching over to his jeans with his massive, primate hands, Derek reaches into his pocket for his wallet, getting a condom out of it. Opening it, he slips the condom on his hard, erect cock. Oh man, I'm actually doing this... oh man, oh man... I can't stop what I'm... aaaugh!

Derek looks down to see that is cock is balls deep in the gorilla's pussy. He instinctively thrusts, groaning under his breath. As he thrusts, his back begins to give out, swelling and arching, deforming.

While thrusting inside the gorilla, Derek becomes hunched, his legs shrink a bit as he feels his waist getting smaller, but his belly a bit bigger.

I can't... concentrate! What's going on? Oh... this feels so damn good, but... what's happening? Mmgh! I don't care... I... I wanna cum so bad!

_ _ Soon, Derek notices that the pleasure of mating with his gorilla companion is slowly ceasing. He pulls out, noticing that his cock is shrinking.

What the hell?! My dick! It's... i-it's...! Derek's cock vanishes, forming into a small pearl between his legs. What was once a cock is now just a swollen, shining, gorilla clitoris.

The female gorilla turns to look at Derek, only seeing that he's become female. Losing interest, she walks away, returning to her fruit.

"No wait! Come back...I..." the condom falls to the ground as Derek leans over, landing on his massive knuckles. Great... what else could go... wrong?

Derek feels a stinging in his stomach. He felt as though his loins and stomach were going to burst. He sits on the ground, holding his belly as the last of his facial features turn purely gorilla, leaving a painful sensation in his mouth - his teeth have changed, too.

His belly grows larger, swelling at an alarming rate. The pain becomes too much to bare as Derek rolls to his back, turning to his side and scrunching himself into the fetal position, holding his belly in his massive, hairy muscles.

Soon, the pain slowly subsides. Breathing hard, Derek sits up, sighing in relief. The pain is over, but the transformation, however, that's only begun.

In Derek's belly, a small being grows. A little fetus, planted in his newly formed uterus by unknown forces. This is what is responsible for the pain in Derek's swelling, growing belly.

Derek's heart flutters as his body grows quickly attached to the female hormones in his body. He cradles his stomach and coos gently to himself, smiling.

I guess... everything happens for a reason, huh? Derek thinks to himself, feeling his firm, swollen, pregnant belly. He looks over on the ground next to him, the condom laying, barely used. That's a shame... I really did like her!
