After one day, when she caught me masturbating twice in one day, my mother warned me that my libido would get me in trouble. Little did she know...

Before I go any farther, let me introduce myself. My name is James Doyle, I am nineteen years old, and have the typical semi-muscled surfer body from living in Southern California. I'm also attending the local community college, just to "wet my feet" a little. Like most college students I'm always in need of money, my parents are not exactly loaded but we get by enough that I don't receive any federal aid for college and my student loans all go to pay for classes and books. It sucks.

One day after class, I went down to the student center where the job board was located. I had found out from a friend that some people posted their odd jobs on the board, they paid decent money and most were one or two days long at the most. Having just put my last twenty in gas, I desperately needed the money. My parents were strict that I was to make my own money, unless it was urgent they were not lending any money. So I walked to the board and looked for the highest paying job available. There were the standard dog walking, yard work and a few medical testing flyers. I knew that the medical testing flyers were my best bet so I ran through them, one was for an insulin test and paied fifty dollars a day, gave me food and lodging for the week I would be there. It sounded good but I could not afford to miss a week of classes. There was another for drug rehabilitation, one problem though I was not addicted to anything like the other college students. Finally I came across one that sounded interesting. One hundred dollars a day, I could come and go as I pleased, required to show up for one session a day, flexible hours, the only problem was the testing lasted for ten months. Did I really want to do this for ten months? It took me only three seconds to make my decision, hell yes! They would pay me seven hundred a week, which added up to two thousand eight hundred a month! If I was accepted to this trial, I could leave my job! I grabbed the flyer and stuffed it into my bag. The flyer was fairly new, so if I took it there was a good chance there would be less people to apply.

************************************************************************************************************

The next day I drove my car down to a building with a large sign in the front that read: Theris Medical Research Facility. The parking lot was damn near full, so, much to my annoyance, I had to park at the back of a large parking lot and walk the twenty feet to the front door of the building. As I entered the door, a rather large woman with red hair looked up from her desk.

"Hello! Welcome to the Theris Medical Research Facility! How can I help you?" she was bubbly, I dislike bubbly people, and southern from the sound of her accent.

"Yeah, I'm here for the drug trials." I was wondering what they exactly entailed.

"Oh, I'll just call Dr. Ethram down for ya." She picked up the phone and dialed a number quickly. After a short conversation, she looked back up at me. "Dr. Ethram will be here soon hon, why don'tcha take a seat, he'll be a bit." She gestured to the small waiting area and I just took a seat close to the window.

Looking down at the table I saw some standard waiting room magazines. Cosmopolitan, Deer Hunting, Family Circle and... Dog Fancy? I have never seen a dog fancy magazine since we took my golden retriever Buddy to be put down at the vet's office. It brought back some happy memories, so I flipped through it while waiting. It had been about ten minutes then some one cleared their throat.

"I heard there was someone here for the drug trials; since you are the only one here I assume this would be you?" I looked up from the magazine and saw a small Indian man, wearing a white lab coat standing before me.

"You must be Dr. Ethram. Hi, I'm James Doyle; I found the flyer at the college." I tried to be relaxed but I have always been terrified of doctors.

"Good we needed another test subject, and you're lucky too. The test subject that is ending his trial today is male and we needed a replacement. Please follow me." He turned and led me down a long hall, I could hear some odd noises but I couldn't place the sound.

"Here we are room 203." He slid his I.D. badge through the lock and opened the door. "Please after you."

I walked in and saw the room was a small cubicle that was painted white inside. There was an examination table and a set of stainless steel supply closets.

"I have a question Dr. Ethram, why is the door locked?" I was a little worried, I knew they would have security but on a medical examination room?

"It is to prevent anyone from stealing supplies from my supply closets. Only my identification badge works on this door. I have some very expensive equipment in here, last thing I need is to have to replace it." He turned and opened his supply closet and pulled out the standard equipment for an exam. Stethoscope, wooden tongue depressors and a rubber mallet. "Now I must ask you if there are any diseases that run through your family."

"No," this seemed to be a normal exam.

"Any sexual dysfunction?"

That threw the "normal" part of the exam out the window. "Excuse me, what?"

"Any sexual dysfunction, erectile dysfunction, ect?" He asked nonchalantly.

"No, not that I know of." This was getting weird.

"Your heart rate in normal, your reflexes normal and if you would open your mouth please?"

I complied as normal.

"Say ahhhh."

I rolled my eyes; this was the most ridiculous part on any exam. "Ahhhhh."

"Thank you, no sign of any inflammation. Good. You have passed the exam. I believe you will make an excellent addition to the trials." He threw away the depressors and returned everything to the shelves. He turned around and handed me a clipboard. "Now be fore you sign, I assume that you would like to know what the trials consist of?"

"Yes, if you could tell me doctor." I skimmed over the form, a standard release form.

"This trial is to help with sexuality."

"Excuse me?" I was shocked.

"We are working on a new drug that helps increase desire, performance and fertility. If you agree to our terms you will be administered the drug and will return everyday to receive another dose. At that time we will also be measuring your, for lack of a better word, 'growth'. This will be phase one, phase two will be the final check of the drugs effectiveness. You may or may not father a child, but you will assume no responsibility of said child."

"So you're saying that I'll be given a sex drug and have sex?" Like most young men, this seemed to be too good to be true!

"Yes, exactly Mr. Doyle."

"Then I'll do it." I signed the form and handed it back to Dr. Ethram.

"Very good, tomorrow return and we will set up your plan. You will meet Dr. Agusto. Here give this form to Katlyn at the front desk and she will write you your first check. Welcome to the team."

************************************************************************************************************

That night after discussing with my parents the fact that I was now making my own money, leaving out the fact that I was going to be taking sex drugs and having sex- I knew mom would be the first to call me a prostitute, I laid awake in bed wondering if this was really going to be how they said it would. I just dismissed it, knowing that I was already one hundred dollars richer for it.

************************************************************************************************************

After class, I drove out to the research center and I was lucky this time to find a closer parking spot. Walking in I saw Katlyn again, she greeted me with the same bubbly mood she used last time.

"Hi hun, Dr. Agusto told me to tell you go to room 307. It's on the second floor, hall to the right."

After a short elevator ride, and a few minutes of searching, I found room 307. Opening the door, I can see that this is a conference room and at the head of the table sat a squat bald man.

"Welcome, you must be our new trial subject James Doyle. I am Dr. Agusto, head of trials. I assume that Dr. Ethram explained what this trial was regarding."

"Yes he did." I answered, but I couldn't help but blush.

"No need to be embarrassed son. It's perfectly fine. Now because you signed the form I must arrange your times for administration of the drug."

"I am a college student as you know and I need to be able to come down after classes."

"No problem James. Now I can also tell you that you can come here at any time. Unlike what Dr. Ethram told you, anyone can come and go as they please, we just need to know how dedicated you are to this trial. Now if you'll follow me, I will take you to the basement level."

After exiting onto the basement floor, I could see about ten doors lining the hall.

"Here is your I.D. badge, it will allow you access to your room, room 5. The other rooms, except room ten, are empty if you must know. The other trial subjects have left and you were the only one to apply."

"What about room ten?" I asked wondering who else could be down here.

"Room ten holds our canine test subject, a Great Dane female. She in mainly here because nobody wanted her after the animal testing were finished. She needs a good home. The only problem is that she needs constant injections of a special drug we designed to help with her pain."

"Really, that's quite sad." I couldn't help but feel sorry for the dog.

"If you'd like she could be included as part of your payment. If you are inclined to take her but we must insist that she be kept here until the trials are finished." Dr. Agusto looked at me and smiled. "If I wasn't allergic to dogs, I would have taken her."

"I will think about it." I said knowing that I probably couldn't take her home anyways.

Dr. Agusto slid the I.D. badge, then handed the card to me, and opened the door. Inside the room was painted the same stark white but this room included a small bed with white sheets and pillows, a stainless steel supply closet, a small ledge running along the wall next to the bed, and a closet with glass doors that allowed me to see the vials and bottles in it. There was also a small metal tank sitting in the corner of the room.

"What is that, if I may ask Dr. Agusto?" I pointed to the small metal tank.

"That is for the first part of phase one. Now don't be embarrassed but I need you to strip naked and get into a comfortable sitting position on the bed."

"Excuse me?" I was a little startled.

"We need to harvest some of your sperm to freeze for future use; there is a five percent chance that after this trial you may become infertile. So as a precaution we have begun harvesting sperm, we will send them to a storage unit so that if you do become infertile you can still have a child. Please, strip."

I reluctantly began to strip; it was embarrassing to do so in front of another man. I was down to just my boxers and I looked up at him.

"I do need you fully nude. In addition to gathering your sperm, I must measure your penis both erect and flaccid. A side effect of this drug is that some experience penile growth."

I looked at the doctor, then after gathering my resolve, took my boxers off.

"Let me begin before you make yourself comfortable. Let's see here, ah four and one-half inches in length, one-quarter inch in diameter. Now you can make yourself relaxed on the table." Dr. Agusto then picked up a clipboard that was hanging on a hook on the door and wrote down my measurements. "Now I will need you to hold still while I manually stimulate you to a full erection."

I just let my moth hang open; he was going to touch my cock! Nobody other than me had touched my cock in that manner, let alone another man! All doubt in my head was banished as he began slowly stroking my cock. It felt good, better than when I did it myself. Within three minutes my cock was as solid as steel.

"Okay, let me measure. Six and one-quarter inch in length and one inch in diameter. Alright let me write this down. Alright the next phase will be more pleasurable for you." He went to the supply closet and pulled out an odd contraption. It had a six inch soft plastic tube that was about two inches around with a slit-like opening, this was connected to a hose with was connected to a part that was connected to a large test tube. "This device, when turned on will milk you of your sperm and deposit it into the test tube. We will do this multiple times until you cannot produce any more sperm, and of course I will change the test tube in between milkings. Let us begin."

Dr. Agusto laid the device beside me and sat it on the ledge. He returned to the supply closet and pulled out a test tube rack holding twelve test tubes, he then brought the tank closer and loosened the lid. Then he returned to the supply closet and brought a tube of lubricant. He opened the tube and began to rub the lubricant down my hard shaft. He then grabbed the device and began to place the tube over the head of my cock. Even with the lube, the fit was tight. I could barely hold myself from cumming right there! Then he pushed the button on top of the device, there was suction and the sides of the tube were contracting and pulling on my cock. If this is what a pussy felt like, then I couldn't wait for phase two. Just then I arched my back and unloaded my first load of cum, firing it out of my pulsing shaft into the awaiting test tube. He pushed the button again and pulled of the test tube with an audible pop.

"Very good for your first time." He held up the test tube and I could see it was filled to the fifty milliliter mark. "Quite large for most men, hell you could have been a porn star and forgot college!" He gave a rich deep laugh. He put a top on the tube, opened the tank, reached in with a pair of tongs and brought up a tall metal rod surrounded by metal rings with holes big enough to hold test tubes. Carefully he placed the tube into a slot then lowered the rod back into the tank and placed the lid back on.

Over the next hour, Dr. Agusto milked twelve tubes from me, each holding about fifty milliliters each. I was on my thirteenth, the pulsing, pulling and milking motion of the tube on my cock was pushing me over the edge and I felt my cock pulse but both I and Dr. Agusto saw no sperm in the test tube. He had milked me dry!

"Very good, not many people can produce twelve tubes, most produce five to seven at the most. You really could have been a porn star and made good money!" He laughed that rich laugh again. "Now while you are still naked we will administer your first shot. This shot is a fluid designed to increase sperm production and potency. I will show you how to do it the first time, from then on you will proceed to do this yourself. You'll begin by injecting one hundred ccs into each testicle. No more, we don't know what would happen." He got up pulled out of the glass door closet a small vial labeled composite X-7986 and a disposable needle in a plastic wrapper. He showed me how to draw out one hundred ccs and where on my sack to inject it in both sides. There was a slight pinch, then a burning feeling that soon gave way to a cool feeling, as if a spring breeze was blowing across by balls. He returned the vial and came back with a plastic bottle labeled composite Y-97. "Now here are the tablets you are to come in and take three. Make sure you only take three, more could leave you in a lust crazed state." He handed me the tablets and went to the supply closet. He showed me the mini fridge at the bottom that held small bottles of water and tossed one to me.

"So is that all there is?" I asked after swallowing the tablets.

"Yes, you can come anytime day or night to receive treatment. Just be careful not to treat yourself twice in a twelve hour period, this can have unexpected results."

"Okay, got it no injecting or tablet taking until twelve hours have expired since the last treatment."

"Good, now James if you would allow me to leave, you are free to stay here as long as you wish. Oh and your I.D. card will allow you to open the other rooms, so you can visit the dog if you want." He winked at me then said, "There is even a leash if you want to take her for a walk. She doesn't really get any exercise other than a walk every three days."

After he left, I went down to room ten and slid my card. The door unlocked and as I opened it, I was knocked down by a large chocolate brown Great Dane that was licking my face like crazy!

"Easy girl!" I finally was able to push her off of me and she sat down staring at me. I moved my hand to her and began petting her; she wined and started to curl up next to me. I looked and saw that she had a collar. The collar clearly stated subject Day-17Z, huh she never had a name. No wonder Dr. Agusto called her "the dog".

"Well I'm not going to sit here and call you 'dog', how about... Daisy?" I asked her while scratching behind her ears, just like Buddy liked.

She cocked her head to one side then woofed. It was deep and she seemed to be saying she liked it.

"Okay Daisy it is. How about a walk?" As soon as I said walk, she trotted over to where her leash was hanging and pulled it down. She then dropped it in my lap. She knew what she wanted.

************************************************************************************************************

Later that night while lying in bed I thought of the day. Katlyn the receptionist had told me that she normally walked Rose, as she called her but was soon corrected that the dog's name was now Daisy, and was glad to see someone else caring for her. Daisy loved being outside and when I took her to the dog park; she ran around and barked like crazy. I couldn't believe how much I missed having a dog. Now I had one that my parents didn't know about and after the trials she would be mine permanently.

************************************************************************************************************

After the first week of treatments, I begin to feel odd. I was constantly horny, I masturbated three times a day, and I notice my cock and balls were getting larger. My balls use to be the size of large walnuts and now where the size of large hen eggs. My dick had increased to being six inches long and one inch thick while soft, as big as I use to be hard! Now when I was hard, I was nine inches long and two inches thick. Whenever I masturbated I now had to make sure my cock was covered. The first time I masturbated with my new cock, I blew a load all over my parent's bathroom. That was a pain in the ass to clean up.

Also during this time I have become closer with Daisy. I walked her every day and even began to help give her injections for pain. We would go and play in the dog park everyday. I couldn't wait to be able to take her home.

************************************************************************************************************

Half-way through week two I notice something weird. Every time I was with Daisy, I smelt an odd smell. It was if my nose had kicked into overdrive. It was when I first smelt this, that I accidentally injected myself with double the normal dose. I realized it after looking down and saw the plunger was at two hundred ccs. What else could I do, I decided to do the same to my other testicle, what could happen? When I went to get the tablets, I figured that I'd take double as well. In for a penny, in for a pound, as mom always said.

After double dosing myself, I went to take Daisy for a walk as normal. When I opened the door, I was assaulted by the scent I smelt earlier. I realized Daisy was in heat. I couldn't take her for a walk, she might get knocked up. I walked over to the closet and pulled out her injection vial and read that they had changed the formula given to her. It now read KY-97, it sounded so familiar. I injected it into her and for the first time she just sat there and began whining. So I just sat there and pet her, but soon that became too much for me and I had to leave, the smell of her heat was turning me on! I told Daisy goodbye and ran immediately to my own room. I went in, slammed the door, immediately stripped and jumped on the bed. My cock was a raging pillar of hard, throbbing man meat. I couldn't help myself and began jerking hard and fast. Soon I let out an animalistic howl; my back arched and shot a load of cum all over my chest. As I lay there breathing in shallow ragged breaths, I realized I was turned on by Daisy and that that was the best orgasm I had ever had!

************************************************************************************************************

During week three, after having so many strong orgasms from walking Daisy, I began to inject myself with four hundred ccs, and was taking twelve tablets. I figured with summer vacation just starting, I could just stay here at the center and no one would notice my obscene erection.

I had gained permission to stay at the center for the final months of the trial, and told my parents I was going on vacation in the mountains, so everything was going great. I had saved up in my bank account the fourteen hundred plus dollars I had been paid. I figured after saving up the money I'd use it to move out of my parent's house into my own apartment with Daisy.

It was when one morning that I had awaken with my super hard morning wood that I smelt that smell again. Daisy was in heat again, and in some animalistic part of my mind I wanted her, I lusted for her. So I got out of my bed and walked into the hall, checking both ways for anybody that could possibly show up. Normally nobody came down here, but I had to be safe. Seeing that it was clear I unlocked Daisy's door and she got up to greet me. I was bombarded by the scent of her heat.

"Come on Daisy, you're coming to stay in my room." I said lustily. She then whined and woof in appreciation.

Quickly we went into my room and I sat down on the bed. Daisy then jumped up next to me. I wanted her right there but I didn't want to force her. My thoughts were interrupted as I felt a lick on my balls. I looked down; Daisy was whining and licking my balls. I leaned back in pure pleasure as she began to slowly lick from the base of my cock to head. She was licking it so hard that I was getting harder.

Soon I felt like I was getting close, I pushed her back and she whined. Slowly I moved my hand down to her pussy, it was warm and wet. Slowly, I entered my finger and began moving it. Daisy immediately began pushing back against my invading finger, soon her pussy clenched and unclenched around my finger. Her tongue was hanging out of her mouth and then she turned around, raising herself to me.

I then dove in head first, having never eaten pussy before, and began to lick her puffy, warm pussy lips. She tasted of grass and earth, I began to dart my tongue in and out slowly. Then as she began to whimper, I picked up speed and was tongue fucking her. She was thrusting hard back against my face, and then suddenly I tasted her warm juices in my mouth.

She remained with her front legs down and her tail rose. I didn't want to hurt her so I went to the closet where my treatment medication was kept and brought out the lube I kept there. Daisy whimpered and whined as she watched me slowly lube my rigid cock up. Then slowly, I got on the bed behind her. She looked back at me and wiggled her rear as if saying 'come on fuck me'. I slowly lined my cock up with her pussy and began to slowly push my cock in. She was so fucking tight. Daisy gruffed and began to push against me. I was losing my virginity to a dog, but I loved her. Suddenly, I felt my cock stopped. I couldn't have bottomed out already; I looked down and saw five of my nine inches still not in her. Daisy began thrusting and whimpering hard. Then I realized it, she was a virgin too! I placed my hands gently but firmly on her sides. She kept trying to thrust onto my cock. Then I withdrew till just my head was in her, then with a hard thrust I felt myself break her barrier. Daisy let out a howl and became rigid. I was worried that I might have hurt her. Then she started to slowly thrust against me. Her velvet warmth was tugging on my cock. I couldn't take it any more and began to thrust into her, soon I bottomed out. It was heaven feeling every inch of my cock in her tight pussy. I began thrusting slowly in and out. She matched each one of my thrusts and soon we both began to pick up the speed of out thrusts. I felt myself getting ready to cum, I thrusted faster and soon Daisy let out a howl and it felt like she was going to rip my cock off. She gripped down so hard, with one last thrust, I hilted myself against her and let out the torrent of cum. I let out a howl to match hers and collapsed on her back. I held onto Daisy and rolled both of us over, making sure that I was still inside of her, soon we were both fast asleep.

************************************************************************************************************

The rest of the first month continued in the same way, I was overdosing myself and fucking Daisy every chance, I got. It was a perfect for me.

One day after I had just fell asleep, still hilted within Daisy. I was awoken with the deep sound of someone clearing his throat. I rolled over still buried in Daisy to see Dr. Agusto! I turned five shades of red with embarrassment.

"Don't worry boy, I'm not going to ruin your fun. Actually you're doing exactly what phase two was supposed to be. I was suppose to induce the dog, or 'Daisy' as you've come to name her, into heat and leave you in the room in a lust crazed state until you bred her. To tell you the truth we've been watching you, since you began to overdose we thought this might ruin everything. But when we realized that you were already breeding her, we knew it was safe."

"Wait, I was supposed to end up with Daisy after all? What kind of sex drug is this?" I had so many questions but Daisy began stirring and I was getting hard again.

"It is for zoophiles specifically. We are planning to market it online. We know for a fact that people would pay large amounts of money if they could fuck and have 'children' with animals." Dr. Agusto said with a pretty even voice.

"So that means Daisy will have my puppies or children?" I was confused.

"Well the female testing went well, all women who took this drug successfully gave birth to live litters of whatever animal they made love to. One woman even successfully gave birth to a Shetland pony. The male testing has been having some major issues. It is hard to get sperm to become to vast in capability to fertilize any animal. We will hopefully have success with you and Daisy. I'm going to take her away for a little bit... maybe after you've finished." He let out a low chuckle as he saw Daisy grinding against me.

He left the room and waited until the howls died down. He left for maybe half an hour, I was beginning to worry about Daisy, and then he finally returned with her.

"Well, what'd go on?" I asked worried as Daisy trotted over to me.

"Well it all good news, the test was a success you successfully impregnated Daisy and we can begin marketing immediately. Now you just need to remain here for the next nine months until Daisy delivers."

"I thought dogs had a short time until birth?"

"Well the problem in the human sperm and eggs still need the time to develop so Daisy will give birth in nine months. Plus, I don't think you'll deny the extra money."

************************************************************************************************************

It's been ten months, Daisy has had her litter and they genetically tested as pure breeds. We sold the puppies off once they grew big enough. Not to mention that the drugs Daisy had been injected with keep her in a constant heat, so I'm never without sex. As a bonus besides paying me the money, the facility has assured that I will continue receiving ZooLove, as they are now marketing the product, for the rest of my life. Also they gave me a house on the beach which is fully paid and insured. I have also been permanently hired by the facility doing clerical work, mostly filing paperwork. I had found a surrogate and now also have a son on the way. Daisy is also expecting her next litter; both my son and litter will be born on the same day. I live a perfect life, and it can't get any better!
