It started one day when I visited my gynecologist for my annual check up. As I sat there waiting for my appointment, I noticed on the table there were the usual stuff on regular pap smears and breast examinations etc. There was also a small leaflet asking for women to help with a study a local clinic was doing with a university. It went on to say you would be paid for your time and it was only for 3 six hour sessions over 3 weeks. It had a number to call for inquiries, so I took it down and thought why not at least call and ask how much was to be paid.

Once I left after my appointment, I thought why not call and ask. I rang the number and a woman answered, I said I was calling in regard to the leaflet I had seen. She went on to inform me that the participants would receive $ 600 per session. I asked what exactly was involved, she went on to explain that it was mainly a study on female sexuality regarding women's arousal patterns and such.

She went on to say it was mainly a lot of questions and a few clinical examinations and if I had had a pap smear I would not be any worse than that.

I agreed to come in and at least look into it further as I really could use the money.

A week later it was time for my appointment, as I got ready I wondered what should I wear. Deciding on a skirt and top I had recently bought along with a matching bra and panty set. On entering the clinic I noticed there seemed to be very few people around. I approached the desk and the young woman said oh you must be Emma we have been expecting you. Come thru here and I'll have you met doctor and he will explain everything to you. Within a few minutes this gorgeous doctor came in, he looked to be in his late 20's. He introduced himself as Dr Jones. He explained about the tests etc they were doing and asked if I was sexually active. He went on to ask why had I replied to the ad. I explained that I was curious when I read that we would be paid and how I really needed the money at the moment. He suggested that I may be interested in some further studies that they were conducting as well, as these paid almost double the rate of the 1st ones. However they were to be a little more intrusive that's why the rate was a lot higher. He said that any woman that was sexually active would be fine with them and everything was to be kept strictly confidential.

I thought about it, and thought what the heck no one will know me, I really need the money and it is confidential. It meant that for 3 or 4 days tests etc I could get almost $ 4,000. I agreed to go ahead with it, they had me sign a whole lot of forms etc, and I was asked if I wanted to begin today. I had nothing else on so I agreed.

I was taken into a large room where I was asked to undress and put on a gown.

Then they performed a medical check taking all my details blood pressure heart rate etc. I was given something to drink which I was told would help with the tests. I was then asked to hop onto a bed and had various things attached to me, to monitor heart rate etc, things on my head to measure brain activity, pad things were attached to my breasts and others to my legs. The doctor along with his nurse then told me to relax and just think about a series of questions they were to ask me. I was asked a lot of questions some which were really explicit about my sex life. They then had me watch some films etc monitoring my responses to various scenes. The whole time taking notes and video taping the whole thing.

After several hours, well it felt like several hours anyway. The nurse said she had to just give me a small shave and tidy up for the next session. When I asked why we had to do this she went on to explain that if I didn't finish the tests I would receive none of the money and in the consent forms I had already consented to let them do this. She reminded me of the amount of money I was to be paid. Ok sorry I said if you have to go ahead. I was moved down the bed and stirrups pulled out with my legs put in them. I felt her begin to shave my pubic hair, of which I had little anyway. She left for moment and returned with the doctor and I was given an injection which they said was part of the tests. Good the doctor said at least now she wont complain so much, what was I given I asked to which I was told just something to relax you don't worry Emma.

I began to feel a bit groggy sort of but really relaxed. When they both returned I Had my legs tied to the stirrups along with my hands so I couldn't really move.

The nurse then wheeled over a tray thing, I couldn't see what they were doing however I soon felt something being put inside my vagina. I was told it was to measure my arousal as we continued to do the tests. See she is already reasonably aroused said the nurse to Dr Smith. I was then shown various scenes and they took notes. Some were really really explicit with women having sex, or being gang banged or tied up and having various things done to them. This went on for ages before they said yes I can see a pattern, can you nurse Jones ?

I was told to relax and have a rest today's session wont be much longer. I must have fallen asleep because when I awoke I was in a bed and it was five hours later. The nurse came in and said get dressed Emma your done for today and we'll see you in two days for the next stage of tests ok. I got dressed and went back outside and was given a cheque for $ 1,000 for today. As I left I thought god I feel a bit funny, but looked at the money and thought oh for $ 1000 I don't mind this. I was given two tablets which I had to take 4 hours before my next appointment.

Two days later I got up showered, did my hair and make up. I put on a lovely almost see thru blouse with matching bra and panty set. I had shaven my legs and private parts as requested. I was ready to go and on the way I felt anxious, a little nervous of what was to be done to me I guess. As I walked in the receptionist looked up saying oh your Emma right, go thru to room 3 and the nurse will be right with you my dear. This room was different to the one I was in last time, it seemed to have a lot more equipment in this one. The nurse came in and asked me to put on the gown supplied, checking to make sure I had taken the tablets as instructed. Once in the gown the nurse returned and had me sit on the bed and began to ask me more questions. She had me watch a thing on the wall and listen to some music, explaining she was going to put me under hypnosis to relax me and make me feel better.

The doctor walked into the room, asking the nurse if I had taken the tablets and was under yet to which she replied yes doctor she is ready for you to begin.

I was told to lay back and relax as they connected there things to me to monitor my reactions and arousal once again. I had the pads and things on me all over, I had something once again put inside me and this time I felt small clamp things on my labia. As the doctor spoke to me I felt so at ease, he began asking me a series of questions. Some about previous things I had done sexually, which normally I would not have told anyone, however I told them everything.

I was asked about sexual fantasies and given different scenarios to think about.

The doctor turned to the nurse saying ok we can proceed to the next stage now, I believe we have a lot of the information we need. I felt like I was in a daze laying there feeling all sexy and hot knowing they had me really aroused. Not knowing if it was from the drugs, the hypnosis or the questions we had been talking about. I felt my legs being opened wider in the stirrups, then something being pushed inside me. The nurse said its ok dear it wont hurt at all just relax.

It felt like a toy or something and in no time the doctor said there that's it relax now Emma. I had something attached to the hood of my clitoris and my nipples as well. They put some goggle things over my eyes and a mask over my face.

They told me to relax, I was going to be taken to some of my fantasies.

I was in a gorgeous long black dress sitting at a dinner table with all these people. We were drinking expensive champagne and eating lovely food. The room was so beautiful with marble and gold everywhere. I was surrounded by the most beautiful people I had seen, some men some women. The man to my right was so big and strong looking, a dark man maybe a professional sportsman or athlete. To my left was another man also so handsome and huge. There seemed to be equal numbers of men and women, the men all dressed in suits and the women in the most beautiful dresses and gowns. As everyone finished there meals maids came out and removed all the plates etc. Once this was done a gentleman at the end of the table stood up and announced it was time to begin. He said everything had been arranged and once your name was called a room no would be given and the women were to go directly to there assigned rooms. A few names were called and the respective women got up and headed off to the rooms. Emma room 5 the man called, I stood and thanked the people near me, walking down the hall to room 5.

As I entered the room I saw one of the maids standing there, Emma come over I'm Natalie and I'm here to help you and get things organized for you. This is one of your fantasies about to happen. Remove your dress and lay down, I'll start with a massage for you. I laid on my tummy as I felt some hands begin to massage me, then another pair and another. Before long I had 3 men and Natalie all massaging me and touching me all over. I was being kissed all over, my neck, my ears, my legs. I was so hot so sexed up as they had me turn over, the man I had been with at dinner was kissing me, while another was suckling my breasts, another kissing his way up my legs. I felt that wonderful feeling on my pussy as my lips were being sucked, my whole pussy was so hot so wet. I felt a tongue being pushed into my wet juicy cavern of womanhood. My nipples were being pulled and sucked on, my face had a pussy being lowered onto it. Natalie was sitting on my face as I was being licked and played with myself. I felt my legs being lifted slightly and pushed open wide. Then I felt something being rubbed along my sweet wet lips. It was the dark man I had sat next to at dinner.

I felt my pussy open as he eased himself into my pussy, slowly slowly inch by inch he entered me. He must have been huge as I felt myself being stretched being forced open more than I ever remember. It felt so wonderful so sexy, to have so many hands and things playing with me using me. I felt the dark man pounding into my wet pussy like I have never had before, my clitty being ground against his pubic bone as he slammed into me. Then I felt him hold me tighter for a moment as he grunted into my ear, I knew he was cumming deep inside my little white vagina. I could do nothing but accept his seed as I felt the hot juice squirt in me. He got off me and before I could do anything another guy had replaced him, pushing his hard cock straight into me to the hilt. I felt his balls on me as he was all in me. I just lay there Natalie now kissing me as I was fucked by another guy. He came in me also, I could feel all the cum leaking from my swollen wet pussy.

As he finished another guy jumped on me, another black man with a huge swollen cock. I felt my pussy stretch a little as he pushed himself into my now soaking wet pussy. Natalie whispered into my ear wait till you see the size of the cock in you now, it will amaze you Emma. He must have been big because I don't think he was all the way in me, and I felt stretched and sore. He said I'll give you a minute baby so you get used to it before you get it like your never had before. Natalie said don't worry you'll love it, as I felt her fingers move down and feel him in me and play with my clitty.

Then I felt it, he lunged forward slamming the rest of him into me, I screamed as he pushed so far inside me like no one had ever been before. I lay there gasping, feeling like never before as he pumped in and out of my sex.

I felt my whole body go into convulsions as I came, I could do nothing but ride the huge waves of pure pleasure that washed over my body. I felt him tense up knowing he was going to cum deep in me, spraying his seed deep into my womb. Then I felt his hot cum spray my insides with his man juice all over my vagina.

The men left and Natalie helped clean me up.

Ok the doctor said to the nurse, I think she has been through enough today. Emma wake up dear we are finished for today. As I looked down all the bed was wet, actually soaked beneath me there was even stuff on the floor next to the bed. How do you feel the nurse asked me, oh I don't know really I said can I rest for a bit before I get up I feel a bit funny. That's normal really do you normally squirt when you orgasm she asked. No I have never why? Look at it yes you do Emma. These tests show us a woman's real capacity sexually and as you can see a lot of women don't really know what there capable until they have tried some of there fantasies. That was only your first dear we have several more for you yet.

Part 2 soon
