Tina has been a nurse for the past twenty years. She had just turned 45 and had been happily married to the same man for the past eighteen years. She was the sweetest person you ever wanted to meet as she would always volunteer for a number of good causes. She loved being a nurse and appreciated all the times that she had helped someone out.

She also had another passion inside her and that was volunteering for health related studies at the hospital. Her hope was one day reading how one of the studies she was involved with ends up making a difference in someone’s life. Tina had been involved with a half of a dozen of these kind of studies in the past and had worked closely with Dr. Gundy.

Dr. Gundy had a new study and had put out the word that he was looking for a middle age woman for his next project. Tina immediately let it be known that she was interested even though she had no idea what would be expected of her. This showed what kind of person Tina was as she volunteered before even knowing what the study was all about.

It had been a few weeks later when Tina hadn’t heard anything from Dr. Gundy about his study. She had become concerned enough that she decided to stop by his office one night on her way out of the hospital. She had done several projects for him in the past and thought she was more than the perfect candidate for his upcoming study.

“Hello Dr. Gundy. I was wondering how your next project is going. Do you have a volunteer yet?”

“No Tina, not yet.”

“I just wanted to stop by and tell you personally that I am available. It sounds like I might be a perfect fit for your upcoming study.”

“You are Tina. I got to say you are by far the best person available for this project, but you might want to hear about it first before volunteering for it.” Dr. Gundy responded back.

“Why? What does it involve?”

“Well, it is a study on the sexual works of a middle age woman. It consist of finding out why some women are more sexually aroused when they are in their forties then when they were back in their twenties. It also consist of a new drug study that helps with women who need that extra sexual boost. There are a few other elements also to this project but I can’t go into them at this point. I know you are perfect for this study, but I am looking for a woman who can have sexual intercourse with another man. I didn’t think your husband and you would be too comfortable with this arrangement so that is why I didn’t contact you,” the doctor finally finished up with.

“I am still interested. I know if it is for science or health my husband will be more than understanding.”

“Why don’t you go home and talk it over with your husband first. If you are still interested in the morning come by and see me.”

Tina went home that night not really thinking straight about what the study detailed. All she could think about she was the possibility of helping out other women down the road. She knew of friends and family that have gone through some of these exact problems. She knew she had to be part of this study.

That evening she sat down with her husband and said, “I talked to Dr. Gundy today. Remember that study I was talking about volunteering for? Well, he said it is mine if I want it. There is just one caveat though, it is a study on the sexual health of a middle age woman. He said if I want it I will need to have intercourse with another man though. How would you feel about that? I know you support me with the studies I have done in the past and I really would like to be part of this one also.”

“Intercourse with another man? Are you sure about doing this?” her husband Mark responded back.

“Yeah, I am sure. I know I can keep my private life separate from the study. I really do want to be part of this.”

“Well, I guess if you are ok with it than I will support you on your decision.”

“Thank you honey! I love you so much!” Tina said to Mark as she gave him a long hug and a kiss.

The next morning Tina stopped by Dr. Gundy’s office on her way into work.

“Hello Dr. Gundy. My husband and I talked about your study last night and I decided I want to be part of it.”

“That is great Tina! You are at that perfect age I was looking for and you are in perfect health,” Dr. Gundy responded back.

“So I got it?” an excited Tina said.

“Yes, you got it. I will talk with you later in the week as I want to get this going as soon as possible.”

Tina was extremely happy as she left Dr. Gundy’s office that morning. She knew she was a perfect fit for the study as her 5’6 and 120 pound body was in prime condition for being forty five.

It had been a few days later when she once again sat down with Dr. Gundy. He went over everything with her including checking all of her vitals. She would need to keep a diary for the next thirty days as she is supposed to keep track how she felt each day. He really wanted to know how aroused the pills were making her. She also was told that sex with her husband was forbidden for the next thirty days. She knew Mark might not be totally happy with that aspect, but she knew he would get over it soon enough. It was only for a month and not for a longer period of time.

The doctor then handed over a bottle of pink pills to her and told her to take one of them once a day. Then in one month she would start the second phase of the study. This would be the phase that she would need to have intercourse with another man so they could see how well the medicine was working.

Tina took one pill a day as told as she felt weird sensations come over. She never had a problem with her libido before and now it was off the charts with arousal. She did everything possible to improvise to keep her from thinking about sex. By the time the thirty days had passed Tina felt so much arousal flowing through her that she no longer could think straight anymore. She was more than ready for the next phase of study to start.

“Are you ready Tina for the next phase?” Dr. Gundy asked her on the thirtieth day.

“You can’t believe how relieved I am that the thirty days are over with.” Tina responded back.

“Well, your wait is over with. I want you to come back tomorrow afternoon for the next phase. This is the phase were you are to need to have intercourse with another man. Your husband is welcome to watch if he wants to.”

Tina’s husband wasn’t about to miss this as he agreed to accompany Tina the next day. The next morning Tina showered and got ready. This would be a big day not just for Tina but also her husband Mark.

That afternoon Tina went through a final examination before heading for the next phase of the project. The study was set up in the back wing of the hospital where it would be secluded and private. Tina and her husband Mark walked slowly to the room. It was a decent size room with a one way mirror on one of the side walls for medical students and her husband to observe from. A bed along with medical equipment were the only things inside the room as Tina made her way in and got comfortable.

A few minutes later Dr. Gundy and a nurse assistant walked in. He joked around with Tina, “I know this isn’t a 5-star hotel but it is all we got.”

“Alright Tina are you ready to start?”

“Yes doctor.”

“I need you to take off all of your clothes so we can put some of these wireless probes on you.”

Tina began to remove her clothes in front of the doctor and his assistant.

Her husband was in the room next to hers watching through the one sided mirror along with six other medical students. It would be there job to take notes and give their own personal thoughts to what they see.

Tina’s body was extremely nice as she got down to just her bra and panties. She then removed her bra and then slid her panties to the floor. She looked extremely sexy as her tits stood firmly out while her ass was perfectly shaped.

‘Ok Tina, we are going to put a few of these wireless probes on your body. We need to check your brain waves along with checking your heart rate. We want to see how powerful your orgasms are.”

As soon as the assistant was finished putting the small probes on her the door to the room suddenly opened. It was a young hunk around the age of twenty five as he walked in with just a towel draped around his waist. His body was immaculate as he had to be around 6’2. He was more on the muscular side as Tina stood there with her mouth practically wide open as the young hunk removed the draped towel from around him. His cock was enormous in size as it hung several inches own in between each of his legs.

“Are you ok Tina?” the doctor quietly asked.

“Oh yeah, I am ok,” a nervous Tina replied back.

“There is another part of this study I couldn’t tell you until today. It also consist of seeing if a woman orgasm is heightened by the size of a man’s cock. This young lad’s cock is around ten inches so I am hoping you can handle it.”

“Oh wow! I guess I can.”

“Well, let’s start then. I need you Tina to get on the bed so the young man can stimulate her vagina with his tongue.”

Tina got up onto the bed as the young stud moved his head in between each of her legs. His tongue was long as he began to glide it over the clit of Tina’s aroused pussy.

“Oh god! Oh god!” Tina cried out as the young man continued to glide his tongue across her swollen clit.

Several minutes later Tina’s body was squirming about the bed as the young man had his long tongue buried deep inside her. Her hands held tightly onto the back of the young man’s head as her orgasm was close at hand.

“Oh my god!” Tina cried out seconds later. She no longer could take it as she began to go over the edge. Her orgasm was so intense that her body rock the bed as she came hard all over the young man’s mouth.

Tina lay there still trembling as the young man now knelt in between each of her legs. He had positioned his extremely large cock up against Tina’s swollen pussy as he began to work it inside her. Tina immediately let out a shill of a cry as she felt the head of the young man’s cock split the swollen lips of her aroused pussy.

A few minutes later the young man had pushed four or five inches of his cock into Tina’s vagina. She was now in over her head as the young man began to fuck her with more vigor.

“Oh god! Oh god!” Tina cried out as she felt the young man’s huge cock penetrate in and out of her swollen pussy.

Tina began to orgasm hard just minutes later as she felt a huge sensation come over her. She had never cum that hard ever before as the young man slowly had worked six plus inches of his cock into her. That was all Tina could take right now as the young man gave it to her good and hard for the next ten minutes or so. It was then that they changed places. Tina was now on top on the young man as she slid her wet pussy down onto the shaft of his young big cock.

“Oh wow!” Tina shouted out as she sunk down onto about six inches of his big cock.

“Tried to take more of it?” Dr. Gundy said to her as she was able to take on another inch of it.

Tina was now able to go down on several inches of the young man’s cock. She fucked him good and hard as her husband Mark watched with a stun look from the room next door. It had been a good ten minutes later when Tina was again on the verge of a powerful orgasm. She had taken in about seven or so inches of the young man’s cock into her pussy when she began to cry out into another very intense orgasm. Her orgasm was very powerful that her chest fell down onto her young lover’s chest.

“Try it from behind!” the doctor shouted out a few minutes later.

Tina got down onto all fours on the center of the bed. Her round gorgeous ass hung high into the air as the young stud got in behind her. He slowly worked his cock back into her as Tina once again let out a loud cry.

Several minutes had passed as the young man gave it to Tina good and hard from behind. He had pushed almost eight inches of his cock deeply into her as the doctor said to him, “See if you can get her to take all of your cock.”

“Can you handled it Tina?” the doctor then asked.

“I think so! Oh god!” Tina quickly cried out as she felt another inch of the young lad’s cock penetrate deeper inside her.

She quickly felt another explosive orgasm coming on as the young stud tried to work that last inch of his cock deeply into her. Her face was plastered against the sheets while her hands were tightly wrapped up in a ball. He then gave her one last thrust as he had slid all ten inches of his cock deep inside her aroused pussy.

Tina’s head began to spin as she felt one of the most intense orgasms of her life coming on. She felt her young lover pound all ten inches of his cock hard against the back wall of her vagina. This pushed her over the edge as she screamed out into an earth shattering orgasm. She had never had an orgasm of this magnitude ever before as her body shook and trembled hard on the bed.

“Are you alright Tina?” the doctor asked as Tina’s body still quivered minutes later.

“I am ok!” a worn out Tina said back.

The young man continued to pound his big cock into Tina from behind as she was quickly on the verge of another very powerful orgasm. Then seconds later Tina again cried out into another very intense orgasm. It was on the same magnitude as the last one as her whole body went lymph. He continued to pound his cock deep into her for another twenty minutes or so as Tina again screamed out into another earth pounding orgasm.

She no longer could stay up on all fours as her body crashed harmlessly down onto the bed. The young man continued to grind his big cock into her for another few minutes before he began to moan out. He yanked his cock from Tina’s enlarged pussy and began to explode hard all over her beautiful ass seconds later.

Tina laid there still collecting her thoughts for several minutes as Dr. Gundy said to her, “You did fantastic Tina! We got some really good data today.”

It took Tina some additional time to recover as she got cleaned up and dressed. Her husband drove her back home that day as her pussy was extremely sore and stretched out. Her husband then asked her, “Was it all worth it?”

Tina paused for a second before answering back, “Yes, it was all worth it. If it helps out just one woman down the road then it was well worth it.”

A few days later Dr. Gundy went over the results with Tina. He was extremely happy with the data they had collected. He then asked Tina, “How would you like to do the third phase of this study?”

Before the doctor had finished talking about what the third phase detailed Tina already had spoken, “Count me in!”

How many husbands out there would love to see their wives do a study like this? Or even better yet how many middle age wives out there would want to be involved with a study like this one. I would be very curious to hear your comments.
