Tina was one of those special people in the world who loves to help others. She had been a nurse for more than twenty years, and at age forty five, still volunteered for a number of health related studies. It had been six months since the last time she had volunteered for one of these studies. It was a sexual health study of middle age women. The idea of the study was to see if women were more or less aroused when they hit middle age. The study involved Tina having sex with a young man, who had a ten inch cock. They wanted to see if a bigger cock really gave women better orgasms or not. The study also included a new drug that helps women get more aroused. Tina and her husband Mark, who had watched on with several other medical students, were amazed how aroused Tina had gotten that day. Tina came several times, while taking on the young man’s huge cock. The study was quite a success, and Dr. Gundy now had more money to push on with more of his studies. It took him years to persuade the board to give him the necessary funds to complete what he had thought was a viable cause. Dr. Gundy had been searching for another participant for his next study. This study was a bit unusual, and he couldn’t divulge to the potential participants what it involved. If they agreed to do the study, they would be under his control, and would be required to do whatever he asked. Dr. Gundy had received a number of interested responses, but so far no one fit what he had looking for. When Tina heard this, she immediately volunteered herself for the study. Dr. Gundy knew Tina would be a perfect patient like all the past times before, but this was a different type of sex study. He didn’t know if Tina would make a good fit or not. One afternoon Tina pleaded with Dr. Gundy, “I know I can be a help.” “Tina, you have no idea what this study consists of. I can’t go into great detail because it is very secretive, but I know you, and I wouldn’t want to see you do something you normally wouldn’t do. Besides that, your husband Mark can’t know a thing, and he won’t be able to be involved like the last study. bahçesehir escort ” “But Dr. Gundy, I know I can do it, and you desperately need someone. Please give me a chance!” Dr. Gundy sat back in his chair, and thought it out for the next few minutes. Tina was right, he so far didn’t have a worthy candidate for his study, and he knew Tina would make a perfect fit for it. “Alright Tina, if you want to volunteer for this phase of the study then I will count you in, but remember your husband is not to know, and trust me, this study is very different from the last one. I need you to take home this survey and fill it out. I need it to be filled out truthfully.” “Thank you Dr. Gundy! I know I will make your study a positive success.” Tina replied back. Dr. Gundy then made it clear to Tina that she would need to do whatever is asked of her, along with taking a stronger amount of hormones. She would need to abstain from sex for thirty days, and take another trial medication. She could not say a word to her husband, and then report back to him in a month. Tina was okay with everything the doctor had asked of her. She was to keep a journal once again for the next month. Tina felt a bit of guilt over the next few days. It hurt her not to be able to tell her loving husband Mark of almost twenty years about the new study, because of its secretive nature. She did as told, and kept a journal over the next thirty days. She abstained from sex over that period, even though she was more sexually aroused than any other time in her life. She gave her husband a number of excuses on why she couldn’t make love to him. The thirty day period finally had come to an end. She reported back to Dr. Gundy ready, and extremely willing to be part of his study. Dr. Gundy reminded her again that she would need to do whatever is asked of her, and Tina responded back, “Don’t worry, I will do whatever you ask of me.” “That is great Tina. Are you ready? How aroused are you feeling?” Dr. Gundy replied back. “Very aroused! Those pills you gave me are way more potent than beylikdüzü bayan escort the last ones I took. I am aroused all day long.” Tina said to him. “Ok Tina, here is the place the study will be held at. It is a research location about twenty minutes from here. I want to see you there tomorrow afternoon. Ok?” “I will be there,” Tina replied back. The next day Tina felt abnormally horny. Her pussy was extremely aroused, while moisture dampened her panties. She drove to the research facility all alone, and wondering what the study would consist of. She met Dr. Gundy in the corridor, and was led down a dark hallway to a room. Inside the room stood a bed, along with a wireless monitoring device. His assistant wired several wireless probes onto Tina’s body. This way the doctor would be able to monitor her heart rate, along with a few other vitally important things. The doctor then advised Tina to get fully undressed. He would monitor everything from the room next to hers, leaving her all alone for the next few minutes. She then heard Dr. Gundy come across the audio system. Tina sat patiently on the bed, she was naked and extremely nervous. The lips of her pussy were covered in moisture, while she wondered what the study consists of. Dr. Gundy still didn’t tell Tina what the study had detailed. Dr. Gundy had his own personal study he wanted to try. He wanted to see what happens when you mix two people that dislike or even hate one another into a room for the purposes of sex. He wanted to see if the adrenalin rush and the anger that they each felt for each other can produce significant and powerful orgasms between them. Tina sat there almost stunned. She wondered why the survey wanted to know anyone that she despised. Tina loved almost everyone, though she did list a few people that she didn’t like a whole lot. One was a fellow employee, another was an associate that her husband worked with. She had listed a few others, but her list was just a very few. A few minutes later the door to Tina’s room opened. She sat there extremely nervous escort beylikdüzü and aroused when a familiar face walked in. She never imagined they would have chosen this individual, and now she was stuck in a particular weird situation. It was her daughter’s ex-boyfriend Derrick, who her daughter dated several months earlier. Tina hated Derrick with a passion, and told him to stay away from her eighteen year old daughter after finding out they were dating. Derrick was older, and at twenty two had no real future ahead of him. He had tattoos all across his body and loved to ride motorcycles with his friends. Tina had seen a number of individuals hurt on motorcycles in the past, and certainly didn’t want her only daughter to be one of them. Tina never liked Derrick the first time she met him, and that still held true today. “Derrick! No way!” Tina yelled out while trying to cover up her naked body with her hands. “Tina, remember this is very vital for this study. You agreed to do it,” Dr. Gundy said across the audio system. “I bet you never expected to see me walk in, did you? This is going to be fun fucking you senseless,” Derrick said to Tina. Derrick also had wireless probes on him, and the hope was to follow his reactions just as well. Derrick began to undress in front of Tina. He had removed all of his clothes except for his briefs, while his huge cock pushed outward against them. Derrick was being paid a token amount for his involvement in this study, but he would receive a bonus for every time he could make Tina orgasm. Derrick felt an extreme rush of adrenalin as he walked over toward Tina. Tina’s heart rate began to explode while Derrick got near her. When he got over to the bed he pulled Tina’s arms away from her beautiful tits, exposing each of them. His hands gravitated down toward each of them, while an angry Tina sat on the edge of the bed. “Oh fuck your tits are so nice!” Derrick said to Tina. Derrick took charge almost immediately as he made Tina lie across the bed. “Spread those legs!” he demanded.” Tina lay there with an extremely dirty look on her face, and slowly opened up her legs a few seconds later for the young man. Her pussy was so aroused, and now moisture dribbled down each side of her legs. Derrick now got on top of her, and before Tina knew what had hit her, Derrick pushed his big thick cock deeply into her aroused pussy.
