Nichole sexual experiment.
Nichole was just trying to get her Ph.D. from her, but with the help of an older man, she got so much more.
Nichole was excited to finally develop the physical side of her doctoral thesis. She lay down on the mattress in her study and slowly rubbed her clit. Her academic successes always put her in the mood, and this was her biggest one yet. She had had the idea for her thesis ever since she graduated in Biomedical Engineering and now she finally had the funds to get started. She took the small dildo from her and started working it on her wet pussy. Her funding was less than what she had asked for, but based on her initial results, her advisor was willing to release the full funding and pay for the test subjects. As she imagined taking her experiment to its final steps, she began to tremble and came silently. Nichole lay there panting and fell asleep.
The next day, Nichole had a light day and by noon she was in the machine shop at the School of Engineering. She waited for the technician to wrap himself up with two college students. Nichole stood there in her little 5’2″. She was wearing jeans and sneakers, as they were required in the auto shop. As Criss finished talking to two freshman engineering students, he noticed Nichole standing on the door of the store. He had seen the little cutie before, but didn’t think he had ever interacted with her. He tried not to look or anything, but he was pretty sure this girl had relatively large boobs. It wasn’t noticeable because of her sweatshirt worn, but Criss was pretty sure.
Criss walked over to her and noted that she was older than he had originally thought, “Is there anything I can do for you, ma’am?”
Nichole smiled and held out her hand, “Hello, I’m Nichole, but you can call me Ann. I have an experiment that I need to build for my Ph.D. and they told me I could do it here.”
Criss took her hand and shook it, “I’m Criss. Most PHD candidates just give me the plans and a cost code and I take care of that. You can just email them to the machine shop address.”
Nichole looked down at her toes: “I don’t have the budget to build the project. I have the plans right here, and I was hoping you could show me how to use the equipment.
Criss had been through this before and knew that he was probably telling the truth. The store was pretty busy, so Criss decided it would be best if she came back later, “I’ll tell you what, if you come back at four, I can walk you through the machines and point you in the right direction.” He took the plans from her and sent her on her way.
Nichole was still so excited that she almost ran back to her lab. She would work on the framework of the experiment in the store, but the literal guts of the experiment would be done in her lab. Nichole’s Ph.D. was in obstetric engineering and focused specifically on the addition of lubricants to aid in the birthing process. When she arrived at her lab, she immediately began work on an artificial uterus and vagina. She knew where all the chemicals she needed to make the membranes were, and now she could sign them off with confidence.
The idea was that different types of lubricants can help the birth process and she was going to try pulling a variety of wooden eggs through the cervix and vagina and test whether and how much lubricants reduced the force required. Nichole got to work and by three thirty she had two sets of cured casings.
Criss had reviewed the plans and was initially surprised by what he saw. He then looked up Nichole on the school website and received blowjob porn confirmation that she was actually building a frame to hold a fake pussy and that she was going to get stuff out of it. Criss switched to his phone and searched for his social media accounts. It didn’t take much digging to find it. She kept a pretty clean presence on social media, but he found a photo of her and a friend of hers in her swimsuits that had Criss pumping blood. The sweatshirt might hide her boobs, but this photo doesn’t. Criss reasoned that they might be more than DD, but with her small frame, she looked like he was about to topple over.
Nichole walked into the machine shop and saw Criss at her desk. As she approached him, she quickly put down her phone and began clicking furiously on her computer. Nichole assumed that she had been watching porn, tried to look at her crotch and sure enough, she had a boner. Criss pulled out Nichole’s plan and launched right into it: “Hey Ann, this really isn’t a very big build, and since it looks like you’re putting the important parts together, I think I might as well remove them among other projects. I should have the frames ready in a couple of days.”
Nichole could have kissed him onthe act. She had scheduled three weeks to get the experiments ready, if she worked over the weekend, she might be ready to test on Monday. Smiling, Nichole replied, “Thank you so much, you have no idea how much this means to me.” Criss got up to shake her hand again and Nichole moved closer to hug her, pressing her breast against him on purpose and making sure her hard cock pressed against her stomach. H.
Nichole had never used her body to get something from a teacher before, but she felt this guy had earned something special. She released him and left. She was getting horny again, but she knew she had to keep working on her experiment. She would have plenty of time to get up before bed.
After a couple of days, Nichole went back to the auto shop to check on Criss. She had the frames ready to go. They were two two-foot cubes made of strut, with a vertically suspended ring slightly off center. Nichole inspected it and was glad it was perfect. However, she still didn’t have enough room in her lab for these. “Hi Criss, these look great! Mounting rings and everything, can’t wait to hook it all up.”
Criss was glad to see the girl again. She wasn’t really a girl, at 24, but compared to his 45, she looked young. He smiled at her trying to get it out of her head how much she wanted to fuck this petite brunette. “Yes, everything should be there. Where is your lab? I can take them where you need them.
Nichole frowned slightly, and Criss knew she was going to ask him for another favor. However, he would, whatever she wanted, she probably would at this point. Nichole finally chimed in, “My lab is really cluttered right now with the casts and stuff for the uterus, is there a free desk down here where I can put them?”
This wasn’t too big of a question. The machine shop was in the basement of the building and Criss had a couple of storage rooms assigned to him. He thought for a second which one would be better. “I think I can figure something out. I have a workbench in room B11 that I could mount them on, that way you could still use your lab to make the other pieces.”
Nichole smiled at him again, checking that the room was empty, and gave him another sensual hug. Criss closed her arms around her this time and she felt her cock grow hard. She had never understood how a woman could use her body to get things and not feel bad afterwards, but this felt different. At least she justified it that way. They eventually released him and Nichole thanked him as she left. When she got to the door, she remembered something: “Oh, here, let me write down my number. Once the frames are ready, I’d love to try them out.”
Criss took her number and waved her out. When he was pretty sure she was at the end of the hall, he closed the machine shop door and went to her desk. He had the photo of Nichole’s swimsuit saved on her phone and within seconds he was rock hard and beating that cute young thing.
The next day was Friday and Nichole had no classes. She had finished the first two simulated wombs and had thrown them away when the next pair was complete. She already had the third set healed but these two should be perfect. She looked at the modeled vaginas, the front lips themselves taken from a mold Nichole made of her own sex. The molds didn’t really capture how cute she thought her pussy was and honestly no one would believe that these silicone messes were modeled after a real pussy.
She jumped when her phone rang. It was Criss, “Securing the frames now, it should be ready to use in twenty.”
Within ten minutes, Nichole was knocking on the door of B11. Criss let Nichole in and, without a word, went to work on the frame that had already been secured. Criss went to work on the other frame. Every time Nichole had come downstairs, she had planned to wear clothing that covered her, since today she came from the lab upstairs, she coincidentally wore a tight t-shirt that showed off her beautiful breasts. Criss did his best to focus on his task, finishing just before Nichole was ready to mount her second womb. He stepped back and let her get to work.
When she finished, he took a step back and noticed that Criss had been watching her. She gave him a big smile and pulled her laptop out of it. She threaded a string through each of the vaginas and uteruses and connected them to strain gauges on one side and 4-inch-diameter wooden eggs on the other. Nichole connected the other end of the tensiometers to a small motor. After setting up her meters and her laptop, Criss could see two graphs on her screen. Nichole fired up both engines and they began to zHe lowered himself and Criss could see the data reflected on the screens.
The eggs were taken to the fake cervixes and after a couple of minutes the motors burned out. Nichole was devastated. She was on the verge of tears when Criss finally said something, “It’s no big deal, I probably should have told you it was a bad idea anyway, you’d be better off using a counterweight than those little motors. Give me a second.”
He was back in an instant, handing Nichole a set of brass weights while she fiddled with a basket that hung from the side of her desk. Within minutes, Nichole was collecting data again. She added weight little by little until the eggs came out. The blood pressure monitor showed a clean graph and Nichole was in a trance. They went on like this for another couple of hours until the artificial cervix fully opened.
Criss was exhausted but Nichole was ecstatic. She wanted to run home and process the data that she had collected. She turned to Criss to thank him and saw how selfish she was. He had been helpful throughout the process and Nichole thought she owed him a lot. She walked over to the chair he was in. Before Criss realized what he was making of her, she was so close to her that she couldn’t stand up without pushing her away. He was about to speak when she fell to her knees.
She kept eye contact as she unbuckled his seatbelt and flew off. She reached out and pulled her jeans down. Criss shivered as she wrapped a hand around her cock. She wasn’t huge or anything, but she felt like a god seeing her small hands wrapped around his shaft and her big green eyes staring up at him. He was so fixated on her eyes that he didn’t see her stick her tongue out at her. The feel of her warm, wet lick moving up the length of her made him gasp.
Nichole hadn’t had too many relationships in college, but because of her painfully tight pussy, she had perfected cock sucking. Criss clearly hadn’t seen this coming and her cock was musky and sloppy, but he had helped her so much that she didn’t let any of it get to her. He placed the head of her cock in her mouth and began to work it down her throat. He didn’t understand why she could take a cock in her mouth with no problem, but her vagina was too tight. As she began to swallow deeply, her mind wondered how he could use her experiments to help her relax a bit. Before he knew it, Criss yelled, “Can I cum on your tits?”
Nichole tore her mouth from his cock and removed her top and bra. Criss wasn’t the first guy to ask this, and though Nichole was embarrassed by both the size and sagging of her boobs, the guys didn’t seem to care. She began to slide the head of Criss’s cock in and out of her mouth until she felt him freeze. She aimed his cock at her neck and her tits and kept stroking her. Criss grabbed the chair as he came over the girl.
When he finished, Nichole stood up and wiped his cum from her tits and deposited it in her mouth. She swallowed it all and put her shirt and bra back on. She smiled at Criss, “I’ll take this data and start analyzing it, but I’ll let you know when I do my next round of testing.” She grabbed her bag and left.
Criss was in a daze all weekend, when he arrived on Monday he was surprised to get a text from Nichole, “Hello, B11 at 4.” Criss felt his cock tighten. The day passed slowly, but at four he went to the storage room and opened it. He had barely entered when Nichole called out to him, “Hey, can I give you a hand?” She was down the aisle pushing a cart with various silicone models on it. Criss moved to help her and soon Nichole was hard at work preparing the new wombs. Monday looked a lot like Friday, even ending the same way. Criss was ecstatic when Nichole said “See you tomorrow.”
Nichole went back to her apartment and began to collect the data. After an hour, she knew that she needed to come. She had planned Indian Brother and Step Sister Sex her experiment a long time ago and already had the next phase ready. If the silicone and wooden eggs provided valuable data, then she was going to move on to the real thing, inserting small, rigid balloons into women’s cervixes, inflating them, and then pulling them out. She already had the balloons purchased with the money she saved in the trial frame. It could be inflated to four inches in diameter, but Nichole only planned to get to an inch and a half for her experiments, without needing to rip open people’s cervixes.
Nichole inserted one of them into her wet pussy and using a bicycle pump pumped it up as much as she could without pain. She shivered a bit, but when she leaned back into her vibrator and continued to work, her pussy relaxed and she was soon enjoying the feeling of fullness. she kept workinggoing until he was close to climax. Barely able to control herself, Nichole reached down and inflated the balloon a little more. She hurt me but she was until she came. As she climbed down, she slowly pulled the balloon out of the shell in embarrassment that it had barely reached an inch and a half in diameter. A little dazed, Nichole forced the balloon back into her and fell asleep.
The rest of the week she flew by. Nichole continued to work with Criss in the evenings and made sure he got paid from her, during the day she worked on her data, preparing it to send to her advisor. By the end of Thursday, they had completed all of Nichole’s planned tests. As she whistled at Criss, she came up with an idea that might influence her adviser to give her more funds right away.
After swallowing Criss’s load, Nichole hurried home to make sure everything was ready. As she gathered what would be needed for her latest experiment, she began to get excited. She still had the balloon in her pussy and it was two and a half inches. Nichole knew this wasn’t much, but it wasn’t painful anymore and she knew she could take a cock. She let some air out of the balloon and began pumping it in and out of her pussy. She went over the next day’s activities as she applied her vibrator to her clit.
Four o’clock couldn’t come soon enough for Nichole. She had a bag filled with everything she would need Criss to wear. When the two were finally alone in the storage room, Nichole explained what she was planning: “I want to try something different tonight, I want to try the real experiment on myself.”
It took a second for Criss to understand what she meant. Before he could respond, Nichole had already started undressing. Criss’s mouth was open wide as he looked down at Nichole’s body. From her stomach down she looked intact and nubile, her pussy completely bald with no visible lips. It seemed so tempting. From her boobs to her top, even though she was completely female, she got a good look at her large areolas and her tiny nipples. She had a determined look on her face that showed her age. She cleared her throat, “I’m going to need you to open me up a bit with the speculum and then apply this ointment to my cervix. After an hour it should be ready for testing. You will insert the balloons, inflate them until you hear a click, take them out and we will record the data.”
Criss agreed to help and Nichole climbed onto the workbench between her two frames. She used the frames as stirrups and exposed her sex to Criss. Criss applied a little lubricant to the speculum. He got close to the cutest pussy he had ever seen. He parted her lips and regretted that this was how he interacted with her. He pushed the speculum inward, eliciting a cry from Nichole as the cold steel touched her delicate garments. He soon had her open and with the help of a flashlight he was able to see her cervix.
Criss had fucked a lot of women in his life, but he had never really seen the little lightbulb with the hole in it. The ointment smelled like a cleaning agent, but Criss dipped a finger in it, then smeared it around Nichole’s cervix. “Is that good? It looks like it’s covered.”
Nichole was feeling a soothing tingling sensation in an area of her vagina that she didn’t know she could feel. She looked at him between her legs, “Yeah that should be good, now let’s just wait an hour.”
Criss pulled the speculum out of her and her pussy relaxed back to her lovely state. An hour was a long time and Criss was pretty tough. He had never asked a woman this before, but he knew this was no ordinary situation: “Can I jerk off while we wait? I’m having trouble concentrating while looking at your pussy.”
Nichole was surprised that she blushed. She realized that she could have explained things a little better and felt bad because he felt that he would have to punish himself: “You can if you want, but give my pussy a minute or two to relax and I can go down and suck.” . your dick instead. Nichole wasn’t sure if she’d said pussy or dick to a guy she was sexually intimate with.
Criss nodded and simply stood until Nichole started to dismount from the table. Criss moved forward and simply picked her up and set her down on the ground. Nichole had realized that he was older than her, like most boys, but she hadn’t realized how strong Criss was. She quietly undressed him and, to her surprise, he had quite large arms and, although he didn’t have a ripped abs, he still had a toned stomach. Nichole looked at him, “If you lie on the floor, we could sixty-nine.”
Criss was on the ground in an instant. Nichole turned around and straddled his chest. With her head on his cock, her pussy was too far away for him to reach, though she had incredible eyesight.As she lowered her head, she felt his rough hands grab her saggy tits. She felt Criss’s strength again as he squeezed her breasts just as hard. If she didn’t have a cock in her mouth, she would have screamed despite his arousal. Her hands were callused and bruised from working all day in the auto shop, and Nichole felt dozens of pricks in her soft melons. As Nichole drove Criss’s cock down her throat, Criss picked up her pace and was soon squeezing her and pulling on her tits at the same time.
Nichole nearly cried from her sexual frustration. If she had any stimulation on her clit, she would come. Criss pulled hard and Nichole slumped a little, spreading her legs farther apart and landing her wet cunt on her chest. Nichole lit up when she felt something to rub against. Criss marveled when the little kitten pressed against her chest, inches from her face. Between his beautiful pussy, soft mouth and juicy tits, Criss was on top of her and soon he came down Nichole’s throat. As Nichole swallowed, he rubbed harder until she came too. They lay on the ground for a minute before Nichole got up and started setting up the tension meter and balloons.
Her phone’s alarm went off and Nichole went back to the table and spread her legs. Criss didn’t need lubricant for her speculum since she was still soaking wet. Criss could have sworn Nichole’s cervix was bigger than it was an hour ago, and he was a little less worried about forcing something there. Nichole guided him through the process and soon he felt the tip of her globe pressing against her. Small hole. She winced when Criss forced the device into her womb and she was relieved when she finally stopped thrusting.
The pumping sensation was completely different from when she had done it in her vagina. She was about to scream when she heard the click, which meant the balloon was an inch and a half in diameter. Criss stopped pumping and turned on the strain gauge. With a nod from Nichole, he began to apply charge. It took almost twice as much weight to get the balloon out of her, and since it was a non-lubricated attempt, Nichole felt a lot more pain than she expected.
However, they got clean data and Nichole mentally prepared herself for the next round. She had planned for the proof of concept to consist of two control pulls, then four lubricated pulls, but when the balloon went through her a third time, she was about to win. It was the first lubed round and that helped a lot, but even Criss noticed that her cervix remained more and more open with each round. After the fourth pull of six planned, Nichole gave up. She handed Criss her phone and asked for some photos before he removed the speculum from her. Nichole almost cried when she saw how beat up her hole looked.
Criss picked her up from the table and they began to clean up. Criss reached for her boxers, but Nichole stopped him. She guided him back to the floor until she was lying on her back. Nichole grabbed one of the lube bottles and dabbed a couple of drops on Criss’s cock. She mounted him and began to rub her shaft against her lips. Criss loved the feeling and he was hard almost instantly. He reached up and began massaging her large sagging breast.
Criss was a little nicer this time since he was worried about what had just happened. That’s why he was surprised when she got up and guided Criss’s erection into her soaking wet cunt. She lowered herself, inch by inch, and Criss reveled in the feel of her pussy. She was tight but so wet that he slid inside her. She realized that if she hadn’t come that night she would have already lost him. Somehow he still looked so young and innocent as she bounced up and down on his cock.
After some thought and a lot of excitement, Criss decided she was ready for a little roughness. He adjusted her grip on her tits so that her thumbs wrapped under them and the rest of her fingers were visible to both of them. He then pushed both breasts together and squeezed hard. Nichole let out a moan as she watched the flesh of her slip out between Criss’s fingers.
She pulled them toward her face, forcing Nichole to lean forward. This had the added benefit of putting much of her weight on her pelvis and clitoris. She concentrated on the pleasant touch as Criss began to suck on her tiny nipples. Nipple play had never done much for her, but she loved how rough he was being in general. However, there was one minor problem: in this new position, Nichole could feel his cock brushing against her cervix with each thrust. It was a new experience and it was not entirely unpleasant for her. As she concentrated on the slight burning sensation and the incredible sensation of her clit rubbing against Criss, she began to cum.. He let out a couple of screams and ran out of steam.
Criss stopped squeezing her boobs and grabbed her. She just smiled and looked at him, but she didn’t move. Criss was eager to cum and he saw this as his best chance to really fuck this girl. He turned around so that Nichole was now flat on the ground. He held her legs and almost laughed at how limp and flat her breasts now looked, still huge but deflated. He pulled her cock almost all the way out of her and shoved it back in. Nichole let out a moan as Criss began to pound into her small body.
Nichole had been sexually active since high school, but this was the first time he really felt like she was being fucked. Penetrative sex was too painful until the last week, and now she was enjoying the feeling of this man putting everything he had into her. Criss only lasted a couple of minutes before he pulled out of her and sprayed her cum all over her tits again. Nichole smiled as she brought her tits to her mouth and licked them clean.
Criss dismounted and they both got dressed. Nichole was in the doorway when she turned to Criss, “Well I think this wraps up my proof of concept, if I get approval from my advisor I will run this same experiment on multiple subjects. I’ll probably need a hand with all of that.
Criss couldn’t believe his luck, “Whatever you need, I’m sure I can help you out.” She smiled again and left.
