Just a heads up, this sucker is long, but I'll be around all day.

"Hey, Hannah, I know you've got a lot on your plate this semester, but I have a research project that I think you might be perfect for. If you can stay after class for a bit, I would love to tell you all about it."

That was how it all started.

So, I'm a first year college student majoring in Human Sexuality and Sexuality Studies (yes, it's a real major, pervs, go look it up). As unorthodox as it is, it's actually a really interesting field to study, for more reasons than you would expect. The history and the nuances behind human sexuality and its development is crazy intricate, and it's absolutely fascinating to me. But the reason I love my classes so much is my professor.

Again, perverts, get your mind out of the gutter. He's not some young, super cut hunk of a college professor that you see in movies. And it's not some busty MILF who has offered to coach me through my lesbian college phase. He's actually not very attractive. He's older, probably at least 50, glasses, a little hairy, a little out of shape to be perfectly honest. Definitely not my type, so don't even think about it.

But he's an absolute genius. Just listening to him lecture about any topic related to sex is fascinating, the amount he knows is just mindblowing. I could listen to him talk for hours, it's to the point that his class isn't even a chore like my other ones. Nobody else seems to feel the same way, either, which is weird. I guess that's why I quickly became the top student in his class.

And I'm guessing that's why he chose me, of all people, to be his research assistant.

You see, even though being a professor makes his living, teaching classes is only the half of it. Research is what the university really pays for, and he always has a new theory in the works. He told me that he usually gets his first year students to help him, to ease the workload so that he can focus more on his lessons. And, he said, this particular study he needed my help for was his biggest passion project, and his most promising theory to date.

My professor is studying the link between arousal, pleasure, and fertility. He said that he'll be studying the link in the female body next, but right now he's currently focusing exclusively on male fertility and, as such, male arousal. Does a man's level of arousal raise his sperm count? Does the strength or volume of his orgasm impact his fertility? What are the effects of frequency of sex on fertility, does it change when ejaculating twice a day, four times a day, ten times a day? In essence, how is a man's fertility effected by overwhelming, and near constant, sexual pleasure? He said he's been studying this topic for years, with a number of assistsnts, and he thinks with my help he'll finally be able to come to a proper, evidenced conclusion.

Like I said. He's truly a genius.

So, for the past four months, I've been assisting him with his research on an almost daily basis. It started out with simple things, like differing levels of foreplay and different sexual positions. We spent the better part of three weeks just on this alone studying the different variables. What's the ideal length of time to suck a man's cock before sex? Does cleaning off his cock after sex have an effect? Which position increases arousal more (doggystyle, cowgirl, missionary, etc)? It was taxing, the amount of man hours we were putting in, but my professor said that I was the most dedicated assistant he'd ever had. It started to take a toll on my performance in my other classes, but he told me that with the work I was doing here I might be able to bypass most of my basic credits once our findings were published.

From there, things got more advanced, more intricate. We had to study the effects of frequent procreation or, to use layman's terms, 'marathon sex'. He dismissed me from my classes, and canceled his own, and we essentially lived out of his office for an entire week. The entire process was exhausting, but it gave us ample time to examine other variables as well. Things like dirty talk, shower-sex, rimming, swallowing, and plenty more. We spent an entire day performing research with the effects of edging, which was one of our greatest successes. We discovered that edging had even better results on fertility if it's followed by a period of the male partner cumming as much as possible. It's been a rewarding term, even if it did an absolute number on my grades in my other classes.

I've learned so much about sex, and human sexuality, from him that I never could have learned on my own. For example, he taught me that the first load of the day is typically less fertile, and is more suitable for being emptied onto my face rather than my pussy. He showed me how effective being referred to as 'sir' or 'Daddy' can be for older men, and I now refer to him exclusively as such during our sessions. He's taught me different techniques for administrating oral sex, the value of a standing 69 position, how pleasure can be enhanced by sharing him with my roommate, positions designed to keep my pussy as tight as possible to enhance male pleasure, you name it. It's been an exhilarating and rewarding experience.

It hasn't been without its costs. My Professor takes our research seriously, and protecting the scientific integrity of the work we do takes top priority. As a result, there are a few stipulations to our participation in hands on research. For one, obviously, our work has to remain as secret as possible. If anyone was to know that my professor spends hours at a time, day after day, using my body to make himself cum as much as possible, it would certainly draw unwanted attention. Competitors might catch on to what we're doing and try to steal our research! I had to get his consent to even post this, with changed names of course. And, while our research is being undertaken, I'm forbidden from having sex with my boyfriend. My Professor informed me of the little known discovery that another man can potentially contaminate our data if I've had sex with him within a certain period of time. My ignorance to this fact, of course, led to our first week of research being rendered invalid, a mistake I had to work overtime to mend. And then we have to discuss the recording of our research sessions.

Of course, all of our research has to be documented, so everything we do is filmed, typically from multiple angles. We'll usually sit down and review the footage after every research session, or we'll begin the next day's session by reviewing yesterday's footage while I warm him up. He takes notes, makes critiques, points out ways that I can be more effective as an assistant. My professor, always the professional, has been transparent with me about the fact that it's this video documentation that allows him to secure continued funding. He has a few research partners who have invested in the project that he sends the footage to, so that they can catalogue everything, in exchange for more money to continue with his research.

And now that we're nearing the end of the semester, I had started to assume that our work would be winding down. He told me that typically he works with an assistant on a project for only a single semester, and then he moves on to a new project with a new assistant to keep the experiments controlled. But just last week my professor had another incredible breakthrough. He said that now that we've established a strong control group, it was time to test the variable of women themselves. So, my latest job has been to recruit other assistants to take part in the research with us. We spent hours looking through my friends on Instagram and TikTok, taking notes on which girls would be perfect test subjects, which would cover the largest variety. And, of course, now we get to test the effects of multiple partners at once. The difference made by one man being shared by two women, three women, five women.

With this new theory in mind, my professor has said that we might have to continue our research into next semester.

This wasn't exactly how I figured I would be spending my freshman year. I figured there would be more dorm room parties, boozing, sneaking into bars, girls nights. But I have to admit, I think it's all worth it. Partying would have been great, but I'm here at college to get an education. And that's exactly what I'm doing.

As for playing this out, I know that I wrote out most of the plot here, but that was largely just to get a feel for the direction I was hoping things would go. I would love to go back towards the beginning of the story, the beginning of our 'research' so to say, and work our way forward from there. It can be an abridged version if you're more excited to get into the endgame, but I would like to play out at least some of the developments between our two characters as you mold me into a perfect lab assistant.

As far as my own kinks go, I'm really into manipulation, playing naïve characters, sloppy blowjobs/oral in general, FFM scenes, cumplay, huge cocks, vocal men, older men, hairy men, age gaps and sizeplay, one-hot/one-not, rough sex (spanking, hair pulling, dirty talk, tit slapping), titfucking, rimming (giving), but I will say that as much as I love rough sex, I don't particularly care for BDSM. Limits include bathroom play, noncon, gore, vore, abuse, futa, bestiality, bondage, people who brag about writing 1-2 paragraphs, people who send me slightly adjusted form letters as a response.

Send me a message (DM, no reddit chat, sorry) if you think my idea is fun, or if you like to write, if you have feedback on my prompt, or if you think I'm weird. Please don't send me a message if you want to chat on kik, hook up IRL, or talk about something entirely unrelated to my prompt. It just doesn't interest me, I'm sorry. Unless it's specifically related to my prompt, I tend to pass. Just being honest, I don't want to waste anyone's time
