Biology 101

By: Phallicwhale



Ami Markham hurried across the quad, a satisfied smile on her lips. She'd just gotten her latest term paper back in Japanese history, and she'd gotten another A+. Her Professor had disagreed with Ami's conclusions about the end of the war with America, but she had admired the logic of Ami's argument. One of the nicest things about Dr. Tanaka was her willingness to recognize a student's right to disagree, at least as long as they could logically defend their opinion. 

Now Ami was heading for her favorite class of the day, Biology 101. Prof. Yamato was a handsome young professor, with an informal style that still managed to convey a lot of information. Plus, Ami wanted to follow her mother into the medical profession, so Biology was essential to her ambitions.

As usual, Ami was one of the first students to arrive at the lecture hall, and she took a seat near the front of the room. Most of her other University instructors insisted on assigning designated seats for their freshman classes, but Prof. Yamato let everyone sit where they were most comfortable. In another class this would have been inviting disaster, but he had the ability to command even the most insolent student's respect and attention.

As she entered the room, Ami noticed a sickeningly sweet smell in the room. Looking around she was unable to discern the source of the odor, but it was becoming slight nauseating. As the rest of the students settled into their seats, complaining about the horrible smell, Prof. Yamato entered from his office.

"What is that smell? Did someone set off a stink bomb in here?" he complained. "Miss Markham would you help me open the windows please, and Miss Webster get the air freshener from that cabinet." As soon as they opened the windows a cold breeze filled the room. That morning had been the coldest of the season, and it didn't appear the afternoon was going to be much better. By the time the last window was open, it was obvious that they couldn't remain so for very long. Liana Webster had begun spraying the room with a lemon scented air freshener, but that only seemed to make things worse.

Realizing he was going to have to close the windows soon anyway, Prof. Yamato motioned for one of the boys to begin closing them. "I guess we're just going to have to live with the smell folks. Although," he paused. "I was given some new incense that might do the trick. It certainly can't make things any worse." Going back into his office, Prof. Yamato was heard rustling around in his desk. "Ah, here it is."

Returning to the lab, he placed a small plate on the corner of his desk. "Well, nothing to do, but give it a try."

"What is it called Sensei?" Liana asked.

"Um, let me see." he tipped the box to read the label. "'Essence of Aphrodite.' Well that should certainly be interesting." With that he pulled two of the thin reeds from the box and lit them. A delicate cinnamon scent began to fill the air, it was so light, Ami was amazed at how quickly it began to clear the air.

"Alright class, as you know we are about to start a new subject today. I know the next chapter in you text book is about amphibians and the dissection of a frog, but I thought it might be more interesting to skip a few chapters. Moreover, the school forgot to order the supplies in time." A general laugh filtered through the room. "This next subject is one I'm sure you remember from High School, but it's time for a more in depth treatment." A murmur of surprise and conspiratorial glee ran around the room. The University Chancellor was notoriously rigid about professors keeping to their syllabus's schedules. Prof. Yamato was constantly getting in trouble for his little revisions, but his students loved him for it. The fact that he was tenured and that his students were consistently among the best performing groups on the MSATs kept him from getting into too much trouble though.

Striding over to a display easel covered by a black cloth, Prof. Yamato pulled the cloth away with a flourish. "Our next topic is 'The Reproductive System of the Human Species.' The silence and sense of disappointment in the room was palpable. Then slowly a nervous excitement came over the students. One thing was certain; Prof. Yamato would be a lot more relaxed and enlightening then their various High School teachers had been.

As the professor began pulling his displays out to the front of the class, Ami noticed that the incense had completely displaced the rank smell from earlier. A small voice in the back of her mind also tried to point out the strangely sensual feelings stealing over her body.

At first the lecture was pretty much the cut and dried presentation they remembered from H.S., but as he continued Prof. Yamato began to become more and more expansive and uninhibited in his behavior. "Alright class, now we get to the good stuff, the manner in which the male deposits his semen in the female's body." 

"This is supposed to represent the 'penis'," he held up a small representation of a flaccid cock. "Doesn't look like much, does it ladies?" A small snickering sound filled the air. "Well when the male is sexually aroused, it can grow up to three times its normal length. Here I'll show you." With that Prof. Yamato proceeded to undo his belt and dropped his pants to the ground. The shaft thus exposed was easily four or five times the length of his model and much thicker too. "See! That's what I'm talking about. Now, once his penis has reached its full length, the male takes it and inserts it into the female's vagina."

Stepping completely out of his pants, Prof. Yamato reached over and picked up his next exhibit. "Hmmmm, you know this really doesn't give you a good idea either. I need a volunteer from the distaff side of the class." No one seemed surprised when the entire female half of the class raised their hands. "Ok, let's see.....Miss Markham, (oh the hell with it) Ami! Come over here and help me out."

Ami didn't even hesitate before she stood up and went to where the professor was indicating. Deep in the back of her head a small voice was crying "Stop!", but her customary reserve, and self-restraint were nowhere to be found.

"Ami, would you please sit on the table and remove your panties. Class, the rest of the girls might want to do this too. That way you can get a better idea of what I'm talking about." Immediately the entire class, including the boys, began to disrobe from the waist down, shifting so that every one was paired off with a student of the opposite sex. Only a few of the girls at the back of the room and farthest from the incense seemed to hesitate at all. 

Reaching over, the professor lifted Ami's skirt and directed the class' attention to the front. "Now class, this is what a vagina looks like. Normally a girl as well developed as Ami would have pubic hair covering the area. Miss Markham has apparently made the decision to shave most of hers off. Am I right Ami?"

"Actually Sensei., I just had it waxed. I spend a lot of time in bathing suits and leotards, so it's more comfortable this way."

"Well, lucky for us that you do. It makes it a lot easier for me to show everyone what I'm talking about. Ladies, if you are done examining the men's cocks, please allow them a closer look at your . Now the vaginal opening is composed of several items." Reaching down he ran his finger along Ami's moist pussy. "This outer area is called the vulva, and it consists of the outer and inner Labia. Most of the time this is tucked up inside of the woman, but as you can see, when she is aroused they tend to swell slightly and become covered in a lubricating discharge."

The sensations from Prof. Yamato's touch were sending little bolts of pleasure through Ami's body. "If you take your fingers and spread these folds apart, you will find two items of interest. The first and most obvious is the vaginal opening. If you want, take you finger and slide it into your partner's orifice. You'll notice that in many cases, the walls of the vagina are so tight you can barely insert the finger more than half way. Don't worry guys, if you just continue moving your finger in and out of this opening, it will relax and allow you easier access." This statement was followed by several gasps of pleasure coming from the female class members.

"Up at the top of these folds you will notice a small object possibly standing erect. This is called the Clitoris, or Clit for short, and it is very sensitive. Most women love to have this tiny jewel gently caressed, it helps them get fully aroused and bring on their orgasms. Here watch as I demonstrate." Ami trembled as the waves of pleasure coursed through her body. Her throat began to emit small moans of delight as he expertly manipulated her tiny Jewel.

Now in between these two points many of you may have noticed a tiny opening. This is the urethra and unlike in the male penis, has little if anything to do with the reproductive cycle, although some women have admitted to deriving pleasure from having this opening stimulated.

"Some of you may have noticed an increase in the amount of fluids flowing from your partners vagina. Don't be alarmed this merely indicates she's getting ready to accept your penis into her body. Now, there are many ways of accomplishing this act. I won't bore your with a complete listing of the various positions. My personal favorite is to enter the vagina from the rear. This allows for the maximum penetration of the penis. Ami would you mind leaning against the wall? That's it. Now, spread your legs just a little."

The professor reached down and lifted Ami's skirt so everyone could see. "Now, you won't be able to insert your penis all the way in at first. It takes some patience, and a degree of skill. I'll demonstrate. The sensation of Prof. Yamato's cock entering her pussy was sheer bliss for Ami. 

"If the girl is a Virgin, you will encounter some resistance just inside her channel. Don't worry girls; it only hurts for a moment." Under his breath he said, "I see you've done this before. I never would have guessed."

Behind her, Ami heard the sharp gasps as the last of the Virgins in the class lost their flowers, but by this time she was too enraptured to care. Prof. Yamato quickly settled into a slow rhythmic motion, as he thrust his cock deeply into her throbbing cunt. Each thrust sent waves of delight washing out over her body and her breathing soon become ragged and heavy. It felt like she could detect every bump and ripple along the entire length of his cock. 

With his hands Yamato reached around and began to fondle her chest through the fabric of her blouse. Even with the cotton material of her shirt in the way, his hands brought small thrills of pleasure to the lust filled vixen. The smooth delivery of his earlier lecture had disappeared as he said, "Boys, (huff) you might try fondling your partner's breasts as you (deep breath) do this. Most women seem to enjoy the (uh) sensation, and I think you'll enjoy it too." 

"In fact," he said, "you will probably want to get their clothing out of the way as much as possible." With deft hands he quickly undid Ami's blouse and pushing her bra up over her breasts began pinching and kneading them with expert care.

Within moments Ami was coursing on the edge of orgasm, and only her intense desire to only come when Prof. Yamato did kept her from screaming her pleasure right then.

"By now a few of you boys have probably noticed a tingling at the tip and base of your cocks. (ungh!) This is a sign of your impending orgasm. With practice you will be able to hold off this reflex, so you can increase your lover's pleasure. Don't be concerned if you can't control yourself yet. At your age you should be able to maintain your erections even after coming, at least until you partner reaches her climax."

The professor had started increasing the pace of his thrusts, and Ami was losing the battle to delay her own climax. Yamato stopped giving instructions to the class as he fought off his own climax. Behind them, the sounds of multiple orgasms filled the air. Several of the girls and two of the boys had achieved more than one climax. Now as the frenzy of sexual activity slowed, Ami's classmates turned to watch as Prof. Yamato continued to take her from behind. All other sound faded as their animal moans filled the air.

Both of them were determined to delay their own climax as long as possible, in hope of reaching it together. Finally Ami could hold back no longer. She screamed in exultation as her vaginal muscles clamped down on her Sensei's rod, and cum gushed from Ami's exhausted body. Feeling her climax, Prof. Yamato sprayed his own copious release into her overflowing vessel. It took several moments for his cock to stop spurting his seed into her pussy, and each throb of his cock sent small shivers of delight up her insides. When his cock stopped pouring its load into her pussy, Ami's muscles relaxed enough to let him pull his shaft out.

Turning to face her Sensei, Ami dropped to her knees and quickly took his penis into her mouth, using her tongue and lips to quickly cleanse the fluids coating its now semi flaccid length. All thought of the lecture, or the fact that the other students might be watching had flown from her mind. All that mattered was doing whatever it took to get his wonderful instrument ready once more.

Ami had now taken control of their dance and with gentle pressure pushed Yamato back against the middle of the three lab tables at the front of the lecture hall. Not letting his cock out of her mouth for even one second she managed to get him up onto the table and far enough back that only his calves and feet weren't on the table. Stopping only long enough to yank her bra all the way off, breaking the shoulder straps as she did so, she climbed out of her skirt and on the table to sit straddling Yamato's midriff.

There was nothing of tenderness or love in the kiss she gave her professor then, only raw carnal desire. Any remaining hesitancy on the part of his organ fled and he became rock hard once more. Reaching down she eagerly guided its head to her opening and dropped her hips even as he thrust up to meet her.

The resultant jolt of pleasure as her body reacted to once more being impaled by Yamato's organ was almost enough to send Ami into an immediate state of rapture. Arms straight, hands on her professor's shoulders, eyes locked with his, she began to slowly draw her hips up and down the fiery shaft of pure delight within her. Each successive thrust brought its own mini climax, and sensual moans of delight came from her throat. 

Those of the class unable to continue their own activities found their eyes drawn irresistibly to the sight of Ami riding Yamato's cock clothed only in her open white blouse. The sight of her there, perfectly formed breasts half seen though the now translucent material, combined with their own post coital euphoria seemed to make it as if they were each apart of the spectacle before them.

Slowly Ami began to increase the speed and force of her downward plunges, as small balls of lightning seemed to coruscate across her eyeballs. Suddenly she shifted position so her hands were now behind her on Yamato's thighs, her blouse falling away so only her arms were momentarily obscured by its material, before it fell from her shoulders onto his thighs.

With every bit of their copulation now visible to the enraptured class, she alternately lifted herself almost completely off his wand, and then ground herself against his pubic bone. Within moments the pleasure became too much for both of them and they came with shattering orgasms so forceful their mixed juices actually fountained up onto Yamato's chest, belly and the table beneath them. 

Somehow Ami maintained just enough control to keep her torso from collapsing backward and falling off the table, instead managing to pull herself to the side and laying beside her exhausted professor. 

Luckily for all concerned, this was the last class to use this lecture hall that day. Slowly, the students began to gather their clothes, books, laptops and sundry other items together and either singly or in small groups exited the room. Ami was neither the first nor the last to pull herself together enough make her departure, but she was one of the few who had to leave without being fully clothed. Her panties had completely disappeared and her brassiere was now useless with its broken straps.

Wrapped in a post-coital afterglow the normally shy and studious girl danced across the quad to her next class. Despite the fact that each spin and leap revealed her naked pussy, and her half buttoned blouse alternately was either clinging to every curve of her supple breasts or flying open enough to display them to all in eyeshot. 

For the first time in her life, she decided to skip her next lecture and instead moved to one of the quieter corners of the campus. The southwest corner of the quad gave way to a small valley where "Mirror Lake" a small pond was located. Although it was surrounded by a walkways, there were still several areas where one could find relative privacy in its environs and Ami quickly found one of these. Her back against one of the trees, she leaned back closed her eyes and (one hand gently stroking her naked flower) fell into a light blissful doze.

It would be several days before anyone would stop to wonder what could have caused a simple biology lecture to turn into a full on orgy. The cause of the foul odor that had permeated the hall was never discovered, nor was anyone able to find the box of incense Prof. Yamato had used to clear the air. Only those directly involved ever made the connection to that day and the sudden flurry of births at the University Hospital the following year.

To be continued?

Biology 101 Pt. 01



My name is Professor Emily Burke my students call me Professor most the time and sometimes Miss Burke. When I'm not around they call me many different things relating to my looks and large breasts. I teach biology 101, which means I have hundreds of students a semester, exactly how I want it. Most are young, just out of high school, the perfect specimens for my fetish.

I have a huge thing for watching young, strong men ejaculate. You might not think that very strange but it goes deeper than that. Not only do I like to watch, but I also have a need to collect the results. That's where my students come in. Sure I could rent videos, surf the web for hundreds of ejaculation videos but none of that comes with the actual sample of semen. To me, being able to touch, smell, taste and keep the results of what I see is the ultimate turn on.

When I began my exploits, I thought it would be harder than it was to secure what I needed. However, I found out rather quickly that young men, especially those not doing very well in my class, were more than eager to do what it took to receive an A. I found my 'volunteers' usually after the first test. They were the ones that flunked miserably and fit the physical requirements.

This year was turning out to have a very good selection. I had my eye on five young men after the first test. All five received a D or lower and all were strong, good looking, first year freshmen. I put a note with each of their tests that I wanted to see them and for them to set up an appointment with my TA (Teachers Assistant). This year my TA was a graduate student named Tami, a bubbly blond with breasts almost as large as mine. She made it easier for the boys to make an appointment because they liked to stare at her rack.

"I made all the appointments Professor; every one of the guys showed up like you said they would."

"Excellent, that will be all for now Tami," I said taking the list from her.

She smiled, turned and left my office. I looked down at the list for the first appointment. It wasn't for another half hour with Steve Coburn, so I had some time to kill. Inside me office I have my computer monitor on my desk so I can watch some of my past students receive A's by recording themselves masturbating. I use media editing software to combine the best videos into a collection. I watched some of my favorites while I waited for Steve to arrive.

Right on time a knock sounded on my door. I turned the clip off, removed my hand from between my legs and told Steve to 'come in'.

"You wanted to see me Professor?" he asked.

"Yes, please have a seat Steve."

I waited till the tall dark haired young man took a seat in front of my desk. I caught him looking at my chest a few times, which wasn't surprising since my nipples were rock hard from the video and finger play.

"I called you in today to discuss your test score. It was quite low," I began.

"Yes, I'm actually thinking about dropping your class. I need A's to get into physical therapy school and after this test I don't think that is possible anymore."

"I see, what would you say if we came to an agreement so that you got that 'A' you needed?"

"What kind of agreement?" he asked like most of them always do.

"I'm doing some research on the male reproductive system. I need volunteers for samples, videos and feedback for my study. Your help would be greatly appreciated and would be rewarded with extra points to make up for previously bad scores. Would you be interested in something like that?"

"Umm, maybe... what kind of samples... what exactly do I have to do?" he asked and shifted in his seat.

"It's easy really. This year I'm studying the male ejaculation, volume, force, external stimulation, refractory period, that sort of thing.. Basically I would give you a small camcorder for the semester with which you would record yourself ejaculating as well as capturing the semen for volume records."

His eyes got wide and he turned a shade of red from embarrassment.

"It's all very scientific I assure you. It's entirely up to you Steve if you wish to participate."

"Well, okay I guess."

"Excellent, to get started I need to ask you a few questions. Don't be embarrassed and please answer truthfully for the validity of my research."

"Alright."

I pulled out a notebook and began my questions. "Now, are you sexual active? Do you have a girlfriend in which you have intercourse with?"

"No, not right now," he answered.

"Actually that's perfect; it will be easier to limit the variables that way. Now, how many times a week do you masturbate, would you say?"

He shifted in his seat again and looked very awkward. I smiled pleasantly and acted as professional as I could until he answered.

"Well... three or four I think. I don't really keep track."

"I see... from now on you will. You'll need to record each occurrence. The camcorder will show me the day, and time but you must remember to record each ejaculation for the study to be accurate. Also it is imperative you collect as much of the ejaculate as possible. I have a kit to make that easier."

"What about using a condom, I could just bring that in righ..."

"No!" I interrupted him, making him jump in his seat. "I'm sorry Steve, you can't use a condom because part of the study involves velocity and force of expulsion. I use the tapes time signatures to record how fast the semen travels upon ejaculation and the amount of contractions. Condom use inhibits that completely."

"Okay, no condoms, got ya," he said.

I smiled and opened a drawer on my desk. Taking out a small duffel bag with the camera, several small plastic containers and a plunger syringe for sucking up the semen, I place them on my desk in front of him.

"Very well. Here's the camera and charger, this should be enough containers for the first week wouldn't you say? You can get more from either me or Tami if you run out but only drop off your samples to me. The syringe is self explanatory I think."

"No, not really? Why don't I just cum in the container?" he asked.

"You're not listening to what I've told you very well Steven. You can't ejaculate into the container because that will interfere with the cameras view? The best results from the past are using a hard flat surface to ejaculate on while the camera records the velocity and distance. Then use the syringe to suck up what's on the... table for instance, placing the contents into the containers. Also please use the syringe to extract any left inside your urethra and on your penis. Does that explain it better?" 

"Yes, Professor," he said squirming in his seat again. I could see the large lump in his pants from his hardening member. I was going to enjoy watching him masturbate for me.

"Very good. Any questions?"

"I don't think so," he replied, deeper red.

"Oh one more thing. The samples need to be fresh and given to me with the memory card soon after collection. I have many other replacement memory cards I'll swap you when you bring one in with the sample if you get low. Also please mark the samples with a number to keep them organized with the correct video if you have more than one on a memory card. The more samples the more points you'll get."

"Sounds good."

"Great, you're all set then. I look forward to working with you and receiving your first sample," I said standing up and shaking his hand. He picked up the duffle bag and left my office, trying to hide his erection.

The other appointments went very similar. All five boys agreed to help me with my research. It was a diverse group. The next, Rodney, had a girlfriend he said he had sex with almost everyday so I had to incorporate that with my plan. I suggested his girl friend hold the camera and film his ejaculation, but told him he would have to pull out and if he used a condom to have sex to remove it before he ejaculated. He said he had to run it by his girlfriend first but thought she would be okay with it if it was for school.

Daniel had no girlfriend and said he had never masturbated before. I didn't know if he was telling the truth or not but he said he was willing to try it as long as it was for extra credit. I gave him the name of a web site on male masturbation to help him learn what to do and to come see me if he had any problems.

Justin had a girlfriend but wasn't having sex with her yet. He said he masturbated twice a day at least and sometimes many more. I gave him extra containers and memory cards, making sure to tell him to label them correctly so I could put the right sample with the correct video.

The last boy was named Mike, a large football player who said he didn't have a specific girlfriend but was sexually active with multiple girls. He also masturbated during the week several times between the dates. I told him to make sure he captured the ejaculations from the self stimulation and to do his best to record his other episodes with the girls. He seemed to be the most excited and actually thought the camera would help him get more girls to have sex with him, since he would tell them it was for research and grade.

The appointments ended by lunch. Normally the first day I receive samples from all the boys because they get excited to video tape themselves ejaculating. I ate lunch in my office and waited for any to return.

*****

Justin was the first to come back. My lunch hour wasn't even over yet when he knocked on the door.

"Come in."

"Hi, Professor... I've got some samples for you," the sandy blond haired, blue eyed boy said.

"Excellent Justin, I'll get to working on them immediately. You said samples, how many?" I asked.

"Three right now, I have class so I thought I'd bring them in before hand."

"Impressive! Three so close together, you must have a short refractory time."

"A what?" he asked.

"Refractory period is the time between an ejaculation and when your penis engorges again. Tell me did you use any visual stimulation?"

"Oh, yeah well I get hard really quick again; sometimes it just stays hard in-between. To answer your question, I was online viewing porn for all three samples."

"Excellent, this is the kind of information I need. Any specifics you can tell me or put on the video would be great."

"Like, what do you mean?"

"Well, most of the time I can tell from the video the technique you used to stimulate ejaculation but sometimes letting me know about lotion, grip, visual stimulation used and things like that are very helpful."

"Oh... well okay. Here are the samples and all three are on this one memory card," he said handing me the three containers and card.

"Superb Justin, the more samples you supply the more points you'll get for extra credit."

"Cool," he said and left.

I wasted no time and took the first sample and popped the lid. Inside was a plentiful supply of fresh, very white semen. It smelled wonderful, turning me on instantly as I placed my nose to the top. I put the memory card in my computer and it popped up. Finding the first video that went with the number one sample I double clicked. Up popped Justin looking into the camera.

"Okay, this is Justin and my first attempt at recording for Biology 101 extra credit research program," he began on the screen.

He had his shirt on but he was naked from the waist down. The camera moved and I saw a quick glimpse of his laptop computer. He had porn up on the screen but it was too quick to see what he was looking at. He set the camera down on the table in front of him and I got a great view. His penis appeared to already be hard. It was nice, probably seven inches but I couldn't be sure on screen. He stood in front the table and began manipulating his shaft with his left hand. His right looked like it was on the computer, probably clicking on porn. He didn't use any lube, just moving the skin quickly up and down his shaft.

Suddenly I heard a woman's voice, screaming and moaning like she was being fucked. I assumed he was watching a porn video but couldn't see anything but his hand working his wonderful cock. It didn't take long at all, and before the sound of the video ended on his computer he moved forward and let out a huge burst of white semen toward the camera. I watched it splash on the desk followed by six others. He had built up quite the quantity with all the masturbating he does. I was very impressed. His penis throbbed and oozed out the rest of his load after he stopped stroking. He kept the camera on while he used the syringe to suck up the sample, placing it in the container before me. Then he used the syringe to suck out the extra from his slit and globs off his head. I was glued to the screen enjoying the sights and marveling at how hard his penis stayed even after such a load.

I picked up the sample and dipped my finger in it, bringing it to my mouth. I replayed the video and tasted his load while I watched his wonderful cock spew over and over on the clip as I kept rewinding it to the good part. The knock on my door made me jump and almost spill Justin's sample. Quickly I stopped the clip and put the lid back on the container. Fixing my clothes, I told the person to come in.

"Hey, Professor. I just wanted to let you know I was serious about this extra credit. I really want to get good grades so I brought you a sample to get started," Steve said walking to my desk.

He noticed the other three containers labeled with 1, 2 and 3.

"Great Steve, set it here away from the others so I don't get them mixed up."

"Wow, someone brought you three in one day?" he asked.

"Yeah, three in one hour actually," I said smiling.

"Shit! That's a lot."

"Yes it is. The more samples the more points though remember," I hinted..

"Right, okay well I've got to go," he said embarrassed, leaving before I could ask him any questions.

I watched him leave and picked up his memory card. They each had three cards so I didn't replace Justin's or Steve's yet. I ejected Justin's card and replaced it with Steve's, clicking on the clip once it came up. The images of a bathroom appeared. I could see Steve in the mirror because he was holding the camera in his hand. Pointing the camera down, I got the first view of his spectacular cock. I knew it was going to be big from the tent he made in his pants when he was in my office but I had no idea how big. From the look of it he had to be nine or even ten inches and very wide. He never spoke on camera and I didn't see any visual stimulation he was using either. He was sliding his hand up and down the shaft with some kind of lube, so his shaft was shiny and slippery looking.

I had a good feeling about this year's volunteers but Steve and Justin had already exceeded my expectations; Steve for his size and Justin for his potency and volume. I popped the lid on Steve's sample and peered in. Not near the amount as Justin but average. Good aroma and consistency. I watched the clip and sampled the taste, getting very turned on as Steve worked his mammoth cock before the camera. I heard a small groan from him right before a spurt of semen shot out about an inch, followed by another slightly longer. The rest just oozed out onto the sink as he stroked himself to completion. Not as eye catching as Justin but his cock size made up for it. Steve turned off the camera before cleaning up the sample so I missed him sucking it out and off his astonishing cock.

I was looking forward to taking my samples home where I could sit back, relax and not worry about a knock on the door. I watched Steve's clip a second time, licking my fingers clean but leaving some for later. Ejecting the memory card I put Justin's back in. I wanted to see how long it took his dick to get hard between clips. I opened the first and recorded the time shortly after he finished ejaculating and opened the next clip. I was shocked to see only three minutes had passed and he was either still hard or had engorged again.

"Justin again, ready for my second sample," I heard his voice over my computer speakers.

The camera was in a slightly different position. He was masturbating as the clip started with the exact same technique as before, which is very typical. Sounds of people having sex were already going as well when the clip started. I sat back in my chair and watched him stoke to the sounds of moaning and groaning from the porn stars. Justin actually warned me this time it was coming.

"Here we go!" he moaned, moving forward slightly so his cock was over the desk.

It erupted in a stunning display of white ejaculate. It wasn't as thick as before but shot out in all directions from the head of his penis. The next few spurts were more controlled, landing on the desk in front of the camera.

"Oh shit! That's going to be hard to collect," I heard him say about the first explosion, as he continued to stroke to the end.

The kid sure had a libido! His output was staggering and the fact that he was able to climax like that so soon after the first had me very excited. This year was already turning out fabulous. I picked up the number 2 sample and peered inside. It wasn't as much as the first and not as white but he did a good job collecting what he could. I loved watching the boys suck the remains out of their dicks and was very pleased when they left the camera running to do so.

I was very curious now to see clip 3 and how much longer it took between two and three for him to ejaculate again. Opening it up, my mouth dropped open. I had never seen a kid this potent. Only five minutes had passed this time and he was hard and stroking again.

"This is sample number three from Justin," he said stroking furiously.

More porn played and a minute later he splattered the camera with cloudy white liquid.

"Oh fuck! Sorry about your camera Professor, I'll clean it off," I heard him say as I saw nothing but blurry white semen running down the lens.

I came in my pants for my fingers on my clit I was so turned on by this kid. The sample in container 3 was very runny and much cleaner than the other two but still quite large. The boy had my attention and I was overly impressed with him. As I came I gulped down the entire sample 3 loving the taste and slimy texture of Justin's third offering.

I never even heard Tami come in, never even recognized she was standing by the door until she yelped in surprise as she watched me swallow Justin's load and stick my tongue in to get more.

"Tami! Did you knock? How long have you been there?!" I asked, wiping my mouth and fixing my skirt.

"Long enough to know drinking the guy's semen while masturbating to their videos has nothing to do with research. You lied to me Professor."

"And you didn't knock, Tami. How dare you!"

"I think that is the least of your worries Professor," she said folding her arms and glaring at me.

Shit! This wasn't good. I normally don't get this involved at school, for this specific reason, but damn if Justin didn't have me turned on! Now Tami knows the truth, which will probably get me fired and banned from teaching anywhere in the country.

"Yes... well let's talk about this Tami. Please come in and have a seat."

She hesitated slightly but then I noticed her nipples were erect, she was turned on by what she had witnessed. I could use that to my advantage I thought. She crossed the room and sat down, looking at the samples on my desk.

"So none of this is for 'research' you just do this for your own jollies?" she asked.

"Yes... I'm sorry I lied to you but I didn't think I could tell you the truth."

"Which is?"

"I'm addicted to watching men ejaculate and collecting their semen for my own use," I unloaded.

"I see... my my Professor, quite the dark little secret you have. What am I to do with this information?" she jabbed.

I remained silent with my jaw clenched. I wanted to smack the little bitch for being so smug and busting me but I couldn't make her mad. She smiled, picked up one of Justin's samples and popped the lid. Looking in she swirled it around, looking back up at me.




Biology 101 Pt. 01



"How does he taste?" she asked.

My eyebrow raised and I smiled at her, "Delicious."

"Cum is much better warm, right out of the cock though," she said smiling at me and putting the lid back on.

I might have picked my TA well this year. 

"I warm it most the time but got carried away today," I said waiting to see where she was going with this.

"Who's is this?" she asked with the sample still in her hand.

"Justin's, he supplied three today in less than an hour from my appointment with him."

"Three? Wow very impressive, and so much," she said hefting the container for weight.

"Indeed, he's a rare one," I said watching her swirl my sample.

"I'll tell you what Emily," she said using my first name. "I'll keep your secret with a few stipulations."

"Go on," I said.

"I want a shining review from you for my assisting, Monday and Friday off completely and copies of all the videos," she smiled.

The last one took me by surprise. I was expecting the first two but for her to want videos of my volunteers made me curious about her.

"Copies? And why, may I ask, would you want that?" I asked with a grin.

"Well, it just so happens I enjoy a good juicy cock exploding as well. And I'm very curious to see what my fellow students have to offer."

"Okay, good to know. So we have a deal? You'll keep my secret if you're in on my 'research project' and I let you off those days?"

"Along with the glowing review yes, we have a deal Emily," she said setting Justin's sample down and holding her hand out for me to shake.

"Excellent Tami, I'll get your copies before you leave for the day."

She smiled, standing up and walking to the door. Before she left she turned back and spoke.

"Oh, one more thing... on Monday, every week, you and I will get together to watch the most recent videos and have sex. I'll get back to you with a time," she said leaving before I caught my breath.

I was pretty sure my TA was bisexual after that comment. Her proposition shocked and excited me. There wasn't much I could do about it. She had me right where she wanted. I hadn't had sex with a woman since my own years in college, but watching cocks explode on screen while eating the samples and having sex with a gorgeous young buxom blond was going to be unreal.

*****

I stayed in my office for most of the afternoon. Putting my samples in a mini refrigerator I have in my office. I copied the clips from Steve and Justin, moving them to my hard drive in new folders with their names and cleaning off the memory cards. I also made copies for Tami and put them on a flash drive I could continue to add to for her. I was still a little nervous she would rat me out so I made sure I did everything she said.

I finally had to leave my office to use the bathroom, taking the flash drive with me so I had something nice to give to Tami. She had set up her desk outside my office, to help with correcting papers and other types of clerical help. I opened the door and she was busily working on grading homework. She looked up with a knowing smile on her face.

"Your copies," I said handing her the flash drive. "I'm sure I don't need to tell you how important it is you don't share these with anyone else. If I go down you come with me now," I said as she took the drive.

"Don't worry Emily, my tongue is tamed until Monday when I unleash it on your pussy," she said making my mouth drop open.

"You'll love it trust me."

My body flushed and I quickly walked past her to the ladies room. When I got back Daniel was standing next to Tami's desk apparently waiting for me. He didn't have a sample I could see and I wondered what he wanted. He was the one that said he had never masturbated before. Maybe he was coming back to tell me he wasn't going to participate.

"Here she is... Professor, Daniel needs to talk to you about the research project," Tami said seeing me walking toward them.

"Very well, come in Daniel."

He took a seat and I sat behind my desk. He seemed nervous and fidgety. He was a nice looking young man, well dressed, short neat hair and a baby face for someone in college.

"What can I do for you Daniel?"

"I checked out the website you told me about," he said wringing his hands together.

"And did you perform one of the techniques displayed?" I asked.

"Umm... well not really Professor I didn't get the chance. You see I think I ejaculated in my shorts watching the demonstration videos."

"I see... are you gay Daniel?"

"I think so yes, does that mean I can't be part of the study now?"

"No Daniel, you can begin again tomorrow, just be prepared next time so the sample isn't wasted."

"Oh good, that's a relief I really need a good grade in this class. There's something else I'm worried about. I don't know if I really understand what to do. I mean the videos were okay but like I said I've never done that before."

"I think you might have a problem called premature ejaculation. Tell me, were you externally stimulating yourself to the videos or did you ejaculate spontaneously?"

"Spontaneously, I got an erection and it just happened. Can you help me Professor?"

"Yes... and since you are attracted to men I have the perfect thing to help build up your stamina. You see the more you practice the longer you'll begin to last."

"What's this 'perfect thing' to help me?" he asked curiously.

"You need someone to teach you how to manually stimulate your penis, someone that you're not attracted to, so you won't ejaculate too quickly. A woman, I'd suggest."

"A woman? Do you have someone in mind?" he asked looking very uncomfortable now.

"Excuse me for a second Daniel. I'll be right back," I said standing up and walking out of my office.

"Tami, will you please join Daniel and me inside my office?" I asked her when she looked up.

"Sure Emily," she said still using my first name because she knew she could get away with it.

Together we walked back into my office with Daniel waiting for us in the chair. I sat back down and offered Tami the chair next to Daniel.

"Daniel, Tami is aware of the study and as my TA is willing to help out students with their extra credit assignments. Correct Tami?"

"Sure thing Professor. What do you need?" Tami asked with her bubbly personality again.

"Daniel really wants to participate but is a novice in this specific area. He's looking for some assistance to teach him proper technique. Do you think you could help him with that?"

"Absolutely Professor, I'm glad to help."

"Daniel, what do you think about getting assistance from Tami?"

"Umm... I think that will be okay. Professor Burke left out a few things. I've been struggling with my sexuality for a while now Tami. But since viewing the web site on masturbation I've come to realize I prefer men. I also apparently have a problem with premature ejaculation. Professor seems to think you can help."

"I see... well then I'm the perfect choice to help you," Tami smiled at him.

"My thoughts exactly," I added.

"So when do we begin?" Tami asked.

"Daniel? What do you think?" I asked.

"Whenever, sooner the better so I can get the most points possible."

"How about now? Professor Burke can film why I demonstrate. That should count as your first sample. Right Professor?" Tami asked.

"If Daniel is okay with that then yes?" I responded getting very turned on and trying to hide it.

"Here? Right now?" he asked.

"Sure, I'll lock the door, no one will interrupt," Tami said getting up and walking to the door.

She locked it and returned, standing next to Daniels chair. I didn't rush him, letting him think about it and make a decision.

"Well... okay so what do you want me to do?" he asked.

"Excellent, let me get my extra camera first," I said opening my drawer.

I took out a camcorder, sample container and syringe. Clearing the front of my desk off I got the camera ready. I was trying to control my excitement, not move to rapidly, and keep my hands from shaking. 

"Right, now Daniel just pull down your pants and Tami will do the rest," I said.

He hesitated, looking between Tami and I. We both smiled pleasantly and stayed as professional as we could. Finally he felt comfortable enough and stood. I hit the record button quickly, not wanting to miss anything. He slowly undid his belt and let his pants drop to his ankles. He wasn't wearing underpants, which was a surprise. His penis looked tiny, all shriveled up receding back into his body from being nervous. Tami didn't need to be invited; she moved her chair to the side and sat down next to the standing young man.

"Now Daniel, I'm going to touch you to encourage blood flow to your penis. Don't be afraid to tell me if something doesn't feel good," Tami said reaching for his small member.

I kept the camera as still as I could as my heart raced, focused on his penis. The reaction was instant, as soon as Tami touched his penis it began to grow, and grow quickly. I was amazed at how big and hard it got compared to how it looked at first. He was fully erect in no time, easily six inches.

"You don't have any problem in gaining an erection, Daniel," Tami said.

"No, it get's hard all the time actually," he responded.

"Okay now you should probably move closer to the desk if premature ejaculation is a concern. I'm going to simulate your erection for release," Tami voiced.

My nipples were erect and my pussy flushed and damp. He had a wonderful penis once it was hard and having him right in front of me hard and throbbing was extremely erotic. He moved forward a few small steps until his penis was extending to the edge of my desk. Tami stood, moving slightly behind him. Reaching forward she placed her hand around the middle of his shaft but didn't move.

"Now without any lubrication the technique is to just move the skin up and down, to simulate the friction needed. Like this," she said stroking his penis a few times.

It caught both Tami and me off guard when his penis suddenly began to ejaculate, spurting in rapid succession six blasts of semen onto my desk. His contractions were the fastest I'd ever seen, pumping out his load in less than two seconds. It was a really good thing I started the camera so soon. It looked like his dick was on fast forward mode because a second shot of ejaculate was on its way out before the first hit my desk. They were long blasts as well, coming halfway across my desk toward me. It was all I could do not to drop the camera and start licking it up before it cooled.

"Oh my! Well okay then. Did you get that Professor?" Tami asked.

"Yes, luckily I did. Well Daniel... that confirms the premature problem, but what interests me the most is your contractions. I have never seen such powerful and close together contractions before."

Tami let go of his penis and sat back down in her chair. Her nipples were as hard as mine and I figured she was wet as well. I handed Daniel the plunger syringe and kept the camera running as he cleaned up his sample.

"Don't forget what's left in your penis," I said when he appeared to be about to pull up his pants without cleaning his head off.

My body was aroused fully as I watched him suck out his shaft. His penis remained hard while he did and he hadn't said a thing. He worked in silence sucking up what he could and placing it in the container for me. Once he was done he pulled up his pants and sat down again, still semi hard.

"Did that help Daniel?" I asked.

"A little yes, but it was so fast again. I can't control it! It just happens," he said seeming frustrated.

"Don't worry, we can work on that. This is what I want you to do. Using what Tami taught you I want you to take a sample as many times a day as you have time. Between classes, at lunch, whenever you find time, take a sample. The more you practice the better control you will gain."

"Okay Professor, I'll try."

"Good Daniel, and don't forget to record them."

"I won't, and thank you for letting me participate and for the help. Both of you," he said looking between us.

"Sure thing Daniel. If you have any questions or need additional assistance feel free to come see me anytime," Tami added.

"I will," he said, getting up and leaving.

As soon as he was gone I reached for the sample and popped the lid, taking a long deep breath of his fresh load. It was intoxicating, making me want to suck it down right then.

"I know a quick way to warm that up," Tami said watching me with my nose in the plastic container.

"Go on." I said.

She held out her hand for the container. I reluctantly gave it to her, not knowing what she was going to do. She placed the container between her legs, and before I knew it took her shirt and bra off right before my eyes. She had a stunning set of perfect breasts. Firm, round and at least a D cup. I was speechless as she sat back in the chair and poured my precious sample of Daniel onto her chest, dripping the semen all over her breasts and nipples that were hardening quickly. All my valuable semen was on her body and I must have had a surprised and shocked look on my face, because she spoke up as soon as she was done pouring.

"Well just don't sit there Emily, your sample is going to waste if you do."

The white liquid coating her breasts was a visual treat and I couldn't let Daniel's offering go unused, could I? Standing quickly I walked around my desk. I dipped my finger in the largest pool of semen, sampling it. She smiled up at me and I fell to my knees. From the lowest drip I worked up her stomach, licking the trails of salty liquid off her warm body until I got to her large breasts. I only hesitated for a few seconds before diving in to eat the rest. Using my tongue, I lapped up the semen off her round orbs and erect nipples. Then I started to suck, feasting on Daniel's sample and sucking every inch of Tami's breasts. She was right, it did warm up quickly.

My body was on fire sucking this tight blonde's breasts. My heart pounded in my chest as my body reacted to the semen as well as the taunt nipples and warm flesh under my mouth. She moaned a few times when I gave her nipples a good licking or nibble on purpose. I'll admit I got into it and continued to suck and lick her breasts long after the sample was gone.

"See, I told you it was better warm," Tami giggled as I tugged on her nipple one last time.

"Yes, very delicious," I said getting back to my feet.

"Don't worry Emily, I'll return the favor next Monday," she said replacing her bra.

I watched the sexy young bombshell get dressed, before leaving my office. I fell into my chair overcome with the events of the day. I didn't know if I could take an entire semester like this...



Biology 101 Pt. 02



Rodney and Mike never showed before I left for home. They were the guys with girlfriends so getting samples from them would probably come later. I packed up Steve's sample and the remaining two samples from Daniel as well as my own flash drive of videos. The others I had already eaten. Tami was gone when I stepped out of my office. She was quite the little vixen. I had more confidence in her not going public with my obsession since she seemed to be getting her own 'jollies' out of my research as well.

I couldn't wait to get home, get naked, power up a vibrator and masturbate to my clips while slowly enjoying the last three samples of the day. I really wanted to slow down Daniels incredible contractions and watch his ejaculation in slow motion. I was almost to my vehicle, daydreaming about slowing down and combining clips when I heard my name being called from behind. I turned and saw Rodney with a female student hurrying to catch up to me.

"Professor... we must have missed you in your office but we need to talk," Rodney said.

"Okay, what's this about?" I asked looking between him and the female.

She was cute, much shorter than Rodney with brown hair, blue eyes and a cute little body.

"This is Sara, my girlfriend. She's also in your Biology 101 class along with me."

"Hello Sara. What can I do for you two?"

"Well, we were wondering if we both could receive that extra credit for the ejaculation study. I mean if I help film Rod when we have sex or when I do other stuff to him can I get points for that as well?" Sara asked me.

"I'll tell you what... if you want points as well then I'll have to split them between the two of you so if you want more points you'll have to produce more samples," I explained.

"We can do that no problem!" Rodney burst out excited to have more sex.

"What about you Sara? Does that sound okay with you?" I asked.

"Okay, yeah sure. I'll help out and get Rod on film as he cums for the study as much as I can."

"Wonderful, then it's decided. I'll tell Tami to add you to the study and split the points per sample between the two of you."

"Great! Thanks Professor and here's our first sample and memory card," Sara said opening her bag and retrieving the container and card.

"You were waiting to give me this after you got approval? That makes sense I guess."

"Yeah, kinda. Anyway there ya go. We'll get more to you later," Sara said grabbing Rodney's hand and pulling him away.

I added the card and sample to my others, excited to see what they had given me. Good thing I lived close to the university, I was overly excited for this evening's fun to wait too long.

*****

I quickly ate a bowel of cold cereal for dinner and stripped off my clothing, before heading into my computer room. I plugged in my flash drive as well as the memory card from Rodney and Sara. Opening my drawer I retrieved a long and wide vibrator, resembling a porn stars cock. Setting it on the desk I first picked Sara and Rodney's clip since I hadn't seen it before.

A bedroom opened to my view, a girl's room obviously with the posters and decorations I saw. The picture jerked around, making me sick until it finally came to rest on Rodney. He was naked, keeling in front of a pair of women's legs I assumed were Sara's. I could only see his upper chest and face while his hands held her feet. He was thrusting forward, obviously making love to Sara.

"Oh yeah, that's perfect Rod! I guess this camera thing does add a little excitement!" I heard Sara's voice behind the camera.

"Remember, she wants video of me cumming so I'll have to pull out," he said between breaths. He seemed to be working hard.

"Yeah, okay, just do it on my stomach and I'll record it," Sara responded.

I heard no more talking but both of them moaned and increased their breathing until Rod warned Sara he was about to 'cum'. The camera dropped down from his face to his penis as he pulled out. I could see her stomach and shaved mound as Rodney stroked his penis over her. He wasn't using a condom so nothing to take off. His penis was wet and shiny from Sara's insides. From what I could tell he was average, around six inches. After only a few strokes a burst of semen shot toward the camera lens, splashing onto Sara's tight young stomach. She squealed in pleasure as it hit her, knocking the camera off Rodney for a split second.

She recovered to capture the remaining spurts of ejaculate. Oh how I loved these young men with their quantity and power! He made a good mess out of her body from what I could see before she turned off the camera. I replayed the part where he ejaculated and grabbed the vibrator. It went inside of my wet vagina easily, especially after all the excitement of the day. I turned the red knob on the end, sending deep vibrations through my body. I started the video over completely, beginning to thrust the toy in and out, synchronized to Rodney's movements on screen.

By the time he was ready to climax I was on the verge. The thing that pushed me over the edge was of course watching his wonderful engorged penis spew its load onto Sara's body again. My eyesight became blurry as a wave or orgasmic bliss took over, making me convulse and squirm in my chair. I held the vibrator in deep, bending it to hit just the right spot, climaxing in a rush of pleasure I'd waited all afternoon for.

My body felt weak and spent when the sensation lessened. Once I recovered I removed the coated vibrator, giving my pulsing vagina a break. I realized I had yet to open Rodney's sample. In my excitement and pleasure I completely forgot about his semen on the desk in front of me. I picked it up and popped the cap off. Peering in, I saw a good amount of runny semen. When I smelled it, it wasn't the pure manly semen I have come to expect. It had a different hint to it, which had to be Sara. Taking the sample off of her body must have tainted it, absorbing her body spray or lotion.

It reminded me of sucking and eating Daniel's sample off of Tami, stimulating me again with the memory. I licked my fingers and twisted my naked nipples, pretending Tami was sucking and nibbling on them. Tipping the container I poured a small amount of Rodney's sample on my right breast, rubbing it around with my finger. Lifting my large breast to my mouth I licked and sucked the semen off of my own nipple. My clitoris began to hum again, sending chills through my body as I treated the left nipple to the same treatment.

I saved most of his sample for later, closing the container and deciding it was time to edit my clips. Using the media software I opened each clip I received today. Editing out what I didn't want, I shortened the clips to just before ejaculation, during and slightly after as the boy finished himself off. Once I had all the clips edited I added them all together to play one after another. First I played them in real time and then copied the clip and slowed it down so I could watch each powerful spurt in slow motion, adding it to the real time portion.

Justin's amazing eruptions looked even better in slow motion, as the white ropes of semen extended out from his cock before splashing onto the table. I froze the frame a few times to take in the visual and glory of his power. Daniel's rapid spurts were so close together I had to slow them down twice as much as the other boys to make them look like they were all the same speed. I couldn't believe the rate his muscles constricted to fire the ejaculate out so quickly.

By the time I finished editing the clips and watched it a few times I was dripping wet again. Good thing I put a towel over my chair because I had made a mess. My long vibrating toy found itself deep inside once again while I watched my masterpiece looped over and over. I helped myself to the remaining samples while I watched and eased the toy in and out of my dripping pussy. I came each time I swallowed another gulp of ejaculate, timing my climax to match the memory of eating their semen.

By the time I had finished all the samples my entire body was sore from convulsing and squeezing the toy between my legs. Walking to my bedroom took some caution, since my legs were so wobbly from fatigue. I slept like a rock from all my efforts.

*****

When I got to my office the next day I had at least ten students standing outside my door. I saw Steve, Daniel, and Justin in the group. Tami's desk was empty. None of the students were being helped and then I realized it was Friday. She had asked for Friday off. Looks like I had to deal with homework questions and other things alone today. I had only an hour before class, and had planned on going over the material in my office before hand. Now I wasn't going to be able to.

"Hello everyone, sorry about the wait. Tami's going to be absent on Friday's for the rest of the semester. Since you didn't know this I'll help you today in what time we have and announce to the rest of the class that Fridays we will be unavailable now."

I opened my office door and turned back to the crowd, "Okay one at a time who was first?" I asked.

I helped the students as fast as I could, sometimes telling them I didn't have time to explain what they needed to know. Steve, Daniel and Justin hung back in the crowd. It seemed they just needed to deliver samples. I hoped I had time before class to view at least one. Finally I got rid of the last student not participating in my study. The boys came in one at a time and delivered their samples. Steve had one, Justin and three again and Daniel, the last to come in, had five! I was very impressed and had to give him more containers.

"So, it looks like you got the hang of it?" I asked him.

"Yeah, Tami's demonstration helped a lot. And you were right, by the forth and fifth time I controlled it better and lasted longer."

"That's great Daniel I'll take a look. You should get going now."

I had his card in the reader before the door closed, shaking with excitement. I looked at the clock and cursed, seeing I only had five minutes before class. I decided against opening the first clip, not wanting to get involved and be really late. I still had to put all the samples in my fridge and walk to class. Taking out the memory card I quickly stashed all nine containers in the fridge and rushed out the door, dreaming about when I could come back.

*****

Class seemed to drag on. It wasn't one of my best lectures since I was distracted as well as unprepared. Finally it was over but before I could leave more kids approached with questions. It wasn't until another half hour passed before I got to my office again. Mike the large football player, who had yet to provide a sample, was waiting for me.

"Come in Mike. Do you have a sample for me?"

"Not exactly Professor. I don't think I'm going to be able to participate."

"What? You seemed to be the most willing of the control group this year?" I said stunned.

"Well I was but it turns out suggesting filming sex wasn't as big a turn on to the girls as I thought. None of them would let me. Even when I told them it was for extra credit."

"Well, then I guess you'll just have to film your sessions alone."

"Yeah, about that. I kinda lied about masturbating. I don't have the time and desire really because of the girls and football practice. Is there something else I can do for extra credit?" he asked leaning over my desk with a sultry look.

"What did you have in mind Mike?" I asked taken aback slightly to his forwardness.

"It occurred to me that you might like what you see on these cameras you gave us. Maybe you have more interest in this study than pure science," he said slyly.

"What are you insinuating young man!" I said as upset as I could sound.

"You know what I'm saying Professor. I think you like watching your students jack off and shoot their cum on camera."

"How dare you! I assure you it is strictly for scientific purposes only!"

"Really? So if I were to take my big cock out right here and toss off onto your desk you would be disgusted? Or would you love it?" he smiled, undoing his belt.

My heart was racing. I don't know how he figured it out or who told him but he was on to me. I couldn't say a word as he dropped his pants and boxers. He grabbed his long member and began stoking it until it was hard and throbbing. He wasn't kidding about big. He was long and wide, matching his athletic body. He rivaled Steve's large penis and it was difficult to tell which was bigger since one was in real life and the other on screen. I couldn't take my eyes off of his amazing member. He worked it in his hand, stroking the skin over his head and then back again. My nipples hardened and I felt a gush of liquid drip from my stimulated vagina. 

"That's what I thought, you love it," he said since I didn't stop him and bit my lip watching him handle his member. "What do you say Professor? If I cum for you can that count for extra credit? Maybe if I cum in your mouth that will be worth even more."

Now I knew he had figured me out. But how? I couldn't resist his offer. Taking a fresh hot load directly in my mouth was the ultimate temptation. I still didn't have any words to respond.

"You better hurry and decide Professor. I'm getting close to splattering my load onto your desk," he said after another minute of stroking.

"To get an 'A' this semester you'll need to ejaculate in my mouth more than once. Especially with your terrible test score!" I said, letting him know he had me figured out.

"Fine with me. Maybe you can suck it out a few times as well," he said smiling and stroking at the same time.

I walked around my desk and sat down in the chair next to him. He turned, facing me and still stroking. His powerful aroma made me quiver as I got a strong whiff of his oozing cock. He put it right up to my face, bending it down horizontal.

"You better open up Professor, because here it comes!" he moaned.

His butt cheeks tightened up and the head of his member became shiny and purple right before his explosion. I opened my mouth just in time to accept the first burst down my throat. Exquisite! Untouched semen directly from the penis into my mouth was phenomenal. He moved forward, putting his wide engorged head into my mouth as more semen spurted out, filling my mouth with exquisite bliss. He moaned as he stroked himself through to the end, giving me a wonderful amount of fresh semen to enjoy.

"See, wasn't that better than watching a video Professor?"

"Mmm, yes much, Mike," I said after swallowing the last of his load I sucked out of his cock.

"So we have a deal then? You get my loads and I get my 'A'?"

"Yes, but it has to be once a week until the end of the semester. Friday should do just fine. I'll expect you every Friday after class. Oh and I don't think I have to tell you to keep this between you and I or the deals off."

"You don't. It works perfect for me. Friday's it is. I'll return the camera and supplies next week when I let you suck me to climax," he said doing up his pants and grinning.

I watched him leave from the chair I was in. My heart was still pounding in my chest, too overwhelmed from the experience to stand. At that moment I was too giddy to realize this could come back to bite me in the ass. Not only did Tami know my secret but now a student did as well. His taste was still in my mouth. I went into a daze, thinking about his load spurting down my throat and on my tongue until the knock on my door startled me. Finally standing, I walked to my own chair behind my desk and told the person to come in.

"Hello Sara, what can I do for you?"

"I'm just dropping off another couple of samples from Rod and I."

"I didn't see you in class this morning?" I said wondering.

"Yeah, sorry. We were kind of busy," she said smiling.

"Oh... well at least it was for a good cause," I grinned back.

"A-huh, you'll notice in the second one I kind of didn't take Rod out of my mouth quick enough so part of the sample released in my mouth. I hope it will still count."

"I'll take a look Sara, I'm sure I can work with it," I said knowing just how hard it was to not let the guy finish in my mouth.

"Cool! Thanks Professor," she said placing the samples and card on my desk.

I envied her young tight body as I watched her leave. I put the two samples in the fridge with the others. I had had my fill of semen for a bit. So many clips to choose from and not much time before lunch. Sara had me curious about her clips so I put her and Rodney's card in first.

As the first clip started my envy of her body only increased. Rodney obviously had the camera this time and Sara was on top of him riding him with enthusiasm. He had the camera trained on her small perfectly round breasts. The nipples were erect and her eyes were closed as she enjoyed the member sliding in and out of her. He lowered the camera so I could see his glistening member as she rose up and back down. She didn't have a flaw on her perfect skin, no rolls of fat, no cellulite, just a perfectly toned young body for Rodney to enjoy. Oh to be young again! No matter how much you exercise and watch what you eat, time and gravity take their toll. Don't get me wrong I look good for a woman in her forties but how do you compete with nineteen or twenty year olds?

The camera went back up her body. She opened her eyes and looked down at Rodney and the camera.

"Are you filming this?" she asked.

"Maybe?" he said.

"Why? The study is just for ejaculation. Professor Burke's not going to want to watch us having sex as well. Turn it off."

"It's fun?" he complained.

"Turn it off Rod!" she said louder and stopped moving on his shaft.

"Fine," was the last thing he said before it cut off.

The clip start again with Rodney still on his back and Sara stoking his penis. From what I could gather she had ridden him until he was ready to ejaculate, then she hopped off and finished him off with her hand. He had the camera focused on his hard wet member. It only took a few strokes from Sara before his penis erupted into the air. Semen splattered on his stomach right before another stream shot into the air. Sara stroked him powerfully until the remaining globs oozed out down his shaft and over her hand.

"Did you get it?" she asked.

"A-huh I think so. Damn that felt good."

"Kinda sucks for me. I like when you cum inside and we climax together," she said letting go of his covered member. It fell onto his stomach into a puddle of white thick semen. She cleaned off her hand on his hip and sat next to him looking at the mess. Rodney had the camera on her body.

"Are you going to clean me up?" Rodney asked.

"No, do it yourself."

"Well at least get the container and syringe. I can't exactly move," he complained.

"Fine, turn the stupid camera off."

He had it on her perky little breasts again, admiring her body but the expression on her face made him turn it off. I laughed to myself and ran it back to watch him ejaculate again. It was interesting to watch his body convulse, spasm, and erupt under Sara's stroking. It seemed different than when the boys do it to themselves. This made sense because Rodney wouldn't be in control as much while she manipulated his member. 

I studied the ejaculation a few more times before starting the second clip they had produced. The time stamp was almost an hour later. The camera appeared to be sitting on a table filming Sara giving Rodney a blowjob. She was fully dressed as was he except for his pants being around his thighs. Sara looked like she was really enjoying sucking his member, taking him deep and grabbing his tight butt. She alternated between deep and just sucking his head. She used her hand a couple of times, stroking his shaft while licking the underside of his purple head.

The clip was much longer than I expected, I guess they had started it before hand because neither one of them held the camera. She got more aggressive as time went by, working hard to get Rodney to ejaculate. His moaning got louder as his ass got tighter. The young woman really knew how to give head. Rodney's shaft was coated in a foamy mixture of her saliva and his pre-ejaculate. She never stopped the stimulations. She was sucking, stroking or bobbing on his penis with no rest in-between. I could tell she enjoyed it and did it for fun before this study. 




Biology 101 Pt. 02



"Almost there..." he warned her.

She didn't stop with his cock deep in her mouth, stroking with just her index finger and thumb near the base.

"Sara! I'm going to blow," he cautioned again.

She not only kept going she increased her speed on his shaft with her hand, and tightened her grip on his shaft with her mouth.

"I can't hold it!" he cried as his muscles constricted and I'm sure a blast of semen shot into Sara's mouth.

She quickly took him out. He turned toward the desk and camera. She stroked him to completion with only the first spurt I saw traveling any real distance. The rest just ran out of his hole and dripped onto the table. When I watched it again I kept my eye on Sara. I defiantly saw her swallow the first spurt of semen she had told me about. I couldn't blame her.

"Why didn't you take me out? I came in your mouth that first shot," he asked once she had let go of his oozing member.

"Sorry, I couldn't help myself. This isn't fair; I'm not getting to do what I usually like."

"It's going to help our grades. And it's not like forever. I hope Professor Burke accepts this one. She was pretty specific in wanting to see how fast and far I can shoot. We need to make everyone count since she's splitting the points between us."

"I know, I'll try not to do that again," she said getting to her feet and turning the camera off. 

I had to chuckle to myself again. This 'little study' had young Sara a little flustered. I loved it. I contemplated not accepting the sample, hopefully making her do another one. I didn't think I would make her mad enough to quit and messing with her would be fun.

I watched the clip again. The ejaculation was kind of a let down with all that sucking and manipulating she went through. The closer I studied it I was under the impression he had spurted twice in her mouth. I distinctly saw his cock contract twice with her mouth around it. No wonder he didn't have much force once she took him out. I'm sure she loved feeling his penis convulse and spurt though, just like I had with Mike.

I spent all the time I had before lunch and needed to go. I was meeting with the department faculty today so I couldn't eat in my office and watch more clips. I still had one of Steve, three from Justin and the amazing five from Daniel to watch.

*****

I wasn't much use in the meeting. Daydreaming about Mike's huge cock ejaculating in my mouth occupied my mind. The head of the department stopped asking me my opinion on items because it took him two or three times to get my attention. He talked to me after the meeting and I told him I was just distracted and a little stressed right now. He didn't think much of it.

Thankfully I remembered to tell the class Tami wasn't available for questions on Friday so when I got back to my office there weren't any students waiting for me. Unlocking my computer I put Steve's clip in first. His large member made my mouth water and my clitoris tingle. He was already rock hard and oozing when the clip started. Who knows how long he had been manipulating it before he started the camera. He ejaculated less than a minute later onto the bathroom sink he uses to film himself. Nothing too spectacular in his orgasm, his first spurt traveled less than three inches and the remaining quantity dribbled out of the end of his massive penis. He turned the camera off quickly after he was finished. The clip was only forty-six seconds in length. He didn't seem too interested in the study at all.

Justin was a completely different story. He introduced himself again and even knew this was sample number four for my extra credit study. He had porn playing again and stroked his seven inch member to the sounds of a screaming porn star, telling someone to fuck her ass harder. Justin even moaned for the camera and told me when he was about to ejaculate. I swear this kid had inhuman potency. Yesterday he supplied me with three samples with time stamps that were incredibly close together. I never imagined he could do it two days in a row but I was pleasantly incorrect. His volume and velocity were the same. Even the time between clips was almost identical. I got the other clips out to compare, playing them simultaneously next to each other on the screen. It was almost like watching the same clip except his clothes were different and the sounds of the porn had changed.

My mouth was wide open watching this boy perform on screen and perform he did. I think he was really enjoying himself, getting into it more than I've seen another student. One of the best parts about Justin was he didn't turn off the camera to clean up the semen, so I got to watch him suck the load out of his hardened shaft while he explained what he was doing. He seemed to love to talk to the camera, to tell me what he was watching, when he was going to ejaculate and what sample he was doing.

I had so much fun watching and comparing his clips from last time I spent the rest of the afternoon on Justin's clips. It was time to go home before I knew it. I packed up my new samples, memory cards and headed for my car. I still hadn't watched one clip of Daniel's. It was going to be another long and exhausting evening.

*****

"Hi, it's me, Daniel. I'm turning this on before I even start incase I can't control it again," Daniel said as I started his first clip.

I had eaten, sitting naked in my chair again with my trusty vibrator sitting on the desk in front of me. Daniel was in a bathroom, I could see two towels behind him. He was completely naked as far as I could tell and had a hard throbbing erection. He really didn't' have difficulty getting hard, especially if he hadn't even touched himself yet. It looked like he had set the camera down on the counter. I couldn't see his face, just the middle of his chest down to his erect penis. He was skinny with not much muscle definition and no hair on his chest.

"Okay here I go," he said reaching down with his right hand.

He grasped his shaft like Tami had taught him and gave it a downward stroke. Already his scrotum was so tight around his shaft his testes didn't look like two individual balls, just a mound of flesh under his engorged shaft. Another stroke was all it took.

"Oh no I can't stop!" he exclaimed spurting in such rapid succession again he was done in less time than Steve.

He had more output than Steve's big penis and further distance but it was so blinding fast I couldn't even count how many as they splashed onto the counter in front of him. He definitely had a premature ejaculation problem. His contractions were so impressive my mouth dropped open again and I felt my vagina flood with secretions. His member did start to soften almost immediately which I found surprising. He turned off the clip to clean up the mess. 



"Daniel again, I'm going to try again since I got another erection," the second clip started.

The clock at the bottom said fifteen minutes had passed. He was in the bathroom again this time with a shirt on and fully erect. He changed the angle of the camera this time. It was more to the side now instead of straight on. Four strokes later and he ejaculated again. It wasn't as thick or white but his contractions were just as fast, sending the semen out twice the length of his penis onto the counter. Another impressive display.

The next clip was a half hour later and he lasted fifteen strokes of his hand on his shaft before ejaculation. The next was another half hour and he stroked a good minute before his amazing contractions rocked his body sending clear sprays of semen onto the counter. It looked more like urine than semen it was so clear and thin. The fifth and final clip began. He was hard again and an hour had passed since the forth clip. He lasted a whopping five minutes. Moaning and stroking his member with much effort. Small spurts of clear semen left his member upon climax. They didn't travel the same distance but they did exit with the same rapid succession.

I had all five samples on my desk. Opening them I poured two through five into one. It was an impressive amount of male ejaculate. Turning on my vibrator I shoved it up my vagina and pinned it there with my legs, letting the deep vibrations course through me. I poured the entire contents into my mouth and swirled it around savoring the taste and texture. I let it sit in my mouth while I enjoyed the vibrator between my legs. About a minute later I emptied my mouth back into the container, setting it back on the desk. His aftertaste remained in my mouth while I treated myself to a good pounding with my toy.

I added all of his clips to the player and looped it. Watching them while I played with my engorged clitoris and shoved my toy in and out I was about to orgasm when my doorbell rang. I planned on ignoring it but whoever it was rang again and again like it was urgent. The distraction killed my build up so I reluctantly pulled my toy out, set it on the desk and grabbed my robe.

They were still ringing the bell when I tore open the door.

"Catch you at a bad time, Emily," Tami said with a smile on her face.

"Tami? What are you doing here?"

"Came to get my daily videos, I didn't want to wait until Monday."

"What? Now?" I asked upset.

"Yep, here is my flash drive. I'll wait," she said not caring how I felt or what she interrupted.

"Fine. Stay here, I'll be right back," I said taking the drive and letting her into my foyer.

I hurried into my computer room and started collecting the clips onto her drive while she talked to me from my foyer about my house. I was almost done when her voice came from the doorway of my study. She had followed me without my permission.

"Having a good time in here I see," she said nodding toward my drying vibrator.

"I told you to stay by the door!" I said grabbing the toy and putting it quickly in the drawer.

"Oh don't be such a prude. What else would you be doing with the boy's clips? I'll admit watching them turns me on as well. I came five times last night watching them. Granted, Jessica was eating me during but that's beside the point?"

"What! Who's Jessica? Did you show her the clips?!" I screamed.

"Settle down Professor. She doesn't know where I got them. She just thought they were amateur clips of hot guys off the internet. Our little secret is safe.

"Tami, you are taking this arrangement too far!"

"And what are you going to do about it, Emily?"

I didn't respond besides glaring.

"That's what I thought. You just keep you end of the deal and everything will be fine. So how many clips did we get today?"

"Well, after you left some interesting things happened," I began.

I told her about Rodney and Sara but left out Mike ejaculating in my mouth. I just told her he dropped out of the study. I then told her about all the clips since I last saw her. She was very excited, mostly about seeing Rodney and Sara having sex. She was also pleased to hear about Daniel and the improvements he made after five tries.

"Mmm, sounds delicious. I'm getting all turned on thinking about it," she said rubbing her tight voluptuous body in front of me. "Too bad about Mike I hear he has a nice cock."

I walked around my desk and handed her the drive, "It's time for you to go Tami."

"I can wait until Monday if you can. I told you I'd get back with you on a time. Do you want to meet here or at the school?" she asked.

"Since you know where I live, I think here would be better, so we aren't interrupted."

Sounds good to me, how does six sound? I can't wait to make you cum," she said, sending anticipation chills through my clit.

"I'll be here. You should really be going," I said trying to sound confident.

Vaginal secretions were running down my leg from my interrupted orgasm. It was really tempting to let her stay. Maybe she would treat me to the same pleasures this Jessica had. I could scarcely imagine being feasted on while watching and eating my research. It was a struggle to tell her no.

"Okay Emily, I'll go if you really want me to." 

"That would be best," I said, kicking myself as the words left.

She didn't hesitate, turning and walking to the front door. I followed her, closing the door behind her tight young ass.    

I fell back on the closed door, sighing in sexual frustration as well as the control this little vixen had on me. I quickly returned to my study and vibrator but even after hours of sucking down samples and bringing myself to multiple orgasms I still felt sexually unfulfilled. The anticipation of Monday was driving me crazy. There was just something about Tami's attitude and incredible body that had me thinking about and lusting after her.

Saturday and Sunday crawled by, I had depleted my store of fresh cum on Friday night, so I had nothing to sample while I watched my clips. Monday would prove very interesting considering the two days for the boys to collect samples, and my date with Tami. I didn't sleep much Sunday night from the excitement of it all.

*****

I remembered to tell the class on Friday that Tami wouldn't be available on Mondays as well as Fridays anymore. When I arrived at my office the only students there were my extra credit boys, all of them that are. Mike was absent of course since he isn't participating in the same way. One at a time they walked in with their backpacks and unloaded their samples and cards from the weekend.

Talk about the mother load. I don't think these boys did anything besides masturbate for both days, nonstop. Steve had six, which was a lot for him. Rodney produced seven, so he and Sara must have been busy. Daniel, my pre-ejaculation case had a whopping ten separate samples, but Justin topped everyone with fifteen!

My small fridge was chuck full with man juice, by the time the last boy emptied his back pack. I was stunned by Justin actually, fifteen in two days? I didn't think that was possible. When he stood there in front of my desk and continued to pull sample after sample I didn't know what to say when he was done. He basically smiled at me and left.

Once I cleared off the samples I had all the cards on my desk and planned ahead of time for this very thing. Granted I wasn't expecting this much but I knew it would be impressive. With that thought I prepared my lessons for today on Sunday so I had time before class to view as many new ones as I could. Everyone but Justin had one memory card with all their clips on it but I guess Justin had filled up one and had to go to another. This made sense since he liked to perform and take longer to film even the clean up. I couldn't resist and put his first card in to start with. Needless to say I was late to class.

I was so turned on after watching his clips I had to take off my panties and walk to class commando so the wetness didn't soak my pants. The boy should drop out of college and become a porn star, because he knows how to perform for the camera. Not only were his collection of ejaculations impressive he came up with clever views and a myriad of ways to position himself while ejaculating. Top view, side view, bottom view, you name it he filmed it. He masturbated standing, sitting, lying down, kneeling, on his side and even upside down hanging from an exercise bar! Each clip got more involved as I went through the fifteen. Again, I had no idea how he was able to recuperate so quickly and have such volume.

During class I kept getting distracted thinking about it and I think Mike clued in on it because he showed up at my door knocking just as I was going to sit down in my office chair.

"What can I do for you Mike?" I asked as he entered.

"I know it's not Friday yet but I didn't think you would mind, and you said I needed all the points I could get."

I was taken aback but covered it well, "Umm, now?"

"Why not, I'll even let you suck me if you want."

"Lock the door, Mike," I said.

He grinned, locked the door and came toward me already undoing his pants. I sat down in my chair and he came around my desk, fishing his large half erect penis out of his pants. I didn't hesitate and grabbed it as soon as he was within reach. Justin's videos had me so hot and bothered I want fresh cum more than anything.

Stroking him to full power I admired his enormous member before taking the head in my mouth. He was so wide and long it almost hurt to suck him but just almost. He moaned loudly as another few inches entered my mouth, and I used my tongue underneath his head. He tasted wonderful. The texture of his shaft and head caused my body to react in stimulating ways. My clit tingled and my nipples hardened as I stroked the base of his cock, sucking what I could manage in my mouth.

"Oh fuck yeah Professor, you really know how to suck a cock," he said, putting his hands on the back of my head. 

I ignored his language, focused on his amazing shaft and pulsing head. His pre-cum kept appearing out of his slit, to blend with my saliva. It tasted fantastic, making my body flush with further pleasure. He began to moan louder and I felt his shaft harden under my constant stroking and sucking. I was after one thing and one thing only... his semen. I had no purpose to delay his ejaculation so I didn't slow or change anything.

Firmer and larger his cock continued to pulse until he, without warning, ejaculated in my mouth, sending a burst of hot semen down my throat. Leaving his head in I stroked him to completion, keeping all he had to offer in my mouth as he added to it with each contraction. I was in heaven. I considered taking a man's load orally the most erotic of all sex acts and I climaxed spontaneously while he filled my mouth with the nectar of my desire.

He bucked and squirmed as I stroked and sucked every drop from his head. When I couldn't get anymore out I let him go and pulled away with a mouthful of semen. In one glorious gulp I swallowed the entire amount.

"Holy fuck! That was unbelievable! I've never had a woman suck me like that before and the swallow. She was right, you do..." he cut off.

"What? What did you say? Who's she! What did 'she' tell you?" I said getting out of my chair.

"Nothing... shit, it's nothing," he backpedaled.

"No Mike, it's not nothing, who told you I love to eat semen? I know someone did. Who was it?"

"I can't say, she'll kill me, and not let me..." he stopped again.

"Not let you what?"

"The deal was if I kept this a secret she would let me do anal with her. If she finds out I told you who she is I'll miss out on that. Do you have any idea how hard it is to get a girl to take my cock in her ass? It's virtually impossible."

"I can see that, you are huge after all."

"Exactly, so I'm not giving her up, even if you fail me. I'll take the anal before the A." he smiled.

It had to be Tami; she was the only one that knew. And she was probably the only girl I knew crazy enough to let Mike sodomize her. Maybe he didn't have to tell me and I could get it out of her tonight.

"Fine, Mike, don't tell me I wouldn't want you to miss out on something so important to you. I just hope this person actually goes through with it."

"So we're good, I'll get my A."

"Oh yes we're good Mike, you keep coming back and giving me what I love and you'll get what you want."

"Thanks Professor, I should go," he said maneuvering his large penis back into his pants and walking out of my office.

His after taste was in my mouth. I sat back in my chair savoring the memory and flavor. With the lack of panties I had soaked my pants with my orgasm. It was worth it, but I would just have to let it dry before my next class. I copied the many clips onto a flash drive to take home for tonight's lesbian tirade, deciding not to watch any more so I could dry up and the clips would be fresh and new for Tami and I to enjoy.

*****

The samples in my duffle back, rattled together, making an odd noise as I walked to my car. Getting home in time to quickly eat before six o'clock came I was very excited and eager for Tami to show up. I tried to resist watching any clips but the longer I waited for her the urges increased.




Biology 101 Pt. 02



She was late, I expected her to be prompt, not because I was a teacher but because I figured she'd be as excited as I was. I couldn't stand it anymore, telling myself if 6:30 came and she still wasn't here, I would start without her.

I hit play just as the 29 turned to 30. I'm really glad I did. Steve's huge penis filled the screen, he seemed to be getting more adventurous, or at least with the camera. He had it focused close up, so the only thing I could see was his long shaft, head and a little space in front of it. He looked delicious, hard and oozing with large veins giving definition to his shaft. I opened my robe, spread my legs, and licked my finger. With my eyes glued to the throbbing member being stroked on screen I fingered my clitoris with a circular motion. It engorged quickly, becoming very sensitive to my teasing. Steve's head turned purple and enlarged, erupting with thick white globs of semen. I felt my body constrict as I viewed the convulsing penis squeeze his load out onto the counter.

The doorbell ringing made me jump with surprise, I was so tuned into what I was doing and seeing it startled me. Stopping the clip, fixing my robe I stood up to answer the door.

"You're late," I said throwing it open.

What I saw on my porch caused me to stop what I was going to say and grab my robe tighter around my body. Tami was standing with a smile on her face and next to her was Mike.

"Mike tells me you wanted to know who tipped him off on your secret. I brought him with me to make sure he didn't tell you," Tami said.

"He didn't, but I assumed it was you."

"That's good; I wouldn't want him to miss out on something."

"Now what? Is he leaving?" I asked.

"I was thinking he could join us if he was a good boy," Tami said. "Are you okay with that Professor?" she asked.

"I thought this was between you and me. What about the clips?"

"You two can watch them I'll just stay busy another way," Mike grinned.

I had to admit the idea had me intrigued and a good hard ten inch penis could be a very nice addition. Moving out of the way I asked them to come in. I could tell Tami controlled the relationship, if you could call it that. Mike looked like an obedient puppy next to her, granted he was a very large puppy but still a puppy.

"So where do we want to do this?" Tami asked.

"Anywhere, I can bring my notebook computer wherever if we need more room."

"With Mike we might need the room, good point," she snickered. "This front room looks good. With plenty of towels we shouldn't hurt your furniture to much."

"Fine, I'll get the towels and my computer. You two make yourselves comfortable."

They took me very literally on the comfortable thing, because by the time I got back with towels, samples and my computer, Tami was sucking Mike's large member while he sat on the couch. I stopped and watched from the hall, admiring the visual from a distance. She must have zero gag reflex because she was taking his wide and long penis much further down her throat than I thought possible. When I sucked him I wasn't near as deep as her. She had her shirt off but her bra, supporting her huge firm breasts was still on. Mike had his shirt off, pants around his ankles but his hardened shaft extended out of the fly on his boxers. 

Watching for a few more seconds I joined them, setting everything in my arms on the coffee table. I sat next to Mike, enjoying the sounds and sights of Tami sucking him.

"There's plenty of him to go around, Professor," she said taking his member from her mouth.

I leaned over, kissed his muscled chest and moved lower while Tami tugged his boxers off. She started sucking his testicles so I took the opportunity to put his head in my mouth. I could taste Tami's peppermint gum on his head and shaft, mixed with his salty pre-cum. It was very erotic, making me aroused quickly. She pulled back and unclipped her bra, letting her breasts out in the open. They were gorgeous, creamy white with light pink areolas and capped off with darker pink nipples that were hardening as I looked sideways with Mike in my mouth.

She left Mike, finding my legs under my robe. She untied it, opening the robe to get to what she wanted. I adjusted myself so she could get to my wet folds easier. She dove right in, licking from my ass to my clitoris, spreading me wide open and pausing on my nub. Her peppermint gum tingled my insides, I moaned loud on the penis in my mouth and sucked harder as she flicked my clit with her tongue.

There wasn't much better than sucking a large penis and getting eaten by a pro at the same time. I didn't want it to ever end but Mike had other plans for his dick, mainly Tami's tight little ass, I was sure. He moved away from me, pulling his member from my mouth with a pop. I sighed in frustration but there was no way to stop him. He went right after the bombshell still feasting on my vagina and clitoris. Mike had her panties off and was fingering her vagina in no time. She was on her knees giving him perfect access to both of her holes. I watched him spread her juice around her lips and to her tight rosebud hole.

Ever so slowly he inserted his index finger into her bum, causing her to moan loud into my dripping womanhood. She appeared to like her bottom penetrated. He forced it in further and the pleasure apparently was so good she stopped licking me to enjoy it.

"That's it... oh yeah fuck my tight ass with your finger!" she screamed.

I was too far away from my computer to grab it but Mike wasn't. Interrupting his play time I told him to hand it to me because Tami's attention was now on what Mike was doing to her. He handed me the computer, keeping his finger deep in Tami. Setting the laptop on the sofa next to me I found the next clip of Steve's to enjoy. Tami looked over and watched as well, finally remembering to play with me. She used her fingers this time so she could watch the clip and enjoy the finger sliding in and out of her butt.

"Put your cock in my pussy and finger my ass!" she instructed him.

He didn't hesitate. I turned from the computer to watch him take hold of his mammoth penis; slide it up and down her wet lips a few times before entering her in one smooth motion. The reaction from Tami was incredible, she began to pant, shudder and seemed to be climaxing upon his full length disappearing. Small whimpers came from her lips and her nipples were rock hard. Again she stopped playing with me to enjoy the large penis inside her body.

With his withdrawal he inserted his thumb into her butt and pushed his rod back into her, causing another intense reaction from the vixen. It was too hot and right in front of me to ignore. Even the exploding penis on the screen paled in comparison to the visual of Mike's huge wet rod driving in and out of Tami's incredible body. I left the laptop on the couch and knelt next to the couple making love to get a better look.

It was an awesome visual. I watched her lips, stretched tight around his shaft, cling to his member as he slowly slid in and out. His thumb, pressed deep inside her bum, wiggled back and forth to the rhythm of his thrusts. She had her arms up on the sofa and her knees on my carpet. Her head was down in a muffled scream each time he slammed back into her. I began fingering my nipples and clit as I watched them go at it. Mike watched me and reached out with his hand for my right breast. He hesitated, looking at me for permission first. I smiled and he grabbed and squeezed.

He had Tami at orgasm a minute later, convulsing and screaming her shouts of pleasure. His penis was covered in her juices and only got worse as she shuttered under his thrusts.

"Do her in the butt, this is your chance," I whispered in his ear.

There was plenty of lube now and she was so turned on I was confident she could handle it. His eyes got wide but he quickly decided to try. Pulling out of her, I smeared her juice around her anal opening and stuck two fingers in with ease. She was ready. I nodded to Mike. I could tell from the hardness of his penis he was excited, it was almost against his tummy, throbbing and purple. He had a difficult time bending it down enough to enter her but managed. She didn't say a word as his bulbous head slid into her tight hole with relative ease. He froze, allowing her to adjust before sending two or three more inches in.

The visual treat of his long shaft halfway in her butt was the best thing I've ever seen in real life. She amazed me and took more without even a whimper. Inch after inch disappeared until his balls were up against her wide open pussy. She had him all; every delicious inch of his manhood was buried in her bowels. He held it in, with a look of utter bliss on his face.

"Oh my, he likes your tight butt Tami," I said laughing.

"He better, he's done nothing but talk about it."

When he began to pull out the expression on his face turned to amazement I learned why by what he said.

"Fuck it's so tight, and grabbing at my shaft!"

He left his head in and proceeded to slowly insert his length back into Tami.

"That's it Mike, fuck my tight ass! Give it to me!" she screamed, feeling him moving back in.

He sped up, pulling out faster and slamming his hard shaft back in over and over until Tami began to scream. I didn't think he could last long at this intensity and I was right because before five minutes went by he was saying he was going to blow.

"I want your load, ejaculate in my mouth," I said watching him thrust in again.

He looked at me and smiled, giving Tami a few more thrusts before pulling out and grabbing his tool. He moved to the left and I opened my mouth to receive his first blast of semen. His force took me back, almost gagging me. He was obviously excited about anal sex because his power and volume was double from the last time he filled my mouth full. It was too much, seeping out the sides of my mouth to run down my face and drip onto my breasts. More continued to spurt out of his shaft as Tami moved next to me. He pulled away from my mouth and shoved his spurting penis into hers. She devoured it, taking him deep as he bucked and squirmed from her sucking and his spurts.

"Oh fuck yeah! So good so good!" he hollered.

I had to swallow the mouthful of semen before more dribbled out, while Tami finished him off. She didn't swallow but instead kissed me, forcing the rest of his load into my mouth for me to enjoy. Once her mouth was empty she cleaned off my breasts and transferred what was there to my mouth.

Wiping her face she said, "I figured you'd want the rest, Professor."

"Mmm, yes I did. Exquisite."

The look on Mike's face as he watched us was of pure delight, "Damn that's hot!" he said, sitting on the coffee table.

His member was still rock hard but I knew it wouldn't be for long. Tami pushed me over and licked my breasts again before feasting on the plentiful juice oozing out of my vagina. I came quickly from her tongue play, convulsing on the floor while Mike watched us.

"How quickly can you get that amazing dick hard again?" I asked, looking over Tami's head.

"I'll get right on it Professor," my student replied.

"Good because I want to feel it in my body."

Tami continued to lick and devour me, moving lower to stick her hot tongue into my butt and finger my clitoris. Occasionally I would open my eyes to see the progress Mike was making on his penis. He was slowly stroking it and watching us. After about ten minutes and two more orgasms he was hard again. Another reason I love the young guys.

"I'm ready for you, Professor," he said.

"Come and get me!" I screamed.

Tami moved from between my legs, as Mike knelt on the floor. He lifted my legs and held them up and out, easing his long hard shaft into my well eaten vagina. It was phenomenal! His wide tool spread me open and filled me up like never before. I arched my back and cried out in pleasure as he bottomed out.

"Damn Professor you are really wet."

"Shut up and fuck me!" I screamed, not knowing where the language had come from.

He obeyed and proceeded to pound me so fast and furious. I ended up pushed against the sofa with my neck bent over so my chin was on my chest. He had some definite staying power now and his athletic body was in the condition to go and go. His amazing penis sent me into fits and spasms I didn't think possible. His hands were all over my body, pinching my nipples and clitoris all the while keeping up the relentless quest to shove his rod through my body.

I lost count of the orgasms he coaxed out of me by the time he was ready to ejaculate. I also lost track of what Tami was doing because of the intense pleasure and blurry vision. I just remember suddenly he wasn't in me anymore, and then semen spurted on my stomach and chest in spray after spray of hot ejaculate. My body was gone, lost in bliss and pleasure I don't remember feeling before.

Tami, licking his load off my body, brought my eyes into focus. Once she was done she fed me the plentiful supply from her mouth. I swallowed my reward and lay there completely worn out and content. I couldn't be sure but I think I heard the two of them leave my house after screwing each other one more time. I was in and out of consciousness, content to sleep on the floor naked until morning.



Biology 101 Pt. 03



I woke up sore. The sex the night before and sleeping on the floor had my body aching. The screensaver on my computer was glowing in the darkness, lending the only light in the room. I moved my finger over the mouse pad to see what time it was. 5:30, good thing I woke up or I would have been late to class. When I turned on a lamp next to the sofa I saw something that made me rather upset. I had left the samples of semen out the entire night. I was sure they would be ruined.

What a waste of delicious man juice, but I didn't want to take the chance of getting sick from them. Washing out each container I packed them back in my bag and took a shower, ate and headed to campus. It was only Tuesday. After last night it felt like it should be at least Thursday.

Tami was at her desk helping students when I arrived at my office. She grinned at me without saying anything, going back to helping the redhead girl. I unloaded all the newly empty containers and sat down at my desk to go over the lesson plan for today. I expected Tami to knock any second, when she was free, to talk about last night. Time passed and no one knocked, giving me the time I needed to prepare since I hadn't thought about class because of how excited I was for my evening with Tami, which ended up being more than I bargained for. Mike showing up was a really nice addition. I quivered just thinking about his large penis deep inside of me again.

I fired up my computer and sat behind my desk. I put a clip of Daniel's amazing ejaculations on in slow motion so I could study them further and figure out the velocity in which the semen was expelled. While that was running in a continuous loop I prepared my lesson for the day and every few minutes studied the clip. 

An hour passed by and still no knock on the door. Something wasn't adding up. Not only did I expect Tami but I expected at least one of the extra credit group to knock on my door with a sample. Especially Justin, after his ridiculous amount of samples over the weekend I figured he'd have a bunch more. 

I got up and went to my door to see what Tami was doing. Class started in a half hour but I was ready with my lecture. I cracked the door and peered out, trying to be inconspicuous. What I saw had me very worried. Everyone from the group was standing around Tami's desk. Even Sara was there and Mike. So was another girl I didn't recognize standing next to Tami, almost touching her. I had the impression that this was Jessica and that my study had just been blown.

Someone mentioned my name and Tami looked up toward my door. She caught my eye and pursed her lips to signify something was wrong. Opening the door I stepped out, making everyone turn and look at me. The looks on their faces was not good, it would appear that I was in deep shit!

"Is what they are saying true, Professor?" Sara asked first with fire in her eyes.

With everyone staring at me I gave nothing away and calmly asked, "Who are 'they' and what has been said?"

"Jessica told Justin she watched the clips he made for this 'ejaculation study' of yours with Tami. Jessica doesn't think there is any 'study' at all and that you're doing this because you get off on watching your students cum. Word got around to all of us and we were asking Tami for the truth."

My impression was correct. The woman standing next to Tami was her lover, Jessica. She must have recognized Justin's face from a clip and realized Tami wasn't telling her the truth about where she got the clips. I caught the eyes of Mike and Tami before answering. 

"Those are pretty unsubstantiated accusations, Sara. I don't know how Tami acquired these clips of Justin and showed them to Jessica, but I assure you the study is legitimate. I intend to publish my results next week if you don't believe me. I most certainly do not 'get off' by watching my students ejaculate. My study is strictly for professional and scientific research. I will be reporting my 'assistant' here for breaking into my computer, it seems, and stealing my research for her own sick pleasure."

"It's over, Emily, just come clean," Tami said glaring at me.

"I must confess Miss Richards I have no idea what you are talking about and you will call me Professor or Dr. Burke. Now I believe we all have a class to attend."

"Wait! This is bullshit. I don't believe you. You're not pinning this on me!" Tami screamed. "You don't have anything to publish, you're lying!"

"I assure you, I do and will. Now if you will excuse me," I said walking away from the group.

"This isn't over, Professor. I'm reporting you to the Dean. There is no study, you've got nothing and you know it!" Tami yelled after me.

I didn't slow or turn.

*****

A week later I published the most comprehensive study ever released on male ejaculation. After all, who better to report on the subject than an actual connoisseur like myself? I may have enjoyed my work but I wasn't stupid enough not to have a back up plan if my intentions every got out. 

Tami had no proof to the contrary and with my paper published with overwhelmingly good reception into the medical community, she had no leg to stand on. She was expelled from the university for theft and the only other person that knew the full truth was Mike. He kept his mouth shut after seeing what happened to Tami. He didn't want to blow his full ride football scholarship on a losing battle for nothing. He also didn't want to give up the hot blowjobs I continued to give him whenever he needed some 'study help' in my class.

After the confrontation outside my office I announced to the class that extra credit was no longer being offered this semester and to thank Tami when they saw her. I still gave good grades to all the participants, just not as good as they were 'shooting' for if you will forgive the pun.

I figured I'd let a few semesters go by before I started a follow up study on pre-ejaculate quantity. Just to let things settle down a bit.

*****

The last day of school arrived. It was finals and all my students were busy writing with their heads toward the test. I looked over the large room, picking out my favorite five students of the semester. Steve, Rodney, Daniel, Justin and my most favorite Mike. The last was getting an A for sure with all the 'extra help' I was giving him on almost an every other day occurrence. I got my fill of fresh semen right from the source thanks to him. This being the last day, I realized that my supply was going to end very soon.

After the last student handed in there exam I went to my office with a stack of exams to go over. Tami's desk was empty; I hadn't seen or heard from her since they kicked her out of school. Putting down all the exams I turned around when I heard a knock on the door. Opening the door I was very glad to see Mike standing there with a grin.

"I figured I'd come by for one final send off before the summer starts."

"I'm glad you did, please come in," I said letting the large boy into the room.

His broad chest brushed my breasts as he twisted to get by me. I shut and locked the door, turning to find him standing by my desk. Our eyes met and he grinned again.

"I'm going to miss you helping me with my homework."

"I will as well, it's been fun and from your grade you learned a lot," I said with a chuckle.

"Cool, well for my last lesson I thought I'd treat you to something I think you've been wanting for a while now."

"Really? And what might that be?" I asked walking toward him.

"You'll find out."

I just smiled, pressed my breasts against his body and ran my hands over the bulge in his pants. He's large member was growing already, making my mouth water. Pulling on his belt I undid the buckle and unzipped his fly, letting his pants fall to the ground. Next his boxers fell, leaving his quickly growing penis in the open for me to grab. Oh how I loved his long thick member, it hardened so quickly and was the perfect combination of soft and hard. Giving him a few strokes I fell to my knees to begin my standard oral delight to feed my fetish.

He let me suck, stroke and lick his member for ten minutes before I felt him preparing to ejaculate like normal. Instead of letting me finish him off he pulled away. He obviously had something more in mind for our last day. I was so hot and bothered I went with it and since it was the last day of school didn't anticipate any interruptions from other students.

Mike pulled me up by my shoulders until I was standing in front of him. He cupped my breasts gently, sending a chill through my body before unbuttoning my blouse. His hot hands on my flesh increased my pleasure as he removed my shirt, dropping it to the floor.

"Your breasts are amazing, professor," he said kissing the milky flesh above my bra. 

His hands worked the clasp in the back as he kissed lower. The lacy material fell off my erect nipples. He took my left in his hot mouth, sucked and used his tongue to swirl around the areola. I felt the blood pumping below in my clitoris, spurring on my vaginal secretions. Cupping both breasts in his hands he pushed them up to his ravishing mouth, feasting on my ample bosom. I ran my hands through his thick hair, enjoying the sensations coursing through my body.

Suddenly he picked me up, spun me around with little effort and laid me down on my desk. He proceeded to lick down my upper body to my stomach, while unclasping my skirt. I lifted my legs, helping him pull it off of me. I felt his teeth tugging at my wet panties while he fingered my hardened clitoris through the silky material. He quickly removed them and dove right in to devourer my womanhood. His entire mouth covered me sex with his tongue dipping deep inside my wet tunnel. The sensation arched my back spontaneously and I cried out in rapture, only to cut it off when I heard how loud I was. I needed to remember where I was and not get too carried away.

He licked, fingered, nibbled and sucked for what seemed like a long time. I wasn't complaining it was just odd he continued so long. He must really enjoy giving oral sex. The sensations grew inside of me until I was screaming from within for his monster shaft to penetrate me. I finally had to grab his head and pull him up for him to get the hint I wanted his penis. He wiped his mouth, smiled down at me and moved forward with his large erection in his hand.

"Give it to me, I want your cock inside me again!"

With no hesitation he rushed into me filling me full of his large member until his hips met mine. The sensation took my breath away, not giving me enough air to even scream in delight. Before I could catch my breath he pulled out and slammed back in even harder, rocking my breasts forward in a circular motion. By instinct I reached up and held both of them as the barrage of thrusts continued from the well endowed young man between my legs. I think I was instantly climaxing from all the built up excitement his cunnilingus had caused.    

Not only did he fill me full he spread me wide, taking me places, once again, I had scarcely been before. His penis was amazing and the young man knew how to use it. His athletic body was relentless in his thrust and power, never easing up on my quivering body. I don't remember if I screamed, moaned or what I did, I just remember being in a state of rapture rarely felt and highly coveted. It went on and on as he continued his long deep thrusts into my body.

I fully expected him to climax with the effort he was putting forth but he surprised me, continuing longer than I estimated. When he pulled out I was about to jump off the desk to receive my reward with a torrent of hot delicious semen but he stopped me with a hand on my stomach.

"Not quite yet, Professor, I haven't given you that treat I told you about."

I looked up at him perplexed, not knowing what he could possible give me more than he had.

"Ever since you watched me give it to Tami in the ass I know you've wonder how it would feel if I did it to you. Am I right?"

He was saying all of this while rubbing the head of his penis around my anal opening. It felt really good and by the way his bulbous head slid around on my body I could tell it was well lubricated from my insides.

"Well, maybe a little," I confessed.

"You're about to find out," he said pressing forward ever so slowly.

I was about to resist, worried about how big he was when I felt his head ease into my anus and stop. It was tight but not terrible. He watched my face for any sign of pain before proceeding. Pressing further, another inch of his extensive member penetrated my bowels, sending a strange sensation through my body. It was definitely different but I kind of liked it. Before he moved any further his hand began playing with my clitoris. The reaction my body experienced as he did was very surprising. The sensation was amplified with his large penis partially in my rectum. It was very stimulating, causing my muscles to involuntarily spasm on his shaft. He felt the reaction and moved forward, deeper into me.

My heart raced, my breath came in short gasps as I felt his long member continue to slide deep within my bottom. It was new, it was different, it was exciting and I was enjoying it, something I hadn't expected, especially with how big he was. More and more of him entered until I felt his body hit mine. He had all ten inches buried in me now, something I didn't think possible. He held himself inside for a time, letting me adjust to the sensation, while still playing with my clitoris.

Slowly he withdrew, causing a new sensation and pleasure, raising the level of bliss I was experiencing. He never stopped playing with my clitoris as he rushed back in, faster this time and back out. I still had my breasts in my hands, squeezing my nipples as I felt his long shaft bottom out inside my anal canal. The expression on his face was one of pure delight. He looked like he was really enjoying the sensation of my tight muscles and hot bowels around his thick shaft.

He was hard and on the verge of orgasm with only a few cycles of his penis inside my lower hole. I could tell by the rigidity of his shaft he was going to climax soon. It was a good thing too, I could feel my body cramping up on his huge shaft, it still felt good but I knew if he took too long it wouldn't last.

Another minute of thrusting and he said, "I'm going to cum," pulling his shaft free and stepping back.

Quickly I slid of my desk to my knees in front of him. Opening my mouth he lowered his head, while stroking. An enormous burst of semen shot from his slit, spraying the top of my mouth and down my throat. Luckily I wasn't inhaling at the time and was able to manage the long blast. His body shook, causing him to discharge his next contraction over my head, with part of it landing on my forehead and hair. I quickly moved up, taking his head in my mouth so I didn't miss any more. Several other spurts of semen entered my mouth from his contracting penis, filling me full of delicious thick hot ejaculate.

Swallowing quickly, before I was overwhelmed, I sucked his head, causing him to jerk and buck away from me. He was still stroking and the last few small spurts splattered onto my breasts before I could suck the rest out of him.

"Damn, Professor, that's so good, so intense when you suck it."

"Tastes so good, Mike. And so much for me this time. You must have enjoyed my ass."

"Mmm yes I did. It was amazing."

"Good, I'm pleased. I've enjoyed this semester with you, Mike. This was a nice end to a wonderful arrangement."

"Totally."

"I'm also delighted you decided to keep my secret. I hope I've made it worth it."

"Big time, I may be a dumb football player but I'm not a total idiot."

"No, you're not," I said, chuckling.

He began to find his clothing. I sat behind my desk naked, dipping my fingers in the left over semen that had landed on my breasts. I watched him dress while licking my fingers clean.

"I should go. Thanks again for everything, Professor," he said smiling.

"You're welcome, Mike. Enjoy your summer break, maybe I'll see you in the fall."

"I hope so."

He unlocked the door and walked out of my office. I sat back in my chair, caressing my breasts for any left over semen and wondering if I'd see him again. It really didn't matter, next fall I'd have another class full of new students. One of the best things about college is I get a fresh supply of kids each year and they stay the same age as the last batch.

I smiled when I found one final drip of ejaculate, raised it to my lips, savored it and smiled at the thought of next fall. 



The End
