After the weekend full of fun we'd had with Val I was kind of surprised at how sexually hungry Danielle continued to be through the beginning of the week. I did notice, though, that my lover seemed to be directing the sex we enjoyed a particular way: not once, Monday through Thursday, did she allow me vaginal intercourse. Every time I got close to sticking my length into her pussy -- which seemed to be constantly wet and ready -- she'd direct me to her backdoor or she'd stop me to tell me how bad she wanted my cum in her mouth... something. It wasn't until Thursday afternoon that I realized what had been going on. My lover was going to finally get Darrin's cock this evening in class as they demonstrated intercourse and I was sure she was "saving it up" for him.



Our Thursday was a usual work day although Danielle did end her work schedule a bit early. As I finished up mine I heard her get the shower started and knew that she'd be extra careful in her preparations for tonight's class. I tried (and failed) to concentrate on work and finally just gave up. Ending my own work day I headed up to the master bath where I found Danielle very carefully shaving her pussy lips. She'd already shaved her legs and the rest of her looked squeaky clean. Her entire demeanor made it clear that she was extremely excited about the evening and I was quite happy for her as well.



I didn't see the need to change my clothes to go to class so I got to sit and enjoy watching as Danielle carefully did her hair, applied a very little bit of make up and then searched naked through her closet for appropriate clothing to wear. I found this humorous as we both knew she'd only be wearing it long enough to get to class. Finally she picked out a calf-length skirt with a matching angora sweater. The sweater was snug enough to show off her healthy boobs but didn't LOOK blatantly slutty. The calf-length skirt was rather plain, but knowing that she had nothing on underneath it still excited me. Somehow, my lover always excited me.



We headed out to my car together and rode in silence over to the college. It was the last class of the semester and our Human Sexuality program had been more than interesting. Not only had it been one of the most instructive classes either of us had ever taken, the fact that it used live demonstrators for the sexual techniques discussed made it highly stimulating. Of course, having Danielle BE one of those live demonstrators made it even more exciting and she certainly had enjoyed showing off her exhibitionist side as she participated in various sexual activities in front of the entire classroom full of fellow students. Last class she'd given her demonstration partner, Darrin, an exceptional blow job, showcasing her deep throat talents and sucking down his load of cum. Unexpectedly we'd had another watcher -- a Dean from the college -- and that had made everyone a tad nervous. Afterward we were quite surprised to find out that Dean -- Val -- was envious of Danielle, her talents and our sexual lifestyle and she'd come home with us to explore. It was an interesting weekend (see part seven for that full story).



When we arrived at the college, before getting out of the car, Danielle grabbed and squeezed my hand. She seemed excited beyond coherent speech and I knew she was very much looking forward to what was going to happen in class. I squeezed back to offer her support and happiness. Our eyes met; we smiled. She sighed and then released my hand. Out of the car she took it once again as we walked to class.



At the classroom door I heard my lover inhale a deep breath, hold it for a second and then exhale the whole thing. I looked at her in askance; she nodded and I opened the door for her.



The classroom was as full as I'd ever seen it. Throughout the semester there'd been times when not every student could attend every class so there seemed to always be scattered empty seats. Not this evening. Every chair (except mine and Danielle's) had a student in it. I also noted Dean Valerie Johnson (Val) sitting in a chair near one side of the room. I heard Danielle's gasp of breath when she saw Val there too. I don't know why it surprised her and I'm sure it wouldn't matter in what she did or didn't do or how much she enjoyed whatever, but neither of us was expecting to see Val there so it was a mild surprise.



Professor Halbrecht greeted us warmly, shook my hand and then led Danielle away from me by one arm. He was speaking softly to her as I took my seat, met Val's eyes and nodded a silent "hello". She smiled and nodded back and I saw her twitch her hips in her seat. I immediately remembered how wonderful those hips looked naked as I fucked her hard doggy-style the weekend before and I wondered if she was remembering the same thing?



My attention was brought back to the classroom as Professor Halbrecht cleared his throat, quieting the classroom. I noted that Danielle wasn't undressing as she usually would have and wondered what was going on. "Class," said Halbrecht, "We've had a slight change of plans for this evening." A murmur of whispered curiosities rolled through the classroom and more than one set of eyes looked at Dean Johnson, wondering if she was the cause of the change of plans. Clearing his throat again, Professor Halbrecht regained a silent classroom and began to explain. "You all might not be aware but this is one of four scheduled classes on Human Sexuality that the college offers. Each is taught in the same fashion using live demonstrators and there is rarely a hitch in the curriculum." He paused before continuing. "This semester there has been a small hitch and Dean Johnson," he indicated her with a nod of his head in her direction, "has asked if we could help out. I felt fairly sure we could but needed to check with our demonstrators to be sure and just a few moments ago got my answer from our female volunteer demonstrator, Danielle." He inclined his head toward my lover who was nervously smiling as she stood to one side of his desk. It was then I realized that Darrin -- the male volunteer demonstrator -- wasn't in the room. What was going on?



Professor Halbrecht continued. "It seems that several of the demonstrators for the other classes felt unable to perform properly for this last class of the semester revolving around intercourse and so those individual classes have been left incapable of completing the full program without our assistance." He paused, breathed deep and then continued. "So, at the request of Dean Johnson, I've asked our demonstrators if they would mind expanding our student population to include those other classes and they've graciously indicated their willingness to do so. What that means is that we're not holding class here this evening. Instead, I need all of you to move down to the student auditorium where the other class bodies are waiting. There we'll complete our class in a combined setting with Danielle and Darrin serving as our demonstrators for all four classes together." He looked around to make sure everyone understood. There were no questions. "Very well," he said. "Class will recommence in five minutes in the auditorium."



There was a general noise of students grabbing books, notepads, pens, and chairs scraping as the room was vacated. Danielle walked out of the room with Professor Halbrecht before anyone else had even gotten their stuff together. I found Dean Johnson at my side as I walked toward the door and noted the pleasant excited smile on her face as we walked silently together to the auditorium.



When we got there I found a seat in the fourth row center and then it dawned on me that while Danielle had been a willing demonstrator for our class of about 30 students this semester, she was now going to be demonstrating intercourse in an auditorium that held well over 100 students. Looking around I re-evaluated my guess and figured it was closer to 120 -- about 90 more men and women who hadn't previously seen her naked. This evening they were not only going to see her naked but they were going to see her get fucked by her demo partner, Darrin, live and in person. I was distracted by, and pleased to see, Dean Johnson sitting down next to me. Since she and I and Danielle had spent most of the previous weekend in exploration of her (Val's) newly released sexuality, watching Danielle perform with Val sitting next to me would bring a new and different feel to the experience of seeing Danielle perform.



As Professor Halbrecht and his three counterparts from the other classes prepared things on the stage, I took note of the lighting and looked around at the sound booth that was at the back top center of the auditorium. Sure enough there were two students up there running video equipment and all of the lights were positioned so that Danielle wouldn't really be able to see anyone in the auditorium. Certainly, just as I had, she'd walked past them all and seen them before she got up to the stage, but she wouldn't be able to see them as she demonstrated for all of them this evening. Out of the blue I realized that my cock was rock hard and I was excited for my lover. Would I be able to get a copy of the video that I was sure was being made? Would Danielle even know? Had Professor Halbrecht mentioned it to her? So many exciting questions...



On the stage was what I guessed to be a full size bed, assembled with the most minimal of metal frames. The mattress was on top of a set of box springs and a plain white sheet covered it. A podium was set to one side and there were four chairs behind the bed, almost all the way to the back of the stage. Four more chairs were arranged to the right side of the podium (as I looked at it) and I realized they were most likely for the four professors teaching the course.



Knowing there were four chairs for four professors made sense. But why were there four chairs back behind the bed? I assumed they were for the demonstrators but there was only Danielle and Darrin, right? As I looked around the stage I realized that Halbrecht had Danielle off to the left side, just visible behind some of the stage curtains. They were chatting with Darrin and two other men I didn't recognize. Every one of them had a serious look on their face but beneath the serious expression lurked a simmering level of excitement and anticipation. I noticed that Danielle seemed to be dancing back and forth from one foot to the other as she listened to Halbrecht, shook hands with the other guys and hugged Darrin. When the conversation appeared to be over, Halbrecht stepped out from behind the curtain and headed over toward the podium. Danielle and her three male compatriots stepped in the other direction so that they'd be completely out of sight of anyone in the audience. As Danielle was almost out of my view I saw her pulling her sweater off over her head. My last glance of her was her bare back and her ass swishing in her skirt as she followed her three male friends back into the darkness behind the curtains.



I looked at Val with a questioning look in my eyes and realized that she looked as surprised as I was. My attention was diverted back to the stage at the sound of Professor Halbrecht clearing his throat at the podium. The students who had been milling around chatting all got quiet and found a seat. The other professors had joined Halbrecht on stage and were all sitting in their chairs off to the right side of the podium (as I looked at the stage).



"Good evening," said Professor Halbrecht. "Welcome to this semester's final class on Human Sexuality." He gave it a moment and let the quiet sink in to the audience. "This evening we faced somewhat of a challenge as some of the demonstrators decided not to attend this final class. That left us in a quandary about how to best insure every student received the remainder of the instructional curriculum. As things have worked out, at the suggestion of Dean Johnson and with the agreement of my fellow professors, we've combined all of the classes into this one and will be using a combination of demonstrators so that you all can finish up the program."



A combination of demonstrators I wondered to myself? Was Danielle going to have to perform with more than just Darrin? Who was I kidding? She was going to HAVE to... she probably wanted to and, if I knew her, she was aching with desire to enjoy all three men she'd been talking to in front of the auditorium full of students. It would be a climactic ending to the fulfillment of her fantasy of performing as a sexual demonstrator in front of so many people. Professor Halbrecht continued.



"This evening we'll be reviewing all of the previously covered foreplay sexual activities as well as then discussing and demonstrating vaginal intercourse in a variety of positions, each offering its own benefit or particular type of stimulation." He paused, found Dean Johnson next to me in the audience, got a slight nod from her, and then continued. "Additionally, as an added bit of instruction, we may -- depending on the willingness of the demonstrators -- be able to introduce and discuss sexual activity involving more than two partners, typically referred to as multiple-partner-sex or group sex." A rumble of hushed comments rolled through the audience and Professor Halbrecht had to hold up his hands to quiet the students back down before continuing. "Our female demonstrator, Danielle, has voiced her willingness to demonstrate such and her male partners -- two of whom she just met a few minutes ago -- have also voiced their willingness. Time will be the determining factor."



As he finished that sentence the lighting in the auditorium changed. The lights over the audience were lowered almost to the point of being totally dark while the lights on stage were adjusted so that the brightest point was the bed. As Halbrecht began to speak again, Danielle and Darrin walked onto the stage from the left -- opposite the side the professors were sitting on -- both completely naked, each with an arm around the others waist. I noticed that Darrin wasn't his usual level of erect and wondered if performing in front of such a large audience was making him nervous. As they walked toward the bed, Halbrecht continued.



"Our demonstration couple is going to quickly review the components of our previous classes to include self- and mutual-masturbation, oral sex and then they'll move into intercourse." As he talked, Danielle and Darrin got onto the bed, each of them laying down so that they were facing the auditorium, Darrin at one end, Danielle at the other. I was close enough that I could clearly see how wet Danielle's pussy was when she lay back and spread her legs. Her nipples were stiff and I could see the heat of her excitement in her eyes. Darrin looked like he was stiffening up some more and I knew that even if he had trouble, Danielle would have no trouble at all getting him fully erect. She'd have to so that she could get what she most wanted that moment: Darrin's hard long shaft buried completely into her sweet shaven deliciously wet sex.



"Quite often," Halbrecht talked as Darrin and Danielle began to touch themselves, "masturbation only occurs when a man or woman can't find a suitable partner to achieve sexual release. Interestingly, self-masturbation by lovers before an encounter can serve to stimulate both. Not only is the person masturbating receiving efficient pleasure because they know themselves so well, but usually they are stimulating the imagination and desires of the partner who is watching while they also masturbate." As he spoke Darrin had been stroking his steadily harder length while Danielle had first rubbed her finger up her slit and across her clit before sinking two fingers into her wetness.



"There comes a point, however," said Halbrecht, "when desire overwhelms the human system and more contact and stimulation is required." Once again, as he spoke, Darrin and Danielle moved, this time closer together, their lips meeting for a kiss as their hands reached for each other. Danielle's hand grasped and took over the stroking of Darrin's now fully erect cock, while his hand found its way between her spread thighs and he wasted no time replacing her two fingers with his own, plunging them as far as he could reach into her sex. The mutual moan that escaped them rolled across the silent audience with the effect of a tidal wave. Suddenly plenty of the students were having trouble sitting still. Male students were adjusting themselves, seeking comfort as their growing erections were confined in their pants. More than one female student slumped in her seat, slightly spreading her thighs and allowing for the release of the building pressure in her sex.



"As good as mutual masturbation feels, however," continued Halbrecht, "oral stimulation feels nearly as good as -- and some people think better than -- actual intercourse." Once again Darrin and Danielle were moving. Darrin turned and laid down so that he was sideways to the audience. As I watched, Danielle straddled his head and lowered her face to his waving shaft. It didn't wave long as her mouth engulfed it without hesitation. He moaned in pleasure at the same moment Danielle lowered her pussy onto his face. I saw his tongue stuck out before I lost sight of it beneath her. After a moment I realized that Halbrecht was still talking. "... tongue and fingers are insufficient to achieve the necessary depth of penetration of the vagina to bring full sexual satisfaction. However, a talented woman, as Danielle is, can relax her throat and provide a full-length stimulation to the penis, commonly called 'deep throating' and providing for full sexual satisfaction to the male." As he was talking Danielle was indeed deep-throating Darrin's cock, just as she had previously in our class.



I heard Val moan next to me, and looking over saw that she had adjusted her position in the seat. Although it was pretty dark I could see that she had her skirt pulled up enough to get her hand beneath it and her hand was indeed beneath her skirt, moving steadily. A glance at her face showed a glazed look of sensual excitement. Slowly, so as not to draw any attention, I reached my hand over to her thigh and every so gently touched her. She jumped slightly, looked over, saw the look in my eyes, and then spread her thighs farther, pulling her own hand out of her crotch. I replaced it with my own, finding her not wearing underwear and her pussy smoothly shaved. She was dripping wet and her clit was erect. As the action on stage continued I slowly pushed two fingers into her moistness, dragging them up and over her clit with every stroke before plunging them back into her. She slumped a bit more in her seat and pushed her thighs even farther apart.



As I continued finger-fucking Val, Halbrecht continued his lecture with Darrin and Danielle moving as he talked. "Our demonstrators have now demonstrated all facets of sexual stimulation previously covered in our classroom presentations. At this time I'm going to ask them to move into what is commonly called 'the missionary position' and begin demonstrating vaginal intercourse."



Disengaging themselves from the 69 position, I watched Darrin stand up off the bed out of the way for Danielle to lay down on her back, side on to the audience, and spread her legs wide to make room for Darrin. Having enjoyed her so much, and knowing her body language so well, it was obvious to me that she was seriously craving having his cock inside her...



When she was in place I watched as Darrin climbed between my lover's legs, supporting his weight on his knees and his hands and let Danielle do the honor of directing him. As she reached down to guide his cock to her wet opening, Halbrecht narrated. "In many first time intercourse situations, the woman wishes to be on top so that she can control how deep and how fast initial penetrations occur. Such a position also allows her to control her own stimulation, using the male phallus if you will, for her own pleasure."

<hr pg="2" />His words were lost somewhat in the background of my mind as I watched Darrin, in front of about 130 people (students and instructors all totaled), begin to sink his cock into my lover's hungry cunt. Danielle's eyes were locked on Darrin's and she had once told me that she felt this was the most erotic moment of all: seeing the look on a new lover's face as first penetration was achieved. She described in some clear detail how it felt to have a new, previously totally strange, cock sliding between her inner lips; stretching them open; pushing into her canal and stretching that open as well... deeper and deeper until their pelvises were grinding together and full penetration had been achieved.



"In this case," Halbrecht was saying, "for the purposes of demonstration, we've chosen to start with the missionary position. Note that a significant part of the act is not just the movement of repeated penetration and withdrawal but also the time spent forcing the genitals together, insuring a complete union. This is an instinctive and natural action which helps the weaker swimming male sperm cells reach the uterus for impregnation."



Darrin had obviously gotten all of his length into my lover's succulent sex and it pleased me to watch her head fall back, her back arch up and her legs spread even farther as they ground together. As much for demonstration purposes as this act might be, she was totally reveling in the pleasure of his length stretching her open and filling her up. I heard Val moan beside me and felt her hands clamp down on my forearm as my stirring fingers brought her to climax. I'm glad she could keep things quiet -- otherwise the nearby students might have realized that the Dean was having an orgasm in their midst.



Halbrecht's lecture got lost in the fuzz of excitement for me as I watched Darrin plunge his length in and out of my lover, Danielle. I continued to finger Val through a series of orgasms as, under Halbrecht's directions, the "demonstrators" changed their positions around. I could almost feel the whole audience of students squirming with discomfort and excitement (except for Val who was squirming through orgasms) as Danielle and Darrin shifted positions every few minutes or so:



They had started in missionary and then moved so that Danielle was on top, facing him. First she was laying down against him riding slowly and getting plenty of pelvic rub. Then she was sitting up on him, her hands braced on his chest, his hands on her hips, both of them working hard at rubbing her back and forth on his cock. She achieved her first orgasm in that fashion before getting off of him so that he could adjust his position. So far they'd been side-on to the audience, but he moved so that his feet were facing us and she restraddled him, reverse cowgirl fashion.



I had a clear view of her slightly swollen, bright pink and dripping wet lips as she lowered herself onto his length. From head to balls in a single downward motion where, once achieved, she rotated her hips around, stirring his cockhead against her cervix and closing her eyes in the pleasure of him being so deep. Leaning forward slightly she rested her hands on Darrin's knees and began to ride / grind until she reached another climax. Idly I thought it was nice of Halbrecht not to ask her to move into a different position until she had...



From there they moved into doggy style -- side on to the audience again -- before switching to standing with Danielle bent over the bed, and then to her laying on her belly, hips arched up to accept his plunging. Throughout it all Danielle looked to be enjoying an orgasm in each position and Darrin soon looked like he was having a hard time holding off on his.



Having demonstrated all the positions that were apparently included in the course curriculum, Danielle and Darrin were given 'demonstrator discretion' to choose what position they'd like to 'finish up in' as Halbrecht put it. A few quiet words passed between them before they separated and Danielle once again laid down on her back. As Darrin climbed between her thighs this time though, he hooked her knees up over his arms so that her thighs were forced back high and wide as he slid his length into her.



I felt Val clutching my arm again as Darrin aggressively pounded Danielle's body into the bed, working against the spring action; forcing his length in and down as the springs were bouncing her body back up. Steady moans and keening sounds were escaping Danielle as Darrin closed his eyes and focused on getting his orgasm. The speed of his strokes sped up and then again until finally -- in front of that room full of people -- he threw his head back and almost howled as he came, his cock forced as deep into Danielle's welcoming sex as he could reach. We all watched in silence as Darrin's body twitched and jerked through his climax and my own cock jumped as I thought about his length jetting thick sticky ropes of hot cum so deeply into my lovers quim.



When his orgasm finally passed, he collapsed on top of my lover who wrapped her arms and legs around him and held him close, both of them reveling in the warmth of the completed union. Halbrecht said a few words of thanks to the Dean, singling her out in the crowd as she caught her breath from her latest climax, his fellow instructors and the demonstrators, which he gestured at and who completely ignored him as they were still catching their breath.



Then Halbrecht looked at his watch and said, "But we have about ten minutes of class time left. If any of you would like to stay you can; if you want to leave that's approved as well. The course curriculum has been fully covered." He paused for several minutes as about half the students gathered their belongings and left, no doubt eager to get someplace semi-private to seek relief from the frustrations created by what they'd just witnessed.



After the room had cleared of those leaving Halbrecht continued. "For those of us remaining, we're going to get a special extra education. Danielle has generously agreed to act as female demonstrator with two male demonstrators so that we can discuss, however briefly, multiple partner sexual play."



Upon hearing those words, Darrin extricated himself from Danielle's embrace, his slack length dripping their mixed juices as he moved up and off of her. For her part, Danielle didn't even move, simply laying their spread, on an angle to the audience, her pussy looking thoroughly well fucked. Darrin's cum was easily seen flowing slowly out of her love channel and I could see her chest still heaving from the pleasures she'd just received.



After a few minutes of rest, as Halbrecht continued to lecture about various combinations that are available and the on-going consideration of bi-sexuality when you have more than one partner of the same sex in any sexual encounter, Danielle used a towel from her chair to wipe up a bit (Darrin's cum was still running out of her combined with her own juices) and then laid back down on the bed. The other two men I'd seen her talking with walked out onto the stage from the left side, both of them naked; both of them sporting pretty good size erections. One was white, about six foot, and built well with little body hair. He looked in his late twenties. The other was a very dark skinned black man, about the same height and build with even less body hair. Both looked to have cocks a bit bigger than average, but certainly nothing worthy of a porn movie and nothing Danielle couldn't handle with some semblance of ease.



As they approached the bed, Halbrecht concluded his lecture and invited everyone to get a closer seat down in front since many of the other students had left. He assured us all that the auditorium was reserved for our use for another hour although class would officially end in a just a few minutes. Students began to move around to get closer seats just as the two men took up places on the bed on either side of Danielle.



It was then that I noticed, thanks to everyone repositioning themselves in the auditorium, Val and I were seated a row behind the nearest students and there was no one seated behind us. Thanks to that circumstance I didn't object when I felt Val reach over and start to unzip my pants, unbuckling my belt, unbuttoning my pants and helping me squirm them down a bit to free my aching erection. As her hand began to gently stroke my length the two men on the bed with Danielle began to caress her body.



Danielle seemed to come alive at their touch, putting her arms out so that she reached around either one, seeming to pull them in closer. Both men bent to kiss her at the same time but the black man adjusted so that his mouth met one of her nipples instead. She kissed the white guy for a few minutes, moaning through the sucking and nibbling on her tit, and then the men switched. The white guy took on her other nipple while she tongue-wrestled with the black guy. A sharp gasp from her that interrupted the kiss caught me by surprise until I realized that BOTH men had a hand between her legs. How many fingers, of what color, I wondered, were inside my lover's wet sex? Whatever the answer, she was obviously enjoying it.



As Danielle's two new lovers took turns at her chest and mouth, their hands steadily working between her now wide spread thighs, Val began to use my freely flowing precum as lubricant to speed up her strokes of my cock. With a very soft groan I turned to her and whispered, "You should just have a seat on it so we can both enjoy ourselves." I expected her to balk at the possibility of getting caught -- a dean riding a student in a Human Sexuality class would hardly be acceptable -- but she didn't hesitate for two seconds. I saw Halbrecht notice the movement as Val stood up a bit, moved her hips over to mine, pulled her skirt up out of the way (and I was nice enough to hold it up around her waist) and then straddle my lap with her back to me. As she sat down slowly I guided my cock to her pussy entrance and she settled peacefully onto me, taking my length in a single penetrating stroke.



Her pussy was deliciously wet, hot and silky feeling as she ground down onto me. We had to keep our movement to a minimum so as not to draw notice, but I still saw Halbrecht look at us from time to time as Val ever so slowly ground around and then rode up and down on my aching length.



On the bed the men had moved around so that the white guy was between Danielle's legs, preparing to penetrate her, as the black man moved to kneel by her head. Just as she turned her head and opened her mouth to accept his stiff black cock, the white guy slid his length into her. The resulting moan from Danielle vibrated all around the black guy's cock causing him to moan as well -- and the white guy added a moan simply from the pleasure of having his shaft encased in Danielle's velvety warm wetness. Both men began to pump slowly at my lover, both between a set of lips.



Danielle had another orgasm as her two men plunged their lengths in and out of her at either end, and when she came down I saw her pop the black cock out of her mouth and I heard her say something but I couldn't quite make it out. I was more than a little distracted by the feeling of Val's sex milking and caressing my length and I could feel her pussy juice flowing out of her and down across my balls -- which surely felt full and in need of emptying.



In a mischievous moment of naught pleasure, I reached a hand around Val to put my fingers on her clit, rubbing to add to her delight and wondering if she'd be able to control herself enough to stay quiet. As I did so, the guys on the bed switched positions. The black guy mounted Danielle while the white guy fed her his length which was covered with her pussy juice and, I'm sure, some of Darrin's remaining cum. The black guy was much more aggressive in his fucking and pounded her at a fast rate, not seeming to care if that stopped her from being able to focus on the white cock in her mouth or not.



The pounding worked though as Danielle enjoyed two more orgasms as a result before pushing both of the men away. Again she said something I couldn't really understand and as they began to move around on the bed I felt Val's pussy grasp my length like a vice as she came. I was impressed at her self-control as she managed not to make a sound but I could feel her entire body tremble on top of mine as she squirmed in quick jerky movements, every one of them seeming to push her harder onto my length, stirring my cockhead against her cervix. It almost made me cum... why I didn't, I don't know to this day.



On the bed the black guy was on his back and Danielle was just straddling him. The white guy was standing next to the bed, idly stroking his shiny length. What was going on I wondered? Whatever it was, it was what Danielle had asked for. It excited me to see my lover so unashamedly straddle the black cock standing erect for her, sliding her pussy down onto it and grinding down just as Val was on me. She humped up and down the length for a few moments and then settled onto it fully, stopping and nodding at the white guy. My excitement grew as I watched the white guy get on the bed behind her, settling down on his knees and presenting his erection to her puckered back door.



Now Danielle is no stranger to anal sex, but double penetration? It wasn't something I thought she was familiar with. In fact, it wasn't something I was SURE she'd experienced before. What I knew now was that she was definitely going to experience it right then; with two almost total strangers; on a brightly lit stage; being video-taped; in an auditorium; in front of about 80 adults, four of whom were college professors and one of whom was a Dean. Of course, the Dean was, at that moment, doing her best to get me to cum into her, but that thought didn't really cross my mind. My lover was being so entirely sexual I was excited beyond words...



As Val continued her grinding the men settled into a rhythm, fucking Danielle between them. Her pussy and ass were being filled, emptied and refilled at a steady pace that was speeding up ever so slightly as they went. Within a few minutes Danielle was moaning and groaning constantly and appeared to be having a never-ending orgasm. The white guy, quickly pumping into her tight ass, came first. As he did so, and quite obviously, I was overwhelmed and began to cum myself, launching my thick ropey strings of jism up into Val's accepting pussy. She felt me cumming and ground down harder on my length, insuring that I came as deeply into her as I could physically reach. As I was coming down off my orgasmic peak, the black guy also came, burying his length up into my lover on the bed on stage and pushing her over the brink one final time as well.



I almost felt like I'd participated in the sexual acts on stage as I sat trying to catch my breath, recovering from my own climax and feeling Val work her love muscles around my length as if trying to milk more out of me. On the stage, Danielle was collapsed against the black guy, the white guy nearly equally collapsed over her back. They all looked quite pleasured and exhausted. I was unable to focus on what Halbrecht said, but realized whatever it was it had motivated the students to gather their belongings and start to head out. Before any of them could turn to see her straddling me, Val nearly lunged off my lap, moving fast enough that by the time my sperm began to run out of her fucked-open lips it was landing in globs on the auditorium floor and not my pants or legs.



I managed to get my pants up and relatively looking like nothing was amiss as Val sat serenely with her skirt pulled down over her thighs, hiding what I was sure was a pretty well used looking sex that was still flowing my cum and her juices. Up on stage Halbrecht caught my eye and gestured me to come up. Thankfully he turned away once he realized I'd seen him so when I stood up no one was watching me button, zip and buckle.



By the time I'd reached the stage the white guy had gotten out / off of Danielle and she'd climbed off the black guy. The black guy, for his part, hadn't moved and all of the cum that had run out of Danielle was smeared and coagulating on his balls. It was a sight I'd never seen before -- not even in porn movies and my first thought was, "He'd better clean that off before it dries or it's going to hurt."



Danielle was sitting on the edge of the bed still recovering her breath and strength when I reached her. I got another towel from the chair and offered it to her. She took it with a tired looking smile and began to wipe the smears of cum off of her thighs and from her crotch -- both front and back. As she was doing so Halbrecht came over with a big smile on his face. He'd seen Danielle naked in virtually every class so she had nothing to hide, but it still seemed odd to have him standing there, less than two feet away as she wiped the cum of three men off her pussy and from between the cheeks of her ass.



Through his smile Halbrecht said, "I'd really like to thank the two of you for all your help this semester."



I interrupted. "The two of us?" I asked. "I didn't do anything but attend class."



"Yes," acknowledged Halbrecht, "but Danielle told me early on that she wouldn't be a demonstrator unless she was confident you wouldn't have any problem with it. Obviously you were supportive of her willingness to perform for the class and it really was of great assistance. I don't think we'd have found another willing student, and this evening," he said, gesturing around at the auditorium and the other instructors, "makes it all too clear how hard it is to find women willing to be demonstrators in so complete a fashion."



With a happy content look on her face and a slight grin to accompany it Danielle said, "I'd volunteer every semester but I'm not sure I could keep up with all these young men on a regular basis." She chuckled at the thought and Halbrecht followed suit. For my part I wondered if my lover wasn't under-rating herself. I was sure she could keep many young men happy and worn out; keeping up wouldn't be a problem, but it seemed an inopportune thing to say at that moment.



"Well, if you ever want to volunteer again..." Halbrecht let the words trail off.



"I'll email you if that happens," said Danielle, looking over at me with a smile. What did she have in mind? More importantly, I had something else on MY mind.



Turning to Halbrecht I gestured up at the sound / projection booth. "Was this whole class recorded?" I asked.



"Yes, it was," he replied. "Danielle and I discussed it on the way to the auditorium from the classroom and she agreed to it." He felt the need to explain more as he continued. "Given how hard it can be to find proper demonstrators, I was hoping we could keep the tape for future use when we can't get a suitable pair for live demonstrations."



"Oh," I said somewhat startled. It had never occurred to me that they were making an educational video. But that didn't stop me either. It just changed how I asked the question. "Well, can we get a copy to make sure our studies stay up to date?"



With a huge grin Halbrecht replied, "Of course you can." Then he looked down at Danielle, still naked, smiling and happy and he continued, "But I don't somehow think you need help maintaining your studies in human sexuality."



With that he strode off, leaving my lover and I alone on the stage. I could see Val waiting up by one of the exit doors and wondered why. Focusing on Danielle I asked if she needed me to help her with anything. She said it would be nice if I'd help her get her skirt and sweater back on and then maybe help her to the car. She commented that her hips and legs felt a bit wobbly and it probably had something to do with the thorough -- but really enjoyable -- fucking she'd gotten from three young men in such a compressed time frame.

<hr pg="3" />After she was dressed, Val actually helped me get her to the car and then climbed in with us. Turning to look at her I asked, "Is there something you want to tell me?" It was obvious I didn't have a clue what was going on.



With a grin she said, "It's something Danielle and I worked out. She anticipated you being horny more than one cum in the auditorium would satisfy so she asked me to come home with you guys tonight to make myself available to you tonight and tomorrow for any needs you might have." She paused, smiled big and said, "or until such time as she's not too sore to fuck some more."



Danielle was almost asleep in the passenger seat as I looked at her, but there was a happy smile on her face as our eyes met. "Thank you," I said softly.



"You're welcome," she replied. "Thank you."



"You're welcome, too," I said as I started the car. The trip home didn't take long and together Val and I got Danielle into bed where she fell asleep pretty quick, still naked and still flowing cum from three men. I'd have to help her shower in the morning but Val said she'd help with that too. With Danielle sleeping satisfied and peaceful, Val and I headed out to the hot tub. This time she stripped with no hesitation, grabbed a drink and settled in, her eyes on my cock as I did the same.



It was the beginning of a long and glorious friendship between the three of us. Eventually Val retired from the college position she'd held for years, and started attending Human Sexuality classes, often serving as the class demonstrator. Danielle coached her in her cock-sucking skills and yes, I was often blessed with being the guy they practiced on. Just like Danielle, Val eventually learned to love anal sex along with regular intercourse, and with us helping her and insuring her safety, she enjoyed several threesomes with two guys and a more than we can count with Danielle and I. But it all started with that first semester of human sexuality class...
