I had told him I'd be gone all evening, on a girl's night out with my best friend Sharon, but she cancelled on me thirty minutes after I left the house. She had cited "marital obligations," which I knew meant hot steamy sex with her husband, who still surprised her regularly after ten years of marriage. Sometimes he would take off early on a Friday, and they'd spend all weekend together at a spa or resort, and fuck each others' brains out. The next week I'd have to listen to her go on and on about how fantastic the experience had been, while I sat there thinking of my Dylan, John's father, who died during a tour in Iraq, when John was still eight years old. I didn't begrudge her the fun, I'd most likely do the same if I were in her position, but that didn't mean I had to enjoy listening to it. All dolled up for nothing, and feeling frustrated, I turned around, thinking I could at least enjoy a nice relaxing evening curling up in bed with a glass of wine, watch a sappy flick, and maybe some battery powered joy. It wasn't an unusual activity these days, being a single mom had left me precious few dating opportunities over the years. I didn't want to bring a bunch of guys into John's life, so I contented myself with a few one night stands and casual flings. Lately I've been missing my husband more and more, but with John graduating high school this year, and going off to college, I was greatly looking forward to re-entering the dating world with a few good years left. Pulling into the driveway I noticed the lights in my bedroom were on, but I was pretty sure I turned them off when I left, and John was supposed to spend the evening at his girlfriend Crystal's house. I disliked that girl from the moment I met her. Maybe it was the fact that it was John's first serious girlfriend, and it felt a little like she was stealing my own son away from me, maybe it was the fact that she was actually named "Crystal" and really lived up to the stereotype that comes along with it. She always walked around in skimpy clothing, and shamelessly slobbered all over John at every opportunity. But she seemed to make John happy for reasons I couldn't fathom, and so I had always tolerated her. The things we do for our children. So, imagine my shock when I came home and heard her very voice from the direction of my bedroom. Without hesitation I swung open the door, ready to lay into her for being in my private space. However, at the sight of Crystal, eyes closed, one hand on her tits pinching her nipple, gyrating naked in pleasure on top of John, I completely lost my temper. "What the FUCK are you doing my room?" Crystal's eyes shot open, and she jumped. Hard. "You trashy whore what the fuck are you doing to my son, get the fuck out of here before I call the cops." She scrambled herself up, and with a sort of wet squelch dislodged from John. I couldn't help but stare at the rock hard cock that slid out of her. Still slick from the activities it popped out of her, and it was hard to believe just how massive it was. It had been years since I saw John naked, but he had clearly won the puberty lottery. Crystal frantically scampered around the room, collecting her clothes, and trying to cover herself at the same time. John grabbed a pillow, and pressed it on top of his cock, barely managing to cover that beast. "Mom! What the hell?" "Don't you 'what-the-hell' me, this is MY house, MY bedroom," I bellowed. I wanted to add "my pillow," but he seemed embarrassed enough already. "And you!" I rounded my fury back on Crystal, advancing towards her. "What the fuck are you still doing here?" She bolted out of the room, still naked, clutching the few scraps of fabric she called clothing. Moments later the front door slammed, apparently frightened so much she actually ran out of the house as bare as the day she was born. I would have laughed if it wasn't for my son still lying in my bed. She lived only a few houses down from us, so I wasn't too worried about her. "Mom, please!" "Get dressed. Now. You have a lot to explain." I turned on my heel, and walked out, slamming the door behind me. I took a few deep breaths to try and calm myself down. I had no idea why I overreacted this much, after all it's only natural for teenagers to do these kinds of thing, isn't it? I thought back to my own childhood, and I had lost my own virginity when I was sixteen, two years younger than John is now. It had been a dumb mistake at a party. So why was I so upset? John emerged, fully clothed, thank god, with a downcast head, looking very uncomfortable. "Mom," he started, not looking at me, "I'm sorry. We were just fooling around... she said... it was her idea. She begged me to do it on your bed." Bitch. I felt my anger flare up again at that, but for the sake of my son I tried my best to remain level headed and begrudgingly said, "I think I may have overreacted a bit." "Gee Mom, you think?" "Don't give me that sass. You had no right to do that in my room! You know that's my personal space." "I know, Mom, I'm sorry." I took a few more deep breaths, while John stood there looking dejected. I hated seeing him like this, and I was more angry at Crystal than him, really. "Well, what's done is done." As if that made things better. "I'm sorry I blew up like that, it's just... you know she gets under my skin." "I know, Mom." "Was that..." I hesitated, and wished more than ever his father were still with us. "Was that your... uh, first?" "No, Mom. I mean yes, she was my first," he stammered. "But not uh, not today?" I sighed inwardly, wondering how long she had been defiling him. The next part would be even more awkward, but I steeled myself. "John, just now when you were in her, uh... I mean in there. In the room. With her. I didn't mean to do it, but I noticed your, ah... thing. You weren't wearing a condom." He flushed a bright scarlet. "Mom!" "Oh grow up, I've seen you naked plenty of times when you were younger. Anyway, what I meant to say was, are you practicing safe sex?" The last thing I wanted was a pregnant whore of a daughter. John could do so much better than her, and I wanted him to go to college, and get a good education, not be tied down in this small town with a kid, while still in high school. He looked at me, confused. "Safe? What do you mean? Is it dangerous?" Oh boy. "Well, it's not exactly dangerous. Well, it can be. But in other ways. Oh I wish Dylan could be here to explain all this to you." "I miss him too." "What I mean is that sex can lead to... things. Is Crystal on the pill?" I inquired. "The pill? What's that?" I took that as a no. "It means she can't get pregnant. Didn't they ever teach this in school? You should have had sex ed by now." "No, they cancelled that." "What? That can't be right." An idea formed in my head. "I'll tell you what, I'm gonna call your school tomorrow, and ask if they offer any sex ed classes. Then they can teach you about all this. Less embarrassing for both of us." "Okay!" He was clearly eager to stop talking about this to agree so quickly. "I'm not mad at you, you know. I was just... surprised. That's all." "Yeah... me too." "I'm gonna watch a movie or something, do you want to join?" "No, I think I'd like to be alone for a bit. Maybe call Crys." "Fine, whatever." He went into his room, and I didn't see him again for the rest of the night. I finally poured myself that glass of wine I now desperately longed for, and attempted to distract myself from the situation by watching a movie, the title of which slipped my mind immediately. In my head I kept replaying the earlier events. I hoped I could forget how Crystal looked, impaled on my son, writhing in pleasure. She had an amazing body, the way you do when you're still young. A pang of jealousy hit me. Sharon and I exercised together twice a week, but aging has an irreversible effect on your body, and self esteem, that no amount of working out will cure. My breasts were bigger than Crystal's, so at least there's that. My mind kept being drawn back to the moment when Crystal hoisted herself off of John, his cock slowly emerging. It seemed to take much longer in my head than it actually did, and I started to feel a familiar longing between my own legs. Guiltily, I pushed away the thoughts of my son, that wasn't the right thing for a mother to do. Instead, I redirected my thoughts to Dylan, and wondered what he'd do in this situation. One glass turned into two, two turned into three. Before long the entire bottle was empty, and I spent the remainder of the evening frustrated and horny. Vibrators are great and all, but they're no true substitute for a man. I drunkenly stumbled to bed, and flopped down. My head landed on a pillow, and I was immediately aware of the fact that it was slightly wet, and that it smelled of sex. Fuck, that had been the pillow John used to cover his dick. Nobody had actually cleaned up here. I flung the pillow against the wall, but I was too drunk and tired to care anymore, and fell asleep. *** The next morning I woke up with a splitting headache. I stumbled out of bed, into the kitchen, and made myself some coffee. Ten minutes later, and the memories of last night came rushing back to me. John had already left for school, I was proud of how diligent he was about attending, and trusted him to get to school on time on his own. That left me with basically only one thing on the agenda. I dug up the contact sheet for Beaumont, and dialed. "Beaumont High, this is Sofia speaking." "Hello Sofia, it's Monica." The school was small, and I had attended enough PTA meetings that I knew Sofia Hernandez, the receptionist. Well, that was her title anyway, but she knew the school inside and out, and was the go-to person for every parent. "Oh, hey, Monica! What do you need?" "I just had a few questions about the curriculum. I was talking to John last night, and he said you guys don't have sex ed classes, is that right?" "Yeah, we removed them from required course list a few years back. Had too many parents call in and complain, something about teaching filth, and such." "But you still offer them?" "Oh, yeah we do," her voice chirped up. "It's an elective now." "And they'll teach him about, you know. Condoms, and such. Safe sex." Sofia paused for a bit, then replied, "Well, not exactly. It's an abstinence only course. State mandate." Oh, that was no good. He was clearly past that stage. "But we do have an extracurricular advanced sex ed program for kids that are over eighteen." That wouldn't be a problem at all. "Why is it over eighteen?" "I don't know the details, but the description in the student handbook says it's a course aimed at couples. You can bring your boyfriend, or girlfriend, and they'll teach you about the reproductive system, and condoms, and all that jazz. I assume you need to be eighteen because the state mandates only abstinence education for minors." That sounded perfect, I could send both John and Crystal there. I'd have to clear it with her parents, but that shouldn't be a big problem. "That sounds great, Sofia. Can you sign up my son and his girlfriend for that?" "Sure. Who's his girlfriend?" "Crystal Mason." "Ah, have you cleared this with her parents?" "Not yet, but I'm planning on it. Can you just sign them up, and I'll let you know if she won't attend?" "Sure! And which date?" "What do you mean?" "It's not an actual class, more of a seminar. We have one per quarter, the next one's this Saturday, and after that there won't be another one for 3 months. Looks like there's only room for one more pair in that." That was cutting it close, it was already Thursday. I'd have to make some quick arrangements with Crystal's parents to get them to agree before then. And, of course, convince Crystal herself, which would undoubtedly be more difficult. There was no way I would want another 3 months of unsafe hanky-panky though. "That sounds great, actually. I'll square it away with Crystal and her parents." "One more thing, since it's a special seminar there's a small fee. It's five hundred dollars." I inhaled sharply. I had the money, since I just got paid this week, but five hundred bucks was still pretty steep. "That seems like a lot of money for a seminar." "It says here the money is used to pay for the material, condoms and such, I guess. The whole thing is arranged by a Dr. Sorensen, she's a sex therapist out of New York. Must be famous, or something." "Hm... five hundred is still a lot less than a baby costs. I suppose it's worth it." "Oh, and it's non refundable. Well, it is if you cancel it with a three days notice, but since it's tomorrow that doesn't really apply to you." "Fine, whatever. I'll bring the money by later today." I'd just have to be extra convincing to get them to go. "Sure thing, Monica. It's this Saturday at eight in the evening, room 305." I jotted it down. "Thank you so much, Sofia. I gotta get going now. I'll call if anything changes." "Have a great day!" "Thanks, you too." I hung up, mentally checking off one thing on my todo list, but having to add a few more. After a quick shower I tossed the sheets in the laundry, and put on my uniform. Nothing special, just a simple white blouse and black slacks. I worked as a waitress at a small family owned restaurant downtown. It wasn't much, but combined with Dylan's army death benefits it afforded us a decent life. Certainly not glamorous, but we never had to worry about making rent, or going hungry. I even managed to squirrel away a sizeable chunk for John's college fund. During my lunch break, I swung around by the school, and paid the fee, in cash. *** I normally get off work after school is already over, so I typically bring something off the restaurant's takeout menu home with me. Today, I selected spaghetti with meatballs, John's favorite, hoping to appease him with good food, while delivering potentially unpleasant news. He was already waiting in the kitchen, looking a bit somber. Normally he has the healthy appetite befitting a growing adult, but today he just picked at his food, not really eating anything. Hopefully he wasn't too upset with me from last night. I studied his face while I ate, noticing just how much he'd grown up over the years. It really sneaks up on you, the changes are so gradual you don't really notice them, until it suddenly hits you. He had some of Dylan's features, especially his eyes, but they were just a touch softer. His dark brown hair was always kept relatively short and unkempt, always looking like he just got out of bed. All in all, I thought he had grown up to be a pretty handsome young man. "I signed you up for sex ed at school," I told him, after I finished eating. "Oh?" He perked up a bit at that. "Yeah, the regular sex ed classes are pretty bad, but Ms. Hernandez told me about this seminar by a famous doctor from New York." "I never heard anything about that. When is it?" "It's tomorrow, actually. They only offer it four times a year, and there were still spots open, so I signed you two up." "That's pretty soon." He mulled it over for a bit, then asked, "What do you mean 'us two'?" "You and Crystal. It's a partner course." "Oh... I guess you haven't heard. She broke up with me today." "What? Why?" I couldn't say I was entirely sorry to hear that, but it might throw an expensive wrench into my plans. "She didn't come to school today, and during lunch she texted me saying it's over." "Oh honey, I'm so sorry. That's awful." "She said she's been seeing some other guy for a while now, and just stuck around for, well, you know. I kinda figured that for a while, but wasn't sure. And after last night she said it wasn't worth the trouble anymore." What a fucking bitch. "Oh, John... I'm so sorry." "It's not your fault, I know you've always hated her. Besides, she was kind of getting on my nerves anyway." "So you're okay?" "I'm a little bummed out, but yeah. You can cancel that seminar though." Uh oh. "Shit, I actually already paid for it. Non refundable." "How much?" "Five hundred." He knew I didn't make a lot of money, and that five hundred dollars was a good chunk. That money could go a long way. We sat in silence for a few minutes, and I could tell he was weighing some options. Finally, he spoke. "This is gonna sound weird, but how about you come with me, and pretend to be Crystal. I actually want to learn this stuff, so I don't make the same mistake again, and we won't waste the money." "I suppose I could do that, it's my fault I didn't consult with you in the first place, so I guess it's up to me to make it right. The only problem," I mused, "is that it's a class for high schoolers, and I'm not exactly in high school anymore." "Don't worry, Mom. Everyone in my grade is trying to look older anyway, and uh... you actually look really pretty. Much prettier than some of my classmates." He blurted out that last part, and blushed. How adorable. "Hah," I guffawed. "That's nice of you to say, mister." Still, I felt extremely flattered by his words. "I guess that's settled then. Tomorrow it is." We spent the next couple of hours venting about his breakup with Crystal, and my favorite part, talking trash about her. By the end of the night he seemed to be in pretty good spirits again, and I went to bed that night feeling like we bonded a bit like friends, not just mother and son. Moments like that happen much less often during the teenage years, so I learned to treasure them when they do. *** The next day passed by uneventfully. I got up, ate, showered, got dressed, worked, came home, ate some more, cleaned up around the house, did dishes. You know, routine. Since we'd be going out at night I showered again, cleansing away the daily grind. Then I stood in front of my closet with nothing but a towel on, trying to decide what to wear. I was supposed to pretend to be a student, but it's been awfully long since I've been in high school myself, and I had no idea what the kids would be wearing these days. Ultimately, I decided on comfort over style, and went with simple white cotton panties and matching bra, jeans, and a nice and bright floral print blouse. As an afterthought, I also grabbed a wool cardigan in case it was too cold in the classroom. I thought about tying my hair into a ponytail, but wasn't sure if I could pull that off at my age, so I simply let it hang loose across my shoulders, thinking that the more it hid my face the better off we were going to be. I admired myself in the mirror. Not too shabby, actually. I was willing to bet no high school girl had tits like mine. It was now officially time to leave, and I collected John from his room, dressed in simple slacks and a colored tshirt. Boys always have it much easier in that department. "Do you think this is okay?" I asked him, spinning around once. "I don't want to embarrass you, showing up with your aged mother in tow." "Wow, you definitely don't have to worry about that, Mom. You could easily be in any of my classes, and nobody would notice." I just snorted. I wasn't convinced by his flattery, but I was glad to hear it anyway. When we arrived at the school, I felt a pang of nostalgia. I used to attend, back when I was young. It had since then, of course, been renovated a lot, but the layout was still the same. Room 305 was upstairs, and testing my memory of the place, I led the way. We were five minutes early, but three couples were already sitting in the room. It wasn't that big, about your average classroom size, but it was nicely furnished. Instead of the usual chairs, with small fold out desks, that I remembered from my own childhood, there were actual tables with proper chairs. A total of five of them not counting the teacher's desk in front. They were positioned in a semicircle, each wide enough for two chairs, and plenty of space between. I remembered Sofia telling me there were spots for five pairs, so the number made sense. The Important Lessons of Life I guided John to the middle one, and we sat down. Looking around the room I noticed that one of the girls shot me odd glances, but I couldn't tell if she knew I wasn't a student here, or if she was just curious. Fortunately, it seemed nobody here knew John, so my cover wouldn't be immediately blown. I grabbed my phone out of the purse to check the time. It was eight exactly. On cue, the door opened, and what could only be Dr. Sorensen entered. She was much, much younger than I expected, maybe in her mid twenties, barely older than the kids at the other tables. She had long blond hair, tied in a braid, and wore a white lab coat over a loose fitting patterned dress. "Good evening, everyone. My name is Dr. Inge Sorensen. I am glad you have decided to participate in this seminar. Over the next couple of hours, we will get to each other, and more importantly our bodies, a lot better. Let us start by taking attendance, shall we?" She spoke with a noticeable Scandinavian accent, but I couldn't identify it further than that. She then read out from a list of names, I couldn't quite remember them all. I made sure to raise my hand when she called Crystal's name, and that was that. Nobody stood up and declared me a fraud, asking why an old lady would try to pass off as a high school student. The table on the end remained empty, a certain Dave Something and Jennifer Something-else still hadn't shown up. Over the next hour, Dr. Sorensen lectured us on our reproductive system, and I had to admit she knew what she was talking about. She had a presentation of slides that showed cross sections of what girls and boys looked like, explained why we got periods, and how babies were formed, and talked about some of the dangers of sexually transmitted diseases. When she procured a banana and condom out of her bag, and demonstrated how to properly roll it on, there were a few giggles around the room, but overall it went off without a hitch. She did a pretty thorough job explaining it all, much better than I could have. When she packed away her things I thought that would have been it, but she said something that took me off guard. "Now that we have grasped the basics of sexual theory, the first half of our seminar is completed." First half? What else could there be? "We will now be moving on to the practical aspect of sexual education." What did that mean? I looked at John, and he looked as puzzled as I felt. "This may sound orthodox, but in my experience a theoretical education is not enough, and the best approach involves more than pictures and a banana. Ladies, is anyone not wearing a bra?" That was a weird question, but no one raised their hand. "Good, now I would like you to sit on the table, facing your boyfriend." There was a lot of scrambling involved as we repositioned. I sat down on the table in front of John, who remained seated. My legs were both to his side, resting on the empty chair. From this angle, I could not see any of the others. Dr. Sorensen must have pressed a button somewhere, because all of a sudden the automatic blinds descended, shielding us from outside view. "Good," she stated as the blinds came to a rest. "Now, ladies if you would please take off your shirts." What? She couldn't really be serious, could she? I was about to turn around to ask, but all around me I heard clothes rustling. Seems everyone went along with the request. Besides, it's not like I was naked under there. She had even asked if we were all wearing bras. I started unbuttoning my blouse and noticed that the room was actually pretty warm, I never even put on the cardigan I brought. Unceremoniously, I pulled the blouse over my head, and tossed it on my chair. John was fidgeting in his chair, and awkwardly stared downwards, but I could tell he was occasionally stealing glances at my exposed cleavage. I sighed inwardly, and hoped this wouldn't be too awkward by tomorrow. "Wonderful," Dr. Sorensen's voice was cheerful. "Now, boys, I want you stand up, and try to unclasp your girlfriend's bra." What? I turned my head and asked her, "Is this really necessary?" She approached our table, and replied, "Yes, certainly. I have held this seminar a number of times and this is always one of the most frequently asked question. It may not be strictly related to sex, but it is often part of the process." I sighed. She made a good point, and besides this was just unclasping a bra, I'd still be able to hold onto it with my hands. Dr. Sorensen retreated again, and John stood up. "You ok, Mo-Crystal?" he asked, almost slipping up. I nodded, and he was standing in front of me. "Uh, could you... uh, your legs are in the way," he stammered, and turned red as a strawberry. "Oh, sorry. How's this?" I opened my legs and now had one on each side of him, resting my feet on the now empty chairs. He didn't answer, but simply moved forward, and sort of hugged me. I crossed my arms and held on to my boobs, protecting him from accidentally bumping into them and to catch the bra, if he succeed. I could feel his hands fumble around with the clasp in the back. After about fifteen seconds he managed to open it, and I felt the pressure from the bra lift. "Looks like we have a winner!" Dr. Sorensen exclaimed behind me. "But do not worry, this is not really a contest." I couldn't help but feel somewhat proud, even though I didn't actually do anything. "Did you secretly practice that, John?" "It wasn't really secret, I just did it a couple times with Crys." "Oh." I wished I hadn't asked. Soon everyone else finished, and Dr. Sorensen went on, "Okay, now if you would please take off your bras we will continue with the lesson." I froze. I couldn't very well take my bra off in front of my son. John turned red again, looking off somewhere into the distance. I could hear Dr. Sorensen's footsteps approaching again, and she inquired softly, "Is something the matter?" I couldn't very well tell her the truth now. If people found out John had taken off his own mother's bra the gossip would undoubtedly spread like wildfire. He'd be finished at this school. I'd probably be finished too, and we'd have to move to another city. That would cost money. A lot of money. "Is this really unnecessary?" My mind raced, coming up with hundreds of excuses. "Oh yes, absolutely," she lectured. "It is one thing to learn anatomy from a piece of paper, but quite another to actually encounter it in real life. We want you to be prepared. Now, is there a reason you cannot do this, Crystal?" There was, but not one I could tell her. If we left now it would be pretty embarrassing for the both of us, and I did pay a lot of money to get him to learn all this. Jesus, Monica, they're just tits. I lowered my hands and bra, revealing my firm breasts. "Excellent, well done," Dr. Sorensen exclaimed, and shuffled off again. John was openly staring now, wide eyed and slack jawed. "Haven't you seen all this before?" I snapped at him, irate. I was trying to make this as easy on the both of us as I could, he didn't have to stare like that. "Yeah, but... they weren't as big as yours." I rolled my eyes at him, and he had the good grace to look embarrassed. Dr. Sorensen made the rounds to hand us all a piece of paper, printed on which was one of the diagrams from the earlier lecture. It showed an outline of a woman's breasts, with empty labels pointing at the nipple and areolas. "Boys, please try to remember what we talked about in our lecture earlier. I want you to try and identify the labels from the diagram. Ladies, please assist." John picked up the paper, but hesitated. "Come on, John, let's get this over with, then we can go home." He raised his hand, and his extended finger was very close to my skin. "That is uh, the uh, areola. I think?" His hand was trembling. "Yup! Next?" At that moment his finger brushed my nipple, and I shuddered a little, feeling goosebumps rising on my skin. My nipples hardened visibly. "Oh shit, sorry. Are you okay?" "Yea, it's just a sensitive area for us. Go on." I felt really guilty, that shouldn't have felt so good. "That," he said confidently, "is the nipple." "Yeah, two points to Sherlock." Maybe some humor would lighten the mood. Nobody else seemed to have any problems with this exercise either, and Dr. Sorensen continued. "Excellent, good job." Finally it was over, and we could all go home. "Now, ladies, if you would please remove the rest." I groaned. Honestly, I should have seen this coming. I could feel Dr. Sorensen's stare on the back of my head, and knew what she'd say if I protested. Besides, he was only going to get a look at it, it wasn't the end of the world. Better he learned this properly here and now, than by getting someone like Crystal pregnant. "Let's not make this too awkward, ok?" I told John, standing up. He was just sitting there, bright red in the face. With one fluid motion, I pulled down my pants and panties, and stepped out of them. If you had told me an hour ago that I'd be standing completely nude in front of my own son, and a bunch of strangers, I would have said you were insane. I looked around, and the three other girls were all standing there completely naked, their boyfriends obviously enjoying the sight. Dr. Sorensen made her rounds again, dropping off another sheet, and also a small pillow. The paper this time held a diagram of a woman's vagina, labels pointing at various parts. "Ladies, if you would please lie down on the table. I have provided a pillow for your head. Position yourself at the edge of the table and place your feet on your boyfriend's shoulder." I complied. The cold table warmed up quickly to my body. I scooted all the way to the edge of the table, and put my feet up on John's shoulders. He moved his chair forward, and I felt my legs spread wide open. I felt really vulnerable in this position, I couldn't believe I had talked myself into doing this. I've never had anyone who wasn't an OBGYN see me in this position, let alone my own son. Despite it all, I could feel air moving over my sensitive parts, and a familiar dampness below. Oh no, not now. What's wrong with you? John spoke quietly, "Wow, you're so... smooth." I hadn't even considered this. I get myself waxed regularly. It hurt, but I liked the way it felt afterwards. I had just gotten one done earlier that week, just before my fateful girl's night out. In this position I could barely see his face, framed by my own breasts. He was clearly transfixed at the sight of my bald pussy. I sighed again. I didn't know how I would ever live this down. "Now that everyone is in position, boys, please repeat the exercise, and identify all the parts." She made it sound so clinical. John picked up the piece of paper, and studied it for a moment, then quietly asked, "This is the... labia... majora?" "I can't see where you're pointing from here, can I?" I expected him to start describing what he was pointing at, but instead felt him press on my outer lip. Oh god, this was not happening. A ripple of pleasure emanated through my body, and I could sense a familiar ache forming. "Yes, that's it." He dragged his finger inward, slowly but surely. I couldn't believe how stimulating just a simple touch like that could be, my body started to tingle all over. "And this is the minora." He was now using two fingers and a thumb to gently massage my lip between his fingers. "Yes yes yes yes..." I closed my eyes and my breath quickened. Surely he must have noticed by now how wet I'd gotten. I tried hard to remain calm, and not betray my inner turmoil, willing my sensations to go away. I felt two fingers enter me, easily slipping in. Oh god, it felt so good. At that moment I didn't care who was doing it, I just wanted it to continue. "And this must be the vagina." "Oh god, yes," was all I could bring out. He started moving his finger out, and back in, picking up pace. I couldn't help but moan every time he plunged his fingers deep inside me, and twist in pleasure, playing with my own nipples to heighten the sensation. I could feel the onset of a powerful orgasm rushing up on me, when all of a sudden his other hand started rubbing my clit. "And that," he whispered, "is the clitoris." Oh fuck that was too much! "Oh god, oh god, yes yes yes YES!" My body was on fire, waves of ecstasy rolling over me, muscles clenching. Every light touch was amplified a thousandfold, shooting through my skin like electricity. I was lost in pleasure, shipwrecked in an ocean of euphoria. When I came to my senses again, I was still lying on the table, breathing shallowly, skin covered in a sheen of sweat. I opened my eyes, and looked around, hoping nobody had noticed my mind shattering orgasm at the hands of my son. It was futile, of course. Everyone was staring me, including Dr. Sorensen, several with mouths agape. Dr. Sorensen was the first to speak, "Ladies, what happened with Crystal is your body's natural response to stimulation." No shit. "Although perhaps not quite so intense." I started laughing softly, breathlessly, and the tension in the room broke. I sat up and without thinking what I was doing, I grabbed John's head, and pulled him in for a long, deep kiss. He was slow to react at first, and inexperienced, but he quickly learned to react to my tongue, playfully intertwining each other. "Thank you, baby," I whispered into his ear as I pulled away, "Mommy hasn't felt like that in a very long time." "That was fucking hot," was apparently the best the best he could come up with. That was fine by me, he'd already given me plenty. "It would appear that everyone has concluded their exercise," came Dr. Sorensen's proclamation. "It is now time to switch positions for our next exercise." I hopped off the table and sat down in the vacant chair. John stood before me, leaning against the table, and I couldn't help but notice the sizeable bulge protruding. Well, that was only natural of course. "Boys, please remove your clothing." Somewhere over the last few minutes I had lost most of my apprehensions about the situation, and was now very curious to get a glimpse of what awaited me. John started by pulling his shirt over his head, but I was too impatient to wait, and undid his pants. I pulled them down, memories of what I saw in the bedroom flooding my mind. He was already hard, and his cock sprang free of his pants. My god, it was so big. I put one hand on my prize, and gave it a tug, barely being able to fit my hand around it, while fully pulling off his pants with the other. Dr. Sorensen came around again, this time handing out a diagram of a penis. When she looked down at John I could see her eyes go wide, and mutter under her breath, "Lucky girl." I barely glanced at the paper, I had plenty of experience on that subject. From this position, I could see the other pairs, now completely naked. To my right the girl was already giving her boyfriend a hearty blowjob, apparently not bothering with the lesson anymore. I had the urge to do the same, but held myself back. This was all about educating John, I lied to myself. Still holding his hard cock in one hand, I moved in, and nipped at his balls. "This is your testicle." I licked the other one. "This is your other testicle." I ran my tongue up the entire length of his pole, stopping just shy of his head. "That is your shaft." And placed a kiss squarely on top, licking away the salty precum that had formed at the top. He was breathing hard now. "That is your head." "And this is a thank you." I wrapped my mouth around him, this time showing no restraint. I couldn't fit all of him inside, but I did the best I could, all the while stroking his shaft with one hand. I used my tongue to play with his head on the way up, picking up the pace of my stroking on the way down. It didn't take long before he panted, "Oh god, I'm gonna come." I could feel him tense up, and in one final effort pushed down as far as I could. He grunted, and his dick spasmed, shooting his load deep into the back of my throat. I eagerly swallowed his offering, as more and more globs of cum filled me. When he was done, I sucked every last morsel out of him, relishing the taste, and not wanting to spill a single drop. John's face was the picture of happiness. I heard clapping, at first it was only person, but soon everyone joined in. I looked around and everyone's rapt attention was focused on me, they clearly had enjoyed the performance, and I secretly hoped I had put on one hell of a show. I felt like a rockstar, not caring that I was completely nude in front of a bunch of strangers. My son's cock was my instrument, and his seed my alcohol. "Very well done," said Dr. Sorensen, and I beamed. "However, let us return to our lesson." Once again she made her rounds, handing each of us two condoms. "We will now practice the application of condoms. First the boys, then the girls." "How are you going to put that on without being hard?" "I just have to rest a little bit, don't worry." True to his word I could already start to see him growing again. God bless the stamina of horny eighteen year olds. However, when it came to the task at hand, he was having problems. He put the condom on his head, like Dr. Sorensen had demonstrated with the banana earlier, but it was far too tight to roll it down. No wonder, with how big he was. "Um, Dr. Sorensen?" "Yes, Crystal?" "Is there any chance you have bigger condoms? These are too small," I said with a massive grin on my face. "Of course, here," she replied, handing me a packet. "I only have one though, so I think it would be best if he were to practice, you seem to know what you are doing already." This time it worked like a charm, the silicon covered his erection snugly. It's a shame to muzzle that beast, but safety is the highest priority after all. "You're certainly very interested in that thing," John said. It was true. It was the most magnificent penis I have ever seen, and I didn't care that it was attached to him. "It is quite mesmerizing, dear." I wanted to rip off the condom and start sucking on it again, but Dr. Sorensen had other plans. "Alright, for the last time today let us switch positions. Please leave the condoms on, boys." Wondering what she had in mind, we quickly switched. "This is perhaps the most important lesson today. First you should get acquainted with the way it feels to wear a condom while inside a vagina." This was it. This was the last barrier that still remained between a loving mother and son. I felt a resurgence of my earlier apprehensions, this was more than just a finger or a mouth, this time he would actually be fucking me. That was wrong. But it was for his education. And anyway, he was wearing a condom, so nothing dangerous could happen. Our skin wouldn't even be touching. With this rationalization, I laid back down on the table, head resting on the pillow. I felt his tip at my slit, slowly parting my lips. Oh god, that felt so good! "Be gentle, dear, I don't know if i can fit you inside me, and remember, it's just for education purposes." As if I couldn't still taste his cum in the back of my throat. "I'll be careful, Mom, uh, I mean Crystal." I looked around frantically, but everyone was far too focused on their own machinations. Dr. Sorensen was in the process of helping out one of the couples whose condom had apparently torn. Whew. My worries were quickly pushed aside as John slowly worked his cock into me. He was going agonizingly slow, and I could feel every fraction of an inch sliding into me, stretching me. Filling me. I was overcome with the sensation, moaning as he went deeper and deeper. I felt like a part of my body that's been missing all my life was being slowly being returned, completing me. The pleasure was overwhelming, and I could feel another orgasm building up. The Important Lessons of Life "Wow, this feels amazing," he said and began thrusting in and out, adding intensity with every plunge. Dr. Sorensen's voice felt like it came out of another world as she spoke, "Ok boys, I think that is sufficient." John withdrew and I was suddenly left with a gaping void that I desperately needed to be filled. "Now, as I have told you before it is possible for condoms to break. You should be able to tell the difference from the sensation, so that you will be able to recognize it if it occurs. You need to learn to be able to distinguish the two sensations, so I want you to please remove the condoms you are wearing, and notice the difference." Oh god, I had been wrong, this was the final frontier. I came up with a thousand reason why this was wrong, but the overpowering burning need in my loins demanded otherwise. "Please," I begged him, "please fuck me. Fuck me hard." He needed no further encouragement, and re-entered me, this time sliding in easily, the raw skin contact magnifying every sensation. My own son was fucking me hard in front of a bunch of strangers. The perversity of it all brought me to the brink, promising a tsunami of pleasure on the horizon. "I'm. About to. Cum," he panted. Fuck, I was so close, but I wasn't about to let him ejaculate in me. "No baby, hold on a little bit longer I'm so close." I could feel the wave cresting, about to come crashing down in a spray of ecstasy. Not wanting him to stop, I clamped my legs behind his back, locking him in, and gyrating my hips to match his thrusting. "Fuck fuck fuck fuck fuck" he grunted, and tensed up. Just then the wave broke, and I went wild with pleasure, as his massive cock pulsated inside me, shooting his seed deep into me. "YES! Oh god, YES YES YES!" I didn't care who heard me just then, I was lost in a world of pleasure, filled to the brim with cum and joy. A torrential bliss seized every ounce of my mind. After what seemed like an eternity, I regained my other senses. John withdrew his cock, stepping back after I unlocked my feet. "Wow, that was... incredible," he said. I sat up, seeking to kiss him. That was when I noticed Dr. Sorensen rushing over. "No, no. This was supposed to be an exercise of self control, you were not supposed to ejaculate inside her!" She gestured down towards my crotch. I looked down, and sure enough his seed, mixed with my own juices, was leaking out of me, forming a puddle on the table. Still loopy from the orgasm, I reached down and started playing with the sticky mess. That's when the grim reality of the situation crashed down on me like a freight train. Oh god, I just let my son fuck me senseless, and come inside me. "I... I didn't mean to, it just kinda... happened. It felt so good..." I trailed off, knowing it was true. I loved the feeling of my son's thick cock buried in me, no matter how wrong it might be. "Attention everyone!" bellowed Dr. Sorensen. "Please be careful not to ejaculate inside your partner, remember our earlier lesson." She shot me a very disappointed glare, and stalked off to supervise the other pairs. I hopped off the table, and promptly plopped down in the empty chair, my legs were still far too wobbly to stand. I leaned back and just let the occasional after-climax ripple through my body. "Sorry, Mom," John whispered into my ear. I turned and kissed him on the mouth, which he reciprocated eagerly. "Don't worry, dear. These kinds of things can happen, now at least you know how to avoid them in the future." Seemingly satisfied with the other pairs' performances, Dr. Sorensen announced, "I want to thank you all for your participation tonight. This concludes tonight's curriculum and I hope you have all enjoyed the lecture. Please do not leave any articles of clothing behind." Everyone scrambled around the room, getting dressed. It felt surreal, standing here in normal clothes, panties starting to dampen with my son's cum still leaking out of me, next to a bunch of strangers, who just watched us having sex. We made our goodbyes, and walked to the car in silence. I wasn't really sure what to say to John, and he seemed lost in his own thoughts. We crossed a barrier tonight that could never be undone. On the drive home, John spoke from the passenger seat, "Mom, I was thinking about what Dr. Sorensen said, and I don't think I did my best. Do you think we could practice some more at home?" I smiled, knowing I'd accept just about any excuse to fuck my son again.
