Carl and Beth Do Sex Ed in Middle School by peregrinf Copyright(c) 2010 by peregrinf ------ Description: WARNING: CHAPTER 8 CONTAINS SOME MALE HOMOSEXUALITY. Beth Naked in School was one of those occasions when everything fell into place perfectly. To maintain that quality has been slow going. Good writing is like that. Sometimes it just takes time. New readers, I suggest you at least read Beth Naked in School. Even better, read the whole trilogy; in order, "Carl Naked in School", "Carl Naked in School - Beth's Story", and "Beth Naked in School".

"Good morning, Dee. You look very nice this morning. How are you feeling?" "Good morning, Ms Andrews." Even to me it sounded a little stilted, but then I was just getting used to the New Me. "I'm fine, thank you." Ms Andrews' smile warmed me. "Glad to hear it." Since getting up this morning I had been telling myself I was tall, I was slender, and I was sexy. I wasn't the stick. I was (tah! Dah!) The Stick! I told myself when you're handed a lemon, you make lemonade. I am what I am, and I was dealing with it. I AM tall. I AM slender, and, by God, AM I SEXY! Patterson was, as always, in the back row, as always slouching, as always smiling that snide smile of his, and I thought about flipping him the bird, but didn't. I was taking the high road and he wasn't going to get me down. I am The Stick. I am tall, I am slender, and I am sexy. I didn't look at Mike Collins. My "new me" wasn't quite that secure, yet. Oh, he never insulted me or anything. Never even talked to me, in fact, nor I with him. That was the trouble. I got totally tongue tied just standing next to him in the lunch line. Anyway, back to the New Me. Instead of wearing my usual baggy pants and loose shirt I was wearing a black pleated skirt that, thanks to my recent growth spurt, ended three inches above my knees. And yes I do own one -- a skirt, that is -- and a nicely pressed (well, it really was permanent press) white blouse. I had managed to tame my hair for the moment, and wore just a hint of make-up. I was tall. I was slender. I was sexy. I was The Stick and proud of it. I'd thought of coming to school naked this morning, but Carl talked me out of it. He didn't think that Middle School was quite ready for that level of sophistication. Their loss. I was also not so foolish as to attempt a frontal assault on Mickey by wearing a tight sweater. I went for class, not flash. Better, I thought, to let the audience's imagination fill in the blanks. And yeah, I admit that conflicts with my idea of coming to school naked, but it's a girl's right to change her mind. I was glad I hadn't. Sure, I'd been naked at home a lot, naked with my brother, naked and masturbating with my friends at the sleepover, but being the only naked girl in the whole school was a whole 'nother can of worms. Besides, it would have clashed with the dress code of the school district, what remained of it now that the NIS program was going into its second year. As I settled in my chair I glanced around, feeling somewhat superior. After all, after yesterday with Carl, how many of them knew what I knew about Good Sex? Poor fools, how much they had to learn. "Have you heard what they're calling us in the halls?" Missy asked me as she slid into her seat beside me. "Who's 'us'?" I asked. "You know, US! This class?" I'd been aware of some whispers, but hadn't really listened this morning. After all, I was The Stick. I was tall. I was slender. I was sexy. But Missy's question brought me down off my high horse and I realized I was behaving like a real dork. This was my BFF Missy I was talking to. Was I stooping to Mickey's level? That would never do! "No, what are they calling us?" "The Dirty Dozen," Missy whispered conspiratorially. Good word, that, "conspiratorially." We'd had it in language arts last period. "They're calling us what? And who is this 'they'?" "The other kids, the kids in the hall, they're calling us in this class the Dirty Dozen!" I couldn't help it. I burst out laughing. "Really? How cool is that!" "I think it's terrible! They're saying all sorts of disgusting things are going on in here!" "All right, let's settle down in here," Ms Andrews called as she again drew the shade over the window in the door. I was still laughing. "Time's a-wasting here folks. Care to share the joke, Miss Walker? I thought not. Patterson, button your shirt. By comparison your display makes Mr. Walker look like Arnold Schwarzenegger." I didn't bother to turn around. I'd seen Patterson's attempts at beefcake before. Compared to my adornments he was positively concave. After suppressing giggles thinking of Missy's news I studied the conference table's setup, trying to figure out what we were in for today. The top of the table was covered with a white cloth, and there were some towel covered cushions arranged against the wall. That looked interesting. The projection screen was down. Movies perhaps? But then why the cushions and sheet? I come from good stock. We Walkers were not dummies. I put the pieces together. Couldn't be anything but. We were in for some wide screen, hi-def show and tell. If so this was the right venue. The room was known for its cutting edge multi-media facilities. There was a ceiling mounted digital projector, a remote controlled hi-def video camera, and everything tied into the school's fiber network. I hoped the geeks entrusted with digital security had done a good job of fire walling this room from the network in general. If not there'd probably be a school wide riot. What would a DVD of this session bring on eBay? Not that eBay would ever let such a thing come to auction, of course. But you can bet it would go viral on YouTube faster than the dancing baby. This morning it was Beth that looked stressed out, while Carl was all loosey goosey as they took their places in front of the table. Beth looked like she was filled with worms. She clutched Carl's hand like a lifeline. I wondered why. After all that she'd done during her week in The Program -- from posing nude in art class, to leading a pep rally naked, to urging the football team on to victory with her own naked body, and then paying off by being their fuck toy, what could top that? This should be a piece of cake -- cheesecake. I take that back, partly as a disservice to good cheesecake. Beth didn't have the attributes of a calendar girl. She is also too dignified for that. Besides, what she'd been doing went far beyond cheesecake. Beth took a deep breath. "Now, before we continue, are there any questions?" Mickey was out of the blocks like a sprinter. Not that she was built like one. Too much wind resistance with her super-structure, to say nothing of too many moving parts. "Are we going to have to get naked in front of the whole school?" As she asked it Mickey somehow managed to jiggle back and forth between bashfulness and eagerness with every deep, chesty breath. Ms Anderson quickly rose to field that question. "The details with respect to nudity in Middle School are still under discussion by The Powers That Be. At your age it is a controversial issue." "But..." "I shall say no more about that at this time, Miss Kelly." Ms Andrews's tone of voice cut off that discussion. Answered like a politician. Something interesting was obviously brewing on that front. "Thank you." Beth surveyed the room. "Are there any more questions? If not then let's continue where we left off. Carl?" "In the first class we explained the reason for this class, and brushed the surface, so to speak, of the anatomical differences between male and female," he began pedantically. Obviously they'd scripted it. Beth snorted. "Give it a rest, Carl. We did a little show and tell. Today we're going to go into that subject in more depth, you might say." She removed her robe. I probably wasn't the only one who noticed a little shiver as she did. As usual, there was a rustle of excitement from the class. Ignoring it she turned her back to spread her robe on the table, giving us a very nice view of her smooth, nicely rounded butt as she did. I may be The Stick, but I hoped I'd have as nice an ass someday. "Take it off, Carl," Beth ordered, turning back around, eyeing the erection tenting out the robe he wore. "Everyone knows that's not a banana in your pocket." With a mock grumble, he did, releasing his cock to swing and sway like a homing torpedo seeking a willing target. Mickey smacked her lips. Down girl! Catching Carl's eye, I shared a look and a wink with him, and he winked back. Then I gracefully crossed my slender legs, letting my sandal dangle invitingly from my toes, and no, I had not painted my toenails -- yet. How my skirt happened to slide so far up on my thigh only my fingers knew. Carl tried to frown at me. Beth shot him and me a curious glance as she boosted herself to sit on the table where she'd spread her robe. She obviously suspected something had gone on with us. Well, I wasn't going to tell her, and I knew Carl wouldn't. As for my legs, Mickey shot me a surprised look, but otherwise everyone's eyes were on Beth's and Carl's greater displays of flesh. "Since girls are more complicated down here," Beth pointed to the puffy bare lips of her pussy, "we'll start with me. If we have time we'll take up Carl's equipment later in the hour." Ms Andrews dimmed the overhead lights, leaving a spotlight on Beth, and the projection screen lighted up. After a bit of squirming by Beth and some adjustments by Ms Andrews, Beth's image appeared on the screen. Or more accurately, the spotlighted area of her from her thighs to her belly button. Oh my! We were going to get very up close and very personal with her anatomy. No wonder she was antsy. I saw her lips moving and wondered if she was having a conversation with her Evil Twin. She'd told me once that her Evil Twin was the one who kept getting her into these outlandish sexual adventures, such as taking on the football team. According to her, Evil Twin thoroughly enjoyed these decadent romps, the implication being she didn't. Right. I'm not a shrink, but I'm reasonably certain she does not suffer from a split personality. Not for me any scapegoats. No sirree! The Stick assumes full responsibility for all of her debaucheries, should she be lucky enough to ever have any. Which, of course, she would, for she is The Stick. She is tall. She is slender. She is sexy. I shut down that train of thought when I realized it made ME sound schizoid. I am The Stick, The Stick is me. We are one. Ommmmm, ommmm, ommmmm. Imagine me folding my long, slender legs into the Lotus position and it works better. Carl adjusted the cushions for her back and she leaned back, lifted her feet to the table and spread her legs. Oh my! I recognized the pose, although I was still at the pediatrician stage, to my chagrin. Not that I was eager to have someone probe me down there in a cold, clinical fashion, mind you. It's just that, well, I'm almost thirteen! Don't you think that's a bit old for a baby doctor? And remember, Carl's appreciation of me had been sensual, very sensual, rather than clinical. Anyway, Beth was about to give us a preview of what we ladies faced in the near future, though I was willing to bet Mickey already knew. Beth's fingers scratched nervously at the cloth covering the table as she tried to get comfortable. She was blatantly on display on the projection screen, in living color, about four feet wide. Already her pussy was licking its lips, metaphorically speaking, her inner labia happily presenting themselves as shiny pink ruffles between the rounded plush of her outer lips. I had to admit it was a tantalizing display, one I'd never seen in such detail. My own landscape down there was still pretty much a mystery to me. I'd tried a mirror, of course, but that hadn't really worked very well, and Missy and I had always been shy with each other. This was really detailed, and something about it reminded me a little bit of something I'd seen not long ago, but I couldn't remember what it was. "We're going to use some of the formal terms today. These are the labia, the outer lips." To my surprise, Carl wasn't using any kind of device, but instead actually touched Beth as he described what we were seeing, and she reacted accordingly. "As you should know by now, as you mature hair will begin to grow there. As we said before, Beth shaves hers. Between the outer lips you can see the pink ruffle of her inner labia. Generally these show only when she's aroused." His finger actually traced those pink petals, and so much for Beth's often expressed "scientific detachment." She shivered. She was getting turned on by this, and her mythical evil twin had nothing to do with it. She was horny! No surprise, really, considering how she and Carl went at it. But this was in front of a class. If that's not exhibitionism, what is? Evil twin my skinny -- tight -- butt. Carl used the fingers of his right hand to part her outer lips, exposing the interior, and I got more of a flash of that feeling I'd seen something like this somewhere before. As if trying to distract herself, Beth looked over at Carl, her eyes going to his jutting hard on, and she licked her lips. Carl's cock responded by drooling. What a randy pair they were. "This is Beth's urethra," Carl pointed out, "above the opening to her vagina." "My vagina," Beth went on a little shakily, "is where the man's cock goes in during sex, and where the baby comes out, nine months later if all goes according to plan, or not, depending on what the plan was at the time of intercourse." "That's assuming that any planning was done before passion took over," Carl added. "And planning, by the way, is a good idea." "But since God saw fit to give man a brain and a dick, but not enough blood to run them both at the same time, planning is frequently in short supply on the male side," Beth noted. "That leaves it up to us, ladies, and I strongly urge you to think about it well before you get into a situation that may lead to intercourse. "But, anyway, given that a baby emerges from there you can assume that the vagina is capable of opening quite wide." "And conversely, it is capable of contracting to provide a nice, snug place for my hard on," Carl added. I squirmed, and others did, too. This was getting very personal when it came to talking about sex. Carl's finger ventured lower. "And just below Beth's vagina is her anus," he pointed out, actually touching that tight little pucker. It winked in reaction. "Which, by the way, is sexually sensitive as well." "But I ask you, is it intelligent design to locate a playground between the sewers?" Beth put in wryly. There was nervous laughter. The whole "intelligent design" issue had recently been hotly debated at a Board of Ed meetings. I was willing to bet, though, that there were no children of intelligent design advocates in this class. Just the Naked in School program had been enough to boost the enrollment of both home schooling and some of the church affiliated schools. "This arrangement can result in some unpleasant infections should there be transfer from asshole to cunt. Be careful to wipe down and away, ladies. And don't let your partner explore your ass and then your cunt with the same probe without thoroughly washing him." Carl's finger traced the line of Beth's inner lips upwards, and settled where they joined to form a little hood. With every touch Beth writhed. "And here is where we find the clitoris," he explained. "Right now it is hidden under this little hood, but as her arousal increases it becomes more erect." "It is sort of like a little penis in that way," Beth added, her voice a little shaky as she focused her look somewhere above the ceiling. Her tits were positively swollen. "And it is the firing pin, so to speak, of the female's orgasm," Carl went on, fingering Beth just above her clit, retracting the hood. Beth was juicing up nicely. "Most women react strongly to contact with their clitoris. During intercourse, depending on the position we're in, it is trapped between the man's pubic bone... ," Using his finger he traced the arch above his own penis " ... and the woman's." He traced the arch of hers just above the top crease of her pussy, while still holding her labia open. "Or one of the parties may manually stimulate it," Carl concluded. I still couldn't' shake the feeling I'd seen something that looked like the geography of Beth's pussy someplace, just a fleeting glimpse. There was a knock at the door, and Beth got that deer in the headlights look again. Ms Andrews opened the door to admit a woman carrying a sort of caddy. In moments she had unpacked the carrying case, plugged in a couple of things, pulled on some latex gloves, and was wielding something that looked vaguely like the neck and head of a duck in one hand, a snaky sort of cable in the other. When she squeezed and released the duck's neck the duck's bill opened and closed. "My name is Dr. Smathers, and I am Miss Finch's OB/GYN. This is a speculum," she explained, flapping the duck's beak. "When you have a pelvic or rectal exam it is used to dilate, or open, the passage." Oh oh, I thought. "And this is an endoscope," she went on, waving the snake like thing around in her other hand. "It is used to look inside the body. In this case it is attached to a video camera, which is attached to the computer like a web cam, so the image can be projected up there." She indicated the screen above Beth's head. Oh my! Beth swallowed hard, and reached for Carl's free hand -- the hand that wasn't holding her cunt open, that is. This was indeed going to be an in-depth look at Beth's pussy! I always wondered what the tunnel of love looked like, I thought, suppressing a nervous giggle. There were some whispers going around the room as well, until Ms Andrews rapped the table. "Don't panic, ladies. This is not a common procedure for a young woman's first gynecological examination," Dr. Smathers went on. "Miss Finch has very generously volunteered to give us a look inside her vagina. Are you ready, Beth?" Beth nodded about as willingly as Joan of Arc probably had at the sight of her stake. Talk about exhibitionism! She laid her head back again, still clutching at Carl's hand, as the doctor gently slid the speculum into Beth's cunt, and squeezed. The bill opened, and Beth's vagina yawned. The view on the screen shifted to the endoscope's view, showing Beth's gaping opening. "Just try to relax," Dr. Smathers said softly, slipping the head of the endoscope in. Beyond the hard leaves of the speculum there was a rippled, glistening pink tunnel -- her vagina. Though she tried to remain still, Beth's hips lifted, legs opening wider. Whether she'd admit it or not, she was welcoming the invader. My own pussy creamed at what that must feel like, to be stretched open, and then that hard snake of the endoscope brushing inside, and I squirmed my thighs together nervously. The room was absolutely silent, the entire audience holding its collective breath. It only made Beth's soft moan seem all the louder. "The female vagina," the nurse pointed out, "is also the birth canal. It is capable of stretching to let a full term newborn baby through, so this intrusion is minimal. "When stimulated by foreplay, kissing and petting for example, the woman's body prepares for intercourse by secreting lubricating fluids. Once it is so prepared it can easily accommodate even the above average sized penis. "As you can see by the copious secretions in her vagina, Miss Finch is aroused, possibly by this penetration, but more likely she has been stimulated, physically or mentally, by what has been going on earlier in this class. Physical stimulation is not necessary. It has been accurately said that the brain is the most important sexual organ. "The vagina is quite sensitive, and without lubrication intercourse is painful. The first time for a woman often involves some discomfort, owing to the presence of the hymen. "In this case, virginity is not an issue. Were Miss Finch a virgin there would likely be a thin barrier of tissue at the entrance to her vagina. Her sexual activities have dispensed with that impediment." I was juicing like mad just watching Beth accept that intruder. She was obviously aroused, her nipples stiff, her pussy soaking wet. She was breathing hard, licking her lips, clinging to Carl's hand. With his free hand, Carl was taking liberties with Beth's gaping twat, his own cock drooling eagerly. He stroked her slick folds, teased her clit, all the while watching the screen behind Beth's head as it showed the endoscope's progress. Very slowly the probe tunneled deeper, revealing her deepest secrets. It was all I could do to keep from sliding my hand into my panties and probing my own cunt. I could hear the excitement around me, whispers and moans. I don't think there was a dry pair of underpants, male or female, in the room. "At the far end, as you can see," the doctor continued, "is the cervix, that rounded intrusion. In the center of it is the opening to her womb, where the baby develops. "At climax, during intercourse, the boy's semen containing sperm is released deep in the vagina. The sperm swim upstream, so to speak, through the narrow opening of the cervix into the uterus, or womb, and then even further, up the fallopian tubes which convey the egg, or ovum, to the uterus. Somewhere along that journey, if the woman is ovulating, the sperm encounter an egg, and one lucky fellow fertilizes the egg, and the baby starts to grow." The image on the screen jiggled, and Beth moaned. "Sorry," Doctor Smathers apologized. "As you can tell, the inside of the vagina is quite sensitive." "It's -- all right," Beth gasped. Carl whispered something to her and she shook her head. "Don't you dare!" she whispered loud enough to be heard by at least half the room. "Don't do this?" he asked, his finger teasing her clit. "Stop it!" Beth pleaded. "You don't want me to do this?" "NO I -- OOOOOOOHHHHH GOD! YOU DID IT! YOU DID IT! EEEEEEEEEEEEEEEEEeeeeeeee!" I know I was gaping like an idiot, because I knew Beth was cumming, right there, in front of the whole class. She was squirming, writhing, wailing. A flush blossomed upwards from her humping hips. And, thanks to the endoscope, we could all see the walls of her vagina spasming as if it were milking a cock instead of the endoscope. Oh wow! I was so jealous! Not that I wanted to make an exhibit of myself, but I sure did want to feel what she was feeling at the moment. I remembered the delicious flames I'd felt just the afternoon before, thanks to my brother's skilled tongue and finger. Carl was right. Now when I felt that hunger I knew what I was hungry for. "WHOOOoooooooooo," Beth sighed. Looking lovingly up at Carl she giggled nervously. "I'm gonna get you for that you know." He squeezed her hand, and kissed it. "I'm looking forward to it." I couldn't help it. I let out a "woo hoo" of my own and applauded, the class joining in as Doctor Smathers extracted the endoscope and removed the speculum, leaving Beth's cunt glowing from her orgasm. Dr. Smathers discretely wiped down her instruments, stripped off her gloves and slipped away as Beth let her feet slide off the table and, with Carl's help, sat up. "Well," she said, "you've now seen a woman's orgasm from the inside. Something I've never seen before myself. Since I was busy enjoying it, I'm looking forward to the instant replay." She glanced at the clock. "But, since we have a little time left, let's examine the male organs in more detail than we did in the last class. Carl, if you please." She slid off the table and moved out of the way, steadying herself with a hand on the table, her legs obviously rubbery. He had a chagrinned look as he took her place, his erect cock jutting up from his lap. He adjusted his position so the video was focused on his hard on. "As you can see, Carl is fully aroused, and the male structure is much more exposed than mine," Beth began. "While most of my sexual organs are internal, his -- well, it is where we get the term 'let it all hang out.' Isn't it Carl?" Blushing, Carl nodded, shifting on the back rest. In response to Beth's gesture, he lifted his feet to the table, his knees apart, his balls sagging between his thighs, his ever so rampant cock resting up against his stomach. On the screen it was humongous. "There's a lot more behind the curtain, so to speak," Beth went on, "but Carl doesn't have as convenient a window on the scene as I provided, so we'll ignore that for the moment." "Obviously we have no problem bringing Carl's cock to attention, after the show I put on. These," Beth continued, "are Carl's testicles, or balls." She fondled them, letting them slide back and forth on her fingers. "They are contained in this sack, the scrotum. His balls produce, in addition to sperm, hormones, the chief of which is testosterone, the hormone that makes a man behave, well, like a man, all hairy chested and competitive." She wrapped her hand around his testicles and squeezed gently. "The balls are also sensitive, so remember ladies, if you can get him by his balls, he's at your mercy." Carl winced. She cupped her hand under his balls and lifted them. "Behind them, as you can see, is Carl's anus -- his ass hole, if you will." Deliberately, she scratched at it very lightly. "And, in case you're interested, it is an erogenous zone for the male, just as it is for the female. The little bit between his anus and the base of his scrotum is another erogenous zone." She scratched it lightly as well. "Very sensitive, isn't it, Carl." He nodded uncomfortably, and I noticed he was sweating, and so was I. I was reluctant to admit it, but I, The Stick, was drooling, literally. I'd heard about cock-sucking, but never felt the urge before. "From the testicles, or testes, the sperm is stored in a series of vessels in the scrotum, then flow through tubes, called the vas deferens, up the scrotum then inside his body," Beth continued to fondle his testicles, "to the prostate and a complex of glands inside his pubis." With her free hand she cupped the area around the base of his cock, then stroked up to curl her fingers around his throbbing hard on. "While I'm not going to do it, the prostate can actually be palpated -- indirectly massaged -- by inserting a finger in Carl's anus. This can actually trigger an orgasm, but I'll not do that here, at least not now. Aren't you relieved, Carl?" He nodded goofily as she fondled his cock affectionately. "The prostate is actually a muscle and a gland. It acts as a valve between the bladder, which holds his urine, and his cock, which contains the urethra, which does double duty as a delivery channel for both his semen and his piss." She kept her hand moving on his cock. "Glands adjacent to the prostate, called seminal vesicles, generate seminal fluid to convey the sperm, and the prostate also acts as a pump to propel it. The prostate is a busy puppy, you might say." She stroked her thumb over the head of Carl's cock, which had been leaking pre-cum even during his play with Beth. "In fact, it's very difficult, if not impossible, for a man with an erection to piss. Isn't it Carl?" Again he nodded, beads of sweat on his brow. "Uhm, Beth?" "Don't interrupt, Carl. Yes, well, now the cock becomes erect when blood flow out of it is restricted and the arteries and veins within relax and become distended." She squeezed his cock. "While a hard cock may be called a boner, bone has nothing to do with it. "And, as you can see, it leaks a lubricating fluid produced by the Cowper glands, again near the prostate. Pre-cum greases the way, along with the female's own secretions, making intercourse more comfortable for all concerned." She kept stroking her thumb over the purple-ish head of his hard on, making it glisten, making Carl sweat even more. "Now, one thing to bear in mind is that this pre-cum often contains some sperm cells, long before the man ejaculates -- that's fancy talk for cums. For that reason, girls, beware! You can become pregnant even if he actually keeps his promise and pulls out before he cums! If you don't want to become pregnant and haven't taken precautions, don't let him in your vagina at all! Period! Exclamation point! "Furthermore, sperm are highly mobile. Even if he doesn't penetrate you, if he cums near the opening to your vagina, even completely outside your body, one of those enterprising little wrigglers could swim all the way up the length of your vagina, through your cervix to your uterus, and further. And somewhere along the way it might encounter one of your eggs. "If that happens you are on the road to becoming a parent." She continued to toy with his cock. "The head of his cock, called the glans, is his version of my clitoris. It is loaded with nerves, making it more sensitive than the shaft," she went on, still stroking his cock, "with the most sensitive bit on the underside, just below the head, here." She tilted his dick back to indicate the spot, and tickled it lightly. Carl groaned. "Uh, Beth?" "Hush, dear, I'm talking! As you can obviously see, at the tip of the head is a slit," she bent his cock toward the class and toyed with the tip delicately, "which is the opening that both semen and urine come from, depending on the demands of the situation. "As you know, urine is usually yellow, while semen is white. That's so a man can tell whether he's cumming or going." Angling his cock back toward his belly, she began stroking his shaft. Ms Anderson zoomed out to show more than just Carl's crotch. "Beth, don't!" "Shush, Carl! Not now! And that's the essential biology of the cock," she went on sweetly as Carl squirmed. She tilted his cock more vertically. "The man inserts his cock into the woman's vagina, and moves it in and out, in and out, the friction stimulating the shaft, and more importantly the oh-so sensitive glans, until ... oooops!" Her timing was perfect. Carl let out a groan as his cock throbbed in her hand, pulsed, and shot a thick stream of cum so strongly that it splattered on his own face, where she, not so accidentally, had been aiming his hard on. The following spurts lacked the first's enthusiasm, splattering his chin, chest and stomach with thick, creamy blobs of cum. "Oh dear, did I do that?" Beth asked innocently, drawing guffaws from the class, along with one or two "eeewwwws!" and one "Yuck!" from some of the younger girls, as she finished milking his shrinking dick, the final oozings coating her fingers. Presumably not wanting to leave the class with an unpleasant impression, she dipped her head, and sucked the seepings off his glans. Smacking her lips, she also licked the overflow from her hand. My mouth watered, and I wondered if I could con Carl into letting me suck him off. After all, he'd done me. I certainly owed him that much, didn't I? "It tastes a little salty, sometimes just a bit bitter," Beth admitted. "I like it. It is best still warm and fresh directly from the source, of course. "Now that Carl is done cumming, you'll note his cock is shrinking and softening. Unlike us ladies, he carries a single shooter -- one orgasm and the man is usually done until he recharges his batteries, poor baby. It may take a few minutes, even hours! Whereas we women are not hampered by such weaknesses. We can have multiple orgasms, one after the other. We can keep going and going and going, like the Energizer Bunny. Or should that be cumming, and cumming, and cumming?" Casually, she wiped her hands, then handed Carl the same towel she had used, just as the bell ending the class went off. "Thank you for being so attentive," she concluded, grinning at Carl as he mopped the cum off his face and torso. "We'll continue our exploration of sexuality next time." We gave her and Carl a hearty round of applause as they donned their robes before Ms Anderson opened the door to the hallway. I couldn't resist catching Carl's eye. I licked my lips, and he flushed, and smiled. I let my hips sway as I sauntered out the door with the rest of the Dirty Dozen.
