Chapter 2: A Discrete Lesson

Bart woke up to the sound of a shower running. He was lying alone on the king size bed in his parents' bedroom and recalled what had happened yesterday. So it hadn't been a dream. He had really frotted his own mother's ass last night while she was sleeping. And now she was in the shower washing off his cum.

It's probably better that I avoid her today. She probably won't be able look me in the eye for a while.

The boy got dressed and went downstairs. There was no need to worry about his mom bringing up what had happened. She would soon enough be brainwashed anyway. If she thought that 'nocturnal emissions' were the most embarrassing thing she would ever experience with her son, she was in for a surprise.

When Bart got in the kitchen, Lisa was already sitting at the table.

"Good morning, my beautiful little sister," Bart said flamboyantly. It felt so good to know that soon all of his troubles would be over.

"Did you just call me beautiful?" Lisa cocked her head incredulously. Her expression then changed into a judgmental frown. "What are you planning this time, Bart?"

"Oh, nothing," Bart smiled, stroking Lisa's spiky hair gently. "Is it so strange for a brother to notice what a beautiful specimen his sister has become?"

Lisa couldn't hide her blush, but she brushed Bart's hand away. "You're definitely up to something. You're acting weird."

Bart shrugged nonchalantly and poured himself a cup of cereal.

"By the way, where's mom? Shouldn't she be making us breakfast by now?" Lisa asked.

"Mom's taking a shower," Bart answered. "It's not like we're babies. We can't expect her to pamper us every single morning. She already has enough work to do around the house as is."

"When did you become so mature?" Lisa said with a slight smile. "Whatever you're scheming, I hope to see more of this side of you."

Bart's heart skipped a beat. Lisa might have been an obnoxious know-it-all, but she could also be incredibly cute at times. He recalled the time when he had really hurt Lisa's feelings by destroying her Thanksgiving centerpiece. But when he finally swallowed his pride and apologized to her on the roof, she had kissed him on the lips multiple times. It had felt so good. Those moist lips of an innocent child who happened to be his little sister. Come to think of it, she had stolen his first kiss. Not that he minded, of course. Maybe if he himself wasn't such an immature troublemaker Lisa might kiss him more often. But it was hard to rewrite their relationship's established sibling rivalry. At this point an honest compliment coming from him could hardly sound sincere.

Bart looked at his sister's soft lips longingly. Kissing certainly wasn't the only thing those tender lips would be good for, but right now he simply wanted to hug the gorgeous little girl and give her a passionate, long smooch that conveyed all of his feelings for her. Sadly, he knew that if he were to just kiss her out of nowhere, she would probably punch him. And if she knew of the picture he had taken of her while she was sleeping, she would kill him…

Bart finished his cereal and headed for the door, but just then Marge came down the stairs, carrying Maggie.

"Bart, could you wait for a second?" she said, her hair still moist from the shower. Bart froze, hoping she would not bring up last night.

"What is it, mom?" he asked, feigning ignorance.

"Well…" she hesitated. "About you sleeping in the same bed with me and your father… how do I put it… I think that you're at an age where you should… sleep in your own bed, because…"

She was beating around the bush big time. Bart's face was red with serious second- and first-hand embarrassment. "Mom, I get it. I'll sleep in my on bed from now on."

"It's not that we don't love you," Marge continued. "And if you ever have a bad dream, you can come wake me up and I'll give you the biggest hug to make you forget all about it… It's just that… boys, when they reach a certain milestone… begin to experience things in their dreams… that could result in certain… fluids coming out."

"What, did Bart wet the bed again?" said Homer, coming down the stairs. "Heh-heh-heh! Don't worry, boy! Happens to the best of us."

Bart thanked the heavens for his father being so oblivious. Homer was known to strangle Bart for much less than what he had done last night, so his stupidity came in handy now. Lisa, on the other hand, had been rubber-necking the conversation from the kitchen and had a clearly disgusted expression on her face.

Crap. She totally knows what mom's talking about! She knows I slept next to mom and came on her!"

"A-anyway, I gotta go, mom. See you." Bart rushed outside with his heart in his mouth. The school bus wasn't going to arrive for at least ten more minutes, but he had to get out of that insanely awkward situation as fast as possible.

Son of a beachball! Why did she have to bring that up in front of Homer and Lisa?

Bart's misfortune continued at school. Because of last night's excitement he had not gotten enough sleep and ended up falling asleep in class. As a result, Mrs. Krabappel gave him detention. So, after school he was sitting in an empty classroom with just Mrs. Krabappel at the podium.

Damn it! Everything went so smoothly yesterday, but today really sucks so far.

He was sitting near the back of the class and Mrs. Krabappel wasn't really bothering to supervise his behavior. She was absorbed in some kind of a fitness magazine. This gave Bart the opportunity to get away with using his phone. He was playing a puzzle game under the desk to pass the time, but eventually even that got boring. Looking at the clock he came to the shocking realization that only thirty minutes had passed.

Bart cursed his attractive yet overly strict teacher in his mind. An hour of detention just for resting his eyes for a couple minutes was way too harsh!

If our roles were reversed I'd be the one punishing her. I'd bend her over a desk and give her a good spanking for being such a bad teacher. I'd make her hang upside down and roughly face-fuck her. I'd go balls-deep in her whore mouth and force her to gulp every last drop of my semen down her throat.

The empowering sexual fantasy gave Bart an idea. Since his desk was so far from the podium and Mrs. Krabappel wasn't paying attention, nothing was stopping him from spending the last thirty minutes of detention masturbating. After checking that Edna still had her eyes glued to the magazine, Bart pulled his cock out of his shorts. But he also needed something to clean up his eventual mess. So he removed his right shoe, took off his sock and put it on his dick. He then put his bare foot back in the shoe.

Hmm, yesterday I came to mom's tits and ass, so today it's Lisa's turn. I'm gonna stroke it to my jailbait sister's cute booty.

With that decided, he pulled out his phone and opened the picture he had snapped last night in Lisa's bedroom. The dark lighting left something to be desired, but just the idea that he had managed to get a secret photo of his underaged sister's tight ass was hot enough on its own.

Once I get the HypnoBox, I'll definitely train her for anal. Maybe start with smaller toys before moving to butt sex. It'll take some time, but she's a hard worker, so she'll definitely become a pro with a little practice. Lisa's age never stopped her from achieving big things!

"You having fun there, Bart?" Mrs. Krabappel asked. Her voice was coming from awfully close. Bart locked his phone screen and raised his gaze in terror. Mrs. Krabappel had somehow walked all the way up to the front of his desk without him noticing. From the angle she was looking down on, she probably couldn't see what he had been looking at, but he had his cock pulled out with a sock hanging on it just underneath the desk. If Mrs. Krabappel moved to the side of his desk she couldn't miss his shorts being pulled halfway down. "I thought I told you that phones weren't allowed. Hand it over."

Bart reluctantly gave his phone to his teacher. The screen lock used fingerprint identification to unlock, so she shouldn't be able to open it and see the picture. He was sure he had locked the screen, but on the off-chance that he had screwed up in his panic, he could be in trouble… Even if it was just her backside, the half-naked girl in the picture was clearly Lisa Simpson, probably the most famous student in Springfield Elementary. Edna would immediately recognize her and become privy to Bart's infatuation with his sister's derriere.

"Now, what was so important that you just had to pull out your phone against my clear instructions?" Edna asked.

"I was just reading up on world-history, Mrs. Krabappel!" Bart fibbed. "I've been really getting into the Renaissance period recently. Really fascinating stuff!"

"Ha!" Edna gave her mocking signature laugh. "YOU of all people interested in history? You must really think I'm dumb to think I'd fall for that."

"No, I've really decided to turn a new leaf and apply myself," Bart insisted.

"Oh really?" Edna mocked, leaning on his desk with both hands. "Then tell me who your favorite Renaissance painter is."

"It's uhh… There's so many, it's hard to choose just one…"

Edna smiled smugly. "Oh, Bart, you never change. And neither do I. We are the same in that way. You'll always be a troublemaker who doesn't care about schoolwork, and I'll always be a disillusioned educator who has been an elementary school teacher for too long to seek another career path."

"I'm sorry for always causing you trouble," Bart apologized sincerely. "You're really a great teacher. It's not your fault that I'm such a screw-up."

Since the fibbing wasn't working, maybe the ashamed puppy-dog look would get Mrs. Krabappel off his case. His other hand was still around his erect penis after all, and her leaning on his desk exposed so much of her cleavage that it looked like her breasts might jump out of her blouse any moment. He had been so close to finishing when she had interrupted his fapping. If he didn't get her to go back to the podium soon he would get blue balls.

"You really mean that?" Edna said. It looked like the compliment had worked. But instead of going back to the podium, she leaned even further forward on Bart's desk. "What part of me makes me a great teacher in your opinion?"

At this point the boy couldn't help staring at his teacher's boobs. Either she didn't register Bart as a heterosexual young man at all or she was doing this on purpose! It was like she was telling him to finish what he had started. Bart started stroking his cock under the desk while trying to think of an answer.

"I like how big your… heart is," he said while openly leering at Edna's hanging tits that were gently swaying from side to side. It wasn't his fault if she was pushing them this close to his face. "You always look after your students. Even when you treat them harshly, you do it because you care about their future. Tough love and all that."

"Wow, Bart! That's surprising insight coming from you. That's exactly my approach to educating!" Edna exclaimed, jumping excitedly like an eager school girl. This caused her breasts to bounce wildly to the extent where Bart almost passed out from arousal.

Oh yeah, keep bouncing those titties, you whore! You took my fap material, so I've earned a good show. Keep squeezing those juicy bazookas against my desk until I blow my load, you shameless cumslut.

While Bart was stroking his member intensely Edna continued her ranting.

"My friends keep telling me that elementary school students need to be nurtured and encouraged, not scolded! But that's how you get a generation of entitled brats who cannot take criticism! You've got to show the children who's boss or they won't listen. They might hate you now, but they'll appreciate it in the future. Finally someone who gets it!"

Bart forgot for a second that he was in the middle of masturbating furiously. He hadn't expected his little compliment to make Mrs. Krabappel so happy. It was really nice to see this side of her.

"Bart," Edna said, having composed herself. "I know we've had our differences, but I think that deep down we understand each other. If you ever need anything, just let me know, okay?"

"Sure. Thanks, Mrs. Krabappel."

Wow, I gave her one half-assed compliment and she's pudding in my hands. I never knew how much she just wanted someone to show that they appreciate her work.

"Is there anything you need help with right now?" she asked, leaning forward on his desk again.

Oh my god! Is she coming on to me? Does she know that I've been stroking my dick under the desk this whole time?

"Umm, there's this one thing I'm working on right now," Bart said with the pulsating dick still in his right hand. It was better to keep his words intentionally vague in case he had misread the situation.

"Is it... hard to talk about?" Edna asked.

"Yes... very hard."

"It might feel good to get it out of your system, though."

"Yeah, definitely! But all I really need for now is a little encouragement."

"Encouragement, huh? What should I say?"

"Just tell me I can do it."

"Okay then," Edna shrugged with a smile. "Come on, Bart! You can do it!"

She's telling me to do it! She's telling me to come!

Bart considered taking off the sock and standing up to shoot his cum all over his hot teacher. But that was too risky. Although everything up to this point could be construed as subtle dirty talk, there was still the possibility that Edna had no intention of seducing her student and was blissfully oblivious to the sexual tension in the room.

"Thanks, Mrs. Krabappel. Your encouragement really helps. But you always seem so depressed that I think you should also encourage yourself. Cheer both of us on at the same time."

"Umm, how do I encourage myself?" Edna asked with visible confusion.

"Just do the same thing you did for me. But instead of saying 'come on, Bart', you replace my name with your own."

"You want me to cheerlead for myself? I guess that could be therapeutic. Well, here we go. Come on, Edna!"

Cum on Edna.

"Wow, you were right, Bart," she said. "That does feel really good, doesn't it?"

"Yeah, it feels great! Now say it again like you mean it."

"Come on, Edna!"

Cum on Edna.

"Louder," Bart requested, fapping now at full speed, almost rocking his desk with his hand movements.

Mrs. Krabappel took a deep breath.

"Come on, Edna!" she exclaimed passionately, causing her enormous breasts jiggle like tidal waves.

Cum on Edna.

She's telling me to cum on her. My teacher is showing off her tits while telling me to cum on her body. What a horny slut!

"Ahh, take it, Mrs. Krabappel!" Bart moaned as his cock started shooting a stream of thick semen inside the sock.

"Take what?" Edna asked, tilting her head. But Bart couldn't hear her because he was still cumming while hypnotized by her magnificent chest.

"What am I supposed to take, Bart?" Edna repeated the question.

Oh crap, I really thought we were on the same page there. I shouldn't have said that aloud.

"Umm, take your own advice. 'Come on, Edna.' 'You can do it.' That stuff."

"Oh, I see. Thanks Bart." She giggled, finally turning around and walking back to the podium. "There's still fifteen minutes of detention left, but I think I'll let you off early since we seemed to come to an understanding about our teacher-student relationship."

Wait. Does she know after all? Is she just pretending to be oblivious. Well, either way I got lucky in more ways than one.

"Wow, thanks, Mrs. Krabappel. I'm really happy we were able to see eye to eye."

"Me too, Bart. Me too."
