Sister's Anatomy Lesson Chapter 2

***********************************************************************************************************************************

Alex makes his way down the stairs, shaking his head in irritation. How is he even going to help with the class? His mind wanders. His mom isn't going to make him talk to his little sister about puberty and stuff, is she? Wouldn't having a boy to help her learn female stuff just make things worse? He'd never admit it, but he didn't exactly know much at all about female anatomy...

He shudders at the thought, wiping the frown off his face and mustering his best *this doesn't bother me at all* expression.

"Uhh.. Yeah ma, what'd you need?" Alex asks, seeing his mother waiting at the kitchen table, a 12 year old Maggie sticking her tongue out at him while her back was turned.

Alex couldn't resist glaring back, the smug little shit. He combs his hand through his hair and approaches the pair. is mother greets him with a kiss to the temple. She had to bend a bit, and she ran a hand through his soft hair.

"MOM!" Alex moans, quickly using the sleeve of his hoodie to wipe the offending gesture from his face. His mother is unphased as always, chuckling quietly at his reaction as she takes a seat at the table.

"Have a seat hun," she says, gesturing to the empty spot next to Maggie. Alex shoots one last glare Maggie's way before taking a seat, slumping his shoulders forward and propping his chin up in the palm of his hand, clearly displeased.

"What is it mom?" He asks, not trying and failing to mask his aggravation.

His mother clears her throat. "Sorry for pulling you out of your little game Alex, I'll try and make this quick." His mother laces her fingers and looks him square in the eyes. "Maggie needs some extra help in her anatomy classes. She's really struggling with the diagrams and descriptions, and your father and I are starting to worry about her grades."

"Uh sure. Ok. I struggled with that too. I don't have the time to worry about doing my homework and Maggie's." Alex bluntly offers, shrugging slightly. There. That should be good enough, he thinks. Maggie can suffer a bit in school too for all he cares.

His mom smirks, as if she was able to read his thoughts. "Don't worry Alex, that's not happening. You don't have to do anything at all. I'll be teaching her everything that she needs to know."

Alex frowns, cocking his head incredulously. "So then why am I even-"

"I'll be teaching her," She repeats, "and you're going to be the model."

Alex can't believe it, and it shows on his face as it curls into a disgusted expression. "I... What?? No! Are you serious??"

Maggie snickers, clearly enjoying her brother's plight as their mom holds up a single hand to silence Alex. "No complaining; It's either that or no computer and tv until you're in college. Frankly that would do you some good, we might finally see your grades improve. So? Which will it be? Do you want to spend the next 4 years off the grid, or will you help your sister just once and earn your unlimited privileges?"

"That's insane! You can't do that! My grades aren't THAT bad, and I'm not going to-"

"A 2.3 GPA is more than bad, Alex," His mother retorts, a single eyebrow raised at his choice in objection. "and honestly your father and I are being more than generous by only making you help Maggie once."

"DAD agreed to this???" Alex shouts, the look of anger and disgust on his face giving momentarily to surprise.This is bullshit. What had he done to deserve this?

He stews in his anger, his thoughts racing. In the corner of his eye, he sees Maggie, with that same shit-eating grin. She giggles as they make eye contact, clearly enjoying this awful moment more than anyone else.

"No." He spits out, crossing his arms defiantly and leaning back into his chair. "I am NOT letting Maggie see my dick. You can't make me." As if to rub it in, that same lock of hair once again falls into his vision. 'Here, let me make things worse!' he can practically hear the world taunt.

His mother is unfazed, shifting in her chair to get more comfortable. Her mouth settles into a slight smirk, calling his bluff. "Fine." She extends her hand, palm up expectantly. "Phone." She demands simply.

Alex's mouth falls open slightly, his face starting to feel flushed and his cheeks burning as he realizes he's losing the argument. The unfairness of this situation is catching up with him. He'd actually doubted whether or not was serious about taking everything away for so long.

Across the kitchen table, Maggie is doing everything that she can to not openly laugh. Alex's face was priceless, his eyes wide and his mouth opening and shutting like some kind of fish.

"Alex." His mom repeats, snapping him out of the beginnings of a sulk. Her arm is out, hand open, demanding the immediate surrender of the phone.

He stares at his mother in silence for a few moments longer, his mind racing to come up with a solution. "I... You can't.... I'm not gonna..." Alex babbles, any attempt at forming a proper response instantly falling apart as it leaves his mouth. His mother's firm eyes continue to stare into his--her right eyebrow raising expectantly.

"F... Fine..." Alex mutters, his attempt at a frown faltering at his mother's successful intimidation tactic., ".... Once. This happens ONCE." He glances in his mother's direction, his anger quickly deflating. He folds his hands together, feeling more defeated than anyone in his karate class has ever made him feel.

He didn't realize his eyes had sunk into an angry pout aimed at his little sister until his mom's hand gently lands on his shoulder. "Oh stop sulking." She demands. "Helping your sister for a change isn't the worst thing that's ever happened to you." She pats his arm sympathetically, not wanting to see the boy tormented, but resolute that this was happening.

Alex sighs and slumps deeper into his chair.

"This fucking blows....." he mumbles to himself, looking everywhere but back at his little sister and mom. His hands rest atop his crotch defensively, already feeling exposed. He sits quietly, taking in a deep sigh and resigning himself to his new fate.

"We won't take long, alright sweetie? Then you can go back to your little game." Alex's mother reassures, standing from the table, while Maggie quickly follows suit. "Come on." She coaxes the boy to stand.

"W-what right here???"

Author's Note:

Wowie, thanks for the positive replies guys! I've never written any stories like this except for myself, so I didn't really expect much at all! Lemme know what y'all think, and feel free to make suggestions whenever

As for suggestions:

Alex stands and strips right there in the kitchen, since that is where Maggie has her homework out.

He does his best to ignore things, but being a young teen with raging hormones, the inevitable happens.

Using Alex an example, Maggie gets a further education about boys’ penis and erections (specifically, Alex’s)

Perhaps Maggie feels the need to get ‘hands on’ experience

So good! Written really well. Can't wait for more

Sister's Anatomy Lesson Chapter 3

***********************************************************************************************************************************

"What right here???" Alex asks, panic once again seeping into his voice. It just felt so much wronger in the kitchen. Plus! They were on the ground floor and there were windows?

"Well where else are we supposed to go?" His mother asks, chuckling a bit at her son's stalling. "Maggie's room?"

God no," he groans, a blush returning to his face. Somehow, that would make this feel even worse. "Not her room. We're not doing this her room. We can use your room, or the bathroom, or-"

"No. She is NOT going in my room." He protests, the words coming out slow and deliberate. He is doing his best to maintain his composure.

"Awww, but you never let me in your room. It would be so much funnier if I got to see you nakie in-"

"Oh shut up Maggot." Alex spits, growing increasingly displeased with just how much his sister seemed to be enjoying the prospect of humiliating her brother. He only realized just how much he had screwed up after his favorite 'nickname' for his sister left his mouth.

His mother's gaze shifted from her daughter to her son, the anger evident in her eyes. Alex immediately looked down, a sheepish expression creeping back onto his face.

"Alex Bowe," she demands, her voice calm and steady, but the way she dragged out each word made it clear that she was livid. "You are on extremely thin ice mister. You're going to go wherever your sister wants to do this, am I clear? If I so much as hear one more objection from you, this is NOT going to be the only time we do this. Now STRIP."

"But mom, I-"

"NOW Alex."

"Ok ok! I'm doing it!" he blurts, not wanting his punishment to be even worse. Whatever that would even look like at this point. With his two female family members watching him intently, he slips his sweatshirt and shirt over his head at once, exposing his pale torso and toned arms. No matter how many karate classes he attended--no matter how much he worked out--he never seemed to 'fill out.' Something that he felt more conscious about now than ever before.

His eyes darted towards Maggie, who's gaze was fixated on her older brother. The look on her face was unreadable. She wasn't laughing at him, or making fun of him, or smirking... Just staring at him, her mouth slightly agape. He was already embarrassed, but the fact that Maggie was just gawking at him was doing nothing to help.

His shaky fingers start to unbutton his jeans, the embarrassment of the situation quickly becoming overwhelming. He glances at his mother, still hoping that she would laugh, and tell him that she wasn't serious, or that he could stop there.

"All the way Alex." She says, the annoyance evident in her tone. "Your sister has a full night's worth of anatomy homework ahead of her, so if you want this to be done sooner rather than later, the faster you finish, the better."

He nods slowly, biting his bottom lip. The last thing he wanted was for this to drag on. With a few quick motions, his jeans were off, pooled around his ankles.

"Ohhhh, do all boys wear pretty underwear??" Maggie quips, pointing at the pair of dark purple boxer briefs her brother had on. She was unable to contain herself any longer, bursting out in a fit of laughter. Alex's face was bright red. He always dressed a bit metrosexually, a perfect match to the boy wearing them--he tweezed his eyebrows, always dressed nicely and put a lot of time into his hair--and he'd never been embarrassed by that until now.

He generally liked it when a girl his age called him a pretty boy. But his sister...?

"They're not pretty..." He mutters under his breath.

"They are tooo!" Maggie teases, sticking out her tongue as she slinks closer.

"They're not!!! Shut UP!!!"

"Alright, alright, both of you. That's enough. Alex, this is new to her, she's just teasing. And Maggie, don't antagonize, you're only going to make this harder..." She sighs, her gaze falling upon the boy, who was still standing with his jeans at his ankles. "I thought I told you to strip completely Alex." She remarks.

"Can we not do this here? Please?" Alex asks, the desperation creeping into his voice. In the corner of his eye, he catches a passerby walking along the sidewalk. The man doesn't seem to notice what's going on through the window, but the boy shuddered at the thought of how easily someone could see him like this. "I'll do anywhere else."

"It's okay mommy, we can have him lay on my bed if it would be easier for him."

"Ughh, no, that's worse!" Alex whines. Being naked is one thing, but laying naked on his little sister's pink bead spread, next to her dumb collection of plushies?

"Alex at this point it's here, there, or in the backyard." His mother warns. "Pick one. I'm done arguing."

"But- ok fine, we can go into Maggie's room. Whatever." Alex grumbles, the humiliation continuing to pile on. He takes a step out of his jeans and awkwardly shuffles away, his sister skipping ahead and leading the way to her room. The cool air might have felt almost good on his lanky legs, if not for that feeling of impending doom.

The three of them enter the room, Alex's eyes glancing around and his heart sinking. The place is exactly what you would expect of a younger sister. There are stuffed animals lining every flat surface. There are posters hanging on the wall of her favorite pop groups, and pictures she'd taken with her friends.

Alex sighs, the reality of his situation setting in. This was going to happen, and there wasn't a damn thing he could do about it.

"Hurry up and get on the bed, Alex. We have a lot to go over."

Alex nods, the last of his resolve drained from him. He climbs onto his sister's bed, and lays on his back, his body rigid. His mom sits on the edge of the bed, and gives him an empathetic smile. She places a gentle hand on his chest and pats softly, making him jump.

Maggie climbs up and slides just below him, laying on her stomach and propping up her head on her arms. Her face frozen in a look of excitement and anticipation.

"Well, alright. So first we'll start with the basics..." Alex's mother begins. "... the underarms and chest When boys hit a certain age, they start to grow hair in new-"

"Mooooom. I already know that. When do we get to see his wiener?"

"Maggie! We're doing things the right way. We have to cover the basics." Their mother says, pinching her brow. "Honestly, I certainly didn't raise you to be so brash..."

"Booooooo...." Maggie pouts, looking up at her brother. "But Alex said he wanted this to be fast, and this is the part I don't get! So we should just start with his thingy." She taunts.

Alex's mom sighs and rubs her forehead. "Alright, fine, since you're already familiar with the basic structures, I suppose we can just move on. Alex, do you mind?"

"Do I have a choice?" He responds dryly.

"Not really, no."

"Alright then. Maggie, go ahead and pull your brother's underwear down. Let's just get this over with."

"W- wait mom! Can't I just do it?" Alex pleads, hoping for at least a shred of dignity.

"Alex, your sister is becoming a woman. Don't you want her to feel comfortable around boys when the time comes?"

Alex groans and covers his eyes with his hands, not wanting to watch. "This isn't the same thing at all..."

"It is, and it's good practice for her. Let her have her fun."

Maggie squeals with delight and claps her hands. Alex feels the bed shift as Maggie gets closer a bit more comfortable. He hears his sister suck in a deep breath, and the next thing he knows, his sister's little fingers are tugging his boxers down his hips.

His body jolt at the unexpected contact, his voice cracking slightly. "H-hey, warn me first!"

The boy's dick flops free from the confines of his underwear. It's mostly soft, and falls back between his legs, lolling slightly to the right. Maggie gasps.
"Woah, it's so much smaller than the diagrams." She says, clearly amused. Alex's face turns a deep shade of red in response, but he's too overwhelmed to even form a reply.

"Well..." His mother begins, tilting her head to get a better view. "It's maybe a bit smaller than average, but your diagrams are of the adult body. You brother is still a growing boy." She offers with a smile.

Alex only groans in response, covering his eyes once more, in hopes that his surroundings will simply fade away--like a dream. Or a nightmare really.
But nothing of the sort saves him. The bed shifts once more, and he feels little puffs of hot air on his privates. He tries to scoot back slightly to avoid the tickly breath, offering a weak "Y-you don't have to get so close..."

"Let her get a closer look hun, she's not hurting you."

He doesn't offer any further complaint. He couldn't possibly feel any more humiliated than he already was. So he just lets his sister look. She's silent, and Alex is too afraid to uncover his eyes and look down. What is she even doing? Is she just staring at him?

When his answer comes, it's even worse than he could have hoped for.

Love it!
So glad for a new regularly updated story
And it’s a strong one too

[TeenFan]

The mom wanted to begin the lesson with examples of where hair tends to grow on a boy's body as puberty sets in.
There can be a full description of what Maggie is looking at, sparing no details and beginning with the pubic hair.

Considering this is the writer's first story here, I am impressed.
Great work, SeeEffenem.

[Lola]

I absolutely love how the place makes him even more embarrassed! Brilliant. You're a great writer!
