Sister's Anatomy Lesson Chapter 8

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

“But mommy, whose going to bring me to Girl Scouts then?”

"Oh Maggie, I thought your troupe moved meetings to Tuesdays!" Their mother asks, huffing softly and crossing her arms.

"No mommy, that's not until next month!"

Their mother looks contemplative for a moment, her foot tapping against the hardwood floor and her finger rubbing her chin. "Alex can drive you! I'm sure he'd love the opportunity to put his learner's permit to use."

"I would?” Alex interjects sarcastically, a look of aggravation crossing his features. Sure he would have any other time when he wasn't like this!

"Yea, you would." His mother states, her expression blank, daring him to object.

"I really should just go back to my game though..."

"It will be here when you get back." His mother says. Her agitation drops momentarily as she lets out a soft chuckle at her son's antics. Boys and their toys... "Besides, if you get more practice now, you'll be able to get your actual license sooner. Then, you'll be able to drive people that aren't immediate family members."

"Fine.."

"Thank you Alex! Thank you Mommy!" Maggie exclaims from upstairs, a slight skip in her step.

"Oh, and Alex, put on a pair of pants before you leave. I don’t want you having ANY reason to be pulled over when all you have is a learner’s permit."

"Yes mom." He smirks to himself. Bingo. His mother just gave him a get out of jail free card, and there was nothing Maggie could do about it! Still, there was no telling what kind of shenanigans Maggie has left up here sleeve. She still had the ability to blackmail him on command...


"Don’t worry Alex - I'll get you some pants if you start the car?” Maggie offers with a sweet smile.

“No, stay out of my room!” He demands, grumbling. Was he allowed to have anything private anymore?

“Ohhhhh ok. Don’t worry, I can grab something from the laundry then!” She giggles, walking across the hall and opening the door.

The boy follows her, his shoulders slumped, and his eyes focused on the ground. His cock continues to wave from side to side as he makes his way around the house, as if it was announcing his presence. He doesn't look up, not even as he hears her rummaging through the clean laundry.

"Here! These are YOUR gym shorts, right?"

"Yeah..."

"Ok! You can wear these then!”

She tosses the pair of black athletic shorts over to him, which land in his face. Alex is too defeated to protest, so he simply grabs them and pulls them off his face, his expression blank. That is, until he notices which pair she'd selected.

"Maggie I can't wear these."

"Why not?"

"Because I don’t even have anything to wear underneath them, and they’re like... almost see through. Grab me some briefs or something.”

"So? do you not want people seeing your peener?"

"YES. No shit Sherlock." Alex snorts.

"Well I don't know! I don't have one, I'm a girl! Maybe just keep your hands in front, and it will be fine." Maggie retorts with a tone that makes it out like ALEX was the one who had said something ridiculous.

"That doesn't help at all! What if I have to stop and someone looks over? I have to keep my hands on the wheel!”

"Well then just be a good boy and don’t get pulled over. You weren't going to speed were you?" She grins and gives a dramatic shrug, her eyes locking onto his cock as he slides on the shorts.

Alex's breath hitches as the cool fabric slips over his cock. The thin material does nothing to hide his raging erection, which is pushing at the seam, creating an outline of his entire length, and the swell of his swollen glans. He shudders, and closes his eyes. They do so little to cover him, that he might at well be naked!

"This is so fucked Maggie..."

"Ohh! Your thingy looks s so big and jumpy in those!"

Alex's eyes snap open. His sister is right there by his side. Her hands sneak around to his waist, mustering her strength to make his hips sway slightly. His larget stature makes it hard for her to do little more than make him rock an inch or less.

Alex makes her a bewildered expression. "What... What the fuck are you doing now???"

"Watching your thingy bounce. I can really see the shape of your peepee when you move around!”

"MAGGIE."

But good lord she was right. Alex's face paled in horror as he watched his erection bob from side to side as Maggie shook him. These shorts were worse than just kind of see through--the material wasn't strong enough to flatten his erection at all. Every little moment just caused them to ride up, and being even MORE revealing and form fitting,

"Maggie! Maggie PLEASE!" He begged like a man whose life was being threatened. He debated falling down onto his knees. "Please don't make me wear these! I'll do anything else! Please!"

"Alex, they're fineeeee." She groans, rolling her eyes. "Who would want to stare at a boy's big ugly peepee anyways. Let's just gooooo."

Alex can only whimper in response, turning away from his sister and making his way out of the laundry room, his head down, and his face burning red. This was it. Maggie was trying to ruin his life.

***

The two siblings drive in relative silence, the only sounds being the soft hum of the radio, and the occasional snickering coming from Maggie. The two hadn't exchanged more than a few words since they left the house, the most being his sister's occasional snort and giggle at the sight of her brother's shorts, which had remained tented the entire trip.

Alex's hands gripped the wheel tightly, his knuckles turning white. Every once in a while, a car would pass, and his sister would let out an excited squeak, watching the car pass.

"Do you think they saw???" But it was less of a question, and more of a hope in the form of a question.

"Probably not, it’s pretty dark out…” Alex reasoned--equally with himself.

"Yeah, but your peener is so big, it's hard to miss!"

"Maggie..."

"What? It's true! Your peepee is bigger than any of my fiends’ little brothers!”

"Please stop talking about dicks…” Alex moans. In truth, thinking about his sister treating other boys this way made him feel... funny. But after the day's events so far, he'd never be think about their sibling dynamic the same again.

"You know, I was going to wait till we got home..." Maggie pauses, her hand slipping over the armrest. Her tiny hand slides onto his thigh, her fingers pressing into his flesh.

"Maggie. What are you doing." Alex asks, his voice tense, trying (failing) to control his composure while he's behind the wheel.

"Shhh, you'll like it."

"Maggie, don't touch me… I’m driving. Please."

"But playing with you is fuuuuun.” She giggles as he hand slips underneath the leg of his shorts.

"MAGGIE NO."

"Why not? It seems like you want to be played with!" Alex gasps as his sister's fingers brush against his shaft, his hands tightening their grip.

"S-stop that, we're almost there anyways.” He grumbled. Despite his objections, the boy’s legs widen, subconsciously giving his younger sister easier access to his cock.

"See? You like it!" Maggie giggles, as her fingers slip further into the leg of his shorts, finding the base of his cock. Her fingertips gently graze the sensitive skin, sending a shiver up the young man's spine.

"We're going to get in a wreck if you keep this up..."

"No! Just keep looking at the road. Besides, aren't you having fun?"

Alex swallows hard. A small part of him is telling him to push her away, that he needs to stop her. But that part is being drowned out by the part of his mind screaming to let her continue. His cock was painfully hard, his balls aching with every beat of his heart, and his skin felt like it was on fire.

“Lift your butt up.” Maggie demands as the car comes to a stop at an intersection.

"C’mon Maggie why?" Just leave me be!”

"So I can take your shorts off silly. Come on! We're almost there."

Alex can't think straight. His mind is screaming to fight, but his body is moving on its own. “I know WHY. I Just mean… Why?” Alex grumbles, quickly losing his words as his arousal takes over.

He looks anxiously around for any other cars, before gently lifting his hips, allowing the little girl to tug down his shorts. His cock springs free, slapping his stomach, the tip glistening with a bead of pre.

"Wow! It's so needy looking Alex!"

"M-maggie, wy do you always have to be such a… such a-OOOooooh"

"There. That wasn't so hard!” Maggie exclaims, her tiny fist wrapping around her brother's aching erection.

"That's easy for you to say... You're not the one being felt up..." Alex moans. His eyes strain to keep open, his hips bucking slightly.

"Awww, it likes me!" Maggie teases.

"N-no shit. Now just keep your hands to yourself, ok?"

"No." Maggie says plainly.

Alex's face twists with conflicted feelings, his hands gripping the steering wheel. He knows he shouldn't let her do this. But his mind is screaming at him, begging him to just give in, and let her continue. His cock is throbbing in her hand, and the warm tingling sensation is spreading through his body.
"This next turn here. Awe… we’re almost there.” Maggie pouts, her hand gently stroking the underside of her brother's length, making him shudder.

"Yeah..." Alex moans, his head lulling back slightly. His hips roll forwards, thrusting his cock into her tiny fist.

"Do you want me to stop?" Maggie asks, a grin forming on her lips.

"N-no. Yes? Fuck... I-I don't know..."

"Ohhh! Maybe we can pull over!" Maggie giggles deviantly.

"N-no Maggie, we can't. There are so many other cars here" Alex mumbles. His words were starting to slur together, his body melting into the sensation of his sister's tiny hand wrapped around his pulsating erection.

"I’m kidding! Don't be such a perv! I would be late for scouts!”

"Right, late." Alex murmurs, his eyes fighting hard to remain open.

"Are you listening to me?" Maggie giggles, her hand giving his cock a playful squeeze, making his whole body jerk.

"Huh? Y-yes, we can't. Let's not be late."

"Mmmhmmm." Maggie giggles at how easily she was able to melt her brother's brain when she played with him.

His hips are rocking now, his cock sliding in and out of his little sister's fist. He's almost at the end of his rope, the pressure building in his shaft reaching its peak.

"God Maggie, we're going to get in a wreck if you keep this up..."

"Pull in here."

"Huh? Oh, yeah. Sorry"

Alex pulls into the lot, his hands trembling slightly. His sister's hand is still wrapped around his shaft, her palm cupping his swollen tip. He's panting softly, his cheeks flushed and his body hot.

"We're here! Come on Alex" Maggie giggles, her fist squeezing his cock tightly. Let's go, the others are waiting!" Maggie giggles, her hand suddenly vanishing.

"Wait, Maggie-"

"Come on, I can't be late! What would the scoutmasters think?" Maggie taunts.

"They'll probably ask what the fuck happened to my pants." Alex retorts, his brain snapping back to reality. He looks down, his breath hitching.

“Well put your shorts on silly, and we'll be fine."

"Oh, right."

Alex leans down, reaching under his seat, grabbing his shorts and pulling them up his thighs. His cock disappears into the fabric, but the outline is still clearly visible, along with a small wet spot at the tip.

"Ok. See? No one can tell!"

"Yeah sure. Whatever you say..." Alex sighs, opening the door and stepping out. The moment his leg swings out, taking his first step, the tip of his cock pushes past the leg of his shorts—sticking out lewdly.

"Shit..."

"Hahahaha, your peepee is trying to stay out and play!" Maggie cackles, hopping out of the car and walking over.

"It’s NOT funny. I can’t go in like this!”

"It's kinda cute though" Maggie teases, her fingers grazing his exposed head.

"Knock it off, I’m serious. What am I supposed to do?” Alex mumbles, his body going rigid. His legs are trembling, and his mind is racing.

Keeping his engorged glans in her fingers, Maggie simply begins walking. Her grip is firm but delicate, and Alex is obliged to follow for fear of her tugging. "Nothing. None of the parents stay this late. You'll be fine."

"But Maggie!" Alex whimpers, stumbling after her.

Maggie offers no response, electing instead to begin gently pinching and stroking the boy's glans, repeatedly tweaking the tip of his member.

"M-maggie, s-top."

"Make me. You don't want me to get you in more trouble do you? Besides, it's fun!" Maggie retorts, as she guides the two towards the door.

"F-fun for who? Maggie. This isn't fun for me! It's humiliating!!" Alex pants, his hips twitching.

"Me! For me!" Maggie giggles, reaching for the door with her free hand. "Alright. Let's go inside!"

"WHAT?"

"We're here. Now come on. At LEAST walk me into the main hall." Maggie says, her hand grabbing the handle.

"And... And there's no one in the hall right now?" Alex asks, his heart pounding.

"Nope! Even I'm not that mean. Promise!"

"O-okay... If you're serious..." Alex stammers, his voice cracking.

"I swear!"

Maggie opens the door, stepping through, and dragging her brother along with her.




Holy. Shit.




HOLY SHIT HOLY SHIT HOLY SHIT!

There were SO many girls in here!!!! Maggie had led him directly into the midst of a meeting!

Alex's eyes widened, his whole body trembling. The hall was filled with girls of all ages. He felt a rush of embarrassment, and panic, his heart hammering in his ears.

"Heyyyyy, we're hereeee! And I brought my big bro like I promised!" Maggie exclaims, gripping his cock harder like a leash, and waving her free hand.

"HIIIIIIII MAGGIEEEEEEEE!" The chorus of girls erupts in unison!

*To be continued...*

Love the turn of events in this story! Little sister is definitely in control and he has to do what she says. Hopefully her girl scout friends and other girls will get in on the action soon too.

You're welcome Jeepman

[Jeepman89]

Holy Shit is right! That was an amazing chapter and that scene in the car is outstanding. And what a cliff hanger, walking in to the meeting with all those girls with Maggie holding his cock! Outstanding!

[NudeBaG]

Fun fun fun

[Black-Fox]

Thanks.

[Trundle]

Oh I thought i'd already left a post on the latest chapter but it seems to have disappeared. Strange

Anyway of course I loved the latest update, it was fantastically written as always. I assumed that Maggie would maybe expose Alex to one friend, maybe a small group of girls but not the entire scout troop. Now Alex really is trapped, can't wait to see what they have planned. I have a feeling he may end up losing the flimsy underwear, and possibly his t shirt too.

And what if he's caught by an adult ? Very high stakes. Cannot wait for more

[Jeepman89]

I wanted to ask if he was wearing a shirt since it wasn't clear in the last chapter.

[Trundle]

I think he has a top on unless I'm mistaken?

I could definitely see Maggie wanting to get Alex completely naked though, not even giving him a t shirt to cover up with

[Jeepman89]

Yes, he needs to be seen by the girl scouts totally bare ass naked.

[SeeEffenem]

I think he has a top on unless I'm mistaken?

I could definitely see Maggie wanting to get Alex completely naked though, not even giving him a t shirt to cover up with

Hmmmm. Unless I've lost track of some parts of my own story at this point, he hasn't had a shirt on since chapter 3! Maggie only gave him a pair of shorts! Now you guys have me second guessing, did I give him a shirt at some point since then? lol
