The morning drags on like pure torture. We are only sharing one class today: gym. And it’s right before lunch. Every minute feels endless. My mind keeps replaying Marie-Rose’s breathy moans from last night, the way her soaked panties clung to her pussy, and that wicked little giggle before she hung up. By the time gym class finally arrives, I’m already half-hard.

After making my way into the men’s change room, I head right to the bathroom. Even though we’re all guys, I don’t like drawing attention to myself. I change into my gym shorts and t-shirt fast, heart hammering, then head out to the field. And I already feel sweat beading on my forehead. It’s another humid day! I do a quick scan of the school grounds. And a few minutes later, I see her and breathe a sigh of relief.

I spot Marie-Rose standing awkwardly near a group of girls in her tight t-shirt and tiny athletic shorts. Her brown hair is pulled back in a messy ponytail, a few strands stuck to her flushed cheeks. A faint shine of sweat glistens on her collarbone.

My gaze drops to her chest. The thin t-shirt clings to the modest swell of her breasts, her shape clearly visible. My cock twitches, straining against my gym shorts. I wonder if she’s wearing a sports bra underneath, but from this distance it’s hard to tell.

She catches my eye and gives me that same innocent-yet-knowing smile she gave me yesterday. Marie-Rose then gives me a shy wave. My breath catches in my throat, and I feel a warmth spread in my chest. Is she aware of the kind of effect she’s having on me right now? She has to know how unfamiliar I am with attention from girls, right?

A sweet drawl inches away from my face suddenly breaks me out of my trance. “Earth to Nolan! I’ve called you five times already!” Marie-Rose playfully slaps my arm. “Not to mention, I’m standing right here in front of you.” She giggles. I rub the back of my neck, muttering an apology with a sheepish smile. And she gives me a sweet smile, emphasizing that she’s amused rather than annoyed.

We walk towards the track together. Marie-Rose bumps her shoulder lightly against mine. “You were staring at me… at them, weren’t you?” she teases under her breath, her voice low enough that only I can hear. Her cheeks are already pink from the heat.

“I wasn’t…” I start, but she cuts me off with a soft laugh.

“It’s okay. I don’t mind.” She glances sideways at me, that same knowing little smile playing on her lips. “Especially after yesterday.” For a second, her fingers brush against the back of my hand as we walk. The brief contact sends electricity up my arm.

Suddenly we hear the blow of a whistle, making us both jump. And the commanding voice of our gym teacher. “Ok, I want ten laps around the track! No ifs, and, or buts, or I’ll have your butts for breakfast! Go!”

My stomach does flips the rest of the day. But finally the final bell rings for the day. And I head right to the same hallway spot where Marie-Rose and I walked home from yesterday.  Since we only shared gym class together today, I am anxious to see and talk to her again. Plus, the sight of her in that modest sports bra and shorts drives me crazy!

As I stand there waiting, I can’t help but smile like an idiot. And remember her catching me staring more than once during gym, and each time she gave me that tiny, knowing smile that makes my shorts feel way too tight. I can’t help it! Even when girls wear sports bras, their breasts still move around! I glance nervously at my phone again, wondering what’s keeping her. She must be late leaving her class. I hope she’s okay.

The minutes drag by until the hallway gradually empties out, and only silence remains. Just when I’m starting to worry, Marie-Rose finally appears a few minutes later, her face still a little flushed from gym class. She’s changed back into her modest long skirt and blouse, looking every bit the perfect preacher’s daughter again. But her shoulders are slumped, and she looks tired.

“Hi… everything alright?” I look at her with concern.

Marie-Rose sighs and leans against the lockers beside me. “Hey… am I glad to see you. Today was… not great.”

“What happened?” I ask.

Marie-Rose glances around to make sure no one is listening, then leans in, her voice barely a whisper. “In the locker room… some of the girls saw me changing. They made fun of my ‘grandma bra and panties.’ Called them ‘Sunday school undies.’” Her cheeks burn deep pink and her shoulders shudder at the memory. “They laughed about how I dress so formally. I know it’s stupid, but… it really hurts. I already feel like the weird new girl who doesn’t belong here.”

The sadness in her voice hits me harder than I expected. She suddenly looks smaller and more fragile, nothing like the confident girl who’d teased me on the phone. I hate that anyone made her feel this way. The thought strikes me: maybe I’m the only one she lets see that bolder side of her.

That explains why Marie-Rose was standing by awkwardly before. And she’s been holding onto that feeling ever since. I’m used to guys being idiots in the locker room, but hearing about girl drama is completely new territory for me.

“That sucks,” I say softly, fighting the urge to pull her into a hug right there in the hallway. “People can be assholes for no reason. You looked… really good in gym class. More than good.” My face burns as soon as the words leave my mouth. “I-I mean your bra looked fine. Not that I was staring or anything!”

Smooth, Nolan.

Marie-Rose stays quiet for a moment, staring at her shoes. Then she slowly lifts her gaze. The sadness in her big brown eyes shifts into something warmer… something dangerous. A sly little grin tugs at the corner of her lips.

“Is that so?” she murmurs, her voice dropping into that sweet, honeyed drawl again. “Maybe you can help me pick out some sexier ones this weekend. So I don’t look like such a little church girl anymore.”

My brain short-circuits. “Whoa, hold on… ”

She giggles at my panic, clearly enjoying it, and steps closer until I can smell her shampoo. “You seemed to like my plain white cotton ones just fine yesterday,” she teases. “I thought you’d have good opinions on what would look nice… on me.” Her eyes sparkle. “Or are you just scared of getting caught in the fitting room with me?”

The image of Marie-Rose in a dressing room, modelling tiny, lacy things for me while trying to stay quiet, hits me like a truck. And my cock strains painfully against my boxers.

It’s now the weekend, and I’m driving my parents’ sedan. My heart is practically beating out of my chest. I don’t know how Marie-Rose was able to convince me, or why I agreed to it, but I’m accompanying a classmate on a shopping trip today. For lingerie, no less. I smile to myself. In a way this is kind of funny. I recently got my driver’s license, and one of the first things I do with it is take a girl shopping for underwear.

I tell myself it’s because I’m simply bored and need to leave the house. But, after getting over the initial shock, it’s admittedly really because I want to see the sweet and sheltered girl beside me trying on underwear.

I pulled into the parking lot and put my parents’ car in park. After shutting off the car, I hear Marie-Rose’s short, shaky breaths cutting through the silence. But it’s unclear if she’s anxious or excited. I awkwardly clear my throat before looking over. She’s wearing a casual yellow t-shirt and black miniskirt with grey leggings today. “You know… we don’t have to do this. Those girls don’t know anything, so you don’t have to impress them.”

Marie-Rose looks at me with her big brown eyes. And gives me an appreciative smile. “I know… it’s just not fun being the new girl in class.” Suddenly, her smile turns devilish. “But honestly? This is mostly for your benefit. You’ve been such a good sport about yesterday.” She bites her lip, then reaches down and slowly lifts the hem of her miniskirt. “Here… let me give you a little taste.”

My heart hammers. Is she crazy? I glance around the parking lot nervously, but no one is paying attention. When I look back, Marie-Rose has not only raised her miniskirt but slid her grey leggings down her thighs. She’s flashing me right here in the car. The pale pink panties with tiny red cherries look incredibly cute on her. Sweet and innocent, yet the way the thin fabric clings to the soft mound of her pussy makes my mouth go dry.

My heart pounds so hard I’m sure she can hear it. I glance frantically around the parking lot, terrified someone might walk by and see us. A couple of people are heading into other stores, but no one is looking our way. Still, the risk makes my cock throb painfully against my shorts.

“Marie-Rose,” I whisper, voice strained. “What if someone sees?”

She giggles softly, clearly enjoying my panic. Instead of pulling her skirt down, she spreads her legs a little wider on the passenger seat, giving me a better view. “Then they’ll see how wet I’m getting just from showing you,” she teases in that sweet drawl. Her cheeks are flushed, but her eyes are sparkling with mischief. “Do you like them? I wore these ones on purpose… because they’re still cute, but I thought you might like the little cherries.”

I can’t stop staring. The damp spot on the front of her panties is unmistakable. “Fuck… yes. They’re perfect,” I manage, my voice rough. My hands itch to reach over and touch her, but I grip the steering wheel instead, trying to stay in control.

With a playful little wink, she finally pulls her leggings back up and smooths her miniskirt down. But the teasing isn’t over. As I try to adjust myself so I can actually walk, she leans over, her breath warm against my ear.

“Poor Nolan,” she coos. “All hard and aching again. Maybe if you’re good while we shop, I’ll let you pick which pair I wear… just for you.”

I sigh heavily before undoing my seatbelt. My face feels like it’s on fire as we step out into the warm afternoon air. Marie-Rose slips her hand into mine like it’s the most natural thing in the world as we walk toward the boutique entrance.

The lingerie boutique feels dangerously intimate. And girly. My pulse is already racing as Marie-Rose keeps her fingers in mine, pulling me toward the back racks like she’s afraid I might bolt. Is this my brain giving me not-too-subtle warning signs that I don’t belong here?

She bites her lip as she browses, occasionally holding up a piece against her body and glancing at me for approval. A sheer baby-blue bra and matching panty. A red cotton brief. A lacy black bralette and matching panty that look too adult for her. Every time she asks “What do you think?” in that sweet voice, my cock throbs harder in my shorts.

My heart beats rapidly in my chest. “Yeah… they’re cute. Definitely different from what you’ve been wearing.”

Marie-Rose smiles at me. “That’s the idea.”

Eventually, she gathers a few items and disappears into a fitting room. I stand outside like an idiot, pretending to look at my phone. Anything that won’t draw attention to myself. Then her soft voice calls through the curtain.

“Nolan… can you come here? Please?”

I slip inside and quickly pull the curtain shut behind me. The fitting room is small, forcing us close together. Marie-Rose stands in front of the mirror wearing the baby-blue bra and matching panties. The sheer fabric clings to her modest breasts, her stiff nipples clearly visible. The matching panties sit low on her hips, the thin material outlining the soft shape of her pussy.

“Do you like it?” she whispers, turning slowly so I can see her from every angle. Her cheeks are flushed dark pink.

I swallow hard. “You look… fucking incredible. And your… bra and panties are pretty.”

Real original, Nolan.

A shy but pleased smile spreads across her face. She steps closer until her body is inches from mine. “Thank you. I feel so naughty wearing this,” she admits, her voice barely above a whisper. “But I like how you’re looking at me.”

My hands start shaking. I feel my cock straining uncomfortably against my boxers. And I stand there, gazing at Marie-Rose’s cute body in her lingerie. It’s all I can do to not reach out and kiss her; right here in the fitting room.

Marie-Rose giggles as she notices my predicament. “Could you turn around? I’m going to change into these red panties now.”

My face burns with embarrassment, but I oblige. I hear the sound of feet shuffling, followed by a soft sound of fabric being stretched. My heart is practically beating out of my chest; knowing that Marie-Rose is changing her panties right behind me.

“You can turn around,” she chirps.

I turn slowly, half expecting her to be fully clothed again. Just to mess with me. Instead, Marie-Rose stands there in the red cotton briefs. They’re cut higher and snugger than her usual style, hugging her hips and ass perfectly. The bright red colour looks surprisingly bold against her pale skin, and the way the fabric cups her pussy makes my breath catch.

She does a little spin with a playful smile. “Better than my other ones?”

My throat dries up. “Y-yeah… red is definitely your colour. If you wear this on Valentine’s Day, and we happen to have gym that day, those girls won’t be calling your underwear boring anymore.” I immediately feel my cheeks burning. What a weird thing to say!

Marie-Rose laughs heartily. “Well, thank you for that glowing endorsement! I may just take you up on that.” She smiles sweetly at me. “And try to remember: This is for you. I’m trying these on for you.” She makes a turn-around motion with her finger. “Alright then, mister. Last set! Close your eyes.”

I obey, with my heart hammering. I hear the soft rustle of fabric as she changes again. The red briefs sliding down her legs. The image of her completely naked for a few seconds in this tiny fitting room is driving me crazy. Then I hear the sound of lace being stretched and adjusted.

“You can look now.”

When I open my eyes, the sight nearly knocks me over. Marie-Rose is wearing a black lace bralette and matching panties. The sheer black lace does almost nothing to hide her stiff pink nipples. And the delicate scalloped edge of the panties frames her pussy perfectly. Everything about this set screams.

I feel my penis leak pre-cum into my boxers. “Fuck…” I breathe, unable to stop staring. “Marie-Rose, you look… so grown up in that set.”

Marie-Rose playfully strikes a pose with her hands on her hips and giggles. “I think we found our winner!” Her face is full of confidence.

“So… um,” I start, my voice a little shaky. “After you check-out, do you want to come over… to my place for a bit? My parents are out for the afternoon, so it’s quiet. We could… hang out. Look at your new stuff again, maybe?”

Marie-Rose looks at me, her big brown eyes sparkling with that familiar mix of shyness and mischief. A slow smile spreads across her lips.

“I’d love to,” she says softly, squeezing my hand. “But let me get dressed first...”

After changing back into her yellow t-shirt and miniskirt, Marie-Rose and I leave the fitting room. And at the check-out, she insists on paying for everything.  The saleswoman gives us a knowing little smile, but Marie-Rose just beams innocently, swinging her shopping bag as we leave the store.

The drive back to my house is thick with tension. My heart is racing in anticipation. This is really going to happen; I’m going to have a girl alone to myself, in my house. And the moment we step inside my bedroom, Marie-Rose turns to me with a determined little expression.

“I’ve been thinking about this since yesterday,” she says softly. “You made me feel so good… but you didn’t get to finish. That’s not fair.”

She gently pushes me until I sit on the edge of the bed. My heart pounds away in my chest. “May I? I want to thank you properly,” she whispers. “For the shopping today… and for stopping yesterday before you could cum.” I nod my head. Despite my shock, I want this just as much as she does.

Then she kneels between my spread legs, her big brown eyes looking up at me with an intoxicating mix of nervousness and excitement. Her small hands tremble slightly as she opens my shorts. She then pulls down my boxers. My cock is already hard and leaking pre-cum.

“Marie-Rose…” I groan.

She wraps her hand around my shaft and starts stroking, exploring every vein and ridge with her gentle fingers. And then she touches the sensitive head, spreading the slick pre-cum around. I hiss through my teeth, as my hips jerk involuntarily.

“You’re so hard,” she murmurs in wonder, leaning in to softly kiss the shaft. Then her tongue comes out, licking from base to tip. She closes her warm, wet mouth around the head and gives a gentle suck.

She finds a steady rhythm, stroking me with one hand while her tongue swirls around the head. Her eyes stay locked on mine the whole time, watching every reaction, learning what makes me groan and twitch. The sight of sweet, innocent Marie-Rose with my cock in her mouth is almost too much.

My eyes begin fluttering, and I moan with pleasure. “O-oh god… how do you know h-how to give blowjobs, but not… w-what ‘doing it’ involves?” My voice breaks as Marie-Rose brings me closer to the edge.

She moves away from my mouth. And with a giggle, she says, “Same reason why you may know how to park a car, but not how to build one.” I feel my face burn. She has a point.

And with that, she resumes stroking me. Her strokes grow more confident. She squeezes a little tighter, twisting her wrist exactly how I like it. “I want to feel you come,” she breathes, pulling back just enough to speak. “Please, Nolan. Come for me.”

The combination of her soft voice and her eager little hand sends me over the edge. I groan her name as pleasure crashes through me.

“Holy shit!…” I manage to croak before I hit my climax.

Thick ropes of cum spill over her fingers and onto my stomach. She keeps stroking me gently through every pulse, milking me until I’m completely spent, a proud little smile on her flushed face.

I sigh in satisfaction, and let myself fall onto my bed. Marie-Rose then curls up beside me on the bed, still wearing her yellow t-shirt and miniskirt. She rests her head on my chest, tracing lazy patterns with her fingertip while I catch my breath.

“I have a favour to ask… can I leave all the new lingerie here with you?” she asks quietly, almost shy again. “I can’t risk taking them home. If my parents found it… they’d be so disappointed. They still think I’m their perfect little girl.”

My breath hitches in my throat. And panic sets in. “Oh… well, I’m not sure if that’s a good idea. Wouldn’t I run into the same problem as you?” I run my fingers through her soft brown hair. “What if my own mom stumbles upon the bag in my closet when she’s cleaning or whatever? I have no idea what I could even say that wouldn’t raise further questions!”

I feel Marie-Rose heavily sigh against my chest. “Pretty please? My parents would freak out if they knew I went out and bought sexy underwear.” She sits up and looks at me, with a pleading look on her face. “You could just say they’re for a girl you want to impress from school. It’s technically true, right?”

My heart races. And I heave a sigh. Damn, she’s going to be lethal at college. “Regardless of whether it’s technically true or not, this could be a disaster waiting to…”

Marie-Rose cuts me off. “What if I sweetened the deal? How about I come over sometime… and model these pieces for you?” She gives me a sly grin. “Maybe next time you can help me take them off.”

Heat rushes through me. The idea of Marie-Rose modelling the lingerie just for me (maybe even letting me take it off) is too tempting to refuse. “Alright… fine.” I run my fingers through her soft brown hair, and sigh in both resignation and anticipation. “My mom might not even look in my closet anyway.”

She lifts her head and smiles at me, relieved and happy. “Good. Because I plan on coming over a lot.”

The promise in her voice makes my spent cock twitch with interest already. She shoots me a shit-eating grin and snuggles closer, clearly pleased with herself.
